The snap-fit ​​member is disposed on the slide rod, and the mating member is disposed on the connecting sleeve. The slide rod slides relative to the connecting sleeve to engage or disengage the snap-fit ​​member and the mating member.

[0007] Optionally, the mating component includes a first snap-fit ​​plate and an elastic pressure plate, the elastic pressure plate being pressed onto the first snap-fit ​​plate, and the snap-fit ​​component being configured to push open the elastic pressure plate along a first side of the first snap-fit ​​plate and move to the side where a second side of the first snap-fit ​​plate is located to snap into the mating component.

[0008] Optionally, the latching member includes a connecting rod, the first end of which is hinged to the second end of the slide rod, and the second end of the connecting rod is provided with a roller to move along the first side of the first latching plate to the side where the second side of the first latching plate is located.

[0009] Optionally, the first snap-fit ​​plate is in the form of a triangular plate, the triangular plate including opposing first side and second side and a bottom edge connected between the first side and the second side, the bottom edge being connected to the connecting sleeve.

[0010] Optionally, the elastic pressure plate includes a connecting plate and an elastic element, one end of the elastic element is fixedly connected to the connecting sleeve and the other end is fixedly connected to the connecting plate, and the connecting plate abuts against the first snap-fit ​​plate.

[0011] Optionally, the connecting plate is provided with a rocker plate on the side facing the snap-fit ​​member, and the rocker plate extends in a direction away from the first snap-fit ​​plate so that the rocker plate and the first side edge of the first snap-fit ​​plate form a flare.

[0012] Optionally, the end of the slide rod away from the connecting sleeve is connected to the second limiting assembly via the universal joint.

[0013] Optionally, the first limiting component includes a first limiting rod, which is used to connect with a connector for the rear floor of the vehicle. The connecting sleeve is provided with a positioning part, and the first limiting rod is rotatably connected to the positioning part.

[0014] The above technical solution utilizes a door limiting structure comprising a first limiting component, a second limiting component, and a connecting component connecting the first and second limiting components. During vehicle painting, the first limiting component is fixed to the vehicle floor, and the second limiting component is fixed to the vehicle door. The distance between the first and second limiting components is adjusted by the connecting component, allowing the door to be adjusted to an open state relative to the floor according to the painting conditions.

Detailed Implementation

[0021] The specific embodiments of this disclosure 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 disclosure.

[0022] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the outline of the part itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0023] In related technologies, during the automotive body painting process, some car models have a rearward tilt angle between the rear door hinge rotation axis and the ground, resulting in the rear door automatically closing after being opened. This requires manual repeated opening and closing of the door, making manual glue application or painting operations inconvenient and resulting in low painting efficiency.

[0024] To solve the above technical problems, such as Figure 1 and Figure 2 As shown, this disclosure provides a door limiting structure, including: a first limiting component 1, a second limiting component 2, and a connecting component 3. The first limiting component 1 is used for fixed connection with the floor of the vehicle; the second limiting component 2 is used for fixed connection with the door of the vehicle; the connecting component 3 connects the first limiting component 1 and the second limiting component 2, and the connecting component 3 is configured to adjust the distance between the first limiting component 1 and the second limiting component 2.

[0025] The above technical solution utilizes a door limiting structure comprising a first limiting component 1, a second limiting component 2, and a connecting component 3 that connects the first limiting component 1 and the second limiting component 2. During vehicle painting, the first limiting component 1 is fixed to the vehicle floor, and the second limiting component 2 is fixed to the vehicle door. The distance between the first limiting component 1 and the second limiting component 2 is adjusted by the connecting component 3, thereby allowing the door to be in an open state according to the painting conditions. The open door facilitates door painting or adhesive application by the workers, improving painting efficiency and quality.

[0026] To facilitate adjustment of the distance between the first limiting component 1 and the second limiting component 2, in some feasible embodiments, the connecting component 3 includes a locking component 4, a connecting sleeve 31, and a slide rod 32 slidably connected to the connecting sleeve 31. The slide rod 32 is connected to the first limiting component 1, and the connecting sleeve 31 is connected to the second limiting component 2. The locking component 4 is configured to lock or unlock the slide rod 32 and the connecting sleeve 31 as they slide relative to each other. The cross-section of the connecting sleeve 31 can be square, meaning the connecting sleeve 31 can be constructed as a square sleeve. The cross-section of the sliding rod 32 is adapted to the connecting sleeve 31, meaning the sliding rod 32 can also be constructed as a square tube. The square tube can be slidably inserted into the square sleeve. The sliding rod 32 is connected to the first limiting component 1, and the connecting sleeve 31 is connected to the second limiting component 2. When the car door needs to open relative to the floor, the first limiting component 1 is fixedly connected to the car door, and the second limiting component 2 is fixedly connected to the car floor. Pulling the car door causes the sliding rod 32 to slide, changing the relative position of the sliding rod 32 and the connecting sleeve 31, thereby increasing the distance between the first limiting component 1 and the second limiting component 2. When the sliding rod 32 slides to the preset position, the locking component 4 locks the sliding rod 32 and the connecting sleeve 31. At this time, the car door can be in an open state relative to the floor, which is convenient for workers to spray the car door, improving spraying efficiency and spraying quality. After the painting is completed, the locking assembly 4 can be unlocked by pushing the door in the opposite direction, causing the sliding rod 32 and the connecting sleeve 31 to slide in the opposite direction relative to the connecting sleeve 31 under the action of gravity until the door is closed.

[0027] It is understandable that the car door is in an open state relative to the floor. The opening and closing angle of the car door relative to the floor can be adjusted by adjusting the relative position of the slide rod 32 and the connecting sleeve 31 in the adjusting connecting assembly 3. For example, the opening and closing angle of the car door relative to the floor can be controlled to vary from 0 to 5°.

[0028] It is understood that the above-described structure of the connecting sleeve 31 as a square sleeve and the slide rod 32 as a square tube is illustrative. In other embodiments, the connecting sleeve 31 can also be constructed as a circular sleeve and the slide rod 32 can also be adapted to be constructed as a circular tube. In addition, in order to make the slide rod 32 more stable when supported, the slide rod 32 can be constructed as solid steel, thereby improving the structural strength of the slide rod 32 and preventing deformation of the slide rod 32 when supported in the open state of the car door.

[0029] In some feasible embodiments, the first limiting assembly 1 includes a first limiting rod 11, which is used to connect with a connector on the rear floor of the vehicle. The first limiting rod 11 is constructed as a threaded rod, and the bottom end of the first limiting rod 11 is provided with threads. The first limiting rod 11 is connected to the connector on the rear floor of the vehicle. The connector can be a nut welded to the rear floor. The first limiting rod 11 is fixed to the rear floor through a threaded connection. The connecting sleeve 31 is provided with a positioning part 33. The first limiting rod 11 is rotatably connected to the positioning part 33. The positioning part 33 can be a stepped positioning hole. The middle part of the first limiting rod 11 is provided with a boss that mates with the positioning hole, so that when the connecting sleeve 31 is sleeved with the first limiting rod 11, the first limiting rod 11 can be rotatably connected to the connecting sleeve 31.

[0030] In some feasible embodiments, a handle is provided at the top of the first limiting rod 11 to facilitate twisting the first limiting rod 11. The handle can be detachably connected to the first limiting rod 11. Thus, when the first limiting rod 11 needs to be fixedly connected to the rear floor of the vehicle, the handle can be installed, and the first limiting rod 11 can be fixed to the rear floor of the vehicle by rotating the handle. When the connecting sleeve 31 needs to be fitted onto the first limiting rod 11, the handle can be selectively removed to facilitate the fitting of the connecting sleeve 31 onto the first limiting rod 11.

[0031] In some feasible embodiments, the second limiting assembly 2 includes a second snap-fit ​​plate 21, which includes a snap-fit ​​groove 22 that mates with the vehicle door. The second snap-fit ​​plate 21 is provided with a locking member 23 for fixing the second snap-fit ​​plate 21 to the vehicle door. The second snap-fit ​​plate 21 can be a U-shaped plate with the snap-fit ​​groove 22 formed at its opening. The snap-fit ​​groove 22 can engage with the lower sheet metal edge of the audio mounting hole in the inner door panel. The locking member 23 can be a locking bolt. The outer wall of the U-shaped plate has a screw hole that mates with the locking bolt. After the snap-fit ​​groove 22 engages with the lower sheet metal edge of the audio mounting hole in the inner door panel, the second snap-fit ​​plate 21 is fixedly connected to the vehicle door by rotating the locking bolt. The end of the slide rod 32 furthest from the connecting sleeve 31 is connected to the second limiting assembly 2 via a universal joint 7. The universal joint 7 can be a ball joint structure or a universal joint structure. In this embodiment, in order to enable the slide rod 32 to rotate relative to the second limiting component 2, the universal joint 7 can be a ball joint structure. The movable part of the ball joint structure can be connected to the end of the slide rod 32 away from the connecting sleeve 31. The fixed part of the ball joint structure can be fixedly connected to the second locking plate 21 through a connecting rod. Thus, the slide rod 32 and the second locking plate 21 are connected through the ball joint structure, and the infinite angle change of the ball joint structure can adapt to the torsion between the slide rod 32 and the second locking plate 21 when the door is opened.

[0032] In addition, a positioning post 24 is provided on the second snap plate 21. The positioning post 24 can be inserted into the mounting hole on the door so that the snap groove 22 is more stably snapped into the lower sheet metal edge of the audio mounting hole on the inner panel of the door.

[0033] Of course, the slide bar 32 may include a first slide bar 34 and a second slide bar 35, wherein the first slide bar 34 and the second slide bar 35 are detachably connected. For example, the first slide bar 34 and the second slide bar 35 may be threaded together, so that changing the length of the first slide bar 34 and the second slide bar 35 can change the overall length of the slide bar 32, thereby improving the versatility of the slide bar 32 to adapt to the range of opening and closing angles of the car door and the car body. In addition, the first slide bar 34 and the second slide bar 35 may be solid square steel and / or round steel. For example, in this embodiment, the cross-section of the connecting sleeve 31 is square, the second slide bar 35 passes through the connecting sleeve 31, the second slide bar 35 may be adapted to be solid square steel, and the first slide bar 34 may be solid round steel. By making the cross-section of the first slide bar 34 smaller than the cross-section of the second slide bar 35, the overall weight of the slide bar 32 can be reduced.

[0034] To facilitate the unlocking of the locking assembly 4, the sliding rod 32 and the connecting sleeve 31, in some feasible embodiments, the locking assembly 4 includes a snap-fit ​​element 5 and a mating element 6. The snap-fit ​​element 5 is disposed on the sliding rod 32, and the mating element 6 is disposed on the connecting sleeve 31. The sliding rod 32 and the connecting sleeve 31 slide relative to each other to engage or disengage the snap-fit ​​element 5 and the mating element 6. When the car door is opened, pulling the car door forward causes the sliding rod 32 and the connecting sleeve 31 to slide relative to each other to a preset position, at which point the snap-fit ​​element 5 and the mating element 6 engage. At this time, the car door is in an open state supported by the sliding rod 32, and the open car door facilitates the application of adhesive or painting by the workers. When the application of adhesive or painting is completed and the car door is closed, simply push the car door in the opposite direction to disengage the snap-fit ​​element 5 and the mating element 6. The sliding rod 32 will slide in the opposite direction under the weight of the car door, and the sliding rod 32 will return to its initial position. At this time, the car door is closed.

[0035] The mating component 6 may include a first snap-fit ​​plate 61 and an elastic pressure plate 62. The elastic pressure plate 62 is pressed against the first snap-fit ​​plate 61. The snap-fit ​​component 5 is configured to push open the elastic pressure plate 62 along the first side of the first snap-fit ​​plate 61 and move to the side where the second side of the first snap-fit ​​plate 61 is located to snap into the mating component 6. For example, the first snap-fit ​​plate 61 is a triangular plate. The triangular plate includes opposing first and second sides and a bottom edge connecting the first and second sides. The bottom edge is connected to the connecting sleeve 31. The elastic pressure plate 62 is pressed against the apex of the triangular plate. When the car door is opened, the car door is pulled, and the sliding rod 32 slides relative to the connecting sleeve 31 to a preset position. At this time, the snap-fit ​​component 5 can push open the elastic pressure plate 62 along the first side of the triangular plate and move to the side where the second side of the triangular plate is located. When the external force on the car door is removed, the snap-fit ​​component 5 will abut against the elastic pressure plate 62 and the second side of the triangular plate to achieve snap-fit ​​between the snap-fit ​​component 5 and the mating component 6. When the car door is closed, push the car door in the opposite direction. Due to the presence of external force, the latch 5 moves in the opposite direction from the second side of the triangular plate and pushes the elastic pressure plate 62 to the side where the first side of the triangular plate is located. At this time, the latch 5 and the mating part 6 are unlocked. After unlocking, the slide bar 32 slides in the opposite direction with the gravity of the car door to return to the initial position. At this time, the car door is closed.

[0036] It is understood that the above-described first snap-fit ​​plate 61 is constructed as a triangular plate, which is illustrative. In other embodiments, the first snap-fit ​​plate 61 can also be constructed as other structures. For example, the first snap-fit ​​plate 61 can also be constructed as an arc-shaped plate or an arc-shaped protrusion.

[0037] In some feasible embodiments, the elastic pressure plate 62 may include a connecting plate 63 and an elastic element 64. The connecting plate 63 may be a strip plate, and the elastic element 64 may be a compression spring. One end of the compression spring is fixedly connected to the connecting sleeve 31, and the other end is fixedly connected to the first end of the connecting plate 63. The portion of the connecting plate 63 away from the first end abuts against the first snap-fit ​​plate 61. Thus, the compression spring allows the portion of the connecting plate 63 away from the first end to form a downward pressure and abut against the first snap-fit ​​plate 61. When the car door is opened and pulled, the sliding rod 32 and the connecting sleeve 31 slide relative to each other to a preset position. At this time, the snap-fit ​​member 5 can push open the connecting plate 63 along the first side of the triangular plate and move to the side where the second side of the triangular plate is located. When the external force on the car door is removed, the snap-fit ​​member 5 will abut against the connecting plate 63 and the second side of the triangular plate to achieve snap-fit ​​between the snap-fit ​​member 5 and the mating member 6.

[0038] In addition, in order to facilitate the snap-fit ​​5 to contact the connecting plate 63 along the first side of the triangular plate, a rocker plate 65 is provided on the side of the connecting plate 63 facing the snap-fit ​​5. The rocker plate 65 extends away from the first snap-fit ​​plate 61 so that the rocker plate 65 and the first side of the first snap-fit ​​plate 61 form a flare. The flare makes it easier for the snap-fit ​​5 to contact the rocker plate 65 later when it moves along the first side of the triangular plate, so that the snap-fit ​​5 can push the connecting plate 63 open along the first side of the triangular plate with less effort.

[0039] To facilitate the engagement or disengagement of the snap-fit ​​element 5 and the mating element 6, in some feasible embodiments, the snap-fit ​​element 5 includes a connecting rod 51, the first end of which is hinged to the second end of the slide rod 32, and the second end of the connecting rod 51 is provided with a roller 52 to move along the first side of the first snap-fit ​​plate 61 to the side where the second side of the first snap-fit ​​plate 61 is located. The first end of the connecting rod 51 can be provided with a hinge shaft, which is hinged to the second end of the slide rod 32. The second end of the connecting rod 51 can be provided with a roller shaft, on which a roller 52 is provided. The roller 52 will contact the slide rod 32 due to its own weight. When the door needs to be opened, the door is pulled, and the slide rod 32 slides relative to the connecting sleeve 31, causing the roller 52 to gradually contact the first side of the first snap-fit ​​plate 61 and push open the connecting plate 63, moving to the side where the second side of the triangular plate is located. When the pulling force of the door is released, the roller 52 abuts against the second side of the first snap-fit ​​plate 61 and the connecting plate 63, so that the snap-fit ​​part 5 and the mating part 6 are snapped together. When the car door is closed, push the car door in the opposite direction. Due to the presence of external force, the roller 52 moves in the opposite direction from the second side of the triangle plate and pushes the connecting plate 63 to the side where the first side of the triangle plate is located. At this time, the snap-fit ​​part 5 and the mating part 6 disengage and unlock. After unlocking, the slide bar 32 slides in the opposite direction with the gravity of the car door and returns to its initial position. At this time, the car door is closed.
