[0034] In order to enable those skilled in the art in the technical field to which the present application pertains to more clearly understand the present application, the technical solution of the present application will be described in detail below with reference to the drawings and through specific embodiments.

[0035] During the driving or parking process of a vehicle, it may be subject to side impacts. If the impact reaches the central position of the rim, it is very likely that the universal joint of the steering system will malfunction, and the hard points of the chassis and the half shaft may also be impacted.

[0036] Based on the above - mentioned disadvantages in the prior art, the present invention provides an anti - collision device, a wheel and a vehicle, which can effectively protect the output end of the half shaft during side impacts and avoid damage to the steering knuckle and chassis hard points.

[0037] Embodiment 1

[0038] The embodiment of the present application provides an anti - collision device for protecting a wheel, which can form a buffer after a side impact of the wheel to achieve effective protection.

[0039] Please refer to Figures 1 to 6 , the anti - collision device provided by the embodiment of the present application includes a protection part 1 and an inflatable part 2. An installation part 11 and a connection part 12 for connecting the wheel 3 are provided on one side of the protection part 1 close to the wheel 3; the inflatable part 2 is installed on the installation part 11. The inflatable part 2 is installed between the protection part 1 and the wheel 3. The protection part 1 hides the inflatable part 2, making the wheel 3 more beautiful, and the protection part 1 also provides an installation position for the inflatable part 2. During a side impact, the protection part 1 is first impacted. The impacted protection part 1 moves towards the wheel 3, reducing the gap between the protection part 1 and the wheel 3. The inflatable part 2 will be activated to inflate, thereby buffering and absorbing the collision energy, protecting the wheel 3 and the half shaft connected to the wheel 3, and avoiding damage to the steering knuckle and chassis hard points; if the object colliding with the wheel 3 is a cyclist, after the inflatable part 2 inflates, it can also protect the cyclist and avoid the instantaneous impulse of the collision from causing the cyclist to rebound at high speed and cause injury.

[0040] In some embodiments, a protrusion 13 is provided on one side of the protection member 1 close to the wheel 3. The root of the protrusion 13 or the inner wall of the installation cavity of the protrusion 13 forms an installation portion 11, and the end of the protrusion 13 forms a connection portion 12 for being embedded in the groove 31 of the wheel 3. That is to say, in certain embodiments, the protrusion 13 may be sequentially provided with the installation portion 11 and the connection portion 12 along the direction away from the protection member 1. The end of the protrusion 13 close to the protection member 1 forms the installation portion 11, and the end of the protrusion 13 away from the protection member 1 forms the connection portion 12. The inflatable member 2 is connected to the outside of the protrusion 13. At this time, the inflatable member 2 may be annular and sleeved on the root of the protrusion 13. The inflatable member 2 is arranged between the wheel 3 and the body of the protection member 1; the inflatable member 2 may also be square and directly connected to the root of the protrusion 13. At this time, the inflatable member 2 can protect the half shaft of the wheel 3 and the surrounding area in the radial direction; the inflatable member 2 can be adhered to the installation portion 11 of the protrusion 13; the end of the protrusion 13 is embedded in the groove 31 of the wheel 3. Specifically, the end of the protrusion 13 can press against the end of the half shaft connected to the wheel 3, and the connection is more stable. In other embodiments, the protrusion 13 may be provided with an installation cavity. The inner wall of the installation cavity forms the installation portion 11 of the inflatable member 2. The inflatable member 2 installed in the installation cavity is matched with the position of the end of the half shaft, and can more directly protect the half shaft connected to the wheel 3. In other embodiments, the inflatable member 2 can also be installed in both the installation cavity of the protrusion 13 and the root of the protrusion 13 to provide multi-faceted protection for the wheel 3.

[0041] In some embodiments, both the installation portion 11 and the connection portion 12 may be protrusions 13 provided on one side of the protection member 1 close to the wheel 3. The two protrusions 13 are distributed at intervals. That is to say, one protrusion 13 is used for being embedded in the groove 31 of the wheel 3, and the other protrusion 13 is used for installing the inflatable member 2; the other protrusion 13 may also be provided with an installation cavity, and the outside and / or the inner wall of the installation cavity of the other protrusion 13 are provided with the inflatable member 2; in other embodiments, a plurality of protrusions 13 serving as the installation portion 11 may also be provided. The protrusions 13 serving as the installation portion 11 are equally spaced in the outer periphery with the protrusion 13 serving as the connection portion 12 as the center.

[0042] In some embodiments, a plurality of inflatable members 2 may be provided. The plurality of inflatable members 2 are connected to the installation portion 11; the connection portion 12 is provided with a central hole. The setting of the central hole can reduce the strength of the connection portion 12 and is easily damaged during a side impact, triggering the inflation of the inflatable member 2. In other embodiments, the central hole may form the above-mentioned installation cavity to facilitate the installation of the inflatable member 2 into the installation cavity. The number of the inflatable members 2 can be selected according to requirements and is not limited herein.

[0043] In some embodiments, the anti-collision device further includes an inflation mechanism, a controller, and a pressure sensor 5. The inflation mechanism is disposed inside the inflatable member 2 or communicates with the inner cavity of the inflatable member 2. When the inflation mechanism is disposed inside the inflatable member 2, the inflation mechanism can generate gas through a chemical reaction to inflate the inflatable member 2, or the inflation mechanism can be an inflator. When the inflation mechanism communicates with the inner cavity of the inflatable member 2, it can fill the inflatable member 2 with gas after executing the inflation command of the controller, causing the inflatable member 2 to expand. The positional relationship between the inflation mechanism and the inflatable member 2 is not limited. The inflation mechanism can be a gas generator, such as a dual-stage gas generator. Generally, there are dual-stage gas pyrotechnic, dual-stage gas storage, and "force-increasing" gas generators. The selection of the inflation mechanism can refer to the disclosure of the prior art, and the specific content is not limited. The controller is electrically connected to the inflation mechanism to control the inflation mechanism to inflate the inflatable member 2. The pressure sensor 5 is electrically connected to the controller to transmit the pressure generated during a side collision to the controller. The controller determines whether to control the inflation mechanism to inflate the inflatable member 2 based on the pressure value. When the pressure value generated by the collision is small, the inflation mechanism does not need to be opened to inflate the inflatable member 2. When the pressure value generated by the collision exceeds the threshold, the controller controls the inflation mechanism to open and inflate the inflatable member 2.

[0044] In some embodiments, a plurality of pressure sensors 5 are provided. The plurality of pressure sensors 5 are spaced apart on the side of the protective member 1 close to the wheel 3 to detect the collision pressure at multiple positions outside the wheel 3 and transmit the detected pressure value to the controller for pressure value analysis by the controller. The number of pressure sensors 5 can be determined as needed and is not limited herein. The pressure sensors 5 can be arranged in one-to-one correspondence with the inflatable members 2, and the inflatable member 2 corresponding to the position where the pressure sensor 5 detects a collision is inflated for protection.

[0045] In some embodiments, the protective member 1 can be provided with a plurality of connecting columns 14 for connecting to the wheel 3. The protective member 1 is connected to the wheel 3 through the connecting columns 14. Specifically, the connecting columns 14 can be snap-fitted onto the rim 32, so that the anti-collision device and the rim 32 form an integral body, which is beautiful and generous. The connecting columns 14 are equidistantly arranged around the connecting portion 12 with a gap, with the connecting portion 12 as the center, so that the protective member 1 forms a centrosymmetric shape, which is convenient for mold opening.

[0046] Specifically, in some embodiments, the inflatable member 2 is made of a flexible material, and the inflatable member 2 can be at least one of an air curtain and an airbag. When the inflatable member 2 is an air curtain, the air curtain can be wound around the root of the protrusion 13 and then tied with a rope; when the inflatable member 2 is an airbag, the inflatable member 2 can be disposed in the installation cavity of the protrusion 13 or connected to the root of the protrusion 13. The protection member 1 can be a protective cover or a protective hood and is obtained by injection molding. A pattern can be provided on the side of the protection member 1 away from the wheel, and the texture of the protection member can also be designed according to the appearance of the wheel rim, so that the protection member is integrated with the wheel, enhancing the aesthetic feeling.

[0047] The working process of the anti-collision device provided by the embodiment of the present application is as follows:

[0048] When the vehicle is driving or parked and is impacted from the side, the protection member 1 moves towards the wheel 3 under the impact and generates extrusion with the wheel 3. The pressure sensor 5 detects the pressure, and the controller obtains the pressure value detected by the pressure sensor 5. The controller compares the pressure value with a threshold value. If the pressure value exceeds the threshold value, the controller determines that the wheel 3 needs to be protected. At this time, the controller sends a signal to the inflation mechanism to control the inflation mechanism to open and inflate the inflatable member 2, so that the inflatable member 2 becomes larger, buffers and absorbs energy to protect the vehicle body; if the pressure value does not exceed the threshold value, the controller determines that the side impact force is small and will not cause damage to the wheel 3, and there is no need to open the inflation mechanism to inflate the inflatable member 2, thereby saving energy.

[0049] The process of obtaining the pressure value of the pressure sensor 5, comparing the pressure value and the threshold value, and controlling the opening of the inflation mechanism according to the comparison result is stored in the above-mentioned controller in the form of a computer program. The controller can be an electronic control unit (ECU) of the whole vehicle or a separately provided controller.

[0050] The anti-collision device provided by the embodiment of the present application can protect the wheel 3, the half shaft, and the steering knuckle 4, and can also protect the cyclists who are side-collided with the wheel 3, having a dual protection effect.
