The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0032] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] Reference Figures 1 to 4 , the present application proposes a camping vehicle that stops suddenly after a collision, comprising a vehicle body 1, a battery compartment 2 and a driving device;

[0035] The driving device is mounted on the vehicle body 1, and the battery compartment 2 is detachably connected to the vehicle body 1; specifically, a bracket 11 is provided at the bottom of the vehicle body 1, and a fixing groove 28 with an opening facing upward is provided on the battery compartment 2, and a plurality of openings are provided on the side wall of the fixing groove 28, and a fixing pin is provided in the opening, and the fixing groove 28 is connected to the bracket 11 through the fixing pin. The groove width of the fixing groove 28 is adapted to the thickness of the bracket 11, and the bracket 11 can be just stuck in the fixing groove 28. Through a plurality of fixing pins that pass through the side wall of the fixing groove 28 and the bracket 11 in sequence, the battery compartment 2 can be firmly installed at the bottom of the vehicle body 1. Under the cover of the vehicle body 1, the battery compartment 2 will not be wetted by rain, reducing the risk of short circuit caused by the battery pack contacting water.

[0036] A main control board 21 is provided in the battery compartment 2, and a gyroscope 22 is fixedly provided on the main control board 21, and the gyroscope 22 is horizontally installed on the main control board 21. The gyroscope 22 can collect the angular velocity of the camper, and the gyroscope 22 is connected to the main control board 21 by signal, and the main control board 21 can make the drive device perform a preset braking operation. The gyroscope 22 is an angular velocity sensor, which can be a chip-shaped MEMS (micro-electromechanical gyroscope 22), fixed on the main control board 21, and monitors the angular velocity of the camper. When the camper collides with an obstacle or a user, the angular velocity of its movement will produce an instantaneous large change. When the gyroscope 22 detects that the angular velocity of the current camper is greater than a preset value, a signal is generated and the instantaneous change signal is transmitted to the main control board 21. The preset value varies according to the use status and size of the camper. For example, when the angular velocity exceeds 25rad / s, it can be determined that the camper has encountered a collision. At this time, the main control board 21 receives the signal transmitted by the gyroscope 22 and makes the drive device brake. Specifically, the driving device includes at least one fixed wheel 3 and at least one universal wheel 4. In this embodiment, two universal wheels 4 are arranged at the front end of the vehicle body 1, and two fixed wheels 3 are arranged at the rear end of the vehicle body 1. The camper in this embodiment is rear-wheel drive and braked. The universal wheels 4 at the front end of the vehicle body 1 can be rotated arbitrarily to facilitate the steering control of the camper. The fixed wheels 3 at the rear end of the vehicle body 1 are fixedly oriented to face forward to perform operations such as forward movement, backward movement or braking.

[0037] In this embodiment, first connectors 23 are provided on both sides of the battery compartment 2, and the first connectors 23 are electrically connected to the main control board 21. A hub motor (not shown in the figure) is provided in the directional wheel 3, and the main control board 21 is electrically connected to the hub motor through the first connector 23. A connecting wire 24 is provided between the connector and the hub motor, and one end of the connecting wire 24 is electrically connected to the connector, and the other end is electrically connected to the hub motor.

[0038] When the main control board 21 receives the signal, it controls the wheel hub motor to stop working and brake the camper through two symmetrically arranged first connectors 23. The specific implementation structure is similar to the prior art and will not be described here.

[0039] In this embodiment, the battery compartment 2 includes an upper shell 201 and a lower shell 202, the upper shell 201 covers the lower shell 202, and the fixing grooves 28 are arranged on the upper shell 201. The fixing grooves 28 are connected to each other to form a plurality of "T" shapes, and accordingly, the shape of the bracket 11 is adapted to the shape formed by the combination of the fixing grooves 28. Since the weight of the battery compartment 2 is borne by the bracket 11, a plurality of positioning pins are required between the bracket 11 and the fixing grooves 28 to achieve a stable connection.

[0040] The battery compartment 2 is provided with a accommodating groove 25 with a side opening, the accommodating groove 25 is located in the lower shell, a battery box 26 is provided in the accommodating groove 25, a battery pack 27 is provided in the battery box 26, and the battery pack 27 is electrically connected to the main control board 21. An electrical connector 261 connected to the main control board 21 is provided on the side wall of the battery box 26, and an electrical interface 271 is provided on the side wall of the battery pack 27. After the battery box 26 is stably installed, the electrical interface 271 is correspondingly connected to the electrical connector 261, and the battery pack 27 supplies power to the main control board 21.

[0041] In this embodiment, the battery compartment 2 is arranged between the two directional wheels 3. Since the directional wheels 3 are driving wheels, and the battery compartment 2 is arranged in the middle of the two directional wheels 3, the vibration of the camper during driving will have a certain impact on the operation of the gyroscope 22, and if the gyroscope 22 is installed at a position close to the universal wheel 4, when the camper is driving normally, the movement amplitude of the front end of the camper is large, which may cause misjudgment. The gyroscope 22 is installed at the rear end of the body 1 close to the center of gravity of the camper and close to the two directional wheels 3. When a collision occurs, the gyroscope 22 can monitor the change of the angular velocity of the camper more quickly and accurately, and respond quickly, so that the main control board 21 controls the directional wheels 3 to brake.

[0042] Furthermore, the camper also includes a control handle 5, and the battery compartment 2 is further provided with a second connector 29, and the control handle 5 is electrically connected to the main control board 21 via the second connector 29. When the user is towing the camper, the user can also operate the control handle 5 to make the camper perform acceleration, deceleration or braking operations.
