[0029] See also Figure 1 and Figure 2 , the present application provides a ladder 100, Figure 1 It is a schematic diagram of a partial area of ​​a ladder. The ladder 100 includes two handrails 30 spaced apart from each other and a pedal assembly 10. The pedal assembly 10 is connected between the two handrails 30. The pedal assembly 10 includes a treading module 11 and a heating module 12 that are connected to each other. At least one of the treading module 11 and the heating module 12 is connected to the handrail 30. The heating module 12 includes a heating element 121. The treading module 11 and the heating module 12 can switch between a folded state and an unfolded state. In the folded state, the treading module 11 and the heating module 12 at least partially overlap and block the heating element 121; in the unfolded state, the heating element 121 does not overlap with the treading module 11.

[0030] The heating element 121 can be used as a heat source. In the folded state, the pedal module 11 can be stepped on by the user to climb, and the pedal module 11 blocks the heating element 121. On the one hand, it can prevent the heating element 121 from being damaged by being stepped on directly. On the other hand, it can protect the heating element 121 from damage such as collision, scratching, and liquid corrosion. On another hand, it can prevent the residual heat of the heating element 121 from scalding the user. In the unfolded state, the heating element 121 does not overlap with the pedal module 11, that is, the heating element 121 is not blocked by the pedal module 11, so that the user can use the heating element 121 for heating. In this way, the ladder 100 can provide not only climbing for the user, but also a heating function, so that the user does not need to carry additional heat source equipment to save storage space.

[0031] In summary, the step assembly 10 of the ladder 100 of the present embodiment can be folded for climbing by the user, and unfolded to expose the heating element 121 for heating, allowing the ladder 100 to also provide a heating function. This eliminates the need for users to carry additional heat source equipment, reducing storage space required for outdoor travel.

[0032] See also Figure 1 and Figure 2 In some embodiments, the ladder 100 further includes a plurality of treads 50 , each tread 50 being connected between two handrails 30 , and the treads 50 can be stepped on by a user to climb the ladder 100 .

[0033] In some embodiments, the tread 50 and the step assembly 10 are detachably connected to the handrail 30. This allows the tread 50 and step assembly 10 to be removed from the handrail 30 for easier storage when the ladder 100 is stored. The tread 50 and step assembly 10 can be installed in any order to the handrail 30, allowing the step assembly 10 to be positioned at a height suitable for user operation. For example, the step assembly 10 can be installed on the last step, the second-to-last step, and so on.

[0034] Furthermore, in some embodiments, the armrest 30 , after being separated from the tread member 50 and the pedal assembly 10 , is retractable or foldable to further reduce storage space occupation.

[0035] See also Figure 1 In some embodiments, the heating module 12 further includes a base 123, which is connected to the armrest 30, and the heating element 121 is installed on the base 123. The pedal assembly 10 further includes a flip shaft 13, which is rotatably installed on the base 123. The pedal module 11 is connected to the flip shaft 13, and the pedal module 11 can rotate around the flip shaft 13 to switch between a folded state and an unfolded state.

[0036] like Figure 1As shown, Figure 1 The diagram illustrates the position of the pedal module 11 in the unfolded state. In the folded state, the pedal module 11 can be placed over the base 123. The user steps on the pedal module 11 while climbing. To use the heating element 121, the user can flip the pedal module 11 around the flip axis 13 to expose the heating element 121 located on the base 123.

[0037] In some embodiments, the base 123 includes a first surface 1231. In the folded state, the pedal module 11 covers the first surface 1231 and shields the heating element 121. In the unfolded state, the pedal module 11 is opened relative to the first surface 1231 to expose the heating element 121.

[0038] In some embodiments, the base 123 includes a first coupling portion 124, and the treadle module 11 includes a second coupling portion 111. In the folded state, the first coupling portion 124 couples with the second coupling portion 111 to restrict the treadle module 11 from flipping relative to the base 123. For example, the first coupling portion 124 and the second coupling portion 111 may be a snap-fit ​​connection structure, a mortise and tenon connection structure, a magnetic connection structure, etc., which are not limited here.

[0039] In some embodiments, the pedal assembly 10 further includes an elastic member (not shown), which is sleeved on the flip shaft 13 and respectively connected to the base 123 and the pedal module 11. The pre-tightening force provided by the elastic member can keep the pedal module 11 in an unfolded state relative to the first surface 1231. In this way, when the heating element 121 is used, there is no need to support the pedal module 11 to prevent it from falling. In the folded state, the first coupling portion 124 is combined with the second coupling portion 111 to prevent the pre-tightening force provided by the elastic member from driving the pedal module 11 to flip relative to the base 123, so that the pedal module 11 can cover the first surface 1231 of the base 123. Among them, the elastic member can be a torsion spring, a tension spring, etc., which is not limited here.

[0040] See also Figure 3 In some embodiments, the pedal assembly 10 further includes a support rod 14 rotatably mounted on the base 123. In the folded state, the support rod 14 is horizontally positioned relative to the first surface 1231. In the unfolded state, the support rod 14 can be manually rotated to a position upright relative to the first surface 1231 to support the pedal module 11 and prevent it from falling.

[0041] See also Figure 4 In some embodiments, the pedal module 11 includes a first side 112 and a second side 113 that are opposite to each other. The first side 112 of the pedal module 11 is for the user to step on, and the first side 112 of the pedal module 11 is provided with anti-slip grooves (not shown). The anti-slip grooves are used to increase friction and prevent the user from slipping when climbing.

[0042] In some embodiments, the second side 113 of the tread module 11 is provided with an escape cavity 114. In the folded state, the heating element 121 is accommodated in the escape cavity 114 and is spaced apart from the inner wall of the tread module 11. In this way, when the tread module 11 is stepped on, the heating element 121 is not subjected to pressure, thereby preventing the heating element 121 from being damaged by pressure.

[0043] Furthermore, in one embodiment, the second side 113 of the pedal module 11 is provided with an avoidance cavity 114, and the heating element 121 protrudes relative to the first surface 1231. This facilitates the dispersal of heat from the heating element 121. For example, the heating element 121 includes a heating lamp that provides illumination and heat. The heating lamp protrudes relative to the first surface 1231, allowing the light and heat from the heating lamp to diffuse in all directions when deployed.

[0044] See also Figure 1 In some embodiments, the first surface 1231 is provided with a recess 115, and the heating element 121 is disposed within the recess 115. When the treadle module 11 covers the first surface 1231, the heating element 121 is spaced apart from the treadle module 11. This, on the one hand, prevents the heating element 121 from being damaged by pressure when the treadle module 11 covers the first surface 1231. On the other hand, in the unfolded state, the recess 115 can be used to place cooking utensils, ensuring that the cooking utensils are stably placed above the heating element.

[0045] See also Figure 4 In some embodiments, the heating element 121 includes a heating element 1213, and the heating element 1213 is exposed from the first surface 1231. In one embodiment, the heating element 1213 can be a gas stove, a kerosene lamp, an infrared heating lamp, etc., which are not limited here.

[0046] In one embodiment, the device that supplies energy to the heating element 1213 is housed in a housing space inside the base 123. For example, in the case where the heating element 1213 is a gas stove, the housing space inside the base 123 houses a gas tank, a pipe and a valve, the pipe connects the gas tank and the gas stove, the valve is installed on the pipe, and the user can operate the valve to control the amount of gas released. Similarly, in the case where the heating element 1213 is a kerosene lamp, the housing space inside the base 123 houses an oil storage tank, and the oil storage tank is connected to the kerosene lamp for storing kerosene. Similarly, in the case where the heating element 1213 is an infrared heating lamp, the housing space inside the base 123 houses a power supply, and the power supply is electrically connected to the infrared heating lamp for supplying power to the infrared heating lamp.

[0047] In another embodiment, the device that powers the heating element 1213 can also be housed in the internal storage space of the armrest 30, which is not limited here. For example, if the heating element 1213 is a gas stove, the storage space in the armrest 30 houses the gas tank, and the storage space in the base 123 houses the pipe, valve, and heating element 1213. One end of the pipe extends into the storage space in the armrest 30 and communicates with the gas tank, and the other end of the pipe communicates with the gas stove.

[0048] See also Figure 5 In some embodiments, the heating element 121 includes a heated plate 1215 and a heating element 1213. The heated plate 1215 is exposed from the first surface 1231. The heating element 1213 is housed in the base 123 and is used to heat the heated plate 1215. In other words, the heat emitted by the heating element 1213 can be transferred to the heated plate 1215, and the heat is transmitted through the heated plate 1215. In this way, the heating element 1213 does not directly contact the object to be heated, and heating the object to be heated using the heated plate 1215 can achieve more uniform heating.

[0049] In one embodiment, heating element 1213 is a coil, and heated plate 1215 can be a heat-resistant plate such as a ceramic plate or a black crystal plate. Heated plate 1215 is used to support the cookware. The housing within base 123 also houses a power supply electrically connected to the coil. When the power supply provides power to the coil, the coil generates an alternating magnetic field, causing the cookware placed on heated plate 1215 to generate a large number of dense eddy currents. This induced current is converted into heat, heating the food within the cookware. In other words, heating element 121 can be used as an induction cooker to heat food.

[0050] In another embodiment, heating element 1213 is a resistance wire, and heated plate 1215 can be a heat-conducting plate such as a metal plate or alloy plate. Heated plate 1215 is used to hold food. The housing space within base 123 also houses a power supply electrically connected to the resistance wire. When the power supply provides power to the resistance wire, the resistance wire generates heat, which is then transferred to heated plate 1215, raising its temperature and thereby heating the food held thereon. In other words, heating element 121 can function as an electric grill for heating food.

[0051] See also Figure 5 In some embodiments, the base 123 is provided with a heat dissipation port 1233 , which is used for ventilation of the receiving space within the base 123 , thereby facilitating heat dissipation of the base 123 .

[0052] In some embodiments, the receiving space within the base 123 further accommodates a fan (not shown), which is used to promote gas flow in the receiving space within the base 123 to help dissipate heat.

[0053] See also Figure 6 and Figure 7 In some embodiments, the pedal module 11 is connected to the armrest 30, the pedal assembly 10 further includes a rotating shaft 17, and the rotating shaft 17 is rotatably mounted on the pedal module 11. The heating module 12 further includes a connecting member 128, which connects the heating element 121 and the rotating shaft 17. The connecting member 128 can drive the heating element 121 to rotate around the rotating shaft 17 to switch between a folded state and an unfolded state.

[0054] The pedal module 11 is connected to the armrest 30, and the pedal module 11 is fixed relative to the armrest 30, so that the pressure of the pedal is mainly applied to the pedal module 11, which can prevent the heating module 12 from being damaged by pressure. In addition, the heating module 12 does not need to be connected to the two armrests 30, which can reduce the size of the heating module 12.

[0055] In the folded state, the heating module 12 is located below the pedal module 11, and the heating element 121 overlaps the pedal module 11. In the unfolded state, the heating element 121 does not overlap the pedal module 11, that is, the heating element 121 extends relative to the pedal module 11. This prevents the pedal module 11 from blocking the heating element 121, making heating more convenient.

[0056] In some embodiments, the pedal module 11 includes a first side 112 and a second side 113 that are opposite to each other. The first side 112 is for a user to step on, and the second side 113 has a receiving slot 118. In the folded state, the heating element 121 is located within the receiving slot 118. In the unfolded state, the heating element 121 extends out of the receiving slot 118. Thus, in the folded state, the receiving slot 118 can prevent the heating element 121 from being accidentally touched and rotating to a position extending relative to the pedal module 11, thereby providing protection.

[0057] In some embodiments, the heating element 121 includes an igniter, which is used to generate sparks or electric arcs for ignition. In one embodiment, the heating element 121 includes a spark igniter, the storage space in the armrest 30 stores a gas tank, and the storage space in the connector 128 stores a pipe, which connects the spark igniter and the gas tank respectively. The spark igniter can generate sparks. When the gas tank provides gas to the spark igniter, the gas is ignited by the spark and emits a flame, so that the heating element 121 can be used to heat items. In another embodiment, the heating element 121 includes an arc igniter, and the storage space in the connector 128 stores a power supply electrically connected to the arc igniter. When the power supply supplies power to the arc igniter, the arc igniter can generate a continuous arc, and the arc can be used to heat items.

[0058] See also Figure 2The present application also provides a rooftop tent 1000, comprising a mounting base 200, a tent body 300, and the ladder 100 of any of the above embodiments. The mounting base 200 is used to connect to the vehicle body, the tent body 300 is mounted on the mounting base 200, and the ladder 100 is connected to the mounting base 200.

[0059] In some embodiments, the ladder 100 is detachably connected to the mounting base 200. In this way, the ladder 100 can be stored separately during transportation, which is convenient for flexible transportation.

[0060] In some embodiments, the ladder 100 is reversible relative to the mounting base 200. During transportation, the ladder 100 can be flipped over the mounting base 200 to prevent the ladder 100 from extending outside the vehicle roof. When setting up the tent body 300, the ladder 100 can be flipped outward from the mounting base 200 to facilitate climbing.

[0061] In the rooftop tent 1000 of the present application, the step assembly 10 of the ladder 100 can be folded for the user to climb, and can be unfolded to expose the heating element 121 for heating, allowing the ladder 100 to also provide a heating function. This eliminates the need for users to carry additional heating equipment, reducing storage space required for outdoor travel.
