[0001] This utility model relates to the technical field of center-axle car carriers, specifically a center-axle car carrier. Background Technology

[0002] A center-axle car carrier is a special type of vehicle with its axle located in the middle. It is mainly used for transporting cars and can carry multiple cars at the same time. Compared with traditional semi-trailers, it is more efficient in transporting vehicles and has higher stability, thus improving transportation efficiency. In addition, the low chassis design makes it more stable during driving, improving the convenience of car transportation.

[0003] Because the connecting shaft of a center-axle car carrier is located in the center of the cargo box, the rear cargo box has a greater degree of freedom of movement. During vehicle operation, lane changes or tilting of the front of the vehicle can easily cause the rear cargo box to sway. This swaying reduces the stability of the cargo box and makes it prone to fishtailing, thus increasing the safety risks of vehicle operation. Utility Model Content

[0004] The purpose of this utility model is to provide a center-axle car carrier to solve the problem mentioned in the background art: during the operation of a center-axle car carrier, because the connection point between the two compartments is located in the central area of ​​the frame, the rear compartment has a large degree of freedom and range of rotation. Therefore, when the vehicle changes lanes or tilts its front end during operation, the rear compartment is prone to swaying and causing a fishtailing phenomenon, which greatly reduces the stability of the vehicle and increases the safety risks of driving the vehicle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a center-axle car carrier, including a car body, a connecting frame provided at the end of the car body, a connecting component for connecting the car body provided outside the connecting frame, the connecting component including a mounting frame provided outside the connecting frame, a limiting groove provided on the inner wall of the mounting frame, a drive shaft provided on the inner wall of the limiting groove, a support frame provided inside the limiting groove, a linkage shaft provided on the inner side of the support frame, and a plug rod provided inside the linkage shaft;

[0006] The inner wall of the limiting groove is provided with multiple embedded tubes, and each of the multiple embedded tubes is provided with a pressure plate.

[0009] Preferably, one end of the linkage shaft is connected to the outer wall of the support frame, and the other end is embedded in the drive shaft and rotatably connected to the inner wall of the drive shaft through a bearing. The insertion rod is located inside the linkage shaft and is slidably connected to the inner wall of the linkage shaft, and can be inserted into the drive shaft through sliding.

[0010] Preferably, a plurality of the embedded tubes are arranged in a ring on the inner wall of the limiting groove and are embedded and connected to the inner wall of the limiting groove. The pressure plate is connected to the inner wall of the embedded tubes and electrically connected to the insertion rod and the drive shaft.

[0011] Preferably, the cavity is distributed inside the support frame, one end of the connecting rod is located inside the cavity and is slidably connected to the inner wall of the cavity, and the other end is connected to the protrusion. The two ends of the spring are respectively connected to the inner wall of the cavity and the protrusion.

[0012] Preferably, a telescopic plate is provided inside the top support plate of the carriage. The telescopic plate is embedded inside the support plate and is slidably connected to the inner wall of the support plate via an electrically controlled slide rail.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting an installation frame at the connection of two carriages, and connecting the two carriages to the installation frame and the support frame inside the installation frame respectively, the two carriages can be hinged through the installation frame and the support frame. A drive shaft is set inside the installation frame, and the support frame switches between a rotary connection and a coaxial connection with the drive shaft through a linkage shaft and a plug rod. The drive shaft can pull and correct when the carriages swing, reducing the swing amplitude of the carriages and improving the stability of the carriage connection.

[0015] 2. By setting multiple embedded tubes on the inner wall of the mounting frame and setting retractable protrusions on the outside of the support frame, when the support frame rotates with the mounting frame, the protrusions on the outside of the support frame can be inserted into the embedded tubes and activated by pressing against the pressure plate inside the embedded tubes. The multiple embedded tubes and pressure plate can help detect the rotation angle between the two carriages, thereby improving the driver's understanding of the carriage angle information and facilitating the driver's operation.

[0016] This invention can detect the angle between two carriages, improving the driver's understanding of the carriage information. Furthermore, when the carriage angle deviation is too large, it can correct the angle by reverse driving through the drive shaft, thereby improving the stability of the carriage.

The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0024] Please see Figure 1 and Figure 2 A center-axle car carrier includes a car body 1. A connecting frame 2 is provided at the end of the car body 1. The connecting frame 2 can connect the car body 1 to a mounting frame 3. A connecting component for connecting the car body 1 is provided on the outside of the connecting frame 2. The connecting component includes a mounting frame 3 provided on the outside of the connecting frame 2. A limiting groove 301 is provided on the inner wall of the mounting frame 3 to limit the space in which the support frame 5 and the mounting frame 3 can rotate. A drive shaft 4 is provided on the inner wall of the limiting groove 301. The drive shaft 4 can generate a rotational driving force through electronic control, thereby driving the support frame 5 and the mounting frame 3 to rotate. The support frame 5 is provided inside the limiting groove 301. A linkage shaft 501 is provided on the inner side of the support frame 5 to connect the support frame 5 and the drive shaft 4. A plug rod 502 is provided inside the linkage shaft 501. The plug rod 502 can extend and retract within the linkage shaft 501 and can be inserted into the drive shaft 4 through extension and retraction to connect the linkage shaft 501 and the drive shaft 4.

[0025] One end of the connecting frame 2 is connected to the end of the carriage 1. The other end of the connecting frame 2 of one carriage 1 is connected to the mounting frame 3 by bolts. The other end of the connecting frame 2 of the other carriage 1 is connected to the support frame 5 by a fixed shaft. The support frame 5 is located in the limiting groove 301 on the inner wall of the mounting frame 3 and is rotatably connected to the inner wall of the limiting groove 301. The drive shaft 4 is embedded in the inner wall of the limiting groove 301 and is rotatably connected to the inner wall of the limiting groove 301. One end of the linkage shaft 501 is connected to the outer wall of the support frame 5, and the other end is embedded in the drive shaft 4 and is rotatably connected to the inner wall of the drive shaft 4 by bearings. The insertion rod 502 is located inside the linkage shaft 501 and is slidably connected to the inner wall of the linkage shaft 501, and can be inserted into the drive shaft 4 by sliding.

[0026] Specifically: During use, the connecting frame 2 on the outside of the two carriages 1 is connected to the mounting frame 3 and the support frame 5 respectively. In normal state, the linkage shaft 501 on the outside of the support frame 5 is rotatably connected to the drive shaft 4, so the two carriages 1 can rotate flexibly. When the rotation angle between the two carriages 1 exceeds the set value, the plug rod 502 is slidably extended and retracted in the linkage shaft 501 and embedded in the drive shaft 4 through electronic control. At the same time, the drive shaft 4 is controlled to rotate, and together with the support frame 5, it drives the rear carriage 1 and the mounting frame 3 to rotate, thereby correcting the angle of the carriages 1 and improving the stability of the two carriages 1.

[0027] Please see Figures 2-4 The inner wall of the limiting groove 301 is provided with multiple embedded tubes 6, which correspond to different rotation angles of the support frame 5 and the mounting frame 3. Each of the multiple embedded tubes 6 is provided with a pressure plate 601. The outer wall of the support frame 5 is provided with a cavity 7, which can accommodate the connecting rod 702 and the protrusion 8 and position their sliding angle. The cavity 7 is provided with a spring 701 and a connecting rod 702. The spring 701 can support the protrusion 8 and push the protrusion 8 to extend out of the cavity 7. One end of the connecting rod 702 is provided with a protrusion 8.

[0028] Multiple embedded tubes 6 are distributed in a ring on the inner wall of the limiting groove 301 and are embedded and connected to the inner wall of the limiting groove 301. The pressure plate 601 is connected to the inner wall of the embedded tubes 6 and electrically connected to the insertion rod 502 and the drive shaft 4. The cavity 7 is distributed inside the support frame 5. One end of the connecting rod 702 is located in the cavity 7 and is slidably connected to the inner wall of the cavity 7. The other end is connected to the protrusion 8. The two ends of the spring 701 are connected to the inner wall of the cavity 7 and the protrusion 8, respectively.

[0029] Specifically: When the two carriages 1 rotate, they will drive the support frame 5 to rotate within the mounting frame 3. In the normal state, the protrusion 8 in the cavity 7 of the outer wall of the support frame 5 is compressed and contracted within the cavity 7. When the support frame 5 and the mounting frame 3 rotate so that the cavity 7 corresponds to the position of the embedded tube 6 in the limiting groove 301, the spring 701 pushes the protrusion 8 into the embedded tube 6 and presses the pressure plate 601 in the embedded tube 6 to trigger, thereby controlling the switching operation of the insertion rod 502 and the drive shaft 4.

[0030] Please see Figure 1 The top support plate of the carriage 1 is equipped with a telescopic plate 9. The telescopic plate 9 is embedded in the support plate and is slidably connected to the inner wall of the support plate through an electrically controlled slide rail. The length of the support plate can be extended by sliding the telescopic plate 9 inside the top support plate of the carriage 1, so as to meet the needs of car placement or loading and unloading. The second-layer support plate is hydraulically driven and cooperates with the hydraulic cylinder hidden in the main beam. The telescopic plate 9 can be slidably extended and retracted in the slide rail of the second-layer platform through hydraulic control.
