[0052] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0053] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present disclosure belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0054] One or more embodiments of the present application provide a method for executing a park start, wherein the park start refers to switching a vehicle from a parked state to a driving state. The vehicle's braking device includes a plurality of brake discs 1. The brake discs 1 are generally used in disc brakes. The brake discs 1 rotate synchronously with the wheels, and friction elements (such as brake pads 5) clamp the brake discs 1 from both sides to produce a braking effect. Currently, friction elements have various structural forms, such as caliper disc type or full disc type, etc. Here, the brake disc 1 can be applied to various different disc brake structural forms.

[0055] In the embodiment of the present application, each brake disc 1 is provided with a heating mechanism. Here, the heating mechanism is described with reference to the heating mechanism described in other embodiments of the present application. Of course, the heating mechanism may also adopt other existing mature structures.

[0056] This embodiment provides a method for executing a parking start, such as Figure 1 As shown, the method includes:

[0057] S1 , obtaining gap data between each brake disc 1 and the corresponding brake pad 5 in a vehicle braking device, and determining abnormal gap data among a plurality of gap data.

[0058] S2, obtaining ambient temperature information, and determining a temperature adjustment mode according to the ambient temperature information.

[0059] S3 , sending a temperature adjustment signal corresponding to the temperature adjustment mode to the heating mechanism, so that the heating mechanism heats the brake disc 1 .

[0060] From the above description, it can be seen that the execution method of parking start provided in this embodiment determines whether the brake disc 1 and the brake pad 5 are in an abnormal state by obtaining the gap data between the brake disc 1 and the brake pad 5, and determines whether the abnormality is a component abnormality or an abnormality caused by low-temperature freezing by obtaining the ambient temperature information. The temperature adjustment mode is determined according to the ambient temperature information, and a temperature adjustment signal is sent to the heating mechanism. The heating mechanism can heat the brake disc 1, thereby thawing the frozen brake disc 1 and eliminating the abnormal gap, which is conducive to the vehicle quickly switching from the parking state to the driving state, and can reduce manual intervention and save time.

[0061] It should be noted that the execution method mentioned in this embodiment is carried out under the premise that the switching from the parking state to the driving state fails. In some scenarios, the execution method described in the embodiment is executed under the premise that the driver fails to release the handbrake.

[0062] In some embodiments, in step S1, determining abnormal gap data from a plurality of gap data includes:

[0063] S1a, comparing each acquired gap data with a target threshold value, and when a gap data is smaller than the target threshold value, determining that the gap data is abnormal gap data.

[0064] In some embodiments, in step S1a, the target threshold can be set to 3mm. This means that when the gap between the brake disc 1 and the brake pad 5 is greater than or equal to 3mm, the gap is considered normal and meets the parking brake release condition. When the gap between the brake disc 1 and the brake pad 5 is less than 3mm, the gap is considered abnormal, indicating that the gap between the brake disc 1 and the brake pad 5 is too small and a foreign object is stuck. The target threshold should be flexibly set based on various factors, such as the type and specifications of the actual disc brake. The target threshold setting parameters in this embodiment are provided for illustrative purposes only.

[0065] In some embodiments, between step S1 and step S2, that is, after determining the abnormal gap data and before obtaining the ambient temperature information, the following steps are further included:

[0066] S1b, perform multiple handbrake release actions at intervals.

[0067] S1c, in response to the failure of releasing the parking brake, a stuck state warning signal is issued.

[0068] Here, as an exemplary illustration, Figure 2As shown, the parking brake release cycle is every 10 seconds, with a maximum of 5 attempts. If the parking brake release fails after 5 attempts, a stuck state warning message will be displayed on the instrument panel or center console, reminding the driver to exit the vehicle and investigate the anomaly. This step improves fault tolerance and facilitates the attempted recovery of the vehicle's stuck state, thereby avoiding continuous alarms due to factors such as electronic parking brake jamming or false alarm activation. As an alternative embodiment, the parking brake release cycle and number of times can also be set to other values.

[0069] In the above embodiment, when the vehicle is in a stuck state, it includes the following scenarios: there are solid foreign objects such as gravel stuck between the brake disc 1 and the brake pad 5; ice is stuck between the brake disc 1 and the brake pad 5 due to accumulated water, rain, snow, etc.; or the brake disc 1 and the brake pad 5 are stuck and the handbrake cannot be released due to a failure of the braking device itself.

[0070] Regardless of the scenario, the jam warning signal prompts the driver to exit the vehicle and inspect the situation. If the brake disc 1 and brake pad 5 are stuck due to gravel or foreign matter, the driver can manually remove the gravel jam. If the brake disc 1 and brake pad 5 are stuck due to ice, the system detects ambient temperature and sends a temperature adjustment signal to the heating mechanism, causing it to thaw the brake disc 1 and remove the ice. If the brake disc 1 remains stuck after heating and the parking brake cannot be released, the brake system itself is suspected to be faulty. Drivers should refrain from operating the brake system and call a dealer for technical support.

[0071] In some embodiments, the clearance data obtained is generally the clearance data between the brake disc 1 and the brake pad 5 corresponding to each wheel. When it is determined that there is abnormal clearance data, the stuck state warning signal can show which specific wheel is in the stuck state, so that the driver can locate the fault position and perform subsequent maintenance work.

[0072] In some embodiments, the ambient temperature information acquired in step S2 may be the surface temperature of the brake disc 1, which is acquired by a temperature sensor disposed on the surface of the brake disc 1. Alternatively, the temperature information may be the temperature of the vehicle's environment, which is acquired by a temperature sensor disposed on the vehicle. The ambient temperature information may be acquired in real time or periodically.

[0073] In some embodiments, it is possible to first determine whether the acquired ambient temperature information is greater than 0°C. When it is greater than 0°C, the stuck state between the brake disc 1 and the brake pad 5 due to ice formation is eliminated; that is, only when the ambient temperature information is less than 0°C will the subsequent steps of determining the temperature adjustment mode be executed.

[0074] As an example, Figure 2 As shown, the driver starts the engine and tries to release the handbrake. When releasing the handbrake, the gap detection module 6 of the vehicle obtains the gap data L between the brake disc and the brake pad. When the obtained gap data L are all greater than 3mm, the handbrake release condition is met and the handbrake is successfully released. When any of the gap data L is less than or equal to 3mm, the handbrake release action is performed at intervals of 10s for 5 times. If all 5 actions are unsuccessful, it indicates that the vehicle is stuck.

[0075] Subsequently, the wheel location of the abnormal clearance data is determined. Next, the temperature sensing module acquires ambient temperature information T. When ambient temperature information T is greater than 0°C, the vehicle dashboard or other device issues a jam warning signal, prompting the driver to exit the vehicle and inspect and resolve the jammed object. If the jam is resolved successfully, the parking brake is released. If the jam cannot be resolved, the driver can call the 4S dealership for technical support. If the jam still cannot be resolved, the 4S dealership can be called for on-site assistance. When ambient temperature information T is less than 0°C, the subsequent steps of the present method are continued, namely, determining a temperature adjustment mode and sending a corresponding temperature adjustment signal to the heating mechanism.

[0076] Specifically, in step S2, it includes:

[0077] S2a, determining a preset threshold interval according to the ambient temperature information, and determining a corresponding temperature adjustment mode according to the preset threshold interval, wherein there are multiple preset threshold intervals, and each preset threshold interval corresponds to a different temperature adjustment mode.

[0078] In step S2a, as an exemplary illustration, Figure 3 As shown, the preset threshold range can be divided into the following four ranges:

[0079] The first preset threshold range: -5℃~0℃;

[0080] The second preset threshold range: -10℃~-5℃;

[0081] The third preset threshold range: -20℃~-10℃;

[0082] Fourth preset threshold range: below -20°C.

[0083] Among the above four preset threshold intervals, the first preset threshold interval corresponds to the first temperature adjustment mode, the second preset threshold interval corresponds to the second temperature adjustment mode, the third preset threshold interval corresponds to the third temperature adjustment mode, and the fourth preset threshold interval corresponds to the fourth temperature adjustment mode.

[0084] Furthermore, when the acquired ambient temperature information is within the first preset threshold interval, it is determined as the first temperature adjustment mode, and a temperature adjustment signal corresponding to the first temperature adjustment mode is sent to the heating mechanism, so that the heating mechanism heats the brake disc 1; similarly, when the acquired ambient temperature information is within the second preset threshold interval, it is determined as the second temperature adjustment mode, and a temperature adjustment signal corresponding to the second temperature adjustment mode is sent to the heating mechanism, so that the heating mechanism heats the brake disc 1; when the acquired ambient temperature information is within the third preset threshold interval, it is determined as the third temperature adjustment mode, and a temperature adjustment signal corresponding to the third temperature adjustment mode is sent to the heating mechanism, so that the heating mechanism heats the brake disc 1; when the acquired ambient temperature information is within the fourth preset threshold interval, it is determined as the fourth temperature adjustment mode, and a temperature adjustment signal corresponding to the fourth temperature adjustment mode is sent to the heating mechanism, so that the heating mechanism heats the brake disc 1.

[0085] Through the above settings, the corresponding temperature adjustment mode can be selected according to the actual ambient temperature, thereby avoiding the problem of waste caused by excessive output power or long waiting time due to insufficient output power while ensuring the heating effect of the brake disc 1; at the same time, the processing of the acquired ambient temperature information is more reasonable, and the allocation path is clearer, which is conducive to rapid response and improved processing speed.

[0086] It should be noted that the exemplary description in this embodiment sets four preset threshold intervals. In other embodiments, the preset threshold intervals can be flexibly set according to the actual usage scenario. For example, two preset threshold intervals can be set to -10℃~0℃ and above -10℃; the temperature adjustment mode should also be changed accordingly to the preset threshold intervals.

[0087] Here, in the aforementioned step S3, the heating mechanism includes a ventilation mechanism and a liquid circulation mechanism, the ventilation mechanism includes a first regulating valve 32, the liquid circulation mechanism includes a second regulating valve 48, and the temperature adjustment signal includes the opening data of the first regulating valve 32, the opening data of the second regulating valve 48, the ventilation heating power, and the liquid circulation heating power; step S3 also includes:

[0088] The sending of the temperature adjustment signal corresponding to the temperature adjustment mode to the heating mechanism so that the heating mechanism heats the brake disc includes:

[0089] sending a temperature adjustment signal corresponding to the temperature adjustment mode to the ventilation mechanism, so that the ventilation mechanism supplies hot air to the brake disc according to the ventilation heating power corresponding to the temperature adjustment mode, and causes the first regulating valve 32 to adjust its opening according to the first regulating valve 32 opening data corresponding to the temperature adjustment mode; and\or,

[0090] A temperature adjustment signal corresponding to the temperature adjustment mode is sent to the liquid circulation mechanism, so that the liquid circulation mechanism supplies heating liquid to the brake disc according to the liquid circulation heating power corresponding to the temperature adjustment mode, and the second regulating valve 48 adjusts its opening according to the second regulating valve 48 opening data corresponding to the temperature adjustment mode.

[0091] In the above steps, the ventilation mechanism and the liquid circulation mechanism can heat the brake disc 1 at the same time, or one of them can be selected to heat the brake disc 1. Figure 3 As shown, the temperature adjustment modes of the ventilation mechanism and the liquid circulation mechanism include the following scenarios:

[0092] (1) When it is determined that the ambient temperature information is within the first preset threshold range (-5°C to 0°C), only the ventilation mechanism is turned on, and the opening of the first regulating valve 32 is adjusted to 50% for a duration of 1 minute;

[0093] (2) When it is determined that the ambient temperature information is within the second preset threshold range (-10°C to -5°C), the ventilation mechanism and the liquid circulation mechanism are turned on, and the openings of the first regulating valve 32 and the second regulating valve 48 are both adjusted to 50% for a duration of 1 minute;

[0094] (3) When it is determined that the ambient temperature information is within the third preset threshold range (-20°C to -10°C), the ventilation mechanism and the liquid circulation mechanism are turned on, the opening of the first regulating valve 32 is adjusted to 50%, and the opening of the second regulating valve 48 is adjusted to 100%, and the duration is 1 minute;

[0095] (4) When it is determined that the ambient temperature information is within the fourth preset threshold range (below -20°C), the ventilation mechanism and the liquid circulation mechanism are turned on, and the openings of the first regulating valve 32 and the second regulating valve 48 are both adjusted to 100% for a duration of 1 minute.

[0096] In the above embodiment, the setting data of the opening percentage of the first regulating valve 32 and the second regulating valve 48 are only used as examples, and their openings can also be set to other values; the duration can be flexibly adjusted according to various factors such as ambient temperature information and output power.

[0097] In the above embodiment, the temperature adjustment signal is used to control the temperature adjustment mode of the ventilation mechanism only by adjusting the first regulating valve 32, and to control the temperature adjustment mode of the liquid circulation mechanism by adjusting the second regulating valve 48. The opening sizes of the first regulating valve 32 and the second regulating valve 48 correspond to the sizes of the heating rates of the brake disc. The larger the opening of the first regulating valve 32, the greater the air output of the ventilation mechanism, and the faster the heating rate of the brake disc by the ventilation mechanism; the larger the opening of the second regulating valve 48, the greater the liquid output of the liquid circulation mechanism, and the faster the heating rate of the brake disc by the liquid circulation mechanism.

[0098] Here, the output power can also be adjusted by the aforementioned heating power. For example, when the opening of the first regulating valve 32 is fixed, the air-conditioning hot air power or hot air temperature of the air-conditioning system can also be directly adjusted, thereby realizing the adjustment of the ventilation mechanism by the temperature adjustment signal; when the opening of the second regulating valve 48 is fixed, the liquid circulation power of the water circuit of the entire vehicle structure, that is, the hot water temperature or water pressure in the water circuit, can be directly adjusted to realize the adjustment of the output power of the liquid circulation mechanism by the temperature adjustment signal.

[0099] In some embodiments, the temperature control signal can simultaneously adjust the opening of the first control valve 32 and the heating power of the ventilation mechanism to adjust the temperature control mode of the ventilation mechanism. For example, opening the first control valve 32 to 50% and increasing the heating power of the ventilation mechanism can heat the brake disc more quickly than simply opening the first control valve 32 to 50%. Similarly, the temperature control signal can also simultaneously adjust the opening of the second control valve 48 and the heating power of the fluid circulation mechanism.

[0100] In some embodiments, the temperature adjustment signal can adjust the heating power of the ventilation mechanism, the first regulating valve 32, the heating power of the circulation structure and the second regulating valve 48. The adjustment form can be flexibly set with reference to factors such as the actual ambient temperature and the vehicle usage status. This is only illustrated by example in this embodiment.

[0101] In the above embodiment, only one method of controlling the heating mechanism is exemplified. As an alternative implementation method, when the ambient temperature information is in a relatively mild first preset threshold range, the liquid circulation mechanism may be turned on first without turning on the ventilation mechanism; when the ambient temperature information is in a second preset threshold range, the liquid circulation mechanism may not be turned on, but the opening of the first regulating valve 32 may be opened to 100% to achieve an increase in the heating rate, etc. For different preset threshold ranges, the temperature adjustment modes of the ventilation mechanism and the liquid circulation mechanism may be flexibly set, and no absolute limitation is made in this embodiment.

[0102] In some embodiments, when the ambient temperature information is within one of the preset threshold intervals, after the temperature adjustment signal is sent to heat the brake disc 1, the gap between the brake disc 1 and the brake pad 5 can continue to be detected. If there is still abnormal gap data, the heating rate can be increased to continue heating the brake disc 1. The method of increasing the heating rate can refer to the above-mentioned method; when the heating rate of the ventilation mechanism and the liquid circulation mechanism is the maximum and it is detected that the vehicle still has abnormal gap data and is in a stuck state, there may be a brake device failure. A reminder can be issued to avoid the driver's operation, and technical support can be sought by calling the 4S shop in the future.

[0103] In some embodiments, after step S3, the method further includes:

[0104] S3a, obtaining clearance data between each brake disc 1 and the corresponding brake pad 5 in the vehicle braking device.

[0105] S3b: In response to each clearance data being greater than the target threshold, executing a parking brake release action.

[0106] S3c: In response to any gap data being smaller than a target threshold, a stuck state warning signal is issued.

[0107] In the above steps, the target threshold value can be exemplified as the aforementioned 3 mm; the gap detection module detects and obtains the gap data between each brake disc 1 and the brake pad 5 in real time. After step S3, the ice on the brake disc 1 is heated and thawed by the heating mechanism, and the gap data is greater than the target threshold value, and the parking brake can be successfully released; when any gap data is still less than the target threshold value, that is, there is still abnormal gap data, the stuck state warning signal continues to be issued, so that the driver can seek help from the 4S store or road rescue in time.

[0108] In addition, the present application also provides a brake disc and a heating mechanism for the brake disc, wherein the heating mechanism includes a ventilation mechanism and a liquid circulation mechanism for heating the brake disc, and the aforementioned parking start execution method can be executed based on the structure of the brake disc and the heating mechanism.

[0109] In some embodiments, as Figure 5 As shown, the brake disc 1 has a cavity 12 inside, and the brake disc 1 has a through hole for connecting to the drive shaft 2. The through hole corresponds to the inner wall surface of the drive shaft 2 and is provided with a liquid inlet 13 and a liquid outlet 14 connected to the cavity 12.

[0110] like Figure 4 and Figure 6As shown, the ventilation mechanism is configured to supply air toward at least one air hole 11 on the brake disc 1; the drive shaft 2 passes through the through hole and is connected to the brake disc 1; the liquid circulation mechanism is sleeved on the drive shaft 2, and the drive shaft 2 is provided with a first channel 21 and a second channel 22 at one end of which are respectively connected to the liquid circulation mechanism, the other end of the first channel 21 is connected to the liquid inlet 13, and the other end of the second channel 22 is connected to the liquid outlet 14.

[0111] Here, the ventilation mechanism and the liquid circulation mechanism are provided to not only send hot air or heating liquid to the brake disc 1 for heating and thawing, but also to send cold air or cooling liquid to the brake disc 1 in a high temperature environment for heat dissipation. In this embodiment, the heating work of the brake disc 1 is mainly explained with reference to the ventilation mechanism and the liquid circulation mechanism.

[0112] In some embodiments, the ventilation mechanism includes an air conditioning system for supplying air and a housing 3 connected to the air conditioning system. Housing 3 is provided to partially cover the surface of brake disc 1. The air conditioning system can share the same equipment as the vehicle's internal air conditioning system. External piping from the air conditioning system connects to housing 3 to deliver air to brake disc 1.

[0113] Furthermore, if Figure 6 As shown, the aforementioned shell 3 is a fan-shaped shell 3, and the shell 3 is provided with a connection port 31 for connecting to the external pipeline of the air-conditioning system. The diameter of the connection port 31 is smaller than the coverage area of the fan-shaped shell 3. When the air-conditioning system supplies air through the connection port 31, since the brake disc 1 rotates synchronously with the wheel, the air holes 11 of the brake disc 1 will pass through the coverage area of the shell 3 corresponding to the brake disc 1 in sequence. Under the external pressure, the air volume can blow air to the entire coverage area in the fan-shaped shell 3, so that the air of the air-conditioning system can pass through the air holes 11 located in the coverage area.

[0114] As an alternative embodiment, the shell 3 can also be set to other forms, such as rectangular or circular, but the coverage area of the shell 3 should be at least larger than the diameter of any air hole 11 on the brake disc 1 to ensure the air supply effect of the ventilation mechanism on the brake disc 1.

[0115] In some embodiments, the air volume of the air-conditioning system is pressurized by a gas booster pump and then delivered to the housing 3. The air-conditioning system and the gas booster pump are connected by a first regulating valve 32. The first regulating valve 32 is an air valve with adjustable opening. Here, by setting the air valve, the air supply size of the ventilation mechanism to the brake disc 1 can be flexibly adjusted, that is, the heating rate of the ventilation mechanism to the brake disc can be adjusted, which is conducive to the brake disc 1 to adapt to different working environments.

[0116] In some embodiments, as Figure 7As shown, the drive shaft 2 is used to drive the wheel to rotate. The wheel is coaxially connected to the brake disc 1. The brake disc 1 is fixed to the wheel and rotates synchronously with the wheel. The drive shaft 2 and the brake disc 1 can be fixedly connected by a key or bolt. In addition to the above connection method, the drive shaft 2 and the brake disc 1 can also be connected by other existing connection methods.

[0117] On this basis, two first channels 21 and second channels 22 that are not connected to each other are provided inside the drive shaft 2. The first channel 21 and the second channel 22 are extended along the axis of the drive shaft 2. When the drive shaft 2 is fixedly connected to the brake disc 1, the end of the first channel 21 close to the brake disc 1 is connected to the liquid inlet 13 of the brake disc 1, and the end of the second channel 22 close to the brake disc 1 is connected to the liquid outlet 14 of the brake disc 1.

[0118] It should be noted that to reduce the impact of channel configuration on the strength of the drive shaft 2, the first channel 21 and the second channel 22 can be strip-shaped channels. Since the liquid inlet 13 and the liquid outlet 14 are arranged opposite each other on the perforation of the brake disc 1, the first channel 21 and the second channel 22 can also be arranged opposite each other on the drive shaft 2. As an alternative embodiment, the first channel 21 and the second channel 22 can also be configured in other forms, such as a sector-shaped channel cross-section extending along the curved surface of the drive shaft 2.

[0119] In some embodiments, as Figures 7 to 9 As shown, the aforementioned liquid circulation mechanism includes a liquid inlet pipe 41, a liquid outlet pipe 42 and a connecting portion, wherein the liquid inlet pipe 41 and the liquid outlet pipe 42 are respectively connected to the water channel of the entire vehicle structure. The water channel of the entire vehicle structure can adopt an existing mature water channel connection method, and there is no absolute limitation on this in this embodiment.

[0120] Here, it should be noted that the liquid circulation mechanism can be used to heat or cool the brake disc 1. Therefore, the following scenarios may exist: the liquid inlet pipe 41 takes in coolant, and the liquid outlet pipe 42 discharges hot liquid carrying the heat of the brake disc 1; the liquid inlet pipe 41 takes in hot liquid, and the liquid outlet pipe 42 discharges cold liquid after the heat is dissipated.

[0121] Furthermore, the liquid in the water channel in the vehicle structure is pressurized by the pressure pump and enters the liquid inlet pipe 41. The water channel and the pressure pump are connected by a second regulating valve 48. The second regulating valve 48 is a liquid valve with adjustable opening. By setting the second regulating valve 48, the speed of liquid delivery from the water channel to the brake disc 1 can be flexibly adjusted, which helps the brake disc 1 adapt to different working environments.

[0122] Here, if Figure 10 As shown, the working states of the ventilation mechanism and the liquid circulation mechanism include the following scenarios:

[0123] (1) The first regulating valve 32 is opened, the second regulating valve 48 is closed, and the ventilation mechanism sends cold air to the brake disc 1 (ABC);

[0124] (2) The first regulating valve 32 is opened, the second regulating valve 48 is closed, and the ventilation mechanism sends hot air (DBC) to the brake disc 1;

[0125] (3) The first regulating valve 32 is closed, the second regulating valve 48 is opened, and the liquid circulation mechanism sends coolant (EFG) to the brake disc 1;

[0126] (4) The first regulating valve 32 is closed, the second regulating valve 48 is opened, and the fluid circulation mechanism sends heating fluid (HFG) to the brake disc 1 .

[0127] In some embodiments, the ventilation mechanism and the liquid circulation mechanism can be used separately or in combination at the same time, and the driver can flexibly choose according to the actual driving scenario; the first regulating valve and the second regulating valve can adopt the existing mature three-way valve.

[0128] In some embodiments, as Figure 9 As shown, the connecting portion is rotatably connected to the drive shaft 2 by a sealing sleeve, and a first annular cavity 43 and a second annular cavity 44 are formed and separated between the connecting portion and the drive shaft 2, wherein the liquid inlet pipe 41 is connected to the first channel 21 through the first annular cavity 43, and the liquid outlet pipe 42 is connected to the second channel 22 through the second annular cavity 44.

[0129] In the above embodiment, the connecting portion includes a first annular portion 45 fixedly connected to the drive shaft 2 , and a second annular portion 46 sleeved on the first annular portion 45 , and the second annular portion 46 is rotatably connected to the first annular portion 45 .

[0130] like Figures 7 to 9 As shown, the first annular portion 45 is provided with an opening for making way for the first channel 21 and the second channel 22. The first annular portion 45 is fixedly connected to the drive shaft 2 by screwing or other means. Along the axial direction of the drive shaft 2, the first annular portion 45 and the second annular portion 46 are sequentially spaced with a first seal 50, a second seal 51 and a third seal 52, wherein the first annular cavity 43 is formed between the first seal 50 and the second seal 51, and the second annular cavity 44 is formed between the second seal 51 and the third seal 52. Thus, the first annular portion 45, the second annular portion 46 and part of the surface of the drive shaft 2 jointly form the aforementioned first annular cavity 43 and the second annular cavity 44 to avoid affecting the normal liquid circulation channel.

[0131] Here, the provision of seals can further enhance the sealing properties of each annular cavity, thereby preventing liquid leakage that could affect performance. The first seal 50, the second seal 51, and the third seal 52 can be provided between the first annular portion 45 and the second annular portion 46 in the form of hydraulic seals. As an alternative embodiment, a greater number of seals can be provided between the first annular portion 45 and the second annular portion 46, as long as the first annular cavity 43 and the second annular cavity 44 are separated from each other.

[0132] In some embodiments, the first annular portion 45 and the second annular portion 46 can be connected by a snap-fit connection, wherein a mounting cavity is further formed between the first annular portion 45 and the second annular portion 46. A limiting step is provided on the first annular portion 45 or the second annular portion 46. The mounting cavity is the space formed by the limiting step after the first annular portion 45 and the second annular portion 46 are connected. The mounting cavity is filled with a plurality of balls 47. This arrangement can reduce the rotational friction of the second annular portion 46 relative to the first annular portion 45, making the relative movement between the two smoother. As an alternative embodiment, a mounting cavity can be provided at each end of the first annular portion 45 and the second annular portion 46, and each mounting cavity can be filled with balls 47 to further enhance the smoothness.

[0133] In addition, the present application also provides a braking device, such as Figure 11 As shown, the execution method of the parking start as described in any of the above embodiments includes:

[0134] a gap detection module 6 configured to obtain gap data between each brake disc 1 and the corresponding brake pad 5 in the vehicle brake device, and determine abnormal gap data among the plurality of gap data;

[0135] The temperature sensing module 7 is configured to obtain ambient temperature information and determine a temperature adjustment mode according to the ambient temperature information;

[0136] The signal sending module 8 is configured to send a temperature adjustment signal corresponding to the temperature adjustment mode to the heating mechanism, so that the heating mechanism heats the brake disc 1 .

[0137] For the convenience of description, the above devices are described as being divided into various modules according to their functions. Of course, when implementing this application, the functions of each module can be implemented in the same or multiple software and / or hardware.

[0138] In some embodiments, the gap detection module 6 can use existing mature detection components; the temperature sensing module 7 preferably detects the ambient temperature of the vehicle. As an alternative embodiment, the temperature sensing module 7 can also detect the surface temperature of the brake disc 1.

[0139] In some embodiments, the gap detection module 6, the temperature sensing module 7 and the signal sending module 8 are electrically connected. After the gap detection module 6 detects each gap data, it compares the gap data with the aforementioned target threshold value one by one, and determines the abnormal gap data based on the comparison result; after the temperature sensing module 7 obtains the ambient temperature information, it maps the ambient temperature information to the corresponding preset threshold interval to determine the corresponding temperature adjustment mode according to the corresponding preset threshold interval; the signal sending module 8 sends the corresponding temperature adjustment signal according to the corresponding temperature adjustment mode, thereby adjusting the output power of the heating mechanism for heating the brake disc 1.

[0140] Here, the target threshold can be set to 3mm. That is, when the gap between the brake disc 1 and the brake pad 5 is greater than or equal to 3mm, the gap is considered normal and meets the parking brake release condition. When the gap between the brake disc 1 and the brake pad 5 is less than 3mm, the gap is considered abnormal, indicating that the gap between the brake disc 1 and the brake pad 5 is too small and a foreign object is stuck. The target threshold should be flexibly set based on various factors such as the type and specifications of the actual disc brake. The target threshold setting parameters in this embodiment are merely illustrative.

[0141] In the above embodiment, the possible ambient temperatures can be divided into four preset threshold intervals, for example: first preset threshold interval: -5°C to 0°C;

[0142] The second preset threshold range: -10℃~-5℃;

[0143] The third preset threshold range: -20℃~-10℃;

[0144] Fourth preset threshold range: above -20°C.

[0145] Among the above four preset threshold intervals, the first preset threshold interval corresponds to the first temperature adjustment mode, the second preset threshold interval corresponds to the second temperature adjustment mode, the third preset threshold interval corresponds to the third temperature adjustment mode, and the fourth preset threshold interval corresponds to the fourth temperature adjustment mode.

[0146] Furthermore, when the acquired ambient temperature information is within the first preset threshold interval, it is determined as the first temperature adjustment mode, and a temperature adjustment signal corresponding to the first temperature adjustment mode is sent to the heating mechanism, so that the heating mechanism heats the brake disc 1; similarly, when the acquired ambient temperature information is within the second preset threshold interval, it is determined as the second temperature adjustment mode, and a temperature adjustment signal corresponding to the second temperature adjustment mode is sent to the heating mechanism, so that the heating mechanism heats the brake disc 1; when the acquired ambient temperature information is within the third preset threshold interval, it is determined as the third temperature adjustment mode, and a temperature adjustment signal corresponding to the third temperature adjustment mode is sent to the heating mechanism, so that the heating mechanism heats the brake disc 1; when the acquired ambient temperature information is within the fourth preset threshold interval, it is determined as the fourth temperature adjustment mode, and a temperature adjustment signal corresponding to the fourth temperature adjustment mode is sent to the heating mechanism, so that the heating mechanism heats the brake disc 1.

[0147] The exemplary steps are as follows: (1) when it is determined that the ambient temperature information is within the first preset threshold range (-5°C to 0°C), the first temperature adjustment mode is: only the ventilation mechanism is turned on, and the opening of the first regulating valve 32 is adjusted to 50% for a duration of 1 minute;

[0148] (2) When it is determined that the ambient temperature information is within the second preset threshold range (-10°C to -5°C), the second temperature adjustment mode is: the ventilation mechanism and the liquid circulation mechanism are turned on, and the openings of the first regulating valve 32 and the second regulating valve 48 are both adjusted to 50%, and the duration is 1 minute;

[0149] (3) When it is determined that the ambient temperature information is within the third preset threshold range (-20°C to -10°C), the third temperature adjustment mode is: the ventilation mechanism and the liquid circulation mechanism are turned on, the opening of the first regulating valve 32 is 50%, and the opening of the second regulating valve 48 is adjusted to 100%, and the duration is 1 minute;

[0150] (4) When it is determined that the ambient temperature information is within the fourth preset threshold range (below -20°C), the fourth temperature adjustment mode is: the ventilation mechanism and the liquid circulation mechanism are turned on, and the openings of the first regulating valve 32 and the second regulating valve 48 are both adjusted to 100%, and the duration is 1 minute.

[0151] It should be noted that the exemplary description in this embodiment sets four preset threshold intervals. In other embodiments, the preset threshold intervals can be flexibly set according to the actual usage scenario. For example, two preset threshold intervals can be set to -10℃~0℃ and above -10℃; the temperature adjustment mode should also be changed accordingly to the preset threshold intervals.
