[0033] The embodiments of this application will be described below in conjunction with the accompanying drawings of the specification. It can be understood that the technical features involved in the different embodiments described below can be combined with each other as long as they do not conflict with each other.

[0034] Refer to Figure 1 , an embodiment of this application proposes a vehicle braking mechanism, which includes a brake hose 10 and a guiding assembly 20. Among them, the brake hose 10 is used to provide a braking medium for a braking component 30. The guiding assembly 20 is provided with at least one group and includes a limiting channel, and at least a part of the structure of the brake hose 10 is disposed in the limiting channel.

[0035] In this embodiment, by providing the guiding assembly 20 to guide the brake hose 10, the movement of the brake hose 10 is effectively restricted, avoiding unnecessary interference with other vehicle components, reducing the wear risk and potential safety hazards, and ensuring that the braking medium can be smoothly transmitted to the braking component 30.

[0036] In some embodiments, referring to Figure 1 , the guiding assembly 20 includes a plurality of guiding rings 202. The plurality of guiding rings 202 are arranged at intervals and enclose a limiting channel, and the brake hose 10 sequentially passes through the plurality of guiding rings 202.

[0037] In this embodiment, the brake hose 10 sequentially passes through the plurality of guiding rings 202. Each guiding ring 202 limits the brake hose 10 at specific points, and the plurality of guiding rings 202 cooperate to form a structure similar to a limiting channel. Obviously, the more the number of guiding rings 202, the better the limiting effect on the brake hose 10. The design of the guiding ring 202 allows the brake hose 10 to still maintain its predetermined path when subjected to external forces, preventing damage or failure caused by irregular movement, and improving the reliability and safety of the system.

[0038] In some embodiments, referring to Figure 1 , the guiding assembly 20 includes a driving member 201. The driving member 201 is drivingly connected to the plurality of guiding rings 202, and the driving member 201 is used to drive the plurality of guiding rings 202 to move closer to or away from each other.

[0039] This embodiment ensures that the brake hose 10 can automatically adjust its orientation according to the actual driving state of the vehicle through the driving member 201 to adapt to different road conditions and driving conditions, thereby further reducing wear and improving driving safety. It should be understood that when the driving member 201 drives the plurality of guiding rings 202 to move closer to each other, the guiding effect of the guiding rings 202 on the brake hose 10 is smaller or has no guiding effect; when the driving member 201 drives the plurality of guiding rings 202 to move away from each other, the guiding rings 202 restrict the orientation of the brake hose 10 and play a guiding effect.

[0040] Specifically, the guiding ring 202 and the brake hose 10 are in clearance fit, and the maximum clearance between the two is a, and 0mm < a ≤ 5mm is satisfied. It should be noted that if a is too small, it is difficult for the guiding ring 202 to move relative to the brake hose 10; if a is too large, the constraining effect of the guiding ring 202 on the brake hose 10 is poor, and the guiding effect cannot be well achieved.

[0041] Optionally, the driving member 201 can be but is not limited to a multi-stage telescopic hydraulic cylinder or a multi-stage telescopic electric cylinder. Referring to Figure 1, the driving member 201 has a telescopically arranged power output portion 2011. Further, the power output portion 2011 includes a cylinder 2013 arranged with multiple levels of nesting, and multiple guide rings 202 are respectively connected to the multi-level cylinder 2013 through connectors 203. Optionally, referring to Figure 1 , the connector 203 is connected to one end of the cylinder 2013 away from the driving member body 2012, so that each cylinder 2013 can be fully retracted.

[0042] Optionally, referring to Figure 2 , a first connector 2031 is connected to the cylinder 2013 at the outermost level farthest from the driving member body 2012. The first connector 2031 is provided with two spaced-apart branch portions 2032, and each branch portion 2032 is connected to a guide ring 202. When the number of cylinders 2013 is limited, the first connector 2031 extends an additional distance and is connected to the guide ring 202 to enhance the guiding effect. Moreover, when the cylinder 2013 is fully retracted, this structure can also play a partial guiding effect.

[0043] In some embodiments, referring to Figure 1 and Figure 2 , the guiding assembly 20 includes a first assembly 210 and a second assembly 220. The driving member 201 of the first assembly 210 is used to drive multiple guide rings 202 to approach or move away from each other along the first direction X, and the driving member 201 of the second assembly 220 is used to drive multiple guide rings 202 to approach or move away from each other along the second direction Y. There is a preset angle between the first direction X and the second direction Y.

[0044] This embodiment allows the brake hose 10 to be precisely controlled in multiple dimensions. Especially in complex or variable driving road conditions, it provides a more flexible response ability for guiding the brake hose 10.

[0045] It should be noted that in some vehicles, when the brake hose 10 is long enough, the guiding assembly 20 does not need to be telescopically arranged (that is, the driving member 201 does not need to be set), that is, multiple guide rings 202 always remain in a state of moving away from each other, so as to play a role in restricting the routing of the brake hose 10 and guiding. In some vehicles, when the brake hose 10 is short, the guiding assembly 20 needs to be telescopically arranged; that is, when the steering knuckle 50 drives the tube body to move, it is easy to stretch and straighten the tube body. In this case, the driving member 201 of the guiding assembly 20 needs to drive multiple guide rings 202 to approach each other, that is, no guiding effect is generated, so as to avoid the misalignment between the guiding path and the straightening direction, and damage the brake hose 10 or the guiding assembly 20.

[0046] In some embodiments, referring to Figure 3, the vehicle braking mechanism further includes a brake component 30, a vehicle body component 40, and a steering knuckle 50. The steering knuckle 50 is used to connect to a wheel. The brake component 30 is connected to the steering knuckle 50. The brake component 30 is provided with a first fixing structure 301, the steering knuckle 50 is provided with a second fixing structure 501, and the vehicle body component 40 is provided with a third fixing structure 401. The brake hose 10 is sequentially passed through and fixed to the first fixing structure 301, the second fixing structure 501, and the third fixing structure 401. The first assembly 210 is arranged at the vehicle body component 40, and the second assembly 220 is arranged at the steering knuckle 50.

[0047] In this embodiment, by closely integrating each part and using the guiding assembly 20 to manage the position of the brake hose 10, the stability and coordination of the overall structure are enhanced.

[0048] Specifically, referring to Figure 3 , the brake component 30 includes a brake caliper 310 and a brake disc 320. The brake disc 320 shares an axle with the wheel. The brake hose 10 provides a braking medium for the brake caliper 310, so that the brake caliper 310 can clamp the brake disc 320, that is, prevent the brake disc 320 from rotating, thereby making the axle and the wheel both stop rotating, that is, realizing the braking of the wheel. In addition, the steering knuckle 50 is connected to the wheel, that is, the steering knuckle 50 can realize the synchronous inward and outward deflection and up and down displacement with the wheel (relative to the vehicle body component 40).

[0049] In some embodiments, the vehicle braking mechanism further includes a vehicle body component 40 and a steering knuckle 50. The first assembly 210 is arranged at the vehicle body component 40, and the second assembly 220 is arranged at the steering knuckle 50.

[0050] The driving members 201 of the first assembly 210 and the second assembly 220 both have a telescopic power output portion 2011. The guide ring 202 is connected to the power output portion 2011. The power output portion 2011 drives a plurality of guide rings 202 to approach or move away from each other. The relationship between the extension amount L1 of the power output portion 2011 of the first assembly 210 and the outward deflection angle θ of the wheel relative to the vehicle body component 40 conforms to the following formula:

[0051] When 0 ≤ θ ≤ π / 8, L1 = k1 × θ; when π / 8 < θ ≤ π / 4, L1 = k1 × (π / 4 - θ); where the value range of the coefficient k1 is 0 < k1 ≤ 1;

[0052] And / or, the relationship between the extension amount L2 of the power output portion 2011 of the second assembly 220 and the downward displacement amount h of the wheel relative to the vehicle body component 40 conforms to the following formula:

[0053] L2 = k1 × h, where the value range of the coefficient k1 is 0 < k1 ≤ 1.5.

[0054] In this embodiment, when the wheel deflects outward relative to the vehicle body component 40, the power output part 2011 of the driving part 201 of the first assembly 210 first gradually extends and then gradually retracts. Specifically, the maximum angle at which the wheel deflects outward relative to the vehicle body component 40 is generally 45°, that is, π / 4. At this time, the brake hose 10 is straightened, and the power output part 2011 needs to be fully retracted to avoid misalignment between the guiding path and the straightened extension direction, damaging the brake hose 10 or the guiding assembly 20; in the above formula, when the deflection angle ranges from 0 to π / 8, the power output part 2011 of the driving part 201 of the first assembly 210 gradually extends to drive the plurality of guiding rings 202 to move away from each other for guiding. When the deflection angle ranges from π / 8 to π / 4, the power output part 2011 of the driving part 201 of the first assembly 210 gradually retracts.

[0055] When the wheel moves downward relative to the vehicle body component 40, the power output part 2011 of the driving part 201 of the second assembly 220 gradually extends. Specifically, when the vehicle is briefly suspended, the wheel will move downward relative to the vehicle body component 40, and the downward movement amount is limited. Generally, the brake hose 10 will not be straightened. Therefore, the power output part 2011 of the driving part 201 of the second assembly 220 gradually extends with the downward movement amount of the wheel, thereby driving the plurality of guiding rings 202 to move away from each other to guide the brake hose 10.

[0056] In a second aspect, an embodiment of the present application provides a vehicle, which includes the vehicle braking mechanism of the first aspect.

[0057] Therefore, the vehicle of the second aspect includes all the technical effects of the vehicle braking mechanism of the first aspect, and the specific technical effects are not described herein again. In addition, it should be understood that the vehicle also includes other components, such as a power system, etc., and other components are not elaborated.

[0058] Optionally, the vehicle is a fuel vehicle, a new energy vehicle, a hybrid vehicle or a flying vehicle.

[0059] In a third aspect, an embodiment of the present application provides a control method for a vehicle braking mechanism, which is applied to the vehicle braking mechanism. The vehicle braking mechanism includes a brake hose 10 and a guiding assembly 20. The guiding assembly 20 includes a driving part 201 and a plurality of guiding rings 202. The brake hose 10 sequentially passes through the plurality of guiding rings 202, and the driving part 201 can drive the plurality of guiding rings 202 to move closer to or away from each other; the control method for the vehicle braking mechanism includes the following steps: obtaining the tension amount of the brake hose 10; when the tension amount reaches a first preset value, the driving part 201 drives the plurality of guiding rings 202 to move away from each other; when the tension amount reaches a second preset value, the driving part 201 drives the plurality of guiding rings 202 to move closer to each other; wherein, the second preset value is greater than the first preset value.

[0060] In this embodiment, the tension amount of the brake hose 10 can be obtained by monitoring the wheel deflection or up-and-down displacement through corresponding sensors. Specifically, the tension amount of the brake hose 10 can be understood as the increased amount of the straight-line distance between two preset points thereon. It can be understood that only when the bent brake hose 10 is gradually stretched, the straight-line distance between two preset points thereon will increase.

[0061] In practice, when the wheel deflects outward or moves downward relative to the vehicle body component 40, the brake hose 10 will be gradually stretched. At this time, some structures of the brake hose 10 (such as the part near the third fixing structure 401) will approach some components of the vehicle (such as the shock absorber), and interference is likely to occur. At this time, the brake hose 10 needs to be guided; on the contrary, when the wheel deflects inward or moves upward relative to the vehicle body component 40, the brake hose 10 will be sent back (or in other words, part of the brake hose 10 will be folded), and the brake hose 10 is not stretched, so there is no need to guide the brake hose 10.

[0062] In some embodiments, the guiding assembly 20 includes a first assembly 210. The first assembly 210 is arranged at the vehicle body component 40. The driving member 201 of the first assembly 210 can drive a plurality of guiding rings 202 to approach or move away from each other along the first direction X. The control method of the vehicle braking mechanism further includes: when the wheel deflects outward by a first angle relative to the vehicle body component 40, it is determined that the tension amount reaches a first preset value, and the driving member 201 of the first assembly 210 drives the plurality of guiding rings 202 to move away from each other; when the wheel deflects outward by a second angle relative to the vehicle body component 40, it is determined that the tension amount reaches a second preset value, and the driving member 201 of the first assembly 210 drives the plurality of guiding rings 202 to approach each other; where the second angle is greater than the first angle.

[0063] In this embodiment, when the vehicle is driving normally, the driving members 201 of the first assembly 210 and the second assembly 220 both drive the plurality of guiding rings 202 to be in a state of approaching each other, that is, the initial state (without guiding). When the wheel deflects outward by a first angle relative to the vehicle body component 40, the tension amount of the brake hose 10 is relatively small, and the driving member 201 of the first assembly 210 can drive the guiding rings 202 to move away from each other, that is, guide the brake hose 10. When the wheel deflects outward by a second angle relative to the vehicle body component 40, the tension amount of the brake hose 10 is relatively large (the brake hose 10 may be in a straightened state), and the driving member 201 of the first assembly 210 can drive the guiding rings 202 to approach each other, that is, do not guide the brake hose 10. Generally, in the above process, the second assembly 220 always maintains the initial state.

[0064] In some embodiments, the guiding assembly 20 includes a second assembly 220 disposed at the steering knuckle 50. A driving member 201 of the second assembly 220 can drive a plurality of guiding rings 202 to approach or move away from each other in the second direction Y. The control method of the vehicle braking mechanism further includes: when the wheel moves downward relative to the vehicle body component 40 by a first displacement amount, it is determined that the tension amount reaches a first preset value, and the driving member 201 of the second assembly 220 drives the plurality of guiding rings 202 to move away from each other.

[0065] In this embodiment, when the wheel moves downward relative to the vehicle body component 40 by the first displacement amount, the tension amount of the brake hose 10 is relatively small. The driving member 201 of the second assembly 220 drives the plurality of guiding rings 202 to move away from each other, that is, to guide the brake hose 10. Generally, in the above process, the first assembly 210 always remains in the initial state. It should be noted that the downward displacement of the wheels of most vehicles is limited and generally will not straighten the brake hose 10.

[0066] It should be understood that when the wheel is simultaneously deflected outward and moves downward, and the tension amount of the brake hose 10 does not reach the second preset value, both the first assembly 210 and the second assembly 220 drive the plurality of guiding rings 202 to move away from each other, that is, the first assembly 210 and the second assembly 220 simultaneously guide the brake hose 10. Further, when the wheel is simultaneously deflected outward and moves downward, and the tension amount of the brake hose 10 reaches the second preset value, both the first assembly 210 and the second assembly 220 drive the plurality of guiding rings 202 to approach each other.

[0067] Specifically, referring to Figure 4 , the present application uses an angle torsion sensor to monitor the deflection angle of the wheel relative to the vehicle body component 40 and transmits it to the controller. The controller controls the expansion and contraction of the power output portion 2011 of the driving member 201 of the first assembly 210 according to the situation of the wheel deflection angle. Similarly, the present application uses a height displacement sensor to monitor the vertical displacement amount of the wheel relative to the vehicle body component 40 and transmits it to the controller. The controller controls the expansion and contraction of the power output portion 2011 of the driving member 201 of the second assembly 220 according to the situation of the wheel vertical displacement amount.

[0068] In some embodiments, the guiding assembly 20 includes a first assembly 210 and a second assembly 220. The driving member 201 of the first assembly 210 can drive a plurality of guiding rings 202 to approach or move away from each other in the first direction X, and the driving member 201 of the second assembly 220 can drive the plurality of guiding rings 202 to approach or move away from each other in the second direction Y. The first assembly 210 is disposed at the vehicle body component 40, and the second assembly 220 is disposed at the steering knuckle 50. The driving members 201 of both the first assembly 210 and the second assembly 220 have a telescopic power output portion 2011. The guiding ring 202 is connected to the power output portion 2011, and the power output portion 2011 drives the plurality of guiding rings 202 to approach or move away from each other.

[0069] The relationship between the extension amount L1 of the power output portion 2011 of the first assembly 210 and the outward deflection angle θ of the wheel relative to the vehicle body component 40 conforms to the following formula:

[0070] When 0 ≤ θ ≤ π / 8, L1 = k1 × θ; when π / 8 < θ ≤ π / 4, L1 = k1 × (π / 4 - θ); where the value range of the coefficient k1 is 0 < k1 ≤ 1.

[0071] And / or, the relationship between the extension amount L2 of the power output portion 2011 of the second assembly 220 and the displacement amount h of the wheel moving downward relative to the vehicle body component 40 conforms to the following formula:

[0072] L2 = k1 × h, where the value range of the coefficient k1 is 0 < k1 ≤ 1.5.

[0073] In this embodiment, when the wheel deflects outward relative to the vehicle body component 40, the power output portion 2011 of the driving member 201 of the first assembly 210 first gradually extends and then gradually retracts. Specifically, the maximum angle of the wheel deflecting outward relative to the vehicle body component 40 is generally 45°, that is, π / 4. At this time, the brake hose 10 is straightened, and the power output portion 2011 needs to be completely retracted to avoid misalignment between the guiding path and the straightened extension direction, damaging the brake hose 10 or the guiding assembly 20. In the above formula, when the deflection angle ranges from 0 to π / 8, the power output portion 2011 of the driving member 201 of the first assembly 210 gradually extends to drive the plurality of guiding rings 202 to move away from each other for guiding. When the deflection angle ranges from π / 8 to π / 4, the power output portion 2011 of the driving member 201 of the first assembly 210 gradually retracts.

[0074] When the wheel moves downward relative to the vehicle body component 40, the power output part 2011 of the driving part 201 of the second assembly 220 gradually extends. Specifically, when the vehicle is briefly suspended, the wheel moves downward relative to the vehicle body component 40, and the downward movement amount is limited. Generally, the brake hose 10 will not be straightened. Therefore, the power output part 2011 of the driving part 201 of the second assembly 220 gradually extends with the downward movement amount of the wheel, thereby driving the plurality of guide rings 202 to move away from each other to guide the brake hose 10.

[0075] In particular, the term "and / or" in the present application should be understood as follows:

[0076] In the first case, the term "and / or" between the first main body and the second main body includes any one of the following meanings: (1) only the first main body; (2) only the second main body; and (3) the first main body and the second main body.

[0077] In the second case, the term "and / or" between the last two of three or more main bodies means including at least any one of the plurality of main bodies. For example, "the first main body, the second main body and / or the third main body" has the same meaning as "the first main body and / or the second main body and / or the third main body", and specifically includes the following combinations: (1) only the first main body; (2) only the second main body; (3) only the third main body; (4) the first main body and the second main body without the third main body; (5) the first main body and the third main body without the second main body; (6) the second main body and the third main body without the first main body; and (7) the first main body, the second main body and the third main body;

[0078] In addition, the character " / " in the present application indicates that the related objects before and after it are in an "or" relationship.

[0079] Finally, although the embodiments of the present application have been described in conjunction with the accompanying drawings, those skilled in the art can also make various modifications and variations without departing from the concept of the present application. Then such modifications and variations all fall within the scope protected by the present application.
