Description

Technical Field

[0001] This utility model relates to the field of car door handle technology, and in particular to a car door handle with a non-independent shaft rotating mechanism and the same. Background Technology

[0002] Currently, car door handles can be opened in two ways: electric and emergency. Electric opening works by the operator pressing a button or touching the door handle to issue an opening command. This command signal is sent to the electronic control unit (ECU), typically the BCM module within the body control module. After verifying the signal's validity, the ECU sends a current signal to the door lock actuator of the target door. The motor within the actuator then starts, driving the bolt to release from the latch, completing the electric opening operation. Emergency opening, also known as mechanical or manual opening, is completely independent of the vehicle's electronic system. It operates the door lock through a purely mechanical structure, aiming to ensure door opening in extreme situations. Typically, the door handle has a mechanical opening mechanism that requires significant external force to open. In an emergency, the operator applies force to the mechanical door handle, causing it to actuate and transmit the force through a pull ring to the door lock assembly. This force directly acts on the mechanical unlocking lever of the door lock assembly, forcibly pulling the bolt away from the latch and releasing the lock.

[0003] Traditional mechanical door handles have a rotating mechanism connected to the handle. When the handle rotates, it drives the rotating mechanism, which in turn moves the pull ring on the mechanism. Traditional rotating mechanisms are usually composed of multiple parts, such as a bracket, a rotating body, a shaft, and an elastic body, which are assembled and axially fixed. This results in a large number of parts, leading to higher costs. Furthermore, the assembly of these parts requires horizontal fixation to prevent axial movement, and the shaft and rotating body need to be axially fixed separately. The processing and installation procedures are complex, affecting processing and assembly efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a rotating mechanism without an independent shaft and a door handle containing the same, in order to solve the technical problem that the rotating mechanisms that cooperate with mechanical door handles in the prior art are generally complicated in terms of processing and installation procedures, which affect the processing and assembly efficiency.

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

[0006] A rotating mechanism without an independent axis, comprising:

[0007] The central shaft is rotatably mounted to the bracket at both ends.

[0008] A rotating body through which the central shaft passes and is fixedly installed relative to the central shaft;

[0009] The guide shaft has one end fixedly installed relative to the rotating body, and the other end slidably installed relative to the handle body;

[0010] The rotating body is also provided with a pull wire hole for connecting one end of the pull wire. An elastic element is fitted on the central shaft. The elastic element is located between the rotating body and the bracket. It is used to provide resistance for the rotating body to rotate around the central shaft and to provide a reset driving force after the rotating body rotates. The rotation of the handle body drives the guide shaft to slide. The sliding of the guide shaft realizes the rotation of the rotating body around the central shaft, and further realizes the pull wire hole to pull the pull wire.

[0011] Furthermore, the rotating body is configured in a triangular shape, with a central shaft installed through one corner of the rotating body, a guide shaft installed at one corner, and a pull wire hole located at the other corner.

[0012] Furthermore, a first limiting groove is provided on the rotating body, which is used to limit one end of the elastic element, and the other end of the elastic element is limited by a second limiting groove on the bracket.

[0013] Furthermore, the rotating body, central shaft, and guide shaft are integrally molded parts, and a through hole is provided inside along the central shaft axis, and a rib is provided at the connection between the hole and the outer edge of the rotating body.

[0014] Furthermore, the outer layer of the ends of the central shaft that contact the bracket is fitted with a wear-resistant layer, and the contact surface of the guide shaft that slides with the handle body is fitted with a wear-resistant layer.

[0015] Furthermore, the elastic element is a torsion spring.

[0016] A car door handle, including the aforementioned non-independent shaft rotating mechanism, comprises a bracket, a handle body, and a handle recess. The handle body is rotatably mounted on the bracket, and the central shaft of the rotating mechanism is rotatably mounted on the bracket. The handle body is provided with an elongated sliding hole for the guide shaft to slide. An elastic element fitted on the central shaft is provided between the end of the central shaft away from the guide shaft and the bracket. The handle recess is fixedly mounted relative to the bracket, and a retaining ring is provided on the central shaft for axially limiting the end of the central shaft away from the guide shaft.

[0017] Furthermore, the bracket is provided with a first limiting part, a second limiting part, a third limiting part and a fourth limiting part. The first limiting part and the second limiting part together form a through hole for the central shaft to pass through, and the third limiting part and the fourth limiting part together form a through hole for the central shaft to pass through.

[0018] Furthermore, the first limiting part and the second limiting part are staggered along the central axis, and the third limiting part and the fourth limiting part are staggered along the central axis.

[0019] Furthermore, the first limiting part and the fourth limiting part are located on one side of the central axis, and the second limiting part and the third limiting part are located on the other side of the central axis. The distance between the first limiting part and the fourth limiting part is greater than the distance between the second limiting part and the third limiting part. The second limiting part is pressed against the side of the rotating body to achieve axial limiting of the central axis in conjunction with the retaining ring.

[0020] Furthermore, the bracket is provided with clearance holes, which are used to provide clearance space for the guide shaft to slide along the handle body.

[0021] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0022] (1). By integrating the central shaft, guide shaft and rotating body into one unit, this utility model avoids the problems of many parts and the need for separate processing and time-consuming assembly process that are common in traditional rotating mechanisms, thus improving processing and assembly efficiency. At the same time, through the sliding cooperation between the guide shaft and the handle body, the rotation of the handle body is converted into the sliding of the guide shaft along it, and then the sliding of the guide shaft is converted into the rotation of the rotating body around the central shaft, thereby realizing the rotation of the pull wire hole, and then realizing the pull wire action, and finally realizing the emergency unlocking operation.

[0023] (2). This utility model limits the elastic torsion spring by setting a first limiting groove and a second limiting groove, so as to facilitate the reset action after emergency unlocking; by setting wear-resistant layers at both ends of the central shaft, it is beneficial to improve the service life of the rotating mechanism and reduce maintenance costs.

[0024] (3). This utility model achieves axial positioning of the central shaft by setting a first limiting part, a second limiting part, a third limiting part and a fourth limiting part on the bracket, combined with a retaining ring, which saves the complex structure caused by axial positioning during the installation of traditional rotating mechanisms, and reduces processing costs and assembly time; by setting the relative positions of the first limiting part, the second limiting part, the third limiting part and the fourth limiting part, it is conducive to quick installation and disassembly of the rotating mechanism, making installation convenient and quick, and improving assembly efficiency.

[0046] To address the limitations of existing technologies, this embodiment provides a technical solution. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0047] This utility model primarily addresses the problem of low processing and assembly efficiency caused by the large number of parts in the rotating mechanism of automobile door handles in existing technologies, and proposes a structural improvement. The specific improvement scheme is as follows:

[0048] Participate in the attached Figure 1 Appendix Figure 13 and attached Figure 14A rotating mechanism without an independent axis includes: a central shaft 104, both ends of which are rotatably mounted to a bracket 200, with a wear-resistant layer fitted on the outer surface of the ends of the central shaft 104 that contact the bracket 200; a rotating body 101 through which the central shaft 104 passes and is fixedly mounted relative to the central shaft 104, wherein the two ends of the central shaft 104 are located on opposite sides of the rotating body 101; a guide shaft 102, one end of which is fixedly mounted relative to the rotating body 101, and the other end of which is slidably mounted relative to a handle body 400, with a wear-resistant layer fitted on the sliding contact surface between the guide shaft 102 and the handle body 400, wherein the wear-resistant layer helps to extend the service life of the guide shaft 102; the rotating body 101 is also provided with a connection for a pull... The cable has a pull hole 106 at one end, which connects to one end of the cable. This cable is a standard component in car door handles used for mechanical emergency unlocking. The other end of the cable connects to the mechanical unlocking mechanism, so pulling the cable will activate the mechanical unlocking action. An elastic element 103, a torsion spring, is mounted on the central shaft 104. This elastic element 103 is located between the rotating body 101 and the bracket 200, providing resistance to the rotation of the rotating body 101 around the central shaft 104 and providing a reset driving force after the rotating body 101 has rotated. In other words, the elastic element 103, i.e., the torsion spring, causes the rotating body 101 to reset after the mechanical unlocking action is completed. The rotation of the handle body 400 drives the guide shaft 102 to slide, which in turn causes the rotating body 101 to rotate around the central shaft 104, further enabling the pull hole 106 to pull the cable. Specifically, the rotating body 101 is triangular in shape, with a central shaft 104 installed through one corner of the rotating body 101, a guide shaft 102 installed at one corner, and a pull hole 106 located at the other corner. A first limiting groove 105 is provided on the rotating body 101, which limits one end of the elastic element 103. The other end of the elastic element 103 is limited by a second limiting groove 205 on the bracket 200. The rotating body 101, central shaft 104, and guide shaft 102 are integrally molded, with a through-hole 107 axially arranged along the central shaft 104. Ribs 108 are provided at the junction of the through-hole and the outer edge of the rotating body 101. It can be understood that integral molding helps reduce processing and assembly steps, improving processing and assembly efficiency. The through-hole 107 and ribs 108 help reduce the weight of the rotating mechanism 100 while ensuring its strength.

[0049] Participate in the attached Figure 2-9A car door handle, including the aforementioned non-independent shaft rotating mechanism 100, comprises a bracket 200, a handle body 400, and a handle recess 300. It can be understood that the bracket 200, handle body 400, and handle recess 300 are conventional components of a car door handle. The handle body 400 is rotatably mounted on the bracket 200. Here, the handle body 400 is rotatably mounted on the bracket 200 via a through-shaft fitted with a large spring. The function of the large spring is to provide resistance to prevent the car lock from being opened due to rotation of the handle body 400 under normal conditions. The operator needs to apply a large external force to rotate the handle body 400 relative to the bracket 200 to achieve emergency opening. Both ends of the central shaft 104 of the rotating mechanism 100 are rotatably mounted on the bracket 200. The handle body 400 has an elongated sliding hole for the guide shaft 102 to slide through. This elongated sliding hole is inclined so that when the handle body 400 rotates, the guide shaft 102 slides within the elongated sliding hole while simultaneously rotating around the central shaft 104. An elastic element 103, fitted onto the central shaft 104, is located between the end of the central shaft 104 away from the guide shaft 102 and the bracket 200. The handle recess 300 is fixedly mounted relative to the bracket 200, and a retaining ring 109 is provided on the central shaft 104 to axially limit the end of the central shaft 104 away from the guide shaft 102. Specifically, the retaining ring 109 is detachably mounted on the central shaft 104 and contacts the side of the second limiting groove 205 to achieve axial limiting of the central shaft 104. (See attached diagram) Figure 4 The bracket 200 is provided with a first limiting part 201, a second limiting part 202, a third limiting part 203, and a fourth limiting part 204. The first limiting part 201 and the second limiting part 202 together form a through hole for the central shaft 104 to pass through. The third limiting part 203 and the fourth limiting part 204 together form a through hole for the central shaft 104 to pass through. The first limiting part 201 and the second limiting part 202 are staggered along the axial direction of the central shaft 104, and the third limiting part 203 and the fourth limiting part 204 are staggered along the axial direction of the central shaft 104. The first limiting part 201 and the fourth limiting part 204 are located on one side of the central shaft 104, and the second limiting part 202 and the third limiting part 203 are located on the other side of the central shaft 104. Here, "one side of the central shaft 104" means that they are located on the same side with the axis as the boundary. The distance between the first limiting part 201 and the fourth limiting part 204 is greater than the distance between the second limiting part 202 and the third limiting part 203. The second limiting part 202 is pressed against the side of the rotating body 101 to achieve axial limiting of the central shaft 104 with the cooperation of the retaining ring 109. The bracket 200 is provided with a clearance hole 206, which is used to provide clearance space for the guide shaft 102 to slide along the handle body 400.

[0050] When installing the rotating mechanism 100 of this utility model, please refer to the attached diagram. Figure 10-12 First, fit the elastic element 103 onto the end of the central shaft 104 away from the guide shaft 102. Then, insert this end at an angle into the through hole between the third limiting part 203 and the fourth limiting part 204. After inserting it a certain length, place the central shaft 104 horizontally. Then, continue to move the central shaft 104 along the through hole between the third limiting part 203 and the fourth limiting part 204. At this time, when the other end of the central shaft 104 avoids the first limiting part 201 and the second limiting part 202, the end of the central shaft 104 close to the guide shaft 102 can be inserted into the through hole of the first limiting part 201 and the second limiting part 202. Then, install the retaining ring 109 and press it against the side of the second limiting groove 205 to limit the end of the central shaft 104 away from the guide shaft 102, thus completing the installation. When the door handle is mechanically opened in an emergency, the operator applies force to the handle body 400, causing the handle body 400 to rotate around the bracket 200. At the same time, the guide shaft 102 of the rotating mechanism 100 slides along the elongated hole on the bracket 200 and rotates around the central axis 104. As a result, the rotating body 101 rotates around the central axis 104, which drives the pull cable hole 106 to rotate around the central axis 104, thereby driving the pull cable to move. The other end of the pull cable tightens the mechanical unlocking mechanism, completing the mechanical unlocking.
