Description

Technical Field

[0001] The present invention relates to the technical field of automobile shock absorption, and in particular to an intelligent automobile anti-shock system and method. Background Art

[0002] As new energy vehicles are widely loved by the public, the demand for integrated condensing unit modules is gradually increasing. With the requirements of existing commercial vehicles to carry heavy objects, the vibration performance requirements of each module on the vehicle are also getting higher and higher. It is usually necessary to set a shock-absorbing structure on the vehicle to meet the intelligent anti-seismic function of multiple road conditions.

[0003] The most common shock-absorbing structure currently is to fill the module with flexible parts between the frame of the passenger car to provide buffering and reduce collision. However, its structure is too simple and can only control limited relatively micro-vibration. When the vehicle turns sharply or travels in a rough process, vibration and noise cannot be avoided, and it is impossible to quickly stabilize. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent anti-vibration system and method for a vehicle, which can solve the technical problems of vibration, noise and rapid stabilization that cannot be avoided when the vehicle makes a sharp turn or has a rough journey.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] The present invention designs an intelligent anti-seismic system for a vehicle, including a controller module, a sensor module, and an anti-seismic module.

[0007] The controller module is used to calibrate and control the vehicle sensor;

[0008] The sensor module is used to monitor the vibration frequency of the vehicle, obtain the real-time vibration data of the vehicle, and transmit it to the anti-vibration module through the controller module;

[0009] The anti-seismic module is arranged between the load-bearing device and the vehicle. According to different working conditions of the vehicle, the controller module controls the anti-seismic module to perform sub-item or combined movements to change the amplitude of the load-bearing device located above the anti-seismic module and reduce the impact of vehicle vibration on the load-bearing device.

[0010] As a preferred solution, the movement of the anti-seismic module includes vertical up and down movement of the screw rod and / or horizontal rotation movement of the robot arm.

[0011] Furthermore, the vertical up and down movement of the screw rod is realized by a moving component consisting of a movable screw rod and a servo motor thereunder. The servo motor drives the movable screw rod to rotate and move upward or downward through an electrical signal, thereby supporting the upper cover of the anti-seismic module, so that the supporting equipment and the entire vehicle can move up and down relative to each other.

[0012] Furthermore, the horizontal rotation movement of the robotic arm is realized by combining two robotic arms and a turntable in the middle to form a rotating component. The two robotic arms drive the turntable in the middle to rotate at a certain speed, and the turntable drives the upper cover of the anti-seismic module to rotate, thereby driving relative rotation between the carrying equipment and the entire vehicle.

[0013] Furthermore, a coil and an electromagnet are arranged under the turntable, and a baffle is provided on the upper side of the movable screw rod. After power is turned on, the electromagnet is adsorbed to the baffle plate by the magnetic force of the coil, and the positioning pin on the baffle plate and the groove of the electromagnet are matched, thereby locking the movable screw rod so that it no longer moves, so that the anti-seismic module realizes the self-locking function.

[0014] The present invention also designs an intelligent anti-seismic method for a vehicle, comprising the following steps:

[0015] When the vehicle is started, the controller initializes and calibrates the vehicle sensors;

[0016] The real-time data of the vehicle is obtained through the vehicle sensor, transmitted to the processing unit of the controller, and fed back to the anti-vibration module. The anti-vibration module compensates the output up and down movement rate or rotation angular velocity according to the feedback value to form a closed-loop control design;

[0017] The controller's processing unit calculates the optimal shock absorber movement pattern and rate required and adjusts the shock absorbers at each mounting point;

[0018] According to different working conditions of the vehicle, the step angle of the servo motor in the shock absorber is adjusted to change the up and down stroke of the movable screw rod, and / or the input torque of the joint motor is adjusted to change the angle of the mechanical arm joint, thereby changing the movement of various parts of the shock absorber, so that the load-bearing equipment above the shock absorber can remain relatively stable in various environments, reducing the impact of road conditions and vibration transmitted by the vehicle;

[0019] The anti-seismic module performs self-learning based on vehicle driving data and optimizes control parameters.

[0020] As a preferred solution, when the load-bearing equipment is in a natural state and the vehicle is moving relatively smoothly, the parameters of the seismic module are set as follows:

[0021] The default state of the anti-seismic module is defined as the up and down movement rate Vb = 0, the rotation angular velocity a1 = a2 = 0; the movable screw is in the adjustable displacement middle state, that is, ΔL / 2; the initial position angle of the two side robotic arms is α1 = α2, and the middle angle is β1 = β2;

[0022] Vb-the rate at which the anti-seismic module moves up and down;

[0023] ΔL-total displacement of the seismic module moving up and down;

[0024] a1, a2-rotational angular velocity of the two manipulators of the anti-seismic module;

[0025] α1, α2 - the angles between the two mechanical arms of the anti-seismic module close to the housing end;

[0026] β1, β2 - the angle between the two middle arms of the anti-seismic module.

[0027] As a preferred solution, when the road is bumpy or the slope gradient is large, or the vehicle moves too fast, the vehicle shakes greatly in the Z direction. The parameters of the anti-seismic module are set as follows:

[0028] The default state of the anti-seismic module is defined as the up and down movement rate Vb = Kc, the rotation angular velocity a1 = a2 = 0, the movable screw supports the upper cover and moves up and down, and the displacement is ΔL; the initial position angles of the two side robotic arms are α1 = α2, and the middle angle is β1 = β2;

[0029] Kc-constant value.

[0030] As a preferred solution, in the case of curved mountain roads or sharp turns, and when the vehicle turns too fast, the vehicle may be in danger of tilting due to excessive centripetal force at the turn. The parameters of the anti-seismic module are set as follows:

[0031] The default state of the anti-seismic module is defined as the up and down movement rate Vb = 0, the rotation angular velocity a1 = a2 = k3, and the movable screw is in the adjustable displacement middle state, that is, ΔL / 2; the initial position angles of the two side robotic arms α1 = α2 are in the active state, and the middle angle β1 = β2 is in the active state;

[0032] K3 - constant value.

[0033] As a preferred solution, when the mountain road has dense turns or turns at an extremely fast rate, and the vehicle turns too fast, the vehicle may be affected by the centripetal force too much at the turn and may be in danger of tilting. The parameters of the anti-seismic module are set as follows:

[0034] The default state of the anti-seismic module is defined as the up and down movement rate Vb=Kc, the rotation angular velocity a1=a2=k3, the movable screw supports the upper cover and moves up and down, and the displacement is ΔL; the initial position angles α1=α2 of the two side robotic arms are in the active state, and the middle angle β1=β2 is in the active state.

[0035] Beneficial effects of the present invention:

[0036] The present invention provides an intelligent anti-vibration system and method for a vehicle, which can solve the technical problems of unavoidable vibration, noise and rapid stabilization when the vehicle makes a sharp turn or has a rough journey.

[0037] The upper and lower screw rods and the rotating mechanical arm in the present invention have the ability of high-precision control rate and reliable buffer interlocking. According to the different working conditions of the whole vehicle, the up and down movement of the screw rod in the anti-seismic module and the horizontal rotation movement of the turntable can be divided into items or combined movements, which is convenient for rapid response, effectively improving the stability and service life of the operating environment of the carrying equipment and reducing noise.

[0038] The intelligent anti-seismic module of the present invention can change the movement amplitude of the load-bearing device by monitoring the driving state of the vehicle in real time and quickly adjusting the movement state of the shock absorber.

[0039] The rubber shock-absorbing pad of the present invention has the advantages of absorbing and dispersing impact energy of the traditional shock-absorbing pad and reducing the vibration and noise generated during the use of the bearing equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention are further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, not all.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] The present invention provides an intelligent anti-seismic system and method for a vehicle, which can adaptively adjust the height according to different road conditions when the vibration is small; in the case of slightly larger vibration, the height and rotation of the anti-seismic module can be further controlled by monitoring the vibration frequency value, thereby reducing vibration, avoiding resonance, being more friendly to the contact surface, and improving stability. The anti-seismic module of the present invention is mainly used for commercial vehicles, etc., and the anti-seismic module carries important bearing equipment such as thermal management cooling modules and motor electronic control units. A single bearing device is arranged with several anti-seismic modules according to the installation position, and they are all placed horizontally. The whole vehicle vibrates greatly when encountering extreme road conditions when carrying heavy objects, and is transmitted to the important bearing equipment placed above, which will greatly reduce the durability of the components and cause excessive noise. Using the intelligent anti-seismic module proposed in the present invention, the upper bearing equipment can be effectively and accurately stabilized, the vibration impact of the whole vehicle can be reduced, the service life and reliability of the product can be improved, and the noise can be reduced at the same time.

[0054] The present invention proposes an intelligent anti-seismic system capable of adjusting the amplitude of a load-bearing device, comprising a controller module, a sensor module and an anti-seismic module. The controller module is used to calibrate and control the vehicle sensor; the sensor module is used to monitor the vibration frequency of the vehicle, obtain the real-time vibration data of the vehicle, and transmit it to the anti-seismic module through the controller module; the anti-seismic module is arranged between the load-bearing device and the vehicle, and according to different working conditions of the vehicle, the controller module controls the anti-seismic module to perform sub-item or combined movements, so as to change the amplitude of the load-bearing device located above the anti-seismic module, and reduce the influence of the vehicle vibration on the load-bearing device.

[0055] The movement mode of the anti-seismic module includes the vertical up and down movement of the screw rod and / or the horizontal rotation movement of the mechanical arm. The vertical up and down movement of the screw rod is realized by a moving part composed of a movable screw rod and a servo motor below it. The servo motor drives the movable screw rod to rotate and move upward or downward through an electrical signal, thereby supporting the upper cover of the anti-seismic module, so that the carrying device and the whole vehicle move up and down relative to each other. The horizontal rotation movement of the mechanical arm is realized by combining two mechanical arms and a turntable in the middle to form a rotating part. The two mechanical arms drive the turntable in the middle to rotate at a certain speed. The turntable drives the upper cover of the anti-seismic module to rotate, thereby driving the relative rotation between the carrying device and the whole vehicle. A coil and an electromagnet are arranged below the turntable, and a baffle is arranged on the upper side of the movable screw rod. After power is turned on, the electromagnet is adsorbed to the baffle by the magnetic force of the coil, and the positioning pin on the baffle is matched with the groove of the electromagnet, thereby locking the movable screw rod and stopping it from moving, so that the anti-seismic module realizes a self-locking function.

[0056] The main structure of the anti-seismic module: the controller is connected to the internal moving parts; the shock-absorbing pad and the upper cover are combined; the two mechanical arms are combined with the middle turntable to form a rotating part fixed to the outer shell of the anti-seismic module, the mechanical arm drives the middle turntable to rotate at a certain speed and angle, and the upper cover of the anti-seismic module drives the relative movement angle between the carrying equipment and the whole vehicle; the moving part composed of the movable lead screw and the servo motor below is fixed to the outer shell of the anti-seismic module, and the servo motor drives the lead screw to rotate upward or downward through electrical signals, thereby supporting the upper cover of the anti-seismic module to enable the carrying equipment and the whole vehicle to move up and down relative to each other.

[0057] Advantages of the intelligent anti-vibration system for vehicles:

[0058] With efficient response time, the controller can complete data processing and shock absorber movement adjustment in milliseconds.

[0059] Scalability: The controller can be modularly upgraded according to the sensor types or functions added in the future.

[0060] Energy-saving design: the anti-vibration system starts the motor to adjust the movement of the anti-vibration module only when necessary to avoid excessive power consumption.

[0061] The present invention also proposes an intelligent anti-seismic method for a vehicle, comprising the following steps:

[0062] When the vehicle is started, the controller initializes and calibrates the vehicle sensors;

[0063] Real-time data is obtained through vehicle sensors (such as accelerometers, gyroscopes, vehicle speed sensors, brake sensors, etc.), transmitted to the processing unit of the controller, and fed back to the anti-vibration module. The anti-vibration module compensates the output up and down movement rate or rotation angular velocity according to the feedback value to form a closed-loop control design;

[0064] The processing unit of the controller calculates the optimal required movement pattern and rate of the shock absorber according to the preset algorithm, and adjusts the shock absorber at each mounting point through the execution unit;

[0065] According to different working conditions of the vehicle, the step angle of the servo motor in the shock absorber is adjusted to change the stroke of the lead screw at the front end of the motor or the input torque of the joint motor to change the angle of the robot arm joint to change the movement of various parts, so that the load-bearing equipment above the shock absorber can remain relatively stable in various environments, reducing the impact of road conditions and the vibration transmitted by the whole vehicle, and improving the durability and noise of the load-bearing equipment.

[0066] The anti-seismic module performs self-learning based on vehicle driving data and optimizes control parameters.

[0067] The intelligent anti-seismic module of the present invention can obtain real-time data through vehicle sensors (such as accelerometers, gyroscopes, vehicle speed sensors, brake sensors, etc.), transmit it to the processing unit, and feed it back to the ECU inside the anti-seismic module. The ECU can perform PID compensation on the output up and down movement rate or the angular velocity of rotation according to the feedback value to form a closed-loop control design. Relying on the closed-loop control, the upper and lower screw rods and the rotating mechanical arm in the present invention have the ability to control the rate with high precision. According to the different working conditions of the whole vehicle, the anti-seismic module can move in separate items or in combination, which is convenient for rapid response to changes in the amplitude during the movement of the load-bearing equipment, effectively improving the service life of the load-bearing equipment and reducing noise.

[0068] The present invention specifically analyzes the motion state of the anti-seismic module required under several working conditions, and the vibrations at different positions on the same vehicle may also be different. It is necessary to calculate the motion state and rate of each position based on actual detection data to meet the requirements.

[0069] 1) Define the default state of the anti-seismic module as the up and down movement rate Vb = 0 (the screw is in the adjustable displacement middle state, i.e. ΔL / 2), the rotation angular velocity a1 = a2 = 0 (the initial position angle of the two sides α1=α2, the middle angle β1=β2), at this time, several anti-seismic modules are installed at the installation point between the load-bearing equipment and the whole vehicle. At this time, the rubber shock-absorbing pad in the anti-seismic module has the characteristics of high elasticity and high viscosity, which enables it to effectively absorb and disperse the impact energy, thereby reducing the vibration and noise generated during the use of the load-bearing equipment.

[0070] This is suitable for the natural state of the load-bearing equipment and the relatively stable working conditions of the vehicle:

[0071] 1. V = 0, a = 0;

[0072] 2. V = Ka, a = 0 (the vehicle speed Ka ≤ ta);

[0073] 3. V≠0, a=Kb (the vehicle acceleration Kb≤tb);

[0074] 4. V≠0, a≠0 (the vehicle acceleration fluctuates in a small range);

[0075] Vb-the rate at which the anti-seismic module moves up and down;

[0076] ΔL-total displacement of the seismic module moving up and down;

[0077] a1, a2-rotational angular velocity of the two manipulators of the anti-seismic module;

[0078] α1, α2 - the angles between the two mechanical arms of the anti-seismic module close to the housing end;

[0079] β1, β2 - the angle between the two middle arms of the anti-seismic module;

[0080] V-the speed of the vehicle;

[0081] a-the vehicle's acceleration;

[0082] Ka, Kb - constant values; ta - speed limit of the whole vehicle, if it exceeds ta, the movement will be more violent; tb - acceleration limit of the whole vehicle, if it exceeds tb, the movement will be more violent.

[0083] 2) Define the default state of the seismic module as the up and down movement rate Vb = Kc (the screw rod pushes the upper cover up and down, and the displacement is ΔL), the rotation angular velocity a1 = a2 = 0 (the initial position angle of the two sides α 1= α 2, the middle angle β1 = β2), at this time, relative movement occurs between the load-bearing equipment and the whole vehicle in the Z direction, causing several anti-seismic modules to move, changing the amplitude of the upper load-bearing equipment, thereby reducing the vibration impact of the whole vehicle, so as to achieve the effect of extending the service life of the load-bearing equipment and improving the safety performance of the whole vehicle.

[0084] This is suitable for locations with bumpy roads or large slope gradients, and when the vehicle moves too fast, the vehicle will shake greatly in the Z direction.

[0085] 1. V = Ka, a = 0 (the vehicle speed Ka>ta at this time);

[0086] 2. V≠0, a=Kb (the vehicle acceleration Kb>tb at this time);

[0087] 3. V≠K1, a≠K2 (the road is bumpy or the slope gradient is large, and the vehicle's motion state is unstable);

[0088] Ka, Kb, Kc, K1~K3-constant values.

[0089] 3) Define the default state of the anti-seismic module as the up and down movement rate Vb = 0 (the screw is in the middle state of the adjustable displacement, i.e. ΔL / 2), the rotation angular velocity a1 = a2 = k3 (the initial position angles α1 = α2 on both sides are active, and the middle angle β1 = β2 is active). At this time, a relative rotation occurs along the Z direction between the load-bearing device and the whole vehicle. Taking the center of the circle generated by the whole vehicle during the rotation as the starting point, the central axes of the distributed anti-seismic modules are on different circles drawn with the starting point. Different relative movements occur through calculation, thereby changing the amplitude of the load-bearing device, improving the safety risks caused by the tilt of the whole vehicle, extending the service life of the load-bearing device, and improving the safety performance of the whole vehicle.

[0090] This applies to winding mountain roads or sharp turns, as well as when the vehicle is turning too fast. At this time, the vehicle is too greatly affected by the centripetal force at the turn and may be in danger of tilting.

[0091] 1. V = Ka, a = 0 (the vehicle speed Ka ≤ ta);

[0092] 2. V≠0, a=Kb (the vehicle acceleration Kb≤tb);

[0093] 3. V≠0, a≠0 (at this time, the acceleration of the whole vehicle fluctuates in a small range).

[0094] 4) Define the default state of the anti-seismic module as the up and down movement rate Vb=Kc (the screw rod pushes the upper cover up and down, and the displacement is ΔL), the rotation angular velocity a1=a2=k3 (the initial position angles α1=α2 on both sides are in an active state, and the middle angle β1=β2 is in an active state). At this time, relative movement and relative rotation occur between the load-bearing equipment and the whole vehicle along the Z direction, so that several anti-seismic modules change the amplitude of the load-bearing equipment at the calculated relative motion trajectory and rate, thereby reducing the impact of severe vibration of the whole vehicle, extending the service life of the load-bearing equipment, and improving the safety performance of the whole vehicle.

[0095] This applies to more extreme road conditions, such as mountain roads with dense turns or turns at an extremely fast rate, and the vehicle's steering speed is too fast. At this time, the vehicle is too affected by the centripetal force at the turn and may be in danger of tilting.

[0096] 1. V = Ka, a = 0 (the vehicle speed Ka>ta at this time);

[0097] 2. V≠0, a=Kb (the vehicle acceleration Kb>tb at this time);

[0098] 3. V≠K1, a≠K2 (the vehicle is in a very unstable state at this time).

[0099] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0100] As attached Figure 1 As shown: the intelligent anti-seismic module in the present invention includes: a controller 1; a shock-absorbing pad assembly 2; two mechanical arms combined with a middle turntable constitute a rotating component 3 fixed to the housing 4 of the anti-seismic module, the mechanical arms drive the middle turntable to rotate at a certain speed and angle, and the upper cover of the anti-seismic module drives the bearing device and the whole vehicle to have a relative movement angle; a moving component 5 composed of a movable lead screw and a servo motor below is fixed to the housing 4 of the anti-seismic module, and the servo motor drives the lead screw to rotate and move upward or downward through an electrical signal, thereby supporting the upper cover of the anti-seismic module so that the bearing device and the whole vehicle can move up and down relative to each other.

[0101] The controller 1 combines the intelligent and precise control mode of the whole vehicle, which means that the anti-seismic module ECU communicates with the CAN bus of the whole vehicle ECU, reads the parameters of each sensor on the whole vehicle in real time, automatically adjusts according to the real-time road conditions and driving conditions, monitors the driving status of the vehicle in real time and quickly adjusts the movement status of the shock absorber to change the movement amplitude of the load-bearing equipment.

[0102] Controller hardware structure:

[0103] a) The controller includes a sensor module, a processing unit, a storage unit and an execution unit.

[0104] b) The sensor module is used to obtain parameters such as vehicle speed, acceleration, steering angle, and road conditions in real time.

[0105] c) Based on the sensor data, the processing unit uses a control algorithm to analyze and calculate the optimal motion state and motion rate of the shock absorber to meet the change of the effective motion amplitude of the load-bearing equipment, thereby reducing the impact of the vehicle vibration on the load-bearing equipment.

[0106] d) The storage unit is used to store control algorithms and historical data to optimize the regulation strategy.

[0107] e) The execution unit is used to send adjustment instructions to the shock absorber and drive the servo motor actuator.

[0108] Software control algorithm:

[0109] a) Based on fuzzy control, PID control, machine learning and other technologies, the parameters of the shock absorber actuator adjustment are calculated in real time in combination with sensor data.

[0110] b) The system can adaptively learn, optimize adjustment strategies, and enhance shock absorption effects.

[0111] As attached Figure 2 The shock-absorbing pad assembly 2 is shown, the upper cover 2.1 and the metal frame 2.2 in the middle of the shock-absorbing pad are integrally welded, the metal frame 2.2 and the rubber shock-absorbing pad 2.3 are adhered together by a pad adhesive, and the turntable 2.4 below is also adhered together with the rubber shock-absorbing pad 2.3 by a pad adhesive, wherein the middle part of the two metal frames is used to absorb and disperse the impact energy, thereby reducing the vibration and noise generated during the use of the bearing equipment.

[0112] As attached Figure 3 The figure shows that two mechanical arms and the middle turntable are combined to form a rotating component 3 fixed to the housing 4 of the anti-seismic module. The mechanical arms are connected by a series of rigid components (connecting rods) 3.1 through joints. The joint motors of the mechanical arms input the required torque in different postures. The rotating joints provide freedom for the mechanical arms. The rotation angle of the end turntable is calculated according to the joint angle, and the angular velocity of the turntable 2.4 depends on the vibration environment of the whole vehicle (the rotation angle Δθ is constant). Among them, the spring 3.2 and the suspension ball 3.3 mainly play a buffering role.

[0113] As attached Figure 4 The moving part 5 composed of the movable lead screw and the servo motor below is fixed to the housing 4 of the anti-seismic module. The servo motor 5.1 changes the stroke of the lead screw 5.2 at the front end of the motor by adjusting the step angle. The lead screw spirally drives the turntable up and down to make the anti-seismic module move relative to each other in the Z direction. The movement displacement ΔL=nXt (t is the lead screw pitch). The upper end of the lead screw is a light rod, and a rolling bearing 5.3 is installed between the lead screw and the turntable 2.4. The lead screw and the turntable do not rotate relative to each other, and only relative movement occurs in the Z direction. A coil and an electromagnet 5.4 are installed between the lead screw 5.2 and the turntable 2.4. After power is turned on, the electromagnet 5.4 is magnetically attracted to the baffle 5.5 by the coil inside the turntable 2.4. The positioning pin on the baffle 5.5 is matched with the magnet groove, and the thread below the electromagnet 5.4 is consistent with the thread specification of the lead screw, thereby locking the lead screw and stopping it from moving, further ensuring the reliability of the movement of the anti-seismic module and avoiding failure due to long-term operation.

[0114] As attached Figure 5The figure shows the application schematic diagram of the present invention on the thermal management cooling module. Two anti-vibration modules 7 are arranged horizontally on the carrier device 8. The rubber shock-absorbing pads in the anti-vibration modules have the characteristics of high elasticity and high viscosity, so that they can effectively absorb and disperse the impact energy, thereby reducing the vibration and noise generated during the use of the carrier device.

[0115] When using the anti-seismic module of the present invention, in addition to the traditional rubber shock absorption and dispersion of impact energy, the movement mechanism: the up and down movement of the screw rod and the horizontal rotation movement of the turntable can be separated or combined to adapt to various scenarios, ensuring that the bearing equipment on the anti-seismic module reduces the movement amplitude and operates in a more stable environment, thereby achieving the purpose of shock absorption and noise reduction and increasing the service life of the bearing equipment.

[0116] The present invention is applicable to shock absorption of commercial vehicles / passenger vehicles, and the anti-seismic module is fixed to the vehicle frame with fasteners. In addition, the present invention is also applicable to the cooling system or other components of new energy vehicles, and the anti-seismic module can be used in any installation position.

[0117] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
