Description

Technical field:

[0001] The utility model belongs to the technical field of hinge connection devices, in particular to a hinge structure of a vehicle box body and a box cover. Background technology:

[0002] Currently, various glove boxes are commonly designed in vehicle interiors to store items. A lid and the glove box body are hingedly connected to each other via a hinge to allow relative rotation between the two. Furthermore, a locking assembly is used to secure the lid and the glove box body together.

[0003] However, the existing box cover can rotate freely but has no hovering function. When opening the cover to take out items, the user needs to hold the cover with his hands all the time. If there is no support to restrict the cover, the cover will fall down naturally, which makes it difficult to operate. Summary of the invention:

[0004] The purpose of the utility model is to provide a hinge structure for a vehicle box body and a box cover, which, by means of the cooperation between the matching part of the hinge wall and the elastic blocking piece, can enable the box cover to be in two states: half-open and hovering, and fully open, which is convenient to use and safe.

[0005] The utility model is achieved in this way:

[0006] A hinge structure of a vehicle box body and a box cover includes a box body and a box cover whose rear side is hinged to the box body through a hinge arm, the hinge arm having a matching portion extending or bending or curving along the direction of the box cover hingedly rotating toward the box body, an elastic baffle is provided on the side wall of the box body, and the outer end of the elastic baffle has an inner limit baffle wall and an outer limit baffle wall, when the box cover is hingedly rotated away from the box body, the matching portion can abut against the inner limit baffle wall and elastically deform the inner limit baffle wall under the push of an external force until it passes over; when the box cover is hingedly rotated toward the box body, the matching portion can abut against the outer limit baffle wall and elastically deform the outer limit baffle wall under the push of an external force until it passes over.

[0008] In the above-mentioned hinge structure of a vehicle box body and a box cover, an assembly groove is provided on the box body, the inner end of the elastic baffle is inserted into the assembly groove, and a limit baffle is provided on the front side wall of the assembly groove. The inner end of the elastic baffle has a pawl portion with a free end facing the notch of the assembly groove and bent backward. The pawl portion abuts against the rear wall surface of the assembly groove and elastically deforms to push the elastic baffle against the limit baffle.

[0009] In the above-mentioned hinge structure of a vehicle box body and a box cover, the limit baffles are arranged at more than two intervals at a transverse interval, the pawl parts are arranged on the left and right sides of the elastic baffle, and the pawl parts on both sides are arranged at more than two intervals along the axial direction of the elastic baffle.

[0010] In the above-mentioned hinge structure of a vehicle box body and a box cover, the mating part is formed by bending the hinge arm, and the bent outer ring wall of the mating part extends outward to form a limiting protrusion, and the upper side wall of the limiting protrusion can abut against the outer limiting retaining wall, and the lower side wall can abut against the inner limiting retaining wall.

[0019] The present invention is further described below with reference to specific embodiments. Figure 1 —4:

[0020] A hinge structure for a vehicle box body and a box cover includes a box body 1 and a box cover 2 whose rear side is hinged to the box body 1 through a hinge arm, the hinge arm having a mating portion 3 extending or bending or curving along the direction of hinged rotation of the box cover 2 toward the box body 1, an elastic baffle 4 is provided on the side wall of the box body 1, and the outer end of the elastic baffle 4 has an inner limit baffle wall 5 and an outer limit baffle wall 6. When the box cover 2 is hinged and rotated away from the box body 1, the mating portion 3 can abut against the inner limit baffle wall 5 and elastically deform the inner limit baffle wall 5 under the push of an external force until it passes over; when the box cover 2 is hinged and rotated toward the box body 1, the mating portion 3 can abut against the outer limit baffle wall 6 and elastically deform the outer limit baffle wall 6 under the push of an external force until it passes over.

[0021] It should be noted that there are two situations in which the positional relationship between the box body 1 and the box cover 2 exists:

[0022] 1. When the fitting portion 3 abuts against the inner limit wall 5, the box cover 2 will be hinged and rotated towards the box body 1 under the action of its own gravity (see the attached figure of the specification) Figure 1 and Figure 2 ): When the box cover 2 is hinged and rotated away from the box body 1 under the action of an external force, the matching portion 3 will abut against the inner limit retaining wall 5, and an external force is required to overcome the elastic force of the inner limit retaining wall 5 to allow the matching portion 3 to pass over the inner limit retaining wall 5. At this time, the box cover 2 can be hinged and rotated toward the box body 1 under the action of its own gravity, and then the matching portion 3 will abut against the outer limit retaining wall 6, and the box cover 2 and the box body 1 will be in a semi-open suspended state; in addition, the box cover 2 can be further pushed away from the box body 1 with the help of an external force to achieve a fully open state between the box cover 2 and the box body 1. Correspondingly, when the box cover 2 is hinged and rotated toward the box body 1 under the action of an external force, the matching portion 3 will abut against the outer limit retaining wall 6, and an external force is required to overcome the elastic force of the outer limit retaining wall 6 to allow the matching portion 3 to pass over the outer limit retaining wall 6, and then the box cover 2 and the box body 1 can be closed.

[0023] 2. When the fitting portion 3 abuts against the inner limit wall 5, the box cover 2 will be hinged and rotated away from the box body 1 due to its own gravity (see the attached figure of the specification). Figure 3 ): When the box body 1 is hinged and rotated away from the box body 1, the matching part 3 abuts against the inner limit stop wall 5. At this time, the box cover 2 and the box body 1 will be in a semi-open suspended state; and the elastic force of the inner limit stop wall 5 can be overcome by an external force, so that the matching part 3 passes over the inner limit stop wall 5, and then the box cover 2 can continue to hinge and rotate away from the box body 1 to reach a fully open state; in addition, when the box cover 2 is hinged and rotated toward the box body 1 under the action of an external force, the matching part 3 will abut against the outer limit stop wall 6, and an external force is required to overcome the elastic force of the outer limit stop wall 6 so that the matching part 3 passes over the outer limit stop wall 6, and then the box cover 2 and the box body 1 will return to a semi-open suspended state.

[0024] That is, the utility model can make the box cover 2 be in two states, half-open and hovering, and fully open, by means of the cooperation between the matching portion 3 of the hinge wall and the elastic blocking piece 4, which is highly practical, easy to use and safe.

[0025] Furthermore, in this embodiment, the specific matching structure of the elastic baffle 4 and the hinge arm on the box body 1 is as follows: a hinge window is provided on the rear side of the box body 1 for the hinge arm to hinge and rotate, a hinge hole is provided at the outer end of the hinge arm, a hinge shaft 7 passes through the hinge hole and its two ends are hinged and rotated on the opposite side walls of the hinge window, and the inner end of the elastic baffle 4 is fixed on the front side wall of the hinge window.

[0026] At the same time, in order to ensure that the inner end of the elastic baffle 4 can be stably connected to the box body 1, the box body 1 is provided with a mounting groove, the inner end of the elastic baffle 4 is inserted into the mounting groove, and a limit baffle 8 is provided on the front side wall of the mounting groove. The inner end of the elastic baffle 4 has a pawl portion 9 with a free end facing the notch of the mounting groove and bent backward. The pawl portion 9 abuts against the rear wall of the mounting groove and elastically deforms to push the elastic baffle 4 against the limit baffle 8. In other words, the inverted hook structure of the pawl portion 9 cooperates with the mounting groove to form a self-locking fixed connection.

[0027] In addition, to further ensure the stable connection of the elastic baffle 4 in the assembly groove, in this embodiment, the limit baffles 8 are arranged at more than two intervals at a horizontal position, and the pawl portions 9 are arranged on the left and right sides of the elastic baffle 4, and the pawl portions 9 on both sides are arranged at more than two intervals along the axial direction of the elastic baffle 4.

[0028] Furthermore, to ensure effective contact between the mating portion 3 and the inner and outer limit retaining walls 5, 6, the mating portion 3 is formed by bending a hinge arm. A limit protrusion 10 extends outward from the curved outer ring wall of the mating portion 3. The upper sidewall of the limit protrusion 10 can abut against the outer limit retaining wall 6, and the lower sidewall can abut against the inner limit retaining wall 5. Furthermore, the inner and outer limit retaining walls 5, 6, are formed by bending an elastic retaining piece 4 back and forth.

[0029] The above embodiment is only one of the preferred embodiments of the present invention and is not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the scope of protection of the present invention.
