DETAILED DESCRIPTION OF EXECUTION FORMS

[0024] The following describes various specific embodiments of the present disclosure with reference to the accompanying drawings, which form part of this description. It is understood that, although terms such as "front / front / front", "rear / rear / rear", "upper / upper / upper", "lower / lower / lower", "left", and "right" are used in the present disclosure to describe various exemplary structural components and elements, these terms are used here only for the sake of clarity and are derived from the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present disclosure can be arranged in various directions, these directional terms are merely illustrative and should not be considered as limitations.

[0025] Fig. Figure 1A shows a perspective view of a vehicle 100 with a door handle arrangement 110, and Fig. 1B and Fig. Figure 1C represents an overall structure of the door handle arrangement 110 according to an embodiment of the present disclosure. Fig. 1B is a front perspective view of the door handle assembly 110, and Fig. 1C is a rear perspective view of the door handle arrangement 110. Fig. 1D is a top-down view of the in Fig. 1C shows the door handle arrangement with the handle in a recessed position; Fig. 1E is a top view of the in Fig. 1C shows the door handle arrangement, with the handle in a provided position; and Fig. 1F is a top view of the in Fig. 1C shows the door handle arrangement, with the handle in an unlocked position.

[0026] As in Fig. As shown in Figure 1A, vehicle 100 has a vehicle door 101. The vehicle door 101 has an outer door surface 102. The door handle assembly 110 is a flush door handle assembly mounted in the vehicle door 101. The handle 111 (see Figure 1A) Fig. 1B-1F) of the door handle assembly 110 has a recessed position and a deployed position. When the handle 111 is in the recessed position, it is flush with the outer door surface 102 of the vehicle, so that it is concealed within the door and an operator cannot pull it. When the handle 111 is in the deployed position, it protrudes outwards from the outer door surface 102, allowing the operator to pull it.

[0027] As in Fig. 1B and Fig. As shown in Figure 1C, the door handle assembly 110 comprises the handle 111 and a handle receptacle 112. The handle receptacle 112 is mounted in the vehicle door 101. The handle 111 is mounted to the handle receptacle 112 from the front. The handle 111 is movable relative to the handle receptacle 112 and thus has a retracted position and an extended position.

[0028] Fig. 1D and Fig. Figure 1E shows two states of handle 111. Fig. Figure 1D is a top view of the door handle assembly 110 with the handle 111 in the recessed position, and Fig. Figure 1E is a top view of the door handle assembly 110 with the handle 111 in the provided position. As shown in Fig. As shown in Figure 1D, when the handle 111 is in the recessed position, the handle 111 is received in the handle receptacle 112, with the exception of the section of the handle that is flush with the outer door surface 102 of the vehicle. As shown in Fig. As shown in Figure 1E, the handle 111 is formed with a grip piece 117. When the handle 111 is in the provided position, the grip piece 117 extends out of the handle receptacle 112, allowing the operator to grasp the grip piece 117 with their hand to pull the handle 111.

[0029] In addition to the recessed and extended positions, handle 111 also includes other positions. For example, in Fig. As shown in Figure 1D, when the handle 111 is in the retracted position, the operator presses the handle 111 to move it inwards towards the inside of the handle receptacle 112 to reach a deployment release position. In the deployment release position, a drive device can be triggered to initiate the movement of the handle 111 relative to the handle receptacle 112 for deployment. When the handle 111 is in the deployment release position, the entire handle 111 is received in the handle receptacle 112, and the handle 111 is recessed inwards relative to the outer door surface 102 of the vehicle.

[0030] Furthermore, as in Fig. As shown in Figure 1E, when the handle 111 is in the provided position, the operator pulls the handle 111 to move it towards the outside of the handle receptacle 112 in order to engage the Fig. To reach the unlocked position shown in 1F. As in Fig. As shown in Figure 1F, the handle 111 is further positioned in the unlocked position, so that most of the handle is exposed outside the handle receptacle 112. In this unlocked position, the handle 111 can trigger the opening of a vehicle door lock. Furthermore, the operator presses, as shown in Fig. Figure 1E shows the handle 111 in the provided position, to move the handle 111 towards the inside of the handle receptacle 112 to reach a lowering release position. In the lowering release position, the drive device can be triggered to initiate the movement of the handle 111 relative to the handle receptacle 112 for lowering.

[0031] Fig. 2A and Fig. Figure 2B shows the detailed structures of the door handle assembly in a front exploded view and a rear exploded view of the door handle assembly 110. As in Fig. 2A and Fig. As shown in Figure 2B, the door handle assembly 110 comprises, in addition to the handle receptacle 112 and the handle 111, the drive device 113, a handle shaft 118, a transmission device (comprising a transmission element 126 and an X-shaped joint structure 129), a locking cylinder 116, a release structure 125, a door locking connection structure 115 and a push-push structure 120.

[0032] The drive device 113 is, for example, a motor or an actuator with a motor. The handle shaft 118 rotates under the drive of the drive device 113. One end of the handle shaft 118 is fixedly connected to an output end 119 of the drive device 113. The other end of the handle shaft 118 is fixedly connected to the transmission device. The transmission device (which includes the transmission element 126 and the X-shaped joint structure 129) connects the handle shaft 118 to the handle 111 and the handle receptacle 112, so that the handle 111 can be driven by the handle shaft 118 to move between the retracted position and the extended position, and the transmission device can move to drive the handle shaft 118 to rotate when the operator operates the handle 111, thereby driving the output end 119 of the drive device 113 to rotate.The X-shaped joint structure 129 of the transmission device is connected to the handle 111 and the handle receptacle 112 and is designed to rotate about its axis of rotation 130 to allow the handle 111 to move relative to the handle receptacle 112 for deployment or retraction. The transmission element 126 of the transmission device connects the handle shaft 118 to the X-shaped joint structure 129, so that the X-shaped joint structure 129 can be driven to rotate by the drive unit 113 via the handle shaft 118. The X-shaped joint structure 129 rotates to drive the handle shaft 118 to rotate when the operator operates the handle 111, thereby driving the output end 119 of the drive unit 113 to rotate.

[0033] As in the Fig. 2A and Fig. As shown in Figure 2B, the handle receptacle 112 includes a receiving cavity 156, and the handle 111 can be arranged in the receiving cavity 156. A slot 144 is provided in a side wall of the handle 111. A through-opening 154 is provided in a corresponding side wall of the handle receptacle 112. The handle 111 includes a receiving cavity 157, which is formed in a different section of the handle 111 than the handle part 117. The transmission element 126 and the X-shaped joint structure 129 of the transmission device can be arranged in the receiving cavity 157.When the handle 111 is arranged in the receiving cavity 156 of the handle receptacle 112 and the transmission element 126 and the X-shaped joint structure 129 are arranged in the receiving cavity 157, one end 127 of the transmission element 126 passes successively through the slot 144 of the handle 111 and the through-opening 154 of the handle receptacle 112 and extends to the outside of the handle receptacle 112, thereby firmly connecting it to the other end of the handle shaft 118.

[0034] The X-shaped joint structure 129 comprises a first push rod 139 and a second push rod 140. The first push rod 139 and the second push rod 140 rotate about the axis of rotation 130 at an intersection point. The first push rod 139 comprises a first end 131 and a second end 132. The first end 131 is slidably connected to the handle receptacle 112, and the second end 132 is pivotally connected to the handle 111. The second push rod 140 comprises a third end 133 and a fourth end 134. The third end 133 is slidably connected to the handle 111, and the fourth end 134 is pivotally connected to the handle receptacle 112. In the receiving cavity 157 of the handle 111, the second push rod 140 is located closer to the side wall of the handle 111, which is provided with the slot 144, than the first push rod 139.The other end 128 of the transmission element 126 is slidably connected to the second push rod 140, and the end 127 of the transmission element 126 is fixedly connected to the handle shaft 118. The second push rod 140 includes a third connecting groove 148. The transmission element 126 is provided at its end 128 with a third connecting pin 153. The third connecting pin 153 is designed to slide within the third connecting groove 148. In one embodiment, as shown in a partially enlarged view of [Figure 1], the transmission element 126 is provided with a third connecting pin 153 at its end 128. Fig. As shown in Figure 2B (which shows a partial structure of the second push rod 140 from a different perspective), a receiving cavity 158 is formed in the second push rod 140. The receiving cavity 158 extends in an extension direction of the second push rod 140 and is designed to receive at least one section of the transmission element 126, including the end 128 of the transmission element 126. The receiving cavity 158 is connected to the third connecting groove 148. The third connecting groove 148 can consist of two opposing grooves. The end 128 of the transmission element 126 is movable within the receiving cavity 158, so that the third connecting pin 153 at the end 128 slides within the third connecting groove 148. This structure makes the door handle assembly 110 more compact.In other embodiments, the second push rod 140 may not have a receiving cavity 158, and the transmission element 126 is arranged outside the second push rod 140.

[0035] The handle receptacle 112 comprises a first connecting groove 152. The first push rod 139 of the X-shaped joint structure 129 is provided at its first end 131 with a first connecting pin 135. The first connecting pin 135 is designed to slide within the first connecting groove 152 of the handle receptacle 112. In one embodiment, the first connecting groove 152 is formed in a projection 151 on the underside of the handle receptacle 112. In other embodiments, the first connecting groove 152 may be provided in other suitable structures. The handle 111 comprises a second connecting groove 141. The second push rod 140 of the X-shaped joint structure 129 is provided at its third end 133 with a second connecting pin 137. The second connecting pin 137 is designed to slide within the second connecting groove 141. In one embodiment, the second connecting groove 141 is formed in a projection on an upper side section of the handle 111.In other embodiments, the second connecting groove 141 may be provided in other suitable structures. The handle 111 includes a first pivot hole 149. The first push rod 139 of the X-shaped joint structure 129 is provided at its second end 132 with a fourth connecting pin 136. The fourth connecting pin 136 is designed to pivot in the first pivot hole 149 of the handle 111. In one embodiment, the first pivot hole 149 is formed in a projection on a lower side section of the handle 111. In other embodiments, the first pivot hole 149 may be provided in other suitable structures. The handle receptacle 112 includes a second pivot hole 147. The second push rod 140 of the X-shaped joint structure 129 is provided at its fourth end 134 with a fifth connecting pin 138. The fifth connecting pin 138 is designed to pivot in the second pivot hole 147 of the handle receptacle 112.In one embodiment, the second pivot hole 147 is formed in a projection 146 on the underside of the handle receptacle 112. In other embodiments, the second pivot hole 147 can be provided in other suitable structures.

[0036] By providing the first connecting groove 152, the second connecting groove 141, the third connecting groove 148, the first pivot hole 149, and the second pivot hole 147, the handle 111 is recessed or positioned translationally relative to the handle receptacle 112; that is, the surface of the handle 111 remains parallel to or congruent with an initial position when the handle is moved relative to the handle receptacle 112, and the rotary motion of the drive device 113 is converted into the translational motion of the handle 111 relative to the handle receptacle 112. In one embodiment, the first connecting groove 152 is a linear groove, the second connecting groove 141 is a specifically curved groove, and the third connecting groove 148 is a specifically curved groove.Furthermore, due to the design of the X-shaped joint structure 129, the transmission element 126, the handle 111 and the handle receptacle 112, as described above, when the drive device 113 is activated to drive the handle shaft 118 to rotate, the transmission element 126 is driven to rotate by the handle shaft 118, the second push rod 140 of the X-shaped joint structure 129 is then driven by the transmission element 126 to rotate about the axis of rotation 130, and the first push rod 139 of the X-shaped joint structure 129 rotates accordingly about the axis of rotation 130, allowing the handle 111 to move relative to the handle receptacle 112 to be retracted or deployed.When the operator actuates the handle 111 to move it relative to the handle receptacle 112, the X-shaped joint structure 129 is also moved accordingly to drive the transmission element 126 to rotate by means of the second push rod 140, thereby driving the handle shaft 118 to rotate and ultimately driving the drive device 113 (e.g., its output end 119) to rotate. In other embodiments, the X-shaped joint structure 129, the transmission element 126, the handle 111, and the handle receptacle 112 can have other suitable structures to implement the aforementioned functions. The structural configurations of the transmission element 126 and the X-shaped joint structure 129 enable the connection of the drive device 113 and the handle 111.In the present disclosure, when the operator operates the handle 111 to trigger the lowering or provisioning of the handle or the unlocking of the vehicle door, the movement state or movement position of the handle 111 is determined according to the rotary movement of the drive device 113, whereupon the drive device 113 is activated to move in order to lower or provide the handle 111 or to activate a door locking switch 403 (see . Fig. 4) to unlock the vehicle door 101.

[0037] In the present disclosure, in addition to the electrical unlocking described above, the vehicle door can also be unlocked mechanically, for example, by means of the movements of the unlocking structure 125 and the door locking linkage structure 115. The unlocking structure 125 is rigidly connected to the door locking linkage structure 115, which is connected to a cord (not shown) for unlocking the vehicle door 101. The unlocking structure 125 is driven to rotate by the X-shaped joint structure 129, which in turn drives the door locking linkage structure 115 to rotate, and the door locking linkage structure 115 then drives the cord to move in order to mechanically unlock the vehicle door 101. When the handle 111 is in the retracted position, the unlocking structure 125 is not engaged with the X-shaped joint structure 129.When the handle 111 is in the deployed position, the release structure 125 begins to engage with the second push rod 140 of the X-shaped joint structure 129. When the operator pulls the handle 111 into the deployed position, the second push rod 140 rotates to drive the release structure 125 to rotate, and the door locking linkage structure 115 then rotates to drive the cord to move, thereby unlocking the vehicle door 101.

[0038] If the handle 111 experiences an electrical fault and cannot be deployed by means of an electrical drive (e.g., using the drive device 113), the handle 111 is mechanically pressed and, in the present disclosure, springs out (is deployed) by means of the push-push structure 120. The push-push structure 120 connects the handle 111 to the handle receptacle 112, so that the handle 111 can be moved by the operator from the retracted position to an intermediate position between the retracted position and the deployed position, or the handle 111 can be moved from the intermediate position to the retracted position. In one embodiment, the push-push structure 120 has a structure similar to the click structure of a ballpoint pen to implement a press-to-pop function.A base 142 is provided in the receiving cavity 157 of the handle 111, and an elastic element (not shown), such as a spring, is provided in the base 142. One end of the push-push structure 120 is partially received in the base 142 and rests against the elastic element in the base 142, and the other end of the push-push structure 120 rests against the underside of the handle receptacle 112. In one embodiment, the base 142 has a cylindrical projection that forms a receiving cavity for receiving the elastic element and the push-push structure 120. In other embodiments, other suitable push-push structures 120 can be used.

[0039] When handle 111 is in the recessed position, the operator pushes handle 111, causing the push-push structure 120 to be pushed inwards. The push-push structure 120 then pushes handle 111 outwards (in the opposite direction to the push direction) relative to handle receptacle 112 for a short stroke to expose handle 111. The operator can then pull handle 111 further outwards to expose handle 117. Holding handle 117, the operator pulls handle 111 outwards into the unlocked position, thereby actuating the release mechanism (e.g., pulling a cord) to unlock the vehicle door 101. The operator can then open the vehicle door 101. This emergency opening function of the vehicle door 101 is reusable.When the operator pushes the handle 111 into the recessed position in the unlocked position and further pushes the handle inwards by a short stroke, the push-push structure 120 moves to an initial state to hold the handle 111 in the recessed position. Accordingly, if an emergency opening of the vehicle door 101 is subsequently required, the push-push structure 120 can be actuated again in the manner described above for the "push-to-pop" of the handle 111.

[0040] The present disclosure further provides an additional emergency opening function for the vehicle door 101, namely, opening the vehicle door 101 by using a mechanical key. As described above, the X-shaped joint structure within the handle is compact, so that sufficient space is provided inside the handle to accommodate the lock cylinder. The handle 111 includes a removable handle cover 114. Fig. 2A and Fig. Figure 2B represents the handle cover 114 removed from the handle 111. The handle 111 includes an engagement section 143 designed to engage with a corresponding component (not shown) on the handle cover 114 in order to detachably mount the handle cover 114 to the handle 111. A first receiving section 145 is provided in the receiving cavity 156 of the handle receptacle 112. The first receiving section 145 is designed to receive the lock cylinder 116. The lock cylinder 116 can be opened by using the mechanical key to unlock the vehicle door 101. After the handle cover 114 has been removed from the handle 111, the lock cylinder 116 is exposed and can be used by the operator.In operation, the operator can press the handle 111 in the recessed position, the push-push structure 120 then pushes the handle 111 outwards for a short stroke (in the opposite direction to the direction of pressure), and the operator removes the handle cover 114, pushes the handle 111 back into the recessed position and inserts the mechanical key into the lock cylinder 116 to open the vehicle door 101.

[0041] Fig. Figure 2C presents a perspective view of the assembled unlocking structure 125 and the door locking connection structure 115 from a first perspective, and Fig. Figure 2D presents a perspective view of the assembled release structure 125 and the door locking connection structure 115 of the door handle assembly from a second perspective. As described above, when the handle 111 is in the recessed position, the release structure 125 is not engaged with the X-shaped joint structure 129. In this case, the release structure 125 must be held in its initial position to prevent it from becoming loose. The door locking connection structure 115 remains fixed in its initial position with the handle receptacle 112, so the release structure 125 remains in its initial position without disengaging when not engaged with the X-shaped joint structure 129.

[0042] As in the Fig. 2C and Fig. 2D as well as in the Fig. 1B and Fig. As shown in Figure 1C, the unlocking structure 125 comprises a main body 123 and an engagement section 124. The engagement section 124 can engage with the X-shaped joint structure 129. The main body 123 is essentially cylindrical. The unlocking structure 125 can rotate about a central axis of the main body 123. The engagement section 124 extends from one end of the main body 123. The other end of the main body 123 is rigidly connected to the door locking connection structure 115. According to the lever principle, the distance between the end 121 of the engagement section 124, which engages with the X-shaped joint structure 129, and the central axis of the main body 123 is greater than the radius of the main body 123, for example about twice the radius, so that less force is applied to the end 121 to drive the unlocking structure 125 to rotate in order to unlock the vehicle door.

[0043] The door locking connection structure 115 comprises a main body 159 and a retaining section. The retaining section allows the door locking connection structure 115 to remain firmly connected to the handle receptacle 112 in the initial position, for example, in a pre-tensioned manner. The main body 159 is essentially cylindrical. The door locking connection structure 115 can rotate about a central axis of the main body 159. One end of the main body 159 is rigidly connected to the other end of the main body 123 of the release structure 125. For example, a connection between the main body 159 and the main body 123 is provided with matching tooth structures 122A, 122B, which are arranged circumferentially so that the release structure 125 can cause the door locking connection structure 115 to rotate during rotation. For example, the retaining section of the door locking connection structure 115 comprises, as shown in the Fig. 2C and Fig. 2D as well as the Fig. 1B and Fig. Figure 1C shows a torsion spring 160 and a projection 161. The projection 161 extends radially from a side wall of the main body 159. The torsion spring 160 is arranged around the main body 159, with one end 165 of the torsion spring 160 bearing against the projection 161 and the other end 166 of the torsion spring 160 bearing against a projection 163 on the handle receptacle 112, so that the main body 159 of the door locking connection structure 115 remains firmly connected to the handle receptacle 112 in the initial position, i.e., the unlocking structure 125 remains in the initial position without disengaging. For example, the end 165 of the torsion spring 160 is received in a recessed section 162 of the projection 161, and the end 166 of the torsion spring 160 is received in a recessed section 164 of the projection 163. The projection 163 is arranged on an outer shell of the handle receptacle 112.In the initial position, the torsion spring 160 is pre-tensioned, for example, compressed, to hold the main body 159 of the door locking connection structure 115 under pre-tension against the handle receptacle 112. The pre-tension force generated by this pre-tension is relatively small, so that when unlocking is required, the operator can easily rotate the unlocking structure 125 by pulling the handle 111 to unlock the vehicle door 101. When the operator pulls the handle 111 into the prepared position, the second push rod 140 of the X-shaped joint structure 129 rotates to cause the unlocking structure 125 to rotate (see the counterclockwise direction shown in Figure 1). Fig. 1C and Fig. 2C and Fig. 2D) and the door locking connection structure 115 then rotates against the restoring force of the torsion spring to move the cord, thereby unlocking the vehicle door 101. Through the interaction of the unlocking structure 125 and the door locking connection structure 115 with the X-shaped joint structure 129, the present disclosure enables the handle 111 to be actuated to mechanically unlock the vehicle door 101. The unlocking structure 125 and the door locking connection structure 115 can be formed as a single piece. For example, the main body 123 and the main body 159 can be a single component. In other embodiments, the door handle assembly 110 comprises other suitable structures to implement the aforementioned function.

[0044] Fig. 3A-3D represent the assembly relationship of the components of the door handle assembly 110 at each position. Fig. 3A is a cross-sectional view along a first section line of the in Fig. 1D shown door handle arrangement 110, with the handle 111 in the recessed position; Fig. 3B is a cross-sectional view along a second section line of the in Fig. 1D shown door handle arrangement 110, with the handle 111 in the recessed position; Fig. 3C is a cross-sectional view of the in Fig. 1E door handle arrangement 110 shown, with the handle 111 in the provided position; and Fig. 3D is a cross-sectional view of the Fig. 1F shows the door handle arrangement 110, with the handle 111 in the unlocked position.

[0045] As in the Fig. 3A and Fig. As shown in Figure 3B, the first connecting pin 135 at the first end 131 of the first push rod 139, when the handle 111 is in the recessed position, is located on the left side of the first connecting groove 152 in the projection 151 of the handle receptacle 112, and the fourth connecting pin 136 at the second end 132 of the first push rod 139 is pivotable in the first pivot hole 149 (not shown) of the handle 111. The second connecting pin 137 at the third end 133 of the second push rod 140 is located on the left side of the second connecting groove 141 on the upper side section of the handle 111, and the fifth connecting pin 138 at the fourth end 134 of the second push rod 140 is pivotable in the second pivot hole 147 (not shown) in the projection 146 of the handle receptacle 112.The third connecting pin 153 at the end 128 of the transmission element 126 is located on the right side of the third connecting groove 148 of the second push rod 140. The release structure 125 is located above the second push rod 140 but does not engage with it. An upper end of the push-push structure 120 is received in and rests against the base 142 of the handle 111.

[0046] When the drive device 113 drives the handle 111 to raise it from the recessed position of the Fig. 3A and Fig. 3B into the provided position of the Fig. To move 3C, the end 128 of the transmission element 126 is driven by the drive device 113 to rotate counterclockwise. The third connecting pin 153 at the end 128 of the transmission element 126 then drives the second push rod 140 to rotate about the fifth connecting pin 138, and the second connecting pin 137 of the second push rod 140 moves toward one right side of the second connecting groove 141 of the handle 111. Similarly, the first push rod 139 pivots about the fourth connecting pin 136, and the first connecting pin 135 of the first push rod 139 moves toward the right side of the first connecting groove 152 of the handle receptacle 112. When the operator moves the handle 111 from the recessed position of the Fig. 3A and Fig. 3B into the provided position of Fig. When 3C is moved, the handle 111 is extended outwards to move the first push rod 139 and the second push rod 140 as described above, and the second push rod 140 drives the end 128 of the transmission element 126 by means of the third connecting groove 148 to rotate counterclockwise. When the handle 111 is moved from the extended position of Fig. 3C into the recessed position of Fig. 3A and Fig. When 3B is moved, the components of the door handle assembly perform 110 operations that are opposite to the operations described above.

[0047] As in Fig. As shown in Figure 3C, when the handle 111 is in the provided position, the third connecting pin 153 at the end 128 of the transmission element 126 is located essentially in the center of the third connecting groove 148 of the second push rod 140, the first connecting pin 135 of the first push rod 139 is located essentially in the center of the first connecting groove 152 of the handle receptacle 112, and the second connecting pin 137 of the second push rod 140 is located on the right side of the second connecting groove 141 of the handle 111. The end 121 of the release structure 125 begins to engage with the second push rod 140. The upper end of the push-push structure 120 is separated from the base 142 of the handle 111.

[0048] If the operator moves handle 111 from the provided position into Fig. 3C into the unlocked position Fig. When moved in 3D, the handle 111 is moved further outwards to drive the first push rod 139 to pivot around the fourth connecting pin 136, the first connecting pin 135 of the first push rod 139 moves further towards the right side of the first connecting groove 152 of the handle receptacle 112 and drives the second push rod 140 to pivot around the fifth connecting pin 138, the second connecting pin 137 of the second push rod 140 moves further towards the right side of the second connecting groove 141 of the handle 111, and the second push rod 140 drives the end 128 of the transmission element 126 further to rotate counterclockwise by means of the third connecting groove 148. The unlocking structure 125 is driven by the second push rod 140 to rotate clockwise in order to unlock the vehicle door 101 by means of the door locking connection structure 115.

[0049] As in Fig. In the 3D representation, when the handle 111 is in the unlocked position, the third connecting pin 153 at the end 128 of the transmission element 126 is located on the left side of the third connecting groove 148 of the second push rod 140, the first connecting pin 135 of the first push rod 139 is located on the right side of the first connecting groove 152 of the handle receptacle 112, and the second connecting pin 137 of the second push rod 140 is located on the right side of the second connecting groove 141 of the handle 111. The unlocking structure 125 (e.g., its end 121) engages with the second push rod 140 and rotates into the unlocked position, thereby unlocking the vehicle door 101. The upper end of the push-push structure 120 is still separated from the base 142 of the handle 111.

[0050] Although specific directions of rotation such as clockwise and counterclockwise have been described above, other suitable structures of the X-shaped joint structure 129 and the transmission element 126 can cause relevant components to rotate in other directions to perform the functions described above.

[0051] Fig. Figure 4 is a block diagram of elements of the door handle assembly 110 communicating with a control device 401 according to an embodiment of the present disclosure. As in Fig. As shown in Figure 4, the drive device 113 of the door handle assembly 110 comprises a first detection device 402. The door handle assembly 110 further comprises the control device 401, the door locking switch 403, and a second detection device 404. The drive device 113, the door locking switch 403, and the second detection device 404 are all communicatively connected to the control device 401.

[0052] The control device 401 controls the drive device 113 to rotate in either a first or a second direction, thus driving the handle 111 to lower or lower it. Furthermore, the control device 401 can monitor the drive device 113, receive signals indicating the direction and angle of rotation of the output end 119 of the drive device 113, obtain the positions of the drive device 113 and the handle 111 based on these signals, and control the drive device 113 as needed to control the movement of the handle 111.For example, when the handle 111 is in the retracted position, the drive device 113 is in its home position, and the output angle of its output end 119 is 0 degrees; and when the handle 111 is moved from the retracted position to the deployed position, the drive device 113 is in the deployed position, and the rotation angle of its output end 119 is, for example, 60 degrees. When the handle 111 is moved from the retracted position to the deployment release position, the drive device 113 (e.g., its output end 119) rotates with respect to the home position by a first predetermined angle (e.g., more than 1 degree) in the first direction of rotation; When the handle 111 is moved from the provided position to the lowering release position, the drive device 113 (e.g. its output end 119) rotates relative to the provided position by a second predetermined angle (e.g.more than 2 degrees) in the first direction of rotation; and when the handle 111 is moved from the provided position to the unlocked position, the drive device 113 (e.g. its output end 119) rotates with respect to the provided position by a third predetermined angle (e.g. more than 5 degrees) in the second direction of rotation.

[0053] For this purpose, the drive device 113 is provided with a first detection device 402 for detecting or receiving the rotation angle of the output end 119 of the drive device 113. In some embodiments, the first detection device 402 comprises, for example, a plurality of position sensors that can detect whether the output end 119 of the drive device 113 has reached the lowered position, the deployed position, the unlocked position, the lowering release position, the deployment release position, etc., and send the detected signals to the control device 401. In some embodiments, the first detection device 402 is, for example, an encoder, and the rotation angle of the output end 119 of the drive device 113 can be obtained by means of a pulse signal output by the encoder.

[0054] In some embodiments, the control device 401 for the direction of rotation of the output end 119 of the drive device 113 can obtain information about the direction of rotation of the output end 119 of the drive device 113 by controlling the direction of a current when the output end 119 of the drive device 113 is driven to rotate by the control device 401. When the output end 119 of the drive device 113 is rotated by a preset angle in response to the rotation of the handle shaft 118 when the operator operates the handle 111, the drive device 113 generates a feedback current, and the control device 401 can obtain information about the direction of rotation of the output end 119 of the drive device 113 by means of the direction of the feedback current. For this purpose, the door handle assembly 110 is further equipped with the second detection device 404.The second detection device 404 can detect the feedback current generated by the drive device 113 and send a signal to the control device 401, so that the control device 401 receives information about the direction of rotation of the output end 119 of the drive device 113.

[0055] Furthermore, the second detection device 404 can also detect the current generated by the drive device 113 in order to obtain an engagement signal for the drive device 113. For example, the engagement signal for the drive device 113 can be obtained by detecting whether the current of the drive device 113 exceeds a certain threshold for a specific period of time. The control device 401 receives the engagement signal for the drive device 113 from the second detection device 404 to enable a reverse rotation of the drive device 113, thereby preventing the drive device from continuing to rotate in its original direction and potentially trapping an object (such as a human hand) if the handle is blocked by the object. Therefore, the door handle arrangement 110, according to the present disclosure, has an anti-pinch function.

[0056] Furthermore, based on the received signals indicating the rotation angle and direction of rotation of the output end 119 of the drive device 113, the control device 401 can send an unlocking control signal to the door lock switch 403 to open the door lock switch 403, thus unlocking the vehicle door 101.

[0057] Fig. Figure 5 is a flowchart of a method 500 for actuating a door handle arrangement 110 according to an embodiment of the present disclosure. As in Fig. As shown in Figure 5, step 502 begins with the execution of the method for actuating a door handle arrangement 110, and then proceeds to step 504. In one embodiment, the execution begins with the method for controlling the operation of a door handle arrangement 110 by the control device 401.

[0058] In step 504, it is determined whether a handle 111 of the door handle assembly 110 is in a retracted position or in a deployed position. In one embodiment, for example, the control device 401 determines whether the handle 111 is in the retracted position or in the deployed position based on signals indicating an angle and direction of rotation of an output end 119 of a drive device 113. If it is determined that the handle 111 is in the retracted position, step 504 proceeds to step 506. In step 506, the control device 401 determines whether actuation of the handle 111 by an operator causes the output end 119 of the drive device 113 to rotate by a first predetermined angle in a first direction of rotation. Is the output end 119 of the drive device 113 rotated by the first predetermined angle (e.g., more than 1 degree) in the first direction of rotation (e.g., clockwise, as in Fig. 3A and Fig. (as shown in Figure 3B) is rotated, it is indicated that the operator has pressed the handle 111 to trigger the provision of the handle, and step 506 proceeds to step 508. In step 508, the control device 401 controls the rotation of the output end 119 of the drive device 113 in a second direction of rotation (e.g., counterclockwise, as shown in Figure 3B). Fig. 3A and Fig. (3B shown), to deploy the handle 111, and step 508 proceeds to step 510. In step 510, while the drive device 113 is driving the handle 111 to move it from the retracted position to the deployed position, the control device 401 determines whether the drive device 113 generates a pull signal. If the drive device 113 generates the pull signal, it is indicated that the deployment process of the handle 111 may collide with an object (e.g., a human hand), and step 510 proceeds to step 512. If the drive device 113 does not generate a pull signal, step 510 proceeds to step 514. In step 512, the control device 401 controls the rotation of the drive device 113 in the first direction of rotation, which is opposite to the second direction of rotation, in order to retract the handle 111, thereby preventing the process of deploying the handle 111 from colliding with the object (e.g. the human hand).Then step 512 proceeds to step 532, which terminates this process of controlling the handle 111 by the control device 401. In step 514, the control device 401 controls the drive device 113 to continue rotating in the second direction to provide the handle 111. Then step 514 proceeds to step 532, which terminates this process of controlling the handle 111 by the control device 401.

[0059] In step 504, when the control device 401 determines that the handle 111 is in the provided position, step 504 proceeds to step 516. In step 516, the control device 401 determines whether the operator's actuation of the handle 111 causes the output end 119 of the drive device 113 to rotate by a second predetermined angle in the first direction of rotation, by a third predetermined angle in the second direction of rotation, or to perform other rotations. If the output end 119 of the drive device 113 is rotated by the second predetermined angle (e.g., more than 2 degrees) in the first direction of rotation (e.g., clockwise, as in Fig. (as shown in Figure 3C) is rotated, it is indicated that the operator has pressed the handle 111 to trigger the retraction of the handle, and step 516 proceeds to step 518. In step 518, the control device 401 controls the rotation of the output end 119 of the drive device 113 in the first direction of rotation to retract the handle 111, and step 518 proceeds to step 520. In step 520, while the drive device 113 is driving the handle 111 to move it from the provided position to the retracted position, the control device 401 determines whether the drive device 113 generates a pull signal. If the drive device 113 generates the pull-in signal, it is indicated that the process of lowering the handle 111 could trap an object (e.g., a human hand), and step 520 proceeds to step 522. If the drive device 113 does not generate a pull-in signal, step 520 proceeds to step 524.In step 522, the control device 401 controls the rotation of the output end 119 of the drive device 113 in the second direction of rotation (e.g. counterclockwise, as in . Fig. (3C shown), which is opposite to the first direction of rotation to provide the handle 111, thus preventing the handle 111 from pinching the object (e.g., a human hand) during the lowering process. Then, step 522 proceeds to step 532, which terminates this process of controlling the handle 111 by the control device 401. In step 524, the control device 401 controls the output end 119 of the drive device 113 to continue rotating in the first direction of rotation to proceed with lowering the handle 111. Then, step 524 proceeds to step 532, which terminates this process of controlling the handle 111 by the control device 401.

[0060] In step 516, when it is determined that the output end 119 of the drive device 113 is rotated by the third predetermined angle (e.g., more than 5 degrees) in the second direction of rotation, it is indicated that the operator has pulled the handle 111 into the provided position to trigger the electrical unlocking, and step 516 proceeds to step 526. In step 526, the control device 401 generates an electrical unlocking control signal, and then step 526 proceeds to step 528. In step 528, the control device 401 outputs the electrical unlocking control signal to the door lock switch 403 to control the opening of the door lock switch 403, thus unlocking the vehicle door 101, and then step 528 proceeds to step 530. In step 530, the control device 401 controls the rotation of the output end 119 of the drive device 113 in the first direction of rotation (clockwise, as shown in Fig. (shown in 3D) to move the handle 111 from the unlocked position to the prepared position. After the vehicle door 101 is unlocked, the operator can pull the handle 111 into the prepared position to open the vehicle door 101. Then, step 530 proceeds to step 532, which terminates this process of controlling the handle 111 by the control device 401.

[0061] In step 516, when it is determined that the output end 119 of the drive device 113 performs other rotations, step 516 proceeds to step 532, thereby terminating the operation of the control of the handle 111 by the control device 401.

[0062] Fig. 6 is a block diagram of an embodiment of the in Fig. 4 control device 401 shown. As in Fig.As shown in Figure 6, the control device 401 comprises a bus 601, a processor 602, a memory 603, an input interface 604, and an output interface 605. The processor 602, the memory 603, the input interface 604, and the output interface 605 are connected to the bus 601. The processor 602 can read a program (or instruction) from the memory 603 and execute the program (or instruction) to process data. The processor 602 can also write data or the program (or instruction) to the memory 603. The memory 603 can store the program (instruction) or the data. By executing the instruction in the memory 603, the processor 602 can control the memory 603, the input interface 604, and the output interface 605.

[0063] The input interface 604 is designed to receive data about the rotation angle of the output end 119 of the drive device 113, which is received by the first detection device 402, and about the current generated by the drive device 113, which is received by the second detection device 404. The input interface 604 is further designed to convert the received data into data recognizable by the processor 602 via parameters and to output the data to the processor 602.

[0064] The processor 602 is designed to process (e.g., calculate) the received data in order to generate control signals. In one embodiment, the processor 602 processes the received data for the rotation angle of the output end 119 of the drive device 113 and for the current generated by the drive device 113 in order to generate the control signals to execute the steps of the method 500 described above.

[0065] The output interface 605 is designed to receive the control signals from the processor 602, to convert the control signals into the signals of the drive device 113 and to send the control signals to the drive device 113 in order to control the operation of the drive device 113 for extending or retracting the handle 111 or to control the operation of the door locking switch 403.
