Detailed Implementation

[0028] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0029] The terminology of the door limiting device according to this application is described below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, a specific embodiment of this application provides a door limiting device, including a mounting base 100, a mounting bracket 200, and a movable latch 303. The mounting base 100 is used to be installed on the cab floor. The mounting bracket 200 is connected to the mounting base 100 and can extend and retract in multiple directions. The movable latch 303 is installed on the movable end of the mounting bracket 200 and forms a latching groove 305 for latching onto the cab door.

[0031] After powder coating the cab door and cab door frame, it is necessary to separate the cab door and cab door frame to avoid damaging the uncured powder coating on the cab door and cab door frame. However, it is also necessary to avoid excessive opening angle of the cab door on the production line. Therefore, the cab door needs to be fixed in a specific position to simultaneously achieve separation from the cab door frame and avoid excessive opening angle. Typically, positioning holes are provided on the cab floor plate for mounting the mounting base 100, and snap-fit ​​holes are formed on the cab door so that the snap-fit ​​groove 305 of the movable clip 303 can snap into the hole wall of the snap-fit ​​hole. However, the position of the positioning hole and the height of the snap-fit ​​hole are different for different product specifications. In this application, the movable clip 303 is mounted on the mounting bracket 200, which can extend and retract in multiple directions. By adjusting the extension direction and extension length of the mounting bracket 200, the movable clip 303 can be adapted to the positioning hole position and the height of the snap-fit ​​hole of different product specifications, thereby realizing the spraying limit of the cab door and the cab door frame, and thus improving the compatibility of the door limit device.

[0032] In some embodiments, the mounting bracket 200 includes a first bracket portion, a second bracket portion, and a third bracket portion. The first bracket portion is movablely engaged with the mounting base 100 along a first direction; the second bracket portion is movablely engaged with the first bracket portion along a second direction; and the third bracket portion is movablely engaged with the second bracket portion along a third direction. The movable clip 303 is mounted on the third bracket portion.

[0033] Specifically, the movable latch 303 can be adjusted in a first direction by moving the first bracket part and the mounting base 100 together; it can be adjusted in a second direction by moving the second bracket part and the first bracket part together; and it can be adjusted in a third direction by moving the third bracket part and the second bracket part together. This allows the movable latch 303 to be adjusted in multiple directions, thereby improving the adaptability of the door limiting device and making it suitable for more product specifications.

[0034] Specifically, the first direction is the transverse direction of the cab, the second direction is the longitudinal direction of the cab, and the third direction is the vertical direction of the cab, so as to achieve arbitrary adjustment of the movable card 303 within the cab space using the fewest number of components, thereby simplifying the door limiting device.

[0035] In some embodiments, the mounting base 100 has a first elongated through hole extending in a first direction. The first support portion includes a first locking pin and a lateral adjustment block 203. The first locking pin passes through the lateral adjustment block 203 and the mounting base 100 and can slide within the first elongated through hole. The lateral adjustment block 203 has a second elongated through hole extending in a second direction. The second support portion includes a second locking pin, a longitudinal adjustment block 204, and a vertical fixing block 202. The vertical fixing block 202 is mounted on the longitudinal adjustment block 204. The second locking pin passes through the longitudinal adjustment block 204 and the lateral adjustment block 203 and can slide within the second elongated through hole. The vertical fixing block 202 has a third elongated through hole extending in a third direction. The third support portion includes a third locking pin and a vertical adjustment block 201. The third locking pin passes through the vertical adjustment block 201 and the vertical fixing block 202 and can slide within the third elongated through hole. The movable latch 303 is mounted on the vertical adjustment block 201.

[0036] Specifically, the lateral adjustment block 203 can rotate relative to the mounting base 100 via the first locking pin to finely adjust the direction of the first elongated through hole on the lateral adjustment block 203; there are two second locking pins to improve the stability of the longitudinal adjustment block 204 moving within the second elongated through hole; and there are two third locking pins to improve the stability of the vertical adjustment block 201 moving within the third elongated through hole.

[0037] Furthermore, the mounting bracket 200 also includes locking nuts that are matched with the first locking pin, the second locking pin and the third locking pin, so as to fix the position after the position adjustment is completed, thereby improving the reliability of the door limiting device.

[0038] Those skilled in the art will understand that this application is not limited to the aforementioned movable engagement method of locking pin and elongated through hole, but may also include other structural forms that can achieve movable engagement, such as sliders and grooves. Other structural forms should also fall within the protection scope of this application.

[0039] In some embodiments, the movable latch 303 is rotatably connected to the vertical fixing block 202 to enable the movable latch 303 to engage and disengage from the cab door.

[0040] Specifically, when the movable latch 303 rotates toward the cab door, it can engage with the latching hole on the cab door; when the movable latch 303 rotates away from the cab door, it can disengage from the latching hole on the cab door.

[0041] Furthermore, the mounting bracket 200 is provided with a limiting rod 304 for limiting the rotation range of the movable clamp 303. The limiting rod 304 is located below the movable clamp 303 so that the movable clamp 303 can only rotate above the limiting rod 304, thereby realizing the specific position for the movable clamp 303 to engage and disengage from the cab door.

[0042] In some embodiments, when the movable latch 303 abuts against the limiting rod 304, the movable latch 303 is in a horizontal state. In other words, the rotation angle range of the movable latch 303 is 0° to 180°. It can be seen that simply flipping the movable latch 303 back and forth can achieve the engagement and disengagement with the cab door, which helps to improve the convenience of the door limiting device.

[0043] In some embodiments, one end of the movable latch 303 has a latching groove 305, and the other end is rotatably connected to the vertical adjustment block 201 through a movable lock 301. The movable latch 303 is fixed by locking the vertical adjustment block 201 and the movable latch 303 through the movable lock 301, and the movable latch 303 is rotatable by unlocking the vertical adjustment block 201 and the movable latch 303 through the movable lock 301, thereby improving the reliability and convenience of the door limiting device.

[0044] In some embodiments, the door limiting device further includes a support rod 302, which is mounted on the movable end of the mounting bracket 200 and used to abut against the cab door, so that there are multiple support points between the door limiting device and the cab door, thereby improving the stability of the cab door when painting the cab door.

[0045] In some embodiments, the support rod 302 is movably coupled to the mounting bracket 200 to adjust the extension length of the support rod 302, thereby adapting it to different product specifications and different working conditions.

[0046] Specifically, the different operating conditions refer to the painting operation and the transportation operation of the cab door. The cab door is in the open state when the painting operation is carried out and in the closed state when the transportation operation is carried out. Correspondingly, the end position of the support rod 302 also needs to be adjusted.

[0047] During transportation operations, the support rod 302 needs to be adjusted so as not to affect the closing of the cab door; during painting operations, especially when painting the outer surface of the cab door, the support rod 302 needs to abut against the inner side of the cab door and cooperate with the movable latch 303 to improve the stability of the cab door.

[0048] In some embodiments, the movable latch 303 has a plurality of latching grooves 305 arranged at intervals along its own length.

[0049] Specifically, at least two engaging grooves 305 are provided. The engaging groove 305 closer to the vertical adjustment block 201 is used to engage with the cab door in the closed state, and the engaging groove 305 farther away from the vertical adjustment block 201 is used to engage with the cab door in the open state. Furthermore, the distance between the two engaging grooves 305 is set according to the angle of rotation required for the cab door to switch from the closed state to the open state.

[0050] During the transportation of products on the production line, the cab door may need to be closed due to space width limitations. Before the painting operation, the door limiting device can be directly installed and the locking groove 305 of the movable clip 303 can be locked with the closed cab door to prevent the cab door from opening during transportation.

[0051] In some embodiments, the mounting base 100 includes a swing arm 102 and a base beam 104. A main positioning pin 103 is connected to the first end of the swing arm 102 and the first end of the base beam 104. An auxiliary positioning pin 101 is provided at the second end of the swing arm 102 and the second end of the base beam 104. A mounting bracket 200 is mounted on the base beam 104.

[0052] Specifically, the swing arm 102 and the base beam 104 intersect to determine the mounting plane of the mounting base 100. The mounting plane is parallel to the top surface of the cab floor, which helps to improve the stability of the mounting base 100.

[0053] Furthermore, the cab floor plate is provided with positioning holes for mounting the mounting base 100. The positioning holes are located in different positions for different product specifications. The positioning holes for different product specifications are adapted by adjusting the angle between the swing rod 102 and the base beam 104. At the same time, the main positioning pin 103 and the auxiliary positioning pin 101 are inserted into the positioning holes for fixation.

[0054] The specific usage method is as follows:

[0055] First, the main positioning pin 103 and the auxiliary positioning pin 101 are connected to the positioning holes on the cab floor to fix the mounting base 100 to the cab floor. Then, the mounting bracket 200 is adjusted and the movable clip 303 is rotated to engage with the closed cab door in a snap-fit ​​groove 305. Next, the cab door is transported on the production line. Then, the movable clip 303 is rotated to separate from the cab door in the snap-fit ​​groove 305, and the inner side of the cab door is painted. Then, the opening angle of the cab door is adjusted and the movable clip 303 is rotated to engage with the cab door in another snap-fit ​​groove 305. The support rod 302 is adjusted to abut against the inner side of the cab door to separate the cab door from the cab door frame and fix it in a fixed position. Finally, the outer side of the cab door is painted.

[0056] In a specific embodiment of this application, the door limiting device can effectively separate the driver's cab door from the driver's cab door frame and fix the driver's cab door during the spraying operation on the outer side of the driver's cab door, so as to avoid damaging the uncured powder coating on the driver's cab door. At the same time, the adjustable mounting base 100 and mounting bracket 200 can accommodate the usage requirements of various product specifications, thereby improving the compatibility of the door limiting device.
