Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted energy storage cabinet technology, specifically a vehicle-mounted energy storage cabinet PACK support frame. Background Technology

[0002] The battery pack support frame is the "skeleton" that ensures the stability, safe operation, and performance of the battery pack structure. Its design rationality directly affects the reliability, safety, and service life of the battery pack.

[0003] The existing utility model patent with publication number CN222801884U discloses a liquid-cooled bracket and battery pack for vehicle-mounted battery packs, relating to the field of battery pack technology. It includes a liquid-cooled plate, a base, a first connector, and supporting components. One side of the liquid-cooled plate has several bases, and the bases have the first connector for connecting the battery module. The other side of the liquid-cooled plate has several supporting components. The liquid-cooled bracket, formed by the liquid-cooled plate, base, first connector, and supporting components, possesses good load-bearing capacity and heat dissipation performance. Furthermore, integrating the base, first connector, and supporting components onto the liquid-cooled plate results in a small size, light weight, and ease of use.

[0004] The aforementioned liquid-cooled bracket attaches to the upper battery module via a liquid-cooled plate on one side and contacts the lower battery module via a pad on the other side. However, the distribution of the base and pad may lead to uneven contact area between the liquid-cooled plate and the battery module, causing localized poor heat dissipation. Furthermore, while the support component is described as a "pad" with "a certain degree of elasticity," the material (such as rubber or silicone) is not specified. In a vehicle environment, the pad bears the weight and vibration loads of the battery module for extended periods, making it prone to aging and creep, resulting in decreased cushioning performance. This, in turn, increases the gap between the liquid-cooled plate and the lower battery module, raising the contact thermal resistance and weakening the heat dissipation effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vehicle-mounted energy storage cabinet PACK support frame, which solves the problems of not being able to ensure that the liquid cooling plate and the battery module are always in close contact, and the deviation in the contact area between the liquid cooling plate and the battery module caused by the support structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vehicle-mounted energy storage cabinet PACK support frame includes a limiting frame, and a support mechanism is provided above the limiting frame.

[0007] A connecting component, located inside the limiting frame, is used to limit the relative position between the heat-conducting component and the limiting frame;

[0008] The heat-conducting component includes a connecting rod disposed inside a support mechanism. Side grooves are fixedly installed at both ends of the connecting rod, and a limiting rod is fixedly installed at the center of the connecting rod. A bottom plate and a top plate are fitted between the side grooves and the limiting rod. A flow channel is provided on one side of the bottom plate and the top plate, and a sealing strip is fitted on the top of the bottom plate.

[0009] Preferably, the connecting assembly includes a support block fixedly installed at the bottom of the limiting frame, and a limiting tube and a spring inside the limiting frame. The connecting assembly also includes a positioning post fixedly installed below the limiting rod and the base plate.

[0010] Preferably, there are nine support blocks, which are installed at equal intervals at both ends and the center of the bottom of the limiting frame. The support blocks are hollow tubular silicone tubes, and there are six limiting tubes made of silicone, which are fixedly installed at the four corners and the center inside the limiting frame.

[0011] Preferably, the installation positions of the limiting tube at the center of the limiting frame and the positioning column below the limiting rod are matched, the installation positions of the limiting tubes at the four corners of the limiting frame and the positioning columns below the bottom plates on both sides are matched, and the positioning columns and the limiting tubes form a sliding connection.

[0012] Preferably, the connecting rod, side groove, and limiting rod are connected by bolts, and the bottom plate and top plate are provided with protruding structures on both sides that fit into the sliding groove structure on one side of the side groove and the limiting rod.

[0013] Preferably, the top plate is connected to the bottom plate by bolts, the cross-section of the flow channel is half a circle, and the flow channels on the surfaces of the top plate and the bottom plate are combined to form a pipe structure after the top plate and the bottom plate are fixed. There are two sealing strips, located on the inner and outer sides of the flow channel respectively.

[0014] Beneficial effects

[0015] This utility model provides a vehicle-mounted energy storage cabinet PACK support frame. Compared with the prior art, it has the following advantages:

[0016] (1) The vehicle-mounted energy storage cabinet PACK support frame provides upward support to the heat-conducting components through the springs inside the limiting frame, and the top surface of the top plate is located above the top of the limiting frame in the default state. When the battery module is installed, the battery module presses down on the top plate, causing the positioning post to slide down along the limiting tube and compress the spring; the rebound force of the spring acts on the heat-conducting components, continuously applying upward pressure, so that the top plate fits tightly against the bottom of the battery module. Even in dynamic environments such as vehicle vibration, the elastic potential energy of the spring can compensate for the gap, ensuring that the two are always in close contact. At the same time, the limiting tube is made of silicone, which slides with the positioning post, which can not only limit the displacement direction of the heat-conducting components, but also absorb vibration impact through the elastic deformation of silicone, avoiding the gap caused by violent shaking.

[0017] (2) The vehicle-mounted energy storage cabinet PACK support frame forms symmetrical and uniform support points through nine support blocks at the bottom of the limit frame and six internal limit tubes, ensuring that the heat conduction components are balanced and avoiding local tilting. The top plate, as the component in contact with the battery module, is kept flat by the frame structure formed by the side groove, limit rod and connecting rod. The bottom plate and the top plate are connected by bolts, and the protrusions on both sides are fitted into the sliding grooves of the side groove and limit rod, ensuring that the surface of the top plate is flat and without warping, thereby forming a large area of ​​uniform contact with the bottom of the battery module and avoiding the problem of insufficient local contact area.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a vehicle-mounted energy storage cabinet PACK support frame includes a limiting frame 1, and a support mechanism 2 is provided above the limiting frame 1.

[0025] The connecting component 21 is disposed inside the limiting frame 1 to limit the relative position between the heat-conducting component 22 and the limiting frame 1. The connecting component 21 includes a support block 211 fixedly installed at the bottom of the limiting frame 1, and a limiting tube 212 and a spring 213 inside the limiting frame 1. The connecting component 21 also includes a positioning post 214 fixedly installed below the limiting rod 223 and the base plate 224. There are nine support blocks 211, which are equidistantly installed at both ends and the center of the bottom of the limiting frame 1. The support blocks 211 are hollow tubular made of silicone. There are six limiting tubes 212 made of silicone, which are fixedly installed at the four corners and the center inside the limiting frame 1. The installation position of the limiting tube 212 at the center of the limiting frame 1 matches the installation position of the positioning post 214 below the limiting rod 223. The installation positions of the limiting tubes 212 at the four corners of the limiting frame 1 match the installation positions of the positioning posts 214 below the base plates 224 on both sides. The positioning post 214 and the limiting tube 212 form a sliding connection.

[0026] Specifically, the top left and right sides of the limiting frame 1 are provided with elongated openings to fix the battery module above the limiting frame 1 with bolts and nuts. The position of the heat conduction component 22 is restricted by the limiting tube 212 and the positioning post 214 to prevent the heat conduction component 22 from tilting at a large angle. The spring 213 at the bottom can support the upper heat conduction component 22 and increase the relative pressure between the heat conduction component 22 and the battery module through elasticity after the heat conduction component 22 is compressed, thereby improving the fit between the heat conduction component 22 and the bottom of the battery module.

[0027] The heat-conducting assembly 22 includes a connecting rod 221 disposed inside the support mechanism 2. Side grooves 222 are fixedly installed at both ends of the connecting rod 221. A limiting rod 223 is fixedly installed at the center of the connecting rod 221. A base plate 224 and a top plate 225 are fitted between the side grooves 222 and the limiting rod 223. A flow channel 226 is provided on one side of the base plate 224 and the top plate 225. A sealing strip 227 is fitted above the base plate 224. The assembly includes the connecting rod 221, the side grooves 222, and the limiting rod. The components 223 are connected by bolts. The bottom plate 224 and the top plate 225 are provided with protruding structures on both sides that fit into the side groove 222 and the sliding groove structure on one side of the limiting rod 223. The top plate 225 is connected to the bottom plate 224 by bolts. The cross section of the flow channel 226 is half a circle. After the top plate 225 and the bottom plate 224 are fixed, the flow channel 226 on the surface of the top plate 225 and the bottom plate 224 are enclosed to form a pipe structure. There are two sealing strips 227, which are located on the inner and outer sides of the flow channel 226 respectively.

[0028] Specifically, the connecting rod 221 can limit the position of the side groove 222 and the limiting rod 223. After the bottom plate 224 and the top plate 225 are connected by bolts, the protruding structures on both sides of the bottom plate 224 and the top plate 225 fit into the groove structures on one side of the side groove 222 and both sides of the limiting rod 223. The relative position between the bottom plate 224 and the top plate 225 is limited by the frame structure formed by the connecting rod 221, the side groove 222, and the limiting rod 223. After the bottom plate 224 and the top plate 225 are connected, the flow channel 226 between the top plate 225 and the bottom plate 224 forms a pipe structure to facilitate the introduction of circulating cooling medium between the top plate 225 and the bottom plate 224 to remove the heat of the battery. Without the influence of external force, the bottom of the bottom plate 224 contacts the highest point of the central protrusion of the spring 213, and the upper surface of the top plate 225 is located above the top of the limiting frame 1. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0029] During operation, the limiting frame 1 serves as the overall frame. The battery module is fixed to the top with bolts, and nine hollow tubular silicone support blocks 211 are installed at both ends and the center at the bottom, contacting the vehicle-mounted equipment to buffer vibration. The six silicone limiting tubes 212 at the four corners and the center inside slide and engage with the limiting rods 223 in the heat conduction assembly 22 and the positioning posts 214 below the base plate 224 to restrict the position of the heat conduction assembly 22 and prevent tilting. The springs 213 inside the limiting frame 1 provide upward support to the heat conduction assembly 22. In the default state, the top surface of the top plate 225 is located above the top of the limiting frame 1. When the battery module is installed, the battery module will press down on the top plate 225, causing the positioning posts 214 to slide down along the limiting tubes 212 and compress the springs. 213. The rebound force generated by the spring 213 will cause the top plate 225 of the heat conduction component 22 to fit more tightly against the bottom of the battery module, further improving the fit. In the heat conduction component 22, the connecting rod 221, the side groove 222, and the limiting rod 223 are connected by bolts to form a frame. The bottom plate 224 and the top plate 225 are fitted into the sliding grooves of the side groove 222 and the limiting rod 223 and are connected by bolts. The semi-circular flow channels 226 on the surfaces of the two form a closed pipe for the cooling medium to circulate and absorb the battery heat. The two sealing strips 227 above the bottom plate 224 are located inside and outside the flow channel 226 to prevent medium leakage. The whole structure works together through structural limiting, elastic support and efficient heat conduction to ensure stable support and heat dissipation of the battery module.
