Description

Technical Field

[0001] The utility model relates to the technical field of logistics elevators, and particularly relates to a car door panel structure. Background Art

[0002] With the rapid development of social technology, the demand for logistics elevator storage equipment in the current industry is also becoming more and more extensive. Due to the large size of the logistics storage system equipment, the requirement for the space utilization rate of the car (transporting product boxes) is also getting higher and higher. Generally, the front door machine of the car on the market adopts the structure of the traditional elevator door system, and the door panel hanging under the door machine adopts the full-thickness size design. See Figure 1 As shown, the door panel structure is that the upper head and the lower head are welded to the upper and lower ends of the door panel main body. The upper and lower heads are of the same width as the door panel main body, and the door panel main body is also of the same width as the sill. In this way, the transport platform can only be close to the edge of the sill. Such a structural design makes the car space smaller and the space utilization rate of the car is not high. Content of the Utility Model

[0003] To overcome the above-mentioned problems, the purpose of the utility model is to provide a car door panel structure, which reduces the thickness of the door panel main body. The upper end of the door panel main body is bent to replace the function of the original upper head, and only a fixing bracket capable of fixing the door slider needs to be arranged at the lower end and welded to the door panel main body. The car space becomes larger, and the length of the transport platform can exceed the edge of the sill, increasing the space utilization rate of the car.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a car door panel structure, including a door panel main body, a first reinforcing rib, a second reinforcing rib and a fixing bracket. A folded edge is arranged at the upper end of the door panel main body, and the folded edge is formed by bending the upper end of the door panel main body and includes a horizontal edge. The first reinforcing rib is arranged at the upper end of the door panel main body to ensure the strength of the hanging point of the door panel main body. The second reinforcing rib is arranged in the middle of the door panel main body to prevent the door panel main body from deforming. The fixing bracket is fixed to the lower end of the door panel main body by welding.

[0005] Further, both the first reinforcing rib and the second reinforcing rib are fixed to the door panel main body by welding.

[0006] Further, there are three first reinforcing ribs, which are vertically arranged at the upper end of the door panel main body.

[0007] Further, there are two second reinforcing ribs, which are horizontally arranged on the door panel main body.

[0008] Further, the thickness of the door panel main body is 15 mm.

[0009] Further, the main door panel is fixed to the upper sill of the door machine through the horizontal edge. The upper sill of the door machine is fixed to the upper end of the car. A transportation platform is arranged inside the car. The upper sill of the door machine drives the main door panel to move horizontally through a motor drive.

[0010] Further, the main door panel fixes the door slider through the fixing bracket, and the door slider is arranged in the sill slot.

[0011] The beneficial effects of the present utility model are:

[0012] The present utility model reduces the thickness of the main door panel. The bending at the upper end of the main door panel replaces the function of the original upper head. Only a fixing bracket capable of fixing the door slider needs to be arranged at the lower end and welded to the main door panel. There is no longer a need for the traditional structure of upper and lower heads with the same width as the main door panel. The thickness of the main door panel corresponding to the position of the transportation platform is smaller than the width of the sill. The space of the car becomes larger, and the length of the transportation platform can exceed the edge of the sill, increasing the utilization rate of the car space. Description of the Drawings

[0019] The following elaborates on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0020] See Figures 2-5, this embodiment discloses a car door panel structure, including a door panel main body 1, a first reinforcing rib 2, a second reinforcing rib 3 and a fixing bracket 4. A hem 5 is provided at the upper end of the door panel main body 1. The first reinforcing rib 2 is arranged at the upper end of the door panel main body 1 to ensure the strength of the suspension point of the door panel main body 1. The second reinforcing rib 3 is arranged in the middle of the door panel main body 1 to prevent the door panel main body 1 from deforming. The fixing bracket 4 is fixed to the lower end of the door panel main body 1 by welding. The thickness of the door panel main body 1 is 15 mm. Both the first reinforcing rib 2 and the second reinforcing rib 3 are fixed to the door panel main body 1 by welding.

[0021] There are three first reinforcing ribs 2, arranged vertically at the upper end of the door panel main body 1, and two second reinforcing ribs 3, arranged horizontally on the door panel main body 1.

[0022] The hem 5 is formed by bending the upper end of the door panel main body 1 and includes a horizontal edge. The door panel main body 1 is fixed to the upper door sill 7 of the door machine through the horizontal edge. The upper door sill 7 of the door machine is fixed to the upper end of the car 6. A transportation platform 8 is arranged inside the car 6. The door panel main body 1 fixes the door slider 9 through the fixing bracket 4. The door slider 9 is arranged in the notch of the floor sill 10. The upper door sill 7 of the door machine drives the door panel main body 1 to move horizontally through the motor drive.

[0023] The utility model reduces the thickness of the door panel main body 1 to 15 mm. The bending of the upper end of the door panel main body 1 replaces the function of the original upper head. Only a fixing bracket 4 that can fix the door slider 9 needs to be arranged at the lower end and welded to the door panel main body 1. There is no longer a need for the traditional structure of upper and lower heads with the same width as the door panel main body. The thickness of the door panel main body 1 corresponding to the position of the transportation platform 8 is smaller than the width of the floor sill 10. The space of the car 6 becomes larger, and the length of the transportation platform 8 can exceed the edge of the floor sill 10, increasing the utilization rate of the car space.
