Description

Technical Field

[0001] This utility model relates to the field of automotive braking system technology, and in particular to a mounting bracket and an automobile. Background Technology

[0002] To ensure braking system safety, some vehicle models have an auxiliary motor installed next to the main brake motor. During vehicle operation, the auxiliary motor controls the front wheel braking, while the main motor controls the rear wheel braking. If either motor malfunctions, brake fluid is injected into the other motor through the brake lines, ensuring braking continues even if one motor fails. If the two motors are too far apart, the brake fluid travels a longer distance in the brake lines, reducing braking response and affecting safety. If the two motors are too close, the vibrations generated by the auxiliary motor are difficult to control and can easily resonate with the main motor, producing noise and affecting ride comfort. Utility Model Content

[0003] The purpose of this utility model is to provide a mounting bracket for mounting a motor, which can achieve double buffering and vibration reduction, thereby improving the vibration reduction effect and reducing vibration noise.

During installation, the connecting column passes through the snap-fit ​​holes, and the first damping part and the second damping part abut against the opposite sides of the mounting plate.

[0009] Optionally, the connecting column is provided with mounting holes for fasteners to pass through along its central axis; during installation, the fasteners pass through the mounting holes and are fixedly connected to the vehicle body.

[0010] Optionally, the second damping unit has a limiting part on the side away from the first damping unit, and the limiting part limits the relative movement between the two by increasing the friction between the first damping pad and the vehicle body.

These illustrative expressions do not necessarily refer to the same embodiment, nor are they independent or alternative embodiments mutually exclusive with other embodiments. Where there is no conflict, the embodiments and features described in these embodiments can be combined in a suitable manner.

[0029] Please see Figure 1 and Figure 2 This utility model provides a mounting bracket 2 for mounting motor 1 (see...) Figure 4 The motor 1 is installed on the vehicle body. The mounting bracket 2 includes a support plate 21 and a mounting plate 22. The motor 1 is mounted on the support plate 21, and the support plate 21 is fixed to the vehicle body by the mounting plate 22. The mounting plate 22 is integrally formed with the support plate 21, or the mounting plate 22 is fixedly connected to the support plate 21 by welding, riveting or fastener connection.

[0030] The mounting plates are at least two in number and are located around the periphery of the support plate. In one embodiment disclosed in this application, the mounting plate 22 includes a first mounting plate 221, a second mounting plate 222, and a third mounting plate 223. Specifically, the first mounting plate 221 and the second mounting plate 222 are respectively located on opposite sides of the support plate 21, and the first mounting plate 221 and the second mounting plate 222 are respectively bent upward at a certain angle along the corresponding side of the support plate 21 to adapt to and connect with the corresponding front bulkhead assembly 51 and front wheel arch 53 of the vehicle. The third mounting plate 223 is located on one side of the second mounting plate 222 and on the lower surface of the support plate 21 to adapt to and connect with its corresponding front longitudinal beam 52 of the vehicle. The mounting bracket 2 fixes the support plate 21 to the vehicle body through the three mounting plates 22, which helps to distribute the load and improve the stability and reliability of the connection. It should be noted that the mounting bracket 2 of this utility model does not limit the number of mounting plates 22. In other embodiments, the number of mounting plates 22 is two or more.

[0031] The support plate 21 is provided with a fixing plate 23 for fixed connection with the motor 1. Specifically, the support plate 21 is bent upward from its edge along the height direction of the vehicle to form the fixing plate 23, or a portion of the support plate 21 is punched and folded upward to form the fixing plate 23. In one embodiment, there are two fixing plates 23, which are spaced apart on the upper side of the support plate 21. The fixing plate 23 is provided with a mounting groove 231 for fasteners to pass through. The motor 1 is fixedly connected to the fixing plate 23 by fasteners, thereby improving the connection stability.

[0032] In one embodiment, a reinforcing rib 25 is provided on the first mounting plate 221. A portion of the first mounting plate 221 is recessed or protruding relative to another portion to form the reinforcing rib 25. The reinforcing rib 25 is linear. Specifically, the reinforcing rib 25 extends from the connection point between the first mounting plate 221 and the support plate 21 in a direction away from the support plate 21. The reinforcing rib 25 can increase the rigidity of the bracket, thereby improving the stability and reliability of the installation. Furthermore, when the auxiliary motor 12 is running, the reinforcing rib 25 can disperse vibration stress. In this embodiment, the edge of the support plate 21 is provided with a flange 26 to enhance structural strength and bending resistance. In other embodiments, the edge of the mounting plate 22 is provided with a flange 26. Therefore, this application is not limited, and flanges can be provided on the edges of at least one of the support plate 21 and the mounting plate 22.

[0033] In some embodiments, a vibration damping component 3 is mounted on the mounting bracket 2. The vibration damping component 3 is made of elastic materials such as rubber or polyurethane. Optionally, the vibration damping component 3 is fixedly connected to the mounting bracket 2 by means of snap-fit, interference fit, or other methods. Please refer to [link to relevant documentation]. Figure 1 and Figure 5The vibration damping assembly 3 includes a first damping pad 31 and a second damping pad 32. The first damping pad 31 is at least partially sandwiched between the mounting plate 22 of the mounting bracket 2 and the vehicle body, and the second damping pad 32 is at least partially sandwiched between the support plate 21 of the mounting bracket 2 and the motor 1. During the operation of the motor 1, the first damping pad 31 and the second damping pad 32 achieve two-stage buffering and vibration damping of the motor 1, improving the overall vibration damping effect, thereby reducing the vibration transmitted from the motor 1 to the vehicle body through the mounting bracket 2, which helps to reduce the vibration noise of the entire vehicle and improve ride comfort.

[0034] Each of the first mounting plate 221, the second mounting plate 222, and the third mounting plate 223 is provided with a first shock-absorbing pad 31. Specifically, each of the first mounting plate 221, the second mounting plate 222, and the third mounting plate 223 has a snap-fit ​​hole. Each first shock-absorbing pad 31 passes through its corresponding snap-fit ​​hole and is fixedly connected to the mounting plate 22 by snap-fit, interference fit, or other means. The snap-fit ​​hole can be a closed circular hole, such as... Figure 1 As shown, optionally, the snap-fit ​​hole on the third mounting plate 223 is a non-closed U-shaped hole, that is, the snap-fit ​​hole on the third mounting plate 223 has an opening, and the width of the opening gradually increases in the direction away from the middle of the mounting groove 231, which is conducive to the first shock-absorbing pad 31 being snapped into the snap-fit ​​hole, thereby facilitating installation.

[0035] Please see Figure 2 and Figure 3In one embodiment, the first damping pad 31 includes a connecting post 3a. The connecting post 3a has a first damping portion 3b and a second damping portion 3c extending radially outward from its outer circumferential surface at both ends of the axial direction. An annular snap-fit ​​groove 3e is formed between the first damping portion 3b and the second damping portion 3c. The portion of the mounting plate 22 corresponding to the snap-fit ​​hole is snapped into the snap-fit ​​groove 3e. The connecting post 3a has a mounting hole 3d penetrating its upper and lower end faces along its central axis for fasteners to pass through. During installation, the first damping pad 31 is aligned and inserted into the snap-fit ​​hole of the mounting plate 22. Because the first damping pad 31 has a mounting hole 3d, the first damping portion 3b is more easily deformed under pressure. After passing through the snap-fit ​​hole, the first damping portion 3b recovers its elastic deformation. Since the radial dimensions of the first damping portion 3b and the second damping portion 3c are larger than the inner diameter of the snap-fit ​​hole, they are located on opposite sides of the mounting plate 22, thus achieving a fixed connection between the first damping pad 31 and the mounting bracket 2 via a snap-fit ​​method. The connecting post 3a passes through the snap-fit ​​hole, and the fastener passes through the mounting hole 3d and is fixedly connected to the vehicle body. In this embodiment, the fastener can be a bolt, screw, rivet, or stud, etc. Optionally, the fastener is a bolt. The vehicle body has a through hole corresponding to the mounting hole 3d, and a nut is fixedly installed on the vehicle body corresponding to the through hole by welding or riveting. The first damping pad 31 is snapped into the snap-fit ​​hole, and the bolt passes through the mounting hole 3d of the first damping pad 31 and is threadedly connected to the nut at the through hole, fixing the mounting bracket 2 to the vehicle body for easy installation and disassembly. The structure of the second damping pad 32 is roughly the same as that of the first damping pad 31, and will not be described again here. During installation, the fastener passes through the mounting hole 3d of the second damping pad 32 to fix the motor 1 to the support plate 21.

[0036] In one specific embodiment provided in this application, the first damping part 3b is frustum-shaped, and the outer diameter of the first damping part 3b gradually decreases along the direction away from the snap-fit ​​groove 3e. During installation, the outer peripheral surface of the frustum-shaped first damping part 3b plays a guiding role, which is conducive to the first damping part 3b passing through the mounting hole 3d, and facilitates quick installation.

[0037] The second damping part 3c has a limiting part 311 on the side away from the first damping part 3b. Optionally, the limiting part 311 is a serrated protrusion. The auxiliary motor 12 (such as...) Figure 5 (As shown) When vibration occurs during operation, the limiting part 311 increases the friction between the first damping pad 31 and the vehicle body, limiting the relative movement and displacement amplitude between them. This prevents the fasteners from loosening due to vibration, making the connection between the mounting bracket 2 and the vehicle body more secure, improving the reliability of the installation, and thus ensuring the stability and safety of the motor 1 during operation. In addition, a groove is formed between every two adjacent protrusions. This groove increases the buffer space between the mounting bracket 2 and the vehicle body, further improving the vibration damping performance of the mounting bracket 2.

[0038] Please continue reading. Figure 3 Optionally, the first damping pad 31 is provided with a mounting sleeve 33. In one embodiment, the mounting sleeve 33 includes a main body section 331 and a flange section 332. Specifically, the main body section 331 is a hollow cylinder, and the flange section 332 is formed by radially protruding from the circumferential surface of the main body section 331. Furthermore, the outer diameter of the flange section 332 is larger than the diameter of the mounting hole 3d of the first damping pad 31. During installation, the flange section 332 is sandwiched between the bolt and the first damping part 3b of the first damping pad 31 to prevent the bolt from contacting the first damping member 31 and to prevent the first damping pad 31 from wearing or undergoing uneven compression deformation due to friction. Furthermore, the main body section 331 passes through the mounting hole 3d of the first damping pad 31. The main body section 331 is provided with a guide hole along its axial direction for fasteners to pass through, which facilitates installation. In addition, when the first damping pad 31 is subjected to pressure, the main body section 331 helps to maintain the relative position between the mounting sleeve 33 and the first damping pad 31, thereby improving the stability of the installation.

[0039] Optionally, the mounting bracket 2 is provided with weight-reducing holes, which can reduce material usage and weight. Specifically, the support plate 21 has a first weight-reducing hole 241 in the area away from the fixing plate 23, and the third mounting plate 223 has a second weight-reducing hole 242 in the middle.

[0040] In some embodiments, the first mounting plate 221 is provided with a positioning hole 224 for the fixture to pass through. During manufacturing or assembly, the positioning hole 224 can provide a positioning reference and clamping fulcrum for the fixture, improve the machining accuracy of the mounting bracket 2, simplify the clamping process, and improve production efficiency.

[0041] Optionally, the mounting bracket 2 is provided with a wire harness through hole 27 for the wire harness to pass through and to guide the direction of the wire harness.

[0042] Please see Figure 4 and Figure 5This utility model also proposes a vehicle, including a front bulkhead assembly 51, a front longitudinal beam 52, a main motor 11, an auxiliary motor 12, and the aforementioned mounting bracket 2. The front bulkhead assembly 51 includes a front bulkhead plate 511 and a front bulkhead reinforcing beam 512. The main motor 11 is mounted on the front bulkhead plate 511. The auxiliary motor 12 is fixed to the vehicle body near the main motor 11 via the mounting bracket 2. Specifically, the auxiliary motor 12 is fixed to the support plate 21 of the mounting bracket 2. The first mounting plate 221, the second mounting plate 222, and the third mounting plate 223 of the mounting bracket 2 are respectively fixed to the front bulkhead reinforcing beam 512, the front longitudinal beam 52, and the front wheel arch 53. The mounting bracket 2 is positioned between the front bulkhead reinforcing beam 512 and the front longitudinal beam 52. In the event of a frontal collision, the front bulkhead assembly 51 can absorb some of the collision energy and transfer the remaining collision energy to the front longitudinal beam 52. The auxiliary motor 12, mounted via the mounting bracket 2 in the area between the front bulkhead assembly 51 and the front longitudinal beam 52, can reduce the risk of impact and improve safety.

[0043] Please see Figure 6 In some embodiments, the two motors 1 are connected by four connecting pipes 4. Under normal operating conditions, the main motor 11 controls the rear wheel braking, and the auxiliary motor 12 controls the front wheel braking. When one of the motors 1 fails, the brake fluid in one motor 1 flows to the other motor 1 through the connecting pipes 4 to ensure that the vehicle can still brake, thereby ensuring safety. In addition, the auxiliary motor 12 is positioned close to the main motor 11, which can shorten the power transmission path between the two motors 1, thereby improving response efficiency. At the same time, the vibration damping component 3 can reduce the vibration amplitude of the motor 1 during operation, effectively avoiding resonance caused by frequency coupling between the main motor 11 and the auxiliary motor 12, thereby reducing noise, improving ride comfort, and improving the overall NVH (noise, vibration, and harshness) performance of the vehicle.

[0044] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
