Therefore, they should not be construed as limitations on the embodiments of this disclosure.

[0051] The present disclosure will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0052] This embodiment provides a control method for a lifting device, which includes a multi-layer lifting device and a multi-layer lifting module;

[0053] The control method includes:

[0054] Each multi-layer lifting module is connected to a multi-layer lifting device. Each layer lifting module independently controls the lifting of each layer lifting device. The lifting status of each layer lifting device is determined by the position status of the other layer lifting devices, or the lifting status of each layer lifting device is the same.

[0055] In this embodiment, since the multi-layer control module is connected to the multi-layer lifting device respectively, each layer of the lifting device can be precisely operated and adjusted, realizing independent movement between the multi-layer lifting devices and improving the flexibility of control.

[0056] Specifically, the multi-layer lifting device can be controlled by the lifting module, so that any one of the layers needs to rise or fall on the premise that the other layers are in the lowest or highest position to meet the user's needs.

[0057] The lifting device provided in the embodiment can be applied to a multi-layer lifting tent, warehouse or logistics and other scenarios for vertical movement or vertical transportation. Taking a two-layer lifting tent as an example, as shown in FIG. 2, the number of the lifting device is two, which are a first layer lifting device 1 and a second layer lifting device 2, and the first layer lifting device 1 is below the second layer lifting device 2. Both the first layer lifting device 1 and the second layer lifting device 2 can adopt a lifting platform, and a tent is arranged between adjacent two lifting platforms, which is convenient to use.

[0058] Further, the second layer lifting device 2 is in the lowest position when the first layer lifting device 1 rises, and the second layer lifting device 2 is in the lowest position when the first layer lifting device 1 falls.

[0059] Specifically, when the one-layer lifting module needs to execute the rising instruction of the first layer lifting device 1, it is first needed to judge whether the second layer lifting device 2 has fallen to the lowest position. If the second layer lifting device 2 has fallen to the lowest position at this time, the one-layer lifting module executes the rising instruction of the first layer lifting device 1, thereby driving the first layer lifting device 1 to rise. If the second layer lifting device 2 has not fallen to the lowest position at this time, the two-layer lifting module needs to execute the falling instruction of the second layer lifting device 2 first, and then the one-layer lifting module executes the rising instruction of the first layer lifting device 1, thereby driving the first layer lifting device 1 to rise. In other embodiments, the state relationship between the rising of the first layer lifting device 1 and the second layer lifting device 2 can also be adjusted to meet the actual needs.

[0060] Similarly, when the one-layer lifting module needs to execute the falling instruction of the first layer lifting device 1, it is first needed to judge whether the second layer lifting device 2 has fallen to the lowest position. If the second layer lifting device 2 has fallen to the lowest position at this time, the one-layer lifting module executes the falling instruction of the first layer lifting device 1, thereby driving the first layer lifting device 1 to fall. If the second layer lifting device 2 has not fallen to the lowest position at this time, the two-layer lifting module needs to execute the falling instruction of the second layer lifting device 2 first, and then the one-layer lifting module executes the falling instruction of the first layer lifting device 1, thereby driving the first layer lifting device 1 to fall. In other embodiments, the state relationship between the falling of the first layer lifting device 1 and the second layer lifting device 2 can also be adjusted to meet the actual needs.

[0061] Further, the second layer lifting device 2 is in the lowest position when the first layer lifting device 1 rises, and the second layer lifting device 2 is in the lowest position when the first layer lifting device 1 falls.

[0062] Specifically, when the two-layer lifting module needs to execute the lifting instruction of the second layer lifting device 2, it is first needed to judge whether the first layer lifting device 1 has been lifted to the highest position. If the first layer lifting device 1 has been lifted to the highest position at this time, the two-layer lifting module executes the lifting instruction of the second layer lifting device 2, thereby driving the second layer lifting device 2 to lift. If the first layer lifting device 1 has not been lifted to the highest position at this time, the one-layer lifting module needs to execute the lifting instruction of the first layer lifting device 1 first, and then the two-layer lifting module executes the lifting instruction of the second layer lifting device 2, thereby driving the second layer lifting device 2 to lift. In other embodiments, the state relationship between the lifting of the second layer lifting device 2 and the first layer lifting device 1 can also be adjusted to meet the actual needs.

[0063] Similarly, when the two-layer lifting module needs to execute the lowering instruction of the second layer lifting device 2, it is first needed to judge whether the first layer lifting device 1 has been lifted to the highest position. If the first layer lifting device 1 has been lifted to the highest position at this time, the two-layer lifting module executes the lowering instruction of the second layer lifting device 2, thereby driving the second layer lifting device 2 to lower. If the first layer lifting device 1 has not been lifted to the highest position at this time, the one-layer lifting module needs to execute the lifting instruction of the first layer lifting device 1 first, and then the two-layer lifting module executes the lowering instruction of the second layer lifting device 2, thereby driving the second layer lifting device 2 to lower. In other embodiments, the state relationship between the lowering of the second layer lifting device 2 and the first layer lifting device 1 can also be adjusted to meet the actual needs.

[0064] Further, as shown in FIGS. 1-3, the main control system 3, the slave control system 4 and a plurality of peripheral devices 5 are further included, the main control system 3 and the slave control system 4 are arranged on the lifting device, each layer of the lifting device is provided with a plurality of peripheral devices 5, the main control system 3 is provided with a main controller 31, the main controller 31 is connected with the lifting module and the plurality of peripheral devices 5 respectively, and is used for controlling the lifting module and the plurality of peripheral devices 5, and a communication connection is established between the main control system 3 and the slave control system 4. The main control system 3 and the slave control system 4 of the embodiment can flexibly adjust the working state of the lifting device and the peripheral device 5 according to needs, and adapt to different application scenarios and needs.

[0065] Further, the lifting module of the embodiment is an electric push rod, but is not limited thereto, the electric push rod is provided with a speed measurement module, the speed measurement module is connected with the main controller 31, and is used for transmitting the lifting speed information of the lifting device to the main controller 31.

[0066] Specifically, two electric push rods are arranged on each layer of the lifting device in the embodiment, but the embodiment is not limited thereto, so that the lifting process of the lifting device is more stable. Meanwhile, the speed measuring module can monitor the lifting speed of the electric push rod in real time, so as to ensure that the lifting device works at a predetermined speed. By monitoring the lifting speed, the main controller 31 can discover abnormal conditions such as overspeed or unstable speed in time, so as to take corresponding protection measures to avoid safety accidents and improve the safety performance of the entire lifting device. The main controller 31 can optimize the control strategy of the electric push rod according to the data provided by the speed measuring module. For example, when it is detected that the lifting speed is too slow, the output power of the motor can be adjusted to increase the speed; when the speed is too fast, the output power can be reduced to avoid impact and wear.

[0067] Further, the slave control system 4 comprises a power module 40, a slave controller 41 and a Bluetooth module 42, the power module 40 and the Bluetooth module 42 are connected with the slave controller 41 respectively, the Bluetooth module 42 is connected with the main controller 31 to establish a communication connection, and the power module 40 comprises: a power management module 400, which is used for switching the battery power supply mode of the power module 40 and the external power supply mode when the power module 40 is connected with an external charger, and controlling the opening and closing of the external power supply mode; a battery charging and discharging management module 401, which is used for controlling the charging and discharging of the battery of the power module 40; and a power display module 402, which is used for displaying the battery information, power supply mode information and state information of the peripheral device 5 of the power module 40.

[0068] For various peripheral devices 5 on the lifting device, the battery power supply mode of the power module 40 of the slave control system 4 is used for power supply or the external power supply mode of the power module 40 is used for power supply, which is flexible. Specifically, when the external charger is connected with the power management module 400 of the power module 40, the slave controller 41 detects the external power input, at this time, the slave controller 41 can select the battery power supply mode or the external power supply mode according to the battery state of the power module 40, and transmit the electric energy to the main controller 31, so that the main controller 31 distributes the electric energy to various peripheral devices 5. In addition, a switch key is arranged on the power module 40, which is electrically connected with the slave controller 41 and is used for opening or closing the power supply.

[0069] Further, the embodiment also provides a buzzer 43, which is electrically connected with the slave controller 41, and when the power module 40 is abnormal, the slave controller 41 controls the buzzer 43 to alarm in combination with the current state of the buzzer 43 and the control information received from the main controller 31. The battery capacity, charging and discharging indication, current power supply mode and state information of each peripheral device 5 are displayed on the power display module 402, which is convenient to use.

[0070] Further, as shown in FIG. 2, the peripheral devices 5 of the present embodiment include a USB interface, a loudspeaker, an LED light strip, a side light, and an anti-pinch module, but are not limited thereto, and the user can select and set the peripheral devices according to actual needs.

[0071] Since the first layer lifting device 1 needs to be arranged on an external device such as a car trunk, the first layer lifting device 1 of the present embodiment does not have a USB interface, but is not limited thereto. In addition to the first layer lifting device 1, other layers of lifting devices can have a USB interface. The present embodiment takes two layers of lifting devices as an example, the first layer lifting device 1 does not have a USB interface, and the second layer lifting device 2 has a USB interface, and the main controller 31 controls whether to supply power to the USB interface according to the position state of each layer of lifting devices. Specifically, when the second layer lifting device 2 rises to the highest position, the main controller 31 supplies power to the USB interface, and when the second layer lifting device 2 drops to the lowest position, the main controller 31 stops supplying power to the USB interface. At the same time, when the main controller 31 detects that the current of the USB interface is less than a threshold value within a certain time, it sends a control signal to the slave controller 41, and the slave controller 41 controls the power supply of the USB interface according to the current state of the USB interface and other states (such as the lifting state of the lifting device, the on-off state of the LED light strip or the side light, etc.).

[0072] The side light of the present embodiment is detachably arranged on the lifting device, and the side light is electrically connected with the main controller 31, and the main controller 31 cooperates with the slave controller 41 to supply power to the side light and control the on-off state of the side light. At the same time, taking two layers of lifting devices as an example, the main controller 31 cooperates with the slave controller 41 to make the side light also automatically turn on or off according to the lifting state of the two layers of lifting devices, such as automatically turning on when the lifting device rises to the highest position. Of course, the number of side lights can be adjusted, and the side lights can be used on each layer of lifting devices.

[0073] The LED light strip is provided on each layer of the lifting device, and the light-off state of the LED light strip is controlled by the main controller 31 in cooperation with the slave controller 41. Specifically, when each layer of the lifting device rises to the highest position, the LED light strip is automatically turned on. For the upper layer of the lifting device, a passage entrance can be provided on the lifting device, and a flap for covering the passage entrance is provided at the passage entrance, so that when the flap is opened, the lower layer of the lifting device can enter the upper layer of the lifting device through the passage entrance. In addition, a ladder can be provided on the lower layer of the lifting device for users to enter the upper space from the passage entrance. In the embodiment, the USB interface and the LED light strip can be controlled in linkage with the flap by the main controller 31. That is, when the upper layer of the lifting device rises to the highest position and the flap is opened, the USB interface is powered or the LED light strip is automatically turned on. The LED light strip of the embodiment has three brightness levels, but is not limited thereto. Specifically, the light-off or brightness level of the LED light strip can be controlled by the position state of the lifting device, the battery level of the power module 40, the remote control module 6 or the anti-pinch detection of the anti-pinch module, and the control mode of the auxiliary light is the same as that of the LED light strip, which will not be described in detail. In addition, the auxiliary light can also be controlled by the control switch.

[0074] In addition, the use state of the LED light strip and the auxiliary light can also be linked with the power module 40. Specifically, when the main controller 31 detects that the entire lifting device has not been operated for a certain period of time, the USB interface has not been used for charging, or the LED light strip and the auxiliary light are in an off state, etc., a signal will be sent to the slave controller 41, and the power supply to the entire lifting device will be turned off. The detection time threshold of the embodiment is ten minutes, but is not limited thereto, which can avoid waste of power and improve power utilization effect.

[0075] The anti-pinch module is provided on each layer of the lifting device. Specifically, when the anti-pinch module is triggered, an anti-pinch signal is transmitted to the main controller 31, the main controller 31 stops the corresponding lifting device from descending, and the lifting device is raised by a certain distance, thereby playing an anti-pinch role and effectively ensuring the safety of users.

[0076] For the anti-pinch detection of the anti-pinch module, physical detection or software detection can be used. When using physical detection, the anti-pinch module can use anti-pinch rubber strips, but is not limited to this. The anti-pinch rubber strips are placed on the frame used to fix the bottom lifting device, or on the top of the lifting device. When the anti-pinch rubber strip is detected to be activated during the descent of the lifting device, either the first-layer lifting device 1 or the second-layer lifting device 2 stops descending and rises a certain distance. When using software detection, as shown in Figure 4, taking a two-layer lifting device as an example, since the current of the electric actuator controlling the descent of the lifting device gradually decreases during the descent, when the second-layer lifting device 2 descends, if the current is not empty, the current value is read. If the current current value is greater than the sum of the current judgment value and the safety value at the previous moment, the lifting device stops descending and rises a certain distance. Conversely, if the current current value is less than the sum of the current judgment value and the safety value at the previous moment, the current current value is used as the current judgment value for the next moment.

[0077] Furthermore, the main controller 31 in this embodiment can also detect the opening and closing status of the flap of the upper lifting device and the locking and unlocking status of the ladder between the lifting devices. When the main controller 31 detects that the flap of the upper lifting device is open, or when the main controller 31 detects that the ladder between the lifting devices is locked, the main controller 31 can control the lifting device to maintain its current position height while also controlling the lifting device to rise and prohibiting the lifting device from descending, which helps to ensure the safety of use.

[0078] In this embodiment, a speaker is installed on each floor of the lifting device. The main controller 31 can control the speaker to play music or make various sounds such as voice broadcasts.

[0079] This embodiment also includes a remote control module 6, which is connected to both the main control system 3 and the slave control system 4, and is used to remotely control several peripheral devices 5. The remote control module 6 in this embodiment includes a wireless remote controller, a mini-program, and an app. The wireless remote controller establishes a connection with the main controller 31. For the wireless remote controller, the main controller 31 controls the raising and lowering of the lifting device, the volume of music played by the speaker, track switching, the on / off state of the speaker, the on / off state of the auxiliary lights and LED strips, or actively disconnects from other peripheral mobile devices, etc., based on the button information. The mini-program and app establish a connection with the Bluetooth module 42. For the mini-program or app, a communication connection can be established with the slave controller 41 through the Bluetooth module 42. Its control functions for the peripheral devices 5 are the same as those of the wireless remote controller, which will not be elaborated further. Furthermore, when the speaker is playing music, the mini-program or app can work with the Bluetooth module 42 to select whether to play audio information from the SD card, offering flexibility.

[0080] It should be further explained that, for the auxiliary lights on the lifting device, taking a two-layer lifting device as an example, when the lifting device rises to the highest position, the auxiliary lights inside the lifting device will automatically turn on. For the auxiliary lights of the second-layer lifting device 2, the auxiliary lights will only turn on when the flip panel is opened. When the lifting device is not at the lowest position, the lighting status of the auxiliary lights can be cyclically adjusted through the remote control module 6. The lighting status of the auxiliary lights includes floodlight level 1, floodlight level 2, spotlight, and off state. When the lifting device descends to the lowest position, the auxiliary lights will automatically turn off.

[0081] In this embodiment, when the lifting device is controlled by the remote control module 6, only one up button and one down button need to be set, and the main controller 31 automatically controls the lifting device.

[0082] Taking a two-layer lifting device as an example, as shown in Figure 5, when the up button is pressed, if the first-layer lifting device 1 has already risen to its highest position, the main controller 31 executes the up command for the second-layer lifting device 2, thereby driving the second-layer lifting device 2 to rise through the two-layer lifting module. If the first-layer lifting device 1 is not at its highest position and the second-layer lifting device 2 has already descended to its lowest position, the main controller 31 executes the up command for the first-layer lifting device 1, thereby driving the first-layer lifting device 1 to rise through the one-layer lifting module. If the first-layer lifting device 1 is not at its highest position and the second-layer lifting device 2 is not at its lowest position, the main controller 31 needs to first execute the down command for the second-layer lifting device 2, and then execute the up command for the first-layer lifting device 1, thereby driving the first-layer lifting device 1 to rise.

[0083] Taking a two-level lifting device as an example, as shown in Figure 6, when the descent button is pressed for the first time, if the second-level lifting device 2 is at its lowest position and the first-level lifting device 1 is not at its lowest position, a safety warning will be broadcast, such as checking whether there are people inside the lifting device's flaps, ladders, or tents, and whether anyone is approaching. When the descent button is pressed a second time, the main controller 31 executes the descent command for the first-level lifting device 1, thereby lowering it to a position 20 centimeters from its lowest position via the first-level lifting module. At this time, the speaker will broadcast a safety warning again. When the descent button is pressed a third time, the first-level lifting module lowers the first-level lifting device 1 to its lowest position.

[0084] Taking a two-level lifting device as an example, as shown in Figure 6, when the descent button is pressed for the first time, if the second-level lifting device 2 is not in its lowest position, a safety warning will be broadcast, such as checking whether there are people inside the lifting device's flaps, ladders, or tents, and whether anyone is approaching from the surrounding area. When the descent button is pressed a second time, if the first-level lifting device 1 is in its highest position, the main controller 31 executes the descent command for the second-level lifting device 2, causing the second-level lifting module to lower the second-level lifting device 2 to its lowest position. If the first-level lifting device 1 is not in its highest position, the main controller 31 first executes the ascent command for the first-level lifting device 1. After the first-level lifting module has raised the first-level lifting device 1 to its highest position, the main controller 31 then executes the descent command for the second-level lifting device 2, causing the second-level lifting device 2 to lower the second-level lifting module to its lowest position.

[0085] In this embodiment, the main control system 3 and the slave control system 4 adopt a single-master, single-slave control method, which effectively reduces wiring problems and provides greater flexibility in use through modularity. The power module 40 of the slave control system 4 can be removed separately for indoor charging, offering flexibility. Users can also equip multiple modules as needed, thus addressing battery anxiety. Furthermore, the main controller 31 in this embodiment has multiple reserved single-master, multi-slave control interfaces, allowing users to adjust the peripheral devices 5 as needed, enabling iterative updates without altering the overall architecture—a user-friendly design.

[0086] As mentioned above, the lifting device can be applied to multi-story lifting tents. Based on this, this disclosure also provides a vehicle-mounted tent using the above-mentioned lifting device and a control method thereof.

[0087] In some embodiments, for ease of explanation, a first direction, a second direction, and a lifting direction are defined, and these three directions are perpendicular to each other. However, those skilled in the art should understand that the embodiments of this disclosure are not limited to the case where these three directions are perpendicular to each other. For ease of explanation, as shown by the arrows in the figure, the direction where arrow X is located is the first direction, the direction where arrow Y is located is the second direction, and the direction where arrow Z is located is the lifting direction. Sometimes the lifting direction is also referred to as the height direction of the vehicle-mounted tent 100, and the direction pointed to by arrow Z along the lifting direction is referred to as "above" or "top side", and its opposite direction is referred to as "below" or "bottom side".

[0088] In some embodiments, when the vehicle tent 100 is installed on a vehicle in accordance with a set installation method, the lifting direction is parallel to the height direction of the vehicle (that is, the direction perpendicular to the driving surface of the vehicle), the first direction is parallel to the front-rear direction of the vehicle, and the second direction is parallel to the width direction of the vehicle.

[0089] This disclosure provides a vehicle-mounted tent 100 for installation on a vehicle. The vehicle can be any vehicle provided in the related art capable of carrying the vehicle-mounted tent 100 of this disclosure. The vehicle can include pure electric vehicles, hybrid vehicles, range-extended vehicles, fuel vehicles, etc. The vehicle type can also include small cars, mid-size cars, sedans, trucks, pickups, trailers, CDVs (Car Derived Vans), MPVs (Multi-Purpose Vehicles), SUVs (Sport Utility Vehicles), etc. This disclosure does not limit the specific type of vehicle.

[0090] In this disclosure, the description will mainly take the installation of the vehicle-mounted tent 100 on a pickup truck as an example. Here, a pickup truck specifically refers to a light truck with an open cargo box behind the cab.

[0091] Referring to Figures 7 to 9, the vehicle-mounted tent 100 of this embodiment includes a base 7, a first-layer lifting device 1, a second-layer lifting device 2, a lifting module 8, and a controller 91. The base 7, the first-layer lifting device 1, and the second-layer lifting device 2 are arranged sequentially opposite to each other along the lifting direction, and the base 7 is used to connect to a vehicle. The lifting module 8 is configured to drive the first-layer lifting device 1 and the second-layer lifting device 2 to move along the lifting direction, so that the vehicle-mounted tent 100 switches between an unfolded state and a stowed state. In the unfolded state, a first active space is formed between the first-layer lifting device 1 and the base 7, and a second active space is formed between the second-layer lifting device 2 and the first-layer lifting device 1.

[0092] Here, the arrangement of the base 7, the first-layer lifting device 1, and the second-layer lifting device 2 in sequence relative to each other along the lifting direction specifically means that the first-layer lifting device 1 is located on the top side of the base 7, and the second-layer lifting device 2 is located on the top side of the first-layer lifting device 1. In the same projection plane perpendicular to the lifting direction, the projection of the first-layer lifting device 1 at least partially overlaps with the projection of the base 7, and the projection of the second-layer lifting device 2 at least partially overlaps with the projection of the first-layer lifting device 1.

[0093] Referring to Figure 7, in the unfolded state, the base 7, the first-layer lifting device 1, and the second-layer lifting device 2 are arranged at intervals along the lifting direction, thereby forming a first movable space between the base 7 and the first-layer lifting device 1, and a second movable space between the first-layer lifting device 1 and the second-layer lifting device 2.

[0094] Referring to Figure 8, in the stowed state, the base 7, the first-layer lifting device 1, and the second-layer lifting device 2 abut against each other along the lifting direction, or are spaced apart along the lifting direction but the interval is much smaller than the interval in the unfolded state. This reduces the volume of the vehicle tent 100 in the lifting direction, thereby enabling the vehicle equipped with the vehicle tent 100 to drive normally when the vehicle tent 100 is in the stowed state without having to remove the vehicle tent 100.

[0095] In the stowed state, the lifting module 8 can perform an unfolding action, causing the first-layer lifting device 1 to rise relative to the base 7, and the second-layer lifting device 2 to rise relative to the first-layer lifting device 1, thereby switching the vehicle-mounted tent 100 from the stowed state to the unfolded state. In the unfolded state, the lifting module 8 performs a stowing action, causing the second-layer lifting device 2 to fall relative to the first-layer lifting device 1, and the first-layer lifting device 1 to fall relative to the base 7, thereby switching the vehicle-mounted tent 100 from the unfolded state to the stowed state.

[0096] The specific structure of the lifting module 8 is not limited, as long as it can perform the above-mentioned storage and unfolding actions.

[0097] The specific structural form of the base 7 can be determined by referring to the actual vehicle that needs to be adapted, as long as it can achieve the connection with the vehicle.

[0098] Taking the application of the vehicle-mounted tent 100 in a pickup truck as an example, the base 7 may specifically include a first support beam 71 and two second support beams 72. The two second support beams 72 extend along a first direction and are respectively connected to the opposite ends of the first support beam 71 along a second direction. The first support beam 71 is used to install to the front panel of the cargo box (the panel on the side closest to the cab), and the two second support beams 72 are respectively used to install to the two side panels of the cargo box along the width direction of the vehicle.

[0099] The first-level lifting device 1 and the second-level lifting device 2 are used to form a first activity space and a second activity space in the unfolded state. The specific structural forms of the two can be determined by those skilled in the art according to the actual desired activity space, and there are no restrictions on this.

[0100] As an example, referring to Figure 7, the first-layer lifting device 1 includes a base plate 11, and the second-layer lifting device 2 includes a top plate. The thickness directions of both the base plate 11 and the top plate are parallel to the lifting direction. Taking the vehicle-mounted tent 100 applied to a pickup truck as an example, in the same projection plane perpendicular to the lifting direction, the projections of the base plate 11, the top plate, and the cargo box roughly overlap. In this way, the total volume of the first and second activity spaces in the unfolded state can be maximized without affecting the normal form of the vehicle when the vehicle-mounted tent 100 is in the stowed state.

[0101] The controller 91 is electrically connected to the lifting module 8, and the controller 91 is used to execute the control method of the vehicle tent 100 to be described in any of the following embodiments.

[0102] In the vehicle-mounted tent 100 of this embodiment, the base 7, the first-layer lifting device 1, and the second-layer lifting device 2 can cooperate to form two layers of activity space, thereby expanding the activity space of the vehicle-mounted tent 100.

[0103] In some embodiments, the lifting module 8 includes a drive motor. For example, the lifting module 8 is configured as an electric actuator. Of course, in some other embodiments, the lifting module 8 may also include other structures such as cylinders, oil cylinders, hydraulic structures, etc., that can provide power for the lifting of the first-layer lifting device 1 and the second-layer lifting device 2.

[0104] In some embodiments, referring to FIG7, the lifting module 8 includes a first driving device 81 and a second driving device 82. The first driving device 81 is configured to drive the first-layer lifting device 1 to lift relative to the base 7, and the second driving device 82 is configured to drive the second-layer lifting device 2 to lift relative to the first-layer lifting device 1. The second driving device 82 and the first driving device 81 are configured to operate independently.

[0105] Here, the second drive device 82 and the first drive device 81 are configured to operate independently. Specifically, the second drive device 82 can operate when the first drive device 81 is not operating. In other words, the second drive device 82 can raise and lower the second lifting device 2 relative to the first lifting device 1 while the first lifting device 1 remains stationary relative to the base 7. Similarly, the first drive device 81 can operate when the second drive device 82 is not operating. In other words, the first drive device 81 can raise and lower the first lifting device 1 relative to the base 7 while the second lifting device 2 remains stationary relative to the first lifting device 1.

[0106] The advantage of setting the first drive device 81 and the second drive device 82 to operate independently is that it allows users to make the vehicle tents 100 form either the first activity space or the second activity space according to actual usage needs, and to independently adjust the dimensions of the first activity space and the second activity space along the height direction, thereby meeting the diverse usage needs of users.

[0107] The specific structural forms of the first driving device 81 and the second driving device 82 are not limited, as long as they can drive the corresponding components to rise and fall and can operate independently. The structural forms of the first driving device 81 and the second driving device 82 can be the same or different, and there is no restriction on this.

[0108] In this embodiment, it can be understood that the first driving device 81 and the second driving device 82 may each include at least one driving motor.

[0109] Of course, those skilled in the art will understand that in some other embodiments, the first driving device 81 and the second driving device 82 may also be configured to operate only synchronously.

[0110] In some embodiments, referring to Figures 7 and 8, specifically, the first driving device 81 includes at least one first scissor fork assembly 811 and a first power member 812. The first scissor fork assembly 811 is connected to the base 7 and the first floor lifting device 1, and the output end of the first power member 812 is connected to the first scissor fork assembly 811. And / or, the second driving device 82 includes at least one second scissor fork assembly 821 and a second power member 822. The second scissor fork assembly 821 is connected to the first floor lifting device 1 and the second floor lifting device 2, and the output end of the second power member 822 is connected to the second scissor fork assembly 821.

[0111] In this embodiment, a scissor fork structure is used to drive the first-layer lifting device 1 and / or the second-layer lifting device 2 to rise and fall. The advantage of the scissor fork structure is its high motion stability and reliability, thereby improving the reliability of the vehicle tent 100's functionality. On the other hand, the scissor fork structure can achieve a large lifting stroke within a limited space, which helps to reduce the volume of the vehicle tent 100 in the folded state and increase the volume of the vehicle tent 100 in the unfolded state.

[0112] It should be noted that the structural form of the first drive device 81 and the second drive device 82 is not limited to this. For example, the first drive device 81 and / or the second drive device 82 can also be configured as a rigid chain lifting mechanism, a hydraulic telescopic rod lifting mechanism, etc.

[0113] In this embodiment, the specific structural form of the first scissor fork assembly 811 and / or the second scissor fork assembly 821 is not limited. As an example, the first driving device 81 may include two first scissor fork assemblies 811 arranged opposite each other in a direction perpendicular to the lifting direction (e.g., the second direction). The number of first power members 812 may be two, respectively connected to the two first scissor fork assemblies 811. Alternatively, the number of first power members 812 may be one, connected to one of the first scissor fork assemblies 811 (in this case, the other scissor fork assembly may be set to passive movement), or simultaneously connected to both first scissor fork assemblies 811.

[0114] Similarly, the second drive device 82 may include two second scissor fork assemblies 821 arranged opposite each other in a direction perpendicular to the lifting direction (e.g., the second direction). The number of second power members 822 may be two, each connected to one of the two second scissor fork assemblies 821, or the number of second power members 822 may be one, connected to one of the second scissor fork assemblies 821, or connected to both second scissor fork assemblies 821 simultaneously.

[0115] The advantage of this configuration is that it improves the stability of the first-layer lifting device 1 and / or the second-layer lifting device 2 during the lifting process, thereby enhancing the reliability of the vehicle-mounted tent 100. On the other hand, the first scissor fork assembly 811 and / or the second scissor fork assembly 821 provide good support in the open state, allowing for the elimination of other supporting structures between the second-layer lifting device 2 and the first-layer lifting device 1, and / or between the first-layer lifting device 1 and the base 7. This simplifies the structure of the vehicle-mounted tent 100, meets the lightweight requirements of the vehicle-mounted tent 100, and reduces the load and energy consumption of the vehicle carrying the vehicle-mounted tent 100.

[0116] Of course, those skilled in the art should understand that the number of the first scissor fork assembly 811 and / or the second scissor fork assembly 821 may be one or more, and the number of the first scissor fork assembly 811 and the second scissor fork assembly 821 may be the same or different.

[0117] The first scissor fork assembly 811 and / or the second scissor fork assembly 821 can be specifically configured as an "X"-shaped scissor fork assembly, that is, including two scissor fork arms that are hinged to each other. Of course, those skilled in the art will understand that the scissor fork assembly may also include more scissor fork arms.

[0118] Taking the second scissor fork assembly 821 as an example, referring to Figure 7, the second scissor fork assembly 821 includes a first scissor fork arm 8211 and a second scissor fork arm 8212 hinged to each other. The fixed end of the first scissor fork arm 8211 is pivotally connected to the first-level lifting device 1, and the movable end is slidably engaged with the second-level lifting device 2 along a first direction. The fixed end of the second scissor fork arm 8212 is pivotally connected to the second-level lifting device 2, and the movable end is slidably engaged with the first-level lifting device 1 along a first direction. The fixed ends of the first scissor fork arm 8211 and the second scissor fork arm 8212 are located on the same side along the first direction.

[0119] The structure of the first power component 812 and the second power component 822 is not limited. As mentioned above, the first power component 812 and the second power component 822 may include a drive motor.

[0120] In some embodiments, referring to FIG7, the first-layer lifting device 1 includes a substrate 11 and at least one extension plate 12 disposed on the substrate 11. The extension plate 12 is movably connected to the substrate 11 so that the extension plate 12 can move between a first position and a second position. Referring to FIGS. 7 and 8, in the first position, the extension plate 12 and the substrate 11 are arranged side by side along a first direction. In the second position, in the orthographic projection along the lifting direction, the projection of the extension plate 12 at least partially overlaps with the projection of the substrate 11. In the retracted state, the extension plate 12 is located in the second position.

[0121] Here, in the first position, the extension plate 12 and the substrate 11 are arranged side by side along the first direction, which specifically means that in the first position, the thickness directions of the extension plate 12 and the substrate 11 are parallel (for example, both are parallel to the lifting direction), and the extension plate 12 and the substrate 11 are distributed along the first direction.

[0122] The number of expansion plates 12 is not limited. In the embodiments shown in Figures 7 and 8, there are two expansion plates 12. In the first position, the two expansion plates 12 are located on opposite sides of the substrate 11 along the first direction. Of course, in some other embodiments, there may be only one expansion plate 12. In some other embodiments, the first layer lifting device 1 may also include more expansion plates 12. In the first position, at least one expansion plate 12 is arranged side by side with the substrate 11 along the second direction.

[0123] The specific manner in which the extension plate 12 is movably connected to the substrate 11 is not limited, as long as it enables the extension plate 12 to move between the aforementioned first and second positions. As an example, the extension plate 12 is configured to rotate relative to the substrate 11 about a second direction; in the second position, the extension plate 12 can be located on the top or bottom side of the substrate 11 along the lifting direction. As another example, the extension plate 12 and the substrate 11 are slidably engaged along the first direction; in the second position, the extension plate 12 is located on the top or bottom side of the substrate 11 along the lifting direction. Alternatively, the substrate 11 has a receiving cavity open on at least one side along the first direction; in the second position, the extension plate 12 is located within the receiving cavity.

[0124] The extension plate 12 can be configured to move between a first position and a second position under the drive of a corresponding drive structure, or the extension plate 12 can be configured to move between the first position and the second position by manual operation by the user. In other words, the vehicle tent 100 may not include a drive structure for driving the extension plate 12.

[0125] It is understandable that the surface area of ​​the base 7, the first-level lifting device 1, and the second-level lifting device 2 perpendicular to the lifting direction is limited by the vehicle size. Taking a pickup truck as an example, the aforementioned surface area of ​​the base 7, the first-level lifting device 1, and the second-level lifting device 2 will be limited by the size of the cargo box. More specifically, in the folded state, in the projection plane perpendicular to the lifting direction, the projections of the base 7, the first-level lifting device 1, and the second-level lifting device 2 should not exceed the projection of the cargo box in either the first or second direction.

[0126] In this embodiment, in the stowed state, the extension plate 12 is located in the second position, which ensures that the first-layer lifting device 1 can meet the size requirements in the stowed state. In the unfolded state, the extension plate 12 can move to the first position, which allows the surface area of ​​the first-layer lifting device 1 perpendicular to the lifting direction to no longer be limited by the vehicle size, thereby expanding the range of the second activity space.

[0127] Taking a pickup truck as an example, in the first position, on the same projection plane perpendicular to the lifting direction, the projection of the extension plate 12 extends beyond the projection of the cargo box along the first direction.

[0128] In some embodiments, referring to FIG7, the vehicle tent 100 includes an anti-pinch strip 92. At least one of the base 7, the first-layer lifting device 1, and the second-layer lifting device 2 is provided with the anti-pinch strip 92, and the anti-pinch strip 92 is electrically connected to the controller 91.

[0129] The anti-pinch strip 92 is mainly used to prevent the user from being pinched during the transition of the vehicle tent 100 from the unfolded state to the folded state, thereby improving the safety of the vehicle tent 100. As an example, a pressure sensor can be installed inside the anti-pinch strip 92, and the pressure sensor is electrically connected to the controller 91.

[0130] In some embodiments, specifically, the base 7 is provided with an anti-pinch strip 92 on one end face of the first-layer lifting device 1 along the lifting direction (e.g., the top face of the first support beam 71 and / or the second support beam 72).

[0131] The advantage of having an anti-pinch strip 92 on the base 7 is that the anti-pinch strip 92 can be triggered even when the user is outside the vehicle tent 100 and touches the base 7, thereby helping to further improve the safety of use.

[0132] In some embodiments, referring to FIG7, the base plate 11 of the first layer lifting device 1 may have a communication port 11a for connecting the first active space and the second active space. The first layer lifting device 1 includes a cover plate 13 movably connected to the base plate 11, and the cover plate 13 is used to close the communication port 11a.

[0133] The specific way in which the cover plate 13 is movably connected to the base plate 11 is not limited, such as sliding connection, rotational connection, etc.

[0134] Furthermore, referring to Figure 10, the vehicle-mounted tent 100 may include a first sensor 93 for detecting whether the communication port 11a is closed, and the first sensor 93 is electrically connected to the controller 91. It should be noted that only a part of the structure of the first sensor 93 is shown in Figure 10, while other structures of the first sensor 93 (such as the housing) are hidden.

[0135] Here, the specific structure of the first sensor 93 is not limited, as long as it can detect whether the connecting port 11a is closed.

[0136] In some embodiments, specifically referring to FIG10, the first sensor 93 includes a first reed switch 931, also known as a reed switch, which is an electrical switch operated by an applied magnetic field. As an example, the first sensor 93 includes a first magnet 932. The first magnet 932 is disposed on one of the substrate 11 and the cover plate 13, and the first reed switch 931 is disposed on the other. When the cover plate 13 is in the position of closing the communication port 11a, the first magnet 932 approaches the first reed switch 931, causing the first reed switch 931 to close, thereby sending an electrical signal to the controller 91.

[0137] It is understandable that the cover plate 13 typically experiences significant inertial force during closure. Using contact-type sensors (such as pressure sensors or microswitches) may pose a high risk of damage and could lead to false detections due to assembly tolerances. Conversely, using other types of non-contact sensors (such as Hall effect sensors) may result in weak output signals and long wiring distances, leading to signal instability. In this disclosure, the first sensor 93 includes a reed switch. The reed switch does not require direct contact with the cover plate 13, thus reducing the risk of damage and lowering the probability of false detections due to assembly tolerances. Furthermore, it generates a strong output signal, providing a more stable signal to the controller 91.

[0138] In some embodiments, referring to Figures 7, 8 and 11, the vehicle-mounted tent 100 further includes an auxiliary ladder 94 and a second sensor 95.

[0139] The auxiliary ladder 94 has a supported state. In the supported state, the two ends of the auxiliary ladder 94 along the lifting direction are respectively supported by the base 7 and the first floor lifting device 1, so that the user can climb from the first activity space to the second activity space with the help of the auxiliary ladder 94.

[0140] The auxiliary ladder 94 can also have a retracted state, in which the auxiliary ladder 94 will no longer provide support, thereby allowing the first-floor lifting device 1 to descend relative to the base 7.

[0141] As an example, referring to Figure 7, the auxiliary ladder 94 includes a first rigid section 941 and a second rigid section 942, which are rotatably connected and rotatably connected to the base 7 and the first-floor lifting device 1, respectively. In the supported state, the first rigid section 941 and the second rigid section 942 of the auxiliary ladder 94 abut against each other along the lifting direction, thereby providing support. In the retracted state, the first rigid section 941 and the second rigid section 942 of the auxiliary ladder 94 can rotate relative to each other, thereby folding the auxiliary ladder 94 and no longer providing support. In this embodiment, the auxiliary ladder 94 may further include a locking member for locking the first rigid section 941 and the second rigid section 942 in the supported state.

[0142] The second sensor 95 is used to detect whether the auxiliary ladder 94 is in the above-mentioned support state. The second sensor 95 is electrically connected to the controller 91.

[0143] The specific structure of the second sensor 95 is not limited, as long as it can detect whether the auxiliary ladder 94 is in a supported state.

[0144] Taking the auxiliary ladder 94, which includes the aforementioned first rigid section 941 and second rigid section 942, as an example, the second sensor 95 can be disposed on the end faces of the first rigid section 941 and the second rigid section 942 facing each other in the lifting direction when in a supported state. Alternatively, the second sensor 95 can be disposed at the rotatable connection between the first rigid section 941 or the second rigid section 942 and the corresponding base 7. In some embodiments, specifically, the second rigid section 942 is rotatably connected to the first floor lifting device 1, and the second sensor 95 is disposed at the rotatable connection between the second rigid section 942 and the first floor lifting device 1, thereby improving the reliability of detection.

[0145] In some embodiments, specifically referring to FIG11, the second sensor 95 includes a second reed switch 951. It should be noted that FIG11 only shows a portion of the structure of the first sensor 93, while other structures of the second sensor 95 (such as the housing) are hidden.

[0146] It is understandable that the auxiliary ladder 94 provides support for the base 7 and the first-floor lifting device 1 when in a supported state, and the user needs to climb using the auxiliary ladder 94. This results in the auxiliary ladder 94 having a large inertial force. Using contact-type sensors (such as pressure sensors, microswitches, etc.) may pose a high risk of damage and may lead to false detections due to assembly tolerance issues. On the other hand, using other types of non-contact sensors (such as Hall sensors) may result in signal instability due to weak output signals and long wiring distances. In this disclosure, the second sensor 95 includes a second reed switch 951. The reed switch does not need to directly contact the auxiliary ladder 94, thus reducing the risk of damage and lowering the probability of false detections due to assembly tolerances. Furthermore, it can generate a strong output signal, thereby providing a more stable signal to the controller 91.

[0147] As an example, the second sensor 95 includes a second reed switch 951 and a second magnet 952. Taking the second sensor 95 as an example where the second rigid section 942 is located at the rotatable connection between the first layer lifting device 1 and the second rigid section 942, one of the second reed switch 951 and the second magnet 952 is fixed to the first layer lifting device 1 and the other is fixed to the second rigid section 942.

[0148] The embodiments of this disclosure also provide a control method for a vehicle-mounted tent 100. Referring to FIG12, the control method for a vehicle-mounted tent 100 of the embodiments of this disclosure includes the following steps.

[0149] Step S101: In response to the storage command, the lifting module 8 performs a storage action to lower the first-layer lifting device 1 and the second-layer lifting device 2.

[0150] Step S102: During the storage action of the lifting module 8, obtain the operating parameters of the lifting module 8.

[0151] Step S103: Determine whether there is a collision risk based on the operating parameters. If a collision risk is determined, stop the lifting module 8 from performing the storage action.

[0152] As mentioned above, the vehicle-mounted tent 100 of this embodiment can provide two layers of activity space when unfolded. However, this presents a problem: there are certain safety risks when controlling the vehicle-mounted tent 100 to switch to a stowed state. Specifically, due to the large activity space, when the user controls the vehicle-mounted tent 100 to stow it from outside the activity space, there may be a large blind spot, making it difficult to determine whether there are still living beings in the activity space, especially whether there are still living beings in the second activity space. This may lead to a collision risk during the stowage process, resulting in injury to the user or other living beings.

[0153] To this end, a control method for a vehicle-mounted tent 100 according to an embodiment of the present disclosure is provided. As an example, the control method for a vehicle-mounted tent 100 according to an embodiment of the present disclosure can be applied to the vehicle-mounted tent 100 described in any of the above embodiments and executed by the controller 91 of the vehicle-mounted tent 100 described in any of the above embodiments.

[0154] In step S101, specifically, in response to the storage command, the lifting module 8 performs a storage action.

[0155] Here, the storage command can be a command sent by the user through the remote control of the vehicle tent 100, the relevant control buttons on the vehicle tent 100, or through the application software installed on a mobile terminal (such as a mobile phone, tablet computer, laptop computer, wearable device, etc.), and there is no limitation on this.

[0156] Here, making the lifting module 8 perform the storage action specifically means that the lifting module 8 drives the second-layer lifting device 2 to descend relative to the first-layer lifting device 1, and the first-layer lifting device 1 to descend relative to the base 7, thereby switching the vehicle tent 100 from the unfolded state to the stored state. Specifically, the lifting module 8 can be made to perform the above storage action by sending corresponding control commands to the lifting module 8.

[0157] In step S102, during the process of the lifting module 8 performing the storage action, the operating parameters of the lifting module 8 are obtained. Here, the operating parameters can be any parameters that can reflect the operating status of the lifting module 8. Taking the lifting module 8 including the drive motor as an example, the operating parameters can be the electrical parameters of the drive motor, etc.

[0158] It can be understood that obtaining the operating parameters of the lifting module 8 during the process of performing the storage action means continuously (e.g., continuously sampling at a fixed or variable sampling frequency) obtaining the operating parameters of the lifting module 8 throughout the entire process of performing the storage action, until the storage action is completed, that is, until the vehicle tent 100 switches to the storage state.

[0159] In step S103, the system determines whether there is a collision risk based on the operating parameters. If a collision risk is determined, the lifting module 8 stops performing the storage action.

[0160] It is understandable that if the first-layer lifting device 1 and / or the second-layer lifting device 2 touch an obstacle during the storage operation of the lifting module 8, the load on the lifting module 8 will increase, which will in turn cause the operating parameters of the lifting module 8 to change. Therefore, the operating parameters of the lifting module 8 can be used to determine whether there is a collision risk. If a collision risk is determined, the lifting module 8 can be stopped from performing the storage operation to avoid a collision.

[0161] When determining whether there is a collision risk based on the operating parameters, the specific determination method can be determined by those skilled in the art according to the specific structural form of the lifting module 8 used and the specific types of the actually selected operating parameters, and no limitation is imposed thereon.

[0162] The vehicle-mounted tent 100 and its control method according to the embodiments of the present disclosure can provide a relatively large activity space, and can avoid the collision risk problems that may be caused by the visual blind area in the activity space as much as possible through collision risk detection, improve the activity space of the vehicle-mounted tent 100, and improve the use safety and reliability of the vehicle-mounted tent 100.

[0163] Furthermore, in the vehicle-mounted tent 100 and its control method according to the embodiments of the present disclosure, when determining whether there is a collision risk based on the operating parameters of the lifting module 8, compared with the solution of determining whether there is a living body by means of, such as, infrared detection signals, radar detection signals, load-bearing signals, etc., and then determining whether there is a collision risk, the use cost and the misjudgment probability are low (infrared detection may be misjudged due to the influence of sunlight, radar detection signals may be misjudged due to the self-movement of the vehicle-mounted tent 100, such as the shaking of the tarpaulin, etc., and load-bearing signals may be misjudged due to the self-assembly tolerance, movement, load difference, etc. of the vehicle-mounted tent 100). Therefore, it helps to reduce the cost and improve the accuracy and reliability of collision risk judgment.

[0164] In some embodiments, as mentioned above, the lifting module 8 includes a driving motor. In this embodiment, specifically, the operating parameters include the electrical parameters of the driving motor, and the electrical parameters include at least one of current value, output power, and torque.

[0165] It can be understood that if the first-layer lifting device 1 and / or the second-layer lifting device 2 touches an obstacle during the descending process, the load of the driving motor will change, and the above-mentioned electrical parameters will all change accordingly with the change of the load of the driving motor. Therefore, it is possible to determine whether there is a collision risk through the above-mentioned electrical parameters.

[0166] The advantage of using the electrical parameters of the driving motor as the operating parameters is that the acquisition difficulty is relatively low and the accuracy is relatively high. Therefore, it helps to further improve the use safety and reliability of the vehicle-mounted tent 100 and reduce the cost at the same time.

[0167] In some embodiments, obtaining the operating parameters of the lifting module 8 specifically includes: obtaining the first electrical parameter and the second electrical parameter of the driving motor, where the first electrical parameter is the electrical parameter at the current moment, and the second electrical parameter is the electrical parameter at the previous moment. Determining whether there is a collision risk based on the operating parameters includes: obtaining the difference between the first electrical parameter and the second electrical parameter, and if the difference is greater than a preset value, it is determined that there is a collision risk.

[0168] Here, the time interval between the current moment and the previous moment can be specifically determined by those skilled in the art according to actual usage requirements, and there is no limitation on this.

[0169] The preset value can be specifically determined by those skilled in the art according to the electrical parameters and their variation rules during the normal operation of the lifting module 8, and there is no limitation on this.

[0170] It can be understood that during the normal operation of the lifting module 8, the electrical parameters will also change to a certain extent with the changes formed by the movement. Therefore, in this embodiment, the difference between the electrical parameters obtained at two adjacent moments is used to determine whether there is a collision risk, rather than relying on the absolute value of the electrical parameters to determine whether there is a collision risk. In this way, it helps to further reduce the possibility of misjudgment, thereby further improving the accuracy and reliability of the collision risk judgment.

[0171] In some embodiments, as mentioned above, the vehicle-mounted tent 100 further includes an anti-pinch strip 92, and at least one of the base 7, the first lifting device 1, and the second lifting device 2 is provided with the anti-pinch strip 92. In this embodiment, the control method of the vehicle-mounted tent 100 further includes: during the process of the lifting module 8 performing the storage action, obtaining the operating state of the anti-pinch strip 92; if the anti-pinch strip 92 is in a triggered state, then making the lifting module 8 stop performing the storage action.

[0172] Taking the anti-pinch strip 92 including a pressure sensor as an example, the anti-pinch strip 92 being in a triggered state specifically means that the pressure monitored by the pressure sensor of the anti-pinch strip 92 is greater than the threshold value.

[0173] In this embodiment, further借助防夹条92(这里原文“借助防夹条92”表述有误,推测是“by means of the anti-pinch strip 92”) to assist in judging whether there is a collision risk, which helps to further improve the use safety of the vehicle-mounted tent 100. In addition, it can be understood that when judging whether there is a collision risk according to the operating parameters of the lifting module 8, it may be necessary to complete the judgment only after the first lifting device 1 and / or the second lifting device 2 actually come into contact with a living body. The advantage of the anti-pinch strip 92 is that if the user finds that the first lifting device 1 and / or the second lifting device 2 is descending and there is danger to himself, he can actively trigger the anti-pinch strip 92 to prevent the vehicle-mounted tent 100 from continuing to descend, thereby further improving the safety performance.

[0174] Moreover, in the embodiment where the anti-pinch strip 92 is provided on the first support beam 71 and / or the second support beam 72 of the base 7, the anti-pinch strip 92 can further prevent the vehicle-mounted tent 100 from descending when the user is outside the vehicle-mounted tent 100 and is moving close to the vehicle-mounted tent 100.

[0175] In some embodiments, after the lifting module 8 stops performing the storage action, the control method of the vehicle-mounted tent 100 further includes: causing the lifting module 8 to perform an unfolding action to raise the first-layer lifting device 1 and / or the second-layer lifting device 2.

[0176] Specifically, causing the lifting module 8 to perform the unfolding action means causing the second-layer lifting device 2 to rise relative to the first-layer lifting device 1 and / or causing the first-layer lifting device 1 to rise relative to the base 7.

[0177] Here, causing the lifting module 8 to perform the unfolding action can be causing the lifting module 8 to perform the unfolding action until the vehicle-mounted tent 100 returns to the unfolded state, or causing the lifting module 8 to perform the unfolding action and stopping the lifting module 8 from performing the unfolding action after the first-layer lifting device 1 and / or the second-layer lifting device 2 rise by a certain amount (but do not return to the unfolded state). Those skilled in the art can specifically determine according to actual usage requirements.

[0178] In this embodiment, in a situation where there is a risk of collision, further causing the lifting module 8 to perform the unfolding action, thereby facilitating users or other organisms to leave the vehicle-mounted tent 100. [[ID=eleven]]

[0179] In some embodiments, as mentioned above, the lifting module 8 includes a first driving device 81 and a second driving device 82. The first driving device 81 is configured to drive the first-layer lifting device 1 to lift and lower relative to the base 7, and the second driving device 82 is configured to drive the second-layer lifting device 2 to lift and lower relative to the first-layer lifting device 1. The second driving device 82 and the first driving device 81 are configured to be able to act independently. In such an embodiment, step S101 in response to a storage instruction causing the lifting module 8 to perform the storage action specifically includes:

[0180] In response to the storage instruction, causing the second driving device 82 to perform the storage action, and in response to the first-layer lifting device 1 descending to the lowest point, causing the first driving device 81 to perform the storage action.

[0181] In this embodiment, the first-layer lifting device 1 and the second-layer lifting device 2 do not descend synchronously. Instead, the second-layer lifting device 2 first completes its descent, and then the first-layer lifting device 1 starts to descend. This descending method can avoid the situation where there is an organism in the second activity space and the first-layer lifting device 1 descends, causing the organism to be unable to stand firm. Thus, it helps to further improve the usage safety of the vehicle-mounted tent 100.

[0182] In some embodiments, as a supplement or alternative, step S101 may include: in response to a first storage instruction, causing the first driving device 81 to perform the storage action; in response to a second storage instruction, causing the second driving device 82 to perform the storage action.

[0183] In this embodiment, the user is allowed to separately control the first driving device 81 and the second driving device 82 for storage through an independent storage instruction. Thus, on the one hand, it helps to improve the use safety, and on the other hand, it helps to expand the use scenarios of the vehicle-mounted tent 100. For example, it can be realized to use the first activity space alone without unfolding the second activity space.

[0184] It should be noted that the above two storage schemes do not conflict. For example, in response to the third storage instruction, the second execution device can be made to perform the storage action. In response to the second layer lifting device 2 descending to the lowest point, the first driving device 81 can be made to perform the storage action.

[0185] In some embodiments, step S101 can further include: in response to the fourth control instruction, making the first driving device 81 and the second driving device 82 perform the storage action synchronously. That is, the user is allowed to actively select to make the first layer lifting device 1 and the second layer lifting device 2 descend synchronously to meet the rapid storage requirements in special cases.

[0186] Those skilled in the art can flexibly select the above storage schemes according to actual usage requirements.

[0187] Furthermore, in the above embodiment, the control method of the vehicle-mounted tent 100 can further include: in response to the first unfolding instruction, making the first driving device 81 perform the unfolding action; and / or, in response to the second unfolding instruction, making the second driving device 82 perform the unfolding action; and / or, in response to the third unfolding instruction, making the first driving device 81 perform the unfolding action, and in response to the first layer lifting device 1 rising to the highest point, making the second driving device 82 perform the unfolding action; and / or, in response to the fourth unfolding instruction, making the first driving device 81 and the second driving device 82 perform the unfolding action synchronously.

[0188] In the above embodiment, judging whether there is a collision risk according to the operation parameters includes respectively judging whether there is a collision risk according to the operation parameters of the first driving device 81 and the second driving device 82.

[0189] Taking the example that both the first driving device 81 and the second driving device 82 include driving motors, it can be respectively judged whether there is a collision risk according to the electrical parameters of the first driving device 81 and the second driving device 82. The specific judgment method can refer to the description of the relevant part in the above text and will not be elaborated here.

[0190] It is understandable that if a collision risk is determined based on the operating parameters of the first drive device 81, only the first drive device 81 can be controlled to stop performing the storage action, and further, only the first drive device 81 can be controlled to perform the deployment action. Similarly, if a collision risk is determined based on the operating parameters of the second drive device 82, only the second drive device 82 can be controlled to stop performing the storage action, and further, only the second drive device 82 can be controlled to perform the deployment action.

[0191] Of course, in the embodiment where the first driving device 81 and the second driving device 82 move synchronously, if a collision risk is determined based on the operating parameters of either the first driving device 81 or the second driving device 82, the first driving device 81 and the second driving device 82 can be stopped from performing the storage action simultaneously.

[0192] In some embodiments, as mentioned above, the first-layer lifting device 1 includes a base plate 11 and a cover plate 13 movably connected to the base plate 11. The base plate 11 has a connection for communicating between a first active space and a second active space, and the cover plate 13 is used to close the communication port 11a. In this embodiment, responding to a storage command, causing the lifting module 8 to perform a storage action may include: responding to the storage command, determining whether the communication port 11a is closed; if it is determined that the communication port 11a is not closed, then preventing the lifting module 8 from performing the storage action.

[0193] In this embodiment, the closure of the connection port 11a can be determined by communicating with the first sensor 93.

[0194] It is understandable that if the connecting port 11a is not closed, it may mean that there is a living organism in the second activity space. In addition, there is a risk that the second-layer lifting device 2 may collide with the cover plate 13 during the descent. Therefore, in this embodiment, before the lifting module 8 performs the storage action, it is determined whether the connecting port 11a is closed to avoid the vehicle tent 100 from descending when the connecting port 11a is not closed, thereby further improving the safety of the vehicle tent 100.

[0195] In some embodiments, as mentioned above, the vehicle-mounted tent 100 includes an auxiliary ladder 94, which has a supported state. In the supported state, the two ends of the auxiliary ladder 94 along the lifting direction are respectively supported by the base 7 and the first-level lifting device 1. In this embodiment, responding to a storage command and causing the lifting module 8 to perform a storage action may include: responding to the storage command and determining whether the auxiliary ladder 94 is in a supported state; if it is determined that the auxiliary ladder 94 is in a supported state, then preventing the lifting module 8 from performing the storage action.

[0196] In this embodiment, the auxiliary ladder 94 can be determined to be in a supported state by communicating with the second sensor 95.

[0197] It is understandable that when the auxiliary ladder 94 is in a supported state, it may mean that there is a living organism in the second activity space. In addition, it helps the auxiliary ladder 94 to have a certain supporting capacity. However, there may also be risks such as the first-floor lifting device 1 descending and causing damage to the auxiliary ladder 94, damage to the lifting module 8 (e.g., drive motor stalling), or the first-floor lifting device 1 tilting. Therefore, in this embodiment, before the lifting module 8 performs the storage action, it is first determined whether the auxiliary ladder 94 is in a supported state to avoid the vehicle tent 100 descending when the auxiliary ladder 94 is in a supported state, thereby further improving the safety of the vehicle tent 100.

The processor 202 typically controls the overall operation of the electronic device 200. The communication interface enables the electronic device 200 to communicate with other terminals or servers via a network. The memory 201 is configured to store instructions and applications executable by the processor 202, and can also cache data to be processed or already processed by the processor 202 and various modules within the electronic device 200 (e.g., image data, audio data, voice communication data, and video communication data). This data can be implemented using flash memory (FLASH) or random access memory (RAM).
