[0055] The driving device can include a driving piece 300 and a transmission shaft assembly 500 connected with the driving piece 300, and the transmission shaft assembly 500 is connected with the winding reel 210. Specifically, the driving piece 300 is used to drive the transmission shaft assembly 500 to rotate, the transmission shaft assembly 500 drives the winding reel 210 to rotate, the take-up or pay-off of the traction rope 220 is realized, the movement of the traction rope 220 drives the movable support 110 to move up and down relative to the mounting rack 800, so that the storage plate moves up and down.

[0057] To solve the above problems, in the embodiment of the utility model, please refer to Figure 3 , Figure 3 The structure diagram of the transmission shaft assembly of the embodiment of the utility model, the transmission shaft assembly 500 includes a connecting rod 510 and a rotating shaft 520, the connecting rod 510 and the rotating shaft 520 are coaxially arranged. Among them, the connecting rod 510 is constructed as a hollow rod, the rotating shaft 520 is connected to at least one end of the connecting rod 510 in the axial direction, and the rotating shaft 520 is connected with the traction assembly 200.

[0058] In the utility model, transmission shaft assembly 500 is connected by connecting rod 510 and rotating shaft 520, and rotating shaft 520 and connecting rod 510 can be produced and processed independently, and the length of rotating shaft 520 is far shorter than the length of the whole transmission shaft assembly 500, compared with the long shaft processing mode in the related art, short shaft machining is not easy to vibrate, greatly reduces the processing difficulty, and the processing cost can be reduced.

[0059] Rotating shaft 520 can be processed and formed by metal or plastic, for example, the material of rotating shaft 520 can be steel, aluminum, POM (Polyoxymethylene, also known as polyformaldehyde) and the like.

[0060] Connecting rod 510 is a hollow rod, in order to ensure that connecting rod 510 has sufficient rigidity and strength, connecting rod 510 is made of metal profile material, so that connecting rod 510 has good deformation resistance, avoids torsional deformation of connecting rod 510 due to large torque, and prevents bending deformation of connecting rod 510 due to large suspended span. For example, in an embodiment, connecting rod 510 is made of stainless steel pipe profile.

[0061] In an embodiment, in order to ensure the stability and reliability of the lifting movement of storage plate assembly 100, a traction assembly 200 is arranged on both sides of storage plate assembly 100. Correspondingly, rotating shaft 520 is provided with two, and the two rotating shafts 520 are respectively connected to the axial ends of connecting rod 510, each rotating shaft 520 is connected with a traction assembly 200, and driving member 300 is connected with one of the rotating shafts 520. Wherein, driving member 300 is a driving motor, which can be arranged on the radial side of connecting rod 510, that is, on one side of the outer circumferential surface of connecting rod 510.

[0062] Specifically, referring to Figure 1 And Figure 2 As shown, along the axial direction of transmission shaft assembly 500, the rotating shaft 520 located on the left side of connecting rod 510 is defined as the first rotating shaft, the rotating shaft 520 located on the right side of connecting rod 510 is defined as the second rotating shaft, the first rotating shaft is connected with driving member 300 through transmission mechanism 400, driving member 300 drives the first rotating shaft to rotate through transmission mechanism 400, the first rotating shaft drives connecting rod 510 to rotate synchronously, and connecting rod 510 drives the second rotating shaft to rotate synchronously, so that the first rotating shaft and the second rotating shaft rotate synchronously, and drive storage plate assembly 100 to move stably up and down through the two traction assemblies 200 respectively.

[0063] The transmission mechanism 400 can adopt a gear set transmission mechanism or a belt transmission mechanism, and in the embodiment, only the gear set is taken as an example for illustration, and this cannot be regarded as a limitation to the present application.

[0064] In order to facilitate the assembly of the rotating shaft 520 and the connecting rod 510, in some embodiments, the rotating shaft 520 is inserted into the connecting rod 510. Please refer to Figures 4 to 6 Figure 4 A structural schematic view of the connecting rod of the present application, Figure 5 A structural schematic view of the rotating shaft of the present application, Figure 6 A first sectional view of the transmission shaft assembly of the present application. The connecting rod 510 is provided with an inner hole 511 which penetrates along the axial direction of the connecting rod 510, and the rotating shaft 520 includes a first shaft body 521 and a second shaft body 522 which is connected with the first shaft body 521, the first shaft body 521 is connected with the traction assembly 200, and the second shaft body 522 is inserted into the inner hole 511. It can be understood that by inserting the rotating shaft 520 into the inner hole 511 of the connecting rod 510, the existing hole and shaft are directly connected, and there is no need to process a complex connecting structure on the connecting rod 510 and the rotating shaft 520, which further simplifies the processing and can further reduce the production cost.

[0065] In some embodiments, the outer diameter of the second shaft body 522 is smaller than the outer diameter of the first shaft body 521, and a stepped surface 5211 is formed between the second shaft body 522 and the first shaft body 521. Please refer to Figure 6 As shown in the figure, the end of the connecting rod 510 abuts against the stepped surface 5211, so that in the assembly process of the rotating shaft 520 and the connecting rod 510, the rotating shaft 520 is axially positioned through the abutting action of the stepped surface 5211 and the end of the connecting rod 510, the quick assembly is realized, and the production efficiency is improved.

[0066] In order to facilitate the rotation of the connecting rod 510, the second shaft body 522 can be in interference fit with the inner hole 511, that is, the two are in tight fit, so that the rotating shaft 520 and the connecting rod 510 are firmly connected as a whole. When the driving member 300 drives the rotating shaft 520 to rotate, the rotating shaft 520 can stably transmit the torque to the connecting rod 510, so as to stably drive the connecting rod 510 to rotate. Moreover, the second shaft body 522 is in interference fit with the inner hole 511, so that after the rotating shaft 520 and the connecting rod 510 are inserted, there is no need to use screws for locking, the screws are saved, the material cost is reduced, the installation step of the screws is saved, and the production efficiency is improved.

[0067] ​During the lifting movement of the shelf plate assembly 100 driven by the traction assembly 200, the weight of the shelf plate and the objects carried on the shelf plate acts on the transmission shaft assembly 500, so that the transmission shaft assembly 500 bears a large load. If only the interference fit between the rotating shaft 520 and the connecting rod 510 is relied on to transmit torque, the rotating shaft 520 is prone to slip (i.e., the rotating shaft 520 rotates while the connecting rod 510 does not rotate) when the load is too large.

[0068] To this end, in some embodiments, please refer to Figure 4 and Figure 7 , Figure 7 for Figure 3 the local enlarged view of B in FIG. 5B, the connecting rod 510 is provided with a limiting groove 512, the limiting groove 512 penetrates the rod wall of the connecting rod 510, the limiting groove 512 is in communication with the inner hole 511, and the outer circumferential surface of the second shaft body 522 is provided with a protruding portion 5221, the protruding portion 5221 is inserted into the limiting groove 512.

[0069] By providing the protruding portion 5221 on the outer circumferential surface of the rotating shaft 520, the protruding portion 5221 is inserted into the limiting groove 512, so that the rotating shaft 520 and the connecting rod 510 are not only in an insertion relationship, but also are engaged together through the protruding portion 5221. The protruding portion 5221 is equivalent to a force applying arm inserted into the connecting rod 510 from the rotating shaft 520. When the rotating shaft 520 rotates, the protruding portion 5221 exerts a pushing force on the groove wall of the limiting groove 512, which can better transmit torque to the connecting rod 510, thereby better driving the connecting rod 510 to rotate, and effectively avoiding the slipping and idling of the rotating shaft 520.

[0070] The plurality of protruding portions 5221 can be uniformly arranged around the axis of the rotating shaft 520. Of course, the number of protruding portions 5221 cannot be too large, so as to avoid setting too many limiting grooves 512 on the connecting rod 510, thereby reducing the connection strength of the connecting rod 510 and the rotating shaft 520. The specific number of protruding portions 5221 is determined according to actual rotation requirements. In an embodiment, the protruding portion 5221 is provided as two.

[0071] In some embodiments, the limiting groove 512 extends along the axial direction of the connecting rod 510 from the end of the connecting rod 510, and the limiting groove 512 is a non-closed groove. During the assembly of the rotating shaft 520 and the connecting rod 510, as the second shaft body 522 is inserted into the inner hole 511, the protruding portion 5221 can be directly inserted into the limiting groove 512, which is convenient and fast to assemble, and can improve production efficiency. Moreover, when the transmission shaft assembly 500 needs to be maintained subsequently, for example, when the rotating shaft 520 needs to be replaced, the rotating shaft 520 and the connecting rod 510 can also be quickly and conveniently disassembled and separated, which is beneficial to subsequent maintenance.

[0072] The limiting groove 512 is designed as a rectangular groove, and the cross-sectional shape of the protruding part 5221 is designed as a rectangle, so that the limiting groove 512 and the protruding part 5221 are designed as regular shapes, which is beneficial to processing and further reduces production cost.

[0073] In an embodiment, please refer to Figures 8 to 10 , Figure 8 It is an assembly structure diagram of the transmission shaft assembly and the support seat of the utility model embodiment, Figure 9 It is a first sectional view of the transmission shaft assembly and the support seat assembly of the utility model embodiment, Figure 10 It is a second sectional view of the transmission shaft assembly and the support seat assembly of the utility model embodiment, the shelf 10 further comprises a support seat 700 and a shaft sleeve 600, the support seat 700 is provided with a through hole 713, and at least part of the shaft sleeve 600 is installed in the through hole 713; the shaft sleeve 600 is provided with a shaft hole (not marked), the transmission shaft assembly 500 is arranged in the shaft hole and rotationally matched with the shaft hole, and the shaft sleeve 600 is located at the connecting position of the rotating shaft 520 and the connecting rod 510, so that at least the limiting groove 512 and the protruding part 5221 are located in the shaft hole.

[0074] The torque is mainly transmitted between the rotating shaft 520 and the connecting rod 510 through the cooperation of the protruding part 5221 and the limiting groove 512, since the limiting groove 512 is opened, the end of the connecting rod 510 is relatively weak, and when the torque is too large, it is easy to cause deformation or damage, the support seat 700 and the shaft sleeve 600 are arranged to support the rotating shaft 520 and the connecting rod 510, and the shaft sleeve 600 is arranged at the connecting position of the rotating shaft 520 and the connecting rod 510, so that at least part of the limiting groove 512 and the protruding part 5221 are located in the shaft sleeve 600, the shaft sleeve 600 covers the torque transmission part of the rotating shaft 520 and the connecting rod 510, the shaft sleeve 600 and the support seat 700 can assist the transmission of torque, prevent the deformation or damage of the protruding part 5221 and the limiting groove 512 caused by too large torque, and ensure the stability and reliability of the rotation of the rotating shaft 520 and the connecting rod 510.

[0075] Moreover, the support seat 700 and the shaft sleeve 600 jointly support the transmission shaft assembly 500, by sleeving the shaft sleeve 600 at the connecting position of the rotating shaft 520 and the connecting rod 510, part of the load borne by the rotating shaft 520 can be shared by the shaft sleeve 600 to the support seat 700, preventing the rotating shaft 520 from being biased downward due to too large load, which is beneficial to the rotation of the rotating shaft 520 and the connecting rod 510.

[0076] The shaft hole of the shaft sleeve 600 can be configured with high smoothness, which can reduce the friction when the rotating shaft 520 and the connecting rod 510 rotate, and further facilitate the rotation of the rotating shaft 520 and the connecting rod 510.

Wherein, at least part of the first protruding part 5221a is located in the shaft hole, the second protruding part 5221b is located outside the shaft hole and protrudes from the outer circumferential surface of the connecting rod 510, and is located on one side of the shaft sleeve 600.

[0078] The second protruding part 5221b can position the assembly process of the transmission shaft assembly 500 and the shaft sleeve 600 and the support seat 700. Specifically, please refer to Figure 11 , Figure 11 for the schematic diagram of the transmission shaft assembly and the support seat of the utility model embodiment, first install the shaft sleeve 600 to the through hole 713 of the support seat 700, and then pass the transmission shaft assembly 500 through the shaft sleeve 600, because the second protruding part 5221b protrudes from the outer circumferential surface of the connecting rod 510, the second protruding part 5221b can be used for positioning the assembly of the transmission shaft assembly 500, during the process of passing the transmission shaft assembly 500 through the shaft sleeve 600, when the transmission shaft assembly 500 moves to the second protruding part 5221b and blocks it from continuing to pass through, it means that the transmission shaft assembly 500 is inserted in place, and then the transmission mechanism 400, the traction assembly 200 and the rotating shaft 520 are connected. In this way, by positioning the assembly process through the second protruding part 5221b, the assembly efficiency of the transmission shaft assembly 500 and the shaft sleeve 600 and the support seat 700 can be improved, and the production efficiency is improved.
