Abstract
Description
Technical Field
[0001] The utility model relates to the field of suspension hinges, in particular to a fatigue-resistant armrest suspension hinge assembly. Background Art
[0002] Car armrests, as the name suggests, are components installed inside a car to provide support and comfort to passengers. They are primarily designed to enhance the stability and comfort of passengers during driving, especially in situations such as sharp turns, acceleration or braking. Car armrests are generally divided into several types.
[0003] In the process of opening and closing the automobile armrest, a hinge is required to be used, and the armrest is opened and closed by the set hinge. When the existing hinge is in use, in order to facilitate the armrest to stay in any rotating position, a friction plate is generally provided on the hinge. The friction of the friction plate can achieve a hovering effect of the armrest, thereby improving the convenience during use. However, the hinge in the prior art also has certain shortcomings when in use. Since the hinge achieves hovering through the friction of the friction plate, when the armrest is in the process of rotating, if the armrest is about to be fully opened, and the user at this time still rotates it with a large force, it is easy for the armrest to collide with other parts. Over time, the armrest is likely to be damaged.
[0004] Therefore, it is necessary to provide a new fatigue-resistant armrest suspension hinge assembly to solve the above-mentioned technical problems. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a fatigue-resistant armrest suspension hinge assembly.
[0006] The fatigue-resistant armrest suspension hinge assembly provided by the utility model comprises an upper connecting plate, a lower connecting plate and two connecting devices, end plates are fixedly installed on both sides of one end of the upper connecting plate, the end of the end plate away from the upper connecting plate is bent 90 degrees and fixedly installed with an abutment block, and an elastic member with an arc-shaped end is movably provided on the abutment block, and bending plates are fixedly installed on both sides of one end of the lower connecting plate, and the two end plates are respectively arranged corresponding to the two bending plates, and the two connecting devices are respectively used to connect the two paired ends and the bending plates, and positioning plates are fixedly installed on the side walls away from each other of the two bending plates, and positioning holes are opened on the positioning plates for the ends of the elastic members to move in, and the end of the positioning plate away from the bending plate is an inclined surface for squeezing the ends of the elastic members.
[0007] Preferably, the elastic member includes a spring and a positioning column, the positioning column is movably arranged in a groove opened in the side wall of the abutment block, one end of the positioning column is an arc-shaped structure, the end of the arc surface structure can be moved into the inner side of the positioning hole, and the two ends of the spring are respectively fixedly connected to the bottom wall of the abutment block groove and the end of the positioning column.
[0008] Preferably, the connecting device includes a pin, a connecting plate, a first friction plate, a second friction plate, a first nut and an extrusion piece, the pin is sequentially inserted through the through hole opened in the bending plate, the through hole opened in the connecting plate, the through hole opened in the first friction plate, the through hole opened in the end plate, the through hole opened in the second friction plate and the extrusion piece, and the first nut is threadedly connected to the tail of the pin.
[0009] Preferably, the extrusion piece includes two gaskets, and both of the two gaskets are provided with through holes for inserting nails.
[0010] Preferably, a reinforcement device for reinforcing the two bolts is provided between the two end plates.
[0011] Preferably, the reinforcement device includes a support rod, a sleeve, a threaded tube and a second nut. One end of the support rod is fixedly connected to the sleeve, and the other end of the support rod is sleeved with a threaded tube. The threaded tube is threadedly connected to the support rod. The inner cavity size of the sleeve and the inner cavity size of the threaded tube are both adapted to the tail size of the pin, and the second nut is fixedly sleeved on the threaded tube.
[0012] Compared with the related art, the fatigue-resistant armrest suspension hinge assembly provided by the utility model has the following beneficial effects:
[0013] 1. When the armrest is about to be fully opened, the positioning column is squeezed by the inclined surface, and the positioning column continuously moves in the groove of the abutment block. The compression degree of the spring gradually increases, thereby gradually increasing the friction between the positioning column and the inclined surface. During the rotation process, the user's hand senses the gradually changing force, thereby reminding the user that the armrest is about to rotate to the end.
[0014] 2. When the positioning column moves to the positioning hole, under the action of the spring, the end of the arc-shaped structure of the positioning column moves into the positioning hole. At this time, the armrest is in a fully open state. The positioning column and the positioning hole play a certain positioning role, so that when the user turns the armrest, it is not easy to cause the edge of the armrest to collide with other parts due to excessive rotation of the armrest.
[0015] 3. When the armrest is in a fully rotated state, the spring and the positioning column also play a certain supporting role on the armrest connected to the upper connecting plate, so that the armrest does not only rely on the first friction plate and the second friction plate for suspension, thereby improving the fatigue resistance of the device.

Positioning plates 6 are fixedly installed on the side walls away from the two bending plates 5. Positioning holes 7 are opened on the positioning plates 6 for the ends of the elastic members to move in, and the end of the positioning plate 6 away from the bending plate 5 is an inclined surface 8 for squeezing the ends of the elastic members. The elastic member includes a spring 9. And the positioning column 10, the positioning column 10 is movably arranged in the groove opened on the side wall of the abutment block 3, one end of the positioning column 10 is an arc-shaped structure, the end of the arc surface structure can be moved into the inner side of the positioning hole 7, the two ends of the spring 9 are respectively fixedly connected to the bottom wall of the groove of the abutment block 3 and the end of the positioning column 10, when the armrest is about to be fully opened, the positioning column 10 at this time is squeezed by the inclined surface 8, the positioning column 10 continuously moves in the groove of the abutment block 3, the compression degree of the spring 9 gradually increases, so that the friction between the positioning column 10 and the inclined surface 8 gradually increases, and the user's hand senses the gradually changing force during the rotation process, thereby reminding the user that the armrest is about to rotate to the tail, and a certain positioning effect is played by the positioning column 10 and the positioning hole 7;

[0035] Embodiment 2
[0036] like Figure 10-11As shown, a reinforcement device for reinforcing the two bolts is provided between the two end plates 2, and the reinforcement device includes a support rod 17, a sleeve 18, a threaded barrel 19 and a second nut 20.

When the positioning column 10 moves to the position of the positioning hole 7, under the action of the spring 9, the end of the arc-shaped structure of the positioning column 10 moves into the positioning hole 7.
