DETAILED DESCRIPTION

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0029] like Figure 1 and Figure 2 As shown, this embodiment provides a self-locking controller, including a main body 1, which is usually set to a cylindrical shape to facilitate multi-directional adjustment of self-locking; a PCB board and a pressure sensor welded on the PCB board are provided inside the main body 1, and the pressure sensor is used to detect the gas pressure of an external device and convert the external gas pressure value into a voltage value; wherein, the main body 1 can also be set to a cylindrical shape, a square column shape, or other shapes, which can be adjusted according to actual needs.

[0030] One end of the main body 1 is integrally formed with a self-locking structure for connecting with an external structure. The external structure may be a tank body of a vacuum gas storage tank for new energy equipment, or may be other structures.

[0031] The self-locking structure includes a self-locking connector 21 and an oblique thread 22 arranged on the self-locking connector 21, wherein the self-locking connector 21 is used to connect to an external structure, and the oblique thread 22 is used to achieve anti-slip self-locking of the connection position between the self-locking connector 21 and the external structure when the self-locking connector 21 is connected to the external structure.

[0032] In order to improve the self-locking effect, the oblique thread 22 is set as an imperial oblique thread; of course, it can also be set to other thread forms with similar effects; it should be noted that, in order to facilitate connection, the self-locking connector 21 is set to a truncated cone shape, and the end face area of ​​the self-locking connector 21 away from the main body 1 is smaller than the end face area of ​​the self-locking connector 21 close to the main body 1, so as to facilitate installation; of course, the self-locking connector 21 can also be set to other shapes according to actual needs, which will not be repeated here.

[0033] In particular, in order to further enhance the sealing of the connection, thread sealant may be applied to the oblique thread 22 during the installation process, especially when the self-locking connector 21 is connected to an external structure, so as to seal the oblique thread 22 .

[0034] For the convenience of installation, a mounting member 23 is provided between the self-locking connector 21 and the body 1 . The mounting member 23 is hexagonal in shape to facilitate tightening and installation using a hexagonal wrench.

[0035] Specifically, such as Figure 2 As shown, the bevel thread 22 is threadedly connected to the British bevel thread 22 nut on the tank body, and thread sealant is applied to the bevel thread 22, and the mounting piece 23 is tightened and fixed with a hexagonal wrench to achieve installation and fixation with the tank body, thereby having an anti-loosening self-locking function to avoid loosening caused by vibration during driving.

[0036] In addition, a conducting hole 24 is provided inside the self-locking connector 21, so that the vacuum gas storage tank is connected to the internal pressure chip to monitor the air pressure value in real time.

[0037] To achieve signal transmission, such as Figure 1 As shown, a four-core plug-in is provided at one end of the body 1 away from the self-locking structure, and the four-core plug-in is electrically connected to the body 1 through the wiring harness 4; a plurality of pinholes are provided on the four-core plug-in, and the pinholes are electrically connected to the wiring harness 4, thereby realizing the electrical connection between the four-core plug-in and the body 1; wherein, the pinholes are usually set to four, and of course, can also be set to two or more; when the pinholes are set to four, two of the pinholes are positive and negative poles, another pinhole is the positive pole of the vacuum pump, and the other pinholes are for signal transmission, so as to feed back the voltage value detected and converted by the internal pressure sensor to the vehicle control unit; it should be noted that the pinholes can also be set to pins, which are adjusted according to the wiring harness 4 and the actual use environment.

[0038] When the vehicle is powered on, the pressure sensor inside the body 1 detects the pressure value, and according to the preset pressure curve, converts the measured pressure value into the voltage value corresponding to the curve, and transmits it to the vehicle control unit through the signal pin of the wiring harness, and according to the preset control logic, controls the start and stop of the vacuum pump, and performs the alarm and protection functions, as follows:

[0039] A: Start the vacuum pump when the vacuum degree is ≤-50Kpa, and stop the vacuum pump when the vacuum degree is ≥-70Kpa;

[0040] B: When the vacuum pump works for ≥30 seconds, an alarm will be triggered. When it works for >60 seconds, the vacuum pump will be stopped and will automatically resume working after 10 seconds.

[0041] C: When the working current is greater than 15A, an alarm will be triggered. When the working current is greater than 18A and exceeds 2 seconds, the vacuum pump will stop working.

[0042] like Figure 1 As shown, the four-core plug-in includes:

[0043] The plug-in body 31 has a plurality of functional layer patterns 31 arranged on the circumference of the side of the plug-in body 31 to meet the use requirements of the plug-in body 31 in some environments;

[0044] The harness connector 32 is connected to the side of the plug-in body 31 close to the body 1 . The harness connector 32 is provided with a plurality of pinholes and is electrically connected to the harness 4 through the pinholes.

[0045] In order to facilitate the assembly of the plug-in body 31 with other structures, the plug-in body 31 is connected to a first functional component, the first functional component is located between the plug-in body 31 and the wiring harness 4 connector 32, and one end of the first functional component is fixedly connected to the plug-in body 31; generally, in order to facilitate the processing of the first functional component, a clearance space is provided between the plug-in body 31 and the wiring harness 4 connector 32 to facilitate the fixation of the first functional component.

[0046] Specifically, the first functional part includes:

[0047] A first connecting member 331, one end of the first connecting member 331 close to the plug-in body 31 is fixedly connected to the plug-in body 31 and is parallel to an end surface of the plug-in body 31 close to the main body 1;

[0048] One end of the first extending member 332 is fixedly connected to an end of the first connecting member 331 away from the plug-in body 31 . The first extending member 332 is perpendicular to the first connecting member 331 in the first state.

[0049] Since the first connecting member 331 is perpendicular to the first extending member 332 , there is a certain space between the first extending member 332 and the plug-in body 31 , thereby facilitating the installation and fixation of other equipment or the transportation of the plug-in body 31 .

[0051] The beneficial effects of the utility model are as follows:

[0052] The main body 1 is connected to the vacuum gas storage tank body through the self-locking structure 2, and is installed on the British oblique thread nut on the tank body. During installation, thread sealant is applied to the thread and tightened with a hexagonal wrench; at the same time, it is connected to the whole vehicle through a four-core plug-in. When the whole vehicle is powered on, the controller starts to work. When the vacuum degree is lower than the pressure value set by the control logic, the vacuum pump is started. When the vacuum degree is higher than the pressure value set by the control logic, the vacuum pump is stopped. When the vacuum pump works for more than the set continuous working time, an alarm is issued or the vacuum pump is stopped. When the working current is greater than the set current, an alarm is issued or the vacuum pump is stopped.
