Description

Technical Field

[0001] This utility model relates to steering wheel auxiliary tools, specifically to a steering wheel quick release device. Background Technology

[0002] In the automotive industry, quick-release steering wheels are widely used to facilitate drivers getting in and out of vehicles or for anti-theft purposes.

[0003] Traditional steering wheel quick-release mechanisms typically connect and disconnect via a steel ball in the female connector mating with a slot in the male connector. However, existing technology has several shortcomings:

[0004] Firstly, the space for the horn button on the steering wheel quick release mechanism is quite large. Installing the corresponding horn button separately would not only waste installation space but also fail to make full use of the area.

[0005] Secondly, when a car crashes out of control, there may be a critical situation where the doors and windows cannot be opened. However, the car is often not equipped with a window breaker, especially the steering wheel quick release mechanism, which does not have a window-breaking function, making it difficult for the people inside the car to save themselves and escape.

[0006] Third, when a car breaks down at night, it needs to send out a distress signal. However, most vehicles lack lighting distress devices, and such devices are rarely installed in the steering wheel quick release mechanism, which makes it difficult for the people inside the car to get help in a timely manner.

[0007] Therefore, there is an urgent need to improve the traditional steering wheel quick release mechanism to enhance vehicle safety and emergency response capabilities. Utility Model Content

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0040] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0041] Example 1: The specific structure of this utility model is as follows:

[0042] Please refer to the appendix. Figure 1-7The present invention provides a steering wheel quick release device, comprising a flange 5 fixed to the center area of ​​the steering wheel and a quick release mechanism detachably connected to the flange 5. The quick release mechanism has a horn mounting area. The steering wheel quick release device also includes a window breaker, which is disposed in the horn mounting area and has a space for pressing the horn.

[0043] The window breaker includes two semi-circular structural members 12, with their ends interlocked.

[0044] The first end of the first semi-circular structural component is equipped with a window-breaking post 125, which is used to break the car window to facilitate the escape of people inside the vehicle.

[0045] The second end of the first semi-circular structural component is provided with a protruding magnet 130 and a first groove. An LED light panel 132 is provided inside the first semi-circular structural component. One side of the LED light panel 132 is provided with LED beads 133. The side of the first semi-circular structural component that emits light opposite the LED light panel 132 is a transparent plate. When the LED beads 133 are powered on, they emit a distress signal light consisting of three short, three long, and three short blasts, making it easy for passersby or nearby personnel to spot and receive timely assistance.

[0046] The first end of the second semi-circular structural member has a post hole 126 for the window-breaking post 125 to enter and which matches the outer rafter contour of the window-breaking post 125. The second end has a slot 129, and an iron sheet 128 is fixed to the bottom surface of the slot 129. The slot cavity of the slot 129 matches the outer rafter contour of the magnet 130. The second end of the second semi-circular structural member also has a second groove. The first groove and the second groove are arranged opposite to each other, and the cavity formed after the first groove and the second groove are connected contains a spring-shaped wire 131. The first end of the wire 131 is electrically connected to the LED light board 132. The interior of the second semi-circular structural member contains a battery pack. The battery pack is composed of multiple rechargeable batteries 127 forming an arc-shaped structure. The battery pack is connected to the second end of the wire 131 through a power supply board. The wire 131 of this utility model is a high-strength tensile-resistant wire to prevent the driver from breaking the wire 131 under tension.

[0047] The power supply board is equipped with a power switch 121, which is visible within the inner ring of the second semi-circular structure. A USB charging port 122 is located on the bottom surface of the second semi-circular structure. The USB charging port 122 is electrically connected to the power supply board, and the connection point of the USB charging port 122 is sealed with adhesive for waterproofing. The power switch 121 is used to control the on / off state of the LED light panel 132.

[0048] The upper surfaces of the first and second semicircular structural components are provided with grooves 123. The grooves 123 are provided with lifting posts 124 that are not higher than the upper surfaces. The lifting posts 124 are designed to facilitate the outward lifting of the two semicircular structural components, making it easier for the driver to operate quickly.

[0049] The window breaker consists of two semi-circular structural components 12, cleverly installed in the horn mounting area of ​​the quick-release mechanism, making full use of unused space without affecting the normal pressing operation of the horn. The two semi-circular structural components 12 are interlocked at their ends to form a complete functional unit. This connection method not only facilitates installation and disassembly but also ensures the stability of the structure during normal use, while providing protection and support for the internal components.

[0050] The first end of the first semi-circular structural component is equipped with a window-breaking post 125, which is the core component for the window breaker to achieve emergency escape. When the vehicle encounters an emergency and the doors and windows cannot be opened normally, the driver can quickly remove the two semi-circular structural components from the horn mounting area via the lifting post 124. The lifting post 124 is hidden within the recess 123, which does not affect the overall appearance and operation of the steering wheel quick-release device, and is easy to grab quickly in an emergency. After removal, the driver can hold the window breaker and use the sharp end of the window-breaking post 125 to strike the edge or corner of the window glass. The window-breaking post 125 is made of high-strength material, which can concentrate the external force at one point and generate a huge impact force instantly, thereby shattering the window glass and opening an escape route for the occupants of the vehicle.

[0051] The first semicircular structure houses an LED light panel 132, with LED beads 133 on one side serving as the key to enabling nighttime distress signals. The battery pack inside the second semicircular structure consists of multiple rechargeable batteries 127 arranged in an arc shape. It is electrically connected to the LED light panel 132 via a power supply board and spring-shaped wires 131, forming a complete power supply circuit. When the vehicle breaks down or encounters danger at night and needs to call for help, the driver can control the power supply board to supply power to the LED light panel 132 via a switch 121 located in a visible position on the inner ring of the second semicircular structure. At this time, the LED beads 133, after being powered on, emit a universally recognized distress signal light pattern of "three short, three long, three short" according to a preset program. The side of the first semicircular structure that emits light opposite the LED light panel 132 is transparent, ensuring clear and effective light transmission, attracting the attention of passersby or nearby rescue forces, and increasing the chances of timely assistance.

[0052] The connection method of the two semi-circular structural components ensures the overall stability of the window breaker. The protruding magnet 130 at the second end of the first semi-circular structural component attracts the iron plate 128 on the bottom surface of the groove 129 at the second end of the second semi-circular structural component. At the same time, the groove cavity of the groove 129 precisely matches the outer contour of the magnet 130, making the two semi-circular structural components tightly connected together and preventing loosening and separation during normal use or emergency operation. The spring-shaped wire 131 housed after the first and second grooves meet has good flexibility and strength, ensuring normal circuit continuity during the connection and separation of the two semi-circular structural components, and preventing easy damage due to pulling by the driver under tension, thus ensuring the stability of the power supply to the LED light panel 132.

[0053] The USB charging port 122 located on the bottom surface of the second semi-circular structural component is electrically connected to the power supply board for charging the battery pack. Its connection point is sealed with waterproof adhesive to effectively prevent damage to the charging port and internal circuitry from splashes of water or humid environments during vehicle operation, ensuring charging safety. When the battery pack is low on power, it can be connected to an external power source (such as a car charger or power bank) via a standard USB charging cable to replenish the battery pack, ensuring the window breaker's nighttime emergency call function is always available.

[0054] Example 2:

[0055] This utility model adds a window breaker while retaining the original function of the steering wheel quick release mechanism.

[0056] The flange 5 has an annular panel 53 and a cylindrical portion 54 connected to the inner ring of the annular panel 53. The outer circumferential surface of the cylindrical portion 54 is provided with a plurality of circular grooves along the same circular path. The opening of the cylindrical portion 54 is also provided with a right-angle groove 55, which is used to insert a ring body 7. The inner ring of the ring body 7 has a convex ring 71 to support the second spring 8.

[0057] The quick-release mechanism includes a main body 1, a movable sleeve 4, a first spring 3, and several ball bearings 10.

[0058] The main body 1 has multiple outer steps and multiple inner steps. Multiple through holes 101 with a wider outer surface and a narrower inner surface and on the same circular path are provided along the side circumference of the outer steps. The inner steps are equipped with a horn key installer 2. The horn key installer 2 consists of two annular bodies of different sizes. The outer ring of the smaller annular body is connected to the inner ring of the larger annular body, and a step groove is formed at the connection. The upper ring surface of the larger annular body is fixed to the inner steps by screws. The upper ring surface of the larger annular body is used to place a window breaker.

[0059] like Figure 2 As shown, Figure 2 yes Figure 1The cross-sectional view shows that the upper surface of the large ring is provided with a USB power supply port 13, which can be quickly connected to the USB charging interface 122, enabling the vehicle battery to supply power to the rechargeable battery 127 and preventing the rechargeable battery 127 from being damaged due to prolonged lack of charging. The inner ring of the large ring is provided with a cable 14 that connects to the USB charging interface 122, and this cable 14 is quickly connected to the speaker's power supply line via a quick connector.

[0060] A number of balls 10 are disposed in the gap, and a portion of the balls pass through the through hole 101 and the balls 10 are restricted by the through hole 101.

[0061] The movable sleeve 4 is fitted onto the outer step and has an upward-facing inner circular groove. A gap is formed between the inner circumferential surface of the movable sleeve 4 facing the outer step and the side circumferential surface of the outer step. The size of the gap satisfies the following conditions: when the movable sleeve 4 rises to its top, the ball bearing 10 can disengage from the through hole 101 without disengaging from the gap; and when the movable sleeve 4 descends, it can push the ball bearing 10 into the through hole 101, so that part of the ball bearing 10 pushes into the circular groove. The gap includes a first gap and a second gap. The inner circumferential surface of the movable sleeve 4 has an arc-shaped inner circumferential surface 102 and an inner circular annular surface near the lower opening. A slope 103 is formed between the arc-shaped inner circumferential surface 102 and the inner circular annular surface. The first gap is formed between the arc-shaped inner circumferential surface 102 and the outer circumferential surface of the cylindrical portion 54; the second gap is formed between the inner circular annular surface and the outer circumferential surface of the cylindrical portion 54; the first gap is smaller than the second gap. The first end of the first spring 3 abuts against the outer step, and its second end abuts against the inner groove of the movable sleeve 4; as follows Figure 2 As shown, the movable sleeve 4 can move up and down. When the movable sleeve 4 is lifted, the ball bearing 10 will be released. After the ball bearing 10 is released, it will no longer be in contact with the groove on the cylindrical part 54. Therefore, the main body 1 can be removed from the cylindrical part 54, which is the purpose of quick release of the steering wheel.

[0062] When you want to lock the steering wheel, simply lift and hold the movable sleeve 4, put the main body 1 over the cylindrical part 54, and then release the movable sleeve 4. The movable sleeve 4 is held in place by the first spring 3. Rotate the main body 1 so that each ball 10 enters the corresponding groove. Finally, the movable sleeve 4 is reset, and the ball 10 locks the main body 1 and the cylindrical part 54.

[0063] In summary, this utility model steering wheel quick release device has an emergency escape function: the window breaker is set in the horn installation area, which is conspicuous and easy to access. When the vehicle encounters an emergency and the doors and windows cannot be opened, the driver can quickly take out the window breaker and use the window breaker to break the window to achieve a rapid escape, which significantly improves the survival rate of the people in the vehicle in dangerous situations.

[0064] This utility model steering wheel quick release device features a nighttime emergency call function: the built-in LED light panel and LED beads of the window breaker can emit standard emergency signal lights through the control of the on / off switch. When a car breaks down at night, it can effectively attract attention from the outside world and increase the chance of being rescued, filling the gap in the nighttime emergency call function of traditional steering wheel quick release devices.

[0065] This utility model of a steering wheel quick-release device integrates space utilization and functionality: it makes full use of the unused space in the horn installation area and integrates a window breaker and a light distress signal device into the steering wheel quick-release device. Without affecting the original function of the steering wheel quick-release device, it integrates multiple practical functions, thereby improving the practicality and multifunctionality of the product.

[0066] This utility model steering wheel quick-release device offers convenient charging and a secure connection: the window breaker's battery pack is charged via a USB charging port, and the waterproof seal design ensures charging safety; the two semi-circular structural components are connected by a magnet and an iron sheet, and a column hole and a window breaker column, ensuring the window breaker's structure is stable and not easily loosened during use. At the same time, the spring-shaped wire design also ensures the stability of the circuit connection.
