DETAILED DESCRIPTION

[0026] The present invention is further illustrated by the following examples, which are intended to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the present invention.

[0028] An automatic lifting access rack includes a pair of lifting access devices arranged opposite to each other and a storage platform 3 mounted between the lifting access devices; the lifting access devices include a fixed support 1 and a driving mechanism 4 mounted on the support 1 and driving the storage platform 3 to move. Figure 1 As shown, the carrier 1 is a vertically fixed plate, which is used to distribute the pressure of the storage platform 3 to both sides and can also serve as a mounting carrier for the driving mechanism 4.

[0029] like Figure 2 As shown, the driving mechanism 4 includes a power gear 41 arranged on a fixed axis, a rack 42 slidably connected to the carrier 1 and a power unit 43 driving the power gear 41 to rotate.

[0030] like Figure 3 As shown, two guide grooves 11 are provided on the bearing member 1, each guide groove 11 has a transverse slot section 111 and a vertical slot section 112, and the transverse slot section 111 and the vertical slot section 112 in the same guide groove 11 are connected, the transverse slot sections 111 of different guide grooves 11 are vertically staggered by a distance, and the vertical slot sections 112 of different guide grooves 11 are transversely staggered by a distance.

[0031] like Figure 4 As shown, the rack 42 has a horizontal rack section 421 and a vertical rack section 422; the rack 42 has a guide portion 423 that slides with the guide groove 11. The guide portion 423 can be a cylindrical member protruding laterally, or a roller installed on the side of the rack 42 and capable of being embedded in the guide groove 11. Figure 4 Only a cylindrical member is used as an example. There are two guide parts 423, one is provided in the horizontal rack segment 421, and the other is provided in the vertical rack segment 422, and the two guide parts 423 are staggered by a distance in the horizontal and vertical directions, so as to match the guide groove 11 one to one. In addition, since the two guide parts 423 are staggered by a distance in the horizontal and vertical directions, when the two guide parts 423 slide along their respective corresponding horizontal slot segments 111, one of the guide parts 423 is subjected to an upward support force, and the other guide part 423 is subjected to a downward pressure, and there is a large horizontal distance between the positions of the two forces, thereby generating a large torque to balance the torque generated by the downward pressure of the storage platform 3 on the rack 42; similarly, when the two guide parts 423 slide along their respective corresponding vertical slot segments 112, there is a large vertical distance between the two guide parts 423, thereby ensuring that the rack 42 slides vertically without rotating. Through the cooperation between the guide groove 11 and the guide portion 423 of the above structure, the rack 42 can slide vertically and horizontally, but will not rotate.

[0032] like Figure 5As shown, the power gear 41 has a first tooth portion 411 and a second tooth portion 412. When the guide portion 423 is located in the horizontal notch section 111, the first tooth portion 411 meshes with the horizontal rack section 421; when the guide portion 423 is located in the vertical notch section 112, the second tooth portion 412 meshes with the vertical rack section 422. Therefore, when the power gear 41 rotates in one direction, the second tooth portion 412 first drives the vertical rack section 422 to move vertically, and then drives the horizontal rack section 421 to move horizontally. Similarly, rotating the power gear 4 in the opposite direction can reset the rack 42. The storage platform 3 is fixedly connected to the rack 42, for example, by bolting, snap-fitting, welding, or other connection methods. In this way, when the rack 42 performs lifting and translational movements, it drives the storage platform 3 to perform lifting and translational movements synchronously.

[0033] like Figure 4 、 5 As shown, in some embodiments, the first tooth portion 411 has more teeth than the second tooth portion 412; the diameter of the first tooth portion 411 is larger than the second tooth portion 412; and the length of the horizontal rack segment 421 is longer than the vertical rack segment 422. In this way, the vertical movement distance of the storage platform 3 is relatively short, while the horizontal movement distance is longer.

[0034] like Figure 6 As shown, in some embodiments, the power unit 43 includes a transmission wheel 431 coaxially connected to the power gear 41, a worm 432 meshing with the transmission wheel 431, and a motor 433 that drives the worm 432 to rotate; the worm 432 is in one-way transmission engagement with the transmission wheel 431. The outer periphery of the transmission wheel 431 has worm teeth or helical teeth that cooperate with the worm 432. The rotation of the worm 432 can drive the transmission wheel 431 to rotate, thereby driving the power gear 41 to rotate, and ultimately driving the storage platform 3 to move. However, since the transmission wheel 431 cannot drive the worm 432 to rotate in the opposite direction, the power unit 43 has its own locking function. The advantage brought by this is that there is no need to set up an additional locking structure. The storage platform 3 stays in any position and will not slide arbitrarily due to external forces.

[0035] like Figure 3 and 7As shown, in some embodiments, the automatic lifting in and out storage rack further includes a trigger member 5 arranged in the guide groove 11, and the trigger member 5 is located in the transverse slot section 111; when the guide portion 423 passes through the trigger member 5, the trigger member 5 is triggered to send a trigger signal. Preferably, the trigger member 5 is a micro switch embedded in the guide groove 11. The provision of the trigger member 5 can accurately determine whether the storage platform 3 is in the fully extended position, so as to facilitate electronic control operation. Usually, the trigger member 5, the motor 433 and the power supply are all connected to the electronic control unit. When the guide portion 423 moves to the trigger member 5, the trigger member 5 generates a trigger signal. The electronic control unit can determine that the storage platform 3 is in the fully extended position after receiving the trigger signal. The function of this position judgment can provide a basis for electronic control operation.

[0036] like Figure 8 、 9 As shown, in some embodiments, if the power unit 43 does not have a self-locking function, an electromagnetic telescopic pin 6 can be used to lock the rack 42. Specifically, the electromagnetic telescopic pin 6 is further provided on the carrier 1, and the rack 42 also has a pin hole 424. The electromagnetic telescopic pin 6 is controllably inserted into the pin hole 424 to lock the rack 42.

[0037] like Figure 10 As shown, the aforementioned automatic lift access rack can be used in a vehicle trunk. Specifically, the lift access devices are fixed opposite each other on either side of the trunk, with the storage platform 3 positioned between them. The initial position of the storage platform 3 is toward the front and lower part of the vehicle. The drive mechanism 4 drives the platform 3 upward for a certain distance before sliding it toward the rear. This allows even petite users to easily access items stored deep within the trunk.

[0038] The above embodiments are exemplary and intended to illustrate the technical concepts and features of the present invention so that those skilled in the art can understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention are intended to be included within the scope of protection of the present invention.
