Description

Technical Field

[0001] The utility model relates to the technical field of energy batteries, in particular to a clamping device for a new energy battery box with annular side fixed clamping. Background Art

[0002] A new energy battery box is a casing or container used to accommodate and protect lithium-ion batteries, nickel-metal hydride batteries or other types of rechargeable batteries. These batteries are widely used in electric vehicles, hybrid vehicles, energy storage systems, portable electronic devices, etc. The battery box not only provides physical protection but may also include functions such as thermal management, electrical connection, and safety monitoring. During transportation and use, the battery may encounter various vibrations and impacts. Through the clamping device, the battery can be firmly fixed in place, reducing damage caused by external forces. When the vehicle is moving or the device is operating, the battery should not move freely within the battery box, otherwise it may cause damage to internal wires or connectors, and even lead to a short circuit.

[0003] When the existing clamping mechanism of a new energy battery box clamps and fixes the battery box, there is a problem of fewer clamping surfaces. The pressure acting on the battery box will be concentrated on a few points, easily causing local deformation or damage. And the designs of some clamping mechanisms are too complex, resulting in high manufacturing costs and difficult maintenance. Therefore, we propose a clamping device for a new energy battery box with annular side fixed clamping to solve this problem. Summary of the Invention

Specific implementation manners

[0023] In order to more clearly and completely illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings.

[0024] Please refer to Figures 1 - 4 , a clamping device for a new energy battery box with circumferential side fixing and clamping, including a fixed seat 1. A main board is fixedly installed between the inner walls of the fixed seat 1. Two battery panels 2 are placed on the top of the main board. Two first cylinders 3, two second cylinders 4 and three third cylinders 5 are fixedly installed at the bottom of the fixed seat 1. A first pusher 6 and a second pusher are respectively fixedly installed on the output ends of the first cylinder 3 and the second cylinder 4. A plurality of first trapezoidal parts 7 and a plurality of second trapezoidal parts 8 are slidably installed on the top of the main board. The first pusher 6 and the second pusher are used to drive the first trapezoidal parts 7 and the second trapezoidal parts 8 to move. A pressing part 9 is fixedly installed on the output end of the third cylinder 5. The pressing part 9 is used to press the battery panel 2.

[0025] As Figure 1 shown, two limiting plates 10 are fixedly installed on the front side, rear side and right side of the top of the main board. The limiting plates 10 are fixedly connected to the main board by screws. The plurality of limiting plates 10 are arranged in a U shape to position the battery panel 2 and perform preliminary limiting on the battery panel 2.

[0026] As Figure 3 and Figure 4As shown, the first pusher 6 is in the shape of a right trapezoid, the second pusher is in the shape of an isosceles trapezoid. Oblique T-shaped protrusions 14 are provided on the inclined surfaces of both the first pusher 6 and the second pusher. Oblique T-shaped grooves 13 are formed on the inclined surfaces of both the first trapezoidal member 7 and the second trapezoidal member 8. The top and bottom of the oblique T-shaped groove 13 are both open. The oblique T-shaped protrusion 14 is slidably installed in the corresponding oblique T-shaped groove 13.

[0027] Two first positioning seats 11 are fixedly installed on the top of the main board by screws. A vertical T-shaped groove is formed on one side of the first positioning seat 11. A vertical T-shaped protrusion 15 is provided on one side of the first pusher 6. The vertical T-shaped protrusion 15 is slidably installed in the corresponding vertical T-shaped groove.

[0028] It should be noted that by squeezing the inclined surfaces of the first trapezoidal member 7 and the second trapezoidal member 8 through the inclined surfaces of the first pusher 6 and the second pusher respectively, the first trapezoidal member 7 and the second trapezoidal member 8 are driven to perform linear motion. The use of the inclined surface contact between the trapezoidal blocks can reduce sudden impacts to a certain extent and make the motion smoother, which is particularly important for protecting the battery panel 2 from damage; through the cooperation of the oblique T-shaped protrusion 14 and the oblique T-shaped groove 13, the pusher and the trapezoidal member have a self-locking characteristic. When the external force is removed, the system can maintain the current position without retreating, which is very beneficial for applications with fixed positions.

[0029] In the present utility model, a plurality of second positioning seats 12 are fixedly installed on the top of the main board by screws. A slideway is formed between two adjacent second positioning seats 12. The second trapezoidal member 8 is slidably installed in the corresponding slideway to play a role in limiting the second trapezoidal member 8.

[0030] As Figure 3 shown, the pressing frame includes a ring body 16. Two pressing plates 17 are fixedly installed on the outer side of the ring body 16. A rubber plate 18 is fixedly installed at the bottom of the pressing plate 17.

[0031] A protective plate 19 is fixedly installed on one side of the first trapezoidal member 7. The protective plate 19 is made of rubber material.

[0032] It should be noted that flexible materials such as rubber can help evenly disperse the force applied to the battery panel 2, reduce local high-pressure points, and thus avoid deformation of the outer shell of the battery panel 2 or damage to the internal structure; for the parts on the firm side of the battery panel 2, such as the metal frame, no additional protection is required during clamping, while for the parts made of plastic shells or other thinner materials, the protective plate 19 is needed to increase protection.

[0033] As Figure 1 and Figure 3As shown, two cylinders 21 and multiple insertion cylinders 20 are connected to the bottom inner wall of the fixed seat 1. Multiple insertion plates are provided at the bottom of the main board. The insertion plates are slidably clamped in the corresponding insertion cylinders 20. Threaded grooves are formed at the bottom of the main board. The cooperation between the insertion cylinders 20 and the insertion plates facilitates the positioning of the main board, enabling the cylinders 21 to align with the threaded grooves at the bottom of the main board. By inserting screws into the cylinders 21 and screwing them into the threaded grooves, the rapid installation of the main board and the fixed seat 1 is achieved.

[0034] The working principle of the present utility model is as follows: Place two battery panels 2 on the main board, such that the right side of the battery panel 2 abuts against the right limiting plate 10, and the front side or the rear side of the two battery panels 2 respectively abuts against the limiting plate 10 located at the front side or the rear side, that is, both sides of the battery panel 2 abut against the limiting plate 10. Synchronously start the two first cylinders 3 and the second cylinder 4. The first cylinder 3 drives the first pushing member 6 to move downward, thereby squeezing the first trapezoidal member 7 to move rightward to squeeze and clamp the left side of the battery panel 2. The second cylinder 4 drives the second pushing member to move downward, thereby squeezing the two second pushing members to move forward and backward respectively to squeeze and clamp the front side or the rear side of the two battery panels 2. At this time, the front, rear, left, and right four sides of the battery panel 2 are all clamped. Finally, start the three third cylinders 5, thereby driving multiple pressing members 9 to move downward, so that multiple pressing plates 17 press above the battery panel 2, further enhancing the stability of clamping and fixing the battery panel 2.

[0035] Certainly, the present utility model can also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by ordinary technical personnel in the field without any creative labor all fall within the scope protected by the present utility model.
