Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to an electromechanical braking device with a mounting surface mating with a wire and a vehicle. Background Technology

[0002] Electro-mechanical brakes (EMBs) use a combination of an electric motor and a mechanical transmission mechanism to drive the brake. EMBs are characterized by their simple structure, rapid response, smooth load transmission, and lack of hydraulic lines, resulting in high transmission efficiency. EMBs can improve vehicle safety, handling, and comfort.

[0003] Electromechanical braking devices include circuit components for auxiliary control, which transmit signals via signal transmission lines. Because the internal mechanical transmission structure of electromechanical braking devices is relatively complex and the internal space is narrow, it is not conducive to the layout of signal transmission lines within the device. Summary of the Invention

[0004] This application provides an electromechanical braking device with wiring exiting through a mating surface and a vehicle. The wiring exits through the mating gap between the mounting surfaces of the housing in the electromechanical braking device, facilitating the laying of signal transmission lines and reducing the overall size of the electromechanical braking device. Specifically, this application includes the following solutions:

[0005] In a first aspect, this application provides an electromechanical braking device with a mounting surface mating with a lead wire. The electromechanical braking device includes a driver housing and a brake housing. The driver housing accommodates a driver transmission assembly, and the brake housing accommodates a brake transmission assembly. The brake transmission assembly drives at least one friction pad. The driver housing and the brake housing each include a mounting surface, and the two mounting surfaces are fixedly connected to each other, wherein:

[0006] Each mounting surface includes a through-hole for circumventing a drive connector for connecting the drive assembly of the driver to the drive assembly of the brake.

[0007] At least one mounting surface includes at least one recess for accommodating at least one signal transmission line for electrically connecting at least one circuit assembly housed in the housing of the driver or the housing of the brake.

[0008] In this application's electromechanical braking device, the actuator housing and the brake housing are fixedly connected. A groove formed by the mating of two mounting surfaces avoids the signal transmission line, allowing the circuit components housed within one housing to extend the signal transmission line through the gap between the two mounting surfaces. The signal transmission line's extension distance inside the electromechanical braking device's housing is relatively short, which facilitates the arrangement of internal transmission components and reduces the overall size of the device. Simultaneously, the signal transmission line outside the housing is easy to arrange.

[0009] In one implementation, the groove extends in a direction parallel to the mounting surface. Along the extension direction of the groove, the groove includes an inlet end near the through hole and an outlet end away from the through hole, wherein:

[0010] The input terminal connects to the inside of the driver housing or the brake housing, and the signal transmission line extends into the groove through the input terminal;

[0011] The outgoing terminal is located at the edge of the mounting surface, and the signal transmission line extends out of the mounting surface through the outgoing terminal.

[0012] In this implementation, the position of the signal transmission line in the housing is relatively close to the center of the mounting surface, which is beneficial to the sealing and protection of the inside of the housing.

[0013] In one implementation, the groove extends along a straight line parallel to the mounting surface, and the extension line of the line connecting the outlet end and the inlet end of the groove passes through the center of the through hole.

[0014] In this implementation, the signal transmission line has a relatively short extension path and is easy to manufacture the groove.

[0015] In one implementation, the electromechanical braking device includes a seal that fills the gap between the signal transmission line and the input terminal to seal the housing of the driver or the housing of the brake.

[0016] In this implementation, the seal can provide a sealing and protective effect on the housing.

[0017] In one implementation, there are two grooves, which are symmetrically distributed vertically with respect to the center of the through hole, wherein:

[0018] When the electromechanical braking device is used to brake the left wheel of a vehicle, the signal transmission line extends out of the mounting surface through a groove;

[0019] When the electromechanical braking device is used to brake the right wheel of a vehicle, the signal transmission line extends out of the mounting surface through another groove.

[0020] In this implementation, the two grooves are symmetrically arranged, which can improve the compatibility and interchangeability of the electromechanical braking device, so that the electromechanical braking device can be adapted to both the left and right wheels of the vehicle.

[0021] In one implementation, the housing of the actuator and the housing of the brake are fixedly connected by a pair of bolts, wherein:

[0022] A pair of bolts are radially symmetrically distributed with respect to the center of the through hole;

[0023] Along the circumference of the through hole, one of the bolts in a pair is located between the two grooves.

[0024] In this implementation, the two housings are fixedly connected by a pair of bolts, and the arrangement of the pair of bolts is roughly in the vertical direction, which can compress the horizontal dimension of the electromechanical braking device and make reasonable use of the wheel end space.

[0025] In one implementation, one of the two mounting surfaces has two pairs of bolt holes, which are symmetrically distributed vertically with respect to the center of the through hole. One pair of bolt holes is used for a fixed connection with a pair of bolts, wherein:

[0026] When an electromechanical braking device is used to brake the left wheel of a vehicle, a pair of bolts are fixedly connected to one of the pair of bolt holes;

[0027] When an electromechanical braking device is used to brake the right wheel of a vehicle, a pair of bolts are fixedly connected to another pair of bolt holes.

[0028] In this implementation, by setting two pairs of symmetrical bolt holes, the compatibility and interchangeability of the electromechanical braking device can be improved, so that the electromechanical braking device can be adapted to both the left and right wheels of the vehicle.

[0029] In one implementation, the brake housing is used to house a circuit assembly, which includes a pressure sensor for detecting pressure generated when the brake's transmission assembly drives at least one friction pad and transmitting the pressure detection signal through at least one signal transmission line.

[0030] In this implementation, the brake housing houses a pressure sensor for detecting braking pressure, and a signal transmission line is used to transmit the detected signal to the driver to match and adjust the output torque, thereby ensuring smooth and reliable braking of the electromechanical braking device.

[0031] In one implementation, along the length of the transmission connector, pressure sensors are arranged on the side of the transmission connector facing the brake housing, and the side of the pressure sensors facing the brake housing is used to electrically connect at least one signal transmission line.

[0032] In this implementation, the pressure sensor is located on the brake transmission assembly near the driver side, and a wire extends from that side to shorten the extension length of the signal transmission line, which is beneficial for the internal space arrangement of the brake.

[0033] In one implementation, the driver includes a circuit board, a housing for housing the circuit board, the circuit board for fixing a control circuit for receiving signals from a pressure sensor.

[0034] In this implementation, the drive component of the driver is relatively large, and the corresponding housing of the driver is also large, which facilitates the structure of accommodating the circuit board.

[0035] In one implementation, the thickness direction of the circuit board is perpendicular to the mounting surface of the driver housing, and the drive components of the driver are arranged between the circuit board and the mounting surface of the driver housing.

[0036] In this implementation, the circuit board arrangement can compress the volume of the electromechanical braking device along the wheel axis, making efficient use of the wheel end space. Furthermore, the circuit board does not affect the transmission connection between the driver's transmission components and the brake's transmission components.

[0037] In one implementation, the driver includes a brake motor, a housing for housing the brake motor, and the brake motor for driving the drive's transmission assembly to rotate, wherein:

[0038] Along the length of the transmission connector, the brake motor is located on the side of the drive assembly facing the brake.

[0039] Along the radial direction of the transmission connector, the brake motor and the transmission assembly of the brake are arranged side by side.

[0040] In this implementation, the power output by the brake motor is transmitted to the friction pads via a "U"-shaped circuit, which compresses the volume of the electromechanical braking device along the wheel axis and makes reasonable use of the wheel end space.

[0041] In one implementation, the drive assembly includes an input shaft and an output shaft that are drive-connected, wherein:

[0042] The input and output shafts are arranged at radial intervals along the transmission connector;

[0043] Along the axial direction of the input shaft, the input shaft and the motor shaft of the brake motor are driven coaxially;

[0044] Along the axial direction of the output shaft, the output shaft and the transmission connector are driven coaxially.

[0045] In this implementation, the input and output shafts of the driver are side by side and connected in a transmission manner, which can realize the reversing transmission of the output power of the brake motor and reduce the length of the electromechanical braking device.

[0046] In one implementation, the transmission connector and the output shaft are an integral structure; or, the transmission connector and the transmission assembly of the brake are an integral structure.

[0047] In this implementation, the transmission connector can be integrated with the output shaft or the rotary input component, eliminating the transmission structure at one end of the rotary connector and further reducing the overall size of the electromechanical braking device.

[0048] Secondly, this application provides a vehicle including wheels and an electromechanical braking device provided in any of the above implementations, wherein the length direction of the transmission connecting member in the electromechanical braking device is parallel to the wheel axle.

[0049] The vehicle provided in the second aspect of this application uses the electromechanical braking device provided in the first aspect of this application for braking. Because the electromechanical braking device provided in the first aspect of this application compresses the overall volume by utilizing the mounting surface mating between the housings, the vehicle of this application can obtain a larger interior space.

[0065] This application provides a vehicle including wheels and the aforementioned electromechanical braking device, wherein the length direction of the transmission connecting member in the electromechanical braking device is parallel to the wheel axle.

[0066] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the working scenario of the vehicle 1000 provided in the embodiments of this application. Figure 2 This is a schematic diagram of the internal structure of the electromechanical braking device 100 provided in the embodiments of this application. To clearly illustrate the internal functional structure of the electromechanical braking device 100, in... Figure 1 The structure of part of the housing in the electromechanical braking device 100 is omitted. For example... Figure 1 As shown, the vehicle 1000 provided in this embodiment includes wheels 1001 and an electromechanical braking device 100. The electromechanical braking device 100 is fixed to the frame of the vehicle 1000 and is positioned corresponding to the wheel 1001. The electromechanical braking device 100 is used to brake the wheel 1001.

[0067] In one embodiment, a brake disc is coaxially fixed to the wheel 1001. Figure 3 The diagram shows a brake disc 21. During the movement of the vehicle 1000, the brake disc rotates synchronously with the wheel 1001. The electromechanical braking device 100 is fixed to the frame and is set corresponding to the brake disc. The electromechanical braking device 100 generates friction through contact with the brake disc to brake the brake disc and indirectly brake the wheel 1001.

[0068] It should be noted that, in Figure 1In the illustrated embodiment, only one wheel 1001 and one electromechanical braking device 100 are used as examples for illustrative purposes. In practical applications, some wheels or each wheel 1001 in the vehicle 1000 may be equipped with an electromechanical braking device 100.

[0069] like Figure 1 and 2 As shown, the electromechanical braking device 100 includes a driver 10 and a brake 20. The driver 10 is used to provide driving force to the brake 20. The brake 20 is used to generate internal mechanism action after receiving power to brake the wheel 1001 (i.e., brake disc), thereby realizing the braking of the vehicle 1000.

[0070] The electromechanical braking device 100 also includes a transmission connector 30 between the driver 10 and the brake 20. The transmission connector 30 is drively connected between the driver 10 and the brake 20 and is used to transmit power from the driver 10 to the brake 20, thereby enabling the driver 10 to drive the brake 20 to brake the wheel 1001. The length of the transmission connector 30 is parallel to the axle of the wheel 1001 (i.e., the axis of rotation of the brake disc).

[0071] In one embodiment, the driver 10 includes a brake motor 11 and a transmission assembly 12, the transmission assembly 12 of the driver 10 being driveably connected between the brake motor 11 and a transmission connector 30. Specifically, the transmission connector 30 is driveably connected between the transmission assembly 12 of the driver 10 and the transmission assembly of the brake 20 (in... Figure 4 The diagram shows the transmission assembly 23 of the brake 20. The brake motor 11 rotates through the transmission assembly 12 of the driver 10 to drive the transmission assembly 23 of the brake 20 to move, thereby braking the wheel 1001 (i.e., the brake disc).

[0072] In one embodiment, the housing 14 of the driver 10 is used to house the transmission assembly 12. The transmission assembly 12 includes an input shaft 121 and an output shaft 122 spaced apart. A drive connection is established between the input shaft 121 and the output shaft 122. Figure 1 In the schematic diagram, the input shaft 121 and output shaft 122 within the transmission assembly 12 of the driver 10 are connected by a belt drive, but Figure 1 This is only for illustration and description of the transmission method between the input shaft 121 and the output shaft 122 in possible embodiments, and does not limit the transmission method between the input shaft 121 and the output shaft 122 to only one. Figure 1 The belt drive is shown. In one embodiment, the housing 14 of the driver 10 can also be used to house the brake motor 11.

[0073] That is, in other embodiments of this application, the transmission method between the input shaft 121 and the output shaft 122 may be, but is not limited to, gear transmission, chain transmission, belt transmission or other transmission methods that can realize the transmission connection between the input shaft 121 and the output shaft 122.

[0074] In one embodiment, such as Figure 2 As shown, along the length of the transmission connector 30, the brake motor 11 and the brake 20 are located on the same side of the transmission assembly 12 of the driver 10, that is, the brake motor 11 is located on the side of the transmission assembly 12 of the driver 10 facing the brake 20. And along the radial direction of the transmission connector 30, the brake motor 11 and the transmission assembly of the brake 20 are arranged side by side.

[0075] The input shaft 121 and output shaft 122 are arranged radially at intervals along the transmission connector 30, and the axial directions of both the input shaft 121 and output shaft 122 are parallel to the length direction of the transmission connector 30. It can be understood that by arranging the input shaft 121 and output shaft 122 side-by-side and connected in the transmission assembly 12 of the driver 10, the reverse transmission of the output power of the brake motor 11 can be achieved, thus reducing the length of the electromechanical braking device 100.

[0076] In one embodiment, the motor shaft 111 of the brake motor 11 is coaxially driven with the input shaft 121 along the axial direction of the input shaft 121. Furthermore, the transmission connector 30 is coaxially driven with the output shaft 122 along the axial direction of the output shaft 122.

[0077] The brake motor 11, acting as a power source, outputs power by rotating its own axis via a motor shaft 111. The motor shaft 111 of the brake motor 11 is coaxially driven by the input shaft 121 of the transmission assembly 12. The rotation of the motor shaft 111 synchronously drives the input shaft 121 to rotate, thus inputting power into the transmission assembly 12. Power is input into the transmission assembly 12 via the input shaft 121 and output from the transmission assembly 12 via the output shaft 122. The output shaft 122 is coaxially driven by the transmission connector 30. When the output shaft 122 rotates, it synchronously drives the transmission connector 30 to rotate, transmitting power through the transmission connector 30 to the brake 20, thereby enabling the driver 10 to drive the brake 20 to brake the vehicle 1000.

[0078] In other words, the transmission path of the power output by the brake motor 11 within the electromechanical braking device 100 can be, but is not limited to, the motor shaft 111 of the brake motor 11 → input shaft 121 → output shaft 122 → transmission connector 30 → brake 20, thereby enabling the driver 10 to drive the brake 20 to brake.

[0079] Understandably, the power output by the brake motor 11 is transmitted via the transmission assembly 12 of the driver 10 to the transmission connector 30, and then via the transmission connector 30 to the brake 20, driving the brake 20 to brake. This allows the power output by the brake motor 11 to be transmitted to the friction pads (in a U-shaped circuit) via a U-shaped path. Figure 4 The diagram shows friction pad 22), meaning that the power transmission path of the electromechanical braking device 100 forms a folding effect along the axial direction of the wheel 1001, compressing the size of the electromechanical braking device 100 along the axial direction of the wheel 1001 and making reasonable use of the wheel end space of the vehicle 1000.

[0080] It should be noted that, in Figure 2 In the embodiments shown, only one possible arrangement of the functional structural devices within the electromechanical braking device 100 of this application is described as an example, but it is not limited to this arrangement and transmission connection method. In other embodiments of the electromechanical braking device 100 of this application, the arrangement and connection method of the brake motor 11, the transmission component 12 of the driver 10, the transmission connector 30 and the brake 20 can be adjusted according to actual design requirements and application scenarios. This application does not make specific limitations in this regard.

[0081] One embodiment, please continue reading Figure 2 The housing 14 of the driver 10 is used to house the circuit board 13, that is, the circuit board 13 is housed within the housing 14 of the driver 10. The circuit board 13 is used to fix the control circuit, which is used to receive signals to coordinate the operation of various functional circuits and realize the various functions of the electromechanical braking device 100 in braking the vehicle 1000. The transmission component 12 of the driver 10 is relatively large, and the housing 14 of the driver 10 is also relatively large to facilitate the structure that accommodates the circuit board 13.

[0082] Along the length of the transmission connector 30, the circuit board 13 is located on the side of the drive assembly 12 of the driver 10 away from the brake 20. That is, along the length of the transmission connector 30, the circuit board 13 and the brake 20 are positioned on opposite sides of the drive assembly 12 of the driver 10, with the brake 20 located on the side of the drive assembly 12 of the driver 10 closer to the brake motor 11. The drive assembly 12 of the driver 10 is arranged between the circuit board 13 and the mounting surface of the housing 14 of the driver 10. The circuit board 13 does not affect the transmission connection between the drive assembly 12 of the driver 10 and the drive assembly 23 of the brake 20.

[0083] For example, when the control circuit of the circuit board 13 is electrically connected to the brake motor 11 of the driver 10, it can control the power output state of the brake motor 11, thereby meeting the different braking needs of the user for the vehicle 1000.

[0084] In one embodiment, the thickness direction of the circuit board 13 is parallel to the length direction of the transmission connector 30, that is, the thickness direction of the circuit board 13 is perpendicular to the mounting surface of the housing 14 of the driver 10. The thickness direction of the circuit board 13 can be understood as the direction in which the plate-like circuit board 13 is perpendicular to its own plane. By setting the thickness direction of the circuit board 13 to be parallel to the length direction of the transmission connector 30, the arrangement of the circuit board 13 can complement the arrangement of other functional structures within the electromechanical braking device 100, thereby compressing the volume of the electromechanical braking device 100 along the axial direction of the wheel 1001 and making reasonable use of the wheel end space.

[0085] Please refer to the following: Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the external structure of the brake 20 provided in the embodiment of this application. Figure 4 For this application Figure 3 A schematic cross-sectional view of the brake 20 provided in the illustrated embodiment. To clearly illustrate the braking process of the brake 20, in... Figure 4 The schematic diagram omits some of the structure of the brake 20.

[0086] In one embodiment, such as Figure 3 and Figure 4 As shown, the brake 20 includes friction pads 22 and a transmission assembly 23. In one embodiment, there are two friction pads 22, one of which is attached to the housing 24 of the brake 20 (see...). Figure 5 The two friction plates 22 are slidably connected, and the other friction plate 22 is fixedly connected to the housing 24 of the brake 20. The two friction plates 22 work together with the brake motor 11, the transmission assembly 12 of the driver 10 and the transmission connector 30 to drive the transmission assembly 23 of the brake 20 to drive one of the friction plates 22 to slide relative to the brake disc 21 so that the two friction plates 22 come closer to each other.

[0087] In one embodiment, two friction pads 22 are arranged on opposite sides of the brake disc 21 along the thickness direction of the brake disc 21, and the two friction pads 22 can be oriented towards each other (e.g., ...). Figure 4 (as indicated by the solid arrow in the middle), or far apart from each other (such as...) Figure 4 The brake disc 21 moves in the direction indicated by the dashed arrow (in the middle) so that it can abut against the brake disc 21 when the two friction pads 22 are close to each other, or release the brake disc 21 when the two friction pads 22 are far apart. The thickness direction of the brake disc 21 can be understood as the axis of rotation of the brake disc 21.

[0088] Understandably, when the two friction pads 22 come together and abut against the brake disc 21, the two friction pads 22 can respectively contact the two opposite end faces of the brake disc 21 and form friction, thereby reducing the rotational speed of the brake disc 21. Since the brake disc 21 rotates synchronously with the wheel 1001, the decrease in the rotational speed of the brake disc 21 will synchronously drive the wheel 1001 to decrease its rotational speed, thereby creating a braking effect on the wheel 1001, and thus enabling the electromechanical braking device 100 to brake the vehicle 1000.

[0089] exist Figure 4 In the example, along the thickness direction of the brake disc 21, the transmission component 23 of the brake 20 is located on one side of the brake disc 21, and the transmission component 23 of the brake 20 is used to drive at least one friction pad 22 to move along the thickness direction of the brake disc 21, so as to realize the movement of the two friction pads 22 towards each other or away from each other.

[0090] The transmission assembly 23 of the brake 20 is connected to the transmission connector 30 and is used to convert the rotational motion of the transmission connector 30 into a displacement motion along the thickness direction of the brake disc 21, so as to drive at least one friction pad 22 to move along the thickness direction of the brake disc 21. Figure 4 As shown, the thickness direction of the brake disc 21 is parallel to the length direction of the transmission connector 30. Therefore, it can also be understood that the transmission component 23 of the brake 20 can convert the rotational motion of the transmission connector 30 into movement along the length direction of the transmission connector 30.

[0091] In one embodiment, the transmission assembly 23 of the brake 20 includes a rotary input 231 and a sliding output 232. The transmission assembly 23 of the brake 20 is used to convert the rotational motion of the rotary input 231 into the displacement motion of the sliding output 232 to drive at least one friction plate 22.

[0092] The rotary input component 231 is driven between the sliding output component 232 and the transmission connector 30. The transmission component 23 of the driver 10 is coaxially driven with the rotary input component 231 through the transmission connector 30, that is, the rotary input component 231 and the transmission connector 30 rotate coaxially.

[0093] The sliding output member 232 is driven between the rotary input member 231 and at least one friction plate 22, and the displacement direction of the sliding output member 232 is parallel to the length direction of the transmission connector 30.

[0094] Understandably, the transmission connector 30 rotates around its own axis, causing the rotary input component 231, which is coaxially connected to it, to rotate synchronously. This allows the power input from the driver 10 to be input into the transmission assembly 23 of the brake 20 via the rotary input component 231. The rotary input component 231 rotates around its own axis and synchronously causes the sliding output component 232 to move, transmitting the power input from the transmission connector 30 to the transmission assembly 23 of the brake 20 to the sliding output component 232. The sliding output component 232 then drives at least one friction pad 22 to move along the thickness direction of the brake disc 21, thereby enabling the brake 20 to brake the vehicle 1000.

[0095] For example, in Figure 4 In the illustration, the transmission component 23 of the brake 20 may be, but is not limited to, a ball screw 23a, which converts the rotational motion input from the transmission connector 30 into linear displacement motion that drives the friction plate 22 to move. In one embodiment, the ball screw 23a includes a meshing screw 231a and a threaded sleeve 232a, wherein the screw 231a is configured as a rotational input component 231, and the threaded sleeve 232a is configured as a sliding output component 232.

[0096] The lead screw 231a is coaxially driven with the transmission connector 30, and the screw sleeve 232a is used to push the friction plate 22 to move along the length of the transmission connector 30 and abut against the brake disc 21 to brake the vehicle 1000.

[0097] Since the lead screw 231a and the sleeve 232a mesh and drive each other, when the lead screw 231a is driven by the transmission connector 30 to rotate along its own rotation axis, the rotation action of the lead screw 231a is transmitted to the sleeve 232a, which in turn can drive the sleeve 232a to make a displacement along the length direction of the lead screw 231a.

[0098] The threaded sleeve 232a moves toward the brake disc 21 along the thickness direction of the brake disc 21, and drives the friction pad 22 to move toward the brake disc 21 along the thickness direction of the brake disc 21, so that the friction pad 22 can contact the end face of the brake disc 21 and form friction force, thereby achieving the braking effect of the brake disc 21.

[0099] Understandably, the ball screw 23a has high transmission accuracy and low friction loss. When used in conjunction with the transmission connector 30, it can improve the transmission efficiency and transmission reliability of the electromechanical braking device 100 of this application.

[0100] It should be noted that, in Figure 4In the illustration, only one possible embodiment of the transmission component 23 of the brake 20 is described as an example, but it does not limit the possible implementation of the transmission component 23 of the brake 20 in this application to this. In other embodiments of this application, the transmission component 23 of the brake 20 may also adopt other structural components or devices that can convert the rotational motion input from the transmission connector 30 into linear motion, and the embodiments of this application do not specifically limit this.

[0101] In one embodiment, the transmission connector 30 and the transmission assembly 23 (specifically, the rotary input component 231) of the brake 20 are an integral structure.

[0102] In one embodiment, the transmission connector 30 and the transmission assembly 12 (specifically the output shaft 122) of the driver 10 are integrated into one structure.

[0103] Understandably, the transmission connector 30 is connected between the output shaft 122 of the transmission assembly 12 of the driver 10 and the rotary input 231. By setting the transmission connector 30 and the output shaft 122 as an integral structure, or setting the transmission connector 30 and the rotary input 231 as an integral structure, the transmission structure at one end of the transmission connector 30 can be eliminated, further reducing the overall volume of the electromechanical braking device 100.

[0104] Please see Figure 5 - Figure 7 , Figure 5 This is a schematic diagram showing the external structure of the electromechanical braking device 100 provided in an embodiment of this application, with some parts of the structure hidden. Figure 6 For this application Figure 5 A cross-sectional view of the electromechanical braking device 100 provided in the illustrated embodiment. Figure 7 For this application Figure 5 An exploded structural diagram of the electromechanical braking device 100 provided in the illustrated embodiment is shown. To clearly illustrate the structure of the electromechanical braking device 100 of this application, in... Figure 5 - Figure 7 The schematic diagram omits some structural components, such as the brake disc 21.

[0105] like Figure 5 - Figure 7 As shown, the transmission assembly 12 of the driver 10 is housed in the housing 14 of the driver 10, and the transmission assembly 23 of the brake 20 is housed in the housing 24 of the brake 20.

[0106] In one embodiment, the housing 14 of the driver 10 is used to house the transmission component 12 of the driver 10, and the housing 24 of the brake 20 is used to house the transmission component 23 of the brake 20. By providing housings to respectively house the transmission component 12 of the driver 10 and the transmission component 23 of the brake 20, it is possible to provide support and fixation for the transmission component 12 of the driver 10 and the transmission component 23 of the brake 20 to ensure the normal operation of the driver 10 and the brake 20, while also providing protection for the transmission component 12 of the driver 10 and the transmission component 23 of the brake 20, preventing dust, impurities, etc. from the external environment from entering the driver 10 or the brake 20 and affecting its working performance and service life.

[0107] The housing 14 of the driver 10 and the housing 24 of the brake 20 each include a mounting surface, and the two mounting surfaces are used for fixed connection with each other.

[0108] In one embodiment, in Figure 5 - Figure 7 In the schematic diagram, the mounting surface of the housing 14 of the actuator 10 is shown as the first mounting surface 141, and the mounting surface of the housing 24 of the brake 20 is shown as the second mounting surface 241. The first mounting surface 141 and the second mounting surface 241 are fixedly connected to achieve a fixed connection between the housing 14 of the actuator 10 and the housing 24 of the brake 20, thereby achieving a mutual fixing effect between the actuator 10 and the brake 20.

[0109] Meanwhile, the actuator 10 and the brake 20 are fixed to each other through two mounting surfaces, so that the housing 14 of the actuator 10 and the housing 24 of the brake 20 can fit tightly with a small gap, which can reduce the volume occupied by the actuator 10 and the brake 20, further reduce the volume of the electromechanical braking device 100 of this application, and achieve the effect of miniaturization design.

[0110] A through hole is provided on the first mounting surface 141. Figure 5 - Figure 7 The through hole schematically formed on the first mounting surface 141 is designated as the first through hole 1411. The second mounting surface 241 has a through hole at a position corresponding to the first through hole 1411. Figure 5 - Figure 7 The through hole shown on the second mounting surface 241 is the second through hole 2411. The two through holes are used together to avoid the transmission connector 30 between the transmission assembly 12 of the driver 10 and the transmission assembly 23 of the brake 20.

[0111] Understandably, since the transmission connector 30 is connected between the transmission assembly 12 of the driver 10 and the transmission assembly 23 of the brake 20 to transmit the power output by the brake motor 11 of the driver 10 to the transmission assembly 23 of the brake 20, the two opposite ends of the transmission connector 30 in the longitudinal direction need to extend into the housing 14 of the driver 10 and the housing 24 of the brake 20 respectively, so as to be connected to the transmission assembly 12 of the driver 10 and the transmission assembly 23 of the brake 20 respectively.

[0112] By providing a first through hole 1411 on the first mounting surface 141 and a second through hole 2411 on the second mounting surface 241, and aligning the first through hole 1411 and the second through hole 2411 along the length direction of the transmission connector 30, the two opposite ends of the transmission connector 30 along its own length direction can pass through the first through hole 1411 and the second through hole 2411 to extend into the housing 14 of the driver 10 and the housing 24 of the brake 20, respectively.

[0113] The housing 14 of the driver 10 and the housing 24 of the brake 20 can be fixedly connected by bolts 40.

[0114] For example, the housing 14 of the driver 10 and the housing 24 of the brake 20 are fixedly connected by a pair of bolts 40, which are radially symmetrically distributed relative to the center of the through hole to ensure the force balance between the two mounting surfaces.

[0115] like Figure 6 As shown, a pair of bolts 40 includes two bolts 40a. The two bolts 40a can be arranged symmetrically along the radial direction of the first through hole 1411 or the second through hole 2411 relative to the center of the first through hole 1411 or the second through hole 2411, so as to achieve a fixed connection between the housing 14 of the actuator 10 and the housing 24 of the brake 20 at different positions.

[0116] Meanwhile, by setting two of the bolts 40 in a pair of bolts 40 to be symmetrically arranged about the through hole, the stability of the fixed connection between the housing 14 of the driver 10 and the housing 24 of the brake 20 can be improved, thereby ensuring that the functional components inside the driver 10 and the functional components inside the brake 20 can work stably.

[0117] In one implementation, the housing 14 of the actuator 10 and the housing 24 of the brake 20 are fixedly connected by a pair of bolts 40, and the pair of bolts 40 are arranged approximately vertically. It is understood that by symmetrically arranging two of the bolts 40a approximately vertically relative to the center of the first through hole 1411 or the second through hole 2411, the two bolts 40a can be fixed approximately above and below the two housings respectively, further improving the stability and reliability of the fixed connection between the actuator 10 and the brake 20.

[0118] Meanwhile, by setting two housings to be fixedly connected by a pair of bolts 40, and the arrangement direction of the pair of bolts 40 is roughly in the vertical direction, the horizontal dimension of the electromechanical braking device 100 can be compressed, and there is no need to add an additional structural position for installing the two bolts 40a in the horizontal direction. This reduces the horizontal dimension of the two housings, so as to make reasonable use of the wheel end space.

[0119] In one embodiment, one of the two mounting surfaces is provided with two pairs of bolt holes, which are symmetrically distributed in the vertical direction with respect to the center of the through hole, wherein one pair of bolt holes is used for fixed connection with a pair of bolts 40.

[0120] For example, please refer to Figure 8 , Figure 8 For this application Figure 7 The illustrated embodiment provides a partial structural enlarged view of the electromechanical braking device 100 at position A. (See diagram below.) Figure 8 As shown, two pairs of second bolt holes 2412 are provided on the second mounting surface 241, and the two pairs of second bolt holes 2412 are symmetrically distributed in the vertical direction relative to the center of the second through hole 2411.

[0121] Alternatively, each pair of second bolt holes 2412 includes two second bolt holes 2412a, which are arranged vertically at intervals and symmetrically about the center of the second through hole 2411. Simultaneously, the two second bolt holes 2412a located on the same side of the second through hole 2411 in the vertical direction are also symmetrically arranged horizontally about the center of the second through hole 2411. Alternatively, it can be understood that the four second bolt holes 2412a in the two pairs of second bolt holes 2412 are arranged symmetrically in pairs about the second through hole 2411 in both the horizontal and vertical directions.

[0122] Meanwhile, at least one pair of first bolt holes 1412 are provided on the first mounting surface 141 corresponding to any pair of second bolt holes 2412 on the second mounting surface 241, and two of the first bolt holes 1412a in the pair of first bolt holes 1412 are respectively provided to correspond to the two second bolt holes 2412a in the pair of second bolt holes 2412.

[0123] In one embodiment, the axis of the first bolt hole 1412a coincides with that of a second bolt hole 2412a.

[0124] In one embodiment, the axes of the first bolt hole 1412a and the corresponding second bolt hole 2412a coincide with the rotation axis of the transmission connector 30.

[0125] In one embodiment, the first bolt hole 1412a and its corresponding second bolt hole 2412a have the same shape and the same area.

[0126] Understandably, by having a pair of first bolt holes 1412 on the first mounting surface 141 correspond to a pair of second bolt holes 2412 on the second mounting surface 241, a pair of bolts 40 can pass through a pair of first bolt holes 1412 and their corresponding first and second bolt holes 2412 along the length direction of the transmission connector 30, so that the pair of bolts 40 can achieve the function of fixing, so as to fix the housing 14 of the driver 10 and the housing 24 of the brake 20, that is, to achieve the effect of fixing the housing 14 of the driver 10 and the housing 24 of the brake 20.

[0127] It should be noted that, in Figure 8 In the illustration, the structural shape and dimensions of each first bolt hole 1412a and each second bolt hole 2412a can be identical, which improves the compatibility between each pair of first bolt holes 1412 and any pair of second bolt holes 2412. This allows the housing 14 of the driver 10 to be fixedly connected to the housing 24 of the brake 20 when the electromechanical braking device 100 corresponds to wheels 1001 located at different positions, thus enabling the braking function of the corresponding wheel 1001. In other words, it improves the compatibility of the electromechanical braking device 100 and the interchangeability between wheels 1001 at different positions.

[0128] However, the embodiments of this application do not limit the structural shape and size of each first bolt hole 1412a and each second bolt hole 2412a to be the same. In other embodiments of this application, the structural shape and size of each first bolt hole 1412a and each second bolt hole 2412a can be adjusted according to actual design requirements and application scenarios, and the embodiments of this application do not specifically limit this.

[0129] At the same time, Figure 8The illustration uses the example of a pair of first bolt holes 1412 on the first mounting surface 141 and two pairs of second bolt holes 2412 on the second mounting surface 241 as an example, but it is not limited to this number of bolt hole pairs on each mounting surface. That is, in other embodiments of this application, the number of bolt hole pairs on each mounting surface can be adjusted according to actual design requirements and application scenarios. For example, it is also possible, but not limited to, having two pairs of first bolt holes 1412 on the first mounting surface 141 and one pair of second bolt holes 2412 on the second mounting surface 241.

[0130] In one embodiment, when the electromechanical braking device 100 is used to brake the left wheel of the vehicle 1000, a pair of bolts 40 are fixedly connected to a pair of bolt holes.

[0131] In one embodiment, when the electromechanical braking device 100 is used to brake the right wheel of the vehicle 1000, a pair of bolts 40 are fixedly connected to another pair of bolt holes.

[0132] Understandably, by setting two pairs of symmetrical bolt holes, the compatibility and interchangeability of the electromechanical braking device 100 can be improved, so that the electromechanical braking device 100 can be adapted to both the left and right wheels of the vehicle 1000.

[0133] Please combine Figure 7 See also Figure 9 and Figure 10 , Figure 9 For this application Figure 7 The illustrated embodiment provides a partial structural enlarged view of the electromechanical braking device 100 at position B. Figure 10 For this application Figure 7 The schematic diagram shows the external structure of the housing 24 of the brake 20 provided in the embodiment from one side. A circuit assembly 50 is provided in the housing 14 of the driver 10 or the housing 24 of the brake 20. The circuit assembly 50 can be electrically connected to the circuit board 13 housed in the housing 14 of the driver 10 to realize signal transmission between the circuit board 13 and the circuit assembly 50.

[0134] For example, circuit assembly 50 may be electrically connected to circuit board 13 via signal transmission line 60, but is not limited to that connection. That is, a signal transmission line 60 may be provided between circuit assembly 50 and circuit board 13, with both ends of the signal transmission line 60 electrically connected to the control circuits of circuit assembly 50 and circuit board 13, respectively, to realize the signal transmission function between the control circuits of circuit assembly 50 and circuit board 13.

[0135] For example, such as Figure 7 and Figure 9As shown, the housing 24 of the brake 20 is used to house the circuit assembly 50, which may include, but is not limited to, a pressure sensor 51. The pressure sensor 51 is used to detect the pressure generated when the transmission assembly 23 of the brake 20 drives at least one friction plate 22, and transmits the pressure detection signal through at least one signal transmission line 60. At this time, the control circuit on the circuit board 13 is used to receive the signal from the pressure sensor 51.

[0136] In one embodiment, the pressure sensor 51 is housed in the housing 24 of the brake 20, and along the length of the transmission connector 30, the pressure sensor 51 and at least one friction plate 22 are arranged on both sides of the transmission assembly 23 of the brake 20.

[0137] exist Figure 9 In the schematic diagram, along the length of the transmission connector 30, or which can also be understood as along the axial direction of the transmission assembly 23 of the brake 20, the pressure sensor 51 and the two friction pads 22 are respectively located on opposite sides of the transmission assembly 23 of the brake 20, with the pressure sensor 51 located on the side of the transmission assembly 23 of the brake 20 closer to the driver 10. That is, the pressure sensor 51 is arranged on the side of the transmission connector 30 facing the mounting surface (second mounting surface 241) of the housing 24 of the brake 20. The driver 10 is electrically connected to the pressure sensor 51 via the signal transmission line 60, and the driver 10 is used to receive the pressure detected by the pressure sensor 51 to adjust the output torque.

[0138] That is, one end of the signal transmission line 60 extends into the housing 14 of the driver 10 and is electrically connected to the control circuit on the circuit board 13 housed within the housing 14 of the driver 10, while the other end extends into the housing 24 of the brake 20 and is electrically connected to the pressure sensor 51, thereby enabling signal transmission between the circuit board 13 and the pressure sensor 51. When the brake motor 11 of the driver 10 drives the transmission assembly 23 of the brake 20 to drive at least one friction plate 22, the pressure sensor 51 detects the pressure applied to the friction plate 22 by the transmission assembly 23 of the brake 20 and transmits the detected pressure value to the circuit board 13 of the driver 10 via the signal transmission line 60. The circuit board 13 receives the pressure value detected by the pressure sensor 51 and controls the rotational speed of the brake motor 11 based on the obtained pressure value to adjust the output torque of the driver 10.

[0139] Understandably, by setting up a pressure sensor 51 and electrically connecting it to the driver 10 to detect the braking pressure applied to the friction pad 22 by the brake 20 in real time, the braking status of the electromechanical braking device 100 on the vehicle 1000 can be monitored in real time. This allows the electromechanical braking device 100 to meet the user's braking requirements while simultaneously adjusting the output torque of the driver 10 to ensure smooth and reliable braking. By placing the pressure sensor 51 on the side of the transmission assembly 23 of the brake 20 near the driver 10, the extension length of the signal transmission line 60 can be shortened, which is beneficial for the internal space arrangement of the brake 20.

[0140] In one embodiment, a signal transmission line 60 is led out from the side of the pressure sensor 51 away from at least one friction plate 22, that is, the side of the pressure sensor 51 facing the mounting surface (second mounting surface 241) of the housing 24 of the brake 20 is used to electrically connect at least one signal transmission line 60.

[0141] Understandably, by extending the signal transmission line 60 from the side of the pressure sensor 51 away from at least one friction plate 22 to electrically connect it to the driver 10, the extension length of the signal transmission line 60 can be further shortened, facilitating its extension from the mounting surface. This also simplifies the layout design of the signal transmission line 60 within the housing 14 of the driver 10 and the housing 24 of the brake 20, preventing excessively long signal transmission lines from resulting in overly complex routing designs and spatial structures within the two housings. Simultaneously, minimizing the extension length of the signal transmission line 60 to simplify its routing within the two housings improves the connection stability and signal transmission reliability of the signal transmission line 60.

[0142] It should be noted that, in Figure 9 The illustration only provides an example of one possible routing design for the signal transmission line 60, and does not imply that the actual structural shape, dimensions, and routing design of the signal transmission line 60 are identical. In the embodiments of this application, the actual structural shape, dimensions, and routing design of the signal transmission line 60 are adjusted according to actual design requirements.

[0143] In one embodiment, at least one mounting surface includes at least one recess 70 for circumventing at least one signal transmission line 60 for electrically connecting at least one circuit assembly 50 housed in the housing 14 of the driver 10 or the housing 24 of the brake 20.

[0144] This application specification provides an exemplary example of at least one recess 70 provided on the second mounting surface 241.

[0145] In one embodiment, Figure 7 and Figure 10 In the schematic diagram, the second mounting surface 241 has at least one groove 70, and each groove 70 extends in a direction parallel to the second mounting surface 241, that is, the extension direction of the groove 70 is parallel to the plane direction of the mounting surface on which it is located. The groove 70 includes an inlet end 71 and an outlet end 72. Along the extension direction of the groove 70, the inlet end 71 is located on the side of the groove 70 closer to the second through hole 2411, and the outlet end 72 is located on the side of the groove 70 away from the second through hole 2411.

[0146] The input terminal 71 connects to the interior of the housing 14 of the actuator 10 or the interior of the housing 24 of the brake 20. Figure 7 - Figure 10 In the diagram, the input end 71 is connected to the interior of the housing 24 of the brake 20. When the signal transmission line 60 is led out from the pressure sensor 51, the signal transmission line 60 can extend out of the housing 24 of the brake 20 from the input end 71 of the groove 70 and extend into the groove 70.

[0147] The output terminal 72 is located at the edge of the mounting surface, and the signal transmission line 60, which extends into the groove 70, protrudes from the output terminal 72 onto the mounting surface. Figure 7 and Figure 10 In the illustration, the output terminal 72 is located at the edge of the second mounting surface 241, and the signal transmission line 60 extends from the output terminal 72 out of the mounting surface.

[0148] In one embodiment, the second through hole 2411 is close to the center of the second mounting surface 241. It can also be understood that the center of the second through hole 2411 can coincide with the geometric center of the second mounting surface 241 or be close to the geometric center of the second mounting surface 241.

[0149] Understandably, when the second through hole 2411 is positioned near the center of the second mounting surface 241, since the wire inlet end 71 of the groove 70 is close to the second through hole 2411, the wire inlet end 71 of the groove 70 is also relatively close to the center of the second mounting surface 241. This makes the distance between the wire outlet end 72 and the wire inlet end 71 located at the edge of the second mounting surface 241 approximately equal or not significantly different. Consequently, the electromechanical braking device 100 can extend from the second mounting surface 241 with a relatively short distance when corresponding to wheels 1001 at different positions, further improving the compatibility and adaptability of the electromechanical braking device 100. At the same time, by positioning the wire inlet end 71 of the groove 70 relatively close to the center of the second mounting surface 241, it also facilitates the sealing and protection of the interior of the brake housing 24.

[0150] In one embodiment, the groove 70 extends along a straight line parallel to the mounting surface, and the extension line of the line connecting the outlet end 72 to the inlet end 71 of the groove 70 passes through the center of the through hole.

[0151] For example, such as Figure 10 As shown, along the planar direction of the second mounting surface 241, the extension shape of the groove 70 is a straight line, and the extension line of the line connecting the outlet end 72 to the inlet end 71 of the groove 70 passes through the center of the second through hole 2411. That is, in the planar direction of the second mounting surface 241, the groove 70 extends radially along the second through hole 2411.

[0152] Understandably, setting the extension shape of the groove 70 to a straight line simplifies and facilitates the machining and manufacturing of the groove 70 on the mounting surface of the housing, thereby reducing the manufacturing difficulty and precision requirements of the groove 70 and thus reducing manufacturing costs. At the same time, since the shortest distance between two points is a straight line, setting the extension shape of the groove 70 to a straight line can further shorten the extension path of the signal transmission line 60 on the mounting surface.

[0153] In one embodiment, there are two grooves 70, which are symmetrically distributed in the vertical direction with respect to the center of the through hole.

[0154] For example, such as Figure 10 As shown, two grooves 70 are formed on the second mounting surface 241, and the two grooves 70 are symmetrically distributed in the vertical direction with respect to the center of the second through hole 2411. That is, the two grooves 70 are symmetrical in the vertical direction, and at any horizontal height, the distance between the two grooves 70 and the center of the second through hole 2411 is equal.

[0155] By setting two symmetrical grooves 70, the compatibility and interchangeability of the electromechanical braking device 100 can be improved, so that the electromechanical braking device 100 can be adapted to wheels 1001 at different positions of the vehicle 1000, such as the left wheel and the right wheel of the vehicle 1000.

[0156] For example, when the electromechanical braking device 100 is used to brake the left wheel of the vehicle 1000, the signal transmission line 60 extends out of the mounting surface through a groove 70.

[0157] For example, when the electromechanical braking device 100 is used to brake the right wheel of the vehicle 1000, the signal transmission line 60 extends out of the mounting surface through another groove 70.

[0158] In one embodiment, along the circumference of the through hole, one of a pair of bolts 40a is located between two recesses 70.

[0159] It should be noted that, in Figure 7 and Figure 10In the example provided, the groove 70 is exemplified only by being formed on the mounting surface of the housing 24 of the brake 20, but it is not limited to the groove 70 being formed only on the second mounting surface 241. In other embodiments of this application, the groove 70 may also be formed on the mounting surface of the housing 14 of the driver 10, that is, on the first mounting surface 141. In the scheme of this application, the groove 70 can be interpreted as the gap between the two mounting surfaces. Whether the groove 70 is specifically formed on the mounting surface of the housing 24 of the brake 20 or the mounting surface of the housing 14 of the driver 10 can be adjusted according to actual design requirements or the usage scenario of the electromechanical braking device 100, etc., and this application embodiment does not specifically limit this.

[0160] For example, in one possible embodiment, a portion of the groove 70 may be formed on the second mounting surface 241, and another portion of the groove 70 may be formed at a corresponding position on the first mounting surface 141. The two portions of the structure on the two mounting surfaces are aligned with each other to cooperate in forming the groove 70 and to avoid the signal transmission line 60.

[0161] At the same time, Figure 7 and Figure 10 In the example provided, only two grooves 70 are used as an example for illustration, but it is not limited to the number of grooves 70 in this embodiment being only two. The number of grooves 70 provided on the mounting surface in this embodiment can be adjusted according to the actual routing requirements or number of signal transmission lines 60, etc., and this application does not make specific limitations in this regard. When grooves 70 are simultaneously formed on the first mounting surface 141 and the second mounting surface 241, the groove structures on the two mounting surfaces cooperate with each other to form grooves 70. The depth dimension of the groove structure on each of the two mounting surfaces is small, which can respectively ensure the rigidity of the housing 14 of the driver 10 and the housing 24 of the brake 20, and avoid the phenomenon that forming grooves 70 on the same mounting surface may affect the rigidity of the housing 14 of the driver 10 or the housing 24 of the brake 20.

[0162] For one embodiment, please refer to Figure 11 , Figure 11 This is a cross-sectional structural schematic diagram of the seal 80 of the electromechanical braking device 100 provided in this application embodiment. The electromechanical braking device 100 includes a seal 80, which fills the gap between the signal transmission line 60 and the input terminal 71 to seal the housing 14 of the driver 10 or the housing 24 of the brake 20. By providing the seal 80, a sealing and protective effect can be achieved on the housing, that is, the sealing and protective effect of the housing 14 of the driver 10 or the housing 24 of the brake 20 on the internal functional structural components can be improved.

[0163] It should be noted that, in Figure 11The illustration only provides an example of setting a seal 80 between the signal transmission line 60 and the input terminal 71, but it does not limit the seal 80 to be located only in the gap between the signal transmission line 60 and the input terminal 71. In the embodiments of this application, the specific setting position and structural shape of the seal 80 can be adjusted according to actual design requirements, and this application does not impose specific limitations on this.

[0164] For example, in some possible embodiments, the seal 80 may also be disposed at other locations in the groove 70 and fill the gap between the inner surface of the groove 70 and the outer surface of the signal transmission line 60. Exemplarily, the seal 80 may be disposed in the middle section between the inlet end 71 and the outlet end 72 of the groove 70, or the seal 80 may be disposed at the outlet end 72 of the groove 70.

[0165] For example, in some possible embodiments, the seal 80 may also fill the entire recess 70 to fill the gap between the signal transmission line 60 and the recess 70.

[0166] The above embodiments, but not limited to the location and manner of the sealing member 80 in the above embodiments, can all achieve the effect of sealing and protecting the inside of the housing 14 of the driver 10 or the housing 24 of the brake 20 with the sealing member 80.

[0167] Typically, the internal mechanical transmission structure of an electromechanical braking device is relatively complex, and the internal space is narrow, which is not conducive to the layout of signal transmission lines in the electromechanical braking device.

[0168] The electromechanical braking device 100 of this application utilizes a groove 70 between the housing 14 of the actuator 10 and the housing 24 of the brake 20 to avoid the signal transmission line 60, allowing the circuit component 50 housed within one of the housings to extend the signal transmission line 60 through the gap between the two mounting surfaces. The signal transmission line 60 has a relatively short extension distance inside the housing of the electromechanical braking device 100, which facilitates the arrangement of the internal transmission components of the electromechanical braking device 100 and reduces the overall size of the electromechanical braking device 100. Simultaneously, the signal transmission line 60 outside the housing is convenient for arrangement and maintenance.

[0169] The vehicle 1000 of this application uses the electromechanical braking device 100 provided in any of the above embodiments of this application for braking. Because the electromechanical braking device 100 provided in any of the above embodiments of this application compresses its overall volume by utilizing the mounting surface mating between the housings, the vehicle 1000 of this application can obtain a larger interior space. That is, because the vehicle 1000 of this application is equipped with the electromechanical braking device 100 provided in any of the above embodiments, the vehicle 1000 of this application possesses all the possible beneficial effects of the electromechanical braking device 100 provided in any of the above embodiments.

[0170] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the scope of protection of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
