Description

Automobile-used electric toilet capable of being converted into squatting position for use

Technical Field

The utility model relates to an automobile-used electric toilet bowl that can use with the conversion of position of squatting belongs to the supporting sanitary installation field of train.

Background

The single squatting pan or toilet bowl is adopted on the train at present, and the squatting pan is relatively sanitary to use, but has the puzzlement of squatting down and getting up difficulty to old passenger, the passenger that the size is fat. The toilet bowl can solve the problem, but many passengers feel unhygienic and are not used to the toilet bowl, and the requirements of the passengers are difficult to meet. The general idea for solving the problem is to design a squatting and sitting dual-purpose toilet at the same squatting position of the same toilet.

Because the space of the train toilet is narrow, especially the space in front of and behind the toilet is very limited, the design of the squatting and sitting dual-purpose toilet bowl is very difficult, and the design is mainly shown in the following two aspects:

1. the space in front and back of the toilet user is narrow, the seat ring cannot be forwards out when put down, otherwise, the toilet user is inconvenient and even cannot sit down; when the seat ring is folded, the space occupied forwards must be reduced as much as possible, otherwise, the toilet using the squatting pan is inconvenient and even cannot be used for squatting.

2. The folded toilet is low in position, so that male passengers frequently urinate in standing mode, and the folded toilet is easily polluted.

In addition to solving the above problems, it is necessary to select between a manual, electric, or automatic seat folding and setting-down mode. Because the toilet on the train is a public sanitary space and is almost in a state of being used in line all day and night, the seat ring is not required to be folded and put down, and the labor and the time are wasted, otherwise, the toilet is difficult to adapt to the personnel in the toilet, the time for using the toilet once is prolonged, and the use efficiency is reduced.

Detailed Description

As shown in figure 1, the electric toilet for the vehicle capable of being converted from the squatting position comprises a ledge 1, a power supply control button of a seat ring 2 and a lifting type rotating mechanism arranged between the ledge 1 and the seat ring 2; the vertical rear portion of fixing at position pothole 27 squats of ledge 1, slewing mechanism includes lifting unit, runner assembly and servo motor 3, seat circle 2 passes through runner assembly and installs on lifting unit, servo motor 3 installs on lifting unit, lifting unit installs on ledge 1, utilizes over-and-under type slewing mechanism to make seat circle 2 go up and down on ledge 1 to utilize the lift of seat circle 2 to make seat circle 2 rotate, realize that seat circle 2 folds up or lays flat. By utilizing the rotation and stop positioning characteristics of the servo motor, when a passenger needs to use the toilet bowl for defecation, the seat ring 2 can be rotated to a horizontal state through the lifting type rotating mechanism only by pressing the power supply control button; when the passenger needs to use the squatting position for toilet, the seat ring 2 can be turned upwards to the vertical state through the rotating component. By the arrangement, when the seat ring 2 is put down, the front and back positions of the ring opening of the seat ring 2 are consistent with the front and back positions of the squatting pot hole 27 designed originally, so that a toilet user can sit down in enough space; after the seat ring 2 is folded, the total thickness of the seat ring 2 and the ledge 1 can be designed to be less than 20cm, namely the occupied front and rear space is not more than 20cm, and the front and rear space of the toilet can still meet the squatting requirement of a toilet user. Since the seat 2 and the elevating/lowering type rotation mechanism can be raised as a whole, the adverse effect of this seat 2 and the ledge 1 on the front and rear spaces is substantially eliminated. Because the seat ring 2 can be lifted upwards after being folded, the male can be prevented from polluting the seat ring 2 when standing to urinate. The whole operation only needs to press the power control button, so that the seat ring 2 can be folded and put down conveniently and quickly, and the squatting and sitting modes can be switched freely.

The lifting assembly comprises two sliding pipes 6 sleeved on the frame columns 4 on the two sides, two racks 7 arranged between the two sliding pipes 6 and respectively close to the two sliding pipes 6, and two gears 8 respectively meshed with the two racks 7 and walking on the two racks 7, wherein the two gears 8 are driven by the servo motor 3 through shaft parts. When the motor rotates, the two sliding pipes 6 can be driven to slide up and down along the frame columns 4 on the two sides of the ledge 1 respectively. In order to enhance the consistency of the up-and-down sliding of the two sliding pipes 6, connecting plates 9 are arranged at the upper end and the lower end between the two sliding pipes 6.

The runner assembly includes pivot 10 and support 11, the support has two, installs respectively on two slide pipes 6, all be provided with horizontal pivot hole on 2 rear ends of seat circle and the

support

11, 10 middle sections of pivot are located the pivot hole of 2 rear ends of seat circle, and the both ends of pivot 10 are located the pivot hole of controlling two supports 11, pivot 10 can rotate in the pivot hole.

The gear 8 is fixedly arranged on a rotating shaft 10, and the servo motor 3 is arranged outside a support 11 on one side of the ledge 1 and is linked with one end of the rotating shaft 10 on the side.

With the above arrangement, the seat 2 can rotate about the rotation axis 10. Meanwhile, the servo motor 3 drives the rotating shaft 10 to rotate, the rotating shaft drives the gear 8 to rotate, and the gear 8 runs on the rack 7, so that the sliding pipe and the seat ring 2 arranged on the sliding pipe 6 can move up and down on the ledge 1 together.
