Technical Field

[0001] This utility model relates to the field of headrest processing technology, and in particular to a headrest pressing device. Background Technology

[0002] A headrest is a device installed on the back of a seat to improve seating comfort and protect the safety of passengers. Early headrests were mainly designed to improve comfort, providing support for the head and relieving neck pressure during long drives or rides. With the development of automotive safety technology, headrests have become an important safety device, supporting the head and mitigating impact force in the event of a rear-end collision, preventing excessive backward tilting of the head and cervical spine injuries.

[0003] A search revealed a Chinese patent publication number, CN218453207U, which discloses an electrically controlled headrest pressing device. The device includes a processing table with a lower positioning base. The top surface of the lower positioning base is a curved surface with an upward convex shape for placing the outer panel of the headrest. The upper side of the outer panel of the headrest has an inner panel for fastening onto the outer panel of the headrest. Several fasteners are provided on the outer periphery of the outer panel of the headrest. This utility model allows the entire headrest pressing process to be completed on a processing table. The curved top surface of the lower positioning base effectively positions the outer headrest panel. The operation of the drive unit enables the upper positioning block to move in an orderly manner, and the movement of the upper positioning block can evenly press the inner headrest panel. The operation of the telescopic cylinder can press the slot of the inner headrest panel and the fastener of the outer headrest panel to achieve the purpose of headrest assembly. However, this method cannot quickly change the corresponding pressing strip mold according to the required headrest size and shape, thus reducing work efficiency and failing to meet the needs of use.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a headrest pressing device, including a fixing plate 1. A quick-release mechanism 2 is provided on the top of the fixing plate 1. The quick-release mechanism 2 is used to install pressing structures of different sizes and types. A cutting mechanism 3 is installed on the outer side of the quick-release mechanism 2, used to cut excess fabric. The quick-release mechanism 2 includes a fixing frame 201, which is located at the top of the fixing plate 1. Grooves 202 are provided on both the left and right sides of the inner wall of the fixing frame 201. A spring 204 is fixedly connected to the inner side of the groove 202, and a retaining cone 203 is fixedly connected to the end of the spring 204. A fixing block 206 is provided at the bottom of the fixing block 201. The left and right sides of the outer wall of the fixing block 206 are provided with slots 205, which engage with the fixing block 206. A reinforcing rib 208 is fixedly connected to the bottom of the fixing block 206, and a pressure frame 207 is fixedly connected to the outer wall of the reinforcing rib 208. A hydraulic cylinder 8 is fixedly connected to the top of the fixing plate 1, and the lower end of the hydraulic cylinder 8 is fixedly connected to the top of the fixing frame 201. A sliding groove 11 is provided on the left and right sides of the middle of the inner wall of the fixing frame 201. A slider 10 is fixedly connected on the left and right sides of the middle of the outer wall of the fixing block 206, and the slider 10 is slidably connected to the sliding groove 11.

[0032] Specifically, when performing the pressing operation on the headrest, the hydraulic cylinder 8 is activated to drive the pressing frame 207 downward to complete the pressing process. When it is necessary to replace the pressing strip, the fixing block 206 is placed or removed so that the slider 10 is aligned with the slide groove 11 and moves upward to limit the movement trajectory of the fixing block 206. During the upward movement of the fixing block 206, it touches the retaining cone 203, causing the spring 204 to pull the retaining cone 203 inward. When the retaining groove 205 moves to a position flush with the retaining cone 203, the retaining cone 203 is inserted into the retaining groove 205 to achieve locking and positioning, thereby limiting the position of the fixing block 206 and simultaneously fixing the pressing frames 207 and reinforcing ribs 208 of different specifications below. The replacement process can be completed by pulling down and pushing up, effectively improving work efficiency.

[0033] Reference Figure 1 , Figure 2 and Figure 5The cutting mechanism 3 includes a connecting rod 302, which is fixedly connected to the outer wall of the pressure frame 207. A cutting plate 301 is fixedly connected to the outer side of the connecting rod 302. A bearing block 304 is installed at the top center of the fixed plate 1. A cutting groove 303 is opened on the top wall of the bearing block 304. A placement groove 9 is opened on the inner side of the bearing block 304. The inner wall of the bearing block 304 is rounded. The cutting groove 303 and the cutting plate 301 are symmetrically designed.

[0034] Specifically, the headrest material is filled into the placement groove 9 of the bearing block 304. When the pressure frame 207 descends, it drives the connecting rod 302 and the cutting plate 301 to descend synchronously. During the pressing process, the cutting plate 301 is inserted into the cutting groove 303 to cut off the excess fabric around it. The symmetrical design of the cutting plate 301 and the cutting groove 303 can effectively improve the cutting accuracy.

[0035] Reference Figure 1 A support rod 4 is fixedly connected to the bottom of the fixed plate 1, and a base plate 5 is fixedly connected to the bottom of the support rod 4; a placement plate 6 is fixedly connected to the outside of the support rod 4, and a partition plate 7 is fixedly connected to the top of the placement plate 6.

[0036] Specifically, the stability of the equipment during operation is increased by the cooperation of the support rod 4 and the base plate 5, and items are placed by the cooperation of the placement plate 6 and the partition plate 7.

[0037] Working principle: When pressing the headrest, the hydraulic cylinder 8 is activated to drive the pressing frame 207 to descend, completing the pressing process. When it is necessary to replace the pressing strip, the fixing block 206 is taken and its slider 10 is aligned with the slide groove 11 and moved upward, limiting the movement trajectory of the fixing block 206. When the fixing block 206 rises, it collides with the locking cone 203, causing the spring 204 to pull the locking cone 203 inward. At the same time, the locking groove 205 moves to the level of the locking cone 203, so that the locking cone 203 is inserted into the locking groove 205 to lock, thereby fixing the position of the fixing block 206. This also fixes the pressing frame 207 and the reinforcing rib 208 of different shapes and sizes below. The replacement process can be completed by pulling down and pushing up.

[0038] The headrest material is filled into the placement groove 9 of the bearing block 304. When the pressure frame 207 descends, the connecting rod 302 and the cutting plate 301 descend synchronously. During the pressing process, the cutting plate 301 is inserted into the cutting groove 303 to cut off the excess fabric around it.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
