Description

Technical Field

[0001] The utility model relates to the technical field of module detector shells, in particular to a module detector shell with a charging function. Background Art

[0002] The MOBAD module is installed on each VCU module of the CTCS-300T type train control on-vehicle equipment. It contains a lithium battery inside, which is used to maintain the VCU module address and important parameters for calculation. When the MOBAD module is installed on the VCU unit, the MOBAD battery is in a state of being used and consumed. It is difficult to detect the remaining voltage and power of the MOBAD on-site during monthly maintenance, quarterly maintenance, and advanced repairs. When the remaining power of the internal battery is insufficient, problems such as parameter failure and address loss are likely to occur, resulting in the inability of VCU modules such as ATPCU, C2CU, TSG, and SDP to start and work normally, affecting train operation safety and disrupting transportation order.

[0003] Currently, the means for repairing and testing the MOBAD battery on-site are limited, and only the method of replacing the new battery can be used to solve the problem. Currently, the detection means for the replaced MOBAD battery are limited, and only the voltage of the battery can be measured with a multimeter, which cannot truly reflect the remaining power of the measured battery. This measure cannot achieve effective maintenance and cannot prevent the MOBAD battery with almost exhausted power from being used on the vehicle. Therefore, a module detector shell with a charging function is proposed. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art in the technical field without creative work belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1-5, the housing of the module detector with a charging function in this embodiment includes a main housing 1. Interface panels 2 and baffles 3 are respectively installed at both ends of the main housing 1 through bolts. A detection display unit 4 is embedded and installed on the upper end surface of the main housing 1. A plurality of installation cavities and screw holes are provided on the outer wall of the interface panel 2. A switching power supply 8, a USB input power interface 5, a Type-C power interface 6, and a DB-9 communication serial port 7 are respectively installed in the plurality of installation cavities. The switching power supply 8, the USB input power interface 5, the Type-C power interface 6, and the DB-9 communication serial port 7 are all connected to the interface panel 2. A protection unit 9 for protecting the switching power supply 8, the USB input power interface 5, the Type-C power interface 6, and the DB-9 communication serial port 7 is installed between the front side of the interface panel 2 and the main housing 1.

[0024] Such as Figures 1-3As shown in the figure, the shell structure of the module detector in the present utility model is similar to the existing shell structure of the module detector. The main improvement of the present utility model lies in detecting the power of the MOBAD battery and charging the MOBAD battery. In the present utility model, the switching power supply 8, the USB input power interface 5, the Type-C power interface 6 and the DB-9 communication serial port 7 are respectively installed in multiple installation cavities on the interface panel 2, and the USB input power interface 5, the Type-C power interface 6 and the DB-9 communication serial port 7 are fixed through the screw holes on the outer wall of the interface panel 2. Screw holes are also provided at the four corners of the interface panel 2 and the baffle 3. The interface panel 2 and the baffle 3 are respectively installed at both ends of the main housing 1 by using bolts to cooperate with the screw holes. An installation hole is also provided on the upper end surface of the main housing 1. The detection and display unit 4 is embedded and installed on the main housing 1 by using the installation hole. Since it is a common existing installation technology, it will not be introduced in detail here. When testing the MOBAD module, connect the DB-9 (female) communication serial port of the MOBAD module to the DB-9 communication serial port 7 on the interface panel 2. The DB-9 communication serial port 7 on the interface panel 2 is a male port, and the inside of the DB-9 communication serial port 7 is connected to the detection and display unit 4. Connect the MOBAD module to the detected load of the detection and display unit 4. Then use one end of a Type-C data cable to connect to a laptop (desktop computer, tablet, charging protector, etc. are all okay), and the other end to the Type-C power interface 6, or use one end of a USB data cable to connect to a laptop (desktop computer, tablet, charging protector, etc. are all okay), and the other end to the USB input power interface 5, then the power can be introduced. The two paths are independent of each other and are used as spares for each other. Only one of them needs to be introduced during use. Turn on the switching power supply 8, and the power is input from the Type-C power interface 6 or the USB input power interface 5 into the switching power supply 8. After the power comes out from the pins of the switching power supply 8, it reaches the positive and negative poles of the detection and display unit 4 for the detection and display unit 4 to work. The detection and display unit 4 detects the current voltage and remaining power of the detected MOBAD module, and charges the MOBAD module through the DB-9 communication serial port 7 by using the connected power. The overall structure is simple, the volume is small, it is convenient to charge the battery of the MOBAD module and detect the power, and it ensures the use of the MOBAD module.

[0025] Among them, the detection and display unit 4, the switching power supply 8, the USB input power interface 5, the Type-C power interface 6 and the DB-9 communication serial port 7 mentioned above can all be purchased on the market. They belong to mature technologies and have been fully disclosed, so they will not be repeated in the specification.

[0026] Such as Figure 3 、 4As shown, the main housing 1 includes an upper housing 11 and a lower housing 12. The detection and display unit 4 is embedded and installed on the upper housing 11. The interface panel 2 and the baffle 3 are respectively fixed to both ends of the upper housing 11 and the lower housing 12 by bolts. The main housing 1 is composed of the upper housing 11 and the lower housing 12. The interface panel 2 and the baffle 3 are installed at both ends of the upper housing 11 and the lower housing 12, thereby locking the upper housing 11 and the lower housing 12. The upper housing 11 and the lower housing 12 are detachable structures, which are convenient for processing and manufacturing, and are also convenient for installing and wiring the detection and display unit 4, the switching power supply 8, the USB input power interface 5, the Type-C power interface 6, and the DB-9 communication serial port 7.

[0027] As Figure 3 , 4 shown, dovetail bars 10 are fixedly connected to the bottom end of one side of the upper housing 11 and the top end of one side of the lower housing 12. Dovetail grooves 13 adapted to the dovetail bars 10 are provided at the corresponding positions of the bottom end of the other side of the upper housing 11 and the top end of the other side of the lower housing 12. The dovetail bars 10 are movably inserted into the dovetail grooves 13. The lower housing 12 and the upper housing 11 are connected by the insertion fit of the dovetail grooves 13 and the dovetail bars 10. The dovetail bars 10 on the upper housing 11 and the dovetail bars 10 on the lower housing 12 are respectively inserted into the dovetail grooves 13 of the other party, thereby realizing the connection between the upper housing 11 and the lower housing 12 and improving the sealing at the connection between the upper housing 11 and the lower housing 12.

[0028] As Figure 1 , 2 shown in FIGS. 4 and 5, the protection unit 9 includes first limit sleeve blocks 91 fixedly installed on the upper surface of the upper housing 11 and the bottom surface of the lower housing 12. A silica gel shielding sheet 93 is connected between the two first limit sleeve blocks 91. First sleeve holes 94 are provided at both ends of the silica gel shielding sheet 93. The first sleeve holes 94 are movably sleeved outside the first limit sleeve blocks 91. The silica gel shielding sheet 93 shields the USB input power interface 5, the Type-C power interface 6, and the DB-9 communication serial port 7. When not in use, the first sleeve holes 94 provided at both ends of the silica gel shielding sheet 93 are respectively sleeved outside the two first limit sleeve blocks 91. Then, the silica gel shielding sheet 93 uses its own elasticity to fit against the outer wall of the interface panel 2, shielding the USB input power interface 5, the Type-C power interface 6, and the DB-9 communication serial port 7, avoiding the phenomenon of dust entering and damaging the USB input power interface 5, the Type-C power interface 6, and the DB-9 communication serial port 7 when not in use, and improving the practicality.

[0029] As Figure 1 , 2As shown in FIGS. 5, the protection unit 9 further includes a silicone connecting piece 96 fixedly connected to the side wall of the silicone shielding piece 93. A rigid shielding cover 97 is fixedly installed on the inner wall of the silicone connecting piece 96. The rigid shielding cover 97 shields the switching power supply 8. The shape of the inner wall of the rigid shielding cover 97 is the same as the shape and size of the outer wall of the switching power supply 8 in the off state. When not in use, the silicone shielding piece 93 fits on the outer wall of the interface panel 2. By using the connection between the silicone connecting piece 96 and the silicone shielding piece 93, the rigid shielding cover 97 is sleeved on the outer wall of the switching power supply 8 in the off state, thereby maintaining the off state of the switching power supply 8, ensuring that when the external power supply is connected next time, the switching power supply 8 is in a power-off state first, avoiding electric shock. At the same time, the rigid shielding cover 97 restricts the switching power supply 8, so that when not in use, the switching power supply 8 will not be accidentally touched, avoiding damage caused by repeated switching due to accidental touch.

[0030] As Figure 1 , 2 , 5 shows that the protection unit 9 further includes a second limiting sleeve block 92 fixedly installed on the outer wall of the interface panel 2. The outer end side wall of the silicone connecting piece 96 is fixedly connected with a fixed silicone piece 98. A second sleeve hole 99 is formed through the outer wall of the fixed silicone piece 98. The second sleeve hole 99 is movably sleeved on the outer wall of the second limiting sleeve block 92. After the rigid shielding cover 97 is sleeved on the switching power supply 8, the second sleeve hole 99 on the fixed silicone piece 98 is sleeved on the outer wall of the second limiting sleeve block 92. The second limiting sleeve block 92 is used in cooperation with the fixed silicone piece 98 to limit the rigid shielding cover 97 so that it cannot be opened, improving the protection performance.

[0031] As Figure 5 shown, two extension openings 95 are formed in the inner walls of the first sleeve hole 94 and the second sleeve hole 99. The two extension openings 95 are symmetrically distributed. By using the extension openings 95, it is convenient for the first sleeve hole 94 and the second sleeve hole 99 to be respectively sleeved on the first limiting sleeve block 91 and the second limiting sleeve block 92, and it is also convenient to remove, improving the convenience of use.

[0032] Implementation steps in this embodiment: When it is necessary to test the MOBAD module, first remove the fixed silica gel sheet 98 and the silica gel shielding sheet 93 from the second limit sleeve block 92 and the first limit sleeve block 91 respectively. Then connect the DB-9 (female) communication serial port of the MOBAD module to the DB-9 communication serial port 7 on the interface panel 2. The DB-9 communication serial port 7 on the interface panel 2 is a male port, and the inside of the DB-9 communication serial port 7 is connected to the detection and display unit 4. Connect the MOBAD module to the detected load of the detection and display unit 4. Then use one end of the Type-C data cable to connect to a laptop (desktop computer, tablet, power bank, etc. are all acceptable), and the other end to the Type-C power interface 6. Or use one end of the USB data cable to connect to a laptop (desktop computer, tablet, power bank, etc. are all acceptable), and the other end to the USB input power interface 5 to introduce power. The two-way inputs are independent of each other and used as spares. Only one of them needs to be introduced during use. Turn on the switching power supply 8. The power is input into the switching power supply 8 from the Type-C power interface 6 or the USB input power interface 5. After the power comes out from the pins of the switching power supply 8, it reaches the positive and negative poles of the detection and display unit 4 for the detection and display unit 4 to work. The detection and display unit 4 detects the current voltage and remaining power of the detected MOBAD module, and charges the MOBAD module through the DB-9 communication serial port 7 with the connected power supply. After the detection of the MOBAD module is completed, respectively set the first set holes 94 opened at both ends of the silica gel shielding sheet 93 outside the two first limit sleeve blocks 91. Then, due to the elasticity of the silica gel shielding sheet 93 itself, it fits on the outer wall of the interface panel 2 to shield the USB input power interface 5, the Type-C power interface 6, and the DB-9 communication serial port 7. Then put the hard shielding cover 97 on the outer wall of the switching power supply 8 in the off state, and set the second set hole 99 on the fixed silica gel sheet 98 on the outer wall of the second limit sleeve block 92.
