Description

Technical Field

[0001] The invention belongs to the technical field of shock absorber dust covers, and in particular relates to a dust cover structure of an electronically controlled shock absorber. Background Art

[0002] The dust cover is a crucial component of the shock absorber. Its primary function is to prevent dust, water, and other foreign matter from entering the shock absorber, thereby protecting the piston rod and extending its service life. Structurally, the dust cover is integrated with the shock absorber's upper support, and some include a metal frame for enhanced strength and stability. Functionally, the dust cover not only prevents sand, dust, and dirty water from entering the upper support but also allows the piston rod to freely extend and retract during movement.

[0003] Prior art patent applications, including one titled "A shock absorber dust cover, shock absorber assembly, and vehicle," with authorization publication number CN213064600U, and another titled "A shock absorber dust cover," with authorization publication number CN216618371U, disclose dust covers that are open only at the lower end, fully covering the upper end of the shock absorber. However, for shock absorbers with built-in solenoid valves, the wiring harness must pass through the dust cover, making these prior art dust covers unsuitable.

[0004] Therefore, the present application provides a dust cover that facilitates the passage of a wiring harness to adapt to the use of a built-in solenoid valve shock absorber. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a dust cover structure for an electronically controlled shock absorber, which is used to solve the technical problem that the current dust cover lacks openings for the wiring harness to pass through and is not suitable for built-in solenoid valve shock absorbers.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is: a dust cover structure of an electronically controlled shock absorber, the dust cover structure comprising an end cover connected to the upper support of the shock absorber and a cover cover detachably connected to the end cover, the end cover comprising an annular lower side plate for covering the outside of the upper support connection hole, a clamping portion connected to the lower side plate, and an annular upper side plate connected to the end of the lower side plate, one side of the upper side plate is obliquely extended upward with an overhang portion, the end of the overhang portion is provided with a lower half hole; the lower opening of the cover cover matches the shape of the upper side plate and the overhang portion, and the cover cover is aligned with the position of the lower half hole and provided with an upper half hole; when the cover cover is connected to the end cover, the lower half hole and the upper half hole are combined to form a through hole for the wiring harness to pass through.

[0007] Preferably, the end of the overhang portion is provided with two layers of lower end plates with gap distribution, and the lower half holes are provided at corresponding positions on the lower end plates on both sides.

[0008] Preferably, the cover is provided with an upper end plate aligned with the gap between the two lower end plates, and the upper half hole is provided on the upper end plate; when the cover is connected to the end cover, the upper end plate is embedded between the two lower end plates.

[0009] Preferably, a snap-fit structure is used between the cover and the end cover to achieve detachable connection.

[0010] Preferably, the snap-fit structure includes a snap-fit protrusion provided on the side wall of the end cover and a snap-fit groove provided on the side wall of the cover.

[0011] Preferably, the clamping portion includes a plurality of clamping claws arranged along circumferential gaps, and a limiting protrusion is provided on the outer side of the clamping claws.

[0012] The beneficial effects of adopting the technical solution of the present invention are: The dust cover of the present invention comprises a detachable end cap and a cover. The cover can be removed from the end cap when needed, facilitating maintenance and inspection. An overhang portion extends obliquely upward from one side of the end cap, with a lower half hole provided at the end of the overhang portion. An upper half hole is provided on the side wall of the cover cap at a position corresponding to the lower half hole. When the cover cap is attached to the end cap, the upper and lower half holes combine to form a through hole for a wiring harness to pass through, thereby providing for a built-in solenoid valve-type shock absorber. Furthermore, the through hole for the wiring harness to pass through is provided on the side wall, rather than on the top, reducing the possibility of liquid intrusion into the dust cover through the through hole and improving the dust and water resistance.

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and do not limit the scope of the present invention.

[0016] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0017] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0018] The specific embodiments are as follows: like Figure 1-3 As shown, a dust cover structure of an electronically controlled shock absorber includes an end cover 1 and a cover 2. The end cover 1 includes a lower side plate 12, a clamping portion 14, an upper side plate 13 and an overhang 11. The lower side plate 12 is annular and fits the shape of the top of the upper support as a whole, and is used to cover the top of the upper support. The clamping portion 14 is connected to the inner wall of the lower side plate 12 and is annular, with the shock absorber piston rod passing through the middle of the ring. The upper side plate 13 is annular and is connected to the upper end of the lower side plate 12. An overhang 11 extends obliquely upward on one side of the upper side plate 13, and the upper side surface of the overhang 11 is open. The higher end of the overhang 11 is provided with a lower half hole 112. In this embodiment, the lower side plate 12, the clamping portion 14, the upper side plate 13 and the overhang 11 are provided as an integrated arrangement.

[0019] The lower opening of the cover 2 matches the contours of the upper side plate 13 and the overhang 11. The cover is positioned outside the upper side plate 13 and the overhang 11, and is removably connected to the end cap 1. An upper hole 22 is provided on the side wall of the cover 2, corresponding to the lower hole 112. When the cover 2 is attached to the end cap 1, the upper hole 22 and the lower hole 112 enclose a through hole for the wiring harness to accommodate the built-in solenoid valve shock absorber.

[0020] Furthermore, a vertical lower end plate 111 is provided at the higher end of the overhang portion 11. The lower end plate 111 is provided with two sides to enhance the waterproof effect, and a gap is provided between the lower end plates 111 on both sides. A lower half hole 112 is provided on each of the lower end plates 111 on both sides.

[0021] Furthermore, a downward-facing upper end plate 21 is provided on the cover 2, with an upper half hole 22 disposed therein. Upper end plate 21 is aligned with the gap between the two lower end plates 111. When the cover 2 is connected to the end cap 1, upper end plate 21 nestles within the gap between the two lower end plates 111, ensuring a tight connection and enhancing waterproof and dustproof properties.

[0022] Furthermore, the cover 2 and end cap 1 are removably connected via a snap-fit structure. More specifically, the snap-fit structure includes a snap-fit protrusion 113 and a snap-fit slot 23. The snap-fit protrusion 113 is disposed on the side wall of the end cap 1, specifically on the upper side plate 13 and the side wall of the overhang 11. The snap-fit slot 23 is disposed on the side wall of the cover 2. The cover 2 is provided with a downwardly extending connecting ear, and the snap-fit slot 23 is disposed on the connecting ear, corresponding to the position of the snap-fit protrusion 113. The deformation of the connecting ear allows the cover 2 to be installed and removed from the end cap 1, facilitating maintenance and inspection.

[0023] Furthermore, the engaging portion 14 includes a plurality of claws arranged with circumferential gaps to allow for a certain degree of deformation, facilitating installation and removal from the upper support. A limiting protrusion is also provided on the outer side of the claw near the lower point, which is used to engage with the connection hole of the upper support and effectively prevent the shock absorber dust cover from loosening.

[0024] When the dust cover structure of the electronically controlled shock absorber of this embodiment is used, the end cover 1 is connected to the connection hole on the upper support through the clamping portion 14. The clamping portion 14 has a claw with a limiting protrusion that limits the connection hole to facilitate installation and removal with the upper support. First, the wiring harness of the solenoid valve is placed across the two lower half holes 112, and then the cover 1 is connected. The upper half hole 22 and the lower half hole 112 are combined to form a complete through hole to enable the wiring harness to pass through the through hole to adapt to the built-in solenoid valve shock absorber. The cover 2 is connected by the card slot 23 and the clamping protrusion 113, and can be repeatedly disassembled and assembled, which is convenient for installation and disassembly, and is convenient for maintenance and inspection. The through hole for the wiring harness to pass through is set on the side wall of the dust cover, rather than at the top, which can effectively reduce the phenomenon of water intruding into the dust cover through the through hole, thereby extending the service life of the shock absorber.

[0025] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
