[0034] It should be noted that the following detailed description is exemplary and is intended to provide further illustration of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0035] Embodiment 1

[0036] In a typical implementation manner of the present invention, referring to Figure 3 as shown, a storage hook assembly includes a hook base 131 and a hook 132.

[0037] The back of the hook base 131 is provided with a plurality of flange mounting holes 1311 for clamping with the rear door trim panel assembly 1, and the hook base 131 is provided with a hook mounting hole.

[0038] The hook base 131 should be made of a material with high strength, high rigidity, fatigue resistance and high wear resistance. In this embodiment, polyoxymethylene (abbreviated as POM) material is selected.

[0039] In this embodiment, asFigure 4 As shown, three flanging mounting holes 1311 are provided, which are respectively located at the bottom and both sides of the hook base 131. The two sides and the bottom of the hook base 131 expand outward and are provided with flanging mounting holes 1311, and the flanging mounting holes on both sides are symmetrically arranged.

[0040] The hook mounting hole is located between the three flanging mounting holes 1311. The hook mounting hole of the hook 132 is a rectangular hole and a pin shaft 1321 is provided at the bottom to achieve hinge connection with the hook 132. As Figure 5 shown, pin shafts 1321 are designed on both sides of the hook, and shaft holes 1312 are designed on both sides of the hook mounting hole of the hook base 131. The pin shafts 1321 are installed in the shaft holes 1312 by interference fit.

[0041] The hook 132 has a limiting part and a hook part, and the two are hinged at the lower part of the hook 132 mounting hole at the intersection position; in the closed state, both the hook part and the limiting part are located on the back side of the hook base 131, and the hook part is on the upper side and the limiting part is on the lower side, and the opening direction of the hook part is downward; in the open state, only the hook part is located on the front side of the hook base 131, and the hook part is on the lower side, the limiting part is on the upper side and is used for limiting, and the opening direction of the hook part is upward.

[0042] The limiting part is a plate-like structure. As a limiting structure, during the process of the hook 132 moving from closed to finally open, the limiting part rises to the top and abuts against the hook base 131, which requires the size of the limiting part to be larger than the size of the hook mounting hole so that it cannot pass through.

[0043] The hook 132 can rotate around the rotating shaft, and there are two stop states of maximum opening (open) and return (closed). The hook can move freely between the two stop states. In this embodiment, the maximum movement angle is 120°. When returning (closing), the front state is as Figure 4 shown, when the maximum opening (open) is reached, the front state is as Figure 6 shown, when returning (closing), the back state is as Figure 7 shown, when the maximum opening (open) is reached, the back state is as Figure 8 shown.

[0044] The hook 132 is the main stress-bearing component, and the selected material needs to have the advantages of high strength, high rigidity, and good wear resistance. Polybutylene terephthalate (PBT for short), also known as polybutylene terephthalate, belongs to the polyester series and is one of the toughest engineering thermoplastics. In this embodiment, the hook 132 is made of PBT material.

[0045] In this embodiment, a flanging mounting hole 1311 is provided on the back of the hook base 131. The flanging mounting hole 1311 can be snap-connected with the clip 112 on the back door trim panel assembly 1. When the two are assembled, the storage hook assembly 13 can be installed from the back of the back door trim panel assembly 1, which belongs to a reverse assembly structure. When the hook 132 is pulled by a heavy object, there is no easy gap between the hook base 131 and the surrounding, improving the reliability.

[0046] In addition, the hook 132 is hinged to the hook base 131 through a pin shaft. The hook 132 can rotate around the pin shaft, and there are two stop states: the maximum opening (open) and the return (closed). The hook can move freely between the two stop states. In the closed state, both the hook part and the limiting part are located on one side of the back of the hook base 131, with the hook part on the upper side and the limiting part on the lower side. The opening direction of the hook part is downward, and at this time, the hook is in a hidden state, neither needing to be removed nor affecting the appearance when not in use; in the open state, only the hook part is located on one side of the front of the hook base 131, with the hook part on the lower side and the limiting part on the upper side for limiting, and the opening direction of the hook part is upward.

[0047] In this embodiment, the rotatable storage hook assembly can play a role at different positions along with the opening of the back door and staying at different positions.

[0048] A hook closing limiting flanging structure 1322 is provided on the limiting part, and a hook closing limiting boss structure 1313 for matching and limiting is provided on the hook base 131; a hook opening limiting flanging structure 1323 is provided on the limiting part, and a hook opening limiting boss structure 1314 for matching and limiting is provided on the hook base 131.

[0049] As Figure 7 and Figure 8 shown, in the hook closed state, the hook closing limiting flanging structure 1322 contacts the hook base closing limiting boss structure 1313 to keep the hook in the closed state; in the hook open state, the hook opening limiting flanging structure 1323 contacts the hook base opening limiting boss structure 1314 to keep the hook in the open state. The hook rotates a total of 120° from the closed limit contact position to the open limit contact position. It can be understood that the hook rotation angle can be adjusted according to actual use requirements.

[0050] Embodiment Two

[0051] This embodiment provides a back door trim panel assembly. As Figure 1 and Figure 3 shown, it includes a back door trim panel body 11 and the storage hook assembly 13 installed from its back as described in Embodiment One.

[0052] The back door trim body 11 is provided with clips 112 on its back for snap connection with the flanging mounting holes 1311. The number and positions of the clips 112 correspond to those of the flanging mounting holes 1311.

[0053] The hook assembly 13 is mounted to the back door trim body 11 from the back side, and the clips 112 of the back door trim body are snap-connected into the flanging mounting holes 1311. The back door trim body 11 is designed with a total of 3 clips 112, and through these 3 clips 112, it is ensured that the hook assembly 13 is firmly snap-connected to the back door trim body 11. Since the back of the hook base 131 is designed with flanging mounting holes 1311 and is mounted to the back door trim body 11 from the back side, when the hook 132 is under force on the front side, there will be no problems such as separation or disengagement between the hook assembly 13 and the back door trim body 11, greatly improving the connection reliability and appearance matching effect.

[0054] As Figure 2 shown, the back of the back door trim body 11 is provided with a number of snap seats 111, and the snap seats 111 are used to install snaps 12 to achieve snap connection with the back door sheet metal 2.

[0055] On the back door trim assembly 1, two hook assemblies 13 are symmetrically arranged according to the vehicle's Y0 plane. The height positions of the hook assemblies 13 need to meet the ergonomic requirements for the convenience of the user's operation. When the back door is opened, the two hooks can be used separately to place items such as plush toys, garbage bags, balloons, and food, or can be used simultaneously to place items such as fishing rods and projection screens, greatly enriching the storage and placement functions of the vehicle, especially the expansion of outdoor functions.

[0056] The back door trim body 11 serves as the assembly carrier for all parts and is also the largest exterior part, and needs to balance the requirements of rigidity, strength, cost, and lightweight. Polypropylene (PP for short) is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and is resistant to a variety of organic solvents and acid-base corrosion. In this embodiment, a toughened and reinforced PP + EPDM-T10 material with a flexural modulus ≥ 1700 MPA is selected.

[0057] Embodiment Three

[0058] This embodiment provides a back door, as Figure 2 shown, which includes a back door sheet metal 2 and a back door trim assembly 1 as in Embodiment Two. Snaps 12 are installed on the snap seats 111, and the back door sheet metal 2 is provided with snap mounting holes 21, and the snaps 12 are snap-connected to the snap mounting holes 12.

[0059] The back door trim body 11 is designed with snap seats 111, and the snap seats 111 are snap-connected to the bottom of the snaps 12; the heads of the snaps 12 are snap-connected to the snap mounting holes 21 of the back door sheet metal.

[0060] During the design, the product of the number of the buckles 12 set and the pulling force of a single buckle 12 should be greater than the sum of the bearing capacities of all the hooks 132. In this embodiment, the pulling force of a single buckle 12 ≥ 150 N. The distance between the buckles 12 is designed according to the principle of 180 - 220 mm. A total of 16 buckles 12 are designed for the entire rear door trim assembly 1, ensuring that the rear door trim assembly 1 will not be disengaged from the rear door sheet metal 2 of the vehicle body when the storage hook assembly 13 is subjected to the rated load (3 KG).

[0061] As a connecting member between the rear door trim body 11 and the rear door sheet metal 2, the buckle 12 is made of polyoxymethylene (abbreviated as POM) material with high strength, high rigidity, fatigue resistance and high wear resistance.
