Description

Technical Field

[0001] The present invention relates to the field of auxiliary straightening devices, and in particular to an auxiliary straightening device for the rear of a vehicle and a control method thereof. Background Art

[0002] When loading and unloading a vehicle, it is necessary to reverse the vehicle and dock it with the automated loading equipment. After docking, the rear of the vehicle needs to be aligned with the automated loading equipment, that is, the rear of the vehicle needs to be straightened so that the goods on the automated loading equipment or the transport cart can smoothly enter the vehicle.

[0003] In the prior art, the rear end of a vehicle is generally straightened by manually reversing. This method requires high reversing skills from the driver, and often requires the driver to adjust the angle and distance of the rear end of the vehicle multiple times to accurately connect to the automated loading equipment. Alternatively, as in the prior patent with application number 202321561779.5, which is named an auxiliary vehicle alignment platform, the disclosed vehicle alignment platform can adjust the left and right positions of the slide plate through a cylinder to straighten the rear end of the vehicle. However, on the one hand, the prior equipment uses a cylinder, and the liquid in the cylinder exhibits different expansion coefficients at different temperatures. After straightening, as the temperature of the liquid in the cylinder changes, the extension amount of the cylinder will gradually change, causing the rear end of the vehicle to be misaligned. In addition, the platform cannot lock the front and rear position of the rear end of the vehicle. During the loading and unloading process, the vehicle is subjected to the force of the automated loading equipment, and the vehicle is prone to move in the front and rear directions.

[0004] The purpose of the present invention is to design a vehicle rear auxiliary straightening device and a control method thereof in response to the above-mentioned problems in the prior art. Summary of the Invention

[0005] In response to the problems existing in the above-mentioned prior art, the present invention provides a vehicle rear auxiliary straightening device and a control method thereof, which can effectively solve at least one problem existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A vehicle rear auxiliary straightening device, comprising:

[0008] base plate;

[0009] A left-right straightening assembly is provided on the left side of the base plate, comprising a slide plate and a slide plate driving member, wherein the slide plate is provided on the base plate so as to be movable left and right, and the slide plate driving member is used to drive the slide plate to move left and right;

[0010] The wheel locking assembly is arranged on the right side of the base plate, and includes a gear bar and a chain transmission mechanism. The chain of the chain transmission mechanism is arranged in the front-to-back direction, and the gear bar is arranged in the left-to-right direction and is driven by the chain transmission mechanism. After the chain transmission mechanism drives the gear bar to flip down, the gear bar is flush with or lower than one end of the skateboard, so that the rear end of the vehicle can fall onto the skateboard. After the chain transmission mechanism drives the gear bar to flip up, the gear bar slides along the upper surface of the skateboard, so that the gear bar is inserted between the wheel and the skateboard.

[0011] Furthermore, it includes a pair of car stoppers, which are arranged on the left and right sides of the front end of the base plate.

[0012] Furthermore, it includes a pair of scissor-type mechanisms, which are arranged on the left and right sides of the rear end of the base plate. The scissor-type mechanisms are arranged opposite to each other, and can clamp the rear end of the vehicle after being pushed out.

[0013] Furthermore, there are two groups of wheel locking assemblies, and the two chain drive mechanisms are arranged in sequence front and back, one of the gear bars is flush with or lower than the front end of the skateboard after being folded down, and the other gear bar is flush with or lower than the rear end of the skateboard after being folded down.

[0014] Furthermore, it includes an ascending ramp, which is arranged at the front end of the base plate.

[0015] Furthermore, the upward ramp and the slide are spaced apart, and the space between the upward ramp and the slide forms a receiving groove, wherein one of the gear bars is folded down and stored in the receiving groove.

[0016] Furthermore, the chain transmission mechanism includes a plurality of sprockets, one of which is arranged at a position corresponding to the front end and / or rear end of the skateboard, and the diameter of the sprocket is the same as the distance between the skateboard and the base plate.

[0017] Furthermore, the bottom plate is provided with a plurality of guide rails, and the bottom end of the slide plate is provided with a wear-resistant block corresponding to the guide rails, and the guide rails limit the movement direction of the wear-resistant block to the left and right direction.

[0018] Furthermore, the skateboard driving member includes a bidirectional screw rod assembly arranged along the front-back direction, and the bidirectional screw rod assembly drives an eight-shaped connecting rod, one end of which is connected to the skateboard.

[0019] A control method for a vehicle rear auxiliary straightening device is further provided. Based on the vehicle rear auxiliary straightening device, the method comprises the following steps:

[0020] Controlling the chain transmission mechanism to drive the gear bar to turn downward;

[0021] In response to the rear end of the vehicle being reversed and parked on the slide, controlling the slide drive member to drive the slide to move left and right so that the rear end of the vehicle is aligned with the corresponding loading equipment;

[0022] The chain transmission mechanism is controlled to drive the gear bar to turn up, so that the gear bar is inserted between the wheel and the skateboard, so that the vehicle is locked in the front and rear directions.

[0023] Therefore, the present invention provides the following effects and / or advantages:

[0024] The present application provides a vehicle straightening device for assisting in the alignment of the rear end of a trailer. By automatically adjusting the angle of the rear end of the vehicle, it achieves automatic adjustment and docking with the automatic loading equipment, ensuring that the automatic loading equipment does not move and directly straightens the trailer, achieving the advantage of one-time reversing and straightening docking.

[0025] In the present application, when there is a rear end of a vehicle on the skateboard, the wheels at the rear end of the vehicle contact the skateboard. At this time, when the gear bar flips up and moves in the front and rear directions on the skateboard, the gear bar can be inserted between the wheel and the skateboard, thereby forming a certain degree of squeezing on the wheel and clamping the wheel, making the wheel unable to rotate, thereby forming a locking effect on the wheel.

[0026] The present invention provides a ramp, and the distance between the ramp and the slide plate is set to form a receiving groove for storing the gear bar. This structure can better store the gear bar in the downward state of the vehicle, and the receiving groove can serve as a avoidance structure after the gear bar is folded down, so that the gear bar can be stored smoothly.

[0027] The present application is provided with a scissor mechanism, which can clamp and apply force on both sides of the vehicle. On the one hand, it can assist the skateboard drive component in applying force synchronously, and on the other hand, it can fix the left and right positions of the rear end of the vehicle after parking to prevent the vehicle from moving.

[0028] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention are realized and obtained by the structures particularly pointed out in the description and the drawings.

[0029] It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments and the accompanying drawings:

[0036] refer to Figure 1-3 , a vehicle rear auxiliary straightening device, comprising:

[0037] Base plate 1;

[0038] The left and right straightening assembly 2 is arranged on the left side of the base plate 1, and includes a slide plate 201 and a slide plate driving member 202. The slide plate 201 is arranged on the base plate 1 so as to be movable left and right. The slide plate driving member 202 is used to drive the slide plate 201 to move left and right.

[0039] In this embodiment, the base plate 1 can be fixed to the ground by expansion bolts, and the slide 201 is slidably set on the base plate 1. When the rear end of a vehicle (such as a trailer) is reversed and parked on the slide 201, the slide drive 202 drives the slide 201 to move left and right to adjust the left and right position of the rear end of the vehicle. At this time, the front of the vehicle does not move, and the vehicle can be in neutral, thereby adjusting the angle between the vehicle and the loading equipment to align the loading equipment.

[0040] The wheel locking assembly 3 is arranged on the right side of the base plate 1, and includes a stop bar 301 and a chain transmission mechanism 302. The chain 3021 of the chain transmission mechanism 302 is arranged in the front-to-back direction, and the stop bar 301 is arranged in the left-to-right direction and is driven by the chain transmission mechanism 302. After the chain transmission mechanism 302 drives the stop bar 301 to flip down, the stop bar 301 is flush with or lower than one end of the skateboard 201, so that the rear end of the vehicle can fall onto the skateboard 201. After the chain transmission mechanism 302 drives the stop bar 301 to flip up, the stop bar 301 slides along the upper surface of the skateboard 201, so that the stop bar 301 is stuffed between the wheel and the skateboard 201.

[0041] In this embodiment, the chains 3021 of the chain drive mechanism 302 are distributed on the left and right sides of the base plate 1, and the gear bars 301 are connected between the chains 3021. The chains 3021 are supported by corresponding sprockets 3022, one of which is powered by a motor 3023, thereby forming a transmission structure. When the motor 3023 is in operation, it can drive the gear bars 301 to move back and forth. When a vehicle rears up on the skateboard 201, the rear wheel of the vehicle contacts the skateboard 201. At this time, when the gear bars 301 flip up and move forward and backward on the skateboard 201, the gear bars 301 can be inserted between the wheel and the skateboard 201, thereby exerting a certain pressure on the wheel and locking the wheel so that the wheel cannot rotate, thus forming a locking effect on the wheel.

[0042] Furthermore, when the stop bar 301 is flipped down, the stop bar 301 can be hidden or stored at the front and rear ends of the slide plate 201 , thereby facilitating the rear end of a vehicle to enter or exit the slide plate 201 .

[0043] The motor 3023 of this embodiment is a servo motor, and the output power of the motor 3023 is detected by using the torque mode of the servo motor to determine whether the gear bar 301 is inserted between the wheel and the skateboard 201, and to limit the upper limit of the torque to clamp the wheel.

[0044] This embodiment uses a chain transmission mechanism 302 to drive the block 301. The movement path of the chain 3021 on the sprocket 3022 is an arc, so that the block 301 can be flipped down or up at this location. After flipping down, the block 301 can be flush with or lower than one end of the skateboard. At this time, the block 301 avoids the wheel, making it easier for the wheel to pass through the skateboard 201.

[0045] Furthermore, a pair of vehicle stoppers 4 are provided on the left and right sides of the front end of the base plate 1 .

[0046] In this embodiment, the vehicle stopper 4 can limit the driving direction and driving width of the rear end of the vehicle, making it convenient for the driver to back the vehicle onto the device.

[0047] Furthermore, it includes a pair of scissor-type mechanisms 5, which are arranged on the left and right sides of the rear end of the base plate 1. The scissor-type mechanisms 5 are arranged opposite to each other, and the scissor-type mechanisms 5 can clamp the rear end of the vehicle after being pushed out.

[0048] The scissor mechanism 5 can clamp the rear of the vehicle after being extended, and can assist in the adjustment process during the straightening process of the vehicle's rear end, thereby reducing the driving force required by the slide plate drive member 202. Furthermore, after the rear of the vehicle is straightened, the scissor mechanism 5 clamps the left and right ends of the rear of the vehicle, thereby maintaining the vehicle's parking stability in the left and right directions and preventing the vehicle from deviating.

[0049] Furthermore, the number of the wheel locking assemblies 3 is two groups, and the two chain transmission mechanisms 302 are arranged in sequence front and back, one of the gear bars 301 is flush with or lower than the front end of the skateboard 201 after being folded down, and the other gear bar 301 is flush with or lower than the rear end of the skateboard 201 after being folded down.

[0050] In this embodiment, the number of the wheel locking assemblies 3 can be one group, preferably two groups.

[0051] If the number of wheel locking assemblies 3 is one group, the stop bar 301 will be flush with or lower than the front end of the slide plate 201 after being folded down, and will move from the front end to the rear end of the slide plate 201 after being folded up. This structure allows the stop bar to be inserted from the front end of the wheel. This is because the rear end of the vehicle is aligned with the loading equipment, and the rear end of the vehicle is generally against or close to the loading equipment. During the loading process of the loading equipment, the goods entering and exiting the vehicle can easily cause the vehicle to shift forward. At this time, the stop bar 301 is inserted and engaged at the front end of the vehicle wheel to prevent the vehicle from shifting forward.

[0052] If there are two wheel locking assemblies 3, the stop bars 301 are flush with or lower than the front and rear ends of the skateboard 201 after being folded down. After being folded up, the stop bars 301 are inserted between the wheel and the skateboard 201 in a front-to-rear clamping manner, which can better prevent the vehicle from shifting forward.

[0053] Furthermore, an up ramp 5 is provided at the front end of the base plate 1. The up ramp 5 can enable a vehicle to drive onto the slide plate 201 more smoothly.

[0054] Furthermore, the upward ramp 5 and the slide 201 are spaced apart from each other, and the space between the upward ramp 5 and the slide 201 forms a receiving groove, wherein one of the stop bars 301 is folded down and stored in the receiving groove.

[0055] This structure can enable the vehicle to better store the gear bar 301 in the folded-down state, and the accommodating groove can serve as an avoidance structure after the gear bar 301 is folded down, so that the gear bar 301 can be stored smoothly.

[0056] Furthermore, the chain transmission mechanism 302 includes several sprockets 3022, wherein one sprocket 3022 is arranged at a position corresponding to the front end and / or rear end of the skateboard 201, and the diameter of the sprocket 3022 is the same as the distance between the skateboard 201 and the base plate 1.

[0057] In this embodiment, the sprocket 3022 is arranged at a position corresponding to the front end and / or rear end of the skateboard 201, so that the stop bar 301 can be transported to the front end and / or rear end of the skateboard 201. At the same time, the diameter of the sprocket 3022 is the same as the distance between the skateboard 201 and the base plate 1, so that the stop bar 301 can move along the upper surface of the skateboard 201 after being flipped up, and can be completely received in the receiving groove after being flipped down, preventing the stop bar 301 from protruding from the skateboard 201.

[0058] Furthermore, the bottom plate 1 is provided with a plurality of guide rails 101 , and the bottom end of the slide plate 201 is provided with a wear-resistant block 2011 corresponding to the guide rails 101 , and the guide rails 101 limit the movement direction of the wear-resistant block 2011 to the left and right direction.

[0059] Through the guide rail 101 and wear-resistant block 2011 of this structure, specifically, the wear-resistant block 2011 is a PE wear-resistant block, and the PE wear-resistant plate is provided with an oil groove, which can increase lubrication and reduce friction. The top of multiple wear-resistant blocks 2011 covers the slide 201, and a heavy-loaded universal ball can also be added to the slide 201 to ensure the sliding of the slide 201.

[0060] Furthermore, the skateboard driving member 202 includes a bidirectional screw assembly 201 arranged along the front-to-back direction. The bidirectional screw assembly 2021 drives an eight-shaped connecting rod 2022, and one end of the connecting rod 2022 is connected to the skateboard 201.

[0061] The slide plate 201 is connected via a connecting rod 2022 , and the connecting rod 2022 is provided on a slider of a bidirectional screw assembly 2021 .

[0062] In this embodiment, a bidirectional screw assembly 2021 drives the opening and closing of a figure-eight connecting rod 2022, thereby adjusting the left and right positions of one end of the connecting rod 2022, and thus driving the movement of the slide 201. Furthermore, this embodiment replaces the conventional hydraulic cylinder as a driving element with a bidirectional screw assembly 201, which does not contain liquid and thus does not deviate at different temperatures. Furthermore, the bidirectional screw assembly 201 is highly precise, allowing precise control of the position of the slide 201.

[0063] This embodiment may also include a communication system, so that each component can be controlled by remote control or a server, intelligent terminal, etc.

[0064] A control method for a vehicle rear auxiliary straightening device is further provided. Based on the vehicle rear auxiliary straightening device, the method comprises the following steps:

[0065] S1, controlling the chain transmission mechanism 302 to drive the gear bar 301 to turn downward;

[0066] S2, in response to the rear end of the vehicle being reversed and parked on the slide 201, controlling the slide drive 202 to drive the slide 201 to move left and right so that the rear end of the vehicle is aligned with the corresponding loading equipment;

[0067] When the vehicle is reversed and parked on the slide plate 201, if the vehicle body is at an angle to the automatic loading system, the slide plate 201 can be translated left and right. By driving the sliding plate 201 to move left and right, the left and right position of the rear end of the vehicle can be adjusted, thereby adjusting the angle between the rear end of the vehicle and the loading equipment to align them.

[0068] Furthermore, after executing step S2, the following steps may be continued: the scissor mechanism 5 is controlled to be pushed out, thereby fixing the left and right positions of the rear end of the vehicle. The scissor mechanism 5 is pushed out to support the truck body so that the truck body does not rock left and right when loading.

[0069] Furthermore, during the execution of step S2, the following operations may also be performed: the scissor lift mechanism 5 is pushed out to assist in driving the rear end of the vehicle to move left and right.

[0070] S3, controlling the chain transmission mechanism 302 to drive the stop bar 301 to flip upward, so that the stop bar 301 is inserted between the wheel and the skateboard 201, so that the vehicle is locked in the front-rear direction.

[0071] The stop bar 301 blocks the front and rear wheels from moving forward and backward when loading.

[0072] The working status at this time is Figure 4-5 As shown, the vehicle is locked in the front and rear directions and the left and right directions at this time, and the vehicle will not shift during the loading process.

[0073] After loading is completed, the scissor mechanism 5 is retracted, the front and rear wheel blocking bars 301 are turned down, and the vehicle moves out.
