[0022] Secondly, this application also provides a vehicle door, including the handle assembly described above.

[0023] Thirdly, this application also provides a vehicle, including the door as described above.

[0024] The embodiments of this application have the following advantages:

[0025] This application discloses a handle assembly, which includes a base, a handle component, a transmission mechanism, a drive mechanism, and a reset mechanism. The base has a receiving cavity and is provided with a partition, which divides the receiving cavity into a first receiving groove and a second receiving groove. The handle component is hinged to the base via a first pivot and can be housed in the first receiving groove to achieve a concealed function of the handle component, effectively improving aesthetics, reducing the probability of the handle component being damaged, and effectively reducing wind resistance and energy consumption during vehicle operation.

[0026] The transmission mechanism, housed within the second receiving groove, includes a sliding member, a driven arm, and an unlocking arm. The driven arm is fixedly connected to the first rotating shaft, enabling the driven arm, the third rotating shaft, and the handle to rotate synchronously. The sliding member is slidably disposed within the second receiving groove and abuts against the end of the driven arm furthest from the first rotating shaft. This allows the sliding member to drive the driven arm to rotate around the axis of the first rotating shaft, thereby causing the third rotating shaft and the handle to rotate synchronously, enabling the handle to extend from the first receiving groove. The unlocking arm is hinged to the base via the second rotating shaft. The end of the driven arm furthest from the first rotating shaft has a protrusion, and the unlocking arm has a recess that matches the protrusion. When the handle extends from the first receiving groove, the user can place their hand between the handle and the first receiving groove and pull the handle in a direction away from the first receiving groove. This causes the handle to rotate around the axis of the first rotating shaft by a preset angle, simultaneously driving the third rotating shaft and the driven arm to rotate synchronously. This causes the protrusion of the driven arm to press against the recess of the unlocking arm, causing the unlocking arm to rotate in a direction away from the driven arm. The rotational stroke of the unlocking arm can be converted into the stroke along the length of the door lock's pull cord, causing the door lock to be pulled and unlocked, thus enabling the door to be opened.

[0027] The reset mechanism includes a first torsion spring and a second torsion spring, which are respectively sleeved on the first and second rotating shafts. After the door is opened, the user's hand leaves the handle, and the driven arm, the third rotating shaft, and the handle automatically rotate and reset to the extended state under the reset force of the first torsion spring. At the same time, the unlocking arm automatically rotates and resets under the reset force of the second torsion spring, thus resetting the door lock and realizing the function of closing the door. This ensures that the protrusion of the driven arm and the recess of the unlocking arm are in a near-separation state.

[0028] The output end of the drive mechanism is connected to the slider to enable the slider to reciprocate linearly within the second receiving groove. When the output end of the drive mechanism extends, it drives the slider to slide towards the driven arm, thereby causing the driven arm to rotate around the axis of the first rotating shaft, and further causing the handle to rotate around the axis of the first rotating shaft, thus enabling the handle to automatically extend from the first receiving groove. When the vehicle starts moving, the vehicle body sends a signal to the drive mechanism, and the output end of the drive mechanism retracts and resets. When the output end of the drive mechanism retracts, it drives the slider to slide away from the driven arm. Under the reset force of the first torsion spring, the driven arm, the third rotating shaft, and the handle automatically rotate and reset to the hidden state, thus enabling the handle to automatically retract and hide into the first receiving groove. By setting up a drive mechanism, a transmission mechanism, and a reset mechanism, the function of automatically extending or automatically retracting the handle into the first receiving groove is achieved. The structure is simple and improves the smoothness and stability of the handle's extension or retraction.

[0080] like Figures 1 to 17 As shown, an embodiment of this application provides a handle assembly 100, mainly used in vehicle doors. The handle assembly 100 includes a base 110, a handle component 120, a transmission mechanism 130, a drive mechanism 140, and a reset mechanism 150.

[0081] The base 110 has a receiving cavity 111 and is provided with a partition 112, which divides the receiving cavity 111 into a first receiving groove 1111 and a second receiving groove 1112. The handle 120 can be received in the first receiving groove 1111 and is hinged to the base 110 via a first pivot 121.

[0082] The transmission mechanism 130 is disposed within the second receiving groove 1112. The transmission mechanism 130 includes a sliding member 131, a driven arm 132, and an unlocking arm 133. The driven arm 132 is fixedly connected to the first rotating shaft 121. The sliding member 131 is slidably disposed within the second receiving groove 1112 and abuts against the end of the driven arm 132 away from the first rotating shaft 121. The unlocking arm 133 is hinged to the base 110 via the second rotating shaft 1332. The end of the driven arm 132 away from the first rotating shaft 121 has a protrusion 1321, and the unlocking arm 133 has a recess 1331 adapted to the protrusion 1321. The end of the unlocking arm 133 away from the second rotating shaft 1332 is used to connect to the pull cord 310 of the door lock 300.

[0083] See also Figure 18 The output end of the drive mechanism 140 is connected to the slider 131, and is used to drive the slider 131 to slide within the second receiving groove 1112, thereby causing the driven arm 132 to rotate around the axis of the first rotating shaft 121, and thus causing the handle 120 to rotate around the axis of the first rotating shaft 121. The reset mechanism 150 includes a first torsion spring 151 and a second torsion spring 152, the first torsion spring 151 being sleeved on the first rotating shaft 121, and the second torsion spring 152 being sleeved on the second rotating shaft 1332.

[0084] The handle assembly 100 provided in this application embodiment has a base 110 with a receiving cavity 111 and a partition 112. The partition 112 divides the receiving cavity 111 into a first receiving groove 1111 and a second receiving groove 1112. The first receiving groove 1111 is located on the outside of the base 110, and the second receiving groove 1112 is located on the inside of the base 110. The handle component 120 is hinged to the base 110 via a first pivot 121 and can be housed in the first receiving groove 1111 to achieve the function of hiding the handle component 120, effectively improving aesthetics, reducing the probability of the handle component 120 being damaged, and effectively reducing wind resistance and energy consumption during vehicle operation.

[0085] The transmission mechanism 130 is disposed within the second receiving groove 1112 and includes a sliding member 131, a driven arm 132, and an unlocking arm 133. The driven arm 132 is connected to the first rotating shaft 121 via a key connection, screw connection, interference fit, or integral molding, allowing the driven arm 132, the third rotating shaft 1322, and the handle 120 to rotate synchronously. The sliding member 131 is slidably disposed within the second receiving groove 1112 and abuts against the end of the driven arm 132 away from the first rotating shaft 121. This allows the sliding member 131 to slide towards the driven arm 132, driving the driven arm 132 to rotate around the axis of the first rotating shaft 121, thereby causing the third rotating shaft 1322 and the handle 120 to rotate synchronously, enabling the handle 120 to extend from the first receiving groove 1111. The unlocking arm 133 is hinged to the base 110 via the second pivot 1332. The driven arm 132 has a protrusion 1321 at one end away from the first pivot 121, and the unlocking arm 133 has a recess 1331 that matches the protrusion 1321. When the handle 120 extends from the first receiving groove 1111, the user can place their hand between the handle 120 and the first receiving groove 1111 and pull the handle 120 in a direction away from the first receiving groove 1111. This causes the handle 120 to rotate around the axis of the first rotating shaft 121 by a preset angle, simultaneously driving the third rotating shaft 1322 and the driven arm 132 to rotate synchronously. This causes the protrusion 1321 of the driven arm 132 to press against the recess 1331 of the unlocking arm 133, causing the unlocking arm 133 to rotate in a direction away from the driven arm 132. The rotational stroke of the unlocking arm 133 can be converted into the stroke of the pull rope 310 of the door lock 300 along its length, causing the door lock 300 to be pulled and unlocked, thus enabling the door to be opened.

[0086] The reset mechanism 150 includes a first torsion spring 151 and a second torsion spring 152, which are respectively sleeved on the first rotating shaft 121 and the second rotating shaft 1332. After the door is opened, the user's hand leaves the handle 120. The driven arm 132, the third rotating shaft 1322, and the handle 120 automatically rotate and reset to the extended state under the reset force of the first torsion spring 151. At the same time, the unlocking arm 133 automatically rotates and resets under the reset force of the second torsion spring 152, thereby resetting the door lock and realizing the function of closing the door. This makes the protrusion 1321 of the driven arm 132 and the recess 1331 of the unlocking arm 133 in a near-separation state.

[0087] The output end of the drive mechanism 140 is connected to the slider 131 to drive the slider 131 to reciprocate linearly within the second receiving groove 1112. When the output end of the drive mechanism 140 extends, it drives the slider 131 to slide towards the driven arm 132, thereby causing the driven arm 132 to rotate around the axis of the first rotating shaft 121, and further causing the handle 120 to rotate around the axis of the first rotating shaft 121, thus realizing the function of automatically extending the handle 120 from the first receiving groove 1111. When the vehicle starts driving, the vehicle body sends a signal to the drive mechanism 140, and the output end of the drive mechanism 140 retracts and resets. When the output end of the drive mechanism 140 retracts, it drives the slider 131 to slide away from the driven arm 132. Under the reset force of the first torsion spring 151, the driven arm 132, the third rotating shaft 1322, and the handle 120 automatically rotate and reset to the hidden state, thus realizing the function of automatically hiding and retracting the handle 120 into the first receiving groove 1111. By setting up a drive mechanism 140, a transmission mechanism 130, and a reset mechanism 150, the handle 120 can automatically extend from the first receiving groove 1111 or automatically retract into the first receiving groove 1111. The structure is simple and improves the smoothness and stability of the extension or retraction of the handle 120.

[0088] It should be noted that when the handle 120 needs to be retracted into the first receiving slot 1111 (e.g., during vehicle driving or parking), the output end of the drive mechanism 140 is not activated, the output end of the drive mechanism 140 is in a retracted state, and all components are in a reset state.

[0089] The handle 120 and driven arm 132 are designed as separate units. The handle 120 is located in the first receiving groove 1111, and the driven arm 132 is located in the second receiving groove 1112. The handle 120 and the driven arm 132 rotate synchronously via the first rotating shaft 121. This design eliminates the need for a large hole in the base 110, requiring only a relatively small diameter shaft hole. This effectively prevents dust and water from entering the second receiving groove 1112 from the first receiving groove 1111 when the handle 120 is unscrewed, resulting in better waterproofing and dustproofing and significantly improved sealing performance.

[0090] For example, the drive mechanism 140 can be a linear actuator motor, the first shaft 121 and the second shaft 1332 can both be pins, the slider 131 can be a slider, and the handle 120 can be a car door handle.

[0091] like Figure 4 , Figure 8 , Figure 13 , Figure 38 and Figure 39As shown, in one embodiment of this application, optionally, the driven arm 132 is provided with a third rotating shaft 1322 at one end away from the protrusion 1321. The third rotating shaft 1322 is located in the circumferential direction of the first rotating shaft 121. The handle 120 is connected to the driven arm 132 through the third rotating shaft 1322. The handle 120 is provided with a third receiving groove 122. The first torsion spring 151 is disposed in the third receiving groove 122 and is located at the middle position in the axial direction of the first rotating shaft 121.

[0092] In this embodiment, a third rotating shaft 1322 is provided at the end of the driven arm 132 away from the protrusion 1321, and the third rotating shaft 1322 is located circumferentially to the first rotating shaft 121, so that the handle 120 can be connected to the driven arm 132 through the third rotating shaft 1322. Specifically, one end of the third rotating shaft 1322 is placed in the shaft hole of the driven arm 132, and the driven arm 132 may be provided with a limiting buckle for restricting the movement of the third rotating shaft 1322. The other end of the third rotating shaft 1322 passes through the base clearance hole and connects to the shaft hole of the handle 120, so that the handle 120 can rotate around the first rotating shaft 121 under the action of the third rotating shaft 1322. Utilizing the lever principle, it is beneficial to drive the handle 120 to rotate around the axis of the first rotating shaft 121, thereby realizing the function of extending or retracting the handle 120.

[0093] During the extension process, when the slider 131 slides toward the driven arm 132, it can drive the driven arm 132 to rotate around the axis of the first rotating shaft 121. At the same time, the third rotating shaft 1322 connected to the driven arm 132 rotates around the first rotating shaft 121, thereby driving the third rotating shaft 1322 and the handle 120 to rotate synchronously, realizing the function of the handle 120 extending out of the first receiving groove 1111.

[0094] When the handle 120 extends from the first receiving groove 1111, the user can place their hand between the handle 120 and the first receiving groove 1111 and pull the handle 120 in a direction away from the first receiving groove 1111. This causes the handle 120 to rotate around the axis of the first rotating shaft 121 by a preset angle, which in turn drives the third rotating shaft 1322 to rotate around the axis of the first rotating shaft 121. This causes the driven arm 132 to rotate around the axis of the first rotating shaft 121, so that the protrusion 1321 of the driven arm 132 presses the recess 1331 of the unlocking arm 133, causing the unlocking arm 133 to rotate in a direction away from the driven arm 132. The rotational stroke of the unlocking arm 133 can be converted into the stroke of the pull rope 310 of the door lock 300 in the length direction, so that the door lock 300 is pulled and the door is unlocked, thus realizing the function of opening the door.

[0095] By creating a third receiving groove 122 on the handle 120 to accommodate the first torsion spring 151, the usable space of the handle 120 is effectively utilized, saving space while ensuring that the first torsion spring 151 is subjected to uniform force. This reduces the overall size of the handle assembly 100 and improves the smoothness and stability of the handle 120's return rotation. Furthermore, by positioning the first torsion spring 151 at the midpoint of the axial direction of the first rotating shaft 121, the uniformity of force on the first torsion spring 151 is further improved, further enhancing the smoothness and stability of the handle 120's return rotation.

[0096] like Figure 25 , Figure 26 and Figure 27 As shown, in one embodiment of this application, optionally, the sliding member 131 is provided with a first arc-shaped abutment portion 1311, and the driven arm 132 is provided with a second arc-shaped abutment portion 1323. The first arc-shaped abutment portion 1311 and the second arc-shaped abutment portion 1323 are in line contact abutment. The first arc-shaped abutment portion 1311 is provided with a first oil storage groove 13111, and the second arc-shaped abutment portion 1323 is provided with a second oil storage groove 13231 that is adapted to the first oil storage groove 13111.

[0097] In this embodiment, by setting the first arc-shaped abutment portion 1311 of the sliding member 131 to make line contact with the second arc-shaped abutment portion 1323 of the driven arm 132, and the first arc-shaped abutment portion 1311 having a first oil reservoir 13111, and the second arc-shaped abutment portion 1323 having a second oil reservoir 13231 adapted to the first oil reservoir 13111, excess lubricating oil on the arc surface can accumulate in the oil reservoir, reducing lubricating oil consumption. At the same time, the lubricating oil keeps the first arc-shaped abutment portion 1311 and the second arc-shaped abutment portion 1323 lubricated, effectively reducing the sliding friction between them. This makes the sliding member 131 and the driven arm 132 move more smoothly, improving movement stability and smoothness, effectively reducing noise and component wear caused by friction, improving user experience and extending product life.

[0098] like Figure 4 , Figure 8 , Figure 13 and Figure 26 As shown, in one embodiment of this application, optionally, the base 110 is provided with a slide rail 113, the sliding member 131 slides in contact with the slide rail 113, the sliding member 131 is provided with a groove 1312 adapted to the slide rail 113, the groove wall of the groove 1312 is provided with protrusions 13121, so that the groove 1312 and the slide rail 113 are in line contact and define a third oil storage groove, and the contact surface between the sliding member 131 and the base 110 is provided with a fourth oil storage groove, so that the sliding member 131 and the base 110 are in line contact.

[0099] In this embodiment, a slide rail 113 is provided on the base 110, and a slide groove 1312 adapted to the slide rail 113 is provided on the sliding member 131, allowing the sliding member 131 to slide in contact with the slide rail 113. By providing protrusions 13121 on the groove wall of the slide groove 1312, the slide groove 1312 and the slide rail 113 form a line contact and define a third oil reservoir. Simultaneously, a fourth oil reservoir is provided on the contact surface between the sliding member 131 and the base 110, allowing the sliding member 131 to make line contact with the base 110. This effectively reduces the sliding friction between the sliding member 131 and the base 110, making the sliding member 131 more stable during sliding, improving sliding stability and smoothness, effectively reducing noise and component wear caused by friction, improving user experience, and extending product lifespan.

[0100] like Figure 4 , Figure 8 , Figure 13 , Figure 31 , Figure 32 and Figure 33 As shown, in one embodiment of this application, optionally, the base 110 is provided with a guide portion 114, and the end of the unlocking arm 133 away from the second rotating shaft 1332 is provided with a sliding portion 1333 that cooperates with the guide portion 114. The sliding portion 1333 slides in contact with the guide portion 114, and the sliding portion 1333 is in line contact with the guide portion 114.

[0101] Understandably, during the rotation of the unlocking arm 133 around the axis of the second pivot 1332, the guide portion 114 acts as a guide, allowing the sliding portion 1333 of the unlocking arm 133 to move along the guide portion 114. This improves the stability and smoothness of the unlocking arm 133's movement, thereby enhancing the service life of the handle assembly 100 and its product competitiveness. By setting the sliding portion 1333 and the guide portion 114 to make line contact, the contact area between them can be minimized, thereby reducing frictional resistance, reducing frictional noise, and minimizing wear.

[0102] like Figure 4 , Figure 19 , Figure 20 , Figure 21 , Figure 22 , Figure 23 and Figure 24As shown, in one embodiment of this application, optionally, the handle assembly 100 further includes an inertial element 160 and an elastic element 163. The unlocking arm 133 has an assembly hole 1334 adapted to the inertial element 160 and the elastic element 163 along the axial direction of the second rotating shaft 1332. A first flange 13341 and a second flange 13342 are formed on the wall of the assembly hole 1334. The inertial element 160 includes a head 161 and a rod 162. The head 161 is located between the first flange 13341 and the second flange 13342. The rod 162 passes through the assembly hole 1334. The elastic element 163 abuts against the head 161 and the second flange 13342 respectively. The end of the rod 162 away from the head 161 is provided with an abutment portion 1621. The base 110 is provided with a limiting portion 115 adapted to the abutment portion 1621.

[0103] Understandably, in its natural state, the head 161 of the inertial member 160 abuts against the first flange 13341 under the action of the elastic member 163. The first flange 13341 is used to prevent the inertial member 160 from disengaging from the mounting hole 1334. When the door is impacted by an external force during vehicle operation, the impact force forces the unlocking arm 133 to rotate away from the driven arm 132. At this time, under the action of inertial force, the abutting part 1621 of the inertial member 160 can move towards the base 110 and abut against the limiting part 115 of the base 110 when the unlocking arm 133 rotates to a preset angle, thereby limiting the unlocking arm 133 from continuing to rotate away from the driven arm 132. This prevents the door lock pull rope from reaching the preset stroke, achieving the purpose of preventing the door from being opened accidentally and effectively improving safety performance. During this process, the elastic member 163 is compressed. This technology avoids the problem of the car door accidentally opening due to inertia when it is hit by an external force while the vehicle is in motion, thus preventing injury to the human body.

[0104] After the vehicle body is impacted by an external force, the inertial member 160 returns to its natural state under the restoring force of the elastic member 163. That is, under the action of the elastic member 163, the head 161 of the inertial member 160 abuts against the first flange 13341, causing the abutting portion 1621 of the inertial member 160 to move away from the limiting portion 115 of the base 110. This allows the unlocking arm 133 to rotate away from the driven arm 132, enabling the door lock pull cord to reach a preset stroke, thereby allowing the door to open normally. For example, the elastic member 163 can be a cylindrical spring or a leaf spring.

[0105] Optionally, the limiting part 115 can be a limiting groove or a limiting protrusion. The limiting part 115 is not limited to the specific structure described above. As long as it can cooperate with the abutment part 1621 to restrict the rotation of the unlocking arm 133, the specific structure of the limiting part 115 is not limited here.

[0106] like Figure 28 , Figure 29 and Figure 30 As shown, in one embodiment of this application, optionally, the handle component 120 includes a handle body 123 and a handle cover 124. The handle body 123 has a first slot 1233 on its outer periphery, and the handle cover 124 has a first buckle 1244 on its inner periphery that engages with the first slot 1233. One end of the handle body 123 has a second slot 1231, and the other end has a limiting rib 1232. One end of the handle cover 124 has a second buckle 1241, and the other end has an abutment 1242. The second buckle 1241 engages with the second slot 1231, and the abutment 1242 abuts against the side of the limiting rib 1232 facing the second slot 1231, so that the handle cover 124 is detachably connected to the handle body 123.

[0107] Specifically, the handle component 120 includes a handle body 123 and a handle cover 124. The handle body 123 has a first slot 1233 on its outer periphery, and the handle cover 124 has a first buckle 1244 on its inner periphery that engages with the first slot 1233. One end of the handle body 123 has a second slot 1231, and the other end has a limiting rib 1232. One end of the handle cover 124 has a second buckle 1241, and the other end has an abutment 1242. The second buckle 1241 engages with the second slot 1231, and the abutment 1242 abuts against the side of the limiting rib 1232 facing the second slot 1231, so that the handle cover 124 can be detachably connected to the handle body 123, making it convenient for users to install and remove the handle cover 124.

[0108] In this embodiment, the handle body 123 is rotatably connected to the base 110, thereby enabling the handle 120 to pop out and retract. The limiting rib 1232 can be integrally formed with the handle body 123 to reduce the manufacturing cost of the handle body 123 and improve the connection strength between the limiting rib 1232 and the handle body 123.

[0109] like Figure 28 , Figure 29 and Figure 30As shown in the above embodiments of this application, optionally, the abutment member 1242 includes an elastic part 12421 and a fixing part 12422. The fixing part 12422 is fixed between the handle cover 124 and the elastic part 12421. One end of the elastic part 12421 away from the fixing part 12422 abuts against the limiting rib 1232. The handle cover 124 is provided with a disassembly hole 1243, and the disassembly hole 1243 corresponds to the position of the elastic part 12421.

[0110] In this embodiment, the user can insert the rod 162 of the disassembly tool into the disassembly hole 1243 and push the elastic part 12421 of the abutment member 1242 by the rod 162, so that the elastic part 12421 is released from the restriction of the limiting rib 1232. After the elastic part 12421 is released from the limiting rib 1232, the user can easily release the second buckle 1241 from the second slot 1231 and the first buckle 1244 from the first slot 1233, thereby removing the entire handle cover 124. Therefore, by setting the disassembly hole 1243 and the elastic part 12421, the difficulty of disassembling the handle cover 124 can be reduced, thereby improving the disassembly efficiency of the handle cover 124.

[0111] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 34 , Figure 35 , Figure 36 , Figure 37 and Figure 42 As shown in one embodiment of this application, optionally, the handle assembly 100 further includes a retaining frame 170 and a sealing member 174. The retaining frame 170 is disposed in the first receiving groove 1111 and located circumferentially to the handle member 120. The sealing member 174 is connected to the retaining frame 170 and disposed circumferentially to the handle member 120. A sealing rib 1741 is provided on the side of the sealing member 174 away from the retaining frame 170. The sealing rib 1741 elastically abuts against the door sheet metal member 200. A plurality of surface difference positioning protrusions 171 are provided on the side of the retaining frame 170 away from the first receiving groove 1111 along the circumferential direction of the handle member 120. Each surface difference positioning protrusion 171 abuts against the door sheet metal member 200. A plurality of gap positioning protrusions 172 are provided along the circumferential inner surface of the retaining frame 170. Each gap positioning protrusion 172 abuts against the door sheet metal member 200.

[0112] In this embodiment, a sealing rib 1741 is provided on the side of the seal 174 away from the frame 170 for elastic contact with the door sheet metal 200. This compensates for errors and ensures sealing performance, preventing the sealing rib 1741 from not fitting properly due to accumulated manufacturing or assembly errors, which could lead to cavities and cause squeezing noises and water ingress when the door is closed. Multiple surface difference positioning protrusions 171 are provided along the circumference of the handle 120 on the side of the frame 170 away from the first receiving groove 1111. Each surface difference positioning protrusion 171 abuts against the door sheet metal 200 to ensure uniform surface difference between the door sheet metal 200 and the handle 120. Multiple gap positioning protrusions 172 are provided along the circumferential inner surface of the frame 170. Each gap positioning protrusion 172 abuts against the door sheet metal 200 to ensure uniform circumferential gap between the door sheet metal 200 and the handle 120, thus improving installation accuracy.

[0113] like Figure 4 , Figure 5 , Figure 40 and Figure 41 As shown, in one embodiment of this application, optionally, the first rotating shaft 121 divides the handle 120 into a first segment 125 and a second segment 126. The first segment 125 is provided with a positioning rib 1251 that abuts against the side wall 11111 of the first receiving groove 1111, so as to restrict the second segment 126 from swaying along the axial direction of the first rotating shaft 121.

[0114] In this embodiment, the first rotating shaft 121 divides the handle 120 into a first segment 125 and a second segment 126. The first segment 125 is provided with a positioning rib 1251 that abuts against the side wall 11111 of the first receiving groove 1111, so as to limit the second segment 126 of the handle 120 from swaying along the axial direction of the first rotating shaft 121, thereby playing a limiting role. This effectively reduces the swaying amplitude of the second segment 126 of the handle 120 along the axial direction of the first rotating shaft 121 during the process of extending or retracting into the first receiving groove 1111, thereby improving the stability, smoothness and position accuracy of the handle 120, and enhancing the user experience.

[0115] In one embodiment of this application, optionally, the base 110 is provided with a limiting buckle, which abuts against the end of the first rotating shaft 121.

[0116] In this embodiment, the base 110 is provided with a limiting buckle that abuts against the end of the first rotating shaft 121, so as to limit the first rotating shaft 121 by the limiting buckle. This makes the first rotating shaft 121 easy to assemble, reduces the number of parts, and lowers the cost.

[0117] like Figure 4 , Figure 8 and Figure 13As shown, in one embodiment of this application, optionally, the handle assembly 100 further includes a shock-absorbing component 180, which includes a first shock-absorbing pad 181, a second shock-absorbing pad 182, and a third shock-absorbing pad 183.

The first shock-absorbing pad 181 abuts against the drive mechanism 140 and the groove wall of the placement groove 11121. The second shock-absorbing pad 182 abuts against the side of the unlocking arm 133 near the driven arm 132. The third shock-absorbing pad 183 abuts against the side of the handle member 120 near the second receiving groove 1112.

[0118] In this embodiment, by providing a placement groove 11121 for placing the drive mechanism 140, and the groove wall of the placement groove 11121 being provided with positioning ribs to position the drive mechanism 140, the installation efficiency and accuracy of the drive mechanism 140 are improved. This, in turn, improves the accuracy of the output end of the drive mechanism 140 pushing the sliding member 131, thereby improving the rotational accuracy and stability of the driven arm 132. By placing the first shock-absorbing pad 181 between the drive mechanism 140 and the groove wall of the placement groove 11121, vibration of the drive mechanism 140 during operation is effectively prevented, noise is reduced, and the operational stability and service life of the drive mechanism 140 are improved. By placing the second shock-absorbing pad 182 against the side of the unlocking arm 133 near the driven arm 132, the unlocking arm 133 is reset and damped. By placing the third shock-absorbing pad 183 against the side of the handle 120 near the second receiving groove 1112, the handle 120 is reset and damped, effectively improving the user experience.

[0120] In this embodiment, by providing a damper and a rack adapted to the gear of the damper on the outer wall of the handle 120, the handle 120 can slowly and uniformly reset, improving the rotational stability of the handle 120 and reducing the noise generated by the impact between the handle 120 and the base 110. By placing the rack on the outer wall of the handle 120, space is effectively saved.

[0122] In this embodiment, a wire-passing hole communicating with the first receiving groove 1111 and the second receiving groove 1112 is provided on the partition 112 to facilitate the threading of the wire harness. By setting a sealing gasket that elastically abuts against the wall of the wire harness and the wire-passing hole, dust and water are effectively prevented from entering the second receiving groove 1112 from the first receiving groove 1111, thereby effectively improving the sealing performance.

[0123] In the above embodiments of this application, optionally, the card frame 170 is provided with a positioning rib on the side facing the first receiving groove 1111, and the groove wall of the first receiving groove 1111 is provided with a positioning groove that matches the positioning rib.
