Abstract

The invention discloses an automobile rearview mirror and relates to the technical field of automobile manufacturing. The automobile rearview mirror comprises a bracket provided with a rearview mirror, and an upper support and a lower support arranged on the bracket, wherein two ends of the bracket are arranged on a hinged shaft between the upper support and the lower support through a shaft hole; a wiring harness penetrates through the bracket; two joint surfaces of at least one connecting part are toothed surfaces which are meshed with each other; a spring for pressing the two joint surfaces is sleeved outside the hinged shaft in the toothed surfaces of the connecting part; and the spring is arranged between the lower support and a gasket. Compared with the prior art, the automobile rearview mirror has the advantages that the bracket can rotate relative to the upper support and the lower support and can be clamped through the toothed surfaces which are meshed with each other, and the angle is stably adjusted.

Description

Automobile rearview mirror

Technical field

The present invention relates to field of automobile, especially a kind of back mirror for the vehicle drive outdoor.

Background technology

Automobile rearview mirror is commonly called as side mirror, and it plays a part " second eye ", usually is divided into two kinds of exterior mirror and room mirrors.For outside rear-view mirror, general vehicle right and left both sides have, and its function mainly is to allow the situation of pedestrian, vehicle and other obstacles of driver's observation vehicle right and left both sides, guarantees driving or reversing safety.Inside rear-view mirror is mainly for the situation of driving the office worker and observing and watching attentively road surface behind passenger, article and the car, also has to prevent at night that the head lamp light of succeeding vehicle from causing and dazzle the eyes function.Chaufeur often needs according to the road conditions of travelling the back mirror angle of the outer both sides of car to be regulated, and conveniently finds better back visibibility, guarantees traffic safety.A kind of automobile rearview mirror is arranged, and the technical scheme of this automobile rearview mirror is: include the back mirror that is sleeved on the support, be coated with wire harness in the described support; The two ends of described support all are to be installed on the jointed shaft of upper bracket that automobile cab connects and undersetting by axis hole.In use there is following deficiency in this automobile rearview mirror technical scheme: because support and upper bracket and undersetting is hinged relative free, therefore, automobile is subject in the process of moving vibrating under the double action with wind and can often rotates, thereby can cause the direction change of back mirror, cause difficulty and inconvenience for the observation of chaufeur.In addition, back mirror also has electric heating function, when automobile when the weather such as rain, snow, mist travel, back mirror can by being embedded in the electric heating piece heating behind the eyeglass, guarantee that lens surface is clear; Pass in support owing to connecting the wire harness of electric heating piece, and walk around undersetting and penetrate operator's compartment and be connected with control module, between support and car door, have a bit of wire harness to expose, have potential safety hazard and not attractive in appearance.

Summary of the invention

Technical matters to be solved by this invention provides the comparatively stable automobile rearview mirror of a kind of adjusting angle.

In order to address the above problem, the technical solution used in the present invention is: this automobile rearview mirror comprises the support that back mirror is housed and upper bracket and the undersetting that described support is installed, and the two ends of described support all are to be installed on the jointed shaft of described upper bracket and described undersetting by axis hole; Be coated with wire harness in the described support, having two face of joints of a connecting portion at least is intermeshing toothed surface, be contained in jointed shaft in the described toothed surface of this connecting portion and be set with spring with the mutual crimping of two described face of joints outward, described spring places between described undersetting and the packing ring.

In the above-mentioned automobile rearview mirror technical scheme, technical scheme can also be more specifically: the tooth of two described toothed surface is 20 teeth, and angle is 18 degree between adjacent two teeth.

Further, establish the passage that installs described wire harness in the described undersetting.

Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:

1, support is rotatable with respect to upper and lower bearing, can be by intermeshing toothed surface screens, and adjusting angle is comparatively stable.

2, simple in structure, easy to operate.

3, because an end of support is installed in the undersetting, be contained in wire harness wire harness passage in undersetting in the support in the support and penetrate in the operator's compartment and be connected with control module, do not expose, eliminated potential safety hazard and more attractive in appearance.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing embodiment:

Fig. 1, automobile rearview mirror shown in Figure 2 comprise support 2 that back mirror 1 is housed and upper bracket 9 and the undersetting 4 of mounting bracket 2, the two ends of support 2 all are to be installed on the jointed shaft 8 of upper bracket 9 and undersetting 4 by axis hole, it is intermeshing toothed surface that two face of joints of a connecting portion are arranged in the present embodiment, the lower surface 3-1 that a face of joint of connecting portion is Support joint 3, another face of joint of connecting portion is the upper surface 4-1 of undersetting 4; The tooth of the lower surface 3-1 of Support joint 3 and the upper surface 4-1 of undersetting 4 is 20 teeth, and the angle of adjacent two teeth is 18 degree; Such as Fig. 3, Fig. 4 and shown in Figure 5.Be contained in the jointed shaft 8 outer springs 5 that are set with two mutual crimping of face of joint in this connecting portion toothed surface, spring 5 places between undersetting 4 and the packing ring 6.Jointed shaft 8 installed successively Support joint 3, undersetting 4, spring 5, packing ring 6 and is connected with nut to connect Support joint 3 is hinged on the undersetting 4.Be coated with wire harness in the support 2, establish the passage that installs wire harness in the undersetting 4, be contained in wire harness in the support 2 and pass in the support 2 to penetrate in the operator's compartment through the wire harness passages in the undersetting 4 and be connected with control module, do not expose, eliminated potential safety hazard and more attractive in appearance.

When upwards mentioning Support joint 3, drive upwards Compress Spring 5 of jointed shaft 8, packing ring 6, Support joint 3 separates with undersetting 4 intermeshing toothed surface, Support joint 3 is rotatable with respect to undersetting 4, but the angle of adjusting rearview mirror 1, and every adjusting one tooth turns 18 degree, after back mirror 1 is adjusted to suitable position, put down Support joint 3, under the effect of spring 5 power, intermeshing can the location of toothed surface of Support joint 3 and bearing 4.
