Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] like Figure 1-5 As shown, a concealed loading platform device includes a vehicle body 10 and a loading platform 20. The vehicle body 10 is provided with a receiving cavity 30 and a front opening 31. The receiving cavity 30 is used to receive the loading platform 20. The front opening 31 communicates with the receiving cavity 30 and is used for the loading platform 20 to enter and exit. The loading platform 20 includes a support seat 21, a step ladder 22, and a railing 23. The railing 23 is hinged to the front side of the support seat 21 and can rotate relative to the support seat 21 between a folded position against the support seat 21 and an unfolded position perpendicular to the support seat 21. A guide member 40 is provided inside the receiving cavity 30, extending along the length of the receiving cavity 30. The support seat 21 and the guide member 40 are slidably engaged. The step ladder 22 is movably connected to the support seat 21.

[0027] In use, the loading platform 20 can slide along the guide component 40 to move out of the receiving cavity 30, and then push the step ladder 22 relative to the support seat 21 to support it on the ground. Then, the fence 23 can be rotated relative to the support seat 21 to the fence unfolded position, so that the fence 23 is perpendicular to the support seat 21, which can improve the safety of use. When not in use, the fence 23 can be rotated relative to the support seat 21 to the fence folding position, so that the fence 23 is against the support seat 21, and the step ladder 22 is pushed towards the support seat 21 to achieve the folding of the loading platform 20. Then, the folded loading platform 20 is moved into the receiving cavity 30, which can reduce the space occupied. Therefore, the hidden loading platform device provided by this utility model combines the loading platform 20 with the support seat 21, the step ladder 22 and the fence 23, and reasonably sets the connection relationship between the support seat 21, the step ladder 22 and the fence 23. At the same time, the receiving cavity 30 and the front opening 31 are provided on the vehicle body 10. By rotating the fence 23 to the fence folding position and pushing the step ladder 22 towards the support seat 21, the loading platform 20 can be folded, reducing the volume of the loading platform 20, reducing the space occupied, and facilitating the storage of the loading platform 20 in the receiving cavity 30 of the vehicle body 10. This avoids increasing the vehicle width due to the configuration of the loading platform 20.

[0028] The staircase 22 includes an upper staircase 221 and a lower staircase 222. The lower staircase 222 is rotatably connected to the upper staircase 221, and its bottom is for contact with the ground. In use, by rotating the lower staircase 222 away from the upper staircase 221, the bottom of the lower staircase 222 moves away from the upper staircase 221, and the contact between the lower staircase 222 and the ground provides support. When not in use, by rotating the lower staircase 222 closer to the upper staircase 221, the staircase 22 can be folded up, reducing the volume of the loading platform 20. Specifically, the lower ladder portion 222 is rotatably connected to the upper ladder portion 221 and can rotate relative to the upper ladder portion 221 between the lower ladder portion unfolded position and the lower ladder portion folded position. The bottom of the lower ladder portion 222 is used to contact the ground when the lower ladder portion 222 is in the unfolded position. The distance between the bottom of the lower ladder portion 222 and the upper ladder portion 221 when the lower ladder portion is in the unfolded position is greater than the distance between the bottom of the lower ladder portion 222 and the upper ladder portion 221 when the lower ladder portion is in the folded position.

[0029] The upper ladder section 221 is slidably mounted on the support base 21. In use, the upper ladder section 221 can be pulled out from under the support base 21, and the lower ladder section 222 can be rotated away from the upper ladder section 221 to the unfolded position, where the lower ladder section 222 provides support by contacting the ground. When not in use, the lower ladder section 222 can be rotated relative to the upper ladder section 221 to the folded position, and then the upper ladder section 221 and the lower ladder section 222 can be pushed downwards towards the support base 21, further reducing the volume of the loading platform 20.

[0030] As a further preferred embodiment of this utility model, the concealed loading platform device may also employ an entry / exit device 50, which is used to drive the loading platform 20 to move along the guide member 40. The entry / exit device 50 includes a power component 51, a guide rod 52, and a guide seat 53; the guide rod 52 extends along the length direction of the guide member 40 and is rotatably installed in the receiving cavity 30; the power component 51 is used to drive the guide rod 52 to rotate, the guide rod 52 is provided with threads, the guide seat 53 is threadedly sleeved with the guide rod 52, and the guide seat 53 is fixed on the bearing seat 21. In use, the guide rod 52 is driven to rotate forward by the power component 51, which causes the bearing seat 21 to move out of the receiving cavity 30 along the guide component 40. The guide rod 52 is driven to rotate in the opposite direction by the power component 51, which causes the bearing seat 21 to move into the receiving cavity 30 along the guide component 40. This facilitates the removal and movement of the loading platform 20, making it convenient to use. No manual labor is required to remove and move the loading platform 20, thus saving time and effort.

[0031] The guide seat 53 includes a main seat body 531 and a nut 532; the nut 532 is fixed to the main seat body 531 and is threadedly connected to the guide rod 52. The main seat body 531 is detachably fixed to the support seat 21. By adopting the above structure, during maintenance, the nut 532 can be removed from the support seat 21 along with the main seat body 531, facilitating the removal and replacement of the nut 532.

[0032] Specifically, the main seat 531 is fixed to the support seat 21 by a locking screw. The main seat 531 is provided with an adjustment groove extending along the length of the receiving cavity 30. The support seat 21 is provided with a threaded hole. The locking screw passes through the adjustment groove and is threaded into the threaded hole. By adopting the above structure, the installation position of the main seat 531 can be adjusted according to actual needs.

[0033] The power unit 51 includes a geared motor, the body of which is installed within the receiving cavity 30. The guide rod 52 is connected to the output shaft of the geared motor for easy connection.

[0034] The fence 23 includes an end fence 231 and a side fence 232. The end fence 231 is hinged to the front side of the support base 21. The side fence 232 is hinged to the side of the end fence 231 away from the stairs 22. The side fence 232 can rotate relative to the end fence 231 between a folded position and an unfolded position. When the side fence 232 is in the folded position, it is close to the end fence 231. When the side fence 232 is in the unfolded position, it is perpendicular to the end fence 231. In use, by rotating the side fence 232 relative to the end fence 231 to the unfolded position, the side fence 232 and the end fence 231 can respectively act as barriers at the front and sides of the support base 21, further improving safety.

[0035] The guiding component 40 includes a first slide rail 41, and the support seat 21 is slidably engaged with the first slide rail 41. The guiding component 40 also includes a second slide rail 42, with one side of the support seat 21 slidably engaged with the first slide rail 41 and the other side of the support seat 21 slidably engaged with the second slide rail 42. By adopting the above structure, the smoothness of the sliding of the support seat 21 can be improved.
