DETAILED DESCRIPTION

[0046] The first embodiment is:

[0047] See also Figure 1 to Figure 7 ,in Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the present invention. Figure 2 The present invention Figure 1 A magnified view of the local structure at A. Figure 3 is a side view of the first embodiment of the present invention. Figure 4 The present invention Figure 3 Local structure cross-sectional view at BB. Figure 5 The present invention Figure 4 Enlarged view of the local structure at location C. Figure 6 It is a partial structural diagram of the first embodiment of the present invention. Figure 7 The present invention Figure 6The present invention provides a door limiter structure, including a pull rod 101, and a limiter 102 fixedly arranged on one side of the pull rod 101 and a movable component; the movable component includes a moving part 103 with a central opening, a friction part 104, a mounting part 105, a first elastic part 106, a plurality of friction ridges 113 and a dry root reinforcement rib 114; the moving part 103 has an arc-shaped notch 107, a notch 108 is arranged at the plane of the arc-shaped notch 107, an arc-shaped groove connected to the notch 108 and a limiter 109 connected to the arc-shaped notch 107 are arranged on the inner side wall; the mounting part 105 includes a disc 110, a rotating disc 111 and a clamping block 112; the friction part 104 includes a friction block 115 and a holding piece 116; the limiter 102 includes a limiter 117 and a buffer pad 118;

[0048] According to this specific embodiment, the pull rod 101 and the limit body 117 are integrally formed, and a recessed portion is provided on the pull rod 101 to control the opening and closing angle of the door to avoid the door being directly closed after being opened and closed to the maximum angle for the first time or the door being in an open state and being slightly resisted by an external force, thereby affecting safety; by utilizing the first elastic member 106 to resist the friction member 104, the friction member 104 is always kept in contact with the surface wall of the pull rod 101, thereby playing an effective role in controlling the opening and closing angle of the door, and in addition, the friction member 104 can be worn to the maximum extent, its service life can be increased, and the cost of replacing the friction member 104 can be saved; in addition, butter can be applied to the contact point between the friction member 104 and the surface wall of the pull rod 101, so as to increase the lubricity of the friction member 104 and the surface wall of the pull rod 101, so that the friction member 104 can be used for a longer period of time and have a longer service life.

[0049] First, the rotating disk 111 is rotatably connected to the disk 110 and is disposed below the disk 110. The rotating disk 111 is also fixedly connected to the first elastic member 106. The clamping block 112 is fixedly connected to the disk 110 and is located on the outer side wall of the disk 110. The clamping block 112 is embedded in the limiting opening 109. The disk 110 and the arc-shaped notch 107 can rotate, and the rotating disk 111 and the disk 110 can also rotate. When the disk 110 rotates, the first elastic member 106 will not be twisted under the action of the rotating disk 111, and the first elastic member 106 is stationary relative to the disk 110.

[0050] Any of the friction ridges 113 is fixedly connected to the disk 110 and is located above the disk 110. The provision of the friction ridges 113 can increase the friction between the disk 110 and a tool or a finger, and easily realize the rotation of the disk 110.

[0051] Secondly, any of the reinforcing ribs 114 is fixedly connected to the moving member 103 and is located at an end surface of the moving member 103 close to the limiting member 102 ; the provision of the reinforcing ribs 114 can increase the overall structural strength of the moving member 103 .

[0052] Again, the limiter 117 is fixedly connected to the pull rod 101, and the buffer pad 118 is fixedly connected to the limiter 117 and is located at one end of the buffer pad 118 close to the moving member 103. After the moving member 103 slides to a position close to the limiter 117, the moving member 103 contacts the buffer pad 118, so that the buffer pad 118 plays a role in buffering the force.

[0053] Specifically, the friction member 104 is placed in the movable member 103, and then the first elastic member 106 is extended into the movable member 103 through the arc-shaped notch 107 and abuts against the abutting sheet 116. The abutting sheet 116 can prevent the first elastic member 106 from directly contacting the friction block 115 and causing damage to the friction block 115. Then, the disc 110 is placed in the arc-shaped notch 107, and then the block 112 is aligned. Then, the disc 110 is pressed, and the first elastic member 106 is contracted, so that the block 112 is stuck in the notch 108. Then, the disc 110 is twisted with a tool or a finger until the block 112 rotates to The disc 110 is then released below the limiting opening 109, and under the elastic force of the first elastic member 106 itself, the blocking block 112 can be inserted into the limiting opening 109. In addition, the first elastic member 106 is in a state of abutment against the abutting sheet 116. Even if the friction block 115 is greatly worn out after being used for a period of time, the friction block 115 can be kept in contact with the surface wall of the pull rod 101 in real time to avoid a gap between the friction block 115 and the pull rod 101, thereby avoiding a significant reduction in the limiting function or even failure. In addition, under the force condition of the first elastic member 106, the friction block 115 can be fully utilized, its service life can be increased, and costs can be saved.

[0054] The second embodiment is:

[0055] Based on the first embodiment, please refer to Figure 8 to Figure 14 ,in Figure 8It is a schematic diagram of the overall structure of the second embodiment of the present invention. Fig. 9 is a plan view of a second embodiment of the present invention. Fig.10 The present invention Fig. 9 Local structural cross-sectional view at DD. Fig.11 The present invention Fig.10 Local structure cross-sectional view at EE. Fig.12 The present invention Fig.10 Enlarged view of the local structure at F. Fig.13 The present invention Fig.11 Enlarged view of the local structure at G. Fig.14 It is a partial structural diagram of the second embodiment of the present invention. The present invention provides a door stopper structure, which also includes a locking assembly, the locking assembly includes a slider 203, a plate 204, two pins 205, an upper clamping member 206, a lower clamping member 207, two torsion springs 208, an inner recessed ball 209, two extension pieces 211 and two second elastic members 212; the side wall of the moving member 103 also has a feeding groove 201 and an inner sliding groove 202; the inner recessed ball 209 includes a ball 213 and a spiral column 214;

[0056] According to this specific embodiment, when the door limiter is assembled, the ball 213 is inserted into the clamping cavity 210 to preliminarily lock the position of the friction block 115 in the movable member 103; in addition, the setting of the torsion spring 208 can make the size of the clamping cavity 210 formed between the upper clamping member 206 and the lower clamping member 207 adjustable, and after the ball 213 is separated from the clamping cavity 210, the size of the clamping cavity 210 can be restored, that is, the positions of the upper clamping member 206 and the lower clamping member 207 are restored.

[0057] The extension piece 211 is fixedly connected to one side of the upper clamping member 206 and the lower clamping member 207 , and the extension piece 211 is movably connected to one end of the second elastic member 212 , and the other end of the second elastic member 212 is movably connected to the plate body 204 .

The clamping cavity 210 can clamp the ball 213, and the spiral column 214 can separate the ball 213 from the friction block 115. When the friction block 115 is seriously worn, the friction block 115 can be replaced alone without replacing the spiral column 214 and the ball 213, thereby saving the later replacement cost for the car owner.

[0060] In this embodiment, when the friction block 115 is severely worn and the friction block 115 is not in contact with the surface wall of the pull rod 101, the first elastic member 106 resists the resisting plate 116, and the friction block 115 is subjected to force, so that the spiral column 214, the sphere 213, the clamping cavity 210 and the plate body 204 are subjected to force, thereby driving the slider 203 to move in the inner groove 202, and finally making the friction block 115 in real-time contact with the surface wall of the pull rod 101, so as to avoid the formation of a gap between the friction block 115 and the pull rod 101, and avoid a significant reduction in the limiting function or even failure. In addition, when the friction block 115 is severely worn, the friction block 115 can be pulled to allow the ball 213 to disengage from the clamping cavity 210, and then the friction block 115 can be disengaged from the interior of the moving part 103 and slide out from the feeding groove 201 for replacement; compared with the previous method of sealing the friction block 115 and requiring the use of special tools to open a specific cover frame to take out the friction block 115, it is more convenient and quick to replace.
