The specific meanings of the above terms in the embodiments of the present application can be understood by those of ordinary skill in the art according to specific situations.

With the increasing environmental pollution, the environmental awareness of people is gradually strengthened, and at the moment, the new energy industry rapidly rises, so that a wide space is provided for the application and development of secondary batteries. Taking a lithium ion battery as an example, the lithium ion battery has the characteristics of high energy density, long cycle life, good charge and discharge rate performance, and the like, and is widely applied, more and more electric devices, such as mobile phones, notebook computers, electric tools, electric automobiles, and the like, select the lithium ion battery as a power source, and people generally refer to the lithium ion battery used in the electric devices as a power battery. In some cases, the power battery generally includes a box body, and a plurality of battery cells are disposed in the box body, and are distributed in a row or in a matrix.

However, the inventor further researches and discovers that, in the using process of the battery, the battery monomers can expand to a certain degree and generate heat, after the battery monomers expand, the air in the box body is compressed, and the air can also expand when heated, so that the pressure in the box body is increased, the pressure of the battery monomers in the box body is increased, and the pressure of the battery monomers in the box body is increased. And the periphery of a column of single batteries in the box body is usually provided with an end plate and a side plate, and after the single batteries expand, the end plate and the side plate are easy to deform, so that the structure is unreliable and is easy to interfere with other structures positioned around the end plate or the side plate. In addition, after a plurality of battery monomer inflation in the box, the space that the battery monomer took increases to make the gas in the box compressed, the pressure increase in the box easily leads to the box to take place deformation, for example the box probably outwards swells partial structure, the deformation of box probably makes the box and is located the distance between the box outside adjacent structure and reduce, then the condition that the structure is interfered or the electrical safety distance undersize probably appears takes place.

Based on the above consideration, in order to solve the problem that the expansion force is difficult to release after the battery cells expand, the inventors have conducted intensive studies and designed a battery case, as shown in fig. 1 to 5, which includes a case body 100 and a sliding member 200, the case body 100 having a sealed chamber therein; the sliding piece 200 is slidably arranged in the box body 100, and the sliding piece 200 is hermetically connected with the box body 100; the sliding member 200 divides the sealed chamber into a first chamber 310 and a second chamber 320, the first chamber 310 is used for accommodating the battery cell 600, and the sliding member 200 can move relative to the box body 100 to change the volume of the first chamber 310.

With such an arrangement, after the single battery 600 expands, the gas in the first chamber 310 is compressed, the pressure cavity in the first chamber 310 increases, that is, the pressure acting on the sliding member 200 increases, the pressure pushes the sliding member 200 to move, so that the volume of the first chamber 310 increases, and the volume of the second chamber 320 decreases, so that the pressure in the first chamber 310 is released, that is, the expansion force of the single battery 600 is transmitted to the sliding member 200 via the gas, so that the sliding member 200 is pushed to move, so that the expansion force generated by the expansion of the single battery 600 is released, and thus the problems of deformation of the box 100 and the like caused by the excessive expansion force can be alleviated or even avoided to a certain extent. Due to the fact that the pressure in the first chamber 310 is reduced, the pressure acting on the single cells 600 is reduced, and therefore the problem that the stress on the single cells 600 in the middle of a row of single cells 600 is greater than the stress on the single cells 600 in the end portions, that is, the stress on the single cells 600 is unbalanced, can be reduced to a certain extent.

It should be noted that after the volume of the second chamber 320 is decreased, the pressure in the second chamber 320 is gradually increased, the pressure applied to the side surface of the sliding member 200 located in the second chamber 320 is increased, and when the pressure applied to the side surface of the sliding member 200 located in the second chamber 320 is equalized with the pressure applied to the side surface of the sliding member 200 located in the first chamber 310, the sliding member 200 stops moving relative to the box 100 and stays at a new equilibrium position. Since the second chamber 320 is relatively far away from the battery cell 600 and is less affected by the expansion and heat generation of the battery cell 600 than the first chamber 310, even after the sliding member 200 moves to increase the pressure in the second chamber 320 to a certain extent, the second chamber 320 still has an influence on the case 100 that is not enough to deform the case 100.

As shown in fig. 3, the battery box is suitable for batteries, and the batteries can be battery modules or battery packs.

Illustratively, the battery box is suitable for a battery module, and one or more battery cells 600 are arranged in the first cavity 310 of the battery box.

Or, the battery box is suitable for a battery pack, and one or more battery modules are arranged in the battery box, and each battery module comprises one or more battery monomers 600; alternatively, one or more battery cells 600 are disposed directly within the battery box.

The battery cell 600 is the smallest unit constituting the battery. In the battery box, the battery cell 600 may be plural, and in the plural battery cells 600, each battery cell 600 may be a secondary battery or a primary battery; but is not limited to, a lithium sulfur battery, a sodium ion battery, or a magnesium ion battery. The battery cell 600 may be cylindrical, flat, rectangular parallelepiped, or other shapes, etc.

The plurality of battery cells 600 may be connected in series, in parallel, or in series-parallel, where in series-parallel refers to both series connection and parallel connection among the plurality of battery cells 600. The plurality of battery cells 600 can be directly connected in series or in parallel or in series-parallel, and the whole formed by the plurality of battery cells 600 is accommodated in the battery box; of course, the battery may also be a battery module formed by connecting a plurality of battery cells 600 in series, in parallel, or in series-parallel, and a plurality of battery modules are connected in series, in parallel, or in series-parallel to form a whole and accommodated in the battery box. The battery may further include other structures, for example, the battery may further include a bus member for achieving electrical connection between the plurality of battery cells 600.

The battery box provided in the embodiments of the present application is explained in detail below.

The battery box comprises a box body 100 and a sliding piece 200, wherein a sealed chamber is arranged inside the box body 100; the sliding piece 200 is slidably arranged in the box body 100, and the sliding piece 200 is hermetically connected with the box body 100; the sliding member 200 divides the sealed chamber into a first chamber 310 and a second chamber 320, the first chamber 310 is used for accommodating the battery cell 600, and the sliding member 200 can move relative to the box body 100 to change the volume of the first chamber 310.

The box body 100 is used for forming a sealed chamber, and the box body 100 may have a prism structure, a cylinder structure, or other various structural shapes.

The sliding member 200 is installed inside a sealed chamber of the box body, the sliding member 200 is used for dividing the sealed chamber into two parts, the two parts are a first chamber 310 and a second chamber 320, respectively, the sliding member 200 is connected with the box body 100 in a sealed mode, namely, in the process that the sliding member 200 moves relative to the box body 100, the contact part between the sliding member 200 and the box body 100 is sealed, and therefore even if the sliding member 200 moves relative to the box body 100, the first chamber 310 is always a sealed chamber. The second chamber 320 may also be a sealed chamber. The glides 200 may be diaphragms or baffles. For example, in fig. 1 and 2, the sliding member 200 is a partition plate made of a plate-shaped material, and the sliding member 200 has relatively high structural strength and is easily moved relative to the box 100.

Because the sliding part 200 is arranged in the box body 100, when the battery box is applied to a battery, a single battery is arranged in the first cavity 310 of the box body 100, and in the using process of the battery, after the single battery 600 expands, the sliding part 200 moves to increase the volume of the first cavity 310, so that the pressure in the first cavity 310 is released, and the problems of deformation and the like of the box body 100 caused by overlarge expansion force can be relieved or even avoided to a certain extent. In addition, the pressure in the first chamber 310 is reduced, so that the pressure acting on the battery cells 600 is reduced, and thus the stress on the battery cells 600 positioned in the middle of a row or a column of the battery cells 600 is greater than the stress on the battery cells 600 positioned at the ends, that is, the stress on the battery cells 600 is not uniform.

In some embodiments, the battery box further includes a position adjuster disposed between the box body 100 and the slider 200, the position adjuster defining an initial position of the slider 200 within the box body 100.

The initial position of the slider 200 within the box 100 is: the position of the slide 200 within the case 100 when the battery cell 600 is mounted within the case 100 and the battery cell 600 is not expanded. That is, the position of the slide 200 within the case 100 without being affected by the expansion of the battery cell 600. Since the first cavity 310 is used for accommodating the battery cell 600 and the sliding member 200 is used for separating the first cavity 310 and the second cavity 320, after the battery cell 600 expands, the sliding member 200 moves away from the battery cell 600 to increase the volume of the first cavity 310, so that when the battery cell 600 does not expand, the distance between the sliding member 200 and the battery cell 600 is the closest, and the initial position of the sliding member 200, that is, the minimum distance between the sliding member 200 and the battery cell 600, is defined by the position adjusting member. Through the restriction of the position adjusting member, a certain gap is formed between the sliding member 200 and the battery cell 600, so that the collision between the sliding member 200 and the battery cell 600 is reduced or even avoided.

In some embodiments, the pressurized gas may be filled into the first chamber 310 such that the pressure of the first chamber 310 is greater than the pressure of the second chamber 320 when the slider 200 is in the initial position, and the slider 200 is stably located in the initial position under the unequal pressures of the first chamber 310 and the second chamber 320 by the friction between the slider 200 and the case 100 and the position adjusting member. Since the pressure of the second chamber 320 is less than the pressure of the first chamber 310 when the slide 200 is in the initial position, the pressure in the second chamber 320 is increased to a certain extent after the slide 200 is moved, and the influence on the tank 100 is relatively small.

In one possible design, the first chamber 310 may be filled with a pressurized gas such that when the slide 200 is in the initial position, the pressure in the first chamber 310 is greater than atmospheric pressure and the pressure in the second chamber 320 is equal to atmospheric pressure. This arrangement, on the one hand, applies a certain pressure to the sliding member 200 from the side of the first chamber 310 to assist in maintaining the initial position of the sliding member 200, and on the other hand, after the battery cell 600 in the first chamber 310 expands, the expansion force can be transmitted to the sliding member 200 relatively faster to push the sliding member 200 to move, so that the volume of the first chamber 310 changes faster, that is, the release speed of the expansion force is faster, that is, the pressure balance adjustment response speed of the first chamber 310 is faster.

Alternatively, in another possible design, the first chamber 310 is filled with oil. In this arrangement, on one hand, the oil material can apply a certain pressure to the sliding member 200 from the side of the first chamber 310 to assist in maintaining the initial position of the sliding member 200, and after the battery cells 600 in the first chamber 310 expand, the expansion force can be relatively quickly transmitted to the sliding member 200 through the oil material to push the sliding member 200 to move, so that the volume of the first chamber 310 changes faster, that is, the release speed of the expansion force is faster, that is, the pressure balance adjustment response speed of the first chamber 310 is faster. On the other hand, the oil has a certain heat conduction function, thereby facilitating the faster dissipation of heat from the battery cell 600.

The oil may be any oil having a large specific heat and good insulation properties, such as mineral oil, for example, oil for a square-box (transformer oil) or oil for a capacitor. The square shed oil has much higher insulating strength than air, and the specific heat of the square shed oil is big, and the radiating effect is good, and the square shed oil also has the arc extinction effect, plays further guard action to battery monomer 600.

In this embodiment, the position adjustment members are used to define the initial position of the sliding member 200 in the box 100, and may be disposed in the first chamber 310 and the second chamber 320, or when there are a plurality of position adjustment members, a plurality of position adjustment members may be installed in the first chamber 310 and a plurality of position adjustment members may be installed in the second chamber 320.

In one possible design, the position adjustment member is disposed in the second chamber 320. In this design, the position adjustment member is disposed in the second chamber 320, so that the space for accommodating the battery cell 600 in the first chamber 310 is larger, which is beneficial to effectively utilize the space in the case 100.

The case 100 is used to form a sealed cavity, and in order to facilitate installation of the battery cell 600 and other devices in the sealed cavity, the case 100 may include a first portion and a second portion, the first portion and the second portion are connected to form the case 100, and the first portion and the second portion may be fixedly connected or detachably connected. For example, in one embodiment, the first portion and the second portion are both of a groove structure and respectively have a cavity, and after the first portion and the second portion are connected, the cavity of the first portion and the cavity of the second portion are communicated to form a sealed cavity. Or, in another embodiment, the first part is a main body 110, specifically a groove structure, the main body 110 has a cavity inside, the cavity is communicated with the opening of the main body 110, the second part is a cover 120, the cover 120 is a plate structure for covering the opening of the main body 110, and the battery cell 600 and other structures can be installed in the sealed cavity from the opening. The cover 120 may be located on a side surface of the box 100, or may be located on a top surface or a bottom surface of the box 100, based on an installation angle of the box 100 in an operating state.

Illustratively, as shown in fig. 2 and 5, in one possible design, the box 100 includes a main body 110 and a cover 120, the main body 110 has a top opening, the top opening is communicated with the cavity, the cover 120 covers the top opening, the cover 120 and the main body 110 enclose to form a sealed chamber, and the position adjusting member is disposed between the cover 120 and the sliding member 200.

The main body 110 has a side plate and a bottom plate, the side plate and the bottom plate enclose a cavity, and an opening is provided at the top of the main body 110, and the opening is called a top opening.

The cover 120 has a plate-like structure and covers the top opening of the main body 110. The cover 120 and the body 110 may be hermetically connected.

The sliding member 200 is disposed between the cover 120 and the bottom plate of the main body 110, the upper regions of the side plates of the sliding member 200, the cover 120 and the main body 110 are enclosed to form a second chamber 320, the lower regions of the side plates of the sliding member 200, the main body 110 and the main body 110 are enclosed to form a first chamber 310, and the sliding member 200 moves up and down relative to the side plates of the main body 110, so that the volumes of the first chamber 310 and the second chamber 320 are changed.

It should be noted that, since the sliding member 200 is connected to the box 100 (specifically, the main body 110) in a sealing manner, the first chamber 310 is a sealed chamber. The second chamber 320 is also a sealed chamber when the cover 120 is hermetically connected to the main body 110, and the second chamber 320 is an unsealed chamber when the cover 120 is not hermetically connected to the main body 110.

In the case body 100 structure, when the single battery 600 is placed in the case body 100, the single battery 600 may be placed in the cavity of the main body 110 from the top opening, and then the sliding member 200 is placed in the top opening, so that the sliding member 200 is located above the single battery 600, so that after the sliding member 200 divides the cavity into two parts, the single battery 600 is located in the first cavity 310 below, and then the position adjusting member and the cover 120 are installed. That is, the case 100 and the battery cells 600 inside the case are easily mounted due to the structure of the case 100. The connection point of the cover 120 and the main body 110 is located above the first chamber 310, that is, located in the area corresponding to the second chamber 320, so that the first chamber 310 has better sealing performance.

In addition, in the arrangement mode that oil is filled in the first cavity 310, the oil is located in the first cavity 310, and the connection part of the cover body 120 and the main body 110 is located in the second cavity 320, so that the sealing effect on the oil can be further improved, and the oil is relieved to a certain extent or even prevented from overflowing due to shaking or overlarge pressure in the box body 100.

When high-pressure gas needs to be filled into the first cavity 310, the joint of the cover 120 and the main body 110 is located in the second cavity 320, and the high-pressure gas is located in the first cavity 310, so that the sealing effect on the high-pressure gas can be further improved, and the leakage of the high-pressure gas at the joint of the cover 120 and the main body 110 can be reduced or even avoided to a certain extent.

The cover 120 and the body 110 can be connected by various connecting methods such as welding, bonding, screwing and the like.

Illustratively, in one embodiment, the cover 120 is screwed to the body 110. As shown in fig. 2 and 5, a flange 111 is outwardly disposed at an edge of a top opening of the main body 110, a first mounting hole 112 is disposed on the flange 111, a second mounting hole 121 is disposed on the cover 120, and after the flange 111 is covered with the cover 120, the first mounting hole 112 and the second mounting hole 121 are correspondingly communicated one to one, and pass through the first mounting hole 112 and the second mounting hole 121 through bolts, so as to connect the cover 120 with the main body 110. The flange 111 is provided to increase a contact area between the cover 120 and the main body 110, and to provide the first mounting hole 112.

In an alternative embodiment, a sealing gasket may be disposed between the main body 110 and the cover 120, and the sealing gasket surrounds the joint between the main body 110 and the cover 120, so as to improve the sealing effect at the joint between the main body 110 and the cover 120.

As shown in fig. 2, in one possible design, the slide 200 is provided with a through hole 210, and an explosion-proof valve 220 (shown in fig. 2 and 5) is provided in the through hole 210. The explosion-proof valve 220 is adapted to open when the pressure in the first chamber 310 exceeds a threshold value, thereby allowing the pressure in the first chamber 310 to quickly release into the second chamber 320 to further mitigate the double protection of the battery by the explosion-proof valve 220 and the slide 200. The explosion proof valve 220 may include an explosion proof diaphragm installed at the through-hole 210 to block the through-hole 210, and the slider 200 moves to increase the volume inside the first chamber 310 at the initial stage of the expansion of the battery cell 600, thereby reducing the pressure of the first chamber 310. If the expansion speed of the battery cell 600 is too high or the battery cell is overheated, and the moving speed of the sliding member 200 is not high enough to quickly release the pressure of the first chamber 310, the pressure acting on the explosion-proof membrane increases, and when the pressure exceeds a threshold value, the explosion-proof membrane is broken, so that the first chamber 310 is communicated with the second chamber 320, and therefore gas or oil in the first chamber 310 quickly enters the second chamber 320 through the through hole 210 to realize the pressure release of the first chamber 310. The threshold value of whether the explosion-proof membrane is broken or not can be adjusted by changing the thickness or the material of the explosion-proof membrane. For example, the larger the thickness of the explosion-proof membrane made of the same material is, the higher the threshold value is. Alternatively, the threshold value can also be reduced by providing a groove in the rupture disk.

In one possible design, the circumferential side of the glide 200 is provided with a second sealing ring, which is located between the glide 200 and the inner wall of the tank 100. When the box 100 includes a main body 110 and a cover 120, the sliding member 200 is slidably mounted on a side plate of the main body 110 and located between the cover 120 and a bottom plate. The second sealing ring is disposed on a side surface of the sliding member 200, and the second sealing ring is located between the sliding member 200 and a side plate of the main body 110. In the process that the sliding member 200 moves relative to the side plate of the main body 110, the second sealing ring moves along with the sliding member 200, so that the second sealing ring always has a sealing effect between the sliding member 200 and the side plate of the main body 110. The sealing ring can be made of materials which have certain flexibility, water resistance and oil resistance, such as rubber or silica gel.

In one possible design, the thickness of the edge region of glide 200 is less than the thickness of the middle region of glide 200.

The sliding member 200 has two opposite surfaces, one of which is located in the first chamber 310, and the other of which is located in the second chamber 320, and is used for connecting the two surfaces, namely the side surface of the sliding member 200, and the side surface of the sliding member 200 is in contact with the inner wall of the box 100. In the sliding member 200, the region close to the side surface is an edge region, and the region far from the side surface is a middle region.

In this design, the middle of the sliding member 200 has a relatively larger thickness, so the sliding member 200 has a relatively stronger structural strength, and the edge of the sliding member 200 contacts the inner wall of the box 100 and has a smaller thickness, so the contact area between the sliding member 200 and the box 100 is relatively smaller, and the sliding member 200 is convenient to move relative to the box 100.

As shown in fig. 5, an edge region of one side of the slide 200 located in the first chamber 310 is a bevel 230, and the thickness of the edge region of the slide 200 is smaller than that of the middle region by the bevel 230. Taking the direction in fig. 5 as an example, one of two opposite surfaces in the sliding member 200 is a top surface, and the other is a bottom surface, and an inclined surface 230 is arranged at the edge of the bottom surface, and taking the sliding member 200 with a rectangular plate-shaped structure in fig. 5 as an example, an inclined surface 230 inclined to the left and the upper is arranged at the left side edge of the bottom surface, so that the thickness of the edge region on the left side of the sliding member 200 is gradually increased from the left to the right; a slope 230 inclined upward and rightward is provided at the right side edge region of the bottom surface so that the thickness of the right side edge region of the slide 200 gradually increases from right to left. Between the inclined surface 230 on the left side of the bottom surface and the inclined surface 230 on the right side of the bottom surface is a flat surface, which corresponds to the middle region of the glide 200.

As shown in fig. 5, in a possible design, the battery box further includes a first guide 510 and a second guide 520, one of the first guide 510 and the second guide 520 is mounted on the box body 100, the other is mounted on the sliding member 200, and the first guide 510 is connected with the second guide 520 in a sliding fit manner.

In this design, the cooperation of the first guide 510 and the second guide 520 guides the movement of the sliding member 200, so that the sliding member 200 is more stable during the movement.

In one embodiment, the first guide 510 is mounted to the box 100, the second guide 520 is mounted to the sliding member 200, and the second guide 520 is moved relative to the first guide 510 by the sliding member 200 during the movement of the sliding member 200 relative to the box 100.

When the case 100 includes the body 110 and the cover 120, the first guide 510 is mounted to the cover 120, and the second guide 520 is mounted to the slider 200.

The first guide 510 is slidably engaged with the second guide 520, the structure of the first guide 510 is matched with the structure of the second guide 520, and the first guide 510 and the second guide 520 may have various structures. For example, one of the first guide 510 and the second guide 520 may be a slide rail, and the other may be a slider, and the slider is slidably mounted on the slide rail. Alternatively, one of the first guide 510 and the second guide 520 may be a guide post, and the other may be a guide cylinder provided with a guide groove, and the guide post extends into the guide groove of the guide cylinder.

Or, in another possible design, the first guide 510 and the second guide 520 are both cylindrical structures, the first guide 510 is sleeved outside the second guide 520, the first guide 510 and the second guide 520 form an accommodating cavity 530, and the position adjusting member is disposed in the accommodating cavity 530.

The first guide 510 and the second guide 520 are both cylindrical structures, and specifically, the structural shape of the inner cavity of the first guide 510 is matched with the structural shape of the outer contour of the second guide 520, so that after the first guide 510 is sleeved outside the second guide 520, the relative movement between the second guide 520 and the first guide 510 is smoother. For example, the first guide 510 and the second guide 520 may each be a cylinder, a square cylinder, or the like.

In this design, the position adjustment member is disposed in the accommodating cavity 530, so that on one hand, the installation space is saved, and on the other hand, the first guide member 510 and the second guide member 520 protect the position adjustment member.

Alternatively, as shown in fig. 6, in order to increase the structural strength of the first guide 510 and the second guide 520, a first reinforcing rib 511 is connected to the outside of the first guide 510, and a second reinforcing rib 521 is connected to the outside of the second guide 520. When the first guide 510 is mounted on the cover 120 and the second guide 520 is mounted on the slide 200, the end surface of the first guide 510 is connected to the cover 120, the first rib 511 is connected to the cover 120, the end surface of the second guide 520 is connected to the slide 200, and the second rib 521 is connected to the cover 120.

The first guide 510, the first reinforcing bead 511, and the cover body 120 may be connected as an integral structure, or manufactured by an integral molding process. The second guide 520, the second reinforcing rib 521 and the sliding member 200 may be connected as an integral structure or manufactured by an integral molding process.

In one possible design, the first guide 510 is provided with a first seal 540, the first seal 540 being located between the first guide 510 and the second guide 520.

In this design, the first sealing ring 540 is disposed to increase the radial friction between the first guide 510 and the second guide 520, and reduce or even avoid the relative shake between the first guide 510 and the second guide 520, so as to improve the stability during the relative movement of the first guide 510 and the second guide 520.

The first sealing ring 540 may be made of a material having a certain elasticity, such as silicone rubber or rubber.

In an alternative embodiment, a first seal 540 is disposed at the end of the first guide 510. So configured, in the process that the sliding member 200 moves the first guide 510 to reduce the volume of the second chamber 320, the sliding member 200 moves to a direction close to one side of the box 100. For example, when the box 100 includes the main body 110 and the cover 120, and the second chamber 320 is formed between the sliding member 200 and the cover 120, the sliding member 200 drives the first guide 510 to move toward the cover 120, because the end of the first guide 510 is provided with the first sealing ring 540, the first sealing ring 540 moves toward the cover 120 along with the first guide 510, and before the first guide 510 contacts the cover 120, the first sealing ring 540 contacts the cover 120, and the first sealing ring 540 may also play a role in buffering between the first guide 510 and the cover 120.

In this embodiment, the position adjusting member may be disposed in various ways, for example:

as shown in fig. 5, in a possible design, the position adjusting member includes a latch 411, one of the case 100 and the sliding member 200 is provided with the latch 411, the other is provided with a slot 412, an end of the latch 411 is located in the slot 412, and the latch 411 can move within a certain range relative to the slot 412.

In this design, during the movement of the slider 200 relative to the case 100, the latch 411 moves relative to the latch slot 412, and since the latch 411 can only move in a certain range relative to the latch slot 412, the slider 200 is limited to move in a certain range relative to the case 100.

For example, as shown in fig. 5, the cross section of the fixture block 411 is a cylinder, the fixture block 411 includes a head portion and a neck portion connected to each other, the diameter of the head portion of the fixture block 411 is larger than the diameter of the neck portion of the fixture block 411, the clamping groove 412 has a closed opening, the caliber of the closed opening is smaller than the inner diameter of the non-closed portion of the clamping groove 412, and the diameter of the head portion of the fixture block 411 is larger than the caliber of the closed opening of the clamping groove 412 and smaller than the inner diameter of the non-closed portion of the clamping groove 412. The extending direction (groove depth direction) of the catching groove 412 is the same as the moving direction of the slider 200. With such an arrangement, in the extending direction of the slot 412, the latch 411 can move relative to the slot 412, and due to the limitation of the closed opening, the latch 411 cannot be completely separated from the slot 412, so that when the latch 411 contacts with the slot 412 at the edge of the closed opening, the position of the sliding member 200 is the position when the distance between the sliding member 200 and the cover 120 is the maximum.

Optionally, the latch 411 and the latch slot 412 are both disposed in the receiving cavity 530. The sliding member 200 is provided with a first fastening member 413, an opening is formed on one side of the fastening member facing the cover 120, an inner cavity of the first fastening member 413 is the slot 412, and an opening of the first fastening member 413 is a closing opening of the slot 412. The top end of the latch 411 is connected to the cover 120, and the head of the latch 411 is located in the slot 412.

In another possible design, the position adjusting member includes an elastic body 420, and both ends of the elastic body 420 are respectively connected to the inner wall of the casing 100 and the slide member 200.

The elastic body 420 is a structure having elasticity, such as a spring, a leaf spring, or a block structure made of an elastic material.

In this embodiment, the elastic body 420 defines the movement range of the sliding member 200 on one hand and plays a certain role in restoring the sliding member 200 on the other hand.

In addition, when the first chamber 310 is filled with high-pressure gas or oil, the elastic body 420 is disposed, so that one side of the sliding member 200 is subjected to the pressure of the high-pressure gas or oil, and the other side of the sliding member is subjected to the pressure of the elastic body 420, when the pressures at the two sides reach a balance, the position where the sliding member 200 is balanced in the box 100 is the initial position of the sliding member 200. So set up, the setting of elastomer 420 can make glide 200 better keep in initial position, alleviates or even avoids glide 200 to rock or shake because of box 100 rocks etc. factor appearance.

In an alternative embodiment, as shown in fig. 7, the elastic body 420 is a spring, and the elastic body 420 is located in a receiving cavity 530 formed by the first guide 510 and the second guide 520.

The extending direction of the position-limiting column 421 is the same as the moving direction of the sliding member 200, and in the moving direction of the sliding member 200, the size of the position-limiting column 421 is smaller than or equal to the minimum value of the size of the accommodating cavity 530.

In yet another possible design, as shown in fig. 9, the position adjusting member includes a piston 431, one of the inner wall of the case 100 and the slide member 200 is provided with a piston chamber 432, and the other is provided with the piston 431, and one end of the piston 431 extends into the piston chamber 432.

In this design, when the sliding member 200 moves to decrease the second chamber 320, the portion of the piston 431 extending into the piston chamber 432 increases, so that the gas in the piston chamber 432 is compressed, the pressure in the piston chamber 432 increases, and after the expansion force in the first chamber 310 decreases, the compressed gas in the piston chamber 432 pushes the piston 431 to move outward, so that the sliding member 200 moves to decrease the volume of the first chamber 310, and by the arrangement of the piston 431, the pressures in the first chamber 310 and the second chamber 320 on both sides of the sliding member 200 are in a relatively balanced state, so that the sliding member 200 is stably located at the initial position, and the shaking or shaking of the sliding member 200 due to the shaking or the like of the tank 100 is reduced or even avoided.

Exemplarily, in fig. 9, the piston 431 and the piston cavity 432 are both located in the accommodating cavity 530, a second fastening member 433 is disposed on the sliding member 200, the second fastening member 433 has a blind hole, an opening of the blind hole faces the cover 120, the blind hole is the piston cavity 432, one end of the piston 431 extends into the piston cavity 432, and the other end of the piston 431 is connected to the cover 120. The second fastening member 433 and the sliding member 200 may be an integral structure, and the cover 120 and the piston 431 may be an integral structure.

In another possible design, the position adjusting member includes a protrusion 441 and a sleeve 442, one of the sleeve 442 and the protrusion 441 is mounted on the case 100, the other is mounted on the sliding member 200, the sleeve 442 is sleeved on the protrusion 441, a pressure chamber 443 is defined between the sleeve 442 and the protrusion 441, and the pressure chamber 443 is a first pressure.

So set up, the setting of pressure chamber 443 can make sliding member 200 better keep in initial position, alleviates even avoids sliding member 200 to rock or shake because of factors such as box 100 rocks.

Since the pressure inside the first chamber 310 is greater than the atmospheric pressure after the high-pressure gas or oil is filled in the first chamber 310, the first pressure inside the pressure chamber 443 is at least greater than the atmospheric pressure. The specific setting of the first pressure may be set according to a pressure required when the moving member is at the set initial position after the first chamber 310 is filled with the high-pressure gas or oil.
