[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a circuit board structure for a new energy battery pack, comprising a circuit board body 1, with connection mechanisms 2 for quick disassembly and assembly provided at both ends of the circuit board body 1, a mounting mechanism 4 for mounting and fixing provided at the outer end of the connection mechanism 2, a heat dissipation mechanism 3 for absorbing heat provided at the bottom of the circuit board body 1, and positioning holes 21 in the connection mechanism 2 respectively provided at both ends of the top of the circuit board body 1;

[0024] A support seat 23 is installed at the bottom of the circuit board body 1, and a fixing groove 22 is provided at the top of the support seat 23 and the center of the two ends of the top of the circuit board body 1. A fixing block 28 is slidably connected inside the fixing groove 22, and a push plate 27 is fixedly installed on the outside of the fixing block 28. An elastic component is provided on the outside of the push plate 27, and a positioning block 24 is fixedly installed on the top of the support seat 23.

[0025] It is conducive to achieving limited support and can adopt the effect of elastic clamping and fixing at the same time, so as to improve the required assembly and disassembly efficiency and convenience, and facilitate people's use.

[0026] Preferably, the elastic component includes a spring 25 and a telescopic rod 26, both of which are fixedly mounted on the outside of the push plate 27. The spring 25 is located on the outside of the telescopic rod 26, and the elastic push facilitates self-propelled adaptive operation when fixed.

[0027] Among them, a threaded hole is opened at the top of the fixing block 28, and a threaded groove is opened at the bottom of the inner cavity of the fixing groove 22. A fastening screw 29 is slidably connected inside the threaded hole. The threaded hole and the threaded groove are opened to facilitate the adaptation of the fastening screw 29 and threaded connection with it.

[0028] Among them, the positioning block 24 is inserted into the inside of the positioning hole 21, and a connecting plate is fixedly installed on the outer end of the support seat 23. A mounting hole is opened in the middle of one side of the connecting plate. The connecting plate and the opening of the mounting hole facilitate the installation of the support seat 23 on the mounting seat 42.

[0029] The installation status is shown in the figure:

[0030] During disassembly, the push plate 27 is simultaneously pulled outward, and the push plate 27 compresses the spring 25 and the telescopic rod 26, which in turn drives the fixing block 28 to slide inside the fixing groove 22, from the top of the circuit board body 1 to the top of the support seat 23. Then, the fastening screw 29 is rotated to extend into the inside of the threaded groove to lock the fixing block 28. At this time, the circuit board body 1 can be lifted upward, and the circuit board body 1 can be separated from the support seat 23 and the positioning block 24 to complete the disassembly operation.

[0031] After repairing or replacing the new circuit board body 1, place it on the top of the support base 23 and insert it into the outer side of the positioning block 24 through the positioning hole 21. Then loosen the fastening screw 29, and then push it according to the elasticity of the spring 25, so that the fixing block 28 slides and is stuck on the top of the circuit board body 1 to complete the fixing operation.

[0032] Furthermore, the heat dissipation mechanism 3 includes a first copper plate 31, which is fixedly mounted on the bottom of the support seat 23. A second copper plate 32 is fixedly mounted on the inner side of the first copper plate 31, and a copper wire 33 is fixedly mounted on the inner side of the first copper plate 31 to facilitate the heat dissipation operation when absorbing heat.

[0033] It can be used to concentrate internal heat by absorbing heat, and then discharge it uniformly with the heat dissipation structure inside the battery pack, so as to form thermal protection for the circuit board to prevent heat from damaging it at the same time.

[0034] Furthermore, the mounting mechanism 4 includes a slider 41, which is fixedly mounted on the connecting plate. The outer ends of the slider 41 are slidably connected to a mounting seat 42, and both ends of the inner side of the mounting seat 42 are provided with a slide groove 43. The slider 41 slides inside the slide groove 43, making it convenient for the circuit board body 1 to be fixedly mounted on the battery pack through the connecting mechanism 2.

[0035] During installation, the connecting plate directly drives the slider 41 to be inserted into the inside of the sliding groove 43 to form a sliding connection therewith, and finally the slider 41 is fastened and installed by screws.

[0036] A new energy battery pack includes a battery pack body for supporting a protective circuit board.

[0037] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
