Description

Technical Field

[0001] This utility model relates to a bottom bracket for a battery tray with a heat dissipation duct. Background Technology

[0002] As a core energy storage component of a vehicle, the battery's operating temperature directly affects its charging and discharging efficiency, cycle life, and safety. During vehicle operation, the battery generates heat due to electrochemical reactions, especially under high-load scenarios such as new energy vehicles or commercial vehicles, where heat accumulation is more pronounced. If this heat cannot be dissipated in time, it can easily lead to thermal runaway risks, while also accelerating plate aging and electrolyte loss, significantly shortening its lifespan.

[0003] Existing vehicle battery mounts mostly only provide a fixing function and lack targeted heat dissipation design. Battery cooling mainly relies on natural ventilation, which is inefficient. Although some improved mounts have added heat dissipation structures, they generally suffer from the following problems:

[0004] First, the cooling airflow can easily mix with the high-temperature gas in the engine compartment, resulting in a significant reduction in cooling efficiency.

[0005] Second, the connection between the bracket and the battery tray and the vehicle body is poorly sealed, resulting in serious airflow leakage and the inability to form a directional and efficient heat dissipation channel.

[0006] Third, the bracket's shock absorption performance is insufficient. Bumps and vibrations during vehicle operation can easily cause mechanical damage to the battery. At the same time, vibrations may also cause the connection parts to loosen, further aggravating airflow leakage.

[0007] Based on the shortcomings of the existing technology, there is an urgent need for a battery tray bottom bracket that combines efficient heat dissipation, reliable fixation, good shock absorption, and sealing performance. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a battery tray bottom bracket with heat dissipation duct that has the advantages of efficient heat dissipation, reliable fixation, good shock absorption and sealing performance.

[0009] To solve the above problems, the present invention adopts the following technical solution:

[0010] A battery tray bottom bracket with a heat dissipation duct includes a side bracket plate and an air intake device fixed to the side of the side bracket plate away from the battery. Two or more interface pipes are provided at the bottom position of the side bracket plate away from the air intake device. A duct bracket is installed through the interface pipes, and a battery tray is fixedly installed through the duct bracket. Cold air input by the air intake device is delivered into the battery tray through the interface pipes and the duct bracket, and acts on the bottom of the battery from bottom to top. A connecting plate for connecting to the vehicle body is provided at the bottom of the side bracket plate.

[0011] Preferably, the air intake device includes an air intake box and a fan. The fan is powered by a battery and starts synchronously when the vehicle starts. The fan is fixedly installed through the air intake box, which is fixedly installed with the side bracket plate. The airflow generated by the fan is input to the interface pipe. A cover is installed at the end of the air intake box away from the side bracket plate. An air intake pipe is provided in the middle of the cover and connected to the vehicle's cooling system through the air intake pipe.

[0012] Preferably, a sealing ring is fitted around the outside of the interface pipe, and the sealing ring seals between the side support plate and the air duct support.

[0013] Preferably, the duct support includes a support rod, which is hollow inside. One end of the support rod is used to insert the interface pipe, and the other end of the support rod is closed. A stepped groove is provided at the top of the support rod, and a stepped hole for installing a battery tray is also provided at the top of the support rod.

[0014] Preferably, a shock-absorbing and sealing frame made of elastic rubber is installed on the stepped surface of the stepped groove, and a shock-absorbing and sealing ring made of elastic rubber is installed on the stepped surface of the stepped hole.

[0015] Preferably, a first stepped groove corresponding to the stepped groove and a first stepped hole corresponding to the stepped hole are provided on both sides of the bottom of the battery tray. The upper end of the shock-absorbing sealing frame is inserted into the first stepped groove, and the upper end of the shock-absorbing sealing ring is inserted into the first stepped hole. Cavities are provided on both sides inside the battery tray. An air outlet groove communicating with the cavities is provided on the inner wall of the battery tray. The first stepped groove communicates with the cavities. A support block is provided inside the battery tray, and a support plate is installed through the support block. The height of the support plate is higher than the air outlet groove. Heat dissipation vents are evenly distributed on the surface of the support plate. The battery is installed in the battery tray by clamps and supported at the bottom by the support plate.

[0016] Preferably, a through groove is provided on the side support plate near the top, and a "7"-shaped fixing rod is slidably installed through the through groove. A first shock-absorbing block is provided on the inner end face of the fixing rod, and a second shock-absorbing block is provided on the side support plate. The side support plate is fixed to the fixing rod by screws.

[0017] Preferably, heat dissipation grooves are provided through the opposite surfaces of the first and second shock absorbers.

[0018] The beneficial effects of this utility model are:

[0019] 1. Efficient directional heat dissipation to ensure battery operating temperature: This utility model directly connects to the vehicle's cooling system through an air inlet pipe, avoiding interference from hot airflow in the engine compartment at the source and ensuring a stable low-temperature cooling air source; at the same time, it constructs a complete directional air duct consisting of "air inlet device - interface pipe - air duct bracket - battery tray cavity - air outlet slot - cooling vents", where cold air penetrates upward from the bottom of the battery, fully contacting the battery and carrying away heat, thus controlling the battery operating temperature within a suitable range and effectively reducing the risk of thermal runaway.

[0020] 2. Multiple sealing design improves air duct utilization: The sealing ring at the interface pipe, the shock-absorbing sealing frame between the air duct bracket and the battery tray, and the shock-absorbing sealing ring form a triple sealing structure, which greatly reduces the air duct leakage rate; the sealing structure works in conjunction with the hollow air duct bracket to ensure that all cold air is directionally delivered to the inside of the battery tray, avoiding airflow waste and further enhancing the heat dissipation effect.

[0021] 3. Integrated shock absorption function to protect the battery structure: The shock-absorbing sealing frame, shock-absorbing sealing ring and first and second shock-absorbing blocks made of elastic rubber material form a comprehensive shock absorption system, which can buffer more than 90% of the bumps and vibrations during vehicle operation; at the same time, the elastic installation structure avoids hard contact between the battery and the bracket, reduces mechanical damage and extends the physical life of the battery.

[0022] 4. Coordinated Fixation and Heat Dissipation for Optimized Structural Rationality: The “7”-shaped fixing rod, together with the shock-absorbing block, provides lateral reinforcement of the battery, and the heat dissipation grooves on the shock-absorbing block reduce obstruction of the battery's heat dissipation surface; the tray support design creates a ventilation space between the bottom of the battery and the tray, and with the evenly distributed heat dissipation vents, ensures that the cool air is evenly distributed to the bottom of the battery, achieving a perfect balance between fixing function and heat dissipation requirements.

[0023] 5. Integrated structure and convenient installation enhance practicality: The side bracket plate and connecting plate are bent and formed as a whole, resulting in high structural strength and reducing assembly steps; each component is quickly positioned and installed using screws and a stepped structure, making later maintenance convenient; the fan starts synchronously with the vehicle, eliminating the need for additional control devices and reducing operating costs.

[0035] See Figure 1 , Figure 2 and Figure 3The diagram shows a battery tray bottom bracket with a cooling duct, comprising a side bracket plate 1 and an air intake device 2 fixed to the side of the side bracket plate 1 away from the battery. Two or more interface pipes 11 are provided at the bottom of the side bracket plate 1 away from the air intake device 2. A duct bracket 3 is installed through the interface pipes 11, and the duct bracket 3 and the interface pipes 11 are fixed together with screws. A battery tray 4 is fixedly installed through the duct bracket 3. Cool air input from the air intake device 2 is delivered into the battery tray 4 through the interface pipes 11 and the duct bracket 3, acting upwards on the bottom of the battery. A connecting plate 5 for connecting to the vehicle body is provided at the bottom of the side bracket plate 1. The connecting plate 5 and the side bracket plate 1 are an integral structure, formed by bending.

[0036] See Figure 3 As shown, the air intake device 2 includes an air intake box 21 and a fan 22. The fan 22 is powered by a battery and starts synchronously when the vehicle starts. The fan 22 is fixedly installed through the air intake box 21. The air intake box 21 is fixedly installed with the side bracket plate 1. The airflow generated by the fan is input to the interface pipe 11. A cover 23 is installed at the end of the air intake box 21 away from the side bracket plate 1. An air intake pipe 24 is provided in the middle of the cover 23, and the air intake pipe 24 is connected to the vehicle's air conditioning system.

[0037] The above technical solution adopts the design of air intake duct 24, which directly draws in the cold air generated by the vehicle's air conditioning system through the duct, avoiding the drawing in of hot air into the engine compartment.

[0038] See Figure 3 As shown, a sealing ring 111 is sleeved on the outside of the interface pipe 11, and the sealing ring 111 seals between the side support plate 1 and the air duct support 3.

[0039] Sealing ring 111 can increase the sealing performance.

[0040] See Figure 3 As shown, the air duct support 3 includes a support rod 31, which is hollow inside. One end of the support rod 31 is used to insert the interface pipe 11, and the other end of the support rod 31 is closed. A stepped groove 32 is provided on the top of the support rod 31, and a stepped hole 33 for installing a battery tray is also provided on the top of the support rod 31.

[0042] In the above technical solution, the shock-absorbing sealing frame 321 and the shock-absorbing sealing ring 331 not only provide a sealing effect to prevent air leakage, but also provide a certain buffering and shock-absorbing effect for the battery tray.

[0043] See Figure 3 and Figure 4 As shown, the battery tray 4 has a first stepped groove 41 corresponding to the stepped groove and a first stepped hole (not shown) corresponding to the stepped hole on both sides of the bottom. The upper end of the shock-absorbing sealing frame 321 is inserted into the first stepped groove 41, and the upper end of the shock-absorbing sealing ring 331 is inserted into the first stepped hole. Cavities 42 are provided on both sides inside the battery tray 4. An air outlet groove 43 communicating with the cavity 42 is provided on the inner wall of the battery tray 4. The first stepped groove 41 communicates with the cavity 42. A support block 44 is provided inside the battery tray 4. A support plate 45 is installed through the support block 44. The height of the support plate 45 is higher than the air outlet groove. Heat dissipation vents 46 are evenly distributed on the surface of the support plate 45. The battery is installed in the battery tray 4 by clamps and supported at the bottom by the support plate 45.

[0044] According to installation requirements, mounting holes for installing clamps are made on the side wall of the battery tray 4.

[0045] In the above technical solution, the shock-absorbing sealing frame 321 and the shock-absorbing sealing ring 331 provide an elastic installation effect for the battery tray 4 and achieve a high sealing effect, allowing cold air to be effectively delivered into the cavity 42.

[0046] See Figure 2 , Figure 3 and Figure 5 As shown, a through groove 121 is provided on the side support plate 1 near the top position. A "7"-shaped fixing rod 131 is slidably installed through the through groove 121. A first shock-absorbing block 141 is provided on the inner end face of the fixing rod 131. A second shock-absorbing block 151 is provided on the side support plate 1. The fixing rod 131 is fixed to the side support plate 1 by screws.

[0047] The above technical solutions are mainly used to further reinforce the storage battery.

[0048] See Figure 5 As shown, heat dissipation grooves 161 are provided through the opposite surfaces of the first damping block 141 and the second damping block 151.

[0049] The heat dissipation groove 161 can reduce the contact area between the first damping block 141 and the second damping block 151 and the battery, thereby reducing the impact on the battery's own heat dissipation.
