Description

Technical Field

[0001] This invention relates to the field of electric bicycle technology, and more particularly to an electric bicycle with an easily removable battery. Background Technology

[0002] Electric bicycles are vehicles that use batteries as auxiliary power and, based on ordinary bicycles, are equipped with motors, controllers, batteries, throttles, brake levers, and display systems. With increasing environmental awareness and the growing severity of urban traffic congestion, electric bicycles have become widely popular as a green and convenient mode of transportation.

[0003] Currently, various types of electric bicycles are available on the market, some of which feature removable batteries to extend range and facilitate charging. However, these electric bicycles still have significant drawbacks in terms of battery replacement: most removable batteries are installed below the seat frame and are removed and installed via a latch or pull-out mechanism. However, when replacing the battery, the seat must be adjusted to pull it out, making disassembly and assembly inconvenient. Furthermore, the plug of these removable batteries is often external to the vehicle body, making it susceptible to water damage in rainy weather, which could lead to short circuits when connected, posing a safety hazard.

[0004] To address the aforementioned issues, we propose an electric bicycle with an easily removable battery. By modifying the structure of the battery compartment, we achieve convenient battery replacement while simultaneously enclosing the electrical operating components to prevent them from being affected by weather and potential damage. Summary of the Invention

[0005] To overcome the shortcomings of existing electric bicycles, such as inconvenient battery removal and exposed plugs that are easily affected by external factors and pose safety hazards, the technical problem to be solved is to provide an electric bicycle with an easily removable battery. This is achieved by changing the structure of the battery compartment to facilitate battery replacement, while simultaneously enclosing the electrical operating components to avoid the impact of weather and potential damage.

[0006] This invention is implemented through the following technical means: an electric bicycle with an easily detachable battery, comprising an electric bicycle, a fixed frame fixedly connected to the frame of the electric bicycle, a connecting frame rotatably connected to the bottom end of the fixed frame, a battery compartment fixedly connected to the top end of the connecting frame, a power input terminal fixedly connected inside the battery compartment, a longitudinally symmetrical torsion spring connected between the connecting frame and the fixed frame, a key lock fixedly connected to the top end of the fixed frame, the key lock locking the battery compartment, an opening mechanism for pushing the battery upward for easy removal on the fixed frame and the battery compartment, and a guide mechanism for limiting the position of the battery inside the battery compartment.

[0007] In one embodiment, the opening mechanism includes a limiting frame, which is fixedly connected to the bottom of a fixed frame. A mounting plate is fixedly connected to the bottom of the battery compartment. A longitudinally symmetrical contact rod is fixedly connected to the limiting frame. A fixed plate is fixedly connected inside the mounting plate. The contact rod extends through the connecting frame into the mounting plate and the fixed plate. A top plate is slidably connected inside the fixed plate. The top plate and the contact rod are pressed together. A transversely symmetrical first spring is connected between the top plate and the fixed plate.

[0008] In one embodiment, the fixing plate has a laterally symmetrical protrusion, and the top plate has a laterally symmetrical recess that matches the protrusion of the fixing plate.

[0009] In one embodiment, the guiding mechanism includes longitudinally symmetrical slide rails, which are fixedly connected to the battery compartment. A connecting plate is slidably connected between the longitudinally symmetrical slide rails, and longitudinally symmetrical rubber strips are fixedly connected to the connecting plate. A clamping plate is fixedly connected to the rubber strip.

[0010] In one embodiment, the top of the clamp is an outwardly bent inclined structure.

[0011] In one embodiment, a locking mechanism for limiting the upper side of the battery is also included. The locking mechanism is disposed in the battery compartment and includes longitudinally symmetrical fixing blocks. The longitudinally symmetrical fixing blocks are fixedly connected to the battery compartment. A sliding block is slidably connected inside the fixing blocks. A second spring is connected between the sliding block and the adjacent fixing block. An elastic rope is fixedly connected to the side of the sliding block that is far away from each other. A longitudinally symmetrical guide wheel is rotatably connected to the battery compartment. The tail end of the elastic rope passes around the adjacent guide wheel and is connected to the fixing frame.

[0012] In one embodiment, the inner end of the sliding block is wedge-shaped.

[0013] In one embodiment, a pushing mechanism is further included for controlling the stable docking of the power output terminal and the power input terminal of the battery. The pushing mechanism is disposed in the battery compartment and includes longitudinally symmetrical rubber blocks. The longitudinally symmetrical rubber blocks are fixedly connected to the side of the battery compartment near the power input terminal. A first airbag is fixedly connected inside the fixed plate. A lower pressure plate is connected to the top of the first airbag. The lower pressure plate is fixedly connected to the top plate. A connecting tube is connected to the first airbag. A second airbag is fixedly connected inside the battery compartment. The second airbag is connected to the tail end of the connecting tube.

[0014] In one embodiment, an auxiliary mechanism for dissipating heat inside the battery compartment when the weather is good is also included. The auxiliary mechanism is disposed in the battery compartment and includes a guide block, which is fixedly connected to the battery compartment. A baffle is slidably connected to the guide block, and an electric push rod is fixedly connected to the guide block. The telescopic end of the electric push rod is fixedly connected to the baffle. A sensing plate is fixedly connected to the guide block and is electrically connected to the electric push rod.

[0015] In one embodiment, the battery compartment has longitudinally symmetrical heat dissipation holes.

[0016] The present invention has the following advantages: 1. When the key lock is opened, the battery compartment rotates to the right and is misaligned with the seat of the electric bicycle. At this time, the battery can be directly pulled out without adjusting the seat position, making battery installation and removal more convenient. After the battery is inserted into the battery compartment, the power output terminal on the battery is connected to the power input terminal for power supply. By enclosing the electrical operating components in the battery compartment, the effects of weather and potential damage can be avoided.

[0017] 2. When the battery is inserted into the battery compartment, the top plate will be pressed down and slide down. It will be locked in place by the cooperation of the recessed part and the protruding part of the fixing plate. When the battery compartment is turned to the right to open, the top plate will be pressed upward by the contact rod after turning to the right. The upward movement of the top plate will push the battery upward so that the staff can take the battery out of the battery compartment.

[0018] 3. When the battery is inserted into the battery compartment, the front and rear clamps will contact the front and rear sides of the battery, and the bottom of the battery will contact the connecting plate. After the battery is inserted into the battery compartment, the clamps can restrict the position of the battery and prevent the battery from shaking inside the battery compartment.

[0019] 4. After the battery is inserted into the battery compartment, the sliding blocks slide in opposite directions and lock onto the upper side of the battery, further restricting the position of the battery and preventing it from shifting.

[0020] 5. After the battery is inserted into the battery compartment, the second airbag expands and fills the gap on the right side of the battery, causing the battery to fit snugly to the left. The rubber clip will then lock into the groove on the left side of the battery, further positioning the battery and ensuring a stable connection between the power output end and the power input end on the left side of the battery.

[0021] 6. When the weather is good, the heat dissipation holes cool the batteries inside the battery compartment. When the sensor plate detects rain, the baffle slides down and blocks the heat dissipation holes on the battery compartment to prevent water from entering the battery compartment.

Detailed Implementation

[0037] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0038] Example 1: An electric bicycle with an easily removable battery, such as Figures 1-6As shown, the device includes an electric bicycle 1, a battery compartment 2, a power input terminal 21, a connecting frame 22, a torsion spring 23, a fixing frame 3, a key lock 4, an opening mechanism 5, and a guide mechanism 6. The fixing frame 3 is fixedly connected to the frame of the electric bicycle 1. The connecting frame 22 is rotatably connected to the lower part of the fixing frame 3. The battery compartment 2 is fixedly connected to the upper side of the connecting frame 22. The power input terminal 21 is fixedly connected to the lower left side of the battery compartment 2. A torsion spring 23 is symmetrically connected between the connecting frame 22 and the fixing frame 3. The key lock 4 is fixedly connected to the upper part of the fixing frame 3 and locks the battery compartment 2. The fixing frame 3 and the battery compartment 2 are provided with an opening mechanism 5 for pushing the battery upward for easy access. The battery compartment 2 is provided with a guide mechanism 6 for limiting the position of the battery.

[0039] In the initial state, the key lock 4 locks the battery compartment 2, and the torsion spring 23 is in a deformed state. Then, the operator opens the key lock 4. Under the action of the torsion spring 23 returning to its original position, the connecting bracket 22 drives the battery compartment 2 to rotate to the right and open. After the battery compartment 2 rotates to the right, it is misaligned with the seat of the electric bicycle 1. At this time, the battery can be directly pulled out without adjusting the seat position, making battery removal and installation more convenient. When the battery is inserted into the battery compartment 2, the power output terminal on the battery connects with the power input terminal 21 to supply power. Then, the operator controls the battery compartment 2 to rotate to the left to close it, and then controls the key lock 4 to lock the position of the battery compartment 2. By enclosing the electrical operating components inside the battery compartment 2, the effects of weather and potential damage can be avoided.

[0040] like Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the opening mechanism 5 includes a limit frame 51, a mounting plate 52, a contact rod 53, a fixing plate 54, a top plate 55, and a first spring 56. The lower part of the fixing frame 3 is fixedly connected to the limit frame 51. The bottom of the battery compartment 2 is fixedly connected to the mounting plate 52. The limit frame 51 is fixedly connected to the front and rear symmetrical contact rods 53. The mounting plate 52 is fixedly connected to the fixing plate 54. The contact rods 53 extend through the connecting frame 22 and into the mounting plate 52 and the fixing plate 54. The top plate 55 is slidably connected to the fixing plate 54. The top plate 55 and the contact rods 53 are pressed together. The lower part of the fixing plate 54 is provided with symmetrical protrusions. The lower part of the top plate 55 is provided with symmetrical recesses that match the protrusions of the fixing plate 54. The top plate 55 and the fixing plate 54 are connected by symmetrical first springs 56.

[0041] When the battery is inserted into the battery compartment 2, the top plate 55 is pressed down and slides, the first spring 56 deforms, and after the top plate 55 slides down, it is locked in place by the recessed part and the protruding part of the fixing plate 54, so that the top plate 55 is in the lowered state. When the battery compartment 2 is rotated to the right to open, the limiting frame 51 and the contact rod 53 are connected to the fixing frame 3 and remain stationary, while the mounting plate 52, the fixing plate 54 and the top plate 55 follow the battery compartment 2 to rotate to the right. After the top plate 55 rotates to the right, it is pressed upward by the contact rod 53, which causes the recessed part to separate from the protruding part of the fixing plate 54. At this time, under the action of the first spring 56 resetting, the top plate 55 slides upward and pushes the battery upward so that the staff can take the battery out of the battery compartment 2.

[0042] like Figure 3 , Figure 9 and Figure 10 As shown, the guide mechanism 6 includes a slide rail 61, a connecting plate 62, a rubber strip 63, and a clamping plate 64. The front and rear sides of the battery compartment 2 are fixedly connected to the slide rail 61. The connecting plate 62 is slidably connected between the front and rear slide rails 61. The front and rear parts of the connecting plate 62 are fixedly connected to the rubber strip 63. The clamping plate 64 is fixedly connected to the rubber strip 63. The upper part of the clamping plate 64 is an outwardly bent inclined structure.

[0043] When the battery is inserted into the battery compartment 2, it will contact the front and rear clamps 64 and then enter between the front and rear clamps 64. Under the action of the rubber strip 63, the front and rear clamps 64 will contact the front and rear sides of the battery. When the battery is inserted downward into the battery compartment 2, the lower side of the battery will contact the connecting plate 62. The connecting plate 62 is guided by the slide rail 61, and the battery will push the connecting plate 62 to slide downward together. After the battery is inserted into the battery compartment 2, the clamps 64 can restrict the position of the battery and prevent the battery from shaking in the battery compartment 2.

[0044] Example 2: Based on Example 1, such as Figure 2 , Figure 3 , Figure 9 and Figure 10 As shown, it also includes a locking mechanism 7 for limiting the upper side of the battery. The locking mechanism 7 includes a fixed block 71, a sliding block 72, a second spring 73, an elastic rope 74, and a guide wheel 75. Fixed blocks 71 are fixedly connected to the front and rear sides of the upper part of the battery compartment 2. The sliding block 72 is slidably connected inside the fixed block 71. The upper side of the inner end of the sliding block 72 is an inclined surface. The second spring 73 is connected between the sliding block 72 and the adjacent fixed block 71. The elastic rope 74 is fixedly connected to the outer side of the sliding block 72. The guide wheel 75 is rotatably connected to the front and rear sides of the upper part of the battery compartment 2. The tail end of the elastic rope 74 passes around the adjacent guide wheel 75 and is connected to the fixing frame 3.

[0045] When the battery compartment 2 is rotated to the right to open, the fixed block 71 will also drive the sliding block 72 to rotate to the right. At this time, under the action of the elastic rope 74, the sliding block 72 will be pulled to slide in the opposite direction, and the second spring 73 will deform. Then, the operator inserts the battery into the battery compartment 2. Since the upper side of the inner end of the sliding block 72 is inclined, the battery can also directly squeeze the two sliding blocks 72 in the front and back to slide in the opposite direction when it is inserted into the battery compartment 2. After the battery is placed, the battery compartment 2 is rotated to the left to close, which makes the elastic rope 74 relax. Under the action of the second spring 73 to reset, the two sliding blocks 72 in the front and back slide to reset and lock on the upper side of the battery, further restricting the position of the battery and preventing the battery from being displaced.

[0046] like Figure 3 , Figure 11 and Figure 12 As shown, it also includes a pushing mechanism 8 for controlling the stable docking of the power output terminal and the power input terminal 21 of the battery. The pushing mechanism 8 includes a rubber block 81, a first airbag 82, a lower pressure plate 83, a connecting pipe 84, and a second airbag 85. The lower part of the battery compartment 2 is fixedly connected with symmetrical rubber blocks 81. The first airbag 82 is fixedly connected to the fixed plate 54. The lower pressure plate 83 is connected to the upper side of the first airbag 82. The lower pressure plate 83 is fixedly connected to the top plate 55. The connecting pipe 84 is connected to the upper part of the first airbag 82. The lower right part of the battery compartment 2 is fixedly connected with the second airbag 85. The second airbag 85 is connected to the tail end of the connecting pipe 84.

[0047] After the battery is inserted into the battery compartment 2, the second airbag 85 is located on the right side of the battery. The top plate 55 is squeezed and slides downward, which also causes the lower pressure plate 83 to move downward. The lower pressure plate 83 moves downward and compresses the first airbag 82. The air in the first airbag 82 enters the second airbag 85 through the connecting pipe 84, which causes the second airbag 85 to expand. The expansion of the second airbag 85 fills the gap on the right side of the battery, making the battery fit tightly to the left. The rubber clip 81 on the lower left side of the battery compartment 2 will then be inserted into the groove on the left side of the battery to further position the battery, so that the power output end on the left side of the battery is stably connected to the power input end 21. When the top plate 55 slides upward, it also causes the lower pressure plate 83 to move upward. Under the upward pulling of the lower pressure plate 83 and the rebound of the first airbag 82 itself, the first airbag 82 expands and sucks out the air in the second airbag 85 through the connecting pipe 84, and the second airbag 85 then contracts.

[0048] like Figure 2 , Figure 3 , Figure 13 and Figure 14As shown, it also includes an auxiliary mechanism 9 for dissipating heat inside the battery compartment 2 when the weather is good. The auxiliary mechanism 9 includes a guide block 91, a baffle 92, an electric push rod 93, and a sensor plate 94. The guide block 91 is fixedly connected to the upper right side of the battery compartment 2, and the baffle 92 is slidably connected to the guide block 91. There are two heat dissipation holes on both the front and rear sides of the battery compartment 2. The electric push rod 93 is fixedly connected to the guide block 91. The telescopic end of the electric push rod 93 is fixedly connected to the upper part of the baffle 92. The sensor plate 94 is fixedly connected to the guide block 91, and the sensor plate 94 is electrically connected to the electric push rod 93.

[0049] In the initial state, the baffle 92 is misaligned with the heat dissipation holes on the battery compartment 2, and the heat dissipation holes dissipate heat from the battery inside the battery compartment 2. When the sensor plate 94 senses rain, the sensor plate 94 controls the electric push rod 93 to shorten through the controller. The shortening of the electric push rod 93 causes the baffle 92 to slide downward. After the baffle 92 slides downward, it blocks the heat dissipation holes on the battery compartment 2, preventing water from entering the battery compartment 2.

[0050] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. All equivalent substitutions made within the principles of the present invention should be included within the scope of protection of the present invention. Contents not described in detail in this invention are existing technologies known to those skilled in the art.
