Description

Technical Field

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

[0002] Electromechanical braking devices mount a brake motor and friction pads via a clamp body. The brake motor drives the friction pads to slide towards the brake disc of the wheel during braking, while the clamp body holds the friction pads in place to ensure braking reliability. Therefore, the clamp body in an electromechanical braking device is relatively large and needs to possess a certain rigidity to prevent deformation or cracking, which can easily lead to an increase in the clamp body's weight. Utility Model Content

[0003] This application provides an electromechanical braking device with reinforced clamp body and a vehicle. By embedding reinforcement components in specific areas of the main structure of the clamp body, the overall structural stability of the clamp body is improved, ensuring reliable braking of the electromechanical braking device and facilitating weight reduction.

[0004] In a first aspect, this application provides an electromechanical braking device with a clamp-like body reinforcement. The clamp-like body of the electromechanical braking device includes a main structure and a reinforcing member. The main structure includes a connecting bridge and two mounting seats. The connecting bridge is used to fix the two mounting seats at intervals. The side of each mounting seat facing the other mounting seat is used to install a friction pad. The side of one mounting seat facing away from the other mounting seat is also used to fix a brake motor. The brake motor is used to drive the brake disc of the two friction pads to brake the wheel. The reinforcing member includes a connected bent section and an extension section. The bent section is embedded at the connection between the connecting bridge and one mounting seat. The extension section is embedded in the connecting bridge or in the mounting seat. The yield strength of the material of the reinforcing member is greater than the yield strength of the material of the main structure.

[0005] The electromechanical braking device provided in this application mounts a brake motor and two friction pads through the main structure of the clamp body. Two opposing sides of one mounting base are used to mount the brake motor and one friction pad respectively, while the side of the other mounting base facing the first mounting base is used to mount the other friction pad. During braking, the brake motor drives one friction pad to slide relative to one mounting base, and causes the other friction pad to slide with the clamp body towards the first friction pad, so that the two friction pads clamp the brake disc from both sides to brake the wheel.

[0006] The electromechanical braking device provided in this application also fixes two mounting seats at intervals via a connecting bridge, forming a structure in which the brake motor, one mounting seat, one friction pad, one brake disc, another friction pad, and another mounting seat are arranged in sequence. The connection point between the connecting bridge and one or the other mounting seat is a relatively weak area of ​​the clamp body under stress. The electromechanical braking device provided in this application improves the overall structural stability of the clamp body by embedding a reinforcing member at at least one of the two connection points, and the yield strength of the reinforcing member material is greater than the yield strength of the main structure material. The extension section is used to increase the contact area between the reinforcing member and the main structure, and improve the reliability of the connection between the reinforcing member and the main structure.

[0007] The electromechanical braking device provided in this application has a clamp body that is less prone to deformation during braking, resulting in higher reliability. The main structure of the clamp body can be made of a material with relatively low yield strength, thereby reducing the cost of the electromechanical braking device and facilitating weight reduction.

[0008] In one implementation, an extension is embedded in a connecting bridge along the extension direction of the mounting base. The connecting bridge includes an outer surface facing away from the mounting base, and the extension is spaced apart from the outer surface of the connecting bridge.

[0009] In this implementation, the connecting bridge is used to embed the extension section, resulting in a tighter connection between the reinforcement and the connecting bridge and better load-bearing capacity. The mounting base extends outward from one side of the connecting bridge, with the extension section located on the side of the connecting bridge closer to the mounting base. This improves the stress distribution on the reinforcement and enhances the overall structural stability of the clamp body.

[0010] In one implementation, along the extension direction of the mounting base, the extension section protrudes from the connecting bridge toward the outer surface of the mounting base.

[0011] In this implementation, the extension section is located on the outermost side of the connecting bridge facing the mounting base. The extension section is closer to the connection between the connecting bridge and the mounting base and closer to the area with the smallest radius of the connection between the connecting bridge and the mounting base, which can improve the stress conditions in this area and enhance the overall structural stability of the clamp body.

[0012] In one implementation, an extension is embedded in a mounting base along a direction in which two mounting bases are spaced apart. One mounting base includes an outer surface facing away from the other mounting base, and the extension is spaced apart from the outer surface of one mounting base.

[0013] In this implementation, the mounting base is used to embed the extension section, resulting in a tighter fit between the reinforcement and the mounting base and better load-bearing capacity. Positioning the reinforcement closer to the mounting base on the side facing the other mounting base improves the stress distribution on the reinforcement and enhances the overall structural stability of the clamp body.

[0014] In one implementation, along the direction in which the two mounting bases are spaced apart, the extension section protrudes from the outer surface of one mounting base toward the other mounting base.

[0015] In this implementation, the extension section is located on the outermost side of the mounting base facing another mounting base. The extension section is closer to the connection between the connecting bridge and the mounting base, and closer to the area with the smallest radius where the connecting bridge and the mounting base are connected. This can improve the stress conditions in this area and enhance the overall structural stability of the clamp body.

[0016] In one implementation, the two mounting bases are arranged parallel to the axial direction of the brake motor. This facilitates the brake motor driving the two friction pads to slide axially and brake the brake disc, thereby improving the braking efficiency of the electromechanical braking device provided in this application.

[0017] In one implementation, the width of the reinforcing member is smaller than the width of the main structure along the width direction of the friction plate, and the width direction of the friction plate is perpendicular to the extension direction of the mounting base and perpendicular to the direction in which the two mounting bases are spaced apart.

[0018] In this implementation, the friction pad slides relative to the caliper body along the axial direction of the brake motor and brakes the brake disc. The fact that the width direction of the friction pad is perpendicular to the axial direction of the brake motor increases the contact area with the brake disc, improving braking performance. Appropriately increasing the width of the caliper body's main structure along the width direction of the friction pad provides better support for the friction pad during braking, ensuring reliable braking.

[0019] Since the main force direction of the clamp body during braking is the axial direction of the brake motor and the extension direction of the mounting base, appropriately reducing the width of the reinforcement has little impact on the structural stability of the clamp body, which is beneficial to the lightweighting of the electromechanical braking device.

[0020] In one implementation, the clamp body includes a reinforcement member, which is symmetrically arranged with respect to the geometric center of the friction plate along the width direction of the friction plate.

[0021] In this implementation, the reinforcements are symmetrically distributed along the width of the friction pads, and the geometric center of the reinforcements coincides with the axis of the brake disc. The reinforcements provide better support for the friction pads during braking, which can improve the overall structural stability of the caliper body.

[0022] In one implementation, the clamp body includes multiple reinforcing members, which are spaced apart along the width direction of the friction pad.

[0023] In this implementation, the reinforcements along the width of the friction plate are more evenly distributed in the main structure of the clamp body, which can better improve the overall structural stability of the clamp body.

[0024] In one implementation, a plurality of reinforcing members include at least one pair of reinforcing members, each pair of reinforcing members being arranged symmetrically with respect to the geometric center of the friction plate along the width direction of the friction plate.

[0025] In this implementation, each pair of reinforcements is symmetrically distributed along the width of the friction pad, and the center of symmetry of each pair of reinforcements coincides with the axis of the brake disc. This can improve the support effect of each pair of reinforcements on the friction pad during braking, thereby improving the overall structural stability of the caliper body.

[0026] One implementation method involves embedding the reinforcement into the main structure through welding, gluing, integral casting, or interference fit.

[0027] In one implementation, the surface of the reinforcement member that is used to fit against the main structure includes multiple protrusions or multiple grooves.

[0028] In this implementation, multiple protrusions or grooves are provided on the surface of the reinforcement that is in contact with the main structure. This increases the contact area between the reinforcement and the main structure, making the connection between the reinforcement and the main structure tighter and ensuring that the reinforcement is reliably embedded in the main structure.

[0029] In one implementation, the main structure includes a groove for accommodating a reinforcement member, the spacing between the groove walls being less than the width of the reinforcement member, and the reinforcement member being used to form a dense layer on the groove walls, the density of the dense layer being greater than the density of the rest of the main structure.

[0030] In this implementation, the groove includes a pair of opposite groove walls, the distance between the pair of groove walls is less than the width of the reinforcement. After the reinforcement is embedded in the groove, it forms an interference fit with the main structure and adheres to the dense layer of the groove wall, ensuring that the reinforcement is tightly integrated with the main structure.

[0031] In one implementation, along the arrangement direction of the two mounting seats, the two opposite sides of the two mounting seats are constructed as a pair of groove walls. The reinforcement member is thus embedded in the two mounting seats in a U-shape, with each mounting seat used to fix an extension of the reinforcement member. The reinforcement member also includes an extension extending along the length direction of the connecting bridge.

[0032] In one implementation, the clamp body further includes a locating pin for embedding into the main structure and at least partially abutting the reinforcement member, and for limiting the relative displacement between the reinforcement member and the main structure.

[0033] In this implementation, the clamp body uses locating pins to confine the reinforcement within the main structure, preventing the reinforcement from shifting relative to the main structure.

[0034] In one implementation, one mounting bracket is used to mount the brake motor and friction pads, while a locating pin is located within another mounting bracket. Because the mounting bracket for the brake motor is larger, its structural stability is relatively good. The mounting bracket further away from the brake motor is relatively smaller, its structural stability is relatively poor, and it is prone to deformation. Using the locating pin to better hold the reinforcement components within the mounting bracket further away from the brake motor can improve the structural stability of the mounting bracket further away from the brake motor.

[0035] In one implementation, the yield strength of the material of the reinforcement is greater than or equal to 1700 MPa.

[0036] One implementation method is that the material of the reinforcement has a hardness greater than or equal to 58 HRC after heat treatment.

[0037] One implementation involves the tensile strength of the material of the reinforcement being greater than the tensile strength of the material of the main structure.

[0038] One implementation involves using a material whose elastic modulus is greater than that of the material of the main structure.

[0039] In one implementation, the elastic modulus of the material of the reinforcement component is greater than or equal to 169 GPa, and the elastic modulus of the material of the main structure is greater than or equal to 71 GPa.

[0040] One implementation involves using a material with a density greater than that of the main structure.

[0041] In one implementation, the density of the reinforcement material is greater than or equal to 7100 kg / m³. 3 The density of the main structure's material is greater than or equal to 2700 kg / m³. 3 .

[0042] In one implementation, the material of the reinforcement is cast iron, steel, or carbon fiber.

[0043] One implementation method involves using cast aluminum, aluminum alloy, magnesium alloy, or polymer plastic as the material for the main structure.

[0044] Among the various implementation methods, limiting the material properties of the reinforcement components further prevents cracking and deformation of the reinforcement components and improves the structural stability of the reinforcement components, thereby enhancing the overall structural stability of the clamp body and facilitating weight reduction.

[0045] In one implementation, the reinforcement includes two extension sections, which are respectively embedded in the connecting bridge and the mounting base, and a bending section is used to connect the two extension sections.

[0046] In this implementation, each end of the bent section of the reinforcement includes an extension section. The reinforcement is reliably fixed to the mounting base and the connecting bridge, which can improve the stress condition of the reinforcement and fix the mounting base and the connecting bridge respectively, thus avoiding relative deformation between the mounting base and the connecting bridge.

[0047] In one implementation, the connection between the connecting bridge and the mounting base includes a circular chamfer, and the bent section is arc-shaped, with the center of the arc of the bent section coinciding with the center of the circular chamfer.

[0048] In this implementation, at the connection between the connecting bridge and the mounting base, the extension path of the bent section is parallel to the radius of the circular chamfer at the connection. The thicknesses of the connecting bridge and the mounting base are relatively uniform, which is beneficial to simultaneously improving the structural stability of the connecting bridge, the mounting base, and the connection.

[0049] In one implementation, the reinforcement includes two bent sections, which are respectively embedded at the connection between the connecting bridge and the two mounting bases, and an extension section is embedded in the connecting bridge and used to connect the two bent sections.

[0050] In this implementation, the reinforcement component is embedded in a U-shaped structure between the two mounting bases, and the two bent sections are connected and fixed to each other, which can further improve the structural stability of the two connection points.

[0051] In one implementation, each of the two connection points includes a reinforcing member, wherein the reinforcing member at the connection point for fixing the brake motor mounting base has smaller dimensions than the other reinforcing member. Because the mounting base for fixing the brake motor has relatively good structural stability, increasing the volume of the reinforcing member at the mounting base furthest from the brake motor can improve the structural stability of the mounting base furthest from the brake motor.

[0052] In one implementation, the electromechanical braking device provided in this application includes a transmission mechanism for drivingly connecting a brake motor and a friction plate.

[0053] In one implementation, the mounting base for fixing the brake motor includes a through hole extending along the arrangement direction of the two mounting bases, the through hole being used to accommodate a transmission mechanism.

[0054] In one implementation, the mounting bracket for fixing the brake motor includes two lugs, which are positioned on either side of the mounting bracket along the width direction of the friction pad. The two lugs are used to slidably connect to the caliper bracket. During braking, the caliper body slides relative to the caliper bracket via the two lugs, causing another friction pad to displace towards the brake disc.

[0055] Secondly, this application provides a vehicle including wheels and an electromechanical braking device reinforced with clamps as provided in this application. The electromechanical braking device is fixed to the vehicle frame and is used to brake the brake discs of the wheels. This vehicle, while ensuring reliable braking, can reduce weight and manufacturing costs. Attached Figure Description

[0077] The technical solutions of the embodiments of this application will now be described 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 scope of protection of this application.

[0078] This application provides an electromechanical braking device with a reinforced clamp body. The clamp body of the electromechanical braking device includes a main structure and a reinforcing component. The main structure includes a connecting bridge and two mounting seats. The connecting bridge is used to fix the two mounting seats at intervals. Each mounting seat has a friction pad mounted on its side facing the other mounting seat. One of the mounting seats also has a brake motor mounted on its side facing away from the other mounting seat. The brake motor drives the brake disc of the wheel to brake the two friction pads. The reinforcing component includes a connected bent section and an extension section. The bent section is embedded at the connection between the connecting bridge and one of the mounting seats, and the extension section is embedded in the connecting bridge or in the mounting seat. The yield strength of the material of the reinforcing component is greater than the yield strength of the material of the main structure. The electromechanical braking device provided by this application has high structural stability, the clamp body is not easily deformed during braking, and it is low in cost and conducive to weight reduction.

[0079] This application provides a vehicle including wheels and an electromechanical braking device reinforced with clamps as provided in this application. The electromechanical braking device is fixed to the vehicle frame and is used to brake the brake discs of the wheels. This vehicle can reduce weight and manufacturing costs while ensuring reliable braking.

[0080] Please see Figure 1 This is a schematic diagram illustrating the structure of an electromechanical braking device 100 provided in one embodiment of this application in a vehicle 200.

[0081] The vehicle 200 provided in this application includes a frame, wheels, and an electromechanical braking device 100, such as Figure 1 As shown, an electromechanical braking device 100 is disposed at the wheel of the vehicle 200, and the wheel includes a brake disc 201. During the movement of the vehicle 200, the brake disc 201 rotates synchronously with the wheel hub. The electromechanical braking device 100 includes a caliper bracket 120, which is fixed to the frame of the vehicle 200. During braking, the electromechanical braking device 100 contacts the brake disc 201 to generate friction, thereby limiting the rotation of the wheel and braking the vehicle 200.

[0082] Please see Figure 2 and Figure 3 , Figure 2 This illustration shows a structural diagram of the clamp 10 provided in one embodiment of this application; Figure 3 This illustration shows the transmission diagram of an electromechanical braking device 100 provided in an embodiment of this application in a vehicle 200.

[0083] The electromechanical braking device 100 provided in this application includes a clamp body 10, which includes a main structure 11. The main structure 11 is used to mount a brake motor 103 and two friction pads 105. The two friction pads 105 are located on opposite sides of the brake disc 201. The brake motor 103 is used to drive the two friction pads 105 to slide toward the brake disc 201 and contact the brake disc 201 to form friction, thereby limiting the rotation of the wheel and braking the vehicle 200.

[0084] The main structure 11 includes a connecting bridge 112 and two mounting bases 111. For example... Figure 2 and Figure 3 As shown, two mounting seats 111 are located on both sides of the brake disc 201, and a connecting bridge 112 is used to fix the two mounting seats 111 to each other. That is, the connecting bridge 112 is used to fix the two mounting seats 111. In one embodiment, the two mounting seats 111 are arranged at intervals parallel to the axial direction of the brake motor 103.

[0085] Along the direction in which the two mounting seats 111 are spaced apart, each mounting seat 111 includes a side facing the other mounting seat 111, and the sides of the two mounting seats 111 are respectively used to mount a friction plate 105. Another side of one of the mounting seats 111 opposite to the other mounting seat 111 is also used to fix a brake motor 103, which is used to drive the brake disc 201 of the wheel to brake the two friction plates 105.

[0086] For ease of description, in the following embodiments, the mounting base 111 used to fix the brake motor 103 is defined as the first mounting base 1111, the other mounting base 111 is defined as the second mounting base 1112, the friction plate 105 mounted on the first mounting base 1111 is defined as the first friction plate 1051, and the friction plate 105 mounted on the second mounting base 1112 is defined as the second friction plate 1052.

[0087] Thus, along the arrangement direction of the two mounting seats 111, the first friction plate 1051 and the second friction plate 1052 are respectively arranged at intervals on both sides of the brake disc 201. The motor housing of the brake motor 103 is fixed to the side of the first mounting seat 1111 opposite to the first friction plate 1051. At this time, the friction plate 105 does not restrict the rotation of the brake disc 201.

[0088] During the braking process of vehicle 200, brake motor 103 drives the first friction pad 1051 to slide towards brake disc 201 along the arrangement direction of the two mounting seats 111. After the first friction pad 1051 contacts brake disc 201, brake motor 103 also drives caliper 10 to slide relative to brake disc 201 along the arrangement direction of the two mounting seats 111. The second friction pad 1052 follows caliper 10 to slide towards brake disc 201 and contacts brake disc 201, so that the two friction pads 105 contact brake disc 201 from both sides to form friction force, thereby limiting the rotation of brake disc 201 and clamping brake disc 201 to brake the wheel.

[0089] In one embodiment, the electromechanical braking device 100 further includes a transmission mechanism 104. The transmission mechanism 104 is used to drive the first friction plate 1051 and the motor shaft 1031. The driving force output by the motor shaft 1031 of the brake motor 103 is transmitted to the first friction plate 1051 via the transmission mechanism 104 to drive the first friction plate 1051 to slide relative to the first mounting base 1111 along the arrangement direction of the two mounting bases 111.

[0090] In one embodiment, such as Figure 3 As shown, the first mounting base 1111 includes a through hole 101, which extends through the first mounting base 1111 along the arrangement direction of the two mounting bases 111. The through hole 101 is used to fix and accommodate the transmission mechanism 104.

[0091] The electromechanical braking device 100 provided in this application includes a reinforcing member 12, which is embedded in the main structure 11. The yield strength of the material of the reinforcing member 12 is greater than the yield strength of the material of the main structure 11. The reinforcing member 12 is used to improve the overall structural stability of the clamp body 10. Specifically, the reinforcing member 12 includes a connected bent section 122 and an extension section 121. The bent section 122 is embedded at the connection between the connecting bridge 112 and a mounting base 111, and the extension section 121 is embedded in the connecting bridge 112 or in the mounting base 111.

[0092] Please see Figure 4 This is a schematic cross-sectional view of a clamp 10 provided in one embodiment of the present application.

[0093] In one embodiment, such as Figure 4 As shown, the clamp body 10 includes two reinforcing members 12. One reinforcing member 12 is located at the connection between the connecting bridge 112 and the first mounting base 1111, and the other reinforcing member 12 is located at the connection between the connecting bridge 112 and the second mounting base 1112. For ease of description, in subsequent embodiments, the reinforcing member 12 located at the connection between the connecting bridge 112 and the first mounting base 1111 is defined as the first reinforcing member 123, and the reinforcing member 12 located at the connection between the connecting bridge 112 and the second mounting base 1112 is defined as the second reinforcing member 124.

[0094] The first reinforcing member 123 includes a bent section 122 and an extension section 121. The bent section 122 of the first reinforcing member 123 is embedded at the connection between the connecting bridge 112 and the first mounting base 1111. The extension section 121 of the first reinforcing member 123 is embedded in the connecting bridge 112. One end of the extension section 121 of the first reinforcing member 123 is connected to its bent section 122, and the other end extends towards the second mounting base 1112 along the length direction of the connecting bridge 112.

[0095] The second reinforcement member 124 includes a bent section 122 and an extension section 121. The bent section 122 of the second reinforcement member 124 is embedded at the connection between the connecting bridge 112 and the second mounting base 1112. The extension section 121 of the second reinforcement member 124 is embedded in the second mounting base 1112. One end of the extension section 121 of the second reinforcement member 124 is connected to its bent section 122, and the other end extends away from the connecting bridge 112 along the extension direction of the mounting base 111.

[0096] like Figure 4 As shown, the two mounting seats 111 located on both sides of the connecting bridge 112 form a cantilever beam structure relative to the connecting bridge 112. Due to the poor load-bearing capacity of the cantilever beam, the connection between the connecting bridge 112 and the mounting seats 111 is prone to deformation.

[0097] Please see Figure 5 and Figure 6 , Figure 5 A schematic diagram of the stress simulation results of the clamp body 10' of the electromechanical braking device 100' in the prior art; Figure 6 This is a schematic diagram of the strain simulation results of the clamp 10' of the electromechanical braking device 100' in the prior art.

[0098] like Figure 5 and Figure 6 As shown, during the braking process of the existing electromechanical braking device 100', the location of maximum stress on the caliper 10' typically occurs at the connection between the connecting bridge 112' and the mounting base 111', i.e. Figure 5 Locations ①-④ in the diagram indicate that the connection between the connecting bridge 112' and the mounting base 111' is a weak point in the clamp body. During long-term use, this weak point in the clamp body 10' undergoes significant deformation, which can affect the control accuracy of the electromechanical braking device 100' and reduce the vehicle's braking performance. The weak point in the clamp body 10' may even fracture and fail, preventing the electromechanical braking device 100' from performing its braking action and posing a safety hazard to the user.

[0099] Compared to the clamp body 10' of the existing electromechanical braking device 100', the electromechanical braking device 100 provided in this application has a reinforcing member 12 embedded at the connection between the connecting bridge 112 and at least one mounting base 111. The yield strength of the material of the reinforcing member 12 is greater than the yield strength of the material of the main structure 11, thereby improving the overall structural stability of the clamp body 10. The extension section 121 is used to increase the contact area between the reinforcing member 12 and the main structure 11, and to improve the reliability of the connection between the reinforcing member 12 and the main structure 11.

[0100] The caliper body 10 of the electromechanical braking device 100 provided in this application has a higher overall yield strength, making it less prone to deformation during braking and more reliable, thus suitable for applications with high braking force and high deceleration. The overall yield strength of the caliper body 10, reinforced by the reinforcing member 12, is high, allowing the main structure 11 to be made of a material with relatively low yield strength, thereby reducing the manufacturing cost of the electromechanical braking device 100 and contributing to its lightweight design. Because the vehicle 200 provided in this application uses the aforementioned electromechanical braking device 100, it can reduce weight and manufacturing costs while ensuring reliable braking.

[0101] In one embodiment, the reinforcement 12 includes a bent section 122 and two extension sections 121. The two extension sections 121 are respectively embedded in the connecting bridge 112 and the mounting base 111, and the bent section 122 is used to connect the two extension sections 121.

[0102] Please see Figure 7 This is a schematic diagram of another cross-sectional structure of the clamp 10 provided in one embodiment of this application.

[0103] like Figure 7 As shown, the clamp body 10 includes a reinforcing member 12, which includes a bent section 122 and two extension sections 121. The bent section 122 is embedded at the connection between the connecting bridge 112 and the first mounting base 1111. One of the extension sections 121 is embedded in the first mounting base 1111, with one end connected to the bent section 122 and the other end extending away from the connecting bridge 112 along the extension direction of the mounting base 111. The other extension section 121 is embedded in the connecting bridge 112, with one end connected to the bent section 122 and the other end extending towards the second mounting base 1112 along the length direction of the connecting bridge 112. The reinforcement 12 is reliably fixed to the first mounting base 1111 and the connecting bridge 112 respectively, which can improve the stress condition of the reinforcement 12 and fix the first mounting base 1111 and the connecting bridge 112 respectively, thus avoiding relative deformation between the first mounting base 1111 and the connecting bridge 112.

[0104] In one embodiment, the bent section 122 of the reinforcement 12 is embedded at the connection between the connecting bridge 112 and the second mounting base 1112. Two extension sections 121 are respectively embedded within the second mounting base 1112 and the connecting bridge 112. The reinforcement 12 is reliably fixed to both the second mounting base 1112 and the connecting bridge 112, which also improves the stress distribution on the reinforcement 12 and secures both the second mounting base 1112 and the connecting bridge 112, preventing relative deformation between them.

[0105] In one embodiment, the reinforcement 12 includes two bent sections 122 and one extension section 121. The two bent sections 122 are respectively embedded at the connection between the connecting bridge 112 and the mounting base 111, and the extension section 121 is embedded in the connecting bridge 112 and serves to connect the two bent sections 122. The reinforcement 12 is U-shaped and embedded between the two mounting bases 111. The two bent sections 122 are connected and fixed to each other, which can further improve the structural stability of the connection between the two mounting bases 111 and the connecting bridge 112.

[0106] Please see Figure 8 and Figure 9 , Figure 8 This illustrates another cross-sectional structural diagram of the clamp 10 provided in one embodiment of this application; Figure 9 This illustration shows an exploded structural diagram of the clamp 10 provided in one embodiment of this application.

[0107] like Figure 8 and Figure 9 As shown, the clamp body 10 includes a first reinforcing member 123 and a second reinforcing member 124. Both the first reinforcing member 123 and the second reinforcing member 124 include a bent section 122 and an extension section 121. The bent section 122 of the first reinforcing member 123 is embedded at the connection between the connecting bridge 112 and the first mounting base 1111, and the bent section 122 of the second reinforcing member 124 is embedded at the connection between the connecting bridge 112 and the second mounting base 1112. The extension section 121 of the first reinforcing member 123 is embedded within the connecting bridge 112. One end of the extension section 121 is connected to the bent section 122 of the first reinforcing member, and the other end extends along the length of the connecting bridge 112 toward the second mounting base 1112 and is connected to the bent section 122 of the second reinforcing member 124. That is, the first reinforcement 123 and the second reinforcement 124 are connected as one unit to further improve the structural stability of the connection between the first mounting base 1111 and the connecting bridge 112 and the connection between the second mounting base 1112 and the connecting bridge 112.

[0108] In addition, one end of the extension 121 of the second reinforcement 124 is connected to the bent section 122 of the second reinforcement 124, and the other end extends along the extension direction of the mounting base 111 in a direction away from the connecting bridge 112, so that the second reinforcement 124 has a larger contact area with the main structure 11, thereby improving the reliability of the connection between the first reinforcement 123 and the second reinforcement 124 and the main structure 11.

[0109] Please see Figure 10 and Figure 11 , Figure 10 This illustrates another cross-sectional structural diagram of the clamp 10 provided in one embodiment of this application; Figure 11 This illustration shows another cross-sectional structure of the clamp 10 provided in one embodiment of the present application.

[0110] like Figure 10 and Figure 11 As shown, the reinforcement member 12 includes two bent sections 122 and three extension sections 121. One bent section 122 is embedded at the connection between the connecting bridge 112 and the first mounting base 1111, and another bent section 122 is embedded at the connection between the connecting bridge 112 and the second mounting base 1112. One extension section 121 is embedded within the connecting bridge 112 to connect the two bent sections 122. Another extension section 121 is embedded in the first mounting base 1111, with one end connected to the bent section 122 and the other end extending away from the connecting bridge 112 along the extension direction of the mounting base 111. Yet another extension section 121 is embedded in the second mounting base 1112, with one end connected to the bent section 122 and the other end extending away from the connecting bridge 112 along the extension direction of the mounting base 111.

[0111] Extensions 121 of the reinforcing member 12 are embedded in both the connecting bridge 112 and the two mounting bases 111, giving the reinforcing member 12 a larger contact area with the main structure 11 and further improving the reliability of the connection between the reinforcing member 12 and the main structure 11. In addition, the reinforcing member 12 secures the connecting bridge 112 and the two mounting bases 111 respectively, preventing relative deformation between the connecting bridge 112 and the two mounting bases 111.

[0112] In one embodiment, the connection between the connecting bridge 112 and the mounting base 111 includes a circular chamfer 109, and the bent section 122 is arc-shaped, with the center of the arc of the bent section 122 coinciding with the center of the circular chamfer 109.

[0113] like Figure 4As shown, the connection points between the connecting bridge 112 and the first mounting base 1111, and between the connecting bridge 112 and the second mounting base 1112, each include a circular chamfer 109. The circular chamfer 109 is used to reduce stress concentration in the main structure 11 and prevent cracking. The arc center of the bent section 122 of the first reinforcing member 123 and the arc center of the bent section 122 of the second reinforcing member 124 coincide with the centers of the two circular chamfers 109, respectively. At the connection points between the connecting bridge 112 and the mounting base 111, the extension paths of the bent sections 122 of the first reinforcing member 123 and the second reinforcing member 124 are parallel to the radii of the circular chamfers 109 at the two connection points, making the thicknesses of the connecting bridge 112, the first mounting base 1111, and the second mounting base 1112 relatively uniform, which is beneficial for simultaneously improving the structural stability of the connecting bridge 112, the first mounting base 1111, the second mounting base 1112, and the connection points.

[0114] In one embodiment, the yield strength of the material of the reinforcement 12 is greater than or equal to 1700 MPa. By limiting the reinforcement 12 to have a higher yield strength, the threshold for plastic deformation of the reinforcement 12 is increased, thereby reducing the plastic deformation of the reinforcement 12 and improving the structural stability of the reinforcement 12, as well as the overall structural stability of the clamp 10.

[0115] In one embodiment, the tensile strength of the material of the reinforcement 12 is greater than that of the material of the main structure 11. By limiting the tensile strength of the reinforcement 12, the reinforcement 12 can withstand greater stress, thus preventing the reinforcement 12 from cracking due to excessive stress.

[0116] In one embodiment, the material of the reinforcement 12 has a hardness greater than or equal to 58 HRC after heat treatment. In another embodiment, the elastic modulus of the material of the reinforcement 12 is greater than the elastic modulus of the material of the main structure 11.

[0117] In one embodiment, the elastic modulus of the material of the reinforcement 12 is greater than or equal to 169 GPa, and the elastic modulus of the material of the main structure 11 is greater than or equal to 71 GPa.

[0118] In the above embodiments, the hardness and elastic modulus of the reinforcement 12 are limited to reduce the deformation of the reinforcement 12, making the clamp body 10 less prone to deformation and having higher reliability. This avoids excessive deformation of the reinforcement 12 from affecting the control accuracy of the electromechanical braking device 100, thereby ensuring the braking effect of the vehicle 200.

[0119] In one embodiment, the density of the material of the reinforcement 12 is greater than the density of the material of the main structure 11.

[0120] In one embodiment, the density of the material of the reinforcement 12 is greater than or equal to 7100 kg / m³. 3 The density of the material of the main structure 11 is greater than or equal to 2700 kg / m³. 3 .

[0121] In the above embodiments, the density of the reinforcement 12 and the main structure 11 is limited to ensure the overall structural stability of the clamp body 10 and reduce the weight of the clamp body 10, which is beneficial to the lightweighting of the electromechanical braking device 100.

[0122] In one embodiment, the reinforcement 12 is made of cast iron, steel, or carbon fiber. The reinforcement 12 has a high yield strength to ensure the overall structural stability of the clamp body 10.

[0123] In one embodiment, the main structure 11 is made of cast aluminum, aluminum alloy, magnesium alloy, or polymer plastic. Because the reinforcing member 12 has a high yield strength to ensure the overall structural stability of the clamp body 10, the main structure 11 can be made of materials with lower yield strength or lighter weight, reducing the manufacturing cost and weight of the main structure 11, which is beneficial for the lightweighting of the electromechanical braking device 100.

[0124] In one embodiment, the extension 121 is embedded in the connecting bridge 112. Along the extension direction of the mounting base 111, the connecting bridge 112 includes an outer surface facing away from the mounting base 111, and the extension is spaced apart from the outer surface of the connecting bridge 112.

[0125] like Figure 4 As shown, the connecting bridge 112 includes a first surface 1121 facing away from the first mounting base 1111 and the second mounting base 1112. An extension 121 of the first reinforcing member 123 is embedded within the connecting bridge 112 and extends along the length of the connecting bridge 112. That is, along the extension direction of the mounting base 111, this extension 121 is spaced apart from the first surface 1121. The embedding of the extension 121 of the first reinforcing member 123 within the connecting bridge 112 makes the connection between the first reinforcing member 123 and the connecting bridge 112 tighter and improves the load-bearing effect. Both the first mounting base 1111 and the second mounting base 1112 extend outward from the side of the connecting bridge 112 facing away from the first surface 1121. The extension 121 of the first reinforcing member 123 is located on the side of the connecting bridge 112 closer to the first mounting base 1111 and the second mounting base 1112, which can improve the stress condition of the first reinforcing member 123 and enhance the overall structural stability of the clamp body 10.

[0126] In one embodiment, along the extending direction of the mounting base 111, the extension 121 is exposed on the outer surface of the mounting base 111 at the connecting bridge 112.

[0127] like Figure 11As shown, the connecting bridge 112 includes a second surface 1122 facing the first mounting base 1111 and the second mounting base 1112. Along the extending direction of the mounting base 111, one side of one of the two opposing sides of an extension segment 121 is attached to the second surface 1122, while the other side is exposed outside the connecting bridge 112. That is, the extension segment 121 is located at the outermost side of the connecting bridge 112 facing the mounting base 111. The extension segment 121 is closer to the connection point between the connecting bridge 112 and the mounting base 111, and closer to the area with the smallest radius at the connection between the connecting bridge 112 and the mounting base 111, which can improve the stress conditions in this area and enhance the overall structural stability of the clamp body 10.

[0128] In one embodiment, the extension 121 is embedded in a mounting base 111. Along the direction in which the two mounting bases 111 are spaced apart, one mounting base 111 includes an outer surface facing away from the other mounting base 111, and the extension 121 is spaced apart from the outer surface of one mounting base 111.

[0129] like Figure 4 As shown, the second mounting base 1112 includes a third surface 1113 facing away from the first mounting base 1111. An extension 121 of the second reinforcing member 124 is embedded within the second mounting base 1112 and extends away from the connecting bridge 112 along the extension direction of the mounting base 111, that is, the extension 121 is spaced apart from the third surface 1113 along the extension direction of the mounting base 1111. The embedding of the extension 121 of the second reinforcing member 124 within the second mounting base 1112 results in a tighter connection between the second reinforcing member 124 and the second mounting base 1112, and a better load-bearing effect. The second reinforcing member 124 is located closer to the side of the second mounting base 1112 facing the first mounting base 1111, which can improve the stress condition of the second reinforcing member 124 and enhance the overall structural stability of the clamp body 10.

[0130] In one embodiment, the extension 121 of the reinforcement 12 is embedded within the first mounting base 1111 and extends away from the connecting bridge 112 along the extending direction of the mounting base 111. Along the extending direction of the mounting base 111, the extension 121 is spaced apart from the outer surface of the first mounting base 1111 on the side facing away from the second mounting base 1112. Embedding the extension 121 within the first mounting base 1111 makes the connection between the reinforcement 12 and the first mounting base 1111 tighter and improves the load-bearing effect. The reinforcement 12's proximity to the first mounting base 1111 on the side facing the second mounting base 1112 improves the stress distribution of the reinforcement 12 and enhances the overall structural stability of the clamp body 10.

[0131] In one embodiment, along the direction in which the two mounting bases 111 are spaced apart, the extension 121 is exposed on the surface of one mounting base 111 toward the other mounting base 111.

[0132] like Figure 11 As shown, the second mounting base 1112 includes a fourth surface 1114 facing the first mounting base 1111. One extension 121 of the reinforcement 12 is embedded in the second mounting base 1112 and extends away from the connecting bridge 112 along the extension direction of the mounting base 111. Along the direction in which the two mounting bases 111 are spaced apart, one side of the two opposite sides of the extension 121 is attached to the fourth surface 1114, and the other side is exposed in the second mounting base 1112. That is, the extension 121 is located at the outermost part of the second mounting base 1112 facing the first mounting base 1111. The extension 121 is closer to the connection between the connecting bridge 112 and the second mounting base 1112, and closer to the area with the smallest radius of the connection between the connecting bridge 112 and the second mounting base 1112, which can improve the stress conditions in this area and improve the overall structural stability of the clamp body 10.

[0133] In one embodiment, the extension 121 of the reinforcement 12 is embedded in the first mounting base 1111. Along the direction in which the two mounting bases 111 are spaced apart, one side of the two opposite sides of the extension 121 is attached to the surface of the first mounting base 1111 facing the second mounting base 1112, while the other side is exposed outside the first mounting base 1111. That is, the extension 121 is located on the outermost layer of the first mounting base 1111 facing the second mounting base 1112. The extension 121 is closer to the connection between the connecting bridge 112 and the first mounting base 1111, and closer to the area with the smallest radius where the connecting bridge 112 and the first mounting base 1111 are connected, which can improve the stress conditions in this area and enhance the overall structural stability of the clamp body 10.

[0134] In one embodiment, along the width direction of the friction pad 105, the width of the reinforcement 12 is smaller than the width of the main structure 11, and the width direction of the friction pad 105 is perpendicular to the extension direction of the mounting base 111 and perpendicular to the direction in which the two mounting bases 111 are arranged at intervals.

[0135] Please see Figure 12 This is a schematic diagram of another cross-sectional structure of the clamp 10 provided in one embodiment of this application.

[0136] like Figure 12 As shown, the two bent segments 122 of the reinforcement 12 are respectively embedded at the connection between the first mounting base 1111 and the connecting bridge 112 and the connection between the second mounting base 1112 and the connecting bridge 112. Along the width direction of the friction plate 105, the width of both bent segments 122 is smaller than the width of the connection. The extension segment 121 of the reinforcement 12 is embedded in the connecting bridge 112.

[0137] Please combine Figure 3Along the width direction of the friction pad 105, the width of the extension 121 is smaller than the width of the connecting bridge 112. The friction pad 105 slides relative to the caliper 10 along the axial direction of the brake motor 103 and brakes the brake disc 201. The width direction of the friction pad 105 being perpendicular to the axial direction of the brake motor 103 can increase the contact area between the friction pad 105 and the brake disc 201, improving the braking effect of the electromechanical braking device 100. Appropriately increasing the width of the main structure 11 of the caliper 10 along the width direction of the friction pad 105 can provide better support for the friction pad 105 during braking, ensuring reliable braking.

[0138] Since the main force direction of the clamp body 10 during the braking process is the axial direction of the brake motor 103 and the extension direction of the mounting base 111, appropriately reducing the width of the reinforcement 12 has little impact on the structural stability of the clamp body 10, which is beneficial to the weight reduction of the electromechanical braking device 100.

[0139] In one embodiment, the clamp 10 includes a reinforcement 12, which is symmetrically arranged with respect to the geometric center of the friction plate 105 along the width direction of the friction plate 105.

[0140] Please see Figure 13 This is a schematic diagram of another cross-sectional structure of the clamp 10 provided in one embodiment of this application.

[0141] like Figure 13 As shown, the caliper body 10 includes a reinforcing member 12, which is centrally symmetrically distributed along the width direction of the friction pad 105. The geometric center of the reinforcing member 12 coincides with the axis of the brake disc 201. The reinforcing member 12 provides better support for the friction pad 105 during braking, thereby improving the overall structural stability of the caliper body 10.

[0142] In one embodiment, the clamp 10 includes a plurality of reinforcing members 12, which are spaced apart along the width direction of the friction pad 105.

[0143] Please see Figure 14 This is a schematic diagram of another cross-sectional structure of the clamp 10 provided in one embodiment of this application.

[0144] like Figure 14 As shown, the clamp body 10 includes three reinforcing members 12. The three reinforcing members 12 are arranged at intervals along the width direction of the friction plate 105, so that the reinforcing members 12 along the width direction of the friction plate 105 are more evenly distributed in the main structure 11 of the clamp body 10, which can better improve the overall structural stability of the clamp body 10.

[0145] In addition, the two reinforcing members 12 on both sides are symmetrically arranged with respect to the geometric center of the friction plate 105 along the width direction of the friction plate 105, and the one reinforcing member in the middle is symmetrically distributed along the width direction of the friction plate 105. This makes the center of symmetry of the three reinforcing members 12 coincide with the axis of the brake disc 201, which also makes the reinforcing members 12 provide better support for the friction plate 105 during braking, thereby improving the overall structural stability of the caliper body 10.

[0146] In one embodiment, the plurality of reinforcement members 12 includes at least one pair of reinforcement members 12, each pair of reinforcement members 12 being arranged symmetrically with respect to the geometric center of the friction plate 105 along the width direction of the friction plate 105.

[0147] like Figure 12 As shown, the caliper body 10 includes a pair of reinforcing members 12, which are centrally symmetrically arranged and spaced apart from each other along the width direction of the friction pad 105. The center of symmetry of the pair of reinforcing members 12 coincides with the axis of the brake disc 201 to improve the support effect of the pair of reinforcing members 12 on the friction pad 105 during braking, thereby improving the overall structural stability of the caliper body 10.

[0148] Please see Figure 15 This is a schematic diagram of another cross-sectional structure of the clamp 10 provided in one embodiment of this application.

[0149] like Figure 15 As shown, the caliper body 10 includes a pair of first reinforcing members 123 and a pair of second reinforcing members 124, which are spaced apart along the arrangement direction of the two mounting seats 111. The pair of first reinforcing members 123 are centrally symmetrical and spaced apart along the width direction of the friction pad 105, and the pair of second reinforcing members 124 are centrally symmetrical and spaced apart along the width direction of the friction pad 105. The centers of symmetry of the pair of first reinforcing members 123 and the pair of second reinforcing members 124 coincide with the axis of the brake disc 201, so as to improve the support effect of the first reinforcing members 123 and the second reinforcing members 124 on the friction pad 105 during braking, thereby improving the overall structural stability of the caliper body 10.

[0150] In one embodiment, each of the two connections includes a reinforcement 12, wherein the reinforcement 12 at the connection for fixing the mounting base 111 of the brake motor 103 has a smaller external dimension than the other reinforcement 12.

[0151] like Figure 4As shown, the bent section 122 of the first reinforcing member 123 is used to be embedded at the connection between the first mounting base 1111 and the connecting bridge 112, and the bent section of the second reinforcing member 124 is used to be embedded at the connection between the second mounting base 1112 and the connecting bridge 112. The length of the extension section 121 of the first reinforcing member 123 is less than the length of the extension section 121 of the second reinforcing member 124, that is, the overall size of the first reinforcing member 123 is smaller than the overall size of the second reinforcing member 124. Because the first mounting base 1111 is used to fix the brake motor 103, its structural stability is relatively good. Increasing the volume of the second reinforcing member 124 at the second mounting base 1112 can improve the structural stability of the second mounting base 1112.

[0152] In one embodiment, the reinforcement 12 is embedded in the main structure 11 by welding, gluing, integral casting, or interference fit.

[0153] In one embodiment, the surface of the reinforcement 12 that is used to fit against the main structure 11 includes a plurality of protrusions 107 or a plurality of grooves 106. The reinforcement 12 and the main structure 11 have a large contact area, and the tightness of the connection between the reinforcement 12 and the main structure can be improved when the reinforcement 12 is embedded into the main structure 11 by welding, gluing or integral casting.

[0154] Please see Figure 16 This is a schematic diagram showing another exploded structure of the clamp 10 provided in one embodiment of the present application.

[0155] like Figure 16 As shown, the reinforcement 12 includes a plurality of protrusions 107 located on the surface of each extension 121 facing the main structure 11. The second surface 1122 of the connecting bridge 112 and the fourth surface 1114 of the second mounting base 1112 both include a plurality of grooves 106 for accommodating the protrusions 107. The reinforcement 12 is fitted to the main structure 11 such that each protrusion 107 of the reinforcement 12 extends into a groove 106, increasing the contact area between the reinforcement 12 and the main structure 11, resulting in a tighter fit and ensuring reliable embedding of the reinforcement 12 within the main structure 11.

[0156] In one embodiment, the reinforcement 12 includes a plurality of grooves 106, and the main structure 11 includes a plurality of protrusions 107. The reinforcement 12 is fitted to the main structure 11 such that each protrusion 107 of the main structure 11 extends into a groove 106, which also increases the contact area between the reinforcement 12 and the main structure 11, making the fit between the reinforcement 12 and the main structure 11 tighter, thereby ensuring that the reinforcement 12 is reliably embedded in the main structure 11.

[0157] In one embodiment, the main structure 11 includes a groove 106 for accommodating a reinforcement member 12, the spacing between the groove walls of the groove 106 being less than the width of the reinforcement member 12, and the reinforcement member 12 being used to form a dense layer on the groove walls of the groove 106, the density of the dense layer being greater than the density of the rest of the main structure 11.

[0158] Please see Figure 17 This is a schematic diagram showing another exploded structure of the clamp 10 provided in one embodiment of the present application.

[0159] like Figure 17 As shown, the main structure 11 includes four grooves 106 for accommodating the reinforcement 12. For ease of description, in subsequent embodiments, the groove 106 located at the connection between the connecting bridge 112 and the first mounting base 1111 is defined as the first groove 1061, and the groove 106 located at the connection between the connecting bridge 112 and the second mounting base 1112 is defined as the second groove 1062. That is, the main structure includes a pair of first grooves 1061 and a pair of second grooves 1062.

[0160] The clamp body 10 includes a pair of first reinforcing members 123 and a pair of second reinforcing members 124. Each first reinforcing member 123 is used to be embedded in a first groove 1061, and each second reinforcing member 124 is used to be embedded in a second groove 1062. Each groove 106 includes a pair of opposing groove walls, the distance between the pair of groove walls being less than the width of the reinforcing member 12. After the reinforcing member 12 is embedded in the groove 106, it forms an interference fit with the main structure 11, and the groove walls of the groove 106 form a dense layer.

[0161] The first reinforcement member 123 is in close contact with the dense layer of the groove wall of the first groove 1061, ensuring that the first reinforcement member 123 is in close contact with the connecting bridge 112 and the first mounting base 1111. The second reinforcement member 124 is in close contact with the dense layer of the groove wall of the second groove 1062, ensuring that the second reinforcement member 124 is in close contact with the second mounting base 1112.

[0162] Please see Figure 18 This is a schematic diagram showing another exploded structure of the clamp 10 provided in one embodiment of the present application.

[0163] like Figure 18As shown, the main structure 11 includes a groove 106 for accommodating the reinforcement member 12. The clamp body 10 includes a reinforcement member 12. After being embedded in the groove 106, the reinforcement member 12 can also form an interference fit with the main structure 11, resulting in a dense layer on the groove wall of the groove 106. The reinforcement member 12 fits snugly against the dense layer to ensure a tight fit between the reinforcement member 12 and the main structure 11. Furthermore, the reinforcement member 12 is connected to two bent sections 122 by an extension section 121, which increases the contact area between the reinforcement member 12 and the dense layer, thereby improving the reliability of the connection between the reinforcement member 12 and the main structure 11.

[0164] In one embodiment, along the arrangement direction of the two mounting seats 111, the two opposite sides of the two mounting seats 111 are configured as a pair of groove walls of the groove 106. The reinforcement 12 is embedded between the two mounting seats 111, and each mounting seat 111 is used to fix an extension 121 of the reinforcement 12. The reinforcement 12 also includes an extension 121 extending along the length direction of the connecting bridge 112.

[0165] Please see Figure 19 This is a schematic cross-sectional view of the main structure 11 provided in one embodiment of this application.

[0166] like Figure 19 As shown, the main structure 11 forms a U-shaped groove 106 through the first mounting base 1111, the connecting bridge 112, and the second mounting base 1112. The two facing surfaces of the first mounting base 1111 and the second mounting base 1112 are constructed as a pair of groove walls of the groove 106, and the connecting bridge 112 is constructed as the bottom of the groove 106.

[0167] Please combine Figure 10 and Figure 11 Along the arrangement direction of the two mounting seats 111, the distance between the two opposing surfaces of the two extensions 121 embedded in the two mounting seats 111 is greater than the distance between the two facing surfaces of the first mounting seat 1111 and the second mounting seat 1112, so that the reinforcement 12 forms an interference fit with the main structure 11, and both the first mounting seat 1111 and the second mounting seat 1112 form a dense layer. The two extensions 121 of the reinforcement 12 are used to fit against the dense layers of the first mounting seat 1111 and the second mounting seat 1112 respectively, so as to ensure that the reinforcement 12 fits tightly against the main structure 11.

[0168] In one embodiment, the clamp 10 further includes a positioning pin 108, which is used to embed into the main structure 11 and at least partially fit the reinforcement 12, and the positioning pin 108 is used to limit the relative displacement between the reinforcement 12 and the main structure 11.

[0169] Please see Figure 20This is a schematic cross-sectional view of a clamp 10 provided in one embodiment of the present application.

[0170] like Figure 20 As shown, the reinforcing member 12 and the main structure 11 each include a notch. The reinforcing member 12 is embedded in the main structure 11, such that the notch of the reinforcing member 12 and the notch of the main structure 11 are joined to form a positioning hole. The positioning pin 108 is located in the positioning hole and is respectively abutted against the inner surface of the notch of the main structure 11 and the inner surface of the notch of the reinforcing member 12. The clamp 10 restricts the reinforcing member 12 within the main structure 11 through the positioning pin 108, preventing the reinforcing member 12 from shifting relative to the main structure 11.

[0171] In one embodiment, a mounting base 111 is used to mount the brake motor 103 and the friction plate 105, and a locating pin 108 is located in another mounting base 111.

[0172] like Figure 10 As shown, the locating pin 108 is located at the contact point between the second mounting base 1112 and the reinforcing member 12. Because the first mounting base 1111 is equipped with the brake motor 103, it has a larger volume and relatively better structural stability. The second mounting base 1112 has a relatively smaller volume, relatively poorer structural stability, and is prone to deformation. By using the locating pin 108 to better hold the reinforcing member 12 within the second mounting base 1112, the structural stability of the second mounting base 1112 can be improved.

[0173] In one embodiment, the two mounting bases 111 are arranged in a direction parallel to the axial direction of the brake motor 103.

[0174] like Figure 3 As shown, the axial direction of the motor shaft 1031 of the brake motor 103 is parallel to the arrangement direction of the two mounting seats 111, so that the brake motor 103 can drive the first friction plate 1051 to slide axially and contact the brake disc 201 to form friction. After the first friction plate 1051 contacts the brake disc 201, it also facilitates the brake motor 103 to drive the clamp body 10 to slide axially, so that the second friction plate 1052 follows the clamp body 10 to slide and contact the brake disc 201 to form friction. That is, the axial direction of the motor shaft 1031 is parallel to the arrangement direction of the two mounting seats 111, which facilitates the brake motor 103 to drive the first friction plate 1051 and the second friction plate 1052 to slide axially and brake the brake disc 201, thereby improving the braking efficiency of the electromechanical braking device 100 provided in this application.

[0175] In one embodiment, the mounting base 111 for fixing the brake motor 103 includes two lugs 102, which are arranged on both sides of the mounting base 111 along the width direction of the friction pad 105. The electromechanical braking device 100 also includes two slide rods, one end of each slide rod is fixed to the caliper frame 120, and the other end passes through one lug 102 and is slidably connected to the lug 102, so that the lug 102 can slide relative to the caliper frame 120 along the slide rod. During braking, the caliper body 10 slides relative to the caliper frame 120 through the two lugs 102 and drives the other friction pad 105 to move towards the brake disc 201.

[0176] like Figure 1 and Figure 2 As shown, the two lugs 102 are slidably connected to the caliper bracket 120. Please refer to... Figure 3 During braking, the brake motor 103 drives the caliper body 10 to slide relative to the caliper bracket 120, and drives the second friction pad 1052 to move toward the brake disc 201, so that the second friction pad 1052 comes into contact with the brake disc 201 to form friction force, thereby braking the vehicle 200.

[0177] 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.
