Description
Technical Field
The present invention relates to a housing device and an assembling method, and more particularly, to a housing device and an assembling method that ensure a waterproof function and assembling convenience.
Background
The sealing mode of the waterproof and steam-tight rubber ring at present can be a mode of compressing the rubber ring and is divided into a vertical compression mode and a horizontal compression mode.
Referring to fig. 1, fig. 1 is a schematic diagram of a housing device with a vertically compressed rubber ring in the prior art. As shown in fig. 1, a groove for placing the rubber ring is formed on one side of the casing, and the rubber ring is compressed up and down to achieve air tightness by using the force of clamping the casing at the two sides up and down. The structure has the disadvantages that the compression amount of the rubber strip (the gap between the two side machine cases) is controlled very accurately, and if the gap of a certain area is slightly enlarged, the waterproof or airtight performance is affected due to insufficient compression of the rubber strip. However, such a case is often warped due to complicated shape or double-material injection, etc., in the existing machine, the case at both sides of the enlarged gap needs to be pulled back by the force of the locking screw, and the pulling force of the screw needs to be resisted by the resilience force of the compression of the rubber strip, so that the case needs to be locked by matching with very dense screws in the vertical compression, and as long as the device has a larger volume and a slightly complicated shape, local water leakage or gas leakage failure is still very easy.
Referring to fig. 2, fig. 2 is a schematic diagram of a housing device with a horizontally compressed rubber ring in the prior art. As shown in figure 2, the staggered position of the upper and lower machine cases is an inner machine case and an outer machine case, the rubber strip is sleeved on the inner machine case, when the machine case at the other side is covered, the rubber strip is sleeved by the outer side, the structure can tolerate a large assembly tolerance, and even if the machine cases at the two sides are slightly opened for some reasons, the compression amount of the rubber strip is not changed, so that the airtight and watertight effect is not influenced. However, the edge of the inner shell bears the inversion force, and the edge of the outer shell bears the eversion force, so the case needs to be designed to be thick and heavy to have enough strength to resist the deformation of the inversion and eversion forces, and is not easy to be applied to a case with too large size.

In this embodiment, the housing device includes a first housing 110a, a second housing 110b, and a rubber ring 120.
The first housing 110a has a first periphery, a first groove 130 and a first hole 150, the first groove 130 is disposed along the first periphery, and the first groove 130 is communicated with the first hole 150. The second casing 110b has a second periphery, a second groove and a second hole, the second groove is disposed along the second periphery, and the second groove is communicated with the second hole. In this embodiment, the structures of the first periphery, the first groove 130 and the first hole 150 of the second housing 110b correspond to the structures of the second periphery, the second groove and the second hole of the first housing 110a, and the main structure of the first housing 110a and the main structure of the second housing 110b may be different. The rubber ring 120 has a first portion and a second portion connected to each other, and the width of the first portion is greater than or equal to the width of the first groove 130, and the width of the second portion is greater than or equal to the width of the second groove.
When in use, the first part of the rubber ring 120 is placed at the opening of the first groove 130, and the first hole 150 is pumped so that the first part is sucked and clamped between the two side walls of the first groove 130; and then the second part is placed at the opening of the second groove, and the second part is sucked and clamped between two side walls of the second groove by pumping air to the second hole, so that the shell device is sealed and assembled.
In practice, the rubber ring 120 may be made of a soft elastic material, such as a rubber-like elastic material or other materials with similar characteristics to rubber materials, and may be specifically made of silicone rubber or rubber. In this embodiment, the shape of the rubber ring 120 corresponds to the shape of the first groove 130, and is square or substantially square, and the corners of two adjacent sides are arc-shaped.
In this embodiment, the first groove 130 is disposed on the first periphery of the first casing 110a, and the shape of the first groove 130 can be designed according to the shape of the first periphery of the first casing 110a, and is similar to the shape of the rubber ring 120, in practical operation, the size of the first groove 130 can be slightly smaller (such as the width) than the size of the rubber ring 120 (specifically, the size of the first portion of the rubber ring 120), so that the first portion of the rubber ring 120 can be smoothly placed into the first groove 130 and tightly clamped between two sidewalls of the first groove 130 by its own elastic deformation. In this embodiment, the first groove 130 may be square, and the corners of the first groove are arc-shaped, and the first groove 130 is composed of a bottom surface 130c and a pair of inner side surfaces 130a and 130b, wherein the pair of inner side surfaces 130a and 130b extend perpendicularly from two sides of the bottom surface 130 c. The first groove 130 is used for placing the first portion of the rubber ring 120 therein, and the outer peripheral surface (at least the outer peripheral surface of the first portion) of the rubber ring 120 is closely attached to the bottom surface 130c and the inner side surfaces 130a and 130b of the first groove 130.
In practice, the first housing 110a may further have a third groove 140 with a narrower width than the first groove body, i.e. the width of the third groove is smaller than the width of the first groove 130. The third trench 140 and the first trench 130 both extend along the first periphery, and the third trench 140 communicates with the bottom of the first trench 130 (specifically, the third trench 140 communicates with the bottom surface 130c of the first trench 130 or the bottom of the first trench 130 is considered to be provided with the third trench) and the first hole 150, so that the first trench 130 communicates with the first hole 150 through the third trench 140. When the first hole 150 is subsequently pumped, since the third groove 140 is disposed and communicated with the bottom of the first groove 130, the first portion of the rubber ring 120 is conveniently pumped to the bottom of the first groove 130 and even squeezed into the third groove 140. In practice, when the first portion of the rubber ring 120 is squeezed into the first groove 130, the first portion does not fill the third groove, so that the negative pressure of the air suction can be uniformly applied to the entire rubber ring through the unfilled third groove (i.e., the thin groove), so that the entire rubber ring can be uniformly sucked.
In practice, the second housing 110b may further have a fourth groove with a narrower width than the second groove body, i.e. the width of the fourth groove is smaller than the width of the second groove. The fourth trench and the second trench extend along the second periphery, and the fourth trench communicates with the bottom of the second trench (specifically, the fourth trench communicates with the bottom of the second trench or the bottom of the second trench is considered to be provided with the fourth trench) and the second hole, so that the second trench communicates with the second hole through the fourth trench. When the second hole is subsequently pumped, the fourth groove is arranged and communicated with the bottom of the second groove, so that the second part of the rubber ring 120 is conveniently pumped to the bottom of the second groove and even extruded into the fourth groove. In practical operation, when the second portion of the rubber ring 120 is squeezed into the second groove, the second portion does not fill the fourth groove, so that the negative pressure of the air suction can be uniformly applied to the entire rubber ring through the unfilled fourth groove (i.e., the thin groove), so that the entire rubber ring can be uniformly tightly sucked.
The method for assembling the housing device with the waterproof function of the embodiment includes:
step a, as shown in fig. 4 and 5, providing a first casing 110a, a second casing 110b and a rubber ring 130, wherein the first casing 110a has a first periphery, a first groove 130 and a first hole 150, the first groove 130 is disposed along the first periphery, and the bottom of the first groove 130 is communicated with the first hole 150; the second casing 110b has a second periphery, a second groove and a second hole, the second groove is disposed along the second periphery, and the bottom of the second groove is communicated with the second hole; the rubber ring 120 has a first portion and a second portion connected with each other, the first portion has a width equal to or wider than that of the first groove 130, and the second portion has a width equal to or wider than that of the second groove, that is, the width of the first portion is greater than or equal to that of the first groove 130, and the width of the second portion is greater than or equal to that of the second groove;
step B, placing the first portion of the rubber ring 120 at the opening of the first groove 130 of the first casing 110a, and sucking the first portion of the rubber ring 120 into the first groove 130 by sucking the air from the first hole 150 and clamping the first portion between two sidewalls of the first groove 130 due to elastic deformation. In practical operation, during the process of evacuating the first hole 150, the first portion of the rubber ring 120 can be deformed and gradually sucked into and clamped between the inner side surfaces 130a, 130b and the bottom surface 130c of the first groove 130; when the first housing 110a has the third groove 140, the first portion of the rubber ring 120 can be further deformed to be embedded in the third groove 140 and sucked and clamped between two sidewalls of the third groove 140, and generally, the first portion does not fill the third groove 140.
Step C, as shown in fig. 6, the second portion of the rubber ring 120 is placed at the opening of the second groove of the second housing 110b, and the second portion of the rubber ring 120 is sucked into the second groove by pumping the second hole and clamped between the two sidewalls of the second groove due to elastic deformation. In practical operation, during the process of pumping the second hole, the second portion of the rubber ring 120 is deformed and gradually sucked into and clamped between the two sidewalls of the second groove; when the second housing 110b has a fourth groove with a width narrower than that of the second groove body, the second portion of the rubber ring 120 can be further deformed to gradually embed into the fourth groove and be sucked and clamped between two side walls of the fourth groove, and generally, the second portion does not fill the fourth groove.
In practice, the assembling method may further include a step D of sealing the first hole 150 and the second hole with rubber stoppers or stickers, thereby completing the sealing assembly.
In the present embodiment, the above structure has a very high tolerance to the gap between the first casing 110a and the second casing 110b, and the sealing can be maintained even if the gap between the casings is slightly opened due to local deformation, falling, or various reasons. The problem of among the vertical and horizontal compression mode of current model, plane single-point failure will leak gas is solved.
In this embodiment, the first casing 110a and the second casing 110b have the same structure (at least the connecting portion has the same structure) and perform the same operation, so that the first casing 110a and the second casing 110b are equally stressed, the problem of one-side casing eversion is avoided, the casing does not need to be made thick for strength, and the casing can be applied to a large-size casing.
In this embodiment, the rubber ring 120 is deformed due to the air suction performed on the first hole 150 and the second hole, and at this time, a first static friction force F1 in the depth direction of the first groove 130 is generated with the inner side surface of the first groove 130, and a second static friction force F2 in the depth direction of the second groove is generated with the inner side surface of the groove of the second housing 110b, and the first static friction force F1 and the second static friction force F2 are opposite in direction, so that the first housing 110a and the second housing 110b are tensioned, and the problem of opposition of the rubber ring and the screw force in the conventional machine is solved, so that the requirements on the screw locking force and the screw pitch are greatly reduced, and the number of screws can be greatly reduced.
In this embodiment, in order to achieve a higher level of airtightness, one of the outer surface of the rubber ring 120 and the inner surface of the first groove 130 may be uniformly coated with a thin layer of silicone oil, for example, the inner surfaces 130a and 130b and the bottom surface 130c of the first groove 130 may be brushed with silicone oil by a tool, and the silicone oil is just smeared on the surface of the rubber ring 120 during the suction process.
In the embodiment, the rubber ring is thick, the assembly is easier, and no extra space except the shell is occupied.
