DETAILED DESCRIPTION

[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] One of the preferred embodiments of the present application is as follows: Figures 1 to 5 As shown, a mounting structure of a car door machine device includes a door machine back plate 2, a movable frame 3, an adjustment mechanism 4 and a (car door) door lintel 1, wherein the door machine back plate 2 is mounted on the movable frame 3, and the movable frame 3 is connected to the door lintel 1 through the adjustment mechanism 4.

[0025] It is understandable that after the door machine device (door machine back panel 2) is installed, if the position of the door machine device needs to be adjusted, the movable frame 3 can be adjusted by the adjustment mechanism 4, such as Figure 1 As shown, the height and (front-to-back) spacing of the movable frame 3 relative to the door lintel 1 can be adjusted under the action of the adjustment mechanism 4, so that the door machine device can be adjusted to a suitable installation position to ensure its normal operation and use. Such a design can improve the installation efficiency and accuracy of the door machine device, reduce the tediousness of manual adjustment, and ensure the stability and safety of the door machine device, thereby preventing vibration and noise caused by installation deviation during subsequent use.

[0026] One of the embodiments of the present application is as follows: Figure 3 As shown, the adjustment mechanism 4 includes a fixed frame 401 , a first adjustment device 402 and a second adjustment device 403 . The fixed frame 401 is installed at the door lintel 1 , and the movable frame 3 is connected to the fixed frame 401 through the first adjustment device 402 and the second adjustment device 403 .

[0027] It is understandable that if Figure 5 As shown, under the action of the first adjusting device 402, the height of the movable frame 3 relative to the fixed frame 401 can be adjusted, thereby realizing the up and down position adjustment of the door machine device; under the action of the second adjusting device 403, the front and rear spacing of the movable frame 3 relative to the fixed frame 401 can be adjusted, thereby realizing the front and rear distance adjustment of the door machine device.

[0028] As a further description of the above embodiment: Figure 3 and Figure 4 As shown, the first adjusting device 402 includes a first screw 4021 and a pair of first nuts 4022. The first screw 4021 is installed at the top or bottom of the mobile frame 3 and passes through the fixed frame 401. The first nuts 4022 cooperate with the first screw 4021 and are located on both sides of the fixed frame 401.

[0029] Specifically, a first waist hole 7 corresponding to the first screw rod 4021 is provided at the top or bottom end of the fixed frame 401. The first waist hole 7 is perpendicular to the side position of the lintel 1, and the first screw rod 4021 passes through the first waist hole 7, that is, the first screw rod 4021 can be moved and adjusted forward and backward and up and down along the first waist hole 7, and will not interfere with the forward and backward adjustment of the movable frame 3.

[0030] It should be known that when adjusting the door machine device up and down, the two first nuts 4022 are first loosened and moved away from the fixing frame 401, and then the first screw 4021 is moved up and down in the first waist hole 7 to achieve the height adjustment of the door machine device; when the door machine device is adjusted to a suitable height, the two first nuts 4022 are tightened so that the two first nuts 4022 are both against the fixing frame 401, thereby achieving the upper and lower position limit locking of the door machine device.

[0031] like Figure 3 and Figure 4 As shown, the second adjustment device 403 includes a second screw 4031 and a pair of second nuts 4032 . The second screw 4031 is installed on the side of the fixed frame 401 and passes through the movable frame 3 . The second nuts 4032 cooperate with the second screw 4031 and are located on both sides of the movable frame 3 .

[0032] Specifically, Figure 4As shown in the figure, a second waist-shaped hole 8 corresponding to the second screw 4031 is provided at the side position of the moving frame 3. The second waist-shaped hole 8 is perpendicular to the bottom position of the lintel 1, that is, the first waist-shaped hole 7 and the second waist-shaped hole 8 are perpendicular to each other. The second screw 4031 passes through the second waist-shaped hole 8, that is, the moving frame 3 can be adjusted up and down and back and forth relative to the second screw 4031 through the second waist-shaped hole 8, and thus will not interfere with the up and down adjustment of the moving frame 3.

[0033] It should be noted that when adjusting the door machine device back and forth, first loosen the two second nuts 4032 and move them away from the moving frame 3, and then adjust the distance between the door machine device and the lintel 1 by moving the second waist-shaped hole 8 on the moving frame 3 back and forth on the second screw 4031. When the door machine device is adjusted to an appropriate distance, tighten the two second nuts 4032 at this time, so that the two second nuts 4032 are both abutted against the two side positions of the moving frame 3, and the position limit locking of the door machine device back and forth can be achieved.

[0034] Based on the above embodiments, another embodiment of the present application is as Figure 1 and Figure 4 shown. Preferably, a pair (two groups) of first adjusting devices 402 and second adjusting devices 403 are provided. The first adjusting devices 402 are symmetrically installed at the top and bottom of the moving frame 3, and the second adjusting devices 403 are symmetrically installed at the upper and lower ends of the side of the fixed frame 401. It can be understood that due to the symmetrical design, the moving frame 3 will be more stable after adjustment and limitation, improving the stability and service life of the entire device.

[0035] Specifically, since two groups of second screws 4031 are provided and both penetrate the moving frame 3, the two groups of second screws 4031 have a limiting effect on the moving frame 3, so that the moving frame 3 can only be adjusted back and forth and up and down under the limiting effect of the second screws 4031. At the same time, with the limiting cooperation of the two groups of first screws 4021 and the fixed frame 401, the limiting stability of the moving frame 3 can be greatly improved.

[0036] In one embodiment of the present application, as Figure 4 shown, the moving frame 3 and the fixed frame 401 can both be designed in a "C" - shaped structure. Specifically, when processing the moving frame 3 and the fixed frame 401, a metal plate in a strip structure can be first (blanked) processed, and then the cut metal plate can be stamped and bent into a "C" - shaped structure. It can be seen that the structures of the moving frame 3 and the fixed frame 401 are simple and the processing is also convenient. Furthermore, it can adapt to mass production and has the advantages of low cost and high efficiency.

[0037] Based on the above embodiment, the movable frame 3 and the fixed frame 401 both include a vertical portion 4011 and a horizontal portion 4012 connected to both ends of the vertical portion 4011. When both are subjected to load force, bending and deformation may easily occur between the vertical portion 4011 and the horizontal portion 4012, thereby affecting the installation and use of the door machine device.

[0038] It should be known that, due to the installation limiting action of the four screws (a pair of first screws 4021 and a pair of second screws 4031), the movable frame 3 itself is not easy to deform; however, for the fixed frame 401, especially for the top position of the fixed frame 401, since its horizontal part 4012 is not supported and fixed, it is easy to deform under the action of a large load force.

[0039] Therefore, in order to solve the above technical problems, in one embodiment of the present application, Figure 3 As shown, a support portion 5 is installed between the horizontal portion 4012 and the vertical portion 4011 of the mobile frame 3. Specifically, the support portion 5 is a right-angled triangle structure, and the two right-angled sides of the support portion 5 can be welded and fixed to the horizontal portion 4012 and the vertical portion 4011 respectively, thereby increasing the strength of the mobile frame 3; it can be understood that when the fixed frame 401 is subjected to a load force, the support portion 5 can limit the deformation of the fixed frame 401, thereby improving stability.

[0040] Further, such as Figure 4 As shown, the support parts 5 are located on both sides of the fixed frame 401 and are symmetrically distributed, and an installation area 6 is formed between the corresponding support parts 5, and the mobile frame 3 is abutted against the installation area 6; it can be understood that the installation area 6 and the mobile frame 3 are adapted so that the mobile frame 3 can only be moved up and down and forward and backward in the installation area 6, further improving the stability of the mobile frame 3 limit.

[0041] The working principle of the utility model is:

[0042] First, a pair of fixed frames 401 are symmetrically installed at appropriate positions of the car door lintel 1, and then the door machine back plate 2 of the door machine device is installed on the mobile frame 3. In order to facilitate the adjustment work, we can first adjust the up and down position of the door machine device, that is, first loosen the two first nuts 4022 on the first screw 4021, and after adjusting the height of the door machine device, we can first screw the topmost first nut 4022 to a suitable position to overlap the top position of the fixed frame 401, that is, the mobile frame 3 is in a suspended state at this height position, and the remaining first nuts 4022 should not be tightened first, otherwise tightening will interfere with the front and rear adjustment of the door machine device. Then, the movable frame 3 is moved forward and backward along the second screw 4031. When it is adjusted to a suitable position, the two second nuts 4032 on the second screw 4031 are tightened to lock and limit the front and rear directions of the door machine device. Finally, the first nut 4022 that was not tightened before is tightened to lock and limit the up and down directions of the door machine device. In this way, the accurate installation of the door machine device is completed.

[0043] It should be noted that if Figure 3 and Figure 4 As shown, when the first nut 4022 is tightened, due to the squeezing and abutting fit between the first nut 4022 and the fixed frame 401, it can also play a role of limiting and locking the front and rear positions of the movable frame 3; similarly, when the second nut 4032 is tightened, due to the squeezing and abutting fit between the second nut 4032 and the movable frame 3, it can also play a role of limiting and locking the upper and lower positions of the movable frame 3.

[0044] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
