[0054] like Figures 1 to 5 As shown, this embodiment provides an electrical appliance comprising a body 300 and a door 400. The body 300 is provided with an inner container 301 with a front opening. The door 400 is movably mounted on the front side of the body 300 and can open or close the front opening of the inner container 301. The appliance further comprises a door lock device 100 and a lock component 200. The door lock device 100 is mounted on the body 300, and the lock component 200 is mounted on the door 400. When the door 400 closes the front opening of the inner container 301, the door lock device 100 cooperates with the lock component 200 to securely lock the door 400 and the body 300, thereby ensuring the reliability of the appliance.

[0055] It is worth noting that the electrical appliance can be a cooking device such as a steamer, an oven, or a steam-bake combination machine, or it can be other types of electrical appliances such as a dishwasher. The utility model does not limit the type of electrical appliance.

[0056] In this embodiment, the lower end of the door 400 is hingedly connected to the body 300 via a hinge mechanism 700. That is, the upper end of the door 400 can be tilted outward relative to the body 300 to open the front opening of the inner container 301. When closing the door, the upper end of the door 400 tilts toward the body 300 to close the door 400 relative to the body 300. Specifically, in this embodiment, the lock component 200 is disposed at the top of the door 400, and the door lock device 100 is mounted on the top outer side of the inner container 301.

[0057] In other embodiments, the machine door 400 can be hinged to the machine body 300 on one side or the other. In this setting, the lock component 200 is installed on the side of the machine door 400 away from its rotation axis, and the installation position of the door lock device 100 is specifically set according to the position of the lock component 200.

[0058] In this embodiment, when the appliance door 400 is closed, the hinge mechanism 700 applies an elastic force to the appliance door 400, causing the door 400 to flip outward relative to the appliance body 300. Consequently, when the door lock device 100 and the lock component 200 are unlocked, the door 400 automatically flips outward under the elastic force of the hinge mechanism 700, thereby automatically opening the door 400. This improves the convenience of opening the appliance door and enhances the convenience and user experience of the appliance. In other embodiments, the door 400 may only be opened manually by the user.

[0059] Furthermore, when the door 400 is tilted and opened to a predetermined angle relative to the body 300, the hinge mechanism 700 provides damping to the door 400 to prevent it from tilting. This allows the door 400 to slowly rotate downward under the combined effects of gravity and the resistance exerted by the hinge mechanism 700, thereby preventing the door 400 from tilting downward too quickly and potentially colliding with other structures. The specific structure of the hinge mechanism 700 can be configured with reference to existing technologies and is not limited or elaborated upon in this embodiment.

[0060] The housing 300 also includes a casing 302 and a front frame 303. The casing 302 wraps around the outer surface of the inner container 301 and forms the exterior of the housing 300. The front frame 303 surrounds the front of the inner container 301, with its upper end positioned higher than the inner container 301. Both the front of the inner container 301 and the front of the casing 302 are secured to the front frame 303. The door lock device 100 is mounted between the top of the inner container 301 and the top of the casing 302. Specifically, a top support plate 304 is mounted on the top of the casing 302, and the door lock device 100 is mounted above the top support plate 304 to facilitate installation.

[0061] It is understandable that the structures of the casing 302, the inner tank 301, the top support plate 304 and the door 400 and the structure of the hinge mechanism 700 can be specifically configured with reference to the existing technology. This is not the focus of the present invention and will not be described in detail here.

[0062] like Figure 6 、 Figure 7 and Figure 11 As shown, in this embodiment, the door lock device 100 includes an actuating assembly 1, a slide bar 2, and a door lock assembly 3. The actuating assembly 1 includes a drive motor 11 and an actuating member 12. The drive motor 11 drives the actuating member 12 to rotate. The actuating member 12 can selectively push the first end of the slide bar 2 to push the slide bar 2 to move by rotating. The door lock assembly 3 includes a lock base 31 and a door lock unit. The door lock unit is rotatably mounted on the lock base 31 about a first axis. The door lock unit is hingedly connected to or abuts the second end of the slide bar 2 and can rotate relative to the slide bar 2 about a second axis. The second axis is parallel to the first axis and spaced apart. The movement of the slide bar 2 can drive the door lock unit to rotate about the first axis, so that the door lock unit switches between a locked position in which it can cooperate with the lock component 200 and an unlocked position in which it disengages from the lock component 200.

[0063] The door lock device 100 provided in this embodiment has the actuator assembly 1 and the door lock assembly 3 respectively arranged at the two ends of the slide rod 2. When the door lock device 100 is installed on the electrical appliance, the installation position of the actuator assembly 1 and the installation position of the door lock assembly 3 can be separated and the two are transmitted through the slide rod 2. The structure of the door lock device 100 does not need to be concentrated in a small area, which reduces the requirements of the door lock device 100 for the installation position and installation space, and improves the installation flexibility and convenience of the door lock device 100; at the same time, the actuator assembly 1 and the door lock unit are transmitted through the slide rod 2, which can reduce the correlation between the structures of the actuator assembly 1 and the door lock assembly 3, that is, for electrical appliances of different models and sizes, the installation positions of the actuator assembly 1 and the door lock assembly 3 can be set according to the installation position and installation space, and then the size and structure of the slide rod 2 can be set, thereby improving the structural versatility of the actuator assembly 1 and the door lock assembly 3 and reducing the processing and design costs of the door lock device 100.

[0064] In this embodiment, the first axis and the second axis are both arranged vertically, the door lock assembly 3 is installed at the middle position of the top of the inner container 301 in the left-right direction, and the actuator assembly 1 is installed at one side of the top of the inner container 301 in the left-right direction. This arrangement can utilize the front side space at the top of the appliance body 300 to arrange the various parts of the door lock device 100. At the same time, this arrangement ensures that when the actuator assembly 1 pushes the slide bar 2 to slide, the force applied by the actuator assembly 1 to the first end of the slide bar 2 is a force in the left-right direction. When the door 400 is forcibly opened, the lock component 200 applies a force in the front-to-back direction to the door lock unit. This can reduce the transmission of the force forcing the door to open to the slide bar 2 and the actuator assembly 1, reduce the probability of the door 400 being forcibly opened, and improve the safety of the door lock device 100 and the appliance.

[0065] It is understandable that in other embodiments, the arrangement direction of the slide rod 2 and the installation position of the actuator assembly 1 inside the body 300 can be reasonably set according to the type of electrical appliance and the structural layout of the electrical appliance in the space outside the top of the inner tank 301. The present invention does not impose specific restrictions on this.

[0066] The appliance also includes a control panel 500, which is mounted on the top front side of the door 400 via a panel bracket 503. The user can control the operation of the appliance through the control panel 500. Specifically, the control panel 500 includes a control assembly 501 mounted on the panel bracket 503 and a front panel 502 covering the front side of the control assembly 501. The control assembly 501 includes a control panel and control buttons located on the front side of the control panel. The specific structure of the control panel 500 and its mounting structure on the door 400 can be configured with reference to existing technologies. This is not the focus of this utility model and will not be described in detail here.

[0067] like Figures 6 to 8As shown, the control panel 500 is mounted above the door 400 and extends forward from the front side of the inner container 301. In this embodiment, the door lock device 100 is mounted on a panel bracket 503, and the lower end of the door lock unit extends downward from the control panel 500 to cooperate with the lock component 200. By mounting the door lock device 100 on the panel bracket 503, when a user forcibly opens the door, the force applied by the user to the door 400 is transmitted to the door lock device 100 through the cooperation between the lock component 200 and the door lock unit, and then transmitted to the panel bracket 503 through the door lock device 100. Because the panel bracket 503 is fixedly mounted on the machine body 300 and has a strong structural strength, the panel bracket 503 can assist the door lock device 100 in resisting the force of the user forcibly opening the door, thereby effectively preventing the door lock device 100 from being pulled and damaged by the force of the user forcibly opening the door, thereby improving the safety and reliability of the door lock device 100.

[0068] The panel bracket 503 includes a vertically mounted front mounting plate and mounting side panels perpendicularly arranged around the periphery of the front mounting plate. The mounting side panels are connected to the rear side of the front mounting plate. Together, the mounting side panels and the front mounting plate form an installation space. The control assembly 501 is mounted within the installation space. The front mounting plate has an opening for exposing the control components of the control assembly 501. The front panel 502 is mounted on the front side of the front mounting plate. The specific structure of the panel bracket 503 and the connection structure between the panel bracket 503 and the body 300 can be configured with reference to existing structures and are not limited or elaborated on in this utility model.

[0069] The mounting plate connected to the lower edge of the front mounting plate is the lower mounting plate 5031. The door lock device 100 is mounted on the upper side of the lower mounting plate 5031 and located behind the control assembly 501 to improve the installation convenience of the door lock device 100. Specifically, the lock base 31 and the actuator assembly 1 are both mounted on the lower mounting plate 5031.

[0070] In this embodiment, the electrical appliance is a cooking device, and the cooking device has a steaming function. A steam exhaust device is provided on the top of the inner tank 301. The exhaust device includes an exhaust cover 600 and a heat dissipation fan 800. An exhaust channel is formed between the exhaust cover 600 and the top of the inner tank 301. The air inlet end of the exhaust channel is connected to the inner cavity of the inner tank 301. The exhaust channel is used to discharge the steam in the inner tank 301. The air outlet of the exhaust channel is preferably provided at the front end of the exhaust channel. The heat dissipation fan 800 is used to guide the steam in the inner tank 301 to flow to the exhaust channel. The lower mounting side panel 5031 is located on the upper side of the exhaust cover 600 and extends forward from the exhaust cover 600 to reduce the probability of steam entering the control panel 500 and improve the safety of the control panel 500.

[0071] In this embodiment, a steam generator 1000 and a water tank 900 are further disposed between the inner container 301 and the housing 302. Water in the water tank 900 is supplied to the steam generator 1000, and the steam generator 1000 can convert water into steam for supply to the interior of the inner container 301. The steam generator 1000 is disposed at the rear side of the inner container 301, and the water tank 900 is disposed at the top of the inner container 301 and on one side of the exhaust cover 600.

[0072] It is understood that the specific structures of the steam exhaust device, steam generator 1000, and water tank 900 in the cooking device can be configured with reference to existing technologies. This is not the focus of this embodiment and will not be described in detail here. In another embodiment, the steam generation structure of the cooking device can adopt other existing structures. In another embodiment, the appliance can also be another type of appliance.

[0073] To improve the installation convenience of the actuator assembly 1, in this embodiment, the actuator assembly 1 includes a drive seat 13, and the drive motor 11 is mounted on the drive seat 13. The drive seat 13 is used to fasten the actuator assembly 1 to the body 300 of the electrical appliance. The drive seat 13 and the lock seat 31 are separately provided and are respectively located at both ends of the slide rod 2. The first end of the slide rod 2 is slidably mounted on the drive seat 13. The provision of the drive seat 13 can realize the integrated arrangement of the drive assembly and also facilitate the coordinated arrangement of the slide seat 21 and the drive assembly.

[0074] The drive base 13 is fastened to the panel bracket 503 to facilitate installation of the actuator assembly 1 on the appliance. Because the drive base 13 is larger in the front-to-back direction than the slide bar 2, and the lower mounting side plate 5031 of the panel bracket 503 is not flush with the top support plate at the top of the inner container 301, to ensure the installation stability of the actuator assembly 1, the front bottom of the actuator assembly 1 is fastened to the panel bracket 503, and the rear bottom of the actuator assembly 1 has a support member 138, which is supported by the top support plate 304. This ensures that even if the lower mounting side plate 5031 and the top support plate 304 are not flush, the front and rear ends of the actuator assembly 1 are stably supported, thereby improving the installation stability of the actuator assembly 1.

[0075] Preferably, the bottom of the drive base 13 is fastened to the lower mounting side plate 5031 using fastening screws to ensure the stability of the fastening between the drive base 13 and the lower mounting side plate 5031. Preferably, at least two fastening screws are provided at intervals along the circumference of the drive base 13. Furthermore, the support member 138 can be fastened to the top support plate 304 using fastening screws to effectively secure both the front and rear ends of the drive base 13.

[0076] Furthermore, the drive base 13 includes a mounting base, the front bottom of which is fastened to the panel bracket 503, and the rear bottom of which is spaced apart from the top support plate 304. The bottom of the mounting base is provided with the aforementioned support member 138. This allows the gap between the mounting base and the top support plate 304 to be used to avoid certain structures on the top support plate 304, ensuring the rationality of the internal structural layout of the appliance. In this embodiment, the front portion of the exhaust cover 600 extends between the mounting base and the top support plate 304.

[0077] It is understandable that the shape of the mounting base can be specifically set according to the type of electrical appliance and the structure installed on the top support plate 304, and this embodiment does not impose any limitation.

[0078] like Figures 8 to 10 As shown, in this embodiment, in order to improve the overall structural aesthetics of the appliance, in this embodiment, the lock seat 31 is installed on the upper side of the lower mounting side plate 5031 so that the lock seat 31 is not exposed to the user's field of vision. Furthermore, the door lock unit includes a driven part 32, a mounting shaft 34, and a lock hook 33. The driven part 32 is fixedly connected to the mounting shaft 34 and is hinged or abutted with the second end of the slide bar 2; the mounting shaft 34 is rotatably mounted on the lock seat 31, and the axis of the mounting shaft 34 is the first axis; the lock hook 33 is fixedly mounted on the mounting shaft 34 and is used to cooperate with the lock component 200. This structural arrangement of the door lock unit can improve the convenience of connecting the door lock unit with the lock seat 31 and the slide bar 2.

[0079] Preferably, the lock hook 33 and the driven member 32 are located on opposite sides of the lock base 31, thereby allowing the slide bar 2 to be located above the lock base 31 to reduce interference between the slide bar 2 and the lock base 31. Simultaneously, the lock hook 33 is located below the lock base 31, facilitating its downward extension through the panel bracket 503 and thus facilitating engagement between the lock hook 33 and the lock component 200. In this embodiment, the lower end of the mounting shaft 34 and the lock hook 33 extend downward through the lower mounting side plate 5031.

[0080] In this embodiment, the door 400 includes an outer door 401 and an inner door spaced apart from each other in the front and rear directions, and a door frame connected to the top of the outer door 401 and the inner door. The door frame includes at least a top frame 402 connected between the top of the inner door and the outer door 401. The upper end of the outer door 401 extends upward from the top frame 402 so that the upper part of the outer door 401 can block the gap between the top of the inner tank 301 and the top of the casing 302, thereby improving the appearance of the appliance.

[0081] In this embodiment, the lock component 200 is mounted on the top frame 402 and extends along the height of the door 400. Specifically, when the door 400 is closed, the lock component 200 extends vertically, with the upper end of the lock component 200 lower than the upper end of the outer door 401. The lock hook 33 has a lock slot 331 with one side open. When the door lock unit is in the locked position, the lock component 200 is inserted into the lock slot 331 and abuts against the front wall of the lock slot 331, restricting the lock component 200 from moving forward relative to the door lock unit. This, in turn, limits the forward opening of the top end of the door 400 relative to the machine body 300, ensuring that the door 400 remains stably closed. The lock component 200 preferably has a circular shaft structure to prevent scratches on the lock hook 33.

[0082] Specifically, when the door lock unit is in the unlocked position, the notch of the lock slot 331 faces forward, allowing the lock component 200 to move in and out of the lock slot 331 in the front-to-back direction, so that the machine door 400 can be opened relative to the machine body 300. When the door lock unit is in the locked position, the notch of the lock slot 331 faces left and right to limit the lock component 200 from moving forward and out of the lock slot 331.

[0083] The groove wall of the lock groove 331 includes a limiting groove wall, which is an arc-shaped structure that cooperates with the outer peripheral surface of the lock component 200. When the door lock unit is in the locked position, the limiting groove wall is the front side groove wall of the lock groove 331. Therefore, through the fit between the limiting groove wall and the lock component 200, the lock component 200 is limited from escaping the lock groove 331 and the probability of the lock component 200 shaking in the lock groove 331 is reduced, thereby improving the stability and reliability of the cooperation between the door lock device 100 and the lock component 200.

[0084] A guide surface 332 is formed on the front side of the lock hook 33. The guide surface 332 is located in front of the lock slot 331 and extends forward from the notch of the lock slot 331 in a direction away from the notch of the lock slot 331. When the user closes the door and the door lock unit is in the locked position, the lock component 200 first contacts the guide surface 332. During the user's door closing process, the lock component 200 pushes against the guide surface 332 from front to back to guide the lock component 200 into the lock slot 331 of the lock hook 33. The specific structure of the lock hook 33 can be set with reference to the existing structure and will not be described in detail in this embodiment.

[0085] In this embodiment, the second end of the sliding rod 2 is hingedly connected to the driven part 32 via a hinge shaft 35. To facilitate the connection of the hinge shaft 35 with the sliding rod 2 and the driven part 32, the hinge shaft 35 is a bolt that passes through the sliding rod 2 and the driven part 32 in sequence, with the bolt head abutting the side of the sliding rod 2 away from the driven part 32. A fastening nut is threaded onto the bolt, abutting the side of the driven part 32 away from the sliding rod 2, so that the driven part 32 is sandwiched between the sliding rod 2 and the fastening nut, and both the driven part 32 and the sliding rod 2 can rotate relative to the bolt.

[0086] When the door lock unit is in the locked position, the hinge shaft 35 is spaced apart on the rear side of the mounting shaft 34, thereby avoiding interference between the slide bar 2 and the control panel 500, and allowing the mounting shaft 34 to be arranged forward, thereby making the mounting shaft 34 closer to the lock component 200, thereby reducing the size of the lock hook 33.

[0087] like Figures 10 to 13 As shown, in this embodiment, the rotation axis of the actuator 12 is parallel to the first axis and is spaced apart, and the rotation of the actuator 12 around the first rotation direction can push the slide bar 2 to move in a direction away from the rotation axis, so that the door lock unit is switched from the locked position to the unlocked position; the door lock device 100 also includes a reset member 4, which applies an elastic force to the slide bar 2 or the door lock unit to maintain or return the door lock unit to the locked position.

[0088] That is, in this embodiment, the actuating assembly 1 drives the door lock unit to switch from the locked position to the unlocked position to realize automatic opening of the machine door 400, thereby ensuring the reliability and safety of the door opening operation of the machine door 400; and the setting of the reset member 4 enables the door lock unit to automatically reset to the locked position when the pushing force applied by the actuating member 12 to the slide bar 2 is cancelled, so that the user can realize the cooperation between the door lock unit and the lock component 200 when closing the machine door 400 without any other operation, thereby improving the convenience of the door closing operation of the machine door 400; at the same time, this setting enables the actuating assembly 1 to only push the slide bar 2 to move in one direction, thereby simplifying the structure of the actuating member 12 and reducing the structural complexity of the actuating member 12 and the actuating assembly 1.

[0089] In other embodiments, the rotational switching of the door lock unit from the unlocked position to the locked position may also be driven by the actuating assembly 1 .

[0090] In this embodiment, a reset member 4 is disposed at the first end of the slide bar 2 to apply an elastic force to the first end of the slide bar 2, forcing the slide bar 2 away from the door lock assembly 3. This arrangement ensures that the elastic force applied by the reset member 4 is substantially along the extension direction of the slide bar 2, thereby preventing the forward and backward force generated by a user forcibly opening the door from being transmitted to the reset member 4. This allows the reset member 4 to stably apply a force to the door lock unit to maintain the locked position, preventing the door lock unit from rotating to the unlocked state, thereby effectively preventing the door 400 from being forcibly opened and effectively ensuring the safety and reliability of the door lock device 100 and the door 400. In other embodiments, the reset member 4 may also be disposed at the door lock unit to apply torque to the door lock unit to return it from the unlocked position to the locked position.

[0091] like Figures 11 to 13As shown, in order to improve the reliability of the sliding rod 2 in pushing the door lock unit to rotate, in this embodiment, the sliding rod 2 includes a connected rod body 22 and a slide 21, the first end of the rod body 22 is hinged to the slide 21, and the second end of the rod body 22 is hinged to the door lock unit, and the actuator 12 can push the slide 21 away from one end of the rod body 22, so that the slide 21 slides along the first direction and actuates the door lock unit to switch to the unlocked position.

[0092] This arrangement, because the rod body 22 is hingedly connected to the door lock unit, prevents the rod body 22 from becoming detached from the door lock unit due to assembly errors or other reasons, ensuring that the slide bar 2 is always connected to the door lock unit, thereby ensuring the reliability of the slide bar 2's push against the door lock unit. Furthermore, this arrangement allows the door lock unit to be reset either by the reset member 4 disposed on the slide bar 2 or by disposing the reset member 4 at the door lock unit, thereby increasing the flexibility of the reset member 4's arrangement. Specifically, the rod body 22 is hingedly connected to the driven member 32 via a hinge shaft 35. Furthermore, this arrangement allows the lock component 200 to rotate the door lock unit during forced opening or closing, thereby causing the door lock unit to deflect the rod body 22 relative to the slide 21, thereby reducing the impact of forced opening or closing on the slide 21 and, consequently, on the actuator assembly 1. Furthermore, the hinged connection between the rod body 22 and the slide 21 prevents damage caused by the rigid connection between the rod body 22 and the slide 21, thereby increasing the service life of the slide bar 2.

[0093] In other embodiments, the slide bar 2 may slide as a whole in the first direction, with the end of the slide bar 2 away from the drive assembly abutting the door lock unit. The actuator 12 pushes the slide bar 2 to slide in the first direction, thereby causing the door lock unit to rotate. In this configuration, to ensure reliable resetting of the door lock unit, the reset member 4 is preferably disposed on the door lock unit. For example, the reset member 4 is a torsion spring disposed on the mounting shaft 34.

[0094] The width of the sliding seat 21 in the second direction is greater than the width of the rod body 22 in the second direction, and the second direction is perpendicular to both the first direction and the first axis. This arrangement can improve the sliding connection convenience between the sliding rod 2 and the drive seat 13 while reducing the overall footprint of the sliding rod 2 and the door lock device 100, and facilitates the configuration of the sliding structure between the sliding rod 2 and the drive seat 13.

[0095] To facilitate the hinged connection between the rod body 22 and the slide 21, in this embodiment, hinge holes are formed on both the rod body 22 and the slide 21. The hinge holes of the rod body 22 and the slide 21 are aligned, and the rod fastener 23 passes through the two aligned hinge holes. A nut is threaded onto the rod fastener 23, and the rod body 22 and the slide 21 are sandwiched between the nut and the screw head of the rod fastener 23. In other embodiments, the rod body 22 and the slide 21 may also be connected using other existing structures capable of achieving hinged connection.

[0096] The slide 21 comprises a sliding portion and a connecting portion connected to each other. The sliding portion is slidably mounted on the drive base 13, and the connecting portion is connected to the rod 22. The width of the sliding portion in a second direction is greater than the width of the connecting portion in the second direction, and the second direction is perpendicular to the first direction. This arrangement facilitates better sliding engagement between the slide 21 and the drive base 13 by increasing the size of the sliding portion. Furthermore, since the width of the connecting portion is smaller than that of the sliding portion, the overall structural dimensions of the slide 21 are reduced, thereby reducing the overall footprint of the door lock device 100.

[0097] The motor shaft 111 of the drive motor 11 is connected to the actuator 12. The rotation of the motor shaft 111 drives the actuator 12 to rotate along an axis around the motor shaft 111. The rotation axis of the motor shaft 111 of the drive motor 11 is a third axis. The third axis is parallel to and spaced apart from the first axis. This allows the actuator 12 to rotate within a plane perpendicular to the third axis and push against the slide bar 2 within this plane. This simplifies the structure of the actuator assembly 1, reduces the footprint of the actuator assembly 1, and improves the reliability and convenience of the actuator 12 pushing against the slide bar 2. That is, in this embodiment, the motor shaft 111 of the drive motor 11 is arranged in a vertical direction.

[0098] In order to ensure that the actuator 12 rotates around the third axis and can selectively push the slide bar 2, the distance between the outer contour surface of the actuator 12 and the third rotating axis is not equidistant, and the actuator 12 has an actuating end 121 farthest from the third rotating axis. The outer contour surface of the actuator 12 partially forms an actuating surface, and the distance between the actuating surface and the third rotating axis gradually decreases from the actuating end 121 along the first rotation direction. During the rotation of the actuator 12 along the first rotation direction, the actuating surface can push the slide bar 2 to move in the direction away from the third axis.

[0099] Specifically, the actuating member 12 adopts a cam structure, that is, the actuating member 12 and the slide rod 2 cooperate to form a cam slider structure. When the door lock unit is in the unlocked position, the actuating end 121 abuts against the slide rod 2.

[0100] Furthermore, the drive base 13 has a mounting cavity. The motor housing 302 of the drive motor 11 is mounted on the upper exterior of the drive base 13, with the motor shaft 111 and actuator 12 extending downwardly into the mounting cavity. The slide 21 slides through the mounting cavity. This arrangement allows the underside of the drive base 13 to be connected to the panel bracket 503 while conveniently securing the drive motor 11 to the drive base 13. The mounting cavity also protects the actuator 12 and the first end of the slide 2. In other embodiments, the drive base 13 may also be open at the top.

[0101] like Figure 10 、 Figure 11 and Figure 13As shown, to facilitate installation of the actuator 12 and the slide rod 2 within the drive base 13, the base includes a detachably connected base and an upper cover 132. The base and upper cover 132 together form a mounting cavity. The drive motor 11 is mounted on the upper cover 132, and the slide 21 is slidably mounted on the base. The base and upper cover 132 can be snap-fitted or fastened with screws.

[0102] The upper cover 132 is provided with an avoidance through-hole, and a fixing column 1321 is protruded on the side facing away from the main base body 131, and at least two fixing columns 1321 are arranged at intervals around the avoidance through-hole; the motor housing 302 of the drive motor 11 extends outward with a mounting ear plate, and the mounting ear plate and the fixing column 1321 are arranged in a one-to-one correspondence, and the mounting ear plate and the fixing column 1321 are fastened by fasteners. The motor shaft 111 and the actuator 12 enter and exit the installation cavity through the avoidance through-hole. This arrangement can realize the installation of the drive motor 11 on the upper cover 132. At the same time, since the actuator 12 can enter and exit the installation cavity through the avoidance through-hole, the drive motor 11 and the actuator 12 can be pre-assembled and then the pre-assembled assembly can be installed on the upper cover 132, thereby improving the disassembly and assembly efficiency of the actuator assembly 1.

[0103] The base includes a main body 131, which includes a bottom plate 1311 and side plates 1312 arranged around the periphery of the bottom plate 1311. The upper cover 132 abuts the upper end of the side plates 1312. The bottom plate 1311, the side plates 1312, and the upper cover 132 together form a mounting cavity. A connecting post 133 protrudes upward from the bottom plate 1311. The connecting post 133 has an internally threaded hole. The upper cover 132 has fastening holes that correspond to and align with the internally threaded holes. The upper cover 132 and the base are connected by fastening screws inserted through the fastening holes and the internally threaded holes. Preferably, multiple connecting posts 133 are arranged at intervals to ensure the secure fastening of the upper cover 132 and the base.

[0104] like Figures 12 to 16 As shown, to enhance the ease and stability of installation of the slide 21 on the drive base 13, the drive base 13 is provided with a mounting slot 1314, into which the slide 21 is slidably mounted. The mounting slot 1314 not only provides space for the installation of the slide 21 but also limits the sliding movement of the slide 21, ensuring the stability and reliability of the sliding fit of the slide 21 on the drive base 13. Specifically, the sliding portion of the slide 21 is slidably mounted in the mounting slot 1314.

[0105] In this embodiment, the mounting groove 1314 has two limiting groove walls that are opposite and spaced apart in the second direction, and the slide 21 forms limiting side portions 2122 on opposite sides of the second direction. The two limiting side portions 2122 respectively slide with the two limiting groove walls, thereby limiting the slide 21 from deflecting along the second direction in the mounting groove 1314, thereby ensuring the reliability of the slide 21 sliding along the first direction.

[0106] To better ensure the precision of forming the mounting groove 1314, a guide rib 1313 is protruding from the bottom plate 1311. The guide ribs 1313 extend along a first direction and are provided in two locations spaced apart and opposite to each other along a second direction, forming the mounting groove 1314 between the two guide ribs 1313. By providing the guide ribs 1313 to form the mounting groove 1314, the precision of the mounting groove 1314 can be controlled by controlling the machining precision of the guide ribs 1313, thereby reducing the machining precision requirements for the entire base and lowering machining costs.

[0107] Furthermore, the guide ribs 1313 and the side panels 1312 are spaced apart from each other, and both ends of the guide ribs 1313 along the first direction are connected to the side panels 1312 via connecting ribs, so that the main seat body 131 forms a rigid, integral structure. This improves the overall structural strength and rigidity of the guide ribs 1313 and reduces the probability of the guide ribs 1313 being deformed by the slide 21. In this embodiment, the main seat body 131 is integrally formed.

[0108] To further improve the sliding reliability of the slide 21, one of the drive base 13 and the slide 21 is provided with a guide groove 214, and the other is provided with a guide protrusion 134. The guide protrusion 134 is slidably inserted into the guide groove 214, and the guide groove 214 extends along the first direction. Thus, the sliding of the guide protrusion in the guide groove 214 achieves guidance of the movement of the slide 21 in the first direction.

[0109] It is worth noting that in this embodiment, the dual guidance of the sliding of the slide 21 is achieved through the cooperation between the slide 21 and the mounting groove 1314 and the cooperation between the guide protrusion 134 and the guide groove 214, which can ensure the sliding installation reliability of the slide 21 at the drive seat 13; in other embodiments, only the cooperation between the slide 21 and the mounting groove 1314 can be set to achieve the sliding guidance of the slide 21, or only the cooperation between the guide groove 214 and the guide protrusion 134 can be set to achieve the sliding guidance of the slide 21.

[0110] In this embodiment, both ends of the guide slot 214 along the first direction are closed, and when the door lock unit is in the locked position, the guide protrusion 134 abuts against one end wall of the guide slot 214, and when the door lock unit is in the unlocked position, the guide protrusion 134 abuts against the other end wall of the guide slot 214. As a result, both ends of the guide slot 214 can limit the sliding travel of the guide protrusion 134 within the guide slot 214. That is, the cooperation between the guide protrusion 134 and the guide slot 214 can limit the sliding travel of the slide 21 relative to the drive base 13 along the first direction.

[0111] In this embodiment, the bottom of the installation cavity is provided with a guide protrusion 134, and the guide slot 214 is provided on the slide 21. In other embodiments, the guide protrusion 134 can also be provided on the slide 21, and the guide slot 214 can be provided on the drive seat 13.

[0112] Furthermore, the upper cover 132 and the base are fastened by fasteners passing through the upper cover 132 and the guide protrusion 134, so that the guide protrusion 134 forms a connection structure between the upper cover 132 and the base, thereby reducing the number of separately set connection structures, simplifying the structure of the base, and improving the compactness of the structure.

[0113] The slide 21 includes a slide plate 211 and a panel 212 perpendicularly disposed around the periphery of the slide 211. The slide 211 is slidably supported on the bottom plate 1311 of the main seat 131. The panel 212 protrudes upward from the slide 211, and the actuator 12 abuts against the panel 212 to resist the movement of the slide rod 2. This arrangement increases the contact area between the slide 21 and the actuator 12 while preventing the slide 21 from being too heavy. The slide 21 and the panel 212 together form a receiving groove 217.

[0114] In this embodiment, the side panel 212 facing the actuator 12 forms a pressing portion 2121 capable of abutting the actuator 12. The two side panel portions 212 disposed opposite each other in the second direction form limiting side portions 2122. The limiting side portions 2122 and the pressing portion 2121 are smoothly connected by an arc-shaped transition portion 2124.

[0115] Furthermore, the enclosing plate portion 212 further includes an enclosing plate head portion 2123 connected between the two limiting side portions 2122 at one end away from the pressing portion 2121. The enclosing plate head portion 2123 has a flared U-shaped structure, with the opening of the U-shaped structure facing the pressing portion 2121. This allows the width of the enclosing plate portion 212, at least partially in the second direction, to gradually decrease in a direction away from the pressing portion 2121. This allows the width of the end of the slide 21 away from the actuator 12 to be smaller than the width of the end of the slide 21 facing the actuator 12. That is, in this embodiment, the portion of the slide 21 formed by the two limiting side portions 2122 and the pressing portion 2121 forms the sliding portion, and the portion formed by the enclosing plate head portion 2123 forms the connecting portion.

[0116] The slide portion 211 is provided with a protruding boss portion 213, and the guide groove 214 is arranged in a one-to-one correspondence with the boss portion 213. The guide groove 214 passes through the boss portion 213 and the slide portion 211 from top to bottom, thereby increasing the depth of the guide groove 214 in the third direction, thereby increasing the matching area between the groove wall of the guide groove 214 and the guide protrusion 134, ensuring the stability and reliability of the guiding matching between the slide seat 21 and the drive seat 13, and reducing the probability of the slide seat 21 being deformed by the pressure of the guide protrusion 134, thereby improving the service life of the door lock device 100.

[0117] The guide groove 214 is preferably an oblong groove, i.e., both ends of the guide groove 214 along the first direction have arc-shaped groove walls, and the cross-section of the guide protrusion 134 is a circular or oblong cross-section, thereby improving the reliability of the cooperation between the guide protrusion 134 and the guide groove 214. Preferably, two guide grooves 214 are provided in the second direction, opposite each other and spaced apart, with the guide protrusions 134 and guide grooves 214 provided in a one-to-one correspondence, to ensure the stability and reliability of the guide of the sliding of the slide 21.

[0118] In this embodiment, the reset member 4 is disposed between the slide seat 21 and the drive seat 13 to improve the convenience of disposing the reset member 4. Specifically, the reset member 4 is a spring, and the spring extends along the first direction.

[0119] Specifically, the drive seat 13 has a sliding bottom surface for slidably mounting the slide rod 2. The sliding bottom surface is provided with a mounting boss 135. The bottom of the receiving groove 217 is provided with a relief opening 2111. The mounting boss 135 passes through the relief opening 2111 and extends into the receiving groove 217. The first end of the reset member 4 abuts against a side wall of the receiving groove 217, and the second end of the reset member 4 abuts against the mounting boss 135. This arrangement fully utilizes the internal space of the slide seat 21, avoids the additional space occupied by the reset member 4 disposed outside the slide seat 21, and improves the overall compactness of the door lock device 100.

[0120] In this embodiment, the bottom of the mounting groove 1314 forms a sliding bottom surface, that is, the bottom of the mounting groove 1314 is protruding with a mounting boss 135, the first end of the reset member 4 is in contact with the pressing portion 2121, and the reset member 4 is located between the two mounting bosses 135.

[0121] Furthermore, a first boss portion 216 is protruded from the side of the pressing portion 2121 away from the actuator 12, and the first boss portion 216 extends along the first direction. The first end of the reset member 4 is sleeved on the first boss portion 216 to improve the installation convenience of the reset member 4 on the slide 21 and provide guidance for the deformation of the reset member 4.

[0122] Furthermore, two limiting portions 215 are projecting from the inner side surface of the pressing portion 2121. The two limiting portions 215 are spaced apart and opposed to each other in the second direction. The first boss portion 216 is spaced apart between the two limiting portions 215, and the limiting portions 215 are capable of abutting against the mounting boss 135. By providing the limiting portions 215, the abutment between the limiting portions 215 and the mounting boss 135 can limit the compression stroke of the reset member 4, thereby preventing damage to the reset member 4 due to excessive compression and ensuring the reliability of the reset member 4.

[0123] To enhance the fit between the reset member 4 and the mounting boss 135, the mounting boss 135 has a receiving cavity 1351 opening toward the abutting portion 2121. The second end of the reset member 4 extends into the receiving cavity 1351 and abuts against the wall of the cavity 1351, thereby preventing the reset member 4 from losing contact with the mounting boss 135. Furthermore, a second boss portion 137 is protruding from the wall of the cavity 1351 opposite the opening. The second end of the reset member 4 is sleeved onto the second boss portion 137 to further prevent the reset member 4 from separating from the mounting boss 135.

[0124] In this embodiment, a viewing window 1352 is formed through the wall of the accommodating cavity 1351 on one side away from the bottom plate 1311. The viewing window 1352 facilitates viewing the installation status of the reset member 4 within the accommodating cavity 1351 and allows for adjustment of the installation of the reset member 4 within the accommodating cavity 1351. Furthermore, the provision of the viewing window 1352 helps reduce the weight of the base.

[0125] Furthermore, a reinforcing rib 136 is provided on the side of the mounting boss 135 facing away from the reset member 4. The reinforcing rib 136 serves to increase the structural strength of the mounting boss 135 on the side facing away from the reset member 4, thereby preventing the mounting boss 135 from being deformed or even damaged by the pressure of the reset member 4, thereby increasing the service life of the mounting boss 135 and thus the service life of the door lock device 100. The reinforcing ribs 136 preferably extend along the third direction and are provided at least two at intervals along the second direction to provide additional structural reinforcement.

[0126] To control the movement of the slider and improve the reliability of door opening control, in this embodiment, the door lock device 100 also includes a detection member 5. The detection member 5 is used to detect the position of the actuating end 121. The detection of the detection member 5 can thus determine the start and stop timing of the drive motor 11. The detection member 5 is in communication with the control panel 500.

[0127] In this embodiment, the detection member 5 has a triggering state triggered by the actuating end 121 and a non-triggering state not triggered by the actuating member 12. When the detection member 5 is in the triggering state, the actuating member 12 is separated from the sliding rod 2, and the door lock unit is in the locked position.

[0128] In this embodiment, the detection member 5 is a microswitch having a trigger portion 51. When the trigger portion 51 abuts the actuating end 121, the detection member 5 is in a triggered state; when the actuating end 121 is separated from the trigger portion 51, the detection member 5 is in a non-triggered state. Contact between the actuating end 121 and the trigger portion 51 switches the detection member 5 from the non-triggered state to the triggered state, resulting in high detection accuracy. In other embodiments, the detection member 5 may be a non-contact sensor, such as a photoelectric sensor.

[0129] The position of the actuating end 121 when triggering the detection member 5 is defined as the first position, the position of the actuating end 121 when abutting against the slide bar 2 is defined as the second position, and the rotation angle of the actuating member 12 from the first position to the second position is A, A<2s×ω, ω is the rotation speed of the drive motor 11.

[0130] In this embodiment, the detection member 5 is installed in the mounting cavity to protect it. To facilitate installation of the detection member 5, a mounting post 139 is provided at the bottom of the mounting cavity. The housing of the detection member 5 is connected to the mounting post 139 via screws provided between the two. Preferably, two mounting posts 139 are provided at intervals to ensure stable installation of the detection member 5 within the drive seat 13.

[0131] Preferably, the mounting column 139 includes a supporting column portion 1391 and a positioning column portion 1392 coaxially connected, the end of the supporting column portion 1391 away from the positioning column portion 1392 is vertically connected to the bottom plate portion 1311, and the outer diameter of the supporting column portion 1391 is larger than the outer diameter of the positioning column portion 1392, so that the end face of the supporting column portion 1391 connected to the positioning column portion 1392 forms a positioning step surface. A positioning hole is provided on the shell of the detection member 5, the positioning column portion 1392 is inserted into the positioning hole, and the shell is supported on the positioning step surface. The shell and the mounting column 139 are fastened by a fastening screw passing through the positioning column portion 1392. The structural design of this type of mounting column 139 is conducive to ensuring the installation reliability and installation convenience of the detection member 5 on the drive seat 13.

[0132] Furthermore, the detection component 5 is provided with a wiring terminal, and the side panel portion 1312 of the base is provided with a threading hole at a position corresponding to the wiring terminal, so as to allow the connecting wires of the wiring terminal to be led out for connection with the control panel 500.
