[0051] The following reference Figures 1 to 23 This application describes a lifting mechanism and toy according to some embodiments.

[0052] Example 1

[0053] See Figures 1 to 23 As shown, an embodiment of this application provides a lifting mechanism, including: a driving component 1, a gear 2, a first rack 3, a second rack 4, a primary lifting component 5, a secondary lifting component 6, a locking component 7, and a housing 8; wherein, the housing 8 is fixed at a target location as needed and remains stationary; along a first preset direction, an opening is formed at the top of the housing 8, the secondary lifting component 6 is disposed inside the housing 8 and can move up and down along the first preset direction; the secondary lifting component 6 has a second mounting cavity 61 extending through its top along the first preset direction and a second side opening on its side, the primary lifting component 5 is disposed inside the second mounting cavity 61 and can move up and down along the first preset direction; the second rack 4 is disposed inside the second mounting cavity 61 and extends from top to bottom along the first preset direction, the second rack 4 includes a toothless area 41 and a toothed area 42;

[0054] The first-stage lifting member 5 has a first mounting cavity 51 extending through its top along a first preset direction and a first side opening on its side. The first rack 3 is disposed in the first mounting cavity 51. The gear 2 is connected to the output end of the drive member 1, and the gear 2 can mesh with the toothed areas 42 of the first rack 3 and the second rack 4 respectively. When the first-stage lifting member 5 rises to a preset position relative to the second-stage lifting member 6, the locking assembly 7 can lock the first-stage lifting member 5 and the second-stage lifting member 6 together so that the first-stage lifting member 5 and the second-stage lifting member 6 rise and fall synchronously. When the first-stage lifting member 5 and the second-stage lifting member 6 fall to a preset position synchronously, the locking assembly 7 can release the locking connection between the first-stage lifting member 5 and the second-stage lifting member 6 so that the second-stage lifting member 6 can continue to fall and be stored back in the first-stage lifting member 5.

[0055] Based on the structure described above, the working process of the lifting mechanism provided in this application is as follows: In the initial state, the gear 2 is engaged with the first rack 3 and has no meshing relationship with the toothless area 41 of the second gear 2. The driving component 1 first drives the gear 2 to rotate, and the gear 2 drives the first rack 3 to move, thereby driving the first-stage lifting component 5 to rise first. When it rises to the preset position, the locking component 71 locks the first-stage lifting component 5 and the second-stage lifting component 6, thereby making the first-stage lifting component 5 and the second-stage lifting component 6 rise synchronously. At the same time, the gear 2 meshes with the toothed areas 42 of the first rack 3 and the second rack 4, making the first-stage lifting component 5 and the second-stage lifting component 6 more stable during the rising process, until both reach the limit position.

[0056] When it is necessary to lower and retract, the drive component 1 first drives the gear 2 to rotate, which in turn drives the first rack 3 and the second rack 4 to move downward synchronously, thereby driving the first-stage lifting component 5 and the second-stage lifting component 6 to descend synchronously until they reach the preset position. Then, the locking component 71 will release the locking connection between the first-stage lifting component 5 and the second-stage lifting component 6, so that the first-stage lifting component 5 can continue to descend and be stored back in the second-stage lifting component 6.

[0057] As can be seen, this application provides a novel lifting mechanism with a two-stage lifting structure, which enables a wide range of lifting to meet different usage needs. Moreover, the first-stage lifting component 5 can be hidden inside the second-stage lifting component 6, which saves space and helps with miniaturization design.

[0058] Furthermore, preferably, the secondary lifting member 6 is provided with second side openings on both sides along the second preset direction, and the secondary lifting member 6 is provided with a first side opening along the second preset direction and close to the gear 2. The first side opening corresponds to and is connected to the second side opening, so that the gear 2 can mesh with the first rack 3 and the second rack 4 through the first side opening and the second side opening.

[0059] Furthermore, preferably, both the first side opening and the second side opening extend along a first preset direction.

[0060] Furthermore, preferably, both the first rack 3 and the second rack 4 extend along a first preset direction.

[0061] Furthermore, preferably, the first preset direction is the vertical direction. Of course, it is not limited to this and can be designed as needed.

[0062] Furthermore, preferably, the second preset direction can be the Y direction in the horizontal plane, such as the width direction of the secondary lifting component 6. Of course, it is not limited to this and can be designed as needed.

[0063] Furthermore, preferably, the driving component 1 is a motor. Of course, it is not limited to this and can be selected according to actual needs.

[0064] It should be noted that this lifting mechanism is particularly suitable for use on toys, but it is not limited to these applications and can also be used on other equipment, depending on the specific needs.

[0065] In this embodiment, preferably, as follows: Figure 3 and Figure 4 As shown, the first-stage lifting component 5 has a first mounting cavity 51 and a first side opening; the inner wall of the first mounting cavity 51 has a limiting groove 52, and the length of the first rack 3 located in the area below the limiting groove 52 along the first preset direction is greater than or equal to the length of the toothless area 41. That is to say, the first rack 3 below the first limiting groove 52 can be called the lower rack 31, and the length of this lower rack 31 is greater than or equal to the length of the toothless area 41. This can compensate for the toothless area 41, so that the gear 2 can always mesh with the rack, ensuring the normal lifting of the device.

[0066] In this embodiment, preferably, as follows: Figure 6 , Figure 11 and Figure 23 As shown, the locking assembly 7 includes a locking member 71 and a spring 72; wherein, the locking member 71 and the spring 72 are both disposed on the secondary lifting member 6, and the locking member 71 and the secondary lifting member 6 are slidably connected along the second preset direction; in the initial state, one end of the spring 72 abuts against the inner wall of the outer shell 8, and the other end of the spring 72 abuts against the locking member 71.

[0067] When the first-stage lifting component 5 rises to its limit position relative to the second-stage lifting component 6, the spring 72 can push the locking component 71 to be inserted into the limiting groove 52 along the second preset direction, so that the second-stage lifting component 6 and the first-stage lifting component 5 are locked together.

[0068] Further, preferably, such as Figures 11 to 15 As shown, the inner wall of the outer casing 8 forms a limiting protrusion 81, and the locking member 71 forms a limiting through hole 715 arranged along the first preset direction. The limiting protrusion 81 can be inserted into the limiting through hole 715 to limit the locking member 71 in the second preset direction.

[0069] As can be seen from the structure described above, when the first-stage lifting member 5 rises to its limit position relative to the second-stage lifting member 6, the limiting protrusion 81 disengages from the limiting through hole 715, that is, the limiting of the locking member 71 is released. Under the push of the spring 72, the locking member 71 moves along the second preset direction, such as the horizontal direction, and inserts into the limiting groove 52 on one side, thereby connecting the first-stage lifting member 5 and the second-stage lifting member 6 together. The two can then rise synchronously, that is, complete two rises, thereby increasing the total height of the rise to meet different needs.

[0070] When the secondary lifting component 6 and the primary lifting component 5 descend to their extreme positions simultaneously, the limiting protrusion 81 re-inserts into the limiting through hole 715, causing the locking component to move out of the limiting through hole 715, thereby releasing the connection between the primary lifting component 5 and the secondary lifting component 6. Then, the primary lifting component 5 can be driven to continue descending independently and stored back into the secondary lifting component 6, saving space.

[0071] In this embodiment, preferably, as follows: Figure 6 , Figure 11 , and 17 and Figure 19 As shown, the secondary lifting component 6 has a sliding groove 62 arranged along a second preset direction, and the sliding groove 62 is connected to the second mounting cavity 61 along a third preset direction; the locking component 71 includes a limiting part 711, a sliding part 712, a connecting part 713 and a mating part 714 connected sequentially along the third preset direction, and the sliding part 712 is slidably disposed in the sliding groove 62; along the third preset direction, a first mounting groove 63 is provided on the side of the sliding groove 62 and is connected thereto, and a mounting protrusion 64 is formed in the first mounting groove 63, and the spring 72 is disposed in the groove and sleeved on the mounting protrusion 64;

[0072] The mating part 714 is disposed in the first mounting groove 63 and is movably sleeved on the mounting protrusion 64. The mating part 714 is pressed between the spring 72 and the bottom wall of the first mounting groove 63 along the second preset direction.

[0073] As can be seen from the structure described above, the mating part 714 acts in conjunction with the spring 72, thereby driving the locking member 71 to move as a whole; the sliding part 712 can slide in the first mounting groove 63, thereby driving the limiting part 711 to insert or move out of the limiting groove 52, thereby realizing the locking connection or release connection of the first-stage lifting member 5 and the second-stage lifting member 6.

[0074] Furthermore, preferably, the sliding part 712, the limiting part 711, and the mating part 714 are an integral structure. Of course, it is not limited to this and can also be a separate structure that is assembled together later.

[0075] Furthermore, preferably, the limiting portion 711 forms a limiting through hole 715.

[0076] Furthermore, preferably, there are two sliding portions 712, which are respectively disposed on opposite sides of the limiting portion 711 along the third preset direction.

[0077] Furthermore, preferably, the number of mating parts 714 is also two, and they are respectively disposed on opposite sides of the two sliding parts 712 along the third preset direction. Correspondingly, the number of connecting parts 713 is also two, and they correspond one-to-one with the two mating parts 714 and the two sliding parts 712.

[0078] Furthermore, preferably, the second preset direction can be the X direction in the horizontal plane, such as the length direction of the secondary lifting component 6. Of course, it is not limited to this and can be designed as needed.

[0079] As can be seen, the locking member 71 employs two sliding parts 712, two mating parts 714, and one limiting part 711, meaning it uses a symmetrical structure, thus improving the reliability of the locking member 71 during operation. Of course, the structure of the locking member 71 is not limited to the above and can be designed according to actual needs.

[0080] In this embodiment, preferably, as follows: Figure 5 and Figure 6 As shown, the lifting mechanism also includes a first limit switch 9, and along the first preset direction, the first limit switch 9 is disposed near the top of the housing 8, and can touch the first limit switch 9 when the secondary lifting component 6 rises to the limit position.

[0081] As can be seen from the structure described above, when the secondary lifting component 6 rises to the limit position, it can touch the first limit switch 9, thereby stopping the upward movement. In other words, the first limit switch 9 is used to detect when the whole structure has risen to the highest position.

[0082] Furthermore, preferably, the first limit switch 9 can be fixed on the side wall of the housing 8.

[0083] In this embodiment, preferably, as follows: Figure 7 and Figure 8 As shown, the lifting mechanism also includes a second limit switch 10, and along the first preset direction, the first limit switch 9 is located near the bottom of the housing 8, and can touch the second limit switch 10 when the first-stage lifting component 5 descends to the limit position.

[0084] As can be seen from the structure described above, when the first-stage lifting component 5 descends to its limit position, it can touch the second limit switch 10, thereby stopping the descent. In other words, the second limit switch 10 is used to detect the state of complete retraction.

[0085] Furthermore, preferably, the first limit switch 9 can be fixed on the side wall or bottom wall of the housing 8, depending on the actual needs.

[0086] In this embodiment, preferably, as follows: Figure 1 As shown, the lifting mechanism also includes a gear 2 transmission assembly, and the driving component 1 can be connected to the gear 2 through the gear 2 transmission assembly.

[0087] As can be seen from the structure described above, the output direction of the drive component 1 can be changed by using the gear 2 transmission assembly, thereby allowing for a more efficient spatial layout and reducing the space occupied. Of course, this gear 2 transmission assembly can also be omitted, depending on the specific design requirements.

[0088] Furthermore, preferably, the lifting mechanism also includes a housing 8, and the gear 2 transmission components are all disposed inside the housing 8, that is, forming a gearbox 11, which serves to protect the aforementioned gear 2 transmission components.

[0089] Furthermore, preferably, the gearbox 11 is fixed to the outer wall of the housing 8. Of course, it is not limited to this. The gearbox 11 can also be fixed to a fixed target ground, depending on the actual needs.

[0090] In this embodiment, preferably, as follows: Figures 1 to 3 As shown, the lifting mechanism also includes a first bearing member 12, and the first bearing member 12 is disposed on the top of the first-stage lifting member 5 along a first preset direction.

[0091] As can be seen from the structure described above, the first load-bearing component 12 can be used to install some other parts as a support structure. Of course, it is not limited to this. Some other parts can also be directly connected to the first-stage lifting component 5, depending on the actual needs of the design.

[0092] Furthermore, preferably, the first supporting member 12 can be a circular platform, and preferably, the first supporting member 12 can be a circular turntable. Of course, it is not limited to this and can be selected according to actual needs.

[0093] In this embodiment, preferably, as follows: Figure 5 As shown, the secondary lifting component 6 is a rectangular frame structure that meets strength requirements and has internal space for easy installation of the primary lifting component 5. Furthermore, it eliminates the need for an opening on the first side during machining, thus improving production efficiency. Of course, the structure of the secondary lifting component 6 is not limited to the above and can be designed according to actual needs.

[0094] Furthermore, preferably, the aforementioned first mounting groove 63, slide groove 62, and mounting protrusion 64 are all provided on the crossbeam structure at the top of the square frame structure, but of course, it is not limited to this.

[0095] Furthermore, preferably, the second rack 4 is disposed on the inner wall of the square frame structure, but of course, it is not limited to this.

[0096] In this embodiment, preferably, as follows: Figure 10 As shown, the outer casing 8 includes a first casing 82 and a second casing 83, and the first casing 82 and the second casing 83 are detachably connected together along a second preset direction.

[0097] Furthermore, preferably, the first housing 82 and the second housing 83 are detachably connected by bolts. Of course, this is not the only option; they can also be connected by snap-fit ​​mechanisms, etc.

[0098] In summary, the detailed working process of this lifting mechanism is as follows:

[0099] In the initial state, gear 2 engages with the first rack 3 and has no meshing relationship with the toothless area 41 of the second gear 2. The driving component 1 first drives gear 2 to rotate, and gear 2 drives the first rack 3 to move, thereby driving the first-stage lifting component 5 to rise first. When the first-stage lifting component 5 rises to the limit position relative to the second-stage lifting component 6, the limiting protrusion 81 disengages from the limiting through hole 715, that is, the limiting of the locking component 71 is released. Under the push of the spring 72, the locking component 71 moves along the second preset direction, such as the horizontal direction, and inserts into the limiting groove 52 on one side, thereby connecting the first-stage lifting component 5 and the second-stage lifting component 6 together. The latter two can rise synchronously, that is, complete two rises, thereby increasing the total height of the rise to meet different needs.

[0100] When it is necessary to lower and retract, the drive component 1 first drives the gear 2 to rotate, which in turn drives the first rack 3 and the second rack 4 to move downward synchronously, thereby driving the first-stage lifting component 5 and the second-stage lifting component 6 to descend synchronously. When the second-stage lifting component 6 and the first-stage lifting component 5 descend to their limit positions, the limiting protrusion 81 re-inserts into the limiting through hole 715, causing the locking component to move out of the limiting through hole 715, thereby releasing the connection between the first-stage lifting component 5 and the second-stage lifting component 6. Then, the first-stage lifting component 5 can be driven to continue descending independently and stored back into the second-stage lifting component 6, saving space.

[0101] As can be seen, this application provides a novel lifting mechanism with a two-stage lifting structure, which enables a wide range of lifting to meet different usage needs. Moreover, the first-stage lifting component 5 can be hidden inside the second-stage lifting component 6, which saves space and helps with miniaturization design.
