Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle control, and in particular relates to a vehicle leveling auxiliary device. Background Art

[0002] With the development of automation technology, automatic leveling technology is increasingly being used in production and daily life, such as electronic equipment platforms and recreational vehicles. Because these vehicles carry a large number of equipment and require ample space for movement, the center of gravity can shift during use due to user activity and the placement of various equipment. Relying solely on tire support cannot ensure levelness or ideal stability, seriously affecting performance. Furthermore, as a mobile home, RVs must be kept level when parked to ensure comfort and safety.

[0003] During the vehicle leveling process, leveling auxiliary tools are often used to ensure that the RV is in a horizontal state. Existing leveling auxiliary tools such as Figure 1 As shown, it includes two horizontal bubblers, which are arranged perpendicular to each other. The leveling auxiliary device is horizontally installed on the inner wall of the RV compartment. By observing the position of the bubbles in the horizontal bubblers on the leveling auxiliary device, it is determined whether the compartment is in a horizontal state. When the bubbles in the horizontal bubbler are offset left or right, it means that the compartment is tilted to the left or right. When the bubbles in the vertical bubbler are offset front or back, it means that the compartment is tilted forward or backward. When the bubbles in the horizontal and vertical bubblers are both in the middle position, it means that the compartment remains horizontal in all directions. However, the disadvantages of the leveling auxiliary device are: 1) the accuracy of assisting the leveling of the RV is poor by only observing the bubble position with the naked eye; 2) when the RV leveling device is used for leveling, the user has to get back on the vehicle to check the bubble position every time he gets off the vehicle to level it. The leveling process is cumbersome and time-consuming. This is the shortcoming of the existing technology. Summary of the Invention

[0004] The purpose of the utility model is to provide a vehicle leveling assistance device to solve the problems existing in the prior art, in which the existing leveling assistance device only assists in leveling the RV by observing the bubble position with the naked eye, which has poor accuracy. The user has to get back on the vehicle to check the bubble position every time he gets off the vehicle to level it, and the leveling process is cumbersome and time-consuming.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A vehicle leveling auxiliary device includes a posture sensor, an MCU, a Bluetooth transceiver, a mobile terminal, a power management chip, and a battery pack, wherein the posture sensor, the MCU, and the Bluetooth transceiver are all connected to the battery pack via the power management chip;

[0007] The attitude sensor is vertically installed inside the vehicle to be leveled. The output end of the attitude sensor is connected to the first input end of the MCU. The MCU is connected to the mobile terminal through a Bluetooth transceiver.

[0008] A further improvement of this technical solution is that the attitude sensor adopts an attitude sensor of model LIS3DHTR.

[0009] A further improvement of the technical solution is that the battery pack includes two AA batteries.

[0010] A further improvement of the technical solution is that it also includes a clock chip, the power supply end of the clock chip is connected to the battery pack through the power management chip, and the clock chip is communicatively connected to the MCU.

[0011] A further improvement of the technical solution is that it also includes a temperature and humidity sensor, the power supply end of the temperature and humidity sensor is connected to the battery pack through the power management chip, and the temperature and humidity sensor is communicatively connected to the MCU.

[0012] A further improvement of the technical solution is that it also includes a shell, and the posture sensor, MCU, Bluetooth transceiver, power management chip, battery pack, clock chip and temperature and humidity sensor are all arranged in the shell.

[0013] The beneficial effect of the present invention is that the present invention detects the inclination of the vehicle through the attitude sensor, and sends it to the mobile terminal in the user's hand through the MCU and the Bluetooth transceiver in sequence, so that the user can directly use the vehicle leveling auxiliary device to level the vehicle outside the vehicle without having to get on and off the vehicle to check many times, thus saving vehicle leveling time, and the accuracy of the data collected by the attitude sensor is definitely higher than the accuracy observed by the user's naked eye, thereby improving the leveling accuracy.

[0019] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts should fall within the scope of protection of the present invention.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0021] The key terms appearing in this utility model are explained below.

[0022] MCU, Microcontroller Unit, also known as Single Chip Microcomputer or SCM, is a chip-level computer that reduces the frequency and specifications of the Central Processing Unit (CPU) and integrates memory, timers, USB, A / D converters and other peripheral interfaces, and even display driver circuits on a single chip to form a chip-level computer that can provide different combination controls for different applications.

[0023] like Figure 2 As shown, the utility model provides a vehicle leveling auxiliary device, including a posture sensor, an MCU, a Bluetooth transceiver, a mobile terminal, a power management chip and a battery pack. The posture sensor, the MCU and the Bluetooth transceiver are all connected to the battery pack through the power management chip; the posture sensor is vertically installed inside the vehicle to be leveled, the output end of the posture sensor is connected to the first input end of the MCU, and the MCU is communicatively connected to the mobile terminal through the Bluetooth transceiver.

[0024] Specifically, the attitude sensor uses a posture sensor model LIS3DHTR, and the battery pack includes two AA batteries. The battery voltage of the battery pack is about 3.2V when fully charged. During the long-term operation of the device, as the battery power is consumed, the battery voltage will gradually drop to a termination voltage of 1.8V. The battery voltage is input to the power management chip, and the power management chip fixedly outputs a stable voltage of 3.3V to ensure the normal operation of the device.

[0025] In addition, the vehicle leveling auxiliary device also includes a clock chip, a temperature and humidity sensor and a shell. The power supply end of the clock chip is connected to the battery pack through the power management chip, and the clock chip is communicated with the MCU. The clock chip is used as the signal source for time and date; the power supply end of the temperature and humidity sensor is connected to the battery pack through the power management chip, and the temperature and humidity sensor is communicated with the MCU; the posture sensor, MCU, Bluetooth transceiver, power management chip, battery pack, clock chip and temperature and humidity sensor are all arranged in the shell.

[0026] The vehicle leveling assistance device also includes a button, one end of which is connected to the power management chip, and the other end of the button is connected to the MCU. When the MCU detects that the button is pressed, the MCU will exit the low-power mode for 30 seconds. During this period, if the Bluetooth module of the mobile terminal is paired, the vehicle leveling assistance device will enter the RV leveling horizontal angle measurement mode; if the Bluetooth module of the mobile terminal is not connected within 30 seconds, the vehicle leveling assistance device will re-enter the low-power mode to achieve the purpose of saving power.

[0027] The working principle of the vehicle leveling auxiliary device is as follows: press the button to establish a communication connection between the MCU and the mobile terminal through the Bluetooth transceiver, the attitude sensor detects the horizontal state of the RV, and sends the obtained front and rear tilt angle information and left and right tilt angle information of the RV to the MCU, and the MCU sends the received tilt angle information to the mobile terminal through the Bluetooth transceiver. The user levels the vehicle outside the RV according to the information from the handheld mobile terminal, avoiding the tedious step of entering the car to check whether the bubble in the level bubble is in the middle position every time the user levels the RV, thereby improving the leveling efficiency and accuracy.

[0028] The above disclosure is only a preferred embodiment of the present invention, but the present invention is not limited thereto. Any non-creative changes that can be thought of by technicians in this field, as well as several improvements and modifications made without departing from the principles of the present invention, should fall within the scope of protection of the present invention.
