For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0044] Figures 1A-1B Schematic diagram of two embodiments of the door lock device of this application. Figure 1A A first embodiment of a door lock device is shown. Figure 1BThe second embodiment of the door lock device is shown. In the first embodiment, the door lock device can be unlocked by applying a pulling force to the door (slider); in the second embodiment, the door lock device can be unlocked by actuating the lock block by an electromagnetic unlocking device.

[0045] The door lock device of the present application has a modular design, including a travel switch module and an electromagnetic pop-up module. The user can choose whether to install the electromagnetic pop-up module according to the needs, so that the door lock device can be switched between manual opening and automatic pop-up function to achieve automatic opening. Figure 1A The door lock device 100 with a door lock box structure is shown, and the electromagnetic opening module is Figure 1B The electromagnetic unlocking device 120 is shown in FIG.

[0046] like Figure 1A As shown, the door lock device 100 includes a door lock box 104, and a side of the door lock box 104 is provided with an electromagnetic unlocking device mounting hole 106 for selectively installing an electromagnetic pop-up module (electromagnetic unlocking device). The door lock box 104 is internally provided with a slider 112, a lock block 114 arranged above the slider 112, and a pair of locking arms 116 swingably arranged on the slider 112 to receive or release a component (such as a striker 101) for applying external thrust and external tension to the slider 112. The door lock box 104 is internally provided with a slider groove 132 extending in the horizontal direction to accommodate the slider 112 to move back and forth in the horizontal direction inside the door lock box. The slider 112 has a first position, a second position, and a third position located between the first position and the second position in its movement range. Among them, the first position is the door opening position, the second position is the door closing position, and the third position is the locking position. The locking position is the position of the slider 112 when the slider 112 and the locking block 114 are engaged with each other. The slider 112 can move from the first position to the third position under the action of the external thrust, and move from the second position to the first position under the action of the external pulling force.

[0047] Continue as Figure 1AAs shown, a slider engaging portion is provided on the upper right side of the slider 112. In the embodiment of the present application, the slider engaging portion is a slider locking groove 181, which allows the locking block 114 to be inserted and locked by the locking block 114, thereby driving the slider 112 to move. Those skilled in the art will appreciate that the slider engaging portion may also have other structures without violating the objectives of the present invention. The pair of locking arms 116 are provided at one end of the slider 112 (the left end in the figure) away from the slider engaging portion. During the reciprocating movement of the slider 112 between the door opening position and the door closing position, the pair of locking arms 116 can switch between an open state and a closed state, thereby releasing or engaging the striker 101 mounted on the door. An opening 148 is also provided on the left side of the door lock box 104, allowing the locking arms 116 to extend from the inside of the door lock box 104 to the outside of the door lock box 104 through the opening 148.

[0048] Continue as Figure 1A As shown, the lock block 114 has a locking portion 191 provided on the lower side for removably engaging with the slider locking groove 181 of the slider 112, thereby locking the slider 112. A first biasing device 193 is also provided in the door lock box 104 of the door lock device 100. A first biasing device mounting portion 192 is provided on the left side of the lock block 114 for mounting the first biasing device 193, such as an elastic member such as a compression spring. The first biasing device 193 is installed at a certain inclination angle with respect to the sliding direction of the slider 112, and can provide a first directional biasing force along the rightward movement direction of the lock block 114 and a third directional biasing force perpendicular to the rightward movement direction (e.g., downward movement).

[0049] Continue as Figure 1A As shown, a second biasing device is also provided within the door lock housing 104. A second biasing device mounting portion 182 is also provided on the underside of the slider 112 for mounting the second biasing device, such as one or more elastic components including a slider torsion spring 183 or a slider compression spring 184. Specifically, the second biasing device is installed between the second biasing device mounting portion 182 of the slider 112 and the door lock housing 104, and is used to apply a biasing force to the slider 112 to assist in its movement when the slider 112 moves leftward. Those skilled in the art will appreciate that the second biasing device can be any elastic component or biasing device disposed between the right side of the slider 112 and the door lock housing 104, such as a slider tension spring disposed between the left side of the slider 112 and the door lock housing 104, thereby providing a second biasing force for the slider 112 to slide leftward.

[0050] In the embodiment of the present application, the magnitude of the first-direction biasing force applied by the first biasing device 193 to the lock block 114 is configured to be greater than the magnitude of the second-direction biasing force applied by the second biasing device to the slider 112. This allows the slider 112 and the lock block 114 to move in a first direction (i.e., rightward in the figure) when the locking portion 191 of the lock block 114 is engaged with the slider locking groove 181 of the slider 112 and no external force is applied. In other words, the first biasing device 193 enables the lock block 114 to overcome the second-direction biasing force of the second biasing device and actuate the slider 112 to move in the same direction. During the process of the slider 112 moving rightward from the open position to the closed position, and while the locking portion 191 is engaged with the slider engagement portion, the first biasing device 193 can apply the first-direction biasing force to the slider, actuating the slider 112 to move rightward.

[0051] For ordinary technicians in this field, in some other embodiments, two biases can be set in the horizontal direction in Figure 1A (a direction parallel to the sliding direction of the slider 112) and the vertical direction in Figure 1A (a direction perpendicular to the sliding direction of the slider 112) to provide a first direction bias force and a third direction bias force respectively. These two biasing devices can be any form of elastic members as long as they can provide a bias force.

[0052] Continue as Figure 1A As shown, a blocking portion is also provided inside the door lock box 104. In the embodiment of the present application, the blocking portion is a pendulum block 117, which is rotatably mounted inside the door lock box 104 via a swing shaft 115. Accordingly, a pendulum block slot 134 matching the outer shape of the right side of the pendulum block 117 is provided inside the door lock box 104, so that the pendulum block 117 can swing back and forth around the swing shaft 115 in the pendulum block slot 134. A pendulum block abutment portion 194 is provided on the right side of the lock block 114 for abutting against the pendulum block 117. The specific structure of the pendulum block 117, and the cooperative movement relationship between the lock block 114 and the pendulum block 117 are described in detail in the following sections. Figures 2A-2B In other embodiments, the blocking portion may not be a pendulum block, but other types of structures.

[0053] like Figure 1BAs shown, to provide a selectable unlocking method, the door lock device 103 according to the second embodiment of the present application is further provided with an electromagnetic unlocking device 120. The electromagnetic unlocking device 120 extends into the door lock box 104 through the electromagnetic unlocking device mounting hole 106, thereby being removably connected to the lock block. In the embodiment in which the electromagnetic unlocking device 120 is installed, the door lock device 100 is further provided with a control device 160, which can communicate with the electromagnetic unlocking device 120 via a wired or wireless connection, thereby controlling the electromagnetic unlocking device 120 to drive the lock block 114, disengaging the locking portion 191 of the lock block 114 from the slider locking groove 181, thereby completing the unlocking operation of the door lock device. Users can choose whether the door lock device has an automatic unlocking function as needed. By directly installing or removing the electromagnetic unlocking device 120 from the door lock box 104, they can quickly and freely switch between manual unlocking and automatic unlocking.

[0054] Continue as Figure 1B As shown, the electromagnetic unlocking device 120 includes a lock block actuating rod 121, an electromagnetic pulse generator 122, and a power plug 123. The lock block actuating rod 121 is detachably attached to the lock block 114 in the vertical direction in the figure. Specifically, a T-shaped mounting slot (not shown) is provided on the right side of the lock block 114 along the thickness direction of the lock block (perpendicular to the page). This allows the head of the lock block actuating rod 121 to be retained within the T-shaped mounting slot. The lock block actuating rod 121 can also slide within the T-shaped mounting slot relative to the T-shaped mounting slot without affecting or restricting the movement of the lock block 114.

[0055] When unlocking the door, the control device 160 controls the electromagnetic pulse generator 122 to transmit an electromagnetic pulse signal to the lock block actuating rod 121, causing the lock block actuating rod 121 to move upward once. When the locking portion 191 of the lock block 114 is locked downward in the slider locking slot 181 of the slider 112, the electromagnetic pulse generator 122 transmits an electromagnetic pulse signal to activate the lock block actuating rod 121, driving the lock block 114 upward. This causes the locking portion 191 of the lock block 114 to move upward, releasing the slider 112. At this point, the slider 112 can be moved in a second direction (i.e., leftward in the figure) opposite the first direction under the biasing force of the second biasing device, causing the door of the electrical device to move toward opening, giving the user the sensation of the door being ejected. When the electromagnetic pulse signal disappears, the lock block 114 abuts the upper edge of the slider 112 in an unlocked position, where the locking portion 191 of the lock block 114 is not aligned with the slider locking slot 181 of the slider 112.

[0056] Figures 2A-2B This application Figure 1A and 1BThe partial views A0-1 and A0-2 of the part circled by the oval in the middle illustrate the specific structure of the pendulum block 117, the installation relationship of the lock block 114 in the door lock box 104, and the mutual movement relationship of the lock block 114 relative to the slider 112 and the pendulum block 117.

[0057] like Figures 2A-2B As shown above, the pendulum block 117 is rotatably mounted inside the door lock box 104 via the swing shaft 115. The pendulum block 117 has Figure 2A The first position of the pendulum block shown and Figure 2B The pendulum block is shown in its second position. The radially outer side (right side in the figure) of the pendulum block 117 includes a pendulum block protrusion 202. The radial outer contour (right side contour) of the pendulum block protrusion 202 is substantially arc-shaped, matching the arc-shaped groove of the pendulum block slot 134, allowing the pendulum block 117 to swing back and forth within the pendulum block slot 134 around the swing axis 115. The radially inner contour (left side contour) of the pendulum block protrusion 202 can abut the pendulum block abutment 194 of the locking block 114 in either the horizontal (lateral) or vertical (lateral) directions. Specifically, the radial inner contour of the pendulum block protrusion 202 includes a transverse abutment wall 204 and a longitudinal abutment wall 206, which are connected to each other at a certain angle. Specifically, the transverse abutment wall 204 extends downward or to the lower right from the top of the pendulum block protrusion 202, enabling transverse abutment with the pendulum block abutment portion 194. The longitudinal abutment wall 206 extends rightward from below the transverse abutment wall 204 at a certain angle, enabling vertical abutment with the pendulum block abutment portion 194. A longitudinal crosspiece 212 is provided on the upper side of the pendulum block chute 134 to limit the upward swing range of the pendulum block 117. A pendulum block torsion spring (not shown) is provided on the swing shaft 115 of the pendulum block 117 to provide a biasing force that causes the pendulum block 117 to swing toward the first position (downward).

[0058] Continue as Figures 2A-2B As shown, the door lock device 100 is further provided with an unlocking structure for disengaging the slider 112 and the lock block 114 from the engaged state (locked state). This allows the unlocking structure to disengage the locking portion 191 of the lock block 114 from the slider engagement portion of the slider 112 during movement of the lock block 114 in the second direction. The unlocking structure includes a guide portion and a guide surface that can abut against each other. In the embodiment of the present application, the guide portion is a guide pin 224, described below, and the guide surface is a second guide wall 236, described below. Those skilled in the art will appreciate that the unlocking structure may further include other structures without departing from the objectives of the present invention.

[0059] Specifically, the door lock housing 104 is provided with a stop pin 222 and a guide pin 224, which protrude from the bottom of the door lock housing 104. Accordingly, the lock block 114 is provided with a stop slot 232 corresponding to the stop pin 222. The lock block 114 is also provided with a first guide wall 234 and a second guide wall 236 facing the guide pin 224. The first guide wall 234 and the second guide wall 236 are smoothly connected to each other at a certain angle, forming a continuous guide surface that can abut against the guide pin 224. The first guide wall 234 and the second guide wall 236 have smooth surfaces, allowing the guide pin 224 to slide relative to the surfaces of the first guide wall 234 and the second guide wall 236.

[0060] The limiting groove 232 extends generally along the length of the locking block 114. The width of the limiting groove 232 is approximately equal to the outer diameter of the limiting pin 222, allowing the limiting pin 222 to be accommodated and slide within the limiting groove 232. Furthermore, the limiting groove 232 can rotate relative to the limiting pin 222, allowing the locking block 114 to swing while moving. The first guide wall 234 extends generally along the length of the locking block 114 and is located above the guide pin 224. This allows the guide pin 224 to limit the movement of the locking block 114 by restricting the movement of the first guide wall 234. The second guide wall 236 forms the left side of the locking portion 191. It has an arc-shaped outer profile and is located to the right of the guide pin 224, obliquely arranged relative to the second direction. In the embodiment of the present application, the second guide wall 236 extends approximately downward and rightward in an arcuate manner. Therefore, the movement of the locking block 114 is restricted by the interaction between the first and second guide walls 234, 236, and the guide pin 224 of the locking block 114. This is primarily reflected in the fact that the guide pin 224 can limit the downward movement range of the locking block 114. Furthermore, when the locking block 114 moves leftward, the guide pin 224 can abut against the inclined, arc-shaped second guide wall 236, causing the locking block 114 to tilt upward, thereby disengaging from the slider 112. Specifically, the second guide wall 236 is arranged at an angle relative to the direction of movement of the locking block 114. When the second guide wall 236 abuts the guide pin 224 and exerts an abutting force, the inclined, smooth surface of the second guide wall 236 slides relative to the guide pin 224, allowing the locking portion 191 of the locking block 114 to tilt upward under the action of the guide pin 224 and the second guide wall 236, thereby moving out of the slider locking slot 181.

[0061] like Figure 2AAs shown, in the first embodiment of the door lock device of the present application, in the door open state, since the first biasing device 193 applies a biasing force toward the lower right on the lock block 114, the pendulum block abutting portion 194 of the lock block 114 abuts to the right against the lateral abutting wall 204 of the pendulum block 117, and the locking portion 191 of the lock block 114 abuts downward against the slider abutting surface 242 on the right side of the slider 112, and the slider abutting surface 242 is located on the right side of the slider locking groove 181. When the slider 112 slides rightward until the slider locking groove 181 is aligned with the locking portion 191 of the locking block 114, the locking portion 191 of the locking block 114 can fall into the slider locking groove 181 under the action of the downward third directional biasing force of the first biasing device 193 and engage with it. At the same time, the swing block abutting portion 194 of the locking block 114 also moves downward, disengaging from the abutment with the transverse abutting wall 204 of the swing block 117 and moving to the lower side of the transverse abutting wall 204, thereby continuing to move rightward. Under the rightward biasing force of the first biasing device 193, the locking block 114 can drive the slider 112 to continue to move rightward in this state.

[0062] like Figure 2B As shown, in the second embodiment of the door lock device of the present application, when the lock block actuating rod 121 drives the lock block 114 to move upward, the locking portion 191 of the lock block 114 disengages from the slider locking groove 181, thereby unlocking the slider 112. The swing block abutment portion 194 of the lock block 114 moves upward and abuts against the longitudinal abutment wall 206 of the swing block 117, causing the swing block 117 to swing along the swing axis 115 toward the second swing block position. When the swing block 117 swings to the second swing block position, the swing block 117 abuts against the longitudinal cross-block portion 212 of the swing block slot 134, stopping the swinging. When the actuating force exerted by the lock block actuating rod 121 on the lock block 114 disappears, the pendulum block 117 swings toward the first pendulum block position (downward) under the biasing force of the pendulum block torsion spring, thereby abutting against the upper portion of the pendulum block abutting portion 194 of the lock block 114. Under the biasing force of the first biasing device 193, the lock block 114 tends to move downward and rightward, causing the locking portion 191 of the lock block 114 to abut downward against the slider abutting surface 242 of the slider 112. At this point, under the biasing force of the first biasing device 193, the pendulum block abutting portion 194 of the lock block 114 abuts rightward against the radial inner contour below the longitudinal abutting wall 206 of the pendulum block protrusion 202, and the lock block 114 moves laterally (horizontally) to its rightmost position. When the slider 112 slides to the right so that the slider locking groove 181 is aligned with the locking portion 191 of the locking block 114, the locking portion 191 of the locking block 114 can fall downward into the slider locking groove 181, and the pendulum block 117 swings downward as the locking block 114 moves downward.

[0063] Figure 3A-Figure 3ESchematic diagram showing the first embodiment of the door lock device of the present application moving from the door open position to the door closed position and from the door closed position to the door open position. Figure 3A This is a schematic diagram of the first embodiment of the door lock device of the present application in the door open position; Figure 3B This is a schematic diagram of the first embodiment of the door lock device of the present application in the power-assisted door closing stage; Figure 3C This is a schematic diagram of the first embodiment of the door lock device of the present application in the door closing position; Figure 3D This is a schematic diagram of the first embodiment of the door lock device of the present application in the door pulling stage; Figure 3E This is a schematic diagram of the first embodiment of the door lock device of the present application in the door unlocking stage.

[0064] like Figure 3A As shown, in the first embodiment of the door lock device, at the door open position (first position), under the biasing force of the first biasing device 193, the swing block abutting portion 194 of the lock block 114 abuts rightward against the transverse abutting wall 204 of the swing block 117 (see Figure 3A The enlarged view A1 in the upper right corner shows that the locking block 114 is blocked by the pendulum block 117 and cannot move to the right. In addition, the locking portion 191 of the locking block 114 abuts against the slider abutment surface 242 of the slider 112, as shown in FIG. Figure 3A Enlarged view B1 in the lower right corner. If a thrust P is applied to the door of the electrical appliance, causing the striker 101 on the door to push the slider 112 rightward and insert between the pair of locking arms 116, the inserted striker 101 can be wrapped or engaged by the pair of locking arms 116, allowing the locking arms 116 and the connected slider 112 to move rightward relative to the lock block 114 together with the striker 101.

[0065] like Figure 3B As shown, when the slider 112 slides rightward to a position (third position) where the slider locking groove 181 is aligned with the locking portion 191 of the locking block 114, the locking portion 191 of the locking block 114 can fall into the slider locking groove 181. Figure 3B In addition, the swing block abutment portion 194 of the lock block 114 is separated from the abutment with the transverse abutment wall 204 of the swing block 117 and moves to the lower side of the longitudinal abutment wall 206 (see Figure 3B The enlarged view A2 in the upper right corner shows that the locking block 114 can move to the right under the biasing force of the first biasing device 193, and the door locking device thus enters the power-assisted door closing stage.

[0066] like Figure 3C As shown, the locking block 114 is biased by the first biasing device 193 through the mutual contact between the locking portion 191 and the slider locking groove 181 (see Figure 3CThe enlarged view B3 in the lower right corner) allows the locking portion 191 to apply a first directional biasing force to the slider 112, so that the locking block 114 can drive the slider 112 to move rightward until the pendulum block abutting portion 194 abuts rightward against the longitudinal inner contour 302 below the longitudinal abutting wall 206 of the pendulum block 117 (see FIG. Figure 3C In the enlarged view A3 in the upper right corner, the door lock device reaches the door closing position (second position).

[0067] from Figures 3A-3C It can be seen that when the door of the electrical equipment is closed, the door lock device Figures 3A-3B The door lock device moves to the state of continuously applying a thrust P to the door. Figure 3B In the above process, the rightward movement of the slider 112 reduces the opening of the locking arm 116, thereby wrapping or engaging the striker 101 between the upper locking arm 141 and the lower locking arm 142 of the locking arm 116. Figure 3B In the state shown, the door lock device can drive the slider 112 and the lock block 114 to move rightward under the combined biasing force applied by the first biasing device 193 and the second biasing device (slider torsion spring 183 and slider compression spring 184) to the lock block 114 and the slider 112, thereby driving the striker 101 to move rightward together, and finally closing the door. The above-mentioned movement mechanism of the door lock device allows the door to be opened and closed under the condition of the first direction biasing force. Figure 3B The status shown moves to Figure 3C The state shown not only saves the user the effort of continuously pushing the door, but also gives the user the feeling that the door is sucked into the door lock device when pushing the door to the critical position of closing the door. This suction feeling can enhance the user's experience of using electrical equipment.

[0068] like Figure 3C As shown in the figure, if you want to open the door of the electrical equipment from the closed position, you need to continuously apply a pulling force F in the opening direction (i.e., to the left in the figure) to the door. Under the action of the pulling force F, the striker 101 drives the upper locking arm 141 and the lower locking arm 142 of the locking arm 116 to move leftward, thereby driving the slider 112 to move leftward. When the slider 112 is in a state of mutual contact and locking with the lock block 114, the slider 112 can drive the lock block 114 to move leftward together, and the door lock device enters the locked state. Figure 3D The sliding door stage is shown.

[0069] like Figure 3D As shown, under the continuous action of the pulling force F, the locking block 114 continues to move to the left, and the abutting portion 194 of the locking block 114 is disengaged from the longitudinal abutting wall 206 and the longitudinal inner contour 302 of the pendulum block 117 (see Figure 3D In the enlarged view A4 in the upper right corner, the second guide wall 236 of the locking block 114 moves leftward until it abuts against the guide pin 224. Figure 3D Enlarged view of B4 in the lower right corner.

[0070] like Figure 3E As shown, if the pulling force F is continued to be applied, the door lock device enters the sliding door unlocking stage. Under the mutual abutment between the guide pin 224 and the arc surface of the second guide wall 236, the second guide wall 236 will move upward and leftward relative to the guide pin 224, so that the locking portion 191 of the lock block 114 can swing upward relative to the guide pin 224 (see Figure 3E (Enlarged view B5 in the lower right corner). During the upward swinging of the locking block 114 and its locking portion 191, the limiting groove 232 also moves to the left relative to the limiting pin 222 by a certain amplitude, and the limiting groove 232 rotates to a certain angle relative to the limiting pin 222. The abutting portion 194 of the locking block 114 also moves to the left and swings upward to the left of the transverse abutting wall 204 of the swing block 117 (see FIG. 2 for details). Figure 3E (A5 in the upper right corner). If the locking block 114 is Figure 3E If the pulling force F is continuously applied in the state shown, the locking portion 191 of the locking block 114 can swing upward and move out of the slider locking slot 181, and abut against the slider abutting surface 242 on the right side of the slider locking slot 181 under the action of the biasing force of the first biasing device 193. The abutting portion 194 of the locking block 114 abuts against the left side of the transverse abutting wall 204 of the swing block 117 to overcome the biasing force of the first biasing device 193. After the locking portion 191 of the locking block 114 swings upward and out of the slider locking slot 181, the locking block 114 unlocks the slider 112, so that the slider 112 can continue to move leftward under the action of the pulling force F, thereby gradually increasing the opening of the locking arm 116. When the slider 112 moves leftward to a position close to the slider locking slot 181, the locking portion 191 of the locking block 114 can swing upward and out of the slider locking slot 181, thereby gradually increasing the opening of the locking arm 116. Figure 3A In this position, the upper locking arm 141 and the lower locking arm 142 of the locking arm 116 can release the wrapping or engagement of the striker 101, thereby allowing the door to be opened and the door locking device completes the movement from the closed position to the open position.

[0071] Figures 4A-4C The diagram shows a second embodiment of the door lock device of the present application moving from a door closing position to a door opening position. Figure 4A This is a schematic diagram of the second embodiment of the door lock device of the present application in the door closing position; Figure 4B This is a schematic diagram of the second embodiment of the door lock device of the present application in the unlocking critical position; Figure 4C This is a schematic diagram of the second embodiment of the door lock device of the present application in the unlocked position.

[0072] like Figure 4AAs shown, the difference between the second embodiment of the door lock device of the present application and the first embodiment is that the door lock device is further provided with an electromagnetic unlocking device 120 and a control device 160 in communication with the electromagnetic unlocking device 120. In the closed position, the relative positions of the swing block abutment portion 194 and the swing block 117, and the relative positions of the lock block 114 and the slider 112 in the second embodiment of the door lock device are the same as those in the first embodiment. Figure 3C The position of the first embodiment of the door lock device is the same as shown, see Figure 4A The enlarged view C1 in the upper right corner and Figure 4A The enlarged view D1 in the lower right corner will not be described in detail here.

[0073] like Figures 4A-4B As shown, in the closed door position, when it is necessary to unlock and open the door, the control device 160 controls the electromagnetic pulse generating device 122 to transmit an electromagnetic pulse signal to the lock block actuating rod 121, and the lock block actuating rod 121 can move upward once to drive the lock block 114 to swing upward, so that the swing block abutting portion 194 of the lock block 114 swings upward to a position where it abuts against the longitudinal abutting wall 206 of the swing block 117, and drives the longitudinal abutting wall 206 of the swing block 117 to swing upward together, until the swing block 117 swings to abut against the longitudinal cross block 212 of the swing block chute 134, see for details. Figure 4B The enlarged view C2 in the upper right corner. The locking portion 191 of the locking block 114 also swings upward with the locking block 114 to release the lock of the slider 112, see Figure 4B The enlarged view D2 in the lower right corner shows that the door lock device is at the unlocking critical position. The slider 112 loses the locking of the lock block 114 and can be ejected to the left under the biasing force of the second biasing device, thereby opening the door of the electrical device.

[0074] like Figure 4C As shown, when the electromagnetic pulse signal disappears, the locking block 114 tends to move downward under the biasing force of the first biasing device 193. Since the slider 112 slides to the left at this time to the position where the slider locking groove 181 is not aligned with the locking portion 191 of the locking block 114 (unlocked position), the locking portion 191 of the locking block 114 can be downwardly abutted against the slider abutting surface 242 on the right side of the slider locking groove 181. Figure 4CEnlarged view D3 in the lower right corner. The pendulum block 117 has a tendency to swing downward under the biasing force of the pendulum block torsion spring (not shown in the figure), so the pendulum block 117 and the longitudinal cross-bar 212 of the pendulum block slot 134 no longer abut each other, and the longitudinal abutting wall 206 of the pendulum block 117 abuts downward against the pendulum block abutting portion 194 of the lock block 114. Since the pendulum block abutting portion 194 of the lock block 114 only swings upward and does not move to the left during the door opening stage, the pendulum block abutting portion 194 still abuts to the right against the longitudinal inner contour 302 below the longitudinal abutting wall 206 of the pendulum block 117 under the biasing force of the first biasing device 193, see for details. Figure 4C Zoomed view of C3 in the upper right corner.

[0075] If in Figure 4C To close the door again in the state shown, it is only necessary to apply a continuous thrust P to the door again so that the slider 112 slides to the right to a position where the slider locking groove 181 is aligned with the locking portion 191 of the lock block 114, so that the locking portion 191 of the lock block 114 can swing downward into the slider locking groove 181 under the action of the biasing force of the first biasing device 193, thereby locking the slider 112 and closing and locking the door.
