[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0049] In existing technologies, seatbelt dispensers utilize gear transmission. Therefore, the drive mechanism must be integrated with the transmission gears, and the drive mechanism and housing cannot be installed separately. This results in the drive mechanism needing to be installed close to the seat headrest. Furthermore, the drive mechanism generates noise during operation, resulting in a poor passenger experience. Therefore, a new technical solution is proposed to address or improve the aforementioned technical issues.

[0050] In the first aspect of the present application, a driving device is provided. Figures 1 to 5 .

[0051] In some embodiments, the drive device comprises:

[0052] The transmission mechanism 1 includes a flexible transmission member 11 and a guide mechanism 12 for transmitting power. The flexible transmission member 11 is installed on the guide mechanism 12 and is configured to change the transmission direction to adapt to the guide change of the guide mechanism 12; and an adapter 2, which is connected to the flexible transmission member 11 and is configured to be connected to the safety belt and move under the drive of the flexible transmission member 11 to deliver or retract the safety belt.

[0053] It should be noted that the drive device includes a transmission mechanism 1, which includes a bendable flexible transmission member 11 and a guide mechanism 12. The transmission structure 1 includes a flexible transmission member and a guide mechanism. The flexible transmission member can be arranged in various shapes through the guide mechanism (better applicability). The guide mechanism can transmit power and change the direction of power transmission. The flexible transmission member transmits power to the adapter, which in turn transmits power to the safety belt, so that the adapter can deliver or recycle the installation belt. The flexible transmission member 11 can flexibly change the transmission path and the length of the transmission path through the arrangement of the guide mechanism 12. The implementer can flexibly set the guide mechanism 12 as needed. In addition, the flexible transmission member 11 forms a preset transmission trajectory around the guide mechanism 12. It can be understood that when the transmission distance is certain, the flexible transmission member has a simpler structure and is better arranged than the rigid transmission member. In addition, the flexible transmission member can avoid the meshing noise of the meshing structures of each stage during the multi-stage transmission of the rigid transmission member, that is, it helps to reduce the transmission noise. The adapter 2 is fixedly connected to the flexible transmission member 11. When the flexible transmission member 11 is driven to move by power, the adapter 2 can slide between a first position (such as a retracted state) and a second position (such as a delivery state).

[0054] The drive device reduces the space limitation of the flexible transmission member 11 through flexible transmission, is applicable to complex installation environments, makes the setting position of the drive source more flexible, and in practice, can be set away from the user to further reduce noise. For example, in a safety belt delivery device, the adapter 2 can be an arc-shaped delivery arm, which realizes the delivery or retraction of the safety belt by the expansion and contraction of the pull rope 111. At the same time, the power component (motor) of the drive device can be installed away from the adapter 2, so that when used in the safety belt delivery device, the power component is installed separately from the housing 6 on which the delivery arm is installed, and the power component forms a certain installation distance with the delivery arm of the delivery device, thereby reducing the noise transmitted to the member.

[0055] In some embodiments, the flexible transmission member 11 is a pull rope 111 or a transmission belt 112, so that it can be arranged around the guide mechanism and the drive structure can be arranged away from the adapter.

[0056] In one case, see Figure 1 and Figure 2 The flexible transmission member 11 is a pull rope 111, the end of which is fixed to the adapter 2 through the connecting block 51. The pull rope 111 changes direction through the guide mechanism 12, for example, passing through the first rotating wheel 121 and the second rotating wheel 122 to form a multi-segment transmission path.

[0057] Alternatively, see Figure 4 and Figure 5The flexible transmission member 11 is a transmission belt 112, which includes various types such as synchronous belts, flat belts, and V-belts. The flexibility of the transmission belt 112 makes it suitable for power transmission over long distances or on curved paths. The surface of the synchronous belt has teeth. It can be understood that the surface of the rotating wheel that cooperates with the synchronous belt should be provided with matching teeth to facilitate power transmission. In addition, when installing the pull rope 111 (or transmission belt), the pull rope (or transmission belt) should be properly tightened to facilitate power transmission. In particular, flat belts and V-belts that transmit power through friction should have sufficient pressure on the surface of the rotating wheel.

[0058] In some embodiments, the guide mechanism 12 includes a first rotating wheel 121; the first rotating wheel 121 is configured to drive the flexible transmission member 11 to move. It should be noted that the first rotating wheel 121 is an active component in the transmission path, which usually needs to be connected to the shaft 7 of the driving mechanism 3 (such as a motor) to obtain the power of the driving mechanism 3 and transmit the power to the flexible transmission member 11. Figure 1 In the embodiment, the driving mechanism 3 drives the first rotating wheel 121 to rotate through the shaft 7, driving the pull rope 111 or the transmission belt 112 to move. Usually, the surface of the first rotating wheel 121 is provided with a groove or a tooth structure, which fits tightly with the flexible transmission member 11 to ensure efficient power transmission.

[0059] In some embodiments, see Figures 2 to 5 , the guide mechanism 12 also includes a second wheel 122, the flexible transmission member 11 is a ring structure, the flexible transmission member 11 is sleeved on the first wheel 121 and the second wheel 122, and the portion of the flexible transmission member 11 between the first wheel 121 and the second wheel 122 is in a tensioned state. The second wheel 122 is configured to change the transmission direction of the flexible transmission member 11, and is arranged at one end away from the first wheel 121. It should be noted that the second wheel 122 serves as a driven component, and is used to change the direction of the flexible transmission member 11. By cooperating with the first wheel 121 and the second wheel 122, the power transmission efficiency can be improved. The portion of the flexible transmission member 11 between the first wheel 121 and the second wheel 122 is in a tensioned state to facilitate power transmission. For example, in Figure 1 and Figure 2 In the embodiment, the pull rope 111 is led out from the first rotating wheel 121, passes through the second rotating wheel 122, and is connected to the adapter 2, and then passes through the guide unit 123 to form a circular path. The installation position of the first rotating wheel 121 and the second rotating wheel 122 can be adjusted to ensure that the flexible transmission member 11 is always in a tensioned state.

[0060] In some embodiments, see Figure 2 、 Figure 4 and Figure 5, the guide mechanism 12 includes a plurality of guide units 123, and the plurality of guide units 123 are arranged between the first rotating wheel 121 and the second rotating wheel 122, and each of the guide units 123 is used to overlap with the flexible transmission member 11, and at least one of the plurality of guide units 123 is used to constrain the extension direction of the portion of the flexible transmission member 11 located between the first rotating wheel 121 and the second rotating wheel 122. Wherein, the guide unit 123 is a guide wheel and / or a guide block, and the guide wheel and / or the guide block are used to meet the spatial arrangement requirements of the flexible transmission member 11. The guide wheel can be used for reversing the flexible transmission member 11 and also for transmitting power, and its power loss is relatively small. The guide block is mainly used to limit the position of the flexible transmission member 11. For example, Figure 2 In the rope transmission structure, the guide unit 123 includes a guide block and guide wheels, which together form a Z-shaped transmission path. Adjusting the position of the guide unit 123 allows for adaptability to different spatial layout requirements. Furthermore, a U-shaped groove within the guide block limits the lateral movement of the flexible transmission member 11, preventing it from jumping out of the guide block. The rollers are made of nylon or polyurethane to reduce wear on the flexible transmission member 11.

[0061] In some embodiments, see Figure 2 、 Figure 4 and Figure 5 The portion of the flexible transmission member 11 between the first rotating wheel 121 and the second rotating wheel 122 extends in a curved shape. To accommodate complex spatial layouts or long-distance power transmission, the flexible transmission member 11 extends between the first rotating wheel 121 and the second rotating wheel 122, enabling power transmission between the first rotating wheel 121 and the second rotating wheel 122.

[0062] In some embodiments, see Figure 1 and Figure 2 The drive device also includes a connecting block 51, through which the flexible transmission member 11 is connected to the adapter 2. It should be noted that the connecting block 51 serves as a fixed node between the flexible transmission member 11 and the adapter 2. The pull rope 111 / transmission belt 112 passes through the connecting block 51 to facilitate a fixed connection with the adapter 2. The transmission belt 112 is connected to the connecting block 51 via bolts or clips. The connecting block 51 can be fixed to the adapter 2 via bolts, clips, etc. This structure enhances transmission stability and prevents it from falling off.

[0063] In some embodiments, see Figure 3In the case where the flexible transmission member 11 is a pull rope 111, both ends of the pull rope 111 are fixedly mounted on the connecting block 51 to form a ring structure. In this way, the pull rope 111 can be wound around the guide mechanism 12 and can transmit power to the connecting block 51. The shape of the connecting block 51 is adapted to the installation of the adapter 2 and the pull rope 111.

[0064] In some embodiments, see Figure 3 The connecting block 51 is provided with a mounting groove 52, and both ends of the pull rope 111 are fixedly mounted in the mounting groove 52. By installing the pull rope 111 in the mounting groove 52, the mounting groove 52 can limit the moving position of the pull rope 111 and confine the pull rope 111 in the groove.

[0065] Furthermore, the mounting groove 52 is X-shaped, with the ends of the pull cord 111 cross-mounted within the X-shaped mounting groove 52. The X-shaped mounting groove 52 allows the ends of the pull cord 111 to be cross-mounted. The ends of the pull cord 111 are mounted within the mounting groove 52, and the pull cord 111 cross-mounted within the mounting groove 52. This X-shaped mounting groove 52 limits the movement of the pull cord 111, confining it within the groove and preventing it from interfering with the movement of the adapter 2. For example, the ends of the pull cord 111 are inserted through the two openings of the mounting groove 52, cross-mounted, and secured with a compression bolt.

[0066] In some embodiments, see Figure 4 and Figure 5 In the case where the flexible transmission member 11 is a transmission belt 112, the connecting block 51 is fixedly mounted on the outer surface of the transmission belt 112, so that the connecting block 51 can be firmly connected to the transmission belt 112. The transmission member can be installed by screws or adhesive.

[0067] In some embodiments, see Figure 2 、 Figure 4 and Figure 5 , further comprising a slide rail 41, the adapter 2 being slidably mounted on the slide rail 41, the adapter 2 being configured to slide along the slide rail 41 under the drive of the flexible transmission member 11, so that the adapter 2 is driven and the shape of the mounted slide rail 41 moves. The setting of the slide rail 41 enables the adapter 2 to move along the path of the slide rail 41, specifically, the adapter 2 slides along the slide rail 41 between the first position and the second position, thereby achieving the delivery or recovery of the safety belt. The slide rail 41 can be a curved structure with a certain curvature, or it can be a straight structure. As in Figure 1In the rope-type delivery device, the slide rail 41 is an arc-shaped structure that mates with the adapter 2. At least one of the contact surfaces of the slide rail 41 and the adapter 2 is provided with a lubricant. The lubricant applied to the contact surface between the slide rail 41 and the adapter 2 can be applied to the slide rail 41 and / or the adapter 2. The lubricant applied to the surface of the slide rail 41 reduces frictional resistance and ensures smooth movement of the adapter 2. The choice of lubricant should be determined based on the specific application scenario, load, speed, temperature, and environmental conditions. Lubricants include grease, oil, solid lubricants, and others.

[0068] In some embodiments, see Figure 1 and Figure 2 、 Figure 4 and Figure 5 The drive device further includes a drive mechanism 3, which is used to drive the guide mechanism 12 to drive the flexible transmission member 11 to move, thereby realizing the drive structure 3 driving the flexible transmission member 11. It should be noted that the drive mechanism 3 includes a drive shaft 7 and a first rotating wheel 121 directly or indirectly provided on the shaft 7. The flexible transmission member 11 is mounted on the first rotating wheel 121, and the flexible transmission member 11 should not slide relative to the first rotating wheel 121. By driving the first rotating wheel 121 by the drive device to drive the flexible transmission member 11 to move, the flexible transmission member 11 can be controllably moved between the first position and the second position.

[0069] Furthermore, the drive mechanism 3 is a motor, serving as a power source for the driven structure. Motors offer advantages such as high efficiency, compact size, and high reliability. Drive mechanism 3 is preferably a low-noise motor, with its output shaft 7 connected to the first rotating wheel 121. The motor's speed and torque can be adjusted by a controller to meet power requirements under different operating conditions. For example, in a seatbelt dispenser, the motor operates in intermittent mode, activating only when a seatbelt is needed for delivery or retraction, thereby reducing energy consumption.

[0070] In some embodiments, the adapter 2 has a working end connected to the safety belt, and the drive mechanism 3 is arranged away from the working end of the adapter 2. It should be noted that the drive mechanism 3 is arranged away from the working end of the adapter 2 in order to reduce the impact of the noise of the drive mechanism 3 when it is working on the passengers. For example, the drive mechanism 3 is arranged separately from the adapter 2, see Figure 2 By extending the transmission mechanism 1, power is transmitted to the adapter 2. This design reduces the impact of noise from the operating drive mechanism 3 on passengers. When used in a seatbelt dispenser, the drive mechanism 3 can be positioned away from the delivery arm (adapter 2), thereby reducing noise. Furthermore, the remote placement of the drive mechanism 3 optimizes space utilization.

[0071] In some embodiments, see Figure 2 、 Figure 4 and Figure 5, the adapter 2 is a delivery arm for delivering or retrieving the seat belt. It should be noted that the delivery arm (adapter 2) of the seat belt deliverer is driven by a driving device and moves along the slide rail 41. When the passenger takes his seat, the driving mechanism 3 is started, and the flexible transmission member 11 drives the delivery arm from the retracted position to the delivery position, pushing the seat belt into the passenger's hand range. This design helps to optimize the user experience and reduces the inconvenience of passengers bending over to find the seat belt. It should be understood that the delivery arm has a clamping device for installing the seat belt. An elastic clamping device is provided at the end of the delivery arm to ensure that the seat belt is automatically released after delivery.

[0072] In some embodiments, see Figure 2 、 Figure 4 and Figure 5 The delivery arm is curved. It should be noted that the curvature of the curved delivery arm typically matches the ergonomic design, ensuring a smooth and natural delivery trajectory for the safety belt. The curved structure of the slide rail 41 is integrally formed with the delivery arm to reduce vibration and noise during movement. Typically, the delivery arm has a curvature radius of 300mm-500mm, which is suitable for the reach of an adult's arm.

[0073] In a second aspect of the present application, a safety belt deliverer is provided, comprising the aforementioned driving device. The safety belt deliverer comprises all the technical features of the aforementioned driving device and therefore also has all the technical effects of the driving device.

[0074] In some embodiments, the seat belt dispenser includes a housing 6, and at least a portion of the drive device is disposed within the housing 6. It should be noted that the adapter 2 and the slide rail 41 are at least partially disposed within the housing 6. It is understood that the adapter 2 can be at least partially retracted into the housing 6, or can be mostly extended outside the housing 6. The housing 6 is used to protect the components installed therein. In order to reduce the impact of noise on the occupants or eliminate the impact of noise, the drive mechanism 3 of the drive device is installed outside the housing 6, and the drive mechanism 3 is at a certain distance from the adapter 2, so that the drive mechanism 3 is at a sufficient distance from the position of the human ear to reduce the impact of noise.

[0075] The third aspect of the present application provides a vehicle comprising the aforementioned drive device and / or the aforementioned seatbelt dispenser. Since the vehicle possesses all the technical features of the drive device and / or the seatbelt dispenser, it also possesses all the technical effects thereof. The vehicle may be a sedan, bus, or flying car, and the seatbelt dispenser may be mounted on the side or top of the seat. Typically, the dispenser is integrated into the seat headrest or inside the door to save space. It may also be linked to the safety system via the vehicle's CAN bus to synchronize the delivery action with the seatbelt locking.

[0076] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0077] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0078] The embodiments, implementation methods and related technical features of the present application can be combined and replaced with each other without conflict.

[0079] The above are merely preferred embodiments of the present application and do not constitute any form of limitation to the present application. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application are still within the scope of the technical solution of the present application.
