When parking, the motor drive assembly 210 pushes the piston transmission assembly 220, which in turn pushes the friction plate assembly 230, which locks the brake disc, thus completing the parking process.

[0005] The problems with manual cable parking mechanisms and motor-driven parking mechanisms are: complex structure and numerous parts, resulting in long development cycles and high costs.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] This application provides a hydraulic parking mechanism and an integrated braking control system and an electromechanical braking system configured with the hydraulic parking mechanism. The hydraulic parking mechanism of this application has a simple structural design and control method, is lightweight, can achieve convenient and reliable control, and achieves a lightweight design, reducing the manufacturing cost of the integrated braking control system and the electromechanical braking system, and improving braking performance.

[0008] According to one aspect of this application, a hydraulic parking mechanism is provided, including a piston and a control assembly. The control assembly includes: a housing with a built-in hydraulic channel communicating with the piston; a movable push rod assembly disposed in the housing, the push rod assembly having a recessed portion relative to its body; and a resettable sealing assembly disposed in the hydraulic channel and cooperating with the push rod assembly and the hydraulic channel. When the body of the push rod assembly abuts against the sealing assembly, the hydraulic channel is opened; when the sealing assembly abuts against the recess of the push rod assembly, the wall surface of the sealing assembly seals against the wall surface of the hydraulic channel, and the hydraulic channel is closed.

[0009] The push rod assembly has a recessed portion relative to the body, providing space for the sealing assembly to move. The sealing assembly has a reset capability, allowing it to move according to changes in its position relative to the push rod assembly, altering the fit between the sealing assembly's wall and the hydraulic passage's wall, thereby controlling the opening and closing of the hydraulic passage. When the push rod assembly moves to the point where it abuts against the sealing assembly, the sealing assembly and hydraulic passage are separated, and the hydraulic passage is open. At this time, the output of braking force can be controlled by adjusting the hydraulic pressure in the hydraulic passage, achieving braking or releasing the parking brake. When the push rod assembly moves to the point where it aligns with the recessed portion of the sealing assembly, the sealing assembly moves under the reset action to abut against the recessed portion of the push rod assembly. At this time, the sealing assembly's wall and the hydraulic passage's wall seal together, closing the hydraulic passage. Meanwhile, the hydraulic pressure in the chamber connected to the piston can be maintained to sustain the braking state, achieving the parking function.

[0010] In some embodiments, the control assembly is an electromagnetic control assembly to achieve convenient and reliable control.

[0011] In some embodiments, the push rod assembly includes a control rod having the recess and an electromagnetic push rod connected to the control rod; wherein the electromagnetic push rod can drive the control rod to move so that the control rod moves to the point where the body portion abuts against the sealing assembly, or so that the control rod moves to the point where the recess aligns with the sealing assembly. The combination of the electromagnetic push rod and the control rod achieves reliable and precise stroke drive.

[0012] In some embodiments, the recess is an annular recess, which eliminates the need to specifically find the angle when assembling the push rod assembly, and allows it to cooperate with the sealing assembly at any assembly angle.

[0013] In some embodiments, the push rod assembly and the housing are sealed together by a first sealing ring to prevent hydraulic oil from leaking along the gap between the push rod assembly and the housing.

[0014] In some embodiments, the sealing assembly includes: a sealing core, a first end of which engages with the push rod assembly, and a wall surface of the sealing core engaging with the wall surface of the hydraulic channel; and a return spring connecting a second end of the sealing core to the piston; wherein, when the push rod assembly moves to the point where the recess aligns with the sealing core, the sealing core moves under the action of the return spring to abut against the recess. Through the engagement of the return spring and the sealing core, and the engagement of the sealing core's wall surface with the wall surface of the hydraulic channel, the sealing assembly achieves the shut-off and opening of the hydraulic channel.

[0015] In some embodiments, a second sealing ring is provided on the wall surface of the sealing core; when the first end of the sealing core abuts against the recess, the wall surface of the sealing core and the wall surface of the hydraulic channel are sealed together by the second sealing ring. As the wall surface of the sealing core contacts and presses against the wall surface of the hydraulic channel, the second sealing ring deforms, tightly fitting against the wall surface of the hydraulic channel, thus shutting off the passage between the two ends of the hydraulic channel.

[0016] In some embodiments, both the wall surface of the sealing core and the wall surface of the hydraulic channel are formed as conical surfaces. Utilizing the conical surface engagement, when the sealing core is pushed away by the body of the push rod assembly, the wall surface of the sealing core moves away from the wall surface of the hydraulic channel; when the sealing core moves towards the recess of the push rod assembly, the wall surface of the sealing core gradually approaches, contacts, and presses against the wall surface of the hydraulic channel to shut off the hydraulic channel.

[0017] In some embodiments, the piston has a mounting groove at its end, and the mounting groove has a passage connecting the hydraulic channel and the piston's movable core; the second end of the sealing core extends into the mounting groove, and the return spring is sleeved on the outside of the second end of the sealing core and abuts against the mounting groove. By utilizing the design of the second end of the sealing core extending into the piston's mounting groove and the return spring being arranged in the mounting groove, a compact and stable mating structure is achieved, making the entire mechanism more integrated and miniaturized.

[0018] In some embodiments, the piston is mounted in a brake caliper body, the control assembly is mounted on the brake caliper body and connected to a first end of the piston, and a friction pad assembly is provided at a second end of the piston. Under the hydraulic pressure of the hydraulic channel, the piston can drive the friction pad assembly to move, thereby clamping or releasing the brake disc, realizing the functions of braking, parking, and releasing the parking brake.

[0019] According to another aspect of this application, an integrated braking control system is provided, the integrated braking control system being configured with a hydraulic parking mechanism as described in any of the above embodiments.

[0020] According to another aspect of this application, an electromechanical braking system is provided, the electromechanical braking system being configured with a hydraulic parking mechanism as described in any of the above embodiments.

[0021] The integrated braking control system / electromechanical braking system is equipped with the aforementioned hydraulic parking mechanism. Through the cooperation of the push rod assembly with a recess and the resettable sealing assembly, and in conjunction with the design of the hydraulic channel, it can realize the on-off control of the hydraulic channel. The overall structure is simple and lightweight, the control is convenient and efficient, the cost is effectively reduced, and reliable braking, parking, and release functions are achieved.

Furthermore, in the description of this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components.

[0033] It should be noted that, unless otherwise specified, the embodiments of this application and the features in different embodiments can be combined with each other.

[0034] Figure 3 The structure of the hydraulic parking mechanism is illustrated. Figure 4 The structure of the control assembly is shown. Figure 5 and Figure 6 The cross-sectional views of the control assembly are shown in both the on and off states of the hydraulic channel; combined with Figures 3 to 6 As shown, the hydraulic parking mechanism provided in this application embodiment includes a piston 300 and a control assembly 400, the control assembly 400 including:

[0035] The housing 410 has a built-in hydraulic channel 412 that connects to the piston 300;

[0036] A movable push rod assembly 420 is disposed in the housing 410, and the push rod assembly 420 is provided with a recess 422b that is recessed relative to the body portion 422a;

[0037] A resettable sealing assembly 430 is disposed in the hydraulic channel 412 and cooperates with the push rod assembly 420 and the hydraulic channel 412;

[0038] When the body portion 422a of the push rod assembly 420 abuts against the sealing assembly 430, the hydraulic channel 412 is opened;

[0039] When the sealing assembly 430 abuts against the recess 422b of the push rod assembly 420, the wall surface of the sealing assembly 430 seals against the wall surface of the hydraulic channel 412, and the hydraulic channel 412 is shut off.

[0040] The push rod assembly 420 is movably disposed within the housing 410. By controlling the push rod assembly 420 to move to different positions, the mating relationship between the push rod assembly 420 and the sealing assembly 430 can be changed, thereby altering the opening and closing of the hydraulic passage 412. Specifically, the push rod assembly 420 has a recess 422b that is recessed relative to the body portion 422a, providing movement space for the sealing assembly 430. The sealing assembly 430 has a reset capability and can move according to changes in its positional relationship with the push rod assembly 420, changing the mating relationship between the wall surface of the sealing assembly 430 and the wall surface of the hydraulic passage 412, thereby controlling the opening and closing of the hydraulic passage. When the push rod assembly 420 moves to the point where the body portion 422a abuts against the sealing assembly 430, the sealing assembly 430 is separated from the hydraulic passage 412, and the hydraulic passage 412 is open. At this time, the output of braking force can be controlled by adjusting the hydraulic pressure in the hydraulic passage 412, achieving braking (increasing the hydraulic pressure in the hydraulic passage 412) or releasing the parking brake (decreasing the hydraulic pressure in the hydraulic passage 412). When the push rod assembly 420 moves to the position where the recess 422b aligns with the sealing assembly 430, the sealing assembly 430 moves to abut against the recess 422b of the push rod assembly 420 under the reset action, so that the wall surface of the sealing assembly 430 seals against the wall surface of the hydraulic channel 412, thereby closing the hydraulic channel 412; at this time, the hydraulic pressure in the chamber connected to the piston 300 can be maintained to maintain the braking state and realize the parking function.

[0041] Therefore, this application achieves on / off control of the hydraulic channel 412 by cooperating with the push rod assembly 420 with the recess 422b and the resettable sealing assembly 430, and in conjunction with the design of the hydraulic channel 412. The structure is simple and lightweight, the control is convenient and efficient, and it can reliably achieve braking, parking, and release functions. The hydraulic parking mechanism of this application can be applied to integrated braking control systems, electromechanical braking systems, and other braking systems, achieving a simple and lightweight design, reducing manufacturing and control costs, and improving braking performance.

[0042] In some embodiments, the control assembly 400 is an electromagnetic control assembly to achieve convenient and reliable control. In other embodiments, the motion control of the push rod assembly 420 can also be achieved through other control methods.

[0043] In some embodiments, the push rod assembly 420 includes a control rod 422 with a recess 422b and an electromagnetic push rod 421 connected to the control rod 422. The electromagnetic push rod 421 can drive the control rod 422 to move, causing the control rod 422 to abut against the sealing assembly 430 at its body portion 422a, or to align the control rod 422 with the sealing assembly 430 at the recess 422b. An electromagnetic control component 4210 is provided on the electromagnetic push rod 421. The electromagnetic control component 4210 can control the movement of the electromagnetic push rod 421 between different positions according to an electrical signal, thereby driving the control rod 422 to move and changing the positional relationship between the control rod 422 and the sealing assembly 430, thus achieving on / off control of the hydraulic channel 412. The combination of the electromagnetic push rod 421 and the control rod 422 achieves reliable and precise stroke drive.

[0044] In some embodiments, the recess 422b is an annular recess, so that the push rod assembly 420 does not need to be specially angled during assembly, and can cooperate with the sealing assembly 430 at any assembly angle.

[0045] In some embodiments, the push rod assembly 420 and the housing 410 are sealed together by a first sealing ring 440 to prevent hydraulic oil from leaking along the gap between the push rod assembly 420 and the housing 410, thereby ensuring the stability of hydraulic pressure and thus ensuring the reliable operation of the hydraulic parking mechanism.

[0046] In some embodiments, the sealing assembly 430 includes: a sealing core 431, with a first end 431a cooperating with a push rod assembly 420, and a wall surface 431c of the sealing core 431 cooperating with a wall surface 412c of the hydraulic channel 412; and a return spring 432 connecting a second end 431b of the sealing core 431 to a piston 300. When the push rod assembly 420 moves to the point where the recess 422b aligns with the sealing core 431, the sealing core 431 moves to abut against the recess 422b under the action of the return spring 432. Through the cooperation of the return spring 432 and the sealing core 431, and the cooperation of the wall surface 431c of the sealing core 431 with the wall surface 412c of the hydraulic channel 412, the sealing assembly 430 can achieve the shut-off and opening of the hydraulic channel 412.

[0047] Specifically, when the push rod assembly 420 moves to the point where the body part 422a abuts against the sealing core 431, the wall surface 431c of the sealing core 431 is spaced apart from the wall surface 412c of the hydraulic channel 412, and the hydraulic channel 412 is open. At this time, the return spring 432 is in a stored state. When the push rod assembly 420 moves to the point where the recess 422b is aligned with the sealing assembly 430, the return spring 432 pushes the sealing core 431 to reset. As the sealing core 431 moves toward the recess 422b of the push rod assembly 420, the wall surface 431c of the sealing core 431 gradually approaches, contacts and presses against the wall surface 412c of the hydraulic channel 412, causing the hydraulic channel 412 to close.

[0048] The wall surface 431c of the sealing core 431 and the wall surface 412c of the hydraulic channel 412 can be designed to match each other. When the sealing core 431 is pushed away by the body part 422a of the push rod assembly 420, the wall surface 431c of the sealing core 431 leaves the wall surface 412c of the hydraulic channel 412. When the sealing core 431 moves toward the recess 422b of the push rod assembly 420, the wall surface 431c of the sealing core 431 gradually approaches, contacts and presses against the wall surface 412c of the hydraulic channel 412, thereby closing the hydraulic channel 412.

[0049] In other embodiments, the resetting of the sealing assembly 430 can also be achieved through electronic control or other suitable structural design.

[0050] In some embodiments, a second sealing ring 433 is provided on the wall surface 431c of the sealing core 431. When the first end 431a of the sealing core 431 abuts against the recess 422b, the wall surface 431c of the sealing core 431 and the wall surface 412c of the hydraulic channel 412 are sealed together by the second sealing ring 433. As the wall surface 431c of the sealing core 431 contacts and presses against the wall surface 412c of the hydraulic channel 412, the second sealing ring 433 deforms and tightly fits against the wall surface 412c of the hydraulic channel 412, shutting off the passage between the two ends of the hydraulic channel 412.

[0051] In some embodiments, the wall surface 431c of the sealing core 431 and the wall surface 412c of the hydraulic channel 412 are both formed as conical surfaces. Utilizing the conical surface fit, when the sealing core 431 is pushed away by the body portion 422a of the push rod assembly 420, the wall surface 431c of the sealing core 431 moves away from the wall surface 412c of the hydraulic channel 412; when the sealing core 431 moves towards the recess 422b of the push rod assembly 420, the wall surface 431c of the sealing core 431 gradually approaches, contacts, and presses against the wall surface 412c of the hydraulic channel 412, thereby shutting off the hydraulic channel 412. The conical surface fit also generates a greater sealing force than horizontal and vertical surfaces, improving the sealing effect. Furthermore, even with slight wear, the conical surface fit maintains good sealing performance, improving sealing reliability.

[0052] In some embodiments, the piston 300 has a mounting groove at its end, and a passage 311 is provided in the mounting groove to connect the hydraulic channel 412 and the movable core of the piston 300. The second end 431b of the sealing core 431 extends into the mounting groove, and the return spring 432 is sleeved on the outside of the second end 431b of the sealing core 431 and abuts against the mounting groove. By utilizing the design that the second end 431b of the sealing core 431 extends into the mounting groove of the piston 300 and the return spring 432 is arranged in the mounting groove, a compact and stable mating structure is achieved, making the entire mechanism more integrated and miniaturized.

[0053] In some embodiments, the piston 300 is mounted in the brake caliper body 500, and the control assembly 400 is mounted on the brake caliper body 500 and connected to the first end 300a of the piston 300. The second end 300b of the piston 300 is provided with a friction pad assembly 600. Under the hydraulic pressure of the hydraulic channel 412, the piston 300 can drive the friction pad assembly 600 to move, thereby clamping or releasing the brake disc and realizing the functions of braking, parking, and releasing the parking brake.

[0054] This application also provides an integrated brake control (IBC) system, which is equipped with a hydraulic parking mechanism as described in any of the above embodiments.

[0055] This application also provides an electro-mechanical braking (EMB) system, which is equipped with a hydraulic parking mechanism as described in any of the above embodiments.

[0056] The integrated braking control system / electromechanical braking system is equipped with the aforementioned hydraulic parking mechanism. Through the cooperation of the push rod assembly 420 with the recess 422b and the resettable sealing assembly 430, and in conjunction with the design of the hydraulic channel 412, the on / off control of the hydraulic channel 412 can be realized. The overall structure is simple and lightweight, the control is convenient and efficient, the cost is effectively reduced, and reliable braking, parking and release functions are achieved.

[0057] Specifically, if the vehicle needs to be parked, combined with Figure 3 , Figure 5 and Figure 6 As shown: When the integrated braking control system / electromechanical braking system issues a parking command, the dual-position electromagnetic push rod 421 pulls the control rod 422 to the left, aligning the recess 422b with the sealing core 431. The sealing core 431 then moves upward under the action of the return spring 432 until the second sealing ring 433 presses against the wall surface 431c of the sealing core 431 and the wall surface 412c of the hydraulic channel 412, shutting off the hydraulic channel 412 and disconnecting end A and end B of the hydraulic control path. At this time, the hydraulic pressure in the A-end pipeline is automatically released, while the hydraulic pressure at end B remains high due to the action of the return spring 432 and the second sealing ring 433, keeping the piston 300 in its original position. This keeps the friction pad assembly 600 locked in the brake disc state, achieving parking. If the vehicle needs to be released from parking, combined with... Figure 3 , Figure 5 and Figure 6As shown: When the integrated braking control system / electromechanical braking system issues a release command, the dual-position electromagnetic push rod 421 pushes the control rod 422 to the right, causing the main body 422a to abut against the sealing core 431. This drives the sealing core 431 and the second sealing ring 433 to move downwards, away from the wall 412c of the hydraulic channel 412, thereby opening the hydraulic channel 412 and connecting end A to end B. At this time, by controlling the hydraulic pressure at end A, the braking state of the vehicle can be controlled, such as releasing the parking brake and controlling the service brake.

[0058] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this application, and all such modifications or substitutions should be considered within the scope of protection of this application.
