Description

Technical Field

[0001] The invention relates to a vehicle footrest, in particular to a backrest foot support device. Background Art

[0002] With the advancement of automotive technology and the improvement of quality of life, consumers are demanding increasingly higher levels of comfort in their vehicles. Currently, to enhance the riding experience for passengers in the middle and rear seats, some mid- to high-end vehicles offer footrests to support the passengers' feet. These footrests typically consist of a footrest plate and a drive module. The footrest plate is mounted behind the front seatback and, driven by the drive module, flips downward for deployment.

[0003] The footrests currently available on the market only have a simple foot support function. In the extremely competitive automotive market environment, as a comfort device, the footrest has some personalized and humanized comfort configurations, which will play a decisive role in its competitiveness in the automotive market. Summary of the Invention

[0004] In view of this, the present invention provides a backrest foot support device to enhance the comfort and luxury of existing footrests.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows:

[0006] A backrest foot support device includes a backrest and a flip-up footrest connected to the back side of the backrest. The key point is that the back side of the backrest is provided with an air inlet and an air outlet, and an air circulation mechanism is installed inside the backrest. When the footrest is opened, the air circulation mechanism can form a circulating airflow in the area above the footrest through the air inlet and the air outlet.

[0007] With the above structure, when a passenger uses the footrest, the air in the space where the feet are located enters the backrest through the air inlet and is then discharged outward from the air outlet, forming an internal and external circulating airflow in the rear area of the backrest, allowing the passenger's feet to relax while obtaining a better user experience, preventing the odor of the feet from affecting the air quality in the car, thereby achieving the purpose of ventilation and deodorization, and effectively improving the comfort and sense of luxury of the footrest.

[0008] Preferably, the backrest has a recessed area, with the air inlet and outlet located in the recessed area. The footrest, when folded, covers the recessed area. With this structure, when the footrest is in use, the user's feet are close to the air inlet and outlet, ensuring effective air purification. When the footrest is folded, the air inlet and outlet are completely covered, maintaining the seat's aesthetic quality.

[0009] Preferably, the air inlet is arranged below the air outlet, wherein the air inlet is composed of a plurality of small holes, and the air outlet comprises an array of small exhaust openings distributed along the width of the backrest, with the opening direction of the small exhaust openings being arranged to be inclined downward. The above structure can further ensure ventilation.

[0010] Preferably, the air circulation mechanism includes an air duct connecting the air inlet and the air outlet, and a circulation fan arranged on the air duct. The above structure is adopted to form an internal and external circulating airflow in the backrest area.

[0011] Preferably, the backrest is provided with an air duct component, the outer side of which is formed with a groove. The backrest has a back panel at its rear, and the outer side of the air duct component is fixedly connected to the inner side of the back panel, so that the groove and the back panel together form the air duct. With this structure, the air duct structure layout is rationally designed and facilitates production, manufacturing, and assembly.

[0012] Preferably, the air duct component comprises two symmetrically arranged longitudinal segments, a transverse segment integrally connected between the upper ends of the two longitudinal segments, and a bent segment respectively disposed at the lower ends of the two longitudinal segments, wherein the circulating fan is mounted between the two bent segments, the air inlet being located at a position on the back panel corresponding to the bent segment, and the air outlet being located at a position on the back panel corresponding to the transverse segment. With this structure, the circulating fan can generate an internal and external circulating airflow in the rear area of the backrest, achieving effective air circulation.

[0013] As a preferred embodiment, an ultraviolet lamp is provided in the air circulation mechanism. The above structure can achieve the effect of deodorization.

[0014] As a preferred embodiment, a plasma disinfection component is provided in the air circulation mechanism. The above structure can achieve the effect of disinfection and sterilization.

[0015] Preferably, a bracket assembly is mounted inside the backrest, a swing arm assembly is fixed to the footrest, and the swing arm assembly is rotatably mounted on the bracket assembly. A drive mechanism is mounted inside the backrest, and the drive mechanism can drive the swing arm assembly to rotate out of or into the backrest via a telescopic motion to open or close the footrest. With this structure, the drive mechanism controls the footrest's flipping via a telescopic motion within a backrest with limited available space, ensuring that the entire internal drive module does not occupy excessive space within the backrest frame, thereby facilitating a thin design without increasing the backrest's thickness.

[0016] Preferably, a lug is provided on one side of the swing arm assembly, and the driving mechanism is an electric push rod, one end of which is hinged on the backrest and the other end is hinged on the lug. With the above structure, the electric push rod can drive the footrest to rotate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The backrest footrest is endowed with ventilation, deodorization and air purification functions, which significantly improves the comfort and luxury of the footrest, and is especially suitable for mid-to-high-end configuration cars.

[0019] 2. The ventilation structure is reasonably designed, easy to manufacture, and the product is easy to implement.

[0020] 3. The footrest is rotated and expanded by the telescopic movement of the electric push rod. The drive module inside the backrest does not take up too much space in the backrest frame, realizing a thin structural design without increasing the thickness of the backrest.

[0027] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0028] like Figure 4 and 5 As shown, a backrest foot support device includes a backrest A and a footrest B arranged on the rear side of the backrest A. A bracket assembly 10 is installed on the internal frame of the backrest A, and a swing arm assembly 7 is fixedly installed on the footrest B. The swing arm assembly 7 is rotatably connected to the bracket assembly 10. A support ear 7a is provided on one side of the swing arm assembly 7. A driving mechanism 8 is installed inside the backrest A. In this embodiment, the driving mechanism 8 is preferably an electric push rod. The upper end of the electric push rod is hinged in the backrest A, and the lower end is hinged on the support ear 7a. The upward and downward telescopic movement of the electric push rod can make the entire swing arm assembly 7 rotate relative to the bracket assembly 10, that is, the upward contraction of the electric push rod can make the footrest B flip backward to Figure 1The electric push rod extends downward to rotate the footrest B forward to Figure 6 The state shown is to achieve the folding of the foot support plate B.

[0029] The electric push rod is arranged along the height direction of the backrest A. This design can make full use of the internal space of the backrest frame and occupy less backrest space, so that the entire internal drive module will not occupy too much backrest frame space, which is conducive to achieving a thin design without increasing the backrest thickness.

[0030] like Figure 1 and 2 As shown, an air inlet 1 and an air outlet 2 are provided on the rear side of the backrest A, and an air circulation mechanism 3 is installed inside the backrest A. After the user's feet are supported on the footrest B, under the action of the air circulation mechanism 3, the air in the space where the feet are located enters the backrest A through the air inlet 1, and is then discharged outward from the air outlet 2. In this way, an internal and external circulating airflow can be formed in the rear area of the backrest A, which helps to increase the air circulation, thereby achieving the purpose of ventilation and deodorization, and can effectively enhance the comfort and luxury of the footrest.

[0031] In this embodiment, the backrest A has a backboard 5 on the backboard 5, which has a recessed area a. The air inlet 1 and the air outlet 2 are both located in the recessed area a. When the foot support device is folded, the footrest B covers the recessed area a. This structural layout has three technical advantages. First, when the footrest B is in use, the user's feet are closer to the air inlet and outlet, which can ensure the effectiveness of air purification. Second, after the footrest B is folded (see Figure 6 ), the air inlet and outlet are completely covered by the footrest B, and the seat has a better appearance quality; thirdly: after the footrest B is folded, the thickness of the backrest A will not increase, and the rear passengers have better comfort during normal riding.

[0032] like Figure 2 and 3As shown, the air circulation mechanism 3 includes a duct component 6 and a circulation fan 4, wherein the duct component 6 includes two symmetrically arranged longitudinal sections 6b, a transverse section 6c is integrally formed between the upper ends of the two longitudinal sections 6b, and the lower ends of the two longitudinal sections 6b are respectively provided with a bending section 6d bent inwardly, the longitudinal section 6b, the transverse section 6c and the bending section 6d constitute the duct component 6, and the outer sides of the two longitudinal sections 6b, the transverse section 6c and the two bending sections 6d are formed with a through-hole groove 6a. After the outer side of the duct component 6 is fixedly connected to the inner side of the back panel 5, the above-mentioned duct d is formed between the groove 6a and the back panel 5, and the circulation fan 4 is installed at the gap between the two bending sections 6d, the air inlet 1 is arranged at the position of the back panel 5 corresponding to the bending section 6d, and the air outlet 2 is arranged at the position of the back panel 5 corresponding to the transverse section 6c. When the circulation fan 4 is working, the air can enter the duct d from the air inlet 1, and then be discharged outward from the air outlet 2, thereby forming an internal and external circulating airflow in the rear area of the backrest A.

[0033] In addition to being arranged between the groove 6a of the air duct component 6 and the back plate 5, the air duct d can also be replaced by a separate ventilation pipe.

[0034] For example Figure 1 As shown, in order to further improve the ventilation effect, the air inlet 1 is composed of a number of small holes b, and the air outlet 2 includes an array of exhaust ports c distributed along the width direction of the backrest A. The opening direction of the exhaust ports c is tilted downward, which can make the air flow blow directly downward, helping to form negative pressure at the position of the air inlet 1, making it easier for air to be sucked into the air duct d.

[0035] In order to achieve the effect of deodorization, an ultraviolet lamp is provided in the air circulation mechanism 3. In order to achieve the effect of disinfection and sterilization, a plasma disinfection component 9 is provided in the air circulation mechanism 3. In this embodiment, the ultraviolet lamp and the plasma disinfection component 9 can be directly installed in the air duct d.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
