Description

Technical Field

[0001] This utility model belongs to the field of steering wheel temperature control, and more specifically, it relates to a steering wheel with bidirectional temperature adjustment. Background Technology

[0002] Traditional car steering wheels are prone to becoming too hot to handle or too cold to handle in extreme summer and winter temperatures, affecting driving comfort and safety. Existing adjustment solutions mostly rely on heating or ventilation alone, failing to address both hot and cold needs, and some solutions suffer from low temperature control accuracy and slow response. As consumers demand a higher level of driving experience, there is a need for steering wheels that can adjust temperature in both directions, respond quickly, and maintain precise temperature control to address the pain points of traditional products and meet the demands for comfortable driving. This is the objective of this invention.

[0003] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a two-way temperature-adjustable steering wheel, which achieves cooling (heating) of the steering wheel by connecting the air outlet of the air conditioner inside the steering wheel, and adds heating wires to the steering wheel to achieve faster and more efficient heating, making driving more comfortable and improving the driving experience.

[0005] A two-way temperature-adjustable steering wheel includes a steering wheel assembly. The steering wheel assembly includes a pivot, a central axle compartment is fixedly connected above the pivot, and a first annular groove is fixedly connected to one end of the central axle compartment connected to the pivot. An air chamber is formed in the middle of the central axle compartment, and an air inlet and an air outlet are formed on the outer side of the central axle compartment outside the air chamber. The air inlet and air outlet are symmetrical about the pivot. Three connecting plates are fixedly connected to the upper outer side of the air chamber. An air inlet pipe and an air outlet pipe are fixedly connected to one of the connecting plates. A steering wheel is fixedly connected to the outer side of the three connecting plates. The steering wheel has a hollow structure and a baffle is sealed inside. An air inlet pipe and an air outlet pipe are sealed on both sides of the baffle on the steering wheel. The interior of the steering wheel is interconnected with the air inlet and the air outlet.

[0006] Preferably, a fixed air intake assembly is nested around the rotating shaft. The fixed air intake assembly includes an air intake column with a through-hole in the middle. The rotating shaft hole is rotatably connected to the rotating shaft. A first air chamber and a second air chamber are formed on the air intake column on both sides of the rotating shaft hole. A main air outlet pipe is sealed to the bottom of the first air chamber, and a main air intake pipe is sealed to the bottom of the second air chamber. A second annular groove is fixedly connected to the upper outer side of the air intake column, and a thread is provided on the lower outer side of the air intake column. The upper part of the air intake column abuts against the bottom of the central shaft compartment.

[0007] Preferably, a connecting bushing is fixedly connected to the outer side of the intake column. The connecting bushing has two semi-circular structures, and two threaded holes are opened on each side of the flat end of the connecting bushing. A rubber pad is fixedly connected to the flat end of the connecting bushing. A first convex ring and a second convex ring are fixedly connected to the middle of the inside of the connecting bushing. A screw is threaded into the threaded hole, and the two connecting bushings are fixed together by the screw. The first convex ring is slidably connected to the first ring groove, and the second convex ring is slidably connected to the second ring groove.

[0008] Preferably, the air inlet is located in the middle of the second air chamber, the air outlet is located in the middle of the first air chamber, and the thickness of the baffle between the first and second air chambers is greater than that of the air inlet and the air outlet.

[0009] Preferably, a heating wire is wound around the outside of the steering wheel, and a protective sleeve fixedly connected to the steering wheel is provided on the outside of the heating wire. The protective sleeve covers the connecting plate. A heating wire guard plate assembly is fixedly connected to one side of the central axle compartment. The heating wire guard plate assembly is connected to the positive and negative poles of the heating wire. A protective cover plate is also fixedly connected to the central axle compartment.

[0010] Preferably, an end cap is fixedly connected to the outer side of the airbag.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention connects the main intake pipe and main exhaust pipe to the air inlet and outlet of the vehicle's air conditioning system. The air conditioning system blows cooling (heating) air into the steering wheel, thus cooling (heating) it. The steering wheel assembly and the fixed intake assembly are connected by a connecting bushing, allowing the steering wheel assembly to rotate while the fixed intake assembly remains stationary. Furthermore, the first and second air chambers of the fixed intake assembly are much larger than the air inlet and outlet of the steering wheel assembly, enabling cooling (heating) even when the steering wheel is rotating. This design satisfies the need for small-angle steering and continuous cooling (heating) during normal driving. In winter, when the steering wheel temperature is too low, the heating wires on the steering wheel can be activated to heat it simultaneously, improving heating efficiency. When the temperature is suitable, the heating wires are deactivated, and heating is solely provided by the air conditioning system, further saving energy. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] like Figures 1 to 8As shown, a two-way temperature-adjustable steering wheel includes a steering wheel assembly 4, which includes a pivot 401. A central axle compartment 410 is fixedly connected above the pivot 401. A first annular groove 411 is fixedly connected to one end of the central axle compartment 410 and the pivot 401. An airbag chamber 409 is provided in the middle of the central axle compartment 410, and an airbag is installed in the airbag chamber 409 to improve safety. An air inlet 402 and an air outlet 406 are provided on the outer central compartment 410 of the airbag chamber 409. The air inlet 402 and the air outlet 406 are symmetrical about the pivot 401. Three connecting plates 407 are fixedly connected to the upper outer side of the airbag chamber 409. An air inlet pipe 404 and an air outlet pipe 405 are fixedly connected to one of the connecting plates 407. A steering wheel 403 is fixedly connected to the outer side of the three connecting plates 407. The steering wheel 403 is a hollow structure with a baffle 408 sealed inside. The air inlet pipe 404 and the air outlet pipe 405 are sealed to both sides of the steering wheel 403 respectively. The interior of the steering wheel 403 is connected to the air inlet 402 and the air outlet 406 respectively, so that cold air (hot air) is blown into the interior of the steering wheel 403 to achieve cooling (heating) of the steering wheel 403.

[0016] like Figures 3 to 5 As shown, a fixed air intake assembly 9 is nested around the pivot 401. The fixed air intake assembly 9 includes an air intake column 905, with a through pivot hole 902 in the middle of the air intake column 905. The pivot hole 902 is rotatably connected to the pivot 401, facilitating the rotation of the steering wheel assembly 4. A first air chamber 901 and a second air chamber 903 are formed on the air intake column 905 on both sides of the pivot hole 902. The bottom of the first air chamber 901 is sealed with a main air outlet pipe 908, and the bottom of the second air chamber 903 is sealed with a main air intake pipe 907. The main air intake pipe 907 is connected to the air outlet of the air conditioner, and the main air outlet pipe 908 is connected to the outside of the vehicle or discharged into the driver's cabin. The upper outer part of the intake column 905 is fixedly connected with a second annular groove 904, and the lower outer part of the intake column 905 is provided with a thread 906. The upper part of the intake column 905 abuts against the bottom of the central shaft compartment 410 and is fixed on the outside by the connecting bushing 8. When the steering wheel 403 is turned, there will be no gas leakage and there will be no situation where gas does not enter the intake port.

[0017] like Figure 6 and Figure 8As shown, a connecting bushing 8 is fixedly connected to the outer side of the intake column 905. The connecting bushing 8 has two semi-circular structures, and two threaded holes 801 are opened on each side of the flat end of the connecting bushing 8. A rubber gasket 802 is fixedly connected to the flat end of the connecting bushing 8. After the two connecting bushings 8 are connected, the rubber gasket 802 plays a sealing role to prevent cold (hot) air from leaking out. A first convex ring 803 and a second convex ring 804 are fixedly connected to the middle of the inside of the connecting bushing 8, respectively. A screw 6 is threaded to the threaded hole 801, and the two connecting bushings 8 are fixed together by the screw 6. The connection by the screw 6 facilitates subsequent maintenance and parts replacement. The first convex ring 803 is slidably connected to the first ring groove 411, and the second convex ring 804 is slidably connected to the second ring groove 904. The connecting bushing 8 serves to connect the steering wheel assembly 4 and the fixed intake assembly 9, and also allows the steering wheel assembly 4 to rotate.

[0018] The air intake 402 is located in the middle of the second air chamber 903, and the air outlet 406 is located in the middle of the first air chamber 901. The thickness of the baffle between the first air chamber 901 and the second air chamber 903 is greater than that of the air intake 402 and the air outlet 406. When the steering wheel 403 is slightly rotated (based on the static state of the steering wheel 403, rotating up and down within a range of -70° to 70°), during most of the rotation scenarios, the air intake 402 and the air outlet 406 are always located in the second air chamber 903 and the first air chamber 901, or part of the air intake 402 and the air outlet 406 are located on the baffle between the first air chamber 901 and the second air chamber 903, in which case air can still be intaked and exhausted, but the intake and exhaust volumes are reduced; when the steering wheel 403 is rotated at a large angle, the intake... There are two scenarios for air inlet 402 and air outlet 406. First, when air inlet 402 and air outlet 406 are rotated to the baffle between the second air chamber 903 and the first air chamber 901, air inlet 402 and air outlet 406 will briefly stop intake and exhaust. Second, after the steering wheel 403 is rotated several times, air inlet 402 and air outlet 406 will contact the first air chamber 901 and the second air chamber 903 respectively. In this case, air inlet 402 will exhaust air, and air outlet 406 will intake air, allowing the air to circulate within the steering wheel. Air will only enter through air inlet 402 and exit through air outlet 406 after the steering wheel 403 is returned to center.

[0019] A heating wire 3 is wound around the outside of the steering wheel 403. In cold winter weather, the heating wire 3 assists in heating, allowing the steering wheel 403 to heat up faster and improving heating efficiency. A protective sleeve 2, fixedly connected to the steering wheel 403, covers the connecting plate 407, making it more aesthetically pleasing and easier to grip. A heating wire guard assembly 5 is fixedly connected to one side of the central axle compartment 410. The heating wire guard assembly 5 is connected to the positive and negative terminals of the heating wire 3 to control its activation and deactivation. A protective cover plate 7 is also fixedly connected to the central axle compartment 410. An end cap 1 is fixedly connected to the outside of the airbag chamber 409 to protect the airbag inside. The end cap 1 is used to install the horn assembly.

[0020] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
