[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] Please refer to the following Figures 1 to 3 The following describes a lock hook assembly and a vehicle according to an embodiment of the present invention.

[0030] like Figures 1 to 3 As shown, the locking hook assembly of the present embodiment includes: a base plate 1, a reinforcement plate 2, and a locking hook 3. The reinforcement plate 2 is mounted on the base plate 1. The reinforcement plate 2 is provided with a mounting groove 21. The mounting groove 21 and the base plate 1 together form a mounting cavity 211. The locking hook 3 includes a connected locking hook body and a connecting portion 31. The connecting portion 31 extends into the mounting cavity 211 and is connected to the inner wall of the mounting groove 21.

[0031] According to the locking hook assembly of the embodiment of the present invention, the mounting groove 21 on the reinforcing plate 2 and the base plate 1 together form a mounting cavity 211. The connecting portion 31 of the locking hook 3 extends into the mounting cavity 211 and connects to the inner wall of the mounting groove 21. On the one hand, the reinforcing plate 2 can shield the connecting portion 31, thereby improving the appearance quality of the assembled locking hook assembly and eliminating the need for decorative parts, which helps reduce production costs. On the other hand, the cavity structure formed by the reinforcing plate 2 and the base plate 1 can be used to improve the installation strength and rigidity of the locking hook assembly, making it less likely to shake after installation and reducing the problem of abnormal noise during vehicle driving.

[0032] It is understood that when assembling the lock hook assembly, the lock hook 3 can be first installed on the reinforcement plate 2 (i.e., the connecting portion 31 is connected to the inner wall of the installation groove 21), and then the reinforcement plate 2 is assembled on the base plate 1, thereby completing the installation of the lock hook assembly. After the reinforcement plate 2 is installed on the base plate 1, the connecting portion 31 can be hidden in the installation cavity 211 between the base plate 1 and the reinforcement plate 2. Therefore, the user cannot observe the installation structure of the reinforcement plate 2 and the connecting portion 31, thereby improving the appearance quality of the lock hook assembly.

[0033] For example, the connection portion 31 of the hook assembly in this embodiment is welded to the reinforcing plate 2. In the alternative of directly welding the connection portion 31 to the base plate 1, the welded connection portion 31 to the base plate 1 exhibits poor visual quality, and weld slag splashes near the weld seam 4 further deteriorate the appearance. However, in this embodiment, the connection portion 31 of the hook assembly is welded to the reinforcing plate 2, preventing the user from directly observing the weld seam 4, thereby improving the user experience.

[0034] Alternatively, as Figure 1 and Figure 3 As shown, there are at least two connecting parts 31 along the first direction (such as Figure 1 The mounting cavities 211 are arranged in a spaced-apart arrangement (in the left and right directions) and, within a projection plane orthogonal to the first direction, have a triangular cross-sectional profile. Due to the triangular cross-sectional profile of the mounting cavities 211, i.e., the mounting cavities 211 generally exhibit a triangular prism-shaped cavity structure, the strength and rigidity of the connection between the base plate 1 and the reinforcing plate 2, as well as the strength and rigidity of the base portion (connecting portion 31) of the locking hook 3, are enhanced. This not only meets the mandatory luggage compartment impact conditions but also improves the rigidity of the engagement point of the locking hook assembly, thereby avoiding subjective quality issues such as abnormal noise during rear seat travel and shaking caused by insufficient static rear seat mounting rigidity.

[0035] In the example of the present application, the lock hook 3 is U-shaped or semicircular. Figure 2 As shown, two ends of the locking hook 3 along its extension direction form two connecting portions 31 , and the two connecting portions 31 are arranged in the mounting groove 21 at intervals along the first direction.

[0036] Alternatively, as Figure 1 and Figure 3 As shown, the inner wall of the mounting groove 21 is provided with a groove 22, which extends along the length of the connecting portion 31, and at least a portion of the connecting portion 31 fits within the groove 22. Since a portion of the connecting portion 31 fits within the groove 22, the contact area between the connecting portion 31 and the reinforcing plate 2 can be increased. When the connecting portion 31 and the reinforcing plate 2 are welded, the locking hook 3 and the reinforcing plate 2 can be welded more firmly.

[0037] For example, the groove 22 is generally a semi-cylindrical structure, and the outer shape of the connecting portion 31 is a cylindrical structure, thereby improving the matching degree between the connecting portion 31 and the groove 22 and ensuring the firmness of the locking hook 3 after welding.

[0038] Specifically, if Figure 3 As shown, the connection portion 31 is welded to the reinforcing plate 2 and has weld seams 4. The weld seams 4 are arranged on opposite sides of the connection portion 31 and extend along the length of the connection portion 31. It can be understood that each connection portion 31 has two weld seams 4, which are arranged on opposite sides of the connection column in the radial direction and extend along the length of the connection portion 31, thereby further improving the reliability of the welding between the connection portion 31 and the reinforcing plate 2.

[0039] Optionally, the reinforcing plate 2 is riveted to the substrate 1, which can facilitate the reliability of the connection between the reinforcing plate 2 and the substrate 1, and the assembly method and assembly process are simple. On the other hand, compared with the solution of welding the reinforcing plate 2 and the substrate 1, the appearance quality of the reinforcing plate 2 after installation can be improved, thereby enhancing the user experience.

[0040] In some embodiments, as Figure 2 and Figure 3 As shown, the reinforcing plate 2 includes a first bent plate 23 and a second bent plate 24 connected to each other, with an angle formed between the first bent plate 23 and the second bent plate 24. The mounting groove 21 is formed at the connection position of the first bent plate 23 and the second bent plate 24, and the first bent plate 23 and the second bent plate 24 are both connected to the base plate 1. It can be understood that when the first bent plate 23 and the second bent plate 24 are connected to the base plate 1, since the mounting groove 21 is formed at the connection position of the first bent plate 23 and the second bent plate 24, the cross-section of the mounting cavity 211 enclosed by the reinforcing plate 2 and the base plate 1 can be roughly triangular, and the first bent plate 23 and the second bent plate 24 are both connected to the base plate 1, so that the reinforcing plate 2 and the base plate 1 can form a stable support structure, thereby greatly improving the structural strength and rigidity of the lock hook assembly.

[0041] For example, the included angle between the first bent plate 23 and the second bent plate 24 may fluctuate within a certain range above or below 90°.

[0042] Specifically, if Figure 2 As shown, the base plate 1 has a first mating surface and a second mating surface. The first mating surface is in contact with the first bent plate 23, and the second mating surface is in contact with the second bent plate 24. The locking hook assembly includes multiple rivets 5, some of which are inserted through the first bent plate 23 and the first mating surface, while others are inserted through the second bent plate 24 and the second mating surface. It can be understood that the first mating surface is riveted to the first bent plate 23, and the second mating surface is riveted to the second bent plate 24, thereby improving the firmness of the riveted connection between the reinforcing plate 2 and the base plate 1.

[0043] In one example, the riveting form of the reinforcing plate 2 and the base plate 1 is an SPR connection, thereby eliminating the need for pre-drilling holes on the reinforcing plate 2 and the base plate 1 , and the connection method is simple and highly reliable.

[0044] Alternatively, as Figure 2 and Figure 3 As shown, reinforcing plate 2 is provided with a through hole 25, which communicates with mounting cavity 211. This through hole 25 aids in positioning reinforcing plate 2 during installation, serving as a positioning hole. Furthermore, after the hook assembly is installed, the decorative panel covers reinforcing plate 2 to shield it from view. This allows through hole 25 to be used to insert fasteners for securing the decorative panel.

[0045] like Figure 1 and Figure 2 As shown, a vehicle according to an embodiment of the present invention includes a lock hook assembly and a parcel shelf 6 . The lock hook assembly is the lock hook assembly of the present invention, and the base plate 1 is arranged on the lower side of the front crossbeam 61 of the parcel shelf 6 .

[0046] In the vehicle according to the embodiment of the present invention, the mounting groove 21 on the reinforcement plate 2 and the base plate 1 together form a mounting cavity 211, and the connecting portion 31 of the lock hook 3 extends into the mounting cavity 211 and connects to the inner wall of the mounting groove 21. On the one hand, the reinforcement plate 2 can shield the connecting portion 31, thereby improving the appearance quality of the assembled lock hook assembly and eliminating the need for decorative parts, which helps reduce production costs. On the other hand, the cavity structure enclosed by the reinforcement plate 2 and the base plate 1 can be used to improve the installation strength and rigidity of the lock hook assembly, making it less likely to shake after installation and reducing the problem of abnormal noise during vehicle driving.

[0047] Specifically, the front cross member 61 comprises a front wall panel, with a base plate 1 and a reinforcement plate 2 both disposed on the rear side of the front wall panel. The base plate 1 is disposed on the underside of the front wall panel, while the reinforcement plate 2 is disposed on the underside of the base plate 1. The latch hook body extends forward and out of the front wall panel. It is understood that the base plate 1 is configured as the lower plate of the front cross member 61, while the reinforcement plate 2 is disposed at the corner between the Z-direction surface (upper wall surface) and the X-direction surface (front wall surface) of the parcel shelf 6 front cross member 61. This substantially eliminates the need for additional luggage compartment space, thereby facilitating improved space utilization in the vehicle.

[0048] For example, the parcel shelf 6 and base plate 1 are made of stamped aluminum, and the reinforcement plate 2 and lock hook 3 are made of steel. This can not only meet the strength and rigidity requirements of the lock hook assembly, but also reduce the weight of the entire vehicle, which is conducive to the lightweight design of the vehicle.
