[0001] This utility model relates to the field of vibration reduction device technology, and in particular to a sway protection device for human-computer interaction equipment. Background Technology

[0002] In existing technologies, human-computer interaction devices such as in-vehicle displays and laptops are prone to severe vibrations when driving on bumpy roads, which obviously accelerates the damage to these devices. While fixing a portion of the human-computer interaction device in one place can improve its stability, it restricts its movement, making it difficult for the device to smoothly perform actions such as unfolding and retracting the display.

[0003] Therefore, how to improve the vibration resistance of human-computer interaction devices while ensuring their smooth operation has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a vibration protection device for human-computer interaction devices, so as to improve the vibration resistance of human-computer interaction devices while enabling them to move smoothly.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides a shake protection device for human-computer interaction devices, the shake protection device comprising:

[0007] A vibration damping component is connected to a human-machine interface device. The vibration damping component applies a first force to the human-machine interface device along a first direction to resist impacts and vibrations from the human-machine interface device in the opposite direction to the first direction.

[0008] An assistive component is connected to the human-computer interaction device. The assistive component can apply a second force to the human-computer interaction device. The second force is greater than the first force and the second force is in the same direction as the movement of the human-computer interaction device, thereby assisting in driving the human-computer interaction device to move.

[0009] Preferably, the vibration damping assembly includes a first damper, the damping of which is fixed.

[0010] And / or, the vibration damping component includes a first drive component, which is connected to the human-machine interaction device for driving the human-machine interaction device to move, and the first drive component is a shaft driver;

[0011] And / or, the vibration damping component includes a vibration damping pad disposed on the human-machine interaction device;

[0012] And / or, the vibration damping component includes a first support base and a first elastic element, with both ends of the first elastic element connected to the first support base and the human-machine interaction device, respectively.

[0013] Preferably, the sway protection device includes a second support base, on which the human-machine interface device is mounted, and on which a plurality of locking rods are mounted. The human-machine interface device is provided with a plurality of locking holes that cooperate with the locking rods; the locking rods and the locking holes constitute the vibration damping component.

[0014] Preferably, the vibration damping component includes an electromagnet and a ferromagnetic part, the electromagnet is disposed on a third support base, the human-machine interaction device is provided with a ferromagnetic part, and the human-machine interaction device is located on the third support base.

[0015] Preferably, the vibration damping component includes a fourth support base, on which the human-machine interface device is mounted. A fifth support base is located on the side of the fourth support base away from the human-machine interface device. Two connecting rods are located on the side of the fourth support base facing the fifth support base. The first end of each connecting rod is rotatably connected to the fourth support base, and the second end of each connecting rod is slidably connected to the fifth support base. A second elastic element is located between the second ends of the two connecting rods, and the two ends of the second elastic element are respectively connected to the second ends of the two connecting rods.

[0016] Preferably, the sway protection device further includes: a second drive component, the second drive component being drivenly connected to the human-machine interaction device, the assist component including a reducer, and the second drive component being drivenly connected to the human-machine interaction device through the reducer;

[0019] Preferably, both the vibration damping component and the assist component are connected to the controller signal.

[0020] The present invention achieves the following technical advantages over the prior art:

[0021] This invention applies a first force to the human-machine interface device along a first direction using a vibration damping component, resisting impacts and vibrations in the opposite direction to the first direction. This improves the stability of the human-machine interface device, making it less prone to shaking when traversing uneven surfaces, thus reducing vibration and damage caused by external shocks. However, it's important to note that the vibration damping component has two sides: while the first force suppresses vibration by improving stability, it also means that when the human-machine interface device is in motion, its relatively stable state under the first force also makes it less susceptible to damage. The tendency to move is inherent in human-computer interaction devices (HCIs). The initial force acts as a "resistance" during movement, making it difficult for the HCI to move smoothly, such as extending or retracting from a storage box. Therefore, this invention incorporates a support component that applies a second force, greater than the first force, along the direction of movement. This second force increases the HCI's momentum in the direction of movement, making its movement smoother. In short, this invention improves the vibration resistance of HCIs while ensuring smooth movement, greatly enhancing the user experience. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 , Figure 2 As shown, this utility model provides a sway protection device for a human-computer interaction device. The sway protection device includes: a vibration damping component 1, which is connected to the human-computer interaction device and can apply a first force to the human-computer interaction device in a first direction to resist the impact and vibration of the human-computer interaction device from the opposite direction of the first direction; and an assist component 2, which is connected to the human-computer interaction device and can apply a second force to the human-computer interaction device in the direction of movement of the human-computer interaction device, which is greater than the first force in the opposite direction, to assist the movement of the human-computer interaction device.

[0029] This invention utilizes the vibration damping component 1 to apply a first force to the human-computer interaction device, resisting the impact and vibration experienced by the device, thereby improving its stability. This makes the device less prone to shaking when traversing uneven surfaces, reducing vibration and damage caused by external shocks, lowering noise generated during movement, and enhancing the user experience. However, it's important to note that the vibration damping component 1 has two sides: while the first force can suppress vibration by improving stability, it also means that when the device moves, it is also subject to vibration under the first force. The first force acts as a "resistance" when the human-computer interaction device moves, making it difficult for the device to move smoothly, such as extending or retracting from the storage box. Therefore, this invention provides an assist component 2 to apply a second force, greater than the first force, along the direction of movement of the human-computer interaction device. This second force increases the power of the device in the direction of movement, making its movement smoother. In short, this invention improves the vibration resistance of the human-computer interaction device while ensuring its smooth movement, greatly enhancing the user experience.

[0030] For example, when a human-machine interface device is connected to a drive component, and the drive component is used to drive the human-machine interface device to rotate, the drive component can specifically be a rotary drive structure such as a rotary motor. In this case, the vibration damping component 1 can be a damper connected to the output shaft of the drive component. The damper can specifically be a hydraulic damper or a spring damper, etc. In this case, the damper can be set parallel to the output shaft of the drive component. The assist component 2 can be a gearbox, such as a gear reducer, connected to the output shaft of the drive component. In this way, when the human-machine interface device travels on a bumpy road surface, the damper can convert the vibration along the output shaft of the drive component into the movement of the hydraulic oil or spring inside it. The damper dissipates vibration energy, thereby suppressing the movement of the human-machine interface device along the output shaft of the drive component. Furthermore, the damper contacts the output shaft of the drive component, and a certain frictional force exists between the damper and the output shaft. This, to some extent, also suppresses the rotation of the human-machine interface device and its radial movement along the output shaft of the drive component, thus improving the vibration resistance of the human-machine interface device. Simultaneously, the gearbox increases the output force of the drive component's output shaft, making it greater than the aforementioned frictional force, allowing the drive component's output shaft to smoothly drive the human-machine interface device to rotate in the presence of the damper.

[0031] When the human-machine interface device is connected to the support base via an elastic element with buffering properties, such as a spring, the elastic element acts as a vibration damping component 1. The support base can be fixed to a vehicle or other structure. Thus, if the support base, elastic element, and human-machine interface device are arranged vertically from bottom to top, when the human-machine interface device experiences vertical vibration, the elastic element absorbs the vibration energy by converting the vibration into its own vertical deformation, reducing the vertical vibration of the human-machine interface device and improving its vibration resistance. In this case, the assist component 2 can specifically be an electric push rod, a pneumatic... A drive structure, such as a cylinder, can move a human-machine interface device vertically or horizontally. The output force of the drive structure is greater than the force exerted by the elastic element on the human-machine interface device. Depending on the direction of movement of the human-machine interface device, the drive structure can be set to move horizontally or vertically accordingly. Compared with the method of manually moving the human-machine interface device by the operator, the drive structure makes it easier for the human-machine interface device to move vertically or horizontally. Moreover, a gearbox can be connected to the output shaft of the drive structure to further enhance the output force of the drive structure, so that the human-machine interface device can move more smoothly.

[0032] Among them, human-computer interaction devices refer to devices such as displays, radios, and speakers that can output corresponding information after a person inputs information. For example, pressing a button on a radio or display will cause the radio to emit sound, or the display to switch images. Human-computer interaction devices can specifically be structures such as in-vehicle displays or laptops. When the human-computer interaction device is connected to the drive structure 3, the drive structure 3 can move the human-computer interaction device out of the storage box and retract it into the storage box. Depending on the working conditions, the drive structure 3 can specifically be a rotary motor or an electric push rod.

[0033] The vibration damping component 1 and the booster component 2 have multiple configuration options.

[0034] For example, the vibration damping component 1 includes a first damper with a fixed damping. The first damper can be directly connected to the human-machine interface device or to the drive structure 3 that drives the human-machine interface device. Through the energy absorption and release process of the first damper, it plays the role of damping shock and vibration. The first damper can be selected from existing dampers with fixed damping, which will not be elaborated here.

[0035] And / or, the vibration damping component 1 includes a first drive component, which is connected to the human-machine interface device for driving the human-machine interface device to move. The first drive component is a shaft driver, which can be understood as a hydraulic buffer. During the process of storing and releasing liquid in the hydraulic buffer, it is equivalent to the energy absorption and release process of the first damper. The hydraulic buffer can avoid excessively fast movement by controlling the flow rate of the internal liquid, thereby playing the role of damping shock and vibration. For example, when the load is too large, the hydraulic buffer can slowly release pressure to avoid sudden acceleration or deceleration, thereby ensuring the stability of the human-machine interface device connected to the hydraulic buffer. The hydraulic buffer includes a hydraulic cylinder, piston, piston rod, hydraulic cylinder head, buffer spring, sealing element and other structures. The working principle of the hydraulic buffer: the hydraulic cylinder is connected to the gun body. During the firing process, the gun body drives the hydraulic cylinder to recoil together. The piston rod of the buffer is connected to the shoulder support and rests against the shooter's shoulder. The cavity formed by the piston rod and the hydraulic cylinder is filled with hydraulic oil. After firing, the rifle recoils under the combined force of the barrel. The shoulder stock can be considered fixed, and the hydraulic cylinder moves rearward relative to the piston rod. The volume of the cavity formed by the hydraulic cylinder and piston, away from the hydraulic cylinder head, decreases, and the fluid pressure increases. This forces hydraulic oil to flow into the cavity between the hydraulic cylinder and the cylinder head and piston through the annular drain. Simultaneously, the buffer spring is compressed, storing recoil energy. Because the area of ​​the annular drain is much smaller than the piston area, the fluid flows at a high velocity through the annular drain, generating significant resistance, thus buffering the recoil of the rifle. When the recoil energy is dissipated, the rifle recoils to its final position. At this point, the buffer spring relaxes, pushing the rifle back to its pre-firing position. The piston rod moves rearward relative to the hydraulic cylinder, and the hydraulic oil flows back through the annular drain to the cavity formed by the hydraulic cylinder and piston, away from the hydraulic cylinder head.

[0036] And / or, the vibration damping component 1 includes a vibration damping pad disposed on the human-machine interface device. The vibration damping pad may be made of a material with a certain elasticity, such as rubber or polyurethane, which can absorb vibration energy. And / or, the vibration damping component 1 includes a first support base and a first elastic element. The two ends of the first elastic element are respectively connected to the first support base and the human-machine interface device. In this case, multiple vibration damping components 1 may be arranged along the circumference of the human-machine interface device. When the human-machine interface device is subjected to external vibration, the deformation of the first elastic element plays a buffering and vibration damping role. The first elastic element may be an elastic structure such as a spring that can play a vibration damping role.

[0037] In addition to the above, the vibration damping component 1 can also be a locking rod and a locking hole. Specifically, the sway protection device includes a second support base, on which a human-machine interface device is provided. The second support base is provided with several locking rods, and the human-machine interface device is provided with several locking holes that cooperate with the locking rods. The locking rods and locking holes constitute the vibration damping component 1. At this time, there may be no direct connection between the human-machine interface device and the second support base. When the human-machine interface device needs to be placed on the second support base for viewing or other uses, the multiple locking rods are aligned with the locking holes, and the locking rods are inserted into the locking holes to fix and support the human-machine interface device, thereby improving the stability of the human-machine interface device. When the human-machine interface device is moved, the locking rods can be pulled out from the locking holes, thereby facilitating the smooth movement of the human-machine interface device.

[0038] Alternatively, the vibration damping component 1 includes an electromagnet and a ferromagnetic part. The electromagnet is mounted on the third support base, and the ferromagnetic part is provided on the human-machine interface device. The human-machine interface device is located on the third support base, and the coverage area of ​​the electromagnet is large enough so that the ferromagnetic part can still be attracted by the electromagnet after the human-machine interface device moves a certain distance relative to the third support base. When the electromagnet is energized, the electromagnet and the ferromagnetic part can be attracted together, that is, the human-machine interface device is fixed on the third support base by magnetic force. When the human-machine interface device needs to be moved, the electromagnet is de-energized, and the operator can directly pick up the human-machine interface device and move it, thereby alleviating the problem of high resistance during movement of the human-machine interface device due to its high stability under the action of the vibration damping component 1.

[0039] The vibration damping component 1 includes a fourth support base, on which a human-machine interface device is mounted. A fifth support base is located on the side of the fourth support base away from the human-machine interface device. Two connecting rods are located on the side of the fourth support base facing the fifth support base. The first end of the connecting rod is rotatably connected to the fourth support base, and the second end of the connecting rod is slidably connected to the fifth support base. A slider is located at the second end of the connecting rod, and a slide rail is located on the fifth support base to cooperate with the slider. A second elastic element is located between the second ends of the two connecting rods, and the two ends of the second elastic element are respectively connected to the second ends of the two connecting rods. The human-machine interface device can be fixed on the fourth support base or rotatably connected to the fifth support base. When the human-machine interface device is subjected to external vibration, the vibration is transmitted to the connecting rods through the third support base and pushes the connecting rods to slide on the slide rail, converting the vibration into the motion of the connecting rods, thus achieving initial cancellation of the vibration. If the vibration is strong, the two connecting rods continue to move in opposite directions and pull the second elastic element, achieving secondary cancellation of the vibration through the deformation of the second elastic element. The second elastic element can be a spring or other elastic structure that can achieve a vibration damping effect.

[0040] The sway protection device also includes: a second drive assembly, which is connected to the human-machine interface device via a transmission connection; the assist assembly 2 includes a reducer, through which the second drive assembly is connected to the human-machine interface device via the reducer, which increases the output force of the second drive assembly, enabling it to have sufficient force to drive the human-machine interface device to move; and / or, the assist assembly 2 includes several drive devices, all of which are connected to the human-machine interface device, allowing the human-machine interface device to move or rotate in one direction simultaneously via multiple drive devices. The second drive assembly and drive devices can specifically be drive structures 3 such as cylinders, electric push rods, and rotary motors.

[0041] The sway protection device includes an adjustable damping second damper connected to the human-machine interface device (HMI). When the HMI experiences vibration, the second damper generates a first damping force, thus forming a vibration damping component 1. When the HMI moves, the second damper generates a second damping force, thus forming an assist component 2. The second damper can be directly connected to the HMI or to a drive structure 3 that can move the HMI. When the HMI is used in situations where it may experience external vibrations, such as during travel, the damping force of the second damper is increased. Through the energy absorption and release process of the second damper, it effectively reduces shock and vibration. When the HMI needs to move, the damping force of the second damper is decreased to allow for smoother movement.

[0042] Furthermore, the sway protection device in this utility model also includes a controller. The vibration damping component and the assist component are both connected to the controller via signal. The controller can control the start and stop of the vibration damping component and the assist component.

[0043] The human-computer interaction device incorporates a piezoelectric film, which is connected to a container capable of storing electrical energy, such as a capacitor, battery, or inductor, via a conductive component. By using the piezoelectric film, vibrations generated externally or internally can be converted into electrical energy. Specifically, vibration causes the piezoelectric film to generate an electric charge, which is collected and stored in an energy storage container by a rectifier circuit connected to the piezoelectric layer. This energy storage container can then be connected to the drive structure 3 of the human-computer interaction device or other small electronic devices to supply power, thereby saving energy and reducing operating energy consumption. The piezoelectric layer can be made of materials that produce a piezoelectric effect, such as piezoelectric ceramics, and the conductive component can be a conductive structure such as a wire.

[0044] It should be noted that when the human-computer interaction device is connected to the drive structure 3 that can drive the human-computer interaction device to move, and the drive structure 3 is not a hydraulic drive component, the setting of the vibration damping component 1 and the assist component 2 should not hinder the movement of the human-computer interaction device.

[0045] In this utility model, "and / or" means that in the same sentence, the text content before and after "and / or" can exist simultaneously or separately. For example, "A and / or B" includes three cases: only A or B exists, and A and B exist simultaneously.

[0046] This utility model discloses multiple technical solutions, but does not provide any contrary technical teachings.

[0047] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
