In order to fully utilize the space and facilities in the vehicle and improve the riding comfort of passengers during vehicle production, an armrest box is usually arranged on a secondary instrument desk of the vehicle to support the elbows of the passengers, and the armrest box can be used as a storage box to improve the convenience. However, the lid of current handrail case has for the box to rock the problem, reduces driver and passenger and uses experience.

In view of the above, the invention provides a hinge structure and a handrail box, and aims to solve the technical problems that a cover body of the handrail box of the existing vehicle shakes relative to a box body, and the use experience of a driver and a passenger is reduced. Fig. 1 to 11 show an armrest box according to an embodiment of the present invention.

Referring to fig. 1, the hinge structure provided by the present invention is used for a console box 200 of an automobile auxiliary instrument desk, and the hinge structure includes a hinge support 1 and a hinge arm 4, wherein one end of the hinge support 1 is used for connecting an upper end of a box body 210 of the console box 200 to form a connecting portion 11, and the other end is used for suspending the upper end of the box body 210 to form an installation portion 2; one end of the hinge arm 4 is hinged to the mounting part 2, and the other end is used for being connected with the cover body 240 of the armrest box 200; the distance from the connecting part 11 to the mounting part 2 is L, and L is more than or equal to 35mm and less than or equal to 60 mm.

In this embodiment, the hinge bracket 1 is divided into the connecting portion 11 and the mounting portion 2, the connecting portion 11 is connected to the upper end of the box 210, and the mounting portion 2 is suspended at the upper end of the box 210, so that when the cover 240 is rotated to open the console box 200, the hinge bracket 1 is subjected to a bending moment M, specifically, a moment arm of the bending moment is a distance L from the connecting portion 11 to the mounting portion 2, and a force F is generated when the cover 240 is rotated, so that M is FL. The larger the distance L between the connecting portion 11 and the mounting portion 2 is, the larger the moment is, so that the shaking amplitude of the cover 240 relative to the box 210 is increased; and the smaller the distance L between the connection part 11 and the mounting part 2, the more convenient it is to assemble. In the scheme, L is not less than 35mm and not more than 60mm, the moment generated when the cover body 240 rotates is reduced, the shaking amplitude of the cover body 240 is reduced, the hinge structure is convenient to assemble, and the assembling efficiency is improved.

Referring to fig. 2 and 3, further, one of the hinge arm 4 and the mounting portion 2 is provided with a rotating shaft 5, and the other is provided with a rotating shaft 5 hole, and the rotating shaft 5 is provided in the rotating shaft 5 hole. Since the diameter of the rotating shaft 5 is smaller, the deflection thereof is larger, and the cover 240 is more likely to shake. In addition, the material of the rotating shaft 5 also has an influence on the shaking amplitude of the cover 240, and the greater the rigidity of the material of the rotating shaft 5, the smaller the shaking of the cover 240 is. According to a material mechanical deflection formula: y is 64M/E pi D ^4, wherein, y: bar deflection, M: bending moment, E: modulus of elasticity, D; the diameter of the rod. It can be known that the flexibility of the hinge is inversely proportional to the diameter of the hinge rotating shaft 5, and the smaller the diameter of the hinge rotating shaft 5 is, the larger the flexibility is, the more easily the armrest cover shakes. Therefore, in one embodiment, the rotating shaft 5 is made of iron, and has a diameter of D1, D1 is not less than 6 mm; in another embodiment, the rotating shaft 5 is made of plastic, and has a diameter D2, D2 is greater than or equal to 10mm, so that the shaking amplitude of the cover 240 is reduced, and the cost is controlled.

Further, referring to fig. 4 and 5, in order to facilitate the assembly of the hinge arm 4 and the mounting portion 2, the mounting portion 2 is provided with two mounting pieces 21 disposed oppositely, and one end of the hinge arm 4 is rotatably disposed between the two mounting pieces 21; the distance between the side face of each hinge arm 4 close to each mounting piece 21 and the corresponding mounting piece 21 is g, and g is more than or equal to 0.2mm and less than or equal to 0.4 mm. The distance g between the side surface of the hinge arm 4 close to each mounting piece 21 and the corresponding mounting piece 21 is controlled to be 0.2mm-0.4mm, so that the hinge arm 4 can be conveniently mounted between the two mounting parts 2, and the assembly efficiency is further improved. At the same time, the shaking influence caused by the overlarge gap between the hinge arm 4 and the corresponding mounting part 21 is also reduced.

Further, referring to fig. 6, the mounting portion 2 is provided with two mounting pieces 21 arranged oppositely, one end of the hinge arm 4 is rotatably arranged between the two mounting pieces 21, in order to improve the connection strength of the mounting pieces 21, in an embodiment, each of the mounting pieces 21 includes a main body plate 211 and a bending plate 212 bent from one end of the main body plate 211 to a direction away from the hinge support 1, the main body plate 211 is fixed to the hinge support 1, and a reinforcing rib 3 is arranged on one side of the bending plate 212 away from the hinge arm 4. The reinforcing rib 3 is provided on the side of the bending plate 212 remote from the hinge arm 4 to improve the connection strength of the mounting member 21. It is understood that, in an embodiment, a side of the main body plate 211 close to and/or far from the hinge bracket 1 is also provided with a reinforcing rib 3 to further improve the connection strength of the mounting member 21.

Specifically, the reinforcing rib 3 includes two first reinforcing ribs 31 and a plurality of second reinforcing ribs 32, the two first reinforcing ribs 31 are disposed at intervals on one side of the bending plate 212 away from the hinge arm 4, each first reinforcing rib 31 extends along a direction away from the main body plate 211, and each first reinforcing rib 31 is disposed obliquely from one end of the bending plate 212 close to the main body plate 211 to one end of the bending plate 212 away from the main body plate 211 in a direction close to the bending plate 212; the second reinforcing ribs 32 are alternately arranged between the two first reinforcing ribs 31. That is, the second reinforcing ribs 32 are uniformly distributed on the side surfaces of the bending plate 212, and the two first reinforcing ribs 31 are sandwiched between the second reinforcing ribs 32, so that the strength of the side surfaces of the bending plate 212 is relatively uniform.

In addition, in order to achieve the above object, the present invention further provides a console box 200 for a vehicle console, wherein the console box 200 includes the hinge structure according to the above technical solution. It should be noted that, the detailed structure of the hinge structure of the armrest box 200 can refer to the above-mentioned embodiment of the hinge structure, and is not described herein again; since the above hinge structure is used in the armrest box 200 of the present invention, the embodiment of the armrest box 200 of the present invention includes all technical solutions of all embodiments of the above hinge structure, and the achieved technical effects are completely the same, and are not described herein again.

Specifically, the console box 200 includes a box body 210, a cover body 240, and the hinge structure as described above, wherein the box body 210 has a storage compartment 220 with an upper side opened; the cover 240 is rotatably disposed at an opening of the storage compartment 220, wherein the connecting portion 11 is connected to the upper end of the box 210, the mounting portion 2 is suspended at the upper end of the box 210, and one end of the hinge arm 4 is connected to the cover 240, so that the cover 240 rotatably covers the opening of the storage compartment 220 around the mounting portion 2.

In an embodiment, the mounting portion 2 is disposed outside the box 210, that is, only the connecting portion 11 is correspondingly connected to the upper end of the box 210, and the mounting portion 2 is not correspondingly located at the upper end of the box 210, so as to solve the shaking of the cover 240 and increase the area of the opening of the storage compartment 220, thereby facilitating the storage of articles for a user.

Further, referring to fig. 7 and 8, when the distance from the connection point of the cover 240 and the hinge arm 4 to the hinge support 1 is too large, the bending moment applied to the cover 240 is also increased, and the risk of the cover 240 shaking is further increased. Therefore, in this embodiment, the distance from the connection point of the cover 240 and the hinge arm 4 to the side of the hinge support 1 away from the box 210 is d, and d is greater than or equal to 5mm and less than or equal to 35 mm. Therefore, on one hand, the interference between the cover 240 and the box 210 during the rotation is avoided, so that the cover 240 can be opened by the rotation; on the other hand, the length of d is reduced, so that the effects of reducing bending moment and reducing shaking amplitude are achieved.

Generally, the box 210 is fixedly connected to the sub console, and in this embodiment, the box 210 is fixedly connected to the sub console through a fixing portion 230. Specifically, referring to fig. 9, the box 210 is provided with a fixing portion 230, the fixing portion 230 is used for being fixedly connected with the auxiliary instrument desk of the automobile, a distance between the fixing portion 230 and the connecting portion 11 in the vertical direction is e, and e is greater than or equal to 30mm and less than or equal to 150 mm. The effective supporting height e of the hinge is generally referred to as the effective supporting height of the hinge, and the effective supporting height e of the hinge is controlled to be 30mm-150mm, so that the storage space of the storage chamber 220 can be ensured, and meanwhile, the structural strength is prevented from being insufficient due to the excessive depth of the storage chamber 220, and the shaking amplitude caused by the bending deformation of the cover 240 when the cover is subjected to the bending moment is reduced. It is understood that the fixing member may be a screw fixing or other forms, which are not limited herein.

Further, referring to fig. 10, when the front end of the cover 240 receives a Y-direction force, a bending torque is generated at a position of the hinge support 1 where the connecting portion 11 is disposed, so that the cover 240 is distorted and deformed, and the cover 240 is further shaken. In an embodiment, the connecting portion 11 includes two connecting members 111 spaced apart from each other in the front-rear direction, a distance between the two connecting members 111 in the front-rear direction is L1, a length of the cover 240 in the front-rear direction is L0, and L1/L0 is greater than or equal to 0.5. In this way, by making the distance between the two connecting members 111 greater than half the length of the cover body 240, the mounting stability of the hinge bracket 1 is improved, and at the same time, the wobbling range of the cover body 240 is reduced.

Because the relative width of the hinge arm 4 is small, the supporting span of the cover 240 is large, and if the structural rigidity of the area is not sufficient, the cover 240 is prone to generate large bending deformation when receiving Y-direction force, so that the cover 240 is prone to shake. Referring to fig. 11, in the present embodiment, the width of the hinge arm 4 is h, the width of the cover 240 is j, and h/j is greater than or equal to 0.65. In this way, the supporting span of the cover 240 and the width of the hinge arm 4 are maintained in the above ratio to reduce the shaking amplitude of the cover 240 when receiving the Y-direction force.

In addition, the armrest box 200 further includes a reinforcing bracket, one end of the reinforcing bracket is fixed on the inner wall of the storage chamber 220, and the other end of the reinforcing bracket is connected to the hinge support 1, so as to improve the connection strength between the hinge support 1 and the box body 210, and further reduce the shaking amplitude of the cover 240.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
