[0001] The utility model discloses a plastic component connection assembly for a vehicle cooling system, and relates to the field of vehicle cooling systems. Background Art

[0002] With the continuous innovation and change of vehicle engine technology, the engine has an increasingly higher demand for vehicle cooling systems. When the vehicle cooling system adopts a high-position sealed radiator, a low-position plastic expansion water tank must be added at an appropriate position of the vehicle. The main function of the expansion water tank is to provide a proper expansion space for the coolant in the cooling system, and to promptly remove the air accumulated in the cooling system and the water vapor generated at high temperature of the engine when the engine is working normally, while satisfying the water replenishment function of the cooling system, so as to more effectively utilize the heat dissipation function of the radiator and improve the cooling efficiency of the vehicle cooling system.

[0003] At present, the expansion tank is usually installed on the expansion tank bracket fixed to the body sheet metal by bolts. Since the operating space of the bolt wrench needs to be considered during installation, the expansion tank installation structure often occupies a large amount of installation space. To this end, we provide a vehicle cooling system plastic parts connection assembly to solve the above problem. Utility Model Content

[0026] The inner bottom wall of the fixing bracket 1 is provided with a groove 10. The groove 10 provided on the inner bottom wall of the fixing bracket 1 can limit the placement position of the expansion water tank and improve the stability of its placement.

[0027] The interior of the fixed bracket 1 is provided with a horizontal limiting mechanism 2 and a vertical limiting mechanism 3 for connecting and fixing the plastic parts of the vehicle cooling system. The expansion water tank in the vehicle cooling system is placed in the fixed bracket 1 on the expansion water tank bracket fixed to the body sheet metal, and the horizontal limiting mechanism 2 and the vertical limiting mechanism 3 are used to limit and fix it in the horizontal and vertical directions, so as to keep it in a stable state.

[0028] The expansion water tank can be made of plastic materials such as polypropylene. The expansion water tank made of this material has the characteristics of good transparency, excellent high and low temperature resistance, and strong resistance to coolant corrosion. It can be used in a temperature environment of -40℃ to 130℃ and is not easy to change color.

[0029] The horizontal limiting mechanism 2 includes a first fixed rod 201 fixedly connected to the fixed bracket 1, and a first limiting plate 205 arranged inside the fixed bracket 1.

The inner wall of the second slider 302 is hinged to the second support rod 304 through a pin shaft. The first slider 202 and the support plate 305 are both hinged to the second support rod 304.

[0035] The second fixing rod 301 is fixed in the inner wall of the fixing bracket 1. After the support plate 305 moves, the second support rod 304 can drive the second slider 302 to slide left and right on the outer surface of the second fixing rod 301. There are two second support rods 304 hinged to the same second slider 302.

[0036] The inner top wall of the fixed bracket 1 is fixedly connected to the second sleeve 7, the inner wall of the second sleeve 7 is slidably connected to the second slide bar 8, the second slide bar 8 is fixedly connected to the support plate 305, the second sleeve 7 is fixed to the inner top wall of the fixed bracket 1, the second slide bar 8 is fixed to the upper surface of the support plate 305 and can slide in the inner wall of the second sleeve 7, and can guide the support plate 305 when it moves, thereby improving the stability of the support plate 305 when it moves in the vertical direction.

[0037] A fourth spring 9 is fixedly connected to the inner wall of the second sleeve 7, and the second slide rod 8 is fixedly connected to the fourth spring 9. Both ends of the fourth spring 9 are respectively fixed to the second sleeve 7 and the second slide rod 8. When the second slide rod 8 slides in the inner wall of the second sleeve 7, the fourth spring 9 is compressed to cause it to produce elastic deformation, and the reset effect of the fourth spring 9 is used to drive the second slide rod 8 to move in the direction away from the second sleeve 7.

[0038] The inner wall of the support plate 305 is slidably connected to a connecting rod 306 fixedly connected to the second limiting plate 307. The outer surface of the connecting rod 306 is sleeved with a second spring 303. The second spring 303 is fixedly connected to the support plate 305. The second spring 303 is fixedly connected to the second limiting plate 307.

[0039] The top end of the connecting rod 306 is fixedly connected to a limiting block 11 . The limiting block 11 fixed to the top end of the connecting rod 306 can limit the maximum movement position of the connecting rod 306 to prevent it from slipping out of the reserved hole on the support plate 305 .

[0040] In the present invention, both the first limiting plate 205 and the second limiting plate 307 are provided with anti-skid grooves, which can enhance the friction of the contact surface when the expansion water tank in the vehicle cooling system is limited and fixed, thereby improving the stability when it is fixed.

[0041] The components in the drawings of the present invention are only for style reference and are not for specific size standards. The specific sizes are determined according to the actual requirements of production. At the same time, the materials of the components can be replaced accordingly according to actual needs.

[0042] Working principle: The expansion water tank fixing frame in the vehicle cooling system is fixed to the body sheet metal with bolts, and then the two first limit plates 205 are pulled outward to move in opposite directions, and the second limit plate 307 is pulled upward to leave enough space for the expansion water tank. After the first limit plate 205 moves, the first support rod 204 hinged thereto can drive the first slider 202 to slide on the outer surface of the first fixing rod 201. After the first slider 202 moves, it will compress the first spring 203 to cause it to produce elastic deformation. After the first slider 202 moves, the second slider 302 can be driven to slide on the outer surface of the second fixing rod 301 through the second support rod 304 hinged thereto, and then the support plate 304 can be driven to move. When the second limit plate 307 moves downward, the second limit plate 307 moves upward, which drives the connecting rod 306 to slide upward in the inner wall of the support plate 305 and compresses the second spring 303 to make it elastically deformed. Then, the expansion water tank is placed therein, and the first limit plate 205 and the second limit plate 307 are loosened. Under the resetting action of the first spring 203 and the second limit plate 307, the first limit plate 205 and the second spring 303 can be respectively driven to approach the two side surfaces and the upper surface of the expansion water tank, thereby realizing the limit fixation of the expansion water tank in the horizontal and vertical directions, thereby keeping it in a stable state, without the need to use bolts for installation and fixing, and further without considering the operating space of the bolt wrench, thereby reducing the space occupied by the expansion water tank installation structure.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
