[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] This application provides a vehicle that includes a windshield wiper 5, a parking brake 4, a drive motor, a first clutch 2, and a second clutch 3.

[0049] The windshield wiper 5 is a key component in a vehicle used to remove rainwater, snow, dust, and dirt from the windshield to ensure the driver has a clear view and thus ensure driving safety.

[0050] In an exemplary embodiment, the windshield wiper 5 includes a wiper body 501 and a first transmission mechanism 502. During operation, the wiper body 501 swings under the action of the first transmission mechanism 502 to clean the windshield.

[0051] The wiper body 501 can be a framed wiper, a frameless wiper, or a hybrid wiper; this application does not specifically limit this. Furthermore, the number of wiper bodies 501 can be adaptively adjusted as needed; for example, the number of wiper bodies 501 can be one or two, etc.

[0052] The first transmission mechanism 502 includes a wiper arm and a linkage system.

[0053] One end of the wiper arm is connected to the wiper body 501, and the other end is connected to the linkage system.

[0054] The specific structure of the linkage system can be adapted to the number of wiper arms, etc. Therefore, this application does not specifically limit the specific structure of the linkage system.

[0055] The parking brake 4 is the core device for vehicle parking braking.

[0056] For example, during implementation, the parking brake 4 can be a disc parking brake or a drum parking brake. In specific implementation, it can be adapted as needed, and this application does not make specific limitations in this regard.

[0057] In an exemplary embodiment, the parking device 4 includes a parking device body 401 and a second transmission mechanism 402.

[0058] The parking brake body 401 is the structure in the parking brake 4 used to perform the parking action. Its specific structure can be adapted to the type of parking brake 4, and this application does not make specific limitations in this regard.

[0059] The second transmission mechanism 402 is used to transmit parking power to the parking brake body 401. For example, the second transmission mechanism 402 can be a pull rope or steel cable, etc.

[0060] The drive motor is the power supply unit for the windshield wipers 5 and the parking brake 4. It has an output shaft for outputting torque.

[0061] like Figure 1 As shown, the first clutch 2 is used to connect the windshield wiper 5 and the output shaft of the drive motor.

[0062] The first clutch 2 has an engaged state and an disengaged state. In the engaged state of the first clutch 2, the wiper 5 is connected to the output shaft. That is, in the engaged state of the first clutch 2, the first clutch 2 can transmit the power output by the drive motor to the wiper 5, thereby driving the wiper 5 to work.

[0063] With the first clutch 2 disengaged, the wiper 5 is disconnected from the output shaft drive; that is, with the first clutch 2 disengaged, the power output by the drive motor cannot be transmitted to the wiper 5 through the first clutch 2. At this time, the drive motor cannot drive the wiper 5 to work.

[0064] like Figure 1 As shown, the second clutch 3 is used to connect the parking brake 4 and the output shaft.

[0065] The second clutch 3 has an engaged state and an disengaged state. When the second clutch 3 is engaged, the parking brake 4 is connected to the output shaft. That is, when the second clutch 3 is engaged, the second clutch 3 can transmit the power output by the drive motor to the parking brake 4, thereby driving the parking brake 4 to work.

[0066] With the second clutch 3 disengaged, the parking brake 4 is disconnected from the output shaft drive; that is, with the second clutch 3 disengaged, the power output by the drive motor cannot be transmitted to the parking brake 4 through the second clutch 3. At this time, the drive motor cannot drive the parking brake 4 to work.

[0067] It should be noted that, during implementation, the second clutch 3 and the first clutch 2 may be the same or different; this application does not impose specific limitations on this. For example, when the first clutch 2 is a ratchet clutch, the second clutch 3 may be a ratchet clutch or a roller-type one-way clutch.

[0068] As described above, in this embodiment, the first clutch 2 connects the output shaft of the drive motor and the windshield wiper 5, and the first clutch 2 also connects the output shaft of the drive motor and the parking brake 4. This configuration allows the drive motor in this embodiment to have the following driving states:

[0069] First driving state: Only the first clutch 2 is engaged, while the second clutch 3 is disengaged; at this time, after the drive motor starts, the power output by the drive motor can be transmitted to the windshield wiper 5 through the first clutch 2. That is to say, in this first driving state, the drive motor can only drive the windshield wiper 5 to work.

[0070] Second driving state: Only the second clutch 3 is engaged, while the first clutch 2 is disengaged; in this state, after the drive motor starts, the power output by the drive motor can be transmitted to the parking brake 4 through the second clutch 3. That is to say, in this second driving state, the drive motor can only drive the parking brake 4.

[0071] Third driving state: Both the first clutch 2 and the second clutch 3 are engaged. In this state, after the drive motor starts, the power output by the drive motor can be transmitted to the windshield wiper 5 through the first clutch 2, and simultaneously to the parking brake 4 through the second clutch 3. That is to say, in this third driving state, the drive motor can simultaneously drive the windshield wiper 5 and the parking brake 4.

[0072] As described above, in this embodiment of the application, the vehicle uses a drive motor to drive the windshield wiper 5 and / or the parking brake 4. This configuration reduces the number of drive motors used, which in turn helps to save space in the vehicle layout, reduce the weight of the vehicle, and lower the overall vehicle cost.

[0073] In some embodiments, with the windshield wiper 5 connected to the output shaft of the drive motor via the first clutch 2 and the parking brake 4 connected to the output shaft of the drive motor via the second clutch 3, both the first clutch 2 and the second clutch 3 are ratchet clutches. When the output shaft of the drive motor rotates forward, the first clutch 2 is engaged and the second clutch 3 is disengaged; when the output shaft of the drive motor rotates in reverse, the first clutch 2 is disengaged and the second clutch 3 is engaged. Alternatively, when the output shaft of the drive motor rotates in reverse, the first clutch 2 is engaged and the second clutch 3 is disengaged; when the output shaft of the drive motor rotates forward, the first clutch 2 is disengaged and the second clutch 3 is engaged. In this way, when the drive motor starts and rotates in a specific direction, since one of the first clutch 2 and the second clutch 3 is engaged when the motor rotates forward and the other is engaged when the motor rotates in reverse, it is beneficial to achieve precise and independent control of the windshield wiper 5 and the parking brake 4.

[0074] Specifically, when the windshield wipers 5 are needed for normal driving, the drive motor rotates, and the first clutch 2, based on its ratchet characteristics, smoothly transmits power to the wipers 5, causing them to swing at a set frequency and amplitude, effectively clearing rainwater, dust, and other impurities from the windshield, providing the driver with a clear view and ensuring driving safety. At this time, since only the first clutch 2 is active, the power output from the drive motor is not transmitted to the parking brake 4, preventing the parking brake 4 from malfunctioning and interfering with vehicle operation. When the vehicle needs to be parked, the rotation direction of the drive motor is changed through a specific control method. At this time, the second clutch 3 activates, transmitting power to the parking brake 4, causing it to quickly enter the working state and firmly lock the vehicle, preventing it from rolling away.

[0075] Furthermore, as mentioned above, when adjusting the driving state of the drive motor in this embodiment, the vehicle only needs to adjust the rotation direction of the motor, without needing to control the clutch (including the first clutch and the second clutch). This simplifies the control route, reduces the probability of malfunctions, simplifies the control structure, and reduces costs.

[0076] Furthermore, in some embodiments, such as Figure 2 As shown, the ratchet clutch includes an inner ring 301, an outer ring 302, a pawl 304, and an elastic element (not shown in the figure).

[0077] The outer ring 302 of the ratchet clutch is fitted on the outer circumferential surface of the inner ring 301 and can rotate relative to the inner ring 301. One of the inner ring 301 and the outer ring 302 is connected to the output shaft of the drive motor, and the other can form a power output end, that is, the other is connected to the parking brake 4 or the windshield wiper 5. When the ratchet clutch is engaged, the other of the inner ring 301 and the outer ring 302 can transmit the torque output by the drive motor to the parking brake 4 or the windshield wiper 5.

[0078] Furthermore, one of the outer peripheral surface of the inner ring 301 (i.e. the surface of the inner ring 301 facing the outer ring 302) and the inner wall surface of the outer ring 302 (i.e. the surface of the outer ring 302 facing the inner ring 301) has a ratchet tooth 303, and the other is rotatably connected to a pawl 304 arranged between the inner ring 301 and the outer ring 302.

[0079] The elastic element is connected to the pawl 304 and is used to make the automatic end of the pawl 304 abut against the ratchet tooth 303. In this way, under the action of the elastic element and the ratchet tooth 303, the outer ring 302 can only rotate in one direction relative to the inner ring 301, thus giving the ratchet clutch the characteristic of unidirectional power transmission.

[0080] In an exemplary embodiment, the elastic element can be a spring sheet, one end of which is connected to the pawl 304, and the other end is connected to the inner ring 301 or outer ring 302 of the rotatably connected pawl 304. Alternatively, the elastic element can also be a torsion spring, and the two torsion arms of the torsion spring are respectively connected to the pawl 304 and the inner ring 301 or outer ring 302 of the rotatably connected pawl 304.

[0081] Understandably, given that both the first clutch 2 and the second clutch 3 are ratchet clutches, the drive motor can only drive the windshield wiper 5 or the parking brake 4 at a time, and cannot simultaneously drive both the windshield wiper 5 and the parking brake 4. Therefore, the vehicle in this embodiment includes a main controller, which is electrically connected to the drive motor and can control the rotation direction of the drive motor's output shaft.

[0082] Furthermore, in this embodiment, the main controller implements a parking priority principle.

[0083] For ease of description, the following explanation will be based on the following example: when the output shaft of the drive motor rotates clockwise, the first clutch 2 is engaged, and the drive motor drives the windshield wiper 5; when the output shaft of the drive motor rotates counterclockwise, the second clutch 3 is engaged, and the drive motor drives the parking brake 4.

[0084] When the main controller receives a wiper command, it first determines whether a parking command has been received at the same time or whether a parking command is being executed.

[0085] If the main controller does not receive a parking command or is not executing a parking command, the main controller controls the output shaft of the drive motor to rotate clockwise, thereby enabling the drive motor to drive the wiper 5 to work.

[0086] If the main controller receives a parking command, and / or is executing a parking command, the main controller first controls the output shaft of the drive motor to rotate counterclockwise so that the drive motor can drive the parking device 4 to complete the parking action; after parking is completed, the main controller then controls the output shaft of the drive motor to rotate clockwise so that the drive motor can drive the wiper 5 to work.

[0087] In addition, if the master controller receives a parking command while executing wiper commands, the master controller will suspend the execution of wiper commands and prioritize the parking command. Once parking is completed, the wiper commands will resume.

[0088] In this way, the main controller can effectively ensure parking safety by implementing the principle of prioritizing parking.

[0089] It should be understood that the above description is merely an example of the first clutch 2 and the second clutch 3 being ratchet clutches. However, this application is not limited to this. For example, the first clutch 2 and the second clutch 3 can also be roller one-way clutches. When the output shaft of the drive motor rotates forward, the first clutch 2 is engaged and the second clutch 3 is disengaged. When the output shaft of the drive motor rotates in reverse, the first clutch 2 is disengaged and the second clutch 3 is engaged. Alternatively, when the output shaft of the drive motor rotates in reverse, the first clutch 2 is engaged and the second clutch 3 is disengaged. When the output shaft of the drive motor rotates forward, the first clutch 2 is disengaged and the second clutch 3 is engaged. Alternatively, one of the first clutch 2 and the second clutch 3 may be a ratchet clutch, and the other may be a roller-type one-way clutch. When the output shaft of the drive motor rotates forward, the first clutch 2 is engaged and the second clutch 3 is disengaged. When the output shaft of the drive motor rotates in reverse, the first clutch 2 is disengaged and the second clutch 3 is engaged. Alternatively, when the output shaft of the drive motor rotates in reverse, the first clutch 2 is engaged and the second clutch 3 is disengaged. When the output shaft of the drive motor rotates forward, the first clutch 2 is disengaged and the second clutch 3 is engaged.

[0090] Of course, in some other embodiments, in order to enable the windshield wiper 5 and the parking brake 4 to work simultaneously, the first clutch 2 and the second clutch 3 can also be configured as a single-plate friction clutch, a multi-plate friction clutch, etc.

[0091] In some embodiments, the vehicle includes a locking mechanism 6 for enabling the parking brake 4 to remain in a parking brake state.

[0092] Understandably, the parking brake 4 is generally equipped with a return mechanism, which is used to restore the parking brake 4 to the released parking brake state in order to avoid the parking brake 4 affecting the normal driving of the vehicle.

[0093] Based on the above-mentioned return mechanism, a locking mechanism 6 is provided in this embodiment to overcome the influence of the return mechanism on the parking brake 4, so as to ensure that the parking brake 4 can remain in the parking brake state.

[0094] like Figure 3 and Figure 4 As shown, the locking mechanism 6 in this embodiment includes a locking block 601, a locking drive 602, and a locking controller 603. Wherein:

[0095] Locking block 601 is the actuating component in locking mechanism 6 used to implement locking action.

[0096] The locking drive 602 is connected to the locking block 601 and is used to drive the locking block 601 to move.

[0097] The locking controller 603 is a control structure that is electrically connected to the locking drive 602 to control the locking drive 602 to start or stop.

[0098] As can be understood, as described above, in this application, the output end of the second clutch 3 is connected to the parking brake 4, and when the output end of the second clutch 3 rotates, it can drive the parking brake 4 and change the parking brake 4 from a released parking brake state to a parking brake state. Based on this, when the parking brake 4 is in the parking brake state, the output end of the second clutch 3 remains stationary, thus keeping the parking brake 4 in the parking brake state. Based on this, the locking mechanism 6 in this embodiment has a locked state and an unlocked state.

[0099] Furthermore, in the locked state, the locking block 601 is locked in engagement with the output end of the second clutch 3 (this locking engagement can be either abutting or inserting between the locking block 601 and the second clutch 3, etc., and can be adaptively adjusted as needed during specific implementation), thereby preventing the output end of the second clutch 3 from rotating; thus, the parking brake 4 can remain in the parking brake state. In the unlocked state, the locking block 601 disengages from the output end of the second clutch 3. In this way, the parking brake 4 can be restored to the released parking brake state under the action of the return mechanism.

[0100] Based on the second clutch 3 being a ratchet clutch, in some embodiments, the inner ring 301 of the ratchet clutch is connected to the output shaft of the drive motor, and the outer ring 302 of the ratchet clutch is connected to the parking brake 4.

[0101] Furthermore, such as Figure 4 As shown, the outer ring 302 of the ratchet clutch has a plurality of stop protrusions 3022 evenly distributed around its outer circumferential surface. That is, the outer ring 302 includes an outer ring body 3021 and a plurality of stop protrusions 3022, and the plurality of stop protrusions 3022 are evenly distributed around the outer circumferential surface of the outer ring 302. Furthermore, in the locked state of the locking mechanism 6, the locking block 601 is separably locked with at least one stop protrusion 3022. The provision of the stop protrusion 3022 can effectively improve the reliability of the locking engagement between the locking block 601 and the outer ring 302. Furthermore, since the stop protrusions 3022 are evenly distributed around the outer circumference of the ratchet clutch outer ring 302, the locking block 601 can find a suitable stop protrusion 3022 to lock regardless of the angle position of the ratchet clutch, avoiding the locking failure problem caused by angle deviation. This ensures that the parking brake 4 can always be stably maintained in the parking brake state, effectively preventing the vehicle from moving unexpectedly when parked, and greatly improving the safety of vehicle parking.

[0102] In some embodiments, the locking block 601 is made of magnetic material. One end of the locking block 601 is connected to the vehicle body via a rotating connector.

[0103] The rotating connector can be a pin or hinge, or other connector capable of rotatably connecting the locking block to the vehicle body. In an exemplary embodiment, the rotating connector is a pin. One end of the locking block 601 has a first connecting hole that connects to the pin. Two locking block mounting seats are fixed to the vehicle body at intervals, and each of the two locking block mounting seats has a second connecting hole. The locking block 601 is located between the two locking block mounting seats, and the first connecting hole and the second connecting hole are directly opposite each other. The pin passes through the second connecting holes on the two locking block mounting seats and the first connecting hole on the locking block 601, and is press-fitted with the second connecting holes on both locking block mounting seats, and rotatably engaged with the first connecting hole on the locking block 601, thereby achieving a rotatable connection between the locking block 601 and the vehicle body.

[0104] The locking drive 602 includes an electromagnet disposed near the end of the locking block 601 away from the rotating connector; and, in the locked state of the locking mechanism 6, the electromagnet can attract the locking block 601 so that the locking block 601 is separated from the outer ring 302 of the second clutch 3.

[0105] The locking controller 603 is used to control the electromagnet to be energized or de-energized.

[0106] In the above configuration, when the locking controller 603 energizes the electromagnet, the end of the locking block 601 furthest from the rotating connector is attracted by the electromagnet, thereby separating the locking block 601 from the outer ring 302 of the ratchet clutch and putting the locking mechanism 6 in the unlocked state. When the locking controller 603 de-energizes the electromagnet, the end of the locking block 601 furthest from the rotating connector abuts against the outer ring 302 of the ratchet clutch under the action of gravity and locks with the stop protrusion 3022, thereby putting the locking mechanism 6 in the locked state.

[0107] It should be understood that the above is only an exemplary implementation of the locking mechanism 6, and this application is not limited thereto. For example, the locking drive 602 can also be a motor capable of forward and reverse rotation. The output shaft of the motor is connected to the locking block 601. The locking controller 603 controls the locking drive 602 to rotate forward and reverse, so that the end of the locking block 601 away from the output shaft swings, thereby realizing the switching of the locking mechanism 6 between the locked state and the unlocked state.

[0108] Understandably, as mentioned above, the parking brake 4 has a return mechanism inside. Under the action of the return mechanism, in the locked state of the locking mechanism 6, there is a large frictional force between the locking block 601 and the stop protrusion 3022. Based on this, to ensure that the locking mechanism 6 can smoothly change from the locked state to the unlocked state, in some embodiments, the vehicle includes a main controller, which is electrically connected to both the drive motor and the locking controller 603. When the main controller receives a command to release the parking brake, it controls the drive motor to rotate a certain angle (exemplarily, the angle can be in the range of 0.5° to 1°) to release the clamping state between the locking block 601 and the stop protrusion 3022. After the clamping state between the locking block 601 and the stop protrusion 3022 is released, the main controller sends a command to the locking controller 603 to release the locking state. The locking controller 603 controls the locking drive 602 to drive the locking block 601 to move, so that the locking mechanism 6 changes from the locked state to the unlocked state.

[0109] Furthermore, in some embodiments, a detection component is provided for detecting the engagement state between the locking block 601 and the stop protrusion 3022. This detection component is electrically connected to the main controller. Thus, during the aforementioned parking brake release process, after the detection component sends a signal indicating the release of the locking state to the main controller, the main controller then issues a command to the locking controller 603 to release the locking state. This significantly improves the accuracy and reliability of the parking brake release process.

[0110] Specifically, without a detection component, during the process of the drive motor rotating to release the clamping state, the clamping state may not be completely released due to mechanical failure or other unexpected factors. However, if the main controller directly issues an unlocking command at this time, the locking block 601 will forcibly move before it is completely released from the clamping state, which may damage the internal parts of the locking mechanism 6, shorten its service life, or even cause safety hazards. In this embodiment, a detection component is set to monitor the clamping state between the locking block 601 and the stop protrusion 3022 in real time and feed the detected information back to the main controller. The main controller decides whether to issue a command to release the locking state to the locking controller 603 based on this accurate signal. This can avoid operational errors caused by signal misjudgment or delay, thereby greatly improving the accuracy and reliability of the parking brake release process; at the same time, it reduces vehicle maintenance costs and potential risks caused by malfunctions.

[0111] In an exemplary embodiment, the detection component may include a pressure sensor disposed on the locking block 601 and used to detect the pressure between the locking block 601 and the stop protrusion 3022, and to transmit the pressure signal to the main controller, which determines whether the locking block 601 and the stop protrusion 3022 are in a tight state based on the pressure signal.

[0112] In an exemplary embodiment, the detection component may further include a photoelectric sensor, which is used to detect whether there is a gap between the locking block 601 and the stop protrusion 3022, and transmit the detection data to the main controller. The main controller determines whether the locking block 601 and the stop protrusion 3022 are in a tight state based on the detection data.

[0113] In some embodiments, the first clutch 2 is connected to the output shaft of the drive motor via a worm gear structure. In this configuration, the worm gear structure has a self-locking characteristic, effectively preventing the wiper 5 from rotating on its own due to external forces when not in operation, thus ensuring its positional stability. Furthermore, the worm gear structure can serve as a reduction mechanism, achieving a large reduction ratio with fewer parts, which is beneficial for power transmission within a limited space.

[0114] In an exemplary embodiment, the first clutch 2 is a ratchet clutch, and a worm gear is coaxially connected to the output shaft of the drive motor. The outer circumferential surface of the outer ring 302 of the first clutch 2 has a tooth structure that meshes with the worm gear. In this way, integrating the worm gear structure into the output shaft and the first clutch 2 simplifies the structure and reduces costs.

[0115] In some embodiments, the vehicle includes a body, and the body has a windshield and a drive motor mounting bracket; the drive motor mounting bracket is used to mount a drive motor, and the drive motor mounting bracket is disposed near the lower edge of the windshield.

[0116] In this configuration, the drive motor is installed closer to the wiper 5, which shortens the transmission distance between the wiper body 501 and the drive motor, thereby improving transmission efficiency.

[0117] Understandably, the parking action of the parking brake 4 is an action that can be completed in a short time, while the windshield wiper 5, as a key component ensuring clear driving visibility, typically needs to operate continuously for extended periods. This places higher demands on the stability and durability of the drive system. In this embodiment, by mounting the drive motor closer to the windshield wiper 5, not only is the power transmission path shortened and mechanical losses reduced, but vibration and noise from transmission components are also effectively reduced. Simultaneously, the response speed and wiping accuracy of the windshield wiper 5 during prolonged continuous operation are improved, thereby significantly enhancing the overall reliability of the wiper system.

[0118] Furthermore, compared to the windshield wiper 5, the parking brake 4 can use a pull rope as a transmission structure. Based on this, in this embodiment, the installation position of the drive motor is set closer to the windshield wiper 5, which is more conducive to the arrangement of the transmission structure.
