For the convenience of description, refer to Figure 1 、 Figure 2 、 Figure 3, the width direction of the first skeleton 1 is defined as the first direction X, the length direction is the second direction Y, and the height direction is the third direction Z. Wherein, one end of the first skeleton 1 in the first direction X is connected with the door trim a, the other end of the first skeleton 1 in the first direction X is connected with the second skeleton 2, the first skeleton 1 is provided with a hand slot 11, and the hand slot 11 is sequentially provided with a first gripping area 111 and a second gripping area 112 in the third direction Z close to the second skeleton 2. The top of the second skeleton 2 is curved to be provided with an extension 21 close to the hand slot 11, the extension 21 is arranged above the second gripping area 112, in order to improve the touch feeling when the passenger grips, the side wall of the second skeleton 2 away from the hand slot 11 and the side wall of the extension 21 are attached with a skin 3, the skin 3 is in soft contact with the palm, and the touch feeling when the passenger grips is improved.

[0027] In order to avoid the contact of the hand with the first skeleton 1 and the second skeleton 2 when the hand grips, referring to Figure 2 、 Figure 3 , the second gripping area 112 is provided with a first arc surface 1121 protruding away from the second skeleton 2, the chamfer radius of the first arc surface 1121 is 25mm≤R1≤35mm, the junction of the extension 21 and the hand slot 11 is provided with a second arc surface 211 protruding towards the hand slot 11, the chamfer radius of the second arc surface 211 is 8mm≤R2≤10mm, according to the holding shape of the hand, the first arc surface 1121 is provided with a chamfer to match the bending radius of the fingers, and the second arc surface 211 is provided with a chamfer to match the bending radius of the connection between the palm and the fingers, so that the gripping surface in contact with the hand is smooth, and the comfort of the passenger when gripping is improved. Preferably, in the embodiment, the chamfer radius of the first arc surface 1121 is 30mm, and the chamfer radius of the second arc surface 211 is 9mm. The depth H of the hand slot 11 in the third direction Z is greater than or equal to 60mm, so as to avoid the hand contacting the bottom of the hand slot 11 when gripping, which causes discomfort when gripping.

[0028] Further, in order to facilitate positioning when assembling the first skeleton 1 and the second skeleton 2, the side of the first skeleton 1 away from the hand slot 11 is provided with a clamping groove 12, and the side of the second skeleton 2 towards the hand slot 11 is provided with a positioning boss 22 corresponding to the clamping groove 12. Further, in order to improve the overall structural strength of the first skeleton 1 and avoid deformation and damage of the first skeleton 1 caused by excessive gripping force, a reinforcing rib 13 is arranged on the side of the first skeleton 1 away from the hand slot 11 in the second direction Y, and the clamping groove 12 is arranged on the reinforcing rib 13.

[0029] Further, according to the human hand holding shape, in order to make the first curved surface 1121 and the second curved surface 211 more closely contact with the hand, in the first direction X, the distance from the first curved surface 1121 to the door trim a is less than the distance from the second curved surface 211 to the door trim a, and the spacing between the first curved surface 1121 and the second curved surface 211 is L, 5mm≤L≤10mm. Preferably, in the present embodiment, L is 8mm. If L is less than 5mm, the first curved surface 1121 and the second curved surface 211 are close to flush in the third direction Z, which is not easy to fit the human hand holding shape, affects the holding feeling, and if L is greater than 10mm, the bending curvature of the human hand holding is smaller, which is more laborious to grasp the handrail to push open the door, and affects the passenger experience.

[0030] Further, in the prior art, the bottom thickness of the hand holding groove 11 is relatively thin, which cannot provide sufficient support and stability, and passengers feel not stable or easy to slip when grasping, resulting in poor holding feeling when grasping, therefore, in some embodiments, as shown in Figure 2 the cross section in the first direction X, the minimum spacing between the inner wall of the first grasping area 111 and the outer wall of the second skeleton 2 is W, 25mm≤W≤35mm, preferably, in the present embodiment, the spacing W between the first grasping area 111 and the second skeleton 2 is 30mm.

[0031] In some embodiments, according to the ergonomic principle, the height of the second grasping area 112 in the second direction Y is adjusted to M, which meets the size requirement of human hand grasping, 30mm≤M≤35mm, preferably, in the present embodiment, the size of M is 32mm. The depth H of the hand holding groove 11 in the third direction Z is ≥60mm, preferably, in the present embodiment, the depth of the hand holding groove 11 is 70mm.

[0032] Further, in order to facilitate the design of the skin 3, the skin 3 includes a base layer and a foaming layer, one side of the base layer is attached to the side wall of the second skeleton 2, and the other side is attached to the foaming layer. The thickness of the base layer is 0.8mm-1.2mm, and the thickness of the foaming layer is 1.5mm-2.5mm. In the present embodiment, the skin 3 uses 1mm PVC to make the base layer, and the thickness of the foaming layer is 2mm.

[0033] Further, in order to facilitate the support of the extension 21, the top of the first skeleton 1 is provided with a flange plane 14 for supporting the extension 21. Since a pushing force needs to be applied to the second skeleton 2 when the door is opened, in order to avoid the second skeleton 2 from shaking under force, the one end of the reinforcing rib 13 towards the second skeleton 2 is provided with a support boss 131 abutting against the side wall of the second skeleton 2 towards the knob slot 11. Further, in order to avoid stress concentration on the contact surface between the support boss 131 and the second skeleton 2, causing damage to the second skeleton 2, the end of the support boss 131 is provided with a protective arc surface 1131 for contacting the side wall of the knob slot 11.

[0034] In summary, the utility model provides a kind of automobile door handrails, knob slot 11 is sequentially provided with first gripping area 111, second gripping area 112 in third direction Z close to second skeleton 2, the top of second skeleton 2 is bent and is provided with extension 21 towards knob slot 11, extension 21 is arranged above second gripping area 112, the side wall of second skeleton 2 away from knob slot 11, the side wall of extension 21 is attached with skin 3, skin 3 is softly contacted with palm, and the touch when passenger grips is improved.The second gripping area 112 is provided with the first arc surface 1121 protruding away from second skeleton 2, and the chamfer radius of the first arc surface 1121 is 25mm≤R1≤35mm.The junction of extension 21 and knob slot 11 is provided with the second arc surface 211 protruding towards knob slot 11, and the chamfer radius of the second arc surface 211 is 8mm≤R2≤10mm.By setting the first arc surface 1121 and the second arc surface 211, according to the shape of hand holding, the first arc surface 1121 is set to chamfer to fit the bending curvature of finger, and the second arc surface 211 is set to chamfer to fit the bending curvature of the connection between palm and finger, so that the gripping surface in contact with hand is smooth, and the comfort of passenger when gripping is improved.In addition, the depth H of knob slot 11 in third direction Z is greater than or equal to 60mm, so as to avoid the bottom of knob slot 11 being contacted when hand gripping, which causes discomfort when gripping.

[0035] The above is only the preferred embodiment of the utility model, and it should be pointed out that, for ordinary skilled person in the art, without departing from the technical principles of the utility model, a number of improvements and substitutions can be made, and these improvements and substitutions should be regarded as the protection scope of the utility model.
