Description

Technical Field

[0001] The present invention relates to the technical field of battery packs, and in particular to a battery pack protection component. Background Art

[0002] In traditional battery pack protection components, there are often deficiencies in battery fixation and heat dissipation. Traditional fixation methods often use screws or simple clips, which can easily cause the battery to loosen under vibration or impact conditions. Although elastic elements are now set to alleviate vibration, the amplitude of vibration cannot be limited, which often causes the battery to shake greatly.

[0003] In addition, in the prior art, due to the limited contact area between the heat dissipation medium and the battery surface, the heat generated by the battery during operation cannot be fully removed, resulting in heat accumulation, causing the battery temperature to rise, affecting the performance and life of the battery. In order to solve the above problems, the present invention provides a battery pack protection component. Summary of the invention

[0004] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a battery pack protection assembly, which fixes the battery through the pressure of the heat dissipation medium, so that the heat dissipation medium and the battery are fully in contact to improve the heat dissipation effect. At the same time, the heat dissipation medium and the push-pull part are utilized to limit the battery during vibration to avoid large shaking of the battery.

[0017] Preferably, the push-pull portion comprises:

[0018] A push frame, which is in a "U" shape and is sleeved on the inner end surface of the battery;

[0041] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0042] The present invention provides a battery pack protection component, such as Figures 1 to 9 shown.

[0043] Embodiment 1:

[0044] The present invention provides a battery pack protection component, including a box body 1, wherein a heat dissipation medium is contained in the box body 1, and an addition port is provided on the box body 1, and a sealing plug is provided inside the addition port, so that the heat dissipation medium (the heat dissipation medium can be heat dissipation oil or heat dissipation liquid) can be added to the inside of the box body 1 through the addition port, and a circulation pump 5 is installed on the box body 1, and the box body 1 is connected to a frame body 2 through a connecting component, and the circulation pump 5 is connected to another frame body 2, and the two frames 2 are connected to each other through another connecting component. At the same time, in order to ensure that the two frames 2 are more stable after being connected together and will not be misaligned with each other to cause stress on the battery, a plurality of positioning components 4 are arranged between the two frames 2, so that the two frames 2 can be better kept stable after being connected.

[0045] The frame 2 is provided with a plurality of empty slots 3 adapted to the battery pack. The frame 2 is a hollow structure. Under the action of the circulation pump 5, the heat dissipation medium can circulate between the box 1 and the two frames 2, thereby taking away the heat generated by the battery when working.

[0046] An elastic diaphragm 6 is installed on the groove wall of the empty groove 3, and a piston plate 7 is arranged inside the frame 2 and at the notch position of the empty groove 3, and a through groove 8 compatible with the positioning component 4 is opened on the side of the frame 2 at the notch position of the empty groove 3. When the two frames 2 are connected together, the positioning component 4 will be inserted into the corresponding frame 2 through the through groove 8 and press against the corresponding piston plate 7, so that pressure can be applied to the heat-absorbing medium inside the frame 2, and then the elastic diaphragm 6 can be bulged and pressed against the battery. Under the action of multiple elastic diaphragms 6, the battery can be stably fixed.

[0047] At the same time, because the elastic diaphragm 6 is pressed against each side of the battery, the heat absorbing medium can stably contact the battery, better remove the heat generated by the battery during operation, and improve the heat dissipation effect.

[0048] The positioning assembly 4 includes a plurality of intermediate positioning blocks 401 and two end positioning blocks 402. The intermediate positioning blocks 401 are in a "cross" shape, and the end positioning blocks 402 are in a "T" shape. The intermediate positioning blocks 401 and the two end positioning blocks 402 are arranged on the center line of the frame 2, and the plurality of intermediate positioning blocks 401 are distributed between the two end positioning blocks 402 (such as Figure 4 as shown).

[0049] The connecting assembly includes a first pipe 9 and a second pipe 11, a box 1 and a Figure 1 The lower frame 2 shown in the figure is provided with a first pipe 9, and the outer side of the opening end of the first pipe 9 is rotatably sleeved with a threaded frame 10, which is located as shown in FIG. Figure 1 The second pipe 11 is installed at both ends of the upper frame 2 shown in the figure. The outer side of the open end of the second pipe 11 is provided with an external thread that matches the threaded frame 10. The pressure valve 13 is installed inside the second pipe 11. Only when the pressure inside the second pipe 11 is greater than the pressure value set by the pressure valve 13, the pressure valve 13 will open. At this time, the heat dissipation medium can flow smoothly through the second pipe 11. The setting of the pressure valve 13 can be located when the two frames 2 are disassembled. Figure 1 The heat dissipation medium inside the upper frame 2 shown will not be lost, and the pressure valve 13 is a prior art and has been widely used, so the present invention will not be described in detail.

[0050] The end surface of the opening of the second pipe 11 is provided with a sealing groove 12 adapted to the first pipe 9, which can ensure the sealing between the first pipe 9 and the second pipe 11. When installing, place the battery in a position such as Figure 1 The lower frame 2 is inserted into the empty slot 3 shown in the figure, and then the positioning assembly 4 is inserted into the corresponding through slot 8, and then the upper frame 2 is aligned with the battery for installation, as shown in the figure. Figure 1The threaded frame 10 is rotated clockwise in the direction shown, so that the threaded frame 10 and the corresponding second pipe 11 are connected to each other, so that the two frames 2 can be connected together, and then the circulation pump 5 can be started to make the heat dissipation medium circulate continuously between the box body 1 and the two frames 2 to take away the heat generated by the battery.

[0051] A plurality of heat sinks are fixedly connected inside the box 1, and a plurality of heat sinks are fixedly connected to the heat sinks. A fan is clamped on the heat sinks to increase the air flow rate around the heat sinks, thereby cooling the heat sink medium inside the box 1.

[0052] The arrangement of the heat sink, the heat sink fins and the fan are all prior arts and are now widely used, so they are not shown in the figure.

[0053] Embodiment 2:

[0054] On the basis of Example 1, in order to better fix the battery, the middle positioning block 401 and the end positioning block 402 are both set to be hollow structures, and the materials of the middle positioning block 401 and the end positioning block 402 are both elastic materials, and push-pull parts are set at the corners of the middle positioning block 401 and the end positioning block 402.

[0055] A limiting rod 403 is fixedly connected to one side wall inside the middle positioning block 401 and the end positioning block 402. When vibration occurs, under the action of the limiting rod 403, the inner side wall of the middle positioning block 401 and the inner side wall of the end positioning block 402 will deform in directions away from each other, thereby enabling the corresponding push-pull parts to fix the battery.

[0056] The push-pull part includes a push frame 14 and a pull frame 15. The push frame 14 and the pull frame 15 are both U-shaped. The push frame 14 is semi-enclosed and sleeved on the inner end surface of the battery. The pull frame 15 is semi-enclosed and sleeved on the inner end surface of the battery. The end of the battery close to the center of the frame 2 is the inner end, and the other end is the outer end.

[0057] The corners of the middle positioning block 401 and the end positioning block 402 are fixedly connected with a positive arc rod 16 and a reverse arc rod 17. The opening of the reverse arc rod 17 faces the corresponding battery direction, and the direction of the opening of the positive arc rod 16 is opposite to the direction of the corresponding opening of the reverse arc rod 17 (such as Figure 5 as shown).

[0058] The two ends of the open end of the push frame 14 are fixedly connected to the corresponding arch of the positive arc rod 16 through the push rod 18. When the middle positioning block 401 and the end positioning block 402 are deformed, the arch of the positive arc rod 16 will move in the direction of the corresponding battery, so that the corresponding battery can be pushed away from the center of the frame 2 through the corresponding push rod 18 and the push frame 14.

[0059] The two ends of the open end of the pull frame 15 are fixedly connected to the corresponding arch belly of the reverse arc rod 17 through the pull rod 19. When the middle positioning block 401 and the end positioning block 402 are deformed, the arch belly of the reverse arc rod 17 will move away from the corresponding battery, so that the corresponding battery can be pulled toward the center of the frame 2 through the corresponding pull rod 19 and the pull frame 15. Under the action of the push frame 14 and the pull frame 15, the battery can remain stable during vibration.

[0060] The present invention sets the pull rod 19 as an arch structure, so that the opening of the pull rod 19 faces the corresponding battery, and a spring piece 20 is fixedly connected to the arch of the pull rod 19. The spring piece 20 presses against the side wall of the battery under the action of its own elastic force, and when the reverse arc rod 17 pulls the pull frame 15, the pressing force of the spring piece 20 on the battery can be increased. Combined with the oblique thrust of the push rod 18, the battery can be fixed from multiple directions.

[0061] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
