Abstract
Description
Technical Field
[0001] This application relates to the field of clock spring technology, and in particular to a clock spring stop pin, a clock spring, a steering wheel assembly, and a vehicle. Background Technology
[0002] A clock spring is a special electrical connection device with a spiral structure. It is installed under the vehicle's steering wheel and can maintain a stable connection between components such as airbags and multi-function buttons and the vehicle's electrical system when the steering wheel is turned at multiple angles, thereby ensuring the normal operation of each component.
[0003] Clock springs typically consist of a mating body and a stop pin. The stop pin secures the rotating components inside the body, preventing accidental rotation during transport or installation. Once the clock spring is installed in the vehicle, with the steering wheel and body in the center position, the stop pin is pulled out, releasing the rotating components and allowing them to rotate normally with the steering wheel.
[0004] However, the locking pins currently on the market require a large locking force to be overcome when pulled out, making them inconvenient for operators to remove. Utility Model Content
[0005] In view of this, this application provides a clock spring stop pin, a clock spring, a steering wheel assembly, and a vehicle, to at least solve the problem in the prior art that the clock spring stop pin requires a large locking force to be overcome when pulled out, making it inconvenient for operators to pull it out.
[0006] To achieve the above objectives, the technical solution of this application is implemented as follows:
[0007] This application provides a clock spring stop pin, including: a handle, a clamping member, and a pin; the clamping member is connected to one side of the handle along a first direction, and the clamping member is provided with a locking part, which is adapted to cooperate with the clock spring body for locking; the pin is arranged along the first direction and is connected to the clamping member; the pin and the locking part are spaced apart in a second direction; wherein, the second direction intersects the first direction.
[0008] Optionally, the locking part is a groove or through hole provided along the thickness direction of the clamping member.
[0009] Optionally, the clamping member is further provided with a hollow hole, the hollow hole and the locking part are located on the same side of the clamping member, and the hollow hole is located on the side closer to the pin.
[0010] Optionally, the dimension of the handle along the second direction is larger than the dimension of the clamping member along the second direction, and the clamping member is connected to the middle of the handle.
[0011] Optionally, the two sides of the handle that are opposite each other along the second direction are curved surfaces.
[0012] Optionally, the handle has a reinforcing rib on at least one surface along its thickness direction, the reinforcing rib being arranged along the second direction, and the surface of the reinforcing rib being arc-shaped.
[0013] Optionally, the clamping member has a clamping groove on the side opposite to the handle, and the wall thickness of the groove does not exceed 3mm; and / or, the thickness of the handle does not exceed 7mm.
[0014] Optionally, the end of the pin is also connected to the handle.
[0015] Optionally, the handle, the clamping member, and the pin are integrated as a single unit.
[0016] This application also provides a clock spring, including a clock spring body and a clock spring stop pin as described in any of the preceding claims. The clock spring body includes a connector and a locking hole disposed on the periphery of the connector. The clamping member is connected to the connector, and the pin is inserted into the locking hole.
[0017] This application also provides a steering wheel assembly including the aforementioned clock spring.
[0018] This application also provides a vehicle including the aforementioned clock spring or the aforementioned steering wheel assembly.
[0019] Compared to existing technologies, the clock spring stop pin, clock spring, steering wheel assembly, and vehicle described in this application have the following advantages:
[0020] The process of removing the clock spring stop pin in this application is as follows: Turning the handle causes the clamping component to rotate slightly, disengaging the locking part on the clamping component from the clock spring body, thereby pulling the pin out of the clock spring body. During the rotation of the clamping component by the handle, the pin, inserted into the locking hole on the clock spring body, acts as a pivot during rotation. Simultaneously, the pin and the locking part are spaced apart in a second direction, forming a rotational force arm. Under the action of this force arm, the operator can easily disengage the locking part from the locking structure by turning the handle with minimal force, similar to turning a key. This allows the pin to be easily pulled out of the locking hole. Compared to existing technologies, this removal method effectively reduces the locking force required to remove the clock spring stop pin, allowing the operator to remove it with minimal force by turning the handle, greatly facilitating the removal operation.
[0021] The clock spring, steering wheel assembly, and vehicle described in this application have the same or similar advantages as the prior art and the aforementioned clock spring stop pin, which will not be elaborated here. Attached Figure Description

[0034] The following detailed description of a clock spring stop pin, clock spring, steering wheel assembly, and vehicle provided in this application is illustrated by specific embodiments.
[0035] Figure 1 A schematic diagram of a clock spring stop pin 1 is shown. Figure 2 An enlarged schematic diagram of the clock spring stop pin 1, handle 11, and clamping member 12 is shown below. Figure 1 and Figure 2 As shown, this application embodiment provides a clock spring stop pin 1, which includes: a handle 11, a clamping member 12, and a pin 13; the clamping member 12 is connected to one side of the handle 11 along the first direction Z, and the clamping member 12 is provided with a locking part 121, which is adapted to cooperate with the clock spring body 2 for locking; the pin 13 is arranged along the first direction Z and is connected to the clamping member 12; the pin 13 and the locking part 121 are spaced apart in the second direction X; wherein, the second direction X intersects the first direction Z.
[0036] In this embodiment, the clock spring stop pin 1 is a component of the clock spring. The clock spring mainly includes the clock spring body 2 and the clock spring stop pin 1. The clock spring body 2 includes a lower housing 22, an upper housing 21, a spiral wire harness, a guide and support structure, etc. The clock spring stop pin 1 is fixed to the upper housing 21. Before the clock spring is installed on the vehicle, the spiral wire harness inside the upper housing 21 is in the middle position and is locked and fixed by the clock spring stop pin 1 to prevent accidental rotation. After the clock spring is installed on the vehicle, the clock spring stop pin 1 is pulled out to release the spiral wire harness and restore the function of the spiral wire harness rotating with the steering wheel.
[0037] The clock spring stop pin 1 includes a handle 11, a clamping member 12, and a pin 13. The handle 11 is used for the operator to grip when the clock spring stop pin 1 is pulled out. In this embodiment, the handle 11 is designed as a thin handle structure, which is more convenient for the operator's fingers to grip, and it is not easy to slip during the gripping process, so as not to cause injury to the operator's hands. The clamping member 12 is connected to one side of the handle 11 along the first direction Z. The clamping member 12 and the handle 11 can be connected by any method such as assembly connection, adhesive connection, laser welding, etc., and this embodiment does not limit this.
[0038] The clamping member 12 is provided with a locking part 121, which is adapted to cooperate with the clock spring body 2 for locking. Specifically, the upper housing 21 of the clock spring body 2 is usually provided with a connector 211, which is usually also provided with a locking structure. The locking part 121 is adapted to the locking structure. After the locking part 121 and the locking structure are connected, the clamping member 12 and the connector 211 can be locked and fixed. When the clock spring stop pin 1 is pulled out from the clock spring body 2, the stop pin needs to be rotated first to loosen the locking part 121 from the locking structure on the connector 211, and then the clock spring stop pin 1 can be pulled out.
[0039] The pin 13 is positioned along the first direction Z, and the pin 13 is relatively long along the first direction Z. The pin 13 is connected to the clamping member 12. The pin 13 and the clamping member 12 can be connected by any method such as assembly connection, adhesive connection, laser welding, etc., and this embodiment does not limit this. The upper housing 21 of the clock spring body 2 is also provided with a locking hole 212. The end of the pin 13 facing away from the handle 11 is inserted into the locking hole 212, thereby locking and fixing the spiral wire harness inside the upper housing 21 to prevent the spiral wire harness from rotating accidentally. When the clock spring stop pin 1 is pulled out from the clock spring body 2, the pin 13 needs to be pulled out from the locking hole 212. Therefore, the process of pulling the clock spring stop pin 1 out of the clock spring body 2 is as follows: Rotate the handle 11 of the clock spring stop pin 1. The handle 11 causes the clamping member 12 to rotate appropriately, causing the locking part 121 on the clamping member 12 to disengage from the locking structure on the clock spring body 2. Then, the pin 13 is pulled out from the locking hole 212 on the clock spring body 2, thus completing the removal of the clock spring stop pin 1. Figure 2 The clock spring stop pin 1 shown can be pulled out by turning the handle 11 counterclockwise.
[0040] The pin 13 and the locking part 121 are spaced apart in the second direction X, wherein the second direction X intersects the first direction Z. Figure 1 and Figure 2The diagram illustrates a pairwise perpendicular arrangement of the first direction Z and the second direction X. Perpendicularity includes not only absolute perpendicularity but also approximate perpendicularity, such as when the angle between the first direction Z and the second direction X is 89° to 91°. Thus, during the rotation of the clamping member 12 driven by the handle 11, the pin 13, inserted into the locking hole 212 on the clock spring body 2, acts as a pivot during rotation. Simultaneously, the pin 13 and the locking part 121 are spaced apart in the second direction X, forming a rotational force arm. Under the action of this force arm, the operator can easily disengage the locking part 121 from the locking structure by rotating the handle 11 with minimal force, similar to turning a key. This allows the pin 13 to be pulled out of the locking hole 212. Compared with existing technologies, this extraction method effectively reduces the locking force that the clock spring stop pin 1 needs to overcome when it is pulled out, allowing the operator to pull out the clock spring stop pin 1 with a smaller force by turning the handle 11, which greatly facilitates the operator's extraction operation.
[0041] Optionally, refer to Figure 2 As shown, in some embodiments of this application, the locking part 121 is a groove or through hole provided along the thickness direction of the clamping member 12. It can be understood that the groove does not penetrate the clamping member 12 along the thickness direction of the clamping member 12, while the through hole penetrates the clamping member 12. The locking structure on the connector 211 of the clock spring body 2 is a protrusion adapted to the groove or through hole. The protrusion is embedded in the groove or through hole to achieve locking and fixing of the clamping member 12 and the connector 211.
[0042] Optionally, refer to Figure 2 As shown, in some embodiments of this application, the clamping member 12 is also provided with a hollow hole 122. The hollow hole 122 and the locking part 121 are located on the same side of the clamping member 12, and the hollow hole 122 is located on the side close to the pin 13. Figure 2 In the clock spring stop pin 1 shown, the hollow hole 122 is a strip-shaped hole arranged along the first direction Z, and the strip-shaped hole is located beside the pin 13. In other embodiments, the hollow hole 122 can also be a hole of other shapes and structures, such as a circular hole, an elliptical hole, a polygonal hole, etc., which can all be located beside the pin 13. The hollow hole 122 helps to reduce the structural strength of the clamping member 12, and facilitates the deformation of the clamping member 12 during the rotation of the clamping member 12 driven by the handle 11. This facilitates the release of the locking part 121 on the clamping member 12 from the locking structure on the clock spring body 2, and makes it easier to pull out the clock spring stop pin 1.
[0043] Optionally, refer to Figure 1 and Figure 2As shown, in some embodiments of this application, the dimension of the handle 11 along the second direction X is larger than the dimension of the clamping member 12 along the second direction X, and the clamping member 12 is connected to the middle of the handle 11. Specifically, the clamping member 12 is mainly used to clamp onto the connector 211 of the clock spring body 2 to achieve the pre-installation of the clock spring stop pin 1. Therefore, the dimension of the clamping member 12 is set according to the dimension of the connector 211, and is usually set to be slightly smaller than the dimension of the connector 211. The handle 11 is mainly used by the operator to grip and perform rotation and pull-out operations. That is, the handle 11 needs to withstand the rotational force and pull-out force applied by the operator. In order to avoid excessive deformation or damage to the handle 11, the dimension of the handle 11 along the second direction X is set to be larger to improve the strength and rigidity of the handle 11. At the same time, it is easier for the operator to grip the handle 11, and it is less likely to slip during the rotation or pull-out operation, which is more conducive to the smooth pull-out of the clock spring stop pin 1. Meanwhile, the clamping member 12 is connected to the middle of the handle 11 along the second direction X, which makes it easier for the operator to rotate or pull out the clamping member 12 with uniform force, thus making it easier for the locking part 121 on the clamping member 12 to be released.
[0044] Optionally, refer to Figure 1 and Figure 2 As shown in some embodiments of this application, the two sides of the handle 11 that are opposite each other along the second direction X are arc surfaces. For example, the handle 11 can be in the shape of a round handle, an elliptical handle, etc. The two sides of the handle 11 that are opposite each other along the second direction X are arc surfaces, and the center of curvature of the arc surface is located on the side closer to the center of the handle 11. This arrangement can reduce the sharp parts on the handle 11. When the clock spring stop pin 1 is transported or assembled, it helps to prevent the handle 11 from snagging on the operator's clothing, gloves, etc., thereby helping to prevent the clock spring stop pin 1 from accidentally falling off the clock spring body 2.
[0045] Optionally, refer to Figure 1 and Figure 2 As shown in some embodiments of this application, at least one surface of the handle 11 along its thickness direction is provided with a reinforcing rib 111. The reinforcing rib 111 is arranged along a second direction X, and the surface of the reinforcing rib 111 is arc-shaped. Specifically, the reinforcing rib 111 can enhance the strength and rigidity of the handle 11, preventing excessive deformation or damage to the handle 11 during rotation or pull-out operations. Furthermore, the arc-shaped surface of the reinforcing rib 111 indicates that it is a rib structure provided on the handle 11, protruding from the surface of the handle 11. The arc-shaped surface of the reinforcing rib 111 prevents the addition of sharp parts to the handle 11, thus reducing the likelihood of the reinforcing rib 111 snagging on the operator's clothing, gloves, etc., during transportation or assembly of the clock spring stop pin 1, and preventing accidental detachment of the clock spring stop pin 1.
[0046] Furthermore, there can be multiple reinforcing ribs 111, with multiple reinforcing ribs 111 spaced apart along the first direction Z, and multiple reinforcing ribs 111 can be evenly distributed on the handle 11. This arrangement can further increase the strength and rigidity of the handle 11 and prevent injection molding shrinkage marks from occurring on the handle 11 during the production process.
[0047] Optionally, in some embodiments of this application, the clamping member 12 has a clamping groove 120 on the side opposite to the handle 11. The clamping groove 120 clamps onto the connector 211 of the clock spring body 2, thereby connecting the clock spring stop pin 1 to the clock spring body 2. It should be noted that the clamping member 12 is clamped onto the connector 211 through the clamping groove 120 to achieve pre-fixation between the clamping member 12 and the connector 211. After the locking part 121 on the clamping member 12 engages with the locking structure on the connector 211 to lock, the clamping member 12 and the connector 211 are locked and fixed, which can prevent the clamping member 12 from coming off the connector 211.
[0048] The wall thickness of the groove 120 does not exceed 3mm. Specifically, the thicker the wall of the groove 120, the stronger the ability of the clamping member 12 to resist rotational deformation during the rotation of the handle 11; the thinner the wall of the groove 120, the weaker the ability of the clamping member 12 to resist rotational deformation during the rotation of the handle 11. Therefore, the wall thickness of the groove 120 is set to not exceed 3mm. For example, the wall thickness of the groove 120 can be set to 1mm, 1.5mm, 2mm, 2.5mm, etc. This ensures that the clamping member 12 has good deformation ability and can rotate appropriately with the handle 11 during the rotation of the handle 11, thereby ensuring that the locking part 121 on the groove wall can be smoothly released from the locking structure on the connector 211. Of course, the wall thickness of the groove 120 should not be too thin. If the wall thickness of the groove 120 is too thin, its strength and rigidity will be low, and it will be impossible to effectively fix the clock spring stop pin 1 to the clock spring body 2. At the same time, it will be easy to damage the clamping part 12 during rotation.
[0049] In addition, in some embodiments of this application, the opening of the clamping groove 120 on the clamping member 12 is approximately 1.5mm to 2mm in the direction of the groove wall thickness. For example, the opening size of the clamping groove 120 can be set to 1.8mm. Within this size range, the mating requirements of most of the connectors 211 on the clock spring body 2 can be met.
[0050] In addition, in some embodiments of this application, the thickness of the handle 11 is approximately 4mm to 7mm. For example, the thickness of the handle 11 can be set to 5mm. Under this thickness condition, it is convenient for the operator to hold the handle 11, and the handle 11 can be guaranteed to have good strength and rigidity.
[0051] Optionally, in some embodiments of this application, the end of the pin 13 is also connected to the handle 11. Specifically, the end of the pin 13 extends along the first direction Z to connect with the handle 11. The pin 13 and the handle 11 can be connected by any method such as assembly connection, adhesive connection, laser welding, etc., and this embodiment does not limit this. Thus, in this embodiment, the pin 13 is connected to both the handle 11 and the clamping member 12, which helps to improve the connection reliability of the pin 13, reduces the possibility of breakage when the pin 13 is pulled out of the locking hole 212, and facilitates the smooth removal of the clock spring stop pin 1.
[0052] Optionally, in some embodiments of this application, the handle 11, the clamping member 12, and the pin 13 are integral parts. For example, the handle 11, the clamping member 12, and the pin 13 can be integrally injection molded from high-strength engineering plastic. The integrally injection molded clock spring stop pin 1 can be installed without additional steps, which helps to reduce production steps. At the same time, the structure has high strength and is not easy to break, which helps to extend the service life of the stop pin.
[0053] Figure 3 A schematic diagram of a clock spring is shown. Figure 4 A cross-sectional view of a clock spring is shown, with reference to... Figure 3 and Figure 4 As shown, this application embodiment also provides a clock spring, including a clock spring body 2 and a clock spring stop pin 1 from any of the preceding embodiments. The clock spring body 2 includes a connector 211 and a locking hole 212 disposed on the periphery of the connector 211. A clamping member 12 is connected to the connector 211, and a pin 13 is inserted into the locking hole 212. The clock spring body 2 includes a lower housing 22, an upper housing 21, a spiral wiring harness, a guide and support structure, etc. The lower housing 22 serves as the fixed end of the clock spring body 2 and is fixed to the steering column of the vehicle for connecting vehicle body wiring harnesses, such as airbag control wiring harnesses and horn control wiring harnesses. The upper housing 21 serves as the rotating end of the clock spring body 2 and is fixed below the vehicle steering wheel, rotating synchronously with the steering wheel for connecting components such as airbags and multi-function buttons. The spiral wiring harness is made of a multilayer flexible printed circuit board (PCB) or a strip copper foil wire harness, which is coiled into a spiral shape and disposed in the upper housing 21 to maintain continuous transmission of electrical signals when the steering wheel rotates. The guiding and supporting structures include slip rings, bearings, etc., to ensure that the upper housing 21 can rotate smoothly and reduce friction and wear.
[0054] The connector 211 is located on the side of the upper housing 21 opposite to the lower housing 22. The connector 211 has a locking hole 212 on its periphery. The clamping member 12 in the clock spring stop pin 1 is clamped on the connector 211 through the clamping groove 120. The pin 13 in the stop pin is inserted into the locking hole 212. Before the clock spring is installed on the vehicle, the spiral wire harness is in the middle position and is locked and fixed by the pin 13 to prevent accidental rotation. After the clock spring is installed on the vehicle, the handle 11 is turned to pull out the clock spring stop pin 1, the pin 13 is disengaged from the locking hole 212, the spiral wire harness is released, and the function of the spiral wire harness rotating with the steering wheel is restored.
[0055] This application also provides a steering wheel assembly, including the clock spring from the aforementioned embodiments. Specifically, the steering wheel assembly further includes a steering wheel frame, an airbag module, multifunction buttons, a steering angle sensor, horn contacts, etc. The steering wheel frame provides the main structural support, ensuring the strength and rigidity of the steering wheel assembly. The airbag module is located in the center of the steering wheel and is connected to the electronic control unit (ECU) of the vehicle's airbags via the clock spring. The multifunction buttons are used to control functions such as audio, cruise control, and voice assistant, and their electrical signals are transmitted through the clock spring. The steering angle sensor is typically integrated into the clock spring or installed independently on the steering column, and the horn contacts transmit the horn trigger signal through the clock spring's circuitry. Thus, the clock spring, as an electrical connection component between the steering wheel assembly and the vehicle body, ensures the smooth transmission of functional signals from the airbag, buttons, horn, etc.
[0056] This application also provides a vehicle including the aforementioned clock spring or steering wheel assembly. Specifically, the clock spring can be used not only in the vehicle's steering wheel assembly but also in the vehicle's steer-by-wire system, rotatable seats, etc. The vehicle can be a pure electric vehicle, a hybrid vehicle, a range-extended vehicle, or a gasoline vehicle, etc.
[0057] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
