Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 3 and 4, an angle sensor holder 100 includes a base 110, a top 120, and a rotating member 130. The top base 120 is disposed opposite to the bottom base 110, and the bottom base 110 includes a body portion 111 and a transmission shaft 112 protruding from the body portion 111 toward the top base 120, and an end of the transmission shaft 112 is connected to an angle sensor (not shown). The rotation member 130 is connected to the top base 120 and the transmission shaft 112, respectively, so that the base 110 is rotatable relative to the top base 120.

Specifically, when the angle sensor fixing base 100 with the above structure is applied, the base 110 can be installed on a front axle of a tractor or other vehicle type, and the base 110 is connected with left and right steering knuckles of the front axle, so that when a tractor steering wheel rotates left and right, the left and right steering knuckles are pushed by hydraulic pressure to rotate left and right, the rotating angle displacement is transmitted to the angle sensor through a transmission shaft 112 of the base 110, the angle sensor converts a physical angle displacement signal into an electric signal, and the electric signal transmits the signal to a central control unit through a data line, thereby completing steering data acquisition of a tractor vehicle in automatic navigation driving.

In the fixing base 100 of the present embodiment, the base 110 includes a main body 111 and a transmission shaft 112 protruding from the main body 111 to the top base 120, an end of the transmission shaft 112 is connected to the angle sensor, and the rotating member 130 is connected to the top base 120 and the transmission shaft 112 respectively.

Obviously, the fixing base 100 of this embodiment, its base 110 can directly be connected with the front axle and the angle sensor of tractor etc. respectively, realize directly transmitting the rotation angle displacement volume of tractor etc. to angle sensor via base 110, not only can effectively simplify the structure of fixing base 100, realize angle sensor's portable installation, but also can effectively improve angle sensor's measurement accuracy, simultaneously, still effectively solved the not enough problem of fixing base spatial position, action space is not enough and the part is fragile among the background art.

As shown in fig. 3 and 4, the top chassis 120 is provided with a mounting hole 121 penetrating the thickness thereof and a mounting groove 122 recessed from the mounting hole 121 in a direction away from the center of the top chassis 120. The rotating member 130 is disposed around the outer circumferential wall of the transmission shaft 112 and rotatably disposed in the mounting groove 122.

It should be noted that, no particular limitation is imposed on the specific structure of the rotating element 130, for example, the rotating element 130 may be in the form of a bearing, for example, a rolling bearing, etc., and obviously, when the bearing structure is adopted, the top seat 120 is a bearing seat. Of course, besides the bearing structure, other rotating structures can be selected by those skilled in the art according to actual needs.

As shown in fig. 3 and 4, in order to limit the axial displacement of the rotating element 130, the fixing base 100 further includes a pressing plate 140, the pressing plate 140 is located on a side of the rotating element 130 facing the base 110, and the pressing plate 140 is connected to the rotating element 130 and the top base 120 respectively, for example, as shown in fig. 4, the pressing plate 140 may be connected to the top base 120 by a fastening element 150 (e.g., a screw, etc.), but the pressing plate 140 may also be connected to the top base 120 by some other connection means, which is not limited in this respect.

As shown in fig. 3 and 4, in order to further limit the axial displacement of the rotating member 130, the fixing base 100 further includes a snap member 160, and the snap member 160 may have a ring-shaped structure. One side of the top base 120 departing from the base 110 is provided with a slot (not shown), the outer side wall of the clamping member 160 is clamped in the slot, and the inner side wall of the clamping member 160 abuts against the rotating member 130. In this way, the rotation member 130 can be restricted from moving upward in the axial direction by the engagement member 160, and the rotation member 130 can be restricted from moving downward in the axial direction by the pressing plate 140, so that the installation position of the rotation member 130 can be ensured to be accurate and can only rotate.

In order to make the fixing base suitable for the severe working environment or the environment with much mud and dust, as shown in fig. 3 and 4, the fixing base 100 further includes a dust-proof member 170. The dust-proof member 170 is interposed between the main body 111 and the top holder 120. In this way, with the aid of the dust-proof component 170, a fully-enclosed dust-proof design of the fixing base 100 can be realized, and the fully-enclosed dust-proof design can avoid the clamping failure between the connecting shaft 112 and the rotating component 130 caused by the influence of dust, thereby effectively protecting the data acquisition work of the automatic navigation system.

It should be noted that, the specific structure of the dust-proof member 170 is not particularly limited, and specifically, for example, the dust-proof member 170 may adopt a dust-proof structure such as a dust-proof rubber ring.

As shown in fig. 3 and 4, in order to facilitate mounting the fixing base 100 to a front axle of a tractor or the like, the body 111 is provided with at least one mounting hole 111a penetrating through a thickness thereof, and the body 111 is connected to a mounting bracket (not shown in the drawings) through the mounting hole 111 a.

Specifically, as shown in fig. 3, the body portion 111 may be provided with three mounting holes 111a, and the three mounting holes 111a may be arranged at equal intervals in the circumferential direction of the body portion 111. Of course, besides, those skilled in the art can design a larger number of mounting holes 111a, which is determined according to actual needs.

It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
