Description

Technical Field

[0001] The utility model relates to the technical field of speaker boxes, in particular to a speaker box shell which is convenient for assembly and positioning. Background Art

[0002] Smart speakers are the product of speaker upgrades. They are a tool for home consumers to access the Internet using voice, such as ordering songs, shopping online, or getting weather forecasts. They can also control smart home devices, such as opening curtains, setting refrigerator temperature, and heating up water heaters in advance. They have good application prospects and are one of the most popular smart home devices.

[0003] In the prior art, the outer shell of a speaker is composed of an upper shell and a lower shell that can be assembled together. Between the upper shell and the lower shell, one is provided with a through hole and the other is provided with a screw hole. The screw is passed through the through hole and screwed into the screw hole to complete the locking operation of the upper shell and the lower shell.

[0004] However, the inventors found in actual production operations that when the upper shell and the lower shell are assembled, due to the lack of restrictions on the position of the upper shell and the lower shell, such positions include the front-to-back direction and the left-to-right direction; it is difficult to align the through-holes and the screw holes. When the screws pass through the through-holes and are inserted into the screw holes, the screws are often inserted into the screw holes in an oblique state, resulting in the destruction of the threads between the screws and the screw holes when they are screwed together. In severe cases, the screws cannot be reliably screwed together in the screw holes, and the locking operation of the upper shell and the lower shell cannot be completed. The assembly yield is low, which seriously affects the reliable progress of the assembly operation.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Please also refer to Figures 1 to 4 The speaker housing 10 that is convenient for assembly and positioning provided by the embodiment of the present application is now described. The speaker housing 10 that is convenient for assembly and positioning comprises: an upper housing 11 and a lower housing 12.

[0032] The upper shell 11 and the lower shell 12 can be assembled together to enclose a first mounting cavity 13 for mounting components. The upper shell 11 is provided with a first through-hole 111 and a first positioning slot 112, and the lower shell 12 is provided with a first screw hole 121 and a first positioning insert 122. When the upper shell 11 and the lower shell 12 are assembled together, the first positioning insert 122 is inserted into the first positioning slot 112 so that the first through-hole 111 and the first screw hole 121 are arranged coaxially in the vertical direction.

[0033] Specifically, by providing the first positioning block 122 and the first positioning slot 112, after the upper shell 11 and the lower shell 12 are assembled, the first positioning block 122 can be inserted into the first positioning slot 112, so that the upper shell 11 and the lower shell 12 are accurately positioned in the left and right directions and the front and back directions; such a structure allows the first through-hole 111 to be arranged coaxially with the first screw hole 121 after the upper shell 11 and the lower shell 12 are assembled together, so that when the subsequent screw passes through the first through-hole 111 and is screwed into the first screw hole 121, the screw can be screwed vertically into the first screw hole 121, ensuring that the screw will not be screwed obliquely into the first screw hole 121, so as to ensure that the screw can reliably lock the upper shell 11 and the lower shell 12, thereby improving the assembly yield.

[0034] It should be noted here that the first through-hole 111 and the first screw hole 121 are coaxially arranged with a certain tolerance range. By using the first positioning block 122 and the first positioning slot 112, the tolerance value between the first through-hole 111 and the first screw hole 121 can be controlled between 0.05mm and 0.15mm. When the screw is locked between the first through-hole 111 and the first screw hole 121 within this tolerance value range, the screw can be prevented from damaging the thread of the first screw hole 121.

[0035] In some embodiments of the present application, first plug-in side panels 123 are provided on the left and right sides of the lower shell 12, and first plug-in notches 113 are provided on the left and right sides of the upper shell 11; when the upper shell 11 and the lower shell 12 are assembled together, the first plug-in side panels 123 are inserted into the first plug-in notches 113. Utilizing the structure of the first plug-in side panels 123 and the first plug-in notches 113, the first assembly positioning can be completed during the assembly of the upper shell 11 and the lower shell 12 to limit the specific position of the upper shell 11 relative to the lower shell 12 in the left and right directions and the front and back directions. At the same time, the first plug-in side panels 123 on the left and right sides play a certain clamping role, so that after the upper shell 11 and the lower shell 12 are assembled together, the first plug-in side panels 123 can be pressed against the sides of the first plug-in notches 113, thereby preventing the upper shell 11 from loosening and separating from the lower shell 12 during the subsequent locking process of the upper shell 11 and the lower shell 12.

[0036] Specifically, the left-right width of the first plug-in side panel 123 is greater than the left-right width of the first plug-in notch 113. A first screw hole 121 and a first positioning block 122 are located at the top of the first plug-in side panel 123. First through-holes 111 and first positioning slots 112 are located on the left and right sides of the upper housing 11 and are located at the top of the first plug-in notch 113. Two first supporting protrusions 124 are located at the top of the first plug-in side panel 123. These two first supporting protrusions 124 are spaced apart from each other to form a first limiting notch 125. First limiting protrusions 114 are also located on both the left and right sides of the upper housing 11. When the upper and lower housings 11 and 12 are assembled, the first limiting protrusions 114 are inserted into the first limiting notch 125.

[0037] Preferably, a first positioning plug 122 is provided on the upper surface of each first supporting protrusion 124, and a first positioning plug 122, a first limiting notch 125 and a first positioning plug 122 are provided on the top of the first plug-in side plate 123 on each side of the lower shell 12 in sequence from front to back. Such a structure can not only limit the left and right positions of the upper shell 11 and the lower shell 12, but also limit the front and back positions of the upper shell 11 and the lower shell 12.

[0038] More specifically, the first through-hole 111 extends through the upper and lower surfaces of the first limiting protrusion 114. A first boss 126 is provided at the center of the first limiting notch 125. The first screw hole 121 is located at the center of the first boss 126 and extends downward. A first groove 1141 is provided on the lower surface of the first limiting protrusion 114. When the upper and lower shells 11 and 12 are assembled, the first boss 126 can be inserted into the first groove 1141.

[0039] Preferably, the first through-hole 111 includes a first hole body 1111 and a second hole body 1112 arranged vertically, and the first groove 1141 is arranged below the second hole body 1112; the first hole body 1111, the second hole body 1112 and the first groove 1141 are arranged vertically and coaxially, and the diameter of the second hole body 1112 is smaller than the diameter of the first hole body 1111 and the first groove 1141.

[0040] It can be understood that the diameter of the second hole body 1112 is set to be smaller than the diameter of the first hole body 1111 and the first groove 1141. When performing the screw locking operation, the threaded portion of the screw can pass through the first hole body 1111 and the second hole body 1112 in sequence and be screwed into the first screw hole 121. As the threaded portion of the screw gradually screws into the first screw hole 121, the head of the screw rests against the bottom of the first hole body 1111 to complete the locking between the upper shell 11 and the lower shell 12.

[0041] Furthermore, the first supporting protrusion 124 is provided with at least two first hollow portions 1241 penetrating through its left and right side surfaces, and the two first hollow portions 1241 are spaced apart from each other in the front and rear directions; such a structure is beneficial for reducing the weight of the upper shell 11 and the lower shell 12 while improving the strength of the first supporting portion and preventing deformation.

[0042] In other embodiments of the present application, the top peripheral side surface of the first positioning block 122 has a first plugging slope 1221. Such a structure is conducive to improving the smoothness and reliability of the first positioning block 122 being inserted into the first positioning slot 112, and is less likely to get stuck and unable to be inserted, thereby improving the convenience when assembling the upper shell 11 and the lower shell 12. At the same time, at least two first reinforcing ribs 1222 are provided on the left side and / or right side of the first positioning block 122, and the two first reinforcing ribs 1222 are provided one by one corresponding to the front and rear sides of the first positioning block 122; such a structure can improve the strength of the first positioning block 122, and is less likely to cause the first positioning block 122 to deform during the positioning process of the upper shell 11 and the lower shell 12, which is conducive to improving the accuracy of positioning.

[0043] The assembly process of the speaker housing 10 that is easy to assemble and position provided in the present application is described in detail as follows: first, an upper shell 11 and a lower shell 12 are provided; then, in the process of moving the upper shell 11 downward directly above the lower shell 12, the first plug-in side panel 123 can be inserted into the first plug-in notch 113 to perform the first assembly positioning; continuing to move the upper shell 11 downward relative to the lower shell 12, the first positioning plug 122 can be inserted into the first positioning slot 112 to perform the second assembly positioning to adjust the coaxiality between the first through-hole 111 and the first screw hole 121; after the lower surface of the upper shell 11 is against the upper surface of the lower shell 12, a screw is used to pass through the first through-hole 111 and screwed into the first screw hole 121 to complete the assembly operation of the upper shell 11 and the lower shell 12.

[0044] The above is merely a preferred embodiment of the present invention and only specifically describes the technical principles of the present invention. These descriptions are intended only to explain the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention, as well as other specific embodiments of the present invention that can be imagined by those skilled in the art without inventive effort, shall be included within the scope of protection of the present invention.
