[0022] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —:

[0023] This application discloses an automotive front-end frame. See also: An automotive front-end frame... Figure 1 It includes an upper frame 1 and a lower frame 2. The lower frame 2 is used to be installed on the vehicle body. The upper frame 1 is located above the lower frame 2. A positioning component 3 is installed on the lower frame 2. The upper frame 1 and the lower frame 2 are connected and fixed by the positioning component 3.

[0024] See Figure 1 The lower frame 2 has an installation port 21, into which the water tank is inserted, and the lower frame 2 supports the upper flange of the water tank. The lower frame 2 also has an installation space for installing headlights and hood latches.

[0025] See Figure 1 and Figure 2 The upper frame 1 includes an upper frame 11 and positioning posts 12. An installation groove 111 is provided on the side of the upper frame 11 near the lower frame 2. When the upper frame 11 is against the lower end face of the lower frame 2, the upper flange of the water tank is engaged in the installation groove 111, and the upper frame 11 is positioned against the upper end of the water tank. A heat dissipation vent 112 is provided on the upper frame 11, and the vertical projection of the heat dissipation vent 112 is located within the installation opening 21, increasing the contact area between the water tank and the air, which is beneficial for improving heat dissipation efficiency. Several positioning posts 12 are located on the side of the upper frame 11 near the lower frame 2, and these posts are arranged around the outer periphery of the heat dissipation vent 112. Several positioning slots 22 are provided on the lower frame 2, and the position and number of the positioning slots 22 correspond one-to-one with the position and number of the positioning posts 12. The positioning slots 22 are for the corresponding positioning posts 12 to engage.

[0026] See Figure 1 and Figure 3 The number of positioning components 3 is the same as the number of positioning posts 12. Positioning components 3 are used to position the corresponding positioning posts 12. Each positioning component 3 includes a positioning plate 31 hinged to the lower frame 2 and positioning blocks 32 fixed to the positioning plate 31. The positioning plate 31 is located on opposite sides of the corresponding positioning groove 22. The hinge axis of the positioning plate 31 is horizontal and located below the positioning groove 22. Several elastic elements 23 are fixed on the lower frame 2. The position and number of elastic elements 23 correspond one-to-one with the position and number of positioning plates 31. In this embodiment, the elastic element 23 is a torsion spring. The elastic element 23 pulls the positioning plate 31, causing the positioning plate 31 to rotate and cover the positioning groove 22. When the positioning plate 31 covers the positioning groove 22, the positioning blocks 32 are located above the positioning plate 31. When the positioning post 12 is inserted into the positioning groove 22, the positioning plates 31 located on opposite sides of the positioning groove 22 adhere to the sidewalls of the positioning post 12. The positioning post 12 has several positioning slots 121. The position and number of positioning slots 121 on the same positioning post 12 correspond one-to-one with the position and number of positioning blocks 32 located near the same positioning slot 22. When the positioning plate 31 is attached to the side wall of the positioning post 12, the positioning block 32 is engaged in the corresponding positioning slot 121 for positioning. This makes positioning the upper frame 1 and the lower frame 2 convenient.

[0027] See Figure 1 and Figure 3The upper frame 11 has sliding grooves 113, the position and number of which correspond one-to-one with the position and number of positioning posts 12. The vertical projection of the sliding grooves 113 is located on the positioning posts 12. The sliding grooves 113 are connected to the second positioning groove 121. A push block 4 is slidably connected to the positioning posts 12. The push block 4 is located in the sliding groove 113. The second sliding groove 113 is connected to the second positioning groove 121 located on the same positioning post 12. The second positioning groove 121 is located on the moving path of the push block 4. The push block 4 slides into or out of the second positioning groove 121. An elastic element 114 is fixed on the upper frame 11. In this embodiment, the elastic element 114 is a spring. The elastic element 114 abuts against the end face of the push block 4 near the second positioning groove 121, causing the push block 4 to tend to move away from the second positioning groove 121. When the push block 4 is only subjected to gravity and the force of the elastic element 114, the upper end face of the push block 4 is flush with the upper frame 11. The end of the positioning block 32 away from the positioning plate 31 is machined into an arc surface, and the arc surface protrudes in the direction away from the positioning plate 31. In this embodiment, the positioning block 32 is semi-circular. A driving element 5 is installed on the upper frame 11. The driving element 5 is a driving frame 51. Several protrusions 511 are machined on the driving frame 51. The position and number of the protrusions 511 correspond one-to-one with the position and number of the sliding grooves 113. The protrusions 511 are engaged with the corresponding sliding grooves 113, driving the corresponding push block 4 to move and extend into the positioning groove 121. The push block 4 abuts against the arc surface and continues to move towards the positioning groove 121, causing the positioning block 32 to move away from the positioning groove 121 and release the positioning. This makes it convenient to disassemble and install the upper frame 1 and the lower frame 2.

[0028] See Figure 1 and Figure 3 The upper frame 11 has a groove 115, and the groove 115 and the sliding groove 113 are spaced apart. The groove 115 is for the drive frame 51 to be inserted into. When the drive frame 51 is inserted into the groove 115.

[0029] See Figure 1 and Figure 3 An elastic pad 321 is fixed on the positioning block 32, and the elastic pad 321 covers the positioning block 32. When the positioning block 32 is engaged in the positioning groove 121, the positioning block 32 is positioned by pressing against the inner wall of the positioning groove 121 through the elastic pad 321. By setting the elastic pad 321, it is beneficial to reduce the wear between the positioning block 32 and the positioning post 12, and to increase the service life of the front frame of the car.

[0030] The implementation principle of a car front-end frame according to this application is as follows: the water tank is fixed by the upper frame 1 and the lower frame 2, which is more convenient than the traditional method of using screws to position the water tank and helps to improve the installation efficiency of the water tank.

[0031] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
