[0051] Figures 1A-1F Schematic diagram of the door lock assembly 100 of the present application observed from various angles. Figure 1A A three-dimensional view of the door lock assembly of the present application, wherein the door hook is in an uninserted state; Figure 1B Hidden Figure 1AThe housing 102 in the figure is shown to show more components inside the housing 102; Figure 1C for Figure 1B A perspective view of the door lock assembly after the door hook is inserted; Figure 1D A three-dimensional diagram of the door lock assembly of the present application from a bottom perspective; Figure 1E Hidden Figure 1D The other parts except the housing, the pin and the rotating wheel are shown in order to more clearly show the assembly relationship between the pin and the housing and the matching relationship between the pin and the rotating wheel; Figure 1F An exploded view of the door lock assembly for this application.

[0052] like Figures 1A-1C As shown, the door lock assembly 100 includes a housing 102 and a moving component 104 and a rotating wheel 108 accommodated in the housing 102. The moving component 104 may be a rotating wheel seat 104, which may be accommodated in the housing 102 and reciprocate relative to the housing 102 along the Z direction. The rotating wheel seat 104 has an upper limit position and a lower limit position in its reciprocating movement. The upper limit position of the rotating wheel seat 104 corresponds to the open position or the unclosed position of the door, and the lower limit position of the rotating wheel seat 104 corresponds to the closed position of the door. Figure 1A As shown, a door hook hole 182 is provided on the upper surface of the housing 102 for accommodating the door hook 101 installed on the door of the electrical device. When the door hook 101 passes through the door hook hole 182 on the housing 102 and is inserted into the interior of the housing 102, the door hook 101 can be engaged with the rotating wheel 108 inside the door lock assembly 100. When the door hook 101 is locked by the rotating wheel 108, the door of the electrical device is also locked.

[0053] The door hook 101 includes a door hook base 122 and a door hook striker 123. The door hook base 122 is installed on the door of the electrical equipment. The end of the door hook striker 123 is provided with a door hook hole 124 and a door hook head 126. The door hook head 126 is the lower side wall of the door hook hole 124 and has an inner side surface 128 of the door hook head. When the door hook 101 is inserted into the housing 102, the door hook head 126 can push the rotating wheel 108 to rotate around the rotating wheel shaft 308 (see Figure 3 The rotating wheel shaft 308 in the door hook 101 rotates, and the rotating wheel 108 can be engaged with the door hook hole 124 during the rotation process. When the door hook 101 is pulled out from the inside of the housing 102, the inner side surface 128 of the door hook head can pull the rotating wheel 108 to rotate in the opposite direction, and the rotating wheel 108 and the door hook hole 124 are gradually disengaged. When the door is in a closed state, the main body of the door hook striker 123 remains inside the housing 102, and the door hook hole 124 of the door hook 101 is hooked and locked by the rotating wheel 108, so that the door hook 101 and the door are locked and cannot move.

[0054] like Figure 1B-1CAs shown, the rotating wheel 108 is rotatably mounted on the rotating wheel seat 104 so that the rotating wheel 108 can swing back and forth in the rotating wheel seat 104. Specifically, the rotating wheel seat 104 is provided with rotating wheel receiving parts 152, 153 for mounting the rotating wheel shaft 308 of the rotating wheel 108, so that the rotating wheel 108 can be fixed on the rotating wheel seat 104 and can rotate relative to the rotating wheel seat 104. The extending direction of the rotating wheel shaft 308 of the rotating wheel 108 is perpendicular or substantially perpendicular to the direction of the reciprocating movement of the rotating wheel seat 104. The rotating wheel 108 has an upper swing limit position and a lower swing limit position within its swing range, the upper swing limit position of the rotating wheel 108 corresponds to the upper movement limit position of the rotating wheel seat 104 and the open position or unclosed position of the door, and the lower swing limit position of the rotating wheel 108 corresponds to the lower movement limit position of the rotating wheel seat 104 and the closed position of the door.

[0055] Continue to refer to Figure 1B-1C The door lock assembly 100 further includes two bias springs 110, 111 disposed on the rotary wheel seat 104. A barrel-shaped bias spring cavity 132, 134 is provided on the left and right sides of the rotary wheel seat 104 along the X direction, and each of the bias spring cavities 132, 134 is used to accommodate a bias spring. The inner diameter of the bias spring cavity 132, 134 is slightly larger than the outer diameter of the bias spring 110, 111, so that the bias spring does not generate bending deformation deviating from the compression direction when compressed in the barrel-shaped cavity. One end of each bias spring abuts against the bottom of the bias spring cavity 132, 134, and the other end abuts against the inner surface of the upper wall of the housing 102. When the wheel seat 104 moves toward the housing 102 along the Z direction, the bias springs 110, 111 are compressed, so that the bias springs 110, 111 can apply a bias force to the wheel seat 104 in the opposite direction of the movement of the wheel seat 104, so that the wheel seat 104 has a tendency to move away from the housing 102. In the embodiment of the present application, during the door opening process, the wheel seat 104 moves toward the housing 102, and the bias spring is gradually compressed, thereby storing elastic potential energy; during the door closing process, the wheel seat 104 moves away from the housing 102, and the bias spring gradually rebounds from the compressed state to the initial state.

[0056] For ordinary technicians in this field, only one barrel-shaped cavity may be set on the wheel seat 104, and the corresponding door lock assembly 100 only includes one bias spring, or more than two barrel-shaped cavities may be set on the wheel seat 104, and each barrel-shaped cavity is used to accommodate a bias spring, as long as the wheel seat 104 can be subjected to the bias force of the bias spring when moving close to the shell 102 along the Z direction.

[0057] Continue to refer to Figure 1B-1CThe door lock assembly 100 further includes a door state signal assembly 114, which is arranged close to the X direction of the rotary seat 104, that is, the door state signal assembly 114 is arranged on one side of the rotary seat 104 along the length direction, and is used to generate a door state indication signal to indicate the position of the door. The door state signal assembly 114 has a trigger switch or micro switch 212 (see Figures 2A-2F During the door closing process, the trigger switch 212 of the door state signal component 114 and the trigger structure of the rotating wheel seat 104 (see Figures 2A-2F ) gradually disconnects the contact, and during the door opening process, the trigger switch 212 of the door status signal component 114 can be triggered by the trigger structure of the wheel seat 104.

[0058] Figure 1D This is a three-dimensional view of the door lock assembly 100 of the present application from a bottom perspective. Figure 1E Hidden Figure 1D The other components except the housing 102, the pin 112 and the rotating wheel 108 are shown in the figure to more clearly illustrate the assembly relationship between the pin 112 and the housing 102 and the matching relationship between the pin 112 and the rotating wheel 108.

[0059] like Figure 1D As shown, the door lock assembly 100 also includes a pin 112. The housing 102 has two left and right pin mounting portions 144 and 146 protruding in the negative direction of the Z direction. Each pin mounting portion 144 and 146 has a corresponding pin mounting hole 145 and 147 for fixing and mounting the pin 112, so that the installed pin 112 extends along the length direction (X direction) of the rotary wheel seat 104. The housing 102 has a door state signal assembly accommodating portion 142 for accommodating and mounting the door state signal assembly 114, so that the door state signal assembly 114 can be fixedly mounted on the housing 102.

[0060] Continue as Figure 1D As shown, the bias spring cavities 132, 134 of the wheel seat 104 have cavity abutment walls 133, 135 (the figure shows the outer side of the cavity bottom abutment wall, Figure 2B and 2E The housing 102 is also shown in the figure, so that one end of the bias spring 110, 111 accommodated in the bias spring cavity 132, 134 can abut against the cavity abutment wall 133, 135. The inner side of the housing 102 is also provided with a bias spring abutment surface 162, 164 (see Figure 2B and 2E), so that the other end of the bias spring 110, 111 relative to the bias spring cavity 132, 134 can abut on the bias spring abutment surface 162, 164. Therefore, the bias spring 110, 111 is confined and compressed between the cavity abutment walls 133, 135 of the rotating wheel seat 104 and the bias spring abutment surfaces 162, 164 of the housing 102 that are arranged opposite to each other. The cavity walls of the bias spring cavities 132, 134 can limit the bending deformation of the bias spring 110, 111 that deviates from the compression direction, so that the bias spring 110, 111 can generate a rebound force proportional to the compression displacement during the compression process, and the rebound force acts on the cavity abutment walls 133, 135 of the bias spring cavities 132, 134, thereby generating a bias force on the rotating wheel seat 104 and the rotating wheel 108. Since the bias spring generates a stable bias force, the movement of the wheel seat 104 and the wheel 108 inside the housing 102 is smoother than that of the wheels in the prior art, making the overall feel of the door opening and closing action smoother.

[0061] like Figure 1E As shown, the pin 112 is kept in contact with the cam surface of the rotating wheel 108, and the pin 112 and the rotating wheel 108 can always be kept in contact under the action of the bias springs 110, 111. Since the cam surface of the rotating wheel 108 has different rotation radii, the rotating wheel 108 can be relatively abutted with the pin 112 at different rotation radii through the cam surface when rotating, so that the rotating wheel 108 together with the rotating wheel shaft 308 moves relative to the pin 112. As described above, the rotating shaft of the rotating wheel 108 is fixedly mounted on the rotating wheel seat 104, so that the movement of the rotating wheel 108 can also make the rotating wheel seat 104 move relative to the pin 112 with the rotating wheel 108. Since the rotating wheel seat 104 is limited to move along the Z direction of the housing 102, the rotating wheel 108 can make the rotating wheel seat 104 reciprocate along the Z direction relative to the housing 102 when the rotating wheel 108 reciprocates and rotates.

[0062] Figure 1F This is an exploded view of the door lock assembly of the present application, to illustrate the installation relationship and position relationship of the various components in the door lock assembly 100.

[0063] like Figure 1FAs shown, the door hook 101 installed on the door of the electrical device can be inserted into the housing 102 through the door hook hole 182 on the upper surface of the housing 102, so as to be engaged with the rotating wheel 108 arranged inside the housing 102. The door hook 101 can hit the rotating wheel 108 in the process of inserting into the housing 102, so that it swings downward, and the door hook 101 can pull the rotating wheel 108 in the process of pulling out of the housing 102, so that it swings upward. The rotating wheel 108 is rotatably mounted on the rotating wheel seat 104 arranged inside the housing 102 through the rotating wheel shaft 308, so that the rotating wheel 108 can swing back and forth in the rotating wheel seat 104, but the rotating wheel 108 cannot move relative to the rotating wheel seat 104 except for rotation. In the process of the rotating wheel seat 104 moving relative to the housing 102 along the Z direction, the rotating wheel 108 and the rotating wheel seat 104 can move relative to the housing 102 along the Z direction at the same time. During the movement of the rotary wheel seat 104 relative to the housing 102, the door state signal component 114, which is also arranged inside the housing 102, can be actuated by the trigger structure, so that the door state signal component 114 is turned on or off, thereby generating different door state indication signals. The two bias springs 110, 111 are accommodated in the bias spring cavities 132, 134 of the rotary wheel seat 104 and abut upward against the inside of the housing 102. Therefore, the bias springs 110, 111 make the rotary wheel seat 104 have a tendency to move away from the housing 102, that is, a tendency to move downward in the negative direction of the Z direction relative to the housing 102. Since the rotary wheel 108 installed on the rotary wheel seat 104 is relative to the cam surface on one side of the door hook 101 (see Figure 3 ) is arranged on the upper side of the pin shaft 112, so under the action of the biasing force of the biasing springs 110, 111, the cam surface of the rotating wheel 108 and the pin shaft 112 can always be kept in abutment.

[0064] Figure 2A-2F Schematic diagrams of the door lock assembly at other viewing angles are shown to illustrate the matching relationship between the trigger structure of the rotary seat 104 and the door state signal assembly 114. Figure 2A This is a side view of the door lock assembly of this application in an unclosed state. Figure 2B for Figure 2A The cross-sectional view obtained along the cutting line AA, Figure 2C for Figure 2B A partial enlarged view of B; Figure 2D This is a side view of the door lock assembly in the closed state of this application. Figure 2E for Figure 2D The cross-sectional view obtained along the cutting line CC, Figure 2F for Figure 2E A partial enlarged view of D.

[0065] like Figures 2A-2F As shown, the wheel seat 104 has one side along the length direction ( Figure 2BThe door state signal component 114 is installed and arranged on the side 201 of the rotary wheel seat 104 along the length direction toward the rotary wheel seat 104, and includes a trigger switch 212. The trigger switch 212 has a switch protrusion structure 214 arranged toward the step structure. The switch protrusion structure 214 is in an extended position when not subjected to force, and is moved to a retracted position once subjected to a squeeze force.

[0066] During the reciprocating movement of the wheel seat 104 along the Z direction, when the step protrusion 204 of the step structure moves to a position where it overlaps with the switch protrusion structure 214 of the trigger switch 212 (see Figure 2C ), the step protrusion 204 contacts and squeezes the switch protrusion structure 214, and makes the switch protrusion structure 214 in the retracted position, so that the door state signal component 114 generates the first state signal of the door; when the step retracted portion 206 of the step structure moves to the overlapped position with the switch protrusion structure 214 of the trigger switch 212 (see Figure 2F ), the step protrusion 204 is disengaged from the switch protrusion structure 214, no longer squeezing the switch protrusion structure 214, and the switch protrusion structure 214 is in an extended position, so that the door state signal component 114 generates a second state signal of the door.

[0067] More specifically, when the door hook 101 is not inserted into or has just been inserted into the door hook hole 182 of the housing 102, the wheel seat 104 is in an upper position in the housing 102, and the step protrusion 204 and the switch protrusion structure 214 are in a coincident position (see Figure 2B-2C ), the switch protrusion structure 214 is squeezed to the retracted position, and the door state signal component 114 generates a door unclosed state signal (first state signal); when the door hook 101 is inserted from the door hook hole 182 into the housing 102 to a certain depth, as the door hook hole 182 is inserted and moves downward, the step retracted portion 206 above the step protrusion 204 moves to a position where it overlaps with the switch protrusion structure 214 (see Figure 2E-2F ), the step protrusion 204 moves to no longer contact with the switch protrusion structure 214, the switch protrusion structure 214 is released, and thus returns to the extended position, and the door state signal component 114 generates a closed state signal (a second state signal) of the door.

[0068] In the embodiment of the present application, the door state signal assembly 114 further includes a circuit board 222, which is fixedly mounted on the door lock assembly 100. The trigger switch 212 is mounted on the circuit board 222, and the switch protrusion structure 214 of the trigger switch 212 extends out of the circuit board 222 toward the trigger structure 202 of the rotary seat 104. The circuit board 222 is provided with a circuit (not shown in the figure) for generating a door closed state signal and a door open state signal.

[0069] For ordinary technicians in this field, the upper and lower position relationship between the step protrusion 204 and the step retracted portion 206 can also be adjusted, and by changing the circuit settings, the door status signal component 114 can generate a door closed status signal when the switch protrusion structure 214 is squeezed to the retracted position, and the door status signal component 114 can generate a door open status signal when the switch protrusion structure 214 is released to the extended position, as long as the door status signal component 114 can generate corresponding door status signals at different moving positions of the wheel seat 104.

[0070] Figure 3 It is a side view of the rotating wheel 108 to illustrate the specific structure of the rotating wheel 108 .

[0071] like Figure 3 As shown, the rotating wheel 108 includes a rotating wheel hook 322 located at the rotating wheel head, a rotating wheel middle part 324 and a rotating wheel tail part 326. The rotating wheel middle part 324 is provided with a rotating wheel shaft 308. The rotating wheel hook 322 is provided with a lower locking hook 302, an upper locking hook 304 and a locking hook cavity 306. When the door hook 101 is inserted into the housing 102, the door hook head 126 of the door hook 101 can hit the lower locking hook 302 of the rotating wheel 108, so that the rotating wheel 108 moves downward ( Figure 3 In the process of pulling out the door hook 101 from the housing 102, the inner side surface 128 of the door hook head of the door hook 101 can pull the locking hook 304 of the rotating wheel 108 upward ( Figure 3 when the door is in a closed state, the door hook 101 remains inside the door lock assembly 100, and the door hook hole 124 of the door hook 101 is confined in the lock hook cavity 306 of the rotating wheel 108, so that the door hook 101 is locked and cannot move.

[0072] The wheel tail 326 has a cam structure, and the outer edge of the cam structure has different rotation radii. The cam structure can abut against the pin 112, so that when the wheel 108 swings back and forth in the wheel seat 104, the wheel 108 can reciprocate relative to the pin 112 inside the housing 102, and drive the wheel seat 104 to reciprocate. During the reciprocating movement of the wheel seat 104 inside the housing 102, the bias springs 110, 111 are compressed or rebounded in the bias spring cavities 132, 134 of the wheel seat 104, thereby applying or releasing a bias force to the wheel seat 104.

[0073] Continue to refer to Figure 3 The cam structure of the rotating wheel 108 is provided with inner side surfaces 312, 314 and outer side surfaces 316. The inner side surface includes a circular groove 312 and an ascending slope 314, and the outer side surface 316 is a descending slope 316. The circular groove 312 and the ascending slope 314 intersect and connect at point A, and the ascending slope 314 and the descending slope 316 intersect and connect at point B. The inner diameter of the circular groove 312 is substantially the same as the outer diameter of the pin 112, so that the pin 112 can be just engaged in the circular groove 312. The position where the pin 112 is engaged in the circular groove 312 corresponds to the limit position of the rotating wheel 108 swinging downward, that is, the stable position of the door in the closed state. When the door is opened from the closed position, the door hook 101 pulls the rotating wheel 108 upward. When the rotating wheel 108 has a tendency to swing upward, the force point of the pin 112 abutting against the circular groove 312 occurs at point O of the circular groove 312. When the door is opened, the rotating wheel 108 swings upward to the extreme position, and the pin 112 abuts against the descending slope 316 of the rotating wheel 108 , that is, the rotating wheel 108 is in a stable position when the door is in the open state.

[0074] In the absence of external force, if the rotating wheel 108 abuts against the pin shaft 112 on the descending slope 316, the abutting force generated by the abutment of the rotating wheel 108 at the abutting position points to the center of the rotating wheel shaft 308 of the rotating wheel 108, and no torque is generated on the rotating wheel 108. At the same time, the abutting force can offset the biasing force applied to the rotating wheel 108 and the rotating wheel seat 104 by the biasing springs 110, 111, so that the rotating wheel 108 and the rotating wheel seat 104 remain stationary relative to the housing 102 without moving; if the rotating wheel 108 abuts against the pin shaft 112 on the circular groove 312 or the ascending slope 314, the abutting force generated by the abutment of the rotating wheel 108 at the abutting position points to the left side of the center of the rotating wheel shaft 308 of the rotating wheel 108, and the abutting force will bring a torque to the rotating wheel 108 to swing downward, so the abutting force can make the rotating wheel 108 swing downward. Once the rotating wheel 108 swings, the contact between the rotating wheel 108 and the pin shaft 112 allows the rotating wheel 108 and the rotating wheel seat 104 to move in the negative direction of the Z direction relative to the shell 102 under the action of the contact force, and finally the rotating wheel 108 drives the door hook 101 to pull the door to the closed position.

[0075] For the convenience of description, the descending slope 316 of the runner 108 is referred to as the runner holding side, and the circular groove 312 or the ascending slope 314 of the runner 108 is referred to as the runner abutting side.

[0076] Figure 4A-Figure 8 The figure shows the movement of the internal components of the door lock assembly 100 during the process of closing and opening the door, and also shows the different triggering states of the door state signal assembly 114. For the sake of easy observation, only the door hook striker 123 of the door hook 101 is shown in the figure, and the door hook base 122 is omitted. Figure 4A This is the internal side view when the door hook is inserted into the door hook hole and just contacts the rotating wheel. Figure 4B for Figure 4A An internal view of the door hook in an inserted state from another perspective; Figure 5A It is an internal side view of the door hook being inserted into the door hook hole to a first depth, Figure 5B for Figure 5A An internal view of the door hook in an inserted state from another perspective; Fig. 6A The internal side view of the door hook being inserted into the door hook hole to the second depth, Figure 6B for Fig. 6A An internal view of the door hook in an inserted state from another perspective; Fig. 7A This is an internal side view of the door hook fully inserted into the door hook hole. Figure 7B for Fig. 7A An internal view of the door hook in an inserted state from another perspective; Figure 8 Interior side view of the door hook hole with the door hook fully removed.

[0077] like Figure 4A-4B As shown, the door hook 101 passes downward through the door hook hole 182, the door hook head 126 just contacts and pushes the lower lock hook 302 of the rotating wheel 108, the rotating wheel 108 has a tendency to swing downward, and the upper lock hook 304 of the rotating wheel 108 has a tendency to move into the door hook hole 124. The step protrusion 204 of the rotating wheel seat 104 is in a coincident position with the switch protrusion structure 214 of the trigger switch 212, the switch protrusion structure 214 is squeezed to the retracted position, and the door state signal component 114 generates a door unclosed state signal. At this time, the rotating wheel holding side 316 of the rotating wheel 108 abuts against the pin shaft 112, and the abutment force generated can counteract the biasing force applied to the rotating wheel 108 and the rotating wheel seat 104 by the bias springs 110, 111, and the downward insertion force of the door hook 101 provides the torque for the rotating wheel 108 to rotate and the power for closing the door.

[0078] like Figure 5A-5BAs shown, as the door hook 101 is further inserted downward into the door hook hole 182, the door hook head 126 continues to push the lower lock hook 302 of the rotating wheel 108 downward to make the rotating wheel 108 swing downward, and the upper lock hook 304 of the rotating wheel 108 extends into the door hook hole 124, thereby engaging with the door hook 101. The step protrusion 204 of the rotating wheel seat 104 and the switch protrusion structure 214 of the trigger switch 212 are still in the overlapping position, the switch protrusion structure 214 is squeezed to the retracted position, and the door state signal component 114 generates a door unclosed state signal. Due to the downward swing of the rotating wheel 108, the position where it abuts against the pin shaft 112 gradually transitions from the rotating wheel holding side 316 to the rotating wheel abutting side 314, and the generated abutting force can still resist the biasing force applied to the rotating wheel 108 and the rotating wheel seat 104 by the bias springs 110, 111. At this time, the downward insertion force of the door hook 101 provides the torque for the rotating wheel 108 to rotate and the power for closing the door.

[0079] like Figure 6A-6B As shown, as the door hook 101 is further inserted downward into the door hook hole 182, the door hook head 126 continues to push the lower lock hook 302 of the rotating wheel 108 downward to make the rotating wheel 108 swing downward. The upper lock hook 304 of the rotating wheel 108 remains in the door hook hole 124 and is engaged with the door hook 101. The step retracted portion 206 of the rotating wheel seat 104 moves to a position where it overlaps with the switch protrusion structure 214, and the step protrusion 204 moves to no longer contact the switch protrusion structure 214, and the switch protrusion structure 214 is released and returns to the extended position, and the door state signal component 114 generates a closed state signal of the door. As the rotating wheel 108 swings downward, the position where it abuts against the pin shaft 112 transitions from the rotating wheel holding side 316 to the rotating wheel abutting side 314, and the abutting force generated cannot continue to resist the biasing force applied to the rotating wheel 108 and the rotating wheel seat 104 by the biasing springs 110, 111. Therefore, the biasing force applied to the rotating wheel 108 and the rotating wheel seat 104 by the biasing springs 110, 111 can push the rotating wheel seat 104 to drive the rotating wheel 108 to move downward, prompting the rotating wheel 108 to swing further downward, thereby pulling the door hook 101 to move downward. At this time, in the absence of external force, the rotating wheel 108 and the rotating wheel seat 104 will continue to move downward under the biasing force of the biasing springs 110, 111.

[0080] See also Figure 7A-7BWhen the rotating wheel 108 swings downward to the lower swing limit position (i.e. the pin 112 abuts against the circular groove 312 on the abutting side of the rotating wheel), the rotating wheel seat 104 moves to the lower movement limit position, and the door hook 101 is inserted downward to the maximum depth, i.e. the position of being fully inserted into the door hook hole 182. The step retracted portion 206 of the rotating wheel seat 104 remains in a coincident position with the switch protrusion structure 214, the switch protrusion structure 214 remains in an extended position, and the door state signal component 114 continues to generate a closed state signal of the door. At this time, the door is in a fully closed state, and the locking hook 304 of the rotating wheel 108 remains in the door hook hole 124 and is engaged with the door hook 101. Under the action of the biasing force of the biasing springs 110, 111, as long as there is no external force to resist the biasing force, the door will always remain in a fully closed state and be locked.

[0081] See also Figure 8 If the door needs to be opened from the closed state, a continuous upward pulling force F needs to be applied to the door, so that the door hook head 126 of the door hook 101 pulls the locking hook 304 of the rotating wheel 108 to make the rotating wheel 108 swing upward. During the upward swinging of the rotating wheel 108, the locking hook 304 of the rotating wheel 108 gradually withdraws from the door hook hole 124 and disengages from the door hook 101, and the position where the rotating wheel 108 abuts against the pin 112 gradually transitions from the rotating wheel abutting side 314 to the rotating wheel holding side 316. When the door hook 101 is completely disengaged from the locking hook 304 of the rotary wheel 108, the rotary wheel seat 104 moves to the upper movement limit position, and the rotary wheel 108 swings upward to the upper swing limit position. At this position, the rotary wheel retaining side 316 abuts against the pin shaft 112, and the abutment force generated can counteract the biasing force applied to the rotary wheel 108 and the rotary wheel seat 104 by the biasing springs 110 and 111. Therefore, the rotary wheel 108 will remain in the position when it is separated from the door hook 101 without any movement or swinging, until the door hook 101 is inserted again to actuate the rotary wheel 108 to move downward and swing.

[0082] Fig. 9 It is a schematic diagram of an electrical device 900 having a door lock assembly 100 of the present application in a door open position.

[0083] like Fig. 9 As shown, the electrical device 900 may be a dryer, which has a dryer body 902, a door 904, a cavity 906, and a door lock assembly 100, wherein a door hook 101 is disposed on the inner side of the door 904, and the door lock assembly 100 is disposed on the dryer body 902 at a position corresponding to the door hook 101. By closing the door 904, the door hook 101 can pass through the door hook hole 182 and engage with the rotating wheel 108 inside the door lock assembly 100, thereby locking the door 904 through the movement process described above.

[0084] Fig. 9The dryer shown is only an example, and the door lock assembly of the present application can also be installed on various electrical devices having a cavity and a door for closing the cavity, such as a washing machine, a dishwasher, a microwave oven, etc., and can also be installed on other non-electrical devices.

[0085] The purpose of this application is to at least partially solve the technical problems mentioned herein.

[0086] The door lock assembly of the present application can at least achieve the following beneficial technical effects:

[0087] First, in the door lock assembly of the present application, the door status signal assembly is arranged on the side facing the length direction of the rotary wheel seat, so that the width or thickness direction of the door lock assembly is smaller, and the door lock assembly can be manufactured more compactly.

[0088] Second, since the door lock assembly of the present application is thinner in the thickness direction, when installed on an electrical device, the door lock assembly can be installed interchangeably in the left and right directions, and the door lock assembly can be installed from the front side of the electrical device without disassembling the electrical device.

[0089] Third, the door lock assembly of the present application adopts a door status signal assembly with a circuit board, and the trigger switch or micro switch is directly connected to the circuit board, which reduces the overall size of the door status signal assembly and makes the structure of the door lock assembly more compact; and avoids the use of reed switches to generate door status signals, thereby lowering manufacturing costs.
