Description

Technical Field

[0001] This utility model belongs to the technical field of motor accessories, specifically relating to an anti-detachment hub cover for electric vehicles. Background Technology

[0002] The hub cap is an important component of the electric vehicle wheel hub. It is usually installed in the center of the wheel hub and is used to protect important components such as the hub bolts and bearings in the center of the wheel hub from external dust, mud and water.

[0003] The patent specification with announcement number CN115519933A discloses a car wheel hub cover with a reinforced structure, including a tire hub body, an outer mounting ring, and a protective cover. A hub disc is fixedly connected to the inside of the tire hub body through a connecting frame. The outer mounting ring is installed on one side of the tire hub body. A docking ring is fixedly connected to the front end of the hub disc. A threaded hole is opened on the tire hub body. The protective cover is movably installed inside the outer mounting ring through a telescopic plate.

[0004] This type of hubcap achieves a fixed connection between the hubcap and the wheel hub by connecting the outer ring to the wheel hub body. The hubcap edge is equipped with a first and a second rotating shaft to install the hubcap's spoke structure. The shortcomings of this technical solution are as follows: First, the edge of the hubcap is not directly connected to the wheel hub, resulting in the connection strength between the hubcap and the wheel hub being reinforced only at its center. However, the edge of the hubcap has the highest linear velocity and the greatest centrifugal force when rotating at high speed, making it the most prone to detachment. Second, the connection between the hubcap and the wheel hub consists only of two second connecting rods, supplemented by four first limiting rods for locking, resulting in poor locking force at the center of the hubcap after connection. In other words, the locking force at the center and edge of the hubcap is insufficient, leading to poor anti-detachment ability.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] The purpose of this utility model is to provide an anti-detachment hub cover for electric vehicles. The technical problem to be solved is as follows: When existing hub covers are installed with wheel hubs, there are problems such as the edges not being effectively locked and the center locking force being insufficient.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] An anti-detachment hub cover for electric vehicles includes a rim, a cover body is installed on one side of the top of the rim, and multiple spokes are provided along the edge of the cover body. The side of the spokes closest to the rim is locked to the hub, and the spokes are used to lock the edge position of the hub cover. Multiple pre-locking holes are provided in the middle of the cover body, and a locking hole is provided between two adjacent pre-locking holes. The pre-locking holes and the locking holes are used to lock the center position of the hub cover.

[0009] As a further embodiment of this utility model: a tire bead seat is provided at the top of the wheel rim, the height of the top of the tire bead seat is greater than the height of the top of the cover, a groove is provided at the center of the cover, and the pre-locking hole and the locking hole are both located inside the groove.

[0010] As a further embodiment of this utility model: five pre-locking holes are evenly arranged in the circumferential direction inside the groove, the diameter of the pre-locking holes is smaller than the diameter of the locking holes, and the top of both the pre-locking holes and the locking holes are provided with an inner interface.

[0011] As a further embodiment of this utility model: the cover body is evenly provided with eight spokes along the circumference, and two spokes are provided on the side of the spokes near the rim. An outer locking seat is provided on one side of each of the two spokes, and an outer locking bolt is installed inside the outer locking seat.

[0012] As a further embodiment of this utility model: the two adjacent outer locking bolts and the two spokes form a triangular shape, and one end of the outer locking bolt passes through the rim and connects to the hub.

[0013] As a further embodiment of this utility model: both the rim and the cover are made of aluminum alloy, and a decorative panel is provided at the center of the cover.

[0014] The beneficial effects of this utility model are:

[0015] By connecting the hubcap to the wheel hub and installing smaller locking bolts in each pre-locking hole to pre-install the hubcap, and then fixing it with larger locking bolts through the locking holes, the alternating and evenly installed locking bolts of different sizes can effectively and strongly connect the center position of the hubcap to the wheel hub after installation, thereby improving the connection strength of the center position of the hubcap and improving the hubcap's anti-detachment ability.

[0016] Furthermore, each of the multiple spokes evenly arranged along the circumference has two spokes at its end. The two spokes and the two outer locking bolts form a triangular support mechanism for the outer ring of the hubcap. The outer locking bolts are locked to the hub, which strongly locks the edge of the hubcap. Its technical advantage is that by strengthening the structure of the edge part of the hubcap, combined with the strong locking of the hubcap to the center position, an integrated anti-detachment solution with dual locking of the center and edge positions is formed when the hubcap is connected to the hub.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] like Figures 1 to 4 As shown, an anti-detachment hub cover for electric vehicles includes a rim 1, a cover 2 installed on one side of the top of the rim 1, a plurality of spokes 3 arranged along the edge of the cover 2, the side of the spokes 3 near the rim 1 being locked to the hub, a plurality of pre-locking holes 4 arranged in the middle of the cover 2, and a locking hole 5 arranged between two adjacent pre-locking holes 4, the pre-locking holes 4 and the locking holes 5 being used to cooperate with locking bolts to lock to the hub sequentially;

[0025] It should be noted that both the rim 1 and the cover 2 are made of aluminum alloy. While maintaining structural strength, the weight is reduced, which can effectively reduce the connection torque when connected to the wheel hub during high-speed rotation, thereby improving the anti-detachment ability. A decorative plate 6 is set in the center of the cover 2. The decorative plate 6 is used to etch the electric vehicle brand logo to satisfy the decorative function of the hub cover on the wheel hub.

[0026] like Figure 1 and Figure 3 As shown, a bead seat 7 is provided at the top of the rim 1. The height of the top of the bead seat 7 is greater than the height of the top of the cover 2. A groove 8 is provided in the center of the cover 2. The pre-locking hole 4 and the locking hole 5 are both located inside the groove 8.

[0027] Five pre-locking holes 4 are evenly arranged along the circumference inside the groove 8. The diameter of the pre-locking holes 4 is smaller than the diameter of the locking holes 5. Both the pre-locking holes 4 and the locking holes 5 have internal interfaces at their top ends.

[0028] It should be noted that, since the bead seat 7 is located inside the wheel hub after installation, and the top of the bead seat 7 is higher than the height of the cover 2, and the pre-locking hole 4 and the locking hole 5 of the bead seat 7 for installing the locking bolt are both located inside the groove 8, the tops of the pre-locking hole 4 and the locking hole 5 are located inside the inner interface after the locking bolt is installed. Therefore, after the hub cover is installed with the wheel hub, the cover 2 is located inside the wheel body. This can effectively prevent the electric vehicle from colliding with objects on the outside of the vehicle during movement, thereby reducing the risk of the hub cover loosening due to collision and improving installation stability.

[0029] Furthermore, when connecting the hubcap to the wheel hub, the hubcap is first pre-installed by installing smaller locking bolts in each pre-locking hole 4, and then larger locking bolts are used to fix it through the locking hole 5. After installation, the alternating and evenly installed locking bolts of different sizes can effectively connect the center position of the hubcap to the wheel hub, thereby improving the connection strength of the center position of the hubcap and improving the hubcap's anti-detachment ability.

[0030] like Figure 1 and Figure 4 As shown, the cover 2 is evenly provided with eight spokes 3 along the circumference. Two spokes 31 are provided on the side of the spokes 3 near the rim 1. An outer lock seat 32 is provided on the inner side of each of the two spokes 31. An outer lock bolt 33 is installed inside the outer lock seat 32.

[0031] The two adjacent outer locking bolts 33 and the two spokes 31 form an isosceles triangle, with one end of the outer locking bolt 33 penetrating the rim 1 (see...). Figure 2 ) Connected to the wheel hub;

[0032] It should be noted that the eight spokes 3 evenly arranged along the circumference can effectively maintain the stability of the hub cover during rotation. The two spokes 31 at the ends of the spokes 3, together with the two external locking bolts 33, form an isosceles triangle structure, which can change the stable support structure of the edge of the hub cover from the existing strip structure to a more stable triangular structure, thereby further improving its rotational stability and enhancing the anti-detachment effect. Furthermore, since each spoke 31 has an external locking seat 32 with an external locking bolt 33 on its inner side, and the external locking bolt 33 can further strengthen the structure of the edge of the hub cover through the connection between the external locking seat 32 and the hub, combined with the strong locking of the center position of the hub cover, the overall connection stability and connection strength between the hub cover and the hub are higher, thus forming an integrated anti-detachment solution with dual locking of the center and edge positions when the hub cover is connected to the hub.

[0033] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
