Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, and particularly relates to an unlocking structure for an automobile seat armrest. Background Art
[0002] The car center armrest is also called the car armrest. It was originally designed to provide elbow support for passengers. Later, it developed into a storage box in the car, including an armrest panel, which can facilitate conversation, office work, reading documents, etc. Most of the existing armrests are retractable, which can provide elbow space for the rear passengers. If the armrest is not needed, it can be folded up without affecting the sense of space in the car.
[0003] As a retractable armrest structure, the movement of the armrest retractable structure mainly relies on the armrest unlocking structure for fixing and unlocking. The existing unlocking structure usually only fixes the armrest in the retracted state, and the unlocking and lowering activities of the armrest are in a free activity state. When the armrest is in the extreme position, the armrest is usually maintained stable by the connecting and fixing structure of the armrest body. It is difficult for the actual unlocking structure to achieve precise stability and control of the retracted state of the armrest. Utility Model Content

[0007] An unlocking rivet pin and an external rivet are respectively provided on both sides of the unlocking arm, and the unlocking rivet pin and the unlocking arm are a jacking-type plug-in structure.
[0008] Furthermore, both sides of the unlocking arm are horizontally bent structures, and the horizontal height of one side of the unlocking rivet pin is higher than the horizontal height of one side of the outer rivet.
[0009] Furthermore, the rotational amplitude of the rotating shaft matches that of the curved groove, and the maximum rotational angle of the rotating shaft is 45°.
[0010] Furthermore, an inner gasket is provided on the connection end surface between the unlocking rivet pin and the unlocking arm, and the riveting height of the unlocking rivet pin is less than 2 mm.
[0011] Furthermore, a positioning screw is inserted into the top of the limiting shaft, and the shaft diameter of the positioning screw is larger than the curved groove.
[0012] Furthermore, the connection end between the positioning screw and the limiting shaft is filled with a shaft gasket.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] This type of automobile seat armrest unlocking structure can lock and unlock the unlocking arm through the relative movement of the unlocking arm and the lifting state of the unlocking rivet pin, and use the limiting shaft and the curved groove to limit and guide the curved movement of the unlocking arm to improve the accuracy and controllability of the entire unlocking arm during movement.

[0019] See also Figure 1-3 , the embodiments of the utility model are further described;
[0020] A car seat armrest unlocking structure, comprising a bracket 1 and an unlocking arm 2, wherein the unlocking arm 2 is arranged on the bracket 1, an end of the unlocking arm 2 is protrudingly provided with an integrally formed crank head 9, and a rotating shaft 11 is rotatably matched between the crank head 9 and the bracket 1, a curved groove 10 is slotted on one end of the unlocking arm 2 relative to the crank head 9, and a limiting shaft 4 is penetrated between one end of the curved groove 10 and the bracket 1;
[0021] An unlocking rivet pin 5 and an outer rivet 3 are respectively provided on both sides of the unlocking arm 2, and the unlocking rivet pin 5 and the unlocking arm 2 are a jacking-type plug-in structure.
[0022] The unlocking structure mainly uses the end of the external rivet 3 as the connection end of the external control unlocking pull belt, which serves as the traction structure of the entire unlocking arm 2, so as to control the unlocking arm 2 to make relative axial rotation along the rotating shaft 11 through external tension, and at the same time, according to the curved groove 10 set to the active position of the unlocking arm 2, to guide the activity of the unlocking arm 2, and further through the limit shaft 4 set in the curved groove 10, to be combined and fixed with the bracket 1 structure, and at the same time, the limit positions at both ends of the curved groove 10 can be limited by the limit shaft 4, so as to control the unlocking activity amplitude of the entire unlocking arm 2, thereby improving the control accuracy of the unlocking arm 2;
[0023] On this basis, the unlocking rivet pin 5 at one end of the outer rivet 3 is plugged and fixed with the end of the unlocking arm 2 by means of a latch-type lifting structure to lock the initial position of the unlocking arm 2 and provide a fixed structure for the normal state of the unlocking arm 2 to ensure the reliability of the entire unlocking structure.
[0024] Preferably, both sides of the unlocking arm 2 are horizontally bent structures, and the horizontal height of one side of the unlocking rivet pin 5 is higher than the horizontal height of one side of the outer rivet 3. The relatively distributed horizontal heights can provide space for the axial insertion and extraction activities of the unlocking rivet pin 5, and avoid the influence of the longitudinal activity of the external force of the outer rivet 3 on the unlocking rivet pin 5 in a high horizontal position, thereby improving the reliability of the locking structure.
[0025] On the basis of the above, an inner gasket 7 is provided on the connecting end surface of the unlocking rivet pin 5 and the unlocking arm 2, and the riveting height of the unlocking rivet pin 5 is less than 2 mm, so as to control the relative riveting height of the unlocking rivet pin 5 to ensure that the unlocking rivet pin can be stably inserted into the unlocking arm 2 during axial movement, thereby ensuring the activity accuracy of the entire locking structure.
[0026] Preferably, the rotation range of the rotating shaft 11 matches that of the curved groove 10 , and the maximum rotation angle of the rotating shaft 11 is 45°, so that the unlocking range of the entire unlocking arm 2 is controlled by the maximum rotation angle of 45°.
[0027] Preferably, a positioning screw 8 is inserted into the top of the limit shaft 4, the shaft diameter of the positioning screw 8 is larger than the curved groove 10, and the connecting end of the positioning screw 8 and the limit shaft 4 is filled with a shaft gasket 6. The axially arranged positioning screw 8 is used to lock the axial docking structure between the limit shaft 4 and the curved groove 10 to prevent the limit shaft 4 from loosening out of the curved groove 10, and at the same time, the shaft gasket 6 is used to protect the bolt interface between the limit shaft 4 and the positioning screw 8.
[0028] The implementation method of the device is that the unlocking structure uses an external rivet 3 and an unlocking rivet pin 5 arranged on both sides of the unlocking arm 2 as two extended ends of external control, wherein the unlocking rivet pin 5 is a plug-in type jacking structure, which is externally controlled to release the plug-in fixation with the end of the unlocking arm 2 to unlock the fixation of the unlocking arm 2 and the bracket 1, and the external rivet 3 corresponds to the unlocking pull belt of the external control, and the pull belt applies a force to control the unlocking arm 2 to make a relative axial rotation along the rotating shaft 11. During the process, the activity of the unlocking arm 2 is guided by the curved groove 10, such as Figure 2 As shown, unlocking is completed until it moves to the other end limit position.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
