[0031] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. Below, reference is made to Figures 1 - 3 Describe the mounting assembly 100 for the to-be-fixed component 200 according to the embodiment of the first aspect of the present invention.

[0032] As Figure 1 Figure 2 and Figure 8 shown, the mounting assembly 100 for the to-be-fixed component 200 according to the embodiment of the first aspect of the present invention includes a housing 1 and a locking structure 2.

[0033] Specifically, the locking structure 2 is provided on the housing 1, a rotating member 22 is provided on the housing 1, and the rotating member 22 is connected to a locking block 21. The rotation of the rotating member 22 drives the locking block 21 to be rotatable between an unlocking position and a locking position. When the locking block 21 is in the unlocking position, the to-be-fixed component 200 is adapted to be separated from the locking block 21; when the locking block 21 is in the locking position, the to-be-fixed component 200 is adapted to cooperate with the locking block 21 to be locked within the housing 1.

[0034] For example, in the examples of , Figure 1 and Figure 2 , the to-be-fixed component 200 is placed within the housing 1. The rotating member 22 extends in the front-rear direction. By rotating the rotating member 22, the locking block 21 is driven to move between the unlocking position and the locking position. When the locking block 21 is in the unlocking position, the locking block 21 is separated from the to-be-fixed component 200, that is, the to-be-fixed component 200 can be taken out from the housing 1, separating the to-be-fixed component 200 from the housing 1. When the locking block 21 is in the locking position (such as the position shown in Figure  8 ), the locking block 21 contacts the to-be-fixed component 200, locking the to-be-fixed component 200 within the housing 1, that is, fixing the to-be-fixed component 200 within the housing 1.

[0035] With such a setting, through the setting of the locking structure 2, the mounting assembly 100 and the to-be-fixed member 200 can be disassembled and separated, that is, the to-be-fixed member 200 can be taken out and used alone, or the to-be-fixed member 200 can be installed on the electrical equipment 300 through the mounting assembly 100 for use, which is convenient for flexible use according to the actual use situation and improves the convenience of use. Moreover, through the mounting assembly 100, the to-be-fixed member 200 can also be installed on different electrical equipment 300, improving the applicability of the to-be-fixed member 200 in use and the matching degree of use. In addition, by driving the locking block 21 to rotate through the rotating member 22, the separation and installation of the mounting assembly 100 and the to-be-fixed member 200 are realized. Fixed in a mechanical manner, the operation is simple, convenient for disassembly and installation, and the mechanical operation does not require waiting, thus effectively improving the operation efficiency. Moreover, the structure of the locking structure 2 is simple and easy to process, thus improving the production efficiency of the locking structure 2. In addition, the structure of the mounting assembly 100 is small and occupies a small space, so that the to-be-fixed member 200 can occupy a larger space. When the to-be-fixed member 200 is a speaker, the low frequency is improved.

[0036] Combined Figure 5 、 Figure 1 and Figure 8 , a through hole 11 is formed in the housing 1, and the locking block 21 is arranged at the through hole 11. For example, in the examples of Figure 9 Figure 1 and Figure 8 , the through hole 11 penetrates through the side wall of the housing 1, and the rotating member 22 drives the locking block 21 to rotate in the through hole 11. With such a setting, the cooperation mode of the locking structure 2 and the housing 1 is simple, convenient for installation, improving the assembly efficiency and the reliability of use. In addition, the through hole 11 also facilitates the movement of the locking block 21 between the unlocking position and the locking position, improving the convenience of use.

[0037] According to the mounting assembly 100 for the to-be-fixed member 200 of the present invention, through the locking structure 2, the to-be-fixed member 200 and the mounting assembly 100 can be separated and cooperated, and the to-be-fixed member 200 can also be installed on different electrical equipment 300 through the mounting assembly 100 for use, which is convenient for flexible setting according to the actual use situation and improves the convenience and matching degree of use. In addition, by rotating the rotating member 22 to realize the separation and installation of the locking block 21 and the to-be-fixed member 200, it is a mechanical operation, the operation is simple, convenient for disassembly and separation, and the operation efficiency is improved.

[0038] According to some embodiments of the present invention, with reference to Figure 9 、 Figure 1 and Figure 2, the locking block 21 has a connected first side surface 211 and a second side surface 212. When the locking block 21 is in the unlocking position, the first side surface 211 is adapted to face the to-be-fixed member 200, and there is a gap between the first side surface 211 and the to-be-fixed member 200. When the locking block 21 is in the locking position, the second side surface 212 is adapted to have an interference fit with the outer peripheral surface of the to-be-fixed member 200.

[0039] For example, in Figure 5 , Figure 1 and Figure 2 's examples, the first side surface 211 and the second side surface 212 are located on the outer side of the circumferential direction of the locking block 21, and the outer peripheral side of the locking block 21 has elasticity. With such a setting, when the locking block 21 is in the unlocking position, the first side surface 211 is not in contact with the to-be-fixed member 200, enabling the to-be-fixed member 200 to be separable from the housing 1, facilitating the removal of the to-be-fixed member 200 from the housing 1. When the locking block 21 is in the locking position, the second side surface 212 has an interference fit with the to-be-fixed member 200, fixing the to-be-fixed member 200 in a direction perpendicular to the front-rear direction (such as in Figure 5 's example, fixing the to-be-fixed member 200 in the up-down direction), improving the installation stability of the to-be-fixed member 200 and the housing 1, and thus improving the use stability of the to-be-fixed member 200.

[0040] According to some embodiments of the present invention, referring to Figure 5 , in the first direction (such as the left-right direction shown in Figure 2 ), the distance between the outer peripheral surface of the rotating member 22 and the first side surface 211 is L1, and in the second direction (such as the up-down direction shown in Figure 2 ), the distance between the outer peripheral surface of the rotating member 22 and the second side surface 212 is L2, and L1 and L2 satisfy: 0.7 ≤ L1 / L2 ≤ 0.9, and the first direction, the second direction, and the axial direction of the rotating member 22 are orthogonal.

[0041] For example, in Figure 2In the example, the maximum distance between the outer peripheral surface of the rotating member 22 and the first side surface 211 in the left-right direction is L1, and the distance between the second side surface 212 and the outer peripheral surface of the rotating member 22 is greater than the distance between the first side surface 211 and the outer peripheral surface of the rotating member 22. When the ratio of L1 to L2 is less than 0.7, the distance between the outer peripheral surface of the rotating member 22 and the second side surface 212 in the up-down direction is relatively large, and the degree of interference fit between the second side surface 212 and the outer peripheral surface of the to-be-fixed member 200 is relatively large. When the second side surface 212 is in a compressed state for a long time, it is prone to fatigue, which is not convenient for subsequent use. When the ratio of L1 to L2 is greater than 0.9, L1 is relatively large, the distance between the first side surface 211 and the to-be-fixed member 200 is relatively small, which is not convenient for separating the to-be-fixed member 200 from the housing 1, or L2 is relatively small, and the degree of interference fit between the second side surface 212 and the outer peripheral surface of the to-be-fixed member 200 is relatively small, reducing the installation stability of the to-be-fixed member 200 and the housing 1, thereby reducing the use stability of the to-be-fixed member 200. Therefore, by setting L1 and L2 to satisfy: 0.7 ≤ L1 / L2 ≤ 0.9, L1 and L2 are reasonably set, reducing the fatigue state of the second side surface 212 after long-term use, thereby prolonging the service life of the second side surface 212. In addition, the strength of the fit between the second side surface 212 and the to-be-fixed member 200 is improved, thereby improving the use stability of the to-be-fixed member 200. In addition, when the locking structure 2 is in the unlocking position, it is convenient for the to-be-fixed member 200 to be separated from the housing 1. Among them, the locking structure 2 is an overall silicone part or a Teflon part, or the inside of the locking structure 2 is a metal part or a plastic part, and the outside of the locking structure 2 is a silicone part or a Teflon part, that is, the silicone part or the Teflon part wraps the metal part or the plastic part.

[0042] According to some embodiments of the present invention, with reference to Figure 2, the piece to be fixed 200 includes a housing 201 of the piece to be fixed, the thickness of the housing 201 of the piece to be fixed is d1, and the interference amount between the second side surface 212 and the piece to be fixed 200 is Y1. Among them, d1 and Y1 satisfy: 0.5 ≤ Y1 / d1 ≤ 0.8. For example, when the ratio of the interference amount Y1 between the second side surface 212 and the piece to be fixed 200 to the thickness d1 of the housing 201 of the piece to be fixed is less than 0.5, the interference amount between the second side surface 212 and the piece to be fixed 200 is small, and the degree of interference fit between the second side surface 212 and the outer peripheral surface of the piece to be fixed 200 is small, reducing the installation stability of the piece to be fixed 200 and the housing 1, thereby reducing the use stability of the piece to be fixed 200. When the ratio of the interference amount Y1 between the second side surface 212 and the piece to be fixed 200 to the thickness d1 of the housing 201 of the piece to be fixed is greater than 0.8, the degree of interference fit between the second side surface 212 and the outer peripheral surface of the piece to be fixed 200 is large. When the second side surface 212 is in a large deformation state for a long time, it is prone to fatigue, which is not convenient for subsequent use and shortens the service life. Therefore, by setting the thickness d1 of the housing 201 of the piece to be fixed and the interference amount Y1 between the second side surface 212 and the piece to be fixed 200 to satisfy: 0.5 ≤ Y1 / d1 ≤ 0.8, the setting is reasonable, which not only improves the installation stability of the piece to be fixed 200 and the housing 1, improves the use stability of the piece to be fixed 200, but also rationalizes the deformation degree of the second side surface 212 and extends the service life of the second side surface 212, that is, extends the service life of the locking structure 2.

[0043] According to some embodiments of the present invention, referring to Figure 5 and Figure 2 , the first side surface 211 is formed as a curved surface; and / or, the second side surface 212 is formed as a flat surface. For example, the settings of the first side surface 211 and the second side surface 212 include the following situations: First, the first side surface 211 is formed as a curved surface. Second, the second side surface 212 is formed as a flat surface. Third, the first side surface 211 is formed as a curved surface and the second side surface 212 is formed as a flat surface (as shown in Figure 5 ). With such a setting, the first side surface 211 facilitates the movement of the locking block 21 between the locking position and the unlocking position, improving the rotation efficiency of the locking block 21. In addition, the flat surface increases the contact area between the second side surface 212 and the piece to be fixed 200, thereby improving the assembly stability between the second side surface 212 and the piece to be fixed 200 and improving the use stability of the piece to be fixed 200.

[0044] According to some embodiments of the present invention, referring to Figure 2 , Figure 1 and Figure 8, one end of the rotating member 22 passes through the housing 1 and extends to the outside of the housing 1. A gripper 23 is provided at one end of the rotating member 22. When the locking block 21 is in the locking position, the side surface of the gripper 23 facing the locking block 21 is adapted to abut against the side surface of the member to be fixed 200 along the installation direction of the member to be fixed 200 (such as Figure 9 shown in the front-back direction). For example, in Figure 1 , Figure 1 and Figure 8 's example, the front end of the rotating member 22 extends to the front side surface of the housing 1, and the gripper 23 is provided at the front end of the rotating member 22. The rear side surface of the gripper 23 abuts against the front side surface of the member to be fixed 200. With such a setting, the gripper 23 limits the member to be fixed 200 in the front-back direction, preventing the member to be fixed 200 from detaching from the housing 1 from the front side of the housing 1, thereby further improving the assembly stability of the member to be fixed 200 and the housing 1, and further improving the use reliability of the member to be fixed 200.

[0045] According to some embodiments of the present invention, referring to Figure 9 , Figure 1 and Figure 8 , a convex structure 231 is provided on the side surface of the gripper 23 away from the locking block 21. For example, in Figure 9 , Figure 1 and Figure 8 's example, the convex structure 231 is provided on the front side surface of the gripper 23. With such a setting, when the member to be fixed 200 cooperates with the cover 301 of the electrical device 300, the convex structure 231 cooperates with the groove 3021 on the cover 301, facilitating the assembly of the cover 301 and the mounting assembly 100, and improving the assembly stability of the cover 301 and the mounting assembly 100.

[0046] According to some embodiments of the present invention, referring to Figure 9 , a limiting block 12 is provided on the housing 1, and the limiting block 12 limits the rotation of the gripper 23. For example, in Figure 1 's example, the limiting block 12 is provided on the front side surface of the housing 1. When the locking structure 2 is in the locking position, the limiting block 12 is located on the left side of the gripper 23. With such a setting, the limiting block 12 limits the gripper 23, so that after the gripper 23 rotates and contacts the limiting block 12, the locking structure 2 completes the locking, thereby facilitating the judgment of when the locking structure 2 completes the locking and further improving the use convenience.

[0047] According to some embodiments of the present invention, referring to Figure 1 and Figure 1 , an installation space 13 is formed on the housing 1, and a limiting structure 131 is provided at the bottom of the installation space 13. The limiting structure 131 limits the movement of the member to be fixed 200 along the installation direction of the member to be fixed 200 (such as Figure 3 shown in the front-back direction). For example, in Figure 1 andFigure 1 In the example, the to-be-fixed member 200 is installed in the installation space 13 of the housing 1. With such an arrangement, the limiting structure 131 cooperates with a limiting groove (not shown in the figure) on the bottom surface of the to-be-fixed member 200. The end of the limiting structure 131 limits the bottom wall of the limiting groove, so that the limiting structure 131 limits the to-be-fixed member 200 in the front-rear direction, and the outer peripheral side of the limiting structure 131 limits the side wall of the limiting groove, so that the limiting structure 131 limits the to-be-fixed member 200 in the left-right direction, thereby further improving the stability of the to-be-fixed member 200 in the housing 1 and facilitating stable use. However, it is not limited thereto. It should be noted that multiple limiting structures 131 may be provided, and the multiple limiting structures 131 are arranged at intervals in the circumferential direction of the side wall of the installation space 13. The length of the limiting structure 131 in the front-rear direction is not limited either. In the description of the present invention, "multiple" means two or more.

[0048] Further, referring to Figure 3 , the locking structure 2 is provided on the top wall of the installation assembly 100. For example, in Figure 1 's example, the locking structure 2 is installed on the upper side wall of the housing 1. With such an arrangement, the locking structure 2 locks the to-be-fixed member 200 in the up-down direction, improving the stability of the to-be-fixed member 200 in the up-down direction and the reliability of use. In addition, the position of the locking structure 2 is relatively high, facilitating user operation.

[0049] For the to-be-fixed member 200 according to the second aspect embodiment of the present invention, referring to Figure 1 , the to-be-fixed member 200 is adapted to be detachably installed in the installation assembly 100, and the installation assembly 100 is the installation assembly 100 according to the above first aspect embodiment of the present invention. For example, in Figure 4 's example, the to-be-fixed member 200 is installed in the housing 1 of the installation assembly 100. With such an arrangement, the to-be-fixed member 200 can be installed in the installation assembly 100 or detached from the installation assembly 100 according to actual use conditions, improving the flexibility and convenience of using the to-be-fixed member 200 and also improving the applicability of using the to-be-fixed member 200.

[0050] According to some embodiments of the present invention, referring to Figure 4 and Figure 5 , a mating groove 202 is formed on the top surface of the to-be-fixed member 200. When the to-be-fixed member 200 is installed in the installation assembly 100 and the locking block 21 is in the locking position, a part of the locking structure 2 is adapted to be in interference fit in the mating groove 202. For example, in Figure 6 and Figure 5In the example, the mating groove 202 is formed on the upper side surface of the fixing member. When the locking block 21 is in the locking position, the lower part of the locking block 21 fits into the mating groove 202, and the second side surface 212 of the locking block 21 is in interference fit with the bottom wall of the mating groove 202. With such an arrangement, when the locking block 21 is in the locking position, it effectively ensures the cooperation between the locking block 21 and the member to be fixed 200, thereby achieving locking. In addition, the side walls of the mating groove 202 limit the locking block 21 in the front-back direction, further improving the installation stability of the member to be fixed 200 and the mounting assembly 100 during locking.

[0051] According to some embodiments of the present invention, referring to Figure 6 , a support structure 203 is provided inside the member to be fixed 200. The support structure 203 includes a plurality of support segments 2031. One ends of the plurality of support segments 2031 are connected, and the other ends of the plurality of support segments 2031 are respectively connected to a plurality of inner wall surfaces of the member to be fixed 200. One end of one of the plurality of support segments 2031 is connected to the bottom wall of the mating groove 202. For example, in Figure 5 's example, the support structure is arranged inside the member to be fixed 200. There are three support segments 2031. One ends of the three support segments 2031 are connected. One end of one of the three support segments 2031 is connected to the bottom wall of the mating groove 202. The other end of another one of the above three support segments 2031 is connected to the left side wall inside the member to be fixed 200. The other end of yet another one of the above three support segments 2031 is connected to the right side wall inside the member to be fixed 200. The three support segments 2031 are arranged in a substantially triangular shape (such as an equilateral triangular structure). With such an arrangement, when the locking structure 2 is in the locking position, the extrusion force received by the mating groove 202 can be distributed to the left and right side walls of the member to be fixed 200 through the three support segments 2031, thereby improving the structural strength of the member to be fixed 200 and extending the service life of the member to be fixed 200.

[0052] According to some embodiments of the present invention, referring to Figure 5 , a limiting groove (not shown in the figure) is formed on the bottom surface of the member to be fixed 200. When the locking block 21 is in the locking position, the limiting structure 131 of the mounting assembly 100 is adapted to fit into the limiting groove. For example, in Figure 1 's example, the limiting groove is formed by being recessed upward on the lower side surface of the member to be fixed 200, and the limiting groove and the limiting structure 131 are opposite in the up-down direction. When the member to be fixed 200 is installed in the mounting assembly 100, the limiting structure 131 slides into the limiting groove. With such an arrangement, after the limiting structure 131 cooperates with the limiting groove, it limits the member to be fixed 200 in the front-back direction and the left-right direction, further improving the assembly stability of the member to be fixed 200 and the mounting assembly 100. In addition, the cooperation mode between the limiting structure 131 and the limiting groove is simple and easy to assemble, thereby improving the installation efficiency of the member to be fixed 200 and the mounting assembly 100.

[0053] According to some embodiments of the present invention, the to-be-fixed member 200 is a sound box. Thus, the to-be-fixed member 200 can be used to play audio. Wherein, the to-be-fixed member 200 includes a to-be-fixed member housing 201, a main board 204, a battery 205, and a plurality of speakers 206. The main board 204, the battery 205, and the plurality of speaker components 206 are installed in the to-be-fixed member housing 201. When the to-be-fixed member 200 is used for the electrical device 300, the speaker components 206 in the to-be-fixed member 200 are connected to the battery assembly (not shown in the figure) and the control member (not shown in the figure) in the electrical device 300, and the to-be-fixed member 200 is used to emit sound in the electrical device 300. When the to-be-fixed member 200 is separated from the mounting assembly 100 and used alone, the main board 204 and the battery 205 in the to-be-fixed member housing 201 cooperate with the plurality of speakers 206 to emit sound. It should be noted that the plurality of speaker components 206 include a tweeter 2061, a subwoofer 2062, and a midrange speaker 2063.

[0054] The electrical device 300 according to the third aspect embodiment of the present invention, referring to Figure 1 , includes the mounting assembly 100 according to the first aspect embodiment of the present invention above, and / or the to-be-fixed member 200 according to the second aspect embodiment of the present invention above.

[0055] By adopting the above-mentioned mounting assembly 100 and / or the to-be-fixed member 200, the electrical device 300 according to the present invention improves the use convenience and flexibility of the electrical device 300, thereby improving the user experience.

[0056] According to some embodiments of the present invention, referring to Figure 7 , Figure 8 and Figure 10 , the electrical device 300 includes a main body (not shown in the figure) and a cover 301. An installation cavity (not shown in the figure) and an opening 3041 are formed on the main body. The installation cavity and the opening 3041 are communicated, and the installation cavity is used to install the mounting assembly 100. The cover 301 is movably arranged at the opening 3041 to open and close the installation cavity. A protruding portion 302 is formed on one side of the cover 301 facing the mounting assembly 100. A groove 3021 is formed on the protruding portion 302. When the cover 301 closes the installation cavity, the protruding structure 231 of the mounting assembly 100 is fitted in the groove 3021.

[0057] For example, in Figure 13 , Figure 8 and Figure 10In the example, the protruding portion 302 is provided on the rear side surface of the cover body 301. After the to-be-fixed member 200 is taken out from the electrical device 300, the cover body 301 shields the interior of the installation cavity, improving the aesthetics. In addition, the convex structure 231 cooperates with the groove 3021, enhancing the tight fit between the cover body 301 and the installation assembly 100 and improving the stability of the cover body 301 covering the installation cavity. Additionally, the installation assembly 100 is connected to the main body through fasteners (such as bolts), which is simple to operate. Among them, the electrical device 300 can be a vehicle, a ship, etc. When the electrical device 300 is a vehicle, the to-be-fixed member 200 is installed inside the vehicle body (i.e., the main body of the electrical device 300) (such as at the trunk of the vehicle). At the installation cavity of the vehicle body, there is a decorative panel 304, and an opening 3041 is formed on the decorative panel 304. The cover body 301 is hinged to the decorative panel 304 so that the cover body 301 can open or close the installation cavity. It should be noted that a plurality of through holes 11 are formed on the cover body 301, that is, the cover body 301 is generally in a net shape.

[0058] According to some embodiments of the present invention, referring to Figure 13 , Figure 8 , the electrical device 300 further includes a seal 303. The seal 303 is provided on the side of the cover body 301 facing the installation assembly 100. The seal 303 extends along the circumferential direction of the cover body 301. A notch 3031 is formed on the seal 303, and the protruding portion 302 is fitted at the notch 3031. For example, in Figures 10 - 12 , Figure 8 's example, the seal 303 is connected to the rear side surface of the cover body 301, that is, the seal 303 is located between the cover body 301 and the housing 1 of the installation assembly 100. With such a setting, the seal 303 improves the sealing performance of the assembly between the cover body 301 and the housing 1. After the to-be-fixed member 200 (such as a speaker) emits sound, the seal 303 can prevent the sound from passing out between the cover body 301 and the housing 1, enabling the sound to pass out only from the plurality of through holes 11 on the cover body 301 and improving the sound quality. In addition, the notch 3031 is provided to avoid the protruding portion 302, facilitating the cooperation between the groove 3021 on the protruding portion 302 and the convex structure 231. Additionally, the seal 303 extends circumferentially. When the cover body 301 is in a closed state, the overall compression state of the seal 303 can balance the pressing force in the front-rear direction.

[0059] According to some embodiments of the present invention, referring to Figures 10 - 12 Figure 8, the seal 303 is in an interference fit between the mounting assembly 100 and the cover 301. The distance between the cover 301 and the mounting assembly 100 is d2, and the interference amount of the seal 303 with the mounting assembly 100 is Y2. Wherein, d2 and Y2 satisfy: 1.1 ≤ Y2 / d2 ≤ 1.3. With such a setting, both the mating tightness between the cover 301 and the mounting assembly 100 is improved, and the fatigue resistance of the seal 303 is enhanced, thereby prolonging the service life of the seal 303. Among them, the ratio of the distance d2 between the cover 301 and the mounting assembly 100 to the interference amount Y2 of the seal 303 with the mounting assembly 100 further satisfies Y2 / d2 = 1.2.

[0060] According to some embodiments of the present invention, the seal 303 is a silicone part; and / or, the hardness of the seal 303 is D, and D satisfies: 45 degrees ≤ D ≤ 55 degrees. For example, the setting of the seal 303 includes the following situations: First, the seal 303 is a silicone part. Second, the hardness of the seal 303 is D. Third, the seal 303 is a silicone part, and the hardness of the seal 303 is D, and D satisfies: 45 degrees ≤ D ≤ 55 degrees.

[0061] Thus, the silicone part has good soft elasticity and has tightness after being compressed, thereby improving the sealing effect of the seal 303. In addition, the silicone part has corrosion resistance, prolonging the service life of the seal 303. Additionally, the hardness of the seal 303 is reasonably set, which not only improves the structural strength of the seal 303 but also effectively enhances the elasticity of the seal 303, thereby improving the tightness of the seal 303 and also prolonging the service life of the seal 303. Among them, the hardness of the seal 303 is Shore hardness D.
