Description

Technical Field

[0001] The utility model relates to the technical field related to battery pack supporting accessories, and in particular to an electrical compartment supporting structure and a battery pack with an electrical compartment. Background Art

[0002] In the existing battery pack technology, the connection between the electrical compartment maintenance cover and the electrical compartment is mainly a locking connection. Although this connection method can achieve basic fixing and sealing functions, it has many shortcomings in actual use.

[0003] First, the load-bearing effect of the electrical compartment maintenance cover after being connected only by locking is poor. Since the maintenance cover is fixed only by the force provided by the locking device, this connection method is prone to the electrical compartment maintenance cover being concave and the locking device being loosened or deformed when subjected to external force.

[0004] Secondly, when the maintenance cover is affected by external force, it is easy to squeeze the structure inside the electrical compartment. Since the fixing effect of the locking connection is limited, once it is subjected to external force, the maintenance cover may move, thereby squeezing or damaging sensitive components in the electrical compartment such as batteries and circuits. This may not only affect the normal use of the battery pack, but also cause safety hazards such as fire and explosion.

[0005] In summary, the existing battery pack electrical compartment maintenance cover and electrical compartment have defects such as poor load-bearing effect and easy extrusion of the internal structure. An electrical compartment support structure is urgently needed to solve these problems and improve the safety and reliability of the battery pack. Utility Model Content

[0006] In order to overcome at least one of the defects of the prior art, the present invention provides an electrical compartment support structure and a battery pack with an electrical compartment. By introducing a support frame, the problems of poor load-bearing effect and easy extrusion of the internal structure mentioned in the background technology are effectively solved.

[0007] The technical solution adopted by the utility model to solve the problem is:

[0008] An electrical compartment support structure comprises: an electrical compartment shell having a accommodating cavity with an opening on one side; an electrical compartment cover body, the electrical compartment cover body covering the opening of the accommodating cavity; a support frame, the support frame is assembled in the accommodating cavity, and the support frame abuts against the electrical compartment cover body.

[0009] By adopting the above solution, a support frame is set between the electrical compartment cover and the accommodating cavity, which can effectively provide additional supporting force for the electrical compartment cover, making the entire structure more stable when subjected to external force and less likely to loosen or deform. Therefore, this structure can effectively solve the problem of poor load-bearing effect.

[0010] Furthermore, the support frame includes: a supporting body; a first assembly part, the first assembly part is located on one side of the supporting body, and the first assembly part is connected to the bottom wall or side wall of the accommodating cavity; a second assembly part, the second assembly part is located on the other side of the supporting body, and the second assembly part is connected to the electrical compartment cover.

[0011] By adopting the above scheme, the support body improves the supporting strength of the electrical compartment cover, while the first assembly part and the second assembly part facilitate the installation and disassembly of the support body. When replacing the electrical compartment cover, it can be easily disassembled and reinstalled, thereby improving work efficiency.

[0012] Further, the supporting body is a supporting plate, the first assembly portion is a first assembly plate integrally bent and formed with one end of the supporting plate, the first assembly plate is fitted and fixed to the bottom wall of the accommodating cavity, and the second assembly portion is a second assembly plate integrally bent and formed with the other end of the supporting plate, the second assembly plate is fitted and fixed to the electrical compartment cover.

[0013] By adopting the above solution, the entire support frame becomes a solid whole, which not only improves the stability of the structure but also reduces the error caused by assembly.

[0014] Furthermore, two support plates are provided, corresponding to two ends of the second assembly portion respectively, and the angle between the first assembly plate and any of the support plates is in the range of 90°-120°.

[0015] By adopting the above solution, the load-bearing and stability problems in the electrical warehouse support structure can be effectively solved.

[0016] Furthermore, at least one reinforcing beam is arranged between the two support plates.

[0017] By adopting the above solution, the connection strength, overall rigidity and load-bearing capacity between the support plates can be effectively enhanced. Since the reinforcing beam spans across and is connected to the two support plates, an additional support structure is formed, thereby reducing the pressure on the single support plate and preventing it from bending or breaking, so that the entire support frame can more stably resist deformation and displacement when subjected to external force.

[0018] Furthermore, the first assembly plate is parallel to the second assembly plate, and screw holes are arranged on the first assembly plate and / or the second assembly plate.

[0019] By adopting the above solution, the connection stability and firmness between the support frame and the electrical compartment shell and the electrical compartment cover are enhanced.

[0020] Further, the first assembly portion is a first side wall of the support body that is fitted and fixed to the bottom wall of the accommodating cavity, and the second assembly portion is a second side wall of the support body that is fitted and fixed to the electrical compartment cover.

[0021] By adopting the above solution, not only a stable support effect is provided, but also the overall stability and load-bearing capacity of the electrical warehouse are enhanced.

[0022] Furthermore, a second support body is disposed between the first side wall and the bottom wall of the accommodating cavity, and an area of ​​a surface of the second support body in contact with the first side wall is larger than an area of ​​the first side wall.

[0023] By adopting the above scheme, the provision of the second support body increases the contact area between the support frame and the bottom wall of the accommodating cavity, which means that the support points of the support frame on the bottom wall are more dispersed and extensive. This dispersed support method can effectively reduce the situation of single-point force and reduce the risk of structural deformation or damage caused by excessive local pressure, which helps to improve the load-bearing capacity of the support frame and enable it to withstand greater loads without deformation or damage.

[0024] Furthermore, the supporting body and / or the second supporting body has at least one cavity inside, and two opposite sides of the cavity are provided with communication openings.

[0025] By adopting the above solution, not only the overall weight is reduced, but also the structural strength and heat dissipation performance are optimized.

[0026] Furthermore, at least one assembly beam is provided in the accommodating cavity, and the support frame is assembled on the assembly beam; the assembly beam is located between the support frame and the electrical compartment housing and / or between the support frame and the electrical compartment cover.

[0027] By adopting the above solution, the connection stability and firmness between the support frame and the electrical compartment shell and the electrical compartment cover are further enhanced; at the same time, the assembly beam is located between the support frame and the electrical compartment shell and / or between the support frame and the electrical compartment cover. This layout method helps to disperse the external force borne by the support frame. When the electrical compartment cover is subjected to pressure or impact, the assembly beam can effectively absorb and disperse these external forces, reducing the impact and damage to the support frame and the entire electrical compartment structure.

[0028] Further, a sealing gasket is provided between the support frame and the electrical compartment cover; and / or a sealing gasket is provided between the assembly beam and the electrical compartment cover.

[0029] By adopting the above solution, the sealing gasket plays a sealing role, so that the electrical compartment achieves good airtightness when working.

[0030] A battery pack with an electrical compartment comprises a main frame, a battery pack cover and an electrical compartment support structure, wherein the main frame has a battery compartment, the battery compartment is spaced apart from a receiving cavity of an electrical compartment shell, the support frame is arranged in the receiving cavity and respectively abuts against the electrical compartment shell and the electrical compartment cover.

[0031] By adopting the above solution, the goals of space optimization, performance improvement and safety assurance are achieved through the synergy of the main frame, battery pack cover and electrical compartment support structure. At the same time, the electrical compartment cover has load-bearing capacity.

[0032] In summary, the electrical compartment support structure and the battery pack with electrical compartment provided by the utility model have the following technical effects:

[0033] 1. By arranging a support frame in the accommodating cavity in the electrical compartment shell, a stable support is provided to ensure that its internal components can operate stably and are not easily affected by external factors.

[0034] 2. By optimizing the structural design, the support frame can reduce the use of unnecessary materials while ensuring the supporting effect, thereby saving space and cost;

[0035] 3. The support frame assembly process is simpler and faster, reducing assembly difficulty and cost. BRIEF DESCRIPTION OF THE DRAWINGS

The electrical compartment shell 1 has a accommodating cavity 11 with an opening 12 on one side. The electrical compartment cover 2 covers the opening 12 of the accommodating cavity 11. The support frame 3 is assembled in the accommodating cavity 11. The support frame 3 abuts against the electrical compartment cover 2.

Therefore, the structure can effectively solve the problem of poor load-bearing effect.

[0050] Specifically, the support frame 3 includes a support body 31, a first assembly part 32 and a second assembly part 33. The first assembly part 32 is located on one side of the support body 31, and the first assembly part 32 is connected to the bottom wall or side wall of the accommodating cavity 11.

Since the reinforcing beam 37 spans across the two support plates 311 and is connected thereto, an additional supporting structure is formed, thereby reducing the pressure on the single support plate 311 and preventing it from bending or breaking, so that the entire support frame 3 can more stably resist deformation and displacement when subjected to external force.

[0054] In Example 1 and Example 2, the first assembly plate 321 is parallel to the second assembly plate 331. Optionally, screw holes 38 are provided on the first assembly plate 321 and / or the second assembly plate 331. The first assembly plate 321 is fixed to the bottom wall of the accommodating cavity 11 in the electrical compartment shell 1 by passing the screw holes 38 through the fixing screws, and the second assembly plate 331 is fixed to the electrical compartment cover 2. Optionally, the screw holes 38 may not be provided, and the fixing method of the first assembly plate 321 may be changed to welding to improve the connection strength.

Preferably, the angle between the first assembly plate 321 and any of the support plates 311 is 90°, which can effectively solve the load-bearing and stability problems in the electrical warehouse support structure.
