Abstract

A collision preventing reset device for an automobile aerial is composed of a base (1), gravity rotation bodies (2) and a protecting bar (3). The base can be installed on an automobile body, the gravity rotation bodies (2) are installed in axel holes (12) of two wings (11) of the base (1) through a rotation shaft (21) and can freely rotate around the rotation shaft, an aerial terminal (27) and the protecting bar (3) are installed on the gravity rotation bodies (2), and thus the aerial (4) can be protected from direct collision with obstacles, and can naturally fall down when collision occurs to avoid broken-down and damage. The aerial can automatically reset depending on the gravity after the automobile passes the obstacle.

Description

Collision preventing reset device for automobile aerial

The utility model relates to the car antenna device, further is the antenna anticollision device, collision-prevention device.

Equipment such as broadcast receiver, sound equipment, handheld wireless phone are housed on the Hyundai Motor usually, equipment such as television set also are housed in senior railway carriage or compartment car.The application of these equipment all rely on be loaded on car outer accept the antenna acknowledge(ment) signal, yet take a broad view of existing car antenna all is directly to be installed in unshielded device on the vehicle body, therefore, barriers such as Chang Yin and branch, signboard, overline bridge collide and the destruction that fractures, for the car owner causes very big loss.

The utility model is at above-mentioned situation, take the lead in initiating out a kind of anticollision device, collision-prevention device that can prevent that car antenna from being broken by barrier, this device can prevent that not only car antenna from being broken, and antenna can be automatically reset after being hit, and remains vertical position.

The utility model design principle is to divide into a base that can rely on from repeats bits at antenna, and stretches out an antenna fender rod to prevent the direct and barrier thing bump of antenna on this end.

Details are as follows in conjunction with the accompanying drawings for the utility model, wherein:

Fig. 1 is the crashproof automatic reset device schematic diagram of car antenna;

Fig. 2 is crashproof automatic reset device exploded view;

Fig. 3 is crashproof automatic reset device end view;

Fig. 4 is toppled over schematic diagram for antenna hits.

As Fig. 1,2,3, shown in, the crashproof automatic reset device of the design's car antenna is turned (2) by base (1), gravity and guard bar (3) is formed.Base (1) is a notch plate, a location hole (14) is arranged on the base plate (10), the upper limb of both wings (11) respectively has an axis hole (12) that bearing (13) are housed, base plate (10) can be installed on the position of vehicle body setting, also can be provided with at the lower edge of base plate (10) to make easier for installation for the connecting plate that has bolt (16) (15) that is installed on the vehicle body.Gravity (2) bottom of turning is a spheroid, and a telescopic ball (23) is established in the spheroid bottom, and location hole (14) coupling of this ball (23) and base plate (10) is to keep the vertical position of antenna.The turn upper end of (2) of gravity is bottleneck shape (202), and has two rotating shafts (21) can be installed in the axis hole (12) of base, and can freely rotate around axle.Gravity (2) upper end of turning also is provided with platform (25), antenna terminal (27) is housed with fix up an aerial wire (4) on the platform (25), have aperture (251) in addition, the turn aperture (203) of (2) bottleneck upper end of this aperture (251) and gravity is in a upright position, inserts for antenna guard bar (3).

The above-mentioned gravity available various suitable methods of lowermost end ball (23) of turning are installed, and the utility model proposes a mode as shown in Figure 2, and promptly the turn main body of (2) of gravity is a gravity ball core (20) that constant weight is arranged; An aperture (201) is arranged at its bottom, spring (22) and spin (23) are arranged in the aperture, a following dome (24) that has an aperture (241) is installed in the bottom of gravity ball core (20), make spin (23) can partly pass aperture (241), be embedded in the location hole (14) on the base plate (10), (2) under normal circumstances are in vertical position so that gravity is turned, and when being subjected to clashing into, ball (23) breaks away from location hole (14), rotates freely.

According to above-mentioned design as seen by Fig. 1 and Fig. 4, the position of antenna guard bar (3) is in the front side of antenna (4), under normal circumstances ball (23) is embedded in the aperture (14) on the base plate (10), make antenna keep vertical position, but when when driving, running into barrier, guard bar (2) bumps against with barrier, the power of hitting makes ball (23) leave aperture (14), because rotating shaft (21) can freely be rotated in axis hole (12), whole device is toppled over (see figure 4) backward, and antenna is avoided directly and the barrier collision.After automobile crossed barrier, because the effect of gravity ball core (20) resets whole device, ball this moment (23) inlay card was once more gone into aperture (14), and antenna (4) still remains on upright position as shown in Figure 1.

Therefore simple installation of the present utility model; as long as utilize the connection seat board (15) of base (10) bolt (16) to be installed in the automobile desired location; just can install whole device appropriate; and can not influence the outward appearance of automobile so the design's the crashproof automatic reset device of car antenna not only can protect antenna not to be damaged effectively; and cost is cheap; easy for installation, for various wireless messages instruments in the automobile provide one perfect umbrella.
