Description

Technical Field

[0001] This invention relates to the technical field of electric bicycles, and in particular to a mounting and fixing mechanism, a battery device, and an electric bicycle. Background Technology

[0002] For electric bicycles, to make the battery shape more harmonious and aesthetically pleasing with the overall frame, the battery is usually designed in the shape of a water bottle. A mounting bracket is designed and secured to the downtube of the frame with several screws. The water bottle battery is then mounted on the bracket for easy access during charging. After the battery is mounted on the bracket, for batteries that don't require a lock, a mechanism needs to be designed on the battery casing to cooperate with the battery mounting bracket to secure the battery. This mechanism is usually a plastic clip that requires two hands to operate, resulting in poor ease of installation and removal. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an installation and fixing mechanism, battery device and electric bicycle with better disassembly and assembly convenience.

[0004] The objective of this invention is achieved through the following technical solution:

[0037] This application provides an installation and fixing mechanism including a fixing frame and a fixing kit; the fixing frame includes a fixing frame body and a snap-fit ​​part connected to each other, the snap-fit ​​part having a snap-fit ​​groove; the fixing kit includes a first cover, a cylindrical body and a second cover, the first cover is detachably connected to the fixing frame body and movably connected to the fixing frame body, the two ends of the cylindrical body are respectively connected to the first cover and the second cover to jointly form a battery cavity, the battery cavity being used to accommodate a battery pack; the second cover is provided with a snap-fit ​​pressing mechanism, the snap-fit ​​pressing mechanism being snapped into the snap-fit ​​groove, the snap-fit ​​pressing mechanism being used to separate from the snap-fit ​​groove when subjected to pressure.

[0038] The aforementioned mounting and fixing mechanism allows for easy installation by first attaching the main body of the mounting frame to the bicycle body. Since both ends of the cylinder are connected to the first and second covers respectively, they together form a battery cavity for housing the battery pack. The first cover is detachably connected to the main body of the mounting frame, and when installation is required, the first cover is first attached to the main body of the mounting frame, and then the snap-on pressing mechanism of the second cover is engaged in the slot of the snap-on part, allowing the battery pack to be quickly fixed to the mounting frame via the fixing kit. When disassembly is required, the snap-on pressing mechanism is first pressed, and the second cover is pulled out simultaneously, separating the second cover from the snap-on part. Then, the first cover is removed from the main body of the mounting frame. This allows for one-handed installation and disassembly, improving ease of installation and disassembly.

[0039] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0040] like Figures 1 to 3 As shown, one embodiment of the battery device 10 includes a battery pack 100 and a mounting and fixing mechanism 200. The mounting and fixing mechanism 200 is used to mount and fix the battery pack 100, so that the battery pack 100 is fixedly connected to the bicycle body through the mounting and fixing mechanism 200. In one embodiment, the mounting and fixing mechanism 200 includes a fixing frame 210 and a fixing kit 220. The fixing frame 210 includes a fixing frame body 210a connected to each other and a snap-fit ​​part 210b. The snap-fit ​​part 210b has a snap-fit ​​groove 202. The fixing kit 220 includes a first cover 222, a cylindrical body 224 and a second cover 226. The first cover 222 is detachably connected to the fixing frame body 210a and is movably connected to the fixing frame body 210a so that the first cover 222 can be detached and attached to the fixing frame body 210a. The two ends of the cylindrical body 224 are respectively connected to the first cover 222 and the second cover 226 to form a battery cavity 224a. The battery cavity 224a is used to accommodate the battery pack 100, so that the battery pack 100 is accommodated and fixed in the fixing kit 220. The second cover 226 is provided with a snap-on pressing mechanism 226a, which snaps into the slot 202, so that the second cover 226 is snapped into the snap-on part 210b. The snap-on pressing mechanism 226a is used to separate from the slot 202 when pressure is applied. When the snap-on pressing mechanism 226a is pressed, the snap-on pressing mechanism 226a separates from the slot 202, so that the snap-on pressing mechanism 226a is disassembled from the snap-on part 210b.

[0041] In use, the aforementioned mounting and fixing mechanism 200 can be first installed and connected to the main body 210a of the fixing frame onto the bicycle body. Since both ends of the cylinder 224 are respectively connected to the first cover 222 and the second cover 226 to form a battery cavity 224a for housing the battery pack 100, and since the first cover 222 is detachably connected to the main body 210a of the fixing frame, and the first cover 222 is movably connected to the main body 210a of the fixing frame, when installation is required, the first cover 222 is first connected to the fixing frame. The main body 210a is then attached to the bracket, and the buckle pressing mechanism 226a of the second cover 226 is fastened into the slot 202 of the latching part 210b, so that the battery pack 100 is quickly fixed to the bracket 210 by the fixing kit 220. When disassembly is required, the buckle pressing mechanism 226a is pressed first, and the second cover 226 is pulled out at the same time, so that the second cover 226 is separated from the latching part 210b. Then the first cover 222 is removed from the bracket body 210a. This allows for one-handed disassembly and assembly, improving the convenience of disassembly and assembly.

[0042] In one embodiment, compared to the traditional simple plastic clips or metal spring clips for direct snap-fit ​​installation, the above-mentioned installation and fixing mechanism has a more ingenious structure and a better service life during use.

[0043] like Figure 1 and Figure 4 As shown, where Figure 4 (Not shown) In one embodiment, the two ends of the cylindrical body 224 are respectively fitted onto the first cover 222 and the second cover 226, so that the two ends of the cylindrical body 224 are connected to the first cover 222 and the second cover 226 to form a battery cavity 224a. In this embodiment, both the second cover 226 and the first cover 222 are fitted onto the cylindrical body 224. Further, an annular groove 2222 is formed at the end of the first cover 222, and a locking protrusion 2242 is formed at the end of the cylindrical body 224. The locking protrusion engages with the annular groove 2222, so that the first cover 222 is fitted onto the cylindrical body 224.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment, the first cover 222 is movably fastened to the fixing frame body 210a, making the first cover 222 and the fixing frame body 210a detachably connected, and simultaneously allowing the first cover 222 and the fixing frame body 210a to be movably connected. In one embodiment, the end of the first cover 222 is provided with a fastening conical surface 2224, and the fixing frame body 210a is provided with a conical groove 211 that matches the fastening conical surface, allowing the first cover 222 to be movably fastened to the fixing frame body 210a, while preventing the connection between the first cover 222 and the fixing frame body 210a from jamming during assembly and disassembly.

[0045] In one embodiment, the bevel angle of the snap-fit ​​cone surface is 10° to 20°. In this embodiment, the bevel angle of the snap-fit ​​cone surface is 15°, allowing the first cover 222 to be movably snapped onto the fixing frame body 210a, while preventing the connection between the first cover 222 and the fixing frame body 210a from jamming during assembly and disassembly. It is understood that in other embodiments, the first cover 222 is not limited to being movably snapped onto the fixing frame body 210a.

[0046] like Figures 3 to 6 As shown, in one embodiment, the snap-on pressing mechanism 226a includes a pressing slide 2262, a first fastener 2264, a second fastener 2266, and a first elastic member 2268. The pressing slide is slidably connected to the second cover 226, and the pressing slide is elastically connected to the second cover 226. Both the first fastener and the second fastener are rotatably connected to the second cover 226. See also... Figure 7 and Figure 8 The pressing slide 2262 has a through-hole groove 2261. The inner peripheral wall of the through-hole groove has a narrowing slope 2263 in the direction parallel to the sliding of the pressing slide. The first fastener and the second fastener are both inserted into the through-hole groove and slidably connected to the pressing slide. The two ends of the first elastic member are respectively connected to the first fastener and the second fastener, so that the two ends of the first elastic member can better elastically abut against the first fastener and the second fastener. In this embodiment, both the first fastener and the second fastener have countersunk grooves. The two ends of the first elastic member abut against the countersunk grooves of the first fastener and the second fastener, so that the two ends of the first elastic member can better elastically abut against the first fastener and the second fastener. In one embodiment, the through-hole groove is trapezoidal or triangular in shape.

[0047] like Figure 3 and Figure 5 As shown, the second cover 226 further includes a recessed groove 2265, where portions of the first and second fasteners are located. The engaging portion 210b is located within the recessed groove and engages with the second cover 226. The distance between the first and second fasteners within the recessed groove changes as the pressing slide slides relative to the second cover 226. During the sliding of the pressing slide relative to the second cover 226, the distance between the first and second fasteners within the recessed groove gradually decreases or increases, causing a change in the compression of the first elastic element. In this embodiment, the first elastic element 2268 can be a coil spring or an elastic rubber block.

[0048] like Figure 9As shown, the second cover 226 further includes a press-to-hold handle 2266 and a handle base 2277 connected together. A recessed groove 2265 is formed in the handle base 2277. A press-to-hold slide is slidably connected to the press-to-hold handle 2266, allowing the press-to-hold slide to be slidably connected to the second cover 226. In this embodiment, the handle base 2277 is sleeved on the cylinder 224. In this embodiment, the press-to-hold handle 2266 and the handle base 2277 are detachably connected to facilitate the assembly of the mounting and fixing mechanism 200. Further, the second cover 226 also includes fixing screws 226c. The press-to-hold handle 2266 has a connecting through hole 2266a, and the handle base 2277 has a fixing screw hole 2277a. The fixing screws are respectively inserted into the connecting through hole and the fixing screw hole, allowing the press-to-hold handle 2266 and the handle base 2277 to be detachably connected. It is understood that in other embodiments, the press handle 2266 and the handle base 2277 are not limited to being fixedly connected by fixing screws, but can also be connected by snap-fit. In this embodiment, the fixing screw is a Torx screw.

[0049] In one embodiment, the first elastic element is disposed between the first fastener and the second fastener, making the snap-fit ​​pressing mechanism 226a more compact, while also providing better elasticity between the first fastener and the second fastener. And / or, as... Figure 5 , Figure 8 and Figure 9 As shown, in one embodiment, the distance between the first fastener 2264 and the second fastener 2266 in the recess is designed to gradually decrease as the pressing slide slides relative to the second cover 226 in a direction away from the first cover 222. That is, when the pressing slide is pressed, it slides relative to the second cover 226 in a direction away from the first cover 222, i.e., the pressing slide slides relative to the second cover 226 in the D direction. At this time, the distance between the first fastener and the second fastener in the recess gradually decreases, allowing the snap-on pressing mechanism 226a to separate from the snap-on slot 202. Conversely, when the pressing slide is released, it slides relative to the second cover 226 in a direction closer to the first cover 222 under the elastic restoring action of the second elastic member 2269, i.e., the pressing slide slides relative to the second cover 226 in the C direction. The distance between the first fastener and the second fastener in the recess gradually increases.

[0050] like Figure 6 , Figure 8 and Figure 9As shown, in one embodiment, the second cover 226 further has a sliding groove 2267 communicating with the clearance groove 2265. The pressing slide is located in the sliding groove and is slidably connected to the second cover 226, allowing for better sliding connection between the pressing slide and the second cover 226. And / or, in one embodiment, the snap-on pressing mechanism 226a further includes a second elastic member 2269. Both ends of the second elastic member are respectively connected to the pressing slide and the second cover 226, allowing the pressing slide to be elastically slidably connected to the second cover 226. In this embodiment, one end of the second elastic member is fixedly connected to the inner wall of the sliding groove, allowing the second elastic member to be received within the sliding groove. In this embodiment, the second elastic member can be a coil spring or an elastic rubber block.

[0051] like Figure 5 and Figure 6 As shown, in one embodiment, the second cover 226 has a pass groove 2271, and the pressing slide 2262 has a pressing groove 2272. The pressing groove communicates with the pass groove, giving the second cover 226 a handle portion. This allows for pressing the pressing slide through the pass groove and pressing groove, improving the ease of use of the mounting and fixing mechanism 200. In this embodiment, the sliding groove also communicates with the pass groove. Furthermore, the pressing slide 2262 has a receiving groove 2273. The other end of the second elastic member is located within the receiving groove and connected to the pressing slide, allowing the second elastic member to be better fixedly connected to the pressing slide. In this embodiment, the inner wall of the receiving groove 2273 has a mounting protrusion 2274. One end of the second elastic member is sleeved on the mounting protrusion, allowing the second elastic member to be better connected to the pressing slide, while also providing better guidance for the pressing slide during its sliding relative to the second cover 226. The inner peripheral wall of the sliding groove is formed with a positioning groove, and the other end of the second elastic member is located in the positioning groove and abuts against the second cover 226. Furthermore, the pressing slide has a rounded transition at the opening where the receiving groove is formed, which avoids the pressing slide from getting stuck during the sliding process in the sliding groove, and at the same time reduces the resistance between the pressing slide and the second cover 226 during the sliding process.

[0052] like Figure 6 and Figure 9As shown, further, the first fastener 2264 has a first sliding groove 2275, the second fastener 2266 has a second sliding groove 2276, and the pressing slide has a sliding plate portion. A through-hole groove is formed in the sliding plate portion. The sliding plate portion is located in the first sliding groove and is slidably connected to the first fastener. The sliding plate portion is located in the second sliding groove and is slidably connected to the second fastener, so that the pressing slide is slidably connected to the first fastener and the second fastener respectively. Furthermore, the portion of the first fastener that slides in contact with the pressing slide has a first arc-shaped surface, allowing for better slidable connection between the first fastener and the sliding plate portion. Furthermore, the portion of the second fastener that slides in contact with the pressing slide has a second arc-shaped surface, allowing for better slidable connection between the second fastener and the sliding plate portion.

[0053] Furthermore, the first fastener has a first latching portion, and the second fastener has a second latching portion. Both the first and second latching portions are located within the clearance groove, and the distance between the first and second latching portions varies depending on the relative sliding position of the pressing slide and the second cover 226, so that the latching pressing mechanism 226a engages within the latching groove 202. In this embodiment, the first latching portion forms a first latching groove, and the second latching portion forms a second latching groove. When the latching pressing mechanism 226a engages within the latching groove 202, the inner peripheral wall of the latching groove 202 is limited to the first and second latching grooves. Specifically, the first and second latching grooves are arranged opposite to each other. In one embodiment, both the first and second latching portions are metal fasteners, giving both the first and second latching portions good wear resistance, thus improving the wear resistance of the latching pressing mechanism 226a.

[0054] Furthermore, both the connection points between the first fastener and the second cover 226 and the connection points between the second fastener and the second cover 226 have arc-shaped transition portions, allowing both the first and second fasteners to be rotatably connected to the second cover 226. In this embodiment, the arc-shaped transition portions all have protruding arc-shaped surfaces, reducing the resistance encountered by the arc-shaped transition portions during rotation relative to the second cover 226. In one embodiment, the mounting and fixing mechanism 200 also includes a locking member. The second cover 226 has a through hole, and the arc-shaped transition portion has a positioning hole. Positioning pins are respectively inserted into the through hole and the positioning hole, allowing the arc-shaped transition portion to be rotatably connected to the second cover 226. In this embodiment, when the handle is pulled upwards, the metal buckle rotates around the positioning pin, retracts towards the center along the inclined side of the trapezoidal hole of the handle, and disengages from the buckle on the fixing frame 210.

[0055] like Figure 9 and Figure 10As shown, the snap-fit ​​pressing mechanism 226a further includes a snap-fit ​​hook 2279. The snap-fit ​​hook is located in the recess and installed on the handle base 2277, and is located on the same side of the first fastener and the second fastener, so as to limit the first fastener and the second fastener, so that the first fastener and the second fastener are reliably aligned, and thus the two ends of the first elastic member reliably and elastically abut against the first fastener and the second fastener. In this embodiment, the snap-fit ​​hook is locked to the handle base 2277 by screws. In this embodiment, the snap-fit ​​hook 2279 is installed on the inner side wall of the recess. Specifically, the inner side wall of the recess has a positioning groove, and the snap-fit ​​hook is located in the positioning groove and fixedly connected to the handle base.

[0056] In one embodiment, during assembly of the battery device 10, the fixing kit 220 is first assembled, and the two metal buckles with their beveled surfaces facing upwards are inserted into the handle of the second cover 226. The first elastic element is then inserted into the recess between the two metal buckles. The aforementioned parts are then inserted into the second cover 226 together. Two fixing pins are then inserted into the through holes of the metal buckles, and a Phillips head countersunk screw is used to lock the buckle hook onto the spring side of the second cover 226, thereby fixing the metal buckle to the second cover 226. Next, the battery pack 100 is placed into the cylinder 224 from the bottom, the connecting wires are connected, and the first cover 222 and the second cover 226 are locked. Then, the aligned holes of the processed second cover 226 are placed on the upper surface of the cylinder 224, the second elastic element is aligned and placed on the second cover 226, and the pressing slide is installed on the second cover 226. The cover is then pressed down by hand, and Torx screws are tightened into the multiple holes on the handle of the second cover 226. At this point, the handle cover is fixed to the cylinder 224. Next, align the handle decorative cover with the buckle and install it onto the handle cover, completing the assembly of the battery device 10. Then, first, tilt one side of the assembled battery device 10 into the groove of the fixing bracket 210. Then, pull the handle of the second cover 226 while simultaneously placing the entire battery device 10 onto the fixing bracket 210. After releasing the handle, the metal buckle engages with the buckle of the locking part 210b of the fixing bracket 210, thus fixing the battery device 10 onto the electric bicycle. Conversely, to remove the battery device 10, press down on the pressing slide and pull upwards on the second cover 226 to remove the battery device 10.

[0057] This application also provides an electric bicycle, including a bicycle body and the aforementioned battery device 10, wherein the mounting frame body 210a is fixedly connected to the bicycle body. Further, the battery device 10 includes a battery pack 100 and a mounting and fixing mechanism 200, which is used to mount and fix the battery pack 100, so that the battery pack 100 is fixedly connected to the bicycle body via the mounting and fixing mechanism 200. In one embodiment, the mounting and fixing mechanism 200 includes a fixing frame 210 and a fixing kit 220. The fixing frame 210 includes a connected fixing frame body 210a and a snap-fit ​​portion 210b, the snap-fit ​​portion 210b having a snap-fit ​​groove 202; the fixing kit 220 includes a first cover 222, a cylindrical body 224, and a second cover 226, the first cover 222 being detachably connected to the fixing frame body 210a, and the first cover 222 being movably connected to the fixing frame body 210a, so that the first cover 222 can be detached and attached to the fixing frame body 210a. The two ends of the cylindrical body 224 are respectively connected to the first cover 222 and the second cover 226 to form a battery cavity 224a. The battery cavity 224a is used to accommodate the battery pack 100, so that the battery pack 100 is accommodated and fixed in the fixing kit 220. The second cover 226 is provided with a snap-on pressing mechanism 226a, which snaps into the slot 202, so that the second cover 226 is snapped into the snap-on part 210b. The snap-on pressing mechanism 226a is used to separate from the slot 202 when pressure is applied. When the snap-on pressing mechanism 226a is pressed, the snap-on pressing mechanism 226a separates from the slot 202, so that the snap-on pressing mechanism 226a is disassembled from the snap-on part 210b.

[0058] In use, the aforementioned mounting and fixing mechanism 200 can be first installed and connected to the main body 210a of the fixing frame onto the bicycle body. Since both ends of the cylinder 224 are respectively connected to the first cover 222 and the second cover 226 to form a battery cavity 224a for housing the battery pack 100, and since the first cover 222 is detachably connected to the main body 210a of the fixing frame, and the first cover 222 is movably connected to the main body 210a of the fixing frame, when installation is required, the first cover 222 is first connected to the fixing frame.
