Technical Field

[0001] This utility model relates to the field of scooter technology, and specifically to a scooter with a removable battery. Background Technology

[0002] Electric scooters are based on traditional human-powered skateboards, powered by a built-in battery, primarily a lithium battery pack. Compared to traditional electric bicycles, electric scooters have advantages such as simple structure, small wheels, lightweight and convenient operation, and the ability to save significant social resources, making them popular among the general public.

[0003] Most scooters currently use fixed batteries, which are often non-removable and make charging inconvenient for users.

[0004] In addition, there are a few removable batteries on the market, but the removal process is extremely cumbersome, takes up a lot of space on the vehicle, the fixing method is not very reliable, and there are also great hidden dangers to riding safety.

[0005] The aforementioned problems have caused significant disruption to user experience and resulted in substantial financial waste for businesses. Therefore, a solution is needed for a scooter that features easily removable batteries, reliable mounting, an aesthetically pleasing design, and a simplified structure. Summary of the Invention

[0006] In view of the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a scooter with a detachable battery.

[0007] The technical solution adopted by this utility model to solve its technical problem is: A scooter with a detachable battery includes a frame tube, a battery, a front mounting bracket, a battery lock, a rear mounting bracket, and terminal blocks. The frame tube is hollow and has a strip-shaped notch on its top surface to form a cover tube. The battery is detachably inserted into the cover tube, with its top surface flush with the top surface of the cover tube, and no frame tube cover is provided. The left and right sides of the battery are restricted by the frame tube body. A front mounting bracket is fixedly installed inside the front end of the frame tube for engaging with the front end of the battery. A battery lock is installed on the front mounting bracket, with the keyhole of the battery lock located on the side of the frame tube. The locking pin of the battery lock is inserted into the front hole of the battery to restrict the vertical movement of the battery. A rear mounting bracket is fixedly installed inside the rear end of the frame tube for engaging with the rear end of the battery. A terminal block is provided on the rear mounting bracket, and the rear end of the battery is connected to the terminal block for power supply.

[0008] Furthermore, the frame tube is designed as a single piece with a bent configuration, including an interconnected vertical section and a horizontal section; the horizontal section has a strip-shaped notch to form a horizontal notch tube.

[0009] Furthermore, the width of the horizontal notch tube is 60-80mm and the height is 80-100mm; the cross-section of the strip notch is set as U-shaped.

[0010] Furthermore, the front mounting bracket is connected to the front end of the frame tube by screws. Even further, a front mounting bracket locking plate is welded to the upper part of the front end of the frame tube. The front mounting bracket locking plate includes a central positioning hole and two side fixing holes. Screws are inserted into the fixing holes on both sides of the front end of the front mounting bracket. A guide boss is provided in the center of the front end of the front mounting bracket, and the guide boss matches the positioning hole.

[0011] Furthermore, the battery lock and the front fixing seat are connected by screws, and the lock tongue of the battery lock can movably protrude from the front fixing seat; the front fixing seat is also provided with a spring pin, and the spring pin and the front fixing seat are fixed by applying force to press them together.

[0012] Furthermore, the rear end of the frame tube and the rear mounting bracket are connected by screws; the rear mounting bracket and the connector terminal are connected by screws.

[0013] Furthermore, the front and rear fixing seats are made of plastic and manufactured using injection molding.

[0014] Furthermore, the frame tube is made of aluminum; the frame tube is manufactured using a water-expanding process.

[0015] Furthermore, a rear fork is welded to the rear end of the frame tube; a mudguard is fixed to the rear end of the frame tube by bolts.

[0016] The advantages of this utility model are as follows: (1) Compared with the removable batteries on the market (which require a top cover on the frame to be removed before the battery can be removed), the scooter with the removable battery of this utility model can be removed simply by unscrewing the battery lock. The operation of removing the battery is very simple and convenient for the user, and it is convenient for the user to charge the battery.

[0017] (2) Compared to the detachable batteries on the market (the battery fixing structure is generally limited on all four sides, with a large amount of play in the front, back, left, right, up and down, which poses a great safety risk in harsh riding environments), the scooter using the detachable battery of this utility model has a very reliable battery fixing method: First, both the front and rear mounting brackets are fixed with screws, ensuring a secure assembly and guaranteeing safety. Secondly, the battery's front-to-back direction is restricted by the front and rear mounting brackets, its left-to-right direction is restricted by the frame tubes, and its up-to-down direction is restricted by the battery lock, thus securing the battery in all directions and ensuring riding safety.

[0018] (3) The scooter with detachable battery of this utility model has a simpler structural design. The battery is directly placed in the frame tube, and the top plate of the battery is flush with the top of the frame tube. The frame cover plate is no longer set on the top of the battery, and the overall shape of the vehicle is more harmonious and beautiful.

[0019] (4) The frame tube of the scooter with detachable battery of this utility model is made of aluminum material, which achieves the goal of lightweighting compared with the iron frame tubes on the market. The frame tube adopts an integrated design, avoiding the welding and assembly of the slant tubes and bottom frame in the existing market, simplifying the process. The frame tube adopts a strip tube design and the frame tube width is relatively narrow. In addition, the pedals on both sides of the frame tube can be folded upward, so the final product width is relatively narrow, thus greatly increasing the packing capacity.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1 to 11 As shown, the scooter with a detachable battery in this embodiment includes a frame tube 1, a battery 2, a front fixing seat 4, a battery lock 5, a spring pin 6, a rear fixing seat 7, a wiring terminal 8, and a front fixing seat locking plate 10.

[0023] In this embodiment, the frame tube 1 is made of aluminum, which achieves the goal of lightweighting compared to the iron frames on the market.

[0024] The frame tube 1 is manufactured using a water-expanding process, resulting in a more aesthetically pleasing appearance compared to frames on the market.

[0025] The frame tube 1 is a one-piece design at the front and rear, eliminating the need for welding and assembly of the slanted tubes and bottom frame found in existing models, thus simplifying the manufacturing process.

[0026] The frame tube 1 is bent and includes an interconnected vertical section and a horizontal section. The upper end of the vertical section is welded to the head tube, and the tail end of the horizontal section is welded to the rear fork 9.

[0027] The horizontal section of the frame tube 1 is hollow, forming a storage cavity for the battery 2, enabling the battery 2 to be removable for easy charging. Specifically, a section is missing from the top of the horizontal section, forming a strip-shaped notch; thus, the horizontal section becomes a horizontal notched tube. Figure 1 and Figure 3 As shown, the battery 2 can be detachably placed into the horizontal notch tube through the strip-shaped notch.

[0028] Furthermore, the top surface of battery 2 is flush with the top surface of the horizontally notched tube, such as Figure 1 As shown, the conventional frame tube cover plate is omitted, resulting in a simpler structure.

[0029] Moreover, the size of battery 2 matches the size of the strip notch. When battery 2 is placed inside the strip notch, both the left and right sides of battery 2 are restricted by the inside of the frame tube 1.

[0030] In this embodiment, the width of the horizontal notch tube is 60-80mm, and the height is 80-100mm. The cross-section of the strip notch is set as U-shaped.

[0031] In addition, the battery 2 in this embodiment also incorporates the following measures to prevent rainwater damage, thus achieving a rainproof effect: (1) A drainage hole is opened at the bottom of the frame tube 1 so that rainwater can flow out quickly once it rains; (2) For example Figure 3 , Figure 10 and Figure 11 As shown, the top four edges of battery 2 extend outwards, and the widened treatment forms a brim similar to a hat, which helps to prevent rainwater from entering the interior of battery 2. (3) In addition, the electrical performance is not affected by water contact with the wiring terminal 8 on the rear mounting base 7.

[0032] Among them, such as Figure 7 As shown, a front fixing seat locking piece 10 is provided at the front end of the horizontal cap tube. The front fixing seat locking piece 10 is welded to the upper front end of the horizontal cap tube. Preferably, the front fixing seat locking piece 10 is made of aluminum sheet metal.

Specifically, screws are inserted into the mounting holes on both sides of the front end of the front mounting bracket 4, and a guide boss is provided in the middle of the front end of the front mounting bracket 4, which matches the positioning hole. The front mounting bracket 4 is a plastic part, manufactured by injection molding.

[0034] The front mounting bracket 4 is used for snap-fit ​​connection with the front end of battery 2. For example... Figure 4 and Figure 11 As shown, the front mounting bracket 4 is equipped with a battery lock 5 and a spring pin 6. The battery lock 5 and the front mounting bracket 4 are connected by screws. The locking tongue of the battery lock 5 protrudes from the front mounting bracket 4 and engages with the front end of the battery 2, thereby restricting the vertical movement of the battery 2. The keyhole of the battery lock 5 is located on the side of the frame tube 1. When the key is inserted and turned, the locking tongue of the battery lock 5 retracts into the front mounting bracket 4, releasing the restriction on the front end of the battery 2. The spring pin 6 and the front mounting bracket 4 are fixed by applying force. The spring pin 6 is pressed down by the weight of the battery 2 itself. When the battery 2 is removed, the spring pin 6 automatically pops out.

[0035] Among them, such as Figure 5 As shown, the rear end of the frame tube 1 and the rear mounting bracket 7 are connected by screws. The rear mounting bracket 7 is a plastic part manufactured using injection molding. The rear mounting bracket 7 snaps into the rear end of the battery 2. A connector terminal 8 is provided on the rear mounting bracket 7. The rear mounting bracket 7 and the connector terminal 8 are connected by screws. The rear end of the battery 2 is connected to the connector terminal 8 for power supply. Figure 9 As shown, a guide boss is provided in the middle of the upper end of the rear fixing seat 7 to facilitate the rear end of the battery 2 to be snapped into the rear fixing seat 7.

[0036] The rear fork 4 is connected to the end of the frame tube 1, and the rear fork 4 is fixed to the end of the frame tube 1 by welding.

[0037] The rear end of the frame tube 1 is also connected to a mudguard 3, such as... Figure 2 As shown, the bottom of the mudguard 3 is provided with screw holes 11, which are connected to the frame tube 1 by screws.

[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute a limitation on the scope of protection of the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the scope of protection of the claims of the present utility model.
