Description

Technical Field

[0001] This utility model relates to the technical field of battery trays, and in particular to a battery tray for automobiles. Background Technology

[0002] In new energy vehicles, the current common practice is to install the power battery on the vehicle's tray, which saves space and concentrates the weight of the power battery at the bottom of the vehicle, improving the vehicle's stability.

[0003] Existing battery trays, such as the battery tray for new energy electric vehicles disclosed in utility model patent application number 201921995878.8, mainly include a base plate and side beams. An embedded block is provided between the base plate and the side beams. The embedded block has a first step feature on the upper part near the side beam, and the embedded block has a bridge structure on the side near the base plate. The side beam has a second step feature on the lower part near the embedded block. In use, the segmented side beam semi-finished products are spliced ​​into an integral frame. Using TIG welding equipment, they are welded into an integral side beam. The groove on one side of the embedded block is embedded into the vertical rib of the base plate. The embedded block is initially fixed to the base plate through partial TIG welding or tight fitting. Then, the embedded block and the base plate are placed into the side beam frame as a whole. The joint area of ​​the side beam, embedded block and base plate is stirred together by friction stir welding equipment, so that the strength of the interface exceeds that of other areas.

[0004] However, the existing brackets have poor heat dissipation. If the battery heat cannot be dissipated in time, the new energy vehicle may spontaneously combust, threatening the safety of people. Moreover, the vehicle may be subjected to bumps during driving, and the existing brackets have poor shock absorption, which can easily damage the battery. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automotive battery tray that not only facilitates battery heat dissipation and improves the heat dissipation effect of the tray to avoid heat accumulation, but also enhances the shock absorption effect of the device to prevent battery damage from vibration during vehicle operation.

[0006] This utility model discloses a battery tray for automobiles, including a fixing mechanism; it also includes an air inlet mechanism, multiple sets of support mechanisms, four sets of pressing mechanisms, and an exhaust mechanism. The air inlet mechanism is installed on the fixing mechanism to facilitate the entry of fresh air, the support mechanisms are installed on the fixing mechanism to support the battery, the four sets of pressing mechanisms are all installed on the fixing mechanism to fix the battery, and the exhaust mechanism is installed on the fixing mechanism to facilitate heat dissipation. When the operator places the battery in the fixing mechanism, the multiple sets of support mechanisms support the battery, and the four sets of pressing mechanisms press and fix the battery. By setting multiple sets of support mechanisms and four sets of pressing mechanisms, the vibration of the battery can be reduced. The fixing mechanism is fixed to the vehicle frame with bolts. When the vehicle is in motion, fresh air enters the fixing mechanism through the air inlet mechanism, and the fresh air carries the heat generated by the battery and is discharged through the exhaust mechanism to facilitate battery heat dissipation.

[0007] Preferably, the fixing mechanism includes a bracket, four sets of fixing plates, and eight sets of ribs. The bracket has multiple sets of ventilation holes. All four sets of fixing plates are installed on the bracket, and the fixing plates have positioning holes. Ribs are installed on both sides of each set of fixing plates. The operator uses bolts to pass through the four sets of fixing plates to fix the bracket to the vehicle frame. The ribs enhance the connection stability between the fixing plates and the bracket. The bracket protects the battery and prevents it from being scratched by the ground.

[0008] Preferably, the bracket is made of aluminum alloy; aluminum alloy is lighter, which can reduce the overall weight of the vehicle and avoid affecting the vehicle's range.

[0009] Preferably, the bracket surface is coated with an insulating ceramic coating; by applying the insulating ceramic coating, the insulation effect of the bracket is enhanced, and the battery leakage is prevented from causing greater safety hazards.

[0010] Preferably, the air intake mechanism includes an air intake filter, a wind deflector, a positioning frame, and a spoiler grille. The air intake filter is mounted on the bracket, the wind deflector is mounted on the bracket, the positioning frame is mounted on the bracket, and the spoiler grille is mounted on the positioning frame. The positioning frame facilitates battery positioning. During vehicle movement, fresh air enters the bracket through the air intake filter. The wind deflector and spoiler grille guide the airflow, facilitating airflow through the battery and carrying away the heat generated by the battery, thus facilitating battery heat dissipation.

[0011] Preferably, the support mechanism includes multiple sets of first dampers, multiple sets of first shock-absorbing springs, and first shock-absorbing pads. The bracket has multiple sets of limiting grooves, and the multiple sets of first dampers are all installed in the limiting grooves of the bracket. The multiple sets of first shock-absorbing springs are respectively fitted onto the multiple sets of first dampers. The bottom end of the first shock-absorbing pad is connected to the top end of the multiple sets of first dampers. The multiple sets of first shock-absorbing pads support the battery. When the vehicle vibrates, the multiple sets of first dampers and multiple sets of first shock-absorbing springs buffer and absorb shock, reducing the impact force on the battery.

[0012] Preferably, the pressing mechanism includes a pressing plate, two sets of magnetic snap fasteners, multiple sets of second dampers, multiple sets of second shock-absorbing springs, and a second shock-absorbing pad. The pressing plate is rotatably mounted on the bracket, and both sets of magnetic snap fasteners are mounted on the pressing plate. The top ends of the multiple sets of second dampers are connected to the bottom ends of the pressing plate, and the multiple sets of second shock-absorbing springs are respectively fitted onto the multiple sets of second dampers. The top end of the second shock-absorbing pad is connected to the bottom ends of the multiple sets of second dampers. After the operator places the battery on the multiple support mechanisms, the pressing plate is rotated so that the two sets of magnetic snap fasteners are attracted to the positioning frame, and the second shock-absorbing pad presses and fixes the battery. The vibration of the battery is reduced by setting multiple sets of second dampers and multiple sets of second shock-absorbing springs.

[0013] Preferably, the exhaust mechanism includes an exhaust grille, a motor, a rotating shaft, and three sets of fan blades. The exhaust grille is mounted on a bracket, the motor is mounted on the bracket, the rotating shaft is rotatably mounted on the bracket, and all three sets of fan blades are mounted on the rotating shaft. Heat-laden air is discharged through the exhaust grille. The motor is started, and the motor drives the rotating shaft to rotate. The rotating shaft drives the three sets of fan blades to rotate, accelerating airflow and enhancing heat dissipation.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff places the battery in the fixing mechanism, multiple sets of support mechanisms support the battery, and four sets of pressing mechanisms press and fix the battery. By setting multiple sets of support mechanisms and four sets of pressing mechanisms, the vibration of the battery can be reduced. The fixing mechanism is fixedly installed on the vehicle frame with bolts. When the vehicle is running, fresh air enters the fixing mechanism through the air intake mechanism. The fresh air carries the heat generated by the battery and is discharged through the exhaust mechanism, which facilitates the heat dissipation of the battery. Attached Figure Description
