[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0022] As shown in the figure, Figures 1 to 5 An electronic mechanical brake device applied to a car comprises a frame 1, a support 2 connected to the frame 1, two frame shafts 3 connected to the frame 1, and a guide pin 10 installed in the frame shaft 3, two protective shells 5 are connected to the outer sides of the two guide pins 10, a fixed ring 4 is fixedly installed on the outer sides of the two frame shafts 3, a slot 401 is formed in the fixed ring 4, the protective shell 5 is inserted and arranged in the slot 401, and a limiting half ring 15 abutting against the outer side of the top of the guide pin 10 is fixedly connected to the inner wall of the other end of the protective shell 5.
[0023] As shown in the figure, Figure 1 The electronic mechanical brake device applied to a car in the utility model is similar in structure to the existing electronic mechanical brake device. For example, a patent with the publication number CN221145123U discloses an electronic mechanical brake device. The main improvement of the utility model lies in that the rubber sleeve is provided with a protective structure. As shown in the figure, Figures 1 to 5 When the guide pin 10 needs to be moved on the frame shaft 3 under the power of the support 2, the limiting half ring 15 of the inner wall of the protective shell 5 will be attached to the outer wall of the guide pin 10, the limiting half ring 15 can facilitate the linear motion of the guide pin 10, the guide pin 10 can smoothly slide between the two protective shells 5, the guide pin 10 and the rubber sleeve are protected inside, and the problem of abrasion of the rubber sleeve caused by foreign matters is effectively prevented when the car is running, and the rubber sleeve is further reduced.
[0024] When the guide pin 10 needs to be disassembled, the protective shell 5 can be taken out from the slot 401 of the fixed ring 4, the two protective shells 5 are taken off, and then the guide pin 10 can be taken out.
[0025] As shown in the figure, Figure 3 and Figure 4 The fixed ring 4 is provided with an adjusting groove 402 in communication with the slot 401, an insertion rod 11 is inserted and arranged in the adjusting groove 402, a threaded ring 14 is threadedly connected to one end of the insertion rod 11 outside the adjusting groove 402, and a tool groove is formed in the outer wall of the threaded ring 14.
[0026] Specifically, when the protective shell 5 needs to be installed with the fixing ring 4, the insertion rod 11 at the bottom of the protective shell 5 is inserted into the adjusting groove 402 from the insertion slot 401. Since the adjusting groove 402 is an arc-shaped groove, the protective shell 5 can be adjusted to make the inner wall of the limiting half ring 15 and the outer wall of the guide pin 10 reasonably fit. After the protective shell 5 is adjusted, the threaded ring 14 is screwed with the insertion rod 11, and the insertion rod 11 is fixed by using friction, so that the protective shell 5 is fixed.
[0027] As shown in Figure 2 , Figure 3 and Figure 4 , the outer side of the two protective shells 5 is annularly provided with a scraping ring 8, and the top outer side of the frame shaft 3 is fixedly provided with an electric telescopic rod 7. The output end of the electric telescopic rod 7 is fixedly connected with the outer wall of the scraping ring 8 through a connecting rod 13, and the scraping ring 8 is slidingly connected with the outer wall of the two protective shells 5.
[0028] Specifically, when the protective shell 5 is in use, the outer side may be attached with mud and the like. At this time, the electric telescopic rod 7 can be started, and the output shaft of the electric telescopic rod 7 can push the connecting rod 13 to drive the scraping ring 8 to slide on the outer side of the protective shell 5. In this way, the mud on the outer side of the protective shell 5 can be cleaned.
[0029] The electric telescopic rod 7 here can be connected with the central control system of the car. When it rains, the electric telescopic rod 7 can be directly started for operation. The electric telescopic rod 7 is a mature existing technology, so it will not be described in detail here.
[0030] As shown in Figure 2 , Figure 3 and Figure 5 , the top outer side of the frame shaft 3 is fixedly provided with a mounting shell 6, and the electric telescopic rod 7 is located in the mounting shell 6.
[0031] Specifically, the mounting shell 6 can facilitate the operation of the electric telescopic rod 7.
[0032] As shown in Figure 4 , the outer wall of both ends of one of the protective shells 5 is provided with a sliding groove 12, and the outer wall of both ends of the other protective shell 5 is fixedly connected with an insertion strip 16 corresponding in position to the sliding groove 12.
[0033] Specifically, when the protective shell 5 is installed, the insertion strip 16 can be inserted with the sliding groove 12, so as to ensure the stable connection between the two protective shells 5.
[0034] As shown in Figure 4 , the cross section of the insertion strip 16 and the sliding groove 12 is T-shaped or wedge-shaped. By using T-shaped or wedge-shaped arrangement, the connection between the two can be stable and will not be separated horizontally.
[0035] As shown in Figures 2 to 5As shown in the drawings, the outer side of the protective shell 5 is provided with a ventilation groove 9. The ventilation groove 9 can facilitate ventilation of the protective shell 5, and the opening diameter of the ventilation groove 9 gradually decreases from outside to inside, which can effectively reduce the probability of direct splashing of the silt into the protective shell 5, and the ventilation groove 9 should be arranged at the top to further reduce the splashing of the silt into the protective shell 5.
[0036] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
