Description

Technical Field

[0001] This invention relates to the field of electric bicycle instrument technology, specifically to an anti-reflective electric bicycle instrument. Background Technology

[0002] An electric bicycle is a mechatronic personal transportation vehicle that uses a battery as an auxiliary power source and is based on a regular bicycle. It is equipped with a motor, controller, battery, throttle, and other control components and a display instrument system. Generally, the instrument of an electric bicycle is relatively simple, only needing to display information such as speed and battery level.

[0003] Existing electric bicycle gauges are generally assembled from two housings. During assembly, to improve sealing and waterproofing, rainwater is prevented from entering the gauge through the gap between the two housings. However, after the two housings are assembled and sealed with a sealing ring, the heat generated by the internal components cannot dissipate, accelerating the aging of the equipment. Without a sealing ring, the waterproofing effect is easily reduced. To address these issues, we propose an anti-reflective electric bicycle gauge that allows for good ventilation in sunny weather and proper sealing in rainy weather. Furthermore, because the gauge lacks protective features, strong sunlight can cause glare when the gauge is illuminated from the side, affecting visibility. Summary of the Invention

[0004] This invention proposes an anti-reflective electric bicycle instrument panel, which solves the problems in related technologies where electric bicycle instruments can not be well ventilated in sunny weather, cannot be well sealed in rainy weather, and can be reflected by sunlight shining from the side when the sunlight is strong.

[0005] The technical solution of the present invention is as follows: An anti-reflective electric bicycle instrument includes: a lower shell and an upper shell; a ventilation mechanism located in the inner cavity of the lower shell for ventilating the interior of the lower shell; an arc-shaped cover fixedly connected to the top of the upper shell, and the arc-shaped cover is inclined towards the upper shell in an inward V-shape; and a sealing connector located between the lower shell and the upper shell for sealing the space between the lower shell and the upper shell and for sealing the ventilation mechanism. The sealing connector includes an annular auxiliary block fixedly connected to the inner side of the lower shell, an annular mating block fixedly connected to the inner side of the upper shell, a sealing airbag installed on the outer wall of the annular auxiliary block, and a return component for assisting the sealing airbag to reset at the bottom of the sealing airbag.

[0006] As a further embodiment of the present invention: the ventilation mechanism includes a ventilation groove formed on the outer wall of the lower shell and passing through the annular auxiliary block and communicating with the interior of the lower shell, wherein a first filter screen and two second filter screens are fixedly connected to the inner side of the ventilation groove.

[0007] As a further embodiment of the present invention: the sealing connector further includes a retention groove and a sealing chamber formed inside the annular auxiliary block. An annular piston block is provided between the retention groove and the sealing chamber, separating the retention groove and the sealing chamber by the annular piston block. An air guide pipe is fixedly connected to the air inlet of the sealing airbag, and the air guide pipe communicates with the sealing chamber. A first placement groove is formed inside the annular auxiliary block. A miniature electric push rod is installed inside the first placement groove. A connecting plate is connected to the output end of the miniature electric push rod. A connecting column is fixedly connected to the top of the connecting plate. A circular piston block is fixedly connected to the top of the connecting column. A groove is provided, and a sleeve is provided inside the groove. A sliding rod is slidably connected to the inner side of the sleeve. A second connecting spring is fixedly connected to the bottom of the sliding rod. One end of the second connecting spring is fixedly connected to the circular piston block. A fixing block is fixedly connected to the top of the sliding rod. The fixing block is fixedly connected to the inner side of the annular piston block. A corrugated hose is fixedly connected to the bottom of the annular piston block, and one end of the corrugated hose is fixedly connected to the inner side of the annular auxiliary block. A drainage aid is provided on the inner side of the annular auxiliary block and the outer wall of the sliding rod. A humidity sensor is installed on the inner side of the ventilation slot, and the humidity sensor is located between the two first filters.

[0008] As a further embodiment of the present invention: a second blocking block is fixedly connected to the inner side of the annular auxiliary block at the top of the annular piston block, and a first blocking block is installed on the inner side of the sealing chamber below the annular piston block.

[0009] As a further embodiment of the present invention: the drainage aid includes absorbent cotton placed inside the retention groove, and the bottom of the absorbent cotton is glued to the top of the annular piston block. A flow pipe is fixedly connected to the inner side of the annular auxiliary block, and the circular piston block is slidably connected inside the flow pipe. A drain pipe is fixedly connected to the drain outlet of the flow pipe, and a water level sensor is installed on the outside of the sliding rod.

[0010] As a further embodiment of the present invention: the top of the annular piston block is provided with a through hole communicating with the corrugated hose, and the fixing block is installed inside the through hole.

[0011] As a further embodiment of the present invention: the top of the annular auxiliary block is provided with an inclined surface at the edge of the retention groove, and the inner side of the absorbent cotton is attached to the retention groove.

[0012] As a further embodiment of the present invention: the return assembly includes a second placement groove formed inside the annular auxiliary block, a loop-shaped frame slidably connected inside the second placement groove, a first connecting spring fixedly connected to the bottom of the loop-shaped frame, one end of the first connecting spring being fixedly connected to the annular auxiliary block, the top of the loop-shaped frame fitting against the bottom of the sealing airbag, an installation groove matching the sealing airbag being provided inside the annular auxiliary block, the sealing airbag being installed inside the installation groove, and a notch communicating with the ventilation groove being provided inside the annular auxiliary block, the size of the notch matching the loop-shaped frame.

[0013] The working principle and beneficial effects of this invention are as follows:

[0014] 1. By setting up a ventilation mechanism and a sealing connector, the air flowing outside can pass through the first and second filters and enter the lower and upper shells when the user is riding on a sunny day. This allows the heat generated by the operation of the equipment inside the lower and upper shells to be exchanged with the outside air, thus dissipating heat. When the user is riding on a rainy day, the sealing airbag expands to seal the gap between the lower and upper shells. At the same time, the expansion of the sealing airbag can fill the space between the first and second filters, thereby improving the sealing effect between the lower and upper shells and thus improving the overall practicality and service life of the device.

[0015] 2. By setting up the cooperation of components such as the U-shaped frame, when the sealing airbag expands, it will push the U-shaped frame to squeeze the first connecting spring downward. When the U-shaped frame retracts into the second placement groove, the sealing airbag can seal the gap between the first filter screen and the second filter screen. When the annular piston block resets and draws the air inside the sealing airbag into the sealing chamber, the squeezing force of the sealing airbag on the U-shaped frame will gradually decrease, so that the first connecting spring will push the U-shaped frame to reset. The U-shaped frame can push away the sealing airbag stuck between the first filter screen and the second filter screen, avoiding the sealing airbag blocking the airflow between the first filter screen and the second filter screen.

[0016] 3. By coordinating components such as absorbent cotton, when the electric bicycle is placed outdoors and not started, rainwater flows into the gap between the lower and upper shells and wets the absorbent cotton. The absorbent cotton will absorb the water, and the inclined surface can guide the excess water into the retention groove. Since the absorbent cotton becomes heavier after absorbing water, when the weight of the absorbent cotton reaches a certain threshold, it will push the annular piston block to move downwards, allowing the gas inside the sealing chamber to enter the sealing airbag. This allows the sealing airbag to expand automatically, thereby sealing the gap between the lower and upper shells, thus improving the overall sealing performance of the device and its overall practicality.

[0017] 4. By setting up a drainage auxiliary device, when the electric bicycle is placed outdoors and not started, and the absorbent cotton absorbs too much water and accumulates above the circular piston block, when the electric bicycle is started, the water level sensor will detect that there is too much water inside the corrugated hose and generate a signal to the controller. The controller will then control the micro electric push rod to start, so that the output end of the micro electric push rod drives the connecting plate to move the circular piston block downward through the connecting column. When the circular piston block is in contact with the top of the first blocking block, the circular piston block continues to move downward and pulls one end of the second connecting spring to continue moving until the circular piston block moves below the drain outlet of the flow pipe, so that the excess water on the top of the circular piston block can be discharged to the outside through the drain pipe, thereby improving the drainage effect of the device.

[0018] 5. By setting up an arc-shaped cover 35, a black film can be attached to the surface of the arc-shaped cover 35. Since the arc-shaped cover 35 is tilted upwards in an inward V-shape towards the upper shell 2, the tilted arc-shaped cover 35 can shield the instruments inside the assembled lower shell 1 and upper shell 2 from light, thereby reducing the reflection of sunlight shining from the side onto the upper shell 2, so that the user can observe during riding.

[0034] Example 1:

[0035] Please see Figures 1-10In this embodiment of the invention, an anti-reflective electric bicycle instrument includes: a lower shell 1 and an upper shell 2; a ventilation mechanism located in the inner cavity of the lower shell 1 for ventilating the interior of the lower shell 1; an arc-shaped cover 35 fixedly connected to the top of the upper shell 2, and the arc-shaped cover 35 is inclined upwards towards the upper shell 2 in an inward V-shape; and a sealing connector located between the lower shell 1 and the upper shell 2 for sealing the space between the lower shell 1 and the upper shell 2 and for sealing the ventilation mechanism. The sealing connector includes an annular auxiliary block 3 fixedly connected to the inner side of the lower shell 1, and an annular mating block 6 fixedly connected to the inner side of the upper shell 2. The outer wall of the annular auxiliary block 3 is fitted with... The airbag 4 has a ventilation mechanism including a ventilation groove 10 formed on the outer wall of the lower shell 1 and passing through the annular auxiliary block 3 to communicate with the interior of the lower shell 1. A first filter screen 5 and two second filters screens 30 are fixedly connected to the inner side of the ventilation groove 10. The sealing connector also includes a retention groove 32 and a sealing chamber 20 formed on the inner side of the annular auxiliary block 3. An annular piston block 21 is provided between the retention groove 32 and the sealing chamber 20, separating the retention groove 32 and the sealing chamber 20. An air guide pipe 28 is fixedly connected to the air inlet of the airbag 4, and the air guide pipe 28 communicates with the sealing chamber 20. The inner side of the annular auxiliary block 3... A first placement slot 12 is provided, and a miniature electric push rod 7 is installed inside the first placement slot 12. The output end of the miniature electric push rod 7 is connected to a connecting plate 8. A connecting post 13 is fixedly connected to the top of the connecting plate 8. A circular piston block 27 is fixedly connected to the top of the connecting post 13. A groove 34 is provided on the top of the circular piston block 27. A sleeve 25 is provided inside the groove 34. A sliding rod 24 is slidably connected to the inner side of the sleeve 25. A second connecting spring 26 is fixedly connected to the bottom of the sliding rod 24. One end of the second connecting spring 26 is fixedly connected to the circular piston block 27. A fixing block is fixedly connected to the top of the sliding rod 24. 22. The fixing block 22 is fixedly connected to the inner side of the annular piston block 21. The bottom of the annular piston block 21 is fixedly connected to a corrugated hose 29, and one end of the corrugated hose 29 is fixedly connected to the inner side of the annular auxiliary block 3. The inner side of the annular auxiliary block 3 and the outer wall of the sliding rod 24 are provided with a drainage aid. The inner side of the ventilation slot 10 is equipped with a humidity sensor 17, and the humidity sensor 17 is located between the two first filters 5. The inner side of the annular auxiliary block 3 is fixedly connected to the top of the annular piston block 21. The inner side of the sealing chamber 20 is installed below the annular piston block 21 with a first blocking block 19.

[0036] Firstly, a black film can be applied to the surface of the arc-shaped cover 35. Since the arc-shaped cover 35 is tilted upwards in an inward V-shape towards the upper shell 2, the tilted arc-shaped cover 35 can shield the instruments inside the assembled lower shell 1 and upper shell 2 from light, thereby reducing the reflection of sunlight shining from the side onto the upper shell 2, so that the user can observe them while riding.

[0037] After the lower shell 1 and upper shell 2 are assembled, the water level sensor 23, humidity sensor 17, miniature electric actuator 7 are electrically connected to the controller. When the lower shell 1 and upper shell 2 are installed on the electric bicycle, on sunny days, outside air can be filtered through the first filter 5 and the second filter 30 before entering the lower shell 1 and upper shell 2, allowing the heat generated by the internal equipment to exchange with the outside air for heat dissipation. When the user rides in the rain, the first blocking block 19 senses high humidity and activates the miniature electric actuator 7 via the controller. The output of the miniature electric actuator 7 drives the connecting plate 8, causing the connecting column 13 to move downwards. Subsequently, the second connecting spring 26 and the sliding rod 24 pull the annular piston block 21 downwards, thereby introducing the gas inside the sealed chamber 20 into the sealed air chamber through the air guide pipe 28. Inside the bladder 4, the sealing bladder 4 expands to seal the gap between the lower shell 1 and the upper shell 2. Simultaneously, the expansion of the sealing bladder 4 fills the space between the first filter screen 5 and the second filter screen 30, further improving the sealing effect between the lower shell 1 and the upper shell 2. When the output end of the micro electric push rod 7 stops running, the bottom of the annular piston block 21 abuts against the first blocking block 19. When the electric bicycle starts, the micro electric push rod 7, humidity sensor 17, and water level sensor 23 are powered on. When the humidity sensor 17 detects low humidity, the micro electric push rod 7 starts, and its output end resets. Through the cooperation of these multiple components, ventilation is achieved between the lower shell 1 and the upper shell 2 during sunny weather riding, and the lower shell 1 and the upper shell 2 are sealed during rainy weather riding, thus improving the overall practicality and service life of the device.

[0038] Example 2:

[0039] This embodiment includes all the technical features of Embodiment 1, and its distinguishing technical features are as follows: the drainage aid includes absorbent cotton 18 placed inside the retention trough 32, and the bottom of the absorbent cotton 18 is glued to the top of the annular piston block 21. A flow pipe 9 is fixedly connected to the inner side of the annular auxiliary block 3, and a circular piston block 27 is slidably connected to the inside of the flow pipe 9. A drain pipe 11 is fixedly connected to the drain outlet of the flow pipe 9. A water level sensor 23 is installed on the outside of the sliding rod 24. A through hole communicating with the corrugated hose 29 is opened on the top of the annular piston block 21. A fixing block 22 is installed inside the through hole. An inclined surface 31 is provided on the top of the annular auxiliary block 3 at the edge of the retention trough 32. The inner side of the absorbent cotton 18 is attached to the retention trough 32.

[0040] When the electric bicycle is placed outdoors and not started, rainwater flows into the gap between the lower shell 1 and the upper shell 2, wetting the absorbent cotton 18. The absorbent cotton 18 absorbs water, and the excess water can be guided into the retention groove 32 through the inclined surface 31. Since the absorbent cotton 18 becomes heavier after absorbing water, when the weight of the absorbent cotton 18 reaches a certain threshold, it will push the annular piston block 21 to move downward, so that the gas inside the sealing chamber 20 can enter the sealing airbag 4, so that the sealing airbag 4 can automatically expand, thereby sealing the gap between the lower shell 1 and the upper shell 2, thereby improving the overall sealing performance of the device and thus improving the overall practicality of the device.

[0041] The miniature electric actuator 7 has two strokes. When the miniature electric actuator 7 senses excessive moisture, it sends a signal to the controller. The controller will then control the miniature electric actuator 7 to move the annular piston block 21 to the top of the first blocking block 19, after which the miniature electric actuator 7 will stop. When the water level sensor 23 senses water, the output end of the miniature electric actuator 7 will pull the circular piston block 27 through the connecting column 13 to the bottom of the drain outlet of the flow pipe 9, after which the miniature electric actuator 7 will stop. The output end of the miniature electric actuator 7 can only be reset when the water level sensor 23 no longer senses water.

[0042] When the electric bicycle is placed outdoors and not started, and the absorbent cotton 18 absorbs excessive water that accumulates above the circular piston block 27, when the electric bicycle is started, the water level sensor 23 senses that there is too much water inside the corrugated hose 29 and sends a signal to the controller. The controller then controls the micro electric push rod 7 to start, causing the output end of the micro electric push rod 7 to drive the connecting plate 8 through the connecting column 13 to move the circular piston block 27 downward. When the annular piston block 21 is attached to the top of the first blocking block 19, the circular piston block 27 continues to move downward and separates from the sleeve 25, thereby pulling one end of the second connecting spring 26 to continue moving until the circular piston block 27 moves below the drain outlet of the flow pipe 9, so that the excess water on the top of the circular piston block 27 can be discharged to the outside through the drain pipe 11, thereby improving the drainage effect of the device.

[0043] Example 3:

[0044] This embodiment includes all the technical features of Embodiment 1. The distinguishing technical feature is that: the bottom of the sealing airbag 4 is provided with a return component for assisting the sealing airbag 4 in resetting. The return component includes a second placement groove 15 opened inside the annular auxiliary block 3. A loop frame 14 is slidably connected inside the second placement groove 15. A first connecting spring 16 is fixedly connected to the bottom of the loop frame 14. One end of the first connecting spring 16 is fixedly connected to the annular auxiliary block 3. The top of the loop frame 14 fits against the bottom of the sealing airbag 4. The inner side of the annular auxiliary block 3 is provided with an installation groove that matches the sealing airbag 4. The sealing airbag 4 is installed inside the installation groove. The inner side of the annular auxiliary block 3 is provided with a notch that communicates with the ventilation groove 10. The size of the notch matches the loop frame 14.

[0045] When the sealing airbag 4 inflates, it pushes the U-shaped frame 14 to compress the first connecting spring 16 and move it downwards. When the U-shaped frame 14 retracts into the second placement groove 15, the sealing airbag 4 can seal the gap between the first filter screen 5 and the second filter screen 30. When the annular piston block 21 resets and draws the air inside the sealing airbag 4 into the sealing chamber 20, the pressure of the sealing airbag 4 on the U-shaped frame 14 gradually decreases, so that the first connecting spring 16 pushes the U-shaped frame 14 to reset. The U-shaped frame 14 can push away the sealing airbag 4 that is stuck between the first filter screen 5 and the second filter screen 30, so as to avoid the sealing airbag 4 blocking the airflow between the first filter screen 5 and the second filter screen 30.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
