Description

Technical Field

[0001] This utility model relates to the field of battery box processing technology, specifically a battery box side bending device. Background Technology

[0002] In the field of battery box processing technology, with the development of the new energy industry, the demand for high-performance battery boxes has increased significantly. To achieve good sealing and a stable structure, a single, complete material is often cut and processed to construct an overall structure including the box body and side panels. The side panels then need to be precisely bent to shape a specific structure to enhance mechanical strength and sealing performance, ensuring the safe and stable operation of the battery.

[0003] When bending the side panels of a battery box, the lack of an effective support structure inside the battery box means that applying force only to the side can easily cause deformation of the internal structure, affecting the overall quality of the battery box and subsequent battery assembly. Therefore, there is an urgent need to develop a battery box side bending device to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a battery box side bending device, which solves the problem that, due to the lack of an effective support structure inside the battery box, applying force only to the side can easily cause deformation of the internal structure of the battery box, affecting the overall quality of the battery box and subsequent battery assembly issues.

[0005] To achieve the above objectives, this utility model provides a battery box side bending device through the following technical solution, including a box body, a pressing component for bending the side of the battery box is provided on one side of the top of the box body, and clamping components for cooperating with the pressing component are also provided on both sides of the top of the box body.

[0006] It also includes an anti-deformation mechanism, which includes a housing located at the top center inside the box. Two sets of abutment rods are slidably installed through both sides inside the housing, and a side plate for abutting and supporting the inside of the battery box is fixedly installed at one end of the abutment rod. The side plate is L-shaped. A second electric rod is fixedly connected to the bottom of the box. The output end of the second electric rod passes through the inside of the housing and is fixedly connected to the abutment head. The abutment head has a V-shaped cross section. An elastic reset component is also provided on the outside of the housing for resetting the side plate.

[0007] Preferably, the pressing assembly includes a first electric rod disposed on both sides of the top of the box, the output end of the first electric rod is fixedly connected to a slide frame that is slidably connected to the top of the box, the bottom of the slide frame is fixedly connected to two sets of telescopic rods that penetrate the top of the box, and the output end of the telescopic rod is fixedly connected to a semi-circular contact plate for pressing against the side of the battery box.

[0008] Preferably, the clamping assembly includes mounting plates disposed on both sides of the top of the housing, and the mounting plates are provided with clamps for clamping and limiting the battery box to be processed.

[0009] Preferably, the elastic reset assembly includes two sets of springs fixed to the outside of the housing, and one end of each spring is fixedly connected to one side of the side plate.

[0010] Preferably, the housing is further provided with two sets of limiting rods, and the limiting rods are slidably sleeved with limiting seats on the outside, and one side of the limiting seat is fixedly connected to the contact head.

[0011] Preferably, it also includes a shaping component, which includes a mounting bracket disposed on the top of the semi-circular contact plate. A hydraulic rod is fixedly mounted on the top of the mounting bracket, and the output end of the hydraulic rod passes through the top of the mounting bracket and is fixedly connected to a contact seat for pressing and shaping the outer side of the top of the battery box. The contact seat has an L-shaped cross section.

[0012] This invention provides a battery box side bending device. Compared with the prior art, it has the following advantages.

[0013] 1. When the anti-deformation mechanism is working, the second electric rod drives the contact head to move upward, pushes the contact rod to make the side plate extend out of the supporting battery box, and stretches the spring at the same time. When the bending ends, the contact head moves downward, and the spring drives the side plate to return to its original position. This mechanism solves the problem that the inner side of the traditional bent battery box is prone to deformation due to unilateral force, which affects battery assembly and ensures the quality of the battery box.

[0014] 2. After the semi-circular contact plate bends the top side panel of the battery box, the first electric rod drives the mounting bracket to move above the side panel, and the hydraulic rod drives the L-shaped contact seat to move down, pressing and shaping the bent area. This solves the problem of irregular shape after bending, which affects subsequent assembly and use, and improves the aesthetics and structural stability of the battery box.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] First implementation method:

[0023] refer to Figure 1-4 A battery box side bending device includes a box body 1, a pressing component for bending the side of the battery box is provided on one side of the top of the box body 1, and clamping components for cooperating with the pressing component are provided on both sides of the top of the box body 1.

[0024] It also includes an anti-deformation mechanism 3, which includes a housing 301 located at the top center inside the housing 1. Two sets of abutment rods 302 are slidably installed on both sides inside the housing 301. A side plate 303 for abutting and supporting the inside of the battery box is fixedly installed at one end of the abutment rod 302. The side plate 303 is L-shaped. A second electric rod 304 is fixedly connected to the bottom of the housing 1. The output end of the second electric rod 304 passes through the inside of the housing 301 and is fixedly connected to the abutment head 305. The abutment head 305 has a V-shaped cross section. An elastic reset component is also provided on the outside of the housing 301 for resetting the side plate 303.

[0025] The pressing assembly includes a first electric rod 101 disposed on both sides of the top of the housing 1. The output end of the first electric rod 101 is fixedly connected to a slide 102 that is slidably connected to the top of the housing 1. The bottom of the slide 102 is fixedly connected to two sets of telescopic rods 103 that penetrate the top of the housing 1. The output end of the telescopic rod 103 is fixedly connected to a semi-circular contact plate 104 for pressing against the side of the battery box.

[0026] The clamping assembly includes mounting plates 4 disposed on both sides of the top of the housing 1, and the mounting plates 4 are provided with clamps 401 for clamping and limiting the battery box to be processed. The elastic reset assembly includes two sets of springs 306 fixed to the outside of the housing 301, and one end of the springs 306 is fixedly connected to one side of the side plate 303.

[0027] The housing 301 is also provided with two sets of limiting rods 308, and the limiting rods 308 are slidably sleeved on the outside of the limiting seat 307, and one side of the limiting seat 307 is fixedly connected to the contact head 305.

[0028] After the operator places the battery box to be processed upside down on top of the box 1, the battery box is clamped and limited by the clamp 401 in the mounting plate 4.

[0029] When the anti-deformation mechanism 3 is working, the second electric rod 304 moves and drives the contact head 305 to move upward. Due to its V-shaped cross-section structure, the contact head 305 abuts against one side of the contact rod 302, pushing the contact rod 302 to extend horizontally out of the housing 301.

[0030] Since the contact rod 302 is fixedly connected to the side plate 303, the side plate 303 moves synchronously, thereby providing auxiliary support to the inside of the battery box. During this process, the spring 306 connected to the side plate 303 is elastically stretched.

[0031] After the side bending of the battery box is completed, the second electric rod 304 drives the contact head 305 to move down. The contact head 305 moves away from the side of the contact rod 302, and the resistance force on the contact rod 302 disappears. At this time, the spring 306 drives the side plate 303 to return to its original position with its high elasticity. This realizes the function of effectively supporting the inside of the battery box during the side bending process. It solves the problem that the internal structure of the battery box is subjected to excessive pressure due to unilateral force during the traditional bending process, which causes deformation of the inside of the battery box and affects the subsequent battery assembly. This ensures the overall quality of the battery box.

[0032] The movable contact head 305 is restricted by the limiting seat 307 and the limiting rod 308, and can only move along the direction of the limiting rod 308, thereby ensuring the accuracy of the movement path of the contact head 305, making the horizontal extension and retraction of the contact rod 302 more stable and reliable, and further improving the stability and accuracy of the support for the inner side of the battery box.

[0033] Next, the first electric rod 101 operates to drive the slide 102 to move. The slide 102 drives the semi-circular contact plate 104 to move horizontally through the telescopic rod 103. The horizontally moving semi-circular contact plate 104 can abut against the top side panel of the battery box and apply pressure to make the top side panel of the battery box fit against the top of the battery box.

[0034] Subsequently, the first electric rod 101 resets, causing the slide 102, telescopic rod 103, and semi-circular contact plate 104 to reset. Then, the above steps are repeated by another set of first electric rods 101 to bend the other side panel of the battery box, ultimately making the side panel of the battery box fit against the top of the battery box, thus completing the function of bending the bottom side of the battery box. It should be added that because the operator placed the battery box to be processed upside down on top of the box 1, the bottom side panel of the battery box was actually processed and bent.

[0035] Second implementation method:

[0036] After the traditional bending process is completed, the shape of the side bending area is often irregular, which not only affects the aesthetics of the battery box, but also easily causes compatibility problems in the subsequent assembly process, increasing the production difficulty and cost. For this reason, this device is also designed with plastic components, specifically:

[0037] refer to Figure 3 In the second embodiment of this utility model, a shaping component 2 is also included. The shaping component 2 includes a mounting bracket 201 disposed on the top of the semi-arc-shaped contact plate 104. A hydraulic rod 202 is fixedly mounted on the top of the mounting bracket 201, and the output end of the hydraulic rod 202 passes through the top of the mounting bracket 201 and is fixedly connected to a contact seat 203 for pressing and shaping the outer side of the top of the battery box. The contact seat 203 has an L-shaped cross section.

[0038] After the semi-circular contact plate 104 bends the top side panel of the battery box, the first electric rod 101 moves the mounting bracket 201 to above the side panel of the battery box. At this time, the hydraulic rod 202 moves the contact seat 203 downward. Due to its L-shaped cross-sectional structure, the contact seat 203 presses and shapes the bent part of the top side panel of the battery box, realizing the function of further shaping the bent part of the side panel of the battery box. This makes the shape of the bent part more in line with the design requirements, improves the overall aesthetics and structural stability of the battery box, and solves the problem that the shape of the bent part of the side panel is irregular after traditional bending, which affects the subsequent assembly and use of the battery box.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
