Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a vehicle trunk limiting hinge. Background Technology

[0002] A car trunk hinge connects the trunk lid to the vehicle body, allowing the lid to open and close. The trunk can be installed in the vehicle's trunk for storing items. Existing trunk hinges typically only function as pivots; the user manually opens or closes the trunk lid, and when it's opened to a certain angle, they need to hold the lid open with their hand. Another solution is to use friction between two relatively rotating parts to hold the trunk lid at a specific opening angle. However, this method requires high-quality parts; errors in part dimensions or assembly can easily lead to problems such as rotational jamming and difficulty in maintaining the opening. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problem that the processing and assembly of existing limit hinges are quite difficult.

[0004] To achieve the objectives of this utility model, the following technical solution is adopted:

[0005] A vehicle trunk limiting hinge includes a fixed base, a rotating component, an elastic component, a first sliding component, and a second sliding component. The rotating component is pivotally connected to the fixed base via a first shaft located on one side of the central axis of the fixed base. The fixed base has a receiving cavity, in which the elastic component is disposed. The first sliding component is disposed above the elastic component, and the second sliding component is disposed above the first sliding component and contacts it via an inclined surface. The second sliding component is pivotally connected to the rotating component via a second shaft. The first and second shafts are arranged parallel to each other. When the trunk is opened, the first and second sliding components move upward, and the elastic force of the elastic component is greater than the pressure applied. When the trunk is closed, the first and second sliding components move downward.

[0006] In some embodiments, the elastic element is arranged vertically, and several elastic elements are arranged in parallel.

[0007] In some embodiments, the first slider has a first inclined surface, and the second slider has a second inclined surface that contacts the first inclined surface.

[0008] In some embodiments, the fixed base has an extension arm, and a first shaft passes through a first through hole in the rotating member and a first mating hole in the extension arm.

[0009] In some embodiments, the rotating member has an arc-shaped portion, the arc-shaped portion having a second through hole parallel to the first through hole, the arc-shaped portion being correspondingly provided with an arc-shaped groove of the second sliding member, the arc-shaped groove being located between two hinge holes.

[0010] In some embodiments, a first limiting part is provided on one side of the arc-shaped portion, and the first limiting part is correspondingly provided with the arc-shaped groove.

[0011] In some embodiments, the rotating member has a second limiting portion, and a baffle corresponding to the second limiting portion is provided between the extension arms of the fixed base.

[0012] In some embodiments, the first shaft and the second shaft are located above the receiving cavity.

[0013] The vehicle trunk limiting hinge provided by this utility model has the following advantages:

[0014] This utility model employs a first and a second sliding member and an elastic member. The elastic force of the elastic member enables the second sliding member to move obliquely, thereby supporting the open luggage compartment lid to be held at a certain angle. The processing and assembly requirements for the first and second sliding members are relatively low, effectively reducing costs. Attached Figure Description

[0025] like Figures 1 to 4As shown, this embodiment provides a vehicle trunk limiting hinge, including a fixed base 1, a rotating component 2, an elastic component 3, a first sliding component 4, and a second sliding component 5. The rotating component 2 is pivotally connected to the fixed base 1 via a first shaft 6. The fixed base 1 is used to connect to the vehicle body 10 and provides installation space for the elastic component 3 and the sliding component. The fixed base 1 is set in a groove 101 in the vehicle body 10, which can reduce the space occupied by the fixed base 1. The rotating component 2 is connected to the trunk lid 20, and the first shaft 6 enables the rotating component 2 to rotate, realizing the opening or closing of the trunk lid 20. The first shaft 6 is located on one side of the central axis X of the fixed base 1, so that the force of the elastic component 3 can support the trunk lid 20. The fixed base 1 has a receiving cavity 11, and the elastic component 3 is set in the receiving cavity 11. In this embodiment, the elastic component 3 is a spring, which is vertically set and two elastic components are set in parallel, so that the elastic force of the elastic component 3 can support the trunk lid. The first sliding component 4 is set above the elastic component 3, and the elastic force acts on the first sliding component 4. The second sliding member 5 is located above the first sliding member 4 and contacts it via an inclined surface. The second sliding member 5 and the rotating member 2 are pivotally connected via the second shaft 7, so that when the rotating member 2 rotates, it can drive the second sliding member 5 to move. The first shaft 6 and the second shaft 7 are arranged parallel to each other. When the trunk is opened, the first and second sliding members move upward, and the elastic force of the elastic member 3 is greater than the pressure it receives. When the trunk is closed, the first and second sliding members move downward. Specifically, the user manually operates the trunk lid to open or close it. When the trunk lid is closed, the pressure exerted by the trunk lid on the second sliding member 5 and the first sliding member 4 increases, causing them to move downward. The elastic member is compressed and stores force. The trunk lid can be equipped with a latch to lock it to the vehicle body, which is conventional technology in this field and will not be described in detail. When the trunk lid is open, as the trunk lid tilts, the pressure on the first and second sliding members decreases. When it reaches equilibrium with the elastic force, the trunk lid can be held at a certain angle. Through the above technical solution, the trunk lid can be easily opened, and at the same time, the trunk lid can be kept in the open position for easy access to items. During the opening process, the second slider 5 moves upward along the slope to support the suitcase lid.

[0026] Specifically, the first sliding member 4 has a first inclined surface 41, and the second sliding member 5 has a second inclined surface 51 that contacts the first inclined surface 41, so that when the first sliding member 4 moves up and down, the second sliding member 5 can move obliquely relative to the first sliding member 4. The fixed base 1 has an extension arm 12, and the first shaft 6 passes through the first through hole 21 of the rotating member 2 and the first mating hole 121 of the extension arm 12, so that the rotating member 2 can rotate relative to the fixed base 1. The rotating member 2 has an arc-shaped portion 22, and the arc-shaped portion 22 has a second through hole 23 parallel to the first through hole 21. The arc-shaped portion 22 is correspondingly provided with the arc-shaped groove 53 of the second sliding member 5, and the arc-shaped groove 53 is located between the two hinge holes 52. When the rotating member 2 rotates, it smoothly drives the second sliding member 5 to move upward. A first limiting part 24 is provided on one side of the arc-shaped portion 22, and the first limiting part 24 is correspondingly arranged with the arc-shaped groove 53. When the rotating member 2 rotates to the point where the first limiting part 24 abuts against the outer side 531 of the arc-shaped groove 53, the rotating member 2 rotates to the top dead center position. The rotating member 2 has a second limiting part 25, and a baffle 13 corresponding to the second limiting part 25 is provided between the extension arms 12 of the fixed base 1. When the trunk lid is opened to the top dead center, the second limiting part 25 abuts against the baffle 13. Through the first and second limiting parts, the trunk lid is prevented from opening too large an angle, which could damage the hinge. The first shaft 6 and the second shaft 7 are located above the receiving cavity 11, allowing the trunk lid to open at a larger angle.

[0027] This embodiment uses a first and a second sliding member and an elastic member. The elastic force of the elastic member enables the second sliding member to move obliquely, thereby supporting the open trunk lid to be held at a certain angle. The processing and assembly requirements of the first and second sliding members are low, effectively reducing costs.

[0028] The technical principles of this utility model have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
