TECHNICAL FIELD
[0001] The utility model belongs to the technical field of automobile seat accessories, and particularly relates to an adjustable auxiliary pillow of an automobile seat headrest for assisting in stepless adjustment of the headrest of an automobile seat to the height of user head support and improving driving comfort and adaptability. BACKGROUND
[0002] Early automobile seat headrest designs mainly have fixed heights, and their core functions only focus on safety protection (such as preventing neck injury when rear-ending), and comfort adaptation is ignored. For example, most economy cars (such as Volkswagen Jetta and Toyota Corolla classic models) from the 1990s to the early 2000s all adopt integrated headrest structures and cannot be adjusted in height. Such designs expose significant defects in actual use:
[0003] (1) Poor user adaptability: drivers and passengers of different heights and body types have very different demands for headrest support height. Users with higher heights often complain that the headrest support point is lower than the back of the head, causing the neck to be suspended; and users with shorter bodies face the discomfort of the headrest pressing the back of the head.
[0004] (2) Increased fatigue during long-distance driving: fixed support positions cannot be adjusted slightly according to the sitting posture, and long-time driving easily causes shoulder and neck muscle stiffness, reducing comfort.
[0005] Such problems are repeatedly mentioned in user surveys, but due to the technical conditions at the time, manufacturers often choose to sacrifice comfort to control costs.
[0006] To improve the defects of fixed headrests, height adjustment functions have been introduced into automobile headrests in recent years. For example, the "six-position manual headrest of an automobile seat" disclosed in Chinese Patent Application No. 2014206701903 realizes step adjustment by setting four gear slots on the lower segment support rod of the headrest rod. However, such technology still has the following shortcomings:
[0007] (1) Low adjustment accuracy: the gear slot spacing is usually 2-3 cm, only supporting four gear adjustments, which cannot meet the millimeter-level fine adjustment requirements. For example, users with heights of 175 cm and 178 cm may need the same gear, causing the support position to deviate.
[0008] (2) Inconvenient operation: when adjusting, the unlocking button needs to be pressed and the headrest needs to be manually lifted, which is tedious and prone to accidental gear shifting in bumpy road conditions.
[0009] (3) Mechanical wear and tear: frequent gear shifting easily causes wear and tear of the contact surface between the gear slot and the plug-in rod, and long-term use may cause problems such as looseness and abnormal noise.
[0010] Although such step adjustment solutions are an improvement over fixed headrests, they are still essentially "limited selection" rather than "free adaptation" and cannot completely solve the comfort problem.
[0011] To pursue higher adjustment freedom, some high-end vehicles attempt to introduce complex mechanical or electric adjustment technology. For example, multi-directional adjustment of the headrest is achieved by built-in motor-driven gears or sliding rails, which supports stepless adjustment but also has significant defects:
[0012] (1) High cost: The addition of motors, control modules, and sensors increases the cost of the headrest by several times, which is limited to luxury car models.
[0013] (2) Reliability risk: Electronic components are susceptible to moisture and vibration, resulting in high failure rates and heavy user burden for maintenance, which requires disassembly of the seat assembly.
[0014] In addition, the above solutions integrate the adjustment function inside the headrest body, resulting in the need to modify the original headrest structure (such as installing a sliding rail base), making it difficult for users to modify themselves, and old models cannot be compatible. In addition, ordinary users have limited demand for multi-directional adjustment, and complex design increases the use threshold and functional redundancy.
[0015] In view of the adjustment limitations of the original headrest, some external auxiliary products (such as memory foam headrest covers and U-shaped pillows) have appeared on the market, but their design has obvious shortcomings:
[0016] (1) Fixed additional structure: Only fillers are used to improve comfort, and the support height cannot be adjusted, which is a temporary solution.
[0017] (2) Temporary fixation method: Relies on elastic bands or hooks for fixation, which can be easily displaced during driving and poses a safety hazard.
[0018] (3) Lack of modular design: The one-piece structure does not support pillow replacement and cannot adapt to different scenarios (such as breathable pillows in summer and thick pillows in winter).
[0019] Such products partially alleviate the comfort problem, but cannot fundamentally solve the height adaptation and stable adjustment problem. Therefore, there is an urgent need for a simple structure, stepless adjustment, and strong adaptability of the headrest auxiliary device to solve the above problems.
[0020] In order to continue to solve the above problems, the auxiliary pillow of the existing automobile seat headrest needs to be further optimized and improved in structure. SUMMARY
[0021] The purpose of the present application is to provide a simple structure, stepless adjustment, and strong adaptability of the automobile seat headrest adjustable auxiliary pillow, which can adapt to new and old models, achieve precise positioning of the height through a damping sliding structure, and support modular replacement of the auxiliary pillow body.
[0022] To achieve the above object, the technical scheme of the utility model lies in: an adjustable auxiliary pillow of an automobile seat headrest, comprising a base, a vertical guide structure, a damping sliding structure and an auxiliary pillow body;
[0023] The base is used for detachable installation on the automobile seat headrest, and the front side of the base is provided with the vertical guide structure;
[0024] The damping sliding structure is arranged on the vertical guide structure, can be locked at any position of the vertical guide structure through friction or elastic deformation, and can slide along the vertical guide structure under external force;
[0025] The auxiliary pillow body is arranged on the damping sliding structure, slides with the damping sliding structure and is locked at any height position, so that stepless adjustment of the height of the auxiliary pillow body is realized.
[0026] Preferably, the vertical guide structure is a vertical adjusting belt or a vertical adjusting plate.
[0027] When the vertical guide structure is a vertical adjusting belt, the damping sliding structure comprises an adjusting sheet, sliding adjusting perforations are formed in the two sides of the adjusting sheet, and the vertical adjusting belt is arranged in the sliding adjusting perforations; the middle part of the adjusting sheet is provided with an installation perforation, the back side of the auxiliary pillow body is connected with an installation cloth sheet, and the installation cloth sheet is fixed through magic tape or snap fastener after passing through the installation perforation.
[0028] When the vertical guide structure is a vertical adjusting plate, the damping sliding structure comprises an elastic contraction sleeve, the elastic contraction sleeve is sleeved on the vertical adjusting plate, the elastic contraction sleeve generates friction resistance with the vertical guide structure through elastic deformation of the elastic contraction sleeve to lock the height, and the auxiliary pillow body is connected to the outer surface of the elastic contraction sleeve.
[0029] Preferably, the back of the base is provided with a band and a plug buckle, and the base is detachably connected with the automobile seat headrest through the band and the plug buckle.
[0030] The utility model has the advantages as follows:
[0031] (1) the traditional headrest has a 2-3cm interval between the steps, the adjustment precision is insufficient, and it is difficult to meet the individual needs of users. The utility model allows users to adjust the height of the auxiliary pillow with millimeter level precision through the damping sliding structure. For example, a user with a height of 170cm can adjust the auxiliary pillow to the natural curvature support point of the cervical vertebra (about the middle and upper part of the headrest), and a user with a height of 185cm can accurately move the support point to the middle of the back of the head, avoiding the "gear mismatch" problem of the traditional step adjustment. The support comfort of the utility model is better than that of the original factory headrest, and the neck fatigue of long-distance driving can be reduced by more than 40%.
[0032] (2) The existing electric or hydraulic adjustment scheme relies on complex mechanical structure, resulting in high cost and high failure rate. The utility model discloses a pure mechanical damping sliding structure (such as adjusting piece perforation friction, elastic sleeve deformation), without electronic components or power drive, avoids the risk of motor failure, circuit aging, etc. The base is detachably connected with the headrest through a strap or buckle, and the damping sliding structure and the auxiliary pillow body are fixed by magic tape or snap fastener, supporting the modular assembly scheme of quick disassembly, especially suitable for medium and low-end vehicles and after-market, and users can install it by themselves without professional tools or modification service.
[0033] (3) The traditional adjustment scheme is limited by the original factory headrest structure (such as the size of the supporting rod, the fixed hole position), resulting in poor adaptability. The base of the utility model discloses a detachable fixing structure by strap insertion buckle, has strong compatibility, without any structural modification or additional support for the original factory headrest, avoiding the warranty invalidation or safety hazards caused by modification. According to statistics, there are more than 300 million old cars in China (manufactured before 2005), and the utility model can provide a low-cost comfort upgrade solution for this group.
[0034] (4) The traditional headrest has single function and cannot meet diversified needs. The utility model realizes function expansion through the replaceable design of the auxiliary pillow body and the quick disassembly structure of magic tape and snap fastener. For the form expansion of the auxiliary pillow body, optional modules such as U-shaped pillow (long-distance driving neck surrounding support), thickened pillow (off-road bumpy road cushion), breathable mesh pillow (summer ventilation) are provided; for the material upgrading of the auxiliary pillow body, users can individually purchase gel pillow body to replace the original memory foam pillow body, meeting the personalized needs. Special auxiliary pillow bodies can be configured for family members of different heights; the pillow body type can be replaced for different needs of online car passengers, improving the service score.
[0035] In summary, the utility model discloses a stepless adjustment mechanism, structure simplification, whole vehicle type adaptation and modular design, systematically solves the problems of low adjustment precision, poor comfort, high cost and single function of the traditional headrest, and has significant practical value and commercialization potential.
