Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to battery mounting structures and electrical equipment. Background Technology

[0002] Batteries are widely used in energy storage systems, transportation, and consumer electronics. A battery mainly consists of a casing, cover, and core.

[0003] In related technologies, in order to improve the battery swapping speed and ensure economic benefits, the battery packs of operating equipment such as drones and electric vehicles are mostly simply fixed, and the installation stability of the batteries still needs to be improved. Utility Model Content

[0004] The embodiments of this application provide a battery mounting structure and electrical equipment, which can improve the technical problems such as the installation stability of the battery, but there is still room for improvement.

[0005] In a first aspect, embodiments of this application provide a battery mounting structure, including:

[0006] The battery pack has a limiting part;

[0007] The mounting bracket has a mounting cavity and an opening communicating with the mounting cavity, so that the battery pack can be installed in the mounting cavity through the opening;

[0008] A limiting member is connected to the mounting bracket. The limiting part is located between the limiting member and the inner bottom wall of the mounting bracket. The side of the limiting part away from the inner bottom wall abuts against the side of the limiting member facing the inner bottom wall.

[0009] In one embodiment, the limiting portion includes a first wedge, and the limiting member includes a second wedge, wherein the first wedge abuts against the second wedge.

[0010] By adopting the above technical solution, after the first wedge and the second wedge are engaged, the second wedge will exert pressure on the first wedge toward the inner bottom wall, that is, the second wedge can play a role in pressing and fixing the first wedge, thereby effectively improving the installation stability of the battery pack.

[0011] In one embodiment, a limiting space is formed between the limiting member and the inner bottom wall of the mounting bracket, and the limiting part can be inserted into the limiting space; and / or,

[0012] The mounting bracket includes a first sidewall and a second sidewall disposed opposite to each other, one end of the limiting member abuts against the first sidewall, and the second end of the limiting member abuts against the second sidewall.

[0013] By adopting the above technical solution, the limiting space can accommodate the limiting part, allowing the limiting part to be inserted into the limiting space and abut against the limiting member. This ensures that the limiting part can be disengaged from the limiting member by moving the battery pack, reducing the impact of the limiting part and the limiting member on the assembly and disassembly of the battery pack. The first and second sidewalls can limit the limiting member, preventing it from moving towards the first and second sidewalls, thereby preventing the battery pack from shaking towards the first and second sidewalls and improving the installation stability of the battery pack.

[0014] In one embodiment, the mounting bracket has a connecting portion, and the limiting member is detachably connected to the connecting portion, wherein the number of the connecting portions is at least two, and the at least two connecting portions are spaced apart along the height direction of the mounting bracket.

[0015] By adopting the above technical solution, the limiting component and the mounting bracket are detachably connected, allowing the limiting component to be installed and removed as needed to adapt to different requirements. Furthermore, the installation position of the limiting component can be adjusted, enabling positional adjustment of the limiting component in the height direction of the mounting bracket, thus allowing the mounting bracket to be adapted to different battery packs.

[0016] In one embodiment, the battery mounting structure further includes a locking assembly that can switch between a locked state and an unlocked state. In the locked state, the locking assembly securely connects the battery pack and the mounting bracket. In the unlocked state, the battery pack is movable relative to the mounting bracket.

[0017] By adopting the above technical solution, when installing the battery pack, the locking component can be unlocked first, and then the battery pack can be moved into the mounting cavity of the mounting bracket. After the battery pack is completely moved into the mounting cavity, the locking component is locked. At this time, the locking component can fix the battery pack and the mounting bracket, and the limiting component can limit the battery pack, thereby ensuring the installation stability of the battery pack.

[0018] When disassembling the battery pack, the locking assembly is in the unlocked state. Then, the battery pack is moved away from the mounting cavity, causing the limiting part and the limiting member to disengage, and finally the battery pack is removed from the mounting cavity, completing the disassembly of the battery pack.

[0019] In one embodiment, the outer wall surface of the battery pack is formed with a plurality of heat sinks.

[0020] By adopting the above technical solutions, the heat dissipation speed and efficiency of the battery pack can be improved.

[0021] In one embodiment, the battery mounting structure further includes a cooling fan connected to the mounting bracket, the cooling fan being used to dissipate heat from the mounting cavity.

[0022] By adopting the above technical solution, the cooling fan can drive the air flow in the mounting cavity, and since the battery pack is installed in the mounting cavity, the cooling fan can dissipate heat from the battery pack, effectively reducing the temperature of the battery pack.

[0023] In one embodiment, the heat sink is disposed opposite to the cooling fan.

[0024] By adopting the above technical solution, the cooling fan can effectively drive the airflow at the heat sink, which can quickly dissipate the heat at the heat sink, thereby improving the heat dissipation efficiency.

[0025] Secondly, embodiments of this application provide an electrical device including the battery mounting structure described above.

[0026] The beneficial effects of the embodiments of this application are as follows:

[0027] In the embodiments of this application, the battery pack can be moved from the opening into the mounting cavity of the mounting bracket, causing the limiting part of the battery pack to move between the limiting member and the inner bottom wall of the mounting bracket. This allows the limiting member to limit the limiting part, preventing it from moving away from the inner bottom wall, thereby preventing the battery pack from moving away from the inner bottom wall and improving the installation stability of the battery pack. In other words, this application, through the cooperation between the limiting part of the battery pack and the limiting member on the mounting bracket, allows the limiting member to limit the battery pack, preventing it from wobbling away from the inner bottom wall, which helps improve the installation stability of the battery pack. Simultaneously, the limiting part and the limiting member are in abutting engagement, so moving the battery pack allows the limiting part to move between the limiting member and the inner bottom wall, or to be pulled out from between the limiting member and the inner bottom wall, thereby reducing the impact of the limiting part and the limiting member on the assembly and disassembly of the battery pack and ensuring the speed of assembly and disassembly.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0039] The following is combined with Figures 1 to 7 This application describes the battery mounting structure and electrical equipment.

[0040] According to the embodiments of the first aspect of this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the battery mounting structure includes a battery pack 1, a mounting bracket 2, and a limiting member 3. The battery pack 1 has a limiting part 11. The mounting bracket 2 forms a mounting cavity 21 and an opening 22 communicating with the mounting cavity 21, so that the battery pack 1 can be installed in the mounting cavity 21 through the opening 22. The limiting member 3 is connected to the mounting bracket 2. The limiting part 11 is located between the limiting member 3 and the inner bottom wall 23 of the mounting bracket 2. The side of the limiting part 11 away from the inner bottom wall 23 abuts against the side of the limiting member 3 facing the inner bottom wall 23.

[0041] According to the battery mounting structure of this application embodiment, the battery pack 1 can be moved from the opening 22 into the mounting cavity 21 of the mounting bracket 2, causing the limiting part 11 of the battery pack 1 to move between the limiting member 3 and the inner bottom wall 23 of the mounting bracket 2. This allows the limiting member 3 to limit the limiting part 11, preventing it from moving away from the inner bottom wall 23, thereby preventing the battery pack 1 from moving away from the inner bottom wall 23 and improving the installation stability of the battery pack 1. In other words, this application, through the cooperation between the limiting part 11 of the battery pack 1 and the limiting member 3 on the mounting bracket 2, enables the limiting member 3 to limit the battery pack 1, preventing it from shaking away from the inner bottom wall 23, which helps to improve the installation stability of the battery pack 1. Meanwhile, since the limiting part 11 and the limiting member 3 are in abutting engagement, the limiting part 11 can be moved between the limiting member 3 and the inner bottom wall 23 by moving the battery pack 1, or the limiting part 11 can be pulled out from between the limiting member 3 and the inner bottom wall 23. This reduces the impact of the setting of the limiting part 11 and the limiting member 3 on the disassembly and assembly of the battery pack 1, and ensures the disassembly and assembly speed of the battery pack 1.

[0042] Understandably, when the battery pack 1 is installed in the mounting cavity 21, the bottom of the battery pack 1 will abut against the inner bottom wall 23 of the mounting bracket 2. At the same time, the limiting member 3 can limit the battery pack 1, thereby improving the installation stability of the battery pack 1 in the direction perpendicular to the inner bottom wall 23.

[0043] It should be noted that the battery pack 1 can also be fixedly connected to the mounting bracket 2 through other connection structures. For example, the battery pack 1 and the mounting bracket 2 can be fixedly connected through a connection structure to prevent the battery pack 1 from moving / wobbling in the direction parallel to the inner bottom wall 23. That is, the foregoing mainly describes the improvement points of this application (the cooperation and limiting of the limiting part 11 and the limiting member 3), but it does not mean that the connection stability between the battery pack 1 and the mounting bracket 2 can only be improved by using the limiting part 11 and the limiting member 3.

[0044] In some examples, the battery pack 1 is moved into the mounting cavity 21 through the opening 22, so that the battery pack 1 abuts against the inner bottom wall 23. Then, the battery pack 1 is pushed, causing it to move further into the mounting cavity 21, thereby moving the limiting part 11 between the limiting member 3 and the inner bottom wall 23. In other words, by moving the battery pack 1, the limiting part 11 can be moved relative to the limiting member 3, so the setting of the limiting part 11 and the limiting member 3 does not increase the difficulty of disassembling and assembling the battery pack 1.

[0045] In some examples, opening 22 is formed on the side wall of mounting bracket 2.

[0046] In some examples, when the height of the battery pack is greater than the height of the mounting cavity 21, a through hole can be provided at the top of the mounting bracket 2, or the top wall of the mounting bracket 2 can be removed to allow the battery pack to move along the inner bottom wall 23.

[0047] In some embodiments, such as Figure 2 and Figure 3 As shown, the limiting part 11 includes a first wedge 111, and the limiting member 3 includes a second wedge 31, with the first wedge 111 abutting against the second wedge 31.

[0048] Understandably, by pushing the battery pack 1 into the mounting cavity 21 through the opening 22 and then continuing to push the battery pack 1, the first wedge 111 and the second wedge 31 can be engaged. The second wedge 31 can limit the first wedge 111, thereby preventing the battery pack 1 from shaking away from the inner bottom wall 23 and improving the installation stability of the battery pack 1.

[0049] It is understandable that the wedge has an inclined surface, and the first wedge 111 and the second wedge 31 are engaged by an inclined surface. After the first wedge 111 and the second wedge 31 are engaged, the second wedge 31 will exert pressure on the first wedge 111 towards the inner bottom wall 23. That is, the second wedge 31 can press and fix the first wedge 111, thereby effectively improving the installation stability of the battery pack 1.

[0050] In some embodiments, such as Figure 3 and Figure 6 As shown, a limiting space 32 is formed between the limiting member 3 and the inner bottom wall 23 of the mounting bracket 2, and the limiting part 11 can be inserted into the limiting space 32.

[0051] It is understandable that the limiting space 32 can accommodate the limiting part 11, so that the limiting part 11 can be inserted into the limiting space 32, so that the limiting part 11 can abut against the limiting member 3, and ensure that by moving the battery pack 1, the limiting part 11 can be disengaged from the limiting member 3, thereby reducing the impact of the limiting part 11 and the limiting member 3 on the disassembly and assembly of the battery pack 1.

[0052] In some embodiments, such as Figure 6 As shown, the mounting bracket 2 includes a first sidewall 24 and a second sidewall 25 disposed opposite to each other. One end of the limiting member 3 abuts against the first sidewall 24, and the second end of the limiting member 3 abuts against the second sidewall 25.

[0053] It is understandable that the first sidewall 24 and the second sidewall 25 can limit the position of the limiting member 3, preventing the limiting member 3 from moving towards the first sidewall 24 and the second sidewall 25, thereby preventing the battery pack 1 from shaking towards the first sidewall 24 and the second sidewall 25, and improving the installation stability of the battery pack 1.

[0054] In some examples, the limiting member 3 is located on the side wall of the mounting bracket 2 opposite to the opening 22. When the battery pack 1 is fully installed into the mounting cavity 21, the limiting member 3 and the limiting part 11 cooperate.

[0055] In some embodiments, the limiting member 3 is integrally formed with the mounting bracket 2.

[0056] In this way, the connection stability between the limiting component 3 and the mounting bracket 2 can be guaranteed.

[0057] In some embodiments, such as Figure 5 and Figure 7 As shown, the mounting bracket 2 has a connecting part 26, and the limiting member 3 is detachably connected to the connecting part 26. The number of connecting parts 26 is at least two, and the at least two connecting parts 26 are distributed at intervals along the height direction of the mounting bracket 2.

[0058] Thus, the limiting member 3 is detachably connected to the mounting bracket 2, and the limiting member 3 can be disassembled and assembled as needed to adapt to different requirements. Furthermore, the installation position of the limiting member 3 can be adjusted, allowing for positional adjustment of the limiting member 3 in the height direction of the mounting bracket 2, thereby enabling the mounting bracket 2 to be adapted to different battery packs 1.

[0059] In some examples, the limiting member 3 can be connected to the connecting part 26 by screws, or by an interference fit. The limiting member 3 can also be connected to the connecting part 26 by any other suitable means.

[0060] In some embodiments, such as Figure 1 and Figure 7 As shown, the battery mounting structure also includes a locking component 4, which can switch between a locked state and an unlocked state. In the locked state, the locking component 4 is fixedly connected to the battery pack 1 and the mounting bracket 2. In the unlocked state, the battery pack 1 can move relative to the mounting bracket 2.

[0061] Understandably, when installing battery pack 1, the locking component 4 can be unlocked first, and then battery pack 1 can be moved into the mounting cavity 21 of the mounting bracket 2. After the battery pack 1 is completely moved into the mounting cavity 21, the locking component 4 can be locked. At this time, the locking component 4 can fix the battery pack 1 and the mounting bracket 2, and the limiting component 3 can limit the battery pack 1, thereby ensuring the installation stability of battery pack 1.

[0062] When disassembling the battery pack 1, the locking component 4 is in the unlocked state, and then the battery pack 1 is moved away from the mounting cavity 21, so that the limiting part 11 and the limiting member 3 are disengaged, and finally the battery pack 1 is disengaged from the mounting cavity 21, thus completing the disassembly of the battery pack 1.

[0063] In some embodiments, such as Figure 1 and Figure 7 As shown, the locking assembly 4 includes, for example, a quick-lock pin 41. Pressing the button on the quick-lock pin 41 retracts the pin terminal, which is the unlocked state. When the button is released, the pin terminal advances, and the front end of the pin terminal inserts into the pin sleeve 42 of the mounting bracket 2, which is the locked state.

[0064] For example, the number of pin sleeves 42 matches the number of pin terminals. The pin sleeves 42 are made of cemented carbide to improve wear resistance. The pin sleeves 42 are assembled onto the mounting bracket 2 by interference fit and are used in conjunction with the pin terminals of the quick-lock pins 41.

[0065] In some embodiments, such as Figure 3 and Figure 4 As shown, multiple heat sinks 12 are formed on the outer wall surface of the battery pack 1.

[0066] In this way, by setting up the heat sink 12, the heat dissipation speed of the battery pack 1 can be improved, and the heat dissipation efficiency can be increased.

[0067] In some embodiments, such as Figure 2 and Figure 5 As shown, the battery mounting structure also includes a cooling fan 5, which is connected to the mounting bracket 2 and is used to dissipate heat from the mounting cavity 21.

[0068] It is understandable that the cooling fan 5 can drive the air flow in the mounting cavity 21, and since the battery pack 1 is installed in the mounting cavity 21, the cooling fan 5 can dissipate heat from the battery pack 1, effectively reducing the temperature of the battery pack 1.

[0069] Specifically, the heat sink 12 is positioned opposite to the cooling fan 5.

[0070] It is understandable that the heat from the battery pack 1 will be transferred to the heat sink 12. The cooling fan 5 is positioned opposite to the heat sink 12, which allows the cooling fan 5 to effectively drive the airflow at the heat sink 12, quickly dissipating the heat at the heat sink 12 and thus improving the heat dissipation efficiency.

[0071] In some embodiments, a guide rail is formed on the inner wall surface of the mounting bracket 2, and the battery pack 1 is slidably connected to the guide rail.

[0072] In this way, battery pack 1 can slide along the guide rail, which facilitates the movement of battery pack 1 relative to mounting bracket 2, thereby improving the ease of disassembly and assembly of battery pack 1.

[0073] In some examples, the bottom of the battery pack 1 is provided with a slider that slides with a guide rail, thereby allowing the battery pack 1 to slide relative to the guide rail.

[0074] According to an embodiment of the second aspect of this application, the electrical equipment includes the battery mounting structure described above.

[0075] According to the embodiments of this application, the battery pack 1 can be moved from the opening 22 into the mounting cavity 21 of the mounting bracket 2, causing the limiting part 11 of the battery pack 1 to move between the limiting member 3 and the inner bottom wall 23 of the mounting bracket 2. This allows the limiting member 3 to limit the limiting part 11, preventing it from moving away from the inner bottom wall 23, thereby preventing the battery pack 1 from moving away from the inner bottom wall 23 and improving the installation stability of the battery pack 1. In other words, this application, through the cooperation of the limiting part 11 of the battery pack 1 and the limiting member 3 on the mounting bracket 2, enables the limiting member 3 to limit the battery pack 1, preventing it from shaking away from the inner bottom wall 23, which helps improve the installation stability of the battery pack 1. Meanwhile, by moving the battery pack 1, the limiting part 11 can be moved between the limiting member 3 and the inner bottom wall 23, or the limiting part 11 can be pulled out from between the limiting member 3 and the inner bottom wall 23, thereby reducing the impact of the setting of the limiting part 11 and the limiting member 3 on the disassembly and assembly of the battery pack 1, and ensuring the disassembly and assembly speed of the battery pack 1.

[0076] It should be noted that electrical equipment can include energy storage power supplies, medical equipment, smart cities, etc. It is important to note that the above are merely illustrative examples of electrical equipment and do not impose any specific limitations on the types of equipment used.

[0077] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
