[0034] The embodiment of the present utility model provides a multi-acupoint pressure maintaining device, as Figure 1 - Figure 2 shown, which includes a frame 1, a battery pressure maintaining component 2 and a control component 3. The frame 1 is a stepped structure. The frame 1 is provided with at least two stepped panels 11 along the height direction (Z direction), and a control panel 12 is arranged between two adjacent stepped panels 11; there are multiple battery pressure maintaining components 2, and the multiple battery pressure maintaining components 2 are respectively arranged on multiple stepped panels 11. The battery pressure maintaining component 2 is configured to perform pressure maintaining assembly on the battery; there are multiple control components 3, and the multiple control components 3 are arranged on the control panel 12. The control components 3 are arranged in one-to-one correspondence with the battery pressure maintaining components 2 and are communicatively connected.

[0035] The multi-acupoint pressure maintaining device provided by the present utility model, as Figure 1 and Figure 2 taking the frame 1 with three stepped panels 11 arranged thereon as an example, by providing the frame 1 with a stepped structure of three stepped panels 11, at least three battery pressure maintaining components 2 and at least three control components 3 can be arranged on the frame 1. The control components 3 are used to communicatively connect with the battery pressure maintaining components 2 respectively to control the pressure maintaining operation of the battery pressure maintaining components 2, so as to realize the multi-acupoint operation of the battery pressure maintaining assembly, which is beneficial to improving the production capacity and saving the space for pressure maintaining assembly.

[0036] In some embodiments, the control panel 12 is arranged perpendicular to the stepped panel 11.

[0037] As Figure 2, the control panel 12 is a vertical structure disposed between two stepped panels 11. The stepped panels 11 are arranged horizontally, and the control panel 12 is arranged vertically. The bottom end of the control panel 12 is connected to the trailing edge of the lower stepped panel 11, and the top end of the control panel 12 is connected to the leading edge of the higher stepped panel 11, which is conducive to the arrangement of the control assembly 3 on the control panel 12 and facilitates the control operation.

[0038] In some embodiments, a plurality of battery pressure maintaining assemblies 2 are provided on each stepped panel 11, and the plurality of battery pressure maintaining assemblies 2 are arranged at intervals along the length direction (X direction) of the stepped panel 11; a plurality of control assemblies 3 are provided on each control panel 12, and the plurality of control assemblies 3 are arranged in one-to-one correspondence with the plurality of battery pressure maintaining assemblies 2 and are communicatively connected in one-to-one correspondence.

[0039] As Figure 1 In the illustrated embodiment, six battery pressure maintaining assemblies 2 are arranged at intervals along the length direction (X direction) of each stepped panel 11. Each battery pressure maintaining assembly 2 is used for individually installing a battery. The battery is installed in the battery compartment and sealed with a compartment cover. Glue needs to be applied and pressure maintained between the battery compartment and the compartment cover to ensure reliable fitting and waterproof effect. By setting the one-to-one control operation of the plurality of battery pressure maintaining assemblies 2 and the plurality of control assemblies 3, it is conducive to adjusting the respective pressure maintaining times according to the requirements of the battery, and the pressure maintaining control is more flexible and convenient. The battery pressure maintaining assemblies 2 and the control assemblies 3 are arranged in one-to-one correspondence on the frame 1, as Figure 1 , which is convenient for accurately finding the control assembly 3 corresponding to the battery pressure maintaining assembly 2 for operation control and reducing the misoperation rate.

[0040] In some embodiments, the battery pressure maintaining assembly 2 includes a positioning member 21 and a driving member 22. The positioning member 21 is provided with a positioning groove 211. The top of the positioning groove 211 has a first notch 2111, and the side of the positioning groove 211 facing away from the control panel 12 has a second notch 2112. The battery compartment and the compartment cover to be assembled can be installed in the positioning groove 211 through the first notch 2111; the driving member 22 is arranged at an interval from the positioning member 21, and the output end of the driving member 22 can extend toward the second notch 2112 of the positioning groove 211 to press the compartment cover against the battery compartment and maintain pressure.

[0041] As Figure 3As shown in the figure, the positioning member 21 and the driving member 22 are arranged at intervals along the width direction (Y direction) of the stepped panel 11. The driving member 22 can select a cylinder, an oil cylinder or other linear driving mechanisms according to the pressure required for pressure holding of the battery compartment and the cover, preferably a cylinder. The output rod of the cylinder can directly move linearly towards the positioning member 21 to press the cover against the battery compartment to achieve tight sealing. During the pressure holding process, first, the battery is placed in the battery compartment, and then the periphery of the battery compartment opening is spot-glued. Then, the cover is manually covered; the battery compartment and the cover are integrally placed into the positioning groove 211 through the first notch 2111 at the top. The control assembly 3 is started, and the output end of the driving member 22 extends and moves towards one side of the second notch 2112 to tightly press the cover and the battery compartment and continuously hold the pressure; after reaching the pressure holding time, the output end of the driving member 22 retracts to complete a pressure holding assembly. It can be understood that the function of the positioning groove 211 is to fix the battery compartment and the cover. The bottom of the positioning groove 211 provides support, and the cover is pressed under the interaction between the bottom of the groove and the output end of the driving member 22.

[0042] In some embodiments, limiting structures 212 are provided on the inner walls on both sides of the second notch 2112 of the positioning groove 211. The limiting structures 212 extend from the inner wall of the second notch 2112 towards the direction away from the inner wall, and the battery compartment and the cover can be clamped between the bottom of the positioning groove 211 and the limiting structures 212.

[0043] For another example Figure 3 , the limiting structures 212 are arranged on both sides of the second notch 2112 along the length direction of the stepped panel 11 and extend relatively. When the battery compartment and the cover combination are pasted and placed into the positioning groove 211, the limiting structures 212 can limit the cover to prevent it from separating due to the firmness of the pasted part. However, the limiting structures 212 should not affect the cover from receiving a sufficient pressing surface. Therefore, the height of the limiting structures 212 protruding from the inner wall of the second notch 2112 is small, and it can overlap with the cover to play a limiting role.

[0044] In some embodiments, a pressure head 221 is provided at the output end of the driving member 22, and the pressure head 221 can pass through the second notch 2112 and press the cover.

[0045] By providing the pressure head 221, the pressure head 221 can contact the cover to the greatest extent to provide a uniform pressing force, improving the pressure holding effect and the fitting effect. The pressure head 221 cooperates with the second notch 2112. The pressure head 221 is detachably installed at the output end of the driving member 22, which is convenient for replacement to adapt to the formation of the second notch 2112 and the area of the cover. After the pressure head 221 passes through the second notch 2112 and contacts and presses the cover, it is beneficial for the pressure head 221 to provide sufficient pressing force to the cover and avoid structural interference.

[0046] In some embodiments, the shape of the second notch 2112 is T-shaped, the cross-sectional shape of the pressing head 221 is T-shaped, and the pressing head 221 is matched with the second notch 2112 so that the pressing head 221 can press the battery cover toward the bottom of the notch through the second notch 2112.

[0047] As Figure 3 shown, by setting the matching shapes of the second notch 2112 and the pressing head 221, after the pressing head 221 passes through the second notch 2112, it can contact and release pressure with the battery cover over a relatively large area, especially the edge area of the battery cover can obtain a uniform pressing and fitting effect.

[0048] In some embodiments, the control panel 12 is provided with mounting holes 121 for mounting the control component 3.

[0049] As Figure 1 and Figure 4 shown, the control panel 12 is arranged on the kick surface of the stepped structure, and the step panel 11 is arranged on the step surface of the stepped structure. In this embodiment, the control component 3 includes a start button 31, a reset button 32, and a timer 33, which are respectively installed in three mounting holes 121 on the control panel 12. The control component 3 is arranged opposite to the corresponding positioning member 21. During operation, first operate the start button 31, the driving member 22 performs pressure holding, the timer 33 starts timing, and after the timing ends, operate the reset button 32 to end the pressure holding and reset the driving member 22. By providing the mounting holes 121 on the control panel 12 to install the control component 3, it is beneficial to apply force to the control component 3, and the consistent setting of the control components 3 on the same control panel 12 is beneficial for the operator to sequentially operate the pressure holding processes of multiple batteries on the same step.

[0050] In some embodiments, handles 4 are respectively provided on the two wing plates of the frame 1 along the length direction of the step panel 11.

[0051] As Figure 1 shown, there are two handles 4, which are convenient for moving the entire frame 1.

[0052] It should be supplemented that the frame 1 is internally provided with a receiving cavity, and a power supply, a radiator, etc. are arranged in the receiving cavity for supplying power and heat dissipation to the battery pressure holding component 2 and the control component 3.

[0053] The multi-point pressure holding device provided by the present utility model realizes the multi-row and multi-column setting of multiple battery pressure holding components 2 along the height direction and the length direction of the step panel 11 through the stepped frame 1, realizes the multi-point pressure holding operation, is suitable for the pressure holding process of small lithium batteries, and is especially suitable for the pressure holding assembly of 18650 model lithium batteries.

[0054] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
