Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See attached document Figures 1 to 11 This invention relates to a steering wheel cover with a heating function.

[0021] The steering wheel cover includes a heated grip cover 1, a bracket 2, and a main unit 3. The heated grip cover 1 is fitted onto the outer surface of the steering wheel 100, and a heating unit 14 for generating heat is provided on the heated grip cover 1. The main unit 3 is detachably fixed to the heated grip cover 1 via the bracket 2, and the heating unit 14 is electrically connected to the main unit 3.

[0022] Specifically, the heating handle 1 is detachably connected to the bracket 2, and the main unit 3 is detachably connected to the heating handle 1. The heating handle 1 is provided with a first connector 16, which is electrically connected to the heating unit 14. The bracket 2 is provided with a second connector 26 and a third connector 25. The second connector 26 is used to mate with the first connector 16, and the second connector 26 and the third connector 25 are electrically connected. The first connector 16 is electrically connected to the second connector 26 when the bracket 2 and the heating handle 1 are assembled. The main unit 3 includes a housing 30 and a circuit board 32, an energy storage device, and a fourth connector 320 disposed on the housing 30. The energy storage device and the fourth connector 320 are both electrically connected to the circuit board 32. The fourth connector 320 is used to mate with the third connector 25, and the fourth connector 320 is electrically connected to the third connector 25 when the main unit 3 and the bracket 2 are assembled.

[0023] By configuring an energy storage device on the main unit 3 to power the heating unit 14, the steering wheel cover no longer needs to be powered by an external power cord or draw power from the car's cigarette lighter, reducing wiring in the vehicle, maintaining a clean and simple interior. Furthermore, the modular design allows users to easily install a heated steering wheel cover on the car's steering wheel 100 without requiring any destructive modifications to the vehicle. When the user no longer needs the steering wheel cover, it can be easily removed, facilitating easy removal and replacement and reducing maintenance costs.

[0024] In one embodiment, the heated steering wheel cover 1 can be ring-shaped, C-shaped, or similar. The heated steering wheel cover 1 is flexible; that is, when not on the steering wheel 100, it can be laid flat as a cuboid. When installed on the steering wheel 100, the upper and lower surfaces of the heated steering wheel cover 1 are secured with Velcro or fasteners to wrap around the outer surface of the steering wheel 100. Alternatively, the heated steering wheel cover 1 itself is elastic; that is, when not installed on the steering wheel 100, it is tubular with a C-shaped cross-section, allowing the user to open the C-shaped opening and place the heated steering wheel cover 1 on the steering wheel 100.

[0025] In one embodiment, the heating unit 14 can be a carbon nanotube heating element. This heating unit 14 has the advantages of rapid heating and low energy consumption, thereby more quickly meeting the user's temperature needs and improving the battery life of the energy storage device. Furthermore, the carbon nanotube heating element provides uniform heating, resulting in a more stable temperature distribution on the outer surface of the heated steering wheel cover 1, preventing localized overheating and improving comfort and safety. Specifically, the heating unit 14 can be a shaped carbon nanotube heating element, i.e., the heating unit 14 is arc-shaped to fit the heated steering wheel cover 1. Alternatively, the heating unit 14 can be a flexible carbon nanotube heating element, i.e., the heating unit 14 can be bent to fit the steering wheel 100. Of course, in other embodiments, the heating unit 14 can also be a silicone heating element, a resistance wire heating element, etc.

[0026] The heated handle cover 1 can be made of materials such as plush, silicone, or genuine leather to balance aesthetics, feel, and warmth, thus meeting the needs of different users.

[0027] In this embodiment, the heating sleeve 1 is provided with a temperature detection unit 15 for detecting temperature. The temperature detection unit 15 is electrically connected to the first connector 16. The circuit board 32 controls the temperature of the heating unit 14 according to the temperature signal fed back by the temperature detection unit 15, so as to keep the temperature of the heating sleeve 1 at a constant temperature. Specifically, the temperature detection unit 15 can be a thermistor, temperature sensor, etc.

[0028] The outer casing 30 is equipped with one or more operating units 321 electrically connected to the circuit board 32. The operating units 321 can be touch buttons or mechanical buttons, etc. When operating the operating units 321, the user can start or stop the main unit 3, or switch the heating temperature levels of the heating unit 14. For example, there are three heating temperature levels: level one is 40 degrees Celsius, level two is 45 degrees Celsius, and level three is 50 degrees Celsius. In actual product manufacturing, the heating temperature levels and their corresponding temperatures can be customized by the manufacturer, or the user can later adjust the heating temperature of the heating unit 14 through the operating units 321 to meet different temperature requirements of the heated grip 1. Furthermore, the operating units 321 can also be used to schedule the heating time of the heating unit 14. For example, if the user schedules it for 2 PM, the main unit 3 will activate the heating unit 14 at 2 PM to ensure the user has a comfortable heated grip 1 when getting into the vehicle. Furthermore, the operating unit 321 can also set the heating duration of the heating unit 14. For example, if the user's vehicle usage time is 2 hours, the heating unit 14 can continuously heat for 2 hours. After two hours, it can automatically stop heating to prevent the heating unit 14 from continuing to heat due to the user forgetting to turn off the host 3 after the trip.

[0029] In one embodiment, the energy storage device includes a rechargeable battery. The housing 30 is provided with an external power source and a charging interface 34 for charging external devices. The charging interface 34 is electrically connected to a circuit board 32. When the charging interface 34 is connected to an external power source via a power cord, the power supplied can charge the rechargeable battery 33 via the circuit board 32. When the charging interface 34 is connected to external devices such as mobile phones, tablets, or smartwatches via a charging cable, the charge from the rechargeable battery 33 is transferred to the external device via the circuit board 32, the charging interface 34, and the charging cable. This enables the steering wheel cover in this embodiment to charge external devices, expanding its functionality and providing more charging interfaces 34 for users to use, thus meeting the needs of multiple users charging simultaneously.

[0030] In one embodiment, the charging interface 34 supports fast charging, meaning that the charging interface 34 can be connected to a power source with fast charging power and can output fast charging power to external devices. Specifically, the circuit board 32 integrates a fast charging module for supporting fast charging, such as a fast charging module that supports charging and output power of 60W, 100W, etc. The fast charging module is electrically connected to the charging interface 34, which is a TYPE-C interface.

[0031] When the power input to charging interface 34 is a fast-charging power source, the fast-charging module built into circuit board 32 dynamically identifies and matches the input voltage and current with the protocol, thereby enabling high-power charging of rechargeable battery 33 while ensuring safety. This fast-charging module effectively reduces energy conversion loss and heat accumulation by adjusting the voltage and current in real time during the charging process, improving energy transfer efficiency and allowing rechargeable battery 33 to obtain sufficient charge in a shorter time, reducing charging waiting time. When the external device connected to charging interface 34 supports fast charging, the fast-charging module can automatically identify the charging protocol of the external device and switch to output mode, outputting a matched high-power power supply to the external device through charging interface 34, thus achieving bidirectional fast charging between different devices. This structure achieves fast charging identification and power scheduling for both input and output through a single interface, optimizing the energy distribution path of the power management circuit, improving overall power utilization, and reducing intermediate power conversion losses in traditional dual-interface structures. Furthermore, because the fast charging module enables intelligent regulation of energy flow, this device can be used flexibly in various scenarios such as vehicle-mounted, outdoor emergency, and power sharing, significantly improving the applicability and energy efficiency of the device and demonstrating system-level technological progress.

[0032] In one embodiment, two rechargeable batteries 33 are arranged side-by-side, left and right, both located behind the circuit board 32, to achieve a reasonable distribution of the rechargeable batteries 33 and the circuit board 32. Of course, in other embodiments, the number of rechargeable batteries 33 may be one, three, or other types. The rechargeable batteries 33 may be lithium batteries, AA rechargeable batteries, AAA rechargeable batteries, etc.

[0033] In one embodiment, the rechargeable battery 33 has a capacity of 5000mAh to 20000mAh to charge external devices.

[0034] Of course, in other embodiments, the energy storage device may also be a dry cell battery, that is, a non-rechargeable battery, and in this embodiment, the housing 30 is provided with a removable cover at the position corresponding to the dry cell battery so as to replace the dry cell battery.

[0035] In one embodiment, a display 31 is provided on the housing 30. The display 31 is electrically connected to the circuit board 32. The display 31 is used to display the power of the energy storage device, the heating temperature of the heating unit 14, the working mode of the host 3, etc., so that the user can understand the power of the energy storage device and better control the heating temperature of the heating unit 14.

[0036] In one embodiment, the steering wheel cover further includes a pin 5. A first protrusion 11 is connected to the heated steering wheel cover 1, and a first insertion hole 12 is formed on the first protrusion 11. A second insertion hole 21 is formed on the bracket 2. When the bracket 2 is assembled with the heated steering wheel cover 1, the pin 5 passes through the first insertion hole 12 and the second insertion hole 21 to securely connect the bracket 2 to the heated steering wheel cover 1. Furthermore, when the user pulls the pin 5 out of the first insertion hole 12 and the second insertion hole 21, the bracket 2 can be detached from the heated steering wheel cover 1, thus enabling the bracket 2 to be detached from the heated steering wheel cover 1.

[0037] In one embodiment, the cross-section of the heated steering wheel cover 1 is a C-shape with the first opening 13 facing downwards. The C-shaped heated steering wheel cover 1 makes it easy for the user to put the heated steering wheel cover 1 on the steering wheel.

[0038] The first protrusion 11 includes a front protrusion 112 and a rear protrusion 111, which are distributed on both sides of the first opening 13. The second insertion hole 21 is located between the front protrusion 112 and the rear protrusion 111. That is, when the bracket 2 is assembled with the heating handle 1, the heating handle 1 is at least partially placed between the front protrusion 112 and the rear protrusion 111. The end of the pin 5 is provided with a first locking block 55. The pin 5 passes through the first insertion hole 12 and the second insertion hole 21 of the front protrusion 112 and the second insertion hole 21 of the rear protrusion 111 in sequence. The first locking block 55 is located on the side of the rear protrusion 111 away from the front protrusion 112, so as to stably fix the bracket 2 on the heating handle 1.

[0039] To further improve the stability of the assembly between the bracket 2 and the heating sleeve 1, there are two front protrusions 112, which are spaced apart. There are also two rear protrusions 111, which are spaced apart. Of course, in other embodiments, the number of front protrusions 112 and rear protrusions 111 can be one, three, or other similar.

[0040] In one embodiment, the pin 5 includes a head 51 and a plug portion 52 connected to the head 51. There are two first locking blocks 55, distributed on both sides of the plug portion 52. A first locking groove 54 is provided on both sides of the plug portion 52. The first locking blocks 55 are located on the side of the first locking groove 54 away from the head 51. A portion of the rear protrusion 111 is placed within the first locking groove 54. The plug portion 52 passes through the first insertion hole 12 and the second insertion hole 21 of the front protrusion 112 and the second insertion hole 21 of the rear protrusion 111. The head 51 is located on the side of the front protrusion 112 away from the rear protrusion 111. A clearance gap 53 is provided in the middle of the plug portion 52, which allows the plug portion 52 to be divided into two halves. The clearance gap 53 also provides clearance space for the first locking blocks 55 when the plug portion 52 passes through the first insertion hole 12 and the second insertion hole 21, facilitating the passage of the plug portion 52. Furthermore, the pin 5 is flat to increase the mating area between the bracket 2 and the heating handle 1, thereby improving the firmness of the assembly between the bracket 2 and the heating handle 1.

[0041] Of course, in other embodiments, the pin 5 can also be a screw, and the first locking block 55 can be a nut, etc., which can also achieve the fixed assembly of the bracket 2 and the heating sleeve 1.

[0042] In one embodiment, the steering wheel cover also includes a strap 4. The bracket 2 has strap holes (not shown in the figure). The strap 4 passes through the strap holes to fix the bracket 2 to the steering wheel 100. Using the strap 4, the bracket 2 can be detachably fixed to the steering wheel 100, thus also enabling the bracket 2 and the heated steering wheel cover 1 to be used detachably together. This embodiment, combined with the pin 5 to fix the bracket 2 and the heated steering wheel cover 1, can effectively improve the stability of the fixation between the bracket 2 and the heated steering wheel cover 1, ensuring that the bracket 2 and the main unit 3 are stable and do not shift during use, avoiding driving safety hazards.

[0043] In one embodiment, the strap hole is a second insertion hole 21 to reduce the volume of the bracket 2. Of course, in other embodiments, the strap hole and the second insertion hole 21 may be separate. The strap 4 may be a plastic or metal cable tie, a rope that fixes the bracket 2 to the steering wheel by knotting, or a Velcro cable tie that fixes the bracket 2 to the steering wheel, etc.

[0044] In one embodiment, the bracket 2 is provided with a slider 22, and the outer casing 30 is provided with a groove 38 that cooperates with the slider 22. A third connector 25 is disposed on the slider 22, and a fourth connector 320 is located on the groove 38. The slider 22 is placed in the groove 38 when the main unit 3 is assembled with the bracket 2. By using the groove 38 and the slider 22 to cooperate, the main unit 3 and the bracket 2 can be detachably connected. Furthermore, distributing the third connector 25 on the slider 22 and the fourth connector 320 on the groove 38 can effectively ensure a stable connection between the third connector 25 and the fourth connector 320, preventing them from detaching. The bracket 2 and the outer casing 30 are limited by a snap-fit ​​mechanism in the direction of sliding along the groove 38 and the slider 22 to prevent the main unit 3 from falling off the bracket 2, thereby improving the stability of the assembly of the main unit 3 and the bracket 2.

[0045] In one embodiment, there are two sliders 22, which are spaced apart. There are two grooves 38, which are also spaced apart. The third connector 25 includes a first connecting terminal 251 and a second connecting terminal 252. The first connecting terminal 251 and the second connecting terminal 252 are located on both sides of the second connector 26. Each of the first connecting terminal 251 and the second connecting terminal 252 corresponds to a slider 22. A wiring cavity 29 is provided in the bracket 2. The first connecting terminal 251 and the second connector 26 are electrically connected through a first conductive line or a first PCB board. The second connecting terminal 252 and the second connector 26 are electrically connected through a second conductive line or a second PCB board. The fourth connector 320 includes a third connector 323 that mates with the first connector 251 and a fourth connector 322 that mates with the second connector 252. Each of the third and fourth connectors 323 and 322 corresponds to a groove 38. Both the third and fourth connectors 323 and 322 are electrically connected to the circuit board 32. The third connector 323 is used for power transmission, and the fourth connector 322 is used for transmitting the temperature signal generated by the temperature detection unit 15. By configuring two spaced sliders 22, the connection between the bracket 2 and the host 3 can be made more stable. Furthermore, dividing the third connector 25 into a first connector 251 and a second connector 252, each corresponding to a slider 22, reduces the size of the sliders 22.

[0046] Specifically, slider 22 protrudes from the bottom of bracket 2. One slider 22 has a first receiving cavity 222 for accommodating the first connecting terminal 251, which communicates with the wiring cavity 29. The other slider 22 has a second receiving cavity 221 for accommodating the second connecting terminal 252, which also communicates with the wiring cavity 29. The bottom of bracket 2 also has a second protrusion 23, which has a second receiving cavity 221 for accommodating the second connector 26, which communicates with the wiring cavity 29, so as to facilitate electrical connection between the first connecting terminal 251 and the second connector 26, and to facilitate electrical connection between the second connecting terminal 252 and the second connector 26. The opening directions of the first and second connecting terminals are opposite to the opening direction of the second connector.

[0047] The second protrusion 23 has a second slot 24, and the top surface of the outer casing 30 has a U-shaped clearance hole 361. A spring piece 362 is formed in the outer casing 30 through the clearance hole 361. The spring piece 362 has a second locking block 363 that cooperates with the second slot 24. The second locking block 363 is placed in the second slot 24 when the bracket 2 and the main unit 3 are assembled, so that the bracket 2 and the main unit 3 are locked together by a latch in the direction of sliding along the slide groove 38 and the slider 22. Of course, in other embodiments, the latch between the bracket 2 and the main unit 3 can also be provided between the slide groove 38 and the slider 22 or on the outer surface of the bracket 2 and the outer casing 30.

[0048] Of course, in other embodiments, the third connector 25 may not be divided into a first connecting terminal 251 and a second connecting terminal 252, and the fourth connector 320 may not be divided into a third connecting terminal 323 and a fourth connecting terminal 322. That is, the third connector 25 may be configured with a slider 22, and the fourth connector 320 may be configured on a groove 38 corresponding to the slider 22 with the third connector 25. The groove 38 may also be configured on the bracket 2, and the slider 22 may be configured on the host 3.

[0049] In one embodiment, plug-in interfaces are used between the first connector and the second connector, between the first connection terminal and the third connection terminal, and between the second connection terminal and the fourth connection terminal to form a stable power or signal path. Of course, in other embodiments, contact connections can also be used between the first connector and the second connector, between the first connection terminal and the third connection terminal, and between the second connection terminal and the fourth connection terminal to achieve the same power or signal path.

[0050] In the above embodiment, the bracket 2 includes a base 28 and a cover plate 27 connected to the base 28 to form a wiring cavity 29. The slider 22 and the second protrusion 23 are both located at the bottom of the base 28. The base 28 and the cover plate 27 can be connected by means of snap-fit, screws, ultrasonic pressing, etc.

[0051] Both the bracket 2 and the outer shell 30 are curved. The curvature of the bracket 2 and the outer shell 30 are consistent with the curvature of the steering wheel 100, so that when the bracket 2 and the main unit 3 are installed on the steering wheel 100, the visual effect is more harmonious and the space on the steering wheel 100 is more reasonable.

[0052] The outer casing 30 includes a front casing 35 and a rear casing 36 connected to the front casing 35 to form a receiving cavity 37. The circuit board 32 and rechargeable battery 33 are both disposed within the receiving cavity 37. The sliding groove 38, the clearance through hole 361, and the charging interface 34 are all located on the rear casing 36. Specifically, the front casing 35 and the rear casing 36 are connected by snaps, screws, ultrasonic pressing, or other methods. The display 31, circuit board 32, and rechargeable battery 33 are arranged sequentially along the thickness of the steering wheel. The third connector and the fourth connector terminal 322 are both located above the rechargeable battery 33, a reasonable distribution that effectively reduces the size of the main unit 3. Of course, in other embodiments, the rechargeable battery 33 may also be located below or above the circuit board 32.

[0053] In one embodiment, the housing 30 is also provided with a wireless module (not shown in the figure) that is electrically connected to the circuit board 32. The wireless module can communicate with external devices, that is, through external devices, the host 3 can be remotely controlled to drive the heating unit 14 to heat up, and the heating time and temperature of the heating unit 14 can be scheduled, which improves the user experience and makes it easier for users to use in winter.

[0054] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0055] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
