DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] Welfare vehicles mainly refer to vehicles that can be directly and conveniently mounted on and off by wheelchairs of people with limited mobility. In my country, some companies call them "welfare vehicles" or "barrier-free vehicles". The present invention provides a welfare vehicle mounting device, such as Figure 1As shown, the device comprises a fixing base 1 for securing to the carriage floor. Said fixing base 1 is provided with a set of mutually symmetrical swing arm support bases 1-1 for connecting to a swing arm mechanism 3. The end of said swing arm mechanism 3 is connected to a walking board mechanism 2 for carrying a wheelchair. Said walking board mechanism 2 is driven by a translation drive mechanism 4 for horizontal telescopic movement and by the swing arm mechanism 3 for non-vertical lifting movement. The swing arm mechanism 3 and the translation drive mechanism 4 are controlled by a central control system 6. Specifically, a number of fixing devices for securing people and wheelchairs loaded into the carriage can be provided, depending on the space and passenger capacity.

[0030] As an optimization of this embodiment, Figure 4 As shown, the fixed seat 1 is composed of a group of mutually symmetrical horizontal plates 1-2 and a group of mutually symmetrical vertical plates 1-3 to form a rectangular frame, and mutually symmetrical limit bars 1-4 for limiting the walking of the walking plate mechanism 2 are respectively provided along the horizontal plates 1-2. This structure can ensure that the walking plate mechanism 2 maintains horizontal linear motion; the swing arm support seat 1-1 is provided on the horizontal plate 1-2 corresponding to the same end of the limit bar 1-4, and is located at the port of the horizontal plate 1-2 close to the compartment cover plate, so as to facilitate the moving of the walking plate mechanism 2 out of or into the compartment; a group of clamping blocks 1-5 for clamping the walking plate mechanism 2 are respectively provided at the other end of the limit bar 1-4, and the clamping blocks 1-5 are buckled with the block 2-23 provided on the walking plate mechanism 2, as shown Figure 3 As shown, the block 2-23 is used to prevent the walking plate mechanism 2 from completely sliding out of the swing arm mechanism 3, which can effectively reduce safety hazards. First connecting blocks 1-6 are respectively arranged near the clamping blocks 1-5, and first ramp plates 1-7 are movably connected between adjacent first connecting blocks 1-6. The first ramp plates 1-7 are used to smoothly and safely move people and wheelchairs in the car out of the device, so that they can be better fixed in the car.

[0031] To optimize safety, a locking device 1-8 is installed on the vertical board 1-3 adjacent to the first ramp 1-7. The locking device 1-8 mates with the pull ring at the end of the running board mechanism 2. This mechanism ensures that the running board mechanism 2 remains securely in the vehicle. Furthermore, the locking device 1-8 is connected to the central control system 6 for intelligent control. If the automated control fails, manual locking can be achieved, providing a double guarantee.

[0032] like Figure 4As shown, the walking board mechanism 2 includes a walking board 2-1 for carrying a wheelchair, and a sliding mechanism 2-2 is respectively provided on a group of sliding edges of the walking board 2-1. The sliding mechanism 2-2 is driven by a translation drive mechanism 4 to perform horizontal telescopic movement, including a rack track 2-21 and a pulley track groove 2-22 arranged parallel to each other up and down. The outward side of the walking board 2-1 is provided with a second ramp plate 2-4 movably connected by a second connecting block 2-3. The second ramp plate 2-4 is used for the smooth entry or exit of the wheelchair.

[0033] In this embodiment, a handrail 8 is also provided on any of the sliding mechanisms 2-2. When the person is on the walking board mechanism 2, the person can hold the handrail 8, which further enhances the safety of loading and reduces the psychological burden on the elderly during the operation of the device.

[0034] like Figure 1 and 2 As shown, a wheelchair locking mechanism 5 is located in the center of the walking board 2-1. The wheelchair locking mechanism 5 comprises four hooks for securing a wheelchair. The ends of the hooks are connected to steel cables, which are each connected to a locking handle via a monorail pulley. Pulling the locking handle tightens the hooks, thereby securing the wheelchair wheels. This device can secure various wheelchair models on the market, making it more convenient and adaptable.

[0035] like Figure 2 and 3 As shown, the translation drive mechanism 4 includes a set of mutually symmetrical limit baffles 4-1, between which a support plate 4-2 for supporting the walking plate mechanism 2 is connected; a motor 4-3 can be set on any of the limit baffles 4-1, and a gear 4-4 that matches the rack track 2-21 is connected to the rotating shaft of the motor 4-3. A set of horizontal transmission pulleys 4-6 are also set on the corresponding limit baffle 4-1 below the gear 4-4, and the transmission pulleys 4-6 match the pulley track groove 2-22. When the motor 4-3 receives a start command from the central control system 6, the motor 4-3 moves clockwise or counterclockwise according to the received command, and the rack track 2-21 is driven forward or backward by the rotation of the gear 4-4. At the same time, the transmission pulley 4-6 will drive the rotation during the forward or backward movement of the pulley track groove 2-22, playing a stabilizing role, so that the walking plate 2-1 can move forward and backward smoothly.

[0036] As an optimization of the translation drive mechanism 4, a clutch 4-5 is further provided between the motor 4-3 and the rack rail 2-21. The clutch 4-5 is manually controlled by a pin 4-7 provided on the top. This arrangement can solve the problem of the motor failing by manually controlling the clutch 4-5 via the pin 4-7 to achieve the purpose of separating the gear 4-4 from the rack rail 2-21. Then, by manually pushing, the walking plate mechanism 2 can be manually translated horizontally, which is particularly practical in emergency situations.

[0037] like Figure 5-7 As shown, the swing arm mechanism 3 includes a first arm 3-1, a second arm 3-2, a 7-shaped third arm 3-3 and a hydraulic cylinder 3-4, which are respectively movably clamped by the swing arm support seat 1-1. The bottom of the hydraulic cylinder 3-4 and the bottom of the second arm 3-2 are hinged to the swing arm support seat 1-1 at the same time. The top of the piston of the hydraulic cylinder 3-4 and the top of the first arm 3-1 are hinged to the top of the third arm 3-3 at the same time. The top of the second arm 3-2 is hinged to the top of the third arm 3-3. The first arm 3-1 and the second arm 3-2 always remain relatively parallel; the bottom end of the third arm 3-3 is fixed to the outside of the limit baffle 4-1.

[0038] In this device, the hydraulic cylinders 3-4 are supplied with pressure by a hydraulic pump system 7. This system can be controlled automatically by the central control system 6 or manually for emergency response. The central control system 6 in this system can be a human-machine interactive touch screen or a button-controlled mode. Furthermore, the power source for this device is provided by the vehicle.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
