Description

Technical Field

[0001] This utility model belongs to the field of automotive parts, and in particular relates to a hinge for an automotive armrest box. Background Technology

[0002] A car armrest hinge is a component used to connect the top cover of a car armrest. The structure of a traditional car armrest hinge is as shown in Chinese utility model patents, such as "CN 208306425 U" entitled "Lightweight Hinge System and Hinge Assembly" and "CN 218343333 U" entitled "A Hinge System for a Car Center Armrest". It includes a lower bracket and an upper bracket rotatably mounted on the lower bracket via a connecting mechanism. The disadvantage is that it lacks an automatic spring-opening function, making it inconvenient for users. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automatic pop-out car armrest hinge.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: a lower bracket and an upper bracket rotatably mounted on the lower bracket via a connecting mechanism. The rear end of the lower bracket is provided with a spring-opening mechanism for automatically opening the upper bracket. The spring-opening mechanism includes a pin and a tension spring. The rear ends of the lower bracket are provided with sliding grooves on both sides. The pin is slidably mounted on the sliding grooves and has lower positioning parts extending out of the sliding grooves at both ends. The tension spring is connected between the pin and the lower bracket. When the upper bracket approaches the closed position, its lower end contacts the lower positioning parts first.

[0005] The lower positioning part is provided with a bushing, which slides in conjunction with the slide groove.

[0006] The upper bracket is provided with a groove that positions and engages with the lower positioning part.

[0007] The lower support is provided with an upper positioning part at its upper end for positioning the upper support after it has been opened into place.

[0008] The upper positioning part is provided with a rubber sleeve.

[0009] When the angle of closure of the upper bracket is less than 10°, its lower end contacts the lower positioning part.

[0010] When the angle of the upper bracket opening is greater than 75°, its upper end contacts the upper positioning part.

[0011] The advantages of the automatic pop-opening car armrest box hinge of this utility model are as follows: when the car armrest box cover is unlocked, it can automatically pop open at a certain angle (generally 10°) to facilitate the user's opening.

[0012] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of the automatic pop-out car armrest box hinge of this utility model;

[0014] Figure 2 This is a partial enlarged view of the automatic pop-out car armrest hinge of this utility model. Detailed Implementation

[0015] Reference Figure 1-2 As shown, the automatic pop-out car armrest hinge of this utility model includes a lower bracket 1 and an upper bracket 3 rotatably mounted on the lower bracket 1 via a connecting mechanism 2. The lower bracket 1 has a pop-out mechanism 4 at its rear end for automatically popping open the upper bracket 3. The pop-out mechanism 4 includes a pin 5 and a tension spring 6. The lower bracket 1 has sliding grooves 7 on both sides of its rear end. The pin 5 is slidably mounted on the sliding grooves 7, and has lower positioning portions 8 extending out of the sliding grooves 7 at both ends. The tension spring 6 connects the pin 5 and the lower bracket 1. When the upper bracket 3 approaches the closed position (i.e., the horizontal contact position), its lower end first contacts the lower positioning portions 8. Therefore, when the upper bracket 3 is in the closed position, the pop-out mechanism 4 exerts a counterforce on the upper bracket 3, thereby automatically popping the upper cover open by a certain angle after the car armrest cover is unlocked.

[0016] Preferably, the lower positioning part 8 is provided with a bushing 9, which slides in conjunction with the groove 7 to improve the wear resistance of the pin 5.

[0017] Preferably, the upper bracket 3 is provided with a groove 10 that engages with the lower positioning part 8 for positioning. This allows the upper bracket 3 to be positioned more stably on the lower positioning part 8.

[0018] Preferably, the lower support 1 is provided with an upper positioning part 11 for positioning the upper support 3 after it has been opened to the correct position, so as to prevent the upper support 3 from being over-opened and causing damage to the hinge. The upper positioning part 11 is provided with a rubber sleeve 12 to provide a cushioning effect.

[0019] Preferably, when the closing angle of the upper bracket 3 is less than 10°, its lower end contacts the lower positioning part 8. This allows the upper cover to automatically spring upward by 10°.

[0020] Preferably, when the angle of opening of the upper bracket 3 is greater than 75°, its upper end contacts the upper positioning part 11.

[0021] The above description is not intended to limit the present invention in any way. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
