[0021] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application (for the convenience of description and understanding, hereinafter Figure 1Above (the above is described). All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

[0022] Please refer to Figures 1-9 , this application provides a technical solution: a housing structure for an angle sensor, including an outer lower cover 1. A connection hole is provided at the bottom of the outer lower cover 1. An outer shell 2 is concentrically arranged with the outer lower cover 1. Fixed holes corresponding to the outer lower cover 1 are provided on the outer shell 2.

[0023] The outer lower cover 1 is the basic structure of the entire sensor, providing a stable installation platform. The outer shell 2 provides additional structural support and protection, and together with the outer lower cover 1 constitutes a complete sensor housing. The two are coaxially arranged, and there are fixed holes on the outer shell 2 corresponding to the connection holes on the outer lower cover 1, improving the convenience of assembly and the assembly efficiency.

[0024] An inner cover 4 is sleeved on the annular protrusion in the middle of the outer lower cover 1. A rotating cover 3 is arranged on the outer side of the inner cover 4. The protruding part at the upper end of the rotating cover 3 passes through the through hole above the outer shell 2.

[0025] The inner cover 4 is a fixed reference point for installing the core detection element of the angle sensor housing structure. The inner cover 4 provides a fixed reference point for the rotating cover 3.

[0026] At the contact part between the inner cover 4 and the outer shell 2, the protrusion of the outer shell 2 is snapped into the groove of the inner cover 4 to ensure that the two can be tightly combined together and ensure the stability of use.

[0027] The rotating cover 3 can rotate freely relative to the inner cover 4. Its rotation angle is measured by the sensor element in the inner cover 4. It has a protruding part at its upper end, which passes through the through hole above the outer shell 2 and interacts with the inner cover 4 and the sensor element.

[0028] Furthermore, concentric outer open ring walls are provided on the outer side of the outer lower cover 1, and semi-circular arc grooves are provided between the outer open ring walls.

[0029] The outer open ring walls of the outer lower cover 1 play a role in reinforcement on the one hand, increasing the structural strength of the outer lower cover 1. On the other hand, the shape and position of the semi-circular arc grooves are set corresponding to the semi-circular arc grooves and fixed blocks in the outer shell 2 to help ensure the correct alignment of the sensor.

[0030] The upper end of the outer open ring wall of the outer lower cover 1 extends outward and is inclined towards the center of the outer lower cover 1, while the lower edge of the outer shell 2 is inclined outward, and the two are snapped together.

[0031] Furthermore, support seats are provided on the upper surface of the outer lower cover 1, and the support seats are located on both sides of the semi-circular arc grooves.

[0032] The support base can provide support. Especially when the rotating cover 3 rotates, the support base can help maintain the smooth operation of the rotating cover 3, reduce shaking. The support base also has a certain positioning function to ensure that the rotating cover 3 can be accurately aligned during rotation.

[0033] Furthermore, a semi-circular arc groove is also provided on the outer shell 2, and the semi-circular arc groove on the outer shell 2 is correspondingly arranged with the semi-circular arc groove on the outer lower cover 1.

[0034] Furthermore, the outer shell 2 is also provided with a fixing block corresponding to the notch on the outer lower cover 1.

[0035] The cooperation between the fixing block and the notch on the outer lower cover 1 can ensure the correct alignment and firm fixation of the outer shell 2 and the outer lower cover 1 together; through the cooperation between the fixing block and the notch, the installation position of the entire sensor can be ensured to be accurate; the fixing block can enhance the connection strength between the outer shell 2 and the outer lower cover 1 and improve the structural stability of the entire sensor.

[0036] During use: Fix the outer lower cover 1 at the required position through the connection holes at its bottom, such as on a robotic arm or any component that needs to measure the rotation angle. Use the semi-circular arc groove on the outer lower cover 1 as a reference mark to ensure the correct alignment of the sensor. Sleeve the inner cover 4 onto the annular protrusion in the middle of the outer lower cover 1. Pass the upper protrusion of the rotating cover 3 through the through hole above the outer shell 2, and connect the outer shell 2 and the outer lower cover 1 through the fixing holes. During this process, the fixing block on the outer shell 2 needs to be aligned with the notch on the outer lower cover 1 to ensure the correct installation of the outer shell 2. Connect the rotating cover 3 to the mechanical component that needs to measure the angle change.

[0037] When the external mechanical component rotates, it will drive the rotating cover 3 to rotate together. The rotation angle of the rotating cover 3 is measured by the sensor element in the inner cover 4 and converted into an electrical signal for output. During rotation, the support base ensures the smooth operation of the rotating cover 3, reduces unnecessary vibrations, and at the same time ensures that the rotating cover 3 can be accurately aligned during rotation.

[0038] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
