Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of door inner panels, and in particular to a side-impact crack-resistant door inner panel structure and device. Background Technology
[0002] Because the door panels are made of plastic and are assembled using standard plastic clips, a large impact during a side collision can cause the inner door panel to detach and warp in the area around the occupant's shoulder, causing injury.
[0003] The existing technology has the problem that the connection structure between the inner door panel and the door guard panel is not strong enough. Most door panels are directly snapped together without screws to secure them. In the event of a collision, the snap-fit structure is easy to fall off, which cannot effectively prevent the inner door panel from breaking on the side. Utility Model Content
[0004] The purpose of this utility model is to provide a side-impact crack-resistant door inner panel structure and device to solve the technical problem that the connection structure between the door inner panel and the door guard panel is not strong enough. Most door panels are directly snapped together without screws to increase the fastening. The snap-fit structure is easy to fall off during a collision, which cannot effectively prevent the door inner panel from breaking on the side. The purpose of this utility model is to improve the connection structure between the door inner panel and the door guard panel and improve driving safety.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A side-impact crack-resistant door inner panel structure includes:
[0007] A door panel assembly, wherein a stress-bearing area is provided on the inner side of the door panel assembly;
[0008] A buffer block is disposed within the force-bearing area to absorb energy and buffer after a collision.
[0009] The buffer block includes a first buffer polyhedron block and a second buffer polyhedron block. The first buffer polyhedron block is disposed on the left side inside the door panel assembly, and the second buffer polyhedron block is disposed on the top of the door panel assembly.
[0010] The buffer point structure disperses and releases the impact force of the collision, thus dispersing the impact force on the shoulder of the door panel assembly.
[0011] As a preferred embodiment of this utility model, the buffer point structure includes a first dispersion component and a second dispersion component;
[0012] The first dispersion component includes a first buffer protrusion and a plurality of first reinforcing ribs, the first reinforcing ribs being spaced apart on the side of the first buffer protrusion;
[0013] The second dispersion member includes a second buffer protrusion and a plurality of second reinforcing ribs, the second reinforcing ribs being spaced apart on the side of the second buffer protrusion.
[0014] As a preferred embodiment of this utility model, the door panel assembly is provided with a plurality of plastic nut seats, which are connected to the door panel assembly by self-tapping screws.
[0015] As a preferred embodiment of this utility model, several of the plastic nut seats are respectively covered with screw plugs, door light decorative covers and switch panels to conceal their appearance.
[0016] Another objective of this utility model is to provide a device with a side-impact crack-resistant inner door panel structure, comprising:
[0017] The door panel assembly described above includes a door and window frame decorative panel assembly.
[0018] A tensile nut seat is provided inside the door panel assembly and is used to connect the door panel assembly and the door and window frame decorative panel assembly via self-tapping screws.
[0019] As a preferred embodiment of this utility model, the tensile nut seat is located on the side of the door and window frame decorative panel assembly.
[0020] The beneficial effects of this utility model are:
[0021] 1. The buffer block provides initial cushioning, and the first and second dispersion components of the buffer point structure provide secondary cushioning. Both enhance the overall strength, prevent the door panel from deforming and falling off during a side impact, and improve driving safety.
[0022] 2. By covering the plastic nut seat with screw plugs, door light decorative covers, and switch panels respectively, the strength of the screw plugs, door light decorative covers, and switch panels is not only improved, but the appearance is also enhanced after covering them.
[0023] 3. The anti-tensile nut seat can prevent the door panel assembly from displacing and warping in the Y direction when subjected to side impact, thereby improving the overall strength of the door panel. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0037] Example 1:
[0038] like Figures 1 to 6 As shown, a side-impact crack-resistant door inner panel structure includes: a door panel assembly 1, with a stress-bearing area 11 provided on the inner side of the door panel assembly 1, wherein a buffer block 12 is provided in the stress-bearing area 11 to absorb energy and buffer after collision, thereby improving the buffering and anti-collision effect of the door panel assembly 1.
[0039] like Figures 1 to 6 As shown, the buffer block 12 includes a first buffer polyhedron block 121 and a second buffer polyhedron block 122. The first buffer polyhedron block 121 is disposed on the left side of the inner side of the door panel assembly 1, and the second buffer polyhedron block 122 is disposed on the top of the door panel assembly 1.
[0040] The buffer point structure 2 disperses and releases the impact force from the collision, thus dispersing the shoulder impact force of the door panel assembly 1. The buffer point structure 2 includes a first dispersion component 21 and a second dispersion component 22.
[0041] The first dispersion component 21 includes a first buffer protrusion 211 and a plurality of first reinforcing ribs 212. The first reinforcing ribs 212 are spaced apart on the sides of the first buffer protrusion 211. The first buffer protrusion 211 acts as a buffer when the vehicle door panel is impacted, reducing impact damage and improving the impact resistance of the door panel assembly 1. At the same time, the first reinforcing ribs 212 strengthen the first buffer protrusion 211, increasing its strength and thus improving the overall strength.
[0042] Similarly, the second buffer member 22 includes a second buffer protrusion 221 and a plurality of second reinforcing ribs 222, which are spaced apart on the sides of the second buffer protrusion 221. When the vehicle door panel is impacted, the second buffer protrusion 221 can buffer the impact, reduce impact damage, and improve the impact resistance of the door panel assembly 1. At the same time, the second reinforcing ribs 222 strengthen the second buffer protrusion 221, increase its strength, and thus improve the overall strength.
[0043] In this embodiment, the door panel assembly 1 is provided with a plurality of plastic nut seats 3, which are connected to the door panel assembly 1 by self-tapping screws, thereby improving the connection stability between the door panel assembly 1 and the external device.
[0044] In this embodiment, several plastic nut seats 3 are respectively covered with screw plugs 31, door light decorative covers 32 and switch panels 33 to cover the appearance and improve the overall aesthetics.
[0045] Example 2: A device with a side-impact crack-resistant inner door panel structure, comprising: a door panel assembly 1 as described above, on which a door and window frame decorative panel assembly 4 is provided; a tensile nut seat 5, disposed inside the door panel assembly 1, which connects the door panel assembly 1 and the door and window frame decorative panel assembly 4 by means of self-tapping screws, thereby improving the connection stability between the door panel assembly 1 and the door and window frame decorative panel assembly 4.
[0046] Among them, the tensile nut seat 5 is located on the side of the door and window frame decorative panel assembly 4, thereby connecting the door and window frame decorative panel assembly 4 and the door panel assembly 1 on the side. This can prevent the door panel assembly 1 from displacing and warping in the Y direction when subjected to side impact force. Meanwhile, several plastic nut seats 3 and self-tapping screws enhance the X-direction strength of the door panel, thereby improving the overall strength of the door panel assembly.
[0047] In summary: the buffer block 12 provides initial cushioning, and the first and second dispersion components 21 and 22 of the buffer point structure 2 provide secondary cushioning, both enhancing overall strength and preventing the door panel from deforming and detaching during a side impact, thus improving driving safety. By covering the plastic nut seat 3 with screw caps 31, door light decorative covers 32, and switch panels 33 respectively, not only is the strength of these components improved, but their appearance is also enhanced. The tensile-resistant nut seat 5 prevents the door panel assembly from shifting and warping in the Y direction during a side impact, thus improving the overall strength of the door panel.
