Description

Technical Field

[0001] This invention belongs to the field of personal transportation technology, specifically referring to an electric scooter and its battery mounting mechanism. Background Technology

[0002] Electric scooters are a new type of transportation tool, popular among users due to their convenient riding, compact size, and portability. Traditional electric scooters typically include a frame, front and rear wheels, a battery pack, a controller, and handlebars. The battery pack is detachably fixed inside the hollow frame, and its power plug is connected to a power socket inside the frame.

[0003] Sometimes, when vehicles are driving on roads with complex conditions, they may experience a sudden loss of power. One reason for this is that the vehicle design lacks a reliable battery pack securing structure. Bumpy roads can cause the battery pack to shift due to vibration, leading to poor contact between the power plug and the power socket, resulting in a power outage. To improve this issue, a limiting and securing structure for the battery pack is often added inside the vehicle frame. While this solves the problem, it also makes the installation and removal of the battery pack more cumbersome.

[0004] Content of this invention

[0005] The purpose of this invention is to provide an electric scooter and its battery mounting mechanism that are simple in structure, easy to install and remove the battery, and stable in fixation.

[0006] The objective of this invention is achieved as follows:

[0007] A battery mounting mechanism, comprising:

[0008] The frame contains a battery mounting compartment and a power connection point.

[0009] A power mounting plate is located at the bottom of the battery mounting compartment and has a battery mounting slot.

[0010] A battery pack is installed in the battery mounting slot and connected to the power connection part;

[0011] The upper and lower limit unit has a slot portion disposed on the power mounting plate and a block portion disposed on the battery pack; and

[0012] The front and rear limiting unit has a slot portion provided on the power mounting plate and a pin assembly provided on the battery pack;

[0013] The battery pack moves back and forth along the battery mounting slot. When it is connected to the power connection part, the locking block part enters the locking slot part, and the pin assembly extends into the slot hole part.

[0014] The present invention further includes at least one guide portion on each of the left and right side walls of the battery mounting slot, the guide portion having an inclined guide surface for guiding the battery pack into the battery mounting slot.

[0015] The present invention further includes, wherein the slot portion includes two protrusions disposed on the left and right sidewalls of the battery mounting slot, and the protrusions have rearward slots; the block portion includes two blocks disposed on the left and right sides of the battery pack.

[0016] The present invention further includes a pin assembly comprising a pin and a resilient reset member. The pin has a locking end with a limiting portion, and the resilient reset member allows the locking end to extend out of the battery pack and cooperate with the slot portion through the limiting portion. The pin also has a driving end extending out of the battery pack.

[0017] The present invention further includes a pin assembly located at the rear end of the battery pack, a driving member being provided at the driving end of the pin assembly, and a lifting strap being provided between the driving member and the front end of the battery pack.

[0018] The present invention further comprises that one end of the driving member is fixedly connected to the pin member by a fixing pin, and the other end of the driving member is provided with a belt hole for installing the lifting belt;

[0019] The front end of the battery pack is provided with a groove, and the front end of the lifting strap is fixed in the groove by a first fastener and a washer.

[0020] The present invention further includes a receiving groove at the rear end of the battery pack for accommodating the driving component, and a rotation limiting part is provided in the receiving groove to prevent the driving component from rotating.

[0021] The present invention further includes a flange extending outward from the ends of the left and right sidewalls of the battery mounting groove, forming a wiring mounting channel between the flange and the vehicle frame.

[0022] An electric scooter includes the aforementioned battery mounting mechanism.

[0023] The present invention further includes a frame comprising a frame body and a cover plate, the cover plate being rotatably mounted on the frame body, and a sealing strip being provided between the two.

[0024] A locking tongue is provided on the cover plate by a second fastener, and an electronic lock cylinder is provided in the vehicle frame body. The locking tongue is engaged with the lock hole of the electronic lock cylinder. When the electronic lock cylinder is de-energized, the cover plate can be opened by removing the second fastener.

[0025] The outstanding and beneficial technical effects of this invention compared to the prior art are:

[0026] 1. The battery pack of this invention is detachably mounted on the vehicle frame via a power mounting plate. The battery mounting slot on the power mounting plate restricts the lateral position of the battery pack; the slot on the power mounting plate and the locking block on the battery pack cooperate to restrict the vertical position of the battery pack; the slot on the power mounting plate and the pin assembly on the battery pack cooperate to restrict the front-rear position of the battery pack, thereby reliably fixing the battery pack position and avoiding poor contact of the battery pack power plug. During installation, the battery pack can be quickly assembled by simply sliding it forward within the battery mounting slot; during disassembly, it can be quickly removed by simply driving the pin assembly and simultaneously sliding the battery pack backward. This achieves both reliable installation and rapid disassembly of the battery pack, offering two benefits in one.

[0027] 2. The present invention provides at least one guide portion on each of the left and right side walls of the battery mounting slot, which forms an open structure with a larger upper end and a smaller lower end, for guiding the battery pack into the battery mounting slot and realizing automatic positioning of the left and right positions.

[0028] 3. This invention features a lifting strap on the battery pack. The lifting strap is connected to the pin assembly via a drive mechanism. Users can move the battery pack using the lifting strap, and can also raise and lower the pin assembly using the lifting strap. This allows users to easily assemble and disassemble the battery simply by operating the lifting strap, making it very convenient. Furthermore, the lifting strap is a strip-shaped structure, relatively small in size, and when not in use, it adheres to the surface of the battery pack, without occupying space in the battery installation compartment.

[0029] 4. The driving component of the present invention is located in the receiving groove at the rear end of the battery pack. A rotation limiting part is provided in the receiving groove to block the rotation of the driving component. The driving component is a thin sheet body, and one side of it abuts against the limiting convex surface, thereby limiting the rotation of the driving component and the pin component, making the operation of the lifting belt more comfortable and effortless.

[0030] 5. This invention includes an electronic lock. The lock tongue of the electronic lock is mounted on the cover plate via a second fastener. The rotating end of the second fastener is located on the outer side of the cover plate. When the electronic lock cylinder is powered off, the cover plate and the lock tongue can be separated by disassembling the second fastener, thereby opening the cover plate. This concealed unlocking method is not easily thought of by the average person. The structural design is simple and ingenious, ensuring unlocking even in a power-off state while also serving an anti-theft function.

[0031] 6. The left and right sidewalls of the battery mounting slot of the present invention extend outward with flanges, forming a wiring mounting channel with the vehicle frame. One side of the wiring mounting channel contains a brake cable for controlling the rear wheel speed, and the other side contains an electronic lock control cable for controlling the electronic lock. This makes the interior of the battery mounting compartment look more aesthetically pleasing and tidy, and facilitates the installation of the battery pack. Simultaneously, the power mounting plate protects the wiring within the wiring mounting channel from damage during battery pack installation and removal. Attached Figure Description

[0048] The present invention will be further described below with reference to specific embodiments:

[0049] like Figure 1-3 As shown, an electric scooter includes a frame 1, a battery pack 3, and a battery mounting mechanism.

[0050] The frame 1 includes a frame body 13 made of metal, a cover plate 14, a front frame mounting part 18, and a rear wheel mounting part 19. The frame body 13 is elongated and hollow inside to form a battery mounting compartment 11 for accommodating the battery pack 3. An elongated opening is provided on its upper surface, and the cover plate 14 is rotatably mounted on the front end of the opening via a hinge 16. The front frame mounting part 18, which connects to the front frame, is located at the front end of the frame body 13, and the rear wheel mounting part 19, which connects to the rear wheel, is located at its rear end.

[0051] like Figure 3 As shown, sealing steps are provided around the long opening, and sealing strips 15 are arranged on the sealing steps. The sealing strips 15 are preferably waterproof strips made of silicone. When the cover 14 is closed, the sealing strips 15 abut against the sealing steps, thereby improving the sealing performance of the long opening. In this embodiment, the frame body 13 is a closed frame. Sealing the long opening with the sealing strips 15 ensures the airtightness of the battery mounting compartment 11, preventing water from entering the battery mounting compartment 11. Simultaneously, the battery pack 3 in this embodiment also has a certain degree of waterproofness.

[0052] The vehicle frame 1 is provided with a power connection part, which includes a power socket 132 located at the front end of the battery mounting compartment 11 and / or a charging port 131 located on the side wall of the battery mounting compartment 11. The charging port 131 is provided with a charging end cover to facilitate users to directly charge the battery pack 3.

[0053] like Figure 4-5 As shown, the battery mounting mechanism includes a power mounting plate 2, upper and lower limit units 4, and front and rear limit units 5.

[0054] The power mounting plate 2 is preferably made of PC alloy, which has advantages such as high strength, high heat resistance, and high chemical corrosion resistance. The power mounting plate 2 has a bottom and sidewalls that extend integrally to the left and right sides of the bottom, thereby forming a battery mounting groove 21 in the middle of the power mounting plate 2. The bottom of the power mounting plate 2 has screw mounting holes and is fixed to the bottom of the battery mounting compartment 11 by screws.

[0055] The length of the battery mounting slot 21 is slightly greater than the length of the battery pack 3, allowing the battery pack 3 to slide along the length of the battery mounting slot 21, thereby enabling the power plug of the battery pack 3 to be plugged into the power socket 132. Simultaneously, the front end of the battery pack 3 abuts against the front end of the battery mounting compartment 11, achieving front-end positioning.

[0056] To facilitate the insertion of the battery pack 3 into the battery mounting slot 21, the width of the mounting slot 21 is greater than the width of the battery pack 3. At least one guide portion 22 is provided on the inner side of the sidewall. The upper end of the guide portion 22 forms an inclined guide surface 221, and its lower end forms a positioning surface 222 that adapts to the sidewall of the battery pack 3. This allows several guide portions 22 on both sides to form an open structure that is larger at the top and smaller at the bottom, guiding the battery pack 3 into the battery mounting slot 21. Simultaneously, since the distance between the positioning surfaces 222 on both sides precisely matches the outer contour width of the battery pack 3, after being guided by the guide surfaces 221, the battery pack 3 can automatically achieve left and right position calibration and limitation under its own gravity.

[0057] like Figure 6 As shown, the upper and lower limiting unit 4 includes a slot portion 41 disposed on the power mounting plate 2 and a block portion 42 disposed on the battery pack 3. Specifically, the slot portion 41 includes two protrusions disposed on the left and right side walls of the battery mounting groove 21, and the protrusions have slots with openings facing rearward; the block portion 42 includes two blocks disposed on the left and right sides of the rear end cover of the battery pack 3. When the blocks are inserted into the slots, the upper and lower limits of the battery pack 3 are achieved.

[0058] like Figure 7As shown, the front and rear limiting unit 5 includes a slot 51 provided on the power mounting plate 2 and a pin assembly provided on the rear end cover of the battery pack 3. The pin assembly includes a pin 52 and a resilient reset member 53. The rear end cover of the battery pack has a pin hole 35 for mounting the pin 52, and a limiting surface 351 for the resilient reset member 53 to abut against is provided in the pin hole 35. The pin 52 is cylindrical and has a driving end 523, a limiting part 521, and a snap-fit ​​end 522. The limiting part 521 is close to the snap-fit ​​end 522, and the driving end 523 extends out of the rear end cover after passing through the pin hole 35. The elastic reset member 53 is preferably a spring and is fitted onto the pin member 52. One end abuts against the limiting surface 351 in the pin hole 35, and the other end abuts against the limiting part 521, so that the snap-fit ​​end 522 extends out of the rear end cover of the battery pack 3 and cooperates with the slot part 51, thereby realizing the front and rear limiting of the battery pack 3.

[0059] like Figure 7 As shown, the left and right sidewalls of the battery mounting slot 21 extend outward with flanges 23, forming a wiring mounting channel 12 between them and the frame 1. In this embodiment, a brake cable 8 for controlling the rear wheel speed is provided in one side of the wiring mounting channel 12, and an electronic lock control cable 74 for controlling the electronic lock 7 is provided in the other side of the wiring mounting channel 12. Since the controller of the electric scooter is located on the frame 1 at the front of the battery mounting compartment 11, and the electronic lock 7 is located at the rear of the battery mounting compartment 11, arranging the electronic lock control cable 74, brake cable 8, and other cables in the wiring mounting channel 12 makes the interior of the battery mounting compartment 11 look more aesthetically pleasing and neat, and also facilitates the installation of the battery pack 3. At the same time, the power mounting plate 2 can protect the cables in the wiring mounting channel 12 from being bumped or knocked during the installation and removal of the battery pack 3.

[0060] like Figure 8 As shown, in order to facilitate the disengagement of the pin 52 from the slot 51, the driving end 523 of the pin 52 is provided with a driving member 54, and a lifting strap 31 is provided between the driving member 54 and the front end of the battery pack 3.

[0061] Specifically, the driving end 523 of the pin 52 has a mounting groove and a fixing hole. One end of the driving member 54 is inserted into the mounting groove and then fixedly connected to the pin 52 by a fixing pin 55. The other end of the driving member 54 is provided with a hole 541 for mounting the lifting strap 31, and the rear end of the lifting strap 31 is fixed in the hole 541. The front end of the battery pack 3 (i.e., the front end cover of the battery pack 3) is provided with a groove 32, and a threaded hole is provided in the groove 32. The front end of the lifting strap 31 is fixed in the threaded hole of the groove 32 by a first fastener and a washer 33. In addition, the washer 33 is provided with a fastening hole for the first fastener to pass through. At the same time, it is provided with several fixing spikes on the end face that fits the lifting strap 31. When the first fastener is tightened, the fixing spikes are inserted into the lifting strap 31, which can more effectively prevent the lifting strap 31 from sliding.

[0062] The size of the driving component 54 is larger than the diameter of the pin hole 35, which serves to limit the end of the pin 52, allowing the pin 52 to be movably disposed within the pin hole 35. Simultaneously, the driving component 54 also acts as a driving carrier to move the pin 52 away from the slot 51. Users can directly lift the pin 52 using the driving component 54 or by using the lifting strap 31 to lift the driving component 54.

[0063] When installing the battery pack 3, first place the battery pack 3 in a position slightly behind the battery mounting slot 21. Automatic left and right position calibration is achieved through the guide part 22. Then, drive the lifting strap 31 to move the battery pack 3 forward along the battery mounting slot 21. When it is connected to the power connection part, the locking block part 42 enters the locking slot part 41, and the pin assembly extends into the slot hole part 51 to achieve reliable fixation of the battery pack 3.

[0064] When it is necessary to disassemble or assemble the battery pack 3, the lifting strap 31 is applied diagonally backward. The lifting strap 31 drives the pin 52 to leave the slot 51 through the driving component 54. At the same time, the battery pack 3 is driven to move backward, so that the locking block 42 is disengaged from the locking slot 41, thereby realizing the quick disassembly of the battery pack 3, which is very convenient and fast.

[0065] To prevent the lifting strap 31 from rotating when the pin 52 is pulled, a receiving groove 34 for accommodating the drive member 54 is provided at the rear end of the battery pack 3. A rotation limiting part 341 is provided in the receiving groove 34 to block the rotation of the drive member 54. In this embodiment, the rotation limiting part 341 consists of two limiting convex surfaces. The drive member 54 is a thin sheet body, and one side of it abuts against the limiting convex surface, thereby limiting the rotation of the drive member 54 and the pin 52, making the operation of the lifting strap 31 more comfortable and effortless.

[0066] like Figure 4 As shown, an electronic lock 7 is provided between the cover plate 14 and the vehicle frame body 13. The electronic lock 7 includes a locking tongue 72 mounted on the cover plate 14 via a second fastener 71 and an electronic lock cylinder 73 fixed in the battery mounting compartment 11. In this embodiment, two second fasteners 71 are provided, preferably screws. The locking tongue 72 is L-shaped, with a second screw hole on one side that matches the second fastener 71, and a locking tongue opening on the other side that cooperates with the locking hole of the electronic lock cylinder 73 to achieve locking. The rotating end of the second fastener 71 is located on the outside of the cover plate 14. When the electronic lock cylinder 73 is de-energized, the cover plate 14 and the locking tongue 72 can be separated by disassembling the second fastener 71, thereby opening the cover plate 14.

[0067] Generally, electronic locks are equipped with two systems for opening and closing: one electronically controlled and the other mechanically controlled. Traditional mechanical control uses a key to open and close, and requires an additional mechanical transmission structure for unlocking, resulting in a complex and bulky electronic lock cylinder structure. In this embodiment, however, the cover plate 14 and the bolt 72 can be quickly separated using a hidden second fastener 71. This unlocking method is not easily thought of by the average person, ensuring unlocking even when power is off, while also providing anti-theft protection.

[0068] Preferably, the left and right side walls of the battery mounting compartment 11 are respectively provided with elastic pins 17 for abutting against the cover plate 14. When the electronic lock 7 is opened, the elastic pins 17 can directly push open the cover plate 14 and form an opening between the cover plate 14 and the frame body 13 that can accommodate a hand, making it convenient for the user to flip the cover plate 14.

[0069] Preferably, a foot pad groove is formed on the upper surface of the frame body 13, and a foot pad 6 is disposed in the foot pad groove. The foot pad 6 is provided with anti-slip texture to improve the user's driving experience. In this embodiment, the foot pad 6 is made of TPR material and is attached to the entire foot pad groove, while also covering the entire upper surface of the frame body 13 containing the cover plate 14. This is equivalent to adding another waterproof structure to the long opening, further reducing the risk of water entering the battery installation compartment 11.

[0070] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
