DETAILED DESCRIPTION

[0031] The core of the present invention is to disclose an upper skirt plate device to achieve rapid disassembly and assembly and reduce maintenance costs.

[0032] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the invention as set forth in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not necessarily required to serve as solutions to the invention as set forth in the claims.

[0033] Combine Figure 1 and Figure 2 The upper skirt panel device disclosed in the embodiment of the present invention includes a fixed skirt panel 100 and a movable skirt panel 200. The fixed skirt panel 100 is used to be fixed to the vehicle body 300 and is provided with a snap-in slot 111 for snapping in with the movable skirt panel 200. The snap-in slot 111 has a snap-in interface.

[0034] The movable skirt panel 200 includes a skirt panel body 203 and a snap-fit connector. The snap-fit connector is disposed at one end of the skirt panel body 203 and is configured to extend from a snap-fit interface into a snap-fit slot 111, thereby snapping the fixed skirt panel 100 into the movable skirt panel 200. To prevent the snap-fit connector from falling out of the snap-fit slot 111, the size of the snap-fit connector needs to be larger than the size of the snap-fit interface. When snapping the snap-fit connector from the snap-fit interface into the snap-fit slot 111, the snap-fit connector needs to be tilted so that it can easily pass through the snap-fit interface and enter the snap-fit slot 111. After entering the snap-fit slot 111, the snap-fit connector can be restored to its installed state and cannot fall out of the snap-fit interface.

[0035] When removing the movable skirt panel 200, a similar operation as for installation is required, that is, the snap joint is tilted so that one end of the snap joint first extends out of the snap interface, and then the entire snap joint extends out of the snap interface, thereby achieving rapid removal of the fixed skirt panel 100 and the movable skirt panel 200. The snap joint is arranged in the snap slot 111, which makes the installation between the fixed skirt panel 100 and the movable skirt panel 200 have a layered feel and a high-quality appearance.

[0036] Compared with the prior art, the fixed skirt plate 100 and the movable skirt plate 200 of the upper skirt plate device disclosed in the embodiment of the present invention can be quickly disassembled and assembled, reducing maintenance costs, and have a simple structure, which is convenient for daily maintenance and regular inspection and maintenance.

[0037] In order to achieve the quick disassembly and assembly of the fixed skirt plate 100 and the movable skirt plate 200, the fixed skirt plate 100 includes a clamping profile member 110 for clamping with the movable skirt plate 200 and a connecting profile member 120 for connecting with the vehicle body. The clamping profile member 110 includes a first clamping wall 112 and a second clamping wall 113 for clamping with the clamping joint. Between the first clamping wall 112 and the second clamping wall 113 is a clamping port, and a clamping groove 111 is provided on the clamping profile member 110. The first clamping wall 112 and the second clamping wall 113 form the side walls of the clamping groove 111 close to the clamping port, while the side wall of the clamping groove 111 far from the clamping port is defined as the mounting wall, and the connecting profile member 120 is arranged on the clamping profile member 110 (i.e., on the mounting wall) for fixing with the vehicle body 300. As Figure 6 shown, the connecting profile member 120 can be fastened to the vehicle body 300 by bolts.

[0038] It should be noted that the space of the clamping groove 111 should ensure that the clamping joint can deflect at a certain angle inside to facilitate disassembly and assembly, that is, the size of the clamping port can ensure that the clamping joint can be disengaged when rotated to a certain angle; under the normal installation angle of the movable skirt plate 200, the clamping joint cannot be disengaged through the clamping port.

[0039] In order to facilitate the clamping joint to extend from the clamping port into the clamping groove 111 and be clamped with the first clamping wall 112 and the second clamping wall 113, the length of the clamping joint is less than the length of the clamping groove 111 and greater than the length of the clamping port, so that when the clamping joint enters the clamping groove 111 from the clamping port, the clamping groove 111 can accommodate the clamping joint. Although the size of the clamping port is smaller than the size of the clamping joint, due to the certain depth of the clamping groove 111, when installing the clamping joint, the depth of the clamping groove 111 can be utilized, so that after the clamping joint deflects at a certain angle, it can extend into the clamping groove 111.

[0040] Furthermore, in order to better realize the clamping function of the clamping joint, the clamping joint includes a first clamping part 201 for abutting against the first clamping wall 112 and a second clamping part 202 for abutting against the second clamping wall 113. The length of the second clamping part 202 is less than the length of the clamping port, so that the second clamping part 202 can extend from the clamping port into the clamping groove 111, and the space length of the clamping groove 111 above the clamping port is greater than the length of the first clamping part 201 for temporarily accommodating the first clamping part 201 when installing the clamping joint.

[0041] As Figure 7 shown, when installing the movable skirt plate 200 onto the fixed skirt plate 100, first extend the first clamping part 201 from the clamping port into the space of the clamping groove 111 above the clamping port until the connection between the skirt plate body 203 and the first clamping part 201 interferes with the first clamping wall 112 and cannot be pushed further.

[0042] As Figure 8 shown, after the connection between the first clamping portion 201 and the skirt body 203 abuts against the first clamping stop wall 112, the skirt body 203 is rotated with the abutting portion between the second clamping portion 202 and the skirt body 203 as the center point, thereby driving the clamping joint to rotate until the second clamping portion 202 enters the clamping groove 111 through the clamping port.

[0043] As Figure 9 shown, after the entire clamping joint enters the clamping groove 111, the skirt body 203 is pulled downward, and the entire installation process is completed. The removal of the movable skirt 200 and the fixed skirt 100 is the reverse process of the above, which will not be elaborated here.

[0044] The second clamping portion 202 and the skirt body 203 form a positioning groove for positioning with the second clamping stop wall 113. After both the first clamping portion 201 and the second clamping portion 202 enter the clamping groove 111, the movable skirt 200 can move downward under the action of its own weight (or manual operation by the operator) until the second clamping stop wall 113 is embedded in the positioning groove. At this time, the first clamping portion 201 abuts against the inner wall of the first clamping stop wall 112, and the fixed skirt 100 and the movable skirt 200 are clamped to form a fixation.

[0045] In order to reduce the impact caused by the collision between the fixed skirt 100 and the movable skirt 200 during the disassembly and assembly process, a buffer layer is provided on the surface of the positioning groove to buffer the movement between the positioning groove and the second clamping stop wall 113. A protective layer for buffering with the groove wall of the clamping groove 111 is provided at the end of the first clamping portion 201 to buffer the movement of the first clamping portion 201 in the clamping groove 111. The buffer layer and the protective layer can be of the same material or different materials, as long as they are materials with buffer functions.

[0046] As Figure 2 and Figure 3 shown, a hanging plate 114 is provided on the clamping profile member 110, and a hanging groove for hanging with the vehicle body 300 is formed between the hanging plate 114 and the clamping profile member 110. In a specific embodiment disclosed in the present invention, the hanging groove is used to hang on the eaves of the vehicle body 300 to increase the connection reliability between the upper skirt device and the vehicle body 300.

[0047] Furthermore, in order to enhance the structural strength of the movable skirt 200, reinforcing ribs are provided on the surface of the skirt body 203 close to the vehicle body 300. It should be noted that the reinforcing ribs can also be provided on the surface of the skirt body 203 far from the vehicle body 300, or on both surfaces of the skirt body 203. The solution of setting on the surface close to the vehicle body 300 can avoid the exposure of the reinforcing rib structure, improve the appearance quality of the upper skirt device, and match the appearance of the whole vehicle to improve the vehicle quality.

[0048] Combined with Figure 4 and Figure 5 , in order to further enhance the reliability of the connection between the upper skirt plate device and the vehicle body 300, an installation part for fixing to the vehicle body 300 is provided at one end of the skirt plate body 203 away from the fixed skirt plate 100. The installation part can be connected to the vehicle body 300 through bolts, and compared with the prior art, the bolts can directly connect to the vehicle body 300 from the inside of the installation part (as shown in Figure 4 ), avoiding the exposure of the connection structure and improving the appearance quality. It should be noted that the heads of the bolts can also be exposed outside the skirt plate body 203 (as shown in Figure 5 ).

[0049] The terms "first" and "second" etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the steps or units listed, but may include steps or units not listed.

[0050] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
