Specific implementation

[0026] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0027] Referring to Figures 1-5 The embodiment of the utility model provides a shell structure convenient for local spraying, which comprises integrally formed half shell 1 and integrally formed decorative plate 2. The half shell 1 and the decorative plate 2 are injection molded or sheet metal molded. Generally, the corresponding material is selected for molding processing according to the structural requirements of the interactive device on the shell. Specifically, the mounting portion 101 protruding outward is arranged in the middle of the half shell 1. The mounting portion 101 is provided with the first boss 102. The size of the first boss 102 is smaller than the size of the mounting portion 101. The second boss 103 protruding outward and located at the edge of the first boss 102 is arranged on the first boss 102. The first strip hole 104 is arranged on the first boss 102 and located on one side of the second boss 103. When the decorative plate 2 is mounted, the first boss 102, the second boss 103 and the first strip hole 104 are used to position in multiple dimensions.

[0028] On the decorative plate 2, there is a first groove 201 which is buckled with the first boss 102. On the decorative plate 2, there is a notch structure 202 which abuts against the second boss 103. On the decorative plate 2, there is a raised strip portion 203. The strip portion 203 is inserted and cooperated with the first strip hole 104. The first groove 201 is buckled on the first boss 102. At the same time, the notch interface abuts against the side edge of the second boss 103, and the strip portion 203 is limited by the first strip hole 104. Thus, the positioning of the decorative plate 2 is realized in three dimensions, ensuring that the decorative plate 2 can be well fitted and installed with the installation part 101, and the overall visual impact is small. At the same time, on the first boss 102, a plurality of installation holes 105 are arranged at intervals. On the decorative plate 2, a plurality of connecting columns 204 inserted into the installation holes 105 are arranged at intervals. In the installation holes 105, there are fasteners for locking the connecting columns 204. After the fasteners are locked on the connecting columns 204, the decorative plate 2 is reliably fixed on the installation part 101.

[0029] Through the improved structure above, the decorative plate 2 can be installed on the semi - shell 1 after spraying, and it does not affect the overall structural stability of the semi - shell 1. Thus, it solves the situation in the prior art that the parts other than the spraying part need to be covered and protected, resulting in a too long spraying process due to delicate operations. The improved structure can ensure that the semi - shell 1 will not be polluted by the spraying process at all, and the protection operation process is also avoided when spraying the decorative plate 2. Thus, the efficiency of the entire shell manufacturing link is improved.

[0030] In order to facilitate the connection between the strip portion 203 and the inside and outside of the entire semi - shell 1, a second strip hole 205 is opened on the strip portion 203.

[0031] At the same time, on the semi - shell 1, there is a stepped surface 106 inclined from the installation part 101 to the edge position. In the stepped surface 106, there is a first installation groove 107 and a through - hole 108 in the shape of a "convex" above the first installation groove 107. The inclined stepped surface 106 is used to install external interaction parts devices, while the first installation groove 107 and the through - hole 108 are used to realize the integrated installation of internal devices and limit and lock the external interaction part.

[0032] Specifically, on the semi - shell 1, at the edges on both sides of the first installation groove 107, there are grooves 109, and the grooves 109 are convenient for the hand to exert force when holding.

[0033] Specifically, the semi-shell 1 is provided with a first connecting portion 110 and a second connecting portion 111 extending outward from the bottom of the mounting portion 101. The first connecting portion 110 and the second connecting portion 111 are spaced apart. The first connecting portion 110 and the second connecting portion 111 are used to connect to the back shell at the bottom to improve the structural connection stability.

[0034] Furthermore, a frame portion 112 is provided on the semi-shell 1, connecting the first connecting portion 110 and the second connecting portion 111. The frame portion 112 is flush with the surface of the second boss 103. The frame portion 112 further enables the installation of internal components. At the same time, the frame portion 112 enhances the structural strength of the first connecting portion 110 and the second connecting portion 111, so that the overall semi-shell 1 can have a stable structure when installed on the back shell, and meets the requirement of the frame portion 112 to accommodate and install internal components.

[0035] Specifically, in order to strengthen the structure of the entire semi-shell 1, a number of reinforcing ribs 113 are provided inside the semi-shell 1.

[0036] Meanwhile, a plurality of mounting posts 114 are provided on the inner sidewall of the semi-shell 1 at intervals along the edge. The mounting posts 114 are used to be mounted on the back shell. The mounting posts 114 are provided with internal threaded holes to cooperate with the back shell to lock the entire semi-shell 1. When connecting the semi-shell 1 and the back shell, the positioning can be performed in advance. A plurality of positioning pieces 115 are provided at the edge of the inner sidewall of the semi-shell 1.
