Description

Technical Field

[0001] This utility model relates to the technical field of automotive powertrain connection components, and more specifically to a battery mounting assembly. Background Technology

[0002] In the powertrain layout of new energy vehicles, the battery pack, as the core energy source, directly affects the vehicle's driving safety and comfort due to the stability of its connection with the vehicle frame. To achieve flexible support and vibration shock absorption for the battery pack, the industry commonly uses battery mounting components as key connecting parts between the battery pack and the vehicle frame support. These components need to simultaneously meet the dual functional requirements of fixing the relative position of the battery pack and isolating vibration transmission.

[0003] In existing technologies, battery mounting assemblies mostly adopt an integrated structural design. The battery mounting assembly includes a rubber damping body, a metal mandrel, and an independent bracket. The independent bracket is used to connect to the battery frame and has pre-drilled mounting holes that match the rubber damping body. The rubber damping body is tightly embedded into the mounting holes of the independent bracket through an interference fit, forming a pre-assembled unit of the bracket and the damping body. A through hole is axially formed in the center of the rubber damping body, the size of which matches the outer diameter of the metal mandrel. The metal mandrel can be directly inserted into the through hole in the center of the rubber damping body and can be removed from the through hole.

[0004] In actual assembly, the independent bracket is first fixed to the battery frame using bolts or welding, forming a single unit with the battery pack. After the battery frame and suspension assembly are in place, the rubber damping body is then securely connected to the frame bracket using a metal mandrel. This rigid connection between the metal mandrel and the frame ultimately completes the flexible connection between the battery pack and the frame via the suspension assembly, achieving vibration isolation. This existing battery suspension assembly technology has the following drawbacks: As an essential intermediate connecting component, the independent bracket not only increases the overall number of parts and manufacturing cost of the suspension assembly, but also requires separate design of the mounting hole's dimensional accuracy to match the interference fit requirements of the rubber shock absorber body, thus increasing the processing difficulty and assembly error risk.

[0005] The additional connection steps between the independent bracket and the battery frame prolong the overall assembly process of the battery pack and the vehicle frame. If the connection position between the independent bracket and the battery frame is misaligned, it will directly cause the coaxiality of the rubber shock absorber body and the metal spindle to shift, thus affecting the damping performance of the suspension components and increasing the workload of later adjustments. In addition, when the rubber shock absorber body needs to be replaced due to aging or wear, the connection between the independent bracket and the battery frame must be removed before the old rubber shock absorber body can be taken out, making the maintenance process cumbersome and increasing the cost of use. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a battery suspension assembly. The rubber shock-absorbing body of the battery suspension assembly is a split structure, which does not require additional independent support. The rubber shock-absorbing body can be directly embedded into the mounting hole of the battery frame to achieve assembly, which effectively reduces the number of parts and manufacturing costs, and simplifies the assembly process and subsequent maintenance and disassembly operations.

[0007] The technical solution of this utility model is to provide a battery suspension assembly, including a rubber shock-absorbing body and a spindle. The rubber shock-absorbing body includes a shock-absorbing body and an end sleeve. The shock-absorbing body has a shaft hole in the middle, and a spindle sleeve is provided in the shaft hole. The end sleeve is sleeved on one end of the shock-absorbing body. The spindle can be inserted into the spindle sleeve.

[0008] Compared with the prior art, the battery suspension assembly of this utility model has the following advantages: by designing the rubber shock-absorbing body as a separate structure of the shock-absorbing body and the end sleeve, and with the mandrel that can be inserted into the mandrel sleeve, there is no need to set up an additional independent bracket. It can be directly embedded into the mounting hole of the battery frame to complete the assembly. This not only reduces the number of parts and lowers the manufacturing cost, but also simplifies the assembly process. It is also convenient to disassemble and assemble the rubber shock-absorbing body during later maintenance, effectively solving the problems of high cost, complex assembly and inconvenient maintenance caused by the existence of independent brackets in existing integrated assemblies.

[0009] As an improvement, the damping body includes a hollow base, one side of which extends outward to form a hollow connecting shaft. The inner cavity of the base and the inner cavity of the connecting shaft form the shaft hole. The end sleeve is fitted onto the end of the connecting shaft. A limiting boss is provided on the side wall of the connecting shaft, and one side of the end sleeve is limited on the limiting boss. With this structure, the limiting boss precisely limits the end sleeve, ensuring a stable connection between the end sleeve and the damping body.

[0010] As an improvement, the stepped surface of the limiting boss is a slope. With this structure, the slope can reduce the contact resistance when assembling the end sleeve, reduce the assembly difficulty, improve the assembly efficiency, and guide the end sleeve to the end of the connecting shaft more smoothly. The slope structure can also enhance the tightness of the fit between the end sleeve and the limiting boss, prevent the end sleeve from loosening and shifting under long-term vibration, and further improve the connection stability and service life of the overall structure of the rubber shock absorber.

[0011] As an improvement, a first groove is provided on the end face of the base away from the connecting shaft, and a first reinforcing pad is embedded in the first groove. The outer end face of the first reinforcing pad is flush with the end face of the base. With this structure, the structural strength of the end face of the base is enhanced by the first reinforcing pad, preventing the base from deforming due to stress during assembly or use. The flush design also ensures a tight seal between the base and the battery frame mounting holes, preventing foreign objects from entering or assembly gaps from affecting connection stability, without increasing the overall volume of the component.

[0012] As an improvement, a first annular deformation groove is provided on the end face of the base near the connecting shaft; a first damping slope is provided at the edge of the base away from the connecting shaft. With this structure, the first annular deformation groove can provide a more reasonable deformation space for the base, improving the buffering and energy absorption effect of the rubber damping body during vibration transmission; the first damping slope can reduce the contact stress between the edge of the base and the battery frame mounting hole, avoiding wear or cracking of the base edge due to stress concentration after long-term use.

[0013] As an improvement, a second groove is provided on the end face of the end sleeve away from the shock-absorbing body, and a second reinforcing pad is embedded in the second groove. The outer end face of the second reinforcing pad is flush with the end face of the end sleeve. With this structure, the structural strength of the end face of the end sleeve is enhanced by the second reinforcing pad, preventing deformation and wear of the end sleeve during assembly or long-term stress. The flush design also ensures the tightness and sealing between the end sleeve and surrounding components, preventing foreign objects from entering or assembly gaps from affecting connection stability, without increasing the volume of the component.

[0014] As an improvement, a second annular deformation groove is provided on the end face of the end sleeve near the shock-absorbing body; a second damping slope is provided at the edge of the end sleeve away from the shock-absorbing body. With this structure, the second annular deformation groove can provide a suitable deformation space for the end sleeve, assisting the rubber shock-absorbing body to improve the overall buffering and energy absorption effect and enhance vibration isolation performance; the second damping slope can reduce the contact stress between the edge of the end sleeve and surrounding components, avoiding wear or cracking of the end sleeve edge due to stress concentration after long-term use.

[0024] like Figures 1 to 5 As shown, this application discloses a battery suspension assembly, including a rubber shock-absorbing body and a spindle (not shown).

[0025] The rubber damping body includes a damping body 1 and an end sleeve 2. The damping body 1 has a shaft hole 101 in its middle, and a mandrel sleeve 102 is disposed within the shaft hole 101. The damping body 1 is made of rubber, and the mandrel sleeve 102 is made of metal. The damping body 1 and the mandrel sleeve 102 are fixed together by vulcanization. The end sleeve 2 is fitted onto one end of the damping body 1. The mandrel can be inserted into the mandrel sleeve 102. The mandrel is made of metal; in this specific embodiment, the mandrel is a screw.

[0026] The shock-absorbing body 1 includes a base 103, which is a hollow structure. One side of the base 103 extends outward to form a connecting shaft 104, which is also a hollow structure. The inner cavity of the base 103 and the inner cavity of the connecting shaft 104 form the shaft hole 101. A limiting boss 105 is provided on the side wall of the connecting shaft 104, and the stepped surface of the limiting boss 105 is an inclined surface 106. The end sleeve 2 is fitted onto the end of the connecting shaft 104, and the end sleeve 2 is limited on the inclined surface 106 of the limiting boss 105.

[0027] A first groove 107 is provided on the end face of the base 103 away from the connecting shaft 104, and a first reinforcing pad 108 is embedded in the first groove 107. The outer end face of the first reinforcing pad 108 is flush with the end face of the base 103. In this specific embodiment, the first groove 107 is circular, and correspondingly, the first reinforcing pad 108 is also circular. The first reinforcing pad 108 is made of metal material, and the first reinforcing pad 108 is vulcanized and fixed to the base 103. A first annular deformation groove 109 is provided on the end face of the base 103 near the connecting shaft 104; a first damping slope 110 is provided at the edge of the end of the base 103 away from the connecting shaft 104.

[0028] The end sleeve 2 has a second groove 201 on its end face away from the shock-absorbing body 1. A second reinforcing pad 202 is embedded in the second groove 201, and the outer end face of the second reinforcing pad 202 is flush with the end face of the end sleeve 2. In this specific embodiment, the second groove 201 is circular, and correspondingly, the second reinforcing pad 202 is also circular. The second reinforcing pad 202 is made of metal material, and it is fixed to the end sleeve 2 by vulcanization. The end sleeve 2 has a second annular deformation groove 203 on its end face near the shock-absorbing body 1; and a second shock-absorbing inclined surface 204 is provided at the edge of the end of the end sleeve 2 away from the shock-absorbing body 1.

[0029] When using the battery mounting assembly of this application, the rubber shock absorber body (composed of shock absorber body 1 and end sleeve 2) is first directly embedded into the mounting hole of the battery frame to complete the positioning of the assembly and the battery frame; then the position of the battery frame is adjusted so that the hole of the inner core sleeve 102 of the rubber shock absorber body is aligned with the hole on the vehicle frame bracket; then the metal core (screw) is passed through the hole of the vehicle frame bracket and inserted into the core sleeve 102, so that the nut at one end of the core is naturally limited to the outside of the vehicle frame bracket; finally, the nut is screwed on and locked at the other end of the core, thus completing the flexible connection between the battery pack and the vehicle frame through the mounting assembly; when the rubber shock absorber body needs to be replaced for later maintenance, simply unscrew the nut at the end of the core and remove the core, and the rubber shock absorber body (including shock absorber body 1 and end sleeve 2) can be removed from the mounting hole of the battery frame for replacement.

[0030] This battery suspension assembly features a separate structure for the rubber shock absorber body 1 and the end sleeve 2, eliminating the need for an additional independent bracket as in existing technologies. It can be directly embedded into the mounting holes on the battery frame for assembly, effectively reducing the number of parts and lowering manufacturing costs. Furthermore, it eliminates the additional connection steps between the independent bracket and the battery frame, significantly simplifying the assembly process and avoiding coaxiality issues caused by misalignment of the independent bracket. Moreover, during later maintenance, there is no need to remove the independent bracket; simply unscrewing the nut and removing the spindle allows for replacement of the rubber shock absorber body (including shock absorber body 1 and end sleeve 2), significantly simplifying disassembly and assembly and improving maintenance convenience.
