Description

Technical Field

[0001] This utility model relates to the field of seedling cultivation technology, and in particular to a headrest structure for an aircraft simulator seat. Background Technology

[0002] In the field of modern aviation simulation training, aircraft simulators are key equipment for pilot training, and the design of their headrests directly affects the comfort and safety of pilots during simulated flight. With the continuous advancement of aviation technology and the increasing demands of pilot training, traditional aircraft simulator seat headrest structures are no longer sufficient to meet diverse training needs. In particular, existing headrest designs often have many shortcomings in terms of adjustability and comfort.

[0003] For example, consider a car headrest disclosed in prior art document CN110861554B. While this headrest structure takes user experience into account to some extent, it still has significant shortcomings in height adjustment. Specifically, this car headrest lacks an effective adjustment mechanism, preventing users from flexibly adjusting its height according to their individual height, posture habits, or the needs of simulated flight scenarios. This fixed design not only limits the headrest's applicability but may also cause unnecessary pressure on the pilot's neck and head, affecting training effectiveness and even posing safety hazards.

[0004] Furthermore, as flight simulation training scenarios become increasingly complex, pilots may need to frequently change headrests to adapt to different training tasks during simulated flights. However, the headrest structure in the comparative document does not take into account the ease of replacement of the headrest cushion, making headrest maintenance and upgrades cumbersome and costly.

[0042] In order to achieve a stable fit between the headrest cushion 1 and the inner lining plate 201, in this embodiment, the bottom of the headrest cushion 1 is provided with an inner lining groove 2011 that cooperates with the inner lining plate 201. This design ensures a tight fit between the headrest cushion 1 and the inner lining plate 201, enhances the overall stability of the headrest, reduces shaking and displacement during use, and improves the user experience.

[0043] To achieve flexible adjustment and locking of the headrest cushion 1 height, in this embodiment: the locking component 203 includes a positioning sleeve 2031 and a locking sleeve 2032 slidably sleeved on the positioning rod 202, and the top of the positioning sleeve 2031 and the bottom of the locking sleeve 2032 are detachable. A locking component 2033 for positioning the locking sleeve 2032 is installed on the side of the locking sleeve 2032. This design allows the height of the headrest to be flexibly adjusted according to user needs, and a stable lock is achieved through the locking component 2033, ensuring that the headrest remains stable at the adjusted height position, thus improving the safety and comfort of use.

[0044] To enhance the positioning accuracy between the positioning sleeve 2031 and the locking sleeve 2032 and the positioning rod 202, in this embodiment: positioning protrusions 20311 are fixedly connected to the inner walls of both the positioning sleeve 2031 and the locking sleeve 2032, and a positioning groove 20312 matching the positioning protrusion 20311 is provided on the positioning rod 202 at the position corresponding to the positioning protrusion 20311. Through the cooperative design of the positioning protrusion 20311 and the positioning groove 20312, the rotation and offset of the sleeve on the rod are effectively prevented, and the accuracy and stability of the headrest adjustment are improved.

[0045] To enable quick connection and disassembly between the positioning sleeve 2031 and the locking sleeve 2032, in this embodiment: a threaded sleeve 20321 is fixedly connected to the bottom of the locking sleeve 2032, and a threaded ring 20322 matching the threaded sleeve 20321 is fixedly connected to the top of the positioning sleeve 2031. The threaded connection design makes the connection and disassembly between the positioning sleeve 2031 and the locking sleeve 2032 simple and quick, allowing users to adjust the headrest height as needed, thus improving the adaptability and practicality of the headrest.

[0046] To achieve a secure lock on the positioning rod 202, in this embodiment, the locking assembly 2033 includes a receiving groove 20331 formed on the inner wall of the locking sleeve 2032.
