Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobiles, in particular to an armrest box mounting bracket. Background Art
[0002] The car armrest box is an automotive accessory installed between two seats. Most existing car armrest box brackets are installed in the Z direction with screws on the armrest box to support the armrest box. However, the armrest box bracket has a complex structure, high cost and many consumables, and is not conducive to lightweighting of the entire vehicle. When the vehicle brakes suddenly or encounters a rear-end collision during driving, the middle passenger in the back row leans forward due to inertia, which can easily cause the head to hit the armrest. If the armrest bracket is too strong, it will not have the effect of crushing and absorbing energy, which will increase the risk of head injury to the passenger. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides an armrest box mounting bracket, including a bracket body, which is applied between the armrest box and the sheet metal. The bracket body is installed on the sheet metal by screws, and the side surface of the bracket body is screwed to the lower end of the armrest box to fix the armrest box in the Y direction.
[0004] Preferably, the bracket body comprises a bottom plate and side plates connected to both ends of the bottom plate, and reinforcing ribs are provided at the connection between the bottom plate and the side plates.
[0005] Preferably, the bracket body is overall U-shaped, and the side panels are perpendicular to the bottom panel.
[0006] Preferably, the bottom plate is provided with a first folded edge on a side along the length direction, and the first folded edge is bent upward.
[0007] Preferably: a weight-reducing hole is provided in the middle of the bottom plate to reduce the weight of the bottom plate.
[0008] Preferably, sheet metal mounting holes are provided at both ends of the bottom plate, and screws are installed at the sheet metal mounting holes to fix the bottom plate and the sheet metal.
[0009] Preferably, the side plate is provided with a second folded edge along the side edge in the length direction, and the second folded edge is bent inwardly.
[0010] Preferably, an armrest box mounting hole is provided on the upper end of the side panel, and screws are installed at the armrest box mounting hole to fix the side panel and the armrest box.
[0011] Preferably, a third folded edge is provided at one end of the side plate away from the bottom plate, the third folded edge is bent inwardly, and an upper end surface of the third folded edge is a plane.
[0012] Preferably: a weakened groove is provided between the third folded edge and the armrest box mounting hole, and the weakened groove is bent.
[0013] Technical effects and advantages of the utility model:
[0014] In the utility model, the bracket body has a simple structure. When the bracket body is pressed down by an external force, the weakened groove on the bracket body will cause the third folded edge to deform, playing a role of crushing and absorbing energy, thereby reducing the impact deceleration and protecting the head safety of the middle passenger in the rear row.

DETAILED DESCRIPTION
[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.
[0021] See also Figures 1-2 In this embodiment, an armrest box mounting bracket is provided, including a bracket body 3, which is applied between the armrest box 1 and the sheet metal 2. The bracket body 3 is installed on the sheet metal 2 by screws, and the side surface of the bracket body 3 is screwed to the mounting platform extending from the lower end of the armrest box 1 to fix the armrest box 1 in the Y direction to ensure overall stability.
[0022] In this embodiment, see Figure 3As shown, the bracket body 3 includes a bottom plate 31 and side plates 32 connected to both ends of the bottom plate 31. Reinforcing ribs 33 are provided at the connection between the bottom plate 31 and the side plates 32. The bracket body 3 is U-shaped as a whole, and the side plates 32 are perpendicular to the bottom plate 31, so that the auxiliary instrument panel is more stable and will not shake left and right.
[0023] Furthermore, the bracket body 3 is an integrally formed structure, which has a relatively simple structure and a low manufacturing cost, and is conducive to lightweighting of the entire vehicle.
[0024] Furthermore, a first folded edge 311 is provided on the side of the bottom plate 31 along the length direction, and the first folded edge 311 is bent upward. A weight-reducing hole 312 is provided in the middle of the bottom plate 31 to reduce the weight of the bottom plate 31. Sheet metal mounting holes 313 are provided at both ends of the bottom plate 31, and screws are installed at the sheet metal mounting holes 313 to fix the bottom plate 31 to the sheet metal 2.
[0025] Furthermore, a second folded edge 321 is provided on the side of the side panel 32 along the length direction, and the second folded edge 321 is bent inwardly. An armrest box mounting hole 322 is provided at the upper end of the side panel 32, and screws are installed at the armrest box mounting hole 322 to fix the side panel 32 to the armrest box 1. A third folded edge 323 is provided at one end of the side panel 32 away from the bottom plate 31, and the third folded edge 323 is bent inwardly, and the upper end surface of the third folded edge 323 is a plane, and a weakened groove 324 is provided between the third folded edge 323 and the armrest box mounting hole 322, and the weakened groove 324 is bent.
[0026] For further information, see Figure 4 As shown, a support rib 11 is provided at the bottom of the armrest box 1, and the lower end surface of the support rib 11 is a plane. When the armrest box 1 is installed, the lower end surface of the support rib 11 is attached to the upper end surface of the third folded edge 323, which plays a role of Z-direction limiting.
[0027] Specifically, when the bracket body 3 is pressed downward by an external force, the weakened groove 324 on the bracket body 3 will cause the third folded edge 323 to deform, playing a role of crushing and absorbing energy, thereby reducing the impact deceleration. When the car encounters an accident and brakes suddenly, the head of the middle passenger in the rear row hits the armrest of the auxiliary instrument panel. When the armrest is subjected to force in the Z direction, the weakened groove 324 on the bracket body 3 causes the third folded edge 323 to deform, thereby reducing the deceleration of the head when the armrest is hit by the head, thereby protecting the passenger's head safety to a great extent. This design has the effect of local crushing and absorbing energy while ensuring that it does not affect the strength of the bracket body 3.
[0028] In another embodiment, the bottom plate 31 and the side plates 32 of the bracket body 3 may be welded or screwed together via reinforcing ribs 33 , so that the bracket body 3 is U-shaped as a whole.
[0029] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
