Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a steering column clamping mechanism assembly and a vehicle. BACKGROUND

[0002] At present, the collision protection mode of the steering column is designed with a collapse energy absorption mechanism. When the vehicle collides frontally, the impact force can be transmitted to the collapse energy absorption mechanism, and the collapse energy absorption mechanism can form a buffer protection for the driver by absorbing the impact energy.

[0003] Since the steering column is generally an angle-adjustable structure, when an impact occurs, the steering wheel angle changes first, thereby affecting the transmission angle of the impact force and reducing the effect of the collapse energy absorption mechanism on absorbing the impact force. At the same time, due to the change of the steering wheel angle, the steering wheel with the airbag moves upward, and the airbag cannot face the driver after being blown open, which also reduces the protection effect of the airbag. CONTENT OF THE INVENTION

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present application provides a steering column clamping mechanism assembly and a vehicle.

[0005] The first aspect of the present application provides a steering column clamping mechanism assembly, comprising:

[0006] A mounting bracket is provided with a mounting space for accommodating a steering column;

[0007] A first elastic sheet is arranged on one side of the steering column and elastically abuts against the steering column;

[0008] A second elastic sheet is arranged on the other side of the steering column and elastically abuts against the steering column, and the second elastic sheet is arranged opposite to the first elastic sheet;

[0009] A locking assembly is arranged in the mounting bracket and is configured to press the second elastic sheet and the first elastic sheet on both sides of the steering column in a locked state, so that the second elastic sheet and the first elastic sheet limit the deflection of the steering column.

[0010] The steering column clamping mechanism assembly provided in the application has a mounting space for accommodating the steering column formed on the mounting bracket, the first elastic sheet and the second elastic sheet are oppositely arranged and respectively located at opposite sides of the steering column when the steering column is located in the mounting space, the locking assembly can press the second elastic sheet and the first elastic sheet on both sides of the steering column, so that the steering column is pressed and limited between the first elastic sheet and the second elastic sheet under the action of the elastic abutting force, the first elastic sheet and the second elastic sheet can be elastically deformed under the action of the locking assembly, so as to increase the contact area between the first elastic sheet and the steering column and between the second elastic sheet and the steering column, and further increase the friction force between the first elastic sheet and the steering column and between the second elastic sheet and the steering column, thereby playing a role of angle limiting of the steering column, and ensuring that the steering column does not deflect when a collision occurs, so that the column collapse structure and the airbag can fully protect the driver and improve the safety performance.

[0011] In some embodiments, the locking assembly comprises a clamping shaft, a first abutting block and a second abutting block;

[0012] The clamping shaft is sequentially arranged through the first elastic sheet, the steering column and the second elastic sheet, the first abutting block and the second abutting block are both sleeved on the clamping shaft, the first abutting block is located outside the first elastic sheet, and the second abutting block is located outside the second elastic sheet;

[0013] When the locking assembly is in a locking state, the first abutting block is driven to be close to the second abutting block to press the second elastic sheet and the first elastic sheet on both sides of the steering column.

[0014] Based on the above-mentioned embodiments, the clamping shaft sequentially passes through the first abutting block, the first elastic sheet, the steering column, the second elastic sheet and the second abutting block to limit the first elastic sheet, the steering column and the second elastic sheet on the clamping shaft, which can not only realize the radial limitation of the first elastic sheet, the steering column and the second elastic sheet on the clamping shaft, but also realize the axial limitation of the first elastic sheet, the steering column and the second elastic sheet on the clamping shaft.

[0015] In some embodiments, the locking assembly further comprises a first cam and a second cam, and the first cam and the second cam are both sleeved on the clamping shaft;

[0016] The second cam is fixedly connected with the second abutting block, and the first cam rotates relative to the second cam to drive the first cam to move away from the second cam along the axial direction of the clamping shaft, so as to drive the first abutting block to be close to the second abutting block.

[0017] Based on the above embodiment, the first cam can be away from the second cam, at this time, the axial length occupied by the first cam and the second cam on the clamping shaft relatively increases. In this way, the axial length occupied by the first abutting block, the second abutting block and the steering column located between the first abutting block and the second abutting block is adaptively compressed, and the steering column can be further compressed and limited between the first elastic sheet and the second elastic sheet by compressing the first elastic sheet and the second elastic sheet.

[0018] In some embodiments, the first cam is located on the side of the second cam away from the second elastic sheet;

[0019] The first cam comprises a first protruding part and a first recessed part, and the second cam comprises a second protruding part and a second recessed part;

[0020] The first protruding part can abut against the second protruding part to make the first cam away from the second cam to drive the first abutting block to approach the second abutting block and lock the locking assembly;

[0021] The first protruding part can also engage with the second recessed part, or the second protruding part engages with the first recessed part, to make the first cam approach the second cam to unlock the locking assembly and drive the first abutting block away from the second abutting block.

[0022] Based on the above embodiment, when the first protruding part abuts against the second protruding part, the first cam can be away from the second cam to drive the first abutting block to approach the second abutting block and lock the locking assembly to compress the steering column and achieve limiting. The first protruding part can also disengage from the second protruding part to make the first protruding part engage with the second recessed part or make the second protruding part engage with the first recessed part, and the first cam can approach the second cam to unlock the locking assembly, and then the first abutting block moves away from the second abutting block to release the first elastic sheet and the second elastic sheet.

[0023] In some embodiments, the locking assembly further comprises a handle, and the handle is fixedly connected with the first cam.

[0024] Based on the above embodiment, the handle can be pulled to drive the first cam to rotate, which facilitates the loosening or compression of the steering column and is convenient and labor-saving.

[0025] In some embodiments, the clamping shaft is provided with a first limiting piece and a second limiting piece at two ends respectively, the first limiting piece is located on the side of the first abutting block away from the first elastic sheet, and the second limiting piece is located on the side of the second abutting block away from the second elastic sheet.

[0026] Based on the above embodiment, the first limiting piece and the second limiting piece can form an axial mounting space with a fixed length on the clamping shaft, and then the axial length occupied by the first abutting block, the second abutting block and the steering column between the first abutting block and the second abutting block can be adaptively changed when the first cam is close to or away from the second cam, and then the loosening or compression of the steering column can be realized.

[0027] In some embodiments, a first through hole is arranged on the mounting bracket, and a plurality of first teeth are arranged on the inner walls of the opposite sides of the first through hole;

[0028] The first abutting block is fixedly sleeved on the clamping shaft, and a plurality of second teeth are arranged on the outer walls of the opposite sides of the first abutting block;

[0029] When the locking assembly is in the locked state, the first teeth and the second teeth are engaged, and the clamping shaft is relatively fixed with the steering column.

[0030] Based on the above embodiment, the relative rotation between the first abutting block and the first through hole can be limited by the mutual engagement of the first teeth and the second teeth, and the friction between the first elastic sheet, the steering column and the second elastic sheet and the steering column can further improve the limitation of deflection and reduce the possibility of deflection of the angle of the steering column relative to the mounting bracket when the first abutting block is fixedly sleeved on the clamping shaft.

[0031] In some embodiments, part of the clamping shaft is formed into a square shaft, a first square hole is arranged on the first abutting block and matched with the square shaft, and the square shaft is inserted into the first square hole;

[0032] And / or, a square fixing block is fixedly sleeved on the clamping shaft, a second square hole is arranged on the steering column and matched with the square fixing block, and the square fixing block is inserted into the second square hole.

[0033] Based on the above embodiment, the square shaft is inserted into the first square hole, so that the first abutting block can be fixedly sleeved on the clamping shaft to avoid relative rotation, and when the first teeth and the second teeth are engaged, the first abutting block can be fixed relative to the mounting bracket when the mounting bracket is fixed, thereby limiting the rotation of the clamping shaft; further, the square fixing block is inserted into the second square hole, so that the clamping shaft can be prevented from rotating relative to the steering column, and then the mutual engagement between the first teeth and the second teeth can fix the angle of the steering column relative to the mounting bracket, thereby ensuring the direction of force transmission during collision.

[0034] In some embodiments, the mounting bracket is provided with a first side bracket and a second side bracket in opposition and at intervals, and the mounting space is formed between the first side bracket and the second side bracket;

[0035] The first through hole is arranged on the first side bracket, and the second through hole is arranged on the second side bracket;

[0036] The clamping shaft is arranged in sequence through the first through hole, the first elastic sheet, the steering column, the second elastic sheet and the second through hole.

DETAILED DESCRIPTION

[0051] In order to enable the above object, features and advantages of the present application to be more clearly understood, a further description will be made to the scheme of the present application. It should be explained that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0052] In the following description, a lot of specific details are set forth in order to fully understand the present application, but the present application can also be implemented in other ways different from the description; obviously, the embodiments in the specification are only some of the embodiments of the present application, not all the embodiments.

[0053] The steering column clamping mechanism assembly and the vehicle will be described in detail through specific embodiments as follows:

[0054] Referring to Figures 1 to 8 The utility model provides a kind of steering column clamping mechanism assembly, including mounting bracket 1, first elastic sheet 2, second elastic sheet 3 and locking assembly 4, as shown in the figure.

[0055] When the steering column 5 is located in the mounting space, the first elastic sheet 2 and the second elastic sheet 3 are oppositely arranged and located at opposite sides of the steering column 5 respectively, and the locking assembly 4 can press the first elastic sheet 2 and the second elastic sheet 3 against the two sides of the steering column 5, so that the steering column 5 is pressed and positioned between the first elastic sheet 2 and the second elastic sheet 3 under the elastic abutting force.

[0056] The first elastic sheet 2 is arranged at one side of the steering column 5 and elastically abuts against the steering column 5, the second elastic sheet 3 is arranged at the other side of the steering column 5 and elastically abuts against the steering column 5, the second elastic sheet 3 is oppositely arranged with the first elastic sheet 2, and the locking assembly 4 is arranged in the mounting bracket 1 and configured to press the second elastic sheet 3 and the first elastic sheet 2 against the two sides of the steering column 5 in the locked state, so that the second elastic sheet 3 and the first elastic sheet 2 limit the deflection of the steering column 5.

[0057] It can be understood that, under the action of the locking assembly 4, the first elastic sheet 2 and the second elastic sheet 3 can be elastically deformed to increase the contact area between the first elastic sheet 2 and the steering column 5 and between the second elastic sheet 3 and the steering column 5, thereby increasing the friction between the first elastic sheet 2 and the steering column 5 and between the second elastic sheet 3 and the steering column 5, playing a role in limiting the angle of the steering column 5, and ensuring that the steering column 5 does not deflect when a collision occurs, so that the column collapse structure and the airbag can fully protect the driver and improve the safety performance.

[0058] Specifically, the first elastic sheet 2 and the second elastic sheet 3 can be spring steel sheets or 65 manganese sheets, and the first elastic sheet 2 and the second elastic sheet 3 both have sufficient structural strength, which can not only apply an axial limiting force to the steering column 5 when the first elastic sheet 2 and the second elastic sheet 3 abut against the two sides of the steering column 5 respectively to ensure the axial limiting effect, but also can prevent the angle of the steering column 5 from deflecting through the friction between the first elastic sheet 2 and the steering column 5 and between the second elastic sheet 3 and the steering column 5.

[0059] In some embodiments, referring to Figure 1 , Figure 3 and Figure 5 , the locking assembly 4 includes a clamping shaft 41, a first abutting block 42 and a second abutting block 43, the clamping shaft 41 is sequentially arranged through the first elastic sheet 2, the steering column 5 and the second elastic sheet 3, the first abutting block 42 and the second abutting block 43 are both sleeved on the clamping shaft 41, and the first abutting block 42 is located outside the first elastic sheet 2 and the second abutting block 43 is located outside the second elastic sheet 3. That is, the clamping shaft 41 sequentially passes through the first abutting block 42, the first elastic sheet 2, the steering column 5, the second elastic sheet 3 and the second abutting block 43, so as to limit the first elastic sheet 2, the steering column 5 and the second elastic sheet 3 on the clamping shaft 41.

[0060] When the locking assembly 4 is in the locked state, the first abutting block 42 is driven to be close to the second abutting block 43, so as to press the second spring plate 3 and the first spring plate 2 on both sides of the steering column 5, so that the second spring plate 3 and the first spring plate 2 limit the deflection of the steering column 5.

[0061] It can be understood that the clamping shaft 41 passes through the first spring plate 2, the steering column 5 and the second spring plate 3 in sequence, which can realize the radial limiting of the first spring plate 2, the steering column 5 and the second spring plate 3 on the clamping shaft 41, and at the same time, when the second spring plate 3 and the first spring plate 2 are pressed on both sides of the steering column 5, the axial limiting of the first spring plate 2, the steering column 5 and the second spring plate 3 on the clamping shaft 41 can also be realized.

[0062] In some embodiments, the locking assembly 4 further comprises a first cam 44 and a second cam 45, the first cam 44 and the second cam 45 are sleeved on the clamping shaft 41, the second cam 45 is fixedly connected with the second abutting block 43, and the first cam 44 rotates relative to the second cam 45 to drive the first cam 44 to move away from the second cam 45 along the axial direction of the clamping shaft 41, so as to drive the first abutting block 42 to be close to the second abutting block 43.

[0063] It can be understood that the first cam 44 can move away from the second cam 45, at this time, the axial length occupied by the first cam 44 and the second cam 45 on the clamping shaft 41 relatively increases. In this way, the axial length occupied by the first abutting block 42, the second abutting block 43 and the steering column 5 located between the first abutting block 42 and the second abutting block 43 is adaptively compressed, so as to be able to press the first spring plate 2 and the second spring plate 3 to press and limit the steering column 5 between them.

[0064] Specifically, referring to Figure 4 , Figure 6 and Figure 7 , the first cam 44 is located on the side of the second cam 45 away from the second spring plate 3, the first cam 44 comprises a first protruding part 441 and a first recess part 442, the second cam 45 comprises a second protruding part 451 and a second recess part 452, the first protruding part 441 can abut against the second protruding part 451, so that the first cam 44 moves away from the second cam 45, so as to drive the first abutting block 42 to be close to the second abutting block 43 and lock the above-mentioned locking assembly 4, so as to press the steering column 5 and realize the limiting.

[0065] That is to say, on the clamping shaft 41, the first cam 44, the second cam 45, the second abutting block 43, the second elastic sheet 3, the steering column 5, the first elastic sheet 2 and the first abutting block 42 are sequentially arranged, when the first cam 44 is away from the second cam 45, the first abutting block 42 can be driven to be close to the second abutting block 43, and then the first abutting block 42 can be pressed on the first elastic sheet 2, and the second abutting block 43 can be pressed on the second elastic sheet 3, in this way, the first elastic sheet 2 and the second elastic sheet 3 can be pressed to limit the steering column 5 between them, so as to avoid the angle of the steering column 5 from being deflected.

[0066] Further, the first protruding part 441 can also be engaged with the second recessed part 452, or the second protruding part 451 is engaged with the first recessed part 442, so that the first cam 44 is close to the second cam 45, to unlock the locking assembly 4 and drive the first abutting block 42 to be away from the second abutting block 43. That is to say, the first protruding part 441 can be disengaged from the second protruding part 451, so that the first protruding part 441 can be engaged with the second recessed part 452, or the second protruding part 451 is engaged with the first recessed part 442.

[0067] In this way, the first cam 44 can be close to the second cam 45 to release the axial length occupied by the first abutting block 42, the second abutting block 43 and the steering column 5 between the first abutting block 42 and the second abutting block 43, so as to release the locking state of the locking assembly 4, and then the first abutting block 42 is away from the second abutting block 43 to release the first elastic sheet 2 and the second elastic sheet 3.

[0068] In specific implementation, the number of the first protruding part 441 and the first recessed part 442 is the same and both are multiple, the multiple first protruding parts 441 and the multiple first recessed parts 442 are alternately arranged along the circumferential direction, the number of the second protruding part 451 and the second recessed part 452 is the same and both are multiple, the multiple second protruding parts 451 and the multiple second recessed parts 452 are alternately arranged along the circumferential direction, when the first cam 44 or the second cam 45 is driven to rotate, the first protruding part 441 can be engaged with the second recessed part 452 or abutted with each other, so as to release or press the steering column 5.

[0069] Wherein, the number of the first protruding part 441 and the second protruding part 451 is the same, the number of the first recessed part 442 and the second recessed part 452 is the same, the first protruding part 441 and the second protruding part 451, and the first recessed part 442 and the second recessed part 452 can be arranged one by one; the first protruding part 441 and the second recessed part 452, and the second protruding part 451 and the first recessed part 442 can be engaged one by one.

[0070] Reference Figure 5As shown, the locking assembly 4 further comprises a handle 46 fixedly connected with the first cam 44. That is, the handle 46 can drive the first cam 44 to rotate by pulling, facilitating the loosening or compression of the steering column 5.

[0071] In some embodiments, with reference to Figure 1 and Figure 3 As shown, the clamping shaft 41 is provided with a first limiting piece 411 and a second limiting piece 412 at two ends respectively, the first limiting piece 411 is located at the side of the first abutting block 42 away from the first spring 2, and the second limiting piece 412 is located at the side of the second abutting block 43 away from the second spring 3.

[0072] It can be understood that an axial installation space with a fixed length is formed between the first limiting piece 411 and the second limiting piece 412. In this way, when the first cam 44 is close to the second cam 45, the axial length occupied by the first cam 44 and the second cam 45 on the clamping shaft 41 is relatively reduced, and the axial length occupied by the first abutting block 42, the second abutting block 43 and the steering column 5 located between the first abutting block 42 and the second abutting block 43 is adaptively released; when the first cam 44 is away from the second cam 45, the axial length occupied by the first cam 44 and the second cam 45 on the clamping shaft 41 is relatively increased, and the axial length occupied by the first abutting block 42, the second abutting block 43 and the steering column 5 located between the first abutting block 42 and the second abutting block 43 is adaptively compressed.

[0073] Specifically, the first limiting piece 411 can be a limiting plate integrally formed at the end of the clamping shaft 41, the limiting plate is abutted at the side of the first abutting block 42 away from the second abutting block 43 to achieve limiting, and the first limiting piece 411 is fixedly sleeved on the clamping shaft 41.

[0074] The second limiting piece 412 can be a locking nut, after the clamping shaft 41 sequentially passes through the first spring 2, the steering column 5, the second spring 3, the second cam 45 and the first cam 44, the locking nut is tightened on the clamping shaft 41, and the assembly of the steering column clamping mechanism assembly can be completed. It can be understood that the second limiting piece 412 is movably sleeved on the clamping shaft 41, and by screwing the locking nut, the length of the axial installation space between the first limiting piece 411 and the second limiting piece 412 can be changed.

[0075] Further, at least one of the first cam 44 and the second cam 45 can move axially relative to the clamping shaft 41, thereby being able to realize the first cam 44 close to or away from the second cam 45, and being able to realize the loosening or compression of the first spring 2 and the second spring 3.

[0076] In some embodiments, the mounting bracket 1 is provided with a first through hole 111, a plurality of first teeth 112 are arranged on the inner walls of opposite sides of the first through hole 111, the first abutting block 42 is fixedly sleeved on the clamping shaft 41, a plurality of second teeth 421 are arranged on the outer walls of opposite sides of the first abutting block 42, and the first teeth 112 and the second teeth 421 are engaged in the locked state of the locking assembly 4.

[0077] That is, by the mutual engagement of the first teeth 112 and the second teeth 421, the relative rotation between the first abutting block 42 and the first through hole 111 (i.e., the mounting bracket 1) can be limited, and since the clamping shaft 41 is relatively fixed with the steering column 5, when the first abutting block 42 is fixedly sleeved on the clamping shaft 41, the friction between the first elastic sheet 2 and the steering column 5 and the friction between the second elastic sheet 3 and the steering column 5 can be further improved to limit the deflection and reduce the possibility of the deflection of the steering column 5 relative to the mounting bracket 1.

[0078] Specifically, the part of the clamping shaft 41 matched with the first abutting block 42 is formed into a square shaft, a first square hole is formed on the first abutting block 42 and matched with the square shaft, and the square shaft is inserted into the first square hole, so that the first abutting block 42 can be fixedly sleeved on the clamping shaft 41 to avoid relative rotation, and when the first teeth 112 and the second teeth 421 are engaged, the first abutting block 42 can be fixed relative to the mounting bracket 1 when the mounting bracket 1 is fixed, thereby limiting the rotation of the clamping shaft 41, and thus when the clamping shaft 41 is fixedly assembled with the steering column 5, the deflection of the steering column 5 can be limited.

[0079] Further, the square fixing block 413 is fixedly sleeved on the clamping shaft 41, a second square hole is formed on the steering column 5 and matched with the square fixing block 413, and the square fixing block 413 is inserted into the second square hole, so that the rotation of the clamping shaft 41 relative to the steering column 5 can be avoided, and the mutual engagement between the first teeth 112 and the second teeth 421 can make the steering column 5 fixed relative to the mounting bracket 1 in terms of angle, thereby ensuring the transmission direction of the force in the collision.

[0080] Specifically, two square fixing blocks 413 are arranged on the clamping shaft 41, and two second square holes are formed on the two sides of the steering column 5 and matched with the two square fixing blocks 413.

[0081] In some embodiments, as shown in Figure 5 , the mounting bracket 1 is provided with a second through hole 121, a first via hole 21 is formed on the first elastic sheet 2 and faces the first through hole 111, and a second via hole 31 is formed on the second elastic sheet 3 and faces the second through hole 121.

[0082] Specifically, the size of the first via hole 21 is smaller than the size of the first through hole 111, and the size of the second via hole 31 is smaller than the size of the second through hole 121, that is, at least part of the first elastic sheet 2 is exposed through the first through hole 111, so that the first abutting block 42 can abut on the first elastic sheet 2 exposed through the first through hole 111; at the same time, at least part of the second elastic sheet 3 is exposed through the second through hole 121, so that the second abutting block 43 can abut on the second elastic sheet 3 exposed through the second through hole 121.

[0083] The clamping shaft 41 is arranged through the first through hole 111, the first via hole 21, the steering column 5, the second via hole 31 and the second through hole 121 in sequence, so as to realize the limiting and fixing between the clamping shaft 41, the first elastic sheet 2, the steering column 5 and the second elastic sheet 3. Specifically, not only the radial limiting of the first elastic sheet 2, the steering column 5 and the second elastic sheet 3 on the clamping shaft 41 can be realized, but also the axial limiting of the first elastic sheet 2, the steering column 5 and the second elastic sheet 3 on the clamping shaft 41 can be realized, and then the loosening or compression of the steering column 5 can be realized through the first abutting block 42 and the second abutting block 43.
