Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a guide ring mounting mechanism, a seat belt system, and a vehicle. Background Technology

[0002] Vehicles have brought convenience to people's travel. While enjoying the convenience brought by vehicles, people are also paying more and more attention to vehicle safety and riding comfort. Seat belts are an indispensable safety device for vehicles. In the event of a collision, emergency braking or other unexpected situations, seat belts will fix the occupants in their seats and reduce injuries caused by factors such as inertia.

[0003] As people's demands for vehicle ride comfort gradually increase, the design of the guide ring in existing technologies tends to ensure the seat belt's position guarantees occupant comfort, avoids pressure on the occupant's neck, and ensures ample seating space. However, this results in the guide ring being too far from the occupant, which can easily lead to seat belt slippage and other problems that affect the effectiveness of occupant protection. Utility Model Content

[0004] In view of this, this application provides a guide ring mounting mechanism and a vehicle to solve the problem in the prior art where the mounting position of the guide ring tends to ensure the comfort of the seat belt for the occupant, but the protection effect for the occupant is not good.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A guide ring mounting mechanism for a vehicle, the guide ring mounting mechanism comprising:

[0007] A first mounting component is used to mount a guide ring and is movably disposed at the installation position of the guide ring mounting mechanism. When the vehicle does not collide, the first mounting component is located in a first position.

[0008] A detection element for detecting whether the vehicle has been involved in a collision;

[0009] A drive mechanism is provided for driving the first mounting member to move backward along the length direction and inward along the width direction when the detection unit detects a collision with the vehicle, so that the first mounting member moves from the first position to the second position.

[0010] Optionally, the guide ring mounting mechanism further includes a second mounting member, which is used to be mounted at the position to be installed, and the first mounting member and the second mounting member are slidably connected in the direction from the first position to the second position.

[0011] Optionally, the second mounting member is a tapered structure, and the width of the second mounting member gradually increases from the front end to the rear end along the length direction.

[0012] Optionally, the first mounting member is a tapered structure, and the width of the first mounting member gradually decreases from the front end to the rear end along the length direction. The surface of the first mounting member used to mount the guide ring is a first surface, and the surface of the second mounting member used to fit and connect with the position to be installed is a second surface. The first surface and the second surface satisfy the parallel condition.

[0013] Optionally, the guide ring mounting mechanism further includes a locking mechanism, which is connected to the second mounting member and is used to lock or unlock the first mounting member;

[0014] In the first position, the locking mechanism locks the first mounting member so that the first mounting member and the second mounting member are relatively fixed;

[0015] In the event of a vehicle collision, the locking mechanism unlocks the first mounting member, allowing the first mounting member to move relative to the second mounting member.

[0016] Optionally, the locking mechanism includes a first locking plate and a second locking plate;

[0017] In the first position, the first locking piece and the second locking piece limit the first mounting member along the direction from the first position to the second position and the opposite direction, so that the first mounting member and the second mounting member are relatively fixed.

[0018] In the event of a vehicle collision, the driving force of the drive mechanism that moves the first mounting member can cause the second locking piece that blocks the first mounting member from moving to the second position to break, thereby allowing the first mounting member to move relative to the second mounting member.

[0019] Optionally, the guide ring mounting mechanism further includes a first limiting member and a second limiting member, wherein the first limiting member is connected to the first mounting member and the second limiting member is connected to the second mounting member;

[0020] At the first position, the first limiting member and the second limiting member are spaced apart;

[0021] In the second position, the second limiting member limits the first limiting member in the direction from the first position to the second position, thereby limiting the first mounting member.

[0022] Optionally, the driving mechanism includes a pyrotechnic power unit, which includes a cylinder, a push rod at least partially movably disposed within the cylinder, and a pyrotechnic gas generator. The pyrotechnic gas generator is disposed at a first end of the cylinder and seals a first opening at the first end of the cylinder. The end of the push rod facing the pyrotechnic gas generator is in sealed contact with the inner wall of the cylinder, so that the cylinder, the push rod, and the pyrotechnic gas generator form a sealed space.

[0023] When the detection element detects a collision with the vehicle, the pyrotechnic gas generator pushes the push rod to move, and the push rod pushes the first mounting member from the first position to the second position.

[0024] A seatbelt system includes a guide ring and a guide ring mounting mechanism as described above, wherein the guide ring is mounted on a first mounting member.

[0025] A vehicle comprising the aforementioned seatbelt system.

[0026] When the guide ring mounting mechanism of this embodiment is installed in a vehicle, during normal use, the first mounting member is located in the first position, and the position of the guide ring ensures the comfort of the occupant wearing the seat belt. In the event of a collision, the first mounting member moves the guide ring relative to the seat to the rear and inward side, moving it to the second position, thereby improving the restraint effect of the seat belt on the occupant and enhancing the protection effect. Therefore, applying the guide ring mounting mechanism of this embodiment to a vehicle can solve the problem in the prior art where the installation position of the guide ring tends to ensure the comfort of the seat belt for the occupant, but the protection effect for the occupant is not good.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] like Figures 1-7 As shown, this application embodiment provides a guide ring mounting mechanism for a vehicle. This guide ring mounting mechanism 100 includes a first mounting member 110, a detection element, and a drive mechanism.

[0048] The first mounting member 110 is used to install the guide ring 200 and is movably disposed at the installation position on the vehicle, such as the vehicle body 300. The movement of the first mounting member 110 relative to the installation position can drive the guide ring 200 to move relative to the installation position.

[0049] The detection element is used to detect whether a vehicle collision has occurred, and the drive mechanism is used to drive the first mounting member 110 to move. When the vehicle has not been involved in a collision, that is, during normal use, the first mounting member 110 is located in the first position. In the first position, the position of the guide ring 200 can ensure the comfort of the occupant when wearing the seat belt 500. When the detection element detects that the vehicle has been involved in a collision, the drive mechanism can drive the first mounting member 110 to move backward along the length direction X and inward along the width direction Y, so that the first mounting member 110 moves from the first position to the second position.

[0050] Optionally, the detection element can be an airbag controller. The airbag controller can be electrically connected to the drive mechanism via wiring harness 154. When the airbag controller determines that a collision has occurred, the airbag controller sends a current pulse to the drive mechanism. After receiving the current, the drive mechanism starts and drives the first mounting component 110 to move.

[0051] Optionally, the detection element can also be a collision sensor, and the guide ring mounting mechanism can also include a controller (which can be the vehicle's central processing unit or a dedicated controller for the guide ring mounting mechanism 100). The drive mechanism and the collision sensor are both connected to the controller (the connection can be made via electrical wiring harness, wireless connection, Bluetooth connection, etc.). After the collision sensor detects a collision, it transmits a signal to the controller, which then controls the drive mechanism to start.

[0052] Optionally, the power output end of the drive mechanism can be connected to the first mounting part 110 by means of screw connection, bonding, snap-fit, etc., so that the drive mechanism can drive the first mounting part 110 to move after starting; or, the power output end of the drive mechanism can also be opposite to or abut against the first mounting part 110, so that the drive mechanism can push the first mounting part 110 to move after starting.

[0053] It should be noted that when the guide ring mounting mechanism 100 is installed on the vehicle, the length direction X of the guide ring mounting mechanism 100 is consistent with the length direction X of the vehicle, that is, the direction from the front to the rear of the vehicle, and the width direction Y of the guide ring mounting mechanism 100 is consistent with the width direction of the vehicle, that is, the direction between the two opposite doors of the vehicle.

[0054] The further back the guide ring 200 is relative to the seat 400 and the closer it is to the center of the seat 400, the better the restraint effect on the occupant. When a vehicle collision occurs, the drive mechanism drives the first mounting member 110 to move the guide ring 200 backward along the length direction X and inward along the Y direction to the second position. During the process of the first mounting member 110 moving from the first position to the second position, the guide ring 200 moves backward and inward relative to the seat 400, so that the guide ring 200 is closer to the back of the seat 400 in the length direction X and closer to the seat 400 in the width direction Y, so that the seat belt 500 can better ensure the safety of the occupant.

[0055] When the guide ring mounting mechanism 100 of this embodiment is installed in a vehicle, during normal use, the first mounting member 110 is located in the first position, and the position of the guide ring 200 ensures the comfort of the occupant wearing the seat belt 500. In the event of a collision, the first mounting member 110 moves the guide ring 200 relative to the seat 400 to the rear and inward side to the second position, improving the restraint effect of the seat belt 500 on the occupant and enhancing the protection effect. Therefore, applying the guide ring mounting mechanism 100 of this embodiment to a vehicle can solve the problem in the prior art where the installation position of the guide ring tends to ensure the comfort of the seat belt for the occupant, but the protection effect for the occupant is poor.

[0056] There are several ways to make the first mounting component 110 movably positioned at the installation location.

[0057] In one alternative embodiment, a groove can be machined at the installation position, the groove extending in the direction from the first position to the second position, and the first mounting member 110 can be provided with a slider that extends into the groove and is slidably connected to the groove in the direction from the first position to the second position, thereby movably setting the first mounting member 110 at the installation position.

[0058] In this structure, the depth of the groove (the depth direction is consistent with the width direction Y) opened at the installation position along the length direction X from the front end to the rear end can decrease.

[0059] In this embodiment, the guide ring mounting mechanism 100 may further include a second mounting member 120. The second mounting member 120 can be fixedly installed at the installation position by means of bolt connection, welding, or other methods. The first mounting member 110 and the second mounting member 120 are slidably connected in the direction from the first position to the second position. In this case, the second mounting member 120 achieves a movable connection between the first mounting member 110 and the installation position, eliminating the need to create a groove at the installation position and reducing damage to the vehicle.

[0060] Specifically, the first mounting component 110 may be provided with a first slide rail 111. The first slide rail 111 can be fixed to the first mounting component 110 by means of screw connection, riveting, welding, etc., or it can be integrally formed with the first mounting component 110. The second mounting component 120 may be provided with a second slide rail 121. The second slide rail 121 can be fixed to the second mounting component 120 by means of screw connection, riveting, welding, etc., or it can be integrally formed with the second mounting component 120. The first slide rail 111 may be formed with a groove extending in the direction from the first position to the second position. The second slide rail 121 may be provided with a hook extending in the direction from the first position to the second position. The hook extends into the groove, and the groove and the hook slide in cooperation in the direction from the first position to the second position, and limit cooperation in a plane perpendicular to the direction from the first position to the second position, so that the first slide rail 111 and the second slide rail 121 slide in cooperation, thereby making the first mounting component 110 and the second mounting component 120 slide connected in the direction from the first position to the second position.

[0061] The second mounting member 120 can be a conical structure. The width of the second mounting member 120 can gradually increase from the front end to the rear end along the length direction X, so that when the first mounting member 110 slides relative to the second mounting member 120, the first mounting member 110 can move backward along the length direction X and inward along the width direction Y.

[0062] The second mounting member 120 may also have a sliding groove. The depth of the sliding groove (the depth direction is consistent with the width direction Y) can decrease from the front end to the rear end along the length direction X, so that when the first mounting member 110 slides relative to the second mounting member 120, the first mounting member 110 can move backward along the length direction X and move inward along the width direction Y.

[0063] In a further technical solution, the first mounting member 110 can also be a tapered structure. Along the length direction X from the front end to the rear end, the width of the first mounting member 110 can gradually decrease. The surface of the first mounting member 110 used to mount the guide ring 200 is the first surface 112, and the surface of the second mounting member 120 used to fit and connect with the position to be installed is the second surface 122. The first surface 112 and the second surface 122 satisfy the parallel condition.

[0064] It should be noted that the first surface 112 and the second surface 122 satisfying the parallel condition means that the first surface 112 and the second surface 122 are parallel or approximately parallel. For example, the included angle between the first surface 112 and the second surface 122 can be within 10°.

[0065] The position for installing the guide ring 200 in a vehicle that does not use the guide ring mounting mechanism 100 in this application embodiment (i.e., the prior art) is referred to as the original installation position. The guide ring mounting mechanism 100 in this application embodiment is installed in the original installation position (i.e., the above-mentioned position to be installed is the same as the original installation position). The second surface 122 is attached to the original installation position, so that the second surface 122 is parallel to the original installation position. The first surface 112 and the second surface 122 satisfy the parallel condition (i.e., parallel or approximately parallel), so that the first surface 112 and the original installation position satisfy the parallel condition.

[0066] In this case, keeping the first surface 112 parallel to the original installation position can reduce or even eliminate the change in the angle of the guide ring 200 relative to the original design angle caused by the addition of the guide ring installation mechanism 100. This improves the consistency between the path of the seat belt 500 after passing through the guide ring 200 and the original design, avoids increased friction or abnormal wear of the seat belt 500 caused by the change in the angle of the guide ring 200, ensures the normal operation of the seat belt system, and alleviates the problem of changes in the position and angle of the shoulder strap of the seat belt 500 caused by the change in the angle of the guide ring 200, which may affect wearing comfort and even the effective protection of the occupant in an emergency.

[0067] The guide ring mounting mechanism 100 may further include a locking mechanism connected to the second mounting member 120 for locking or unlocking the first mounting member 110. In a first position, the locking mechanism locks the first mounting member 110 so that the first mounting member 110 and the second mounting member 120 are relatively fixed, ensuring the positional stability of the guide ring 200 when no vehicle collision occurs. In the event of a vehicle collision, the locking mechanism unlocks the first mounting member 110 so that the first mounting member 110 can move relative to the second mounting member 120 to a second position, thereby enabling the seat belt 500 to better protect the safety of the occupants.

[0068] There are various structures for the locking mechanism. In one optional embodiment, the locking mechanism can be a telescopic member such as an electric telescopic rod. The telescopic member is communicatively connected to a controller such as an airbag controller. The telescopic member can be installed on the vehicle body 300 or the second mounting member 120. Along the direction from the first position to the second position, the telescopic member can be located downstream of the first mounting member 110 and abut against the first mounting member 110. In the first position, the telescopic member is in an extended state, so that the telescopic member limits the first mounting member 110 in the direction from the first position to the second position, preventing the first mounting member 110 from moving to the second position. In the event of a vehicle collision, the controller such as the airbag controller controls the telescopic member to retract, so that the telescopic member separates from the first mounting member 110 and no longer blocks the movement of the first mounting member 110, so that the first mounting member 110 can move to the second position under the drive of the drive mechanism.

[0069] Furthermore, there can be two telescopic components. Along the direction from the first position to the second position, the two telescopic components can be located on both sides of the first mounting component 110. In the first position, the two telescopic components are extended and clamp the first mounting component 110 inside to prevent the first mounting component 110 from moving and to improve the positional stability of the first mounting component 110 and the guide ring 200.

[0070] In this embodiment, the locking mechanism may include a first locking piece 131 and a second locking piece 132. The first locking piece 131 and the second locking piece 132 may be connected to the second slide rail 121 or the second mounting member 120 by welding. In the first position, the first locking piece 131 and the second locking piece 132 limit the first mounting member 110 in the direction from the first position to the second position and in the opposite direction, so that the first mounting member 110 and the second mounting member 120 are relatively fixed in the first position. In the event of a vehicle collision, the driving force of the drive mechanism that drives the first mounting member 110 to move can cause the second locking piece 132 that blocks the first mounting member 110 from moving to the second position to break, so that the first mounting member 110 can move relative to the second mounting member 120 to the second position.

[0071] In this case, the locking mechanism is formed by a mechanical structure, which is reliable and can avoid the problem of electronic components going out of control when the vehicle is involved in a collision.

[0072] Specifically, along the direction from the first position to the second position, the first locking piece 131 and the second locking piece 132 can be located on both sides of the first slide rail 111 respectively, clamping the first slide rail 111 inside, thereby limiting the first mounting member 110 by limiting the first slide rail 111 in the direction from the first position to the second position and in the opposite direction.

[0073] It should be noted that the first locking piece 131 and the second locking piece 132 lock the first mounting piece 110 through the structure of the material itself. When the vehicle collides, the drive mechanism applies a driving force to the first mounting piece 110, and the first mounting piece 110 applies pressure to the second locking piece 132. When the force on the second locking piece 132 exceeds the fracture limit of its material itself, it fractures and fails.

[0074] In a further technical solution, the guide ring mounting mechanism 100 also includes a first limiting member 141 and a second limiting member 142. The first limiting member 141 is connected to the first mounting member 110, and the second limiting member 142 is mounted on the second mounting member 120. In the first position, the first limiting member 141 and the second limiting member 142 are spaced apart. In the second position, the second limiting member 142 limits the first limiting member 141 in the direction from the first position to the second position, thereby limiting the first mounting member 110, restricting the stroke of the first mounting member 110, and preventing the first mounting member 110 from continuing to move after moving to the second position. This ensures the positional stability of the first mounting member 110 and the guide ring 200 in the second position, and improves the protection effect of the seat belt 500 on the occupants when a vehicle collision occurs.

[0075] Specifically, the first limiting member 141 can be connected to the first slide rail 111, thereby connecting to the first mounting member 110. The first limiting member 141 and the first slide rail 111 can be stamped and bent. The second limiting member 142 can be connected to the second slide rail 121, thereby mounting to the second mounting member 120. The second limiting member 142 and the second slide rail 121 can be stamped and bent.

[0076] The geometric dimensions of the first limiting member 141 and the second limiting member 142 can be larger than those of the first locking piece 131 and the second locking piece 132, and the tensile strength of the materials of the first limiting member 141 and the second limiting member 142 is higher than that of the first locking piece 131 and the second locking piece 132. For example, the first locking piece 131 and the second locking piece 132 can be made of plastic, and the first limiting member 141 and the second limiting member 142 can be made of steel. In this way, the force that would break the second locking piece 132 cannot break the first limiting member 141 and the second limiting member 142. The force applied by the drive mechanism to the first mounting member 110 (i.e., the force that pushes the push rod 152) can be within the range that would break the first locking piece 131 and the second locking piece 132, but would not break the first limiting member 141 and the second limiting member 142.

[0077] In the above text, the drive mechanism is used to drive the first mounting part 110 to the second position when the vehicle collides. The drive mechanism can be installed at the position to be installed by means of bolt connection, welding or other methods.

[0078] There are various types of drive mechanisms available, including linear motors, pneumatic cylinders, and hydraulic cylinders.

[0079] In this embodiment, the drive mechanism may include a pyrotechnic power unit 150. The pyrotechnic power unit 150 includes a cylinder 151, a push rod 152 at least partially movably disposed within the cylinder 151, and a pyrotechnic gas generator 153. The pyrotechnic gas generator 153 is disposed at the first end of the cylinder 151 and seals the first opening at the first end of the cylinder 151. The pyrotechnic gas generator 153 may be welded to the first end and communicate with the airbag controller via a wiring harness 154. The end of the push rod 152 facing the pyrotechnic gas generator 153 may be sealed to the inner wall of the cylinder 151 via a sealing gasket, so that the cylinder 151, the pyrotechnic gas generator 153, and the push rod 152 form a sealed space. The pyrotechnic gas generator 153 has an exhaust port facing the sealed space.

[0080] When no collision occurs, the pyrotechnic power unit 150 is not powered and is in an untriggered state. When the detection element detects a collision, the pyrotechnic gas generator 153 is ignited to produce gas (i.e., when the airbag controller determines that a collision has occurred, the airbag controller controls the pyrotechnic gas generator 153 to be ignited to produce gas). The gas is discharged into the sealed space and expands within the sealed space. The pressure generated can push the push rod 152 to move. The movement of the push rod 152 can push the first mounting member 110 from the first position to the second position.

[0081] The pyrotechnic power unit 150 has a fast response speed. In the event of a vehicle collision, the pyrotechnic power unit 150 can quickly start and push the first mounting component 110 to the second position, thereby enabling the seat belt 500 to better protect the safety of the occupants. In addition, the pyrotechnic power unit 150 has a simple and compact structure, small size and light weight, which contributes to the lightweight design of the vehicle.

[0082] In other alternative embodiments, the drive mechanism may be an electromechanical spring-type power unit, including a cylinder 151, a push rod 152 at least partially movably disposed within the cylinder 151, a spring, and an electromagnet. The electromagnet may include an electromagnetic coil and a permanent magnet. The electromagnetic coil may be disposed at the first end of the cylinder 151 and communicate with the airbag controller via a wiring harness 154. The permanent magnet may be located within the cylinder 151 and connected to the electromagnetic coil via the spring. When no collision occurs, the electromagnetic coil and the permanent magnet attract each other, the spring is compressed, and the permanent magnet separates from or abuts against the push rod 152. In the event of a collision, the electromagnetic coil and the permanent magnet repel each other, the spring recovers its deformation, and the permanent magnet pushes the push rod 152 to move. The push rod 152 pushes the first mounting member 110 to move, so that the first mounting member 110 moves to a second position.

[0083] like Figure 8 and Figure 9 Based on the aforementioned guide ring mounting mechanism 100, this application embodiment also provides a seat belt system. This seat belt system includes a guide ring 200 and the aforementioned guide ring mounting mechanism 100. The guide ring 200 can be mounted to the first mounting member 110 by bolt connection, interference fit, welding, or other methods. Since this seat belt system has the aforementioned guide ring mounting mechanism 100, the beneficial effects brought by the guide ring mounting mechanism 100 to the seat belt system are described above and will not be repeated here.

[0084] The seat belt system also includes a seat belt 500, a retractor 600, a locking tongue 700, and a lower anchor point 800. The seat belt 500 passes through the guide ring 200 to change the direction in which the seat belt 500 is pulled out of the retractor 600 and to provide a point of application for the seat belt 500. The connection relationships and functions between the guide ring 200, the seat belt 500, the retractor 600, and the locking tongue 700 of the seat belt system are existing technologies and will not be described in detail here.

[0085] Based on the aforementioned seatbelt system, this application also provides a vehicle, which can be a new energy vehicle, a fuel vehicle, or a hybrid vehicle, and includes the aforementioned seatbelt system. Since this vehicle has the aforementioned seatbelt system, the beneficial effects brought by the seatbelt system are described above and will not be repeated here.

[0086] The guide ring mounting mechanism 100 can be installed on the B-pillar or at the mounting position of the guide ring in a conventional vehicle.

[0087] The vehicle in this embodiment can simultaneously take into account both the wearing comfort and safety attributes of the seat belt 500, solving the problem of poor seat belt occupant protection in commercial vehicles, large MPVs, SUVs and other models where the B-pillar is far from the occupants and the passenger compartment has too much space in the width direction Y.
