Detailed Description

The invention is described in detail below with reference to the drawings, which form a part hereof, and with reference to embodiments of the invention. However, it should be understood by those skilled in the art that the following examples are not intended to limit the technical solutions of the present invention, and all equivalent changes or modifications made in the spirit of the technical solutions of the present invention should be considered as falling within the protection scope of the present invention.

According to QCT699-2019 standard, the reliability is specified, the lifting tail plate for the vehicle does not have the phenomena of structural damage, permanent deformation, abnormal abrasion and the like (except easy damage) after no-load operation is 3000 times and load operation is 30000 times, and the lifting tail plate still has good operability; the regulation of the operation requirement is that the no-load operation requires that the tail plate can complete full-function operation according to the process sequence of a-b-c-d-e-f-g in the no-load state as shown in figure 1, and the tail plate is stable and coordinated without interference, jitter and clamping stagnation and abnormal noise, and the load operation requires that the tail plate can operate according to the process sequence of d-e-f-c-d as shown in figure 1 under the rated load and is stable and coordinated without interference, jitter and clamping stagnation and abnormal noise.

As shown in FIG. 1, the vehicle lifting tail plate comprises seven process positions a, b, c, d, e, f and g in the operation process. Wherein, the position a is that the tail plate is in a closed position; the position b is the position where the tail plate is opened and is level with the bottom surface of the carriage; the position c is the position where the tail plate falls down to land and is horizontal to the ground; the position d is a position where the tail plate continuously inclines downwards from the grounding position and is smoothly transited to the ground; the position e is a position where the tail plate is inclined upward from the position d to be in a horizontal state, and is in the same state as the position c; the position f is the position where the tail plate rises to be level with the bottom surface of the carriage, and is in the same state as the position b; the position g is a position where the tailgate rotates from the position f to the closed position, and is in the same state as the position a.

Based on the above, the utility model provides a vehicle crane tailboard reliability testing arrangement, as shown in fig. 2, include: a clamping portion 100 for fixing the lifting tail plate 10 for a vehicle; a driving part 200 for driving the hoisting tail plate 10 for the vehicle to circularly operate; a sensing part 300 which is provided in the vicinity of each specific position through which the lifting tail gate 10 for a vehicle passes during the circulation operation and senses the operation position of the lifting tail gate 10 for a vehicle; and a control unit 400 for controlling the connection between the driving unit 200 and the sensing unit 300, and controlling the driving unit 200 to drive the lifting tail plate 10 to circulate according to the reliability test requirement based on the sensing result of the sensing unit 300.

Specifically, the clamping portion 100 rotatably secures the vehicular jack tail panel 10 such that the vehicular jack tail panel 10 is rotatable about the clamping portion 100. As described above with reference to FIG. 1, the lifting and loading functions of the vehicle tailgate 10 are achieved by rotating the vehicle tailgate 10 such that the vehicle tailgate 10 is moved between the positions a-b-c-d-e-f-g as needed.

Further, the lifting yoke 10 for a vehicle is rotatably connected to the grip portion 100 by the driving portion 200. For example, the driving part 200 may include a connection mechanism 210, and the connection mechanism 210 may be rotatably connected to a proper position of the grip part 100 such that the connection mechanism 210 may rotate around the proper position of the grip part 100. The connecting mechanism 210 is simultaneously connected to the lifting tail plate 10 for a vehicle, so that the connecting mechanism 210 rotates around the clamping portion 100 and simultaneously drives the lifting tail plate 10 for a vehicle to rotate around the clamping portion 100. Specifically, referring to fig. 1, the connection mechanism 210 may rotate about the clamp portion 100 such that the truck tailgate 10 rotates from position b to position c or from position f to position g. On the other hand, the connecting mechanism 210 is rotatably connected to the vehicle lifting yoke 10, i.e., the vehicle lifting yoke 10 can rotate about the connecting mechanism 210. Specifically, referring to fig. 1, in the position a, in the case where the connection mechanism 210 does not rotate with respect to the clamping portion 100, the vehicle lifting tail 10 rotates downward with respect to the connection mechanism 210, so that the vehicle lifting tail 10 moves from the position a to the position b; alternatively, at position c, the vehicle lifting tailgate 10 is rotated downward relative to the connecting mechanism 210 without rotation of the connecting mechanism 210 relative to the clamping portion 100, such that the vehicle lifting tailgate 10 moves from position c to position d, or at position d, the vehicle lifting tailgate 10 is rotated upward relative to the connecting mechanism 210, such that the vehicle lifting tailgate 10 moves from position d to position e, or at position f, the vehicle lifting tailgate 10 is rotated upward relative to the connecting mechanism 210 without rotation of the connecting mechanism 210 relative to the clamping portion 100, such that the vehicle lifting tailgate 10 moves from position f to position g. That is, the driving unit 200 for driving the truck tailgate 10 to circulate is implemented by the connection mechanism 210. However, the present invention is not limited thereto, and the driving portion 200 may be implemented in other structures as long as the lifting yoke 10 for the vehicle can be driven to perform the circulation operation according to the reliability test requirement, for example, as shown in fig. 1, and the circulation operation may be performed between the position a to the position g.

Specifically, the sensing part 300 is provided in plurality. For example, using the example shown in fig. 1, the truck tailgate 10 experiences positions a through g during the cyclical motion. The position a is in the same state as the position g, the position b is in the same state as the position f, and the position c is in the same state as the position e. Therefore, in the present embodiment, the sensing part 300 includes a first sensing part 310, a second sensing part 320, a third sensing part 330 and a fourth sensing part 340. Wherein the first sensing part 310 is disposed near the position a and the position g to sense whether the lifting tail gate 10 for the vehicle is closed; the second sensing part 320 is disposed near the position b and the position f to sense whether the lifting tailgate 10 for the vehicle is opened to be level with the floor of the vehicle compartment; the third sensing part 330 is disposed near the position c and the position e to sense whether the lifting tail gate 10 for the vehicle is landed or not; the fourth sensing part 340 is disposed near the position d to sense whether the truck tailgate 10 is inclined downward and smoothly transits to the ground. It should be noted that the number and the arrangement position of the sensing parts 300 may be adjusted according to the shape and the type of the lifting yoke 10 for a vehicle.

In the present embodiment, the sensing part 300 may be provided as a photoelectric type proximity sensor. The photoelectric proximity sensor detects the presence or absence of an object by blocking or reflecting a light beam by the object to be detected and turning on a circuit by a synchronization circuit. The object to be detected is not limited to metal, and all objects capable of reflecting light (or having a light shielding effect) can be detected. Compared with other proximity sensors, the photoelectric proximity sensor has higher stability, longer service life and very small limit of detection distance. In the embodiment, the monitoring distance of the photoelectric proximity sensor can be adjusted within the range of 5-50cm, the situation that the position cannot be detected in place due to the limitation of the detection distance is avoided, and the position can be adjusted at will according to the test requirements. It should be noted that the present invention is not limited to the specific structure and type of the sensing portion 300.

Specifically, the control part 400 is electrically connected to the sensing part 300 and the driving part 200, and controls the driving part 200 to drive the lifting tail plate 10 for the vehicle to circularly operate according to the sensing result of the sensing part 300 and the reliability test requirement, so as to complete the reliability test of the lifting tail plate 10 for the vehicle.

Specifically, the input part 410 may be connected to the sensing part 300 to receive the sensing result of the sensing part 300, that is, the input part 410 may receive the operation state of the lifting yoke 10 for a vehicle sensed by the sensing part 300, for example, may receive the operation position of the lifting yoke 10 for a vehicle.

According to an embodiment, the control part 400 may further include a counter 440, and the counter 440 counts the number of times of the cycle operation of the lifting tail board for the vehicle according to the sensing result of the sensing part 300. For example, according to QCT699-2019 standards, the reliability of the vehicular lift gate 10 was tested by idle running 3000 times in the order of a-b-c-d-e-f-g and load running 30000 times in the order of d-e-f-c-d. The counter 440 may record the number of idle cycles plus 1 when the lifting tail board 10 for the vehicle completes the operation of a-b-c-d-e-f-g, or record the number of load cycles plus 1 when the lifting tail board 10 for the vehicle completes the operation of d-e-f-c-d, according to the sensing result of the sensing part 300. It should be noted that the counter 440 may be integrated with the processor 420 or may be provided separately from the processor 420.

According to one embodiment, the reliability testing device for the crane tail board for the vehicle further comprises a touch screen 500, and the touch screen 500 is in communication connection with the control part 400. Specifically, the touch screen 500 may be connected with the input part 410 of the control part 400 to receive the reliability test requirement through the touch screen 500.

The input part 410 may generate a control command according to the sensing result and the reliability test requirement input through the touch screen 500 after transmitting an input signal including the sensing result of the sensing part 300 and the reliability test requirement to the processor 420, and transmit the control command to the output part 430. Specifically, the processor 420 may generate a control command for controlling the driving part 200 with reference to the reliability test requirement with reference to the current position of the hoisting tailgate 10 for the vehicle sensed by the sensing part 300.

After the processor 420 receives the control command, it may control the driving part 200 to drive the lifting tail board 10 to circulate, so as to perform a reliability test experiment on the lifting tail board 10.

In addition, the counter 440 may synchronously count the number of the circulation operations of the lifting yoke 10 for a vehicle, and the number of the circulation operations may be displayed through the touch screen 500. In addition, during operation, the sensing part 300 senses the operation position of the lifting yoke 10 for the vehicle in real time, and displays the operation position of the lifting yoke 10 for the vehicle in real time through the touch screen 500.

In one embodiment, the controller 400 may also include a memory storing firmware, software, or programs that the processor 420 runs to perform the respective reliability tests. For example, experimental conditions corresponding to the requirements for reliability testing specified in the QCT699-2019 standard may be preset. At the beginning of a test experiment, processor 420 may call corresponding firmware, software, or programs stored in memory to automatically perform a reliability test.

According to one embodiment, the control unit 400 may be configured as a PLC, and the advantages of the PLC, such as high stability, strong anti-interference capability, small size, and light weight, may be fully utilized, and the PLC and the touch screen may be mutually matched to save hardware, such as a button and an intermediate relay, and save cost and installation space. The touch screen is in communication connection with the PLC, so that program contents of the touch screen and program contents of the PLC are correlated and matched with each other, the touch screen can be selected, for example, a test mode, test times and the stay time of the automobile lifting tail plate at each position, and the tail plate position is adjusted in a manual mode.

According to one embodiment, the output part may be a relay, and the relay controls the driving part 200 to realize stable operation of the lifting yoke for a vehicle in all directions.

Specifically, in this embodiment, Mitsubishi PLC (model: FX2N series) and Kunlun Tong touch screen (model: MCGS series) are used as main control cores, and 485 communication is adopted for interaction, and a preset program is used to correspond to the MCGS touch screen, so that the function of the touch screen for controlling the PLC is realized.

According to the utility model discloses an automobile-used jack-up tailboard reliability testing arrangement realizes following advantage:

the universality is high: the hoisting tail plates for the vehicles have various forms and different sizes, and a universal test device is manufactured and is difficult to meet various tail plate tests; if the test device is customized for each tail board, the test cost is inevitably increased, and a small burden is brought to enterprises.
