[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0044] Embodiment 1:

[0045] This embodiment describes the structure and working principle of the tire pressure gun, specifically:

[0046] like Figure 1-Figure 3 As shown, the present invention provides a tire pressure gun for heavy-duty new energy vehicles, including a tire pressure gun 1, which is used for inflating a tire 2 during maintenance or servicing of a heavy-duty new energy vehicle. The tire 2 has a carcass 21, and a valve core 23 is arranged on the carcass 21. The tire pressure gun 1 is suitable for connecting with the valve core 23 to introduce external gas into the carcass 21;

[0047] The tire pressure gun 1 comprises a front shell 11, which is an injection-molded integral structure, and a rear cover 12 is clamped on the front shell 11. Both the front shell 11 and the rear cover 12 are provided with cavities, and after the front shell 11 and the rear cover 12 are clamped, an installation chamber is formed between the two.

[0048] At the same time, a PCB board 17 is fixedly installed inside the installation chamber, and the PCB board 17 is located near the front shell 11, and a display screen 16 is installed on the PCB board 17, and the display screen 16 is connected to the PCB board 17 by signal. It should be noted that a window (not marked in the figure) penetrating the display screen 16 is opened on the front shell 11, so that when the display screen 16 is installed, it can be at the window, so that the staff can check the working status of the tire pressure gun 1;

[0049] And multiple groups of buttons 18 are installed on the PCB board 17, and the multiple groups of buttons 18 protrude from the front shell 11 and are exposed to the outside, so as to facilitate the operation of the staff. In the present invention, the multiple groups of buttons 18 include unit conversion keys, air pressure plus and minus keys, a power key, a reset key, etc., so that the staff can operate according to their needs;

[0050] Continue to refer Figure 1-Figure 2 A battery 19 is installed at a position of the PCB board 17 away from the front shell 11. The battery 19 is used to power various electrical components. In the present invention, the battery 19 can be configured as a rechargeable battery so that the tire pressure gun 1 can be used repeatedly;

[0051] At the same time, a solenoid valve 110 is installed inside the installation chamber. The solenoid valve 110 is connected to the PCB board 17 by signal so as to control the opening and closing of the solenoid valve 110. A first joint 13 is connected to the solenoid valve 110 by a pipeline. The first joint 13 is used to communicate with external high-pressure gas to introduce the gas into the position of the solenoid valve 110.

[0052] The solenoid valve 110 is also connected to an air outlet pipe 14, which is used to discharge the high-pressure gas introduced by the first joint 13 when the solenoid valve 110 is opened. At the same time, the air outlet pipe 14 is connected to a second joint 15 at a position away from the solenoid valve 110, and the second joint 15 is used to adapt to the valve core 23 to introduce the gas into the tire body 21 through the valve core 23. In the present invention, the solenoid valve 110 has an air intake module and a deflation module, wherein the air intake module is used for inflation, and the deflation module is used for deflation. The two work alternately to realize the inflation and deflation of the tire 2.

[0053] In the present invention, a central processing unit (not shown in the figure) is also provided on the PCB board 17, and a PLC control system is provided inside the central processing unit to facilitate signal connection of the above-mentioned electrical components;

[0054] In the present invention, a buzzer (not shown in the figure) is also provided inside the installation chamber, and the buzzer is used to give an alarm according to the setting of the program. At the same time, a sensor (not shown in the figure) is also provided near the solenoid valve 110 to detect the air pressure in the pipeline;

[0055] For the convenience of explanation, the working conditions of the tire pressure gun 1 are described in different situations:

[0056] 1. Standby mode

[0057] Step 1: After the tire pressure gun 1 is assembled, it is powered on. If the air inlet pressure and the air outlet pipe 14 are not connected, the device cannot detect any pressure and the solenoid valve 110 does not work. When the confirmation key is not pressed, the plus and minus keys and the unit conversion keys can be freely adjusted and set. If the confirmation key is pressed, the sensor cannot detect the pressure after the first solenoid valve 110 is opened for 0.2 seconds to 0.5 seconds. The sensor cannot detect the pressure again after the second opening for 0.5 seconds to 1 second. The sensor cannot detect the pressure again after the third opening for 1 second to 1.5 seconds. There is no pressure display after three times of operation, and the error prompt shows "ERR1". The normal interface is restored after 1 second.

[0058] In the second step, if the air source is connected and the confirmation key is not pressed, the unit conversion key and the plus and minus keys can be freely adjusted and set. If the confirmation key is pressed, the air outlet is not equipped with a normally closed air pipe (the air outlet pipe 14 and the second connector 15). The solenoid valve 110 is opened for 0.2 to 0.5 seconds for the first time, 3 to 5 seconds for the second time, and 5 to 8 seconds for the third time. There is no pressure display after working three times, and the error prompt displays "ERR1". The normal interface is restored after the error continues for 3 seconds.

[0059] 2. Inflatable state

[0060] When the tire pressure gun 1 is connected to the air intake pressure and the air pipe, the pressure in the normally closed air pipe connected to the tire 2 drops greatly, the sensor detects the actual pressure but the display screen 16 shields the pressure value and does not display it, and the display screen 16 displays 0.00BAR;

[0061] The solenoid valve 110 starts to work for 0.5 to 1 second, and a huge pressure increase occurs in the air pipe. The second inflation is performed for 3 to 5 seconds. If there is still no huge pressure increase in the normally closed air pipe, the display screen 16 displays the actual pressure in the tire 2 until it is consistent with the set pressure, then stops working and the buzzer alarm prompts that END and the actual pressure value flash back and forth. If the air pipe is not removed for 1 minute, the buzzer alarm is sounded again;

[0062] When the tire 2 is inflated, the pressure in the normally closed air pipe will change (will be lower than the set pressure) when the solenoid valve 110 is unplugged. The normally closed air pipe will experience a huge pressure increase, stop working, and shield the pressure value, display 0.00BAR, and automatically shut down after 30 seconds. After shutting down, the air pressure in the normally closed air pipe leaks for a long time, and it does not work when it is 0. To start it again, you need to press the confirmation key to work (return to the second step of the standby state);

[0063] When leakage occurs in the normally closed air pipe and the pressure is equal to or lower than 1BAR, the solenoid valve 110 is automatically opened and works for 0.2 seconds to 0.5 seconds. A huge pressure increase occurs in the normally closed air pipe, and the machine returns to the standby state. The actual pressure in the normally closed air pipe is not displayed, and the display screen 16 shows 0.00BAR. If there is no re-inflation after 30 seconds, the machine will automatically shut down. When the air pressure in the normally closed air pipe is 0 for a long time due to leakage, it does not need to work. To turn it on again, you need to press the confirmation key to work (return to the second step of the standby state).

[0064] 3. Deflation state

[0065] After the tire pressure gun 1 is connected, the pressure is adjusted and set by using the plus and minus keys. For example, if the set pressure is 2.2BAR, the sensor detects that the actual pressure of the tire 2 is 2.5BAR, the display screen 16 displays the actual pressure of the tire 2, and opens the solenoid valve 110 to start deflation until it is consistent with the set pressure value, then stops working and buzzers alarm, and the prompt display END and the actual pressure value flash back and forth. If the air tube is not removed for 1 minute, the buzzer alarm will be sounded again;

[0066] When the tire 2 is inflated, the pressure in the normally closed air pipe will change (will be lower than the set pressure) when the solenoid valve 110 works once, and the normally closed air pipe will experience a huge pressure increase, stop working, and shield the pressure value, display 0.00BAR, and automatically shut down after 30 seconds. After shutting down, if the air pressure in the normally closed air pipe leaks to 0 for a long time, it does not need to work. To start it again, you need to press the confirmation key to work (return to the second step of the standby state);

[0067] When leakage occurs in the normally closed air pipe and the pressure is equal to or lower than 1BAR, the solenoid valve 110 is automatically opened and works for 0.2 seconds to 0.5 seconds. A huge pressure increase occurs in the normally closed air pipe, and the machine returns to the standby state. The actual pressure in the normally closed air pipe is not displayed, and the display screen 16 shows 0.00BAR. If there is no re-inflation after 30 seconds, the machine will automatically shut down. When the air pressure in the normally closed air pipe is 0 for a long time due to leakage, it does not need to work. To turn it on again, you need to press the confirmation key to work (return to the second step of the standby state).

[0068] Embodiment 2:

[0069] When the tire pressure gun 1 is used to inflate a heavy-duty new energy vehicle, the inflation time is relatively long, and the tire pressure gun 1 will vibrate during the inflation process, so the operator needs to hold the gun in hand for operation, which easily causes fatigue and soreness in the user's hands. In addition, because the stop position of the tire 2 is relatively random, the valve core 23 will stay at any position, which makes it difficult to operate at some angles, affecting the inflation of the tire 2.

[0070] In order to solve the above problems, this embodiment provides an adjustment mechanism 3, which is integrated with the tire pressure gun 1 and can support the tire pressure gun 1. At the same time, the angle can be adjusted as needed to adapt to different inflation requirements. Specifically:

[0071] like Figure 3-Figure 5 As shown, a center ring 22 is provided at the center of the tire 2. The center ring 22 is a standard configuration of the tire 2 and is generally made of steel.

[0072] At the same time, a magnetic seat 4 is magnetically installed at the center circle 22, and the magnetic seat 4 has a seat body 41 and a magnetic attraction portion 42 installed corresponding to the center circle 22. At the same time, an adjustment button 43 is installed on the seat body 41. The adjustment button 43 is suitable for adsorbing the seat body 41 on the center circle 22 in a locked state, and when the adjustment button 43 is in a relaxed state, the seat body 41 can be separated from the center circle 22. The magnetic seat 4 is a common device. The specific structure and principle can be referred to relevant literature, and will not be repeated here;

[0075] Meanwhile, a screw rod 325 is threadedly mounted on the first clamping plate 321, and the screw rod 325 is bearing-mounted with the second clamping plate 324, and a rotating disk 326 is fixedly mounted on one end of the screw rod 325 away from the second clamping plate 324, so that the staff can control the distance between the first clamping plate 321 and the second clamping plate 324 by rotating the rotating disk 326;

[0076] A clamping portion 322 is fixedly installed at the bottom of the first clamping plate 321 and the second clamping plate 324. The two sets of clamping portions 322 are arranged in an arc shape at positions close to each other, so that when the first clamping plate 321 and the second clamping plate 324 are close to each other, they are held on the fixed shaft 31 to fix the clamping assembly 32.

[0077] Continue to refer Figure 7-Figure 9 The rotating assembly 33 includes an extension plate 345 fixedly mounted on the second clamping plate 324, and an arc-shaped rail 331 is fixedly mounted on one end of the extension plate 345 away from the second clamping plate 324.

It can be understood that the arc-shaped rack 332 can slide along the arc-shaped track, so as to slide to any position of the circumference;

[0078] At the same time, a bracket 36 is fixedly mounted on the arc-shaped rack 332, and the bracket 36 is used to mount the tire pressure gun 1, so that the tire pressure gun 1 can be located at any position of the circumference along with the sliding of the arc-shaped rack 332, so as to facilitate the connection of the valve core 23 at different angles, and due to the function of the bracket 36, the staff does not need to hold it manually, thereby reducing the work intensity of the staff;
