Description

Technical Field

[0001] This invention relates to a trunk pedal structure for automobiles, and more particularly to a trunk pedal device and a vehicle. Background Technology

[0002] With the development of living standards and the economy, more and more people own cars, making travel more time-saving, labor-saving, convenient, and comfortable. People no longer need to worry about queuing for buses or carrying too much luggage. Luggage is usually placed in the trunk. However, when placing heavy items like suitcases in the trunk, it requires lifting the items to the trunk's height before putting them in. This process requires considerable physical effort, especially for those with less strength, making it inconvenient to load heavy items into the trunk. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a trunk pedal device and vehicle, which solves the problem of laborious and inconvenient loading and unloading of items such as suitcases into the trunk, and improves the convenience of loading items into the trunk.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A trunk step device includes a fixed frame, a reel assembly, a telescopic device, and a take-up belt. The reel assembly is mounted on the fixed frame, and the take-up belt is wound around the reel assembly. The telescopic device includes a telescopic motor and a telescopic rod. The telescopic rod includes at least two slidably connected initial and final sliding sections. The telescopic motor is connected to the telescopic rod to drive it to extend or retract. The telescopic device is connected to a rotary motor, which drives the telescopic device to rotate by a set angle, causing the telescopic rod to tilt downwards. The take-up belt is connected to the telescopic rod. The take-up belt is released as the telescopic rod extends to form a flat step for carrying items, and it is wound up as the telescopic rod retracts.

[0006] In one embodiment, the reel device includes a drive motor, a drum, and a reel rod. The output end of the drive motor is connected to the reel rod, and the drum is sleeved on the reel rod. The initial section of the take-up tape is fixedly connected to the drum, the take-up tape is wound around the drum, and the final section of the take-up tape is fixedly connected to the telescopic rod.

[0007] In one embodiment, the number of telescopic devices is at least two, respectively disposed at both ends of the reel device, and the two sides of the take-up tape are connected to the adjacent telescopic rods.

[0008] In one embodiment, each slide bar of the telescopic rod has a groove along its length on the side near the take-up tape, and a connecting block is fixed to the inner wall of the last slide bar of the telescopic rod at the groove. The side of the last section of the take-up tape is connected to the last slide bar through the connecting block.

[0009] In one embodiment, the end of the final slide bar is provided with a grounding stabilizing device. When the telescopic rod extends to the point where the final slide bar contacts the ground, the grounding stabilizing device pops out and contacts the ground.

[0010] In one embodiment, the grounding stabilization device includes a pressure sensor, a stabilizing rod, and a rotation limiting mechanism. The stabilizing rod is connected to the end of the final slide rod through the rotation limiting mechanism, and the pressure sensor is disposed on the rotation limiting mechanism.

[0011] In one embodiment, the rotating motor is mounted on the fixed frame, and the output end of the rotating motor is connected to the telescopic motor.

[0012] In one embodiment, the trunk pedal device further includes a slide rail for installation inside the trunk. The slide rail is located below the telescopic rod, and the tilt angle of the slide rail is the same as the tilt angle of the telescopic rod after rotation.

[0013] In one embodiment, the end of the final slide bar is provided with a grounding stabilizing device, and the trunk pedal device further includes a controller, which is electrically connected to the reel device, the telescopic device, the rotating motor and the grounding stabilizing device.

[0014] The present invention also provides a vehicle including a trunk step device as described above, the trunk step device being installed inside the trunk of the vehicle.

[0015] The beneficial effects of this invention are as follows: By installing the trunk pedal device in the trunk of a vehicle, a telescopic motor drives the telescopic rod to extend, and a reel device drives the winding belt to release as the telescopic rod extends, forming a flat pedal. A rotating motor drives the telescopic device to rotate at an angle so that the end slide rod abuts the ground. The items to be transported are placed on the flat pedal and slide into the trunk. The sliding friction between the items and the flat pedal replaces the direct lifting of the items, reducing labor intensity, saving physical strength, and facilitating personnel operation.

[0028] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0029] This invention provides a trunk pedal device, such as... Figure 1 and Figure 2 As shown, the device includes a fixed frame 1, a reel assembly 2, a telescopic device 3, and a take-up belt 4. The reel assembly 2 is mounted on the fixed frame 1, and the take-up belt 4 is wound around the reel assembly 2. The reel assembly 2 is used to drive the take-up belt 4 to release or retract. The telescopic device 3 includes a telescopic motor 31 and a telescopic rod 32. The telescopic rod 32 includes at least two slidably connected sections: an initial slide rod 321 and an end slide rod 322. Multiple interconnected intermediate slide rods 325 can also be provided between the initial slide rod 321 and the end slide rod 322. The telescopic motor 31 is connected to the telescopic rod 32 to drive the telescopic rod 32 to extend or retract. The telescopic device 3 is connected to a rotary motor 5, which drives the telescopic device 3 to rotate by a set angle, causing the telescopic rod 32 to tilt downwards. The take-up belt 4 is connected to the telescopic rod 32.

[0030] In this embodiment, as Figure 1 and Figure 6 As shown, when the telescopic rod 32 extends, the winding belt 4 is released along with the extension of the telescopic rod 32 to form a flat pedal. Driven by the rotating motor 5, the telescopic rod 32 rotates, allowing the end slide rod 322 to extend and contact the ground. Figure 3As shown, when the telescopic rod 32 retracts, the winding belt 4 follows the retraction of the telescopic rod 32 and is wound onto the winding device 2. This invention installs a trunk pedal device 100 inside the vehicle's trunk 92. The telescopic rod 32 is extended by the telescopic motor 31, and the winding device 2 drives the winding belt 4 to release as the telescopic rod 32 extends, forming a flat pedal. The rotating motor 5 drives the telescopic device 3 to rotate at an angle, causing the final sliding rod 322 to abut against the ground. The flat pedal forms an inclined surface. Items to be transported are placed on the flat pedal and slide into the trunk 92 via the flat pedal. The sliding friction between the item and the flat pedal replaces direct lifting of the item, reducing labor intensity, saving physical strength, and facilitating personnel operation.

[0031] Specifically, the trunk pedal device 100 is installed inside the trunk 92, and the trunk pedal device 100 includes an unfolded state for use (e.g., Figure 1 ) and the rolled-up state when not in use (e.g. Figure 3 When it is necessary to move items, the trunk pedal device 100 is activated, the telescopic motor 31 drives the telescopic rod 32 to extend, and the reel device 2 drives the winding belt 4 to slowly release as the telescopic rod 32 extends. When the telescopic rod 32 extends outside the vehicle, the rotating motor 5 drives the telescopic device 3 to rotate at an angle, so that the telescopic rod 32 tilts downward until the end section of the telescopic rod 322 is fully extended and in contact with the ground. Place the items on the inclined flat pedal and push or pull the items towards the trunk 92 so that the items slide along the flat pedal into the trunk 92. The sliding friction between the items and the flat pedal replaces the direct lifting of the items, reducing labor intensity, saving physical strength, and facilitating personnel operation. When not in use, the trunk pedal device 100 is closed, the telescopic motor 31 drives the telescopic rod 32 to retract, and the winding device 2 drives the winding belt 4 to retract along with the telescopic rod 32. When the telescopic rod 32 is retracted into the trunk, the rotating motor 5 drives the telescopic device 3 to rotate at an angle to return to the center position. The telescopic rod 32 continues to retract until the final slide bar 322 is fully retracted, the winding device 2 stops winding the winding belt 4, and the trunk pedal device 100 is locked and placed inside the trunk 92. Further,

[0032] As one implementation method, such as Figure 1As shown, the winding device 2 includes a drive motor 21, a drum 23, and a winding rod 22. The output end of the drive motor 21 is connected to the winding rod 22, and the drum 23 is sleeved on the winding rod 22. The initial section of the take-up tape 4 is fixedly connected to the drum 23, and the take-up tape 4 is wound around the drum 23. The final section of the take-up tape 4 is fixedly connected to the telescopic rod 32. The winding rod 22 takes up and unwinds the tape 4 by rotating the drive motor 21. The rotation speed of the drive motor 21 is the same as the driving speed of the telescopic motor 31. The take-up tape 4 can be made of rubber, which has the characteristics of high friction, high heat resistance, and low price. It also has the characteristics of flexible materials that can be bent yet tough.

[0033] As one implementation method, such as Figure 1 As shown, there are at least two telescopic devices 3, respectively located at both ends of the reel device 2. The two sides of the take-up belt 4 are connected to the adjacent telescopic rods 32. The take-up belt 4 is released and wound up accordingly by the extension and retraction of the telescopic rods 32 on both sides, so that the take-up belt 4 can form a flat platform for transporting goods. Of course, three or four telescopic devices 3 can also be provided, distributed below the take-up belt 4, extending and retracting synchronously with the telescopic devices 3 on both sides, providing support for the flat platform, making the force stable during the transport of goods, and able to support heavier items.

[0034] As one implementation method, such as Figure 4 As shown, each section of the telescopic rod 32 has a groove 323 on the side of the initial section 321, the middle section 325, and the final section 322 near the take-up belt 4, along the length L of the telescopic rod 32. A connecting block 324 is fixed to the inner wall of the final section 322 at the groove 323. The side of the final section of the take-up belt 4 is connected to the final section 322 via the connecting block 324. Both sides of the take-up belt 4 move within the groove 323 of the telescopic rod 32. The connecting block 324 can be fixed to the inner wall of the final section 322 by rivets or nuts; the connecting block 324 can be made of magnet material and is magnetically attracted and fixed to the inner wall of the final section 322. Furthermore, multiple connecting blocks 324 can be provided to make the connection between the take-up belt 4 and the telescopic rod 32 more secure. Furthermore, the final slide bar 322 can be disassembled into two halves along its axial direction, including a left half and a right half. The left and right halves can be connected by bolts or clips. By making the final slide bar 322 a detachable structure, it is easier to install the connecting block 324 inside the final slide bar 322, making assembly more convenient. Of course, the side of the final section of the winding tape 4 can also be directly bonded and fixed to the inner wall of the final slide bar 322.

[0035] As one implementation method, such as Figure 2 and Figure 3As shown, the end of the final slide bar 322 is provided with a grounding stabilizing device 6. When the telescopic rod 32 extends to the point where the final slide bar 322 contacts the ground, the grounding stabilizing device 6 pops out and contacts the ground. In this embodiment, by setting the grounding stabilizing device 6, the contact area between the trunk pedal device 100 and the ground is increased, thereby improving the stability of the device during use.

[0036] In one embodiment, the grounding stabilization device 6 includes a pressure sensor 61, a stabilizing rod 62, and a rotation limiting mechanism 63. The stabilizing rod 62 is connected to the end of the final slide rod 322 via the rotation limiting mechanism 63, and the pressure sensor 61 is mounted on the rotation limiting mechanism 63. In this embodiment, the final slide rod 322 and the stabilizing rod 62 are connected via the rotation limiting mechanism 63. When the final slide rod 322 extends and touches the ground, the pressure sensor 61 senses a pressure change and transmits the signal to the controller 7. The controller 7 activates the rotation limiting mechanism 63, which drives the stabilizing rod 62 to rotate away from the telescopic rod 32 until it contacts the ground and then locks the stabilizing rod 62 to prevent the stabilizing rod 62 from rotating under force during the transportation of goods, thus improving the stability of the device.

[0037] Specifically, the rotation limiting mechanism 63 includes a fixed base (not shown) and a servo motor (not shown). One end of the fixed base is connected to the end slide bar 322. The servo motor is installed inside the fixed base, and the output end of the servo motor is connected to the stabilizing rod 62. The pressure sensor 61 is located at the bottom of the fixed base. When the end slide bar 322 touches the ground, the fixed base also touches the ground. The pressure sensor 61 senses the pressure change and transmits the signal to the controller 7. The controller 7 controls the servo motor to start, driving the stabilizing rod 62 from the position of contacting the end slide bar 322 to contacting the ground and locking it. When the end slide bar 322 is retracted to the point of being off the ground, the pressure sensor 61 senses the pressure change to zero and transmits the signal to the controller 7. The controller 7 controls the servo motor to start, driving the stabilizing rod 62 from the position of contacting the ground to contacting and locking the end slide bar 322.

[0038] In this embodiment, the stabilizing rod 62 can also be configured to be fixedly connected to the end slide rod 322, and the stabilizing rod 62 and the end slide rod 322 form an acute angle. When the end slide rod 322 is retracted, the stabilizing rod 62 is exposed at the end of the end slide rod 322.

[0039] As one implementation method, such as Figure 5 As shown, the rotating motor 5 is mounted on the fixed frame 1. The output end of the rotating motor 5 is connected to the telescopic motor 31, so that the rotating motor 5 drives the telescopic motor 31 to rotate, thereby driving the telescopic rod 32 to rotate as well. One rotating motor 5 is connected to one telescopic device 3.

[0040] In one embodiment, the trunk pedal device 100 also includes a slide rail (not shown) for installation inside the trunk 92. The slide rail is located below the telescopic rod 32, and the tilt angle of the slide rail is the same as the tilt angle of the telescopic rod 32 after rotation. In this embodiment, there are two slide rails, respectively corresponding to the telescopic devices 3 on both sides of the roller device 2. When the telescopic rod 32 rotates to a certain angle and tilts downward, it just contacts the slide rail. The slide rail can support the telescopic rod 32 and prevent the telescopic rod 32 from deforming when carrying excessively heavy items. Furthermore, the two slide rails can be fixed to the inner walls on both sides of the trunk 92, without occupying the storage space on the floor of the trunk 92, thus improving the space utilization of the trunk 92.

[0041] In one implementation, the end of the final slide bar 322 is provided with a grounding stabilizing device 6, and the trunk pedal device 100 also includes a controller 7, which is electrically connected to the reel device 2, the telescopic device 3, the rotating motor 5, and the grounding stabilizing device 6. Specifically, the controller 7 controls the start and stop of the drive motor 21, the telescopic motor 31, the rotating motor 5, and the rotation limit mechanism 63 to realize the transformation of the trunk pedal device 100 between the unfolded state and the retracted state.

[0042] In one embodiment, the mounting bracket 1 includes a vertical support rod (not shown). The vertical support rod can be configured as a telescopic support rod, and the height of the trunk pedal device 100 can be adjusted by adjusting the length of the vertical support rod to accommodate vehicles of different heights, thereby improving the applicability and versatility of the device. After the height of the vertical support rod of the mounting bracket 1 is adjusted, the rotation angle of the telescopic rod 32 driven by the rotary motor 5 should also be adjusted accordingly to ensure that the end slide rod 322 of the telescopic rod 32 can contact the ground after it is fully extended.

[0043] The present invention also provides a vehicle, such as Figure 6 As shown, the vehicle includes a trunk step device 100 as described above, which is installed inside the trunk 92 of the vehicle. The vehicle's center console 8 is connected to the controller 7 of the trunk step device 100 to control the opening and closing of the trunk step device 100. The trunk step device 100 can also be opened and closed by a button on the trunk lid 91. When the trunk lid 91 is opened, the trunk step device 100 can be opened into an unfolded state via the controller 7, the center console 8, or the button on the trunk lid 91, ready for loading and unloading items; when the trunk lid 91 is closed, the trunk step device 100 is locked.

[0044] This invention installs a trunk pedal device 100 inside the trunk 92 of a vehicle. A telescopic motor 31 drives a telescopic rod 32 to extend, and a reel device 2 drives a winding belt 4 to release as the telescopic rod 32 extends, forming a flat pedal. A rotating motor 5 drives the telescopic device 3 to rotate at an angle so that the end slide rod 322 abuts against the ground, forming an inclined surface on the flat pedal. Items to be transported are placed on the flat pedal and slide into the trunk 92. The sliding friction between the item and the flat pedal replaces the direct lifting of the item, reducing labor intensity, saving physical strength, and facilitating personnel operation.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content without departing from the scope of the technical solution of the present invention, which are equivalent embodiments with equivalent changes. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the technical solution of the present invention shall still fall within the protection scope of the technical solution of the present invention.
