Description

Technical Field

[0001] This utility model relates to the field of tipping protection technology, and in particular to a tipping protection device for electric bicycles. Background Technology

[0002] Electric bicycles, as a green mode of transportation, are widely favored by consumers. They utilize clean energy, effectively reducing environmental pollution and aligning with the national concept of green transportation. With the rapid development of electric bicycles, auxiliary devices are becoming increasingly common, such as lighting, horns, anti-theft devices, and displays. People also have higher performance requirements for electric bicycles. Therefore, electric bicycles are typically heavier than regular pedal bicycles, making them less stable when tipped over, increasing the risk of injury. Installing tipping protection devices on electric bicycles is therefore necessary to ensure safe use.

[0003] However, existing tipping protection devices are usually simple in structure and can only provide basic support when in use. They require operation by the user and are not convenient for timely response to bicycle tipping and protection, resulting in poor protection. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a tipping protection device for electric bicycles to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a tipping protection device for an electric bicycle, including a protective bracket fixedly installed with the electric bicycle. The protective bracket houses a protective main control unit that is signal-connected to the electric bicycle's control system. The protective main control unit is signal-connected to a tilt sensor that detects the degree of tipping of the electric bicycle. Protective drive rods are provided on both sides of the tilt sensor for driving. One end of each protective drive rod is rotatably connected to a retractable tipping protection frame. A high-strength sleeve for increasing strength is fixedly installed inside the tipping protection frame. A laser rangefinder sensor for detecting the edge height of the protective bracket is provided on one side of the tipping protection frame. A safety sleeve protecting the laser rangefinder sensor is provided on one side of the laser rangefinder sensor. A rotating seat for adjusting the angle of the laser rangefinder sensor is fixedly installed at one end of the laser rangefinder sensor.

[0006] Preferably, in any of the above embodiments, the two ends of the protective bracket are configured as inclined structures, the middle of the protective bracket is provided with a detection groove to accommodate the tilt sensor, and the bottom of the tilt sensor is fixedly installed with a mounting base for supporting and fixing it.

[0007] The above technical solution is adopted: the inclined structure at both ends of the protective bracket facilitates better fit and fixation with the frame of the electric bicycle, enhancing the stability of the connection. On the other hand, when the electric bicycle tipps over, it can guide the tipping protective bracket to unfold and support more smoothly. The detection groove in the middle of the protective bracket provides a precise installation position for the tilt sensor, ensuring that it can stably detect the tilt angle of the electric bicycle.

[0008] Preferably, in any of the above embodiments, the mounting base includes a supporting fixing plate, a fastening spring providing elasticity, and a locking mounting plate. The fixing plate and the tilt sensor are fixedly installed. The fixing plate is snapped into the interior of the protective bracket. Fastening springs are fixedly installed at both ends of the fixing plate, and one end of the fastening spring is fixedly installed inside the fixing plate.

[0009] The above technical solution is adopted: the mounting base at the bottom of the tilt sensor is tightly fixed to the sensor by a fixing plate, and the elasticity of the fastening spring is used to firmly lock the mounting plate into the protective bracket, ensuring the stability of the tilt sensor during daily riding, and facilitating disassembly, maintenance or replacement when needed, ensuring that the sensor is always in the best working condition, and providing a reliable guarantee for timely and accurate detection of the tilt degree of the electric bicycle.

[0010] Preferably, in any of the above embodiments, the protective drive rod includes a rotating seat for connection, a pneumatic telescopic rod for signal connection to the protective main control unit, and a supporting connecting seat. The rotating seat is rotatably connected to both ends of the protective bracket, one end of the rotating seat is fixedly connected to the pneumatic telescopic rod, and one end of the pneumatic telescopic rod is fixedly connected to the connecting seat.

[0011] The above technical solution involves the protective drive rod, controlled by the main control unit, which adjusts the tilt protection frame. The rotating connection between the rotating seat and both ends of the protective bracket allows the drive rod to rotate flexibly to adapt to different working angle requirements. Based on the tilt angle detected by the tilt sensor, the main control unit sends a command to the pneumatic telescopic rod. The pneumatic telescopic rod then moves the connecting seat through its extension and retraction. The rotating connection between the connecting seat and the tilt protection frame converts the linear motion of the pneumatic telescopic rod into the rotational motion of the tilt protection frame, enabling rapid deployment or retraction of the tilt protection frame. This provides timely support when the electric bicycle is about to tip over, effectively preventing the vehicle from tipping over and improving the safety of riding an electric bicycle.

[0012] Preferably, in any of the above embodiments, the tipping protection frame is rotatably connected to both ends of the protective support, and one end of the tipping protection frame is provided with a connecting boss that is rotatably connected to the connecting seat.

[0013] Preferably, in any of the above embodiments, the high-strength casing includes a high-strength spring providing support and a protective sleeve protecting the tipping protection frame. The high-strength spring is fixedly installed at one end of the tipping protection frame, and the protective sleeve, which is sleeved on the surface of the tipping protection frame, is fixedly installed at one end of the high-strength spring.

[0014] The above technical solution allows the tipping protection frame to rotate flexibly around the connection point under the drive of the protective drive rod. When the electric bicycle is in normal operation, the tipping protection frame is in a retracted state, close to the protective bracket, without affecting the normal operation of the vehicle. When a tipping tendency is detected, the protective drive rod drives the tipping protection frame to quickly unfold, supporting the electric bicycle. The high-strength springs act as a buffer during the unfolding process, reducing the impact force on the protection frame. The protective cover effectively prevents the tipping protection frame from being damaged when it comes into contact with the ground or is subjected to other external forces, extending its service life and ensuring that it can still maintain good protective performance after multiple uses, providing reliable tipping protection for electric bicycles.

[0015] Preferably, in any of the above embodiments, the rotating base includes a rotating motor connected to the main control unit and a rotating base for flipping. The rotating motor is fixedly installed inside the protective bracket, and a rotating base for rotating inside the protective bracket is fixedly installed at one end of the rotating motor. The laser rangefinder is fixedly installed inside the rotating base, and the safety sleeve is fixedly installed at both ends of the protective bracket.

[0016] The above technical solution employs a laser rangefinder sensor to accurately detect the distance between the edge of the protective bracket and the ground. A rotating motor, controlled by the main control unit, drives the tilting seat to rotate inside the protective bracket, thereby adjusting the detection angle of the laser rangefinder sensor. A safety sleeve protects the laser rangefinder sensor from damage caused by collisions or scratches during vehicle operation. The laser rangefinder sensor transmits the detected distance data to the main control unit, which, combined with data from the tilt sensor, comprehensively judges the degree of tipping of the electric bicycle. Through multi-angle and multi-parameter monitoring, the accuracy and timeliness of electric bicycle tipping detection are further improved, providing more comprehensive data support for timely protective measures and effectively enhancing the protective and stable performance of electric bicycles.

[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0018] 1. Install a protective bracket at the bottom of the electric bicycle, and install a tilt sensor inside the protective bracket to monitor the tilt angle of the electric bicycle in real time. Based on the tilt angle of the electric bicycle, control the protective drive rod to adjust the position of the tilt protection frame. The tilt protection frame and the protective bracket form a triangular structure to support the electric bicycle. At the same time, install a high-strength shell at the bottom of the tilt protection frame for protection, so as to facilitate timely detection and support when the electric bicycle tipps over, improve the protection and stability of the electric bicycle, and prevent the electric bicycle from tipping over.

[0019] 2. Rotary seats are installed at both ends of the protective bracket to adjust the detection angle of the tilt sensor. The rotating seats are used to drive the laser rangefinder sensor to adjust its direction, so that the laser rangefinder sensor can detect the distance between the protective bracket and the ground, thereby further monitoring the degree of tipping of the electric bicycle and improving the protection and stability of the electric bicycle.

[0032] The above technical solution is adopted: the inclined structure at both ends of the protective bracket 1 facilitates better fit and fixation with the frame of the electric bicycle, enhancing the stability of the connection. On the other hand, when the electric bicycle tipps over, it can guide the tipping protective bracket 4 to unfold and support more smoothly. The detection groove in the middle of the protective bracket 1 provides a precise installation position for the tilt sensor 2, ensuring that it can stably detect the tilt angle of the electric bicycle.

[0033] Preferably, the mounting base 9 includes a supporting fixing plate 91, a spring 92 providing elasticity, and a mounting plate 93 for engaging.

Springs 92 are fixedly installed at both ends of the fixing plate 91, and one end of the spring 92 is fixedly installed inside the fixing plate 91.

[0034] The above technical solution is adopted: the mounting base 9 at the bottom of the tilt sensor 2 is tightly fixed to the sensor by the fixing plate 91, and the elastic force of the fastening spring 92 is used to firmly lock the mounting plate 93 into the protective bracket 1, which ensures the stability of the tilt sensor 2 during daily riding, and facilitates disassembly, maintenance or replacement when needed, ensuring that the sensor is always in the best working condition, and providing a reliable guarantee for timely and accurate detection of the tilt degree of the electric bicycle.

[0035] Preferably, the protective drive rod 3 includes a rotating seat 31 for connection, a pneumatic telescopic rod 32 for signal connection to the protective main control unit, and a connecting seat 33 for support. The rotating seat 31 is rotatably connected to both ends of the protective bracket 1. One end of the rotating seat 31 is fixedly connected to the pneumatic telescopic rod 32, and one end of the pneumatic telescopic rod 32 is fixedly connected to the connecting seat 33.

[0036] The above technical solution is adopted: Under the control of the main control unit, the protective drive rod 3 can drive and adjust the tipping protection frame 4. The rotating seat 31 is rotatably connected to both ends of the protective bracket 1, so that the protective drive rod 3 can rotate flexibly to adapt to different working angle requirements. According to the tilt angle information detected by the tilt angle sensor 2, the main control unit sends a command to the pneumatic telescopic rod 32. The pneumatic telescopic rod 32 drives the connecting seat 33 to move through the telescopic action. The rotating connection between the connecting seat 33 and the tipping protection frame 4 can convert the linear motion of the pneumatic telescopic rod 32 into the rotational motion of the tipping protection frame 4, so as to realize the rapid deployment or storage of the tipping protection frame 4. It can provide timely support at the moment when the electric bicycle is about to tip over, effectively prevent the vehicle from tipping over, and improve the safety of riding the electric bicycle.

[0037] Preferably, in any of the above schemes, the tipping protection frame 4 is rotatably connected to both ends of the protection bracket 1, and one end of the tipping protection frame 4 is provided with a connecting boss that is rotatably connected to the connecting seat 33.

[0038] Preferably, in any of the above embodiments, the high-strength housing 5 includes a high-strength spring 51 that provides support and a protective sleeve 52 that protects the tipping protection frame 4. The high-strength spring 51 is fixedly installed at one end of the tipping protection frame 4, and the protective sleeve 52 that is sleeved on the surface of the tipping protection frame 4 is fixedly installed at one end of the high-strength spring 51.

[0039] The above technical solution allows the tipping protection frame to rotate flexibly around the connection point under the drive of the protective drive rod 3. When the electric bicycle is in normal operation, the tipping protection frame 4 is in a retracted state, close to the protective bracket 1, without affecting the normal operation of the vehicle. When a tipping tendency is detected, the protective drive rod 3 drives the tipping protection frame 4 to quickly unfold, supporting the electric bicycle. The high-strength spring 51 acts as a buffer during the unfolding process of the tipping protection frame 4, reducing the impact force on the protection frame.

[0040] Preferably, in any of the above schemes, the rotating seat 8 includes a rotating motor 81 connected to the main control unit signal and a rotating seat 82 for flipping.

[0042] The working principle of the tipping protection device for electric bicycles of this utility model is as follows:

[0043] When the electric bicycle is in motion, the tilt sensor 2 monitors the vehicle's tilt angle in real time. During normal operation, the protective drive rod 3 is in a retracted state, and the tilt protection frame 4 is stored on both sides of the protective bracket 1. When the tilt sensor 2 detects that the vehicle's tilt angle reaches a preset value, the main control unit controls the pneumatic telescopic rod 32 to extend, pushing the connecting seat 33, causing the tilt protection frame 4 to unfold around the connection point with the protective bracket 1. At the same time, the rotating motor 81 rotates the flipping seat 82 as needed, adjusting the angle of the laser rangefinder sensor 6 to measure the distance between the edge of the protective bracket 1 and the ground, assisting in judging the degree of tilt. If the vehicle continues to tilt, the tilt protection frame 4 and the protective bracket 1 form a triangular support structure, and the high-strength shell 5 enhances the support stability and prevents the vehicle from tilting. After the vehicle returns to normal, the main control unit controls all components to reset, and the laser rangefinder sensor 6 continues to monitor to ensure riding safety.

At the same time, a high-strength sleeve 5 is installed at the bottom of the tilt protection frame 4 for protection, so as to facilitate timely detection and support when the electric bicycle tilts, improve the protection and stability of the electric bicycle, and prevent the electric bicycle from tilting.

[0046] 2. Rotary seats 8 are set at both ends of the protective bracket 1 to adjust the detection angle of the tilt sensor 2. The rotating seats 8 are used to drive the laser rangefinder 6 to adjust its direction, so that the laser rangefinder 6 can detect the distance between the protective bracket 1 and the ground, further monitoring the degree of tipping of the electric bicycle, which is conducive to further improving the protection and stability of the electric bicycle.
