[0009] A parking platform, arranged on the bottom plate;

[0010] A wheel locking assembly, arranged on one side of the bottom plate, comprising a retaining bar and a chain drive mechanism. The chains of the chain drive mechanism are distributed at the left and right ends of the bottom plate. The chains of the chain drive mechanism are arranged in the front and rear directions. The retaining bar is arranged in the left and right directions and is driven by the chain drive mechanism. After the chain drive mechanism drives the retaining bar to turn downwards, the retaining bar is flush with or lower than one end of the parking platform, so that the vehicle tail can be reversed onto the parking platform. After the chain drive mechanism drives the retaining bar to turn upwards, the retaining bar slides along the upper surface of the parking platform, so that the retaining bar is inserted between the wheel and the parking platform.

[0011] Further, it includes a pair of vehicle stoppers, arranged on the left and right sides at the front end of the bottom plate.

[0012] Further, it includes a pair of scissor mechanisms disposed on the left and right sides at the rear end of the base plate. The scissor mechanisms are oppositely arranged and can clamp the rear of the vehicle after being pushed out.

[0013] Further, the number of the wheel locking components is two groups. The two chain drive mechanisms are arranged in sequence front and back. After one of the bars is turned down, it is flush with or lower than the front end of the parking platform, and after the other bar is turned down, it is flush with or lower than the rear end of the parking platform.

[0014] Further, it includes an uphill ramp disposed at the front end of the base plate.

[0015] Further, the uphill ramp is spaced from the parking platform, and the space between the uphill ramp and the parking platform forms a receiving groove. After one of the bars is turned down, it is received in the receiving groove.

[0018] Therefore, the present utility model provides the following effects and / or advantages:

[0019] In this application, when there is the rear of a vehicle on the parking platform, the wheels at the rear of the vehicle are in contact with the parking platform. At this time, when the bar is turned up and moves in the front-back direction on the parking platform, the bar can be inserted between the wheel and the parking platform, thereby forming a certain extrusion on the wheel and clamping the wheel so that the wheel cannot rotate, forming a locking effect on the wheel.

[0020] In this application, by providing a ramp and spacing the ramp from the parking platform, a receiving groove for receiving the bar is formed. This structure can enable the vehicle to better receive the bar in the turned-down state, and the receiving groove can serve as an avoidance structure for the turned-down bar, enabling the bar to be smoothly received.

[0021] This application is provided with scissor mechanisms, which can apply clamping forces on both sides of the vehicle, can fix the left and right positions of the rear of the vehicle after parking, and prevent the vehicle from moving left and right.

[0027] For the convenience of those skilled in the art to understand, the structure of the present utility model will be further described in detail below in conjunction with the drawings for the embodiments:

[0028] Embodiment 1

[0029] Referring to Figures 1-3 , a vehicle tail positioning device with stable parking includes:

[0030] A bottom plate 1;

[0031] A parking platform 2, which is arranged on the bottom plate 1;

[0032] In this embodiment, the bottom plate 1 can be fixed to the ground by expansion bolts, and the parking platform 2 is arranged on the bottom plate 1. The tail of the vehicle (such as a trailer) is reversed and parked on the parking platform 2.

[0033] A wheel locking assembly 3, which is arranged on one side of the bottom plate 1 and includes a stop bar 301 and a chain drive mechanism 302. The chain 3021 of the chain drive mechanism 302 is distributed at the left and right ends of the bottom plate 1. A part of the chain 3021 is driven by a servo motor 3023. The chain 3021 of the chain drive mechanism 302 is arranged in the front-back direction. The stop bar 301 is arranged in the left-right direction and is driven by the chain drive mechanism 302. After the chain drive mechanism 302 drives the stop bar 301 to turn down, the stop bar 301 is flush with or lower than one end of the parking platform 2, so that the tail of the vehicle can be reversed onto the parking platform 2. After the chain drive mechanism 302 drives the stop bar 301 to turn up, the stop bar 301 slides along the upper surface of the parking platform 2, so that the stop bar 301 is inserted between the wheel and the parking platform 2.

[0034] In this embodiment, the chain 3021 of the chain drive mechanism 302 is distributed on the left and right sides of the bottom plate 1. The stop bar 301 is connected between the chains 3021. The chains 3021 are supported by corresponding sprockets 3022, and one of the sprockets is power-connected to the servo motor 3023, thereby forming a transmission structure. When the servo motor 3023 operates, it can drive the stop bar 301 to move back and forth. When there is a vehicle tail on the parking platform 2, the wheels at the vehicle tail contact the parking platform 2. At this time, when the stop bar 301 flips up and moves back and forth on the parking platform 2, the stop bar 301 can be inserted between the wheel and the parking platform 2, thereby forming a certain extrusion on the wheel and clamping the wheel to prevent the wheel from rotating, forming a locking effect on the wheel.

[0035] Moreover, when the stop bar 301 flips down, the stop bar 301 can be hidden or stored at the front and rear ends of the parking platform 2, so as to facilitate the vehicle tail to drive into or out of the parking platform 2.

[0036] In this embodiment, the chain drive mechanism 302 is used to drive the stop block 301. The movement path of the chain 3021 on the sprocket 3022 is circular arc, so as to realize the flipping up or down action of the stop bar 301 at this position. After the stop bar 301 flips down, it can be flush with or lower than one end of the parking platform. At this time, the stop bar 301 avoids the wheel, facilitating the wheel to pass through the parking platform 2.

[0037] Further, it includes a pair of vehicle stoppers 4, which are arranged on the left and right sides at the front end of the bottom plate 1.

[0038] In this embodiment, the vehicle stopper 4 can limit the driving direction and driving width of the vehicle tail, facilitating the driver to reverse the vehicle onto the device.

[0039] Further, it includes a pair of scissor mechanisms 5, which are arranged on the left and right sides at the rear end of the bottom plate 1. The scissor mechanisms 5 are arranged oppositely, and the vehicle tail can be clamped after the scissor mechanisms 5 are pushed out.

[0040] After the scissor mechanism 5 is pushed out, it can clamp the vehicle tail. During the process of straightening the vehicle tail, it can assist in adjustment and reduce the driving force required by the parking platform driving part 202. Moreover, when the vehicle tail is straightened, by clamping the left and right ends of the vehicle tail through the scissor mechanism 5, the vehicle can be kept stable in the left and right directions during parking, preventing the vehicle from running off course.

[0041] Further, the number of the wheel locking assemblies 3 is two groups. The two chain drive mechanisms 302 are arranged in sequence front and back. After one of the stop bars 301 flips down, it is flush with or lower than the front end of the parking platform 2, and after the other stop bar 301 flips down, it is flush with or lower than the rear end of the parking platform 2.

[0042] In this embodiment, the number of the wheel locking assemblies 3 can be one group, preferably two groups.

[0043] If the number of the wheel locking assemblies 3 is one group, after the retaining bar 301 is turned downwards, it is flush with or lower than the front end of the parking platform 2. After the retaining bar 301 is turned upwards, it moves from the front end to the rear end of the parking platform 2. This structure enables the retaining bar to be inserted into the front end of the wheel because generally, after the rear of the vehicle abuts against or approaches the loading equipment, during the loading process of the loading equipment, the goods entering and leaving the vehicle can easily cause the vehicle to shift forward. At this time, the retaining bar 301 is inserted and clamped at the front end of the vehicle wheel to prevent the vehicle from shifting forward.

[0044] If the number of the wheel locking assemblies 3 is two groups, after the retaining bars 301 are turned downwards, they are respectively flush with or lower than the front end and the rear end of the parking platform 2. After the retaining bars 301 are turned upwards, they are inserted between the wheel and the parking platform 2 in a front-back clamping manner, which can better prevent the vehicle from shifting forward.

[0045] Further, it includes an uphill ramp 5, which is arranged at the front end of the bottom plate 1. The uphill ramp 5 can enable the vehicle to drive onto the parking platform 2 more smoothly.

[0046] Further, the uphill ramp 5 is arranged at a distance from the parking platform 2, and the space between the uphill ramp 5 and the parking platform 2 forms a receiving groove, and one of the retaining bars 301 is received in the receiving groove after being turned downwards.

[0047] This structure can enable the vehicle to better receive the retaining bar 301 in the turned-down state, and the receiving groove can serve as an avoidance structure for the retaining bar 301 after it is turned downwards, enabling the retaining bar 301 to be smoothly received.

[0048] Further, the cross-section of the retaining bar 301 is a square structure. The square structure can better be clamped at the bottom of the wheel.

[0049] Further, the chain drive mechanism 302 includes a servo motor 3023, and the working mode of the servo motor 3023 is the torque mode.

[0050] In this embodiment, the output power of the motor 3023 is detected by using the torque mode of the servo motor, so as to judge whether the retaining bar 301 is inserted between the wheel and the parking platform 2, and the torque upper limit value is defined to clamp the wheel.
