[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0032] It should be understood that the terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0033] It will also be understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0034] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0035] In recent years, with the improvement of people's living standards, more and more young people enjoy outdoor activities such as hiking, camping, and picnics. These activities often require manual movement of tents and food, or the use of manually pulled levers to move camper vans. With the increasing popularity of camping, camping equipment is becoming increasingly comprehensive. Relying on manual labor to move large amounts of camping equipment or pull heavy camper vans in complex camping environments significantly impacts physical strength and the quality of outdoor activities. Consequently, the demand for camper vans with electric controls is growing.

[0036] In the related art, existing electric campers typically mount the battery and controller externally on the vehicle body, securing them to the vehicle body with screws or other means. However, this external placement increases the size of the electric camper, affecting its aesthetics. It also inevitably exposes the connecting wires between the controller, battery, and motor wheel to the air, which accelerates their aging. Furthermore, in humid environments, the externally mounted battery and controller are susceptible to water ingress, resulting in poor waterproofing.

[0037] To address the aforementioned issues, embodiments of the present application provide an electric camper. By disposing a control module and a battery module within the pillar structure of the electric camper, the control module and battery module, along with their corresponding connecting cables, can be built into the vehicle frame. This not only reduces the size of the electric camper but also prevents aging of the connecting cables and enhances waterproofness, thereby improving the user experience.

[0038] Exemplarily, the electric camper may include a remote-controlled electric camper or a lever-controlled electric camper, which is not specifically limited herein.

[0039] The specific structures of the electric camper will be described in detail below.

[0040] See also Figure 1-Figure 3 , Figure 1 1 is a structural diagram of an electric camper 100 provided in an embodiment of the present application. Figure 2 This is a schematic structural diagram of an electric camper 100 provided in an embodiment of the present application. Figure 3 FIG. 1 is a schematic diagram of the structure of an electric camper 100 provided in an embodiment of the present application. Figure 1-Figure 3 As shown, the electric camper 100 includes a vehicle body 10, a wheel module 20, a control module 30 and a battery module 40. The vehicle body 10 includes at least a frame 12 and a vehicle body 11. The frame 12 can be used to support and fix the vehicle body 11. The frame 12 can form an area that matches the shape of the vehicle body 11 so that the vehicle body 11 can be installed and fixed in the area. The vehicle body 11 is used to place camping items. The frame 12 includes a column structure 120. The shape of the vehicle body 11 can be square, rectangular, trapezoidal, etc., which is not specifically limited here. The frame 12 can include one or more column structures 120, but based on aesthetics and stability considerations, taking the shape of the vehicle body 11 as a rectangle as an example, column structures 120 are generally provided at the four corner points of the vehicle body 11.

[0041] The wheel module 20 includes a wheel. The wheel module 20 is connected to the car body 10. The wheel is used to drive the car body 10 to move. The wheel may include a motor wheel 21 and a universal wheel. The control module 30 is arranged in the column structure 120. The control module 30 is used to drive the motor wheel 21 to move. Since the control module 30 is built into the column structure 120, the control module 30 can be hidden by the column structure 120. The battery module 40 is arranged in the column structure 120. The battery module 40 is connected to the control module 30 and is used to power the control module 30. Since the battery module 40 is built into the column structure 120, the battery module 40 can be hidden by the column structure 120.

[0042] It should be noted that the battery module 40 and the control module 30 can be arranged in the same column structure 120 or in different column structures 120, which is not specifically limited here.

[0043] The electric camper 100 provided in the embodiment of the present application integrates the control module 30 and the battery module 40 within the column structure 120. This allows the control module 30, the battery module 40, and their corresponding connecting cables to be built into the vehicle frame 12. This allows the control module 30 and the battery module 40 to be hidden and protected by the column structure 120. Furthermore, the column structure 120 allows for internal wiring between the control module 30 and the battery module 40, completely concealing the connecting cables within the vehicle frame 12 and preventing them from being exposed to the air. This arrangement not only reduces the size of the electric camper 100 but also prevents aging of the connecting cables and enhances waterproofness, thereby improving the user experience.

[0044] like Figure 3 and Figure 4As shown, the battery module 40 is detachably connected to the column structure 120 and includes a battery housing 41, a battery cell assembly 42, and an electronic control board 43. A charging port 410 and a discharging port 411 are provided at one end of the battery housing 41, and a connection port 412 is provided at the other end of the battery housing 41. The battery housing 41 is adapted to the shape of the column structure 120 so that the battery module 40 can be installed in the column structure 120. The battery cell assembly 42 is provided in the battery housing 41. The electronic control board 43 is provided in the battery housing 41 and is electrically connected to the battery cell assembly 42. The electronic control board 43 includes a charging port, a discharging port, and a power supply port. The charging port, the discharging port, and the power supply port correspond to the charging port 410, the discharging port 411, and the connection port 412, respectively. The charging port is used to charge the battery cell assembly 42, the discharging port is used to charge external devices, and the power supply port is used to power the control module 30.

[0045] The charging port is configured to correspond to the charging port 410, the discharging port is configured to correspond to the discharging port 411, and the power supply port is configured to correspond to the power supply port. The external device may be a computer, a mobile phone, a desk lamp, or other device that needs to be charged.

[0046] Exemplarily, the electric control board 43 may be any circuit board or chip with a control function.

[0047] It should be noted that the charging port 410 and the discharging port 411 can be any interface that can be used for charging or discharging, such as a USB-A port or a USB-C port, and are not specifically limited here.

[0048] Specifically, when the charging port 410 is connected to an external power source, the electric control board 43 controls the charging port to charge the battery cell assembly 42 through the external power source connected to the charging port 410; when the discharge port 411 is connected to an external device, the electric control board 43 controls the discharge port to charge the external device connected to the discharge port 411 through the battery cell assembly 42; when the electric camper 100 starts working, the electric control board 43 controls the power supply port to supply power to the control module 30 through the battery cell assembly 42.

[0049] The battery module 40 of an existing electric camper 100 is typically mounted on the vehicle body 100 and often only functions to power the control module 30. Consequently, the existing battery module 40 suffers from a single functionality and limited application scenarios. However, the battery module 40 of the electric camper 100 provided in this application can be hidden within the column structure 120, which does not increase the size of the camper and is less susceptible to water ingress. Not only does it meet the power supply requirements for the control module 30, but it can also be detached from the column structure 120 and used as a power bank to charge external devices, preventing users from losing their electronic devices due to a dead battery while camping. Furthermore, users do not need to carry an additional power bank, reducing their camping burden.

[0050] Specifically, the battery housing 41 is further provided with an indicator light, which is electrically connected to the electric control board 43 and is used to display the power level of the battery module 40 .

[0051] For example, the indicator light can be used to display the power level of the battery module 40 , thereby reminding the user to charge the battery module 40 , or reminding the user to use the battery module 40 to charge an external device.

[0052] Specifically, the battery housing 41 is further provided with a charging switch button, which is electrically connected to the electric control board 43 ; the electric control board 43 is used to charge the external device in response to the pressing operation of the charging switch button.

[0053] For example, the user may press a charging switch button to activate the charging function of the battery module 40 to charge the connected external device.

[0054] Specifically, the battery module 40 further includes a protective cover plate, which is pluggably connected to the battery housing 41 , and is used to cover the charging port 410 and the discharging port 411 .

[0055] For example, the protective cover may cover the charging port 410 and the discharging port 411 when the battery module 40 is not being charged or discharged, thereby protecting the charging port 410 and the discharging port 411 from damage.

[0056] like Figure 5 As shown, in some embodiments, a power button 124 is provided on the surface of the pillar structure 120. The power button 124 is used to open or close the circuit between the battery module 40 and the control module 30. The battery module 40 is used to supply power to the control module 30 in response to pressing the power button 124. This prevents the battery module 40 from immediately supplying power to the control module 30 when it is inserted into the pillar structure 120, thereby driving the electric camper 100 to start moving.

[0057] Because the battery module 40 provided in the embodiment of the present application can be used as a power bank, the user may insert the battery module 40 back into the column structure 120 after the battery module 40 has finished charging an external device. If the remote control 53 accidentally triggers a movement command, or if the electric camper 100 mistakenly receives a movement command due to other factors, the battery module 40 will immediately power the control module 30, causing the control module 30 to immediately drive the electric camper 100 to start moving, which may be dangerous. However, the embodiment of the present application provides a power button 124 on the surface of the column structure 120. Only after the user presses the power button 124 will the circuit between the battery module 40 and the control module 30 be connected, allowing the battery module 40 to power the control module 30, thereby improving the safety of the electric camper 100.

[0058] For example, when the user does not need the battery module 40 to power the control module 30, the user can also press the power button 124 to disconnect the circuit between the battery module 40 and the control module 30, so that the battery module 40 stops powering the control module 30, thereby improving the safety of the electric camper 100.

[0059] In some embodiments, the electric camper 100 further includes an adapter module, which is disposed within the column structure 120 and is configured to connect to the battery module 40 via the connection port 412 ; the battery module 40 supplies power to the control module 30 via the adapter module.

[0060] Exemplarily, the adapter module can be set in the column structure 120 including the battery module 40, and the adapter module can be set at the bottom of the column structure 120 to support the battery module 40, while being able to be connected to the battery module 40 through the connection port 412 and power the control module 30 through the internal wiring of the frame 12.

[0061] In some embodiments, the battery module 40 further includes a magnetic member, which is disposed at the other end of the battery housing 41 , and the battery housing 41 is configured to be magnetically connected to the column structure 120 via the magnetic member.

[0062] Illustratively, a magnetic member is provided at the other end of the battery housing 41 for magnetically engaging with the pillar structure 120 , thereby enabling the battery module 40 to be quickly installed into the pillar structure 120 through magnetic engagement.

[0063] like Figure 3 As shown, in some embodiments, the pillar structure 120 includes a first pillar and a second pillar, the control module 30 is disposed in the first pillar, and the battery module 40 is disposed in the second pillar. Thus, the control module 30 and the battery module 40 can be disposed in different pillar structures 120, respectively, thereby enabling the electric camper 100 to maintain good balance.

[0064] Exemplarily, the first pillar and the second pillar can be the pillar structure 120 located in front of the vehicle body 10, or the pillar structure 120 located behind the vehicle body 10. Generally, in order to maintain the balance of the electric camper 100, the first pillar and the second pillar can be the pillar structure 120 located behind the vehicle body 10.

[0065] In some embodiments, the column structure 120 further includes a third column and a fourth column; wherein the wheels corresponding to the first column and the second column are motor wheels 21, and the wheels corresponding to the third column and the fourth column are universal wheels.

[0066] For example, in order to reduce the length of the connection line between the control module 30 and the motor wheel 21, the wheels corresponding to the first and second columns can be set as motor wheels 21, and the wheels corresponding to the third and fourth columns can be set as universal wheels.

[0067] To maintain the balance of the electric camper 100, the first and second pillars are typically located in the pillar structure 120 at the rear of the vehicle body 10, while the third and fourth pillars are located in the front of the vehicle body 10. Therefore, the wheels located at the rear of the vehicle body 10 are motor wheels 21, while the wheels located at the front of the vehicle body 10 are universal wheels. By placing the motor wheels 21 at the rear of the vehicle body 10, the electric camper 100 can be more effectively driven.

[0068] It should be noted that the corresponding arrangement of the column structure 120 and the motor wheel 21 can be set according to actual conditions and is not specifically limited here.

[0069] like Figure 5 and Figure 6 As shown, in some embodiments, the frame 12 further includes a folding assembly connected to a pillar structure 120. The pillar structure 120 and the folding assembly are used to support and secure the vehicle body 11. The pillar structure 120 further includes a third pillar and a fourth pillar. The first and second pillars are located behind the vehicle body 10, while the third and fourth pillars are located in front of the vehicle body 10. The front of the vehicle body 10 is in the direction of the pull rod assembly 50 of the electric camper 100. Thus, the folding assembly allows the frame 12 to be folded, enabling the electric camper 100 to be stored in four directions. This can minimize the size of the electric camper 100 and avoid the drawback of existing electric campers 100 that only have a two-way folding function, resulting in an excessively large storage size and inconvenient transportation and storage.

[0070] Specifically, the folding assembly includes two first folding assemblies 121, two second folding assemblies 122, and a third folding assembly 123. One of the first folding assemblies 121 is used to connect the first and second pillars, and the other first folding assembly 121 is used to connect the third and fourth pillars. One of the second folding assemblies 122 is used to connect the first and third pillars, and the other second folding assembly 122 is used to connect the second and fourth pillars. The third folding assembly 123 is provided at the bottom of the vehicle body 10 and is used to connect the first, second, third, and fourth pillars. The arrangement of the first folding assemblies 121, the second folding assemblies 122, and the third folding assemblies 123 enables the electric camper 100 to be stored in four directions, minimizing the size of the electric camper 100 and avoiding the drawback of existing electric campers 100 that only have a two-way folding function, resulting in an excessively large storage size that is inconvenient to transport and store.

[0071] For example, the first folding component 121 can be set at the front and rear of the car body 10, the second folding component 122 can be set on both sides of the car body 10, and the third folding component 123 can be set at the bottom of the car body 10. Of course, it can also be set according to actual conditions, and no specific limitation is made here.

[0072] like Figure 5 As shown, in some embodiments, the first folding component 121 includes two first links 1211, two second links 1212 and a rotating shaft 1213, the first end of the first link 1211 is rotatably connected to the lower end of the column structure 120, the second end of the first link 1211 is rotatably connected to the first end of the second link 1212, the second end of the second link 1212 is rotatably connected to the upper end of the column structure 120, and the two first links 1211 are also rotatably connected through the rotating shaft 1213; the battery module 40 and the control module 30 are electrically connected through a first connecting line, and the first connecting line is connected to the battery module 40 and the control module 30 via one of the first links 1211, the rotating shaft 1213 and the other first link 1211.

[0073] Specifically, the first end of one of the first links 1211 can be rotatably connected to the lower end of the first column, and the second end of the first link 1211 can be rotatably connected to the first end of one of the second links 1212, and the second end of the second link 1212 is rotatably connected to the upper end of the second column; the first end of the other first link 1211 can be rotatably connected to the lower end of the second column, and the second end of the first link 1211 is rotatably connected to the first end of the other second link 1212, and the second end of the second link 1212 is rotatably connected to the upper end of the first column; the middle parts of the two first links 1211 are also rotatably connected through the rotating shaft 1213, thereby forming a first folding component 121.

[0074] When the folding assembly switches from the unfolded state to the folded state, the second connecting rod 1212 will rotate upward relative to the column structure 120, and the second connecting rod 1212 and the first connecting rod 1211 connected thereto will also rotate. The two first connecting rods 1211 will also rotate relative to the rotating shaft 1213, thereby switching the electric camper 100 from the working state to the storage state.

[0075] It should be noted that the second folding component 122 and the third folding component 123 also achieve the folding function through the same or similar structure as the first folding component 121, and will not be repeated here.

[0076] If the battery module 40 is set in the first column, the control module 30 is set in the second column, and the first column and the second column are connected by the first folding component 121. The battery module 40 and the control module 30 are electrically connected through the first connecting line. The first connecting line can be connected to the battery module 40 and the control module 30 through the bottom of the first column, one of the first connecting rods 1211, the rotating shaft 1213, the other first connecting rod 1211 and the bottom of the second column, thereby achieving the connection line between the battery module 40 and the control module 30 completely set inside the frame 12, so that the connection line is completely hidden inside the frame 12 and will not be exposed to the air, thereby preventing the connection line from aging and enhancing the waterproofness, thereby improving the user experience.

[0077] It should be noted that the routing path of the first connecting line inside the frame 12 can be any path. For example, the first connecting line can also be connected to the battery module 40 and the control module 30 through the first column, one of the first connecting rods 1211, the rotating shaft 1213, the second connecting rod 1212 and the second column. The first connecting line can also be connected to the battery module 40 and the control module 30 through the second folding component 122 or the third folding component 123. No specific limitation is made here.

[0078] like Figure 7 and Figure 8 As shown, in some embodiments, the vehicle frame 12 further includes a column connector 125 and a first stopper 126. The column connector 125 is disposed at the upper end of the column structure 120 and includes a protrusion 1251. The first stopper 126 is sleeved on the second end of the second link 1212. The first stopper 126 and the protrusion 1251 cooperate to positionally engage with each other so that when the folding assembly is in the unfolded state, the second link 1212 is perpendicular to the column structure 120. This prevents the second link 1212 from tipping downward when the folding assembly is in the unfolded state, thereby preventing the folding assembly from properly unfolding or causing the folding assembly to collapse.

[0079] Exemplarily, the column connector 125 can be set at the upper end of the column structure 120, and the column connector 125 includes a protrusion 1251. The first limit member 126 is sleeved on the second end of the second link 1212 and the protrusion 1251, so that the first limit member 126 connects the column connector 125 and the second link 1212. The first limit member 126 also cooperates with the protrusion 1251 to limit the position in the wheel direction, thereby preventing the second link 1212 from rotating downward relative to the column structure 120, that is, preventing the second link 1212 from tilting downward, thereby causing the folding component to fail to unfold normally or the folding component to be in a collapsed state.

[0080] like Figure 9As shown, in some embodiments, the frame 12 also includes two column supports 127, a connecting assembly 128 and a pull rod assembly 50, the two column supports 127 are used to support the column structure 120 located at the front wheel; the connecting assembly 128 is connected to the two column supports 127; the pull rod assembly 50 is arranged on the connecting assembly 128, and the pull rod assembly 50 is rotatably connected to the connecting assembly 128.

[0081] Specifically, two column supports 127 are respectively arranged on the two front wheels, which can support the column structure 120 located on the front wheels. The connecting assembly 128 is used to connect the two column supports 127. The pull rod assembly 50 is arranged on the connecting assembly 128. The pull rod assembly 50 is rotatably connected to the connecting assembly 128. The user pulls the electric camper 100 forward through the pull rod assembly 50. The user can also use the pull rod assembly 50 to assist in driving the electric camper 100 to move.

[0082] like Figure 10 As shown, in some embodiments, the frame 12 also includes two rotating connectors 129, which are used to connect the connecting assembly 128; the rotating connector 129 includes a limiting portion 1291 and a connecting portion 1292, the limiting portion 1291 cooperates with the column support 127 to limit the position in the wheel direction, and is rotationally connected to the column support 127 in the front direction of the vehicle body 10; the connecting portion 1292 cooperates with the connecting assembly 128 to limit the position in the direction parallel to the front wheel, and is rotationally connected to the connecting assembly 128 in the wheel direction.

[0083] Specifically, the frame 12 further includes two rotating connectors 129, which are respectively used to connect the connecting assembly 128 and the column support 127. The rotating connectors 129 can cooperate with the column support 127 to limit the position in the direction of the wheels and are rotatably connected to the column support 127 in the direction forward of the vehicle body 10. The rotating connectors 129 can also cooperate with the connecting assembly 128 to limit the position in a direction parallel to the front wheels and are rotatably connected to the connecting assembly 128 in the direction of the wheels. This allows the pull rod assembly 50 to rotate forward and be stowed downward, making it easier for the user to pull and stow the electric camper 100.

[0084] Exemplarily, the rotating connecting member 129 includes a limiting portion 1291 and a connecting portion 1292. The limiting portion 1291 and the connecting portion 1292 can be connected at 90°. The limiting portion 1291 cooperates with the column support member 127 for limiting in the direction of the wheel, and is rotationally connected to the column support member 127 in the front direction of the vehicle body 10; the connecting portion 1292 cooperates with the connecting component 128 for limiting in the direction parallel to the front wheel, and is rotationally connected to the connecting component 128 in the direction of the wheel.

[0085] In some embodiments, the connecting assembly 128 also includes a second limit member 1283, a third link 1281 and a fourth link 1282, the second limit member 1283 is used to support the pull rod assembly 50; one end of the third link 1281 is connected to one of the column supports 127, and the other end of the third link 1281 is matched with the second limit member 1283 in the upper limit direction parallel to the front wheel, and is rotatably connected to the second limit member 1283 in the direction of the wheel; one end of the fourth link 1282 is connected to another column support 127, and the other end of the fourth link 1282 is matched with the second limit member 1283 in the upper limit direction parallel to the front wheel, and is rotatably connected to the second limit member 1283 in the direction of the wheel; wherein, the second limit member 1283 is also used to make the third link 1281 and the fourth link 1282 in a parallel state when the electric camper 100 is in working state.

[0086] Specifically, one end of the third link 1281 is limitedly connected to one of the column supports 127, the other end of the third link 1281 is matched with the second limit member 1283 for limit positioning in a direction parallel to the front wheel, and is rotationally connected to the second limit member 1283 in the direction of the wheel, one end of the fourth link 1282 is limitedly connected to another column support 127, the other end of the fourth link 1282 is matched with the second limit member 1283 for limit positioning in a direction parallel to the front wheel, and is rotationally connected to the second limit member 1283 in the direction of the wheel, that is, the third link 1281 and the fourth link 1282 can rotate downward relative to the column support 127, but cannot rotate forward and backward.

[0087] For example, the second stopper 1283 can be mounted on the other end of the third link 1281 and the other end of the fourth link 1282. Due to the position-limiting connection between the third link 1281 and the fourth link 1282 and the column support 127, the third link 1281 and the fourth link 1282 can only rotate upward or downward in the direction of the wheel. Due to the provision of the second stopper 1283, the third link 1281 and the fourth link 1282 can only rotate downward in the direction of the wheel, and when the third link 1281 and the fourth link 1282 are parallel, the third link 1281 and the fourth link 1282 are restricted from further upward rotation. In this way, when the electric camper 100 is in operation, the third link 1281 and the fourth link 1282 are parallel, allowing the user to easily push the electric camper 100 via the pull rod assembly 50. When the electric camper 100 is in the storage state, the pull rod assembly 50 can be stowed downward, thereby saving space.

[0088] like Figure 11 and Figure 12As shown, in some embodiments, the pull rod assembly 50 includes a support rod 51 and a handle member 52, and the support rod 51 is set on the connecting assembly 128; the handle member 52 is sleeved on the support rod 51, and the handle member 52 is provided with a hollow portion 521, and the hollow portion 521 includes a handle portion 5211 and a clamping portion 5212. The handle portion is used to cooperate with external force to pull the electric camper 100, and the clamping portion 5212 is used to place the remote control 53 of the electric camper 100.

[0089] Specifically, the support rod 51 can be mounted on the second stopper 1283; the handle 52 is sleeved on the upper portion of the support rod 51. The handle 52 has a hollow portion 521, which includes a handle portion and a locking portion 5212. The handle portion is used to pull the electric camper 100 with an external force. The locking portion 5212 is shaped to match the shape of the remote control 53 of the electric camper 100, thereby accommodating the remote control 53 of the electric camper 100. This avoids the situation in which the user cannot find the remote control 53 due to the lack of a specific location for the remote control 53 in existing camper vehicles.

[0090] It should be noted that the engaging portion 5212 can also be used to place devices such as camping lights, chargers or mobile phones. It is only necessary to set the shape of the engaging portion 5212 to correspond to the shape of the device to be placed.

[0091] like Figure 12 As shown, in some embodiments, the inner wall of the engaging portion 5212 is further provided with a fixing groove 522, and the remote control 53 is engaged with the engaging portion 5212 through the fixing groove 522. In this way, the remote control 53 can be fixed to the engaging portion 5212, preventing the remote control 53 from falling off and being lost during the movement of the electric camper 100.

[0092] For example, fixing grooves 522 may be provided on the inner walls of both sides of the engaging portion 5212. The fixing grooves 522 are configured to engage with both sides of the remote control 53, thereby engaging the remote control 53 on the engaging portion 5212. This secures the remote control 53 to the engaging portion 5212, preventing the remote control 53 from falling off and being lost during movement of the electric camper 100.

[0093] In some embodiments, the support rod 51 is detachably connected to the handle 52 , thereby making it easier for the user to replace the handle 52 .

[0094] For example, the electric camper 100 provided in the embodiment of the present application may include a remote-controlled electric camper 100 or a pull-rod-controlled electric camper 100. Since the handle 52 is mounted on the support rod 51, the control mode of the electric camper 100 can be changed by replacing the handle 52, thereby realizing multi-control mode driving of the electric camper 100.

[0095] like Figure 13 As shown, in some embodiments, the support rod 51 further includes a latch 511 disposed on a side of the support rod 51 close to the vehicle frame 12. The latch 511 is configured to engage with the vehicle frame 12 to secure the rod assembly 50 to the vehicle frame 12. This prevents the rod assembly 50 from collapsing due to inertia when the remote-controlled electric camper 100 is in motion, thereby preventing the normal operation of the electric camper 100 from being affected.

[0096] For example, a latch is provided on the inner side of the support rod 51 and can engage with a recess provided on the rotating shaft 1213 to secure the rod assembly 50 to the vehicle frame 12, thereby maintaining the rod assembly 50 and the connecting assembly 128 in a vertical position. This prevents the rod assembly 50 from collapsing downward due to inertia when the remote-controlled electric camper 100 is in motion, thereby affecting the normal operation of the electric camper 100.

[0097] like Figure 14 and Figure 15 As shown, in some embodiments, the motor wheel 21 includes a wheel body 211, a motor and a rotating shaft 212, and the motor is used to drive the wheel body 211 to rotate relative to the rotating shaft 212; the wheel module 20 also includes a wheel fixing member 22, the wheel fixing member 22 is connected to the column structure 120, and is used to support the column structure 120, and the wheel fixing member 22 is also connected to the rotating shaft 212; the motor and the control module 30 are electrically connected through a second connecting line, and the second connecting line is connected to the motor and the control module 30 through the column structure 120, the wheel fixing member 22 and the rotating shaft 212, and the second connecting line is arranged in the column structure 120, the wheel fixing member 22 and the rotating shaft 212.

[0098] Specifically, one end of the wheel fixing member 22 can be connected to the column structure 120 and support the column structure 120, and the other end can be connected to the rotating shaft 212 to fix the motor wheel 21. A sealed cavity is also formed in the wheel fixing member 22 for placing the second connecting line.

[0099] The control module 30 is electrically connected to the motor via a second connecting line, so that the control module 30 controls the motor to drive the motor wheel 21. The second connecting line can be connected to the motor and the control module 30 via the column structure 120, the wheel fixing member 22, and the rotating shaft 212. The second connecting line is disposed within the column structure 120, the wheel fixing member 22, and the rotating shaft 212. This ensures that the connecting line between the control module 30 and the motor is completely disposed within the frame 12 and the wheel module 20. The connecting line is completely hidden within the frame 12 and the wheel module 20 and is not exposed to the air, thereby preventing the connecting line from aging and enhancing the waterproof performance, thereby improving the user experience.

[0100] It should be noted that the routing path of the second connecting line inside the frame 12 can be any path. For example, the second connecting line can also be connected to the control module 30 and the motor through the first column, one of the first connecting rods 1211, the rotating shaft 1213, the second connecting rod 1212 and the second column, the wheel fixing member 22 and the rotating shaft 212. The second connecting line can also be connected to the control module 30 and the motor through the second folding component 122 or the third folding component 123. No specific limitation is made here.

[0101] In the prior art, due to the fact that the control module 30 of the electric camper 100 is located outside the frame 12, the connecting wires between the control module 30 and the motor wheel 21 are inevitably exposed to the air. This exposure to the air accelerates the aging of the connecting wires. In addition, in a humid environment, water can easily flow along the connecting wires into the motor wheel 21, thereby damaging the motor wheel 21. However, the electric camper 100 of the present embodiment, through the sealed connection arrangement of the column structure 120, the wheel fixing member 22, and the rotating shaft 212, can completely conceal the connecting wires between the control module 30 and the motor within the frame 12 and the wheel module 20. The connecting wires are not exposed to the air, thereby preventing the connecting wires from aging and enhancing the waterproof performance, thereby improving the user experience.

[0102] In some embodiments, the wheel fixing member 22 includes a first load-bearing shell 221 and a second load-bearing shell 222. The first load-bearing shell 221 is connected to the column structure 120 and is used to support the column structure 120; the second load-bearing shell 222 is used to seal with the first load-bearing shell 221 to form a sealed cavity, so that the second connecting line is set in the sealed cavity; wherein the rotating shaft 212 is fixedly connected to the first load-bearing shell 221 and the second load-bearing shell 222.

[0103] Specifically, the first load-bearing shell 221 can be an outer shell, used to connect with the column structure 120 and support the column structure 120; the second load-bearing shell 222 can be an inner shell, and the shape of the second load-bearing shell 222 is adapted to the shape of the first load-bearing shell 221, so that the second load-bearing shell 222 can be sealed with the first load-bearing shell 221 to form a sealed cavity, and the second connecting line can be set in the sealed cavity; wherein, the rotating shaft 212 is fixedly connected to the first load-bearing shell 221 and the second load-bearing shell 222, so that the connecting line is completely hidden in the sealed cavity, and the connecting line will not be exposed to the air, thereby preventing the connecting line from aging and enhancing the waterproofness, thereby improving the user experience.

[0104] In some embodiments, the first load-bearing shell 221 is provided with a first connection hole, the second load-bearing shell 222 is provided with a second connection hole, and the rotating shaft 212 is passed through the first connection hole and the second connection hole and is limitedly engaged with the wheel fixing member 22.

[0105] Illustratively, the first connection hole can be arranged corresponding to the second connection hole, so that the rotating shaft 212 passes through the first connection hole and the second connection hole and is limitedly matched with the wheel fixing member 22, so that the motor wheel 21 is fixedly mounted on the wheel fixing member 22.

[0106] In some embodiments, the wheel fixing member 22 further includes a fixing member 223 , and the fixing member 223 is configured to engage with the rotating shaft 212 in a limiting manner so that the motor wheel 21 is fixedly connected to the wheel fixing member 22 .

[0107] Exemplarily, the fixing member 223 is used to fix the rotating shaft 212 on the first connecting hole and the second connecting hole, so that the rotating shaft 212 passes through the first connecting hole and the second connecting hole and is limitedly matched with the wheel fixing member 22, so that the motor wheel 21 is fixedly mounted on the wheel fixing member 22.

[0108] In some embodiments, a reflective member 224 is provided on the surface of the fixing member 223 , and the reflective member 224 is used to cover the first connection hole and reflect light.

[0109] The reflective element 224 can be made of waterproof material and reflective material.

[0110] For example, a reflector 224 is provided on the surface of the fixing member 223 (i.e., the outer surface of the wheel fixing member 22). Since the reflector 224 is made of waterproof material, it can prevent rainwater from entering the motor through the screw hole. In addition, the reflector 224 can also cover the first connection hole, thereby achieving the effect of shielding the first connection hole, making the electric camper 100 more aesthetically pleasing. Because the reflector 224 is made of reflective material, it can produce a reflective effect when exposed to headlights at night, ensuring the safety of the electric camper 100.

[0111] In some embodiments, a limiting protrusion 2211 is formed on the surface of the wheel fixing member 22 , and the limiting protrusion 2211 is used to cooperate with the pillar structure 120 in a limiting manner.

[0112] Illustratively, the limiting protrusion 2211 is used for limiting the position of the pillar structure 120 , so that the pillar structure 120 can be stably disposed above the wheel fixing member 22 .

[0113] In some embodiments, the limiting protrusion 2211 includes a wiring hole 2212 , and the second connecting wire passes through the wiring hole 2212 and is arranged in the column structure 120 and the wheel fixing component 22 .

[0114] For example, the second connecting line can be passed through the wiring hole 2212 and the column structure 120 and the wheel fixing part 22, so as to connect the control module 30 and the motor, and the connecting line between the control module 30 and the motor can be completely hidden inside the frame 12 and the wheel module 20. The connecting line will not be exposed to the air, thereby preventing the connecting line from aging and enhancing the waterproofness, thereby improving the user experience.

[0115] like Figure 16 and Figure 17 As shown, in some embodiments, the control module 30 includes a first shell 31 and a control board 32. The first shell 31 is adapted to the shape of the column structure 120 so that the control module 30 can be installed in the column structure 120. A groove 310 is formed at one end of the first shell 31. The shape of the groove 310 is adapted to the shape of the functional module 60 and is used to place the functional module 60. The other end of the first shell 31 is connected to the column structure 120; the control board 32 is arranged in the first shell 31 and is connected to the functional module 60. The control board 32 is used to control the battery module 40 to supply power to the functional module 60.

[0116] Exemplarily, the control board 32 may be any circuit board or chip with a control function.

[0117] Specifically, a groove 310 is formed at one end of the first shell 31. The shape of the groove 310 is adapted to the shape of the functional module 60 and is used to place the functional module 60, so that the functional module 60 can be integrated into the column structure 120. At the same time, the control board 32 is arranged in the first shell 31 and connected to the functional module 60. The control board 32 can control the battery module 40 to power the functional module 60, ensuring that the functional module 60 can be used in any scenario.

[0118] For example, the functional module 60 may include a lighting module 70, an automatic tracking module, a display module, a player module, a GPS module, or a mosquito repellent module. The lighting module 70 may be a camping light or an ambient light, and the player module may be an audio player or a video player. Any functional module 60 may be used, and the shape and size of the recess 310 may be designed based on the shape of the functional module 60. No specific limitations are set herein.

[0119] The automatic following module enables the electric camper to automatically follow the user's movements. Specifically, since the remote control is the transmitter and the automatic following module is the receiver, the user can simply hold the remote control and the electric camper can automatically follow the user without having to operate it. The display module can be a display screen, for example, for displaying playback images; the GPS module can be a satellite positioning module for locating the electric camper.

[0120] In some embodiments, the electric camper 100 further includes a telescopic assembly 33, which is disposed in the first shell 31. One end of the telescopic assembly 33 is detachably connected to the functional module 60, and the other end of the telescopic assembly 33 is fixedly connected to the column structure 120. The telescopic assembly 33 is used to raise or lower the functional module 60.

[0121] Specifically, the telescopic component 33 is arranged in the first shell 31, one end of the telescopic component 33 is used to support the functional module 60 and is detachably connected to the functional module 60, so that the functional module 60 can be removed and used separately, and the other end of the telescopic component 33 is fixedly connected to the column structure 120. The telescopic component 33 is used to raise or lower the functional module 60.

[0122] For example, when the user needs to provide high-altitude lighting, the light-emitting module 70 can be raised by the telescopic component 33, and then the light-emitting module 70 can be controlled to emit light to achieve the effect of high-altitude lighting; after the user has used the light-emitting module 70, the light-emitting module 70 can be lowered by the telescopic component 33 to store the light-emitting module 70 in the groove 310; when the user needs to provide mobile lighting, the light-emitting module 70 can be removed and used alone to achieve the effect of mobile lighting.

[0123] like Figure 16 As shown, in some embodiments, the telescopic assembly 33 further includes a rotating member 330 , which is disposed at one end of the telescopic assembly 33 . The rotating member 330 is used to connect the functional module 60 so that the functional module 60 can rotate relative to the telescopic assembly 33 .

[0124] Exemplarily, the rotating member 330 is arranged at one end of the telescopic component 33, and the rotating member 330 is used to be rotatably connected to the bottom of the functional module 60. When the user rotates the functional module 60, the rotating member 330 can rotate with the functional module 60 so that the functional module 60 can rotate relative to the telescopic component 33.

[0125] like Figure 18 As shown, in some embodiments, the functional module 60 includes a light-emitting module 70, which includes a lamp housing 71, a light-emitting control board 72 and a power supply battery 73. The lamp housing 71 is adapted to the shape of the column structure 120 so that the camping lamp can be installed in the column structure 120; the light-emitting control board 72 is arranged in the lamp housing 71, and the light-emitting control board 72 includes at least one light-emitting component 721, which is used to irradiate light; the power supply battery 73 is arranged in the lamp housing 71, and the power supply battery 73 is electrically connected to the light-emitting control board 72, and the power supply battery 73 is used to power the light-emitting component 721.

[0126] Specifically, the shape of the lamp housing 71 is adapted to the groove 310 formed in the first housing 31, so that the camping lamp can be installed in the groove 310. The light-emitting elements 721 can be arranged on the light-emitting control board 72. The power supply battery 73 is electrically connected to the light-emitting control board 72 and is used to power the light-emitting elements 721 so that they can emit light.

[0127] When the light emitting module 70 is required to emit light, the light emitting control board 72 can control the power supply battery 73 to supply power to the light emitting element 721 and control the light emitting element 721 to emit light to achieve a lighting effect.

[0128] Exemplarily, the light control board 72 may be any circuit board or chip with a control function.

[0129] During outdoor activities at night, lighting equipment is often needed to illuminate the dark environment. In order to meet the lighting needs at night, users often have to carry additional lighting equipment for lighting. In order to meet the lighting needs for a long time, users often need to carry additional charging equipment to charge the lighting equipment, which makes the user carry heavy items and has a poor camping experience. The electric camper 100 provided in the embodiment of the present application integrates the light-emitting module 70 in the column structure 120. The light-emitting module 70 can be stored in the column structure 120, and the user does not need to carry it separately. At the same time, the light-emitting module 70 can not only be set on the camper frame 12 for lighting, but can also be disassembled from the column structure 120 and used separately, thereby meeting the needs of mobile lighting scenes. In addition, the light-emitting module 70 can also be charged by the built-in battery module 40 of the electric camper 100, thereby solving the problem of the difficulty of charging the outdoor light-emitting module 70.

[0130] For example, when the user needs to use the light-emitting module 70, the user can remove it from the column structure 120 for use; when the user needs to store the light-emitting module 70, the user stores the light-emitting module 70 into the column structure 120; when the user needs to charge the light-emitting module 70, the user can control the battery module 40 through the control module 30 to charge the light-emitting module 70.

[0131] like Figure 18 As shown, in some embodiments, the lamp housing 71 includes a second housing 711 and a third housing 712, the second housing 711 is connected to the column structure 120, the second housing 711 includes a light-emitting portion 7111, the light-emitting portion 7111 is arranged corresponding to the light-emitting component 721, and the light-emitting portion 7111 is used to transmit light emitted by the light-emitting component 721; the third housing 712 is used to seal with the second housing 711 to form a accommodating cavity, so that the light-emitting control board 72 and the power supply battery 73 are arranged in the accommodating cavity.

[0132] It should be noted that the light-emitting portion 7111 can be set at the bottom of the second shell 711 (i.e., the part that fits with the groove 310), or can be set on the side of the second shell 711, or can be set on the bottom and side of the second shell 711 at the same time, or can be set on the third shell 712, and no specific limitation is made here.

[0133] Exemplarily, the shape of the third shell 712 is adapted to the shape of the second shell 711 so that the third shell 712 and the second shell 711 are sealed together to form a receiving cavity, and the light control board 72 and the power supply battery 73 are sealed in the receiving cavity.

[0134] Specifically, the third housing 712 is further provided with a light-emitting charging interface 7121, which is used to connect to an external power source so that the external power source can charge the power supply battery 73. This can prevent the power supply battery 73 from being charged when the battery module 40 is out of power, thereby ensuring the normal use of the light-emitting module 70.

[0135] In some embodiments, a charging contact terminal is provided in the lamp housing 71, and the charging contact terminal is electrically connected to the light-emitting control board 72; wherein, when the light-emitting module 70 is connected to the column structure 120, the charging contact terminal is also in contact with and connected to the power supply contact terminal provided in the first housing 31, so that the battery module 40 charges the power supply battery 73.

[0136] Specifically, when the light-emitting module 70 is placed in the column structure 120, the charging contact terminal is also connected to the power supply contact terminal set in the first shell 31, and the control board 32 can control the battery module 40 to charge the power supply battery 73 through the power supply contact terminal and the charging contact terminal.
