Abstract
The invention relates to a lightweight fulcrum bar of a headrest of an automobile, which comprises a supporting portion, a connecting portion and an adjusting guiding portion. The adjusting guiding portion consists of two bilateral steel tubes, the front end of the adjusting guiding portion is connected with the connecting portion, the connecting portion comprises two bilateral bent steel tubes, the two bent steel tubes are respectively connected with the two steel tubes of the guiding adjusting portion, the supporting portion is a bilateral U-shaped steel tube, and lower ends of two supporting legs of the U-shaped steel tube are respectively connected with upper ends of the two steel tubes of the guiding adjusting portion. The lightweight fulcrum bar of the headrest of the automobile is simple in structure, light in weight, high in material strength and low in material consumption, and cost can be saved.
Description
Technical field
The present invention relates to the vehicular spare parts field, particularly a kind of lightweight automotive headrest pole.
Background technology
The effect of manned vehicle headrest generally is for improving a kind of auxiliary device that vehicle ride comfort and safety are provided with, and wherein safety is its function of wanting most.When the manned vehicle rear portion was clashed into, occupant's head can move to the rear portion with inertia, at short notice, quickened all to be squeezed in fragile neck with the strength of slowing down, and the passive protection of at this moment resting the head on plays the effect of buffering energy-absorbing from face protection occupant's head and cervical vertebra.But because technological level restriction, domestic headrest stay uses the rod iron manufacturing, and its quality is big, and the weight of a pole is approximately 3 times of external pole with steel pipe manufacturing, and waste of material is bigger, and cost is higher.
Summary of the invention
Technical matters to be solved by this invention provides a kind of lightweight automotive headrest pole, and simple in structure, in light weight, strength of material is big, and materials are few, can reduce cost.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lightweight automotive headrest pole is provided; Comprise supporting part, connecting bridge and adjusting targeting part; Described adjusting targeting part is made up of two symmetrical steel pipes; The front end of described adjusting targeting part links to each other with connecting bridge; Described connecting bridge is made up of two symmetrical bended pipes and is linked to each other with two steel pipes regulating targeting part respectively, and described supporting part is a symmetrical U-shaped steel pipe, and two leg lower ends of described U-shaped steel pipe link to each other with the upper end of two steel pipes regulating targeting part respectively.
The steel pipe of described supporting part, connecting bridge and adjusting targeting part is the hollow low carbon steel pipe.
The angle of bend of the bended pipe of described connecting bridge be 90 the degree or near 90 the degree.
The steel pipe inboard on the right of described adjusting targeting part evenly has several regulating tanks along steel pipe.
The quantity of described regulating tank matches with adjusting targeting part steel pipe length.
Beneficial effect
The present invention relates to provide a kind of lightweight automotive headrest pole, the whole low carbon steel pipe that adopts, low carbon steel pipe is strengthened high, and anti-bending strength is good, than domestic solid pole loss of weight 70%, than external hollow bar loss of weight 20%.And supporting part is vertical with the seat torso line or near vertical; Make static weight or impact energy being fallen as much as possible by the connecting bridge material consumption; Reduce headrest stay and regulate the distortion of targeting part, can reduce the displacement of impact moment occupant's head, effectively protect occupant's head and cervical vertebra.

Fig. 3 is that the present invention installs and uses scheme drawing.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Shown in Fig. 1-3; Embodiment of the present invention relates to a kind of lightweight automotive headrest pole; Comprise supporting part 1, connecting bridge 2 and regulate targeting part 4; Described adjusting targeting part 4 is made up of two symmetrical steel pipes; The front end of described adjusting targeting part 4 links to each other with connecting bridge 2, and described connecting bridge 2 is made up of two symmetrical bended pipes and is linked to each other with two steel pipes regulating targeting part 4 respectively, and described supporting part 1 is a symmetrical U-shaped steel pipe; Two leg lower ends of described U-shaped steel pipe link to each other with the upper end of two steel pipes regulating targeting part 4 respectively; Described supporting part 1, connecting bridge 2 and the steel pipe of regulating targeting part 4 are the hollow low carbon steel pipe, and the angle of bend of the bended pipe of described connecting bridge 2 is 90 degree, and the steel pipe inboard on the right of described adjusting targeting part 4 evenly has 5 regulating tanks 3 along steel pipe.
Headrest stay is installed on the automotive headrest; Wherein supporting part 1, connecting bridge 2 are in headrest 5 inside; Regulate targeting part 4 and expose bottom at headrest; Described supporting part 1 be installed in and 5 the top of resting the head at a distance of the position of 65mm, the adjusting targeting part 4 of headrest stay is installed in the guide pin bushing of the chair back with the 6 parallel insertions of seat torso line, regulating tank 3 is stuck in headrest stay in the guide pin bushing of the chair back.
