DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The following will be combined with Figures 1-5 to give a detailed description of an installation bracket installed under an automotive electric tailgate according to an embodiment of the present utility model.

[0023] Embodiment:

[0024] An installation bracket installed under an automotive electric tailgate provided by an embodiment of the present utility model, as shown in reference to Figures 1 to 5 includes an installation bracket 1. A ball head seat 2 is welded on the installation bracket 1. A connecting ball head 3 for an automotive electric tailgate push rod is detachably installed at the end of the ball head seat 2. With this structure, the installation bracket 1 is installed on the vehicle body, and then the connecting ball head 3 on the ball head seat 2 is connected to the electric push rod, thereby realizing the installation of the electric push rod and playing a role in supporting the opened electric tailgate later.

[0025] As shown in reference to Figures 1 to 5 a threaded hole 4 is opened on the connecting ball head 3. A connecting bolt 5 is in threaded connection with the threaded hole 4. A cavity 6 is opened at the bottom of the ball head seat 2, and a through hole 7 is opened at the bottom of the cavity 6. The connecting bolt 5 penetrates through the through hole 7. With this structure, the connecting bolt 5 extends into the cavity 6 of the ball head seat 2 and penetrates through the through hole 7 on the ball head seat 2 to be connected to the threaded hole 4 of the connecting ball head 3, thereby installing the connecting ball head 3 on the ball head seat 2. Later, when the connecting ball head 3 is severely worn, the operator can directly remove the connecting bolt 5 to remove the connecting ball head 3, so that only the worn ball head 3 needs to be replaced, and there is no need to replace the entire installation bracket 1, which is convenient for later maintenance and reduces the maintenance cost at the same time.

[0026] As shown in reference to Figures 1 to 5 the installation bracket 1 is of an L-shaped structure.

[0027] As shown in reference to Figures 1 to 5 two fixing holes 8 are opened on the installation bracket 1. With this structure, the fixing holes 8 are used to connect with the threaded holes reserved on the vehicle body.

[0028] As shown in reference to Figures 1 to 5As shown in the figure, a jack 9 is provided on the mounting bracket 1. The ball head seat 2 is fitted through the jack 9. A bottom plate 10 is constructed at the bottom of the ball head seat 2. The bottom plate 10 is welded to the mounting bracket 1. The inner periphery of the ball head seat 2 is welded to the mounting bracket 1. This structure of welding the bottom plate 10 to the mounting bracket 1 and the inner side of the ball head seat 2 to the mounting bracket ensures the connection strength of the ball head seat 2 and also ensures the bearing capacity. Moreover, the ball head seat 2 passes through the jack 9, and the position of the ball head seat 2 is limited by the jack 9, while improving the shear resistance of the ball head seat 2.

[0029] Reference Figures 1 to 5 As shown in the figure, a convex seat 11 is constructed on the connecting ball head 3. A limiting strip 12 is constructed on the outer wall of the convex seat 11. A clamping groove 13 is provided at the top of the ball head seat 2. The clamping groove 13 is fitted and clamped with the convex seat 11. A limiting groove 14 is provided on the inner wall of the clamping groove 13. The limiting groove 14 is fitted and clamped with the limiting strip 12. This structure of the limiting strip 12 on the convex seat 11 being clamped with the limiting groove 14 in the clamping groove 13 can limit the connection position between the connecting ball head 3 and the ball head seat 2, thus preventing the connecting ball head 3 from rotating during use and causing the connecting ball head 3 to fall off, and improving the connection stability.

[0030] The implementation principle of an automotive electric tailgate lower mounting bracket in an embodiment of the present application is as follows: The mounting bracket 1 is connected to the vehicle body. Then, the connecting bolt 5 is inserted into the cavity 6 of the ball head seat 2 and passes through the through hole 7 on the ball head seat 2 to be connected to the threaded hole 4 of the connecting ball head 3, thereby installing the connecting ball head 3 on the ball head seat 2. In the later stage, when the connecting ball head 3 is severely worn, the operator can directly remove the connecting bolt 5 to remove the connecting ball head 3. Thus, only the worn ball head 3 needs to be replaced, and there is no need to replace the entire mounting bracket 1, which is convenient for later maintenance and reduces the maintenance cost at the same time.

[0031] Moreover, the ball head seat 2 passes through the jack 9 on the mounting bracket 1. The position of the ball head seat 2 is limited by the jack 9, while improving the shear resistance of the ball head seat 2. The welding connection between the bottom plate 10 and the mounting bracket 1 and the welding of the inner side of the ball head seat 2 to the mounting bracket ensure the connection strength of the ball head seat 2 and also ensure the bearing capacity.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
