Description

  The present invention relates to a housing for an IT device such as a personal computer and its peripheral devices.

  For example, the housing of IT equipment such as a mobile personal computer and an electronic organizer has conventionally been made of plastic, which is lightweight, has excellent strength, and has a high degree of freedom in design.

  By the way, plastic is an insulator and transmits electromagnetic waves.Therefore, there is a problem that an electromagnetic wave generated from an internal device affects peripheral devices and an internal device is affected by an external electromagnetic wave. The case made of metal has a thin metal film formed by vapor deposition or plating to provide electromagnetic shielding, so mass production is inferior and cost is high. There is a problem that a crack may occur due to the change, a metal thin film may peel off due to a change over time, and recycling is troublesome.

  Therefore, there has been proposed a casing formed by a casting method or a forging method, for example, a die casting method, which can be made thinner than a plastic casing and does not require a separate formation of a metal thin film and can be formed into a complicated shape.

  The die casting method can be molded into various shapes by a mold, and has an advantage that, for example, a boss for mounting a component can be cast (the number of separate processing steps can be reduced by that amount), and mass production is also possible. Also, if aluminum or magnesium is molded by a die-casting method, it is not necessary to form a metal thin film as described above, and since it can be reused by being dissolved, it is attracting attention because of excellent recyclability.

  However, a die-cast molded product (or a cast or forged product) formed by the above-described die-casting method has poor surface quality and requires an appearance finishing step, and has a low yield, resulting in poor productivity and high cost. Become.

  In view of the current situation as described above, the present invention focuses on a press-formed product formed by a press working method that does not require a finishing process in order to eliminate the appearance finishing process, and as a result of earnest research, a press-formed product The advantage of using a molded product formed by the casting method or the forging method on the outside, that is, the ability to form a complicated shape of the casting method or the forging method with high productivity, and the thinning of the pressing method and surface shape It is based on the knowledge that both advantages can be complemented by taking advantage of the fact that it is good, and it is possible to integrally mold complex shapes, reduce the number of processing steps, excel in productivity, and reduce the thickness An object of the present invention is to provide a housing for IT equipment which can be reduced in weight and has excellent recyclability and is extremely practical.

  The gist of the present invention will be described with reference to the accompanying drawings.

  A housing for an IT device such as a personal computer and its peripheral devices, which is formed by a casting method or a forging method without integrally molding the frame member 5 constituting the housing 6, and is connected to the IT device 1 main body. A metal inner frame member 2 in which the portion 3 is integrally molded, and a plate formed by a press working method using the same kind of metal as the inner frame member 2 and provided so as to cover the outer exposed surface 2a of the inner frame member 2 The present invention relates to a housing for IT equipment, wherein the frame member 5 is formed by welding the outer frame member 4 in a shape of a laser beam to the frame member 5.

  2. The IT equipment according to claim 1, wherein said inner frame member 2 formed by die casting and said plate-shaped outer frame member 4 formed by press working are each made of aluminum. Pertaining to a housing for use.

  Since the present invention is configured as described above, by exposing the outer exposed surface of the inner frame member formed by the casting method or the forging method by the outer frame member formed by the press working method, it is excellent in productivity. At the same time, it is possible to reduce the thickness and weight, and to excel in recyclability. Moreover, it is possible to perform welding efficiently and to minimize the influence on the appearance quality, and to form a good appearance. It is a housing for IT equipment with excellent properties.

  Further, according to the present invention, the outer frame member is extremely lightweight and excellent in strength, and the outer frame member can form an appearance utilizing the substrate.

  An embodiment of the present invention (how to implement the present invention) which is considered to be preferable will be briefly described with reference to the drawings, showing the operation of the present invention.

  When the connecting portion 3 of the inner frame member 2 of the frame member 5 constituting the housing 6 is connected to the IT device 1 main body and the frame member 5 is attached to the IT device 1 main body, the outer surface of the frame member 5 has the inner frame. The outer frame member 4 that covers the outer exposed surface 2a of the member 2 is exposed.

  Therefore, the outer appearance of the inner frame member 2 formed by the casting method or the forging method has a surface quality at least to the extent that an appearance finishing step is required, but the outer exposed surface 2a of the inner frame member 2 is exposed by press working. The outer frame member 4 formed by the method and having good surface quality is prevented by the outer frame member 4, so that the step of finishing the appearance of the inner frame member 2 becomes unnecessary, and the number of manufacturing steps is reduced, thereby improving productivity. Can be.

  In particular, the inner frame member 2 formed by the casting method or the forging method has a problem in that the quality varies and the yield is low. However, according to the present invention, the inner frame member 2 is formed by the press working method in which the quality is uniform. The outer frame member 4 is welded and joined, so that the appearance finishing step is not required, and even if the inner frame member 2 is formed thin and lightweight, it is favorably supported by the outer frame member 4 to be welded. Is done. That is, even if a cavity appears on the surface or inside, the number of those which are determined to be unusable due to the cavity decreases.

  Accordingly, the outer frame member 4 is formed by a press working method capable of reducing the thickness and weight, and furthermore, even if the inner frame member 2 is made thinner and lighter, a decrease in the yield is prevented. be able to.

  Further, since the inner frame member 2 is formed by a casting method or a forging method, unlike the press working method, the connecting portion 3 can be integrally molded, and the number of parts can be reduced accordingly, and the connecting portion 3 is formed. Therefore, a new process is not required, and the productivity can be improved from this point as well.

  That is, the present invention provides an inner frame member 2 formed by a casting method or a forging method, and an outer frame member 4 formed by the press working method provided to cover the outer exposed surface 2a of the inner frame member 2. By welding and joining with each other, the disadvantages of the casting method or forging method that the surface shape is rough, lack of quality stability and poor yield, and the disadvantage of the pressing method that the complicated shape can not be integrally molded are complemented each other. As a result, the appearance finishing step is not required, the yield is good, and a complicated shape can be formed with good mass productivity.

  In addition, since the inner frame member 2 and the outer frame member 4 are welded and joined with the same kind of metal, they can be reused only by melting them, and are excellent in recyclability and are optimal for environmental problems. Become.

  Furthermore, since this welding is performed by laser welding, since the laser is light having a single wavelength and no phase difference, it is possible to obtain high-density energy by condensing on an extremely small point with an optical lens. By performing welding using this high-density heat source, high-speed deep penetration welding is possible, and there are advantages such as very little effect of welding heat and little welding deformation. Of course, the influence on the outer frame member 4 can be minimized, and a good appearance can be formed.

  Further, for example, when the inner frame member 2 formed by die casting and the outer frame member 4 in the form of a plate frame formed by pressing are made of aluminum, respectively, they are extremely lightweight and excellent in strength. In addition, the outer frame member 4 can form an appearance utilizing the substrate.

  A specific embodiment of the present invention will be described with reference to the drawings.

  This embodiment is a case for an IT device such as a personal computer and its peripheral devices, and is formed by a casting method without integrally molding the frame member 5 constituting the case 6 and connected to the IT device 1 main body. The inner frame member 2 is formed integrally with the inner frame member 2 and the same metal as the inner frame member 2 is formed by a press working method, and is provided so as to cover the outer exposed surface 2a of the inner frame member 2. The frame member 5 is formed by welding the plate-shaped outer frame member 4 to be formed by laser welding.

  In this embodiment, the inner frame member 2 formed by die casting and the outer frame member 4 in the form of a plate formed by pressing are made of aluminum.

  As shown in FIG. 5, the frame member 5 according to the present embodiment is used as an outer frame portion provided at an outer peripheral position of a display of a notebook personal computer as the IT device 1 (that is, an internal structure around the display). To cover).

  The inner frame member 2 is composed of a plate-shaped base 8 and a connecting portion 3 provided on the base 8. Specifically, the connecting portion 3 includes a peripheral wall portion 3a erected on a thin plate frame-shaped base 8 having a rectangular shape in a plan view, and a predetermined position at a tip end portion of the peripheral wall portion 3a (specifically, a long side portion has Hooks 3b protruding outward at two places, one on the short side), and the hooks 3b are connected to the display of the notebook computer as shown in FIG. Is formed so as to be engaged with and connected to a hook 7a formed on the inner peripheral surface of the top plate 7 provided with. The connecting portion 3 is integrally formed by the die casting method as described above, and does not impair productivity.

  The surface opposite to the surface on which the connecting portion 3 is provided is set as the outer exposed surface 2a.

  In the present embodiment, the inner frame member 2 and the inner peripheral surface of the top plate 7 are engaged and connected. However, other configurations, for example, a screw hole is provided in the inner peripheral surface of the top plate 7, An insertion hole through which a screw is inserted may be provided in the connection portion 3 of the inner frame member 2, and the connection may be made by screwing the screw into the screw hole. In this case, the connection portion 3 and the IT device may be connected. The connection with one main body (that is, the internal structure of the IT device 1) can be more reliably performed.

  Further, in the present embodiment, the inner frame member 2 is a casting method that mass-produces an excellent casting with good casting surface quality in a short time with high precision by pressing molten metal into a precision mold at a high temperature. Since it is formed by the die-casting method, even the connecting portion 3 having a more complicated structure can be integrally molded, and the productivity is extremely excellent.

  In addition, the die-casting method has an unknown point because the process consists of a series of complex phenomena such as high-speed flow of a high-temperature viscous fluid (molten metal), filling, rapid solidification, and molding, and it is difficult to form with high yield. However, in this regard, in this embodiment, as described later, welding is performed in a state where the outer exposed surface 2a of the inner frame member 2 is concealed by the outer frame member 4, thereby compensating for the above-described drawbacks and improving the yield. be able to.

  In this embodiment, the inner frame member 2 is formed by a die casting method, but may be formed by a forging method or another casting method.

  The outer frame member 4 is a thin plate frame having substantially the same shape as the base body 8 of the inner frame member 2, and the outer frame member 4 is formed so as to cover the outer exposed surface 2a of the inner frame member 2 as shown in FIG. The width is set equal to the width of the inner frame member 2.

  The width of the outer frame member 4 may be any width as long as the outer exposed surface 2 a of the inner frame member 2 can be concealed, and may be set to be wider than the width of the inner frame member 2. Further, the outer exposed surface 2a may be concealed together with another member constituting the housing 6 or the main body of the IT device 1.

  Further, in the present embodiment, the outer frame member 4 is formed by pressing a plate-shaped material, bending or squeezing the material by a press working method, specifically, a mold attached to a press machine. It is possible to mass-produce products of uniform quality quickly, that is, good yield, thinning is possible, small mass is required, surface quality is excellent, and surface finish utilizing the base material is possible. .

  Further, the outer exposed surface 2a and the outer frame member 4 are formed so that the surfaces that come into contact with the outer exposed surface 2a of the inner frame member 2 are substantially flat. Therefore, the joining between the inner frame member 2 and the outer frame member 4 is performed well.

  The welding connection between the inner frame member 2 and the outer frame member 4 is superimposed so that the outer exposed surface 2a of the inner frame member 2 is concealed by the outer frame member 4 as described above. This is performed by irradiating a laser from the side on which the connecting portion 3 is provided.

  Specifically, as shown in FIG. 3, the welding portion 9 irradiated with the laser and melted is set so as not to affect the appearance of the outer frame member 4.

  In laser welding, since the laser is light with a single wavelength and no phase difference, high-density energy can be obtained by condensing it on an extremely small point with the lens of the optical system, and using this high-density heat source By performing welding, high-speed deep penetration welding is possible, and there are advantages such as very little welding heat influence and little welding deformation. Therefore, it is possible to minimize the influence on the outer frame member 4. it can.

The laser used for laser welding may be a CO ₂ laser, a YAG laser, or the like. The former has a long wavelength, high output, and high oscillation efficiency, and the latter has a short wavelength, low output, and low oscillation efficiency. The former is often used for continuous oscillation, and the latter for pulse oscillation. If the thickness of the weld exceeds 1 mm, it is desirable to use a CO ₂ laser. Further, depending on the material, a second harmonic YAG laser or a semiconductor laser may be used.

  Since the present embodiment is configured as described above, when the connecting portion 3 of the inner frame member 2 of the frame member 5 forming the housing 6 is connected to the IT device 1 main body and the frame member 5 is attached to the IT device 1 main body. The outer frame member 4 that covers the outer exposed surface 2a of the inner frame member 2 is exposed on the outer surface of the frame member 5.

  Therefore, the appearance of the inner frame member 2 formed by the die-casting method has a surface quality that requires at least an appearance finishing step, but the exposure of the outer exposed surface 2a of the inner frame member 2 is performed by a press working method. Since the outer frame member 4 is formed and has good surface quality, the outer frame member 4 is prevented from forming. Therefore, the appearance finishing step of the inner frame member 2 is not required, and the number of manufacturing steps can be reduced and productivity can be improved. .

  In particular, the inner frame member 2 formed by the die casting method has a problem in that the quality varies and the yield is low, but according to the present embodiment, the inner frame member 2 is formed by the press working method in which the quality is uniform. The outer frame member 4 is welded and joined, so that the appearance finishing step is not required, and even if the inner frame member 2 is formed to be thin and lightweight, the outer frame member 4 is well supported by the welded outer frame member 4. You. That is, even if a cavity appears on the surface or inside, the number of those which are determined to be unusable due to the cavity decreases.

  Accordingly, the outer frame member 4 is formed by a press working method capable of reducing the thickness and weight, and furthermore, even if the inner frame member 2 is made thinner and lighter, a decrease in the yield is prevented. be able to.

  Further, since the inner frame member 2 is formed by a die casting method, the connecting portion 3 can be integrally molded unlike the press working, so that the number of parts can be reduced accordingly, and a new part for forming the connecting portion 3 can be obtained. This eliminates the need for a simple process, and in this respect also improves productivity.

  That is, in the present embodiment, the inner frame member 2 formed by the die casting method and the outer frame member 4 formed by the press working method provided so as to cover the outer exposed surface 2a of the inner frame member 2 are provided. By welding and joining, the surface shape is rough, the stability of quality is lacking, the yield is poor, the disadvantage of casting or forging method, and the disadvantage of press processing method, which cannot integrally mold complex shapes, complement each other. This eliminates the need for an external finishing step, improves the yield, and enables extremely complex productivity to be formed with good mass productivity.

  In addition, since the inner frame member 2 and the outer frame member 4 are made of aluminum and are welded to each other, they can be reused only by melting them, and are excellent in recyclability and environmental problems. It will be optimal.

  Furthermore, since this welding is performed by laser welding, since the laser is light having a single wavelength and no phase difference, it is possible to obtain high-density energy by condensing on an extremely small point with an optical lens. By performing welding using this high-density heat source, high-speed deep penetration welding is possible, and there are advantages such as very little effect of welding heat and little welding deformation. Of course, the influence on the outer frame member 4 can be minimized, and a good appearance can be formed.

  Further, since the inner frame member 2 formed by die casting and the plate-shaped outer frame member 4 formed by pressing are each made of aluminum, they are extremely lightweight and excellent in strength, and The outer frame member 4 can form an appearance utilizing the substrate.

  Therefore, in this embodiment, the outer exposed surface of the inner frame member formed by the die casting method is concealed by the outer frame member formed by the pressing method, so that the productivity is improved, and the thickness and the weight are reduced. It has excellent recyclability, and can be welded efficiently and with minimal effect on the appearance quality. It becomes a housing for equipment.
