## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a sliding module, and more particularly to a sliding module that connects a tension spring and a spindle plate to two modules respectively, so that the two modules can slide with respect to each other. If the sliding modules are coupled to the upper and lower modules respectively, the two modules can be stacked with each other or pulled from each other. Further, the sliding module is connected to an axle structure, such that the upper module has the multi-directional pivotal rotating, idling and positioning functions.
2. Description of the Related Art
Sliding modules are used extensively in our life, and a drawer is one of the common examples, and sliding modules substitute a lift-and-close mode. Two modules are shifted, so that the two modules are stacked with each other or pulled away from each other. For example, a clamshell mobile phone adopts a cover that can be lifted open or closed with respect to its lower base by a spindle mode or a hinge mode.
With the unceasing developments made by manufacturers, sliding modules have been applied to various different objects having a cover, such as a slider set mobile phone having an upper cover stacked onto a base at an operating mode or the upper cover covering an operating panel at a closing mode, but if the upper cover is slid and pulled, then the operating panel is exposed at an operating mode. Of course, the upper cover can be pulled to selectively cover the operating panel at the closing mode and stacking the upper cover onto the operating panel at the operating mode.
Besides the basic pulling and stacking functions of the aforementioned sliding module, the sliding module can be slid automatically. In other words, when the upper cover is slid to a specific position, the upper cover will keep on sliding automatically without requiring users to manually pull the cover all the way to the end of the traveling path, and thus making the application more convenient.
Further, digital capturing devices such as digital cameras and digital camcorders have changed our way of taking pictures or recording video films. Basically, the digital capturing devices of this sort usually come with a small display screen on the casing of the devices for facilitating viewing and browsing the pictures or films. Preferably, the casing and the display screen include a spindle such that the display screen can be opened or shut or even can be revolved in a larger angle. At present, mobile phones tend to integrate with a digital capturing device, and these spindle structures are used extensively for the folding mobile phones such as the NOKIA 6260 smart phones, but such sliding structures have never been used in the slider set mobile phones yet, and thus the application of the sliding modules has been restricted significantly, and further improvements are needed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The structure, technical measures and effects of the present invention will now be described in more detail hereinafter with reference to the accompanying drawings that show various embodiments of the invention.
Referring to FIGS. 1 to 3, the sliding module of the present invention is an improvement over R.O.C. Pat. Application No. 094206238 (which is a counterpart of P.R.C. Pat. Application No. 200520011854.6), the aforementioned methods are merged into the present invention, and the present invention comprises a sliding member 1, a spindle member 2, a tension spring 3 and a slid member 4. Further the top of the slid member 4 is coupled to an axle structure 5.
The sliding member 1 is a substantially a H-shape plate body having a rectangular sliding plate 11 disposed on both sides of the sliding member 1, and the external side of the sliding plate 11 is bent internally into a curved shape, but it is a prior art and thus will not be described here. A transversal plate 12 is fixed transversally and substantially in the middle of the two sliding plates 11, and a lateral side of the transversal plate 12 includes a rectangular penetrating transversal groove 121. Further, the sliding plate 11 at an external side of the transversal groove 121 includes a through hole 111, such that the sliding member 1 can be connected to an object such as a lower module. The sliding plate 11 includes a plurality of positioning holes 112, but it is a prior art and thus will not be described here.
The spindle member 2 is a rectangular spindle plate 21 and includes a spindle hole 2 disposed separately on both sides of the spindle member 2, and a spindle bolt 23a, 23b passes through one of the spindle holes 22 of the spindle plate 21 and is coupled to the transversal groove 121 by the spindle bolt 23a or could be in a sliding state, and another end of the spindle hole 22 could be another spindle bolt 23b passing through the slid member 4 and being connected to the slid member 4. In practice applications, the top of the spindle bolt 23a includes a bolt aperture 231, and another spindle bolt 23b can install a washer 232.
The tension spring 3 is a resilient member. Unlike the aforementioned patented inventions, both ends of the tension spring 3 are bent into a spring hook 31. Two spring hooks 32 are latched respectively into the through hole 111 and the bolt aperture 231 for defining a positioning relation.
The slid member 4 is a driven plate 41 having a bent sliding groove 42 disposed on both lateral sides of the slid member 4 and having a size large enough to accommodate the external end of the sliding plate 11 for providing an embedment with a sliding state. The spindle bolt 23b is used for coupling the slid member 4 with the spindle member 2, and the driven plate 41 includes a plate aperture 43. In the meanwhile, each corner of the driver plate 41 has a plurality of fixing holes 44 for connecting an object such as an upper module.
Referring to FIG. 3, two spring hooks 31 of the invention are latched into the bolt aperture 231 and the through hole 111 respectively, and the spindle bolt 23a passes through the spindle hole 22 of the spindle plate 21 and the transversal groove 121 for a connection, and the slid member 4 is embedded into the external position of the two sliding plates 11 by its sliding groove 42. In the meantime, the spindle bolt 23b passes through another spindle hole 22 of the spindle plate 21, the washer 232 and the plate aperture 43 for its positioning, so that the sliding member 1 is connected to a lower module such as a base, and the slid member 4 is connected to an upper module such as a cover, or vice versa. Therefore, the cover can be slid with respect to the base. For example, the slid member 4 is at an operating state when the slid member 4 is extended outward from the sliding member 1. If a force is applied to the slid member 4 in an opposite direction, the slid member 4 will be set to a closing state.
The principle of operation of the present invention resides on that when the slid member 4 is pushed outward, the tension spring 3 is compressed by the rotation of the spindle member 2 to store energy, and the slid member 4 is stacked on the sliding member 1, and thus an end of the spindle member 2 situated at the transversal groove 121 together with a lateral side of the spindle bolt 23a move outward along the transversal groove 121. When the spindle member 2 is moved to the utmost external side, an equilibrium state is accomplished, and then the tension spring 3 stores its maximum energy. If a force is applied, the tension spring 3 will release energy to extend and drive the spindle bolt 23a of the spindle member 2 to move along the internal side of the transversal groove 121, and thus will drive the slid member 4 to extend out from the sliding member 1, and if such arrangement is applied to an object, then an operating state can be achieved.
On the other hand, if it is necessary to cover the sliding member 1 and the slid member 4 is pushed inward to half of the traveling path, the slid member 4 will be extended outward by the released energy of the tension spring 3. If such arrangement is applied to an object, then a closing state can be achieved.
Referring to FIGS. 1 to 5, the slid member 4 of the sliding module further comprises an axle structure 5 for achieving the sliding function as well as the multi-directional pivotal rotating, idling and positioning functions, wherein the external edge of the slid member 4 includes a rectangular board indent 45 and a connecting portion 46 disposed separately on both sides of the board indent 45 as shown in the figure, and the connecting portions 46 are substantially an L-shape frame.
The axle structure 5 is disposed at the top of the slid member 4 and comprises a first pivotal axle 51 and a second pivotal axle 52 disposed vertically and parallelly with said slid member 4.
The first pivotal axle 51 is a stand board 511 coupled to a connecting frame 46 disposed on both sides of the board indent 45, and an axle pillar 512 passes through at least a resilient member 513, a spacer 514, a spindle hole 511a of the stand board 511 and a stand hole 515a of a support stand 515, and an end of the axle pillar 512 is pivotally coupled to connect the foregoing elements as a whole and provide the function of a pivotal axle. The support stand 515 can be rotated by external forces and having a limited angle of rotation, and a stop latch 511b and a pushing latch 515b are installed coaxially and alternately at the periphery of the spindle hole 511a and the stand hole 515a, and a limit plate 516 is installed between the stand board 511 and the support stand 515, of which an axle pillar 512 is passed and a pushing flange 516a and a stop flange 516b are protruded according to a rotary angle. If the support stand 515 is rotated, the pushing latch 515b will push the pushing flange 516a, until the stop flange 516b presses on the stop latch 511b as shown in the figure, and the pushing flange 516a and the stop flange 516b are installed at 180 degree with respect to each other.
The second pivotal axle 52 has an end of a pillar 521 connected to a vertical branch hole 515c of the support stand 515 and another end of the pillar 521 passing through a plate aperture 522a of a connecting board 522, at least one resilient member 523 and a spacer 524, and then an end of the pillar 521 is riveted, so that the foregoing components are connected as a whole to provide the function of a pivotal axle, wherein the resilient member 513, 523 could be a spring, a wavy bracket or a disc bracket. To provide a limited angle of rotation for the connecting board 522, a fixing plate 525 is installed between the pillar 521 and the connecting board 522 for passing the pillar 521 and fixing the pillar 521 thereon as shown in the figure. Two connecting plates 525a are protruded from the fixing plate 525 and connected to the pillar 521 with a fixed state. Further, at least one stop flange 525b is protruded from the periphery of the fixing plate 525, and a stop tenon 522b is protruded from the periphery of the plate aperture 522a at the bottom surface of the connecting plate 522. If the connecting plate 522 is rotated, the stop tenon 522b is in contact with the stop flange 525b for stopping the rotation. Further, the invention comes with a significant touch of a height difference during its operation. At least one plate protrusion 522c is protruded from the periphery of the plate aperture 522a, and at least one groove 525c is disposed at the corresponding surface of the fixing plate 525, such that if the connecting plate 522 is rotated, the plate protrusion 522c is rotated synchronously, and thus producing a significant touch of height difference when the plate protrusion 522c falls into the groove 525c. 
With the implementation of the present invention, the sliding module can be operated more conveniently by the energy storage and release of the tension spring. In other words, a user needs not to push the sliding member all the way but just to a half way of the traveling path for an automatic extension or closing. Further, the top of the slid member of the sliding module includes an axle structure having a first pivotal axle disposed vertically with the axle structure and a second pivotal axle disposed horizontally with the axle structure. When the sliding module is coupled separately to an upper module and a lower module, the upper and lower modules will be stacked with each other or pulled away from each other. Further, the upper module is divided into a left module and a right module. If the base has an operating portion of the lower module coupled with the sliding member and the left module of the upper module installs a slid member, and the right module is coupled to the second pivotal axle, and the left module has a menu portion and the right module has a display portion, the right module can be turned forward or backward to an angle of 180 degrees and rotated freely thereon during the operation, such that the right module of the upper module provides the multi-directional pivotal rotating, idling and positioning functions. The present invention is definitely a novel breakthrough of the sliding module.
The present invention provides a feasible solution, and a patent application is duly filed accordingly. However, it is to be noted that the preferred embodiments disclosed in the specification and the accompanying drawings are not intended to limit the invention. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and thus the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
