Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a braking assembly, a braking system, and a vehicle. Background Technology

[0002] The master cylinder is a key component of the automotive braking system. The force applied to the pedal pushes the piston in the master cylinder forward, generating hydraulic pressure. This hydraulic pressure is then supplied to the entire vehicle's braking system through the master cylinder outlet, thus achieving braking. The master cylinder piston and piston rod are connected by a ball joint, allowing the piston rod to swing freely relative to the master cylinder piston.

[0003] In related technologies, the ball end of the push rod is usually installed into the ball groove of the master cylinder piston by pressing. However, the above installation method will result in an installation gap between the ball end and the ball groove. When the driver releases the brake pedal, there will be an impact noise at the connection position between the master cylinder piston and the piston push rod, which will affect the user experience. Utility Model Content

[0004] This disclosure aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, embodiments of this disclosure propose a braking assembly that can eliminate the problem of abnormal noise at the connection position between the master cylinder piston and the push rod, and the push rod swings flexibly, resulting in a better user experience.

[0006] Embodiments of this disclosure also propose a braking system.

[0007] Embodiments of this disclosure also propose a vehicle.

[0008] The braking assembly of this disclosure includes: a master cylinder piston having a ball groove therein; a push rod including a rod body and a ball head, the rod body having a first end and a second end, the ball head being connected to the first end of the rod body and engaging within the ball groove; and an elastic member disposed in the ball groove and abutting between the ball head and the master cylinder piston, the elastic member being used to apply a first elastic force and a second elastic force to the ball head, the first elastic force being directed along the second end of the rod body toward the first end of the rod body, and the second elastic force being used to restrict the ball head from swinging relative to the ball groove.

[0009] According to the braking assembly of the embodiments of this disclosure, since the direction of the elastic element is along the second end of the rod towards the first end of the rod, the reliability of the contact between the ball head and the ball groove can be ensured, thereby avoiding the problem of gaps between the ball head and the ball groove and the resulting impact noise when the brake pedal is released. Furthermore, the first and second elastic forces exert different constraints on the ball head and do not affect each other, allowing for a certain degree of flexibility in the ball head's movement within the ball groove. This helps reduce the pressure required for the user to press the brake pedal and improves the user experience.

[0010] In some embodiments, the second elastic force is less than the first elastic force. This reduces the downward pressure required for the user to press the brake pedal, and the ball head, under the action of the first elastic force, can firmly abut against the ball groove, reducing the rebound amplitude of the brake pedal and thus avoiding triggering a secondary braking signal.

[0011] In some embodiments, the elastic element includes at least two rings arranged sequentially along the axial direction of the rod. Each ring includes a crest and a trough, with the crest of one ring and the trough of another ring arranged opposite to each other along the axial direction of the rod. By arranging the elastic element in the above-described structure, the braking assembly of the embodiments of this disclosure allows the ball head to compress the crest when it swings relative to the ball groove, enabling the ring to swing around the trough as a fulcrum, thereby reducing the downward force required for the user to depress the brake pedal.

[0012] In some embodiments, the elastic element is spirally arranged to form at least two rings. This makes the elastic element stable when transmitting the first and second elastic forces, and facilitates manufacturing.

[0013] In some embodiments, two adjacent rings are arranged symmetrically. This makes the elastic element more stable when transmitting the second elastic force and facilitates manufacturing.

[0014] In some embodiments, the ring body curves upwards along at least one side of a first direction toward the ball head to form the crest, and the ring body curves upwards along at least one side of a second direction away from the ball head to form the trough. Both the first and second directions are orthogonal to the axial direction of the rod body, and there is an angle between the first and second directions. The braking assembly of the embodiments of this disclosure, by designing the elastic element with the above-described structure, facilitates the manufacturing of the elastic element, ensures stable contact between the elastic element and the ball head, and reduces the second elastic force experienced by the ball head during swinging.

[0015] In some embodiments, the elastic element includes a first ring and a second ring capable of elastic deformation. The first ring has a first crest and a first trough spaced apart along its circumference, and the second ring has a second crest and a second trough spaced apart along its circumference. The first crest protrudes towards and connects with the ball head, and the second ring is located on the side of the first ring away from the ball head. The second trough protrudes away from the ball head and connects with the master cylinder piston. Because the first crest of the first ring protrudes towards and connects with the ball head, and the second trough of the second ring protrudes away from the ball head and connects with the master cylinder piston, the stability of the elastic element after installation is ensured. Furthermore, by providing the above-described structure for the elastic element, the axial force of the elastic element can be increased, while the impact on the rotational force of the elastic element is relatively small, resulting in better performance.

[0016] In some embodiments, there are at least two first crests arranged along a first direction on both sides of the first ring, and at least two first troughs arranged along a second direction on both sides of the first ring, wherein the first direction, the second direction, and the axial direction of the rod are orthogonal to each other. The braking assembly of the embodiments of this disclosure, by designing the elastic element with the above-described structure, can achieve better stability when the first ring engages with the ball head, and more balanced force when the ball head swings.

[0017] In some embodiments, the elastic element further includes a third ring capable of elastic deformation, the third ring being disposed between the first ring and the second ring, the third ring having third peaks and third troughs spaced apart along its circumference, the third peaks connecting to the first troughs and the third troughs connecting to the second peaks. By designing the elastic element with the above-described structure, the braking assembly of the embodiments of this disclosure can increase the first elastic force of the elastic element while having a smaller impact on the second elastic force, thereby reducing the rebound amplitude of the brake pedal, avoiding triggering a secondary braking signal, and also improving the stability of the elastic element under stress.

[0018] A braking system according to another embodiment of the present disclosure includes: a braking assembly, which is the braking assembly described in any one of the embodiments of the present disclosure; a brake cylinder, wherein the master cylinder piston is slidably connected to the brake cylinder; and a brake pedal, which is rotatably connected to the second end of the lever.

[0019] According to the braking system of the embodiments of this disclosure, since the direction of the elastic element is along the second end of the rod towards the first end of the rod, the reliability of the contact between the ball head and the ball groove can be ensured, thereby avoiding the problem of gaps between the ball head and the ball groove and the resulting impact noise when the brake pedal is released. In addition, the first elastic force and the second elastic force have different restraining effects on the ball head and do not affect each other, which allows the ball head to maintain a certain degree of flexibility in swinging within the ball groove, which helps to reduce the pressure required for the user to press the brake pedal and improves the user experience.

[0020] Another embodiment of the vehicle disclosed herein includes the braking system described in the embodiments of the present disclosure.

[0021] In the vehicle according to the embodiments of this disclosure, since the direction of the elastic element is along the second end of the rod towards the first end of the rod, the reliability of the contact between the ball head and the ball groove can be ensured, thereby avoiding the problem of gaps forming between the ball head and the ball groove and causing impact noise when the brake pedal is released. In addition, the first elastic force and the second elastic force have different restraining effects on the ball head and do not affect each other, which allows the ball head to retain a certain degree of flexibility in swinging within the ball groove, which helps to reduce the pressure required for the user to press the brake pedal and improve the user experience.

[0035] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0036] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0037] The following is a reference appendix. Figures 1 to 7 This disclosure describes braking components, braking systems, and vehicles according to embodiments of the present disclosure.

[0038] like Figure 1 As shown, the braking assembly of this embodiment includes a master cylinder piston 1, a push rod 2, and an elastic member 3. The master cylinder piston 1 has a ball groove 11. The push rod 2 includes a rod body 21 and a ball head 22. The rod body 21 has a first end and a second end. The ball head 22 is connected to the first end of the rod body 21 and fits in the ball groove 11. The elastic member 3 is disposed in the ball groove 11 and abuts against the ball head 22 and the master cylinder piston 1. The elastic member 3 is used to apply a first elastic force and a second elastic force to the ball head 22. The direction of the first elastic force is along the second end of the rod body 21 toward the first end of the rod body 21. The second elastic force is used to limit the swing of the ball head 22 relative to the ball groove 11.

[0039] According to the braking assembly of the embodiments of this disclosure, since the direction of the elastic member 3 is along the second end of the rod 21 toward the first end of the rod 21, the reliability of the contact between the ball head 22 and the ball groove 11 can be ensured, so as to avoid the problem of gaps between the ball head 22 and the ball groove 11 and the abnormal impact noise when the brake pedal 5 is released. In addition, the first elastic force and the second elastic force have different restraining effects on the ball head 22 and do not affect each other, which can retain a certain degree of flexibility for the ball head 22 to swing in the ball groove 11, which helps to reduce the pressure required for the user to step on the brake pedal 5 and improve the user experience.

[0040] It is understandable that the first and second elastic forces applied by the elastic element 3 to the ball head 22 are decoupled from each other and do not affect each other. Thus, the first and second elastic forces can be designed as needed, which can reduce the abnormal noise generated by the impact between the ball head 22 and the ball groove 11, and also allow the ball head 22 to retain a certain degree of flexibility in swinging within the ball groove 11.

[0041] Optionally, the second elastic force is less than the first elastic force. By designing the second elastic force (i.e., rotational force) to be less than the first elastic force, the braking assembly of the present disclosure can reduce the downward pressure required for the user to press the brake pedal 5, and the ball head 22 can firmly abut against the ball groove 11 under the action of the first elastic force, which can reduce the rebound amplitude of the brake pedal 5, thereby avoiding triggering a secondary braking signal.

[0042] like Figure 7 As shown, P1 represents the initial position of brake pedal 5 after it is released, and P2 represents the position of brake pedal 5 during the second braking action after the pedal has rebounded. Figure 7 It is known that the brake pedal 5 will not trigger the switch signal under the action of the elastic element 3 disclosed herein, that is, it will not generate a secondary braking signal, thus avoiding the problem that the vehicle start function will not be triggered due to the generation of a secondary braking signal when the vehicle is in launch mode (quickly releasing the brake pedal and then quickly pressing the accelerator pedal).

[0043] like Figure 2 As shown, the elastic element 3 is a wave spring. Based on the structural characteristics of the wave spring, the first and second elastic forces can be decoupled, and the second elastic force (i.e., rotational force) can be designed to be relatively small. Furthermore, increasing the first elastic force of the wave spring will not lead to an increase in the second elastic force, thus ensuring that the ball head 22 firmly abuts against the ball groove 11, reducing the rebound amplitude of the brake pedal 5, thereby avoiding triggering a secondary braking signal. Additionally, the push rod 2 can swing flexibly, facilitating the driver's use of the brake pedal 5 and improving the driving experience.

[0044] like Figures 2-6 As shown, the elastic element 3 includes at least two rings 301 arranged sequentially along the axial direction of the rod 21. Each ring 301 includes a crest 302 and a trough 303. In two adjacent rings 301, the crest 302 of one ring 301 and the trough 303 of the other ring 301 are arranged opposite to each other along the axial direction of the rod 21. By arranging the elastic element 3 in the above-described structure, the braking assembly of this embodiment allows the ball head 22 to compress the crest 302 when the ball head 22 swings relative to the ball groove 11, enabling the ring 301 to swing around the trough 303 as a fulcrum, thereby reducing the downward force required for the user to press the brake pedal 5.

[0045] For example, the number of rings 301 can be two, three, or more. Figure 4 and Figure 5 As shown, there are two rings 301. Figure 2 and Figure 3 As shown, there are three rings 301, as follows: Figure 6 As shown, there are four rings 301. This disclosure does not specify the number of rings 301, and the number can be adjusted according to actual needs.

[0046] In one example, such as Figure 2 and Figure 3 As shown, the elastic element 3 is spirally arranged to form at least two rings 301. In other words, the elastic element 3 is spiral-shaped, and the two rings 301 are connected sequentially along the spiral direction. This makes the elastic element 3 more stable in transmitting the first and second elastic forces, and also facilitates its manufacturing. In the example of this disclosure, as... Figure 2 and Figure 3 As shown, the elastic element 3 is spirally arranged to form three rings 301.

[0047] In another example, such as Figure 4 and Figure 5 As shown, two adjacent rings 301 are arranged symmetrically. That is, two adjacent rings 301 are symmetrical about a plane of symmetry, which is orthogonal to the axial direction of the rod 21. In the aforementioned example, the two rings 301 can be separate structures, then symmetrically joined together (e.g., by welding or bonding). This allows the axial length of the elastic element 3 to be changed by adjusting the number of rings 301. Alternatively, the two rings 301 can be integrally formed, which is also within the scope of this disclosure.

[0048] like Figure 2 and Figure 3 As shown, the ring 301 curves upwards along at least one side of the first direction toward the ball head 22 to form a crest 302, and the ring 301 curves upwards along at least one side of the second direction away from the ball head 22 to form a trough 303. Both the first and second directions are orthogonal to the axis of the rod 21, and there is an angle between the first and second directions. It can be understood that the ring 301 has an undulating wave shape along its circumference. The braking assembly of the embodiments of this disclosure, by designing the elastic element 3 with the above-described structure, facilitates the manufacturing of the elastic element 3, and ensures stable contact between the elastic element 3 and the ball head 22, resulting in a smaller second elastic force on the ball head 22 during swing. Optionally, the ring 301 has a uniform thickness along its circumference, which facilitates processing and provides more stable force distribution. Of course, the thickness of the ring 301 can also be inconsistent, which is also within the scope of this disclosure.

[0049] Optionally, such as Figure 2 and Figure 3 As shown, the elastic element 3 includes a first ring 31 and a second ring 32 that can undergo elastic deformation. The first ring 31 has a first crest 311 and a first trough 312 arranged at intervals along its circumference. The second ring 32 has a second crest 321 and a second trough 322 arranged at intervals along its circumference. The first crest 311 protrudes toward the ball head 22 and is in contact with the ball head 22. The second ring 32 is located on the side of the first ring 31 away from the ball head 22. The second trough 322 protrudes in the direction away from the ball head 22 and is in contact with the master cylinder piston 1.

[0050] Since the first peak 311 of the first ring 31 protrudes towards the ball head 22 and connects with the ball head 22, and the second trough 322 of the second ring 32 protrudes away from the ball head 22 and connects with the master cylinder piston 1, the stability of the elastic element 3 after installation is ensured.

[0051] It is understandable that when the ball head 22 of the push rod 22 swings relative to the ball groove 11, the ball head 22 can squeeze the first crest 311, causing the first ring 31 to swing along the first trough 312 as a fulcrum. At this time, the angle formed between the first crest 311 and the horizontal plane orthogonal to the rod body 21 will decrease or increase accordingly. The braking assembly of the embodiment of this disclosure, by adopting the above-described structure for the elastic element 3, can increase the axial force (first elastic force) of the elastic element 3 and has a smaller impact on the rotational force (second elastic force), resulting in better performance.

[0052] In other words, when the ball head 22 swings relative to the ball groove 11, the first ring 31 can swing around the first trough 312 as a fulcrum. It can be understood that when the ball head 22 swings relative to the ball groove 11, the ball head 22 can compress the first crest 311, causing the first ring 31 to swing around the first trough 312 as a fulcrum. Compared to the cylindrical spring solution in related technologies, the elastic element 3 of the embodiment of this disclosure can reduce the second elastic force of the elastic element 3, thus preserving a certain degree of flexibility for the ball head 22 to swing within the ball groove 11.

[0053] Furthermore, the first elastic force and the second elastic force of the elastic element 3 in the embodiments of this disclosure do not have a binding characteristic, that is, the first elastic force and the second elastic force are decoupled from each other and can be designed separately as needed. For example, the axial spacing between the first crest 311 and the second trough 322 can be increased to reduce the second elastic force. As another example, the thickness of the first ring 31 can be reduced to reduce the second elastic force.

[0054] like Figure 4 and Figure 5 As shown, taking a scheme with two rings 301, namely the first ring 31 and the second ring 32, as an example. The second trough 322 is opposite to and spaced apart from the first peak 311 along the axial direction of the rod 21, and the second peak 321 abuts against the first trough 312 along the axial direction of the rod 21. When the ball head 22 swings relative to the ball groove 11, the ball head 22 can squeeze the first peak 311, so that the first ring 31 swings along the first trough 312 as the fulcrum. At this time, the included angle formed between the first peak 311 and the second trough 322 will decrease or increase accordingly.

[0055] For example, such as Figure 2 and Figure 3As shown, there are at least two first wave peaks 311 arranged along a first direction on both sides of the first ring 31, and at least two first wave troughs 312 arranged along a second direction on both sides of the first ring 31. The first direction, the second direction, and the axis of the rod 21 are orthogonal to each other. It can be understood that the two first wave peaks 311 are arranged radially symmetrically along the first ring 31, and the two second wave troughs 312 are arranged radially symmetrically along the first ring 31. By designing the elastic element 3 with the above-described structure, the braking assembly of the embodiment of this disclosure can achieve better stability when the first ring 31 engages with the ball head 22, and the force on the ball head 22 is balanced when it swings.

[0056] In other examples, there may be more than two first peaks 311 and first troughs 312. For example, there may be three or four first peaks 311 and first troughs 312. The number of first troughs 312 is equal to the number of first peaks 311. Multiple first peaks 311 and multiple first troughs 312 are arranged at equal intervals and alternately along the circumference of the first ring 31. Multiple first troughs 312 are arranged symmetrically around the center point of the first ring 31, and multiple first peaks 311 are arranged symmetrically around the center point of the first ring.

[0057] like Figure 2 and Figure 3 As shown, in a projection plane orthogonal to the axis of the rod 21, the outer contour of the first ring 31 is circular. The first ring 31 curves upwards on both sides along the first direction toward the ball head 22 to form two first peaks 311, and the first ring 31 curves upwards on both sides along the second direction away from the ball head 22 to form two first troughs 312. It can be understood that the thickness of the first ring 31 is constant along its circumference, and the first ring 31 has an undulating wave shape along its circumference. The braking assembly of the embodiment of this disclosure, by designing the elastic element 3 with the above structure, facilitates the processing and manufacturing of the elastic element 3, and the contact between the elastic element 3 and the ball head 22 is stable, resulting in a smaller second elastic force on the ball head 22 when it swings. Of course, the thickness of the first ring 31 can also be inconsistent, which is also within the protection scope of this disclosure.

[0058] For example, the outer periphery of the cross-section of the first ring 31 is rectangular. It can be understood that the first ring 31 is generally a hollow thin circular sheet structure to facilitate the processing and manufacturing of the first ring 31.

[0059] like Figure 4 and Figure 5 As shown, taking a scheme with two rings 301, namely a first ring 31 and a second ring 32, as an example. The first ring 31 and the second ring 32 are arranged symmetrically. For example, the first ring 31 and the second ring 32 are separate structures, and then the first ring 31 and the second ring 32 can be connected by welding or bonding. Since the first ring 31 and the second ring 32 are arranged symmetrically, it is convenient to process and manufacture the elastic element 3, and the stability under stress is better.

[0060] In another example, the elastic element 3 has a spiral structure, with the trough 303 of the first ring 31 connected to the crest 302 of the second ring 32. That is, the elastic element 3 can be a one-piece molded structure, with the first ring 31 and the second ring 32 extending in a spiral shape. This makes the elastic element 3 more stable in transmitting the first and second elastic forces, and also facilitates processing and manufacturing.

[0061] In some embodiments, such as Figure 2 and Figure 3 As shown, the elastic element 3 also includes a third ring 33 capable of elastic deformation. The third ring 33 is disposed between the first ring 31 and the second ring 32, and the third ring 33 has third crests 331 and third troughs 332 spaced apart along its circumference. By providing the third ring 33, the braking assembly of the embodiment of this disclosure can increase the axial length of the elastic element 3 to accommodate different types of push rods 2 and ball grooves 11. Furthermore, the arrangement of the third ring 33 can increase the axial force (first elastic force) of the elastic element 3, while having a smaller impact on the rotational force (second elastic force), resulting in better performance.

[0062] like Figure 2 and Figure 3 As shown, taking a configuration with three rings 301, i.e., one third ring 33, as an example, the third peak 331 connects to the first trough 312 along the axial direction of the rod 21, and the third trough 332 connects to the second peak 321 along the axial direction of the rod 21. The braking assembly of this embodiment, by designing the elastic element with the above-described structure, can increase the first elastic force of the elastic element while minimizing its impact on the second elastic force, thereby reducing the rebound amplitude of the brake pedal, avoiding triggering a secondary braking signal, and improving the stability of the elastic element under stress.

[0063] It should be noted that there can be one or more third rings 33, all of which are within the scope of protection of this disclosure. For example... Figure 6 As shown, when there are multiple third rings 33, the multiple third rings 33 are arranged sequentially along the axial direction of the rod 21. This disclosure does not specify the number of third rings.

[0064] Optionally, such as Figure 1As shown, the ball head 22 has a first contact plane 221 on the side facing the second end of the rod 21, and the master cylinder piston 1 has a second contact plane 12 on the side facing the second end of the rod 21. The elastic element 3 is installed between the first contact plane 221 and the second contact plane 12. Since both the first contact plane 221 and the second contact plane 12 are planar structures, and the elastic element 3 abuts against the first contact plane 221 and the second contact plane 12, the noise generated when the elastic element 3 slides against the ball head 22 and the piston can be reduced. That is, the elastic element 3 is more stable when extending or retracting and is less prone to shaking, thus avoiding the problem of abnormal noise from the elastic element 3 during vehicle operation.

[0065] Another embodiment of the braking system disclosed herein includes: a braking assembly, a brake cylinder 4, and a brake pedal 5. The braking assembly is the braking assembly of this disclosure. The master cylinder piston 1 is slidably connected to the brake cylinder 4, and the brake pedal 5 is rotatably connected to the second end of the rod 21.

[0066] According to the braking system of the embodiments of this disclosure, since the direction of the elastic member 3 is along the second end of the rod 21 toward the first end of the rod 21, the reliability of the contact between the ball head 22 and the ball groove 11 can be ensured, so as to avoid the problem of gaps between the ball head 22 and the ball groove 11 and the abnormal impact noise when the brake pedal 5 is released. In addition, the first elastic force and the second elastic force have different restraining effects on the ball head 22 and do not affect each other, which can retain a certain degree of flexibility for the ball head 22 to swing in the ball groove 11, which helps to reduce the pressure required for the user to step on the brake pedal 5 and improve the user experience.

[0067] Another embodiment of the vehicle disclosed herein includes the braking system of this disclosure. The technical advantages of the vehicle of this embodiment are the same as those of the braking system of the above embodiments, and will not be repeated here.

They are used only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0069] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0070] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly.
