Detailed Implementation

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Reference Figure 1 The diagram shows a first-view structural diagram of the elbow pillow box ventilation cover control structure according to an embodiment of the present invention. (Refer to...) Figure 2 This diagram illustrates a second-view structural view of the elbow rest compartment ventilation cover control structure according to an embodiment of the present invention. In this embodiment, the elbow rest compartment ventilation cover control mechanism is used to control the ventilation hole 800 below the elbow rest compartment to control the ventilation of the elbow rest compartment. Specifically, the elbow rest compartment ventilation cover control structure of this embodiment includes the following components:

[0042] Switch assembly 100 is disposed on the top of the elbow rest box;

[0043] The drive component 200 has one end connected to one end of the switch component 100;

[0044] A ventilation cover 300 has one end connected to the other end of the drive assembly 200, and one side of it contacts the ventilation hole 800 at the bottom of the elbow rest box, for controlling the opening of the ventilation hole 800.

[0045] The baffle assembly 400 has one side connected to the inner wall of the elbow pillow box to form a receiving cavity, and the drive assembly 200 and the ventilation cover 300 are located in the receiving cavity;

[0046] When the switch assembly 100 moves, the drive assembly 200 drives the ventilation cover 300 to move in the receiving cavity.

[0047] In this embodiment of the invention, the control structure of the elbow rest box ventilation cover 300 can be composed of a switch assembly 100, a drive assembly 200, a ventilation cover 300, and a baffle assembly 400. The switch assembly 100 is located on the top of the elbow rest box, meaning the user can control it from within the elbow rest box. The switch assembly 100 can be a push-button switch, used to drive the switch assembly 100 to move through a pressing operation. The switch assembly 100 can also be a slide switch, with an inclined surface below it, driving the movement of the structure through contact with the inclined surface. Figure 1 As shown, the switch assembly 100 is a push-button switch.

[0048] One end of the drive assembly 200 is connected to one end of the switch assembly 100, and the other end is connected to the ventilation cover 300. When the user presses the switch assembly 100, the movement of the switch assembly 100 drives the drive assembly 200 to move, and the drive assembly 200 moves accordingly and transmits the movement to the ventilation cover 300.

[0049] One side of the ventilation cover 300 contacts the ventilation hole 800 at the bottom of the armrest box. When the ventilation cover 300 completely covers the ventilation hole 800, the opening degree of the ventilation hole 800 is zero, i.e., it is in the closed state. When the ventilation cover 300 does not cover the ventilation hole 800, the opening degree of the ventilation hole 800 is fully open, i.e., it is in the fully open state. When the ventilation cover 300 partially covers the ventilation hole 800, the opening degree of the ventilation hole 800 is between 0 and 1, i.e., it is in the partially open state. When the drive assembly 200 moves, it drives the ventilation cover 300 to move, thereby causing the ventilation cover 300 to block or open the ventilation hole 800. Figure 1 As shown, when the drive component 200 moves the ventilation cover 300 upward, the ventilation hole 800 opens; conversely, when the drive component 200 moves the ventilation cover 300 downward, the ventilation hole 800 closes.

[0050] Furthermore, to prevent external objects from affecting the movement of the switch assembly 100, drive assembly 200, and ventilation cover 300, a baffle assembly 400 can be provided. One side of the baffle assembly 400 is connected to the inner wall of the elbow rest box, and the side of the baffle assembly 400 and the inner wall of the elbow rest box form a receiving cavity, in which the switch assembly 100, drive assembly 200, and ventilation cover 300 are all disposed. By blocking external objects with the baffle assembly 400, the switch assembly 100, drive assembly 200, and ventilation cover 300 move within the receiving cavity formed by the baffle assembly 400 and the inner wall of the elbow rest box.

[0051] The control structure of the elbow rest box ventilation cover 300 of the present invention includes a switch assembly 100 disposed on the top of the elbow rest box, which can be conveniently controlled by the user. Then, the movement of the switch assembly 100 moves towards the bottom of the elbow rest box, thereby driving the drive assembly 200 and the ventilation cover 300 to move in sequence, thereby controlling the opening of the ventilation hole 800. This allows the user to control the opening and closing of the ventilation hole 800 simply by operating the switch assembly 100, making operation convenient. Furthermore, the baffle assembly 400 is connected to the inner wall of the elbow rest box to form a receiving cavity. The drive assembly 200 and the ventilation cover 300 are located in this receiving cavity. That is, the drive assembly 200 and the ventilation cover 300 move within the receiving cavity. Even if there are no items placed inside the elbow rest box, it will not obstruct the movement of the drive assembly 200 and the ventilation cover 300, so that the opening and closing of the ventilation hole 800 of the ventilation cover 300 is not affected by the items placed inside the box.

[0052] In an optional embodiment of the present invention, the driving component 200 includes:

[0053] The switch linkage 210 has a flat end at one end, which is connected to the switch assembly 100, and an arc-shaped end at the other end;

[0054] A gear fixing component 220 is connected to the arc-shaped end, and a gear fixing shaft is provided on the surface of the gear fixing component 220;

[0055] Rotate gear 230, which is sleeved on the gear fixed shaft;

[0056] The rack 240 meshes with the rotating gear 230, and the rack 240 is fixedly connected to the ventilation cover 300.

[0057] In this embodiment of the invention, the drive assembly 200 may specifically include: a switch linkage 210, a gear fixing member 220, a rotating gear 230, and a rack 240.

[0058] One end of the switch linkage 210 is a flat section, and the other end is an arc-shaped end; the flat end is connected to the switch assembly 100, and when the switch assembly 100 is pressed, the switch linkage 210 slides downward accordingly.

[0059] The gear fixing member 220 is connected to the arc-shaped end of the switch linkage 210, and rotates around its own axis when the switch linkage 210 moves downward. The gear fixing member 220 is coded with a gear fixing shaft, the axis of which is the same as the axis of the gear fixing member 220. Furthermore, a connecting key may be provided on the gear fixing shaft, or the gear fixing shaft may be a key shaft.

[0060] The rotating gear 230 is sleeved on the fixed gear shaft. When the fixed gear shaft rotates, the rotating gear 230 rotates accordingly.

[0061] The rack 240 is fixedly connected to the ventilation cover 300. The teeth on the rack 240 mesh with the rotating gear 230. When the rotating gear 230 rotates, it drives the rack 240 to move up and down, thereby driving the ventilation cover 300 to move up and down to adjust the opening of the ventilation hole 800.

[0062] In an optional embodiment of the present invention, the baffle assembly 400 includes:

[0063] The first baffle 410 is fixedly connected to the upper inner wall 910 of the elbow pillow box and is used to block foreign objects from entering the switch linkage 210.

[0064] The second baffle 420 is fixedly connected to the lower inner wall 920 of the elbow pillow box and is used to block foreign objects from entering the gear fixing member 220, the rotating gear 230, the rack 240 and the ventilation cover 300.

[0065] In this embodiment of the invention, the baffle assembly 400 may consist of two parts: a first baffle 410 and a second baffle 420. The first baffle 410 is disposed on the upper inner wall 910 of the elbow rest box and is fixedly connected to the upper inner wall 910 of the elbow rest box. The first baffle 410 and the upper inner wall 910 of the elbow rest box form a receiving cavity. The switch linkage 210 is located in the receiving cavity and moves within the receiving cavity. The first baffle 410 prevents foreign objects from entering the switch linkage 210 and affecting the movement of the switch linkage 210.

[0066] The second baffle 420 is fixedly connected to the lower inner wall 920 of the elbow rest box. The second baffle 420 and the lower inner wall 920 of the elbow rest box form another receiving cavity. The gear fixing member 220, the rotating gear 230, the rack 240 and the ventilation cover 300 are located in the receiving cavity and move in the receiving cavity. The first baffle 410 blocks foreign objects from entering the gear fixing member 220, the rotating gear 230, the rack 240 and the ventilation cover 300, and blocks the movement of the gear fixing member 220, the rotating gear 230, the rack 240 and the ventilation cover 300.

[0067] Reference Figure 3 In an optional embodiment of the present invention, the inner side of the first baffle 410 is provided with damping engagement teeth, and the control structure of the elbow pillow box ventilation cover 300 further includes:

[0068] A damping gear 500 is mounted on the switch linkage 210, and the damping gear 500 meshes with the damping engagement teeth.

[0069] In this embodiment of the invention, a damping meshing tooth is provided on the inner side of the first baffle 410. The meshing tooth can be distributed along the vertical direction of the first baffle 410. The damping gear 500 is installed on the switch linkage 210. Specifically, the damping gear 500 is fixed on the switch linkage 210. The damping gear 500 meshes with the damping meshing tooth and provides a certain damping force when the switch linkage 210 moves, so that the user feels the damping when pressing the switch assembly 100, thereby preventing the switch assembly 100 from being operated violently and protecting the switch assembly 100.

[0070] In an optional embodiment of the present invention, the first baffle 410 is provided with a groove, and the first baffle 410 is welded to the upper inner wall 910 of the elbow pillow box through the groove; the second baffle 420 is welded to the lower inner wall 920 of the elbow pillow box.

[0071] In this embodiment of the invention, the first baffle 410 is provided with a plurality of grooves, which can be symmetrically distributed along the central axis of the first baffle 410. The first baffle 410 is combined and overlapped with the upper inner wall of the elbow pillow box through the grooves, and weld points are formed on the grooves so that the first baffle 410 can be stably fixed to the upper inner wall 910 of the elbow pillow box.

[0072] The second baffle 420 is welded to the inner wall 920 below the elbow rest box so that the second baffle 420 can be stably fixed to the inner wall 920 below the elbow rest box.

[0073] In an optional embodiment of the present invention, the control structure of the elbow pillow box ventilation cover 300 further includes:

[0074] A rack and pinion plate 600 is connected to the rack and pinion 240 and is used to press the rack and pinion 240 together.

[0075] In this embodiment of the invention, a rack and pinion plate 600 can also be provided on the inner wall of the elbow pillow box. The rack and pinion plate 600 is connected to the rack 240 and is used to press the rack 240 and guide and position the rack 240 so that it can move in an accurate direction to open or close the ventilation hole 800.

[0076] In an optional embodiment of the present invention, the control structure of the elbow pillow box ventilation cover 300 further includes:

[0077] The locking component 700 is connected to the driving component 200 and is used to lock the movement of the driving component 200 when it is in a locked state.

[0078] In this embodiment of the invention, a locking component 700 may also be provided. The locking component 700 is connected to the driving component 200. When the locking component 700 is in a locked state, it can lock the movement of the driving component 200, so that the driving component 200 is temporarily stationary and the opening of the ventilation hole 800 remains unchanged.

[0079] Furthermore, the locking assembly 700 has a recessed portion 710 at one end near the rack 240, and the rack 240 has a protruding portion 241 at one end near the locking assembly 700. In the locked state, the recessed portion 710 is connected to the protruding portion 241.

[0080] In this embodiment of the invention, the recess 710 is provided at one end of the locking assembly 700 near the rack 240, such as... Figure 1 As shown, the recessed portion 710 is located below the locking assembly 700. The protrusion 241 is located at the end of the rack 240 near the locking assembly 700, as shown... Figure 1As shown, the protrusion 241 is positioned above the rack 240. This allows the locking assembly 700 and the rack 240 to form a push-push structure. The locking assembly 700 and the rack 240 employ a single-time locking mechanism. Upon the first press, the rack is locked, and the recess 710 moves downward until it engages with the protrusion 241, placing the rack 240 and the locking assembly 700 in a locked state. Upon the second press, the rack is unlocked, and this cycle repeats. This allows the user to easily operate between the locked and unlocked states.

[0081] This invention utilizes a switch assembly located at the top of the elbow rest box, allowing for convenient user control. The movement of the switch assembly, moving towards the bottom of the elbow rest box, sequentially drives the drive assembly and the ventilation cover, thereby controlling the opening of the ventilation holes. This allows users to control the opening and closing of the ventilation holes simply by operating the switch assembly, making operation convenient. Furthermore, the baffle assembly connects to the inner wall of the elbow rest box, forming a receiving cavity. The drive assembly and ventilation cover are located within this cavity, meaning their movement is unimpeded even if items are placed inside the elbow rest box, ensuring the opening and closing of the ventilation holes are unaffected by the items inside. A locking assembly locks the ventilation holes after they are opened, allowing them to remain open for extended periods.

[0082] In this embodiment of the invention, an elbow rest box assembly is also disclosed, including a box body and an elbow rest box ventilation cover control structure as described above.

[0083] Ventilation openings are provided at the bottom of the enclosure;

[0084] The ventilation cover control structure of the elbow rest box is located inside the box and is used to control the opening degree of the ventilation opening.

[0085] The elbow rest box assembly consists of two parts: the box body and the elbow rest box assembly. A ventilation opening is located at the bottom of the box body; the ventilation cover control structure is located inside the box body. When the user operates the switch assembly on it, the drive assembly moves the ventilation cover, thereby controlling the opening degree of the ventilation opening.

[0086] The elbow rest box ventilation cover control structure, used to control the ventilation of the elbow rest box, includes:

[0105] Furthermore, the elbow rest box ventilation cover control structure also includes:

[0106] A locking component, connected to the driving component, is used to lock the movement of the driving component when it is in a locked state.

[0107] Users can easily control the system using a switch assembly. The movement of the switch assembly moves towards the bottom of the elbow rest box, sequentially driving the drive assembly and the ventilation cover to move, thereby controlling the opening of the ventilation holes. This allows users to control the opening and closing of the ventilation holes simply by operating the switch assembly, making operation convenient. Furthermore, the baffle assembly is connected to the inner wall of the elbow rest box to form a receiving cavity. The drive assembly and the ventilation cover are located in this receiving cavity, meaning that the movement of the drive assembly and the ventilation cover within the receiving cavity will not obstruct the movement of the drive assembly and the ventilation cover, even if there are no items inside the elbow rest box.
