Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a waterproof and sandproof electric pedal. Background Technology

[0002] With the rapid development of automotive electronics technology, the comfort and richness of vehicle functions are constantly improving. As a convenient device for getting in and out of vehicles, electric pedals bring convenience to people's lives, but they also face urgent demands for comfort, safety, and stability.

[0003] Currently, traditional electric pedals use only one bushing at the linkage shaft, which is insufficient for waterproofing and sandproofing. Water and sand ingress can cause abnormal noises, uneven extension and retraction, and in severe cases, pedal jamming, leading to accidents. As electric pedals are used over time, the bushing wears down, increasing the gap between the linkage shaft and the bushing, resulting in play, abnormal noises, and increased susceptibility to water and sand ingress. Utility Model Content

[0004] This application provides a waterproof and sandproof electric pedal, which solves the technical problem that water and sand can easily enter the pedal in the prior art.

[0005] This application provides a waterproof and sandproof electric pedal, including a motor with a motor shaft; a base plate with a shaft hole through which the motor shaft passes, the motor being detachably connected to the underside of the base plate; a motor shaft detachably connected to the motor shaft; and a dust cover with a through hole matching the motor shaft, the dust cover being detachably connected to the upper side of the base plate, a first sealing ring between the dust cover and the base plate, a second sealing ring between the motor and the base plate, and a third sealing ring between the inner wall of the through hole of the dust cover and the motor shaft, thereby making it difficult for external water and sand to enter the interior of the waterproof and sandproof electric pedal.

[0006] Furthermore, it also includes a motor shaft, which is detachably connected to the motor shaft.

[0007] Furthermore, a first groove is provided on the upper side of the base plate, and the first sealing ring is disposed in the first groove; a second groove is provided on the lower side of the base plate, and the second sealing ring is disposed in the second groove.

[0008] Furthermore, the dust cover is also equipped with a first bearing and a second bearing, and the motor shaft is configured to cooperate with the first bearing and the second bearing.

[0009] Furthermore, the first bearing is disposed on the upper part of the motor shaft, and the second bearing is disposed on the lower end of the motor shaft.

[0010] Furthermore, the second bearing has a larger size than the first bearing.

[0011] Furthermore, it also includes a locking block, which has a threaded hole in the axial direction, and the motor shaft has a matching connection hole, and the locking block is threadedly connected to the motor shaft.

[0012] Furthermore, the locking block is provided with a first flat position, and the motor shaft is provided with a second flat position that matches the locking block, thereby realizing the locking of the motor shaft with the motor shaft.

[0013] Furthermore, the dust cover is made of metal.

[0014] Furthermore, all of the sealing rings are O-rings.

[0015] The beneficial effects of this application are as follows:

[0016] Because the electric pedal has sealing rings at multiple key locations, it is difficult for external water and sand to enter the electric pedal, resulting in a better user experience, a longer service life, and less likelihood of abnormal noise.

[0017] In addition, this waterproof and sandproof electric pedal uses bearings, which makes the motor shaft run more smoothly and is less prone to wear. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0034] This application provides a solution to the technical problem in the prior art where water and sand easily enter the interior of electric pedals.

[0035] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this application provides a waterproof and sandproof electric pedal, including a motor 2 with a motor shaft 3; a base plate 1 with a shaft hole 19 through which the motor shaft 3 passes, and the motor 2 is detachably connected to the lower side of the base plate 1; a motor shaft 4 detachably connected to the motor shaft 3; and a dust cover 5 with a through hole 20 matching the motor shaft 4, through which the motor shaft 4 passes, and the dust cover 5 is detachably connected to the upper side of the base plate 1. A first sealing ring 6 is provided between the dust cover 5 and the base plate 1, a second sealing ring 7 is provided between the motor 2 and the base plate 1, and a third sealing ring 8 is provided between the inner wall of the through hole 20 of the dust cover 5 and the motor shaft 4. This effectively prevents external water and sand from entering the internal structure of the electric pedal through the gaps, thereby achieving waterproof and sandproof protection for the internal structure of the electric pedal.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] Preferably, a first groove 17 is provided on the upper side of the base plate 1, and a first sealing ring 6 is provided in the first groove 17. The first sealing ring 6 is in pressure contact with the lower part of the dust cover 5, thereby preventing external water and sand from entering the structure from the gap between the dust cover 5 and the upper side of the base plate 1.

[0039] Meanwhile, a second groove 18 is provided on the lower side of the base plate 1, and a second sealing ring 7 is provided in the second groove 18. The second sealing ring 7 is in pressure contact with the contact surface of the motor 2, thereby preventing external water and sand from entering the structure from the connection gap between the base plate 1 and the motor 2.

[0040] Furthermore, the dust cover 5 is also provided with a first bearing 9 and a second bearing 10. The inner diameters of the first bearing 9 and the second bearing 10 match the outer diameter of the motor shaft 4. The motor shaft 4 passes through the first bearing 9 and the second bearing 10 and is fitted together, so that the motor shaft 4 rotates smoothly and is not easily worn, reducing the frequency of replacement parts.

[0041] Meanwhile, the first bearing 9 is located on the upper part of the motor shaft 4, and the second bearing 10 is located on the lower end of the motor shaft 4. The size of the second bearing 10 is larger than that of the first bearing 9, thereby enhancing the stability of the shaft rotation.

[0042] Preferably, such as Figure 7 , Figure 8 As shown, the electric pedal also includes a locking block 11, the locking block 11 having an axially arranged threaded hole 16, and the motor shaft 4 having a matching connecting hole 21. The locking block 11 passes through the connecting hole 21 and is fixed by a first fastener 111, thereby realizing a threaded connection between the locking block 11 and the motor shaft 4.

[0043] Meanwhile, the locking block 11 is provided with a first flat position 15, and the motor shaft 3 is provided with a second flat position 14 that matches the locking block 11. After the locking block 11 and the motor shaft 4 are fixed by the first fastener 111, the locking block 11 engages with the motor shaft 3, thereby locking the motor shaft 4 and the motor shaft 3, so that the motor shaft 4 and the motor shaft 3 rotate synchronously, which is convenient for maintenance. Moreover, the connection between the motor shaft 4 and the motor shaft 3 is firm and not easy to loosen, which increases safety.

[0044] Of course, the motor shaft 3 and the motor shaft 4 can be connected in various ways. The motor shaft 3 is provided with one or more threaded holes, and the motor shaft 4 is provided with corresponding connecting holes. The motor shaft 3 and the motor shaft 4 are threadedly connected by fasteners, which can also achieve the fastening of the connection between the motor shaft 3 and the motor shaft 4. The fasteners are block-shaped metal.

[0045] like Figure 6 As shown, optionally, the dust cover 5 is made of metal to protect the internal structure of the electric pedal.

[0046] Preferably, all the sealing rings are O-rings.

[0047] like Figure 9 , Figure 10 , Figure 11As shown, during installation, a second sealing ring 7 is placed in the second groove 18 on the lower side of the base plate 1. The motor shaft 3 passes through the shaft hole 19 of the base plate 1. The motor 2 is threadedly connected to the lower side of the base plate 1 with screws, pressing the second sealing ring 7. The second bearing 10 passes through the motor shaft 3 and is placed on the upper side of the base plate 1. The motor shaft 4 passes through the motor shaft 3. The lower end of the motor 2 passes through the matching second bearing 10. The motor shaft 3 and the motor shaft 4 are detachably connected by a locking block 11 and locked together. A first sealing ring 6 is placed in the first groove 17 on the upper side of the base plate 1. The first bearing 9 is installed on the upper part of the motor shaft 4. The third sealing ring 8 is placed on the top of the inner side of the dust cover 5. The through hole 20 of the dust cover 5 passes through the motor shaft 4. The bottom of the dust cover 5 is threadedly connected to the upper side of the base plate 1. The third sealing ring 8 is in close contact with the motor shaft 4. The first sealing ring 6 is in pressure contact with the dust cover 5, thereby achieving waterproof and sandproof protection for the electric pedal.
