[0039] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific implementation methods. The same figure marks in the accompanying drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Compared to the embodiments shown in the drawings, feasible embodiments within the scope of protection of the present invention may have fewer components, additional components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0041] Example 1

[0042] Embodiment 1 of the present invention discloses a car securing device for a car carrier, which is intended to automatically secure a car after it enters a corresponding loading platform 10 and parks in a predetermined parking space. For ease of description, the car securing device for a car carrier disclosed in this embodiment of the present invention will be referred to as the "securing device" below.

[0043] Figure 1 This is a schematic structural diagram of an exemplary fixing device disclosed in Example 1 of the present invention. Figure 1 In the illustrated embodiment, the fixture may include a loading platform 10 .

[0044] The loading platform 10 is used as a carrier for the car and is generally arranged behind the front of the car carrier. In general, the loading platform 10 is provided with a plurality of parking spaces arranged in sequence along a first horizontal direction, and each parking space extends along the first horizontal direction and is suitable for parking a car. For example, the present invention Figure 1 The embodiment shows a case where four parking spaces are arranged in sequence along a first horizontal direction on the loading platform 10. Of course, in other embodiments of the present invention, the number of parking spaces may be more or less, which is not limited here.

[0045] The horizontal first direction described in the present invention can be understood as the length direction of the loading platform 10, especially the car carrier, that is, the direction from the front to the rear of the car carrier. This design facilitates the parking of cars in the designated parking spaces as needed. Correspondingly, the horizontal second direction described below in the present invention is perpendicular to the horizontal first direction, that is, the horizontal second direction can be understood as the width direction of the loading platform 10, the width direction of the car carrier, or the width direction of the car to be fixed.

[0046] To secure a car parked in a single parking space, continue with Figure 1 , each parking space is provided with a fixing unit 20. Specifically, Figure 4 As shown, the fixing unit 20 may include fixing assemblies 21 corresponding one-to-one with the wheels of the vehicle. For example, the embodiment of the present invention illustrates a case where the fixing unit 20 includes four fixing assemblies 21, one for each of the four wheels of a typical sedan, namely, the two front wheels and the two rear wheels. In this case, the four fixing assemblies 21 may be divided into two groups, with the two fixing assemblies 21 in each group aligned in the second horizontal direction.

[0047] The single fixing assembly 21 is suitable for fixing a single wheel of a car. Figure 5 As shown, a single fixed assembly 21 may include a first driver 211, a second driver 212, and a fixing member 213. The first driver 211 is adapted to output reciprocating motion along a height direction, and the second driver 212 is disposed at the output end of the first driver 211 and adapted to output reciprocating motion along a second horizontal direction. Both the first driver 211 and the second driver 212 may be common linear actuators such as pneumatic cylinders and electric push rods.

[0048] The fixing member 213 is provided at the output end of the second driver 212 so that the fixing member 213 can reciprocate in both the height direction and the horizontal second direction.

[0049] In addition, a limiting member 22 is provided between the two fixing components 21 aligned in the second horizontal direction. Figure 4 In the case of four fixing assemblies 21 shown in the figure, a limiting member 22 is provided between two fixing assemblies 21 corresponding to the front wheels of the automobile and between two fixing assemblies 21 corresponding to the rear wheels of the automobile, that is, there are two limiting members 22 in total.

[0050] The limiting member 22 extends along the second horizontal direction and is configured to be movable up and down along the height direction. The lifting and lowering movement of the limiting member 22 can be achieved in a manner to be described below.

[0051] In order to more clearly and intuitively understand the working principle of the fixing unit 20 disclosed in this embodiment 1, the working process of the fixing unit 20 will be described below by taking the process of fixing a car in a single parking space as an example.

[0052] Specifically, after a vehicle enters the corresponding loading platform 10 and parks in the designated parking space, the vehicle is positioned within the space enclosed by the various fixing assemblies 21 of the fixing unit 20. Specifically, a single fixing assembly 21 is positioned outside the corresponding wheel. Simultaneously, two stoppers 22 are positioned between the vehicle's front and rear wheels. Furthermore, the fixing member 213 in each fixing assembly 21 is positioned coaxially with the corresponding wheel.

[0053] In the stage of fixing the car, refer to Figure 2 As shown, the limiting members 22 of the fixing unit 20 are raised to contact the outer sides of the corresponding wheels. Specifically, one limiting member 22 is raised to abut against the outer walls of the two front wheels of the vehicle, and the other limiting member 22 is raised to abut against the outer walls of the two rear wheels of the vehicle. The two limiting members 22 support and limit the wheels of the vehicle from the front and rear sides of the vehicle. The limiting members 22 of the fixing unit 20 cooperate to restrict the vehicle's degree of freedom in the first horizontal direction. Simultaneously, for each fixing assembly 21, the first driver 211 first drives the fixing member 213 to rise in the height direction so that it is higher than the corresponding wheel. Then, the second driver 212 drives the fixing member 213 to move in the second horizontal direction toward the wheel until the fixing member 213 extends into the gap between the corresponding wheel and the vehicle body. Then, the first driver 211 drives the fixing member 213 to descend in the height direction so that the fixing member 213 applies downward pressure to the corresponding wheel. The fixing members 213 cooperate to restrict the vehicle's degree of freedom in the height direction and the second horizontal direction.

[0054] It can be seen that the fixing device disclosed in the embodiment of the present invention can replace manual labor to reliably fix the car by arranging the above-mentioned fixing units 20 at each parking space. Compared with the traditional method of manually fixing the car, it helps to reduce manual labor intensity and reduce the operational risks brought about by manual fixing of the car, and can ensure that the car is reliably fixed, thereby ensuring the safety of the car carrier during transportation.

[0055] In some embodiments, as Figure 5 As shown, each fixed assembly 21 may further include a movable base 214 capable of reciprocating along a first horizontal direction. The movable base 214 may reciprocate along the first horizontal direction under the drive of a known linear drive mechanism suitable for outputting reciprocating linear motion, for example, the linear drive mechanism may be a linear slide.

[0056] The first driver 211 may be disposed on the movable seat 214 so that the position of the entire fixing assembly 21 in the horizontal first direction is adjustable.

[0057] It is worth noting that by setting the position of the fixing component 21 in the horizontal first direction to be adjustable, the fixing part 213 in the fixing component 21 can be smoothly coaxial with the corresponding wheel by adjusting the position of the fixing component 21, and the entire fixing unit 20 is suitable for fixing cars with a variety of different wheelbases, which effectively improves the applicability of the fixing unit 20.

[0058] In some embodiments, when the position of the fixing assembly 21 is adjusted, the limiting member 22 can move synchronously with the corresponding fixing assembly 21 and the limiting member 22 can be raised and lowered in the height direction.

[0059] Reference Figure 4 and Figure 6 As shown, the limiting member 22 can be in a U-shaped structure. The two ends of the limiting member 22 can be rotatably connected to the corresponding two fixing components 21, especially the movable base 214 of the fixing component 21, so that the limiting member 22 can be raised and lowered in the height direction by rotating.

[0060] Specifically, the fixing unit 20 also includes a rotating drive component (not shown in the figure) that corresponds one-to-one to the limit member 22. The rotating drive component can be set on any one of the two fixed components 21 corresponding to the limit member 22, and the rotating drive component is used to drive the limit member 22 to rotate, so that the limit member 22 can adjust its position in the height direction by rotation, thereby realizing the lifting and lowering of the limit member 22 along the height direction.

[0061] It is understandable that by allowing the limiting member 22 to rotate itself to achieve the lifting of the limiting member 22, it helps to simplify the structure and improve space utilization. In addition, the angle between the limiting member 22 and the horizontal plane can be changed by rotation, so that it can support and limit the wheels of cars of different types and specifications at a better angle. The rotating drive component can be a motor. Figure 6 That is, it shows the situation after each limiting member 22 rotates a certain angle to rise to a certain height.

[0062] In some embodiments, reference Figure 3 As shown, the loading platform 10 can also be provided with a clearance groove 30 that corresponds to and fits with the limiting member 22. When the limiting member 22 rotates to be parallel to the horizontal plane, the limiting member 22 is accommodated in the clearance groove 30. Figure 1 Such a design is helpful in preventing the limiting member 22 from interfering with the vehicle traveling on the loading platform 10 .

[0063] In some embodiments, as Figure 4 or Figure 6As shown, the fixing unit 20 may further include a lifting support member 23, which is arranged below each of the limit members 22 of the fixing unit 20 and can be raised and lowered in the height direction. The lifting support member 23 can be raised and lowered by a lifting drive component (not shown) such as a hydraulic cylinder.

[0064] Reference Figure 2 As shown, by setting the lifting support member 23, when each limiting member 22 of the fixing unit 20 is raised by rotation to counteract the wheel of the car, and the position of the limiting member 22 no longer changes, the lifting support member 23 can be raised to support each limiting member 22 at the same time, thereby ensuring that each limiting member 22 can provide reliable support and limitation for the car.

[0065] In some embodiments, the lifting support member 23 extends along the horizontal first direction so that after the position of each limit member 22 changes with the fixing assembly 21, the lifting support member 23 can still reliably support the limit members 22 of the fixing unit 20.

[0066] In some embodiments, continue to refer to Figure 3 Limiting platforms 40 may also be provided on opposite sides of the loading platform 10 in the second horizontal direction. Limiting surfaces 41 extending along the first horizontal direction and tilted upward are provided on the facing sides of the two limiting platforms 40. This arrangement facilitates further limiting the freedom of movement of a vehicle parked on the loading platform 10 in the second horizontal direction by means of the limiting surfaces 41 of the limiting platforms 40, thereby further reducing the possibility of the vehicle moving off the side of the loading platform 10.

[0067] Example 2

[0068] On the basis of Example 1, in order to further improve the degree of automation when fixing the car on the loading platform 10, Example 2 of the present invention discloses another fixing device for a car carrier. Different from Example 1, the fixing device disclosed in Example 2 can also include a position detection component (not shown in the figure) and a controller (not shown in the figure) corresponding to the parking space one by one.

[0069] The position detection assembly and the fixed unit 20 are both communicatively connected to the controller. Specifically, the communication connection between the fixed unit 20 and the controller refers to the communication connection between the first and second drivers 211 and 212 of the fixed assembly 21, the linear drive mechanism for driving the movable seat 214, the rotation drive component for driving the limiter 22, and the lifting drive component for driving the lifting support 23.

[0070] The position detection component is configured to obtain wheel position information of a car parked at a corresponding parking space and send the wheel position information to the controller.

[0071] The controller is configured to determine the position of each wheel of the vehicle based on the wheel position information sent by the position detection component; and the controller is further configured to control the fixing unit 20 to fix the vehicle based on the position of each wheel of the vehicle.

[0072] Specifically, after the controller determines the position of each wheel of the vehicle based on the wheel position information transmitted by the position detection component, the controller controls each fixing component 21 in the fixing unit 20 to move until the fixing member 213 is coaxial with the corresponding wheel. On this basis, under the control of the controller, the rotation drive component drives the limiting member 22 to rotate until each limiting member 22 of the fixing unit 20 rises to abut against the outer wall of the corresponding wheel, thereby limiting the vehicle's degree of freedom in the first horizontal direction. After the position of the limiting member 22 is determined, the controller controls the lifting drive component to drive the lifting support member 23 to rise to support the limiting member 22. At the same time, under the control of the controller, the fixing member 213 of each fixing component 21 extends into the gap between the corresponding wheel and the vehicle body in the manner described in Example 1, and applies downward pressure to the wheel from above the corresponding wheel, thereby reliably fixing the entire vehicle.

[0073] Among them, the position detection component can be a pressure sensor array arranged along the horizontal first direction on the corresponding parking space (not shown in the figure). When the car enters the parking space, the position of each wheel of the car can be determined by the pressure sensors in the pressure sensor array that are under pressure.

[0074] It can be seen that through the setting of the position detection component and the controller, after the car is parked in the predetermined parking space, the fixing unit 20 can be used in conjunction with the controller to automatically fix the car, effectively overcoming the disadvantages of traditional manual fixing of the car.

[0075] In some embodiments, a first pressure sensor (not shown) in communication with the controller may also be provided on the stopper 22. The first pressure sensor is configured to obtain first pressure information between the stopper 22 and the wheel of the vehicle and send the first pressure information to the controller.

[0076] The controller is also configured to dynamically adjust the pressure between the limit member 22 and the wheel of the car based on the first pressure information sent by the first pressure sensor. Specifically, the controller adjusts the pressure between the limit member 22 and the wheel of the car by adjusting the rotation angle of the limit member 22 so that the pressure between the limit member 22 and the wheel meets the preset pressure threshold, thereby ensuring that the limit member 22 reliably supports and limits the wheel.

[0077] In some embodiments, the fixing device may further include a Hall effect sensor (not shown) in communication with the controller. The Hall effect sensor corresponds one-to-one with each stopper 22. The Hall effect sensor is configured to obtain rotation angle information of the corresponding stopper 22 and transmit the rotation angle information to the controller. The controller can then determine the rotation angle of the corresponding stopper 22 based on the rotation angle information transmitted by the Hall effect sensor, thereby enabling the controller to rotate the corresponding stopper 22 to a predetermined angle according to preset requirements.

[0078] In some embodiments, a second pressure sensor (not shown) in communication with the controller may be further provided on the lifting support 23. The second pressure sensor is configured to obtain second pressure information between the lifting support 23 and the limiting member 22 and transmit the second pressure information to the controller.

[0079] The controller is also configured to dynamically adjust the rising height of the lifting support member 23 based on the second pressure information sent by the second pressure sensor, so as to dynamically adjust the pressure between the lifting support member 23 and the limit member 22 to ensure that the lifting support member 23 can provide reliable support for the limit member 22.

[0080] In some embodiments, a vibration sensor (not shown) in communication with the controller may also be provided on the stopper 22. It is understood that, by providing the vibration sensor, the vibration of the corresponding vehicle can be detected by the vibration sensor during normal operation of the car carrier to transport the vehicle. This allows the controller to comprehensively determine, based on the vehicle vibration and the rotation angle of the stopper 22, whether the stopper 22 will change its rotation angle due to the vibration amplitude, resulting in the stopper 22 being unable to effectively limit the vehicle's wheels, thereby dynamically monitoring the state of the stopper 22.

[0081] Furthermore, if it is determined that the stopper 22 can no longer effectively restrain the wheel (i.e., the vehicle may become loose), the controller can promptly issue a warning message, for example, in the cab of the car carrier, to alert relevant personnel such as the driver. Simultaneously, the controller can dynamically adjust the rotation angle of the stopper 22 and / or the elevation of the lifting support 23 based on the judgment result, thereby allowing the controller to dynamically adjust the pressure between the stopper 22 and the wheel according to the vibration of the vehicle, thereby achieving dynamic monitoring and improving the reliability of the stopper 22 in restraining the vehicle.

[0082] In some embodiments, each fixed component 21, particularly the first driver 211, may further be provided with a camera (not shown) in communication with the controller. The camera is directed toward the wheel corresponding to the fixed component 21 and is configured to capture image information of the wheel corresponding to the fixed component 21 and transmit the image information to the controller.

[0083] The controller is further configured to determine the outline of the wheel corresponding to the fixing assembly 21 based on the image information transmitted by the camera, and thereby determine the wheel diameter based on the wheel outline, so that the fixing assembly 21 can more accurately move its fixing member 213 to be coaxial with the corresponding wheel. This method is suitable for automated fixing of vehicles with multiple wheel diameters.

[0084] In some embodiments, an infrared sensor (not shown) and an ultrasonic sensor (not shown) may be further provided on each fixing assembly 21, particularly the second actuator 212. The infrared sensor and the ultrasonic sensor are configured to respectively obtain first distance information and second distance information between the fixing assembly 21 and the corresponding wheel in a second horizontal direction, and transmit the first distance information and the second distance information to the controller.

[0085] The controller is further configured to determine a first distance and a second distance between the fixing assembly 21 and the corresponding wheel in a second horizontal direction based on the first distance information transmitted by the infrared sensor and the second distance information transmitted by the ultrasonic sensor, so that the controller can comprehensively determine whether the distance between the fixing assembly 21 and the corresponding wheel in the second horizontal direction meets a preset distance threshold based on the first distance and the second distance. If both the first distance and the second distance meet the preset distance threshold, the controller automatically controls the fixing member 213 of the fixing assembly 21 to apply downward pressure to the wheel from above the corresponding wheel.

[0086] It can be understood that by setting an infrared sensor and an ultrasonic sensor to simultaneously detect the distance between the fixing component 21 and the corresponding wheel in the second horizontal direction, compared with setting only one ranging sensor, it is beneficial to improve the accuracy of detecting the distance between the fixing component 21 and the corresponding wheel in the second horizontal direction.

[0087] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
