However, in existing interchangeable battery clamping equipment, after adjusting the clamping distance, manual intervention with auxiliary mechanisms such as lead screws is usually required to fix the actual clamping position of the clamping bars. On the one hand, this operation is inefficient, labor-intensive, and time-consuming, seriously affecting the overall production efficiency of the production line. On the other hand, lead screw-type auxiliary mechanisms also greatly increase the production cost of related equipment. Summary of the Invention

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0026] Example 1

[0027] This invention provides a self-locking clamp, comprising a support plate 100; a bearing assembly 200, the bearing assembly 200 including a mounting plate 240 connected to the support plate 100 and movable vertically above the support plate 100; and a self-locking assembly 300 including a guide member 310, a sliding member 320, and a fixing member 330, wherein the guide member 310 is connected to one side of the mounting plate 240, and the guide member 310 includes a limiting groove 312 and a guide slope 313. 3. An inclined mounting plate 240 is inclined along its length, and a limiting groove 312 is connected to one end of a guide slope 313. A sliding member 320 is mounted on a support plate 100 and includes a sliding wheel 321 and a first locking member 323 connected to each other. The sliding wheel 321 moves in contact with the guide slope 313. A fixing member 330 is mounted on the support plate 100 and includes a second locking member 332. When the sliding wheel 321 moves into the limiting groove 312, the first locking member 323 and the second locking member 332 lock each other.

[0028] For ease of description, in this embodiment, the length direction of the mounting plate 240 is defined as the first direction X, the width direction of the mounting plate 240 is defined as the second direction Y, and the height direction of the mounting plate 240 is defined as the third direction Z, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0029] The self-locking fixture of the present invention achieves self-locking positioning of the fixture through the cooperation between the bearing component 200 and the self-locking component 300. Compared with the conventional locking method using manual and lead screws in the industry at present, on the one hand, the self-locking mechanism of this application has the advantages of simple structure and stable effect. It can quickly self-lock after moving and positioning, which greatly reduces the changeover time and improves the overall processing efficiency. On the other hand, the production cost of this application is low and the application range is wide. Therefore, the self-locking fixture described in this embodiment has a broader application prospect and significant advantages.

[0030] See Figure 1 and Figure 2 As shown, in this embodiment, the support plate 100 extends along the first direction X and its upper surface is horizontally arranged. The support plate 100 is preferably a flat plate with a certain width on its upper surface. The self-locking component 300 and the bearing component 200 are arranged along the width direction of the support plate 100 and are both installed on the upper surface of the support plate 100. Furthermore, the self-locking component 300 is connected to the middle section of the support plate 100 and the bearing component 200 is connected to both ends of the support plate 100, thereby realizing a stable connection structure between the above three components, and thus achieving mutual cooperation during use through reasonable layout.

[0031] See Figure 1 and Figure 2As shown, the supporting component 200 also includes at least one lifting module 220, and the mounting plate 240 is connected to the support plate 100 through the lifting module 220. In this embodiment, two lifting modules 220 are symmetrically arranged at both ends of the mounting plate 240 along its length. Each lifting module 220 includes a longitudinal slide rail 222 and a driver 221. The driver 221 is connected to the mounting plate 240, thereby driving the mounting plate 240 to move along the longitudinal slide rail 222. Further, the driver 221 is preferably a cylinder. In other embodiments, the driver 221 can also be set as a motor or other components with driving functions. Correspondingly, in other embodiments, different numbers of lifting modules 220 can be set according to factors such as the length and weight of the mounting plate 240, or the lifting modules 220 can be connected to other positions. This invention does not specifically limit this. In this embodiment, a baffle 224 is also provided around the lifting module 220 to protect the components in the lifting module 220 and reduce the possibility of damage caused by contamination or external impact. In this embodiment, two buffers 223 are provided between the two lifting modules 220. Further, the buffer 223 is preferably a compression spring, which is used to buffer and limit the lifting and moving of the mounting plate 240 to avoid impact damage between it and the support plate 100 due to excessive motion inertia. Similarly, the buffer 223 can also be a buffer sponge, elastic rubber or other elements with buffering function. The present invention does not limit the material, number or connection position of the buffer 223.

[0032] See Figure 1 and Figure 3 As shown, the mounting plate 240 has a mounting groove 230 on one side facing the self-locking assembly 300, and a receiving groove 210 on the opposite side. The guide member 310 is connected to the mounting groove 230, and the pressure strip 400 is supported in the receiving groove 210. In this embodiment, the mounting groove 230 and the receiving groove 210 are provided on both sides along the width direction of the mounting plate 240. The mounting groove 230 is used to connect the guide member 310 and is located in the middle of the mounting plate 240, thereby ensuring that the sliding member 320 and the guide member 310 do not obstruct each other in the second direction Y, thus realizing the smooth movement of the sliding member 320. The receiving groove 210 is on the other side of the mounting plate 240, recessed downward from the upper surface of the mounting plate 240. The extending direction of the receiving groove 210 is the same as that of the mounting plate 240. In use, the pressure strip 400 is placed in the receiving groove 210 and moves synchronously with the mounting plate 240.

[0033] See Figure 3 and Figure 4As shown, in this embodiment, the sliding member 320 and the fixing member 330 are spaced apart on the support plate 100 along the first direction X, and the sliding member 320 and the guide member 310 are arranged along the second direction Y. The guide member 310 is connected to the mounting plate 240. In this embodiment, the sliding member 320 and the fixing member 330 can cooperate with each other to achieve a self-locking function. The guide member 310 provides a sliding trajectory for the sliding member 320, enabling it to move closer to or further away from the fixing member 330.

[0034] Specifically, the slider 320 further includes a transverse module 324, which is arranged along the length of the mounting plate 240. The first locking member 323 is connected to the support plate 100 through the transverse module 324 and moves along the transverse module 324. In this embodiment, the transverse module 324 includes a slider 3241 and a transverse slide rail 3242. The transverse slide rail 3242 extends along the first direction X and is fixedly connected to the functional surface of the support plate 100. The slider 3241 is slidably disposed on the transverse slide rail 3242 and can slide along the transverse slide rail. Further, the slider 320 also includes a first connecting block 322 connected to the slider 3241. The first locking member 323 and the sliding wheel 321 are both connected to the slider 324 through the first connecting block 322. 1. And move synchronously with the slider 3241 along the transverse module 324. Further, in this embodiment, the first connecting block 322 is preferably an inverted "T" shaped element, the height of its upper surface is not lower than the upper surface of the guide member 310, and the sliding wheel 321 is disposed on the side of the first connecting block 322 facing the guide member 310. It passes through the first connecting block 322 through the connecting shaft and rotates around the axis of the connecting shaft, thereby minimizing the contact friction between it and the guide member 310 and improving the flexibility of the use of this fixture.

[0035] The first locking member 323 is disposed on the surface of the first connecting block 322 facing the fixing member 330. The first locking member 323 includes a first connecting portion 3231, an extension portion 3232, and a first locking portion 3233. The first connecting portion 3231 is connected to the first connecting block 322. The extension portion 3232 extends along the length direction of the mounting plate 240, with one end connected to the first connecting portion 3231 and the other end connected to the first locking portion 3233. The first locking portion 3233 extends perpendicularly to the extension portion 3232 toward the mounting plate 240. In this embodiment, the first connecting portion 3231, the extension portion 3232, and the first locking portion 3233 are fixedly connected and are essentially integrally formed. The three together enclose a connection space through which the second locking member 332 can pass.

[0036] See Figure 3As shown, the fixing member 330 also includes a second connecting block 331 and a reset rod 333. The second connecting block 331 has a connecting groove 3311 inside. The second locking member 332 is rotatably disposed inside the connecting groove 3311. The reset rod 333 is disposed along the height direction of the mounting plate 240, with one end connected to the second locking member 332 and the other end connected to the second connecting block 331. In this embodiment, the second locking member 332 is connected to the support plate 100 through the second connecting block 331. Further, the second connecting block 331 has a connecting groove 3311 for connecting the second locking member 332 and a connecting platform 3312 for the reset rod 333 to pass through and connect. In this embodiment, the connecting groove 3311 and the connecting platform 3312 are arranged sequentially along the first direction X. The connecting platform 3312 is disposed above the end of the transverse slide rail 3242 in the third direction Z. In this embodiment, the second locking member 332 cooperates with the first locking member 323 to realize the self-locking function of the fixture. Specifically, the second locking member 332 includes a second connecting part 3321 and a second locking part 3322. The second connecting part 3321 is rotatably connected to the second connecting block 331, and the second locking part 3322 is fixed to the free end of the second connecting part 3321 and extends toward the mounting plate 240. In this embodiment, one end of the second connecting part 3321 is provided with a rotating shaft, which can pass through the connecting groove 3311 and rotate around its axis. The second locking part 3322 is integrally formed with the second connecting part 3321, rotates synchronously with the second connecting part 3321, and can be inserted into the connecting space. At the same time, the second locking part 3322 and the first locking part 3233 can mutually limit each other in the first direction X to form a stable structure after self-locking. Furthermore, in this embodiment, a handle 3323 is provided on the side of the second locking member 332 away from the mounting plate 240. The operator can control the second locking member 332 to rotate through the handle 3323 to control the locking state or unlocking state of the self-locking component 300.

[0037] In this embodiment, the reset rod 333 is preferably a columnar element with compressive elasticity, extending in the third direction Z and connecting between the second locking member 332 and the connecting platform 3312. The reset rod 333 is used to maintain the initial height of the second locking member 332 when no external force is applied, and can provide a thrust to the second locking member 332 as it passes through the connecting space. Correspondingly, in other embodiments, the reset rod 333 can be set as a telescopic rod, elastic rubber, or other element with an automatic reset function, and the present invention does not limit this.

[0038] See Figure 5As shown, the guide slope 313 gradually extends upward towards the side facing the fixing member 330, and the limiting groove 312 is recessed downward from the top of the guide slope 313. Furthermore, the guide member 310 also includes two stop portions 311 respectively disposed at both ends of the limiting groove 312 and the guide slope 313. The stop portions 311 protrude from the upper surface of the limiting groove 312 and the guide slope 313 along the height direction of the mounting plate 240. In this embodiment, the limiting groove 312 is disposed at one end of the guide member 310 along the first direction X, and the guide slope 313 extends downward from the guide groove toward the other end. Two stop portions 311 are provided at both ends of the guide member 310. Any stop portion 311 is disposed from the bottom surface of the guide member 310 along the third direction Z. The guide slope 313 and the limiting groove 312 are disposed sequentially between the two stop portions 311. When the mounting plate 240 rises along the third direction Z, the sliding wheel 321 can move along its surface toward the limiting groove 312 under the guidance of the guide slope 313 until the sliding member 320 moves into the interior of the limiting groove 312 and stops. In this embodiment, since the bottom of the limiting groove 312 is lower than the top of the guide slope 313, under the cooperation of the limiting groove 312 and the stop portion 311, the sliding wheel 321 can drive the first locking member 323 to engage with the second locking member 332 and form a stable mutual locking structure with the second locking member 332.

[0039] The following describes the usage process and principle of the self-locking clamp in this embodiment:

[0040] When in use, the lifting module 220 will drive the mounting plate 240 and the guide member 310 on it to move upward synchronously. At this time, the sliding wheel 321 located at the bottom of the guide slope 313 will move along the first direction X under the guidance of the guide slope 313 and gradually approach the fixing member 330 until it is stably restricted in the limiting groove 312. During the above process, the second locking part 3322 can be engaged in the connecting space and form a stable locking relationship with the first locking part 3233 in the first direction X, thereby realizing the self-locking function of this fixture.

[0041] When it is necessary to unlock, the operator only needs to rotate the second locking part 332 clockwise by the handle 3323 to disengage the second locking part 3322 from the connection space. After that, each component will automatically reset under the action of gravity or thrust, waiting for the next self-locking process, thus completing a complete work step.

[0042] In summary, the self-locking fixture achieves self-locking positioning through the cooperation between the bearing component 200 and the self-locking component 300. Compared with the conventional locking method using manual operation and lead screws in the industry at present, the self-locking mechanism in this application has advantages such as simple structure and stable effect. It can quickly self-lock after moving and positioning, which greatly reduces changeover time and improves the overall processing efficiency. On the other hand, the production cost of this application is low and the application range is wide. Therefore, the self-locking fixture described in this embodiment has a broader application prospect and significant advantages.

Furthermore, each pair of adjacent self-locking clamps is equipped with a pressure bar 400, and the clamps move relatively closer or further apart, thereby clamping or releasing the battery between them.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
