Description

Technical Field

[0001] This utility model relates to the field of headrest technology, and in particular to a multifunctional car seat headrest. Background Technology

[0002] Car seat headrests are an important component of car seats, primarily used to provide support and protection for the heads of drivers and passengers, especially in the event of a collision, where they act as a buffer to absorb energy and reduce the risk of neck injuries. Simultaneously, during daily driving or riding, headrests also enhance comfort and alleviate fatigue. Therefore, car seat headrests not only affect the comfort of the vehicle ride but also directly impact passenger safety. Multifunctional car seat headrests occupy an important position in the field of automotive interiors and safety equipment. As a key component for head support and safety protection for drivers and passengers, their structural design, material selection, and functional integration have a decisive impact on overall ride comfort and safety. Particularly in the core aspects of headrest support adjustment, collision buffering, and ventilation, existing headrest structures / designs / technologies are gradually revealing a series of significant limitations and technical problems when dealing with users of different body types, complex working conditions, and diverse usage needs.

[0003] Specifically, the existing utility model patent CN220535492U discloses a car seat headrest structure, including a front panel and a back panel, which are respectively combined with a first foam layer and a second foam layer. By setting foam materials with different hardness, the feel and support performance of the headrest are optimized, thereby replacing the traditional injection molded part structure and achieving the purpose of reducing costs and weight.

[0004] However, in practical applications, this structure still has many shortcomings. Existing headrests have limited energy absorption and cushioning effects, making it difficult to provide sufficient head protection in sudden collisions. Furthermore, the dense internal structure of the headrest results in poor breathability, easily causing stuffiness and discomfort during prolonged use, affecting seating comfort. More seriously, these problems not only significantly reduce user satisfaction and product competitiveness but may also pose potential risks to the personal safety of drivers and passengers due to insufficient protective performance. Therefore, to address the many shortcomings of existing technologies, we urgently need an innovative, multi-functional automotive seat headrest to solve these problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a multifunctional car seat headrest, including a frame, a soft plate slidably connected to the inner side of the frame, and a top plate fixedly connected to the top of the frame;

[0007] An arc-shaped soft pad is fixedly connected between the top plate and the soft plate. A box body is fixedly connected to one side of the frame. Several piston tubes are provided on the inner side of the frame. One end of each piston tube passes through the side wall of the frame and is connected to one side of the box body.

[0011] All piston tubes have a fixed sleeve fitted on one end, and several fixed plates are fixedly connected to one side of the flexible plate. The fixed plates are elastically connected to one side of the fixed sleeve through a compression spring.

[0012] The inner side of the housing is filled with coolant, and a valve body is connected to one side of the bottom of the housing.

[0013] This utility model discloses a multifunctional car seat headrest. Through a hydraulic buffer system composed of a frame, soft plate, piston rod, piston, piston tube, and housing, it generates resistance through liquid flow upon external impact, achieving efficient energy absorption and buffering.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figure 1-6 ,

[0024] A multifunctional car seat headrest includes a frame 1, a soft plate 4 slidably connected to the inner side of the frame 1, and a top plate 2 fixedly connected to the top of the frame 1.

[0025] An arc-shaped soft pad 3 is fixedly connected between the top plate 2 and the soft plate 4. A box 8 is fixedly connected to one side of the frame 1. Several piston tubes 14 are provided on the inner side of the frame 1. One end of all piston tubes 14 passes through the side wall of the frame 1 and communicates with one side of the box 8. A piston 20 is provided on the inner side of all piston tubes 14. A piston rod 15 is fixedly connected to one side of all pistons 20. One end of all piston rods 15 is fixedly connected to one side of the soft plate 4. A fixing strap 9 is fixedly connected to one side of the outer wall of the frame 1. An adhesive plate 10 is sleeved on one end of the fixing strap 9. A connecting plate 11 is provided on one side of the adhesive plate 10.

[0026] First, attach the connecting plate 11 to the appropriate position on the back of the car seat. Then, wrap the fixing strap 9 around the headrest installation area and attach the adhesive plate 10 to the connecting plate 11 to firmly fix the entire headrest to the seat. When the user leans their head against the headrest, the soft plate 4 is pressed and slides into the frame 1, driving the piston rod 15 to push the piston 20 to move in the piston tube 14, squeezing the liquid in the box 8 to form a dynamic hydraulic buffer effect, effectively absorbing and dispersing the impact force from the head. At the same time, the arc-shaped soft pad 3 and the soft plate 4 work together to provide the user with a soft and supportive experience, avoiding the oppressive feeling brought by traditional hard headrests. This structure can improve the riding comfort in daily use and significantly enhance the protection of the head in the event of a sudden collision.

[0027] Furthermore, sliders 5 are fixedly connected to both sides of the soft plate 4, and both sliders 5 are slidably connected to the inner wall of the frame 1 through grooves 6. When pressure is applied to the soft plate 4 by the head, the sliders 5 slide along the direction of the grooves 6, which plays a guiding and limiting role, ensuring that the soft plate 4 remains stable and does not deviate during the pressure-induced movement. This structure improves the smoothness and running accuracy of the soft plate 4 during the sliding process. It achieves the effect of enhancing the guiding and stability of the movement of the soft plate 4, and improving the reliability and comfort of the overall cushioning response of the headrest.

[0028] Furthermore, a heat dissipation plate 12 is fixedly connected to one side of the inner side of the frame 1, and several heat-conducting rods 7 are fixedly connected to the top of the heat dissipation plate 12. One end of all the heat-conducting rods 7 penetrates through the top plate 2, and the extensions of all the heat-conducting rods 7 penetrate through the top of the housing 8. During prolonged use, the heat generated by the human head is conducted through the top plate 2 and the arc-shaped soft pad 3 to the heat-conducting rods 7, and then transferred by the heat-conducting rods 7 to the liquid filling the housing 8. It is then diffused outward through the heat dissipation plate 12, achieving an active heat dissipation function. This structure effectively improves the stuffiness problem caused by the dense material of traditional headrests. It achieves the effect of improving the overall heat dissipation performance of the headrest, significantly improving riding comfort, and extending the continuous use time.

[0029] Furthermore, a sloping plate 13 is fixedly connected to one side of the top of the soft board 4, and one side of the sloping plate 13 is fixedly connected to one side of the curved soft pad 3. The sloping plate 13 serves as a transitional support structure, enhancing the connection strength between the soft board 4 and the curved soft pad 3. Simultaneously, it guides the force distribution more evenly under pressure, avoiding deformation or damage caused by localized stress concentration. This achieves the effect of enhancing the overall rigidity and stress uniformity of the headrest structure, improving its service life and stability during use.

[0030] Furthermore, a fixing sleeve 16 is fitted onto one end of each piston tube 14, and several fixing plates 18 are fixedly connected to one side of the soft plate 4. One side of each fixing plate 18 is elastically connected to one side of the fixing sleeve 16 via a compression spring 17. When the soft plate 4 is impacted, causing the piston rod 15 to compress the hydraulic system, the compression spring 17 provides a counter-force, giving the entire cushioning system a certain degree of self-recovery capability, thereby improving the headrest's rebound response speed and cushioning sensitivity. This achieves the effect of enhancing the dynamic response and resilience of the headrest cushioning system, and improving its continuous protection performance under multiple impacts.

[0031] Furthermore, the inner side of the housing 8 is filled with coolant, and a valve body 19 is connected to one side of the bottom of the housing 8. The coolant inside the housing 8 not only serves as a hydraulic buffer but also absorbs and conducts heat, helping to absorb heat from the heat-conducting rod 7 and achieve internal circulation and heat dissipation. When the coolant needs to be replaced or maintained, it can be drained or replenished through the valve body 19, improving the maintainability of the equipment. This achieves a multi-functional integrated design for the headrest, combining buffering and heat dissipation performance while facilitating later maintenance and upkeep.

[0032] In summary:

[0033] First, attach the connecting plate 11 to the appropriate position on the back of the car seat. Then, wrap the fixing strap 9 around the headrest installation area to bond the adhesive plate 10 to the connecting plate 11, thus completing the overall fixation of the headrest. When the user leans their head against the headrest, the pressure of the head is applied to the curved soft pad 3, which in turn pushes the soft plate 4 to slide into the frame 1. Due to the cooperative design of the slider 5 and the slide groove 6, the soft plate 4 remains stable and does not shift during the movement. The sliding of the soft plate 4 drives the piston rod 15 to push the piston 20 to move in the piston tube 14, compressing the coolant in the housing 8 and forming a dynamic hydraulic buffer effect, effectively absorbing impact energy and improving collision protection performance. At the same time, the compression between the fixing plate 18 and the fixing sleeve 16... Spring 17 provides rebound force, giving the headrest good self-recovery ability. It can quickly return to its original position after pressure is released, enhancing user comfort. During long-term daily use, the heat generated by the human head is conducted through the top plate 2 and the arc-shaped soft pad 3 to the heat-conducting rod 7, and further transferred to the coolant in the housing 8. Then, it is dissipated to the external environment through the heat dissipation plate 12, realizing active heat dissipation and avoiding stuffiness and discomfort. When the coolant needs to be replaced or maintained, it can be drained or replenished through the valve body 19, improving the maintainability of the equipment. The inclined plate 13 strengthens the connection between the soft plate 4 and the arc-shaped soft pad 3, ensuring uniform stress distribution and preventing deformation or damage caused by local stress concentration. The hydraulic buffer system, composed of frame 1, soft plate 4, piston rod 15, piston 20, piston tube 14, and housing 8, generates resistance through fluid flow when subjected to external impact, achieving efficient energy absorption and buffering. This solves the problem of insufficient buffering performance of traditional foam headrests during collisions, significantly improving the safety protection level. The design of slider 5 and groove 6 improves the guidance and operational stability of soft plate 4 during sliding, making the buffering response more reliable. The arc-shaped soft pad 3 works synergistically with soft plate 4, not only enhancing the fit and softness of the headrest surface but also, combined with the sliding adjustment function of soft plate 4, providing personalized support for users of different body types, thus improving safety. Adaptability and comfort in use; the heat dissipation structure composed of heat-conducting rod 7, heat dissipation plate 12 and housing 8 effectively improves the stuffiness problem caused by the dense material of traditional headrests, significantly improving riding comfort; the inclined plate 13 enhances the overall rigidity of the structure, improving the stability and durability of the headrest under long-term use; the compression spring 17 between the fixing plate 18 and the fixing sleeve 16 enhances the dynamic response and resilience of the cushioning system, enabling it to maintain good protective performance under multiple impacts; the housing 8 is filled with coolant and equipped with valve body 19, which not only realizes the hydraulic cushioning function, but also has the functions of heat absorption and heat conduction, and facilitates later maintenance, improving the practicality and reliability of the product.In summary, this multi-functional car seat headrest not only effectively solves the problems of poor cushioning performance, single structural function, and inconvenient installation in existing technologies, but also demonstrates significant advantages in improving safety, comfort, lightweight design, and ease of installation. It can better meet the actual needs of modern car seat systems for high-performance, multi-functional headrests and has good market application prospects and promotional value.
