Referring to fig. 1 to 12, an embodiment of the present invention provides a storage cabinet, which includes a cabinet 100, a storage assembly 200, an access mechanism 300 and a lifting mechanism 400; the cabinet body 100 is provided with a storage space, the storage assembly 200 is arranged in the storage space, the storage assembly 200 comprises a base 210 and an object 220, and the object 220 is movably arranged on the base 210; the access mechanism 300 is arranged on at least one side of the base 210, and the access mechanism 300 is respectively connected with the base 210 and the cabinet 100 and used for driving the base 210 to switch between a hidden position of returning to the storage space and a drawn-out position of extending out of the storage space; the lifting mechanism 400 is arranged on at least one side of the object 220, and the lifting mechanism 400 comprises a pulley assembly, a lifting flexible cable 410 and a lifting driving member 420; the flexible lifting cable 410 is wound on the pulley assembly to form a plurality of installation positions 401 which move synchronously and in the same direction on the flexible lifting cable 410 and/or the pulley assembly, and the object placing element 220 is installed on the installation positions 401; the lifting driving member 420 is fixed to the base 210, and is used for driving the lifting flexible cable 410 to drive the object 220 to move up and down relative to the cabinet 100. Wherein the storage cabinet may be, but is not limited to, a refrigerator, a retail cabinet, or a sterilizer.

For example, as shown in fig. 1, the base 210 is a drawer located at the lower portion of the french refrigerator, and the storage object 220 is a storage box in the drawer. When it is desired to take or place an item from the article placing element 220, as shown in fig. 2, a user may first activate the access mechanism 300 to slide the base 210 relative to the cabinet 100 toward the user until reaching the extracted position; next, as shown in fig. 1, the lifting driving member 420 is started to drive the lifting flexible cable 410 to drive the object 220 to rise smoothly until the object 220 extends out of the base 210; after the article is taken or placed, the lifting driving member 420 is restarted to drive the lifting flexible cable 410 to drive the placing object 220 to descend stably until the placing object 220 falls into the base 210 again; finally, the access mechanism 300 is again actuated to slide the base 210 relative to the cabinet 100 away from the user until the concealed position is reached. In order to improve the aesthetic appearance and reduce the risk of the pulley assembly being caught by foreign objects, as shown in fig. 4, a cavity is formed in the sidewall of the base 210, the lifting mechanism 400 is disposed in the cavity of the base 210, and elongated holes corresponding to the mounting locations 401 are formed in one-to-one correspondence on the side of the sidewall of the base 210 facing the object 220, and the elongated holes extend along the height direction of the base 210.

As can be seen from the above, in the storage cabinet of the embodiment, the lifting mechanism 400 and the access mechanism 300 are disposed on at least one side of the storage component 200, when taking or placing an article, the access mechanism 300 is activated to drive the base 210 to extend out or retract into the cabinet 100, i.e. to approach or leave away from the user, and on this basis, the lifting mechanism 400 is activated to lift or fall the storage component 220 relative to the base 210, thereby preventing the user from bending down to take and place the article, and improving the user experience. In addition, since the lifting flexible cable 410 and the pulley assembly of the lifting mechanism 400 are used to lift the article 220, the single-side multi-point lifting of the article 220 can be realized by the pulley assembly, and the vibration generated by the lifting driving member 420 can be absorbed by the flexibility of the lifting flexible cable 410, so that the vibration generated by the lifting driving member 420 is prevented from being transmitted to the article 220, and the stable lifting of the article 220 is realized. In addition, since the assembly floor space of the pulley assembly is small, the lifting mechanism 400 has little influence on the volume ratio of the cabinet.

As shown in fig. 5 to 9, the pulley assembly includes a plurality of fixed pulleys rotatably disposed on the base 210, the lifting flexible cable 410 forms a plurality of parallel cable segments with the same transmission direction between the fixed pulleys, and the installation site 401 is disposed on the cable segments. When the flexible lifting rope 410 is annular, the plurality of fixed pulleys comprise a plurality of first fixed pulleys 431, a plurality of second fixed pulleys 432 and at least one third fixed pulley 433 arranged between two adjacent second fixed pulleys 432, that is, the pulley assembly is a fixed pulley group which comprises a first fixed pulley group, a second fixed pulley group and a third fixed pulley group, and the second fixed pulley group is arranged below the first fixed pulley group and is in transmission connection with the first fixed pulley group through the flexible lifting rope 410; the third fixed pulley group is arranged between the first fixed pulley group and the second fixed pulley group; the lifting flexible cable 410 wound between two adjacent second fixed pulleys 432 is wound around a corresponding third fixed pulley 433, so that the lifting flexible cable 410 forms a plurality of flexible cable sections between the first fixed pulley block and the second fixed pulley block; the elevation driving member 420 is connected to the first fixed pulley 431, the second fixed pulley 432, or the third fixed pulley 433. The lifting/lowering drive 420 may be, but is not limited to, a motor or a rotating handle.

The operation principle of the lifting mechanism 400 in the embodiment of the present invention will be described below by taking two mounting locations 401, that is, the pulley assembly includes two first fixed pulleys 431, two second fixed pulleys 432 and one third fixed pulley 433 as an example:

as shown in fig. 5 and 6, the first fixed pulley 431, the third fixed pulley 433 and the second fixed pulley 432 are sequentially disposed from top to bottom, the third fixed pulley 433 is disposed adjacent to the first fixed pulley 431, and the left first fixed pulley 431, the left second fixed pulley 432, the third fixed pulley 433, the right second fixed pulley 432 and the right first fixed pulley 431 are sequentially connected by the flexible lifting cable 410 in a transmission manner. The transmission directions of the flexible lifting wire 410 wound between the third fixed pulley 433 and one of the second fixed pulleys 432 and the flexible lifting wire 410 wound between the other second fixed pulley 432 and the corresponding first fixed pulley 431 are the same and parallel.

As shown in fig. 6, the halyard 410 wound around the second fixed pulley 432 on the right and the first fixed pulley 431 on the right and the halyard 410 wound around the third fixed pulley 433 and the second fixed pulley 432 on the left are parallel to each other and have the same transmission direction, and can be formed as two wire segments. Since the two wire sections extend in the vertical direction, the object 220 can be lifted and lowered in the vertical direction after the sidewall of the object 220 is fixed to the two wire sections by the connecting member. Specifically, when the lifting driving member 420 drives the lifting flexible cable 410 to rotate in the counterclockwise direction, the two flexible cable segments, i.e., the lifting flexible cable 410 wound between the third fixed pulley 433 and the left second fixed pulley 432, and the lifting flexible cable 410 wound between the right second fixed pulley 432 and the right first fixed pulley 431, both move upward, and further, the device 220 is driven to move upward vertically. When the lifting driving member 420 drives the lifting flexible cable 410 to move clockwise, both cable sections move downward, and the placing member 220 is driven to move downward vertically.

As shown in fig. 6, the flexible wires 410 wound around the first fixed pulley 431 and the second fixed pulley 432 on the left side and the flexible wires 410 wound around the third fixed pulley 433 and the second fixed pulley 432 on the right side are parallel to each other and have the same transmission direction, and therefore, they may be two flexible wire segments. However, since the two wire segments extend at an angle to the vertical direction, after the sidewall of the placement member 220 is fixed to the two wire segments by the connecting member, the movement track of the placement member 220 is inclined upward or downward.

Of course, in practical applications, the position of the wire segment may be determined according to specific requirements, for example, when the flexible lifting wire 410 wound between the second fixed pulley 432 on the right side and the first fixed pulley 431 on the right side and the flexible lifting wire 410 wound between the third fixed pulley 433 and the second fixed pulley 432 on the left side both extend in the vertical direction, the flexible lifting wire 410 wound between the first fixed pulley 431 on the left side and the second fixed pulley 432 on the left side and the flexible lifting wire 410 wound between the third fixed pulley 433 and the second fixed pulley 432 on the right side may not be parallel, that is, not be a wire segment. At this time, as shown in fig. 5, the elevating mechanism 400 can vertically elevate the placement module 200, but cannot obliquely elevate it.

In addition, in order to reduce the stress of the third fixed pulley 433 or based on the requirement of the actual installation space, a plurality of third fixed pulleys 433 may be disposed between the two second fixed pulleys 432, for example, as shown in fig. 7 to 9, the pulley assembly includes two first fixed pulleys 431, two second fixed pulleys 432, and two third fixed pulleys 433. The first fixed pulley 431, the third fixed pulley 433 and the second fixed pulley 432 are sequentially arranged from top to bottom, the third fixed pulley 433 is arranged close to the first fixed pulley 431, the left second fixed pulley 432, the left third fixed pulley 433, the right second fixed pulley 432 and the right first fixed pulley 431 are sequentially in transmission connection through the lifting flexible cable 410, and the lifting flexible cable 410 is in an inverted concave shape. In this case, the ascent and descent wire 410 wound around the third fixed pulley 433 provided on the left side and the second fixed pulley 432 provided on the left side and the ascent and descent wire 410 wound around the second fixed pulley 432 provided on the right side and the first fixed pulley 431 provided on the right side are parallel to each other and have the same transmission direction, and may be provided as two wire segments. When the lifting driving member 420 drives the lifting flexible cable 410 to rotate in the counterclockwise direction, the two flexible cable segments, i.e., the lifting flexible cable 410 wound between the third fixed pulley 433 on the left side and the second fixed pulley 432 on the left side, and the lifting flexible cable 410 wound between the second fixed pulley 432 on the right side and the first fixed pulley 431 on the right side, move upward, and further drive the placement object 220 to move vertically upward. When the lifting driving member 420 drives the lifting flexible cable 410 to move clockwise, both cable sections move downward, and further the placing member 220 is driven to move downward vertically.

The number of the mounting positions 401 may be two or more than two. For example, the pulley assembly includes two first fixed pulleys 431, three second fixed pulleys 432, and two third fixed pulleys 433. In this case, the flexible wires 410 wound around the third fixed pulley 433 on the left side and the second fixed pulley 432 on the left side, the flexible wires 410 wound around the third fixed pulley 433 on the right side and the second fixed pulley 432 in the middle, and the flexible wires 410 wound around the first fixed pulley 431 on the right side and the second fixed pulley 432 on the right side may be arranged in the same and parallel transmission direction as three flexible wire segments. The two ends and the middle part of the side wall of the base 210 can be fixed on the three flexible cable sections through connecting pieces respectively.

To ensure that the lifter wires 410 remain tensioned, a tensioner 440 is provided on the lifter wires 410 as shown in fig. 5 and 7. The flexible lifting cable 410 may be, but is not limited to, a timing belt or a chain. When the elevator rope 410 is a timing belt, the first fixed pulley 431, the second fixed pulley 432, and the third fixed pulley 433 are all gears engaged with the timing belt. When the flexible lifting cord 410 is a chain, the first fixed pulley 431, the second fixed pulley 432, and the third fixed pulley 433 are chain wheels engaged with the chain. In addition, for the convenience of later replacement and maintenance, the first fixed pulley 431, the second fixed pulley 432 and the third fixed pulley 433 can adopt fixed pulleys of the same specification, that is, the sizes and the materials of the three are the same.

It should be noted that, in order to realize the single-sided multi-point hoisting of the object 220, the flexible lifting cable 410 may be in a shape of a ring or a line. For example, as shown in fig. 10, the flexible lifting cable 410 includes a first flexible cable 411 and a second flexible cable 412, both of which are linear, a pulley assembly includes a first movable pulley 434 and a second movable pulley 435, and the installation site 401 is provided on the first movable pulley 434 and the second movable pulley 435; first ends of the first and

second wires

411 and 412 are fixed to the base 210, a second end of the first wire 411 is wound around the first movable pulley 434 and then wound around the lift driving member 420, and a second end of the second wire 412 is wound around the second movable pulley 435 and then wound around the lift driving member 420. The lifting driving member 420 includes a motor, a driving reel 421 and a driven reel 422 installed on the base 210, a second end of the first flexible cable 411 is wound on the driving reel 421, a second end of the second flexible cable 412 is wound on the driven reel 422, a driving gear 423 is fixed at an end of the driving reel 421, and a driven gear 424 engaged with the driving gear 423 is fixed at an end of the driven reel 422; the motor is connected to the active winding drum 421 for driving the active winding drum 421 to rotate.

Based on the orientation shown in fig. 10, when the motor drives the driving drum 421 to rotate clockwise, the driving gear 423 and the driven gear 424 are continuously engaged, so as to drive the driven drum 422 to rotate counterclockwise synchronously. In the process, the first flexible cable 411 is continuously wound on the driving reel 421, and at the same time, the second flexible cable 412 is continuously wound on the driven reel 422, so as to drive the first movable pulley 434 and the second movable pulley 435 to synchronously move upwards. On the contrary, when the motor drives the driving drum 421 to rotate counterclockwise, the driven drum 422 rotates clockwise synchronously, and the first flexible cable 411 and the second flexible cable 412 are disengaged from the driving drum 421 and the driven drum 422 respectively, so as to drive the first movable pulley 434 and the second movable pulley 435 to move downwards synchronously. Accordingly, the base 210 to which the first movable pulley 434 and the second movable pulley 435 are fixed can be moved up and down.

It should be noted that, in order to realize the synchronous rotation of the driving drum 421 and the driven drum 422, besides the driving gear 423 and the driven gear 424, the synchronous rotation can be realized by increasing the number of motors, that is, two motors are provided. The two motors are respectively connected with the driving winding drum 421 and the driven winding drum 422, and the synchronous rotation of the driving winding drum 421 and the driven winding drum 422 can be realized by accurately controlling the opening and closing time and the rotating speed of the two motors, so that the synchronous and same-direction movement of the first movable pulley 434 and the second movable pulley 435 can be realized.

As shown in fig. 5 and 7, the lifting mechanism 400 is provided on both sides of the base 210, and the two lifting drivers 420 are integrated, that is, one lifting driver 420 is shared by two lifting devices. When the flexible lifting cables 410 are annular and the lifting driving member 420 is a motor, the pulley assemblies of the two lifting devices are connected through the transmission rod 450, the output shaft of the motor is connected with the transmission rod 450, and the motor drives the two flexible lifting cables 410 to transmit through the transmission rod 450. Of course, the lifting mechanism 400 may be provided only on one side of the base 210, and the other side may be provided with a rail extending in the height direction of the cabinet 100; the side of the object 220 opposite to the lifting mechanism 400 is connected with the guide rail in a sliding manner. Specifically, the guide rail is formed with a slide groove extending in a height direction thereof, and a protrusion slidably engaged with the slide groove is formed on a sidewall of the object placing member 220. Of course, the rail may also have a rib extending along the height direction thereof, and the sidewall of the object placing member 220 may have a groove slidably engaged with the rib. Compared with the lifting mechanism 400 arranged on only one side of the base 210, the lifting mechanisms 400 arranged on both sides of the base 210 can realize multipoint hoisting on both sides of the object placing piece 220, improve the stability of the object placing piece 220 in the up-and-down moving process, and reduce the assembly floor area without additionally arranging guide rails.

To switch the base 210 between the concealed position and the extracted position, the access mechanism 300 may take a variety of structural forms, such as:

in the first form, as shown in fig. 11 and 13, the access mechanism 300 includes a first slide rail 310, a second slide rail 320, an access wire 350, an access fixed pulley 341, a rotating wheel 342, and an access driving member; the first slide rail 310 is fixed to the cabinet 100, the second slide rail 320 is fixed to the base 210, and the second slide rail 320 is slidably mounted on the first slide rail 310 and adapted to slide relative to the first slide rail 310; the in-out fixed pulley 341 is rotatably mounted on the first slide rail 310, the rotating wheel 342 is rotatably mounted on the cabinet 100 or the first slide rail 310, the in-out flexible cable 350 is wound around the rotating wheel 342 and the in-out fixed pulley 341, and both ends of the in-out flexible cable 350 are connected to the second slide rail 320; the in-out drive is used to drive the rotation wheel 342.

When the object is to be taken or placed from the object placing member 220, the in-out driving member is activated to drive the rotating wheel 342 to rotate. Because the in-out flexible cable 350 is wound around the rotating wheel 342 and the in-out fixed pulley 341, two ends of the in-out flexible cable 350 are connected to the second sliding rail 320, the first sliding rail 310 is fixed to the cabinet 100, and the second sliding rail 320 is fixed to the base 210, so that the rotating wheel 342 drives the second sliding rail 320 to make a linear motion relative to the first sliding rail 310 through the in-out flexible cable 350 during the rotation process, that is, the base 210 horizontally slides in a direction approaching or moving away from the user relative to the cabinet 100, that is, switches between the hidden position and the extracted position. It should be noted that, in the above process, the rotating wheel 342 only drives the in-out fixed pulley 341 to rotate through the in-out flexible cable 350, and does not drive the in-out fixed pulley 341 to change the spatial position. The number of the in-and-out fixed pulleys 341 may be one or more. For example, as shown in fig. 14, since the diameters of the rotating wheel 342 and the in-out fixed pulley 341 are slightly different, when the in-out fixed pulley 341 is provided at both ends of the first sliding rail 310, the in-out fixed pulley 341 adjacent to the rotating wheel 342, that is, the in-out fixed pulley 341 located at the right side in fig. 14 corresponds to a line passing wheel, and the presence of the in-out fixed pulley 341 can keep the in-out flexible cable 350 between the in-out fixed pulley and the other in-out fixed pulley 341 horizontal. In addition, the rotation direction of the rotation wheel 342 is different, and the moving direction of the second slide rail 320 relative to the first slide rail 310 is different. Based on the orientation shown in fig. 11, when the rotating wheel 342 rotates clockwise, the in-out flexible cable 350 drives the second sliding rail 320 to move rightward relative to the first sliding rail 310; when the rotating wheel 342 rotates counterclockwise, the in-out flexible cable 350 drives the second sliding rail 320 to move leftward relative to the first sliding rail 310. It can be seen that the in-out mechanism 300 of the present embodiment not only has a simple structure and a small space, but also is convenient to assemble and disassemble the in-out mechanism 300 because only the rotating wheel 342, the in-out fixed pulley 341 and the in-out driving member are involved.

As shown in fig. 11, to facilitate fixing the in-out wire 350 to the second slide rail 320, a slider 380 is fixed to the second slide rail 320, and both ends of the in-out wire 350 are fixed to the slider 380. The manner of fixing the slider 380 to the inlet/outlet wire 350 is not limited, and may be, for example, binding, screwing, or welding. In order to ensure the moving stroke of the second slide rail 320 relative to the first slide rail 310, the slider 380 may be disposed at an end of the second slide rail 320 adjacent to the rotating wheel 342. Of course, in addition to the in-out wire 350 being fixed by the slider 380, as shown in fig. 14, the end of the in-out wire 350 may be fixed by a fixing member 390, and the fixing member 390 fixes the in-out wire 350 to the second slide rail 320 by a screw.

In order to realize multi-stage extension and contraction of the in-out mechanism 300 and extend the extension and contraction stroke thereof, as shown in fig. 13, the in-out mechanism 300 further includes at least one intermediate slide rail 330, the first slide rail 310 is slidably connected to the second slide rail 320 through the intermediate slide rail 330, at least one in-out movable pulley 343 is rotatably mounted on the intermediate slide rail 330, and the in-out flexible cable 350 between the in-out fixed pulley 341 and the second slide rail 320 passes around the in-out movable pulley 343. When the number of the middle slide rails 330 is plural, two adjacent middle slide rails 330 are slidably connected to each other, so that the two middle slide rails 330 can slide relative to each other.

For example, as shown in fig. 11, an intermediate slide rail 330 is disposed between the first slide rail 310 and the second slide rail 320, upper and lower edges of the intermediate slide rail 330 are slidably mounted on the first slide rail 310 and the second slide rail 320, for example, a first groove extending along a length direction of the first slide rail 310 is formed on a side of the first slide rail 310 facing the intermediate slide rail 330, a second groove extending along a length direction of the second slide rail 320 is formed on a side of the second slide rail 330 facing the intermediate slide rail 330, and upper and lower edges of the intermediate slide rail 330 are embedded in the second groove and the first groove, respectively. Of course, besides the above-mentioned manner, a first rib extending along the length direction of the first slide rail 310 may be formed on one side of the second slide rail 320 facing the middle slide rail 330, a second rib extending along the length direction of the second slide rail 320 facing the middle slide rail 330, third grooves extending along the length direction of the middle slide rail 330 are formed on both the upper and lower sides of the middle slide rail 330, and the first rib and the second rib are respectively slidably embedded in the corresponding third grooves. The two ends of the middle sliding rail 330 are both rotatably installed with an in-out movable pulley 343, and an in-out flexible cable 350 between the in-out fixed pulley 341 and the second sliding rail 320 firstly passes through the in-out movable pulley 343 far away from the back plate of the cabinet 100, i.e. the right side, and then passes through the in-out movable pulley 343 near the back plate of the cabinet 100, i.e. the left side. In this case, the in-out flexible cable 350 located between the in-out fixed pulley 341 and the second sliding rail 320 includes a first flexible cable section 351, a second flexible cable section 352, and a third flexible cable section 353, the first flexible cable section 351 is located between the in-out fixed pulley 341 and the in-out movable pulley 343 far from the back plate of the cabinet 100, the second flexible cable section 352 is located between the two in-out movable pulleys 343, and the third flexible cable section 353 is located between the in-out movable pulley 343 near the back plate of the cabinet 100 and the second sliding rail 320. The first, second and

third wire segments

351, 352, 353 have an included angle therebetween. Of course, in order to ensure smooth operation of the in-out wire 350 and save power for the in-out driving member, the first wire section 351, the second wire section 352 and the second wire section 352 can be parallel to each other by adjusting the size and/or position of the rotating wheel 342, the in-out fixed pulley 341 and the in-out movable pulley 343.

Because the upper and lower edges of the middle sliding rail 330 are slidably mounted on the first sliding rail 310 and the second sliding rail 320, respectively, and the in-out flexible cable 350 between the in-out fixed pulley 341 and the second sliding rail 320 sequentially passes through the two in-out movable pulleys 343, as shown in fig. 11 and 13, when the rotating wheel 342 rotates counterclockwise, the in-out flexible cable 350 between the rotating wheel 342 and the in-out fixed pulley 341 moves rightward, and further drives the in-out fixed pulley 341 to move counterclockwise; the first flexible cable section 351 moves leftwards, so as to drive the right in-out movable pulley 343 to rotate clockwise; the second flexible cable section 352 moves to the right, and then drives the left in-out movable pulley 343 to move counterclockwise; the third wire section 353 moves leftwards, and then drives the second slide rail 320 to move leftwards. In the process of the second slide rail 320 moving to the left, the in-out wire 350 between the rotating wheel 342 and the second slide rail 320 is lengthened, and the in-out wire 350 between the left in-out movable pulley 343 and the second slide rail 320 is shortened. When the second sliding rail 320 moves to the left to the extreme position, if the rotating wheel 342 continues to rotate counterclockwise, the first flexible cable section 351 moves to the left, and the right in-out movable pulley 343 is driven to move to the left, so that the middle sliding rail 330 moves to the left. In the process of the left movement of the intermediate slide rail 330, the in-out wire 350 between the in-out fixed pulley 341 and the right in-out movable pulley 343 is shortened, and the in-out wire 350 between the rotary wheel 342 and the second slide rail 320 is continuously lengthened.

Similarly, when the rotating wheel 342 rotates clockwise, the in-out wire 350 between the rotating wheel 342 and the second sliding rail 320 moves to the right, and then drives the second sliding rail 320 to move to the right. During the rightward movement of the second slide rail 320, the in-out wire 350 between the rotating wheel 342 and the second slide rail 320 is shortened, and the in-out wire 350 between the left in-out movable pulley 343 and the second slide rail 320 is lengthened. When the second slide rail 320 moves to the extreme position, if the rotating wheel 342 continues to rotate clockwise, the in-out flexible cable 350 between the rotating wheel 342 and the second slide rail 320 continues to move to the right, and the third flexible cable section 353 also moves to the right, and drives the in-out movable pulley 343 to move to the right, so as to drive the middle slide rail 330 to move to the right. In the process of rightward movement of the middle slide rail 330, the in-out flexible cable 350 between the in-out fixed pulley 341 and the right in-out movable pulley 343 becomes longer, and the in-out flexible cable 350 between the rotating wheel 342 and the second slide rail 320 continues to become shorter.

Similarly, in the case that a plurality of intermediate sliding rails 330 are disposed between the first sliding rail 310 and the second sliding rail 320, when the in-out driving member drives the rotating wheel 342 to rotate, the rotating wheel 342 first drives the second sliding rail 320 to make a linear motion through the in-out flexible cable 350; when the second slide rail 320 moves to the extreme position, the rotating wheel 342 drives the middle slide rail 330 adjacent to the second slide rail 320 to move linearly by the in-out flexible cable 350; when the intermediate slide rail 330 moves to the extreme position, the rotating wheel 342 drives another intermediate slide rail 330 adjacent thereto to move linearly through the flexible cable 350, and so on.
