Description

Technical Field

[0001] This utility model belongs to the technical field of starter parts, specifically relating to an automobile starter fork. Background Technology

[0002] The shift fork is a core component of the automotive transmission control mechanism. Through its structural design that straddles the annular groove of the sliding gear, it enables the transmission connection between the shift lever and the gear. In modern vehicles, the shift fork is pulled by a magnetic switch, causing the angle of the shift fork to change, which in turn drives the other end of the shift fork to change the position of the swing wheel, thus starting the engine.

[0003] Existing shift forks are generally integrally machined workpieces, mainly composed of a rotating frame, a connecting end, and a push column. The push column and the connecting end are respectively installed at both ends of the rotating frame. The end of the push column is connected to the inner wall of the swing wheel. As the position of the connecting end changes, the rotating frame drives the push column to push the swing wheel.

[0004] Although the aforementioned shift fork can push the swing wheel to move, in actual use, the distance between the end of the magnetic switch and the swing wheel is not equal to the length of the shift fork itself. This directly causes the contact end between the shift fork and the swing wheel to not be on the central axis of the swing wheel itself. As a result, when the shift fork pushes the swing wheel, the two sides of the swing wheel are subjected to uneven force, and the friction between the inner wall of the swing wheel and the support rod is severe, affecting the service life of the overall component.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0007] An automotive starter fork includes a main fork body, a connecting plate, and a push assembly. The push assembly is installed at one end of the main fork body, and the connecting plate is installed at the other end of the main fork body. The connecting plate is connected to the end of a magnetic switch. The push assembly is sleeved on the outside of a swivel wheel. An adjustment mechanism is installed at the end of the main fork body. The adjustment mechanism includes a rotating block, a moving end, and a lead screw. A moving hole is opened in the main fork body. The moving end is slidably installed in the moving hole. The lead screw is rotatably installed in the moving hole. The lead screw is threadedly engaged with the moving end. A rotating block is installed at the end of the lead screw. The moving end is connected to the push assembly.

[0008] As a preferred embodiment of this utility model, the length of the moving end is less than the length of the moving groove, and the moving hole penetrates through the end of the main fork body.

[0009] As a preferred technical solution of this utility model, the pushing component includes a limiting rod, a connecting seat, a contact end, a fixing screw, and a connecting arm. Connecting arms are symmetrically installed on both sides of the moving end, a connecting seat is installed at the top of the connecting arm, a limiting rod is installed inside the connecting seat, a contact end is installed at the end of the limiting rod, and a fixing screw is threadedly installed on the contact end and the side of the limiting rod.

[0010] As a preferred embodiment of this utility model, the contact end is composed of an arc-shaped push plate and a fixed seat, with a fixed seat installed at the bottom of the limiting rod and an arc-shaped push plate installed at the end of the fixed seat.

[0011] As a preferred technical solution of this utility model, the fixed seat and the end of the limiting rod are both provided with a meshing groove, and the meshing groove is threadedly connected to the fixed screw.

[0012] As a preferred technical solution of this utility model, the main fork body includes a support plate, a fixed arm, a threaded rod and a nut. The support plates are symmetrically arranged between the connecting plate and the pushing assembly. The two sets of support plates are in close contact with each other. The fixed arm is installed at the end of the support plate and is connected to the connecting plate. The threaded rod is installed inside the support plate and passes through the two sets of support plates. The nut is threaded at the end of the threaded rod.

[0013] As a preferred embodiment of this utility model, the support plate has a insertion hole at its middle end, which is connected to the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the adjustment mechanism utilizes the rotation of the lead screw to adjust the position of the pushing component, precisely adjusting the overall length of the shift fork so that the contact end is stably attached to the outside of the swing wheel, and the contact end is located on the central axis of the swing wheel. This avoids uneven force distribution on both sides of the swing wheel due to misalignment of the contact end, ensuring the stability of the shift fork during use. Furthermore, the arc-shaped contact plate at the contact end expands the contact area between the shift fork and the swing wheel, reducing the compressive strength on the swing wheel and ensuring the working quality of the swing wheel during use.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0024] like Figure 1 and Figure 2 As shown, it is a structural schematic diagram of the car starter fork in this embodiment. The fork includes a main fork body 1, a connecting plate 2 and a pushing component 3. The pushing component 3 is installed at one end of the main fork body 1, and the connecting plate 2 is installed at the other end of the main fork body 1. The connecting plate 2 is connected to the end of the magnetic switch. The pushing component 3 is sleeved on the outside of the swing wheel. An adjustment mechanism 4 is installed at the end of the main fork body 1.

[0025] In use, select the appropriate size shift fork according to the starter's specifications, and then place the shift fork between the magnetic switch and the swivel wheel in the starter. Due to the inherent deviations of various workpieces, the distance between the magnetic switch and the swivel wheel is not directly equal to the length of the shift fork itself. At this time, by using the adjustment mechanism 4, the position of the push component 3 at the end of the main fork body 1 is finely adjusted so that the contact point between the push component 3 and the swivel wheel is located on the central axis of the swivel wheel, making the contact surface between the push component 3 and the swivel wheel more accurate, which facilitates the subsequent pushing of the swivel wheel position.

[0026] As attached Figure 3 As shown, this is a schematic diagram of the structure of the adjustment mechanism 4 in this embodiment. The adjustment mechanism 4 includes a rotating block 41, a moving end 42, and a lead screw 43. A moving hole is provided in the main fork body 1. The moving end 42 is slidably installed in the moving hole, and the lead screw 43 is rotatably installed in the moving hole. The lead screw 43 is threadedly engaged with the moving end 42. The rotating block 41 is installed at the end of the lead screw 43. The moving end 42 is connected to the pushing component 3. The length of the moving end 42 itself is less than the length of the moving groove, and the moving hole penetrates through the end of the main fork body 1.

[0027] Based on the distance between the end of the magnetic switch and the swing wheel, place the main fork 1 between the magnetic switch and the swing wheel, and connect the connecting plate 2 to the end of the magnetic switch. At this time, by rotating the rotating block 41, the moving end 42 outside the lead screw 43 moves along the thread direction on the lead screw 43, and the position of the pushing component 3 is finely adjusted so that the contact surface between the pushing component 3 and the swing wheel is on the central axis of the swing wheel.

[0028] As attached Figure 4 As shown, this is a schematic diagram of the structure of the pushing component 3 in this embodiment. The pushing component 3 includes a limiting rod 31, a connecting seat 32, a contact end 33, a fixing screw 34, and a connecting arm 35. The connecting arms 35 are symmetrically installed on both sides of the moving end 42. The connecting seat 32 is installed at the top of the connecting arm 35. The limiting rod 31 is installed inside the connecting seat 32. The contact end 33 is installed at the end of the limiting rod 31. The contact end 33 is composed of an arc-shaped pushing plate and a fixing seat. The fixing seat is installed at the bottom of the limiting rod 31. The arc-shaped pushing plate is installed at the end of the fixing seat. The fixing seat and the end of the limiting rod 31 are provided with a meshing groove. The meshing groove is threadedly connected to the fixing screw 34.

[0029] In use, insert the limiting rod 31 into the connecting seat 32, then align the fixing seat with the end of the limiting rod 31, and then lock the position of the limiting rod 31 and the fixing seat by using the fixing screw 34. After that, align the bottom end of the contact end 33 with the swing wheel so that the contact end 33 can push the swing wheel to slide after the overall angle of the shift fork is tilted.

[0030] As attached Figure 5 As shown, this is a structural schematic diagram of the main fork body 1 in this embodiment. The main fork body 1 includes a support plate 11, a fixed arm 12, a threaded rod 13, and a nut 14. The support plates 11 are symmetrically arranged between the connecting plate 2 and the pushing assembly 3. The two sets of support plates 11 are fitted together. The fixed arm 12 is installed at the end of the support plate 11 and is connected to the connecting plate 2. The threaded rod 13 is installed inside the support plate 11 and passes through the two sets of support plates 11. The nut 14 is threaded at the end of the threaded rod 13. The middle of the support plate 11 is provided with a plug hole, which is connected to the rotating shaft.

[0031] In use, the two sets of support plates 11 are attached together, and then the positions of the two sets of support plates 11 are locked and fixed by using the threaded rod 13 and nut 14. Through the connection of the fixing arm 12, when the connecting plate 2 is pulled by the magnetic switch, the main fork body 1 rotates around the rotating shaft as the axis, adjusting the angle and position of the pushing component 3, so that the pushing component 3 pushes the position of the swing wheel.

[0032] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
