In the present application, the opening direction of the door is defined as the depth direction Y, the width direction X is perpendicular to the depth direction Y on the horizontal plane, and the vertical direction (gravity direction) is the height direction Z.

The car apparatus 10 further includes a first fixed frame 12 and a second fixed frame 13. The first fixing frame 12 and the second fixing frame 13 are disposed at intervals along the depth direction Y of the car frame 11, and the first fixing frame 12 and the second fixing frame 13 are respectively disposed around the car frame 11 for reinforcing the periphery of the car frame 11. The car frame 11, the first fixed frame 12 and the second fixed frame 13 together form a rigid frame structure, so that the car frame has higher strength, plays a role in reinforcement, improves the stability of the car equipment 10, and can have higher load of the car equipment 10.

The fixed frame is arranged around the car bottom, the car wall and the car top.

The first fixing frame 12 and the car frame 11 may be fixedly connected, so that the first fixing frame 12 and the car frame 11 are relatively fixed, and the first fixing frame 12 and the car frame 11 may be connected by welding, riveting, bolting, etc.

The first guide mechanism 14 is arranged on the first fixed frame 12, the first guide mechanism 14 is also arranged on the second fixed frame 13, and the first guide mechanism 14 is used for being in sliding connection with the first guide rail 20 of the elevator 100, so that the running of the car equipment 10 along the extending direction of the first guide rail 20 is guided, and the running process of the car equipment 10 can be more stable.

In addition, the car frame 11 is further provided with an auxiliary guide 15, and the auxiliary guide 15 is used for being slidably connected with the second guide rail 30 of the elevator 100 so as to guide the car device 10 to stably run along the extending direction of the second guide rail 30, so that the running process of the car device 10 and the car device can be further stabilized.

In this embodiment, compared to the existing car apparatus 10 in which three sets of gantry frames 12 are provided to fix the car frame 11, the car apparatus 10 provided in this embodiment of the present application only includes two sets of fixing frames (the first fixing frame 12 and the second fixing frame 13), so that the strength of the car apparatus 10 is higher, and the car apparatus has a higher load, and materials for fixing the car frame 11 are saved.

In addition, the auxiliary guide 15, which is further provided on the basis of the first guide mechanism 14 provided on the first and second fixed frames 12 and 13, can maintain smooth running of the car apparatus 10, so that the car apparatus 10 is more stable with only two sets of fixed frames.

In summary, the present embodiment reduces the existing three sets of the gantry frames 12 into two sets of the fixed frames 12, saves materials and reduces costs, and simultaneously provides the auxiliary guide 15 to maintain the original running stability of the car apparatus 10.

In some embodiments, referring to fig. 1, the first fixing frame 12 and the second fixing frame 13 are respectively disposed on two sides of a first center line P1 of the car frame 11 parallel to the width direction X, and it is understood that the first fixing frame 12 is disposed on one side of the first center line P1, and the second fixing frame 13 is disposed on the other side of the first center line P1.
