Safety protection devices for locomotives

Abstract

A safety protection device for a motorcycle includes a pressing mechanism mounted on a frame and located on one side of a battery, and a conducting mechanism mounted on a rocker arm and facing the battery. The pressing mechanism includes a rocker arm operable to swing between a released position and a fixed position relative to the frame. When the rocker arm swings to the released position, the rocker arm and the conducting mechanism do not contact the battery. When the rocker arm swings to the fixed position, it presses against and secures the battery, and the conducting mechanism contacts the battery, forming a conductive path connecting the battery and the frame. In the event of accidental battery leakage, the conducting mechanism can directly conduct the leakage to the frame, thereby preventing electric shock. Furthermore, securing the battery and grounding the battery can be completed simultaneously in a single operation, reducing operational complexity.

[0016] [Effects of the Invention]

[0017] The advantages of this invention are as follows: In practical design, the rocker arm can be activated by closing the seat cushion or other operating methods, causing it to swing from the released position to the fixed position, thereby pressing and securing the at least one battery. At this time, the conductive mechanism also contacts the at least one battery. If the at least one battery accidentally leaks electricity, the conductive mechanism can directly conduct the leakage to the vehicle frame, thus preventing electric shock. Furthermore, securing the battery and grounding can be completed simultaneously in a single operation, reducing operational complexity.

[0018] In some embodiments of the present invention, the advantage is that the compression spring can push the conduction mechanism outward so that the conduction mechanism can reliably contact the at least one battery, thereby eliminating the influence of tolerance or the contour of the outer surface of the at least one battery.

[0019] In some embodiments of the present invention, the advantage is that the limiting plates can restrict the displacement direction of the sliding member and prevent the transmission mechanism and the pressing mechanism from interfering with each other.

[0020] In some embodiments of the present invention, the advantage is that when the cover portion presses against the at least one battery, the elastic block portion can ensure that the cover portion has a large area to abut against the at least one battery, thereby maximizing the contact area and enabling smooth conduction.

[0021] In some embodiments of the present invention, the advantage is that some batteries will indicate information by forming specific words or patterns in an etched area on the insulating outer layer. Therefore, by touching the etched area with the cover, the user can avoid being shocked by accident when the at least one battery is leaking.

[0022] In some embodiments of the present invention, the advantage is that, by designing the guide and the compression spring between the conductive elements, the conductive elements can apply pressure evenly to the at least one battery.

Implementation

[0025] Referring to Figures 1 to 4, one embodiment of the safety protection device for a motorcycle 1 of the present invention is shown. The motorcycle 1 includes a body frame 11 forming a battery slot 111, and two batteries 12 removably inserted into the battery slot 111. Each battery 12 includes a housing 121 and a handle 122 generally curved and connected at both ends to the housing 121, made of a non-conductive material. It should be noted that the number of batteries 12 is not limited to two; it can also be one or other numbers. The safety protection device includes a pressing mechanism 2 disposed on the body frame 11 and located within the battery slot 111, and located on one side of the batteries 12; an adjusting mechanism 3 disposed on the pressing mechanism 2; and a conducting mechanism 4 movably disposed on the pressing mechanism 2 by the adjusting mechanism 3.

[0026] Referring to Figures 3, 4, and 5, the pressing mechanism 2 includes a base 21 that defines a limiting groove 211 and is detachably mounted on the vehicle frame 11 and located in the battery slot 111; a pivot 22 that horizontally passes through the base 21 and through the limiting groove 211; a rocker arm 23 that is partially located in the limiting groove 211 and passes through the pivot 22; a torsion spring 24 that is mounted on the pivot 22 and located in the limiting groove 211, with its two ends respectively pushing against the base 21 and the rocker arm 23; and two limiting pieces 25 that protrude from the rocker arm 23 toward the batteries 12 and are spaced apart from each other vertically. The rocker arm 23 has a main body 231 and a buffer member 232 that is detachably mounted on the main body 231. The main body 231 has two pivot portions 233 spaced apart from each other in the limiting groove 211 and passed through by the pivot 22; an extension portion 234 connecting the pivot portions 233 and extending upward out of the limiting groove 211 and integrally connected to the limiting pieces 25; and a bent portion 235 extending from the extension portion 234 and parallel to the limiting pieces 25. The buffer member 232 is fixed to the bent portion 235 by embedding or other means, and is mostly located below the bent portion 235, while also partially located above it. The buffer member 232 is made of a non-conductive material, preferably with shock absorption and elasticity, to improve the effect of suppression and reduce noise.

[0027] Referring to Figures 4, 5, and 6, the adjustment mechanism 3 includes a guide member 31 extending toward the batteries 12 and passing through the extension plate 234 and the conduction mechanism 4; a compression spring 32 mounted on the guide member 31 with its two ends respectively abutting against the extension plate 234 and the conduction mechanism 4; and a fixing member 33 fixed to the guide member 31 and located outside the conduction mechanism 4. The central axis of the guide member 31 extends generally between the two batteries 12 (see Figure 1), but in actual design, the number of batteries 12 is taken into consideration and is not limited to the above. The guide member 31 passes through the limiting plates 25, and the compression spring 32 is located between the limiting plates 25. The fixing member 33 can be an E-ring or a nut. The conduction mechanism 4 includes a sliding member 41 through which the guide member 31 passes and whose extension direction is perpendicular to the extension direction of the guide member 31, and two conduction members 42 disposed at intervals on the sliding member 41. The sliding member 41 is confined between the limiting pieces 25 and is abutted by the compression spring 32. The guide member 31 passes through the center of the sliding member 41, and the conduction members 42 are respectively located at opposite ends of the sliding member 41. Each conduction member 42 has a block portion 421 made of elastic material and a cover portion 422 made of conductive material covering the block portion 421. In this embodiment, the block portion 421 is ethylene propylene diene monomer (EPDM), the cover portion 422 is copper foil tape, the cover portion 422 covers the block portion 421, and the cover portion 422 is bound to the sliding member 41 through two metal wires A. The above material selection and fixing methods are only examples and should not be taken as a limit in practice.

[0028] Referring to Figures 1, 3, and 6, the rocker arm 23 can be operated to swing between a released position and a fixed position relative to the vehicle frame 11. The operation is usually triggered by opening or closing the seat cushion. When the user opens the seat cushion, the torsion spring 24 (see Figure 4) positions the rocker arm 23 in the released position as shown in Figure 6. At this time, the buffer 232 does not contact the batteries 12, and the cover 422 does not contact the batteries 12. In the released position, the sliding member 41 is pushed outward by the compression spring 32 to abut against the fixed member 33. When the user closes the seat cushion, the cushion presses down on the portion of the cushion 232 above the bent portion 235, causing the rocker arm 23 to swing toward the batteries 12 to the fixed position shown in Figure 3. At this time, the portion of the cushion 232 below the bent portion 235 simultaneously presses down on the casing 121 of the batteries 12, thereby fixing the batteries 12 in the battery slot 111. At the same time, the covers 422 contact the batteries 12 respectively, so that each cover 422 forms a conductive path connecting the corresponding battery 12 and the vehicle frame 11. In this way, if any battery 12 accidentally leaks current, the current can be guided to the vehicle frame 11 through the corresponding conductive path. In this fixed position, due to the reaction force of the covering portions 422 pushing against the batteries 12, the sliding member 41 moves towards the extension portion 234 and compresses the compression spring 32. The elasticity provided by the compression spring 32 and the elasticity of the block portions 421 ensure that the covering portions 422 can be evenly pressed onto the batteries 12 and maintain the maximum contact area to ensure smooth conductivity. The sliding member 41 is restricted in direction by the limiting pieces 25 when it moves, thereby preventing the conduction mechanism 4 from interfering with the pressing mechanism 2.

[0029] It should be noted that a typical battery 12 usually has an insulating outer layer B on its casing 121, and an etched area C exposed on the insulating outer layer B but not insulated. This etched area C often forms specific lettering or patterns to indicate information. When the rocker arm 23 is in the fixed position, each cover portion 422 contacts the corresponding etched area C of the battery 12 to prevent the user from accidentally touching the etched area C and experiencing an electric shock if the battery 12 leaks current. Furthermore, both the base 21 and the buffer 232 are detachable, facilitating modularization for easy assembly and replacement / repair. The buffer 232 also absorbs shock when fixing the batteries 12, reducing noise generated when impacting them. Simultaneously, both the buffer 232 and the handle 122 are insulated to prevent leakage current from being conducted to the human body.

[0030] In summary, in practical design, the rocker arm 23 can be activated by closing the seat cushion or other operating methods, causing it to swing from the released position to the fixed position, thereby pressing and fixing the batteries 12. At this time, the covers 422 respectively contact the batteries 12. If any battery 12 accidentally leaks electricity, the corresponding cover 422 can directly conduct the leakage to the vehicle frame 11, thereby preventing electric shock. Furthermore, fixing the batteries 12 and completing the grounding function can be completed simultaneously in a single operation, reducing operational complexity and thus effectively achieving the purpose of the invention.

Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the patent specification shall still fall within the scope of the patent of the present invention.
