[0033] With the development of social economy, the sales market is constantly expanding, and the sales forms are becoming more and more diversified. More and more cities are beginning to use sales trucks. Sales trucks, also known as vending vehicles, refer to van-type special-purpose vehicles equipped with sales windows, shelves, containers and other facilities for mobile sales. They can be used for mobile sales in leisure squares, campuses, celebrations, tourist attractions, township markets and other places. They also have the functions of corporate image promotion, distribution, on-site sales, and promotional activities. When using sales trucks for sales, the sales location can be adjusted according to the number of consumers at different times and in different regions. It has good liquidity, high flexibility and strong adaptability. At the same time, sales trucks integrate sales and transportation, which greatly reduces the cost of product transportation. Sales trucks have many advantages in one, and their market potential is huge.

[0034] The sales window of the sales truck is located on the side of the car body. After the sales truck stops, the side door can be opened as a sales booth. The side door and the car body can be flipped and connected, but the side door panel is generally bulky and the side door panel is flipped up to a high height, which makes it inconvenient for users to manually open and close the side door. Therefore, it is necessary to introduce an automatic opening and closing side door mechanism for the sales truck. The automatic opening and closing side door mechanism uses the first control unit as the core control unit and is equipped with accessories such as the side door electronic switch and electric push rod, which can automatically control the opening and closing of the side door according to user operations. The working principle of the automatic opening and closing side door mechanism is specifically as follows: the first control unit is energized and enabled when the ignition switch is in the ACC gear or the LOCK gear (the vehicle is generally in a parked state at this time), and is de-energized when the ignition switch is in the ON gear or the START gear (the vehicle generally starts to enter or has entered a driving state at this time). In other words, the automatic opening and closing side door mechanism is only energized and enabled when the ignition switch is in the ACC gear or the LOCK gear; after the first control unit 1 is energized and enabled, the user automatically controls the extension and retraction of the electric push rod by triggering the side door electronic switch, thereby driving the opening and closing of the side door. The operation is convenient and flexible, making people's work and life more comfortable and safer.

[0035] Among them, the ignition switch is the switch of the ignition system of the sales truck, which can freely open or close the main circuit of the ignition coil. The four gears of the ignition switch are: ON gear, START gear, ACC gear and LOCK gear. The description of each gear is as follows:

[0036] 1. ON gear

[0037] The ON position is the position for the whole vehicle to be powered on. When the key is turned to this position, the whole vehicle circuit is connected, and the vehicle system will make necessary preparations and self-checks for starting the engine. The key will remain in this position when the vehicle is driving normally. When the key is in the ON position during normal driving, all the circuits of the whole vehicle are in working condition.

[0038] 2. START gear

[0039] START gear is the vehicle start gear, which is also the engine start gear. When the key is turned to this gear position, the starter circuit is connected, which will drive the engine to run and start. After starting, when the key is released, it will automatically return to the ON gear.

[0040] 3. ACC gear

[0041] ACC gear is the accessory power-on gear. When the key is turned to this gear position, the accessory circuits (such as air conditioning, radio, etc.) will be turned on.

[0042] 4. LOCK block

[0043] The LOCK position is the position for inserting and removing the key. At this time, except for the anti-theft system and some low-voltage devices such as the small lights in the car, the circuit of the vehicle is completely closed and the steering wheel is locked. After the car is locked, the key will enter the LOCK position.

[0044] However, during the use of the sales truck, it is inevitable that the side door will not be fully closed at any position of the ignition switch, for example:

[0045] 1. The user usually opens and closes the side door only after the vehicle is parked. When the user uses the automatic side door opening and closing mechanism to close the side door, it is inevitable that the side door will not be fully closed due to abnormalities in the automatic side door opening and closing mechanism itself or someone accidentally touches the side door electronic switch. At this time, the side door panel is prone to lose control and flip down quickly, and the surrounding personnel may not notice this situation in time, which can easily cause injuries to the surrounding personnel and damage to the goods.

[0046] 2. After the user uses the automatic opening and closing side door mechanism to close the side door and drives the sales truck on the road, the side door may pop out accidentally during the journey, that is, the side door is not closed properly, and the surrounding people may not notice this situation in time, which may easily cause injuries to the surrounding people and damage to the goods.

[0047] In order to realize timely alarm when the side door is not fully closed, the embodiment of the utility model discloses a side door control system for a sales truck, such as Figure 2 As shown, it includes: an automatic opening and closing side door mechanism; the automatic opening and closing side door mechanism uses the first control unit 1 as the core control unit, and is equipped with accessories such as a side door electronic switch and an electric push rod ( Figure 2 (not shown), can automatically control the opening and closing of the side door according to user operation;

[0048] The sales truck side door control system further includes: a second control unit 2, a first alarm 3, a second alarm 4, a vehicle power supply 7 and a side door status sensor 5;

[0049] The side door status sensor 5 is used to detect whether the side door of the sales truck is fully closed, and the output end of the side door status sensor 5 is connected to the input end of the first control unit 1 and the input end of the second control unit 2;

[0050] The output end of the first control unit 1 is connected to the first alarm 3;

[0051] The output end of the second control unit 2 is connected to the second alarm 4;

[0052] The power supply end of the first control unit 1 is connected to the ignition switch 6 of the vending truck, and is powered on and enabled only when the ignition switch 6 is in the ACC gear or the LOCK gear;

[0053] The power supply end of the second control unit 2 is connected to the vehicle power supply 7;

[0054] The enabling terminal of the second control unit 2 is connected to the power supply terminal of the first control unit 1 , and the second control unit 2 is enabled only when the first control unit 1 loses power.

[0055] The working principle of the embodiment of the utility model is described in detail below:

[0056] Based on the gear characteristics of the ignition switch described above, it can be known that the first control unit 1 is powered on and enabled when the ignition switch 6 is in the ACC gear or the LOCK gear (the vehicle is generally in a parked state at this time), and is powered off when the ignition switch 6 is in the ON gear or the START gear (the vehicle generally begins to enter or has entered a driving state at this time). The second control unit 2 is continuously powered by the vehicle power supply 7, and the first control unit 1 is triggered to enable the second control unit 2 after the power is lost, so the second control unit 2 does not work when the ignition switch 6 is in the ACC gear or the LOCK gear, and starts to work when the ignition switch 6 is in the ON gear or the START gear, that is, the second control unit 2 is enabled when the first control unit 1 is powered off.

[0057] The side door control system of the sales truck includes two alarm systems: the first alarm system uses the first control unit 1 as the core control unit (the first control unit 1 also serves as the core control unit of the automatic side door opening and closing mechanism and the first alarm system), and is mainly composed of the first control unit 1, the side door state sensor 5 and the first alarm 3; the second alarm system uses the second control unit 2 as the core control unit, and is mainly composed of the second control unit 2, the side door state sensor 5, the vehicle power supply 7 and the second alarm 4. It can be said that the second alarm system is activated when the first alarm system loses power.

[0058] When the ignition switch 6 is in the ACC gear or the LOCK gear, the first control unit 1 is powered on and enabled. At this time, the first alarm system and the automatic opening and closing mechanism of the side door are in working state. Specifically: after the first control unit 1 is powered on and enabled, it automatically controls the extension and retraction of the electric push rod according to the user operation, thereby driving the opening and closing of the side door; when the automatic closing operation of the side door is completed, if the first control unit 1 determines that the side door is not fully closed according to the output signal of the side door status sensor 5 (this is mainly for the aforementioned situation 1. During the automatic closing process of the side door, if the side door is not detected to be fully closed within the time limit, it is determined that the side door is not fully closed), then the first alarm 3 is triggered to alarm, so as to warn the user to close or repair the side door; the first control unit 1 does not respond to the output signal of the side door status sensor 5 during the normal opening process of the side door.

[0059] When the ignition switch 6 is in the ON position or the START position, the first control unit 1 loses power, the first alarm system and the automatic opening and closing side door mechanism stop working, and the second control unit 2 is enabled, so the second alarm system starts working. Specifically: when the side door status sensor 5 determines that the side door is not closed in place according to the output signal of the side door status sensor 5 (this is mainly for the aforementioned situation 2), the second alarm 4 is triggered to alarm, so as to warn the user to stop the car in time and close or repair the side door.

[0060] In summary, the embodiment of the utility model utilizes two sets of alarm systems to alternately detect and warn that the side door is not fully closed. When the ignition switch is in the ACC gear or the LOCK gear, the first set of alarm systems and the automatic side door opening and closing mechanism are powered on and activated. When the automatic side door opening and closing mechanism completes the side door closing operation, the first set of alarm signals will sound an alarm if it detects that the side door is not fully closed; the second set of alarm signals will be activated after the first set of alarm systems loses power, and will sound an alarm once it detects that the side door is not fully closed. Therefore, no matter what gear the ignition switch is in, the embodiment of the utility model can realize the alarm function for the side door not fully closed, greatly reducing the safety risk of the vehicle. The embodiment of the utility model has a simple structure, low production cost, and is easy to promote and apply.

[0061] In addition, in order to realize timely alarm after the side door is abnormally closed, the embodiment of the utility model discloses another side door control system of a sales truck, such as Figure 3 As shown, it includes: an automatic opening and closing side door mechanism; the automatic opening and closing side door mechanism uses the first control unit 1 as the core control unit, and is equipped with accessories such as a side door electronic switch and an electric push rod ( Figure 3 (not shown), can automatically control the opening and closing of the side door according to user operation;

[0062] The sales truck side door control system also includes: a second control unit 2, a first alarm 3, a second alarm 4, a controllable switch K1, a vehicle power supply 7 and a side door status sensor 5;

[0063] The side door status sensor 5 is used to detect whether the side door of the sales truck is fully closed, and the output end of the side door status sensor 5 is connected to the input end of the first control unit 1 and the input end of the second control unit 2;

[0064] The output end of the first control unit 1 is connected to the first alarm 3;

[0065] The output end of the second control unit 2 is connected to the second alarm 4;

[0066] The power supply end of the first control unit 1 is connected to the ignition switch 6 of the vending truck, and is powered on and enabled only when the ignition switch 6 is in the ACC gear or the LOCK gear;

[0067] The power supply end of the second control unit 2 is connected to the vehicle power supply 7 via the controllable switch K1; the control end of the controllable switch K1 is connected to the power supply end of the first control unit 1, and the controllable switch K1 is closed only when the first control unit 1 loses power.

[0068] Compared to Figure 2 , Figure 3The scheme shown introduces a controllable switch K1, and disconnects the control of the power supply terminal of the first control unit 1 on the enable terminal of the second control unit 2. The first control unit 1 is powered on and enabled when the ignition switch 6 is in the ACC gear or the LOCK gear, and loses power when the ignition switch 6 is in the ON gear or the START gear. After the first control unit 1 loses power, the controllable switch K1 is triggered to close, and after the controllable switch K1 is closed, the second control unit 2 can be powered on and enabled.

[0069] Next, Figure 3 The working principle of the scheme shown is described in detail:

[0070] Figure 3 The side door control system of the sales truck shown in the figure includes two alarm systems: the first alarm system uses the first control unit 1 as the core control unit (the first control unit 1 also serves as the core control unit of the automatic side door opening and closing mechanism and the first alarm system), and is mainly composed of the first control unit 1, the side door state sensor 5 and the first alarm 3; the second alarm system uses the second control unit 2 as the core control unit, and is mainly composed of the second control unit 2, the side door state sensor 5, the controllable switch K1, the vehicle power supply 7 and the second alarm 4. It can be said that the second alarm system is powered on and activated when the first alarm system loses power.

[0071] When the ignition switch 6 is in the ACC gear or the LOCK gear, the first control unit 1 is powered on and enabled. At this time, the first alarm system and the automatic opening and closing mechanism of the side door are in working condition. Specifically: after the first control unit 1 is powered on and enabled, it automatically controls the extension and retraction of the electric push rod according to the user operation, thereby driving the opening and closing of the side door; when the first control unit 1 completes the automatic closing operation of the side door, if it is determined according to the output signal of the side door status sensor 5 that the side door is not fully closed (this is mainly for the aforementioned situation 1), the first alarm 3 is triggered to warn the user to close or repair the side door; during the normal opening process of the side door, the first control unit 1 does not respond to the output signal of the side door status sensor 5.

[0072] When the ignition switch 6 is in the ON position or the START position, the first control unit 1 loses power, the first alarm system and the automatic opening and closing side door mechanism stop working, and the second control unit 2 is powered on and enabled, so the second alarm system starts working. Specifically: when the side door status sensor 5 determines that the side door is not closed in place according to the output signal of the side door status sensor 5 (this is mainly for the aforementioned situation 2), the second alarm 4 is triggered to alarm, so as to warn the user to stop the car in time and close or repair the side door.
