Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a fixing bracket for an electric vehicle module and its liquid cooling system. Background Technology

[0002] Electric vehicles are vehicles that use electricity as a power source, drive the wheels with an electric motor, and meet all the requirements of road traffic and safety regulations. They belong to new energy vehicles. The battery module and liquid cooling system of electric vehicles need to be installed on the vehicle through a fixed bracket.

[0003] While existing mounting brackets for electric vehicle modules and their liquid cooling systems can accommodate the installation, the low chassis height of electric vehicles makes them susceptible to impacts, which can deform the mounting brackets. Since existing brackets are integrated, damage from impacts necessitates replacement of the entire bracket, resulting in high repair costs, significant waste, and inconvenience. Therefore, we propose a new mounting bracket for electric vehicle modules and their liquid cooling systems to address these issues. Utility Model Content

[0014] 3. Beneficial effects:

[0015] Compared with the prior art, the fixing bracket for the electric vehicle module and its liquid cooling system of this utility model, using the technical solution provided by this utility model, has the following specific details:

[0016] (1) The fixed bracket consists of a protective frame, a support plate and multiple base plates. When the chassis of the car is bumped and the bottom of the fixed bracket is damaged, the base plate at the damaged part can be replaced separately. Compared with the traditional one-piece fixed bracket, it avoids replacing the entire fixed bracket, effectively reducing the vehicle maintenance cost and avoiding waste of resources.

[0017] (2) When replacing the base plate, unscrew the bolts at the four corners of the base plate to remove the base plate. Then take out the base plate to be installed and place the two ends of the base plate on the support plate through the support plate groove. At the same time, the base plate drives the positioning rod to insert into the positioning groove. Through the guide structure formed by the positioning rod and the positioning groove, the installation of the base plate can be positioned and guided so that the first screw hole and the second screw hole can be aligned so that the base plate can be fixed with bolts.

[0026] Please see Figures 1 to 3 A mounting bracket for an electric vehicle module and its liquid cooling system includes a protective frame 1. Support plates 2 are symmetrically fixedly connected to the bottom of both sides of the protective frame 1. Base plates 3 are equidistantly arranged on the support plates 2.

[0027] The bottom of the base plate 3 is provided with a support plate groove 4 at one end corresponding to the support plate 2. The support plate 2 is symmetrically provided with first screw holes 7 at the four corners of the base plate 3. The base plate 3 is provided with second screw holes 8 at the positions corresponding to the first screw holes 7. The top of the base plate 3 corresponding to the second screw holes 8 is connected to a hidden groove 9. The base plate 3 is provided with bolts 10 at the positions corresponding to the second screw holes 8.

[0028] The fixed bracket consists of a protective frame 1, a support plate 2, and multiple base plates 3. When the chassis of the car is bumped and the bottom of the fixed bracket is damaged, the damaged base plate 3 can be replaced separately. Compared with the traditional one-piece fixed bracket, it avoids replacing the entire fixed bracket, effectively reducing the vehicle's maintenance costs and avoiding waste of resources.

[0029] Please see Figures 1 to 3 The protective frame 1 has symmetrical mounting feet 101 fixedly connected to the bottom of both ends. The support plate 2 is fixedly connected to the protective frame 1 by welding and is fixed on the longer side of the protective frame 1. The inner height of the support plate groove 4 matches the thickness of the support plate 2.

[0030] Please see Figures 1 to 3 The bottom ends of the base plate 3 are symmetrically fixed with positioning rods 5. The support plate 2 has a positioning groove 6 through the corresponding position of the positioning rod 5. The positioning rod 5 is a cylinder and its outer diameter matches the inner diameter of the positioning groove 6. When replacing the base plate 3, the bolts 10 at the four corners of the base plate 3 can be unscrewed to remove the base plate 3. Then, the base plate 3 to be installed is taken out, and the two ends of the base plate 3 are placed on the support plate 2 through the support plate groove 4. At the same time, the base plate 3 drives the positioning rod 5 to insert into the positioning groove 6. Through the guide structure formed by the positioning rod 5 and the positioning groove 6, the installation of the base plate 3 can be positioned and guided so that the first screw hole 7 and the second screw hole 8 can be aligned so that the base plate 3 can be fixed by the bolts 10.

[0031] Working principle: When using the mounting bracket for this electric vehicle module and its liquid cooling system, such as Figures 1 to 3As shown, the fixed bracket consists of a protective frame 1, a support plate 2, and multiple base plates 3. When the chassis of the vehicle is bumped and the bottom of the fixed bracket is damaged, the damaged base plate 3 can be replaced individually. Compared to traditional integrated fixed brackets, this avoids replacing the entire fixed bracket, effectively reducing vehicle maintenance costs and preventing resource waste. When replacing the base plate 3, simply unscrew the bolts 10 at the four corners of the base plate 3 to remove it. Then, take out the base plate 3 to be installed, and place it on the support plate 2 through the support plate grooves 4 at both ends. Simultaneously, the base plate 3 drives the positioning rod 5 to insert into the positioning groove 6. The guide structure formed by the positioning rod 5 and the positioning groove 6 positions and guides the installation of the base plate 3, ensuring that the first screw hole 7 and the second screw hole 8 are aligned so that the base plate 3 can be fixed with bolts 10. After the fixed bracket consisting of the protective frame 1, support plate 2, and multiple base plates 3 is assembled, waterproof adhesive is applied to the assembly seams to give the assembled fixed bracket a waterproof effect.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
