[0032] The two lifting mechanisms 3 are constructed by combining two parallelogram mechanisms, and the lifting action is completed in a parallelogram deployment manner;
[0033] The base 31 in the lifting mechanism 3 is L-shaped and two long swing arms 32 are rotatably mounted at the end thereof, and the two long swing arms 32 are arranged in parallel; a connecting plate 34 is assembled and arranged at the other ends of the two long swing arms 32, and a parallelogram structure is formed between the connecting plate 34, the base 31, and the two long swing arms 32; both ends of the connecting plate 34 are rotatably provided with a twisting shaft 36, and a short connecting rod 35 is rotatably provided through the twisting shaft 36, and long connecting rod arms 37 are rotatably provided at both ends of the short connecting rod 35;
[0034] A wheelchair platform 310 is commonly assembled at the bottom of the two lifting mechanisms 3 .
[0035] In this embodiment, the transport vehicle of the present application is equipped with a lifting mechanism 3 inside the vehicle carrier 1, so that the user can be safely and reliably automatically moved into the vehicle through the lifting mechanism 3, avoiding manual labor and the problem of unusability caused by the narrow adaptability of the prior art; at the same time, the automatic control of the lifting mechanism 3 by the control device and the display panel ensures the safety of the lifting mechanism 3 during operation.
[0036] Furthermore, in actual use, the transport vehicle of the present application can transport two passengers at a time by means of two wheelchair positions arranged on the lifting mechanism 3, thereby improving the vehicle operation efficiency, saving time and energy. At the same time, the lifting action is completed by means of a combination of two sets of parallelogram structures, so that it occupies a small space when it is retracted into the vehicle carrier 1 during the folding movement, and its position is reasonable when it is extended out of the vehicle, and interference is avoided. The structure is reliable and the service life is long.
[0037] Furthermore, in actual use, the lifting mechanism 3 is hydraulically driven, so that the lifting mechanism 3 as a whole can withstand a large load, has a long service life, is easy to maintain, has high reliability and is easy to control.
[0038] It should be further noted that, considering the actual design and design cost issues, in this application, as in the embodiment Figure 5 As shown in , the telescopic part it refers to can be a guide rod cylinder part or a guide rod oil cylinder part. At the same time, in a preferred embodiment, in order to improve the accuracy during telescoping, the telescopic part of the present application can also be an electric driving structure, such as a driving structure part such as a guide rod motor. The control method or power connection method of the telescopic part shown are both prior arts, and the control circuit can be realized through simple programming by technicians in this field. It belongs to the common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.
[0039] It should be noted that the vehicle for transporting passengers with limited mobility in the present application is modified based on a road vehicle that can be used for an apron. The lifting mechanism 3 is used to assist passengers in entering and exiting the car from the rear door. Multiple measures such as logic control and sensor detection systems are adopted to ensure the high reliability and safety of the lifting mechanism 3. The overall system occupies as small an area as possible, increasing the internal space of the vehicle and reducing the impact on other personnel. It adopts a fully automatic hydraulic drive and is equipped with a manual emergency system that has less impact on comfort. A handheld switch is used, which can be operated inside or outside the car.
[0040] Specifically, refer to Figure 4 A plurality of fixed backrest seats 4 are arranged at intervals in the passenger area of the vehicle carrier 1. A wheelchair fixing area 5 for fixing a wheelchair is also formed in the vehicle carrier 1, and a wheelchair fixing part is arranged in the wheelchair fixing area 5.
[0041] In this embodiment, in actual deployment, when a passenger with limited mobility is transported to the vehicle carrier 1 via the lifting mechanism 3, the wheelchair fixing area 5 provided at this time can be used to fix the passenger's wheelchair. The wheelchair fixing parts provided in the wheelchair fixing area 5 can ensure that the wheelchair remains stable during the driving of the vehicle, and reduce the movement or tilting caused by acceleration, deceleration or turning of the vehicle, thereby protecting the safety of the wheelchair user. The provided wheelchair fixing parts are existing mature components and can be directly purchased and assembled by manufacturers.
[0042] Specifically, refer to Figure 5 A first telescopic member 33 is also obliquely mounted on the side of the base 31 , and an output end of the first telescopic member 33 is hinged to one end of one of the long swing arms 32 located above.
[0043] In this embodiment, in actual use, when the user connects the first telescopic member 33 to an external hydraulic pump, the output end of the first telescopic member 33 can be axially moved, and it moves axially or extends axially during use; at this time, the user controls the output end of the first telescopic member 33 to extend outward, and cooperates with the hinge of the end of the first telescopic member 33 to one of the long swing arms 32, so that the two long swing arms 32 can cooperate with the base 31 and the connecting plate 34 to extend in a parallelogram state, and then push the connecting plate 34 together with a number of short connecting rods 35 outward until the wheelchair platform 310 is pushed out. At this time, the wheelchair platform 310 can move in the vehicle carrier 1 until it moves to the outside of the vehicle carrier 1.
[0044] In a preferred embodiment, the output end of the first telescopic member 33 is hinged at the same position with the long swing arm 32 and the connecting plate 34 located above it, and the cylinder tail of the first telescopic member is hinged at the same position with the long swing arm and the base 31.
[0045] Specifically, refer to Figure 5 The upper end surface of the wheelchair platform 310 is provided with four articulated shaft seats 38 in a rectangular distribution, wherein two adjacent articulated shaft seats 38 are arranged as a group and are rotatably connected to the ends of two adjacent long connecting rod arms 37 respectively; the upper end surface of the wheelchair platform 310 is also provided with a guardrail 311.
[0046] In this embodiment, through the rotational connection between the articulated shaft seat 38 and the long connecting rod arm 37, the two long connecting rod arms 37 can be tilted in a parallel state, thereby realizing the horizontal placement of the wheelchair platform 310. In a preferred embodiment, the guardrail 311 can provide lateral protection for the wheelchair of the passenger with limited mobility. At the same time, the wheelchair placement area on the wheelchair platform 310 is a double wheelchair space setting in the preferred design. Under the premise that the wheelchair platform 310 can be fully inserted into the vehicle carrier 1, two passengers can be transported at a time by setting two wheelchair spaces, thereby improving the vehicle operation efficiency, saving time and saving energy.
[0047] Specifically, refer to Figure 5 Two matching rods 371 are rotatably provided on the two long connecting rod arms 37, and a parallelogram structure is formed between the two long connecting rod arms 37 and the two matching rods 371. A second telescopic member 39 is assembled on the side of the connecting plate 34, and the output end of the second telescopic member 39 is connected to one of the matching rods 371. An angle plate 351 is also rotatably provided between the short connecting rod 35 and the connecting plate 34.
[0048] In this embodiment, in actual use, when the wheelchair platform 310 is outside the vehicle carrier 1 and is used for passengers with limited mobility, the user can retract the wheelchair platform 310 by controlling the user. At this time, the output end of the second telescopic member 39 is retracted, and through the rotational connection between the long connecting rod arm 37 and the matching rod 371, and the rotational connection between the long connecting rod arm 37 and the articulated shaft seat 38, the second telescopic member 39 can drive the two long connecting rod arms 37, the matching rod 371 and the short connecting rod 35 to swing to the upper right as a whole, and gradually shrink in a parallelogram state; similarly, when the wheelchair platform 310 needs to be placed, the user controls the second telescopic member 39 to extend outward, and the second telescopic member 39 can drive the two long connecting rod arms 37, the matching rod 371 and the short connecting rod 35 to swing to the lower left as a whole, and gradually expand the spacing in a parallelogram state until the wheelchair platform 310 is horizontally transferred to the ground for placement.
[0049] Specifically, refer to Figure 1-4 The vehicle carrier 1 includes a cab 2 arranged at the front of the vehicle, and a control system for controlling the start and stop of a lifting mechanism 3 is integrated in the cab 2.
[0050] In this embodiment, in actual use, the control system arranged in the cab 2 can be used to control the start and stop of the lifting mechanism 3. The preferably arranged control system can also be integrated with an electrically connected display panel. The electrical connection between the display panel and the lifting mechanism 3, the control system, and the air circuit control of the lifting mechanism 3 are all mature technical means, which can be realized by simple programming by technicians in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and air circuit connection are not described in detail.
[0051] It should be noted that the lifting mechanism 3 is installed in the vehicle carrier 1 through the base 31. When the lifting mechanism 3 is not retracted into place, the control system locks the vehicle and cannot drive, and the display panel displays the current status. When the lifting mechanism 3 is retracted into place, the control system unlocks the vehicle and the display panel displays the current status. In a preferred design, the display panels are respectively arranged at the rear end of the vehicle body of the vehicle carrier 1 and in the cab 2, and the control device is arranged in the vehicle carrier 1; when the rear door of the vehicle is closed, the lifting mechanism 3 cannot move.
[0052] Furthermore, the overall operation steps of the lifting mechanism 3 are provided in a preferred embodiment, as follows: Figures 1 to 3 As shown in;
[0053] 1. Vehicle carrier 1 stops as a carrier;
[0054] 2. The control personnel controls the vehicle carrier 1 to open the rear door;
[0055] 3. The lifting mechanism 3 is controlled and extended, and the vehicle carrier 1 is locked;
[0056] 4. The passenger with limited mobility boards the wheelchair platform 310 and is safely carried;
[0057] 5. Control the lifting mechanism 3 to retract the wheelchair platform 310 until it is moved into the vehicle carrier 1;
[0058] 6. If there are other passengers, the first passenger moves to another wheelchair fixed position in the carriage and repeats steps 3-5;
[0059] 7. Close the rear door of vehicle carrier 1 and secure everyone;
[0060] 8. The vehicle carrier 1 is in motion to provide boarding for passengers with limited mobility.
[0061] The utility model of the lifting and transporting vehicle for passengers with limited mobility:
[0062] Step 1: The wheelchair platform 310 is initially on the ground, and the output end of the second telescopic member 39 is extended. When the wheelchair platform 310 is in place, the output end of the first telescopic member 33 on the side of the base 31 is extended, and then the two long swing arms 32 are extended to one side in a parallelogram state in cooperation with the base 31 and the connecting plate 34. During this period, the two long connecting rod arms 37 can cooperate with the short connecting rod 35 and the matching rod 371 to swing downward in a parallelogram state, and at the same time, the wheelchair platform 310 is moved to the lower left as a whole. At this time, the user can board the wheelchair platform 310 to complete the ride;
[0063] Step 2: The user presses the recovery button on the control panel, at which time the output end of the second telescopic member 39 contracts, driving the two long connecting rod arms 37, the matching rod 371 and the short connecting rod 35 to swing to the upper right as a whole, and gradually shrink in a parallelogram state until it is in a limited position; then the output end of the first telescopic member 33 contracts, causing the connecting plate 34 to move to the right as a whole, until the wheelchair platform 310 is received into the vehicle carrier 1; then the action stops, completing the loading of the wheelchair platform 310 and the passenger.
[0064] Step 3: The steps of setting the wheelchair platform 310 out of the vehicle are opposite to the above steps.
[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
