Description

Technical Field

[0001] This application relates to the technical field of human-computer interaction devices, and in particular to a folding vehicle-mounted human-computer interaction device. Background Technology

[0002] With the intelligent upgrading of the automotive industry, human-machine interaction devices, as the core hub for communication between drivers or passengers and vehicle information systems, are widely used in complex working scenarios such as new energy off-road vehicles, mobile command vehicles, armored vehicles and engineering machinery. In order to adapt to the limited space layout inside the vehicle and take into account the convenience of operation and screen protection requirements, human-machine interaction devices usually adopt a foldable structure design.

[0003] Currently, common human-computer interaction devices mainly consist of a display interaction panel and a host processing base. The display interaction panel integrates a high-definition display screen, touch unit, and mechanical buttons, while the host processing base integrates a core data processing motherboard, power filtering module, and various data interfaces. The display interaction panel and the host processing base are connected by a mechanical hinge, thereby realizing the functions of unfolding for interaction and closing for storage.

[0004] When installing and deploying existing human-computer interaction devices, the host processing base is usually installed on the vehicle frame using bolt connections. In order to mitigate the vibration caused by vehicle movement, in addition to thickening the host processing base shell and filling it with cushioning foam, the industry often also uses solid rubber washers at the bolt connections for cushioning.

[0005] However, when installing human-machine interface devices onto the vehicle frame, installers often tighten the bolts excessively to prevent the devices from falling off during severe vehicle vibrations. This causes the rubber gaskets to be under extremely high compression, resulting in a loss of elasticity and an inability to effectively filter vibrations during vehicle operation. This failure in damping will directly transmit vibration energy to the inside of the human-machine interface device, damaging its internal electronic components and severely affecting its reliability and lifespan. Summary of the Invention

[0006] This application provides a folding vehicle-mounted human-machine interaction device, the purpose of which is to enhance the shock absorption capability of the human-machine interaction device, thereby improving the shock resistance performance of the human-machine interaction device during vehicle operation, and further improving the reliability and service life of the human-machine interaction device.

[0007] The foldable vehicle-mounted human-computer interaction device provided in this application adopts the following technical solution: A folding vehicle-mounted human-machine interface device includes a display interaction panel; a host processing base rotatably connected to the display interaction panel; a fixed plate frame, parallel and spaced apart from the host processing base, with the host processing base and the display interaction panel located on the same side of the fixed plate frame; a mounting component on the fixed plate frame for mounting the fixed plate frame to a vehicle body bracket; and a suspension damping assembly including a connecting bolt, a connecting nut screwed onto the connecting bolt, a bushing sleeve coaxially sleeved on the outside of the connecting bolt, and two elastic rings coaxially sleeved on the outside of the bushing sleeve; a first hole penetrating the fixed plate frame, and a second hole opening on the host processing base; the connecting bolt being inserted into the first hole and the second hole; the nut of the connecting bolt, the fixed plate frame, one elastic ring, the host processing base, the other elastic ring, and the connecting nut being sequentially arranged along the axial direction of the connecting bolt; the bushing sleeve being inserted into the second hole, with its axial ends abutting against the fixed plate frame and the connecting nut, respectively.

[0008] By adopting the above technical solution, the suspension damping component uses connecting bolts and connecting nuts to connect the fixed plate frame to the main unit processing base, thereby fixing the fixed plate frame to the main unit processing base. This allows the human-machine interaction device to be installed on the vehicle body bracket through the mounting parts on the fixed plate frame, thus meeting the installation requirements of the human-machine interaction device.

[0009] Based on this, since two elastic rings are provided on the connecting bolts, and the fixed plate frame, one elastic ring, the main unit processing base, the other elastic ring, and the connecting nut are arranged sequentially along the axial direction of the connecting bolts, the fixed plate frame, the main unit processing base, and the connecting nut can be damped and isolated by the two elastic rings, thereby reducing the vibration transmitted from the vehicle body to the main unit processing base.

[0010] Since the connecting bolt is fitted with a bushing, and the two ends of the bushing abut against the fixed plate frame and the connecting nut respectively, when the connecting nut is tightened, the connecting nut and the fixed plate frame are separated by the bushing and form a fixed axial distance. This distance directly limits the installation space of the two elastic rings.

[0011] Therefore, regardless of the tightening force applied by the connecting nut, the tightening load is primarily borne by the rigid bushing. This forcibly limits the compression of the elastic ring, ensuring it is compressed only within a preset compression ratio range. This design effectively prevents the elastic ring from losing its elastic deformation capacity due to excessive compression, ensuring it always maintains sufficient elastic travel to absorb vibrations generated during vehicle operation. This improves the damping failure phenomenon caused by overly tight connecting nuts. This enhances the vibration damping capability of the human-machine interface device, thereby improving its anti-vibration performance during vehicle operation, and ultimately increasing its reliability and service life.

[0012] Optionally, a plurality of first ribs are provided on both sides of the elastic ring along the axial direction. The length direction of the first ribs is arranged along the corresponding radial direction of the elastic ring. The plurality of first ribs located on the same side of the elastic ring along the axial direction are arranged sequentially at intervals along the circumference of the connecting bolt. The first ribs are integrally formed with the elastic ring. The side of the first rib away from the corresponding elastic ring abuts against the corresponding fixed plate frame, the main unit processing base, or the connecting nut.

[0013] By adopting the above technical solution, the elastic ring reduces its initial contact area by having several first ribs abut against the corresponding contact surfaces. This reduces the stiffness of the elastic ring in the initial stage of stress. When the human-machine interface device is subjected to micro-amplitude high-frequency vibrations, the first ribs can more easily undergo shear deformation, thereby improving the filtering capability of micro-amplitude high-frequency vibrations. Simultaneously, because adjacent first ribs are spaced apart, when the elastic ring is compressed and deformed, the gap between adjacent first ribs not only provides space for expansion and deformation but also forms a heat dissipation channel for air circulation. Therefore, during vibration, air can flow within the gap between adjacent first ribs to carry away the heat generated by repeated deformation of the elastic ring, preventing the elastic ring from aging rapidly due to heat accumulation, thus enhancing the durability and stability of the elastic ring.

[0014] Optionally, an elastic tube is coaxially sleeved on the outside of the bushing tube, and the elastic tube is coaxially inserted into the second hole.

[0015] By adopting the above technical solution, the elastic tube is placed between the bushing tube and the second hole wall of the main unit processing base, which plays a physical isolation role. When the vehicle experiences horizontal swaying or sudden braking, the elastic tube can absorb energy through its own shear deformation, preventing a hard collision between the main unit processing base and the bushing tube, thereby enhancing the protection capability of the human-machine interface device against lateral impacts. Therefore, the suspension damping component not only uses two elastic rings to buffer vertical impacts, but also uses the middle elastic tube to buffer horizontal shear forces, thus achieving multi-dimensional flexible damping.

[0016] Optionally, the inner and outer walls of the elastic tube are provided with a plurality of second ribs, the length direction of the second ribs is arranged along the axial direction of the elastic tube, and the plurality of second ribs located on the inner or outer side of the elastic tube are arranged sequentially at intervals along the circumference of the elastic tube; the second ribs are integrally formed with the elastic tube, and the side of the second rib away from the elastic tube abuts against the inner wall of the corresponding bushing or the second hole.

[0017] By adopting the above technical solution, the second rib on the elastic tube can reduce the contact area between the elastic tube and the inner wall of the second hole and the outer wall of the bushing, thereby reducing the frictional resistance during assembly and facilitating the installation of the elastic tube. Simultaneously, the gap between two adjacent second ribs allows airflow, which helps dissipate heat from the elastic tube, thus ensuring its durability and stability.

[0018] Optionally, the host processing base is provided with a locking component on the side facing the display interaction panel, the locking component being used to lock the display interaction panel.

[0019] By adopting the above technical solution, when the human-computer interaction device is in the storage state, the locking component can form a rigid lock between the display interaction panel and the host processing base. This can limit the degree of freedom of the display interaction panel and prevent the display interaction panel from opening and closing uncontrollably during severe vehicle bumps, thereby improving the structural safety of the human-computer interaction device under harsh road conditions.

[0020] Optionally, the host processing base includes a base housing, and the display interaction panel is rotatably connected to the base housing; a support substrate is disposed inside the base housing, a buffer cavity is disposed inside the host processing base, the support substrate is located inside the buffer cavity, and a buffer assembly is filled between the inner wall of the buffer cavity and the outer wall of the support substrate; a clearance hole is provided through the base housing, and a second hole is opened on the support substrate and is located inside the clearance hole; the connecting bolt is located inside the clearance hole, and the nut of the connecting bolt, the fixing plate frame, one elastic ring, the support substrate, another elastic ring, and the connecting nut are arranged sequentially along the axial direction of the connecting bolt.

[0021] By adopting the above technical solution, the host processing base achieves a rotatable connection with the actual interactive panel through the setting of the base shell.

[0022] Based on this, a support plate is installed inside the base housing, and the suspension damping component is directly connected to the support plate. This allows the fixed plate frame and the support plate to be connected through the suspension damping component. At the same time, the support plate is suspended in the buffer cavity, and the space between the outer wall of the support plate and the inner wall of the buffer cavity is filled with the buffer component.

[0023] With this structural design, the vibration from the vehicle body is first transmitted to the suspension damping component in the vibration transmission path. After being initially filtered by the two layers of elastic rings in the suspension damping component, it is transmitted to the bearing plate, causing the bearing plate to float relatively in the buffer cavity. Subsequently, the floating displacement of the bearing plate squeezes the buffer component, and the buffer component uses material damping to transmit the attenuated vibration to the housing of the main unit processing base.

[0024] Therefore, this design achieves physical isolation and graded treatment of vibration reduction. Vibration energy must undergo two attenuation processes—the elastic deformation energy dissipation of the suspension damping component and the damping energy dissipation of the buffer component—before it can be transmitted to the main unit's processing base. This step-by-step attenuation mechanism can more thoroughly isolate external severe vibrations and residual micro-vibrations, thereby improving the stability of the main unit's processing base.

[0025] Optionally, the buffer assembly includes two layers of buffer pads, with the supporting substrate located between the two layers of buffer pads. The supporting substrate and the two layers of buffer pads are stacked sequentially along the axial direction of the connecting bolt, and the buffer pads are away from the supporting substrate and abut against the inner wall of the buffer cavity.

[0026] By adopting the above technical solution, the buffer assembly clamps the supporting substrate with two layers of buffer pads. When the supporting substrate is subjected to vertical vibration transmitted from the suspension damping assembly, the supporting substrate floats up and down, pressing against the corresponding buffer pads. At this time, the two layers of buffer pads absorb the vibration energy through compression deformation. Therefore, this sandwich structure not only further reduces the residual vibration energy in the vertical direction, but also plays a flexible limiting role, restricting the displacement range of the supporting substrate within the buffer cavity.

[0027] Optionally, the buffer assembly further includes a buffer ring located between the two layers of buffer pads, with the carrier substrate located inside the buffer ring, the inner sidewall of the buffer ring abutting against the outer sidewall of the carrier substrate, and the outer sidewall of the buffer ring abutting against the inner sidewall of the buffer cavity.

[0028] By employing the above technical solution, a buffer ring is filled around the periphery of the supporting substrate. When a vehicle experiences sudden braking or sharp turning, resulting in a lateral impact, the supporting substrate will compress the buffer ring in the horizontal direction. Therefore, the buffer ring absorbs the horizontal shear vibration energy through its own compressive deformation and flexibly restricts the horizontal displacement of the supporting substrate.

[0029] Optionally, the buffer pad has slender ribs on both sides, the length of the slender ribs is along the length of the buffer pad, and the slender ribs on the same side of the buffer pad are spaced apart in sequence along their width direction; the slender ribs are integrally formed with the corresponding buffer pad, and the side of the slender rib away from the corresponding buffer pad abuts against the corresponding support substrate or the inner sidewall of the buffer cavity; the inner sidewall of the buffer cavity is provided with a plurality of heat dissipation holes.

[0030] By adopting the above technical solution, the slender ribs on the buffer pad change the contact method between the buffer pad and the corresponding contact surface from surface contact to line contact. This reduces the dynamic stiffness of the buffer pad during the initial compression stage, making it more sensitive to high-frequency micro-vibrations. Simultaneously, when the human-machine interface device vibrates, the slight floating of the supporting substrate squeezes the air between adjacent slender ribs, generating a pumping effect that drives airflow. Therefore, this design achieves a synergistic effect of structural vibration reduction and active heat dissipation, effectively improving the heat dissipation environment within the enclosed buffer cavity and preventing fatigue aging of the buffer pad due to heat accumulation.

[0031] Optionally, the substrate is provided with a plurality of material removal slots, which are arranged at uniform intervals along the circumference of the second hole, and are arranged in a ring. The material removal slots are located outside the clearance hole.

[0032] By adopting the above technical solution, a material removal groove is formed around the second hole on the carrier substrate, creating a strip-shaped metal cantilever between two adjacent material removal grooves. Based on this, when encountering high-frequency micro-vibrations, the metal cantilever can undergo slight elastic bending due to the low hysteresis and high sensitivity of the metal material. Therefore, this design allows the carrier substrate to respond instantly and filter out high-frequency micro-vibrations, achieving precise protection for highly sensitive components within the host processing base, thereby further improving the full-band vibration resistance of the human-machine interface device.

[0033] In summary, this application includes at least one of the following beneficial technical effects: 1. This application utilizes the cooperation between the axle sleeve and the elastic ring in the suspension damping component. By leveraging the rigid limiting effect of the axle sleeve, it ensures that the elastic ring is not excessively compressed when the connecting nut is tightened, thus keeping the elastic ring within the optimal elastic travel range. This ensures that the elastic ring always has sufficient elastic travel to absorb vibrations generated during vehicle operation, thereby enhancing the shock absorption capability of the human-machine interface device, improving its anti-vibration performance during vehicle operation, and ultimately increasing its reliability and service life.

[0034] 2. This application uses the design of the first rib on the elastic ring. This structure reduces the contact area between the elastic ring and the corresponding contact surface, thereby reducing the stiffness of the elastic ring in the initial stage of stress. When the human-computer interaction device is subjected to micro-amplitude high-frequency vibration, the first rib can more easily undergo shear deformation, thereby improving the filtering ability of micro-amplitude high-frequency vibration.

[0035] 3. This application utilizes the elastic tube, which, by employing its own shear deformation characteristics, can specifically buffer the horizontal shear force generated during sudden braking, turning, or tilting of a vehicle.

[0036] 4. This application, through the cooperation of the suspension damping component, the supporting base plate, and the buffer component, ensures that vibration energy must undergo two attenuation processes—the elastic deformation energy dissipation of the suspension damping component and the damping energy dissipation of the buffer component—before it is transmitted to the interior of the host processing base. This step-by-step attenuation mechanism can more thoroughly isolate external severe vibrations and residual micro-vibrations, thereby improving the stability of the host processing base.

[0050] The following is in conjunction with the appendix Figure 1 -Appendix Figure 12 This application will be described in further detail below.

[0051] Example 1: A folding vehicle-mounted human-computer interaction device, referring to... Figure 1 and Figure 2 The system includes a display and interaction panel 1 and a host processing base 2. The host processing base 2 is horizontally positioned, and the display and interaction panel 1 is located below the host processing base 2. One side of the display and interaction panel 1 is rotatably connected to the host processing base 2, and a locking assembly 3 is provided on the host processing base 2. A fixed plate frame 4 is horizontally positioned above the host processing base 2, and several mounting parts 41 are provided on the fixed plate frame 4. Several floating shock-absorbing components 5 are provided between the fixed plate frame 4 and the host processing base 2.

[0052] Reference Figure 1The interactive display panel 1 includes a panel housing 11, on which a touch screen 12 and a button panel 13 are mounted. The button panel 13 has several mechanical buttons. The touch screen 12 is embedded in the front of the panel housing 11, and the button panel 13 is located around the touch screen 12. The touch screen 12 serves as the primary information output and interaction window for human-computer interaction, while the mechanical buttons provide a physical input method with clear tactile feedback to meet different operational needs than the touch screen 12.

[0053] Reference Figure 1 and Figure 2 The host processing base 2 includes a base housing 21 and an electronic control component 22 built into the base housing 21. The electronic control component 22 includes at least a controller, a power supply module, and a hard disk. The controller is electrically connected to the touch screen 12 and several mechanical buttons, which enables the controller to process instructions from the display interaction panel 1. The power supply module is electrically connected to the controller and can be connected to the vehicle power supply system to supply power to the controller. The hard disk is electrically connected to the controller, which enables the hard disk to store all data.

[0054] In addition, refer to Figure 1 Various data interfaces are provided on the side wall of the base housing 21, such as aviation plug interface, USB debugging interface and power interface. All data interfaces are electrically connected to the controller, which enables the electrical connection between the human-machine interaction device and the vehicle.

[0055] Reference Figure 1 and Figure 2 The base housing 21 is horizontally arranged, the panel housing 11 is vertically arranged, and the panel housing 11 is located below the base housing 21. The upper side of the panel housing 11 is rotatably connected to the base housing 21.

[0056] In this embodiment, refer to Figure 3 and Figure 4 The panel housing 11 and the base housing 21 are rotatably connected via a damping shaft. Because the damping shaft provides a constant rotational damping force, the panel housing 11 can be infinitely adjusted and hovered, allowing the interactive display panel 1 to be infinitely adjusted and hovered between its folded / closed position and any unfolded angle.

[0057] In this embodiment, refer to Figure 3 and Figure 4An angle detection sensor is provided inside the base housing 21 or at the rotatable connection between the base housing 21 and the panel housing 11. The angle detection sensor adopts a Hall sensor or a magnetic switch. The angle detection sensor is electrically connected to the controller. Through this angle detection sensor, the tilting angle of the display interaction panel 1 relative to the host processing base 2 can be monitored in real time, and the signal is transmitted to the controller. This signal can be used as the basis for the controller to determine whether to switch between driving mode and parking mode.

[0058] Specifically, the controller has pre-set driving mode and parking mode logic. When the angle detection sensor detects that the display interaction panel 1 is not fully closed but has not reached the preset stable locking angle, or when the controller receives a signal that the vehicle is in motion, the controller controls the human-machine interface device to enter driving mode. In driving mode, to prevent accidental touches due to vehicle bumps, the controller will block non-core touch areas on the touch screen 12 (e.g., only retaining the core function areas with large icons such as navigation and call), or block the input signals of some mechanical buttons, retaining only the response of core function buttons (such as mute, power, and emergency call), thereby ensuring the safety and accuracy of operation during driving. When the angle detection sensor detects that the display interaction panel 1 is fully extended and locked, or when the controller receives a signal that the vehicle is stationary, the controller controls the device to enter parking mode. In parking mode, the controller releases the blocking of the touch screen 12 and mechanical buttons, opening all interactive functions, allowing users to perform complex data queries, system settings, or multimedia entertainment operations, thereby improving the convenience of operation and interactive experience.

[0059] Reference Figure 4 and Figure 5 The locking assembly 3 includes an operation button 32 and a mechanical locking tongue 33. An operation groove 31 is formed on the side wall of the base housing 21. The operation button 32 is slidably installed in the operation groove 31, and the operation button 32 slides against the inner wall of the operation groove 31, so that the operation button 32 can only perform reciprocating linear motion in the horizontal direction. An operation spring 34 is provided between the inner end face of the operation button 32 and the bottom of the operation groove 31. One end of the operation spring 34 abuts against the bottom of the operation groove 31, and the other end abuts against the operation button 32, so that the operation spring 34 can apply an outward restoring elastic force to the operation button 32.

[0060] Reference Figure 5The base housing 21 has a locking tongue groove 35 at one end facing the panel housing 11. The locking tongue groove 35 communicates with the operation groove 31, and the mechanical locking tongue 33 is located in the locking tongue groove 35. The mechanical locking tongue 33 is arranged vertically, with one end fixedly connected to the operation button 32 and the other end extending out of the locking tongue groove 35. Thus, when the operation button 32 moves horizontally in the operation groove 31, the operation button 32 can drive the mechanical locking tongue 33 to move synchronously horizontally in the corresponding locking tongue groove 35.

[0061] Reference Figure 5 The panel housing 11 has a snap-fit ​​groove 36 on the side facing the base housing 21. When the panel housing 11 is rotated to close in the direction of the base housing 21, the snap-fit ​​groove 36 and the locking tongue groove 35 are directly connected and the mechanical locking tongue 33 is engaged with the corresponding snap-fit ​​groove 36.

[0062] Reference Figure 5 In this embodiment, in order to achieve smooth closing and locking, a guide slope 37 is provided on the corresponding end of the mechanical locking tongue 33 and / or the edge of the inner wall of the latch groove 36.

[0063] Reference Figure 5 With the design of the locking assembly 3, when the display interaction panel 1 is folded closed, the edge of the panel housing 11 first contacts the guide slope 37 of the mechanical locking tongue 33. As the closing force is applied, the mechanical locking tongue 33 is pushed inward, causing the operation button 32 to overcome the resistance of the operation spring 34 and retract into the operation groove 31. When the display interaction panel 1 is fully closed, the mechanical locking tongue 33 aligns with the latching groove 36. Under the elastic force of the operation spring 34, the operation button 32 drives the mechanical locking tongue 33 to quickly reset and pop out, inserting into the latching groove 36 to achieve a locking engagement. At this time, the display interaction panel 1 and the main unit processing base 2 are rigidly locked and cannot be unfolded on their own. With this design, the display interaction panel 1 can be closed and locked during vehicle bumps, thereby effectively limiting the degree of freedom of the display interaction panel 1 and protecting it from physical damage.

[0064] Reference Figure 1 and Figure 6 Several suspension damping components 5 are provided, and the several suspension damping components 5 are arranged in a matrix between the fixed plate frame 4 and the base shell 21. In this embodiment, four suspension damping components 5 are provided.

[0065] Reference Figure 6 and Figure 7The suspension damping component 5 includes a connecting bolt 51, a connecting nut 52, a bushing 53, and two elastic rings 54. The connecting bolt 51 is arranged vertically, the bushing 53 is coaxially sleeved on the outside of the connecting bolt 51, the two elastic rings 54 are coaxially sleeved on the outside of the bushing 53, and the two elastic rings 54 are spaced apart along the axial direction of the bushing 53. The connecting nut 52 is sleeved on the connecting bolt 51, and the connecting bolt 51 and the connecting nut 52 are screwed together.

[0066] Along the axial direction of the connecting bolt 51, the bushing 53 and the two elastic rings 54 are located between the nut and the connecting nut 52 of the connecting bolt 51.

[0067] Reference Figure 6 and Figure 7 A number of first holes 42 are provided through the fixed plate frame 4, and a number of second holes 214 are provided through the base shell 21. The first holes 42 and the second holes 214 are provided in a one-to-one correspondence, and the first holes 42 and the corresponding second holes 214 are coaxially connected.

[0068] Reference Figure 6 and Figure 7 The first hole 42 is correspondingly provided with the connecting bolt 51, and the connecting bolt 51 is coaxially inserted into the first hole 42 and the corresponding second hole 214. Furthermore, the nut of the connecting bolt 51, the fixed plate bracket 4, one elastic ring 54, the base housing 21, another elastic ring 54, and the connecting nut 52 are sequentially arranged along the axial direction of the connecting bolt 51. The bushing 53 is coaxially inserted into the second hole 214, and the bushing 53 is located between the connecting nut 52 and the fixed plate bracket 4 along its own axial direction. One end of the bushing 53 abuts against the connecting nut 52, and the other end abuts against the fixed plate bracket 4.

[0069] Based on the structural design of the suspension damping component 5, after the suspension damping component 5 is installed on the fixed plate frame 4 and the base housing 21, when the connecting nut 52 is tightened, the two axial ends of the bushing 53 form rigid contact with the fixed plate frame 4 and the connecting nut 52 respectively. At this time, the locking force applied by the connecting nut 52 is mainly borne by the rigid bushing 53. This can prevent the connecting nut 52 from driving the two elastic rings 54 to compress excessively, so that the two elastic rings 54 are always within the preset compression ratio range, avoiding the elastic rings 54 from being over-compressed and losing their elastic stroke, thereby ensuring the stability of the buffering performance of the suspension damping component 5 in long-term use.

[0070] Reference Figure 6 and Figure 7In this embodiment, an elastic tube 55 is coaxially sleeved on the outside of the bushing 53. The elastic tube 55 is coaxially inserted into the second hole 214, and is located between the outer wall of the bushing 53 and the hole wall of the second hole 214. The upper end of the elastic tube 55 is inserted into an elastic ring 54, and the upper end of the elastic tube 55 is spaced apart from the inner wall of the elastic ring 54, and the upper end of the elastic tube 55 is spaced apart from the fixed plate frame 4. The lower end of the elastic tube 55 is connected to another elastic ring 54, and the elastic tube 55 and the elastic ring 54 are integrally formed.

[0071] Since the elastic tube 55 is located between the outer wall of the bushing 53 and the wall of the second hole 214, it can provide physical isolation, preventing the base housing 21 from making direct hard contact with the metal bushing 53, thereby cutting off the rigid transmission path of vibration. This allows the suspension damping assembly 5 to not only buffer vertical impacts using the upper and lower elastic rings 54, but also buffer horizontal shear forces using the middle elastic tube 55, achieving multi-dimensional flexible damping.

[0072] Reference Figure 7 In this embodiment, a plurality of first ribs 541 are provided on both sides of the elastic ring 54. The first ribs 541 are integrally formed with the corresponding elastic ring 54. The length direction of the first ribs 541 is arranged along the corresponding radial direction of the elastic ring 54. A plurality of first ribs 541 located on the same side of the elastic ring 54 are arranged sequentially at intervals along the circumference of the connecting bolt 51.

[0073] Reference Figure 6 and Figure 7 The side of the first rib 541 away from the corresponding elastic ring 54 abuts against the lower side wall of the corresponding fixed plate frame 4, or the upper or lower side wall of the corresponding base shell 21, or the upper side wall of the connecting bolt 51.

[0074] With the design of several first ribs 541, this structure reduces the initial stiffness of the elastic ring 54, making the elastic ring 54 more prone to shear deformation when subjected to high-frequency micro-amplitude vibration, thereby improving the filtering ability of the elastic ring 54 to high-frequency micro-amplitude vibration. At the same time, the gap between the first ribs 541 also provides deformation space for the rubber to expand under pressure, extending its service life.

[0075] Furthermore, since the two adjacent first ribs 541 are spaced apart, a heat dissipation groove can be formed between the two adjacent ribs. This heat dissipation groove design increases the contact area between the surface of the elastic ring 54 and the air. Because the elastic ring 54 generates internal heat due to repeated compression and deformation during shock absorption, the heat dissipation groove can utilize the micro-airflow generated by the vibration to carry away this heat, preventing the elastic ring 54 from aging prematurely due to heat accumulation and further ensuring the durability of the elastic ring 54.

[0076] Reference Figure 7The inner and outer walls of the elastic tube 55 are provided with a number of second ribs 551. The second ribs 551 are integrally formed with the elastic tube 55. The length direction of the second ribs 551 is arranged along the axial direction of the elastic tube 55. The number of second ribs 551 located on the inner or outer side of the elastic tube 55 are arranged sequentially at intervals along the circumference of the elastic tube 55.

[0077] Reference Figure 6 and Figure 7 The side of the second rib 551 away from the elastic tube 55 abuts against the outer wall of the corresponding bushing 53 or the inner wall of the second hole 214.

[0078] The design of the second rib 551 reduces the contact area between the elastic tube 55, the bushing tube 53, and the inner wall of the second hole 214, thereby reducing frictional resistance during installation and facilitating installation. Simultaneously, the vertical second rib 551 allows for slight tilting in multiple directions when subjected to horizontal shear force, further softening the horizontal stiffness and preventing rigid collisions between the base housing 21 and the bushing tube 53 under conditions such as sudden braking.

[0079] Similarly, heat dissipation grooves can also be formed between two adjacent second ribs 551, which also assists in the heat dissipation of the elastic tube 55.

[0080] Reference Figure 6 and Figure 7 In this embodiment, the suspension damping assembly 5 further includes an extension ring 56, which is coaxially sleeved on the outside of the connecting bolt 51. The extension ring 56 is located between the connecting nut 52 and the bushing 53 along the axial direction of the connecting bolt 51. One side of the extension ring 56 abuts against the bushing 53, and the other side abuts against the connecting nut 52. The outer diameter of the extension ring 56 is larger than the outer diameter of the connecting nut 52. Several first ribs 541 located on the lower side of the bottom elastic ring 54 abut against the extension ring 56.

[0081] Therefore, the extension ring 56, as a rigid washer, can transmit the locking force of the connecting nut 52 to the bushing 53 on the one hand, and on the other hand, due to its large outer diameter, it can serve as a support base for the lower elastic ring 54, ensuring that the elastic ring 54 is subjected to uniform force.

[0082] Reference Figure 2 and Figure 6 In this embodiment, the base housing 21 includes a front shell 212 and a back plate 211. The back plate 211 is horizontally arranged and serves as the main load-bearing component, with a second hole 214 penetrating through it. The front shell 212 is located below the back plate 211, and is fastened to the back plate 211 and connected by bolts, forming a closed cavity 213 between the front shell 212 and the back plate 211. The electronic control component 22 is located within this closed cavity 213 and fixed to the front shell 212.

[0083] When installing the suspension damping assembly 5 on the base housing 21, first remove the back plate 211 from the front housing 212. Then, insert the corresponding elastic ring 54 between the fixed plate frame 4 and the back plate 211. Subsequently, insert the connecting bolt 51, and install the bushing 53, another elastic ring 54, a corresponding elastic tube 55, an extension ring 56, and a connecting nut 52 in sequence on the side of the back plate 211 away from the fixed plate frame 4, and finally tighten the connecting nut 52. Finally, reinstall the back plate 211 onto the front housing 212. At this time, the edge of the second hole 214 on the back plate 211 is firmly clamped between the upper and lower elastic rings 54, that is, the back plate 211 is completely suspended.

[0084] Reference Figure 1 and Figure 6 The fixed plate frame 4 is horizontally positioned directly above the back panel 211, and several mounting components 41 are provided on the fixed plate frame 4. The mounting components 41 are bolts or welded studs. The fixed plate frame 4 can be installed onto a bracket inside the vehicle body through the mounting components 41, thereby fixing the human-machine interaction device.

[0085] Reference Figure 6 In this embodiment, a clearance through hole 215 is provided through the base housing 21, which penetrates the front shell 212 and the back plate 211. The clearance through hole 215 is provided in a one-to-one correspondence with the mounting member 41, and the mounting member 41 is located in the corresponding clearance through hole 215. The opening of the clearance through hole 215 prevents the base housing 21 from interfering with the installation of the fixed plate frame 4.

[0086] In this embodiment, the elastic ring 54 and the elastic tube 55 can be made of high-damping silicone or EPDM rubber to obtain excellent weather resistance and shock absorption performance; the connecting bolt 51 is a countersunk bolt or an internal hex bolt, and the connecting bolt 51 and the bushing 53 can be made of stainless steel or heat-treated carbon steel to ensure structural strength; the expansion ring 56 and the fixed plate frame 4 can be made of aluminum alloy or cold-rolled steel plate to balance lightweight and load-bearing capacity.

[0087] The implementation principle of this embodiment is as follows: During vehicle operation, when encountering vertical road bumps, the two elastic rings 54 mainly absorb impact energy through axial compression deformation. Among them, the first rib 541 on the elastic ring 54 deforms first, providing a lower initial stiffness to filter out minor road noise. As the compression increases, the main body of the elastic ring 54 intervenes to bear a larger load, thereby achieving a gradual buffer from micro-vibrations to large impacts.

[0088] When the vehicle experiences horizontal swaying or sudden braking, the elastic tube 55 undergoes shear deformation. At this time, by utilizing the characteristic of the rubber material having low stiffness in the shear direction, the rigid transmission path in the horizontal direction and the transmission of high-frequency vibration are effectively cut off, thereby achieving flexible shock absorption.

[0089] Example 2: A folding vehicle-mounted human-computer interaction device, referring to... Figure 8 and Figure 9 The difference between this embodiment and embodiment 1 is that the base housing 21 also includes a suspended housing 216 and a supporting substrate 217. The suspended housing 216 is located between the back plate 211 and the front shell 212, and the back plate 211, the suspended housing 216 and the front shell 212 are connected by bolts.

[0090] Reference Figure 8 and 9 A buffer cavity is provided inside the suspended shell 216, the supporting base plate 217 is located in the buffer cavity, and the outer wall of the supporting base plate 217 is spaced apart from the inner wall of the buffer cavity. A buffer component 6 is filled between the outer wall of the supporting base plate 217 and the inner wall of the buffer cavity. The suspension shock absorption component 5 is disposed between the supporting base plate 217 and the fixed plate frame 4, and the suspended shell 216 and the back plate 211 are spaced apart from the suspension shock absorption component 5.

[0091] Under this design, the fixed plate frame 4 is connected to the bearing base plate 217 through several suspension damping components 5, and a buffer component 6 is provided between the bearing base plate 217 and the suspension shell 216. The suspension shell 216 is connected to the back plate 211 and the front shell 212. This means that the vibration of the vehicle body needs to be buffered twice by the suspension damping components 5 and the buffer component 6 before it can be transmitted to the main processing base 2.

[0092] Reference Figure 9 and Figure 10 In this embodiment, a plurality of second holes 214 are formed on the supporting substrate 217, and a plurality of clearance holes 2111 are formed on the back plate 211. The clearance holes 2111 penetrate the suspended shell 216. The clearance holes 2111 and the second holes 214 are arranged in a one-to-one correspondence. The second holes 214 are located in the clearance holes 2111, and the suspension shock absorption component 5 is located in the corresponding clearance hole 2111.

[0093] Specifically, the connecting bolts 51, bushings 53, and elastic tubes 55 in the suspension damping assembly 5 are all inserted into the corresponding second holes 214 on the bearing base plate 217, and the bearing base plate 217 is located between the two elastic rings 54.

[0094] Reference Figure 10 and Figure 11 The buffer assembly 6 includes two buffer pads 61, and the supporting substrate 217 is located between the two buffer pads 61. The supporting substrate 217 and the two buffer pads 61 are stacked sequentially along the axial direction of the connecting bolt 51. The buffer pads 61 are away from the supporting substrate 217 and abut against the inner wall of the buffer cavity.

[0095] Based on the arrangement of the buffer pads 61, the two layers of buffer pads 61 can further reduce the vibration energy transmitted to the bearing substrate 217 through the suspension damping component 5, thereby achieving the second-level damping function.

[0096] Reference Figure 9 and Figure 11 In this embodiment, the buffer pad 61 is provided with a plurality of staggered holes 611, and the staggered holes 611 are provided in a one-to-one correspondence with the second hole 214. The second hole 214 is located in the corresponding staggered hole 611, and the staggered hole 611 is the same as the corresponding clearance hole 2111.

[0097] Reference Figure 9 and Figure 11 In this embodiment, the buffer pad 61 is provided with a plurality of slender ribs 612 on both sides along the axial direction of the connecting bolt 51. The length direction of the slender ribs 612 is along the length direction of the buffer pad 61, and the plurality of slender ribs 612 on the same side of the buffer pad 61 are arranged at intervals along their own width direction. The slender ribs 612 are integrally formed with the corresponding buffer pad 61, and the side of the slender rib 612 away from the corresponding buffer pad 61 abuts against the corresponding supporting base plate 217 or the inner sidewall of the buffer cavity. The suspension shell 216 is provided with a plurality of heat dissipation holes on its periphery.

[0098] Based on the arrangement of the slender ribs 612, the surface contact between the buffer pad 61 and the contact surface is transformed into a line contact. This structural change reduces the dynamic stiffness of the buffer assembly 6 during the initial compression stage, making it more sensitive to high-frequency micro-vibrations. Simultaneously, the gaps between the slender ribs 612 provide ample deformation space for the expansion of the buffer pad 61 under pressure, preventing fatigue aging of the material due to excessive compression. More importantly, the spaced slender ribs 612 form airflow channels. When the human-machine interface device vibrates, the slight movement of the supporting substrate 217 relative to the suspended housing 216 drives airflow within the channels, expelling the hot air generated by internal material friction through the heat dissipation holes on the suspended housing 216. Active heat dissipation is achieved through the pumping effect generated by vibration.

[0099] Reference Figure 11 The buffer assembly 6 also includes a buffer ring 62, which is located between two buffer pads 61, and the carrier substrate 217 is located inside the buffer ring 62. The inner sidewall of the buffer ring 62 abuts against the outer sidewall of the carrier substrate 217, and the outer sidewall of the buffer ring 62 abuts against the inner sidewall of the buffer cavity.

[0100] Based on the buffer ring 62, when the vehicle brakes suddenly or turns sharply and generates horizontal shear force, the bearing plate 217 will squeeze the buffer ring 62. The buffer ring 62 absorbs the lateral impact energy through compression deformation, limiting the maximum displacement of the bearing plate 217 in the horizontal direction and preventing rigid collision between the internal fixed plate frame 4 and the suspended shell 216.

[0101] In this embodiment, both the buffer pad 61 and the buffer ring 62 are made of high-damping PORON cotton (polyurethane foam) or thermally conductive silicone pads. The carrier substrate 217 is made of aluminum-magnesium alloy plate or stainless steel plate.

[0102] The implementation principle of this application embodiment is as follows: On the vibration transmission path, the vibration from the vehicle body is first transmitted to the suspension damping assembly 5 by the fixed plate frame 4. During this process, the connecting bolt 51, together with two elastic rings 54 and elastic tubes 55, absorbs most of the impact energy by utilizing the compression and shear deformation of the elastic material, thereby achieving the first stage of damping and converting the severe vehicle body vibration into a relatively gentle floating of the bearing plate 217.

[0103] Subsequently, the floating displacement of the support substrate 217 will compress the buffer pad 61 and the buffer ring 62. The buffer pad 61 and the buffer ring 62 utilize the high damping characteristics of the material to further dissipate the residual vibration energy and flexibly limit the displacement range of the support substrate 217, thereby achieving the second stage of vibration reduction.

[0104] Finally, the weak vibration, after being attenuated twice, is transmitted to the base housing 21.

[0105] This series-type dual-stage damping mechanism ensures that even under extreme off-road conditions, the electronic control components 22 inside the main unit processing base 2 can remain in a relatively stable environment, thereby enabling the human-machine interface device to operate stably for a long time.

[0106] Example 3: A folding vehicle-mounted human-computer interaction device, referring to... Figure 12 The difference between this embodiment and embodiment 2 is that: in the area where the supporting substrate 217 is connected to the suspension damping component 5, that is, the periphery of the second hole 214, a plurality of material removal slots 2171 are opened through by laser cutting or stamping process. The plurality of material removal slots 2171 are arranged evenly at intervals along the circumference of the corresponding second hole 214, and the plurality of material removal slots 2171 are arranged in a ring. A strip-shaped metal cantilever strip 2172 is formed between two adjacent material removal slots 2171. The material removal slots 2171 are located outside the corresponding avoidance hole 2111.

[0107] Based on the formation of the metal cantilever strip 2172, when the support substrate 217 is subjected to vertical vibration impact, the metal cantilever strip 2172 will bend relative to the main body of the support substrate 217, thereby absorbing minor vibrations.

[0108] Reference Figure 11 and Figure 12In this embodiment, a plurality of elastic filling layers are provided on the side of the buffer pad 61 facing the supporting substrate 217. The elastic filling layers are integrally formed with the corresponding buffer pad 61, and the elastic filling layers are provided one-to-one with the material removal grooves 2171, with the elastic filling layers located within the corresponding material removal grooves 2171. The elastic filling layers on the two buffer pads 61 are provided one-to-one, and the two corresponding elastic filling layers are located within the same corresponding material removal groove 2171, and the two elastic filling layers abut against each other.

[0109] The implementation principle of this application embodiment is as follows: When the human-computer interaction device encounters high-frequency micro-vibration, such as road noise during vehicle operation or high-frequency whistling of motor, the metal cantilever strip 2172 on the support substrate 217 undergoes a slight elastic bending. Utilizing the high sensitivity and low hysteresis physical characteristics of metal materials, the metal cantilever strip 2172 can respond to these micro-vibrations instantly, thereby achieving fine protection for highly sensitive components such as hard drives in the electronic control component 22.

[0110] When the load-bearing base plate 217 experiences excessive impact, such as when a vehicle passes over a speed bump or encounters severe vibrations, the metal cantilever bar 2172 tends to undergo significant bending deformation. At this time, the two buffer pads 61 and the elastic filler layer are compressed, thus providing strong counter-support to the metal cantilever bar 2172. The buffer pads 61 and the elastic filler layer act as limits for the metal cantilever bar 2172, preventing excessive bending and fatigue fracture due to exceeding the yield strength, thereby effectively improving the structural lifespan of the metal cantilever bar 2172.

[0111] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
