DETAILED DESCRIPTION

[0017] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. It is possible for a person skilled in the art to fully understand the present invention without the description of these details. In order to avoid confusing the essence of the present invention, known methods, processes, flows, components and circuits are not described in detail. In addition, it should be understood by a person of ordinary skill in the art that the drawings provided here are for illustrative purposes, and the drawings are not necessarily drawn to scale.

[0018] First, the definitions of terms and names used in this utility model are explained as follows:

[0019] "Bicycle" generally refers to a means of transportation that combines a traditional bicycle with electric assist technology. It can also be called an electric bicycle or an electric-assisted bicycle.

[0020] The "bicycle system" includes a composite system that integrates mechanical and electronic components to achieve efficient and smooth assisted riding through electronic control and mechanical transmission.

[0021] "End cap" refers to the battery terminal cover on an internal battery bicycle system, which is a cover used to protect the battery terminals from damage or environmental damage. The end cap can be located on the battery box or battery holder of the bicycle system, and is used to cover the positive and negative terminals of the battery module. For example: on an electric bicycle with an internal battery module, the battery module has an external charging socket, so there will be an end cap to cover this external charging socket to further protect the battery terminals. When the end cap covers the battery terminal, it means that the battery module is not in charging mode. When the end cap is away from the battery terminal, it means that the battery module may be about to enter charging mode.

[0022] See also Figure 1, a detection system for a bicycle can detect the connection state between the bicycle system and the battery module (hereinafter referred to as the detection system 1), and the detection system 1 includes a magnetic module 12, a sensing module 14 and a processing module 16. The magnetic module 12 is arranged on the bicycle system 1A, and the magnetic module 12 can be a magnet, a permanent magnet, an electromagnet or a magnetic component. The sensing module 14 is arranged on the battery module 1B, and is used to sense the movement state of the magnetic module 12 to generate an electrical signal, wherein the sensing module 14 can be a Hall sensor, and the Hall sensor can include a differential Hall sensor, a switch Hall sensor or an analog Hall sensor. The processing module 16 is arranged on the battery module 1B and connected to the sensing module 14. The processing module 16 is provided with a detection threshold value, and the processing module 16 obtains the electrical signal of the sensing module 14, and compares the electrical signal with the detection threshold value, and generates a normal connection signal when the electrical signal meets the detection threshold value, and generates an abnormal connection signal when the electrical signal does not meet the detection threshold value. That is, when the processing module 16 generates a normal connection signal, it means that the battery module 1B and the bicycle system 1A are connected and can transmit information or power. When the processing module 16 generates an abnormal connection signal, it means that the battery module 1B and the bicycle system 1A are not connected and cannot transmit information or power.

[0023] For example, when the sensing module 14 is a Hall sensor, when the Hall sensor is close to or away from the magnetic module 12, the Hall sensor generates an electrical signal change due to the Hall effect (that is, the magnetic field can be converted into voltage). Once the processing module 16 detects that the distance between the Hall sensor and the magnetic module 12 has changed, it can be determined whether the battery module 1B and the bicycle system 1A are normally connected or abnormally connected. For example: the processing module 16 is provided with a detection threshold value of 2 volts. The processing module 16 obtains the electrical signal of the Hall sensor and compares the electrical signal with the detection threshold value. When the electrical signal is greater than or equal to 2 volts, it means that the electrical signal meets the detection threshold value. The processing module 16 generates a normal connection signal. When the electrical signal is less than 2 volts, it means that the electrical signal does not meet the detection threshold value. The processing module 16 generates an abnormal connection signal. The above detection threshold value is only an example and is not limited to this. Therefore, the Hall sensor can monitor the change of magnetic field based on the Hall effect without designing additional circuits, thus overcoming the problems of the prior art that the wires must be installed, resulting in increased wire costs and difficult wire maintenance. The connection between the battery module 1B and the bicycle system 1A can be confirmed to ensure product stability and reliability, while also improving the efficiency and practicality of the assembly between the bicycle system 1A and the battery module 1B.

[0024] In other embodiments, the processing module 16 controls the battery module 1B to start the charge and discharge mode according to the normal connection signal, and the processing module 16 controls the battery module 1B not to start the charge and discharge mode according to the abnormal connection signal. When the processing module 16 detects the change of the electrical signal of the Hall sensor, it determines the connection status between the battery module 1B and the bicycle system 1A, and then controls the charging circuit, the discharging circuit and the charging and discharging process.

[0025] In other embodiments, the processing module 16 obtains the battery information of the battery module 1B, and the battery information includes information such as the voltage, current, and temperature of the battery module 1B.

[0026] See also Figure 1 and Figure 2 , the following describes how the detection system 1 detects the connection state of the bicycle system 1A and the battery module 1B. The magnetic module 12 can be set in the socket connector 30 of the bicycle system 1A, and the sensing module 14 and the processing module 16 are set in the plug connector 20 of the battery module 1B. In other embodiments, the magnetic module 12 can also be set in the plug connector of the bicycle system 1A, and the sensing module 14 and the processing module 16 are in the socket connector of the battery module. The socket connector 30 and the plug connector 20 are paired concepts, and the two correspond to each other and allow mutual connection. The socket connector 30 and the plug connector 20 are connected to each other and transmit the required power, data or information. During implementation, the positions of the socket connector 30 and the plug connector 20 can be designed according to requirements. Generally speaking, the battery module 1B of the electric bicycle can be installed on the frame by different assembly methods. Usually, the battery module 1B is installed inside the frame of the bicycle or under the frame, so that the battery module 1B is completely combined with the frame, and the battery module 1B is connected to the electromechanical system on the bicycle system 1A through the connection between the socket connector 30 and the plug connector 20. At this time, the detection system 1 of this embodiment can detect whether the battery module 1B and the bicycle system 1A are firmly connected or have been removed.

[0027] The magnetic module may be a permanent magnet 120, and the sensing module may be a Hall sensor 140. The permanent magnet 120 is disposed in the socket connector 30 of the bicycle system 1A, and the Hall sensor 140 and the processing module 16 are disposed in the plug connector 20 of the battery module 1B. Figure 2 The permanent magnet 120 and the Hall sensor 140 are indicated by dotted lines, thereby indicating that the permanent magnet 120 is buried inside the socket connector 30 and the Hall sensor 140 is buried inside the plug connector 20. Figure 2 Although not shown in the figure, those skilled in the art should understand that the processing module 16 can be disposed in the battery module 1B as a central processing unit and electrically connected to the sensing module 14 .

[0028] The Hall sensor 140 is used to convert the magnetic field change into the electrical signal change, and can monitor the position and movement of the permanent magnet 120. When the permanent magnet 120 on the socket connector 30 and the Hall sensor 140 on the plug connector 20 have relative movement or distance change, the Hall sensor 140 senses the change in the surrounding magnetic field, and then generates an electrical signal change, so that the connection state of the bicycle system 1A and the battery module 1B can be detected, and the physical line connection can be reduced. In addition, the detection method of the Hall sensor 140 includes a switch, a latch, or a linear sensor, but is not limited thereto.

[0029] See also Figure 3 , the second embodiment of the detection system provided by the utility model is introduced below. The difference between this embodiment and the first embodiment is that the detection system 1' of this embodiment further includes a light emitting module 18, and the number of magnetic modules is multiple, the number of sensing modules is multiple, wherein the magnetic modules include magnetic modules 122 and magnetic modules 124, and the sensing modules include sensing modules 142 and sensing modules 144, and the components that are the same as those in the first embodiment are not repeated here.

[0030] like Figure 3 As shown, the light-emitting module 18 is arranged in the battery module 1B' and is electrically connected to the processing module 16. The processing module 16 turns on the light-emitting module 18 according to a normal connection signal to output a light source. The processing module 16 turns off the light-emitting module 18 to stop outputting the light source when the electrical signal of the sensing module 142 or the sensing module 144 is not detected, or according to an abnormal connection signal.

[0031] The bicycle system 1A' may include an electromechanical system 102 and an end cover 104. The electromechanical system 102 generally refers to a system of mechanical components and electronic components on the electric bicycle. As mentioned above, the end cover 104 may be located on the battery box or battery bracket of the bicycle system 1A' to shield the battery terminals of the battery module 1B'.

[0032] In this embodiment, the magnetic module 122 is disposed on the electromechanical system 102, and the magnetic module 124 is disposed on the end cover 104. However, in actual applications, the positions of the electromechanical system 102 and the end cover 104 may have different positions or be combined according to different designs, so that the magnetic module can be disposed on one of the electromechanical system 102 and the end cover 104 of the bicycle system 1A' according to needs, or multiple magnetic modules can be disposed on the electromechanical system 102 and the end cover 104 respectively, but the present invention is not limited thereto.

[0033] If the positions of the electromechanical system 102 and the end cover 104 are different, the sensing module 142 and the sensing module 144 belong to two different positions. If the electromechanical system 102 and the end cover 104 are combined, one sensing module can be set. In this embodiment, the moving states of the magnetic modules 122 and 124 are sensed by the sensing modules 142 and 144 respectively, and corresponding electrical signals are generated according to the moving states of the magnetic modules 122 and 124. The processing module 16 is connected to the sensing module 142 and the sensing module 144 respectively to obtain the electrical signals of the sensing modules 142 and 144, and then it can be determined whether the connection between the battery module 1B' and the bicycle system 1A' is abnormal.

[0034] For example, there are many ways to charge the battery module 1B', such as an external charging socket or charging by removing the battery. For example, the external charging socket is generally used on an electric bicycle with a built-in battery, so this external charging socket will be covered by an end cover 104. When charging is required, the user must plug one end of the external charger into this socket, and then plug the other end of the external charger into a power socket to charge the battery module 1B'. Therefore, detecting the connection between the battery module 1B' and the end cover 104 will affect the function of the bicycle system 1A'. Therefore, the detection system 1' of this embodiment can effectively detect whether the connection between the battery module 1B' and the end cover 104 is normal. If the battery module 1B' is charged by removing the battery for charging, the user needs to open the frame, remove the battery module 1B' and connect it to the charger for charging. After charging, if the battery module 1B' is installed back on the frame, it will be connected to the electromechanical system 102 on the bicycle system 1A' through the connection seat / connector. At this time, the detection system 1' of this embodiment can be used to detect whether the battery module 1B' and the bicycle system 1A' are firmly connected or not yet connected.

[0035] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
