Description

Technical Field

[0001] The invention relates to the technical field of safety seats, and in particular to a vehicle-getting-on and -off assisting device for elderly persons with an automatic adjustment function. Background Art

[0002] With the continuous development of automobile manufacturing technology, in addition to the continuous improvement of vehicle safety, the design of riding comfort for drivers and passengers is also constantly improving. Compared with ordinary sedans or SUV models, MPV models have larger space, the side doors adopt a pull-out door design, the rear door space and aisle area are larger, and the seats are more comfortable. If there are elderly people in the family who have difficulty in moving and need to be sent to the hospital at any time, or some social service vehicles, the seats of MPV vehicles can provide higher comfort, and the large area can also provide more space for getting off.

[0003] Although MPV vehicles have comfortable seats and large space, the aisle area inside the vehicle basically only allows one operator to stand. If the elderly person is sitting on the seat, only a single operator can pick them up and get them out of the vehicle. This process is very strenuous. Due to limited space, caregivers or other operators outside the vehicle cannot provide assistance. Both the operator and the elderly are at risk of hitting their heads against the door frame. If the elderly person is heavy, the operator cannot lift him up in one go, which increases the risk of the elderly person being injured again. Summary of the invention

[0004] The purpose of the present application is to provide a vehicle getting on and off assisting device for the elderly with an automatic adjustment function, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, this application provides the following technical solutions: A vehicle-mounting assistance device for the elderly with an automatic adjustment function comprises a backboard and a movable plate, wherein: an engaging block is fixedly mounted on an outer wall of one side of the backboard, a movable groove is formed through the outer wall of the movable plate, the movable plate is fitted with the outer wall of the backboard, the engaging block is engaged in the movable groove, a gripping mechanism is arranged above one side of the backboard, a cushion mechanism is arranged on the outer wall of one side of the movable plate, the gripping mechanism comprises a handle, an engaging rod and a rotating assembly, the cushion mechanism comprises a cushion plate and a supporting assembly, the rotating assembly comprises a sleeve and a pull rod, and the outer wall of the sleeve is fitted with the outer wall of the backboard. The wall is installed on the back plate through a bearing, the embedded rod is embedded in the sleeve, the pull rod 2 is fixedly installed on the outer wall of the sleeve, the support assembly includes a support plate and a pull rod 1, the support plate is fixedly installed on the side of the movable plate away from the back plate and is arranged parallel to the movable plate, the cushion plate is movably installed on one side of the support plate, the pull rod 1 is fixedly installed on the top of one end of the support plate, a guide plate is arranged between the pull rod 1 and the pull rod 2, the guide plate is fixedly installed on the back plate, the pull rod 1 is connected to the pull rod 2 by a wide rubber band, and the wide rubber band passes through the lower outer wall of the guide plate.

[0006] After the seat cushion is flipped, its plane height is close to that of the car seat. After the seat cushion is opened, the operator can place the elderly's legs on the seat cushion if they cannot move and need emergency medical treatment. The legs will not occupy the aisle area of ​​the vehicle, and the elderly will be in a semi-lying state. At this time, the operator inside the car only needs to lift the elderly's upper body, and the operator outside the car will lift the elderly's legs. The two operators inside and outside the car will quickly lift the elderly to a stretcher or wheelchair. This means that the operator does not need to carry the elderly out of the car while they are in a sitting position. They can cooperate with other operators to quickly get the elderly out of the car, reducing the burden on the operators.

[0007] The beneficial effect of the present invention is that by providing a cushion plate and a support assembly, an operator can place the elderly's legs on the cushion plate, and the elderly is in a semi-lying state. At this time, the operator inside the vehicle only needs to lift the elderly's upper body, and the operator outside the vehicle lifts the elderly's legs, and the two operators inside and outside the vehicle quickly lift the elderly to a stretcher or wheelchair. The operator does not need to carry the elderly out of the vehicle when the elderly is in a sitting position, and can cooperate with other operators to quickly send the elderly out of the vehicle.

DETAILED DESCRIPTION

[0010] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more explicit definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only referenced to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0011] like Figure 1-13 The vehicle-mounting assist device for the elderly with an automatic adjustment function shown in the figure comprises a backboard 1 and a movable board 3, a fitting block 28 is fixedly mounted on the outer wall of one side of the backboard 1, a movable groove 27 is formed through the outer wall of the movable board 3, the movable board 3 is fitted with the outer wall of the backboard 1, the fitting block 28 is fitted inside the movable groove 27, a gripping mechanism is arranged on the upper side of one side of the backboard 1, a cushion mechanism is arranged on the outer wall of one side of the movable board 3, the gripping mechanism comprises a handle 2, a fitting rod 8 and a rotating assembly, the cushion mechanism comprises a cushion board 4 and a supporting assembly, the rotating assembly comprises a sleeve 16 and a pull rod 17, the outer wall of the sleeve 16 is mounted by a bearing On the back plate 1, the engaging rod 8 is embedded and installed inside the sleeve 16, and the pull rod 17 is fixedly installed on the outer wall of the sleeve 16. The support assembly includes a support plate 6 and a pull rod 15. The support plate 6 is fixedly installed on the side of the movable plate 3 away from the back plate 1 and is arranged parallel to the movable plate 3. The cushion plate 4 is movably installed on one side of the support plate 6. The pull rod 15 is fixedly installed on the top of one end of the support plate 6. A guide plate 11 is arranged between the pull rod 15 and the pull rod 2 17. The guide plate 11 is fixedly installed on the back plate 1. The pull rod 15 is connected to the pull rod 2 17 by a wide rubber band, and the wide rubber band passes through the lower outer wall of the guide plate 11.

[0012] See also Figure 1 , 5 13. The back panel 1 is fixedly mounted on the supporting shell on the side of the seat. The supporting shell is a matching part of the seat. The supporting shell is detachable. When installing the integral auxiliary device, the supporting shell can be disassembled. After the back panel 1 and the supporting shell are fixed with bolts, the auxiliary device together with the supporting shell can be installed on the side of the seat again. The handle 2 consists of a long metal rod and a grip rod. The grip rod is vertically fixed at one end of the long metal rod, and the other end of the long metal rod is fixed on the engaging rod 8.

[0013] See also Figure 7In the initial state, the long metal rod of the handle 2 is parallel to the upper edge of the movable plate 3, which plays a protective role after the elderly sit down, and the cushion plate 4 is in a retracted state. The interlocking rod 8 can be rotated on the back plate 1 through the sleeve 16, and the movable plate 3 can be moved on the back plate 1. When the cushion plate 4 needs to be opened, the operator pulls the movable plate 3, and the movable groove 27 moves on the interlocking block 28. The interlocking block 28 provides guidance for the movable plate 3 and stabilizes the moving direction. Pulling the movable plate 3 outward can drive the support plate 6, the cushion plate 4 and the support assembly to move together, so that the cushion plate 4 completely leaves the area between the door and the seat, and the cushion plate 4 is flipped through the support assembly and supported after flipping.

[0014] After the seat cushion 4 is turned over, the plane height is close to the height of the car seat. After the seat cushion 4 is opened, the operator can place the legs of the elderly who cannot move and need to be sent to the doctor urgently on the seat cushion 4, and the legs will not occupy the aisle area of ​​the get-off place, and the elderly are in a semi-lying state. At this time, the operator in the car only needs to lift the upper body of the elderly, and the operator outside the car will lift the legs of the elderly, and the two operators inside and outside the car will quickly lift them to a stretcher or wheelchair. This makes it unnecessary for the operator to carry the elderly to get off the car when the elderly are in a sitting position, and can cooperate with other operators to quickly send the elderly off the car, reducing the burden on the operators.

[0015] See also Figure 2 , 8 When the movable plate 3 is pulled, the wide rubber band between the pull rod 15 and the pull rod 2 17 is pulled, the pull rod 15 on the support plate 6 pulls the pull rod 2 17, the pull rod 2 17 drives the sleeve 16 to flip, the sleeve 16 drives the embedded rod 8, the embedded rod 8 drives the handle 2 to flip, and the handle 2 leaves the upper area of ​​the seat cushion 4 after flipping, so that when the operator needs the seat cushion 4 to assist the elderly to get off the car, the movable plate 3 is pulled, and the handle 2 will automatically flip over. After the movable plate 3 is recovered to the initial position, the operator can flip the handle 2 downward to reset it to serve as an armrest.

[0016] A side panel 26 is fixedly installed on the edge of one side of the mounting handle 2 of the back panel 1, a magnetic plate 9 is fixedly installed on the end of the support plate 6 facing the side panel 26, the magnetic plate 9 is installed between the support plate 6 and the movable plate 3, the side panel 26 is made of ferrous metal, the side panel 26 is adsorbed on the magnetic plate 9, a telescopic rod 7 is fixedly installed on the side of the side panel 26 facing the magnetic plate 9, the telescopic rod 7 is composed of a fixed tube and a movable rod, the fixed tube is sleeved on the outside of the movable rod, the fixed tube of the telescopic rod 7 passes through the magnetic plate 9, the movable rod end of the telescopic rod 7 is fixedly connected to the end of the movable plate 3 away from the side panel 26, and a support block 10 is fixedly installed on the top of the side panel 26.

[0017] See also Figure 4-6In the initial state, one end of the movable plate 3 and the support plate 6 is in contact with the side plate 26, and the magnetic plate 9 is adsorbed with the side plate 26. The function of the support block 10 is that after the handle 2 is flipped, the outer wall of the interlocking rod 8 contacts the top outer wall of the support block 10, and the support block 10 plays the role of supporting the interlocking rod 8. After pulling the movable plate 3, the length of the telescopic rod 7 increases. By design, the length that the movable rod of the telescopic rod 7 can be extended is the maximum distance that the movable plate 3 can move. The telescopic rod 7 can limit the moving distance of the movable plate 3. The cooperation of the movable groove 27 and the interlocking block 28 plus the telescopic rod 7 simultaneously controls the moving direction of the movable plate 3, so that the movement of the movable plate 3 will not be offset.

[0018] The rotating assembly also includes an annular shell 18, which is arranged below the sleeve 16 and movably mounted on the back plate 1. A center tube 25 is rotatably mounted at the center of the annular shell 18. The outer wall of the center tube 25 is connected to the outer wall of the annular shell 18 through a bearing. A cross groove is provided on the bottom outer wall of the center tube 25. A cross block is fixedly mounted on the bottom outer wall of the engaging rod 8. The cross block at the bottom end of the engaging rod 8 is embedded in the cross groove of the center tube 25. A slot plate 19 is fixedly mounted on the outer wall of the back plate 1. An arc-shaped slot is provided on the outer wall of the slot plate 19. A locking plate 24 is embedded in the arc-shaped slot of the slot plate 19. The locking plate 24 is fixedly connected to the outer wall of the annular shell 18.

[0019] See also Figure 2-3 When the engaging rod 8 is driven to rotate by the sleeve 16, the bottom of the engaging rod 8 will drive the central tube 25, and the central tube 25 will drive the annular shell 18 to flip synchronously. To ensure that the handle 2 is driven by the engaging rod 8 to flip to the specified position, the arc-shaped notch on the groove plate 19 is a quarter arc. When the sleeve 16 is pulled and flipped, the annular shell 18 drives the engaging plate 24 to slide to the other end in the groove plate 19, and the handle 2 is driven by the engaging rod 8 to flip ninety degrees.

[0020] See also Figure 2-3 A rotating block 20 is fixedly installed on the outer wall of the central tube 25, and the rotating block 20 is installed inside the annular shell 18. A guide block 21 is fixedly installed inside the annular shell 18. A through groove is opened on the outer wall of the guide block 21. A guide rod 22 and a spring 23 are arranged between the rotating block 20 and the guide block 21. The guide rod 22 is in the shape of an arc-shaped bent rod. One end of the guide rod 22 is fixedly connected to the rotating block 20, and the other end passes through the through groove of the guide block 21. The spring 23 is sleeved on the outside of the guide rod 22.

[0021] Under the premise that the elderly can get on the bus by themselves, after the door is opened, the elderly can hold the handle 2, and the elderly can pull themselves with the help of the handle 2, and cooperate with the leg to get on the bus, and the handle 2 provides a support point for the elderly. When the elderly exert force, the force will drive the handle 2, and the handle 2 will achieve a certain angle of flipping outside the door, and the handle 2 will drive the interlocking rod 8, and the cross block at the bottom of the interlocking rod 8 will cooperate with the cross groove at the bottom of the center tube 25, and the interlocking rod 8 will drive the center tube 25 to rotate, and the center tube 25 will drive the rotating block 20 to rotate inside the annular shell 18, and the guide rod 22 will slide in the through groove of the guide block 21, and the spring 1 23 will be compressed and deformed, and the spring 1 23 will provide resistance to buffer the pulling force of the elderly. When the elderly pull the handle 2, the handle 2 will flip a certain angle and use the spring 1 23 to buffer part of the pulling force. Compared with the ordinary handrails on the vehicle that can only be turned up and down, when the elderly use the handrails as support to pull themselves, if the hand slips or the handrails are not buffered and are pulled off, the elderly will fall directly backwards, causing very serious consequences.

[0022] The support assembly also includes two triangular support frames, which are installed between the seat cushion plate 4 and the support plate 6. The triangular support frames are composed of a fitting rod 12, a rotating rod 13 and two connecting rods 14. The fitting rod 12 is in the shape of a U-shaped stainless steel bar. The outer wall of one end of the fitting rod 12 is fixedly installed on the support plate 6. One end of the rotating rod 13 is rotatably installed between the outer walls of both sides of the fitting rod 12. A sliding groove 34 is provided on the side of the rotating rod 13. The two connecting rods 14 are fitted on both sides of the fitting rod 12. One end of the two connecting rods 14 is rotatably installed on the outer wall of the fitting rod 12. A sliding rod 50 is fixedly installed between the other ends of the two connecting rods 14, and the sliding rod 50 is penetrated into the inside of the sliding groove 34. The rotating rod 13 is shaped like a U-shaped stainless steel bar, and the opening of the rotating rod 13 faces the supporting plate 6. A movable plate 47 is rotatably installed between the side walls of the rotating rod 13. The movable plate 47 is installed at one end of the slide groove 34 close to the fitting rod 12. A fixed shaft 48 is fixedly installed between the two side walls of the rotating rod 13. The fixed shaft 48 passes through the movable plate 47. The movable plate 47 is connected to the outer wall of the fixed shaft 48 by a torsion spring. The torsion spring is sleeved on the fixed shaft 48. One end of the torsion spring is fixed on the movable plate 47, and the other end is fixed on the fixed shaft 48. A slide rail 33 is fixedly installed on the outer wall of the rotating rod 13, and the seat cushion plate 4 is slidably installed on the slide rail 33. A mounting rod 5 is fixedly installed on the end of the slide rail 33, and a fixing rod 31 is fixedly installed on the outer wall of the mounting rod 5. A slideway is opened through the outer wall of the end of the seat cushion plate 4, and the seat cushion plate 4 is sleeved on the fixing rod 31 through the slideway. A magnetic block 42 is fixedly installed on the outer wall of the support plate 6, and an iron plate 46 is fixedly installed on the outer wall of the seat cushion plate 4 facing the support plate 6, and the iron plate 46 is adsorbed and fixed to the magnetic block 42.

[0023] See also Figure 7 , 9, 11-12, in the initial state, the rotating rod 13 and the movable plate 47 are located inside the fitting rod 12. When the cushion plate 4 is flipped, the iron plate 46 is separated from the magnetic block 42, and the cushion plate 4 drives the slide rail 33, and the slide rail 33 drives the rotating rod 13 to rotate at the top of the fitting rod 12. The sliding rod 50 at the end of the connecting rod 14 slides in the sliding groove 34, and the sliding rod 50 drives the connecting rod 14 to unfold. When the sliding rod 50 passes through the movable plate 47, the top of the movable plate 47 flips downward on the fixed shaft 48, and the torsion spring is twisted and deformed. After the sliding rod 50 passes through the movable plate 47, the movable plate 47 is driven to reset by the torsion spring, and the sliding rod 50 passes through the movable plate 47 and moves to the end of the sliding groove 34. The flipped and reset movable plate 47 resists the sliding rod 50, so that the sliding rod 50 cannot move, and the connecting rod 14 cannot move. At this time, the rotating rod 13 and the fitting rod 12 are in a vertical state and cannot move, and the cushion plate 4 is flipped upward by ninety degrees. This opening method is relatively convenient, and the operator only needs to exert force to separate the iron plate 46 from the magnetic block 42 to flip it over.

[0024] See also Fig.11 The flipped seat cushion 4 can not only support the elderly's legs when getting off the car, but also can be flipped when getting on the car. One operator or multiple operators can carry the elderly to the seat cushion 4. The elderly can sit on the seat cushion 4. The elderly with certain mobility in the upper limbs can move to the seat by themselves. Due to the limitation of the door space, only one operator can carry the elderly to the seat, and the space is obviously insufficient. In addition, the operator needs to bend down and get on the car when carrying the elderly. These actions require strength and are difficult to complete. Therefore, the elderly can sit on the seat cushion 4, and the elderly can move to the seat by themselves, or the operator can get on the car from the other side door and drag the elderly on the seat cushion 4 to the seat, which is a more labor-saving way. A slider is installed at the bottom of the seat cushion 4, and the slider is embedded in the slide rail 33. The seat cushion 4 can be pulled outward for a certain distance. The fixed rod 31 and the slide rail 33 both serve as movement guides for the seat cushion 4. The distance between the seat cushion 4 and the mounting rod 5 is increased. When the elderly are taller and need more space for leg extension, the seat cushion 4 can be pulled.

[0025] See also Fig.12 When the cushion plate 4 needs to be recovered, the operator lifts the bottom of the two movable plates 47 with both hands at the same time, so that the top of the movable plate 47 flips downward, and the slide bar 50 can move. At this time, the operator presses down the cushion plate 4 again, so that the rotating rod 13 flips downward, and the slide bar 50 slides in the slide groove 34 until the rotating rod 13 and the movable plate 47 are recovered to the inside of the fitting rod 12, and the iron plate 46 is adsorbed by the magnetic block 42.

[0026] A matching block 29 is fixedly installed on the outer wall of the mounting rod 5 on one side away from the cushion plate 4, and arc-shaped grooves are symmetrically provided on the outer walls on both sides of the matching block 29. Spring tubes 30 are installed in pairs on the upper outer wall of the movable plate 3. The pairs of spring tubes 30 are symmetrically arranged, and a spring 2 35 is installed inside the spring tubes 30. A chimeric ball 36 is embedded and installed at the end of the spring tube 30. The chimeric ball 36 is fixedly connected to the spring 2 35. The area between the pairs of spring tubes 30 corresponds to the position of the matching block 29, and the shape of the outer wall of the chimeric ball 36 is adapted to the groove of the matching block 29.

[0027] See also Fig.10 , the mounting rod 5 is driven by the cushion plate 4 to flip, and the matching block 29 will be engaged between the two spring tubes 30. When the matching block 29 is driven by the mounting rod 5 to flip, it first contacts the outer wall of the embedded ball 36 and pushes the embedded ball 36 into the spring tube 30. The spring 2 35 is compressed and deformed. As the matching block 29 moves, the grooves on both sides of the matching block 29 move to the end of the spring tube 30, and the embedded ball 36 obtains a movable space. The spring 2 35 quickly pushes the embedded ball 36 into the groove of the matching block 29. Both the matching block 29 and the embedded ball 36 are made of metal. After the collision, a crisp sound will be emitted, which means that the cushion plate 4 has flipped into place. The paired embedded balls 36 not only play the role of engaging the matching block 29, but also play a prompting role, prompting the operator that the cushion plate 4 has flipped into place. Since the surfaces of the groove and the embedded ball 36 are both arc surfaces and the embedded ball 36 is movable, when the cushion plate 4 flips down and resets, the matching block 29 and the embedded ball 36 can also be separated smoothly.

[0028] Two engaging grooves 38 are formed on the outer wall of the mounting rod 5 facing the seat cushion plate 4, and an intermediate rod 37 is fixedly installed inside the engaging groove 38. Clamping blocks 39 are fitted on both sides of the intermediate rod 37. The two clamping blocks 39 are symmetrically arranged on both sides of the intermediate rod 37. One end of the clamping block 39 is rotatably mounted on the end of the seat cushion plate 4. A hole is formed at the end of the clamping block 39. A rod body is fixedly installed on the end of the seat cushion plate 4. The clamping block 39 is sleeved on the rod body through the circular hole. The two clamping blocks 39 are connected by a spring three 40, and the end of the spring three 40 is fixedly mounted on the clamping block 39.

[0029] See also Fig.10The edges of the two clamping blocks 39 at the joint are provided with a semicircular notch, and the two semicircular notches form a circular notch, and the semicircular notches of the clamping blocks 39 are in contact with the outer wall of the middle rod 37. When the cushion plate 4 is pulled, the two clamping blocks 39 are subjected to tension, slide on the outer wall of the middle rod 37 and unfold inside the engaging groove 38, one end of the clamping block 39 rotates on the rod body of the cushion plate 4, and the spring three 40 is stretched and deformed. After the clamping block 39 is completely separated from the middle rod 37, the spring three 40 drives the two clamping blocks 39 to return to contact, and the cushion plate 4 is not restricted and can slide on the fixed rod 31. When the cushion plate 4 is retracted, the front ends of the two clamping blocks 39 are curved surfaces, and the two clamping blocks 39 contact the outer wall of the middle rod 37 and expand to both sides. The spring three 40 stretches and deforms until the semicircular notches on the edges of the two clamping blocks 39 fit with the outer wall of the middle rod 37. The two clamping blocks 39 clamp the middle rod 37, which can fix the cushion plate 4 and prevent the cushion plate 4 from sliding freely on the slide rail 33.

[0030] It should be noted that the parts not involved in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

[0031] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
