[0002] Flatbed trucks are of great significance in the field of transportation. They can be used as special trailers for transporting vehicles. New vehicles are usually transported on flatbed trucks to avoid mileage increase and reduce potential damage risks after leaving the factory, so as to ensure that customers can receive their vehicles in the best condition. When loading a passenger car, carefully drive the passenger car onto the flatbed truck, ensure that the wheels are completely placed on the parking plate of the flatbed truck, and then fix the wheels of the passenger car with fixing devices to complete the loading.

[0003] For example, a Chinese patent with application number 202010514759.7 discloses a multifunctional adjustable vehicle carrier transport vehicle, including a vehicle body, on which a fixing device is arranged, including a driving mechanism arranged on the lower parking plate and a clamping and fixing mechanism arranged on the driving mechanism, the clamping and fixing mechanism is specifically located on the side of the lower parking plate; the clamping and fixing mechanism includes a pillar, a circular disc arranged on the top of the pillar, and a flexible clamping claw arranged on the circular disc, the flexible clamping claw is provided with at least two groups, and the multiple groups of flexible clamping claws are all centered on the center of the circular disc, and the circular disc is aligned with the wheel of the vehicle; the driving mechanism drives the arc of the pillar to approach or away from the vehicle wheel until the multiple groups of flexible clamping claws are clamped on the vehicle wheel. In the above scheme, since the clamping and fixing mechanism is fixed on the lower parking plate, the clamping and fixing mechanism can only fix passenger cars with the same wheelbase, that is, the flatbed truck can only be used to transport passenger cars with one wheelbase, which makes the versatility of the flatbed truck low. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the existing technology and propose a fixing device for fixing a passenger car on a flatbed truck. The technical problem to be solved by the utility model is: how to improve the versatility and transportation safety.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] According to the wheelbase between the front and rear wheels of the passenger car, the base position is adjusted by moving the driving mechanism to drive the adjustment grille to slide in the guide groove. After adjustment, the passenger car is driven to a fixed position and the four wheels are fixed by the clamping assembly. The adjustment of the base position is achieved by cooperating with the adjustment grille and the guide groove to lock the passenger car with different wheelbases. The adjustment is more flexible and more versatile. At the same time, the coordination structure of multiple adjustment grilles and guide grooves is simple. Its design and function make the transportation process more economical and can share the force during the transportation of the flatbed truck, reduce the shaking during transportation, and improve the stability and safety of transportation.

[0008] In the above-mentioned fixing device for fixing a passenger car on a flatbed truck, a sliding groove is opened downward on the parking plate, and a plurality of guide grooves are symmetrically distributed on the front and rear sides of the sliding groove, and the base is slidably arranged in the sliding groove along the front and rear directions of the sliding groove. The setting of the sliding groove enables the base to sink, which can improve the stability during transportation and increase the use area of ​​the parking plate, so that the wheels of the passenger car can be loaded on the base. At the same time, the contact area between the bottom surface of the sliding groove and the base is large, which has a balanced support force on the base and increases stability.

[0009] In the above-mentioned fixing device for fixing a passenger car on a flatbed truck, the parking plate is flush with the top of the base. Since the parking plate is flush with the top of the base, a flat loading platform is formed when loading the wheels. This means that the wheels can slide smoothly to the loading position, reducing bumps and instability during loading. This flat loading platform helps to protect the wheels and reduce the risk of damage during loading.

[0010] In the above-mentioned fixing device for fixing a passenger car on a flatbed truck, the depth of the sliding groove is greater than the depth of the guide groove, and the bottom surface of the adjustment grille is in contact with the bottom surface of the guide groove. The groove depth of the sliding groove is greater than the groove depth of the guide groove, which can provide a more stable loading effect. The bottom surface of the adjustment grille is in contact with the bottom surface of the guide groove, so that the adjustment grille can also obtain support from the parking board, further improving the bearing capacity of the fixing device, thereby improving stability.

[0011] In the above-mentioned fixing device for fixing a passenger car on a flatbed truck, the top surface of the base is recessed downward to form an arc-shaped tire support surface. The top surface of the base is recessed downward to form an arc-shaped tire support surface, which can better contact and support the tire. The arc-shaped design matches the tire shape, providing a larger contact area and a more uniform support force. This can reduce the risk of tire deformation and damage and provide a more stable loading effect. Because the top surface of the base is recessed into an arc, the tire is easier and more stably embedded in the base during loading. This can reduce the possibility of tire sliding and shaking, and maintain the stability of the wheel during transportation. Reducing tire sliding and shaking can also reduce friction and impact between the wheel and the loading device, reducing potential damage and wear.

[0012] In the above-mentioned fixing device for fixing a passenger car on a flatbed cart, a vertically arranged support arm is provided on the base, and the clamping assembly includes two swing arms symmetrically arranged on the support arm, and the two swing arms are provided with clamping claws arranged in the length direction of the parking plate. The swing arms are an important component of the clamping assembly. They are installed on the support arms and have the function of swinging. Through the design of the swing arms, the clamping assembly can be flexibly adjusted and adapted to wheels of different sizes and types. The swinging movement of the swing arms can make the clamping claws contact and tighten with the wheels according to specific needs.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] 1. It has strong versatility. By adjusting the grille and the guide groove, the base position can be adjusted to be suitable for loading passenger cars with a wheelbase.

[0015] 2. It has high adjustment flexibility. The adjustment of the grille and the guide groove is simple and practical. The base can be adjusted to any position within the range through a sliding connection. It has a simple structure and a simple driving method.
