[0032] In the related art, a door lock is generally provided between the body and the door of an electrical device. When the door lock is closed, the sealing and safety of the door body on the body can be ensured, and when the door lock is opened, it is convenient to put and take out items. Generally, door locks have the problems of complex structure, large space occupation, and high production and processing costs. The embodiment of the present application provides a door lock that can at least solve the technical problem that the handle designed on the surface of the door body affects the appearance to a certain extent.

[0033] Combine the following Figure 1-Figure 5 The present application is described with reference to specific embodiments:

[0034] like Figure 1-Figure 5As shown, the embodiment of the present application provides a door lock 100, which includes a lock body 110, a lock buckle 150, a movable member 120 and a first elastic member 130. At least part of the lock buckle 150 can reciprocate in the lock body 110; the movable member 120 can be rotatably installed in the lock body 110 and is detachably connected to the lock buckle 150; the first elastic member 130 is connected between the lock body 110 and the movable member 120; wherein, when the lock buckle 150 moves into the lock body 110, the lock buckle 150 drives the movable member 120 to rotate to a restrained position, and the lock buckle 150 is locked with the movable member 120; when the lock buckle 150 moves out of the lock body 110, the lock buckle 150 and the movable member 120 are unlocked, and the first elastic member 130 drives the movable member 120 to return to the initial position.

[0035] refer to Figure 2 and Figure 3 , is a schematic diagram of the structure of the movable member 120 of the door lock 100 in the initial position in the embodiment of the present application, at which time the door lock 100 is in the unlocked state; Figure 4 and Figure 5 , is a structural diagram of the movable part 120 of the door lock 100 in the embodiment of the present application in the restrained position, at which time the door lock 100 is in a locked state.

[0036] A cavity is formed in the lock body 110, and at least a portion of the lock buckle 150 can extend into the cavity in the lock body 110 and move back and forth. When the door lock 100 is in an unlocked state, the lock buckle 150 can be arranged outside the lock body 110. When the door lock 100 is in a locked state, at least a portion of the lock buckle 150 is locked in the lock body 110.

[0037] The movable member 120 and the first elastic member 130 are movably installed in the cavity. The movable member 120 is rotatably arranged in the cavity. The first elastic member 130 is connected between the movable member 120 and the lock body 110 to apply an elastic force to the movable member 120 to keep it in the initial position. When the door lock 100 switches from the unlocked state to the locked state, the lock catch 150 moves into the lock body 110 and connects with the movable member 120, and drives the movable member 120 to rotate from the initial position to the restrained position in the cavity. 20 is rotated to the restrained position, at least part of the lock catch 150 is locked in the cavity, and the door lock 100 is switched to the locked state; in the process of switching the door lock 100 from the locked state to the unlocked state, the lock catch 150 moves outside the lock body 110 and drives the movable part 120 to rotate, and under the condition that the movable part 120 rotates to a certain angle, the lock catch 150 is separated from the movable part 120, and the movable part 120 is reset to the initial position under the action of the first elastic part 130, and the door lock 100 is switched to the unlocked state.

[0038] According to the door lock 100 provided in the embodiment of the present application, the lock catch 150 is pushed into the lock body 110 to drive the movable member 120 to rotate from the initial position to the restrained position, and the movable member 120 locks the lock catch 150, pulls the lock catch 150 to move outward, the lock catch 150 drives the movable member 120 to rotate to the initial position, and releases the lock when the lock catch 150 is separated from the movable member 120, and the first elastic member 130 drives the movable member 120 to return to the initial position. The door lock 100 in this embodiment has fewer parts, simple structure and action, small space occupation, low production and assembly difficulty, and low production cost.

[0039] In some embodiments, Figure 1-Figure 5 As shown, the movable member 120 may be provided with a locking portion 121 and a connecting portion 125 , the locking portion 121 may lock the lock buckle 150 , and the connecting portion 125 may be connected to the first elastic member 130 .

[0040] The movable member 120 may be provided with a locking portion 121, which is used to cooperate with the lock buckle 150. When at least part of the lock buckle 150 enters the lock body 110, the lock buckle 150 is connected with the locking portion 121. The lock buckle 150 drives the locking portion 121 to move to drive the movable member 120 to rotate. When the movable member 120 rotates to the restrained position, the locking portion 121 can lock the lock buckle 150. When the movable member 120 rotates to the initial position, the locking portion 121 releases the locking of the lock buckle 150, and the lock buckle 150 can be separated from the locking portion 121. The movable member 120 is also provided with a connecting portion 125 connected to the first elastic member 130. The first elastic member 130 applies elastic force to the connecting portion 125 to keep the movable member 120 in the initial position.

[0041] In some embodiments, Figure 1-Figure 5 As shown, the movable member 120 can be rotatably connected to the lock body 110 through the rotating shaft 111, and the locking portion 121 and the connecting portion 125 can be respectively arranged on both sides of the rotating shaft 111.

[0042] The movable member 120 is rotatably connected to the cavity of the lock body 110 through the rotating shaft 111. In one example, the rotating shaft 111 can be set on the lock body 110, and the movable member 120 is provided with an axial hole that matches the rotating shaft 111. In another example, the rotating shaft 111 can be set on the movable member 120, and the lock body 110 is provided with an axial hole that matches the rotating shaft 111. The locking portion 121 and the connecting portion 125 are respectively arranged on both sides of the rotating shaft 111. When the movable member 120 rotates, the locking portion 121 and the connecting portion 125 rotate in different directions, which can increase the rotation angle range of the locking portion 121 and the connecting portion 125, and facilitate the connection between the first elastic member 130 and the connecting portion 125, so as to avoid the first elastic member 130 interfering with the movement of the locking portion 121.

[0043] In some embodiments, when the movable part 120 is located in the constrained position, the movable part 120 can be limited by the lock body 110. Exemplarily, a snap-fit ​​structure can be provided between the movable part 120 and the lock body 110. The snap-fit ​​structure can include a snap protrusion and a snap groove, one of which is provided on the movable part 120, and the other is provided on the door body, so that the movable part 120 is limited in the constrained position and the lock buckle 150 is locked.

[0044] In some embodiments, Figure 1-Figure 5 As shown, the first elastic member 130 may include a torsion spring, and two ends of the torsion spring may be connected to the lock body 110 and the connecting portion 125 respectively.

[0045] The torsion spring has a first end and a second end, the first end of the torsion spring is rotatably connected to the lock body 110, and the second end of the torsion spring is rotatably connected to the connecting portion 125. In an example, the second end of the torsion spring is located between the first end of the torsion spring and the rotating shaft 111, so that the connecting portion 125 moves between the first end of the torsion spring and the rotating shaft 111, wherein the torsion spring is set in a compressed state, and the connecting portion 125 is located on both sides of the line connecting the first end of the torsion spring and the rotating shaft 111 in the initial position and the constrained position, respectively, so that the torsion spring can drive the connecting portion 125 to limit on both sides of the line. When the movable part 120 is in the initial position, the connecting part 125 is located on the first side of the line connecting the first end of the torsion spring and the rotating shaft 111, and the torsion spring applies an elastic force to the connecting part 125 to keep the movable part 120 in the initial position; when the door lock 100 is locked, the lock buckle 150 pushes the locking part 121 to move and thereby drives the connecting part 125 to rotate. When the connecting part 125 rotates to the second side of the line connecting the first end of the torsion spring and the rotating shaft 111, the elastic force applied by the torsion spring is toward the second side of the line to drive the connecting part 125 to be limited in the constrained position, thereby limiting the locking part 121 and locking the lock buckle 150. The structure is simple and the locking is stable.

[0046] In one example, a first rotating rod is provided at the first end of the torsion spring, a second rotating rod is provided at the second end of the torsion spring, a first connecting hole is provided on the lock body 110, the first rotating rod is rotatably matched with the first connecting hole, a second connecting hole is provided on the connecting portion 125, and the second rotating rod is rotatably matched with the second connecting hole. In another example, connecting holes may be provided at the first end and the second end of the torsion spring, rotating rods may be provided on the lock body 110 and the connecting portion 125, and the rotating rods are matched with corresponding connecting holes.

[0047] In other embodiments, the first elastic member 130 may be a spring, and both ends of the spring are respectively connected to the lock body 110 and the connecting portion 125 . The specific connection method may refer to the above embodiment and will not be described in detail here.

[0048] In some embodiments, Figure 1-Figure 5As shown, the locking portion 121 may be provided with a locking groove 122 , and the lock buckle 150 may include a buckle portion 151 movable into the locking groove 122 , and when the movable member 120 is in the initial position, the opening side of the locking groove 122 faces the buckle portion 151 .

[0049] The locking groove 122 can be set with an opening at one end, and the opening direction is set toward the circumference of the rotating shaft 111. The buckle portion 151 can extend into the cavity in the lock body 110. When the movable part 120 is in the initial position, the opening of the locking groove 122 faces the buckle portion 151, so that when the lock buckle 150 enters the lock body 110, the buckle portion 151 can smoothly enter the locking groove 122 and abut against the locking groove 122 to drive the locking portion 121 to rotate.

[0050] In some embodiments, Figure 2 and Figure 3 As shown, when the movable part 120 is in the initial position, the side wall connected to the opening in the locking groove 122 is set at an angle with the moving direction of the lock buckle 150, so that the buckle part 151 of the lock buckle 150 can abut against the side wall of the locking groove 122, thereby pushing the locking part 121 to rotate around the rotating shaft 111, and the connection stability is high.

[0051] In some embodiments, Figure 1-Figure 5 As shown, the lock body 110 may be provided with a guide groove 112 , and at least a portion of the lock buckle 150 may reciprocate in the lock body 110 through the guide groove 112 .

[0052] The guide groove 112 is connected to the side wall of the lock body 110, and an opening is provided at one end of the guide groove 112 connected to the side wall of the lock body 110, and the buckle portion 151 of the lock buckle 150 can enter the guide groove 112 through the opening. The projection of the locking groove 122 of the locking portion 121 on the lock body 110 overlaps with the guide groove 112 at least partially, so that the buckle portion 151 can enter the locking groove 122 synchronously after entering the guide groove 112. When the movable member 120 is in the initial position, the projection of the opening of the locking groove 122 on the lock body 110 overlaps with the guide groove 112, so that the buckle portion 151 can smoothly enter the locking groove 122. When the movable member 120 is in the restrained position, the opening direction of the locking groove 122 corresponds to the side wall of the guide groove 112, so that the buckle portion 151 is limited in the locking groove 122.

[0053] In some embodiments, Figure 1-Figure 5As shown, the guide groove 112 can be set through the bottom wall of the lock body 110, and the buckle 151 of the lock buckle 151 can be set in a columnar shape. Exemplarily, the buckle 151 can be set in a cylindrical shape, and the lock buckle 150 passes through the guide groove 112 so that the buckle 151 enters the lock body 110 to push the movable part 120 in the lock body 110 to rotate. According to the guide groove 112 and the buckle 151 of this embodiment, the structure is simple and the volume is small, which reduces the space occupied by the door lock 100. Under the condition that the lock buckle 151 is installed on the door body, there is only one columnar protruding buckle 151 on the door body, which occupies less space in the thickness direction of the door body, and the door body can be made thinner, optimizing the space layout.

[0054] In some embodiments, Figure 1 As shown, the lock buckle 150 may also be provided with a boss 152, the buckle 151 is disposed on the boss 152, and a reinforcement structure may be provided between the boss 152 and the buckle 151 to strengthen the structural strength of the lock buckle 150 and improve the stability of the door lock 100. The shape of the boss 152 may match the shape of the guide groove 112, and when the lock buckle 150 moves into the lock body 110, the boss 152 enters the guide groove 112, so that when the door lock 100 is locked, the boss 152 can cooperate with the guide groove 112 to limit the position, thereby improving the stability of the connection.

[0055] In some embodiments, Figure 1-Figure 5 As shown, the portion of the lock body 110 with the guide groove 112 is protruded in the direction close to the lock buckle 151, so that when the lock body 110 is installed on the machine body and the lock buckle 150 is installed on the door body, it is convenient for the buckle part on the lock buckle 150 to enter the lock body 110 for locking and fitting.

[0056] In some embodiments, Figure 2-Figure 5 As shown, the lengths of the two side walls connected to the opening of the locking groove 122 are different, wherein the side wall of the locking groove 122 close to the opening is the first side wall 123, and the side wall away from the opening is the second side wall 124, and the length of the first side wall 123 is less than the length of the second side wall 124. When the movable member 120 is in the initial position, the opening direction of the locking groove 122 is set at an angle to the opening direction of the guide groove 112, the first side wall 123 can be retracted into the lock body 110, and the second side wall 124 can at least cover half of the width direction of the guide groove 112, so that the buckle 151 can contact the second side wall 124 after entering the guide groove 112, and enter the locking groove 122.

[0057] In some embodiments, Figure 4 and Figure 5As shown, when the movable part 120 rotates to the restrained position, the lock buckle 150 abuts against the end of the guide groove 112 away from the opening to limit the lock buckle 150, thereby limiting the locking portion 121 of the movable part 120 to prevent the movable part 120 from rotating too much.

[0058] In some embodiments, a limiting portion 113 may be provided in the lock body 110 , and the limiting portion 113 may be detachably connected to the locking portion 121 of the movable member 120 , and when the movable member 120 is rotated to the restrained position, the locking portion 121 of the movable member 120 may abut against the limiting portion 113 .

[0059] When the movable part 120 rotates to the constrained position, the locking portion 121 can abut against the limiting portion 113 to limit the locking portion 121, thereby limiting the rotation angle of the movable part 120 and preventing the movable part 120 from rotating too much. When the movable part 120 rotates to the initial position, the connecting portion 125 can abut against the limiting portion 113 to limit the connecting portion 125, thereby limiting the movable part 120 at the initial position, thereby preventing the buckle portion 151 of the lock buckle 150 from being unable to enter the locking groove 122 after the movable part 120 rotates out of position.

[0060] In some embodiments, Figure 1-Figure 5 As shown, the door lock 100 may further include a sensing member 170 and a trigger member 160. The sensing member 170 may be disposed in the lock body 110. The trigger member 160 may be disposed in the lock body 110 and detachably connected to the movable member 120 so as to reciprocate in the lock body 110 under the drive of the movable member 120 to trigger the sensing member 170 to determine the state of the door lock 100.

[0061] During the rotation of the movable member 120, the movable member 120 may contact the trigger member 160 to drive the trigger member 160 to move back and forth, and the sensor 170 may be triggered during the movement of the trigger member 160. For example, the sensor 170 may be a micro switch.

[0062] The sensor 170 can be used to send a signal of the state of the door lock 100 so that the electrical device can determine the switch state of the door body. In one example, when the sensor 170 is triggered, the door lock 100 is judged to be in an unlocked state, and when the sensor 170 is not triggered, the door lock 100 is judged to be in a locked state. In another example, when the sensor 170 is triggered, the door lock 100 is judged to be in a locked state, and when the sensor 170 is not triggered, the door lock 100 is judged to be in an unlocked state.

[0063] In some embodiments, when the movable part 120 is in the constrained position, the trigger part 160 may contact the sensing part 170, and when the movable part 120 is in the initial position, the trigger part 160 may be separated from the sensing part 170; or, when the movable part 120 is in the constrained position, the trigger part 160 and the sensing part 170 are separated, and when the movable part 120 is in the initial position, the trigger part 160 and the sensing part 170 are in contact.

[0064] The sensing member 170 may be provided with a sensing portion. When the trigger member 160 is connected to the sensing portion, the sensing member 170 is triggered. When the trigger member 160 is separated from the sensing portion, the sensing member 170 is not triggered.

[0065] In one example, the door lock 100 is in a locked state when the sensing member 170 is triggered, and is in an unlocked state when the sensing member 170 is not triggered, that is, when the movable member 120 is in a restrained position, the trigger member 160 can contact the sensing member 170, and when the movable member 120 is in an initial position, the trigger member 160 can be separated from the sensing member 170.

[0066] In another example, if Figure 2-Figure 5 As shown, when the sensing member 170 is triggered, the door lock 100 is in an unlocked state, and when the sensing member 170 is not triggered, the door lock 100 is in a locked state. When the movable member 120 is in a restrained position, the trigger member 160 and the sensing member 170 are separated, and when the movable member 120 is in an initial position, the trigger member 160 and the sensing member 170 are in contact.

[0067] In some embodiments, Figure 1-Figure 5 As shown, the door lock 100 may further include a second elastic member 140 , and the second elastic member 140 may be connected between the lock body 110 and the trigger member 160 .

[0068] The second elastic member 140 can apply an elastic restoring force to the trigger member 160 , and the movable member 120 can be separated from the trigger member 160 when the movable member 120 rotates to the initial position or the restrained position.

[0069] For ease of explanation, take the example of the movable part 120 separating from the trigger part 160 when it rotates to the initial position. When the movable part 120 is in the initial position, the trigger part 160 is in the first position. At this time, the trigger part 160 may trigger the sensing part 170 or may not trigger the sensing part 170. When the movable part 120 is in the restrained position, the movable part 120 drives the trigger part 160 to move to the second position. At this time, the trigger part 160 does not trigger the sensing part 170 or triggers the sensing part 170. When the movable part 120 rotates from the restrained position to the initial position, the movable part 120 and the trigger part 160 are gradually separated. The trigger part 160 can be reset to the first position under the action of the second elastic part 140 to ensure that the sensing part 170 can accurately reflect the state of the door lock 100.

[0070] In some embodiments, the movement direction of the trigger 160 in the lock body 110 may be consistent with or inconsistent with the movement direction of the lock buckle 150 in the lock body 110 .

[0071] In one example, if Figure 2-Figure 5 As shown, the movement directions of the trigger member 160 and the lock 150 can be consistent, the structure is simple and the driving is stable. When the lock 150 drives the locking part 121 on the movable part 120 to move, the locking part 121 can push the trigger member 160 to move in the same direction.

[0072] In another example, the moving directions of the trigger member 160 and the lock 150 can be set inconsistently. For example, with the moving direction of the lock 150 as the front-to-back direction, the trigger member 160 can move in the left-to-right direction. By providing an inclined guide structure on the trigger member 160, when the movable part 120 rotates, the connecting part 125 or the locking part 121 cooperates with the guide structure to drive the trigger member 160 to move in the left and right directions. This setting can reduce the thickness of the lock body 110 in the front-to-back direction and optimize the installation space.

[0073] In some embodiments, Figure 1-Figure 5 As shown, a guide channel 114 may be provided in the lock body 110 , and the trigger member 160 may reciprocate in the guide channel 114 .

[0074] The guide channel 114 is provided to limit the moving direction of the trigger member 160, so as to ensure that the trigger member 160 can effectively trigger the sensing member 170 in the moving direction. In one example, the movable member 120 and the second elastic member 140 are respectively provided at both ends of the guide channel 114, and the second elastic member 140 is provided in a compressed manner to apply an elastic force to the trigger member 160 in a direction close to the movable member 120, and during the rotation of the movable member 120, the trigger member 160 is driven to move by contacting with the trigger member 160 to overcome the elastic force of the second elastic member 140.

[0075] Among them, the second elastic member 140 can be a spring or an elastic rubber ring, etc., which is not specifically limited here. Taking the second elastic member 140 as a spring as an example, a first fixing portion 115 corresponding to the trigger member 160 is provided on the lock body 110, and a second fixing portion 163 is provided at one end of the trigger member 160 facing the second elastic member 140. The first fixing portion 115 and the second fixing portion 163 are respectively used to fix the two ends of the second elastic member 140.

[0076] In some embodiments, Figure 1-Figure 5 As shown, the sensing member 170 can be arranged on one side of the guide channel 114, and a baffle 162 extending laterally can be provided on the side of the trigger member 160 facing the sensing member 170. During the movable stroke of the trigger member 160, the baffle 162 can stop against the sensing part of the sensing member 170 to trigger the sensing member 170.

[0077] In some embodiments, Figure 1-Figure 5 As shown, the movable member 120 may be provided with a protrusion 126 , and the trigger member 160 may be provided with a recess 161 at one end facing the movable member 120 . The protrusion 126 may rotate in the recess 161 to drive the trigger member 160 to move in the lock body 110 .

[0078] The protrusion 126 can abut against the recess 161 to push the trigger 160 to move. In one example, a protrusion 126 is provided on the side of the locking portion 121 of the movable member 120 away from the lock buckle 150. When the lock buckle 150 moves into the lock body 110, the protrusion 126 on the locking portion 121 is pushed to abut against the recess 161, and the trigger 160 is driven to move. By providing the recess 161, the movable stroke of the trigger 160 is reduced, and the volume of the lock body 110 is reduced. By providing the protrusion, the locking portion 121 is prevented from directly contacting the trigger 160, the wear of the locking portion 121 is reduced, and the durability is improved.

[0079] In one example, a convex rib may be provided on the recess 161 , and the convex rib is used to abut against the protrusion 126 to reduce friction resistance and improve durability.

[0080] In some embodiments, Figure 1-Figure 5 As shown, the recess 161 may be arranged in an arc shape, so as to reduce friction loss and improve durability when the protrusion 126 abuts against the recess 161 and rotates in the recess 161 .

[0081] Based on the same concept, an embodiment of the present application also provides an electrical device, which includes a body, a door body and a door lock 100 such as any of the above technical solutions, wherein the lock body 110 is installed on the body and the lock buckle 150 is installed on the door body.

[0082] It is understandable that because the electrical device in the present application includes the door lock 100 as in any of the above-mentioned technical solutions, the technical features and technical effects of the door lock 100 as in any of the above-mentioned technical solutions are included and will not be elaborated here.

[0083] According to the electrical device provided in the embodiment of the present application, the lock catch 150 is moved in the lock body 110 by rotating the door body. When closing the door, the door body is pushed to push the lock catch 150 into the lock body 110 to drive the movable part 120 to rotate from the initial position to the restrained position, and the first elastic member 130 can drive the movable part 120 to limit at the restrained position so that the movable part 120 locks the lock catch 150; when opening the door, the door body is pulled to drive the lock catch 150 to move outward, and the lock catch 150 drives the movable part 120 to overcome the elastic force of the first elastic member 130 to move to the initial position, and when the lock catch 150 is separated from the movable part 120, the first elastic member 130 continues to drive the movable part 120 to reset to the initial position. In this embodiment, the door lock 100 has few components, simple structure and action, small space occupation, low production and assembly difficulty, and low production cost.
