[0095] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0096] According to the first aspect of this application, referring to Figures 1 to 6 As shown, this application provides a detection device 100, which can be used, for example, to detect a vehicle braking device, wherein the vehicle braking device is part of the vehicle braking system, that is, the detection device 100 provided in this application can be integrated into the vehicle braking system for use.

[0097] The vehicle braking system includes at least an electrical device and a hydraulic device driven by the electrical device. As a specific example, the electrical device may include a drive motor, and the hydraulic device may include a hydraulic cylinder and a piston. In the braking system, when the rotor of the drive motor rotates, it drives the piston to slide relative to the hydraulic cylinder via a transmission method such as a lead screw and nut, or a gear and rack transmission. This causes a change in the hydraulic pressure of the fluid within the hydraulic cylinder, which in turn acts on the brake, providing a corresponding braking force to the wheels.

[0098] It is understood that the cooperation between electrical and hydraulic devices constitutes at least a part of a typical drive-by-wire hydraulic braking system. The improvement focus of this application is not on the specific cooperation structure between the electrical and hydraulic devices; those skilled in the art can configure them flexibly as needed, and these specific details will not be elaborated upon herein.

[0099] The testing device 100, as a component for testing vehicle braking systems, is referred to in this application. Figure 1 and Figure 2 As shown, the detection device 100 includes: a first sensor 110, a second sensor 120, and a mounting bracket 130.

[0100] The first sensor 110 is used to detect the electrical components of the vehicle braking system, that is, the first sensor 110 can be used to detect some parameters of the electrical components, such as the speed of the drive motor. The second sensor 120 is used to detect the hydraulic components of the vehicle braking system, that is, the second sensor 120 can be used to detect some parameters of the hydraulic components, such as the displacement of the piston.

[0101] Reference Figure 1 and Figure 2 As shown, the mounting bracket 130 includes a first mounting portion 131 and a second mounting portion 132. The first mounting portion 131 is used to mount the first sensor 110, and the second mounting portion 132 is used to mount the second sensor 120. The first mounting portion 131 and the second mounting portion 132 are positioned at different locations on the mounting bracket 130, so that the first sensor 110 and the second sensor 120 are positioned in two different areas on the mounting bracket 130. In practical use, the mounting bracket 130 can be integrated near the aforementioned electrical and hydraulic devices. The first sensor 110 and the second sensor 120 can act on different areas around the mounting bracket 130, thereby detecting the electrical and hydraulic devices located in different areas around the mounting bracket 130 respectively.

[0102] By adopting the above solution, and by providing a first mounting part 131 and a second mounting part 132 on the mounting bracket 130, the first sensor 110 and the second sensor 120 can be integrated simultaneously. Different sensors used for detecting the electrical and hydraulic components of the braking system can be integrated on the mounting bracket 130. Each sensor can be pre-installed on the mounting bracket 130, and then the mounting bracket 130 can be assembled with the electrical and hydraulic components. This facilitates the assembly of each sensor on the braking system, thereby reducing assembly difficulty. Simultaneously, the mounting bracket 130 can serve as a mounting reference for each sensor to cooperate with other parts of the braking system, improving the overall assembly accuracy of the braking system.

[0103] In some embodiments, refer to Figure 1 andFigure 2 As shown, the detection device 100 further includes a first conductor 140. The first conductor 140 is electrically connected to the first sensor 110, enabling it to power the first sensor 110 or transmit electrical signals emitted by the first sensor 110. These electrical signals contain information parameters of the electrical device detected by the first sensor 110, such as the rotor speed of the drive motor in the electrical device. In this case, the first sensor 110 can be specifically configured as a speed sensor for use in a vehicle braking system. The specific structure and principle of the speed sensor for detecting the rotor speed of the drive motor are not detailed here.

[0104] As a specific example, the first conductor 140 is, for instance, a PIN pin connected to the first sensor 110. More specifically, one end of the PIN pin is connected to the first sensor 110, and the other end is directly connected or indirectly connected via a wire to the vehicle control unit (ECU), thereby enabling the ECU to receive information parameters of the electrical devices detected by the first sensor 110. At least a portion of the first conductor 140 is embedded in the mounting bracket 130, which positions and mounts the first conductor 140. More specifically, the mounting bracket 130 may be further made of insulating material such as plastic, at least in the portion surrounding the first conductor 140, to insulate the first conductor 140.

[0105] In some embodiments, refer to Figure 1 As shown, at least a portion of the first conductor 140 extends from the first end A1 of the mounting bracket 130, facilitating the connection of the first conductor 140 with external components such as the ECU.

[0106] In some embodiments, refer to Figure 1 and Figure 2 As shown, the first sensor 110 includes a first chip 111 and a first circuit board 112.

[0107] The first chip 111 is used to acquire motor parameters of the electrical device; that is, the first chip 111 is the specific structure in the first sensor 110 used to detect the electrical device. The first circuit board 112 is electrically connected to the first chip 111 to transmit the motor parameters acquired by the first chip 111. The first chip 111 is connected to the first circuit board 112, for example, by soldering. The first circuit board 112 is connected to the first conductor 140 so that the first chip 111 is electrically connected to the first conductor 140 through the first circuit board 112, thereby enabling the transmission of electrical signals from the first chip 111 to the first conductor 140, or enabling the first conductor 140 to supply power to the first chip 111. The first chip 111, for example, is a TMR magnetic encoding chip, which has the characteristics of fast response speed, suitability for dynamic measurement, low power consumption, and strong anti-interference ability.

[0108] As a specific embodiment, the first sensor 110 includes a first Hall sensor 113. A Hall sensor is a non-contact sensor that achieves its detection function by detecting changes in the magnetic flux density of the area it detects. In practical applications, refer to... Figure 2 and Figure 3 As shown, for example, a multi-pole magnetic ring 200 is provided on the rotor of the motor, so that the multi-pole magnetic ring 200 is coaxially arranged with the rotor of the motor, and the multi-pole magnetic ring 200 is located within the detection range of the magnetic sensitive surface S of the Hall sensor. In this way, when the rotor speed changes and causes the magnetic induction intensity generated by the multi-pole magnetic ring 200 in a local area to change, the first Hall sensor 113 detects the change in magnetic induction intensity to detect the rotor speed of the drive motor. That is, in some embodiments, the motor parameters include the rotational speed of the drive motor rotor of the electrical device.

[0109] The first Hall sensor 113 does not directly contact the rotor of the drive motor during use, which is beneficial to the stable use of the drive motor and the first sensor 110.

[0110] In some embodiments of this application, reference is made to Figure 3 and Figure 4 As shown, the magnetic sensitive surface S of the first Hall sensor 113 can be further configured to be inclined to the rotation center line L of the drive motor rotor of the electrical device. Since the magnetic attenuation of the magnetic ring in the air medium is nonlinear, compared with mounting the magnetic sensitive surface S perpendicular or parallel to the magnet surface, this design can effectively compensate for nonlinear errors and make the sensor output waveform less distorted.

[0111] In some embodiments, refer to Figure 3 and Figure 4As shown, the tilt angle α between the magnetic sensitive surface S of the first Hall sensor 113 and the rotation center line L of the drive motor rotor of the electrical device ranges from 30° to 60°. By adopting this scheme, the angle between the magnetic sensitive surface S and the rotation center line L of the rotor is limited. Combined with the aforementioned scheme, this is equivalent to limiting the angle between the magnetic sensitive surface S and the axis of the multipole pair magnetic ring. This is beneficial for the first Hall sensor 113 to more sensitively sense changes in magnetic induction intensity, thereby ensuring detection accuracy.

[0112] As an exemplary description of a specific structure for positioning and mounting the first sensor 110 on the first mounting portion 131, in some embodiments, reference is made to... Figure 1 and Figure 2 As shown, one of the first mounting portion 131 and the first circuit board 112 is provided with a first assembly portion 131a. The other of the first mounting portion 131 and the first circuit board 112 is provided with a first mating portion 112a. The first assembly portion 131a and the first mating portion 112a form a mutually fitting connection to position the first circuit board 112 onto the first mounting portion 131. Using the above solution, the first sensor 110 is positioned and mounted onto the first mounting portion 131 by the mutual fitting of the first assembly portion 131a and the first mating portion 112a, so that the first sensor 110 is stably mounted onto the mounting bracket 130.

[0113] In the specific design, the first assembly part 131a is configured as a first protrusion 131b formed on the first mounting part 131 or the first circuit board 112; the first mating part 112a is configured as a first positioning hole 112b formed on the first mounting part 131 or the first circuit board 112. The first protrusion 131b is embedded in the first positioning hole 112b, and the first protrusion 131b and the first positioning hole 112b can be further configured as an interference fit. By inserting the first protrusion 131b into the first positioning hole 112b, the first sensor 110 is positioned and mounted on the mounting bracket 130.

[0114] In a further embodiment, the first protrusion 131b may be heat-fused, that is, after the first protrusion 131b is embedded in the first positioning hole 112b, the end of the first protrusion 131b is heat-fused to prevent the first protrusion 131b from dislodging from the first positioning hole 112b, thereby completing the fixation of the first sensor 110 on the mounting bracket 130.

[0115] In some embodiments, refer to Figure 1 and Figure 2As shown, the first mounting part 131 is provided with a first mounting groove 131c for the first circuit board 112 to be embedded. By forming the first mounting groove 131c to accommodate the first circuit board 112, the first circuit board 112 and the mounting bracket 130 are connected in a mutually fitting relationship, and the wall thickness of the mounting bracket 130 can be used to provide protection for the first circuit board 112.

[0116] Of course, the first protrusion 131b can be further defined as protruding from the groove wall of the first mounting groove 131c. On the one hand, the structure for limiting the first sensor 110 is formed in a concentrated manner on the first mounting part 131, which improves the space utilization. On the other hand, the first sensor 110 completes the engagement of the first protrusion 131b and the first positioning hole 112b during the process of embedding into the first mounting groove 131c, which makes it easy to integrate the first sensor 110 onto the mounting bracket 130.

[0117] It should be noted that, since the first conductor 140 is embedded in the mounting bracket 130, the first conductor 140 will generate heat when energized. Therefore, a first hollow groove 130a can be further formed on the mounting bracket 130. (Refer to...) Figure 2 As shown, the first perforated groove 130a connects the interior and exterior of the mounting bracket 130. The portion of the first conductor 140 embedded in the mounting bracket 130 is configured such that at least part of it protrudes from the mounting bracket 130 through the first perforated groove 130a, so that the first conductor 140 can dissipate heat to the outside by utilizing the perforated groove, thereby improving the operational stability of the detection device 100.

[0118] In practical applications, the first circuit board 112 often has multiple wiring positions to connect the first conductor 140. Correspondingly, the detection device 100 may include multiple first conductors 140, which are electrically connected to the first circuit board 112 to realize the transmission of electrical signals. Further, referring to... Figure 2 and Figure 5 As shown, at least a portion of the first conductors 140 are formed by cutting the same first conductor blank 400 and are spaced apart on the mounting bracket 130. That is, the blanks forming the first conductors 140 are an integral structure. At this time, the mounting bracket 130 can be manufactured by casting or other methods. Before or during casting, the first conductor blank 400 is pre-embedded in the mounting bracket 130. After the mounting bracket 130 is cast, the first conductor blank 400 is embedded in the mounting bracket 130. Then, for example, the first conductor blank 400 can be broken at the first hollow groove 130a, thereby fixing multiple first conductors 140 on the mounting bracket 130. Compared with the method of installing multiple first conductors 140 separately, this assembly method is more convenient to operate.

[0119] Similar to the form in which the first sensor 110 outputs an electrical signal, refer toFigure 1 and Figure 2 As shown, the detection device 100 may further include a second conductor 150. The second conductor 150 is, for example, a PIN pin, electrically connected to the second sensor 120. The second conductor 150 can be connected to the ECU, so that the second sensor 120 can, for example, transmit an electrical signal to the ECU through the second conductor 150. At least a portion of the second conductor 150 is embedded in a mounting bracket 130 to securely mount the second conductor 150 and, in some cases, to provide insulation protection for the second conductor 150.

[0120] In some embodiments, refer to Figure 1 As shown, at least a portion of the second conductor 150 extends from the first end of the mounting bracket 130, facilitating connection of the second conductor 150 to structures such as the ECU. Furthermore, both the first conductor 140 and the second conductor 150 extend from the first end of the mounting bracket 130, which is beneficial for wiring on the detection device 100.

[0121] In some embodiments, refer to Figure 2 As shown, the mounting bracket 130 is provided with a second hollow groove 130b. The second hollow groove 130b connects the interior and exterior of the mounting bracket 130. The portion of the second conductor 150 embedded in the mounting bracket 130 is configured such that at least part of it protrudes from the mounting bracket 130 through the second hollow groove 130b, which facilitates heat dissipation of the second conductor 150 from the second hollow groove 130b and helps to reduce the weight of the mounting bracket 130.

[0122] In some embodiments, refer to Figure 2 and Figure 5 As shown, the detection device 100 includes a plurality of second conductors 150. At least a portion of the second conductors 150 are formed by cutting from the same second conductor blank 500 and are spaced apart on the mounting bracket 130 to facilitate the assembly and forming of the second conductors 150 on the mounting bracket 130. In a specific embodiment, a portion of the first conductor blank 400 and a portion of the second conductor blank 500 can be connected as a whole. After being pre-embedded in the mounting bracket 130 and fixed to the mounting bracket 130 as it is formed, the first conductor blank 400 and the second conductor blank 500 can be broken apart, thereby facilitating the forming of the first conductor 140 and a portion of the second conductor 150.

[0123] In some embodiments, refer to Figure 2 and Figure 6 As shown, the second sensor 120 includes: a second chip 121 and a second circuit board 122.

[0124] The second chip 121 is used to acquire displacement parameters of the hydraulic device. For example, these displacement parameters may include the displacement of the brake piston of the hydraulic device. In other words, the second chip 121 is the specific structure used for detection within the second sensor 120. The second circuit board 122 is electrically connected to the sensor chip to transmit the displacement parameters acquired by the second chip 121. The second circuit board 122 is also connected to the second conductor 150, allowing the second chip 121 to be electrically connected to the second conductor 150 via the second circuit board 122, thereby enabling the information detected by the second chip 121 to be transmitted to components such as the ECU via the second conductor 150.

[0125] As a specific embodiment, the second sensor 120 includes a second Hall sensor 123. More specifically, a magnet 300 can be placed on the piston of the hydraulic device. As the magnet 300 moves with the piston, the magnetic induction intensity of the area detected by the second Hall sensor 123 changes due to the change in the relative position of the magnet 300 and the second sensor 120. The piston displacement is measured by measuring the change in magnetic induction intensity. The second Hall sensor 123 does not need to contact the piston during use, which is beneficial for the long-term stable use of the detection device 100.

[0126] As an exemplary description of a specific structure for positioning and mounting the second sensor 120 on the second mounting portion 132, in some embodiments, reference is made to... Figure 2 and Figure 6 As shown, one of the second mounting portion 132 and the second circuit board 122 is provided with a second assembly portion 132a. The other of the second mounting portion 132 and the second circuit board 122 is provided with a second mating portion 122a. The second assembly portion 132a and the second mating portion 122a form a mutually fitting connection to position and mount the second circuit board 122 onto the second mounting portion 132. Through the mutual fitting of the second assembly portion 132a and the second mating portion 122a, the second sensor 120 is positioned and mounted onto the second mounting portion 132, so that the second sensor 120 is stably mounted onto the mounting bracket 130.

[0127] Reference Figure 2 and Figure 6 As shown, the second assembly portion 132a can be further configured as a second protrusion 132b formed on the second mounting portion 132 or the second circuit board 122, and the corresponding second mating portion 122a can be configured as a second positioning hole 122b formed on the second mounting portion 132 or the second circuit board 122. The second protrusion 132b is embedded in the second positioning hole 122b. The second protrusion 132b and the second positioning hole 122b can be further configured as an interference fit. By inserting the second protrusion 132b into the second positioning hole 122b, the second sensor 120 is positioned and mounted on the mounting bracket 130.

[0128] The second protrusion 132b can be heat-fused, that is, after the second protrusion 132b is embedded in the second positioning hole 122b, the end of the second protrusion 132b is heat-fused to prevent the second protrusion 132b from falling out of the second positioning hole 122b, thereby completing the fixation of the second sensor 120 on the mounting bracket 130.

[0129] In some embodiments, refer to Figure 2 and Figure 6 As shown, the second mounting portion 132 is provided with a second mounting groove 132c. The second mounting groove 132c is for the second circuit board 122 to be embedded in. By forming the second mounting groove 132c to accommodate the second circuit board 122, the second circuit board 122 and the mounting bracket 130 form a mutually fitting connection, and the wall thickness of the mounting bracket 130 can provide protection for the second circuit board 122.

[0130] For more specific solutions, refer to Figure 2 and Figure 6 As shown, the second protrusion 132b protrudes from the wall of the second mounting groove 132c. Similar to the previous description, the first protrusion 131b is located on the wall of the first mounting groove 131c. The above solution is beneficial to improving the space utilization of the mounting bracket 130 and facilitates the integration of the second sensor 120 onto the mounting bracket 130.

[0131] In some embodiments, refer to Figure 1 As shown, a first mounting portion 131 is formed on one end of the mounting bracket 130 along a first direction X1; a second mounting portion 132 is formed on one end of the mounting bracket 130 along a second direction X2, which is different from the first direction X1, so that the first sensor 110 and the second sensor 120 are spaced apart. Specifically, the first direction X1 and the second direction X2 are, for example, inclined or vertical. This arrangement allows the first sensor 110 and the second sensor 120 to face different areas around the mounting bracket 130. Considering that the first sensor 110 and the second sensor 120 are used to detect different parts of the vehicle braking system, this arrangement is advantageous because these different parts are respectively configured in different areas around the mounting bracket 130.

[0132] Of course, the mounting bracket 130 needs to be integrated with the electrical and hydraulic devices in a single space to ensure the detection accuracy of the first sensor 110 and the second sensor 120. This requires the mounting bracket 130 to be fixedly installed at a specific location on the vehicle.

[0133] In some embodiments, refer to Figure 6As shown, the mounting bracket 130 also includes a positioning part 133. The positioning part 133 is used to position the mounting bracket 130 for installation into the vehicle's braking system. Thus, by providing the positioning part 133, the mounting bracket 130 is integrated into a specific location on the vehicle, enabling the testing of electrical and hydraulic devices at that specific location.

[0134] In some embodiments, refer to Figure 6 As shown, the positioning part 133 is configured as a positioning support 134 protruding from the surface of the mounting bracket 130. Correspondingly, a hole can be provided at the position where the mounting bracket 130 is connected on the vehicle, so that the positioning support 134 can be inserted into the hole to achieve the positioning and installation of the mounting bracket 130 on the vehicle. The accompanying drawings of this application illustrate a specific embodiment in which the positioning support 134 is cross-shaped. In actual application, the positioning support 134 can also be polygonal, cylindrical, frustum-shaped, crescent-shaped, or other different shapes, as long as the positioning support 134 can be used to position the mounting bracket 130 on the vehicle. This application does not make a specific limitation in this regard.

[0135] In some embodiments, refer to Figure 2 As shown, the mounting bracket 130 is further provided with a fixing part 135. The fixing part 135 is used to fix the mounting bracket 130 to the vehicle braking system, so that in addition to being positioned by the positioning part 133, the mounting bracket 130 is also fixed to the vehicle by the fixing part 135, so that the first sensor 110 and the second sensor 120 can be stably present on the vehicle and realize the detection of different parts of the vehicle braking system.

[0136] In some embodiments, refer to Figure 2 As shown, the fixing part 135 is configured as a mounting hole 136 formed on the mounting bracket 130, and the mounting bracket 130 is fixed on the vehicle at the mounting hole 136, for example by a threaded connection.

[0137] In some embodiments, the detection device 100 further includes a bushing 160. The bushing 160 is embedded within the mounting hole 136 to form a fixed connection with the mounting bracket 130. The bushing 160 is made of, for example, metal and is pre-embedded in the mounting bracket 130 during its forming process. The bushing 160 can be used to enhance the strength of the connection structure between the mounting bracket 130 and the vehicle.

[0138] According to a second aspect of this application, a vehicle braking system is provided, including the detection device 100 described above. This vehicle braking system also includes, for example, the braking device described above. This vehicle braking system has the beneficial effects of the detection device 100, which will not be elaborated upon here. The accompanying drawings of this application do not show the specific structure of the braking device and other components in the vehicle braking system.

[0139] According to the third aspect of this application, referring to Figure 7 As shown, a vehicle 10 is also provided, including the detection device 100 described above, or including the vehicle braking system described above. This vehicle 10 possesses all the beneficial effects of the detection device 100 or the vehicle braking system described above, which will not be elaborated further here.

[0140] The vehicle 10 can be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this application does not make any specific restrictions on it.
