[0022] Please see Figures 1 to 3The frameless door glass assembly structure 100 of the embodiment of the present application comprises a guide rail 10, a sliding block 20 and a glass clamping device 30. The guide rail 10 is used to be mounted on a door frame. The sliding block 20 is slidingly mounted on the guide rail 10. The glass clamping device 30 is assembled on the sliding block 20, and the sliding block 20 can drive the glass clamping device 30 to slide up and down along the guide rail 10, so as to realize the lifting of the door glass 40.
[0023] The glass clamping device 30 comprises a clamping piece 31 and a fixing piece 32. In an embodiment, the material of the clamping piece 31 is plastic, and the material of the fixing piece 32 is metal, but is not limited thereto.
[0024] The clamping piece 31 comprises a first clamping arm 311 and a second clamping arm 312 for clamping and fixing the door glass 40. The first clamping arm 311 is attached to the sliding block 20, and the fixing piece 32 is assembled on the second clamping arm 312. One of the first clamping arm 311 and the second clamping arm 312 is provided with a limiting sleeve 3111 and an interference rib 3112 protruding radially outward from the limiting sleeve 3111. The door glass 40 is sleeved on the limiting sleeve 3111 through a mounting hole 41, and the door glass 40 is interference-fitted with the interference rib 3112. The clamping piece 31 comprises a first through hole 3113 penetrating the limiting sleeve 3111. The sliding block 20 comprises a second through hole 21 corresponding to the first through hole 3113. The fixing piece 32 comprises a threaded hole 321 corresponding to the first through hole 3113. A threaded member 50 penetrates the second through hole 21 and the first through hole 3113 in sequence and is locked with the threaded hole 321. The threaded member 50 can be a bolt or a screw.
[0025] During assembly, the fixing piece 32 is assembled on the second clamping arm 312, then the door glass 40 is sleeved on the limiting sleeve 3111, and the door glass 40 is clamped and fixed by the first clamping arm 311 and the second clamping arm 312. In this way, the door glass 40 is mounted on the glass clamping device 30. Then, the glass clamping device 30 with the door glass 40 is mounted on the sliding block 20. Finally, the threaded member 50 penetrates the second through hole 21 and the first through hole 3113 and is locked with the threaded hole 321. In this way, the assembly of the door glass 40 can be completed without using special equipment, which can reduce the development cost of the whole vehicle. In addition, since the limiting sleeve 3111 is provided with the interference rib 3112, the door glass 40 is interference-fitted with the interference rib 3112, so that the door glass 40 can be reliably positioned, and the door glass 40 is prevented from moving relative to the clamping piece 31.
[0026] Preferably, the interference rib 3112 has a height of 0mm to 0.5mm and a width of 0mm to 0.2mm. In this way, the interference rib 3112 has better strength, so that the position limiting of the door glass 40 is more reliable. In some embodiments, the height of the interference rib 3112 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm or any value between any two adjacent values. The width of the interference rib 3112 can be 0.1mm, 0.2mm or any value between any two adjacent values.
[0027] The number of the interference rib 3112 is 2 or more. In this way, the interference rib 3112 can more reliably position the door glass 40. In the illustrated embodiment, the number of the interference rib 3112 is set to 4, but is not limited thereto.
[0028] In one embodiment, the first clamping arm 311 is provided with the position limiting sleeve 3111, and the second clamping arm 312 is provided with the clamping hook 3121 which is engaged with the position limiting sleeve 3111. Specifically, the position limiting sleeve 3111 extends from the first clamping arm 311 towards the second clamping arm 312, and the position limiting sleeve 3111 includes the clamping portion 3114 which cooperates with the clamping hook 3121. In another embodiment, the second clamping arm 312 is provided with the position limiting sleeve 3111, and the first clamping arm 311 is provided with the clamping hook 3121 which is engaged with the position limiting sleeve 3111.
[0029] In the illustrated embodiment, the second clamping arm 312 is provided with the clamping jaw 3122 for mounting the fixing member 32. By limiting the fixing member 32 with the clamping jaw 3122, the fixing member 32 can be conveniently mounted on the second clamping arm 312. The clamping jaw 3122 is arranged at the edge of the second clamping arm 312.
[0030] In the illustrated embodiment, the first clamping arm 311 includes a plurality of first protrusions 3113 which abut against the door glass 40, and the second clamping arm 312 includes a plurality of second protrusions 3123 which abut against the door glass 40. By abutting the first protrusions 3113 and the second protrusions 3123 against the two sides of the door glass 40 respectively, the door glass 40 can be more stably clamped, so that the door glass 40 is prevented from shaking between the first clamping arm 311 and the second clamping arm 312.
[0031] In the illustrated embodiment, the sliding block 20 includes the first guide structure 25, and the clamping member 31 is provided with the second guide structure 315 which cooperates with the first guide structure 25. By cooperating the first guide structure 25 and the second guide structure 315, the glass clamping device 30 for mounting the door glass 40 can be conveniently and quickly mounted on the sliding block 20.
[0032] The clamping member 31 comprises a hinge portion 319 connecting the first clamping arm 311 and the second clamping arm 312. That is, the first clamping arm 311 and the second clamping arm 312 can rotate relative to each other. After the door glass 40 is sleeved on the limiting sleeve 3111, the door glass 40 can be clamped by rotating the first clamping arm 311 or the second clamping arm 312.
[0033] The embodiment of the present application provides a frameless door, which comprises the frameless door glass assembly structure 100.
[0034] The embodiment of the present application provides an automobile, which comprises the frameless door.
[0035] The above merely describes the preferred embodiment of the present application, but should not be used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
