DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] The technical contents of this disclosure will become apparent with the detailed description of preferred embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than restrictive.
[0022] With reference to FIGS. 1 to 3 for a switch of a battery, the switch 1 comprises a knob 2, a cap 3, a cam 4 and a base 5, wherein the knob 2 has a shaft 21 formed therein and a lug 211 disposed on both sides of the shaft 21 separately; the cap 3 has a containing space 31 formed therein and a slot 32 formed on the exterior of the cap 3 and in a shape corresponsive to the shaft 21 and the lug 211 of the knob 2 and provided for passing the shaft 21 and the lug 211 of the knob 2 of the cap 3; the cam 4 is installed in the containing space 31 of the cap 3, and the external periphery of the cam has two first planes 41, two second planes 42 and two inclined planes 43 coupled to the first plane 41 and the second plane 42 and corresponsive to one another, and the first plane 41, the second plane 42 and the inclined plane 43 are provided for sliding and moving the lug 211 of the knob 2, and a metal plate 44 is installed at the bottom of the cam 4, and a first elastic member 45 is installed between the cam 4 and the metal plate 44, and the metal plate 44 has two first contact points 441 formed thereon, wherein the first elastic member 45 of an embodiment of the present invention is a spring; and the base 5 is for containing cam 4, and the base 5 has two second contact points 51 formed therein, and a second elastic member 52 is installed between the base 5 and the cam 4, and two terminal columns 53 are formed at the bottom of the base 5, wherein the second elastic member 52 of an embodiment of the present invention is a spring.
[0023] In an embodiment of the present invention as shown in FIGS. 2-3, the cap 3 has two openings 33 formed on the outer side of the cap 3, and at least one arc column 34 is formed in the containing space 31, and the external periphery of the cam 4 has at least one arc groove 46 corresponsive to the arc column 34, and the outer side of the base 5 has two bumps 54 corresponsive to the opening 33 of the cap 3. In assembling, the shaft 21 and the lug 211 of the knob 2 are movably passed into the slot 32 of the cap 3, and the arc groove 46 of the cam 4 and the arc column 34 of the cap 3 are embedded and engaged with each other, so that the cam 4 is disposed in the containing space 31 of the cap 3, and the lug 211 of the knob 2 abuts the position of the first plane 41, the second plane 42 or the inclined plane 43 of the cam 4, and the base 5 is plugged into the containing space 31 of cap 3, and the bump 54 of the base 5 is embedded and fixed into the opening 33 of the cap 3.
[0024] With reference to FIGS. 4-A to 4-B for setting the battery at an OFF state, the knob 2 of the switch 1 is turned to an “OFF” position of the cap 3 as shown in FIG. 5. Now, the shaft 21 and the lug 211 of the knob 2 are not configured to be corresponsive to the position of the slot 32 of the cap 3 and are disposed on the two inclined planes 43 of the cam 4. Due to the elastic restoring force of the first elastic member 45 and the second elastic member 52, a gap is formed between the first contact point 441 of the cam 4 and the second contact point 51 of the base 5 as shown in FIG. 5, so that the switch 1 is situated at an OFF state.
[0025] With reference to FIGS. 6-A and 6-B for setting the battery to an ON state, the knob 2 of the switch 1 is turned to an ON position of the cap 3 as shown in FIG. 7. Now, the shaft 21 and the lug 211 of the knob 2 are not configured to be corresponsive to the position of the slot 32 of the cap 3 and are disposed on the two first planes 41 of the cam 4 (and at the highest point of the cam 4), so that the first elastic member 45 and the second elastic member 52 are compressed since the cam 4 is pressed down by the lug 211 of the knob 2, and the first contact point 441 of the cam 4 and the second contact point 51 of the base 5 are contacted with each other (as shown in FIG. 5), so that the switch 1 is situated at an ON state.
[0026] With reference to FIGS. 8-A, 8-B and 9 for using the battery with an anti-theft function, the knob 2 of the switch 1 is turned to an OUT position of the cap 3. Now, the shaft 21 and the lug 211 of the knob 2 are configured to be corresponsive to the position of the slot 32 of the cap 3 and disposed on the two second planes 42 of the cam 4, so that the shaft 21 and the lug 211 of the knob 2 can be removed from the slot 32 of the cap 3, and the switch 1 is lack of the knob 2 and cannot be operated. In addition, the switched 1 is switched to the OFF state.
[0027] With reference to FIG. 10 for another embodiment of the present invention, when it is not necessary to use the switch 1 for the anti-theft purpose, then the cam 4 may have a cylinder 47 installed on one of the second planes 42, such that after the knob 2 is installed to the cap 3 and when it is necessary to turn the knob 2 to move the two lugs 211 to the second plane 42 (as shown in FIGS. 11-A and 11-B), the lug 211 is blocked by the cylinder 47 and cannot be moved, so that the knob 2 cannot be removed from the cap 3 in order to prevent the knob 2 from missing or lost.
[0028] By movably passing the shaft 21 of the knob 2 into the slot 32 of the cap 3 and placing the shaft 21 onto the first plane 41, the second plane 42, or the inclined plane 43 of the cam 4, the knob 2 may be turned according to a user requirement, so that the lug 211 of the knob 2 may be slid and moved to the first plane 41, the inclined plane 43, or the second plane 42 to achieve the effects of connecting or disconnecting the battery or preventing any unauthorized removal of the knob 2. When the anti-theft function is not needed, the second plane 42 of the cam 4 may have a cylinder 47 installed thereon, so that the lug 211 of the knob 2 is blocked by the cylinder 47 and cannot be configured to be corresponsive to the slot 32 of the cap 3 to achieve the effect of preventing the knob 2 from missing or being lost.
[0029] While this disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of this disclosure set forth in the claims.
