Description

Technical Field

[0001] The utility model belongs to the technical field of storage batteries, and in particular relates to a liquid replenishment control device for a storage battery monomer of a rail transit vehicle. Background Art

[0002] The battery system is the power source for vehicle starting and emergency DC power supply, and is a key system to ensure the safe operation of the train. In order to ensure that the battery pack is in good working condition, the safety inspection of the battery cell is particularly important. The balanced maintenance team needs to check the appearance and liquid level of the battery cell during each maintenance process. When the liquid level of the battery cell is too low, it needs to be refilled to ensure the safety and reliability of the equipment.

[0003] The commonly used method of replenishing liquid usually uses a contact liquid level sensor to measure the liquid level of a single battery and uses a self-priming water pump to add liquid to the battery. It is mainly composed of a water pump controller, a water pump, a water level sensing probe, a filling button, a filling tube and other components. However, the contact liquid level sensor is usually directly connected to an alarm device to realize the detection of the liquid level. The operator needs to operate the water pump controller according to the alarm situation. There is a lack of control device between the contact liquid level sensor and the water pump controller and the contact liquid level sensor. There is a delay in the operation, and the operation steps are cumbersome and inconvenient, which is not conducive to improving the automation degree and replenishment efficiency of the replenishment process. Therefore, a control device is required to realize the detection of the liquid level and connect and communicate with the water pump controller.

[0004] Since the refilling of the vehicle battery system often requires moving and adjusting with the vehicle maintenance position, the existing control device lacks a support mechanism that is easy to operate, resulting in the control device being easily infiltrated with water or damaged when placed randomly. The lack of a support mechanism also makes it inconvenient for operators to use the control device. Utility Model Content

[0005] In view of this, the utility model aims to propose a rail transit vehicle battery cell refill control device to solve the problem that the existing control device lacks a support mechanism that is easy to operate and is inconvenient to operate when applied to the refill control of the vehicle battery system.

[0006] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0008] The device body comprises a shell and a main control module arranged in the shell, and the shell is provided with a display module, a key module, an alarm module and an interface module connected to the main control module;

[0009] The support mechanism includes a support frame, one end of which is arranged on the shell, and the other end is provided with an upper inclined surface and a lower inclined surface, the angle between the upper inclined surface and the lower inclined surface is a right angle or an obtuse angle, a support plate is provided on the lower inclined surface, and the support plate is rotatably installed on the support frame toward one end of the upper inclined surface, the lower inclined surface is provided with an assembly groove that cooperates with the support plate, and the upper inclined surface is provided with a positioning component for positioning the support plate.

[0011] Furthermore, the interface modules include KH-TYPE-C-16P, CH340C, and HC-RJ45-053-5.

[0012] Furthermore, a power module is also provided on the shell, and the main control module, display module, key module, alarm module, and interface module are all connected to the power module to realize power supply.

[0013] Furthermore, an anti-skid pad is provided on the support plate, one end of the anti-skid pad is arranged on the support plate, and the other end extends out of the assembly groove.

[0014] Furthermore, a counterweight block is provided on one side of the support plate facing the lower inclined surface portion, and a receiving groove for receiving the counterweight block is provided on the lower inclined surface portion, and the receiving groove is communicated with the assembly groove.

[0015] Furthermore, a magnetic attraction piece is provided at a position on the lower inclined surface portion corresponding to the accommodating groove, and a magnetic attraction portion capable of cooperating with the magnetic attraction piece is provided on the counterweight block.

[0016] Furthermore, at least two magnetic suction parts are evenly arranged around the corresponding counterweight block.

[0017] Furthermore, the positioning assembly includes an insert block slidably mounted on the upper inclined surface portion, and one end of the support plate facing the upper inclined surface portion is provided with a slot that can cooperate with the insert block.

[0018] Compared with the prior art, the rail transit vehicle battery monomer refilling control device described in the utility model has the following advantages:

[0019] (1) The rail transit vehicle battery monomer refilling control device described in the utility model has the advantages of simple structure, flexible and convenient use, good applicability, high safety and reliability. By arranging a support mechanism on the device body and using the support mechanism to support and elevate the device body, it is helpful to reduce the impact of residual liquid on the ground or the operating table on the internal components of the device body, reduce the possibility of residual liquid entering the device body, and improve the safety and reliability of the device when in use.

When the support plate is received into the assembly slot, the lower inclined surface can stably support the device body under the action of the counterweight, and the device body is not easy to move. When the support plate is rotated out of the assembly slot and the device body is supported by the support plate, the counterweight can still play a good stabilizing role on the support plate and the support frame. At this time, the center of gravity of the entire control device moves downward, which is beneficial to improve the stability of the control device when it is placed vertically.

[0036] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0037] A rail transit vehicle battery monomer refilling control device, such as Figures 1 to 9As shown, it includes a device body and a supporting mechanism arranged on the device body.

[0038] The device body comprises a housing 1 and a main control module 20 arranged in the housing 1 . The housing 1 is provided with a display module 5 , a button module 3 , an alarm module 4 , and an interface module 6 connected to the main control module 20 .

[0039] Optionally, the main control module 20 includes ESP32-WROOM-32. Exemplarily, the display module 5 can adopt a display screen, which can be installed on the housing 1 or directly on the circuit board 19 of the main control module 20. A window is provided at a position corresponding to the display screen on the housing 1 to facilitate operators to view the display screen. Secondly, the button module 3 can adopt existing buttons. Similarly, the buttons can be installed on the housing 1 or directly on the circuit board 19 of the main control module 20. A mounting hole is provided at a position corresponding to the button on the housing 1 to facilitate operators to operate the buttons to realize the operation of the control device, which will not be repeated here. Those skilled in the art can also select suitable display modules 5 and button modules 3 according to actual needs, and select suitable methods for assembly according to actual needs, which will not be repeated here.

[0040] Optionally, the alarm module 4 can use a buzzer and be directly installed on the circuit board 19 of the main control module 20. The installation and power supply methods of the buzzer are all existing technologies and will not be repeated here. In actual use, the alarm module 4 can be used to alarm and remind the operator that the rehydration is completed, which is conducive to improving the efficiency of rehydration.

[0041] In actual application, the ESP32 main control chip is used as the calculation control chip, and the IO interface can be expanded to realize multiple types of control; the data can be displayed intuitively through the display interface, and the addition of a flow meter module can calculate the amount of liquid added according to the flow rate.

[0042] The specific operation process can refer to the following steps: first, click the start button and the main control module 20 receives the start signal and starts the detection water pump. The liquid level sensor detects the liquid level status in real time. If it is prompted that the liquid level cannot be detected, the operator can double-click the start button to start the liquid adding water pump. When the required liquid level is reached, it will automatically stop and the buzzer will alarm. The two water pumps and the buzzer are driven by the UL2003 chip issued by the main control module 20, and then the UL2003 drives the intermediate relay to control the start and stop of the pump. The display screen can display data through the I2C protocol.

[0043] Optionally, the interface module 6 includes KH-TYPE-C-16P, CH340C, and HC-RJ45-053-5. Among them, KH-TYPE-C-16P can be used as a charging and data transmission interface. KH-TYPE-C-16P is connected to CH340C to download programs to ESP32-WROOM-32 in the main control module 20, so that the program can be quickly loaded. HC-RJ45-053-5 can be used as a network port to establish communication with the water pump controller. Those skilled in the art can also choose other suitable interfaces according to actual needs, which will not be repeated here. By setting up a variety of interfaces, it is convenient for the control device to load programs and facilitate communication between the control device and the water pump controller, thereby improving the flexibility and applicability of the use of such a control device.

[0044] The housing 1 is also provided with a power module, and the main control module 20, the display module 5, the key module 3, the alarm module 4, and the interface module 6 are all connected to the power module to realize power supply. Exemplarily, the power module includes a 18650 lithium battery and an IP5306 (U5) battery management chip, wherein a battery compartment for installing the 18650 lithium battery can be provided on the housing 1, and a detachable cover plate 17 is provided at the position corresponding to the battery compartment, and the cover plate 17 can be fixed to the housing 1 by screws.

[0045] In actual application, when charging, the 18650 lithium battery can be charged through the KH-TYPE-C-16P interface and the IP5306 (U5) battery management chip. It can power the lower loads while charging and use four LED lights to display the power. After charging, the 18650 lithium battery powers the lower loads. In addition, the power module can also include an AMS1117-3.3V voltage regulator chip to provide a 3.3V power supply to the circuit board 19 of the main control module 20. Those skilled in the art can also select other suitable power modules for power supply according to actual needs, which will not be repeated here.

[0046] The above-mentioned supporting mechanism includes a supporting frame 2, one end of which is arranged on the shell 1, and the other end is provided with an upper inclined surface 7 and a lower inclined surface 8, the angle between the upper inclined surface 7 and the lower inclined surface 8 is a right angle or an obtuse angle, and a supporting plate 12 is provided on the lower inclined surface 8, and the supporting plate 12 is rotatably installed on the supporting frame 2 toward one end of the upper inclined surface 7, and the lower inclined surface 8 is provided with an assembly groove 14 that cooperates with the support plate 12, and the upper inclined surface 7 is provided with a positioning component for positioning the support plate 12.

[0047] Exemplarily, the support frame 2 can be fixed on the housing 1 by screws. Those skilled in the art can also choose other suitable ways to install the support frame 2 according to actual needs to achieve stable assembly of the support frame 2 on the housing 1, which will not be repeated here. By providing a lower inclined surface 8 on the support frame 2, when the lower inclined surface 8 is used to support the device body, the device body can be placed at a relatively large angle, which is convenient for operators to operate the device body.

[0048] In actual application, the length of the lower bevel can be greater than the length of the upper bevel, so that when the device body is placed horizontally, the lower bevel can be used to directly support the device body, thereby avoiding the device body from being inverted due to misoperation. The upper bevel supports the device body, making it convenient for the operator to operate the device body. In addition, when the operator needs to place the device body vertically for easy operation, the operator can also rotate the support plate 12 first, so that the support plate 12 is rotated out of the assembly groove 14 and flush with the upper bevel. At this time, the support plate 12 can support the device body under the limit of the positioning component, and the device body can be placed vertically, which is convenient for the operator to operate. By providing the lower bevel portion 8 and providing a rotatable support plate 12 on the lower bevel portion 8, the flexibility and applicability of the support mechanism are improved, and it can be conveniently adjusted according to the needs of the operator to meet the placement needs of the device body at different angles.

[0049] Compared with the prior art, by arranging a support mechanism on the device body and using the support mechanism to support and elevate the device body, it is helpful to reduce the impact of residual liquid on the ground or the operating table on the internal components of the device body, reduce the possibility of residual liquid entering the device body, and improve the safety and reliability of the device when in use.

[0050] Optionally, the support plate 12 is provided with an anti-skid pad 13, one end of the anti-skid pad 13 is arranged on the support plate 12, and the other end extends out of the assembly slot 14. Exemplarily, the support plate 12 can be rotatably mounted on the support frame 2 via a rotating shaft, and a shaft hole for mounting the rotating shaft is provided at a position corresponding to the assembly slot 14 on the support frame 2. Those skilled in the art can also select other ways to install the support plate 12 according to actual needs, so as to achieve stable rotation of the support plate 12 on the support frame 2.

[0051] In actual application, the anti-skid pad 13 can be made of rubber material and fixed on the support plate 12 by adhesive or screws, and one end of the anti-skid pad 13 is installed on the support plate 12, and the other end extends to the end of the support plate 12, so that when the support plate 12 is used to support the device body, the anti-skid pad 13 can still play a good anti-skid limiting role on the support plate 12. By providing an assembly groove 14 for accommodating the support plate 12 on the lower inclined surface 8 of the support frame 2, the support plate 12 can be stably stored, and the support plate 12 can be prevented from being damaged due to collision during the movement of the device, which is conducive to improving the reliability of the device when in use.

[0052] Optionally, a counterweight 18 is provided on the side of the support plate 12 facing the lower inclined surface 8, and a receiving groove for receiving the counterweight 18 is provided on the lower inclined surface 8, and the receiving groove is connected to the assembly groove 14. Exemplarily, the counterweight 18 can be fixed on the support plate 12, and can also be fixed on the support plate 12 by screws. By arranging the counterweight 18 on the support plate 12, when the support plate 12 is received in the assembly groove 14, under the action of the counterweight 18, the lower inclined surface 8 can stably support the device body, and the device body is not easy to move. When the support plate 12 is rotated out of the assembly groove 14 and the support plate 12 is used to support the device body, the counterweight 18 can still play a good stabilizing role on the support plate 12 and the support frame 2, and at this time the center of gravity of the entire control device moves downward, which is conducive to improving the stability of the control device when it is placed vertically.

[0053] Optionally, a magnetic member 16 is provided at a position corresponding to the receiving groove on the lower inclined surface 8, and a magnetic portion that can cooperate with the magnetic member 16 is provided on the counterweight 18. Exemplarily, the magnetic member 16 can be a magnet or magnetic steel, and the magnetic member 16 can be fixed to the support frame 2 by screws or adhesives, and a mounting groove for mounting the magnetic member 16 can be provided on the support frame 2. Among them, the counterweight 18 can be made of iron or steel material, and an iron block or a steel block can also be fixed on the counterweight 18. Those skilled in the art can also choose other suitable ways to set the magnetic portion according to actual needs, so as to achieve the cooperation between the magnetic portion and the magnetic member 16, so that the counterweight 18 can remain stable under the cooperation between the magnetic portion and the magnetic member 16.

[0054] In actual use, by setting a magnetic attraction part 16 at a position corresponding to the accommodating groove on the lower inclined surface part 8, and setting a magnetic attraction part on the counterweight block 18, the counterweight block 18 and the support plate 12 can be stably stored by cooperating with the magnetic attraction part, thereby preventing the support plate 12 from rotating accidentally during the movement of the device.

[0055] Optionally, at least two magnetic members 16 are evenly arranged around the counterweight 18. By arranging the magnetic members 16 around the counterweight 18, it is not only beneficial to improve the stability of the magnetic members 16 adsorbing the counterweight 18, but also convenient for the operator to rotate and open the support plate 12, preventing the concentration of magnetic attraction from increasing the difficulty of rotating and opening the support plate 12.

[0056] Optionally, the positioning assembly includes an insert block 9 slidably mounted on the upper inclined surface 7, and the end of the support plate 12 facing the upper inclined surface 7 is provided with a slot 11 capable of cooperating with the insert block 9. Exemplarily, a slide groove 15 cooperating with the insert block 9 is provided at a position corresponding to the upper inclined surface 7 on the support frame 2, and the slide groove 15 is provided with an opening on one side of the support plate 12.

[0057] In actual application, the slide 15 can be a T-slot, and the handle 10 can be fixed on the plug 9. One end of the handle 10 is fixed on the plug 9, and the other end extends out of the slide 15. The operator can use the handle 10 to conveniently operate the plug 9 to move. When the support plate 12 rotates to be flush with the upper inclined surface 7, the operator can slide the plug 9 downward so that the plug 9 is inserted into the slot 11 on the support plate 12, thereby realizing the limited fixation of the support plate 12. Conversely, when the support plate 12 needs to be rotated and stored, the operator can also slide the plug 9 upward. After the contact plug 9 cooperates with the slot 11, the support plate 12 can be reset, and the magnetic suction part 16 is used to cooperate with the magnetic suction part on the counterweight 18 to realize the storage of the support plate 12, which is very simple to operate.

[0058] The utility model discloses a rail transit vehicle battery monomer refilling control device, which has the advantages of simple structure, flexible and convenient use, good applicability, high safety and reliability. By arranging a support mechanism on the device body and using the support mechanism to support and elevate the device body, it is helpful to reduce the influence of residual liquid on the ground or the operating table on the internal components of the device body, reduce the possibility of residual liquid entering the device body, and improve the safety and reliability of the device when in use. In addition, by arranging a counterweight on the support plate, when the support plate is stored in the assembly groove, under the action of the counterweight, the lower inclined surface can stably support the device body, and the device body is not easy to move. When the support plate is rotated out of the assembly groove and the support plate is used to support the device body, the counterweight can still play a good stabilizing role on the support plate and the support frame, and at this time, the center of gravity of the entire control device moves downward, which is helpful to improve the stability of the control device when it is placed vertically.
