[0031] See also Figures 1 to 4The embodiment of the present application provides a storage tool, which includes: a base 100, which is configured as a rectangular frame and is provided with weight-reducing holes; a bracket 200, which is arranged on the base 100; a clamping assembly 300, which is rotatably arranged at one end of the bracket 200 away from the base 100, and the clamping assembly 300 includes two clamping arms 310, and the two clamping arms 310 are arranged at intervals along the length direction Y of the base 100 and enclosed to form a storage space; and a limiting assembly 400, which is arranged on the bracket 200 and is located on the outside of the two clamping arms 310, and the limiting assembly 400 is used to limit the rotation angle of the clamping assembly 300.

[0032] In this embodiment, compared with the traditional operation method of placing the brake caliper / brake disc 10 scattered on the workshop workstation, the technical solution of this application proposes a storage tool, which can clamp the brake caliper / brake disc 10 and accommodate it in the storage space of the clamping assembly 300, so as to collect and cache the scattered brake caliper / brake disc 10. In this way, when reinstalling the parts, it is convenient for the operators to pick up the parts from the storage tool, thereby improving the efficiency of disassembly and assembly; at the same time, the space advantage of the storage tool is effectively utilized, which greatly reduces the occupied area of ​​the cached brake caliper / brake disc 10 and improves the space utilization rate of the disassembly and assembly workshop. In addition, the centralized storage and management of the brake caliper / brake disc 10 can effectively prevent the operators from tripping and improve the safety of the operation.

[0033] Specifically, the storage tooling is configured as a combination component including at least a base 100, a bracket 200, a clamping assembly 300 and a limit assembly 400. The base 100 may be a rectangular frame with weight-reducing holes provided thereon to reduce the overall weight of the storage tooling and facilitate subsequent transfer. The bracket 200 may include four support columns, which are distributed at rectangular intervals; the bracket 200 may be connected to the base 100 by welding or clamping to improve the connection tightness between the bracket 200 and the base 100; the bracket 200 may be vertically arranged on the base 100 to provide the clamping assembly 300 with assembly space and accommodation space along the height direction Z of the base 100. The clamping assembly 300 includes two clamping arms 310, which are rotatably mounted at the top positions of two support columns on the width direction X of the base 100; the clamping arms 310 can rotate around the straight line on the width direction X of the base 100, and the limiting assembly 400 is used to limit the clamping arms 310 from continuing to rotate downward or continue to flip outward. When the brake caliper / brake disc 10 is placed in the receiving space, the clamping arms 310 rotate toward the base 100 and are limited by the limiting assembly 400 at the lower limit position, thereby clamping and fixing the brake caliper / brake disc 10; when the brake caliper / brake disc 10 is removed, the clamping arms 310 rotate toward the direction away from the base 100 and are limited by the limiting assembly 400 at the upper limit position, thereby restoring the position of the clamping arms 310. The storage tooling provided in this example has a simple structure, a compact layout, a strong space utilization rate, and a small occupied area, which is conducive to a miniaturized layout.

[0034] In a possible embodiment, the clamp arm 310 includes a rotating shaft 311, two supporting members 312 and two elastic members 313. The rotating shaft 311 extends along the width direction X of the base 100 and is mounted on an end of the bracket 200 away from the base 100. A supporting member 312 is rotatably set on the rotating shaft 311 through an elastic member 313. The two supporting members 312 are spaced apart along the width direction X of the base 100, and the two elastic members 313 are located on the outside of the two supporting members 312.

[0035] In this embodiment, the specific configuration of the clamp arm 310 is optimized. Specifically, the clamp arm 310 is configured as a composite component including at least a rotating shaft 311, two supporting members 312 and two elastic members 313. The rotating shaft 311 can be a cylindrical torsion spring shaft, and its two ends are respectively plugged or welded to the positions near the top of the two supporting columns in the width direction X of the base 100. The supporting member 312 can be a plate-like structure, which is rotatably arranged on the rotating shaft 311 and can rotate around the rotating shaft 311; at the same time, the supporting member 312 is limited by the limiting assembly 400 and can only rotate within a certain rotation angle range to prevent the supporting member 312 from overturning and affecting the use. The elastic member 313 can be a torsion spring sleeved on the rotating shaft 311, one end of which is connected to the corresponding supporting column, and the other end is connected to the corresponding supporting member 312. In this way, when the supporting member 312 rotates, it will twist on the elastic member 313 to form a torsion force, and the torsion force can restore the supporting member 312 to its original position when there is no heavy object pressing, so as to facilitate subsequent use. The clamp arm 310 provided in this example has strong connection stability and reliability, has a strong clamping force on the brake caliper / brake disc 10, and has good clamping and fixing effects.

[0036] In a possible embodiment, the support member 312 includes a first support plate 3121, a second support plate 3122 and an adapter 3123, the adapter 3123 is movably sleeved on the outside of the rotating shaft 311, the first support plate 3121 and the second support plate 3122 are vertically connected through the adapter 3123, and the second support plate 3122 is arranged toward the base 100.

In this way, the bottom of the brake caliper / brake disc 10 can be placed on the two second support plates 3122 of the clamp arm 310, and the middle protrusion of the brake caliper / brake disc 10 can be embedded between the two first support plates 3121 of the clamp arm 310, so as to support and fix the brake caliper / brake disc 10, and limit the brake caliper / brake disc 10 at least in the width direction X of the base 100, thereby improving the storage stability and reliability of the brake caliper / brake disc 10. The support member 312 provided in this example has a simple structure, is easy to process, and has a low production cost.

[0038] In one example, for the convenience of processing, the first support plate 3121, the second support plate 3122 and the adapter 3123 can be integrally formed, so that the consistency and rigidity of the support member 312 can be improved, and the service life of the support member 312 can be extended.

Specifically, the clamp arm 310 is configured as a composite component including at least a rotating shaft 311, two supporting members 312, two elastic members 313 and a stopper 320. The stopper 320 can be an L-shaped metal component, which is arranged on the edge of the second supporting plate 3122 away from the other second supporting plate 3122 of the same clamp arm 310; the stoppers 320 on the two second supporting plates 3122 of the same clamp arm 310 are arranged opposite to each other, so as to facilitate limiting the position of the front and rear sides of the brake caliper / brake disc 10 in the width direction X of the base 100, and further improve the storage stability and reliability of the brake caliper / brake disc 10. The clamp arm 310 provided in this example has high clamping stability and good clamping effect on the brake caliper / brake disc 10.

[0042] In this embodiment, the specific configuration of the stopper 320 is optimized. Specifically, the stopper 320 is configured as a combined component including at least a connecting portion 321 and a limiting portion 322. The connecting portion 321 can be a plate-like structure, which can be connected to the second support plate 3122 by fasteners such as screws / bolts, or can be connected to the second support plate 3122 by welding or bonding, so as to improve the connection tightness between the stopper 320 and the second support plate 3122; the limiting portion 322 can be a plate-like structure, which can be vertically connected to the connecting portion 321 and protrude toward the first support plate 3121 to stop the brake caliper / brake disc 10 in a direction perpendicular to the second support plate 3122, thereby limiting the movement of the brake caliper / brake disc 10 in the width direction X of the base 100, and improving the storage stability and reliability of the brake caliper / brake disc 10. The stopper 320 provided in this example has a simple structure and is easy to process.

[0043] In a possible embodiment, the limiting component 400 includes a first limiting member 410 and a second limiting member 420. The first limiting member 410 is disposed at one end of the bracket 200 away from the base 100 and is located above the rotating shaft 311, and is used to limit the support member 312 from flipping outward; the second limiting member 420 is disposed at one end of the bracket 200 close to the base 100 and is located below the support member 312, and is used to limit the support member 312 from flipping downward.

[0044] In this embodiment, the specific configuration of the limit assembly 400 is optimized. Specifically, the limit assembly 400 is configured as a combined component including at least a first limit member 410 and a second limit member 420. The first limit member 410 can be a strip-shaped narrow plate, which can be set up at the top position of the two support columns in the width direction X of the base 100, and is used to stop the support member 312 from continuing to flip outward to prevent the support member 312 from over-flipping; the second limit member 420 can be a nearly tic-tac-toe beam structure, which is set up on one end of the bracket 200 close to the base 100, and the second limit member 420 is spaced from the base 100, and is used to stop the support member 312 from continuing to rotate downward to prevent the support member 312 from colliding with the base 100 and being damaged. The limit assembly 400 provided in this example has a simple structure, stable connection, and excellent limiting effect.

[0045] In a possible embodiment, the second limiting member 420 includes two connecting beams 421 and two stopping beams 422, the connecting beams 421 extend along the width direction X of the base 100 and are mounted on one end of the bracket 200 close to the base 100, and the two connecting beams 421 are distributed at intervals in the length direction Y of the base 100; the stopping beams 422 extend along the length direction Y of the base 100 and are mounted on the two connecting beams 421 corresponding to the support members 312, and the two stopping beams 422 are distributed at intervals in the width direction X of the base 100.
