Description

Technical Field

[0001] This utility model belongs to the field of seat belt technology, and particularly relates to a buckle mechanism, seat belt buckle, seat belt assembly and vehicle. Background Technology

[0002] As a key protective component for occupants in vehicles, seat belts, taking vehicles as an example, currently have buckles mostly located on the side of the seat. Their installation is rigid; occupants need to pull the buckle to engage with the buckle to fasten the seat belt. When occupants get out of the vehicle, they need to manually press the unlock button on the buckle to unfasten the seat belt.

[0003] The awkward installation of seatbelt buckles on the side of the seat makes it seem lacking in technology and intelligence, and it also makes fastening or unfastening the seatbelt inconvenient. Especially with the continuous development of new energy vehicles, the level of vehicle intelligence is constantly improving, and many high-end models have made their doors, seats, lights and steering wheels intelligent (such as having welcome and / or farewell functions).

[0004] To further improve the intelligence level of vehicles, it is important to realize intelligent processing of seat belt buckles. Utility Model Content

[0010] Furthermore, the electrically controlled telescopic drive includes an electrically controlled linear drive, and the end of the buckle facing away from the slot opening is connected to the drive end of the electrically controlled linear drive.

[0011] The advantages of the above-mentioned further technical solutions are that they are simple in structure and easy to operate.

[0012] Furthermore, the electrically controlled telescopic drive also includes a connecting strip, one end of which is connected to the drive end of the electrically controlled linear drive, and the other end of which is connected to the end of the buckle facing away from the slot opening.

[0013] The beneficial effects of the above-mentioned further technical solution are as follows: the electronically controlled linear drive component is hidden under the side of the seat, which improves the aesthetics of the cab, while the connecting strip provides room for movement of the buckle within the space.

[0014] Furthermore, the connecting strip is a steel strand or a steel bar.

[0015] The beneficial effects of the above-mentioned further technical solution are that it has good toughness, can lift the buckle upward, and has a certain bending characteristic under the action of external force.

[0016] Furthermore, the electrically controlled telescopic drive also includes a housing, one end of which is provided with an opening. The electrically controlled linear drive is disposed inside the housing, and one end of the connecting strip extends into the housing through the opening and is connected to the drive end of the electrically controlled linear drive.

[0017] The beneficial effect of the above-mentioned further technical solution is that it makes the entire electronically controlled telescopic drive component more aesthetically pleasing.

[0018] Furthermore, the housing is a strip-shaped housing, the opening is located at one end of the side wall of the housing, and a steering component is provided inside the housing near the opening, and the connecting strip is bent around the steering component.

[0019] The beneficial effect of the above-mentioned further technical solution is that the housing can be installed on the lower side of the seat in the left-right direction or in the front-back direction, while the end of the connecting strip located outside the housing remains vertically upward on the side of the seat.

[0020] Furthermore, the opening is flared outwards.

The gear is coaxially fixedly disposed at the drive end of the motor, and the gear meshes with the drive rack. The motor rotates forward or in reverse to drive the drive rack to move the connecting strip relative to the housing.

[0027] The beneficial effect of the above-mentioned further technical solution is that the motor drives the gear to rotate forward or backward, which in turn drives the drive rack to move back and forth, and drives the connecting bar to move relative to the housing and adjusts the extension of the connecting bar relative to the housing, and finally causes the buckle to extend from the side of the seat or retract to the reset position.

[0028] Furthermore, the electrically controlled telescopic drive also includes a braking component, which is disposed within the housing. When the buckle is in the extended or reset state, the braking component is used to brake the drive rack.

[0029] The beneficial effect of the above-mentioned further technical solution is that when the buckle is in the extended or reset state, the brake can brake the drive rack to ensure that the drive rack can withstand the huge impact force of the driver and passengers when the vehicle is involved in an accident.

[0030] Furthermore, the braking component includes an electromagnetic drive and a brake rack. The electromagnetic drive is disposed within the housing, and the brake rack is disposed at the drive end of the electromagnetic drive.

[0048] Example 1 like Figures 1-4As shown, this embodiment provides a buckle mechanism 10, including a buckle 1 and an electrically controlled telescopic drive 2. The buckle 1 has a slot 11 and an unlocking button 12, and the buckle 1 contains a lock cylinder 13 and a sensor 14. The sensor 14 is used to sense whether the buckle body 20 is inserted into the slot 11. The end of the buckle 1 facing away from the slot 11 is connected to the drive end of the electrically controlled telescopic drive 2. The electrically controlled telescopic drive 2 drives the buckle 1 to extend or retract to its reset position. This enables the buckle mechanism 10 to have intelligent functions for welcoming and sending off guests. Specifically, when the driver or passenger needs to insert or uninsert the buckle body 20 into the buckle 1, the electrically controlled telescopic drive 2 drives the buckle 1 to move upwards until it extends onto the seat.

[0049] in, Figure 1 and Figure 2 The dashed line "A" in the middle represents the seat surface.

[0050] In this embodiment, both the buckle base 1 and the buckle body 20 are existing mature products. The arrangement and structure of the slot 11, unlock button 12, lock cylinder 13, and sensor 14 of the buckle base 1 are also existing technologies. In the prior art, one end of the buckle body 20 has a tongue 210 with a hole. In use, the tongue 210 is inserted into the buckle base 1 through the slot 11 and locked with the tongue 210 by the lock cylinder 13. At this time, the tongue 210 is inserted into the buckle base 1 and will trigger the sensor 14 to generate a sensing signal. When the unlock button 12 is pressed manually, the lock cylinder 13 can be driven to release the lock from the tongue 210 and push the buckle body 20 upward. Then, the unlock button 12 can be released, and the buckle body 20 can be easily pulled out from the buckle base 1.

[0051] like Figure 3 and Figure 4 As shown, in the prior art, the process of fastening a seatbelt involves the buckle 20 being inserted into the buckle seat 1 (at which point the sensor 14 senses that the buckle 20 is inserted into the buckle seat 1), while the process of unfastening the seatbelt involves the buckle 20 being released from the buckle seat 1 (at which point the sensor 14 senses that the buckle 20 is pulled out of the buckle seat 1). In this embodiment, the sensor 14 can be a pressure sensor, a magnetic induction switch, or a contact resistance switch, etc., all of which are prior art and will not be described in detail here.

[0052] The operable state of the electrically controlled telescopic drive component 2 described in this embodiment can be set as needed. Here, only two examples are given to briefly introduce the setting of the operating logic: Logic 1: If the vehicle is unlocked and the driver's door is opened (assuming that the driver and passengers need to get in the vehicle), the electric telescopic drive 2 can drive the buckle 1 to move upward along the side of the seat to extend, which makes it easier for the driver and passengers to fasten their seat belts. After the driver and passengers have fastened their seat belts, the electric telescopic drive 2 drives the buckle 1 to move the buckle body 20 downward to reset (this extension-retraction process is regarded as the welcoming stage). When the vehicle is turned off or an emergency occurs, the electronically controlled telescopic drive 2 drives the buckle seat 1 to move the buckle body 20 upward along the side of the seat to extend, which makes it easier for the driver and passengers to unbuckle the seat belt. After the driver and passengers unbuckle the seat belt and the vehicle is locked (it can be assumed that the driver and passengers have gotten out of the vehicle), the electronically controlled telescopic drive 2 drives the buckle seat 1 downward to reset (this extension-retraction process is regarded as the farewell stage).

[0053] Logic 2: The buckle 1 remains in the extended state under the drive of the electronically controlled telescopic drive 2. Only when the seat belt is fastened will the electronically controlled telescopic drive 2 drive the buckle 1 to retract to the reset position (the process from unlocking the vehicle and opening the driver's door to the buckle 1 retracting to the reset position is considered the welcoming stage). When the vehicle is turned off or an emergency occurs, the electronically controlled telescopic drive 2 will drive the buckle 1 to move upward along the side of the seat to extend, so that the driver and passengers can unfasten the seat belt (the process from the buckle 1 extending to the seat belt unfastening and the vehicle locking is considered the departing stage). The difference between Logic 1 and Logic 2 is that when the vehicle is locked, the latch body in Logic 1 is in a reset state, while the latch body in Logic 2 remains in an extended state (specifically, in Logic 1, the latch seat needs to complete two steps of extension and retraction in both the welcoming and farewell stages, while in Logic 2, only the retraction action needs to be completed in the welcoming stage, and only the extension action needs to be completed in the farewell stage).

[0054] In this embodiment, new energy vehicles typically have an intelligent power-on function, meaning that the vehicle automatically starts when the driver's door is unlocked and opened.

[0055] In this embodiment, an emergency situation may be a vehicle collision or thermal runaway of the power battery. For new energy vehicles, collision sensors are installed to monitor whether a collision has occurred (and determine whether the airbags need to be deployed accordingly), and the power battery's BMS system monitors whether thermal runaway of the power battery has occurred in real time.

[0056] The contents of Logic 1 and Logic 2 mentioned above are not the focus of this embodiment. They are only used to illustrate the modes of the buckle mechanism 10 provided in this embodiment in the welcoming and farewell functions from the perspective of examples.

[0057] like Figure 1 and Figure 2 As shown, the electrically controlled telescopic drive component 2 in this embodiment includes an electrically controlled linear drive component 21. The end of the buckle 1 facing away from the slot 11 is connected to the drive end of the electrically controlled linear drive component 21. Its structure is simple and easy to operate. In this embodiment, the electrically controlled linear drive component 21 is a lead screw linear drive component, a telescopic electric cylinder, or an electromagnetic push rod. Its structure is simple, its control is convenient, and it also has a built-in braking function. In this embodiment, the electrically controlled linear drive component 21 can be directly and vertically installed on the side of the seat.

[0058] like Figure 5 As shown, in this embodiment, both the electronically controlled linear drive component 21 and the sensor component 14 can be electrically connected to the vehicle's ECU (engine control unit) via cables. Alternatively, in this embodiment, the latching mechanism 10 can be matched with a lower-level controller 3 (the lower-level controller can be an ARM series microcontroller). Both the electronically controlled linear drive component 21 and the sensor component 14 can be electrically connected to the lower-level controller 3, which in turn is electrically connected to the vehicle's ECU (engine control unit).

[0059] In this embodiment, the lower controller 3 can be installed in the driver's cab and located in the center console or under any seat (if the driver's seat, passenger seat and rear seats in the vehicle all use the buckle mechanism provided in this embodiment, multiple buckle mechanisms can share one lower controller 3).

[0060] Example 2 Same as Example 1, except that, as Figure 6 As shown, in this embodiment, the buckle 1 is provided with a light-emitting lamp 15 at the slot end corresponding to the slot 11. This allows the light-emitting lamp 15 on the buckle 1 to serve as part of the vehicle's ambient lighting, which not only enhances the aesthetics and technological feel of the vehicle's interior but also makes it easier for drivers and passengers to quickly identify the position of the buckle 1, thereby improving the convenience of fastening and unfastening seat belts.

[0061] In this embodiment, the light lamp 15 can emit different colors of light according to different vehicle states. The light emission logic of the light lamp 15 can be set according to specific needs. For example, the light lamp 15 can emit green light during the welcoming stage and yellow light during the farewell stage; or during the welcoming and farewell stages, the light lamp 15 emits green light when the seat belt is fastened and red light when the seat belt is unfastened.

[0062] In this embodiment, the improvement of the buckle 1 compared with the prior art is only that a light-emitting lamp 15 is added to the slot of its slot 11 (of course, the light-emitting lamp 15 can also be embedded in the unlock button 12, that is, the unlock button has a light-emitting function). The material used at the position where the light-emitting lamp 15 is embedded on the buckle 1 is light-transmitting plastic.

[0063] like Figure 7 As shown, in this embodiment, the light lamp 15 can be electrically connected to the vehicle's ECU (engine control unit) via a cable, or the light lamp 15 can be electrically connected to the lower controller 3.

[0064] Example 3 Same as Embodiment 1 or Embodiment 2, except that, as Figure 8 and Figure 9 As shown, in this embodiment, the electrically controlled telescopic drive component 2 further includes a connecting strip 22. One end of the connecting strip 22 is connected to the drive end of the electrically controlled linear drive component 21, and the other end of the connecting strip 22 is connected to the end of the buckle 1 opposite to the slot 11. This allows the electrically controlled linear drive component 21 to be hidden under the side of the seat, improving the aesthetics of the cab, while the connecting strip 22 provides the buckle 1 with room for movement within the space.

[0065] in, Figure 8 and Figure 9 The dashed line "A" in the middle represents the seat surface.

[0066] In this embodiment, the connecting strip 22 is a steel strand or steel bar, which has good toughness and can lift the buckle 1 upwards, while also having certain bending characteristics under external force.

[0067] In this embodiment, whether the buckle 1 is in the extended state or the reset state, the electrically controlled linear drive component 21 is hidden under the side of the seat, which makes it aesthetically pleasing.

[0068] Example 4 Same as Example 3, except that, as Figures 10-12 As shown, the electrically controlled telescopic drive component 2 also includes a housing 23. One end of the housing 23 has an opening 231. The electrically controlled linear drive component 21 is disposed within the housing 23. One end of the connecting strip 22 extends into the housing 23 through the opening 231 and is connected to the drive end of the electrically controlled linear drive component 21. The electrically controlled linear drive component 21 drives the connecting strip 22 to move relative to the housing 23, thereby adjusting the extension amount of the connecting strip 22 relative to the housing 23. This improves the overall aesthetics of the electrically controlled telescopic drive component 2.

[0069] in, Figures 10-12 The dashed line "A" in the middle represents the seat surface.

[0070] In this embodiment, the housing 23 is a strip-shaped housing. The opening 231 is located at one end of the side wall of the housing 23. A steering member 232 is provided inside the housing 23 near the opening 231. The connecting strip 22 is bent around the steering member 232. This allows the housing 23 to be installed on the lower side of the seat in a left-right or front-back direction, while the end of the connecting strip 22 located outside the housing 23 remains vertically upward on the side of the seat.

[0071] In this embodiment, the electrically controlled linear drive 21 is disposed inside the housing 23 along the length direction of the housing 23, that is, the reciprocating movement direction of the drive end of the electrically controlled linear drive 21 is consistent with the length direction of the housing 23.

[0072] In this embodiment, the opening 231 is flared, which gives the opening 231 a certain straightening function for the connecting strip 22.

[0073] In this embodiment, the steering component 232 is a guide wheel (such as...). Figure 10 and Figure 11 (as shown) or guide block (such as) Figure 12 As shown in the figure, its structure is simple and the connecting strip 22 can be bent to turn.

[0074] like Figure 12 As shown, in this embodiment, when the steering component 232 is a guide block, the contact point between the steering component 232 and the guide bar is arc-shaped (the arc center angle can be greater than 90°), which can better guide the connecting bar 22 and reduce the coefficient of friction between the steering component 232 and the connecting bar 22.

[0075] Example 5 Same as Example 4, except that, as Figures 13-17 As shown, the electrically controlled linear drive 21 in this embodiment includes a motor 211, a gear 212, and a drive rack 213. The drive rack 213 is slidably disposed within the housing 23. One end of the connecting strip 22 located within the housing 23 is connected to the drive rack 213. The motor 211 is installed within the housing 23. The gear 212 is coaxially fixedly disposed at the drive end of the motor 211, and the gear 212 meshes with the drive rack 213. The motor 211 rotates forward or reverse to drive the drive rack 213, thereby moving the connecting strip 22 relative to the housing 23. This causes the motor 211 to drive the gear 212 to rotate forward or reverse, which in turn drives the drive rack 213 to reciprocate, and moves the connecting strip 22 relative to the housing, adjusting the extension amount of the connecting strip 22 relative to the housing, and ultimately causing the buckle 1 to extend from the side of the seat or retract to its reset position.

[0076] In this embodiment, the length direction of the drive rack 213 is consistent with the length direction of the housing 23, and the drive rack 213 slides back and forth along the length direction of the housing 23 within the housing 23.

[0077] In this embodiment, the motor 211 can be a decelerated braking motor, which makes the up-and-down movement speed of the buckle 1 relatively slow, and the buckle 1 has a certain braking function when it is in the extended state or the reset state.

[0078] like Figure 13 , Figure 14 , Figure 16 and Figure 17 In this embodiment, the electrically controlled telescopic drive component 2 further includes a brake component 24, which is disposed within the housing 23. When the latch 1 is in the extended or reset state, the brake component 24 is used to brake the drive rack 213. This ensures that when the latch 1 is in the extended or reset state, the brake component 24 can brake the drive rack 213, thus ensuring that the drive rack 213 can withstand the enormous impact force of the occupants during the forward tilting moment in the event of a vehicle accident.

[0079] Specifically, such as Figure 16 and Figure 17 As shown, the braking component 24 in this embodiment includes an electromagnetic drive component 241 and a braking rack 242. The electromagnetic drive component 241 is disposed inside the housing 23, and the braking rack 242 is disposed at the driving end of the electromagnetic drive component 241. When the latch 1 is in the extended state or the reset state, the electromagnetic drive component 241 drives the braking rack 242 to mesh with the driving rack 213 to brake the driving rack 213. It has a simple structure and good braking effect.

[0080] In this embodiment, when the electromagnetic drive unit 241 is energized, it drives the brake rack 242 to mesh with the drive rack 213 to brake the drive rack 213. When the electromagnetic drive unit 241 is de-energized, it drives the brake rack to return to its original position to separate from the drive rack 213 (i.e., release the brake). In this embodiment, the electromagnetic drive unit 241 can be an electromagnetic push rod.

[0081] In this embodiment, the length of the brake rack 242 is less than the length of the drive rack 213.

[0082] Specifically, such as Figure 18 As shown, in this embodiment, the motor 211 and the electromagnetic drive unit 241 are directly electrically connected to the ECU or electrically connected to the lower controller 3.

[0083] In this embodiment, the corresponding ends of the drive rack 213 and the connecting strip 22 can be pressed together or integrally formed.

[0084] Example 6 like Figure 19 and Figure 20 As shown, this embodiment provides a seatbelt buckle, including a buckle body 20 and a buckle seat mechanism 10 as described in Embodiments 1, 2, 3, 4, or 5. This allows the buckle seat 1 of the seatbelt buckle to be in an extended or reset state under the drive of the electrically controlled telescopic drive 2. In the extended state, the buckle body 20 can be easily inserted into or released from the buckle seat 1. In this embodiment, one end of the buckle body 20 has a tongue 210 with a hole, which can be inserted into the slot 11.

[0085] The buckle 20 described in this embodiment is existing technology and will not be elaborated upon here.

[0086] Example 7 This embodiment provides a seat belt assembly, including the seat belt buckle as described in Embodiment 6. This gives the seat belt assembly a high degree of intelligence, especially providing welcoming and farewell functions.

[0087] The seat belt assembly described in this embodiment also includes components such as the seat belt body, seat belt retractor, seat belt pretensioner, and seat belt tension limiter.
