The following examples are for illustrative purposes only. The various embodiments may be combined, and are not limited to what is presented in the following single embodiment.

Referring to fig. 1 to 2, the present invention provides an embodiment of a cab back panel, including: the automobile metal plate connecting structure comprises a body 1, wherein the body 1 can be made of low-carbon steel, connecting structures are arranged on the edges of the periphery of the body 1 and are used for being matched with an automobile metal plate, through holes can be formed in the connecting structures, and then the edges of the body 1 are riveted or welded with the automobile metal plate; the middle upper part of the body 1 forms a first recess 11 backwards, the structure of the first recess 11 can be formed by stamping, the upper inner side in the first recess 11 is a first inner wall 111, the lower inner side of the first recess 11 comprises a second inner wall 112, a third inner wall 113 and a fourth inner wall 114, the depth of the first inner wall 111 is equal to the sum of the depths of the second inner wall 112, the third inner wall 113 and the fourth inner wall 114, and the edges of the second inner wall 112, the third inner wall 113, the fourth inner wall 114 and the body 1 form a second-order step structure; the bottom of the first recess 11 is provided with a window 110, and the window 110 is used for installing a baffle. Through the structural design to first sunken 11, just the degree of depth of first inner wall 111 equals the degree of depth sum of second inner wall 112, third inner wall 113 and fourth inner wall 114, second inner wall 112 third inner wall 113 fourth inner wall 114 with the edge of body 1 forms second order stair structure, and when stair structure made the seat to incline backward, can have as many strong points and the local structural strength who supports as far as possible with the back panel and increase, the increase driver's cabin space of first sunken 11, can fully adjust back angle, improve the travelling comfort.

In this embodiment, referring to fig. 1, the third inner wall 113 is parallel to the edge of the body 1. Optionally, the depth of the second inner wall 112 is D1, and D1 is between 105 mm and 142 mm. Optionally, the depth of the third inner wall 113 is D2, and D2 is 1/2D1 ± 30. Make the back angle of seat can increase, guaranteed space design and structural strength's problem again simultaneously for can not influence boxcar's conventional size, structural strength can reach the requirement at this scope. The backrest angle of the seat may be up to 20 °.

In this embodiment, referring to fig. 1, a second recess 115 is disposed at the bottom of the first recess 11, the second recess 115 protrudes forward, and the window 110 is disposed on the second recess 115. The second recess 115 is arranged to effectively protect the baffle plate on the window 110, for example, when the window 110 is glazed, the second recess 115 is recessed forward, so that the glass window does not protrude in the front-rear direction of the back panel.

In this embodiment, referring to fig. 1, a lower plate 116 is disposed in front of the edge of the body 1 and the first inner wall 111, and the lower plate 116 is parallel to the up-down direction and perpendicular to the front-back direction. The setting of lower dull and stereotyped 116 makes corresponding to carry out sunken design to the back panel, and when the seat leaned on behind, the below of seat generally does not contact with the back panel, and lower dull and stereotyped 116's design structure is simpler, and is optional, be equipped with a plurality of convex ribs to the back down on the dull and stereotyped 116, protruding rib stamping forming. Through the design of protruding muscle for the structure of back panel is strengthened. Optionally, the ribs include a first rib 1161 and a second rib 1162, the length of the first rib 1161 is greater than the length of the second rib 1162, and the first rib 1161 is located on the lower flat plate 116 and extends to the second inner wall 112 and the third inner wall 113. So that the structural strength of the force bearing point inside the first recess 11 and the lower flat plate 116 are improved. Optionally, the second ribs 1162 are located on two sides of the first rib 1161. Due to the design of the automobile model, the rib structure arranged at the corner of the edge is inconvenient to punch, and the second rib 1162 is only arranged on the lower flat plate 116, so that the processing is easier, and the structural strength is also ensured.

An automobile comprising the cab back panel; also included is a seat that can partially nest within the first recess 11 when the seat is reclined. The back angle of the seat is increased.

To sum up, the utility model discloses a to the structural design of first sunken 11, just the degree of depth of first inner wall 111 equals the degree of depth sum of second inner wall 112, third inner wall 113 and fourth inner wall 114, second inner wall 112 third inner wall 113 fourth inner wall 114 with the edge of body 1 forms second order stair structure, and stair structure makes when the seat inclines backward, can have the local structural strength increase of the strong and support of strong enough strong points and support with the back panel, the increase of first sunken 11 the driver's cabin space, can fully adjust back angle, improves the travelling comfort. Therefore, the utility model effectively overcomes various defects in the prior art and has high industrial utilization value.
