Technical Field

[0001] The utility model relates to the technical field of electric sightseeing vehicles, in particular to a seat adjustment device for an electric sightseeing vehicle. Background Art

[0002] Electric sightseeing cars are a type of electric vehicles for regional use. They can be divided into tourist sightseeing cars, community house-viewing cars, electric classic cars, small golf carts, etc. They are environmentally friendly electric passenger vehicles specially designed for tourist attractions, parks, large amusement parks, closed communities, and schools. Electric sightseeing cars are battery-powered and do not emit harmful gases that pollute the atmosphere. They can be used after the battery is charged.

[0003] At present, the utility model with the publication number CN218054925U proposes an electric sightseeing car seat adjustment device, including a main board, a side frame, a backboard and an armrest, the top outer wall of the main board is provided with a bearing mechanism, and a baffle is fixedly connected to the middle position of the outer wall of one side of the main board, the outer walls of both ends of one side of the main board are fixedly connected to the second limit plate, the outer walls of both ends of the top of the baffle and the second limit plate are rotatably connected to the second cross bar through a bearing, the backboard is fixedly connected to the circumferential outer wall of the second cross bar, the side frames are respectively fixedly connected to the outer walls of both ends of the main board, and the top outer walls of the side frames are plugged with a movable plate, and the outer walls of both ends of one side of the movable plate are fixedly connected to a clamping plate. The utility model can provide a support effect of the tilt angle for the user sitting on the top of the main board, realize the adjustment effect of the seat back, and the user can place his arms on the top of the movable plate and the armrest, which is convenient for the user to rest, and has strong practicality.

[0004] However, the above-mentioned prior art still has the following deficiencies when used: 1. The main board does not have a tilt adjustment function. When the backboard tilts backward, the main board remains in its original state. At this time, tourists may feel uncomfortable sliding down when leaning on the backboard; 2. When adjusting the tilt angle of the backboard, it is necessary to pull out the card plate inserted in the fixed groove through a pull rod to release the restriction on the movable board, so that the movable board can be moved. When the card plate connects the fixed board with the side frame, the locking effect of the device is achieved. This adjustment method is prone to jamming, which means that the convenience of adjustment is poor.

[0005] To this end, the utility model provides a seat adjustment device for an electric sightseeing vehicle. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: an electric sightseeing car seat adjustment device, comprising a main board 1 and a back board 2, a support is welded to the bottom of the main board 1, and then the main board 1 is installed on the bottom board of the sightseeing car through the support, and a row of windows 11 are provided on the upper end surface of the main board 1. In this embodiment, the windows 11 are rectangular and there are two of them. A rear seat plate 3 and a front support plate 4 are arranged in the window 11, and the rear seat plate 3 and the window 11 are fixedly connected, specifically, the rear seat plate 3 and the window 11 are welded, and the rear end of the front support plate 4 and the front end of the rear seat plate 3 are rotatably connected up and down, specifically, a hinge is installed between the front support plate 4 and the rear seat plate 3, and the front support plate 4 can change the inclination when it swings up and down.

[0023] The bottom of the main board 1 is rotatably connected with a lead screw 5. Specifically, a hanging plate 13 near the front and rear ends is welded at the bottom of the main board 1, and the two ends of the lead screw 5 are rotatably connected to the hanging plate 13. A connecting block 7 is screwed on the lead screw 5, and the top of the connecting block 7 is hingedly connected to the bottom of the front support plate 4 through a support rod 101, wherein a thread sleeve is welded through the connecting block 7 and sleeved on the outside of the lead screw 5. When the lead screw 5 rotates, it will use the screwing action to drive the connecting block 7 to move axially along the lead screw 5, and at this time, the support rod 101 will drive the front support plate 4 to swing.

[0024] The bottom of the back plate 2 is rotatably connected to the main plate 1. The specific implementation structure is that the rear end of the main plate 1 is welded with an ear plate 14, one back plate 2 corresponds to two ear plates 14, and the two ear plates 14 are located on both sides of the back plate 2. The bottom of the back of the back plate 2 is welded with a positioning shaft 21 with both ends rotatably connected to the ear plates 14 through an L-shaped connecting rod, and the gear 6 is fixedly sleeved on the positioning shaft 21. When the back plate 2 rotates, its inclination angle changes. The bottom of the back plate 2 is fixedly provided with a gear 6, and one end of the lead screw 5 is fixedly sleeved with a worm sleeve 51 meshing with the gear 6. When the lead screw 5 rotates, the worm sleeve 51 drives the gear 6 to rotate, thereby driving the back plate 2 to swing.

[0025] In this embodiment, a downwardly pressed arc-shaped baffle 41 is welded to the front end of the front support plate 4, and the inner arc surface of the arc-shaped baffle 41 faces rearward and downward. The outer arc wall of the arc-shaped baffle 41 fits in the front side gap in the window 11. This arc-shaped baffle 41 plays an anti-pinch role to prevent the gap between the front support plate 4 and the window 11 from pinching the occupant.

[0026] In this embodiment, a knob plate 52 is welded to one end of the lead screw 5 , and the knob plate 52 is an operating component for controlling the rotation of the lead screw 5 by hand.

[0027] In this embodiment, an arc-shaped support plate 22 is welded on one side of the back plate 2 close to the outside of the main board 1, and the inner arc surface of the arc-shaped support plate 22 faces downward. The upper arc surface of the arc-shaped support plate 22 serves as an armrest, which is convenient for the passengers to put their arms on the arc-shaped support plate 22, and also convenient for the passengers to hold it manually, thereby improving the stability of riding. An arc-shaped limiting plate 12 is welded on the upper end surface of the main board 1, which is close to both ends and is plugged into the arc-shaped support plate 22. This arc-shaped limiting plate 12 can improve the strength of the arc-shaped support plate 22.

[0028] Working principle: when in use, the passenger sits on the rear seat plate 3 with the thighs blocked by the front support plate 4 and the back plate against the back plate 2. When the passenger is tired of riding, the user manually holds the knob 5 to twist the lead screw 5, and the connecting block 7 moves under the rotation action, and the support 101 will drive the front support plate 4 to swing upward. At the same time, the rotation of the worm sleeve 51 will drive the gear 6, and the gear 6 will drive the back plate 2 to tilt backward. At this time, the user's backward inclination angle increases, and there will be no problem of sliding down under the obstruction of the front support plate 4, which greatly improves the riding comfort.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
