Description

Automatic lifting auxiliary seat

This creation is about an auxiliary seat, especially an automatic lifting auxiliary seat that can greatly improve the convenience of operation.

By the way, it is very difficult for people with mobility impairment to get on and off the car, because some people with mobility impairments cannot move from the wheelchair to the car seat, and usually need the assistance of others to get on the car or get on the car seat smoothly. Move to a wheelchair.

The current mobile seats used in automobiles still use screw locking methods for seat installation. The so-called screw locking means that the screw holes on the seat need to be aligned with the screw holes on the moving mechanism. While aligning, the installer must personally determine the position through his eyes and then use the screws to lock the installation, which makes the installation of the mobile seat quite difficult and inconvenient. Moreover, the conventional mobile seat is a separate steering seat. The cost of the chair is also relatively high.

In addition, some companies have designed car seat devices with steering and movement in response to the above needs, so that the seat can be moved out of the car door slightly, so that people with limited mobility can get on and off the vehicle. However, there are still some shortcomings, such as: if the width of the door is too small, the passenger's feet are easy to touch the door frame, and it is not easy to slip out of the door, and if the roof height is insufficient, if the height of the passenger is taller or lower It is impossible to appropriately lower or raise the height of the seat, resulting in inconvenience in getting in and out.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the creators of this creation and the related manufacturers engaged in this industry urgently want to study and improve.

In this regard, in order to effectively solve the above-mentioned problems, the main purpose of this creation is to provide an automatic lifting auxiliary seat that greatly improves the convenience of operation.

The secondary purpose of this creation is to provide a very labor-saving automatic lifting auxiliary seat.

In order to achieve the above objective, this creative department provides an automatic lifting auxiliary seat, which includes a seat frame, a lifting mechanism and a moving mechanism. The seat frame is arranged on the bottom of a seat inside an automobile body and is connected The seat is connected and fixed, the seat frame is installed on the moving mechanism, and the moving mechanism is installed on the lifting mechanism. The lifting mechanism has a screw rod. The upper end of the screw rod is provided with a disc gear. The disc gear rotates to drive the screw to rotate to drive the moving mechanism and the seat frame to move up and down. The moving mechanism is installed under the seat frame and has a screw, a motor and a slide rail set to drive The seat frame moves forward or backward.

In an embodiment, at least one blocking block is further provided on the lower side of the seat frame, and a blocking piece is further provided on the sliding rod.

In one embodiment, there is a control box, and the lifting mechanism is installed in the control box.

In one embodiment, there is a slide rail assembled in the car body and correspondingly arranged below the sliding plate body, and a sliding plate body is installed on the upper side of the slide rail group to slide back and forth on the slide rail group There is a latch below the sliding plate body to adjust the position of the sliding plate body and prevent it from moving, and the control box is correspondingly arranged on the sliding plate body.

In one embodiment, the sliding plate body is further provided with a shaft rod, and the shaft rod is connected with the control box, so that the seat frame can be turned at an angle, and the rotation angle is between 0 and 135. Between degrees.

In an embodiment, at least one buckle is further formed on the seat frame, and the buckle is correspondingly clamped on the sliding plate body, and is used to fix the seat frame to prevent it from moving.

In one embodiment, a control unit is further provided outside the control box, and the control unit is used to control the up, down, front, and back movement of the seat frame.

In one embodiment, there is a switch provided outside the control box, and the switch is electrically connected to the motor.

Through the design of this structure, when a occupant sits on the seat and wants to get off the car, first the auxiliary seat is manually slid to a sliding plate by a manipulator under the seat frame. At the position of the entrance and exit of the car door, unlock the seat frame buckle on the sliding plate body to control the control unit, move the control unit upwards, so that the seat frame drives the disc through the drive gear The gear rotates to drive the screw to rotate, which drives the seat frame up to the required height and then stops. Then, the operator manually steers the seat and the seat frame 90 degrees to make the seat frame up to the required height. The occupant faces the door of the car, and finally moves the control unit forward to make the seat frame move beyond the door, and the occupant can get off the car smoothly. With the structure design of the automatic lifting auxiliary seat, the operator can operate very well. Convenient and labor-saving.
