[0002] The vehicle's dashboard is a key interface for drivers to obtain information about the vehicle's operating status. It provides drivers with necessary operating data and warning information through various instruments, indicator lights, and displays.

[0003] In related technologies, instrument panels are usually rigidly connected to the vehicle body during installation without a vibration damping structure. When the vehicle experiences severe vibrations during driving, it can easily cause damage to the instrument panel housing or malfunction of internal electronic components. Utility Model Content

[0004] In order to at least address some of the shortcomings mentioned in the related technologies, this application provides a vibration damping device and a vehicle.

[0005] To achieve the above objectives, a vibration damping device is provided for damping the dashboard of a vehicle, comprising a bracket and a damping assembly. The bracket is disposed between the vehicle body and the dashboard, connecting the vehicle and the dashboard. The damping assembly includes at least two damping pads, and the dashboard is mounted to the vehicle body via the bracket. Each damping pad includes a first damping portion and a second damping portion, with a connecting portion between the first and second damping portions. The connecting portion has a groove, the first damping portion abuts against the dashboard, and the bracket is mounted on the connecting portion.

[0006] Furthermore, a through hole is provided at the center of the vibration damping pad, and a mounting post is provided on the instrument panel, which is inserted into the through hole.

[0007] Furthermore, the groove of the connecting portion is provided in a direction perpendicular to the through hole, and the groove is located away from the instrument panel.

[0008] Furthermore, the first vibration damping part is configured as an annular shape, and a gap is provided between the inner wall of the first vibration damping part and the mounting column.

[0009] Furthermore, the mounting post has a threaded hole, and the screw is threadedly installed in the threaded hole. The end of the screw can abut against the second damping part of the damping pad to restrict the damping pad to the mounting post.

[0010] Furthermore, a washer is provided between the screw and the mounting post, and the washer is pressed against the second vibration damping part.

[0011] Furthermore, the bracket has a connecting hole that engages with the groove in the connecting portion. When the screw secures the vibration damping pad to the mounting post, the side of the groove presses against the bracket.

[0012] Furthermore, the edge of the bracket is raised towards the dashboard, and the raised part of the bracket is located on the bracket near the vibration damping pad.

[0013] Furthermore, the instrument panel includes a first housing and a second housing, which are detachably joined to form a mounting cavity. A seal is also provided at the joint between the first housing and the second housing.

[0014] This application also provides a vehicle, including a vehicle body, an instrument panel, and a vibration damping device as described in any of the above embodiments. The vibration damping device is disposed between the vehicle body and the instrument panel, and is used to connect the instrument panel and provide vibration damping for the instrument panel.

[0015] Through the above technical solution, the vibration damping device of this application is installed between the vehicle body and the dashboard. During vehicle operation, the vibration generated by the vehicle body is transmitted to the dashboard through the bracket. At this time, since the bracket is installed in the groove, and the groove is located between the first vibration damping part and the second vibration damping part, the vibration damping pad will reduce the vibration transmitted from the vehicle body to the dashboard through the bracket, thus protecting the dashboard.

[0016] The first vibration damping unit is located between the bracket and the dashboard, directly blocking vibration and providing protection. The second vibration damping unit reduces the vibration transmitted from the vehicle body to the bracket, which in turn reduces the vibration transmitted to the dashboard, further improving the protection capability of this embodiment.

[0027] This embodiment provides a vibration damping device to solve the problem in related technologies where a rigid connection between the dashboard and the vehicle leads to easy damage.

[0028] Please see Figures 1 to 3A vibration damping device for use on a vehicle to dampen the vibration of an instrument panel 300 includes a bracket 100 and a vibration damping assembly. The bracket 100 is disposed between the vehicle body and the instrument panel 300 for connecting the vehicle and the instrument panel 300. The vibration damping assembly includes at least two damping pads 200, and the instrument panel 300 is mounted on the vehicle body via the bracket 100. The damping pads 200 include a first damping portion 210 and a second damping portion 220, and a connecting portion 230 is provided between the first damping portion 210 and the second damping portion 220. The connecting portion 230 has a groove, the first damping portion 210 abuts against the instrument panel 300, and the bracket 100 is mounted on the connecting portion 230.

[0029] Specifically, in this embodiment, the vibration damping device is used by placing the first damping part 210 of the damping pad 200 against the instrument panel 300, and then installing the bracket 100 into the groove on the connecting part 230 of the damping pad 200. The instrument panel 300 is mounted on the vehicle body via the bracket 100. Since the bracket 100 is installed in the groove, that is, the connection point between the bracket 100 and the instrument panel 300 is located between the first damping part 210 and the second damping part 220, after the vibration of the vehicle body is transmitted to the damping pad 200 through the bracket 100, it will be weakened by the cooperation of the first damping part 210 and the second damping part 220, thereby reducing the impact of the vibration transmitted by the vehicle body on the instrument panel 300.

[0030] In particular, the first damping part 210 is also located between the bracket 100 and the instrument panel 300. The vibration transmitted from the vehicle body to the bracket 100 is further reduced by the first damping part 210 during the process of being transmitted to the instrument panel 300, thereby protecting the instrument panel 300 and ensuring the performance of the instrument panel 300.

[0031] In one embodiment, exemplarily, such as Figures 1 to 3 As shown, a through hole is provided at the center of the vibration damping pad 200, and a mounting post 321 is provided on the instrument panel 300, which is inserted into the through hole. By inserting the mounting post 321 on the instrument panel 300 into the through hole of the vibration damping pad 200, a stable connection between the instrument panel 300 and the vibration damping device can be ensured, preventing the instrument panel 300 from shifting or loosening due to vibration during vehicle operation.

[0032] Furthermore, the mounting post 321 facilitates precise alignment between the instrument panel 300 and the vehicle body during installation. The design of the through-hole and mounting post 321 provides a mechanical guiding mechanism, making the assembly process simpler and more accurate, and avoiding installation errors.

[0033] Furthermore, since the mounting post 321 is inserted into the through hole of the damping pad 200, rather than being directly fixed to the bracket 100, this can mitigate the vibration transmitted from the vehicle body to the instrument panel 300 to a certain extent. This is because the vibration needs to be filtered by the material of the damping pad 200 before reaching the instrument panel 300, further weakening the impact of the vibration.

[0034] In one embodiment, exemplarily, such as Figure 3 As shown, the groove of the connecting part 230 is arranged perpendicular to the through hole, and the groove is located away from the instrument panel 300. This arrangement of the groove allows for a more reasonable positioning of the bracket 100 between the first damping part 210 and the second damping part 220 when it is mounted on the damping pad 200. Because the groove is located away from the instrument panel 300, vibrations transmitted from the vehicle body need to travel a longer path through the first damping part 210 to reach the bracket 100, thus increasing the chance of vibration absorption and attenuation, further optimizing the damping effect.

[0035] The grooves, positioned perpendicular to the through-holes, enhance the mechanical stability of the entire damping assembly. This layout prevents structural damage caused by lateral or longitudinal forces generated during vehicle operation acting directly on the through-holes, thus improving the overall durability and reliability of the device.

[0036] By moving the groove away from the instrument panel 300 and providing a thicker damping material, namely the first damping part 210, between the bracket 100 and the instrument panel 300, the instrument panel 300 can be provided with additional protection to a certain extent. This prevents damage caused by external impacts or prolonged vibrations when the vehicle is traveling on bumpy roads for a long time, ensuring the working performance and service life of the instrument panel 300.

[0037] It is understandable that multiple grooves can be provided on the connecting portion 230 of the damping pad 200 according to actual needs. The design of multiple grooves can be flexibly adjusted according to different installation requirements and vehicle vibration characteristics. For example, the damping effect can be optimized by selecting grooves of different positions or depths to adapt to vibration sources of different types or intensities. Providing multiple grooves increases the selectivity and flexibility of the bracket 100 during installation. This allows for the selection of the most suitable mounting point for a specific vehicle model or dashboard 300 design, contributing to more precise alignment and a more stable installation.

[0038] Please continue reading. Figure 3For example, the first damping part 210 is configured as an annular shape, and a gap is provided between the inner wall of the first damping part 210 and the mounting post 321. The annular first damping part 210 can provide a uniform damping effect in all directions. Due to the gap inside, this means that the mounting post 321 will not directly contact the inner wall of the first damping part 210, thereby avoiding the direct transmission of vibration caused by hard contact, and further enhancing the protection of the instrument panel 300.

[0039] The gap allows the first damping unit 210 to have some elastic deformation space, which allows for a small relative displacement between the first damping unit 210 and the mounting post 321 when the vehicle experiences vibration or impact. This design helps absorb additional energy, reduces the impact of vibration on the instrument panel 300, and also reduces stress concentration problems that may be caused by rigid connections.

[0040] In one embodiment, exemplarily, such as Figure 2 As shown, the mounting post 321 has a threaded hole, and a screw is threaded into the hole. The end of the screw abuts against the second damping part 220 of the damping pad 200, thus securing the damping pad 200 to the mounting post 321. Fixing the damping pad 200 to the mounting post 321 with screws ensures that the damping pad 200 will not shift or fall off due to vibrations during vehicle operation. The screws provide additional mechanical fixation for the damping device, enhancing the overall structural stability.

[0041] Since the end of the screw directly abuts against the second damping part 220, the pressure on the second damping part 220 can be changed by adjusting the screw's screwing depth, thereby fine-tuning the overall damping performance of the damping pad 200. This allows for cost-effective optimization and adjustment of the damping effect based on actual conditions to achieve the best damping performance.

[0042] Meanwhile, by confining the vibration damping pad 200 to the mounting post 321, misalignment or damage to the vibration damping pad 200 due to external factors such as accidental collisions or strong vibrations is avoided. This design also prevents the vibration damping pad 200 from loosening or failing due to long-term use, thus extending its service life.

[0043] Please continue reading. Figure 2For example, a washer 240 is also provided between the screw and the mounting post 321, and the washer 240 presses against the second damping part 220. The presence of the washer 240 helps to evenly distribute the pressure applied by the screw to the second damping part 220. In other words, the washer 240 increases the contact area between the screw tip and the second damping part 220, thereby reducing the pressure per unit area, reducing the risk of material damage caused by excessive pressure concentration, preventing damage or deformation of the damping material due to excessive local pressure, and ensuring that the damping assembly can work effectively for a long time.

[0044] Using shim 240 can prevent screws from loosening to some extent. Especially when the vehicle experiences vibration and impact during operation, the additional friction provided by shim 240 helps to keep the screws tight, thereby ensuring the safety and stability of the connection.

[0045] It should be noted that the number of vibration damping pads 200 can be set according to actual needs. In this embodiment, three vibration damping pads 200 are provided. Setting three vibration damping pads 200 can evenly distribute the weight and vibration energy of the instrument panel 300 across multiple support points. This distribution method can prevent a single vibration damping pad 200 from bearing excessive pressure or vibration impact, thereby extending the service life of the vibration damping pad 200. Multi-point support can also reduce local stress concentration and lower the risk of material fatigue due to long-term use.

[0046] Multiple damping pads 200 work together to absorb and attenuate vibration energy at different locations. Compared to one or two damping pads 200, three damping pads 200 can cover a larger area, providing more comprehensive vibration protection. Moreover, each damping pad 200 can be optimized for vibrations in a specific direction or frequency, thereby further improving the overall vibration reduction performance.

[0047] In one embodiment, exemplarily, such as Figure 2 As shown, the bracket 100 has a connecting hole that engages with the groove in the connecting part 230. When the screw secures the damping pad 200 to the mounting post 321, the side of the groove presses against the bracket 100. This arrangement ensures a tight connection between the bracket 100 and the damping assembly, reducing loosening or displacement caused by vibrations during vehicle operation. The pressure of the groove side against the bracket 100 increases the friction and contact area between the two, thereby enhancing the stability and robustness of the overall structure.

[0048] In this way, vibrations transmitted from the vehicle body can be more effectively absorbed by the first damping part 210 and the second damping part 220. The pressing contact between the side of the groove and the bracket 100 helps to directly guide vibration energy into the damping pad 200, rather than concentrating it at a certain point. This helps to optimize the distribution path of vibration energy and improve the damping effect.

[0049] The design of the connecting hole snapping into the groove makes assembly more intuitive and simple. Quick installation can be achieved without complex alignment or adjustment, improving work efficiency. Furthermore, this design facilitates subsequent maintenance and disassembly. And when the screws secure the vibration damping pad 200 to the mounting post 321, the side of the groove presses against the bracket 100, providing a locking effect and preventing accidental detachment or failure due to vibration. This provides an additional guarantee for the safe operation of the entire system.

[0050] In one embodiment, exemplarily, such as Figure 1 , Figure 3 As shown, the edge of the bracket 100 curves upwards towards the instrument panel 300, and the curved portion 110 of the bracket 100 is located on the bracket 100 near the vibration damping pad 200. The curved portion at the edge of the bracket 100 can provide additional physical protection for the instrument panel 300 to a certain extent. For example, in the event of a minor collision or impact from a foreign object, the curved portion can act as a first line of defense, reducing direct damage to the instrument panel 300. The curved design increases the structural complexity and rigidity of the bracket 100, improving its resistance to deformation. Especially under external forces, this design can better maintain shape stability and prevent fatigue damage caused by long-term vibration.

[0051] In one embodiment, exemplarily, such as Figure 1 As shown, the instrument panel 300 includes a first housing 310 and a second housing 320, which are detachably joined to form a mounting cavity. A seal 350 is also provided at the joint between the first housing 310 and the second housing 320. The mounting post 321 is located on the second housing 320. Designing the instrument panel 300 as two or more detachable housings makes the internal electronic components and wiring easier to access, facilitating inspection, repair, or replacement. This design greatly improves maintenance efficiency and reduces maintenance costs and time. The seal 350 at the joint effectively prevents moisture, dust, and other impurities from entering the instrument panel 300, protecting the internal precision electronic components from damage and ensuring the reliability and durability of the instrument panel 300 under various environmental conditions.

[0052] Of course, a display panel 330 is also provided on the side of the first housing 310 away from the second housing 320 to cover the window on the first housing 310. A display screen 340 and a circuit board 360 are provided between the first housing 310 and the second housing 320. The display screen 340 and the circuit board 360 are electrically connected, and the display screen 340 is installed at the window of the first housing 310.

[0053] The display panel 330 not only displays information but also effectively shields the window on the first housing 310, protecting the display screen 340 and internal circuitry from dust, moisture, and other contaminants. This is crucial for ensuring the long-term stable operation of the instrument panel 300. Placing the display screen 340 and circuit board 360 within the space between the first housing 310 and the second housing 320 achieves a compact design layout. This allows for the integration of more functions within a limited space while ensuring that the overall dimensions of the instrument panel 300 meet the design requirements of the vehicle's interior.

[0054] This embodiment also provides a vehicle, including a vehicle body, an instrument panel 300, and a vibration damping device as described in any of the above embodiments. The vibration damping device is disposed between the vehicle body and the instrument panel 300, and is used to connect the instrument panel 300 and provide vibration damping for the instrument panel 300.
