Description

Technical Field

[0001] The utility model relates to the technical field of switch shaft mechanisms, in particular to a light and thin switch shaft structure for a vehicle traction arm. Background Art

[0002] The existing switch shaft mechanism connects and fixes two objects so that the objects can rotate 360 degrees freely. When connecting the two objects, the rotating shaft needs to pass through one object, which destroys the structure of the object itself. In addition, the axial length is too long and inconvenient to install and use. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the utility model provides a thin switch shaft structure for a vehicle traction arm, which realizes the connection or disconnection between the fixed base plate component and the gear plate component by rotating the main shaft component, and can connect and fix two objects so that the objects can rotate freely 360°.

[0004] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions:

[0005] A thin switch shaft structure for a vehicle traction arm includes a shaft connecting component, a rotating main shaft component, a fixed base component, and a toothed disc component. The rotating main shaft component is movably connected to the shaft connecting component and the fixed base component respectively, the fixed base component is movably connected to the toothed disc component, and the toothed disc component is fixedly connected to the shaft connecting component. The fixed base component is driven by the rotating main shaft component to connect or disconnect the fixed base component and the toothed disc component.

[0006] Furthermore, the rotating shaft connecting component includes a first rotating shaft connecting component and a second rotating shaft connecting component, the first rotating shaft connecting component is movably connected to the rotating main shaft component, and the second rotating shaft connecting component is fixedly connected to the gear disc component.

[0007] Furthermore, a main shaft hole for movably connecting to the rotating main shaft component is provided in the middle of the first rotating shaft connecting member and the second rotating shaft connecting member, and both the first rotating shaft connecting member and the second rotating shaft connecting member are provided with a fixing hole for vehicle towing.

[0008] Furthermore, the rotating main shaft component includes a main shaft component and a rotating connecting component, the main shaft component is fixedly connected to the rotating connecting component, the main shaft component is movably connected to the first rotating shaft connecting component, and the rotating connecting component is movably connected to the fixed base component.

[0009] Furthermore, the rotating connecting member is provided with an arc-shaped hole for movable connection with the fixed base plate member.

[0010] Furthermore, the fixed base plate component includes a fixed pin component and a fixed base component. The fixed pin component is movably connected to the fixed base component and the rotating spindle component respectively, and the fixed base component is movably connected to the gear disc component.

[0011] Furthermore, the fixed bottom component is provided with a groove adapted to the fixed pin component, and the fixed pin component is provided with a pin for movably connecting with the rotating main shaft component.

[0012] Furthermore, the pin slides in the arc-shaped hole of the rotating connecting member, thereby achieving mutual engagement or non-engagement between the fixed pin member and the toothed disc member.

[0013] Furthermore, the toothed disc component is provided with a groove for being movably connected to the fixed base component, that is, the toothed disc component is provided with a groove adapted to the fixed pin component, so that the fixed pin component can be movably connected to the toothed disc component.

[0014] Furthermore, the rotating main shaft component also includes an elastic member, which is movably connected to the main shaft component, and the main shaft component automatically rebounds to its original position due to the elasticity of the elastic member.

[0015] Optionally, the elastic member may be a spring member, and the spring member is mounted on the main shaft member.

[0016] The beneficial effects of the present application are: the fixed base plate component is driven by rotating the main shaft component, so that the fixed base plate component and the toothed disc component are connected or disconnected, and the two objects can be connected and fixed so that the objects can rotate freely 360 degrees.

[0017] The switch shaft structure is lightweight and thin, achieving a thickness of only 16mm. It connects two concentrically rotating objects through a surface connection. A mechanical switch controls the rotation angle of the two connected parts. Within 360° of rotation, the number of grooves in the toothed disc can be set to achieve a fixed position every 15°.

[0018] By utilizing the engagement of the fixing pin member with the groove of the toothed disc member and setting the number of fixing pin members according to actual usage, the locking firmness is ensured, the shear stress can reach more than 100N, and single-sided fixation between two rotating objects can be achieved.

[0019] In a limited space, while ensuring mechanical strength, the installation thickness is minimized to ≤20mm. The internal structure design, when the thickness is determined, uses the main shaft to twist 90°, driving the fixed pin to shrink 5mm toward the axis, completing the design of the locking mechanism.

[0025] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] The following describes the implementation of the present invention through specific concrete examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The present invention can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Example 1:

[0028] A thin switch shaft structure for a vehicle traction arm includes a shaft connecting component, a rotating main shaft component, a fixed base component, and a toothed disc component. The rotating main shaft component is movably connected to the shaft connecting component and the fixed base component respectively, the fixed base component is movably connected to the toothed disc component, and the toothed disc component is fixedly connected to the shaft connecting component. The fixed base component is driven by the rotating main shaft component to connect or disconnect the fixed base component and the toothed disc component.

[0029] The rotating shaft connecting member includes a first rotating shaft connecting member and a second rotating shaft connecting member. The first rotating shaft connecting member is movably connected to the rotating main shaft member, and the second rotating shaft connecting member is fixedly connected to the gear plate member. The first rotating shaft connecting member and the second rotating shaft connecting member are provided with a main shaft hole in the middle portion thereof for movably connecting to the rotating main shaft member. The first rotating shaft connecting member and the second rotating shaft connecting member are both provided with a fixing hole for vehicle towing. The number and position of the fixing holes on the first rotating shaft connecting member and the second rotating shaft connecting member can be set according to the specific actual use situation. Simply increasing or decreasing the number of fixing holes and changing the position of the fixing holes are all within the scope of protection of this application.

[0030] The rotating main shaft component is movably connected to the rotating shaft connecting component and the fixed base component respectively. The rotating main shaft component includes a main shaft component and a rotating connecting component. The main shaft component is fixedly connected to the rotating connecting component, the main shaft component is movably connected to the first rotating shaft connecting component, and the rotating connecting component is movably connected to the fixed base component. The rotating connecting component is provided with an arc-shaped hole for movably connecting to the fixed base component.

[0031] The fixed base member is movably connected to the toothed disc member and includes a fixed pin member and a fixed base member. The fixed pin member is movably connected to the fixed base member and the rotating spindle member, respectively, and the fixed base member is movably connected to the toothed disc member. The fixed base member is provided with a groove adapted to mate with the fixed pin member, and the fixed pin member is provided with a pin for movably connecting to the rotating spindle member. The diameter of the pin of the fixed pin member is smaller than the size of the arcuate hole of the rotating connector, so that the pin slides within the arcuate hole of the rotating connector, achieving mutual engagement or non-engagement between the fixed pin member and the toothed disc member.

[0032] The toothed disc component is movably connected to the fixed base component, and the toothed disc component is fixedly connected to the rotating shaft connecting component. The toothed disc component is provided with a groove for movably connecting to the fixed base component. Specifically, the toothed disc component is provided with a groove that is compatible with the fixed pin component, enabling the fixed pin component to movably connect to the toothed disc component. The number and position of the grooves in the toothed disc component can be set according to specific actual usage. Simply increasing or decreasing the number of grooves in the toothed disc component or changing the position of the grooves in the toothed disc component falls within the scope of protection of this application.

[0033] When in use, by twisting the main shaft member of the rotating main shaft member, the rotating connecting member of the rotating main shaft member drives the fixed pin member of the fixed base plate member to extend outward from the axis or contract inward from the axis, so that the fixed pin member is movably connected to the fixed base member and the rotating main shaft member respectively, thereby realizing the connection or disconnection between the fixed base plate member and the gear disk member.

[0034] Example 2:

[0035] This embodiment differs from the first embodiment in that the rotating main shaft component of the thin switch shaft structure for a vehicle towing arm further includes an elastic member that is movably connected to the main shaft component, and the elasticity of the elastic member causes the main shaft component to automatically rebound to its original position. Alternatively, the elastic member may be a spring member that is mounted on the main shaft component, and the elasticity of the spring member causes the main shaft component to automatically rebound to its original position.

[0036] For example, when in use, the main shaft of the main shaft component is twisted and rotated, and the rotating connecting member of the rotating main shaft component drives the fixed pin component of the fixed base component to shrink in the direction of the axis center, and the fixed pin component and the groove of the gear plate component are meshed with each other, so that the gear plate component and the first rotating shaft connecting member are synchronously rotated 360 degrees along the main shaft component concentrically. 0 When the main shaft is released, the main shaft automatically rebounds to its original position by virtue of the elasticity of the elastic member, so that the fixed pin member and the toothed disc member are re-engaged and locked, so that the toothed disc member and the first rotating shaft connecting member cannot rotate along the main shaft.
