Detailed Description

The present invention will be described in detail with reference to the accompanying drawings, wherein for convenience of illustration, the drawings showing the structure of the device are not to scale and are partially enlarged, and the drawings are only examples, which should not limit the scope of the invention. It should be noted that the drawings are in simplified form and are not to precise scale, which is only used for the purpose of facilitating and clearly assisting in the description of the embodiments of the present invention.

As shown in fig. 1, 2, 3 and 4, the passenger car door armrest of the present embodiment includes an armrest body 1 and a reinforcing guard rail 2 connected to the armrest body 1. The structure of the handrail main body 1 is the same as the structure of an upper handrail and a lower handrail of a conventional tourist bus at the door, the reinforced guardrail 2 is connected with a waist rail (middle part) of the handrail main body 1 through the connecting piece 3, the upper end of the reinforced guardrail 2 is fixed with a side wall framework of a bus body, and the lower end of the reinforced guardrail is fixed with a floor framework of the bus body. The connecting piece 3 of this embodiment includes a connecting rod 3-1 and a connecting tee 3-2, and both ends of the connecting rod 3-1 are respectively connected with the wale of the handrail main body 1 and the reinforcing guardrail 2 through the connecting tee 3-2.

The installation of the armrest of the present invention in a vehicle will be further described with reference to a specific embodiment. As shown in fig. 5, when the handrail main body 1 is installed on a side wall of a passenger car center door step, the installation position and structure of the handrail main body are unchanged, and the handrail main body 1 is fixed to the inner side wall of the passenger car through 3 installation points (a, b, c). It is fixed mutually (strengthening guardrail 2 and handrail main part 1 and being located same one side of door) mutually through side wall skeleton M and the floor skeleton N of fixing base and door side respectively to strengthen guardrail 2, and the accessible increases the backing plate and comes the adjusting position between strengthening guardrail 2 and side wall skeleton M and the floor skeleton N, and in this embodiment, the distance between the upper end of strengthening guardrail 2 and the floor is 475mm, and the distance between lower extreme and the side wall skeleton is 450mm, can provide for placing of fire extinguisher and dodge the space. Strengthen both ends 150mm department of guardrail 2 and set up the portion of bending, bend the angle more than R80, can increase the angle of bending as required to avoid because bend and warp and take place the cracked risk of atress in-process. And respectively installing the connecting tee joints 3-2 on the waist beam of the handrail main body 1 and the reinforcing guardrail 2, and then connecting and fixing the handrail main body 1 and the reinforcing guardrail 2 through the connecting rods 3-1 to finish the installation of the handrail.

More specifically, the included angle α between the reinforced guardrail 2 and the side wall framework M and the included angle β between the reinforced guardrail 2 and the floor framework N are kept within 60 degrees, preferably 45 degrees, so as to achieve a better reinforcing effect, because the reinforced guardrail 2 is obliquely supported between the side wall framework M and the floor framework N to play a role of bearing and supporting, a steel pipe with higher strength is preferably selected, a gray twist steel pipe with the wall thickness of 2.0mm and the pipe diameter of phi 32 can be adopted, the aperture of a mounting hole of a fixing seat of the reinforced guardrail 2 can be changed from phi 4 to phi 8.5, and a fixing piece is also changed from a self-tapping nail to an 8mm bolt with the bolt strength of 8.8 grade.

Through setting up the enhancement guardrail, strengthen the guardrail and can support between offside skeleton and the floor skeleton on the one hand, strengthened the intensity of automobile body skeleton, strengthen the guardrail moreover and pass through the connecting rod and link to each other with the handrail main part, also be favorable to increasing the lateral stability of handrail main part. The utility model discloses a reinforced structure has increased one section enhancement guardrail on the basis of original passenger train door handrail, does not destroy former interior trim of car, need not to change former interior trim of car, and the mounted position who strengthens the guardrail moreover is located well door front seat rear portion, can not influence the passenger yet current, and the practicality is good.

Of course, the technical concept of the present invention is not limited to the above embodiments, and many different specific schemes can be obtained according to the concept of the present invention, for example, the supporting angle of the reinforced guardrail, the external dimension, the distance between the reinforced guardrail and the side wall guardrail and the floor, etc. can be adjusted according to the actual condition of the car body; such modifications and equivalents are intended to be included within the scope of the present invention.
