[0048] like Figures 1-6 As shown, according to a first aspect of the embodiments of this application, a head shell is provided, including a shell 1, a first side plate assembly 2, and a second side plate assembly 3; the first end and the second end of the shell 1 are connected to form an annular structure, the annular structure having a continuous outer surface 18, and a first opening 13 and a second opening 14 are formed on both sides of the axial direction of the shell 1; the first side plate assembly 2 is disposed in the first opening 13, the second side plate assembly 3 is disposed in the second opening 14, and the first side plate assembly 2, the second side plate assembly 3, and the inner surface 19 of the shell 1 form a receiving cavity 15; a first clearance hole 6 is formed between the first side plate assembly 2 and the shell 1, the first clearance hole 6 communicating with the receiving cavity 15, and the first clearance hole 6 is used for a component located in the receiving cavity 15 to pass through to the outside of the shell 1; a second clearance hole 7 is formed between the second side plate assembly 3 and the shell 1, the second clearance hole 7 communicating with the receiving cavity 15, and the second clearance hole 7 is used for a component located in the receiving cavity 15 to pass through to the outside of the shell 1.

[0049] like Figures 1-5As shown, the head shell includes a shell 1, a first side plate assembly 2, and a second side plate assembly 3; wherein, the shell 1 forms an annular structure, and a first opening 13 and a second opening 14 are formed on both sides of the axial direction of the shell 1, that is, on both sides of the annular structure. The shell 1 has a continuous outer surface 18, which means that there are no through holes on the outer wall of the shell 1 in the axial direction.

[0050] To further explain, the first side plate assembly 2 is connected to the housing 1 at the first opening 13, and the second side plate assembly 3 is connected to the housing 1 at the second opening 14. The first side plate assembly 2, the second side plate assembly 3, and the interior of the housing 1 form a receiving cavity 15. The first side plate assembly 2 is connected to the housing 1 at the first opening 13 and forms a first clearance hole 6. The second side plate assembly 3 is connected to the housing 1 at the second opening 14 and forms a second clearance hole 7. The first clearance hole 6 communicates with the receiving cavity 15, and the second clearance hole 7 communicates with the receiving cavity 15. Since the first opening 13 and the second opening 14 are located on both sides of the axial direction of the housing 1, the first clearance hole 6 and the second clearance hole 7 are also located on both sides of the housing 1.

[0051] To further explain, since some functional components of the head mechanism are provided in the receiving cavity 15, the first clearance hole 6 and the second clearance hole 7 are used to allow the components located in the receiving cavity 15 to pass through to the outside of the housing 1.

[0052] The head shell of this application has a continuous outer surface 18 of the shell 1, and the first clearance hole 6 and the second clearance hole 7 are opened on both sides of the shell 1. On the one hand, it can reduce the structural complexity of the shell 1 and reduce the installation difficulty of the shell 1. On the other hand, it can improve the structural strength of the shell 1, thereby providing protection for the components set in the receiving cavity 11.

[0053] The radial cross-section of the shell 1 can be circular, elliptical, rectangular, square, or other irregular shapes.

[0054] Wherein, the first end of the shell 1 refers to the first edge 111, and the second end of the shell 1 refers to the second edge 121.

[0055] like Figure 4 and Figure 5As shown, in an optional embodiment, the head shell further includes a first decorative element 4 and a second decorative element 5; the first decorative element 4 has a first clearance groove 41, the first decorative element 4 is located in the receiving cavity 15, the first decorative element 4 rotates in the receiving cavity 15 along the circumference of the shell 1, and the first clearance groove 41 connects the receiving cavity 15 and the first clearance hole 6; specifically, the first decorative element 4 is disposed in the receiving cavity 15, the first decorative element 4 can cover the first clearance hole 6, the first decorative element 4 has a first clearance groove 41, the first clearance groove 41 connects the first clearance hole 6 and the receiving cavity 15, the first decorative element 4 can rotate in the receiving cavity 15 along the circumference of the shell 1, and the size of the first clearance groove 41 along the circumference of the shell 1 is smaller than the size of the first clearance hole 6; in this embodiment This formula is applicable to components that need to rotate relative to the housing 1 and are housed within the receiving cavity 15. For example, a portion of the first bracket is located within the receiving cavity 15, and another portion of the first bracket extends to the outside of the housing 1 through the first clearance groove 41. The first bracket is connected to the first decorative piece 4. When the housing 1 rotates relative to it, the first bracket and the first decorative piece 4 rotate together. The first decorative piece 4 rotates circumferentially relative to the housing 1, and a portion of the first bracket and the first decorative piece 4 also rotate relative to the first clearance hole 6. The first clearance hole 6 restricts the rotation range of the first bracket. In this case, since the first bracket needs to have a certain rotation range relative to the housing 1, the first decorative piece 4 is provided to ensure the rotation of the first bracket while reducing the communication space between the receiving cavity 15 and the outside of the housing 1, so as to prevent external impurities from entering the receiving cavity 15.

[0056] The second decorative element 5 has a second clearance groove 51. The second decorative element 5 is located in the receiving cavity 15 and can rotate around the circumference of the housing 1. The second clearance groove 51 connects the receiving cavity 15 and the second clearance hole 7. Specifically, the second decorative element 5 is disposed in the receiving cavity 15 and can cover the second clearance hole 7. The second decorative element 5 has a second clearance groove 51 that connects the second clearance hole 7 and the receiving cavity 15. The second decorative element 5 can rotate around the circumference of the housing 1 within the receiving cavity 15. The size of the second clearance groove 51 is smaller than the size of the second clearance hole 7 around the circumference of the housing 1. In this embodiment, it is suitable for situations where a necessary decoration needs to be placed in the receiving cavity 15. For example, a portion of the second bracket is located inside the receiving cavity 15, and another portion of the second bracket extends to the outside of the housing 1 through the second clearance groove 51. The second bracket is connected to the second decorative piece 5. When the housing 1 rotates relative to it, the second bracket and the second decorative piece 5 rotate together. The second decorative piece 5 rotates circumferentially relative to the housing 1. A portion of the second bracket and the second decorative piece 5 also rotate relative to the second clearance hole 7. The second clearance hole 7 restricts the rotation range of the second bracket. In this case, since the second bracket needs to have a certain rotation range relative to the housing 1, the second decorative piece 5 is provided to reduce the communication space between the receiving cavity 15 and the outside of the housing 1 while ensuring the rotation of the second bracket, so as to prevent external impurities from entering the receiving cavity 15.

[0057] like Figure 3As shown, in an optional embodiment, the housing 1 includes a first sub-housing 11 and a second sub-housing 12. The first sub-housing 11 includes a first edge 111 facing forward and having a protrusion 112. The second sub-housing 12 includes a second edge 121 facing rearward and having a groove 122. The first edge 111 abuts against the second edge 121, and the protrusion 112 is embedded in the groove 122. Specifically, the first sub-housing 11 and the second sub-housing 12 are connected to form the housing 1. The first sub-housing 11 includes a first edge 111. The length direction of the housing 1 is the axial direction of the housing 1, and a protrusion 112 is formed on the first edge 111; the second sub-housing 12 includes a second edge 121, the length direction of the second edge 121 is the axial direction of the housing 1, and a groove 122 is formed on the second edge 121. The first sub-housing 11 and the second sub-housing 12 are connected, the first edge 111 and the second edge 121 abut against each other, and the protrusion 112 is embedded in the groove 122. In this embodiment, the protrusion 112 is embedded in the groove 122, and the groove 122 can restrict the axial movement of the protrusion 112 in the housing 1. That is to say, the second sub-housing 12 will restrict the axial movement of the first sub-housing 11 in the housing 1, thereby improving the structural stability of the housing 1.

[0058] To further explain, the first edge 111 faces forward and the second edge 121 faces backward. That is to say, the first sub-shell 11 and the second sub-shell 12 are connected in the front-back direction. The connection point of the first edge 111 and the second edge 121 is located at the top of the shell 1. When installing a camera module or display screen inside the shell 1, the connection point can be avoided, thereby improving the user experience.

[0059] like Figure 2 ,like Figure 4 and Figure 5As shown, in an optional embodiment, the second sub-shell 12 further includes a third edge 123 and a fourth edge 124 arranged opposite to each other. The third edge 123 is angularly connected to the second edge 121, and the fourth edge 124 is angularly connected to the second edge 121. The third edge 123 has a first notch 125, and the fourth edge 124 has a second notch 126. Specifically, the third edge 123 and the fourth edge 124 are located on opposite sides of the axial direction of the second sub-shell 12, and the third edge 123 is angularly connected to the second edge 121. The fourth edge 124 is connected to the second edge 121 at an angle. That is, the third edge 123 and the second edge 121 have different orientations. The fourth edge 124 and the second edge 121 have different orientations. The third edge 123 has a first notch 125, which extends along the axial direction of the housing 1 towards the fourth edge 124. The fourth edge 124 has a second notch 126, which extends along the axial direction of the housing 1 towards the third edge 123. The third edge 123 is located at the first opening 13, and the fourth edge 124 is located at the second opening 14.

[0060] To further explain, the first side plate assembly 2 and the first notch 125 form the first clearance hole 6. The first side plate assembly 2 is located at the first opening 13. Since the first notch 125 is formed at the third edge 123, the first side plate assembly 2 and the first notch 125 also form the first clearance hole 6. The second side plate assembly 3 and the second notch 126 form the second clearance hole 7. The second side plate assembly 3 is located at the second opening 14. Since the second notch 126 is formed at the fourth edge 124, the second side plate assembly 3 and the second notch 126 also form the second clearance hole 7. In this embodiment, the first clearance hole 6 extends along the axial direction of the housing 1, and the second clearance hole 7 also extends along the axial direction of the housing 1, thereby facilitating the components located in the receiving cavity 15 to pass through the first clearance hole 6 and the second clearance hole 7 to the outside of the housing 1.

[0061] In one specific embodiment, the inner surface 19 of the first sub-shell 11 is provided with at least one first limiting member 114, the first limiting member 114 protruding from the first edge 111, and the inner surface 19 of the second sub-shell 12 abutting against the first limiting member 114.

[0062] In another specific embodiment, the first sub-shell 11 further includes a fifth edge 116, which is arranged opposite to the first edge 111. The inner surface 19 of the first sub-shell 11 is provided with at least one second limiting member 115, which protrudes from the fifth edge 116. The inner surface 19 of the second sub-shell 12 abuts against the second limiting member 115.

[0063] like Figure 3 and Figure 4 As shown, in another specific embodiment, the inner surface 19 of the first sub-shell 11 is provided with at least one first limiting member 114, the first limiting member 114 protruding from the first edge 111, and the inner surface 19 of the second sub-shell 12 abuts against the first limiting member 114; the first sub-shell 11 further includes a fifth edge 116, the fifth edge 116 being arranged opposite to the first edge 111, and the inner surface 19 of the first sub-shell 11 is provided with at least one second limiting member 115, the second limiting member 115 protruding from the first edge 111. The fifth edge 116 is mentioned, and the inner surface 19 of the second sub-shell 12 abuts against the second limiting member 115; taking this embodiment as an example, the first limiting member 114 is disposed on the inner surface 19 of the first sub-shell 11. The first limiting member 114 protrudes beyond the first edge 111 but does not protrude beyond the outer surface 18 of the first sub-shell 11. The first sub-shell 11 is connected to the second sub-shell 12, the first edge 111 abuts against the second edge 121, and the first limiting member 114 abuts against the inner surface 19 of the second sub-shell 12 to restrict the second sub-shell 12 from moving. For the radial movement of the first sub-shell 11, the first sub-shell 11 further includes a fifth edge 116, which is arranged radially opposite to the first edge 111 along the shell 1. The second sub-shell 12 further includes a sixth edge 127, which is arranged radially opposite to the second edge 121 along the shell 1. The inner surface 19 of the first sub-shell 11 is also provided with a second limiting member 115, which protrudes beyond the fifth edge 116 but does not protrude beyond the outer surface 18 of the first sub-shell 11. The second sub-shell 12 is connected to the first sub-shell 11. The fifth edge 116 abuts against the sixth edge 127, and the inner surface 19 of the second sub-shell 12 abuts against the second limiting member 115. In this embodiment, the first limiting member 114 and the second limiting member 115 work together to restrict the radial movement of the second sub-shell 12 relative to the first sub-shell 11 along the shell 1, thereby improving the structural stability of the shell 1. When the first sub-shell 11 and the second sub-shell 12 are installed, the first limiting member 114 and the second limiting member 115 can also play a role in installation positioning, thereby improving installation efficiency and reducing installation difficulty.

[0064] In one alternative embodiment, the first sub-housing 11 and the second sub-housing 12 are detachably connected; specifically, the first sub-housing 11 and the second sub-housing 12 can be connected by snap-fit ​​or screws; the detachable connection of the first sub-housing 11 and the second sub-housing 12 facilitates the maintenance and repair of the components disposed within the receiving cavity 15.

[0067] In another specific embodiment, the first sub-shell 11 has a first through hole 113, which communicates with the receiving cavity 15; the second sub-shell 12 has at least one second through hole, which communicates with the receiving cavity 15; in this embodiment, the receiving cavity 15 may be provided with at least two camera modules, one of which collects environmental information of the outside of the shell 1 through the first through hole 113, and the other camera module collects environmental information of the outside of the shell 1 through the second through hole.

[0068] The first through hole and the second through hole are both opened along the radial direction of the shell. That is, the axial direction of the first through hole 113 is the same as the radial direction of the shell 1, and the axial direction of the second through hole is the same as the radial direction of the shell 1.

[0069] In another specific embodiment, both the first sub-shell 11 and the second sub-shell 12 are made of transparent material.
