DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0031] In the description of the present application, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, it is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the product of the invention is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0032] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0034] As described in the background art, in the related art, since the handle on the door lock is still thicker on the side close to the door frame (the thickness direction is perpendicular to the door body), it is easy to scratch the door frame (or the decoration on the door frame) when the door is opened inward. Moreover, when the handle is close to the door frame, the human hand may grab the handle from the side close to the door frame, and the human hand is easily clamped by the door frame and the handle when opening and closing the door, so there is a problem of insufficient safety.

[0035] To this end, an embodiment of the present application provides a door lock, which limits the opening of the handle space to face away from the door frame, so that the side of the handle assembly close to the door frame can have a thinner size, thereby making it difficult for the handle assembly of the door lock to interfere with the door frame, while also reducing the risk of people's hands being pinched when opening and closing the door.

[0036] Figure 1 This is a first schematic diagram of a door lock in an embodiment of the present application; Figure 2 This is a second schematic diagram of a door lock in an embodiment of the present application; Figure 3 This is a schematic diagram of the coordination of a door lock, a door body 002 and a door frame 001 in one embodiment of the present application. Figures 1 to 3As shown, the door lock provided by the embodiment of the present application includes a front panel assembly 100 and a handle assembly 200. The front panel assembly 100 has a front surface 101. The handle assembly 200 has a fixed end 201 and a gripping end 202 opposite to each other. The fixed end 201 is connected to the front surface 101, and the gripping end 202 is spaced apart from the front surface 101 in the thickness direction of the door lock. A handle space 300 is formed between the handle assembly 200 and the front surface 101. The handle space 300 forms an opening between the gripping end 202 and the front surface 101. The handle space 300 is closed on the side close to the fixed end 201. The opening of the handle space 300 faces away from the side of the door lock used to cooperate with the door frame 001. The thickness dimension of the door lock at the fixed end 201 is smaller than the thickness dimension at the gripping end 202. The thickness direction of the door lock is perpendicular to the front surface 101. In this embodiment, the extension direction of the handle assembly from the fixed end 201 to the clamping end is inclined to the front surface 101 of the front panel assembly 100. Since the handle space 300 needs to be inserted by a human hand, it will occupy a certain thickness space, and the fixed end 201 of the handle assembly 200 is located on the side of the handle space 300 away from its opening, which side is closed, and the handle space 300 is not formed between the fixed end 201 and the front surface 101, so the door lock can have a thinner size on one side of the fixed end 201. The fixed end 201 of the handle assembly 200 is the end adjacent to the door frame 001, so the overall thickness of the door lock at this position is thinner, which can effectively reduce the risk of interference between the door lock (specifically the handle assembly 200) and the door frame 001. Furthermore, since the opening of the handle space 300 faces away from the door frame 001, the user does not need to reach into the handle space 300 from the side where the door frame 001 is located, but is restricted to reaching into the handle space 300 from the opposite side to perform door opening and closing operations. In this case, the risk of the user's hand being pinched by the door frame 001 and the handle assembly 200 is reduced.

[0037] In this embodiment, the handle assembly 200 includes a fixing portion 203 and a gripping portion 204, a fixing end 201 is formed on the fixing portion 203, one end of the gripping portion 204 is connected to the fixing portion 203, and one end of the gripping portion 204 away from the fixing portion 203 forms a gripping end 202, and the gripping portion 204 gradually moves away from the front surface 101 along the end close to the fixing portion 203 to the gripping end 202. It should be understood that the gripping end 202 of the handle assembly 200 is a portion for forming the opening edge of the handle space 300, and the fixing end 201 of the handle assembly 200 is a position for connecting the front panel assembly 100. In other optional embodiments, the fixing portion 203 may also be omitted, and one end of the gripping portion 204 may be directly connected to the front surface 101 to form the fixing end 201.

[0038] Optionally, the angle α between the grip portion 204 and the front surface 101 is 15° to 50°; further, the angle α is 25° to 40°; in a specific embodiment, the angle α is 30°. In this embodiment, the surface of the grip portion 204 facing the front panel assembly 100 and the surface facing away from the front panel assembly 100 are parallel to each other.

[0039] In this embodiment, the projections of the fixing portion 203 and the gripping portion 204 on the front surface 101 are arranged in the first direction (the direction of arrows ab in the figure). The front surface 101 has a first edge 1011 and a second edge 1012 that are opposite to each other in the first direction, and the projections of the fixing end 201 and the gripping end 202 on the front surface 101 are spaced apart in the first direction, and the fixing end 201 is closer to the first edge 1011 relative to the gripping end 202. It can be understood that in the closed state, the first edge 1011 of the front surface 101 is located on the side of the front surface 101 adjacent to the door frame 001, and the second edge 1012 is the side of the front surface 101 away from the door frame 001. In this embodiment, the front surface 101 is rectangular, and the first edge 1011 and the second edge 1012 are parallel, and both are parallel to the door frame 001.

[0040] In this embodiment, the first edge 1011 is flush with the fixed end 201, and the projection of the gripping end 202 on the front surface 101 is spaced apart from the second edge 1012 in the first direction. It can be understood that when the first edge 1011 is flush with the fixed end 201, the size of the front surface 101 can be more fully utilized, the handle assembly 200 has a size as wide as possible, and it is also beneficial to expand the width of the handle space 300 in the first direction, so that the user can hold the handle assembly 200 more easily.

[0041] The projection of the grip end 202 on the front surface 101 is spaced from the second edge 1012 in the first direction, so that a portion of the front surface 101 can be observed when the user is facing the door lock. In this embodiment, the front surface 101 is provided with a touch area 105, and the touch area 105 is located between the second edge 1012 and the projection of the grip end 202 on the front surface 101. The touch area 105 is arranged between the second edge 1012 and the projection of the grip end 202 on the front surface 101, so that the user can observe and operate the door lock when facing the door lock. The touch area 105 corresponds to the touch circuit board 150 (see FIG. 1 ) inside the front panel assembly 100. Figure 6 ).

[0042] Furthermore, the front surface 101 has a third edge 1013 and a fourth edge 1014 that are opposite to each other in the second direction (the cd direction in the figure), the second direction is perpendicular to the first direction, and the two ends of the handle space 300 in the second direction extend to the third edge 1013 and the fourth edge 1014. Such a configuration makes full use of the area of ​​the front surface 101, so that the handle space 300 has a longer size, thereby facilitating the user to hold and operate the handle assembly 200. In this embodiment, the two ends of the fixing portion 203 in the second direction are flush with the third edge 1013 and the fourth edge 1014, respectively, and the lengths of the fixing portion 203 and the gripping portion 204 in the second direction are consistent. Optionally, the two ends of the handle space 300 in the second direction are open.

[0043] Figure 4 This is a first split view of the front panel assembly 100 and the handle assembly 200 in one embodiment of the present application; Figure 5 This is a second split view of the front panel assembly 100 and the handle assembly 200 in one embodiment of the present application. Figures 4 to 5 As shown, one of the handle assembly 200 and the front panel assembly 100 is provided with an elastic buckle 205, and the other is provided with a card hole 102, and the elastic buckle 205 is plugged and matched with the card hole 102. Through the cooperation of the elastic buckle 205 and the card hole 102, the front panel assembly 100 and the handle assembly 200 can be effectively connected, which can play a role of pre-positioning when assembling the door lock, and facilitate the subsequent fastening operation. Specifically in this embodiment, the handle assembly 200 is provided with two pairs (a total of four) of elastic buckles 205 on the side facing the front panel assembly 100, and the front panel assembly 100 is provided with two pairs (a total of four) card holes 102 to cooperate with them. The three pairs of elastic buckles 205 are arranged at intervals in the second direction, and the two elastic buckles 205 in each pair of elastic buckles 205 are spaced in the first direction. Specifically, the elastic buckle 205 is provided on the side of the fixing portion 203 facing the front panel assembly 100. It can be understood that in other embodiments, the relative positions of the elastic buckle 205 and the locking hole 102 can be swapped, and their number can be increased or decreased as needed.

[0044] Furthermore, one of the handle assembly 200 and the front panel assembly 100 is provided with a positioning column 206, and the other is provided with a positioning hole 103, and the positioning column 206 is plugged into the positioning hole 103. The positioning column 206 is plugged into the positioning hole 103, and can also play a role in pre-positioning the handle assembly 200 and the front panel assembly 100, which is convenient for assembly and also conducive to the reliability of the combination of the two. In this embodiment, the positioning column 206 is provided on the handle assembly 200, specifically, on the side of the fixing portion 203 facing the front panel assembly 100, and the positioning hole 103 is provided on the front surface 101 of the front panel assembly 100. In this embodiment, the number of the positioning column 206 and the positioning hole 103 are two respectively, and the positioning column 206 is provided between two pairs of elastic buckles 205, and the two pairs of elastic buckles 205 correspond to the two positioning columns 206 respectively.

[0045] Further, a mounting boss 104 is convexly provided on the front surface 101, and a mounting hole penetrating the front panel assembly 100 is provided on the mounting boss 104, and a mounting groove 207 is provided on the handle assembly 200, and a screw hole is provided at the bottom of the mounting groove 207, and the mounting boss 104 is plugged and matched with the mounting groove 207 and locked by a screw 106, and the screw 106 passes through the mounting hole and is screwed with the screw hole. In this embodiment, three mounting bosses 104 are provided on the front surface 101, and the three mounting bosses 104 are arranged at intervals in the second direction, and three mounting grooves 207 are correspondingly provided on the fixing portion 203 of the handle assembly 200. Through the mounting groove 207 and the mounting boss 104, the relative position of the handle assembly 200 and the front panel assembly 100 can be effectively located, so that it is convenient to install the screw 106 for fixing. In this embodiment, two mounting holes are provided on each mounting boss 104, so a total of six screws 106 are used to fix the front panel assembly 100 and the handle assembly 200.

[0046] Figure 6 This is an exploded view of a door lock in the thickness direction in one embodiment of the present application. Figure 6 As shown, in order to realize the intelligence of the door lock, a number of electronic devices are arranged in the handle assembly 200 and the front panel assembly 100. In this embodiment, the handle assembly 200 includes a front shell 210 and a rear shell 220, and the front shell 210 and the rear shell 220 can enclose a cavity for accommodating electronic devices, and the front shell 210 and the rear shell 220 together define the outer contour of the handle assembly 200. Similarly, the front panel assembly 100 includes a decorative plate 110 and a bottom plate 120, and the bottom plate 120 and the decorative plate 110 can enclose a cavity for accommodating electronic devices. A silicone pad 121 is arranged on the side of the bottom plate 120 away from the decorative plate 110, and the bottom plate 120 is pressed against the door body 002 through the silicone pad 121.

[0047] In this embodiment, the side of the decorative plate 110 facing away from the bottom plate 120 forms the front surface 101, the front shell 210 and the rear shell 220 are spliced ​​in the thickness direction of the door lock, and the rear shell 220 is connected to the decorative plate 110. A part of the front shell 210 and a part of the rear shell 220 together form a gripping portion 204, and another part of the front shell 210 and another part of the rear shell 220 together form a fixing portion 203.

[0048] In this embodiment, the handle assembly 200 further includes a recognition module for identifying human body information, the recognition module includes a camera 231, and the recognition module further includes an indicator light 243, at least one of a humanoid monitoring radar 244 and a fill light, and the indicator light 243, at least one of a humanoid monitoring radar 244 and a fill light and the camera 231 are arranged at intervals in the second direction. In this embodiment, the gripping portion 204 is inclined relative to the front surface 101, and its surface on the side away from the front panel assembly 100 is at an acute angle to the front surface 101; and the surface of the fixing portion 203 on the side away from the front panel assembly 100 can be parallel to the front surface 101 or have a smaller inclination angle. Therefore, the recognition module is arranged in the gripping portion 204, and the side of the gripping portion 204 away from the front panel assembly 100 has a plane parallel to the front surface 101, and the camera 231 is exposed from the plane, which is conducive to facing the recognition module to the front of the door lock.

The touch circuit board 150 corresponds to the touch area 105 on the decorative plate 110 .

[0054] To summarize, the door lock provided in the embodiment of the present application includes a front panel assembly 100 and a handle assembly 200, the front panel assembly 100 having a front surface 101, the handle assembly 200 having a fixed end 201 and a holding end 202 relative to each other, the fixed end 201 being connected to the front surface 101, a handle space 300 being formed between the handle assembly 200 and the front surface 101, the handle space 300 forming an opening between the holding end 202 and the front surface 101, the handle space 300 being closed on a side close to the fixed end 201, the opening of the handle space 300 being oriented away from a side of the door lock for cooperating with the door frame 001, the thickness dimension of the door lock at the fixed end 201 being smaller than the thickness dimension at the holding end 202, and the thickness direction of the door lock being perpendicular to the front surface 101. Since the opening of the handle space 300 faces away from the side of the door lock used to cooperate with the door frame 001, and the gripping end 202 of the handle assembly forms the opening of the handle space 300, it means that the fixed end 201 of the handle assembly is closer to the side of the door lock and the door frame 001 than the gripping end 202. Since the fixed end 201 is not separated from the front panel assembly 100 to form the handle space 300, the thickness of the door lock at the fixed end 201 is smaller than the thickness at the gripping end 202, making the entire door lock thinner on the side close to the door frame 001. Therefore, when opening and closing the door, the handle assembly 200 of the door lock is not easy to interfere with the door frame 001 or objects on the door frame 001 (such as decorations), and is not easy to scratch the door frame 001 or objects on the door frame 001. Furthermore, since the opening of the handle space 300 is oriented away from the side of the door lock that cooperates with the door frame 001, when the user uses the handle assembly 200 of the door lock, the user will not insert the hand into the handle space 300 from the side where the door frame 001 is located, thereby reducing the risk of the hand being squeezed by the door frame 001 and the door lock, thereby improving safety.

[0055] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed in the present application should be covered within the protection scope of the present application.
