The present disclosure relates to the technical field of electronic devices, and in particular, to a shell module for packaging an electronic device and an electronic device.
A shell module for packaging an electronic device usually includes two parts that are detachably connected, and an engagement-locking structure is usually used as a detachable connection structure. After the two parts of the shell module are correctly assembled, an engagement portion on one part of the shell module and a locking portion on the other part of the shell module are locked to achieve connection between the two parts of the shell module.
In the related art, in order to avoid incorrect assembling of the shell module, the engagement-locking structure arranged on two sides of the shell module usually is designed with a difference in spacing. However, due to a dimension of the shell module, it is difficult to achieve a significant difference in spacing, and there is quite a risk of incorrect assembling during the assembling process. Once assembled incorrectly (for example, in reverse), it is easy to cause damage to the engagement-locking structure or the shell module itself.
Therefore, it needs to provide a shell module for packaging an electronic device and an electronic device, to solve the above-mentioned problems in the related art.
The present disclosure aims at the problem of incorrect assembly of a shell module in the related art, and provides a shell module for packaging an electronic device and an electronic device. By providing a protruding inserting portion on a first side of the first shell, in an aspect, it can form an obvious identification on the appearance and distinguish the assembly direction; in another aspect, incorrect assembly won't be performed, thereby avoiding incorrect assembly during the assembling process; in still another hand, the inserting portion can serve as a positioning & guiding structure in the assembling process, assisting in the assembly of the first and second shells to improve the assembly efficiency.

Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall into a protection scope of the present disclosure.
Referring to
In this embodiment, the first shell 11 includes a top plate 111 and a side plate 112 formed by bending and extending from an edge of the top plate 111 towards the second shell 12. The top plate 111 is spaced apart from the second shell 12, and the side plate 112 abuts against a surface of the second shell 12.
The engagement-locking structure 13 includes an engagement portion 131 and a locking portion 132 that are engaged with each other, and the engagement portion 131 and the locking portion 132 are detachably connected to each other. The engagement portion 131 is fixed to the first shell 11, the locking portion 132 is fixed to the second shell 12. The engagement portion 131 one-to-one corresponds to the locking portion 132. As an improvement, the engagement portion 131 and the first shell 11 are formed into one piece to ensure structural stability.
In this embodiment, the engagement-locking structure 13 is a buckle structure, a male connector of the buckle structure is the engagement portion, and a female connector of the buckle structure is the locking portion. The engagement-locking structure 13 may also be in other detachable engagement-locking forms, such as an inserting column & a slot, a latch & a lock, etc.
The engagement portion 131 is fixed to an outer surface of the side plate 112. The locking portion 132 is fixed to a surface of the second shell 12 abutting against the side plate 112, and the locking portion 132 is located at an outer periphery of the side plate 112.
In an electronic device, the shell module 10 for packaging the electronic device generally also serves to fix internal electronic components. Due to the asymmetry in the distribution positions of the electronic components, the shape of the shell module 10 for packaging the electronic device generally also has asymmetry, therefore the assembling direction needs to be distinguished during assembly, and the internal electronic components may be damaged in a case of reverse assembly. Therefore, the directions of the first shell 11 and the second shell 12 need to be distinguished, to ensure the correctness of the assembly direction.
In order to describe the assembly direction of the shell module 10 for packaging the electronic device more clearly, the directions of the first shell 11 and the second shell 12 are defined as follows: the first shell 11 includes a first side 11A and a second side 11B arranged opposite to each other, and the second shell 12 includes a third side 12A and a fourth side 12B arranged opposite to each other. Each of the first side 11A and the second side 11B of the first shell 11 is provided with the engagement portion 131, and each of the third side 12A and the fourth side 12B of the second shell 12 is provided with the locking portion 132. The number of the engaging portions 131 on the first side 11A is equal to the number of the engaging portions 131 on the second side 11B of the first shell 11.
The correct assembling process is as follows: the engagement portions 131 on the first side 11A of the first shell 11 are one-to-one correspondingly locked to the locking portions 132 on the third side 12A of the second shell 12, and the engagement portions 131 on the second side 11B of the first shell 11 are one-to-one correspondingly locked to the locking portions 132 on the fourth side 12B of the second shell 12.
In order to achieve a better assembly effect, the first side 11A of the first shell 11 is further provided with a protruding inserting portion 110. The inserting portion 110 plays a role in distinguishing from an appearance, such that one can visually distinguish the first side 11A from the second side 11B of the first shell 11. In this way, an orientation of the first shell 11 can be quickly determined during a material taking process, thereby ensuring that the assembly direction of the first shell 11 is correct. As an improvement, the inserting portion 110 and the first shell 11 are formed into one piece.
In an example, only one inserting portion 110 is provided. However, more than one inserting portion 110 may also be provided according to actual requirements, which will not be limited in the present disclosure.
The inserting portion 110 is located between any two of the engagement portions 131 on the first side 11A of the first shell 11. Two of the locking portions 132 located on the third side 12A of the second shell 12 that are nearest to the inserting portion 110 are spaced apart to form an inserting space 141, and two of the locking portions 132 located on the fourth side 12B of the second shell 12 that are nearest to the inserting portion 110 are spaced apart to form a non-inserting space 142. An orthographic projection of the inserting portion 110 onto the inserting space 141 completely falls within the inserting space 141, and at least art of an orthographic projection of the inserting portion 110 onto the non-inserting space 142 is located outside the non-inserting space 142.
In the assembling process, when reverse assembly is performed, that is, when the first side 11A of the first shell 11 is trying to assembly to the fourth side 12B of the second shell 12, the inserting portion 110 cannot be smoothly inserted between two adjacent locking portions 132 on the fourth side 12B of the second shell 12; when correct assembly is performed, that is, when the first side 11A of the first shell 11 is trying to be assembled to the third side 12A of the second shell 12, the inserting portion 110 can be smoothly inserted between two adjacent locking portions 132 on the third side 12A of the second shell 12. The inserting portion 110 ensures an unique assembly direction, thereby avoiding incorrect assembly during the assembling process.
In this embodiment, in an example, the inserting portion 110 is a U-shaped rib, including a bottom edge 1101 and two side edges 1102, the two side edges 1102 are at two ends of the bottom edge 1101 and spaced apart from each other. The two side edges 1102 and the bottom edge 1101 form a U-shaped structure. After the assembly is completed, the two side edges 1102 respectively abut against the two locking portions 132 at two sides of the inserting space 141.
The two side edges 1102 can play a guiding role in the assembling process, allowing the first shell 11 and the second shell 12 to move along extending directions of the side edges 1102, thereby maintaining stability in the assembling process.
Referring to
In this embodiment, the inserting portion 120 is a cylindrical protrusion. Two sides of the cylindrical protrusion respectively abut against two locking portions 132 located at two sides of the inserting space 141. The cylindrical protrusion has a diameter not greater than a minimum width of the inserting space 141, to ensure that the inserting portion 120 can be smoothly inserted at a position between the two locking portions 132.
Referring to
In this embodiment, the inserting portion 130 includes at least one group of bumps spaced apart in a horizontal direction. Each group of bumps includes two bumps, and the two bumps respectively abut against two locking portions 132 located at two sides of the inserting space 141.
On the basis of Embodiment I, this embodiment omits the structure of the bottom edge 1101, and simplifies the continuous side edge 1102 by providing multiple spaced bumps, thereby making the structure more simplified.
Referring to
In this embodiment, the electronic component 50 may be an MEMS device. The shell module 10 for packaging the electronic device is provided with a sound outlet hole in communication with the outside at a position corresponding to a sound outlet of the MEMS device, and the sound generated by the MEMS device propagates outward through the sound outlet hole.
It should be noted that the shell module 10 for packaging an electronic device in this embodiment may be replaced with the shell module 20 for packaging an electronic device in Embodiment II or the shell module 30 for packaging an electronic device in Embodiment III, which will not affect the expression of this embodiment.
The above description merely illustrates some embodiments of the present disclosure, and it should be noted that those skilled in the art can also make improvements without departing from a concept of the present disclosure, but these all improvements shall fall into a protection scope of the present disclosure.
