Description

Technical Field

[0001] This utility model relates to the field of armrest hinge technology, specifically to an armrest hinge assembly. Background Technology

[0002] The car armrest box provides storage space and armrest support within the vehicle. Currently, it mainly consists of a cover and a box body, connected by a rotatable hinge. However, many hinges lack an automatic pop-up function, requiring manual pulling to open the armrest box. Some hinges with automatic pop-up function lack damping and hovering capabilities, resulting in hand slippage and poor user comfort. Furthermore, some armrest boxes experience simultaneous stress on both the pop-up and damping mechanisms upon opening, creating a complex stress structure and increasing the failure rate of the armrest hinge. Therefore, we propose an armrest hinge assembly. Utility Model Content

[0003] The purpose of this utility model is to provide a handrail hinge assembly to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A handrail hinge assembly includes an upper hinge bracket, a lower hinge bracket, and two sets of connecting components located between the upper and lower hinge brackets. The left and right sides of the upper hinge bracket are rotatably connected to the left and right sides of the lower hinge bracket via a set of connecting components. Each connecting component includes a pivot, a nut, a damping baffle, a first damping plate, a second damping plate, a third damping plate, and a driving plate located between the second and third damping plates. The inner part of the pivot is flat and cylindrical, and the outer part is cylindrical. A stop post is fixedly provided at the inner end of the pivot, and the other end of the pivot passes through the upper hinge bracket and the lower hinge bracket in sequence. A third damping plate, a driving plate, and a second damping plate are provided between the upper and lower hinge brackets from the inside out. A first damping plate, a damping baffle, and a nut are provided on the outer side of the upper hinge bracket.

[0006] Preferably, the drive plate has a flat, round shaft hole at the top and a first spring clip interface at the bottom. The rotating shaft passes through the shaft hole, and the drive plate is sleeved on the flat, cylindrical part of the rotating shaft.

The elastic component includes a fixed shaft and a left drive spring and a right drive spring. The fixed shaft is inserted into the lower hinge bracket. The left drive spring and the right drive spring are symmetrically sleeved on the fixed shaft. The two ends of the left drive spring and the right drive spring extend outward a certain distance along the vertical direction of the drive spring, and the two extended ends are respectively engaged in the first spring clip interface and the second spring clip interface.

[0010] Preferably, a limiting plate is provided on the upper side of the end of the side wing plate, and a buffer sleeve is provided on the outside of the limiting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0028] Please see Figures 1-8As shown, this utility model provides a technical solution:

[0029] A handrail hinge assembly includes an upper hinge bracket 1, a lower hinge bracket 2, and two sets of connecting components 3 located between the upper hinge bracket 1 and the lower hinge bracket 2. The left and right sides of the upper hinge bracket 1 are rotatably connected to the left and right sides of the lower hinge bracket 2 respectively via a set of connecting components 3. Each connecting component 3 includes a pivot 31, a nut 32, a damping baffle 33, a first damping plate 34, a second damping plate 35, a third damping plate 36, and a damping element located between the second damping plate 35 and the third damping plate 36. A drive plate 37 is placed between damping plates 36; the inner part of the rotating shaft 31 is flat and cylindrical, and the outer part is cylindrical; a stop post 38 is fixedly installed at the inner end of the rotating shaft 31, and the other end of the rotating shaft 31 passes through the upper hinge bracket 1 and the lower hinge bracket 2 in sequence. Between the upper hinge bracket 1 and the lower hinge bracket 2, a third damping plate 36, a drive plate 37, and a second damping plate 35 are arranged from the inside to the outside. A first damping plate 34, a damping baffle 33, and a nut 32 are arranged on the outer side of the upper hinge bracket 1. The top of the drive plate 37 is provided with a flat and round shaft hole 371 that matches the shape of the rotating shaft 31, and the bottom is provided with a first spring clip interface 372. The rotating shaft 31 passes through the shaft hole 371, and the drive plate 37 is sleeved on the flat and cylindrical part of the rotating shaft 31 to prevent relative rotation between the drive plate 37 and the rotating shaft 31. When the drive plate 37 rotates, it can drive the rotating shaft 31 to rotate together.

[0030] In this embodiment, the hinge upper bracket 1 includes: a top plate 11 and a tail plate 12 extending along both sides of the top plate 11 in a "J" shape. The top plate 11 is provided with a plurality of first fixing holes 13, which are used with bolts to connect the hinge upper bracket 1 and the armrest box cover together.

[0031] In this embodiment, the lower hinge support 2 includes: a fixed plate 21 and side wing plates 22 extending vertically along both sides of the fixed plate 21. The fixed plate 21 has a plurality of second fixing holes 23 evenly distributed on it, and a second spring clip interface 24 symmetrically formed on its top. A limiting plate 25 is provided on the upper side of the end of the side wing plate 22 to limit the maximum opening angle of the armrest. A buffer sleeve 251 is fitted over the limiting plate 25, preferably made of latex. An elastic component 4 is provided on the lower side of the side wing plate 22. The elastic component 4 includes a fixed shaft 41, a left drive spring 42, and a right drive spring 43. The fixed shaft 41 is inserted into the lower hinge support 2. The left drive spring 42 and the right drive spring 43 are symmetrically fitted onto the fixed shaft 41. The two ends of the left drive spring 42 and the right drive spring 43 extend outward a certain distance along the vertical direction of the drive spring, and the extended ends are respectively clipped into the first spring clip interface 372 and the second spring clip interface 24. The elastic component 4 uses a drive spring to apply elastic force at the first spring clip interface 372 and the second spring clip interface 24 to drive the bracket on the armrest hinge, thereby realizing the function of the armrest hinge automatically springing up.

[0032] The operation of the armrest hinge assembly in this embodiment is as follows: When the armrest is closed, the drive spring is compressed and undergoes elastic deformation, and the spring clip interface is subjected to the elastic force applied by the drive spring. When the armrest box is opened, under the action of the elastic force, the drive plate 37 drives the rotating shaft 31 to rotate. When the rotating shaft 31 rotates, the friction force generated between it and the upper hinge bracket 1 and the damping plate drives the upper hinge bracket 1 to move upward around the rotating shaft 31. After the drive plate 37 rotates a certain angle, the drive spring returns to its original shape, the elastic force disappears, and the connecting component 3 is no longer subjected to the elastic force. The upper hinge bracket 1 is controlled to stay suspended at any time only by the friction force generated between the upper hinge bracket 1, the lower hinge bracket 2 and the connecting component 3.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
