Description

Technical Field

[0001] This application relates to the technical field of welfare equipment, and in particular to a mobile device for welfare seating equipment. Background Technology

[0002] With the aging population and increasing attention to the travel rights of people with disabilities, the demand for mobility aids, particularly welfare seats which are crucial for assisting people with mobility impairments in transferring within vehicles and moving indoors, is growing. (Refer to...) Figure 1 The moving device of the welfare seat is used in conjunction with the drive structure 6. The lifting sliding plate 1 is set on the lifting mechanism 61 in the drive structure 6. This type of moving device needs to undertake functions such as position movement and stable fixation, which is directly related to the user's travel safety and operational autonomy. It is a core component for improving the practical value of the welfare seat.

[0003] Existing welfare seat moving devices mostly adopt a split design, some of which rely on manually pushed moving structures, or connect the seat and moving device through bolts or simple buckles; they generally have the problem of complicated operation procedures, such as height adjustment requiring manual locking in steps, seat disassembly and assembly requiring tools, and some devices are prone to shaking during movement.

[0004] Regarding the aforementioned technologies, the applicant believes that they suffer from insufficient ease of operation and difficulty in compatibility with multiple specifications. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a mobile device for welfare seating equipment.

[0006] This application provides a mobile device for welfare seating equipment, which adopts the following technical solution: A movable device for a welfare seating equipment includes a lifting sliding plate. The lifting sliding plate is provided with multiple locking mechanisms and a moving mechanism. The moving mechanism includes a moving plate, multiple moving components, and multiple rotating components. The bottom of the moving plate is provided with multiple positioning holes, and a drive lever is provided on one side of each of the positioning holes. The locking mechanisms cooperate with the positioning holes. The multiple rotating components are respectively rotatably disposed on both sides of the moving plate. The moving components are mounted on the rotating components and are used to drive the moving components to rotate. The moving plate is mounted on the lifting sliding plate via the locking mechanisms. A fixing mechanism is provided on the moving plate for connecting the welfare seating.

[0007] By adopting the above technical solution, the lifting sliding plate is equipped with multiple sets of locking mechanisms and moving mechanisms. The lifting sliding plate, in conjunction with the locking mechanisms and positioning holes, achieves precise positioning of the welfare seat. The tight cooperation between the locking mechanisms and positioning holes ensures the stability of the welfare seat. The rotating component in the moving mechanism drives the moving component to flip, allowing the welfare seat to move flexibly. The rotating component can drive the moving component to flip. When the welfare seat is moved outside the vehicle by the drive device, the locking mechanism unlocks the rotating component, driving the moving component to flip, thus propelling the welfare seat outside the vehicle. When the welfare seat is moved into the vehicle by the drive device, the rotating component retracts the moving component. The moving plate is set on the lifting sliding plate through the locking mechanism, and the bottom of the moving plate has positioning holes and a drive lever. The drive lever engages the locking mechanism with the positioning holes. The positioning holes and drive lever also help improve the accuracy and reliability of movement and positioning. The fixing mechanism on the moving plate is used to connect the welfare seat, making the installation and removal of the seat more convenient. The fixing mechanism can quickly and firmly connect the welfare seat to the moving device, facilitating the installation and replacement of various different seats, while also ensuring the safety and stability of the seat during use.

[0008] Preferably, the lifting sliding plate is provided with multiple sets of sliding grooves, and a reset groove is provided on the outer side of the sliding groove.

[0009] By adopting the above technical solution, multiple sets of sliding grooves provide independent and precise sliding tracks for the sliding rods of multiple sets of locking mechanisms, avoiding mutual interference when different components slide, ensuring that multiple sets of locking mechanisms can cooperate synchronously and smoothly with the positioning holes of the moving plate, improving the reliability of the overall locking and unlocking action, and the reset groove cooperates to complete the unlocking operation.

[0010] Preferably, the locking mechanism includes a drive rod, a sliding rod, a positioning rod, and a positioning component. The positioning component is disposed at one end of the sliding groove, the sliding rod is slidably disposed within the sliding groove, the drive rod is fixedly connected to the end of the sliding rod away from the positioning component, and the positioning rod is rotatably connected to the other end of the sliding rod.

[0011] By adopting the above technical solution, the positioning rod cooperates with the positioning hole on the moving plate, and the positioning component limits the sliding rod, forming multiple locking protections. This effectively prevents the moving plate from accidentally shifting or loosening when carrying the welfare seat, ensuring safety during the movement and switching process. The drive rod is directly fixedly connected to the sliding rod. When the moving component moves the moving plate towards the lifting sliding plate, the drive lever at the bottom of the moving plate moves the drive rod to drive the sliding rod to slide along the sliding groove, thereby controlling the positioning rod to push the positioning component to lock along the positioning hole. After rotating the drive rod, it slides back along the reset groove to unlock the positioning component.

[0012] Preferably, each of the multiple sets of locking mechanisms is provided with a reset rod on the drive rod, and the reset rod drives the sliding rod to rotate in the sliding groove through the drive rod.

[0013] By adopting the above technical solution, pulling the reset rod can simultaneously drive the drive rod to move, causing the reset rod to move in the reset groove, thereby driving multiple sets of sliding rods to move synchronously in the sliding groove, thus unlocking the locking mechanism.

[0014] Preferably, the positioning component includes a positioning plate, a return spring, and a positioning pin. The positioning plate is provided with a guide hole. One end of the positioning pin is provided with a top ring, and the other end of the positioning pin is provided with an inclined surface. The positioning pin is slidably connected in the guide hole. The return spring is sleeved on the positioning pin. In its natural state, one end of the return spring is fixedly connected to the top ring, and the other end of the return spring is fixedly connected to the positioning plate.

[0015] By adopting the above technical solution, when the drive lever pushes the drive rod, the positioning rod slides along the inclined surface of the positioning pin, which can automatically squeeze the positioning pin to move upward, so that the positioning pin is inserted into the moving plate. When the drive rod rotates to reset, the positioning rod moves away, and the return spring pulls the positioning pin to automatically reset. The return spring always applies elastic force to the positioning pin. Even if slight vibration occurs during the movement or loading of the welfare seat, it can also prevent the positioning pin from accidentally dislodging, ensuring the long-term stability of the locking mechanism and reducing safety risks. The inclined surface design of the positioning pin greatly reduces the frictional resistance when the positioning rod is pushed.

[0016] Preferably, the rotating assembly includes a support rod, a first connecting rod, a second connecting rod, and a drive push rod. One end of the support rod is rotatably connected to a movable plate, one end of the first connecting rod is rotatably connected to the movable plate, one end of the second connecting rod is rotatably connected to the other end of the first connecting rod, and the other end of the second connecting rod is rotatably connected to the middle of the support rod. The base end of the drive push rod is rotatably connected to the movable plate, and the working end of the drive push rod is rotatably connected to one side of the other end of the first connecting rod.

[0017] By adopting the above technical solution, when the first link and the second link are collinear and form a dead point through the push of the drive push rod, the support rod is perpendicular to the ground. At this time, the rotating component forms a stable triangular structure, which effectively distributes and bears the weight from the welfare seat and the user, providing reliable support and ensuring that the welfare seat will not easily shake or tip over during use, thus ensuring the safety of the user. The setting of the drive push rod makes the power transmission more direct and efficient. Through the extension and retraction of the drive push rod, the rotation of the first link and the second link can be easily pushed, thereby realizing the flipping of the support rod and the switching of the support state.

[0018] Preferably, the moving component includes a motor and a drive wheel. The base of the motor is fixedly connected to a support rod, and the drive wheel is rotatably connected to the other end of the support rod. The working end of the motor is connected to the drive wheel, and the motor provides power for the rotation of the drive wheel.

[0019] By adopting the above technical solution, the base of the motor is fixed on the support rod, and the working end is directly connected to the drive wheel, which reduces the intermediate links in the power transmission process, reduces energy loss, and can efficiently transmit the power generated by the motor to the drive wheel, thereby ensuring that the drive wheel obtains sufficient torque and speed to drive the equipment to move smoothly. The motor has good speed regulation performance, and the speed and direction of the drive wheel can be precisely adjusted by controlling the motor.

[0020] Preferably, the fixing mechanism includes a fixing sleeve, a sliding sleeve, a locking sleeve, multiple sets of top springs, multiple sets of fixing springs, and multiple sets of fixing pins. The bottom end of the fixing sleeve is fixedly connected to the moving plate. The top end of the fixing sleeve is provided with multiple sets of fixing holes. The multiple sets of fixing springs are respectively disposed in the fixing holes. The fixing pins are slidably disposed in the fixing holes. One end of the fixing spring is fixedly connected to one end of the fixing pin, and the other end of the fixing spring is fixedly connected to the bottom of the fixing hole. The other end of the fixing pin is an inclined surface. The sliding sleeve is slidably disposed in the fixing sleeve. One end of the multiple sets of top springs is fixedly connected to the bottom of the fixing sleeve, and the other end of the multiple sets of top springs is fixedly connected to the bottom of the sliding sleeve. The locking sleeve is provided with a locking hole and is disposed at the bottom of the welfare seat.

[0021] By adopting the above technical solution, during installation, the locking sleeve at the bottom of the welfare seat is aligned with the sliding sleeve in the fixing sleeve and pressed down. When the locking hole and the fixing hole are aligned, the fixing spring automatically pushes the fixing pin into the locking hole, completing the automatic locking. During disassembly, the welfare seat is lifted up, and the fixing pin is disengaged from the locking hole through the inclined surface, thus releasing the fixing pin. The sliding sleeve will also be pushed up by the top spring, causing the fixing pin to retract into the fixing hole, assisting the seat to disengage. No complicated tools are required throughout the process, making the operation efficient and labor-saving.

[0022] In summary, this application includes at least one of the following beneficial technical effects: By cooperating with the positioning rod and the positioning hole on the moving plate, and combined with the positioning component limiting the sliding rod, multiple locking protections can be formed to effectively prevent the moving plate from accidentally shifting or loosening when carrying the welfare seat, ensuring safety during the movement and switching process. The drive rod is directly fixedly connected to the sliding rod. When the moving component drives the moving plate to move towards the lifting sliding plate, the drive lever at the bottom of the moving plate moves the drive rod to drive the sliding rod to slide along the sliding groove, thereby controlling the positioning rod to push the positioning component to lock along the positioning hole. After rotating the drive rod, it slides back along the reset groove to unlock the positioning component.

[0023] When the first and second links collinearly form a dead point through the push of the drive push rod, the support rod is perpendicular to the ground. At this time, the rotating assembly forms a stable triangular structure, effectively distributing and bearing the weight from the welfare seat and the user, providing reliable support, and ensuring that the welfare seat will not easily shake or tip over during use, thus ensuring the safety of the user. The setting of the drive push rod makes the power transmission more direct and efficient. Through the extension and retraction of the drive push rod, the rotation of the first and second links can be easily pushed, thereby realizing the flipping of the support rod and the switching of the support state.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] Reference Figure 1 In the welfare seat installation device, the moving device of the welfare seat is used in conjunction with the drive structure 6, wherein the lifting sliding plate 1 is set on the lifting mechanism 61 in the drive structure 6.

[0032] This application discloses a mobile device for a welfare seating system. (See also...) Figure 2 and Figure 3 The system includes a lifting sliding plate 1, which is equipped with multiple locking mechanisms 2 and a moving mechanism 3. The moving mechanism 3 includes a moving plate 31, multiple moving components 32, and multiple rotating components 33. The bottom of the moving plate 31 is provided with multiple positioning holes 311, and a drive lever 312 is provided on one side of each of the multiple positioning holes 311. The moving plate 31 moves toward the lifting sliding plate 1 through the moving components 32, causing the drive lever 312 to drive the locking mechanism 2 to cooperate with the positioning hole 311. The multiple rotating components 33 are respectively rotatably arranged on both sides of the moving plate 31. The moving components 32 are arranged on the rotating components 33, and the rotating components 33 are used to drive the moving components 32 to flip. The moving plate 31 is set on the lifting sliding plate 1 through the locking mechanism 2. The moving plate 31 is provided with a fixing mechanism 4, which is used to connect the welfare seat.

[0033] Reference Figure 3 and Figure 4Multiple sliding grooves 11 are provided on the lifting sliding plate 1. A reset groove 12 is provided on the outer side of each sliding groove 11. The locking mechanism 2 includes a drive rod 21, a sliding rod 22, a positioning rod 23, and a positioning assembly 24. The positioning assembly 24 is located at one end of the sliding groove 11 and includes a positioning plate 241, a reset spring 242, and a positioning pin 243. A guide hole 2411 is provided on the positioning plate 241. A top ring 2431 is provided at one end of the positioning pin 243, and the other end of the positioning pin 243 is set as an inclined surface. The positioning pin 243 is slidably connected within the guide hole 2411. The reset spring 242 is sleeved on the positioning pin 243. In its natural state, one end of the reset spring 242 is fixedly connected to the top ring 2431, and the other end of the reset spring 242 is fixedly connected to the positioning plate 241. The sliding rod 22 slides... The moving mechanism 3 is mounted in the sliding groove 11. The drive rod 21 is fixedly connected to the end of the sliding rod 22 away from the positioning component 24. The positioning rod 23 is rotatably connected to the other end of the sliding rod 22. When the moving plate 31 moves towards the lifting sliding plate 1 through the moving component 32, the drive lever 312 moves the drive rod 21 to slide in the sliding groove 11, causing the positioning rod 23 to slide. The positioning rod 23 slides upward along the guide hole 2411 through the inclined surface of the positioning pin 243, locking the positioning pin 243 with the positioning hole 311, thus locking the moving mechanism 3 onto the lifting moving plate 31. A reset rod 5 is provided on the drive rod 21. The reset rod 5 drives the sliding rod 22 to rotate in the sliding groove 11 through the drive rod 21, and then slides along the reset groove 12 through the reset rod 5 to cause the positioning pin 243 to receive the tension of the reset spring 242, thus unlocking the positioning pin 243 from the positioning hole 311.

[0034] Reference Figure 4The rotating assembly 33 includes a support rod 331, a first connecting rod 332, a second connecting rod 333, and a drive push rod 334. One end of the support rod 331 is rotatably connected to the moving plate 31. One end of the first connecting rod 332 is rotatably connected to the moving plate 31. One end of the second connecting rod 333 is rotatably connected to the other end of the first connecting rod 332, and the other end of the second connecting rod 333 is rotatably connected to the middle of the support rod 331. The base end of the drive push rod 334 is rotatably connected to the moving plate 31, and the working end of the drive push rod 334 is rotatably connected to one side of the other end of the first connecting rod 332. The drive push rod 334 pushes and drives the first connecting rod 332 to rotate. When the push rod 334 is driven to its maximum position, the first link 332 and the second link 333 are collinear and form a dead point position, so that the support rod 331 provides reliable support. The moving component 32 includes a motor 321 and a drive wheel 322. The base of the motor 321 is fixedly connected to the support rod 331, and the drive wheel 322 is rotatably connected to the other end of the support rod 331. The working end of the motor 321 is connected to the drive wheel 322. The motor 321 provides power for the rotation of the drive wheel 322 to drive the welfare seat to move. When the welfare seat moves into the vehicle, the push rod 334 returns, causing the support rod 331 to drive the moving component 32 to fold and move into the vehicle.

[0035] Reference Figure 5 The fixing mechanism 4 includes a fixing sleeve 41, a sliding sleeve 42, a locking sleeve 43, multiple sets of top springs 44, multiple sets of fixing springs 45, and multiple sets of fixing pins 46. The bottom end of the fixing sleeve 41 is fixedly connected to the moving plate 31. Multiple sets of fixing holes 411 are provided on the top end of the fixing sleeve 41. Multiple sets of fixing springs 45 are respectively disposed in the fixing holes 411. The fixing pins 46 are slidably disposed in the fixing holes 411. One end of the fixing spring 45 is fixedly connected to one end of the fixing pin 46, and the other end of the fixing spring 45 is fixedly connected to the bottom of the fixing hole 411. The other end of the fixing pin 46 is an inclined surface. The sliding sleeve 42 is slidably disposed in the fixing sleeve 41. One end of each set of top springs 44 is fixedly connected to the bottom of the fixing sleeve 41. The other end of multiple top springs 44 is fixedly connected to the bottom of the sliding sleeve 42. The locking sleeve 43 is provided with a locking hole 431. The locking sleeve 43 is located at the bottom of the welfare seat. When installing the welfare seat, the bottom locking sleeve 43 is aligned with the sliding sleeve 42 in the fixed sleeve 41 and pressed down. The locking hole 431 is aligned with the fixed hole 411. The fixing spring 45 pushes the fixing pin 46 into the locking hole 431, so that the welfare seat is fixed on the moving plate 31. When the welfare seat is lifted alone, it is disengaged from the locking hole 431 through the inclined surface of the fixing pin 46, so that the fixing pin 46 is unlocked. The sliding sleeve 42 is pushed upward by the top spring 44, so that the fixing pin 46 is retracted into the fixing hole 411 to assist the welfare seat in detaching.

[0036] The working principle of the movable device for welfare seating equipment in this application is as follows: the seat is connected to the movable plate 31 through the fixing mechanism 4 to ensure the welfare seat is stable. The locking sleeve 43 at the bottom of the welfare seat is aligned with the fixing sleeve 41 on the movable plate 31. The welfare seat is pressed down. During the pressing process, the locking hole 431 of the locking sleeve 43 and the fixing hole 411 of the fixing sleeve 41 are gradually aligned. The fixing spring 45 in the fixing hole 411 pushes the fixing pin 46 into the locking hole 431, directly fixing the seat to the movable plate 31. The top spring 44 in the fixing sleeve 41 supports the sliding sleeve 42. During installation, the seat is moved along with the sliding sleeve 42. The seat retracts, providing a restoring force for subsequent unlocking. The rotating assembly 33 and the moving assembly 32 are initially folded. The drive push rod 334 is activated, pushing the first link 332 to rotate, which in turn drives the second link 333. When the drive push rod 334 reaches its maximum stroke, the first link 332 and the second link 333 are collinear, forming a dead point position, ensuring stable support for the support rod 331. The moving assembly 32 contacts the ground, preparing for movement. The motor 321 of the moving assembly 32 is activated, driving the drive wheel 322 to rotate. The drive wheel 322 transmits power through the support rod 331, moving the entire moving plate 31. When the mechanism needs to be moved and mounted, the moving plate 31 moves to the lifting sliding plate 1. As the moving plate 31 approaches the lifting sliding plate 1, the drive lever 312 at the bottom of the moving plate 31 actuates the drive rod 21 on the lifting sliding plate 1. The drive rod 21 drives the sliding rod 22 to slide within the sliding groove 11, thereby pushing the positioning rod 23 to move. The positioning rod 23 presses against the inclined surface of the positioning pin 243, causing the positioning pin 243 to slide upward along the guide hole 2411 of the positioning plate 241, and finally engage with the positioning hole 311 of the moving plate 31, locking the moving mechanism 3 onto the lifting sliding plate 1. When unlocking, after rotating the reset rod 5, the reset rod 5 moves along the reset groove 12. The drive rod 21 slides in the opposite direction in the sliding groove 11, thereby pulling the sliding rod 22 and the positioning rod 23 to reset. The positioning pin 243 unlocks the moving plate 31 and the lifting sliding plate 1 by retracting the reset spring 242. When the seat needs to be removed separately, lift the seat up. The locking sleeve 43 at the bottom of the seat presses against the inclined surface of the fixing pin 46, forcing the fixing pin 46 to compress the fixing spring 45 and retract into the fixing hole 411. After the fixing pin 46 disengages from the locking hole 431, the top spring 44 in the fixing sleeve 41 releases its force, pushes the sliding sleeve 42 upward, and further pushes the locking sleeve 43 upward, assisting the seat to completely disengage from the moving plate 31.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
