DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of the present utility model.

[0023] An embodiment provided by the present utility model is shown in the accompanying drawings as follows: Figure 1 A trackless rubber-tyred vehicle automatic parking device, comprising a safety belt assembly 1, a safety belt anti-explosion sensor 2, a logic judgment module 3, an execution parking module 4, a hand brake execution mechanism 5, a hand brake operating mechanism 6, a brake disc 7 and a torque sensor 8.

[0024] The safety belt anti-explosion sensor 2 and the torque sensor 8 are installed on the safety belt assembly 1, and the output ends of the safety belt anti-explosion sensor 2 and the torque sensor 8 transmit electrical signals to the logic judgment module 3, which transmits the electrical signals to the execution parking module 4 after judgment, and the execution parking module 4 transmits execution commands to the hand brake execution mechanism 5. The execution parking module 4 is arranged between the hand brake operating mechanism 6 and the hand brake execution mechanism 5.

[0025] As shown in the accompanying drawings, Figure 2 , Figure 3 and Figure 4 , the safety belt assembly 1 comprises a safety belt clamping piece 11, a safety belt insert 12 and a connecting belt 13, the safety belt clamping piece 11 comprises a shell 111 and a movable piece 112, the movable piece 112 further comprises a pressing block 1121, a top sheet 1122, a bottom sheet 1123, a limiting block 1124 and a sensor connecting piece 1125, and the safety belt insert 12 comprises a connecting belt fixing ring 121 and an insert 122.

[0026] The movable piece 112 moves up and down relative to the shell 111, the pressing block 1121 passes through the surface groove hole of the shell 111 and connects the top sheet 1122 inside the shell 111, the outer diameter of the top sheet 1122 is larger than the surface groove hole of the shell 111, a spring 113 is arranged between the top sheet 1122 and the bottom of the shell 111, the bottom sheet 1123 is connected below the top sheet 1122, the sensor connecting piece 1125 is installed on the bottom sheet 1123, and the limiting block 1124 is further arranged on the bottom sheet 1123.

[0027] The safety belt explosion-proof sensor 2 is a contact sensor, and the receiving end thereof is arranged inside the shell 111 and corresponds to above the sensor contact piece 1125. The sensor contact piece 1125 of the movable piece 112 is in contact with the receiving end of the safety belt explosion-proof sensor 2 in two states of contact and non-contact. The safety belt explosion-proof sensor 2 is arranged at the position of the shell 111 and is not affected in the normal inserting process of the safety belt.

[0028] As shown in Figure 5 , when the tab 122 of the safety belt insert 12 is inserted into the safety belt clamping piece 11, the tab 122 first abuts against the inclined surface of the limiting block 1124, and with the tab 122 being pushed inward, the bottom piece 1123 moves downward together with the movable piece 112 as a whole at this time, the limiting block 1124 is embedded into the hole of the tab 122 to limit the tab 122, the safety belt insert 12 is fixed by the safety belt clamping piece 11, and at this time, the sensor contact piece 1125 on the movable piece 112 is in a non-contact state with the receiving end of the safety belt explosion-proof sensor 2 inside the shell 111.

[0029] As shown in Figure 6 , when the safety belt insert 12 is taken out of the safety belt clamping piece 11, the pressing block 1121 is pressed downward, the surface height of the limiting block 1124 is lower than the bottom of the tab 122, the limiting of the tab 122 is cancelled, the safety belt insert 12 can be smoothly taken out, and after being taken out, the movable piece 112 moves upward as a whole under the action of the spring 113, and the sensor contact piece 1125 on the movable piece 112 is in a contact state with the receiving end of the safety belt explosion-proof sensor 2 inside the shell 111.

[0030] As shown in Figure 7 , the safety belt assembly 1 further comprises a support frame 14, the support frame 14 is hingedly connected to the end of the safety belt clamping piece 11 away from the safety belt insert 12, and the torque sensor 8 is arranged at the hinged shaft of the support frame 14 and the safety belt clamping piece 11. When the vehicle body is installed, the new support frame 14 is arranged at the side of the seat, the height of the support frame 14 is relatively high, and it is ensured that the safety belt clamping piece 11 can be smoothly rotated relative to the support frame 14 and is not disturbed by the surrounding environment.

[0031] When the driver unfastens the safety belt or does not fasten the safety belt, the safety belt assembly 1 is in a state that the tab 122 of the safety belt insert 12 is not inserted into the safety belt clamping piece 11, and the receiving end of the safety belt explosion-proof sensor 2 is in a contact state. In this state, the logic judgment module 3 receives the change of the safety belt explosion-proof sensor 2, so that the parking module 4 is enabled to work, the hand brake execution mechanism 5 makes the pressing piece press against the brake disc 7 to park, and the effect that the driver unfastens the safety belt to automatically park is realized.

[0032] In real life, some drivers do not wear seat belts during driving for the sake of convenience, and the seat belts remain in the state of being buckled up after the drivers get off the vehicle. In this case, it is impossible to determine whether the vehicle is parked or not by whether the seat belts are buckled up or not. To avoid this situation, the torque sensor 8 is additionally provided to determine whether the vehicle is parked or not when the seat belts are still in the state of being buckled up. The angle between the support frame 14 and the seat belt clamping piece 11 is different when the seat belts are buckled up or not. Thus, there are two cases, one is the angle range when the seat belts are not buckled up on the driver, and the other is the angle range when the seat belts are buckled up on the driver. The logic determination module 3 receives the angle change signal output by the torque sensor 8 under the premise that the receiving end of the seat belt anti-explosion sensor 2 is in the non-contact state, and determines that: when the angle is in the angle range when the seat belts are not buckled up on the driver, the parking execution module 4 is enabled, and the hand brake execution mechanism 5 makes the pressing piece press against the brake disc 7 to park the vehicle; when the angle is in the angle range when the seat belts are buckled up on the driver, the parking execution module 4 is not enabled, and the vehicle does not need to be parked. Thus, for the drivers who forget to pull the hand brake or tighten the hand brake during driving, whether the drivers get off the vehicle with the seat belts buckled up or not, the vehicle can be prevented from running away, and the personnel casualty and property loss caused by the vehicle running away can be avoided, so that the safety of the production site is improved. Moreover, the behavior of the drivers who do not buckle up the seat belts or buckle up the seat belts incorrectly can be reduced, and the illegal operation of the drivers who drive the vehicle without buckling up the seat belts can be effectively avoided.

[0033] The above is only an embodiment of the present application, and the well-known specific structures and properties in the scheme are not described in detail. It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims.
