Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of vehicles, and particularly relates to a retractor vehicle sensing structure, a retractor device, a seat and a vehicle. BACKGROUND

[0002] The retractor vehicle sensing structure is used for sensing the vibration condition of a vehicle. When the vehicle encounters an emergency situation and generates relatively strong vibration, the retractor vehicle sensing structure locks the reel of the retractor to achieve locking of the safety belt, so as to constrain the passenger on the seat, which plays a relatively important role in driving safety.

[0003] In the prior art, the retractor vehicle sensing structure usually comprises a base, a vehicle sensing ball and a transmission member. The vehicle sensing ball is arranged in the base, and the transmission member is connected to the base and arranged above the vehicle sensing ball. When the vehicle generates relatively strong vibration, the vehicle sensing ball pushes the transmission member to move, and the transmission member is clamped on the reel of the retractor to achieve locking.

[0004] However, in the normal driving process of the vehicle, the vehicle sensing ball will swing in the base with a small amplitude, so that friction is generated between the vehicle sensing ball and the transmission member and the base, and noise is further generated, which affects the NVH (Noise, Vibration, Harshness) performance of the vehicle and reduces the driving experience of the user.

The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally means that the front and rear associated objects are in an "or" relationship.

[0030] In the description of the utility model, it is necessary to understand that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" is the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0031] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0032] Referring to Figs. 1 to 4 , a structure schematic view of a retractor vehicle sensing structure and a reel gear is shown, the retractor vehicle sensing structure specifically can include: base 10, vehicle sensing sphere 20 and transmission part 30;Vehicle sensing sphere 20 is arranged in base 10, and one side of transmission part 30 is rotatably connected to base 10, and transmission part 30 is arranged above vehicle sensing sphere 20;Vehicle sensing sphere 20 is provided with protruding part 21, transmission part 30 is provided with limiting hole 31, and protruding part 21 is arranged in limiting hole 31 to limit the shaking of vehicle sensing sphere 20.

[0033] In the embodiment of the application, when small amplitude shaking occurs during normal driving of the vehicle, the limiting effect of limiting hole 31 on protruding part 21 of vehicle sensing sphere 20 on transmission part 30 limits the shaking of vehicle sensing sphere 20, avoids large amplitude shaking of vehicle sensing sphere 20 in base 10, reduces the friction between vehicle sensing sphere 20 and transmission part 30 and base 10, effectively suppresses noise, so that the vehicle has good NVH (Noise, Vibration, Harshness, noise, vibration, sound roughness) performance, and improves the driving experience of users.

[0034] When the vehicle encounters an emergency situation and generates a stronger vibration, such as sudden braking, collision, and the like, the sensing ball 20 will move away from the base 10 and drive the transmission member 30 to move, so that the transmission member 30 is clamped on the spool gear 40 of the retractor device, the safety belt on the spool gear 40 is locked, and the safety belt is prevented from being pulled out further, thereby protecting the safety of the driver and passenger.

[0035] For example, in the embodiment of the present application, the sensing ball 20 can be made of metal, such as stainless steel or iron, and the like, so that the sensing ball 20 has good sensitivity to the acceleration generated by inertia when the vehicle vibrates. For example, when the acceleration generated by inertia of the vehicle is greater than or equal to 0.45G (where G represents the acceleration of gravity), the sensing ball 20 moves away from the base 10 to drive the transmission member 30 to be clamped on the spool gear 40 of the retractor device to lock the safety belt. For example, when the acceleration generated by inertia of the vehicle is less than or equal to 0.3G, the sensing ball 20 remains in contact with the base 10 and does not drive the transmission member 30 to be clamped on the spool gear 40 to lock the safety belt, so that the driver and passenger can adjust the safety belt in a stationary state or a smooth driving state.

[0036] In the embodiment of the present application, for example, one side of the transmission member 30 can be rotatably connected to the base 10 through a rotating shaft or a pivot, and correspondingly, the base 10 can be provided with a mounting hole, the rotating shaft or the pivot can be arranged in the mounting hole and can rotate in the mounting hole, thereby achieving the rotatable connection between the transmission member 30 and the base 10, which is simple in structure and convenient to operate.

[0037] Alternatively, in some embodiments of the present application, the limiting hole 31 is a through hole, and the protruding part 21 extends out of the through hole. In this way, the through hole has a good limiting effect on the protruding part 21, avoiding that the protruding part 21 may be separated from the limiting hole 31.

[0038] In another optional embodiment of the present application, the limiting hole 31 is a blind hole, and the protruding part 21 is arranged in the blind hole and located below the transmission member 30. That is, the limiting hole 31 can also be a through hole that does not pass through the whole plate of the transmission member 30. In this way, the protruding part 21 of the sensing ball 20 does not need to extend out of the transmission member 30, and the protruding part 21 does not need to occupy the space in the vehicle, thereby improving the space utilization and avoiding that the protruding part 21 of the sensing ball 20 easily interferes with other components in the vehicle during the shaking process.

[0039] Optionally, in the embodiment of the present application, the car sensing ball 20 comprises a spherical base body, at least part of the protruding part 21 is a cylinder, and the axis of the cylinder can extend to the center of the spherical base body. In this way, the axis of the cylinder coincides with the extension of the radius of the spherical base body, so that the protruding part 21 has good consistency with the shaking of the spherical base body, avoiding stress concentration to cause the car sensing ball 20 to be easily damaged and poor stability. Moreover, when manufacturing the protruding part 21, the extension of the radius of the spherical base body can be used as a reference, which has good reliability and is simple to operate.

[0040] For example, in the embodiment of the present application, the diameter of the spherical base body can be any value in the range of 10-15 mm, such as 10 mm, 10.7 mm, 12.7 mm, 14.7 mm or 15 mm, etc., which can be set according to actual needs, and the specific value of the diameter of the spherical base body is not limited in the embodiment of the present application. For example, the mass of the spherical base body can be any value in the range of 8g-15g, such as 8g, 9g, 10g, 13g or 15g, etc., which can be set according to actual needs, and the specific value of the mass of the spherical base body is not limited in the embodiment of the present application.

[0041] In the embodiment of the present application, optionally, the diameter of the limiting hole 31 is any value in the range of 3-5 mm. In this way, it is avoided that the diameter of the limiting hole 31 is too large to cause the protruding part 21 to shake in the limiting hole 31 with a large amplitude, which affects the limiting effect of the car sensing ball 20. It is also avoided that the diameter of the limiting hole 31 is too small to affect the free movement of the car sensing ball 20 in the base 10. For example, the diameter of the limiting hole 31 can be 3 mm, 3.5 mm, 4 mm or 5 mm, etc., and the specific value of the diameter of the limiting hole 31 is not limited in the embodiment of the present application.

[0042] Optionally, in the embodiment of the present application, the base 10 is provided with a groove 11, and the car sensing ball 20 is arranged in the groove 11 and can move in the groove 11. In this way, the groove 11 provides a relatively stable setting space for the car sensing ball 20, avoiding the car sensing ball 20 from easily shaking and separating from the base 10, so that the car sensing structure of the retractor has good reliability and stability.

[0043] In the embodiment of the present application, optionally, the other side of the transmission member 30 is provided with a transmission rod 32, the transmission rod 32 extends away from the car sensing ball 20, and the end of the transmission rod 32 away from the car sensing ball 20 is provided with an engaging part 33 for engaging with the reel gear 40. In this way, when the vehicle encounters an emergency situation and produces a relatively strong vibration, the transmission member 30 moves with the shaking of the car sensing ball 20, so that the engaging part 33 on the transmission rod 32 engages with the ratchet on the reel gear 40 to achieve the locking of the safety belt.

[0044] In an example, in the embodiment of the present application, the transmission member 30 can be a cover plate structure with an arc surface, and the arc surface structure is located at the top of the vehicle sensing ball 20, so that the transmission member 30 has a good fitting effect with the vehicle sensing ball 20. The limiting hole 31 can be arranged in the middle region of the arc surface cover plate structure, so that the transmission member 30 has good structural strength, good stability and reliability.

[0045] In the embodiment of the present application, the transmission member 30 can further include a reinforcing member connected to the arc surface cover plate structure and the transmission rod 32, so as to reinforce the structure of the transmission rod 32. In an example, the reinforcing member can be a reinforcing rib or a reinforcing plate, etc., which can be arranged according to actual needs, and the specific type of the reinforcing member is not limited in the embodiment of the present application.

The vehicle sensing ball is provided with a protruding portion, the transmission member is provided with a limiting hole, and the protruding portion is arranged in the limiting hole to limit the shaking of the vehicle sensing ball. In this way, when the vehicle normally drives and produces a small amplitude of shaking, the limiting hole on the transmission member limits the protruding portion of the vehicle sensing ball, limits the shaking of the vehicle sensing ball, avoids the vehicle sensing ball from producing a large amplitude of shaking in the base, reduces the friction between the vehicle sensing ball and the transmission member and the base, effectively suppresses the noise, makes the vehicle have good NVH performance, and improves the driving experience of the user.

[0049] In an example, in the embodiment of the present application, a plurality of ratchet teeth can be arranged on the retractor gear 40. When the vehicle encounters an emergency and produces a strong vibration, the vehicle sensing ball 20 will move away from the base 10 and drive the transmission member 30 to move, so that the engaging portion 33 of the transmission rod 32 on the transmission member 30 can engage with the ratchet teeth.
