The two ends of the connecting rod are respectively connected to the door and the vehicle body, so that when the door is opened or closed, the limit position of the door can be restricted by the limiter.

However, when the door is opened and closed, the two clamping blocks are elastically clamped on the opposite sides of the connecting rod, so that the two clamping blocks slide back and forth in the casing due to the peaks and troughs of the connecting rod. Shifting, especially when the two clamping blocks are clamped at the peak of the connecting rod, since the two clamping blocks are squeezed between the connecting rod and the outer casing, the two clamping blocks are often When it is squeezed to the skew and deformed, the deformed two clamping blocks will not easily slip in the outer casing, and the user must increase the opening and closing force of the door to smoothly open and close the door. In the long run, the life of the limiter will be shortened.

Furthermore, the other two opposite sides of each clamping block are also in contact with the outer casing, and when the clamping block slides, the other two opposite sides will rub against the outer casing, however, the contact area of the other two opposite sides of the clamping block is too large. The frictional force is also too large, which affects the slippery smoothness of the clamping block, and relatively causes the door to be opened and closed.

One of the objects of the present invention is to provide a restraining structure and a door limiting device having the same structure, which can fully absorb the deformation amount of the clamping pad after being pressed and deformed in the casing, thereby ensuring the deformation after being pressed and deformed.

For a fuller understanding of the features, features and aspects of the present invention, reference should be made to the accompanying drawings.

The present invention provides a restraining structure and a door limiting device having the same. As shown in the first figure, the door limiting device includes a limiting structure 100 and a connecting structure 500, and the door limiting device is disposed on a vehicle. Between the door D and the vehicle body B, the opening and closing position of the door D is restricted.

As shown in the second to fourth figures and in conjunction with the fifth to seventh figures, the connecting structure 500 includes a connecting rod 5, and the two ends of the connecting rod 5 are respectively connected to the door D and the vehicle body B, and the connecting rod 5 has a wave shape. The opposite faces of the two opposite faces have a plurality of connected recesses 51 and a plurality of projections 52.

The restricting structure 100 comprises: a casing 1, a pair of clamping pads 2 and a pair of elastic bodies 3. The housing 1 is hollow and disposed on the door D. The housing 1 can be combined with a first housing 11 and a second housing 12, but not limited thereto. The front side of the housing 1 is located at the first side. The casing 11) and the rear side (located in the second casing 12) are respectively provided with an opening 111 and another opening 121 for the connecting rod 5 to be movably inserted.

The two clamping pads 2 are all disposed in the housing 1 to be oppositely clamped to the two phases of the connecting rod 5 opposite. Each of the clamping pads 2 has two contact bodies 21, and in this embodiment, a pad body 22 is further connected between the two contact bodies 21 of the clamping pads 2, and the bottom surface of the pad body 22 (see the fourth figure) corresponds to the foregoing A sliding contact portion 223 is protruded from the opposite surface of the connecting rod 5, and the two clamping pads 2 abut against the opposite faces of the connecting rod 5 with the sliding contact portion 223 (as shown in FIG. 6), for example, It is abutted against the two opposing recesses 51 or the two opposing projections 52. Each of the contact bodies 21 of each of the clamping pads 2 has a contact surface 211. As shown in the seventh figure, the contact faces 211 of the two contact bodies 21 of the respective clamping pads 2 are respectively in contact with the opposite sides 115 of the housing 1. (left and right).

Each of the contact bodies 21 has a buffer space 210 extending longitudinally. As shown in the seventh figure, the buffer space 210 is located between the clamping pad 2 and the opposite side (left side or right side) of the housing 1. In this way, even if the two clamping pads 2 are pressed and deformed by the connecting rod 5, the amount of deformation thereof can be sufficiently absorbed by the buffer space 210, for example, the deformed portion which should originally protrude toward the casing 1 will be because The blocking of the housing 1 automatically reverses toward the inside of the buffer space 210 (with the effect of elastic automatic adjustment), so that the two clamping pads 2 after being pressed and deformed can smoothly slide in the housing 1 When the user opens and closes the door D, the user can still apply the normal force, so as to maintain the smoothness of the door opening and closing operation, thereby increasing the life of the restraining structure 100.

The two elastic bodies 3 are all disposed in the casing 1 , and the elastic bodies 3 are elastically supported between the respective clamping pads 2 and the upper side and the lower side of the casing 1 , as shown in the sixth figure, so as to make the two clamping pads 2 can maintain the state in which the link 5 is elastically held.

In order to allow the elastic body 3 to be elastically contracted and elastically stretched, the pad body 22 supported by the clamping pad 2 can be held between the upper side or the lower side of the housing 1 without being displaced. There are two approaches, which are described below.

Method 1: As shown in the fourth, fifth, and sixth figures, a plurality of grooves 221 are formed in the longitudinal direction of the top surface of the pad body 22, so that the elastic body 3 can be squeezed when it is elastically contracted under pressure. A plurality of convex portions (not shown) are extruded corresponding to the respective grooves 221, and the convex portions of the elastic body 3 are correspondingly inserted into the respective grooves 221, so that a positioning effect can be produced. Another effect derived from the practice: the original clamping pad 2 will slightly deform the top surface of the pad body 22 during plastic injection molding, but because the present invention has a plurality of grooves 221 on the top surface of the pad body 22, the pad is made. The body 22 is thinned, so that the amount of deformation of the depression at the time of injection molding is minimized.

Method 2: As shown in the fourth, fifth, and sixth figures, the upper side of the two contact bodies 21 of each of the clamping pads 2 protrudes from the top surface of the pad body 22, and the pad body 22 protrudes upward and has two positioning positions. The upper edge of the two contact bodies 21 and the two positioning members 222 are enclosed by a positioning space 23, and one end surface of the elastic body 3 is positioned in the positioning space 23 of the clamping pad 2.

Further, in order to reduce the frictional force between the other two opposite sides (front side and rear side) of the ferrule 2 and the casing 1, as shown in the fourth, fifth, and seventh figures, the contact bodies 21 of the nip pad 2 are provided. The two opposite sides (front and rear sides) are respectively provided with a contact rib 212 so that the contact bodies 21 are respectively contacted with the other opposite sides (front side and rear side) of the housing 1 by the two contact ribs 212, respectively. That is, the gaps 112, 122 are separated from each other by the contact ribs 212 between the contact bodies 21 and the housing 1 (see the seventh figure), thereby achieving the purpose of reducing the contact area and reducing the friction force. The pad 2 can slide more smoothly and has a better opening and closing effect than the door D.

In summary, the present invention has the following effects compared to the prior art: by means of clips The holding pad 2 has two contact bodies 21, and each contact body 21 is further provided with a buffer space 210, so that the deformation amount of the clamping pad 2 deformed by being pressed by the connecting rod 5 can be sufficiently absorbed by the buffer space 210, thereby The pinned pad 2 can still smoothly slide in the casing 1, so that the smoothness of the door D opening and closing operation can be maintained, thereby increasing the life of the restraining structure 100. Contact ribs 212 are respectively protruded from opposite sides of the contact body 21 of the clamping pad 2 so that the contact bodies 21 are respectively contacted with the other two opposite sides (front side and rear side) of the housing 1 by the two contact ribs 212. Therefore, the purpose of reducing the contact area and reducing the frictional force is achieved, so that the clamping pad 2 can be smoothly slid in the casing 1 and the door D can be opened and closed relatively better.

In addition, the present invention has other effects: by providing a plurality of grooves 221 on the top surface of the pad body 22, or by the upper sides of the two contact bodies 21 protruding from the pad body 22 and the top surface of the pad body 22 Two positioning members 222 are protruded to form a positioning space 23 so that the elastic body 3 can remain supported between the housing 1 and the pad body 22 of the clamping pad 2 during the elastic contraction and the elastic stretching operation. Shift. By providing a plurality of grooves 221 in the top surface of the pad body 22, the pad body 22 can be correspondingly thinned, thereby minimizing the amount of deformation of the pin when the pad 2 is formed.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the invention, and the equivalent structural changes of the present invention and the contents of the drawings are all included in the present invention. Within the scope of the rights, it is given to Chen Ming.
