[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0030] The embodiment of the present application solves the technical problem in the prior art that the connecting rod shaft of the electric pedal is easily infiltrated with sand and water by providing an electric pedal protection structure.

[0031] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows:

[0032] like Figure 1 、 Figure 2 、 Figure 5 As shown, the present application provides an electric pedal protection structure, comprising:

[0033] A bottom plate 1, on which a side plate 2 is fixedly mounted, and a through hole 3 is formed in the side plate 2;

[0034] a connecting rod shaft 4, wherein the connecting rod shaft 4 passes through the through hole 3;

[0035] The bushing 5 and the dust cover 6 are inserted from both sides of the through hole 3 and matched. In this embodiment, the bushing 5 and the dust cover 6 are connected by threaded matching. A first sealing ring 7 is provided inside the bushing 5. The first sealing ring 7 can be a star-shaped sealing ring. A port is provided at the outer end of the bushing 5. The connecting rod shaft 4 is inserted into the bushing 5 through the port. An inner groove 51 is provided at one end of the bushing 5 close to the port. The first sealing ring 7 is provided in the inner groove 51.

[0036] The connecting rod shaft 4 is inserted into the bushing 5, one end of the bushing 5 is sealed by a dust cover 6, and the through hole 3 at the other end of the bushing 5 and the connecting rod shaft 4 are sealed by a first sealing ring 7 to prevent water and sand from entering both ends of the bushing 5. The structure is simple and the service life of the electric pedal is extended.

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0038] Preferably, if Figure 2 、 Figure 3 As shown, an oil groove 52 is provided on the inner side of the bushing 5, and the oil groove 52 is spirally arranged along the axial direction of the bushing 5; a groove 61 is provided on the inner bottom surface of the dust cover 6, and a second sealing ring 62 is provided in the groove 61. The second sealing ring 62 is in pressure contact with the bushing 5 and the dust cover 6, and the second sealing ring 62 is an O-ring.

[0039] During the rotation of the connecting rod shaft 4, the lubricating oil in the oil groove 52 will lubricate the connecting rod shaft 4 and the bushing 5, increasing the lubrication of the mechanism. The contact position between the dust cover 6 and the inside of the bushing 5 is sealed by the second sealing ring 62 to prevent the lubricating oil from entering the threads of the bushing 5 and the dust cover 6 that cooperate with each other, which may cause the bushing 5 and the dust cover 6 to fall off easily.

[0040] Alternatively, as Figure 4 As shown, matching flattened portions 31 are provided on the inner side of the through hole 3 and the outer side of the bushing 5 . The bushing 5 and the through hole 3 are limited by the flattened portions 31 to prevent the bushing 5 from rotating in the through hole 3 .

[0041] Further, such as Figure 2 As shown, the outer wall of the bushing 5 is provided with a glue groove 53, which can be filled with glue. The glue groove 53 corresponds to the inner wall of the through hole 3. The glue in the glue groove 53 is tightly bonded to the side wall of the through hole 3, making the connection between the bushing 5 and the through hole 3 more stable. The glue groove 53 can be rectangular, trapezoidal, etc., preferably trapezoidal.

[0042] Preferably, there is a gap between the end of the connecting rod shaft 4 and the dust cover 6, which prevents the connecting rod shaft 4 from rubbing against the dust cover 6 during the rotation of the connecting rod shaft 4, thereby preventing the dust cover 6 from being worn and loosened.

[0043] like Figure 1 、 Figure 5 As shown, an electric pedal protection assembly includes the electric pedal protection structure described in any one of the above technical solutions, the side panels 2 are two oppositely arranged, the through holes 3 on the two side panels 2 are coaxially arranged, the ports of the bushings 5 ​​on the two side panels 2 are oppositely arranged, the dust covers 6 on the two side panels 2 are back to back, and the connecting rod shaft 4 passes through the port of the bushing 5.

[0044] During the installation process, first install the two oppositely arranged bushings 5 ​​in the through hole 3, then insert the connecting rod shaft 4 so that the connecting rod shaft 4 cooperates with the first sealing ring 7, and then install the dust covers 6 on the outer sides of the two side panels 2. The dust covers 6 and the bushings 5 ​​press the second sealing ring 62 tightly, and finally achieve that both sides of the connecting rod shaft 4 and the bushings 5 ​​can prevent sand and water from entering the inside of the bushings 5, thereby realizing the waterproof and sand-proof properties of the connecting rod shaft 4.

[0045] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0046] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
