In some embodiments of the present application, the driving assembly includes a lever, a first elastic member, and a driving member. The blocking rod is arranged in the accommodating groove, arranged on one side of the supporting plate along the direction parallel to the second surface and the third surface and rotatably connected with the side wall of the accommodating groove. Under the condition that the supporting plate is located the holding tank, the one end that the holding tank bottom was kept away from to the shelves pole is with the backup pad joint to prevent the backup pad to slide outward to the holding tank. The first elastic piece is arranged in the accommodating groove and is abutted between the supporting plate and the groove bottom of the accommodating groove. The driving part is arranged in the accommodating groove and is positioned at one end of the stop lever close to the bottom of the accommodating groove and far away from one side of the supporting plate; the driving piece is used for pushing one end, close to the bottom of the accommodating groove, of the gear rod along the direction close to the supporting plate so that the gear rod is separated from the supporting plate from the clamping position. Under the condition that the supporting plate is positioned in the accommodating groove, the supporting plate can stay in the accommodating groove through the mutual clamping of the blocking rod and the supporting plate; when the supporting plate is required to support, the gear lever can be driven by the driving piece to rotate towards the direction close to the supporting plate, and at the moment, one end of the gear lever, far away from the bottom of the accommodating groove, rotates towards the direction far away from the supporting plate, so that the gear lever and the supporting plate can be separated from the clamping position; after the gear lever is separated from the supporting plate, the supporting plate can slide out of the accommodating cavity under the action of the first elastic piece, so that the supporting plate is supported, the supporting area of the base is increased, and the supporting stability is improved.

In some embodiments of the present application, the blocking rod comprises a rod body and a first permanent magnet, the first permanent magnet is disposed at an end of the rod body near a bottom of the accommodating groove and is connected to the rod body as an integral structure, and the first permanent magnet comprises a first pole and a second pole. The driving piece comprises an electromagnet, the electromagnet is fixed in the accommodating groove and comprises a third pole and a fourth pole, the first pole and the third pole are arranged oppositely, and the polarities of the first pole and the third pole are the same. The driving assembly further comprises a second elastic piece, the second elastic piece is arranged in the accommodating groove, the second elastic piece is located at one end, away from the bottom of the accommodating groove, of the blocking rod and is far away from one side of the supporting plate, and the second elastic piece is used for enabling the blocking rod to rotate towards the direction close to the supporting plate at one end, away from the bottom of the accommodating groove, of the blocking rod. Thus, through switching on the electro-magnet, make the electro-magnet produce magnetism, because the third pole of electro-magnet sets up with the first utmost point of first permanent magnet relatively, and the polarity is the same, consequently, under the effect that like poles repel each other, first permanent magnet can drive the pole body and be close to the one end of holding tank bottom and rotate to the direction that is close to the backup pad, the one end that the holding tank bottom was kept away from to the pole body promptly rotates to the direction of keeping away from the backup pad, thereby can make shelves pole and backup pad break away from the joint position, and then make the backup pad can slide out the holding tank under the elastic force effect of first elastic component, it is more simple and convenient to use. And, after the electro-magnet outage, magnetic force disappears, and the repulsion that promotes first permanent magnet and remove promptly disappears, and at this moment, second elastic component makes the pole body keep away from the one end of holding tank bottom and rotates to the direction that is close to the backup pad under the spring action, even shelves pole resets to when being convenient for the backup pad withdraws to in the holding tank, shelves pole and backup pad mutual joint once more.

The cover plate 200 and the display device 20 are attracted by the magnetic force between the permanent magnets, so that the display device 20 is more convenient to disassemble and assemble.

As shown in fig. 5, the third permanent magnet 220 may be fixed to the first surface 210 of the cover plate 200, and as shown in fig. 6, the fourth permanent magnet 201 may be fixed to the back surface of the display device 20 (i.e., the surface where the display device 20 is attached to the first surface 210), so that the third permanent magnet 220 and the fourth permanent magnet 201 are attracted to each other, that is, the display device 20 may be fixed to the first surface 210 of the cover plate 200.

In order to make the overall structure more beautiful, as shown in fig. 7, the third permanent magnet 220 may be embedded in the cover plate 200, and the fourth permanent magnet 201 may be fixed in the housing of the display device 20, so that the third permanent magnet 220 and the fourth permanent magnet 201 cannot be directly seen from the external structure. In this way, the cover plate 200 and the display device 20 can be connected to each other by the permanent magnet, and the overall appearance can be improved.

On the basis, as shown in fig. 8, the base 100 further includes a receiving groove 130, the base 100 further has a third surface 120, the third surface 120 is perpendicular to the second surface 110, the third surface 120 is parallel to the plane XOZ, and the third surface 120 is disposed at a side close to the rotating member 800. The receiving groove 130 is opened on the third surface 120. As shown in fig. 9, the keyboard support 10 provided by the present application further includes a supporting plate 400 and at least one driving assembly 500 disposed in the receiving groove 130, and the supporting plate 400 is slidably disposed in the receiving groove 130, wherein the third surface 120 in fig. 9 is projected as a straight line due to the front view along the Z direction in fig. 9. As shown in fig. 10, at least one driving assembly 500 is used to drive a portion of the support plate 400 to slide out of the receiving groove 130 (as shown in fig. 8).

That is, the central line of the supporting plate 400 is parallel to the sliding direction of the supporting plate 400, and two sets of driving assemblies 500 are disposed on two sides of the central line of the supporting plate 400, so that the supporting plate 400 is not inclined and swayed in the sliding process, thereby ensuring that the supporting plate 400 can smoothly slide out or slide into the accommodating groove 130.

The keyboard support 10 provided by the present application, because the supporting plate 400 is disposed inside the base 100 and can slide out from the rear sidewall of the base 100, that is, the supporting plate 400 is added on the rear side of the base 100 to increase the supporting area of the base 100. Meanwhile, under the condition that the area of the keyboard 300 is not occupied or reduced, the cover plate 200 and the display device 20 borne by the cover plate 200 can be stably supported, so that the situation that the whole support is unstable or the keyboard is inclined towards the rear side due to the fact that the weight of the display device 20 is larger than that of the base 100 and the keyboard 300 can be avoided.

A specific structure of the driving unit 500 of the electronic device 01 will be described below by way of example.

Example 1

In this example, as shown in fig. 12, the driving assembly 500 provided by the present application includes a lever 510, a first elastic member 520, and a driving member 530. The blocking rod 510 is disposed in the receiving groove 130, and the blocking rod 510 is disposed at one side of the supporting plate 400 along a direction parallel to the rotation axis and parallel to the second surface 110; when the supporting plate 400 is located in the receiving groove 130, an end of the blocking rod 510 away from the bottom of the receiving groove 130 (hereinafter referred to as a first end of the blocking rod 510) is engaged with the supporting plate 400, and the blocking rod 510 is rotatably connected to the sidewall of the receiving groove 130. The first elastic element 520 is disposed in the receiving groove 130 and abuts between the bottoms of the receiving grooves 130 of the supporting plate 400. The driving member 530 is disposed in the receiving groove 130, and the driving member 530 is located at one end of the blocking bar 510 close to the bottom of the receiving groove 130 (hereinafter referred to as the second end of the blocking bar 510) and away from one side of the supporting plate 400; the driving member 530 is used to push the second end of the lever 510 in a direction close to the support plate 400 so as to disengage the lever 510 from the support plate 400 from the clamping position.

Therefore, the supporting plate 400 can stay in the accommodating groove 130 by mutually clamping the blocking rod 510 and the supporting plate 400; then, as shown in fig. 13, the driving member 530 is controlled such that the driving member 530 pushes the second end of the blocking lever 510 to rotate in a direction approaching the supporting plate 400, and the first end of the blocking lever 510 rotates in a direction away from the supporting plate 400, so that the blocking lever 510 and the supporting plate 400 are separated from each other from the engaging position, and the resistance for preventing the supporting plate 400 from sliding disappears, and further the elastic force F of the first elastic member 520 is released₁Under the action, the supporting plate 400 can slide out of the receiving groove 130 to support the keyboard support 10.

In some embodiments, as shown in fig. 14, the lever 510 includes a lever body 511 and a first permanent magnet 512, the first permanent magnet 512 is disposed at the second end of the lever body 511 and is connected with the lever body 511 to form an integral structure, and the first permanent magnet 512 includes a first pole 5121 and a second pole 5122; as shown in fig. 15, the driving member 530 includes an electromagnet 531, the electromagnet 531 is fixed in the receiving groove 130, and the electromagnet 531 includes a third pole 5311 and a fourth pole 5312; the third pole 5311 is opposite to the first pole 5121 and has the same polarity. Then, as shown in fig. 16, the electromagnet 531 is energized to generate magnetism in the electromagnet 531. Since the third pole 5311 of the electromagnet 531 is disposed opposite to the first pole 5121 of the first permanent magnet 512 and has the same polarity, a repulsive force F is generated between the electromagnet 531 and the first permanent magnet 512₂. Since the electromagnet 531 is fixed and the lever body 511 is rotatably coupled to the sidewall of the receiving groove 130, as shown in fig. 17, a repulsive force F between the electromagnet 531 and the first permanent magnet 512 is generated₂The first permanent magnet 512 is pushed to drive the second end of the rod body 511 to rotate towards the side close to the supporting plate 400, so that the first end of the rod body 511 rotates towards the direction far away from the supporting plate 400, the clamping position between the rod body 511 and the supporting plate 400 is separated from each other, and the supporting plate 400 is enabled to be under the elastic force F of the first elastic member₁Slide out of the accommodating groove 130 under action

In order to reduce the thickness dimension (i.e., the dimension along the Z direction) of the base 100, the stop lever 510 can be rotatably connected to the sidewall parallel to the second surface 110 in the receiving groove 130. Thus, the blocking rod 510 can rotate in a plane parallel to the second surface 110, and during the rotation process, the side wall parallel to the second surface 110 in the receiving groove 130 will not block the rotation, so that the thickness of the base 100 can be reduced, the base 100 is thinner, and the overall appearance is better.

Moreover, after the electromagnet 531 is powered off, in order to timely reset the shift lever 510, as shown in fig. 18, the driving assembly 500 further includes a second elastic member 540, the second elastic member 540 is disposed in the accommodating groove 130, the second elastic member 540 is disposed at the first end of the lever body 511 and is disposed at a side of the lever body 511 away from the supporting plate 400, and the second elastic member 540 is used for rotating the first end of the lever body 511 toward the direction close to the supporting plate 400. That is, when the first end of the lever body 511 is rotated in a direction away from the support plate 400, the second elastic member 540 compresses the lever body 511, and when the electromagnet 531 is turned off, the repulsive force between the electromagnet 531 and the first permanent magnet 512 disappears, and at this time, the elastic force F of the second elastic member 540₃Under the action, the first end of the rod body 511 rotates towards the direction close to the support plate 400, so that the stem body is reset, and the stem body and the support plate 400 are clamped with each other.

The electromagnet 531 may be set to be powered on for a certain time and then automatically powered off, for example, for 2 seconds. When the electromagnet 531 is energized for 2s, it is automatically de-energized, so that the lever body 511 is reset by the second elastic member 540. Or after the user controls the electromagnet to be powered on, the electromagnet is controlled to be powered off, for example, the electromagnet 531 is controlled to be powered on and powered off through a key switch. Therefore, the present application is not particularly limited thereto.

On this basis, as shown in fig. 19, the supporting plate 400 includes a plate body 410 and a first protrusion 420, and the first protrusion 420 is disposed on a side wall of the plate body 410 facing the rod body 511 and is connected with the plate body 410 to form an integral structure. As shown in fig. 20, the blocking lever 510 further includes a second protrusion 513, the second protrusion 513 is disposed at the first end of the lever body 511 and is connected to the lever body 511 as an integral structure, and the second protrusion 513 and the second elastic member 540 are disposed at two sides of the lever body 511 respectively. With the plate body 410 in the receiving groove 130, the second protrusion 513 abuts on a surface of the first protrusion 420 away from the bottom of the receiving groove 130. In this way, the second protrusion 513 blocks the first protrusion 420, so that the blocking plate body 410 slides out of the receiving groove 130. When the lever body 511 rotates, the first end of the lever body 511 and the second protrusion 513 rotate in a direction away from the plate body 410, so that the second protrusion 513 is separated from the first protrusion 420, and the plate body 410 can slide out of the receiving groove 130 under the elastic force of the first elastic member 520.

In order to facilitate the board body 410 to be retracted into the receiving groove 130, as shown in fig. 20, a surface of the first protrusion 420 close to the bottom of the receiving groove 130 is a first guiding inclined surface 421, a surface of the second protrusion 513 away from the bottom of the receiving groove 130 is a second guiding inclined surface 5131, and the first guiding inclined surface 421 and the second guiding inclined surface 5131 are parallel to each other. As shown in fig. 21, the distance between the edge of the second guiding inclined plane 5131 close to the plate body 410 and the bottom of the receiving groove 130 is the first distance H₁The distance between the edge of the second guiding inclined plane 5131 far away from the plate body 410 and the bottom of the receiving groove 130 is the second distance H₂First distance H₁Less than the second distance H₂. Thus, when the plate body 410 slides into the receiving groove 130 until the first protrusion 420 abuts against the second guiding inclined surface 5131 of the second protrusion 513, the first protrusion 420 slides along the second guiding inclined surface 5131 and can push the second guiding inclined surface 5131 to make the second protrusion 513 move away from the plate body 410And (4) rotating. When the first protrusion 420 slides over the second guiding slope, the rod body 511 and the second protrusion 513 are restored under the elastic force of the second elastic member 540 and abut against the surface of the first protrusion 420 away from the bottom of the receiving groove 130, so as to prevent the supporting plate 400 from sliding out of the receiving groove 130.

In addition, when the first guiding inclined surface 421 abuts against the second guiding inclined surface 5131, the two surfaces contact each other, that is, the contact area is large, so that the pressure of the contact surface is small, and the first guiding inclined surface 421 slides along the second guiding inclined surface 5131 more easily, which is more beneficial to saving labor.

Specifically, as shown in fig. 22, when the user applies an external force F to the plate body 410 protruding out of the receiving groove 130, the direction of the external force F is toward the inside of the receiving groove 130. At this time, as shown in fig. 23, the plate body 410 and the first projection 420 slide into the receiving groove 130, and the first projection 420 and the second projection 513 abut against each other. Then, the plate body 410 and the first protrusion 420 continue to slide toward the inside of the receiving groove 130, the external force F is applied to the second protrusion 513, and the first protrusion 420 slides along the second guide inclined surface 5131. At this time, since the second projection 513 cannot move in the direction of the external force F and the second guide inclined surface 5131 is an inclined surface, the external force F generates a component force F perpendicular to the external force F on the second guide inclined surface 5131 as shown in fig. 24₄The component force F₄In a direction away from the plate body 410. Therefore, in the component force F₄The second projection 513 can be rotated in a direction away from the plate body 410. Then, as shown in FIG. 25, after the first projection 420 slides over the second guide inclined surface 5131, a component force F is applied to the second projection 513₄When the elastic force F of the lever body 511 on the second elastic member 540 disappears₃Acting in a direction approaching the plate body 410. Meanwhile, the user withdraws the external force F, and since the first elastic member 520 is compressed, the panel body is subjected to the elastic force F of the first elastic member 520 at this time₁The function of (1). Thus, as shown in fig. 26, the second protrusion 513 and the lever body 511 are restored, and the first protrusion 420 is restored at the elastic force F of the first elastic member 520₁Is abutted against the surface of the second protrusion 513 close to the bottom of the accommodating groove 130, i.e. the second protrusion 513 blocksThe first protrusion 420 and the plate body 410 slide outward of the receiving groove, so that the support plate 400 is retracted into the receiving groove 130.

In some embodiments, as shown in fig. 26, the first elastic member 520 may be a first spring, one end of the first spring is fixed to the supporting plate 400, and the other end of the first spring is fixed to the bottom of the receiving groove 130. Thus, when the support plate 400 is retracted into the receiving cavity, the first spring is compressed, and the support plate 400 is subject to the elastic force of the first spring. When the first protrusion 420 and the second protrusion 513 are separated from each other, the elastic force of the first spring can make the support plate 400 slide out of the receiving groove 130. In addition, the spring is a common elastic part and is low in price, so that the spring is convenient to replace and is beneficial to reducing the cost.

In some embodiments, as shown in fig. 26, the second elastic member 540 may be a second spring, one end of which is connected to the sidewall of the lever body 511, and the other end of which is connected to the sidewall of the receiving groove 130. Thus, when the electromagnet 531 is energized to generate magnetism, and the first permanent magnet 512 drives the lever body 511 to rotate, the end of the lever body 511 away from the bottom of the accommodating slot 130 rotates in a direction away from the supporting plate 400, and at this time, the second elastic element 540 is compressed. When the electromagnet 531 is deenergized, the magnetic force of the electromagnet 531 disappears, the repulsive force between the electromagnet 531 and the first permanent magnet 512 disappears, and the lever body 511 is reset by the elastic force of the second elastic member 540. In addition, the spring is a common elastic part and is low in price, so that the spring is convenient to replace and is beneficial to reducing the cost.

In addition, as shown in fig. 27, the keyboard support 10 further includes a guide bar 550, the guide bar 550 is disposed in the receiving groove 130, and a portion of the second elastic member 540 (i.e., the second spring) is sleeved on the guide bar 550. One end of the guide rod 550 is connected to the rod body 511, and the other end has a gap with the sidewall of the receiving groove 130; or one end of the guide bar 550 is connected to the sidewall of the receiving groove 130 and the other end has a gap with the bar body 511. When the first end of the lever body 511 rotates and compresses the second elastic member 540, the second elastic member 540 can be compressed along the length direction of the guide lever 550 to prevent the second elastic member 540 from bending, which is beneficial to protecting the second elastic member 540 from being damaged. In this example, as shown in fig. 28, the guide lever 550 is provided on the lever body 511, and is connected to the lever body 511 as an integral structure.

Moreover, a gap is formed between the guide rod 550 and the rod body 511 or between the guide rod 550 and the side wall of the accommodating groove 130, so that when the rod body 511 rotates, the guide rod 550 is prevented from abutting between the rod body 511 and the side wall of the accommodating groove 130, and the normal rotation of the rod body 511 is ensured.

In order to further facilitate the use of the keyboard support 10, as shown in fig. 29, the keyboard support 10 provided by the present application further includes a sensing assembly 600 and a control module 700, the sensing assembly 600 is disposed between the cover plate 200 and the base 100, the sensing assembly 600 is electrically connected to the control module 700, and the control module 700 is electrically connected to the electromagnet 531. Therefore, whether the cover plate 200 is separated from the base 100 or not can be detected through the sensing assembly 600, when the cover plate 200 is detected to be separated from the base 100, that is, the cover plate 200 is turned upwards, the sensing assembly 600 sends a signal to the control module 700, the control module 700 supplies power to the electromagnet 531, and then the supporting plate 400 can slide out of the accommodating groove 130. Therefore, when the user uses the cover plate 200, the cover plate can be turned upwards, the support plate 400 can be synchronously slid out of the accommodating groove 130, the user does not need to manually operate, and the use experience of the user is improved.

The sensing assembly 600 may employ a hall sensor 610, an infrared receiving transmitter, or a light sensor, etc. For example, the magnetic flux of the permanent magnet may be detected by the hall sensor 610, and when the distance between the two increases, the magnetic flux detected by the hall sensor 610 may decrease or disappear, and at this time, it is determined that the cover plate 200 is separated from the base 100; for another example, when the infrared receiver and the infrared transmitter are used, since infrared rays are transmitted in a straight line, when the cover plate is separated from the base, an included angle is formed between the cover plate and the base, and at this time, the infrared receiver cannot receive an infrared signal transmitted by the infrared transmitter, and thus, it can be determined that the cover plate 200 is separated from the base 100; for another example, when the cover plate 200 is fastened to the base 100 using the optical sensor, natural light cannot penetrate through the cover plate 200, and thus the optical sensor located between the base 100 and the cover plate 200 cannot detect the natural light, and when the cover plate 200 is turned upward, natural light is incident between the base 100 and the cover plate 200, and thus the optical sensor can detect the natural light, and it is determined that the cover plate 200 and the base 100 are separated from each other.

Specifically, as shown in fig. 30, in the case that the sensing assembly 600 provided by the present application employs the hall sensor 610 and the second permanent magnet 620, one of the hall sensor 610 and the second permanent magnet 620 is disposed on the first surface 210 of the cover plate 200, and the other is disposed on the second surface 110 of the base plate 100. Under the condition that the cover plate 200 is fastened on the base 100, the vertical projections of the hall sensor 610 and the second permanent magnet 620 on the second surface 110 are overlapped with each other. The magnetic flux of the second permanent magnet 620 is detected by the hall sensor 610, and when the hall sensor 610 and the second permanent magnet 620 are separated from each other, the distance therebetween increases, and the magnetic flux of the second permanent magnet 620 detected by the hall sensor 610 decreases. At this time, as shown in fig. 31, the hall sensor 610 transmits an electric signal to the control module 700, and the control module 700 supplies power to the electromagnet 531, so that the electromagnet 531 generates magnetism. After the electromagnet 531 generates magnetism, a repulsive force is generated between the electromagnet 531 and the first permanent magnet 512, so that the first permanent magnet 512 drives the second end of the rod body 511 to rotate towards the direction close to the supporting plate 400, that is, the first end of the rod body 511 rotates towards the direction far away from the supporting plate 400, so that the second protrusion 513 is separated from the first protrusion 420, and the plate body 410 slides out of the accommodating groove 130 under the elastic force of the first elastic member 520.

Thus, when the user desires to use the electronic device 01, the user merely turns the cover plate 200 upward to increase the distance between the hall sensor 610 and the second permanent magnet 620. When the hall sensor 610 detects a decrease in the magnetic flux of the second permanent magnet 620, the hall sensor 610 sends a signal to the control module 700, and the control module supplies power to the electromagnet 531 to make the electromagnet 531 generate magnetism. When the electromagnet 531 generates magnetism, the lever body 511 rotates, so that the board body 410 slides out of the receiving groove 130. The user can use the apparatus more conveniently without manually controlling the supporting plate 400.

After a set time (for example, 2s) has elapsed, the control module 700 stops supplying power to the electromagnet 531. The electromagnet 531 can be reset under the action of the second elastic member 540 after being powered off. After the user finishes using, directly push the plate body 410 into the accommodating groove, so that the second protrusion 513 and the first protrusion 420 are mutually clamped, and the plate body 410 is fixed in the accommodating groove 130. The operation is simple and convenient, and better user experience is provided.

In addition, as shown in fig. 32, the plate body 410 includes a first portion 411 and a second portion 412, the second portion 412 can slide out of the receiving groove 130, and the first protrusion 420 is disposed on the first portion 411. To ensure that the plate body 410 does not shake when extending out of the receiving groove 130 to form a support. As shown in fig. 33 and 34, the supporting plate 400 further includes a supporting beam 430, and the supporting beam 430 is disposed on the surface of the plate body 410 away from the second surface 110 and disposed on the second portion 412. The bottom surface of the support beam 430 is flush with the bottom surface of the base 110. When the plate body 410 extends out of the receiving groove 130, a height difference exists between the bottom surface of the plate body 410 and the bottom surface of the base 100, that is, a gap exists between the plate body 410 and a carrying surface (e.g., a table top). Therefore, the supporting beam 430 is disposed on the bottom surface of the board body 410, and the gap between the board body 410 and the carrying surface is filled by the supporting beam 430, so that the board body 410 is prevented from shaking during supporting, and the supporting stability of the keyboard support 10 is ensured.

In addition, as shown in fig. 33 and 34, the supporting beam 430 is disposed in the middle of the second portion 412 along the X direction, and a gap between the supporting beam 430 and the carrying surface on the second portion 412, which is far away from the first portion 411, is not supported, which may cause the electronic device 01 to shake during use. Therefore, in order to further improve the supporting stability of the keyboard support 10, as shown in fig. 35 and 36, the supporting beam 430 provided by the present application is disposed at the edge of the second portion 412 of the plate body 410 away from the first portion 411. With supporting beam 430 set up in the border department of second part 412, can avoid board body 410 to stretch out holding tank 130 after, along the X direction to the rear side slope to avoid whole production to rock, be favorable to improving electronic equipment 01's support stability.

In order to avoid the support beam 430 being exposed outside the receiving groove 130 when the plate body 410 is retracted, as shown in fig. 37, a groove 151 is disposed on an edge of the notch of the receiving groove 130 away from the second surface 110, as shown in fig. 38, the groove 151 is used for receiving the support beam 430. Since the bottom surface of the support beam 430 is flush with the bottom surface of the base 100, when the plate body 410 is retracted into the receiving groove 130, the support beam 430 abuts against the lower edge of the slot of the receiving groove 130. Therefore, the groove 151 is formed at the lower edge of the notch of the accommodating groove 130, when the plate body 410 is retracted into the accommodating groove 130, the supporting beam 430 can be positioned in the groove 151, so that the edge of the plate body 410 and the supporting beam 430 are prevented from being exposed outside the accommodating groove 130, and the overall appearance is facilitated.

In addition, in order to facilitate repair or replacement of components in the receiving groove 130, as shown in fig. 39, the base 100 provided in the present application includes a front case 140 and a rear case 150. The receiving groove 130 is opened on the bottom surface of the front case 140. The rear case 150 is disposed on the bottom surface of the front case 140, and the groove 151 is opened on the edge of the rear case 150. Thus, only the rear shell 150 needs to be removed, and all the components in the receiving groove 130 can be exposed, so that the components in the receiving groove 130 can be maintained or replaced conveniently.

In some embodiments, the front shell 140 and the rear shell 150 may be detachably connected to each other, so as to facilitate detachment, which is beneficial to reduce the difficulty of maintaining the electronic device 01, for example, the front shell may be fixed by a fastener such as a screw. A snap structure may be disposed between the front case 140 and the rear case 150 for snap-fastening. Therefore, the present application does not specifically limit the connection manner between the front case 140 and the rear case 150.

On this basis, as shown in fig. 39, the driving assemblies 500 may be arranged in two groups and symmetrically arranged along a central line of the plate body 410, wherein the central line of the plate body 410 is parallel to the second surface 110 and perpendicular to the third surface 120. The two sides of the plate body 410 are respectively provided with a group of driving assemblies 500, and when the plate body 410 slides, the whole body keeps balance, so that the plate body 410 can smoothly slide out or into the accommodating groove 130.

Example two

In this example, as shown in fig. 40, the present application provides a drive assembly 500 including a screw 560, a holder 570, a drive 580, and a nut 590. The screw 560 is disposed in the receiving groove 130, and the screw 560 is disposed at one side of the supporting plate 400 along a direction parallel to the second surface 110 and parallel to the third surface 120, and the screw 560 is parallel to a sliding direction of the supporting plate 400. The fixing seat 570 is disposed in the receiving groove 130, and one end of the screw 560 is rotatably connected to the fixing seat 570. The driving device 580 is disposed in the receiving groove 130 and electrically connected to the control module 700, and an output shaft of the driving device 580 is fixedly connected to the other end of the screw 560. The nut 590 is sleeved on the screw 560, and the nut 590 is fixedly connected with the support plate 400.

Based on this, as shown in fig. 41, when the sensing assembly 600 sends a signal to the control module 700, the control module 700 controls the driving device 580 to rotate, and the screw rod 560 rotates along with the driving device 580, so that the nut 590 moves along the length direction of the screw rod 560. As shown in fig. 42, since the nut 590 is fixedly coupled to the support plate 400, the support plate 400 can be moved together with the nut 590. Since the screw 560 is parallel to the sliding direction of the supporting plate 400, the nut 590 can drive the supporting plate 400 to slide out of the receiving groove 130, as shown in fig. 43. When the driving device 580 is rotated reversely, the nut 590 is moved in the opposite direction, thereby driving the supporting plate 400 to slide into the receiving groove 130. Thus, the support plate 400 can be driven to slide out of the receiving groove 130 or slide into the receiving groove 130 only by controlling the driving device 580 to rotate. The structure is simpler, and the use is more convenient.

It should be noted that, after the user finishes using the portable electronic device, the user fastens the cover plate 200 on the base, and the hall sensor 610 can detect the magnetic flux of the second permanent magnet 620, or the magnetic flux of the second permanent magnet 620 detected by the hall sensor 610 is the same as the preset value. At this time, the hall sensor 610 sends a signal to the control module 700, and the control module 700 controls the driving device 580 to rotate in the opposite direction, so that the supporting plate 400 slides into the receiving groove 130. Therefore, the supporting plate 400 does not need to be manually pushed into the accommodating groove by a user, and the use is more convenient.

In addition, as shown in fig. 44, the supporting plate 400 includes a plate body 410 and a protrusion 440, and the protrusion 440 is disposed on a sidewall of the plate body 410 close to the screw 560 and connected with the plate body 410 to form an integral structure. The nut 590 is secured to the face of the tab 440 remote from the plate body 410. Since the projection 440 is provided between the plate body 410 and the nut 590, a distance between the plate body 410 and the screw 560 is increased. Thus, the distance between the fixing seat 570 and the plate body 410 is increased, so that the fixing seat 570 and the plate body 410 can be prevented from contacting with each other in the sliding process of the plate body 410, friction is increased, and the plate body 410 can smoothly slide out of the accommodating groove 130 or slide into the accommodating groove 130.

In some embodiments, the driving device 580 is an electric motor or a motor. Since the motor or the motor is a common driving component, the motor or the motor is adopted as the driving device 580, and the difficulty of maintenance and replacement is low in the case of a fault and the maintenance or replacement is needed.

On this basis, the structure of the sensing assembly 600, the structure of the base 100, the number and distribution of the driving assemblies 500, and the like in this example are the same as those in the first example, and therefore, the description will not be repeated.

In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
