DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-4 The utility model provides a technical solution: an electric multi-directional shiftable shoe support frame, which provides users with an unprecedented personalized wearing experience. The support frame mainly includes a hollow shoe body 1, a sole shoe last shell 2, a heel shoe last shell 3 and an instep shoe last shell 4, wherein the sole shoe last shell 2 is carefully composed of two half shells, which can be flexibly slidably arranged at the front end of the hollow shoe body 1 to ensure the comfort and adaptability of the shoe, and the heel shoe last shell 3 is cleverly rotatably installed at the tail of the hollow shoe body 1 to provide users with a more fitting support.

[0035] The instep last shell 4 is movably arranged at the instep position of the hollow shoe body 1, and can be fine-tuned according to the user's foot shape to make the shoe fit the instep more closely and reduce the discomfort of foot rubbing. The multi-directional electric expansion component 5 is the core of this support frame. It is hidden inside the hollow shoe body 1, and through the precise connection with the heel last shell 3, the sole last shell 2 and the instep last shell 4, it realizes the multi-directional expansion function of the corresponding last shell.

[0036] The double-form expansion component 51 in the multi-directional electric expansion component 5 is located at the front end of the hollow shoe body 1, and it has two expansion forms. By rotating a screw 511 installed at the front end of the hollow shoe body 1, a trapezoidal top block 512 will move along the thread of the screw 511, and an inclined guide groove 513 matching the trapezoidal top block 512 is provided on the inner sides of the two half shells of the sole shoe last shell 2. When the trapezoidal top block 512 moves, it will push the inclined guide groove 513, thereby driving the sole shoe last shell 2 to expand laterally to adapt to soles of different widths.

[0037] At the same time, a screw rod 2 514 is rotatably installed on the outer side of the screw rod 1 511, and a wedge-shaped top block 1 515 is threadedly installed on the screw rod 2 514. An inclined guide groove 2 516 matching the wedge-shaped top block 1 515 is provided on the inner side of the instep shoe last shell 4. When the screw rod 2 514 rotates, the wedge-shaped top block 1 515 will push the instep shoe last shell 4 to expand it, thereby adjusting the height of the shoe body to meet the wearing needs of different users.

[0038] The extension component 52 is arranged at the rear end of the hollow shoe body 1 and is tightly connected to the heel last shell 3. By rotating the screw rod 3 521 installed at the rear end of the hollow shoe body 1, the wedge-shaped top block 2 522 will move along the thread of the screw rod 3 521. On the inner side of the heel last shell 3, there is an inclined guide groove 3 523 that cooperates with the wedge-shaped top block 2 522. When the screw rod 3 521 rotates, the wedge-shaped top block 2 522 will push the heel last shell 3 to expand it, thereby adjusting the length of the shoe body to ensure that the shoe fits the user's foot perfectly.

[0039] The electric drive unit 53 serves as the power source of the entire system and is electrically connected to the dual-form expansion component 51 and the extension component 52. It includes a drive motor 531 for controlling the expansion of the heel last shell 3 and a dual drive unit 532 for respectively controlling the expansion of the instep last shell 4 and the sole last shell 2. The drive motor 531 is powered by a built-in power supply and is fixed in the hollow shoe body 1. Its drive shaft is tightly and fixedly connected to the screw three 521 to ensure the stable operation of the extension component 52.

[0040] The dual-drive unit 532 includes a through-axis linear stepper motor 533 fixed in the hollow shoe body 1, which is also powered by a built-in power supply. A tooth groove 534 is carefully opened at the end of the screw 511 close to the through-axis linear stepper motor 533, and a cavity 535 with an inner diameter larger than the inner diameter of the tooth groove 534 is also opened inside the screw 511. A moving rod 536 slides through the driving shaft of the through-axis linear stepper motor 533, which passes through the tooth groove 534 and the cavity 535, and a gear 537 engaged with the tooth groove 534 is installed on the moving rod 536.

[0041] At the same time, a gear 2 538 with an outer diameter larger than that of gear 1 537 is fixed on the moving rod 536. A tooth groove 2 539 matching with gear 2 538 is also provided at the end of the screw rod 514, and the moving rod 536 passes through it. In order to switch the engagement state between gear 1 537 and gear 2 538 and tooth groove 1 534 and tooth groove 2 539, a pushing member 54 is also provided in the hollow shoe body 1.

[0042] The cavity 535 is located on a side of the tooth groove 1 534 away from the through-shaft linear stepping motor 533 , and the gear 2 538 is located on a side of the gear 1 537 close to the through-shaft linear stepping motor 533 ;

[0043] The pushing member 54 includes a pushing rod 541 slidably mounted on the hollow shoe body 1. The pushing rod 541 is located on the side of the gear 1 537 away from the cavity 535, and the bottom end is in contact with the moving rod 536. The bottom end of the pushing rod 541 is chamfered. When the pushing rod 541 is pressed down, the moving rod 536 is pushed to move, so as to drive the gear 1 537 to disengage from the tooth groove 1 534, and the gear 2 538 to engage with the tooth groove 2 539. A compression spring 542 is also sleeved on the moving rod 536, one end of the compression spring 542 abuts against the moving rod 536, and the other end of the compression spring 542 is rotatably abutted against the inner wall of the cavity 535.

[0044] Firstly, the design of cavity 535 is not only to accommodate the moving rod 536 and the compression spring 542, but more importantly, it serves as a buffer area between gear 1 537 and the moving rod 536. When the moving rod 536 moves under the action of the push member 54, cavity 535 allows gear 1 537 to have enough space to move to ensure smooth separation from tooth groove 1 534. At the same time, the existence of cavity 535 also ensures that the moving rod 536 can be quickly reset under the action of the compression spring 542, so that gear 1 537 can mesh with tooth groove 1 534 again.

[0045] The design of gear two 538 fully considers the switching requirements between it and gear one 537. Since the outer diameter of gear two 538 is larger than that of gear one 537, during the movement of the moving rod 536, gear two 538 can more easily engage with tooth groove two 539. This design not only improves the reliability of switching, but also makes the operation smoother.

[0046] The push piece 54 is a key component for switching gears, and its design has also been carefully considered. The chamfering of the push rod 541 makes it easier to push the moving rod 536 during the downward pressing process, thereby ensuring the smooth disengagement of the gear 1 537 and the tooth groove 1 534. At the same time, the sliding installation design of the push rod 541 allows the user to operate it easily without the need for additional tools or complicated steps.

[0047] The introduction of the compression spring 542 provides the system with an automatic reset function. When the push rod 541 is released, the elastic force of the compression spring 542 will quickly push the moving rod 536 to reset, so that the gear 1 537 is engaged with the tooth groove 1 534 again. This design not only improves the reliability of the system, but also makes it more convenient and quick for users to use it.

[0048] In addition, in order to further improve the stability and reliability of the system, some auxiliary components can be set inside the hollow shoe body 1. For example, a guide groove or a guide block can be set on the sliding path of the moving rod 536 to ensure the stability and accuracy of the moving rod 536 during the movement. At the same time, a limit block or a limit groove can be set on the sliding path of the top rod 541 to prevent the top rod 541 from excessive movement or derailment during operation. The core protection content of this application is not involved here, so it is not drawn or outlined in detail in the figure.
