DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Embodiment 1:

[0031] like Figure 3-9As shown, the present embodiment provides a housing assembly, including a shell 1, a bracket 2, and a connecting structure. In the present embodiment, the upper portion of the bracket 2 forms a generally U-shaped concave surface that is open upward, the upper end of the shell 1 is open and matches the shape of the bracket 2, the bracket 2 is arranged in the shell 1, and the connecting structure includes a first snap-fit ​​structure 3 and a second snap-fit ​​structure 4 that are arranged between the bracket 2 and the shell 1 at an upper and lower interval. The upper and lower interval arrangement refers to the first snap-fit ​​structure 3 and the second snap-fit ​​structure 4, one of which is arranged between the bracket 2 and the shell 1 and is located at the upper portion, and the other is arranged between the bracket 2 and the shell 1 and is located at the lower portion; the first snap-fit ​​structure 3 includes a first protrusion 5 that is arranged on one of the outer side of the bracket 2 and the inner side of the shell 1 and a first card groove 6 that is arranged on the other; the second snap-fit ​​structure 4 includes a third protrusion 9 that is arranged on the inner side of the shell 1 and an elastic member 10 that is arranged on the bracket 2; when the shell 1 is installed to the bracket 2, the elastic member 10 is deformed and snapped into the third protrusion 9 while the first protrusion 5 and the first card groove 6 are snap-fitted up and down.

[0032] The shell component of this embodiment utilizes the first protrusion 5 of the first snap-fit ​​structure 3 to snap into the first slot 6, and utilizes the elastic member 10 of the second snap-fit ​​structure 4 to deform and snap into the third protrusion 9 to limit the up and down movement of the bracket 2, so that the bracket 2 can be installed in the shell 1 and will not fall out; the entire installation process does not require additional fasteners to fix, but the installation of the shell 1 and the bracket 2 is achieved through the snap-fitting of the first snap-fit ​​structure 3 and the second snap-fit ​​structure 4, and the snap-fitting of the first snap-fit ​​structure 3 and the second snap-fit ​​structure 4 are automatically completed during the process of installing the shell 1 to the bracket 2, so the installation process is simplified, saving time and effort.

[0033] The first buckle structure 3 is arranged above the second buckle structure 4; the housing 1 is used to be sleeved on the outside of the bracket 2 from the upper end of the bracket 2, so that the first protrusion 5 and the first slot 6 are engaged with each other up and down to limit the upward movement of the bracket 2; the elastic member 10 is deformed and engaged with the third protrusion 9 to limit the downward movement of the bracket 2. This arrangement makes the layout of the first buckle structure 3 and the second buckle structure 4 reasonable and meets the installation habits of users.

[0034] Two first buckle structures 3 are provided and are symmetrically arranged on the left and right, and two second buckle structures 4 are also provided and are symmetrically arranged on the left and right. This arrangement can limit the left and right sides of the bracket 2 and evenly force them, so that the bracket 2 and the housing 1 are fixed more firmly.

[0035] The first protrusion 5 is semicircular, and the opening of the semicircular is downwardly disposed, and the shape of the first slot 6 matches the shape of the first protrusion 5. The semicircular first protrusion 5 also imposes certain restrictions on the left and right movement of the bracket 2, and the multi-directional restrictions make the bracket 2 and the housing 1 more securely fixed.

[0036] The middle position of the upper end of the first protrusion 5 is connected to the second protrusion 7, and the middle position of the upper end of the first slot 6 is connected to the second slot 8. When the first protrusion 5 and the first slot 6 are engaged in upper and lower snap-fitting, the second protrusion 7 and the second slot 8 are engaged in snap-fitting. This arrangement can limit the left and right movement of the bracket 2, thereby making the bracket 2 more securely fixed, and the left and right limiting is also achieved by snap-fitting, and the installation is also more convenient. The second protrusion 7 is also provided with a first guide slope 11, which is conducive to guiding the second protrusion 7 to be engaged into the second slot 8, making the installation more convenient.

[0037] The first protrusion 5 is arranged on the outer wall of the bracket 2, and a third card slot 12 is formed between the first protrusion 5 and the outer wall of the bracket 2. The inner wall of the housing 1 is also provided with a fourth protrusion 13 matched with the third card slot 12. In this embodiment, the fourth protrusion 13 is also semi-circular, and the opening of the semi-circular is arranged downward. The first card slot 6 is formed between the fourth protrusion 13 and the inner wall of the housing 1, and the opening direction of the first card slot 6 is opposite to the opening direction of the third card slot 12. When the first protrusion 5 is engaged with the first card slot 6, the fourth protrusion 13 is engaged with the third card slot 12. The first buckle structure 3 not only utilizes the first protrusion 5 to engage with the first card slot 6, but also utilizes the fourth protrusion 13 to engage with the third card slot 12, so that the bracket 2 and the housing 1 are fixed more firmly.

[0038] The elastic member 10 includes a spring sheet, which is formed by cutting two slots 14 through the wall thickness of the bracket 2. An avoidance position 15 matching the third protrusion 9 is also formed below the spring sheet. The elastic member 10 has a simple structure, is easy to process, and is convenient to connect with the third protrusion 9. A second guide slope 16 is also provided on the third protrusion 9. This arrangement is conducive to guiding the elastic member 10 through the third protrusion 9, making installation more convenient.

[0039] In this embodiment, the first protrusion 5 is arranged on the outer wall of the upper part of the bracket 2, and a third card groove 12 is formed between the first protrusion 5 and the outer wall of the upper part of the bracket 2. The fourth protrusion 13 is arranged on the inner wall of the upper part of the shell 1, and the first card groove 6 is formed between the fourth protrusion 13 and the inner wall of the upper part of the shell 1. The opening direction of the first card groove 6 is downward, and the opening direction of the third card groove 12 is upward; the elastic member 10 and the third protrusion 9 are arranged at the lower part of the bracket 2, and the groove 14 is cut upward along the bottom of the bracket 2.

[0040] The installation process of the housing assembly of this embodiment is as follows:

[0041] When the housing 1 is mounted on the bracket 2, the elastic member 10 of the bracket 2 utilizes its own elasticity and is deformed through the third protrusion 9 of the housing 1 under the guidance of the second guide inclined surface 16 of the third protrusion 9; when the housing 1 and the bracket 2 are installed in place, the bottom of the elastic member 10 abuts against the top of the third protrusion 9 to limit the downward movement of the bracket 2, and at the same time, the first protrusion 5 is engaged with the first card slot 6 up and down and the fourth protrusion 13 is engaged with the third card slot 12 to limit the upward movement of the bracket 2, and the second protrusion 7 is engaged with the second card slot 8 left and right to limit the left and right movement of the bracket 2; at this point, the upper, lower, left and right directions of the bracket 2 are all limited, and the bracket 2 can be reliably limited in the housing 1 and will not fall out; the entire installation process does not require additional fasteners for fixing, but through the engagement of the first buckle structure 3 and the second buckle structure 4, the upper, lower, left and right limits of the bracket 2 are achieved and the bracket 2 is fixed in the housing 1, and the engagement of the first buckle structure 3 and the second buckle structure 4 are automatically completed during the process of the housing 1 being installed on the bracket 2, so the installation process is simplified, saving time and effort.
