Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a steering column retaining force structure and a vehicle. Background Technology

[0002] The upper end of the vehicle's steering column is connected to the steering wheel, and the lower end is connected to the steering transmission mechanism. The steering column is used to accurately transmit the driver's steering actions and torque on the steering wheel to the steering transmission mechanism, thereby controlling the vehicle's direction of travel. The steering column retaining force structure can be used to lock or release the steering column, thereby adjusting the position of the steering column and, consequently, the position of the steering wheel.

[0003] The existing steering column retaining force structure is usually a clamp structure, which is fitted onto the steering column and is tightened or loosened by bolts.

[0004] Each time the steering column clamp is tightened or loosened, the nut needs to be repeatedly rotated, causing the threads on the nut and the screw to be in a state of friction for a long time. Under long-term use, the threads are prone to wear and stripping. Furthermore, under the conditions of vehicle vibration and temperature changes, the clamp is prone to loosening, which will cause the clamp to fail to effectively lock the steering column in the later stages, resulting in poor stability of the steering column holding force structure. Utility Model Content

[0005] This application provides a steering column holding force structure and a vehicle to solve the technical problem of poor stability of existing steering column holding force structures.

[0006] A first aspect of this application provides a steering column retaining force structure, comprising:

[0007] A clamp assembly includes a clamp body, a connecting rod, a first limiting member, and a second limiting member. The clamp body is used to be fitted onto the steering column of a vehicle. One end of the connecting rod passes through the first connecting end of the clamp body and is connected to the first limiting member. The first limiting member is used to limit the first connecting end on the connecting rod. The other end of the connecting rod passes through the second connecting end of the clamp body and is connected to the second limiting member. The second limiting member is used to limit the second connecting end on the connecting rod.

[0008] A telescopic assembly is disposed on the connecting rod and located between the second connecting end and the second limiting member. The telescopic assembly is configured such that, when extended, both ends of the telescopic assembly abut against the second limiting member and the second connecting end, respectively, to push the second connecting end closer to the first connecting end, so that the clamping body clamps the steering column; one end of the telescopic assembly disengages from the second limiting member and / or the other end of the telescopic assembly disengages from the second connecting end, so that the second connecting end moves away from the first connecting end, so that the clamping body releases the steering column.

[0009] In one possible implementation, the telescopic component includes a first disc and a second disc, both disposed on the connecting rod. The first disc has at least one groove on its side facing the second disc, the groove comprising a first segment and a second segment, the depth of the first segment being less than the depth of the second segment. The second disc has at least one slider facing the first disc, each slider being slidably connected to the groove in a corresponding manner. The sliders are configured such that, when within the first segment, they increase the distance between the second disc and the first disc, causing the telescopic component to extend; and when within the second segment, they decrease the distance between the second disc and the first disc, causing the telescopic component to shorten.

[0010] In one possible implementation, a first slide rail is provided on the first segment along the extension direction of the first segment, and a second slide rail is provided on the second segment along the extension direction of the second segment. The first slide rail and the second slide rail are connected to form a continuous guide rail. A ball is rotatably disposed on the side of the slider facing the slide groove, and the ball is rotatably connected to the guide rail.

[0011] In one possible implementation, the grooves are arranged in a ring array along the circumference of the first disk.

[0012] In one possible implementation, a first mounting through hole is provided at the center of the first disc body, and a second mounting through hole is provided at the center of the second disc body. The first disc body is sleeved on the connecting rod through the first mounting through hole, and the second disc body is sleeved on the connecting rod through the second mounting through hole.

[0013] In one possible implementation, a handle is also included, which is disposed on the second disc body and is used to drive the second disc body to rotate on the connecting rod so that the slider slides on the groove.

[0014] In one possible implementation, a first elastic limiting member and a second elastic limiting member are respectively provided at both ends of the guide rail, and both the first elastic limiting member and the second elastic limiting member are used to limit the ball.

[0015] In one possible implementation, the first limiting member is a first nut, and the second limiting member is a second nut.

[0016] In one possible implementation, a mounting bracket is further included, on which a first bracket and a second bracket are provided. Both the first bracket and the second bracket are passed through the connecting rod, with the first bracket located between the first limiting member and the first connecting end, and the second bracket located between the second limiting member and the telescopic assembly. The mounting bracket is used to connect to the vehicle body.

[0017] A second aspect of this application provides a vehicle, including:

[0018] Vehicle body;

[0019] The steering column retaining force structure described in any one of the above embodiments is disposed on the vehicle body.

[0020] This application provides a steering column holding force structure and a vehicle. The steering column holding force structure includes a telescopic component between a second connecting end and a second limiting member. When the telescopic component extends, both ends of the telescopic component abut against the second limiting member and the second connecting end, respectively. The telescopic component pushes the second connecting end closer to the first connecting end, causing the second connecting end of the clamp to move closer to the first connecting end. At this time, the clamping force of the clamp on the steering column increases, thus allowing the clamp to hold the steering column. When the telescopic component shortens, one end of the telescopic component disengages from the second limiting member and / or the other end of the telescopic component disengages from the second connecting end, causing the second connecting end to move towards the telescopic component, thus moving the second connecting end away from the first connecting end. At this time, the clamping force of the clamp on the steering column decreases, thus allowing the clamp to release the steering column. In the steering column holding force structure of this application, the clamping or loosening of the steering column can be achieved by the extension and retraction of the telescopic component, thus eliminating the need for threads on the connecting rod, thereby avoiding thread stripping, improving the stability of the clamping body, reducing the probability of the clamping body loosening, and enhancing the stability of the steering column holding force structure.

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent embodiments consistent with this application.

[0048] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are 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, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, and a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0049] The upper end of the vehicle's steering column is connected to the steering wheel, and the lower end is connected to the steering transmission mechanism. The steering column is used to accurately transmit the driver's steering actions and torque on the steering wheel to the steering transmission mechanism, thereby controlling the vehicle's direction of travel. The steering column retaining force structure can be used to lock or release the steering column, thereby adjusting the position of the steering column and, consequently, the position of the steering wheel.

[0050] The existing steering column retaining force structure is usually a clamp structure, which is fitted onto the steering column and is tightened or loosened by bolts.

[0051] Each time the steering column clamp is tightened or loosened, the nut needs to be repeatedly rotated, causing the threads on the nut and the screw to be in a state of friction for a long time. Under long-term use, the threads are prone to wear and stripping. Furthermore, under the conditions of vehicle vibration and temperature changes, the clamp is prone to loosening, which will cause the clamp to fail to effectively lock the steering column in the later stages, resulting in poor stability of the steering column holding force structure.

[0052] To address the poor stability of existing steering column holding force structures, this application proposes a steering column holding force structure and a vehicle. The steering column holding force structure includes a clamp assembly and a telescopic assembly. The clamp assembly includes a clamp body, a connecting rod, a first limiting member, and a second limiting member. The clamp body is fitted onto the steering column of the vehicle. One end of the connecting rod passes through the first connecting end of the clamp body and connects to the first limiting member. The first limiting member limits the first connecting end to the connecting rod. The other end of the connecting rod passes through the second connecting end of the clamp body and connects to the second limiting member. Two limiting members are used to limit the second connecting end on the connecting rod; the telescopic assembly is disposed on the connecting rod and located between the second connecting end and the second limiting member. The telescopic assembly is configured such that, when extended, both ends of the telescopic assembly abut against the second limiting member and the second connecting end respectively, so as to push the second connecting end closer to the first connecting end, so as to make the clamp clamp the steering column; when shortened, one end of the telescopic assembly disengages from the second limiting member and / or the other end of the telescopic assembly disengages from the second connecting end, so as to make the second connecting end move away from the first connecting end, so as to make the clamp release the steering column.

[0053] In the steering column holding force structure of this application, when the telescopic component extends, both ends of the telescopic component abut against the second limiting member and the second connecting end, respectively. The telescopic component can then push the second connecting end closer to the first connecting end, causing the second connecting end of the clamp to move closer to the first connecting end. At this time, the clamping force of the clamp on the steering column increases, thus allowing the clamp to tighten the steering column. When the telescopic component shortens, one end of the telescopic component disengages from the second limiting member and / or the other end of the telescopic component disengages from the second connecting end, causing the second connecting end to move towards the telescopic component, thus moving the second connecting end away from the first connecting end. At this time, the clamping force of the clamp on the steering column decreases, thus allowing the clamp to release the steering column. In the steering column holding force structure of this application, the clamping or releasing of the steering column by the telescopic component can be achieved, thus eliminating the need for threads on the connecting rod, thereby avoiding thread stripping, improving the stability of the clamp, reducing the probability of the clamp loosening, and improving the stability of the steering column holding force structure.

[0054] The technical solution of the application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0056] In the embodiments of this application, reference is made to Figures 1 to 4 As shown, an embodiment of this application provides a steering column retaining force structure, including a clamp assembly 100 and a telescopic assembly 200.

[0057] The clamp assembly 100 includes a clamp body 110, a connecting rod 120, a first limiting member 130, and a second limiting member 140. The clamp body 110 is used to be fitted onto the steering column 10 of the vehicle. One end of the connecting rod 120 passes through the first connecting end 111 of the clamp body 110 and is connected to the first limiting member 130. The first limiting member 130 is used to limit the first connecting end 111 on the connecting rod 120. The other end of the connecting rod 120 passes through the second connecting end 112 of the clamp body 110 and is connected to the second limiting member 140. The second limiting member 140 is used to limit the second connecting end 112 on the connecting rod 120.

[0058] The telescopic assembly 200 is disposed on the connecting rod 120 and located between the second connecting end 112 and the second limiting member 140. The telescopic assembly 200 is configured such that, when extended, both ends of the telescopic assembly 200 abut against the second limiting member 140 and the second connecting end 112 respectively, so as to push the second connecting end 112 closer to the first connecting end 111, so as to make the clamp 110 clamp the steering column 10; when shortened, one end of the telescopic assembly 200 disengages from the second limiting member 140 and / or the other end of the telescopic assembly 200 disengages from the second connecting end 112, so as to make the second connecting end 112 move away from the first connecting end 111, so as to make the clamp 110 release the steering column 10.

[0059] In the steering column retaining force structure of this application, the hoop 110 has a first connecting end 111 and a second connecting end 112. Both the first connecting end 111 and the second connecting end 112 are provided with through holes. One end of the connecting rod 120 passes through the through hole of the first connecting end 111 and is connected to the first limiting member 130. The first limiting member 130 is used to limit the first connecting end 111 on the connecting rod 120 to prevent the first connecting end 111 from detaching from the connecting rod 120. The other end of the connecting rod 120 passes through the through hole of the second connecting end 112 and is connected to the second limiting member 140. The second limiting member 140 is used to limit the second connecting end 112 on the connecting rod 120 to prevent the second connecting end 112 from detaching from the connecting rod 120.

[0060] Specifically, the first limiting member 130 and the second limiting member 140 can be structures such as nuts, baffles, baffles, and protrusions, which can limit the first connecting end 111 and the second connecting end 112 between the first limiting member 130 and the second limiting member 140.

[0061] The telescopic assembly 200 has specific functions of extending and shortening, such as telescopic rods, electric push rods, hydraulic cylinders, pneumatic cylinders, telescopic protrusion assemblies, etc.

[0062] In the steering column holding force structure of this application, when the telescopic component 200 extends, both ends of the telescopic component 200 abut against the second limiting member 140 and the second connecting end 112, respectively. The telescopic component 200 can push the second connecting end 112 closer to the first connecting end 111, causing the second connecting end 112 of the clamp 110 to move closer to the first connecting end 111. At this time, the clamping force of the clamp 110 on the steering column 10 increases, thereby allowing the clamp 110 to clamp the steering column 10. When the telescopic component 200 shortens, one end of the telescopic component 200 disengages from the second limiting member 140 and / or the other end of the telescopic component 200 disengages from the second connecting end 112, causing the second connecting end to move in the direction of the telescopic component 200, so that the second connecting end 112 moves away from the first connecting end 111. At this time, the clamping force of the clamp 110 on the steering column 10 decreases, thereby allowing the clamp 110 to release the steering column 10. In the steering column holding force structure of this application, the clamping body 110 can clamp the steering column 10 or loosen the steering column 10 by extending and retracting the telescopic component 200. Therefore, there is no need to set threads on the connecting rod 120, that is, the threaded structure is eliminated, which can avoid the phenomenon of stripping, improve the stability of the clamping body 110, reduce the probability of the clamping body 110 loosening, and improve the stability of the steering column holding force structure.

[0063] In other embodiments, refer to Figure 7 , Figure 8 and Figure 9As shown, the telescopic assembly 200 includes a first disc 210 and a second disc 220. Both the first disc 210 and the second disc 220 are mounted on the connecting rod 120. The side of the first disc 210 facing the second disc 220 has at least one groove 300. The groove 300 includes a first section 310 and a second section 320. The groove depth of the first section 310 is less than the groove depth of the second section 320. The second disc 220 has at least one slider 400 facing the first disc 210. Each slider 400 is slidably connected to the groove 300 in a one-to-one correspondence. The slider 400 is configured such that when it is in the first section 310, it increases the distance between the second disc 220 and the first disc 210, thereby extending the telescopic assembly 200; and when it is in the second section 320, it decreases the distance between the second disc 220 and the first disc 210, thereby shortening the telescopic assembly 200.

[0064] In this embodiment, since the groove depth of the first segment 310 is less than the groove depth of the second segment 320, the distance between the second disc 220 and the first disc 210 when the slider 400 is in the first segment 310 is greater than the distance between the second disc 220 and the first disc 210 when the slider 400 is in the second segment. That is, when the slider 400 is in the first segment 310, the telescopic component 200 is extended; when it is in the second segment 320, the telescopic component 200 is shortened.

[0065] In practical use, the user only needs to move the second disc 220 so that the slider 400 of the second disc 220 moves on the groove 300 of the first disc 210, so that the clamp 110 can clamp the steering column 10 or the clamp 110 can release the steering column 10.

[0066] Furthermore, a smooth arc-shaped transition surface is formed at the junction of the first segment 310 and the second segment 320, so that the slider 400 can slide smoothly between the first segment 310 and the second segment 320.

[0067] In other possible embodiments, refer to Figure 7 , Figure 8 and Figure 9 As shown, a first slide rail 510 is provided on the first segment 310 along the extension direction of the first segment 310, and a second slide rail 520 is provided on the second segment 320 along the extension direction of the second segment 320. The first slide rail 510 and the second slide rail 520 are connected to form a continuous guide rail 500. A ball bearing 600 is rolled on the side of the slider 400 facing the slide groove 300, and the ball bearing 600 is rolledly connected to the guide rail 500.

[0068] In this embodiment, the extension direction of the first slide rail 510 is the same as the extension direction of the first segment 310, and the extension direction of the second slide rail 520 is the same as the extension direction of the second segment 320. The slider 400 is rolled on the guide rail 500 on the slide groove 300 by the ball bearing 600, thereby reducing the friction of the slider 400 and making the slider 400 move more smoothly on the slide groove 300. This reduces the operating force required for the user to rotate the second disc 220, and the magnitude of the operating force is relatively stable, thus improving the user experience.

[0069] Furthermore, by using the rolling connection between the ball bearing 600 and the guide rail 500, there is no need to apply grease or other lubricants between the first disc 210 and the second disc 220, which also reduces the number of parts between the first disc 210 and the second disc 220.

[0070] In some embodiments, reference is made to Figure 8 and Figure 9 As shown, each of the slide grooves 300 is arranged in a ring array along the circumference of the first disk body 210.

[0071] In this embodiment, each slide groove 300 is arranged in a ring array along the circumference of the first disc 210, and each corresponding slider 400 is arranged in a ring array along the circumference of the second disc 220, thereby making the first disc 210 and the second disc 220 uniformly stressed and ensuring that the hoop 110 can be stressed stably.

[0072] In another possible embodiment, refer to Figure 8 and Figure 9 As shown, the first disc body 210 has a first mounting through hole 211 at its center, and the second disc body 220 has a second mounting through hole 221 at its center. The first disc body 210 is sleeved on the connecting rod 120 through the first mounting through hole 211, and the second disc body 220 is sleeved on the connecting rod 120 through the second mounting through hole 221.

[0073] In this embodiment, during use, the user rotates the second disc 220, and the slider 400 on the second disc 220 will move on the groove 300 of the first disc 210, which can realize the clamp 110 clamping the steering column 10 or the clamp 110 releasing the steering column 10. Since the first disc 210 is sleeved on the connecting rod 120 through the first mounting through hole 211, and the second disc 220 is sleeved on the connecting rod 120 through the second mounting through hole 221, the first disc 210 and the second disc 220 are subjected to uniform force, so that the telescopic component 200 can extend and retract stably, thereby ensuring that the clamp 110 can be subjected to stable force.

[0074] In some embodiments, reference is made to Figure 1 and Figure 2As shown, it also includes a handle 700, which is disposed on the second disc body 220. The handle 700 is used to drive the second disc body 220 to rotate on the connecting rod 120 so that the slider 400 slides on the slide groove 300.

[0075] In this embodiment, the user can rotate the second disc 220 by turning the handle 700, thereby enabling the clamp 110 to clamp the steering column 10 or the clamp 110 to release the steering column 10, which improves the user's convenience.

[0076] In other embodiments, refer to Figure 10 As shown, the guide rail 500 is provided with a first elastic limiting member 900 and a second elastic limiting member 1000 at both ends. Both the first elastic limiting member 900 and the second elastic limiting member 1000 are used to limit the ball 600.

[0077] In this embodiment, when the ball 600 rolls to both ends of the guide rail 500, the first elastic limiting member 900 or the second elastic limiting member 1000 can limit the ball 600 to prevent the ball 600 from continuing to roll along the guide rail 500 without the user turning the handle 700 or the second disc 220.

[0078] In other words, when the user does not turn the handle 700 or the second disc 220, the first elastic limiter 900 or the second elastic limiter 1000 can keep the ball 600 fixed, thereby keeping the clamp 110 clamping the steering column 10 or the clamp 110 releasing the steering column 10.

[0079] Specifically, both the first elastic limiting member 900 and the second elastic limiting member 1000 are spring members, and the two spring members are respectively set on the bottom of both ends of the guide rail 500.

[0080] When the ball 600 rolls to the end of the guide rail 500, the spring is compressed, which clamps the ball 600 between the spring and the slider 400, thereby limiting the movement of the ball 600.

[0081] In some possible embodiments, refer to Figure 6 As shown, the first limiting member 130 is the first nut, and the second limiting member 140 is the second nut.

[0082] In this embodiment, the first limiting member 130 is a first nut and the second limiting member 140 is a second nut. The first nut can be threadedly connected to the connecting rod 120, and the second nut can be integrally formed with the connecting rod 120. Thus, when disassembly or installation is required, only the first nut needs to be turned.

[0083] In other possible embodiments, refer to Figure 1 and Figure 2 As shown, it also includes a mounting bracket 800, on which a first bracket 810 and a second bracket 820 are provided. Both the first bracket 810 and the second bracket 820 are passed through the connecting rod 120. The first bracket 810 is located between the first limiting member 130 and the first connecting end 111, and the second bracket 820 is located between the second limiting member 140 and the telescopic assembly 200. The mounting bracket 800 is used to connect with the vehicle body.

[0084] In this embodiment, the first bracket 810 and the second bracket 820 of the mounting bracket 800 also form a clamping structure. The clamping structure formed by the first bracket 810 and the second bracket 820 clamps the clamp body 110. That is, when the telescopic component 200 extends or retracts, by changing the distance between the first bracket 810 and the second bracket 820, the distance between the first connecting end 111 and the second connecting end 112 of the clamp body 110 is changed, thereby realizing that the clamp body 110 clamps the steering column 10 or the clamp body 110 releases the steering column 10.

[0085] It should be noted that the hoop 110 is connected to the vehicle body via the mounting bracket 800.

[0086] A second aspect of this application provides a vehicle, including a vehicle body and a steering column retaining force structure of any of the above embodiments.

[0087] The steering column retaining force structure is located on the vehicle body.

[0088] In use, the hoop 110 is installed on the vehicle body and is fitted onto the steering column 10.

[0089] The vehicle body of this application embodiment is provided with a steering column holding force structure according to this application embodiment. The steering column holding force structure includes a clamp assembly 100 and a telescopic assembly 200. The clamp assembly 100 includes a clamp body 110, a connecting rod 120, a first limiting member 130, and a second limiting member 140. The clamp body 110 is used to fit onto the steering column 10 of the vehicle. One end of the connecting rod 120 passes through the first connecting end 111 of the clamp body 110 and connects to the first limiting member 130. The first limiting member 130 is used to limit the first connecting end 111 to the connecting rod 120. The other end of the connecting rod 120 passes through the second connecting end 112 of the clamp body 110 and connects to the second limiting member 140. The component 140 is used to limit the second connecting end 112 on the connecting rod 120; the telescopic component 200 is disposed on the connecting rod 120 and located between the second connecting end 112 and the second limiting component 140. The telescopic component 200 is configured such that, when extended, both ends of the telescopic component 200 abut against the second limiting component 140 and the second connecting end 112 respectively, so as to push the second connecting end 112 closer to the first connecting end 111, so as to make the clamp 110 clamp the steering column 10; when shortened, both ends of the telescopic component 200 disengage from the second limiting component 140 and the second connecting end 112 respectively, so as to make the second connecting end 112 move away from the first connecting end 111, so as to make the clamp 110 release the steering column 10.

[0090] In the vehicle of this application, when the telescopic component 200 extends, both ends of the telescopic component 200 abut against the second limiting member 140 and the second connecting end 112, respectively. The telescopic component 200 can push the second connecting end 112 closer to the first connecting end 111, causing the second connecting end 112 of the clamp 110 to move closer to the first connecting end 111. At this time, the clamping force of the clamp 110 on the steering column 10 increases, thereby allowing the clamp 110 to clamp the steering column 10. When the telescopic component 200 shortens, both ends of the telescopic component 200 disengage from the second limiting member 140 and the second connecting end 112, respectively, causing the second connecting end 112 to move away from the first connecting end 111. At this time, the clamping force of the clamp 110 on the steering column 10 decreases, thereby allowing the clamp 110 to release the steering column 10. In the steering column holding force structure of this application, the clamping body 110 can clamp the steering column 10 or loosen the steering column 10 by extending and retracting the telescopic component 200. Therefore, there is no need to set threads on the connecting rod 120, that is, the threaded structure is eliminated, which can avoid the phenomenon of stripping, improve the stability of the clamping body 110, reduce the probability of the clamping body 110 loosening, and improve the stability of the steering column holding force structure.
