Housing assembly

This invention relates to a housing assembly, and more particularly to a housing assembly having a good fit.

1 is a schematic view of a conventional housing assembly. Referring to FIG. 1 , the materials of the first housing 110 and the second housing 120 of the conventional housing assembly 100 are all plastic, and the assembly ribs 112 are disposed on the side of the first housing 110. The assembly recess 122 is disposed at the corresponding portion of the second housing 120, and in order to prevent the first housing 110 and the second housing 120 from being assembled together, the airtightness is poor due to assembly tolerances, and the waterproof ratio is lowered, so An additional waterproof rubber ring 130 is formed in the assembly groove 122.

However, the waterproof rubber ring 130 is not easily placed in the assembly groove 122 of the second casing 120, and has difficulty in assembly. In addition, the conventional housing assembly 100 has a first housing 110, a second housing 120, and a waterproof rubber ring 130. At least three kinds of materials need to be managed and stored.

2 is a schematic view of another conventional housing assembly. Referring to FIG. 2, another housing assembly 200 is provided with a waterproof rubber strip 220 having a circular cross section on the side of the first housing 210, and then pressing the first housing 210 to the second housing. On the 230, the elastic waterproof rubber strip 220 is deformed by pressing to seal the gap between the first casing 210 and the second casing 230. However, the waterproof rubber strip 220 is also easily damaged after being pressed, or hardened due to a long time, resulting in poor sealing effect.

The present invention provides a housing assembly having a good adhesion effect.

The present invention provides a housing assembly including a first housing and a second housing, the first housing having a first assembly surface and the second housing having a second assembly surface and a spike, wherein The first hardness of a casing is smaller than the second hardness of the second casing, and when the first casing and the second casing are assembled, the first assembly surface and the second assembly surface abut each other, and the spikes are inserted into the first An assembly surface and the first assembly surface is in close contact with the spike.

In an embodiment of the housing assembly of the present invention, the cross-sectional shape of the spike is triangular in shape.

In an embodiment of the housing assembly of the present invention, the first housing has a first portion and a second portion, the first portion and the second portion are two-shot injection molding, and the first portion has the first portion. Hardness, while the second portion has a third hardness and the third hardness is greater than the first hardness.

In an embodiment of the housing assembly of the present invention, one of the first housing and the second housing has a plurality of fastening hooks, and the other of the first housing and the second housing has a plurality of An opening, and the fixing hook is correspondingly fastened to the opening.

In an embodiment of the housing assembly of the present invention, a plurality of screws that are locked into the second housing through the first housing are further included.

Based on the above, in the housing assembly of the present invention, since the second housing is provided with a spike, and the portion of the first housing that is in contact with the second housing is made of a soft material, the first housing and When the second housings are assembled together, the spikes may protrude into the first assembly surface of the first housing, and the first housing may be deformed by the penetration of the spikes to accommodate the shape of the spikes, and the second shell Close together.

The above described features and advantages of the present invention will be more apparent from the following description.

3 is a schematic view of a housing assembly in accordance with an embodiment of the present invention. The housing assembly 300 includes a first housing 310 and a second housing 320. The first housing 310 has a first assembly surface 312, and the second housing 320 has a second assembly surface 322 and a spike. 324, wherein the first hardness of the first housing 310 is relatively smaller than the second hardness of the second housing 320, and when the first housing 310 and the second housing 320 are assembled together, the first assembly surface 312 and the second assembly The surface 322 abuts and the spike 324 projects into the first assembly surface 312 and the first assembly surface 312 is in close contact with the spike 324.

With reference to FIG. 3 , in the embodiment, the first housing 310 has a first portion 314 and a second portion 316 , and the first portion 314 and the second portion 316 are formed by two injection moldings. The casing 310, wherein the material of the first portion 314 is a relatively soft material such as rubber, and has the first hardness, and the second portion 316 is made of a relatively hard material such as plastic, and has a third portion. The hardness, and the third hardness of the second portion 316 is greater than the first hardness of the first portion 314. In addition, the first assembly surface 312 is located at the first portion 314, and the cross-sectional shape of the spike 324 is triangular. Moreover, the material of the second housing 320 may be the same as the second portion 316 of the first housing 310, that is, the second hardness may be the same as the third hardness. Of course, the material of the second housing 320 may also be different from the second portion 316 of the first housing 310, that is, the second hardness is different from the third hardness, and the second housing 320 and the first housing 310 are The second part of the 316 is hard and soft, which is determined according to the actual design requirements.

In detail, when the first housing 310 and the second housing 320 are assembled together, the assembler places the first housing 310 on the second housing 320 to make the first assembly surface 312 and the second assembly surface. The 322 phase abuts, and since the first stiffness of the first portion 314 is minimal, the spike 324 is pushed into the first assembly surface 312 with the first portion 314 and the spike 324 pressed against each other, and the first portion 314 The shape is tapered to conform to the shape of the spike 324, and the first assembly surface 312 is in close contact with the spike 324. By the arrangement of the spikes 324 and the deformation of the first portion 314, the first assembly surface 312 and the spikes 324 can be completely brought into close contact, thereby improving the waterproof capability of the casing assembly 100.

In the above, the first housing 310 can further have a plurality of fixing hooks 318, and correspondingly the second housing 320 can have more openings 326, and the fixing hooks 318 are correspondingly fastened to the opening 326, so as to make the first The relative positions of the housing 310 and the second housing 320 are fixed to each other as shown in FIG.

Referring also to FIG. 4, in order to increase the assembly stability of the first housing 310 and the second housing 320, the housing assembly 300 may further include a plurality of screws 330, and the screws 330 pass through the first housing 310 and are locked. In the second housing 320.

The fixing manner of the first housing 310 and the second housing 320 is the fastening manner corresponding to the fixing hook 318 and the opening 326, or is locked by the screw 330, and one of them may be selected, or as in the present embodiment. Both the buckle and the lock are used.

In summary, in the housing assembly of the present invention, because the spike provided on the second housing will protrude into the first assembly surface of the first housing, and the first assembly surface will have a correspondingly sharp shape. The deformation is such that the first assembly surface is in close contact with the spike, and there is no gap between the first assembly surface and the spike. Therefore, the first housing and the second housing are completely close together, and the housing assembly has a good adhesion and waterproof effect.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
