Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.
It should be noted that the terms of left, right, upper and lower directions in the embodiments of the present invention are only relative concepts or are referred to the normal use state of the product, and should not be considered as limiting.
Referring to fig. 1 to 3, an embodiment of the present invention provides an earphone housing, which includes a first shell 100, a second shell 200, a decorative shell 300, and at least one screw (not shown).
Between the first casing 100 and the second casing 200 is formed a receiving cavity for receiving electronic devices, wherein the electronic devices may include a speaker, a microphone, and the like.
The first casing 100 has at least one screw hole 101 on a side facing the second casing 200, the second casing 200 has at least one through hole 201, and each screw passes through one through hole 201 and is screwed to one screw hole 101. Therefore, when the contact position of the first casing 100 and the second casing 200 is subjected to an external force towards the accommodating cavity, the contact position of the first casing 100 and the second casing 200 will not deform towards the accommodating cavity, so that the first casing 100 and the second casing 200 are separated from each other.
The decorative shell 300 is attached to the outer surface of the second casing 200 far from the first casing 100, is connected to the second casing 200 in a snap-fit manner, and covers the through holes 201. Therefore, the decorative shell 300 covers the through holes 201, so that the through holes 201 are prevented from being exposed, and the attractiveness of the earphone shell is improved. In addition, since the decorative shell 300 is attached to the outer surface of the second shell 200 far away from the first shell 100, even if the joint position of the decorative shell 300 and the second shell 200 receives an external force (similar to the joint position of the first shell 100 and the second shell 200 receiving an external force toward the accommodating cavity), the decorative shell 300 and the second shell 200 deform in the same direction, and the fastening relation between the decorative shell 300 and the second shell 200 is not easy to loosen.
From the above, the utility model discloses a technological effect is: through the screw connection between the first casing 100 and the second casing 200 and the fastening between the second casing 200 and the decorative shell 300, not only the casing on the outer surface of the second casing 200 is prevented from being exposed, but also the situation that the first casing 100 and the second casing 200 are easily separated from each other when the joint position of the first casing 100 and the second casing 200 is subjected to an external force towards the accommodating cavity is avoided.
It should be noted that, the hole wall of the through hole 201 may be provided with a thread or may not be provided with a thread, wherein, if the hole wall of the through hole 201 is provided with a thread, in the assembling process, all the screws may be screwed to the corresponding screws and screwed to the through holes 201, and then all the screws are screwed to the corresponding screw holes 101, and if the hole wall of the through hole 201 is not provided with a thread, each screw is directly screwed to the corresponding screw hole 101 through the corresponding through hole 201. In this embodiment, the hole wall of the through hole 201 is not provided with the screw hole 101.
In one embodiment, a snap connection is also provided between the first housing 100 and the second housing 200. During the assembly process, the first housing 100 and the second housing 200 may be connected by a snap connection, and then screws may be screwed into the screw holes 101. Based on this structure, it is advantageous to further improve the connection stability between the first and second housings 100 and 200.
Referring to fig. 2 and fig. 3, in an embodiment, at least one stud 110 is disposed on a side surface of the first casing 100 facing the second casing 200, each stud 110 is located in the receiving cavity, and an end surface of a free end of the stud 110 is provided with a screw hole 101. Thus, the depth of the screw screwed into the screw hole 101 can be increased without increasing the thickness of the first shell 100, which is beneficial to enhancing the screwing stability between the screw and the first shell 100.
Further, the free end of the stud 110 abuts the second housing 200. If the free end of the stud 110 does not abut against the second housing 200, that is, a gap is left between the free end of the stud 110 and the second housing 200, after the screw is screwed into the screw hole 101, the screw may generate a pressing force on the second housing 200 in a direction toward the first housing 100, and the position corresponding to the second housing 200 deforms toward the first housing 100, and based on the structural design, the free end of the stud 110 abuts against the second housing 200, the stud 110 may prevent the second housing 200 from deforming because the free end of the stud 110 abuts against the second housing 200, and the stud 110 may limit the deformation of the second housing 200.
Further, at least one abutting column 210 is disposed on a side surface of the second housing 200 facing the first housing 100, each abutting column 210 is located in the accommodating cavity, and each abutting column 210 abuts against one stud 110; the opening position of each through hole 201 is opposite to the position of one abutting column 210. During application, the stud 110 can prevent the second housing 200 from deforming when it abuts against the abutment post 210. Based on the structural design, the length of the stud 110 is reduced, the manufacturing difficulty of the first housing 100 is reduced, and the manufacturing cost is reduced, for example, the first housing 100 is usually manufactured and formed by an injection molding process, for example, in the length process of the stud 110, a larger hole depth is required for a forming hole of a corresponding mold, which is not favorable for manufacturing a forming mold for injection molding the first housing 100, and is also not favorable for demolding the first housing 100.
Furthermore, the end surface of the free end of the abutting column 210 is provided with a limit hole 2101, the limit hole 2101 is in inserting fit with the free end of the corresponding stud 110, the hole bottom of the limit hole 2101 abuts against the free end of the corresponding stud 110, and the cross-sectional shape of the limit hole 2101 is the same as the cross-sectional shape of the free end of the corresponding stud 110. After the free end of the stud 110 is inserted into the limiting hole 2101, the abutment post 210 will limit the lateral deviation of the stud 110.
Referring to fig. 2 and 3, in one embodiment, at least one screw is configured with a washer 400. The washer 400 is provided to disperse the pressing force of the screw to the second housing 200, so that the screw can be effectively prevented from damaging the second housing 200.
