Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a protective structure, a vehicle seat, and a vehicle. Background Technology

[0002] If items are placed on the seats while the vehicle is in motion, they may fall off due to inertia during sudden braking or sharp turns, causing damage. In particular, if the items placed on the seats are heavy or have sharp edges, they can easily cause injury to the vehicle or passengers during sudden braking or sharp turns.

[0003] To address the above issues, some vehicle seats are equipped with rollers and protective curtains at the bottom. When items are placed on the seat, the curtain is released from the roller to prevent them from sliding forward. When not in use, the curtain is rolled up onto the roller. However, in existing technology, the roller is in a free-rotating state, making it difficult to control its rotation speed and number of rotations. This makes it difficult to control the speed and length of the curtain's roll-up / release, resulting in a poor user experience. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a protective structure, a vehicle seat, and a vehicle, which, by setting a limiting part to control the rate and length of the release and / or retraction of the protective part, allows the length of the release and / or retraction of the protective part to be adjusted according to the size of the items placed on the seat, thereby achieving better protection, improving safety, and enhancing the user experience.

[0045] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0046] It should be noted that, unless otherwise specified, the embodiments of the present invention and the technical features thereof can be combined with each other.

[0047] This invention provides a protective structure 100 applied to a vehicle seat. Specifically, as shown in the embodiment of the invention... Figure 1 As shown, the protective structure 100 may include: a protective part 101, a first connecting part 102, a second connecting part 103, and a limiting part 104. The first connecting part 102 is fixed to the bottom of the vehicle seat. One end of the protective part 101 is fixed to the first connecting part 102, and the other end is fixedly connected to the second connecting part 103. The second connecting part 103 is detachably connected to the backrest of the vehicle seat, and the limiting part 104 is installed on the first connecting part 102. During the installation of the second connecting part 103 on the backrest, the first connecting part 102 releases the protective part 101, and the second connecting part 103 drives the protective part 101 to unfold from the front side of the vehicle seat toward the backrest of the vehicle seat. After the second connecting part 103 is detached from the backrest, the first connecting part 102 retracts the protective part 101. The limiting part 104 is used to limit the rate or length at which the protective part 101 is released or retracted.

[0048] Figure 1The diagram shows the protective structure with the protective unit 101 deployed, including three seats, each with a protective structure installed. In an optional embodiment of the invention, multiple seats may also be equipped with one protective structure. This embodiment of the invention will be described with respect to the case where one protective structure is installed on one seat.

[0049] The width direction of the protective part 101 ( Figure 1 The direction indicated by the dotted line with arrows is parallel to the width direction of the vehicle seat. One end of the protective part 101 is connected to the bottom of the seat via the first connecting part 102, and the other end is connected to the seat back. Preferably, the other end of the protective part 101 is connected to the headrest support at the upper part of the seat back. When the protective part 101 is deployed, it can be used to prevent items placed on the seat from falling off, especially during sudden braking or sharp turns while the vehicle is in motion, preventing items from being thrown forward, to the left, or to the right due to inertia. In addition to preventing items from falling off, the deployed protective part 101 also prevents items on the seat from shaking, which is a real need in people's daily lives.

[0050] During the use of this protective structure, it was found that the number of items placed on the vehicle seats varied, sometimes more and sometimes less. However, the existing protective structure always fully extends the protective section 101 when it is in the extended state and fully retracts it when it is in the retracted state. This means that the extension or retraction length of the protective section 101 cannot be adjusted according to the size of the items on the seat, and the space for placing items on the seat cannot be flexibly adjusted, making it impossible to confine the items to a suitable space. As a result, when there are few items placed on the seat, the protective section 101 cannot provide adequate protection for the items.

[0051] To solve the above problems, refer to Figure 1 and Figure 3 As shown, this embodiment includes a limiting part 104, which is installed on the first connecting part 102 to limit the length of the protective part 101 released and / or retracted by the first connecting part 102. This allows control over the length of the protective part 101 released or retracted based on the volume of the item placed on the seat. For example, when the volume of the item placed on the seat is V, the protective part 101 is released to a length of L, and the space enclosed by the seat and the protective part is just enough to hold the item. When the volume of the item placed on the seat is 2V, the protective part 101 is released to a length of 1.5L, and the space enclosed by the seat and the protective part is just enough to secure the item.

[0052] For example, if the initial volume of the item placed on the seat is 2V, and the extended length of the protective unit 101 is 1.5L, and the item on the seat is halved midway through the process, resulting in a current volume of V, then the length of the protective unit 101 can be retracted by 0.5L. This reduces the space enclosed by the seat and the protective unit, limiting the movable space of the item and allowing the protective unit 101 to provide better protection. It's understandable that 1.5L is less than or equal to the fully extended length of the protective unit.

[0053] The limiting part 104 can be used to lock the protective part 101. After the user confirms the length of the protective part's release or retraction, the limiting part 104 locks the protective part. When the protective part 101 is locked by the limiting part 104, its length cannot be extended or shortened. The limiting part 104 can also limit the rate at which the protective part 101 is released or retracted, preventing the protective part 101 from being released or retracted too far. This makes it easier to control the length of the protective part's release or retraction, avoiding situations where the released length is too long before retraction or vice versa, thus improving operational efficiency.

[0054] This embodiment, by setting a limiting part 104, makes the length of the release or retraction of the protective part 101 adjustable, which can play a better protective role for items on the vehicle seat, achieve a better protective effect, improve safety, and enhance the user experience.

[0055] Additionally, when the protective unit 101 is not needed, such as when no items are placed on the vehicle seat, the protective unit 101 can be stored under the seat. The stored protective unit 101 is as follows: Figure 2 As shown. Understandably, in order to ensure that the protective structure in its stowed state does not affect the passenger's riding experience, the stowed protective structure can be located in a relatively concealed position under the seat.

[0056] The protective part 101 is made of a soft and highly resilient material, such as a high-strength woven fabric or textile. The protective part 101 can be stored by stacking it under the seat. For a more aesthetically pleasing arrangement, a storage box can be installed under the seat to hold the stacked protective parts 101. Alternatively, the protective part 101 can be rolled up on a swivel.

[0057] To achieve the technical effects of the above embodiments, in an optional embodiment of the present invention, the first connecting portion 102 is a rotating shaft, the axis of which is parallel to the width direction of the vehicle seat. The axis direction of the rotating shaft can be referenced... Figure 1 The dotted line with an arrow indicates the direction; the installation position of the shaft can be referenced. Figure 1 and Figure 2 The positional relationship between the shaded area and the vehicle seats; additionally, it can be... Figure 2 The shaded area in the image represents the state after the protective part 101 is rolled up on the rotating shaft.

[0058] Furthermore, in order to achieve the technical effects of the above embodiments, in an optional embodiment of the present invention, the limiting part 104 can be a friction-type speed limiter; the friction-type speed limiter includes a housing 1041, a friction plate 1042, and a pressure regulating component 1043. The friction plate 1042 is disposed inside the housing 1041, and the pressure regulating component 1043 is partially disposed inside the housing 1041; the housing 1041 is mounted on the end of the rotating shaft, and the friction plate 1042 is in contact with the rotating shaft; the pressure regulating component 1043 is used to adjust the contact pressure between the friction plate 1042 and the rotating shaft to change the friction force between the friction plate 1042 and the rotating shaft.

[0059] Figure 3 The diagram shows the limiting part 104 installed on the rotating shaft. Figure 4 This is a schematic diagram of the main structure of the limiting part 104. The pressure regulating component 1043 includes a spring and an adjusting knob. The two ends of the spring are connected to two friction plates 1042, and the adjusting knob is connected to the spring. Rotating the adjusting knob forward or backward causes the spring to extend or retract. Extending the spring increases the contact pressure between the friction plate 1042 and the rotating shaft, while retracting the spring decreases the contact pressure. By adjusting the pressure regulating component 1043, i.e., by rotating the adjusting knob, the contact pressure between the friction plate 1042 and the rotating shaft is controlled. The greater the contact pressure, the greater the friction between the friction plate 1042 and the rotating shaft. When the friction exceeds a certain threshold, the protective part 101 is locked, preventing it from extending or retracting. When it is not necessary to lock the protective part 101 and only the release or retraction rate of the protective part 101 needs to be controlled, the contact pressure between the friction plate 1042 and the rotating shaft is adjusted to a suitable value by adjusting the pressure adjustment component 1043, so that the friction force between the friction plate 1042 and the rotating shaft reaches a certain value, so that the protective part 101 is not locked and its release or retraction speed is not too fast, thereby ensuring the stability of the release or retraction of the protective part 101 and making it easier to control the length of the release or retraction of the protective part 101.

[0060] Furthermore, in order to ensure that the protective part 101 does not shift or tilt when released, or that the protective part 101 retracts precisely to the designated storage position when retracted, thus saving the user the trouble of manually adjusting its position, in an optional embodiment of the present invention, the protective structure further includes: limiting grooves installed at both ends of the first connecting part 102, the edge of the protective part 101 being embedded in the limiting grooves; the limiting grooves are used to guide the edge of the protective part 101 to extend or retract along the edge of the first connecting part 102.

[0061] This embodiment uses limiting grooves to ensure that both ends of the protective part 101 move along the corresponding limiting grooves when it is released or retracted. This prevents the protective part 101 from shifting or tilting when released due to inconsistent movement speed or position on both sides, which would make it difficult to fix the protective part 101 to the seat back or prevent the retracted protective part 101 from entering the storage position, requiring manual adjustment by the user. This embodiment improves the ease of operation and efficiency of the protective structure.

[0062] To further improve the operational convenience of the protective structure, a drive component can be installed on the rotating shaft so that when the drive component is triggered by an external force, it automatically drives the rotating shaft to rotate, thereby realizing the winding or unwinding of the protective part 101. In an optional embodiment of the present invention, the protective structure further includes: a drive component disposed at one end of the rotating shaft, which drives the rotating shaft to rotate forward or backward under the trigger of an external force, so that the protective part 101 is wound onto or released from the rotating shaft.

[0063] The driving component can be a motor, which is connected to one end of the rotating shaft. When the motor is started by the user, the motor rotates forward or backward, thereby driving the rotating shaft to rotate forward or backward, which in turn causes the protective part 101 to be released or wound up.

[0064] This embodiment avoids the need for users to apply force to drive the shaft rotation by setting up a driving component, thereby reducing manual operation and improving ease of operation.

[0065] When the protective structure is required for safety protection, in order to facilitate fixing the other end of the protective part 101 to the seat back, the second connecting part 103 can be set as a hook and hung on the headrest support column on the seat back.

[0066] In an optional embodiment of the present invention, the second connecting part 103 is a hook, and the opening size of the hook is adjustable.

[0067] To facilitate hanging the hooks on the headrest support column, the hook opening is designed to be adjustable. Before hanging the hooks on the headrest support column, the hook opening is widened to make it easier to hang them on the headrest support column. After hanging the hooks on the headrest support column, the hook opening is narrowed to secure the hooks to the headrest support column and prevent the hooks from falling off. Figure 5 The diagram shows the connection between the hook and the headrest support column.

[0068] This embodiment improves the convenience of fixing the other end of the protective part to the seat back by setting a hook and an adjustable hook opening, providing users with convenient operation and improving user experience.

[0069] This invention provides a vehicle seat 200, including: a seat body 201 and a protective structure 100 as described in any of the above embodiments, with reference to... Figure 1 and Figure 2 As shown.

[0070] To facilitate the installation of protective structures on the seat body, the vehicle seat also includes two support members 202 fixed to the bottom side of the seat body 201, such as... Figure 6 As shown, the two support members 202 are along the width direction of the seat body 201 (e.g., Figure 6 (The direction indicated by the dashed line with the arrow) is set at intervals; the first connecting part 102 is installed between the two support members 202 and the two ends of the first connecting part 102 are rotatably connected to their corresponding support members 202 respectively.

[0071] In an optional embodiment of the present invention, when the protective part 101 of the protective structure is in the deployed state, such as... Figure 7 As shown, the second connecting part 103 of the protective structure is connected to the headrest support column of the seat body 201 where the protective structure is located, or, as... Figure 8 As shown, when the protective structure is installed on the rear seat body 201, the second connecting part 103 of the protective structure is connected to the headrest support column of the front seat inside the vehicle. When the protective part 101 is in the retracted state, the second connecting part 103 is connected to the bottom of the seat body 201 where the protective structure is located. The retracted state of the protective part is shown in the reference diagram. Figure 2 .

[0072] Specifically, when there are fewer items to place on the vehicle seats, meaning less space is needed in the rear seats, refer to... Figure 7 The other end of the protective part 101 can be connected to the headrest support column of the seat on which the protective structure is installed. When there are many items to be placed on the vehicle seats, i.e., when a large amount of space needs to be reserved in the rear seats, this can be referred to... Figure 8The other end of the protective part 101 is connected to the headrest support column of the front seat. This embodiment enables flexible adjustment of the protective part, allowing for flexible use of the vehicle seat to place items while ensuring safety.

[0073] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
