In particular, with reference to fig. 2, in an exemplary embodiment of the present invention, the upper beam 201 comprises a first portion 2001 and two second portions 2002, wherein the first portion 2001 comprises two first plates 20011, the two first plates 20011 are identical to each other in shape, both approximating an "n" shape, and the two first plates 20011 are parallel to and spaced apart from each other. Two second portions 2002 are respectively located at two end portions of the first portion 2001, each second portion 2002 comprises a second plate 20022, the shapes of the second plates 20022 of the two second portions 2002 are identical to each other, and the second plates 20022 of the two second portions 2002 are parallel to each other and are both located between the two first plates 20011; the first plate 20011 and the second plate 20022 are joined to each other to form the shape of the upper beam 201 as shown in the drawings, but the shape of the upper beam 201 of the present invention is not limited thereto, and it can be adjusted according to the actual application.

In an exemplary embodiment of the present invention, the number of the car top sheaves 202 may be set to two, and each car top sheave 202 may be installed to two first plates 20011 and be located between the two first plates 20011. The number of the first guide shoe 203 and the safety gear 204 may be respectively set to two, one first guide shoe 203 and one safety gear 204 may be mounted to one second plate 20022, and the other first guide shoe 203 and the other safety gear 204 may be mounted to the other second plate 20022, and the first guide shoe 203 and the safety gear 204 may be mounted up and down on the second plate 20022.

In an exemplary embodiment of the present invention, the first guide shoe 203 may be located above the safety gear 204, but the present invention is not limited thereto, and the positions of the first guide shoe 203 and the safety gear 204 may be adjusted relatively.

Because the first guide shoe 203 and the safety gear 204 are mounted on the side surface of the upper beam 201, the relative positions of the first guide shoe 203 and the safety gear 204 are easy to adjust, the influence of the height of the first guide shoe 203 on the shaft is avoided, and the shaft space is saved.

Furthermore, the car of the present invention may further include a second guide shoe 51, and the second guide shoe 51 may be located at a lower portion of the side of the car body 10.

In an exemplary embodiment of the present invention, the number of the second guide shoes 51 may be set to two, and the two second guide shoes 51 are respectively disposed at lower portions of the two columns 5 and aligned with the first guide shoes 203 in a vertical direction. However, the present invention is not limited to this, and the position of the second guide shoe 51 in the vertical direction can be adjusted according to practical application conditions.

Referring to fig. 4 in cooperation, in the exemplary embodiment of the present invention, the number of the buffering members 41 may be set to four, but the number of the buffering members 41 may be selected as needed, for example, may be set to 2 to 10. In the illustrated embodiment, the car is square, but it may be provided in other shapes, such as a semicircle (or circular arc), a triangle, etc., and the number of the buffers 41 may be selected according to the shape of the car.

Hereinafter, specific positions of the buffer members 41 will be described by taking the case where four buffer members 41 are provided as an example.

In an exemplary embodiment of the present invention, four buffer supports 40 may be provided around the car bottom 4. Preferably, the buffer bracket 40 is provided at a corner of the car bottom. The cushion 41 may be mounted to the cushion bracket 40. The number of the buffer brackets 40 is equal to the number of the buffers 41.

In an exemplary embodiment of the present invention, the installation plane of the buffer 41 may be higher than the plane of the car bottom 4, and the bottom surface of the buffer 41 is lower than the plane of the car bottom 4. Therefore, the thickness of the car bottom can be further reduced while ensuring a sufficient cushioning effect.

Alternatively, in another embodiment of the present invention, four buffer stoppers (not shown) may be provided around the car bottom 4, and the buffer 41 may be fixed at a position of the pit surface corresponding to the buffer stopper of the car bottom 4. The number of the buffer stop blocks is not limited to this, and the number of the buffer stop blocks is equal to the number of the buffers.

In the design of conventional car bottom bolster, the bolster often arranges under the car, nevertheless the utility model discloses arrange car bottom bolster around at the bottom of the car, consequently the distance between car bottom plane and the pit plane no longer receives the influence in bolster space.

With the cushion member 41 provided as described above, the car bottom 4 can be maximally close to the hoistway pit plane when colliding with the ground.

The buffer 41 may be made of a polymer elastic material, and thus may absorb impact and noise when the car roof reaches the end portion.

In an exemplary embodiment of the present invention, the car roof 2 may be provided with a reinforcement to improve the rigidity and strength of the car.
