Description

Technical Field

[0001] This utility model relates to ski boots, specifically a ski boot with a multi-dimensional locking structure. Background Technology

[0002] Ski boots are primarily designed for use with skis, and the two can be detached to allow for easy removal of the skis when needed.

[0003] Whether at outdoor ski resorts or indoor ski facilities, the ambient temperature is usually very low, which significantly reduces finger dexterity. Therefore, ski boots generally need to be put on indoors beforehand. Furthermore, ski boots cannot typically be secured with conventional laces or nylon straps. Existing designs—whether using laces or nylon straps—are designed to firmly fix the ski boots to the feet, preventing risks caused by an ill-fitting boot. However, this also results in a relatively restrictive feeling when wearing them. How to effectively alleviate this restriction and improve wearing comfort is a crucial issue that urgently needs to be addressed! Utility Model Content

[0004] The purpose of this invention is to provide a ski boot with a multi-dimensional locking structure to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ski boot with a multi-dimensional locking structure, comprising a boot body and a sole, wherein the boot body is divided into an outer fabric and an inner fabric according to its structure, and a filling part is provided between the two;

[0006] The outer side of the interior fabric is provided with symmetrically distributed thread buckle groups, and tie straps are crisscrossed on the thread buckle groups;

[0007] The boot body is divided into the lower leg and the instep according to the corresponding position of the human foot, and the two sets of straps are distributed on the lower leg and the instep;

[0008] It also includes two winding reels driven by a micro motor, the two winding reels rotating in opposite directions, and the two ends of the strap are respectively wrapped around the two winding reels.

[0009] Preferably, the sole is provided with a first L-shaped elastic plate distributed at the heel, the first L-shaped elastic plate including a horizontal part and a vertical part, and the two maintain a predetermined angle;

[0010] The vertical portion is located on the sole, while the horizontal portion is located between the filling portion and the interior fabric and is fixed to the interior fabric.

[0011] Preferably, the horizontal part is provided with a soft silicone rubber support for the rear feet.

[0012] Preferably, the sole is provided with a second L-shaped elastic plate distributed in the center of the foot. The second L-shaped elastic plate includes a horizontal arched part and an arc-shaped covering part on the instep, with one end of the two connected and distributed on one side of the ski boot, maintaining a predetermined included angle.

[0013] The threading buckle assembly is fixed to the instep arc-shaped cover and the horizontal arch.

[0014] Preferably, the device also includes an air pump fixed to the interior fabric, and an inflatable air cushion is fixedly provided on the inner side of the foot arched cover and the inner side of the interior fabric where the lower leg strap is located.

[0015] Preferably, a polyester fleece lining is also included, which is disposed inside the interior fabric and covers the inflatable air cushion.

[0016] Preferably, the filling can be cotton filling or duck down filling.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] See Figure 1-6 This embodiment provides a ski boot with a multi-dimensional locking structure, including a boot body 1 and a sole 2 fixedly connected to its bottom. The boot body 1 includes, from the outside to the inside, an outer fabric 11, a filling part 15, and an inner fabric 12. The outer fabric 11 is usually made of abrasion-resistant and waterproof fabric, while the inner fabric 12 is made of a skin-friendly and soft material. The cavity formed between the two is the filling part 15, which can be filled with warm materials such as cotton or down.

[0032] To achieve intelligent locking, two sets of threaded buckle groups 3 are symmetrically arranged on the outer side of the inner lining fabric 12, corresponding to the lower leg 13 and the instep 14 areas of the human body, respectively. The straps 4 are crisscrossed and threaded through these threaded buckle groups 3 to form a wrap around the lower leg and instep.

[0033] The locking drive mechanism includes a micro motor 5 and two winding reels 51 driven by it. The key design feature is that the two winding reels 51 rotate in opposite directions. The output end of the micro motor 5 is directly and fixedly connected to one of the winding reels 51, and simultaneously engaged with the other winding reel 51 via a set of transmission gears 52, thus enabling one motor to synchronously drive the two winding reels to rotate in opposite directions. The two ends of the strap 4 are respectively wound and fixed in opposite directions within the two winding reels 51. When the micro motor 5 rotates in the forward direction, one winding reel winds up the strap, while the other simultaneously releases, tightening the strap 4 and applying pressure to the lower leg 13 and foot 14; when rotating in the reverse direction, the strap is loosened.

[0034] To achieve comfort control, multiple pressure sensors (not shown in the figure) are integrated on the inner fabric 12 below the path of the strap 4 on the lower leg 13 and foot 14. These sensors detect the pressure value of the strap on the foot in real time and transmit the signal to the control circuit. The control circuit (usually located in the circuit compartment described in a later embodiment) has a preset comfort pressure threshold. When the detected pressure exceeds the threshold, the micro motor 5 is automatically controlled to finely loosen the strap; when the pressure is below the threshold, the strap is finely tightened, thus forming a closed-loop "detection-feedback-control" system to dynamically maintain the optimal restraint force and effectively alleviate the tightness of wearing for a long time.

[0035] Example 2

[0036] Based on Example 1, this example further introduces a mechanically assisted deployment structure to significantly improve the donning and doffing experience.

[0037] See Figures 2-4 As shown, a first L-shaped elastic plate 21 is embedded inside the heel area of ​​the sole 2. This plate is made of a material with good elastic recovery properties (such as spring steel or high-performance engineering plastics), and its structure includes an integrally molded horizontal portion 211 and a vertical portion 212, which are L-shaped and maintain an acute angle (i.e., less than 90 degrees by default). The vertical portion 212 is fixedly embedded in the heel structure of the sole 2, while the horizontal portion 211 extends upward and inserts between the filling portion 15 of the boot body 1 and the inner lining fabric 12, and is finally fixed to the inner lining fabric 12 at the position corresponding to the back of the calf. To further improve the foot feel, a soft silicone heel support portion 6 is also fitted on the side of the horizontal portion 211 that contacts the foot.

[0038] When the strap 4 is released (i.e., in the relaxed state), the first L-shaped elastic plate 21 is no longer constrained inward by the strap. Due to its own elasticity, the angle between the horizontal part 211 and the vertical part 212 tends to increase, thereby generating a force that pushes the inner fabric 12 outward, actively opening the boot body of the lower leg 13, making it easier for the user to insert or withdraw their foot.

[0039] Furthermore, a second L-shaped elastic plate 22 is embedded inside the arch area of ​​the sole 2. This plate is also made of elastic material and has a more unique structure, including a horizontal arch 221 and an instep curved cover 222. The two are connected at one end, forming an arc-shaped spring extending from one side (usually the inside) of the ski boot towards the instep. The horizontal arch 221 mainly supports the arch of the foot, while the instep curved cover 222 curves upward to cover part of the instep. A portion of the aforementioned instep area threaded fastener group 3 can be directly fixed to the instep curved cover 222.

[0040] When the strap 4 is loosened, the second L-shaped elastic plate 22 returns to its default shape, which increases the space between the horizontal arch 221 and the instep arc cover 222, thereby opening up the shoe body of the instep 14. In coordination with the opening action of the heel, the entire foot entrance is expanded, which greatly facilitates putting on and taking off the shoes.

[0041] Example 3

[0042] This embodiment, based on Embodiment 2, integrates an air cushioning system and a central control module, achieving superior comfort and user interaction. Inflatable air cushions 71 are fixedly installed on the inner side of the curved instep cover 222 and on the inner side of the interior fabric 12 corresponding to the strap 4 path on the lower leg 13. A miniature air pump 7 is fixedly installed on the interior fabric 12 and connected to these inflatable air cushions 71 via a miniature air passage. To protect the air cushions and improve tactile feel, a soft polyester fleece lining 8 is also covered on the surface of all inflatable air cushions 71.

[0043] Secondly, a sealed circuit compartment is fixedly installed in a prominent position on the outer fabric 11 (such as the outside of the lower leg) using a rubber mounting pad 9. The circuit compartment integrates a control motherboard, a rechargeable battery, etc. A Type-C charging module 100 and a power switch 101 are integrated on the surface of the circuit compartment. The Type-C charging module 100 is used to charge the battery inside the compartment, which powers the micro motor 5, the air pump 7, the pressure sensor, and the control circuitry.

[0044] Working principle:

[0045] When the user presses the power switch 101, the system starts. The control circuit first drives the air pump 7 to inflate the air cushion 71 with an appropriate amount of air, causing it to slightly inflate and pre-form a soft cushioning layer between the foot and the strap. This process continues for a predetermined time (e.g., 2-3 seconds), after which the air pump 7 automatically stops. Immediately afterwards, the micro motor 5 starts running, driving the winding reel 51 to tighten the strap 4. Due to the cushioning effect of the air cushion, the initial pressure during the tightening process is significantly reduced. After tightening, the system switches to a dynamic adjustment mode controlled by pressure sensor feedback, as described in Example 1, continuously fine-tuning to maintain comfortable pressure.

[0046] When it is time to remove the shoes, the user presses and holds the power switch 101, and the micro motor 5 will completely release the straps 4. At the same time, under the elastic restoring force of the first L-shaped elastic plate 21 and the second L-shaped elastic plate 22, the lower leg 13 and the instep 14 of the ski boot are actively stretched open. Combined with the support of the air cushion, the action of removing the shoes becomes very easy.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
