Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door stoppers, in particular to a stopper for assisting in closing a waterproof vehicle door. Background Art

[0002] The function of the door limiter is to limit the degree of opening of the waterproof door. On the one hand, it can limit the maximum opening of the door to prevent the door from opening too wide. On the other hand, it can keep the door open when needed. For example, when the car is parked on a slope or when there is a normal wind, the door will not close automatically. Common door opening limiters are separate pull-strap limiters. Some limiters are also made into one piece with the door hinge. They usually have a limiting function when the waterproof door is fully open or half open.

[0003] Existing limiters used on waterproof car doors generally limit the position of the opened waterproof car door by setting two sets of pressure blocks and cooperating with elastic components, such as springs. However, after long-term use, the elastic components are prone to fatigue and insufficient elasticity. The number of elastic components provided is relatively small, resulting in poor limiting effect on the waterproof car door. In addition, the waterproof car door has more waterproof components than ordinary waterproof doors and is heavier. The limiter on it cannot effectively assist the user in closing the waterproof car door, resulting in more effort for the user to close the waterproof car door. Therefore, the present invention proposes a limiter for assisting in closing the waterproof car door of a car. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 4 , a limiter for helping to close a waterproof door of a car, includes a limiter connecting arm 1 and a door panel module 2, several groups of arc-shaped connecting blocks 6 are fixedly installed on the upper and lower surfaces of the limiter connecting arm 1, a fixed shell 3 is sleeved on the outside of the limiter connecting arm 1 near one end, the outer wall of the fixed shell 3 and a circular rubber pad 23 is fixedly connected to the outer position of the limiter connecting arm 1, the limiter connecting arm 1 is fixedly installed with a connecting head 7 near one end of the fixed shell 3, and the other end is rotatably connected to a hinge block 5, a limiting mechanism 20 is arranged inside the fixed shell 3, and an auxiliary mechanism 21 is arranged on the outer wall of the door panel module 2, the limiting mechanism 20 includes two groups of fixed plates 8 and two groups of telescopic links 13, the two groups of fixed plates 8 are fixedly installed inside the fixed shell 3 and located on both sides of the limiter connecting arm 1, the two groups of telescopic links 13 are fixedly connected to the upper and lower inner wall positions of the fixed shell 3, and the outside of the two groups of telescopic links 13 are both sleeved with a support spring 1.

[0025] The movable ends of the two sets of telescopic connecting rods 13 are fixedly connected to the limiting blocks 14, and the outer walls of the two sets of fixed plates 8 are penetrated by two sets of vertical slots 10. The inside of the two sets of vertical slots 10 are fixedly installed with sliding rods 11, and the outside of the two sets of sliding rods 11 are sleeved with sliders 12. The outside of the sliding rods 11 and the position between the outer wall of the slider 12 and the inner wall of the vertical slot 10 are sleeved with supporting springs 2. The two sets of fixed plates 8 are fixedly installed with limiting rubber pads 9 near the side of the limiter connecting arm 1. The two sets of limiting rubber pads 9 move close to the outer wall of the limiter connecting arm 1. Due to their elasticity, they can always keep close to the front and rear outer walls of the limit connecting arm to squeeze and limit it.

[0026] The upper and lower end surfaces of the fixed shell 3 are fixedly connected with mounting blocks 4. The outer side walls of the two sets of mounting blocks 4 are penetrated with screw grooves, and the outer side wall of the hinge block 5 is penetrated with a mounting hole. One end of the screw is passed through the door panel module 2 and rotated into the screw groove to fix the position of the fixed shell 3 in the waterproof car door. Then, the hinge block 5 is close to the mounting position of the car body and fixed to the car body through another set of screws and the mounting holes. The limiter can be installed between the car body and the waterproof car door.

[0027] When in use, the limiter connecting arm 1 is passed through the installation position inside the waterproof car door near one end of the hinge block 5, so that one side of the fixed shell 3 is close to the inner wall of the waterproof car door, and the door panel module 2 simulates the position of the inner wall of the waterproof car door, that is, one side of the fixed shell 3 is close to the outer wall of the door panel module 2, and the two sets of mounting blocks 4 are close to the outer wall position of the door panel module 2. At this time, one end of the screw can be passed through the door panel module 2 and rotated into the screw groove through the outside of the waterproof car door to fix the position of the fixed shell 3 inside the waterproof car door, and then the hinge block 5 is close to the installation position of the vehicle body, and is fixed to the vehicle body through the other set of screws matching the mounting holes, so that the limiter can be installed between the vehicle body and the waterproof car door. When the waterproof car door is opened, the fixed shell 3 follows the waterproof car door, that is, follows the door panel module 2 to move along the limiter connecting arm 1, and one end of the two sets of limit blocks 14 in the limit mechanism 20 installed therein is respectively close to the upper and lower end surfaces of the limiter connecting arm 1 and moves. When moving to the surface of the arc-shaped connecting block 6, the inclined surfaces of the two sets of limit blocks 14 first align with the surface of the arc-shaped connecting block 6. When the two sets of arc connecting blocks 6 are moved to the position between the two sets of arc connecting blocks 6, the elastic force of the telescopic link 13, the supporting spring 1 and the supporting spring 2 can make the limiting block 14 tightly clamped between the two sets of arc connecting blocks 6, limiting the position of the fixed shell 3, thereby stably limiting the position of the opened waterproof car door at this time. In this process, the two sets of fixing plates 8 and the limiting rubber pads 9 installed on the inner wall thereof move with the fixed shell 3, and the two sets of limiting rubber pads 9 move closely against the outer wall of the limiter connecting arm 1. Due to their elasticity, they can always be closely against the front and rear outer walls of the limiting connecting arm to squeeze and limit them. Through the above operation, the upper and lower end surfaces and the front and rear surfaces can be well limited, so that the limiting effect of the opened waterproof car door is better.

[0028] The auxiliary mechanism 21 includes two groups of U-shaped support plates 15, both groups of U-shaped support plates 15 are fixedly installed at the outer wall position of the door panel module 2, and T-shaped connecting blocks 16 are inserted inside the two groups of U-shaped support plates 15. An elastic metal strip 17 is fixedly connected between the inner wall of the U-shaped support plate 15 and the outer wall of the T-shaped connecting block 16, and a circular push plate 18 is fixedly installed between the two groups of T-shaped connecting blocks 16. The elastic metal strip 17 in a stretched state is released from the restriction and contracts inside the U-shaped support plate 15, which can drive the T-shaped connecting block 16 to move along the inside of the U-shaped support plate 15 toward the door panel module 2, and can drive the circular push plate 18 to move toward the door panel module 2, thereby pushing the fixed shell 3 to move a certain distance along the outside of the limiter connecting arm 1, to assist the user in closing the waterproof car door.

[0029] Two sets of baffles 22 are fixedly installed on the side of the fixed shell 3 away from the door panel module 2. Movable grooves are provided on the upper and lower surfaces of the connecting head 7. Blocks 19 are inserted into the two sets of movable grooves. A return spring is connected between the bottom end of the block 19 and the bottom end of the movable groove. The circular push plate 18 eventually moves to a position close to the outer wall of the baffle 22, providing the space required for the subsequent connecting head 7 and the block 19 installed thereon to move back to a position close to one side of the circular push plate 18.

[0030] Specifically, when closing the waterproof door, the fixed shell 3 moves to the initial position along the limiter connecting arm 1, which enables the stopper 19 installed on the connecting head 7 to move to a position close to one side of the return push plate 18 and then continue to move. During this process, the inclined surface of the stopper 19 contacts the outer wall of the return push plate 18 and gradually shrinks into the movable groove. The reset spring is compressed until the connecting head 7 completely passes through the return push plate 18. At this time, the elastic metal strip 17 in the stretched state is released from the restriction and shrinks in the U-shaped support plate 15, which can drive the T-shaped connecting block 16 to move along the inside of the U-shaped support plate 15 toward the door panel module 2. This drives the return push plate 18 to move toward the door panel module 2, thereby pushing the fixed shell 3 to move a certain distance along the outside of the limiter connecting arm 1, thereby assisting the user to close the waterproof car door, making it more labor-saving to close the waterproof car door, and the return push plate 18 finally moves to a position close to the outer wall of the baffle 22, providing the subsequent connecting head 7 and the stop block 19 installed thereon with the space required to move back to a position close to one side of the return push plate 18. After moving to one side again, the waterproof car door continues to be pushed, driving the fixed shell 3 to move forward a certain distance, and then it can be restored to its initial position, assisting in closing the waterproof car door next time.
