Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts, and more specifically, to a vehicle headrest bracket. Background Technology

[0002] Car headrest holders, a common automotive accessory, are typically mounted on the metal rods of car headrests, providing great convenience for drivers and passengers. For example, by securing a mobile phone or tablet, users can easily navigate, answer hands-free calls, or enjoy audio-visual entertainment for rear passengers. They can also be used to hang clothing, handbags, or other personal items to keep the car interior tidy and organized. These functions significantly improve the utilization of interior space and enhance the convenience and comfort of passengers.

[0003] To accommodate the different headrest support rod spacing of various car models, some adjustable car headrest brackets have emerged in the prior art. For example, Chinese Patent No. CN214396602U discloses a car headrest bracket, which includes a slide rail, end caps, claws, a lead screw, an elastic element, and a support base. The slide rail has a hollow cylindrical structure, and two end caps are fixed to both ends of the slide rail. Two claws are spaced apart and slidably connected to the slide rail. The lead screw is housed inside the slide rail and passes through a through hole on the claw before being rotatably connected to the end cap. The elastic element is elastically disposed inside the slide rail and elastically compressed between the two claws. During installation, the user needs to overcome the elastic force of the elastic element, pull the two claws apart to the sides, then put the bracket on the support rod of the car headrest, and finally release the claws, relying on the restoring force of the elastic element to lock the claws onto the support rod.

[0004] However, the aforementioned existing technology has drawbacks. For example, the bracket mainly relies on the elastic force of the elastic element to achieve clamping, and this clamping force is unstable. Under the bumps and vibrations during vehicle operation, the elastic element may deform or loosen, causing a decrease in the clamping force between the claw and the headrest support rod, or even causing the entire bracket to loosen or slip off, posing a safety hazard. At the same time, the elastic force of the elastic element will decrease with the increase of use time, further affecting the long-term reliability of the fixation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a vehicle headrest bracket in view of the above-mentioned defects of the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A vehicle headrest bracket includes a bracket body with a blower assembly and two engaging members that can be engaged with a car headrest support rod. The two engaging members are disposed opposite each other on the same side of the bracket body and can move linearly along the same straight line on the bracket body. The bracket body also has an adjustment assembly. The adjustment assembly includes two adjusting screws, which are rotatably disposed at both ends of the bracket body and threadedly connected to the two engaging members. During rotation, the adjusting screws can drive the corresponding engaging members to move linearly relative to the bracket body to adjust the distance between the two engaging members.

[0007] The vehicle headrest bracket of this utility model includes a bracket body comprising a first half-shell and a second half-shell that are interlocked, forming a receiving cavity between them; the receiving cavity includes two adjustment cavities and an electrical component receiving cavity located between the two adjustment cavities; an adjustment screw and a locking member are provided in the adjustment cavity, and the blower assembly is disposed in the electrical component receiving cavity.

[0008] The vehicle headrest bracket of this utility model includes two guide grooves between the first half-shell and the second half-shell. The two guide grooves are symmetrically arranged on both sides of the blower assembly and are slidably connected to the two locking members to guide the locking members to move in a straight line.

[0009] The vehicle headrest bracket of this utility model has an outwardly protruding heat dissipation part in the middle of the bracket body, which is used to be inserted between the two support rods of the car headrest; the electrical component receiving cavity serves as the inner cavity of the heat dissipation part; the heat dissipation part has an air outlet on the side facing the driver, and the air blowing assembly blows air towards the air outlet; a guide plate for adjusting the air blowing direction is also rotatably provided at the air outlet.

[0010] The vehicle headrest bracket of this utility model includes a main control board and a lithium battery inside the electrical component housing cavity. The blower assembly and the lithium battery are both electrically connected to and controlled by the main control board.

[0011] The vehicle headrest bracket of this utility model includes a connecting part that is threadedly connected to the adjusting screw, a guiding part that slides with the guide groove, and a hook part that protrudes from the bracket body.

[0012] The vehicle headrest bracket of this utility model has symmetrical slots for engaging the car headrest support rod on one side of each of the two hook parts that are opposite or back to each other.

[0013] The vehicle headrest bracket of this utility model is further provided with a control switch for controlling the working state of the blower assembly and a charging plug for charging the lithium battery, both of which are electrically connected to the main control board.

[0014] The vehicle headrest bracket of this utility model includes an adjusting screw comprising a screw body and a rotating cap fixedly connected thereto; the bracket body is provided with a rotating surface for the rotating cap to rotate, and the screw body is rotatably mounted on the rotating surface via a rotating bearing seat; during the rotation of the adjusting screw, the rotating bearing seat can limit the axial displacement of the screw body.

[0015] The vehicle headrest bracket of this utility model has at least one hook rotatably provided on the side of the bracket body facing away from the locking member.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This solution features two independently or synchronously adjustable locking components, each driven by a separate adjusting screw. Users can precisely and independently control the position of each locking component by rotating the adjusting screws at both ends, achieving a wide range of stepless spacing adjustment between the two components. This design allows the bracket to easily adapt to the headrest supports of most car models on the market, fundamentally solving the core pain point of poor versatility in existing brackets.

[0017] 2. This solution employs a threaded connection between the adjusting screw and the locking component. Threaded transmission offers significant mechanical force amplification and excellent self-locking properties. Once the user rotates the screw to clamp the locking component onto the headrest support, it will not loosen under any bumps or vibrations during vehicle operation unless actively rotated in the opposite direction. This mechanical, rigid locking completely solves the problems of unstable clamping force, easy attenuation, and easy loosening caused by relying on elastic force, ensuring the stability and safety of the bracket during travel.

[0018] 3. Compared to existing designs that require force to open the elastic jaws, users can simply rotate the screw to move the locking mechanism. The operating torque is low, and it can be easily completed with one hand. Simultaneously, the screw drive precisely converts rotational motion into linear motion, allowing users to intuitively control the moving distance of the locking mechanism and the final clamping force, enabling precise adjustment and significantly improving the user experience.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] A preferred embodiment of this utility model provides a vehicle headrest bracket, such as... Figure 1-4 As shown, the vehicle headrest bracket mainly includes a bracket body 10, a blower assembly 20 mounted on the bracket body 10, two locking parts 30, and an adjustment assembly 40.

[0030] The support body 10 serves as the base of the entire device. In this embodiment, the support body 10 is formed by the first half-shell 11 and the second half-shell 12 fastened together by screws or clips, creating a hollow receiving cavity. This receiving cavity is divided into three parts by two internal partitions 13: two adjustment cavities 131 and one electrical component receiving cavity 132; the two adjustment cavities 131 are symmetrically distributed on both sides of the electrical component receiving cavity 132. By dividing the receiving cavity into multiple cavity structures with different functions, physical isolation and optimized layout of each functional module are achieved. The adjustment cavity 131 provides an independent and protected space for the movement of the locking component 30 and the installation of the distance adjustment assembly 40, preventing interference between their movement and the electrical components; while the electrical component receiving cavity 132 provides a centralized and safe installation environment for precision electronic components such as the main control board 21, lithium battery 22, and blower assembly 20, facilitating heat dissipation design and electromagnetic shielding, thereby improving the stability and reliability of the entire product.

[0031] In one embodiment, the air blowing assembly 20 is used to blow air onto the driver's back, effectively improving the stuffiness during summer or long-distance driving, providing active heat dissipation, and significantly improving driving comfort. Specifically, the middle part of the bracket body 10 is designed as an outwardly protruding rectangular heat dissipation section 101. The width of the heat dissipation section 101 is adapted to the width between the two support rods of the car seat headrest, and its end face does not protrude from the surface of the seat back, so that the bracket will not press against the driver's back after installation. The electrical component receiving cavity 132 serves as the inner cavity of the heat dissipation section 101.

[0032] Furthermore, the blower assembly 20 is disposed within the electrical component housing cavity 132. In this embodiment, the blower assembly 20 is a small centrifugal fan or axial fan, or a single-wheel or dual-wheel turbofan. The electrical component housing cavity 132 also houses a lithium battery 22 that powers the entire device and a main control board 21 that controls the operation of each electrical component. Both the blower assembly 20 and the lithium battery 22 are electrically connected to the main control board 21 via wires.

[0033] The heat dissipation unit 101 has an air vent 1011 on the side facing the driver. When the air blowing assembly 20 is working, the airflow is blown out from the air vent 1011 and directly acts on the driver's back. At the air vent 1011, an air guide plate 17 is also rotatably mounted via a pivot. The user can manually move the air guide plate 17 up and down to adjust its angle, thereby changing the air blowing direction and achieving precise air delivery.

[0034] In another embodiment, the air blower assembly 20 is used to blow air towards the rear passengers, improving their comfort. The air blower assembly 20 is located on the side of the bracket body 10 facing the rear passengers.

[0035] In this embodiment, a control switch 15 and a charging plug 16 (such as a USB interface or Type-C interface in the prior art) are also provided on the outer surface of the bracket body 10. The control switch 15 can be a push-button switch, used to control the opening and closing of the blower assembly 20. The charging plug 16 is electrically connected to the main control board 21 and is used to charge the lithium battery 22.

[0036] In this embodiment, the adjusting assembly 40 is the core structure for achieving the versatility and reliability of this utility model. The adjusting assembly 40 includes two adjusting screws 41. Each adjusting cavity 131 is provided with an adjusting screw 41 and a corresponding engaging member 30.

[0037] The adjusting screw 41 includes a screw body 411 and a rotating cap 412 fixed to one end of the screw body 411. The rotating cap 412 can be a disc-shaped or butterfly-shaped structure with anti-slip texture, which is convenient for the user to rotate manually. On the outer surface of the bracket body 10, a rotating surface 111 is provided corresponding to the position of the rotating cap 412, and the rotating cap 412 can rotate on the rotating surface 111.

[0038] To ensure smooth rotation of the adjusting screw 41 without axial movement, the end of the screw body 411 near the rotating cap 412 is rotatably mounted on the rotating surface 111 via a rotating bearing seat 413. The inner ring of the rotating bearing seat 413 is fixed to the screw body 411, the outer ring is secured to the hole wall of the rotating surface 111, and its end face abuts against the inner side of the support body, thereby effectively restricting the outward movement of the screw body 411. The free end of the screw body 411 passes through the partition 13 and is rotatably connected via a simple bearing or directly to a hole in the partition 13.

[0039] Please see Figure 5 The engaging component 30 includes a connecting part 31, a guide part 32, and a hook part 33. The connecting part 31 has a threaded hole that matches the adjusting screw 41. The guide part 32 is slider-shaped, and its two sides have grooves that slide along the edges of the guide groove 14. The hook part 33 is an L-shaped or J-shaped hook used to engage the support rod of the car headrest.

[0040] Furthermore, the guide groove 14 is formed by the engagement of a first groove on the first half-shell 11 and a second groove on the second half-shell 12. The two guide grooves 14 are symmetrically arranged on both sides of the blower assembly 20. The guide portion 32 of the engaging member 30 is embedded in the guide groove 14 and can slide within it. The function of the guide groove 14 is to guide the engaging member 30 to make precise linear movements and to prevent it from rotating under the influence of the adjusting screw 41.

[0041] Furthermore, a slot 331 is provided on the hook portion 33. In this embodiment, the slot 331 is provided on the opposite side surface of the two hook portions 33 for clamping the headrest support rod. In another embodiment, the slot 331 may also be provided on the opposite side surface of the two hook portions 33 to form an external locking structure to accommodate support rods of different shapes.

[0042] In addition, one or two hooks 18 are rotatably mounted on the side of the bracket body 10 facing away from the latching member 30, i.e., the side facing the back of the car seat. These hooks 18 can be folded for storage and unfolded when needed to hang small items such as shopping bags, headphones, and umbrellas, increasing the practicality of the bracket.

[0043] The installation and usage process of this embodiment is as follows: Mounting the bracket: Align the heat dissipation part 101 of the bracket body 10 with the gap between the two headrest support rods, align the hook parts 33 of the two engaging parts 30 with the two support rods respectively, and insert the bracket. Then, rotate the rotating caps 412 at both ends in the opposite direction to move the two engaging parts 30 towards each other until the locking grooves 331 on them are firmly clamped onto the headrest support rods. The screw's self-locking characteristic ensures the stability of the installation, completely solving the problem of easy loosening caused by relying on elastic elements for fixing in the prior art. It is worth noting that the principle of screw self-locking is a common principle in the mechanical field, and will not be elaborated here.

[0044] Using the blower function: Press the control switch 15 to activate the blower assembly 20. The main control board 21 controls the lithium battery 22 to power the blower assembly 20, and airflow is blown out from the air outlet 1011 to cool the driver's back. The user can adjust the airflow direction by moving the air guide plate 17 as needed. When the lithium battery 22 is low on power, it can be charged by connecting to a car charger or power bank via the charging plug 16.

[0045] In summary, the vehicle headrest bracket provided by this utility model, through its ingenious structural design, achieves wide compatibility and reliable fixation for different vehicle models, and innovatively integrates an active airflow cooling function, greatly enhancing the product's practicality and user experience.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
