[0043] like Figure 1-Figure 3 As shown, a battery detection device (hereinafter referred to as "detection device") provided by the embodiment of the present invention includes a shell 1, a plug-in component 2 and a moving component 3, wherein a driving component 11 is provided in the shell 1; the plug-in component 2 is inserted into the shell 1, one end of the plug-in component 2 is connected to the battery 6, and the other end is connected to the load or detection component 5; the moving component 3 can be selectively connected to the driving component 11 in transmission, and includes a first moving component 31 and a second moving component 32, wherein the first moving component 31 drives the plug-in component 2 to move in a first direction, so that the plug-in component 2 is connected to or disconnected from the load or detection component 5, and the second moving component 32 drives the plug-in component 2 to move in a second direction, so that the plug-in component 2 moves between the load and the detection component 5.

[0044] The housing 1 is used to carry the drive assembly 11, the plug assembly 2 and the moving assembly 3 arranged inside, so that the detection device is more convenient to move and install. The detection device can be arranged on the battery 6 or on one side of the battery 6 through the housing 1, so that the detection device can detect the state of the battery 6 at any time. When detection is required, the battery 6 can be switched from the use state to the detection state by remotely controlling the drive assembly 11, thereby reducing the labor intensity of manual detection and improving the detection efficiency.

[0045] One end of the plug assembly 2 is located outside the housing 1 so as to be connected to the battery 6, and the other end is located inside the housing 1, and is driven by the moving assembly 3 to selectively connect the interface of the load or detection assembly 5. Preferably, an avoidance groove can be provided on the housing 1 so that the plug assembly 2 can move through the housing 1. The interface of the load and detection assembly 5 can be provided on one side of the housing 1 to facilitate the connection of the plug assembly 2. According to the need of the moving position of the plug assembly 2, the driving assembly 11 can be selectively connected to the first moving assembly 31 or the second moving assembly 32 to achieve movement in different directions.

[0046] When the battery 6 needs to be tested, the driving component 11 is controlled to be connected to the first moving component 31 in transmission, so that the plug-in component 2 is first disconnected from the load interface, and then the driving component 11 is controlled to be connected to the second moving component 32 in transmission, so that the plug-in component 2 moves to a position relative to the detection component 5, and the first moving component 31 is driven again, so that the plug-in component 2 is connected to the interface of the detection component 5, and the state of the battery 6 can be detected. It can be understood that in other embodiments, the driving component 11 can drive the first moving component 31 and the second moving component 32 at the same time, so as to make the movement efficiency of the plug-in component 2 higher. By connecting the plug-in component 2 in the housing 1 to the battery 6, the driving component 11 is remotely controlled to move the plug-in component 2 to connect with the detection component 5, so as to realize the timely detection of the state of the battery 6. The detection device can remotely realize the conversion of the battery 6 to the terminal device, which is convenient for timely detection of parameters such as the internal resistance of the battery 6 and online monitoring of the state of the battery 6.

[0047] Optionally, the driving component 11 includes a motor 111 and a first gear 112. The motor 111 and the first gear 112 are connected via a first connecting member 113. The first connecting member 113 is telescopically arranged so that the first gear 112 can move under the action of the limit member 4 to selectively connect to the first movable component 31 or the second movable component 32.

[0048] The first connecting member 113 may include an outer set and an inner set to achieve a retractable setting. Under the action of the limiter 4, the first gear 112 is initially moved by the extension and retraction of the first connecting member 113. The parts of the first moving assembly 31 and the second moving assembly 32 that are transmission-connected to the first gear 112 are respectively located on both sides of the first gear 112, so that the first gear 112 can be selectively connected to the first moving assembly 31 or the second moving assembly 32 by movement. The cross-section of the first connecting member 113 is preferably rectangular, so that the rotation output by the motor 111 can be transmitted to the first gear 112, thereby reducing the decrease in transmission efficiency caused by the relative rotation of the outer set and the inner set.

[0049] Alternatively, if Figure 1-Figure 4 As shown, the first moving component 31 includes a second connecting member 311, one end of the second connecting member 311 is rotatably connected to an end of the first gear 112 away from the motor 111, and the other end of the second connecting member 311 is connected to the plug-in component 2. An elastic member 3111 is provided in the second connecting member 311 to reset the first gear 112 after it is away from the limit member 4.

[0050] The second connecting member 311 can be connected to the first gear 112 through a bearing or the like, so that the movement of the first gear 112 can drive the movement of the second connecting member 311, but the second connecting member 311 does not rotate with the first gear 112. After the first gear 112 is connected to the first moving component 31 by transmission, the elastic member 3111 in the second connecting member 311 can enable the first gear 112 to be reset to the state of transmission connection with the second moving component 32 after being away from the limit member 4. The first moving component 31 is activated by the movement of the first gear 112 along the first direction, so as to push the plug-in component 2 to connect with the detection component 5 or the load.

[0051] Optionally, the second connecting member 311 includes an outer sleeve 3112 and an inner sleeve 3113 , the outer sleeve 3112 is slidably connected to the inner sleeve 3113 , and two ends of the elastic member 3111 are respectively connected to the inner walls of the end portions of the outer sleeve 3112 and the inner sleeve 3113 .

[0052] Preferably, a slide groove is provided in the outer sleeve 3112, and a sliding key is provided in the inner sleeve 3113 to match the slide groove, so that the outer sleeve 3112 and the inner sleeve 3113 are connected by sliding. The elastic member 3111 is preferably a spring, and the two ends of the elastic member 3111 are fixedly arranged on the inner walls of the ends of the outer sleeve 3112 and the inner sleeve 3113.

[0053] Optionally, the first moving component 31 also includes a slider 312 and a second gear 313. The slider 312 is connected to the shell 1. The slider 312 and the first gear 112 are connected via a connecting rod 315. The motor 111 is connected to the connecting rod 315 via a third connecting member 314. An external thread is provided at one end of the connecting rod 315 close to the slider 312, and the slider 312 is provided with an internal thread. The first gear 112 can drive the second gear 313 to rotate, so that the motor 111 moves along the first direction and pushes the plug-in component 2 to move.

[0054] The slider 312 is disposed on the inner wall of the housing 1 opposite to the detection component 5. In order to maintain stable operation, an auxiliary slider may also be disposed on the side of the motor 111 away from the connecting rod 315, so that the auxiliary slider is slidably connected to the third connecting member 314, so as to play a supporting role when the motor 111 moves along the first direction without affecting the movement. In this embodiment, the connecting rod 315 passes through the slider 312, the third connecting member 314 and the second gear 313 respectively, and the third connecting member 314 can move along the first direction with the connecting rod 315. After the first gear 112 is engaged with the second gear 313, the second gear 313 rotates to drive the connecting rod 315 to rotate, thereby causing the connecting rod 315 to rotate out of the slider 312, thereby driving the motor 111 to move, so that the plug-in component 2 at the end can be connected to the detection component 5 or the load.

[0055] Preferably, a limiting structure may be provided on the connecting rod 315 and slidably connected to the upper surface of the housing 1, so as to improve the stability of the second gear 313. The limiting structure may be a sleeve or a slider.

[0056] Optionally, the first moving component 31 also includes a first guide rail 316 and a guide rod 317, the first guide rail 316 is symmetrically arranged on both sides of the shell 1, both ends of the guide rod 317 are slidably arranged in the first guide rail 316, and the guide rod 317 is connected to the plug-in component 2, so that the plug-in component 2 moves along the first direction with the guide rod 317.

[0057] The guide rod 317 is provided with a clamping portion at both ends to cooperate with the first guide rail 316. The first guide rail 316 provides a guiding function for the guide rod 317, and the guide rod 317 provides a supporting function for the plug assembly 2, so that the plug assembly 2 located at the end of the second connector 311 can remain stable. The setting position of the guide rod 317 does not affect the transmission and movement of the first gear 112 and the second gear 313.

[0058] Alternatively, if Figure 1-Figure 5 As shown, the plug assembly 2 includes a fixing member 21 and a plug 22 . The fixing member 21 is provided with a through slot 211 , so that the guide rod 317 passes through the through slot 211 , and the plug 22 is sleeved in the fixing member 21 .

[0059] The power cord of the plug 22 can pass through the through hole 212 on the fixing member 21 , and the plug 22 is fixed to the end of the fixing member 21 away from the through slot 211 , so that the plug 22 can be inserted into the interface of the load or detection component 5 .

[0060] Alternatively, if Figure 1-Figure 6 As shown, the second movable component 32 includes a third gear 321 and a rack 322. The third gear 321 is connected to the second connecting member 311 through a fourth connecting member 323. The axis of the third gear 321 is perpendicular to the axis of the first gear 112. The rack 322 is fixed in the housing 1. One side of the third gear 321 is meshed with the first gear 112, and the other side is meshed with the rack 322, so that the second movable component 32 can move along the second direction.

[0061] The axis of the third gear 321 is perpendicular to the bottom surface of the housing 1. Preferably, the first gear 112 is a bevel gear so that the third gear 321 cooperates to realize transmission. Due to the setting of the fourth connecting member 323, the third gear 321 and the first gear 112 can move synchronously. The fourth connecting member 323 is U-shaped, with one end fixedly connected to the second connecting member 311 and the other end rotatably connected to the third gear 321. Since the rack 322 is fixed, the third gear 321 rotates and cooperates with the rack 322, so that the first gear 112 can move along the second direction, thereby driving the plug assembly 2 to move.

[0062] Optionally, the limiter 4 is disposed on two inner walls of the shell 1 , and the limiter 4 is provided with an inclined portion 41 , so that when the first gear 112 approaches, the inclined portion 41 can move the first gear 112 to extend the first connecting member 113 and disengage the third gear 321 from the rack 322 .

[0063] After the first gear 112 moves to the preset position along the second direction, the stopper 4 can push the first gear 112 to move through the inclined portion 41, so as to achieve transmission connection between the first gear 112 and the second gear 313. The stopper 4 can be arranged on the inner walls on both sides of the housing 1, respectively at the positions corresponding to the plug-in assembly 2 and the load and detection assembly 5.

[0064] Optionally, the second moving assembly 32 further includes a second guide rail 324 , and the slider 312 is slidably disposed in the second guide rail 324 .

[0065] In order to enable the slider 312 to stably move along the second direction, a second guide rail 324 is provided on the inner wall of the housing 1, so that the slider 312 can slide along the second direction, driving the third connecting member 314 and the motor 111 to move synchronously. Preferably, the auxiliary slider is also slidably connected to the second guide rail 324.

[0066] It can be understood that the shape and size of each part of the detection device can be determined according to actual needs.

[0067] like Figure 1-Figure 7 As shown, the detection component 5 includes a detection interface 51, and the battery 6 can be electrically connected to the detection interface 51 through the plug-in component 2. The detection component 5 also includes a voltage sensor 52, a current sensor 53, a temperature sensor 54, a controller 55 and a remote control unit 56. Among them, the detection interface 51 is electrically connected to the voltage sensor 52 and the current sensor 53, and the voltage sensor 52 and the current sensor 53 respectively detect the voltage information and current information of the battery 6, and input the acquired information into the controller 55. The internal resistance of the current state of the battery 6 can be obtained through the voltage and current information. The temperature sensor 54 is used to detect the temperature information of the battery 6 and input it into the controller 55. The remote control unit 56 can be connected to the control terminal so that the information acquired by the controller 55 can be sent to the terminal device, such as a computer or a mobile phone, to realize remote detection, monitor the state of the battery 6 in real time, improve the online rate of the distribution automation terminal equipment, and improve the operation and maintenance efficiency. In view of the fact that the functions realized by the detection component 5 can be realized by the existing technology, the specific structure of the detection component 5 is not repeated here.

[0068] The detection device can use an ARM processor to collect parameters such as the voltage, temperature, resistance, and charge and discharge status of the battery 6, and upload the collected information to the terminal device through the network or RS485, where RS485 has protection measures such as lightning protection. The detection device is installed near the battery 6 and is suitable for measuring the voltage, internal resistance, and temperature of a 12V single battery. It has two RJ11 communication ports, which can ensure that abnormal alarm information can be accurately transmitted to the operation and maintenance personnel, improve the operation and maintenance efficiency, and increase the online rate of the distribution automation terminal. The power supply and voltage measurement circuit has anti-reverse connection, overvoltage, and overcurrent protection, and the detection is stable and reliable; the external Hall sensor can also measure positive and negative bidirectional currents, and has strong applicability.

[0069] The detection device is small in size and light in weight. The housing 1 is a non-metallic shell, which further reduces the potential safety hazards that may occur during on-site use and can achieve high reliability and high precision requirements for on-site voltage, current and temperature monitoring of the distribution terminal battery 6.

[0070] Embodiment 2

[0071] This embodiment provides a battery detection device, which is basically the same as the battery detection device in the first embodiment, except that the structure of the limiter 4 is different.

[0072] The stopper 4 is arranged on the inner wall of the upper surface of the housing 1, and the stopper 4 is arranged along the second direction. The width of the stopper 4 at both ends close to the detection assembly 5 and the load is greater than the width of the middle part of the stopper 4, so that the stopper 4 can play a role in pushing the first gear 112 at both ends. The stopper 4 is arranged as an integral structure extending along the second direction, so that the first gear 112 can be limited when moving, reducing the possibility of deviation caused by the telescopic effect of the first connecting member 113 and the second connecting member 311 on both sides of the first gear 112, and ensuring the stable operation of the detection device.

[0073] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
