Detailed implementation manners

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] The following will, with reference to the drawings, detail the technical solutions disclosed in each embodiment of the present utility model.

[0024] As Figures 1 to 13 shown, an embodiment of the present utility model discloses a lock, and the disclosed lock includes a lock body 100, a battery box 200 and a battery cover 300.

[0025] The lock body 100 is the main component of the lock. The lock body 100 includes, but is not limited to, components such as a housing, a lock body device, and a circuit structure. The lock body 100 is provided with an installation groove 110. Specifically, the housing of the lock body 100 may be provided with an installation groove 110, and the installation groove 110 here is the battery compartment of the lock.

[0026] The battery cover 300 is movable relative to the lock body 100 to cover or expose the installation groove 110. When the battery cover 300 covers the notch of the installation groove 110, the installation groove 110 is covered and the battery compartment is closed at this time. When the battery cover 300 is removed from the installation groove 110, the installation groove 110 is exposed and the battery compartment is opened at this time. The battery cover 300 here can be directly detached from the lock body 100. Or the battery cover 300 slides to a position where it does not cover the installation groove 110. At this time, the battery cover 300 can be slidably or rotatably engaged with the lock body 100. For example, when the battery cover 300 is removed from the notch of the installation groove 110, the battery cover 300 does not detach from the lock body 100 but moves or rotates to a position where it does not cover the notch of the installation groove 110. In another solution, as Figure 1 and Figure 2 shown, the battery cover 300 can be detachably connected to the lock body 100. At this time, when the battery compartment is opened, as Figure 2 shown, the battery cover 300 is detached from the lock body 100. When the battery compartment is closed, as Figure 1 shown, the battery cover 300 is installed on the lock body 100.

[0027] The battery box 200 is rotatably connected to the lock body 100 through a rotating shaft. At this time, the battery box 200 can be rotated and switched between a first position and a second position. Optionally, a rotating shaft can be fixedly connected to the battery box 200, a mating hole can be provided on the inner wall of the installation groove 110, at least a part of the rotating shaft can be located in the mating hole, and the rotating shaft rotates around the center line of the mating hole. Of course, the rotating shaft can also be fixedly arranged on the inner wall of the installation groove 110, and the mating hole can be opened on the outer side wall of the battery box 200.

[0028] The battery box 200 is provided with a plurality of accommodating spaces 201 stacked in sequence. The stacking direction of the plurality of accommodating spaces 201 can be understood as the thickness direction of the battery box 200. Each accommodating space 201 is used to install at least one battery 700. Each accommodating space 201 has a battery disassembly and assembly port 202. The battery 700 corresponding to each accommodating space 201 is inserted into the corresponding accommodating space 201 through the battery disassembly and assembly port 202. At this time, each battery 700 can enter and exit the corresponding accommodating space 201 through the battery disassembly and assembly port 202.

[0029] When the battery box 200 is in the first position, the battery box 200 rotates towards the notch direction of the installation groove 110. At this time, the battery box 200 rotates outwards towards the installation groove 110, so that the battery disassembly and assembly ports 202 of each accommodation space 201 are opposite to the notch of the installation groove 110. At this time, the battery disassembly and assembly ports 202 corresponding to each accommodation space 201 can be exposed, so that the battery replacement operation can be performed on each accommodation space 201. Since the battery disassembly and assembly ports 202 of each accommodation space 201 are exposed through the notch of the installation groove 110, it can also be understood here that the battery 700 is rotated to the position facing the notch of the installation groove 110. Therefore, the installation groove 110 does not interfere with the battery, and thus the battery in any one of the accommodation spaces 201 can be taken out in the first position without affecting the batteries in other accommodation spaces 201. When the battery box 200 is in the second position, the battery box 200 rotates towards the bottom direction of the installation groove 110, so the battery box 200 rotates into the installation groove 110. When the battery box 200 is in the second position, the battery disassembly and assembly ports 202 of at least one accommodation space 201 face the inner wall of the installation groove 110. At this time, the inner wall of the installation groove 110 interferes with the battery 700, so the battery replacement operation of the battery 700 cannot be realized. At this time, the battery box 200 rotates towards the direction inside the accommodation groove 110, so that at least one of the battery disassembly and assembly ports 202 is blocked. At this time, the battery cannot be taken out from the blocked battery disassembly and assembly port 202.

[0030] In the lock disclosed in the present application, the battery box 200 can rotate relative to the lock body 100. Therefore, the battery disassembly and assembly ports 202 of the multiple accommodation spaces 201 of the battery box 200 can be rotated to the positions facing the notch of the installation groove 110, so that the battery disassembly and assembly ports 202 are exposed, enabling the user to replace the batteries 700 in the corresponding each accommodation space 201 separately, and thus not affecting other batteries 700. Therefore, the battery 700 of the lock can be replaced online, avoiding the risk of power failure of the lock, and thus improving the safety and reliability of the lock.

[0031] In an alternative solution, as Figure 3 and Figure 5 shown, the battery box 200 is provided with a first accommodation space and a second accommodation space which are stacked. The first accommodation space corresponds to a first battery disassembly and assembly port, and the second accommodation space corresponds to a second battery disassembly and assembly port. When the battery box 200 is in the first position, both the first battery disassembly and assembly port and the second battery disassembly and assembly port are opposite to the notch of the installation groove 110, as Figure 5As shown in the figure. At this time, the user can perform battery replacement operations on the first accommodation space and the second accommodation space separately. When the battery box 200 is in the second position, at least one of the first battery disassembly and assembly port and the second battery disassembly and assembly port faces the inner wall of the installation groove 110. As Figure 3 shown, the first accommodation space and the second accommodation space are stacked along the direction from the bottom to the opening of the installation groove 110. That is to say, the first accommodation space is close to the bottom of the installation groove 110, and the second accommodation space is close to the opening of the installation groove 110. Therefore, the first accommodation space is closer to the inner side of the accommodation groove. Therefore, when the battery box 200 is in the second position, the battery disassembly and assembly port 202 corresponding to the first accommodation space faces the inner wall of the installation groove 110, so that the inner wall of the installation groove 110 will interfere with the battery disassembly and assembly. Of course, when the depth of the installation groove 110 is small, the battery disassembly and assembly port 202 corresponding to the second accommodation space can be opposite to the opening of the installation groove 110 when the battery box 200 is in the second position.

[0032] Therefore, when the battery box 200 is in the second position, the battery in the second accommodation space can be replaced. At this time, the battery in the first accommodation space is not affected. However, if the battery in the second accommodation space needs to be replaced, the battery box 200 must be rotated to the first position to expose the battery disassembly and assembly port of the first accommodation space.

[0033] In the solution disclosed in this application, a spring piece can be provided on the lock body 100. When the battery 700 is installed in the accommodation space, the battery 700 contacts the corresponding spring piece to form an electrical connection. At this time, during the rotation of the battery box 200, the battery 700 always presses against the spring piece, so that the battery 700 and the lock body 100 always maintain an electrical connection.

[0034] Or, in another alternative solution, an electrical connection part is correspondingly provided for each accommodation space 201. The electrical connection part is electrically connected to the lock body 100 through a corresponding circuit or flexible circuit board. At this time, it can be realized that during the rotation of the battery box 200, the battery 700 and the lock body 100 always maintain an electrical connection.

[0035] Of course, the battery 700 and the lock body 100 can also be electrically connected in other ways, which are not limited herein.

[0036] In the above-mentioned embodiments, during the process of closing or opening the door, the battery box 200 is prone to the risk of rotation due to the impact force, so it is easy to collide with the battery cover 300. In addition, when replacing the battery 700, it is difficult for the battery box 200 to stay in the first position. Therefore, the user needs to hold the battery box 200 with one hand and replace the battery 700 with the other hand, so the difficulty of replacing the battery 700 is relatively large.

[0037] In another alternative embodiment, the lock may further include an elastic member 400. The elastic member 400 may be located within the installation groove 110. One end of the elastic member 400 may be connected to the battery box 200, and the other end of the elastic member 400 may be connected to the lock body 100. In the case of the first position, the force exerted by the elastic member 400 on the battery box 200 may be directed outside the installation groove 110. At this time, the battery box 200 can be held in the first position under the elastic support of the elastic member 400. In the case of the second position, the force exerted by the elastic member 400 on the battery box 200 is directed inside the installation groove 110. At this time, the battery box 200 can be held in the second position under the elastic support of the elastic member 400.

[0038] In this solution, the elastic member 400 can hold the battery box 200 in the first position or the second position, thus avoiding the risk of accidental rotation of the battery box 200, and further improving the safety of the battery box 200. At the same time, the difficulty of replacing the battery 700 is also reduced.

[0039] Optionally, the elastic member 400 may be a torsion spring. Of course, the elastic member 400 may also have other structures, which are not limited herein.

[0040] In another solution, the elastic member 400 may include a fixing ring 410 and an elastic ring body 420. At this time, the first force - applying end of the elastic ring body 420 is connected to the fixing ring 410. Here, the fixing ring 410 is connected to the battery box 200, and the second force - applying end of the elastic ring body 420 is connected to the lock body 100. At this time, depending on the position of the elastic ring body 420, the direction of the force exerted on the battery box 200 is different.

[0041] In another alternative embodiment, an elastic pressing portion 500 may be provided on the inner side wall of each receiving space 201. Each receiving space 201 may be in interference fit with its corresponding battery 700 through the elastic pressing portion 500. In this solution, the elastic pressing portion 500 can press the battery 700, thereby increasing the friction between the receiving space 201 and the battery 700, and further avoiding the risk of the battery 700 moving or falling out of the receiving space 201.

[0042] Optionally, the elastic pressing portion 500 may be an elastic structure such as a spring or a foam. Of course, the elastic pressing portion 500 may also have other structures, which are not limited herein.

[0043] In an alternative solution, each receiving space 201 may be provided with at least two elastic pressing portions 500. The at least two elastic pressing portions 500 may be located on two opposite side walls of the receiving space 201. At this time, the friction between the receiving space 201 and the battery 700 can be further increased.

[0044] In order to facilitate the user to replace the battery 700, in another alternative solution, when the battery case 200 is in the second position, a part of the battery case 200 protrudes from the mounting groove 110, and clamping areas 203 are provided on the opposite side walls of the part of the battery case 200 protruding outside the mounting groove 110. At this time, the user can drive the battery case 200 to rotate through the clamping areas 203 on the side walls on both sides.

[0045] In this solution, a part of the battery case 200 protrudes from the mounting groove 110. Therefore, there is a relatively large space for the user to drive and operate the battery case 200, thus avoiding the risk of the user's fingers slipping with the battery case 200, and making it more convenient for the user to replace the battery 700.

[0046] Optionally, the clamping area 203 can be provided with an anti-friction pad to increase the friction between the user's fingers and the clamping area 203 and avoid the risk of slipping. Alternatively, the clamping area 203 can also be provided with structures such as knurling and tooth patterns to avoid the risk of the user slipping with the clamping area 203.

[0047] In an alternative embodiment, the battery case 200 can include a first plate body 210, a second plate body 220, a third plate body 230, a fourth plate body 240, and at least one partition plate 250. The first plate body 210, the second plate body 220, the third plate body 230, and the fourth plate body 240 are sequentially connected end to end to form an enclosed space. The first plate body 210 can be disposed opposite to the third plate body 230, and the second plate body 220 and the fourth plate body 240 are disposed opposite to each other. The first plate body 210 can face the side where the mounting groove 110 opens, and the third plate body 230 can face the side of the bottom of the mounting groove 110. At least one of the second plate body 220 and the fourth plate body 240 can be rotatably connected to the lock body 100. At least one partition plate 250 can be located in the enclosed space and divide the enclosed space into at least two accommodation spaces 201.

[0048] In this solution, the structure of the battery case 200 is simple, thus reducing the manufacturing cost of the battery case 200.

[0049] In the above solution, when there is one partition plate 250, the partition plate 250 divides the enclosed space into the above-mentioned first accommodation space and second accommodation space. Specifically, the space between the first plate body 210 and the partition plate 250 is the above-mentioned second accommodation space, and the space between the third plate body 230 and the partition plate is the above-mentioned first accommodation space.

[0050] The elastic pressing parts 500 in the above solution can be respectively provided on the second plate body 220 and the fourth plate body 240.

[0051] Further, a limiting convex portion 251 may be provided at one end of the partition plate 250 facing the battery disassembly and assembly port 202. The limiting convex portion 251 can be used for limiting cooperation with the battery in a direction outside the accommodation space 201. In this solution, the limiting convex portion 251 can prevent the battery 700 from shifting, thereby improving the assembly reliability of the battery 700. In addition, when the battery case 200 is switched from the second position to the first position, since the limiting convex portion 251 does not move, the battery 700 rotates with the battery case 200. During the rotation of the battery, the limiting convex portion 251 will push the battery to move a certain distance in the direction towards the accommodation space 201. At this time, the electrical connection structure between the battery and the lock body 100 will become loose, so it is more convenient to disassemble the battery.

[0052] In the above embodiment, the multiple battery disassembly and assembly ports 202 may be distributed on different sides of the battery case 200. At this time, due to the different interference positions between the multiple battery disassembly and assembly ports 202 and the installation groove 110, the battery case 200 needs to rotate a large angle, thereby increasing the rotation difficulty of the battery case 200.

[0053] Based on this, in another alternative embodiment, all the battery disassembly and assembly ports 202 are located on the same side of the battery case 200. In this solution, the multiple battery disassembly and assembly ports 202 interfere with the same side of the installation groove 110. Therefore, as long as the lowest-side battery disassembly and assembly port 202 is avoided, the rotation angle of the battery case 200 is reduced, thereby reducing the rotation difficulty of the battery case 200.

[0054] In another alternative solution, the lock body 100 may further include a disassembly switch 600. The battery cover 300 and the lock body 100 can be detachably connected through the disassembly switch 600. The disassembly switch 600 may include a button 610, a first clamping portion 620, a second clamping portion 630, and an elastic reset portion 640. The button 610 is fixedly connected to the first clamping portion 620, and the second clamping portion 630 is fixedly connected to the lock body 100. The button 610 can be elastically connected to the battery cover 300 through the elastic reset portion 640. The button 610 is used to drive the first clamping portion 620 to move relative to the second clamping portion 630, so that the first clamping portion 620 and the second clamping portion 630 are clamped or separated.

[0055] The first clamping portion 620 has a first state and a second state. The button 610 can drive the first clamping portion 620 to switch between the first state and the second state. When the first clamping portion 620 is in the first state, the first clamping portion 620 and the second clamping portion 630 can be clamped to each other, so that the battery cover 300 and the lock body 100 are connected. When the first clamping portion 620 is in the second state, the first clamping portion 620 and the second clamping portion 630 can be separated from each other, so that the battery cover 300 and the lock body 100 can be separated.

[0056] During the specific operation process, when the user presses the button 610 to compress the elastic reset part 640, the elastic reset part 640 shortens. At this time, the first engaging part 620 moves away from the second engaging part 630. When the user removes the pressure on the button 610, the elastic reset part 640 resets and elongates, so the first engaging part 620 moves closer to the second engaging part 630.

[0057] In this solution, during the process of disassembling and installing the battery cover 300 and the lock body 100, there is no need to apply a large force to the battery cover 300 and the lock body 100. Only by driving the first engaging part 620 to move with the button 610 can the separation of the first engaging part 620 and the second engaging part 630 be achieved. Therefore, the disassembly difficulty is relatively small. At the same time, there is no need to apply a large force between the battery cover 300 and the lock body 100, so it is less likely to damage the battery cover 300 and the lock body 100, thus reducing the disassembly difficulty of the battery cover 300 and the lock body 100.

[0058] In another alternative embodiment, one of the battery cover 300 and the lock body 100 is provided with a positioning convex part 301, and the other is provided with a positioning groove. The battery cover 300 and the lock body 100 are positioned and matched through the positioning convex part 301 and the positioning groove. In this solution, the positioning convex part 301 and the positioning groove can position the installation positions of the battery cover 300 and the lock body 100, thereby improving the assembly accuracy and efficiency of the battery cover 300 and the lock body 100. In addition, the positioning convex part 301 and the positioning groove can also assist in limiting multiple degrees of freedom, thereby simplifying the structures of the first engaging part 620 and the second engaging part 630.

[0059] In one solution, as Figure 2 shown, the battery cover 300 can be installed at the corresponding position of the lock body 100 in the direction from bottom to top. At this time, the positioning convex part 301 and the positioning groove cooperate with each other. The positioning convex part 301 and the positioning groove can limit the degrees of freedom of the battery cover 300 relative to the lock body 100 in five directions: front, back, left, right, and up. At this time, only the freedom in the lower direction is not restricted. Therefore, when disassembling the switch 600, only the freedom in the lower direction needs to be restricted, so the structures of the first engaging part 620 and the second engaging part 630 can be simplified.

[0060] Furthermore, the button 610 can be provided with a guide rod 611, and the battery cover 300 can be provided with a guide hole 302. The guide rod 611 can extend into the guide hole 302, and the button 610 and the battery cover 300 can be guided and matched through the guide rod and the guide hole 302. In this solution, the guide rod 611 and the guide hole 302 can limit the moving position of the button 610, thereby avoiding the risk of skew and jamming during installation.

[0061] The above-mentioned guide rod 611 and the elastic reset portion 640 can be arranged in parallel. Alternatively, the elastic reset portion 640 can also be sleeved on the guide rod 611. The specific positional relationship between the guide rod 611 and the elastic reset portion 640 is not limited.

[0062] In another alternative solution, the button 610 can be provided with a first limiting buckle 612, and the battery cover 300 can be provided with a second limiting buckle 303. The first limiting buckle 612 and the second limiting buckle 303 can be in limiting cooperation along the elongation direction of the elastic reset portion 640. This solution can limit the button 610, thereby avoiding the risk of the button 610 falling off.

[0063] Optionally, the second limiting buckle 303 can be a clamping hole. The first limiting buckle 612 passes through the clamping hole, and the first limiting buckle 612 can move along the axis direction of the clamping hole. When the first clamping portion 620 is in the first state, at this time, the buckle of the first limiting buckle 612 is in limiting cooperation with the edge of the clamping hole, thereby restricting the button 610 on the battery cover 300 and avoiding the risk of the button 610 detaching from the battery cover 300.

[0064] In another alternative solution, the battery cover 300 can include a main body portion 310 and a decorative plate 320. The main body portion 310 can be elastically connected to the button 610 through the elastic reset portion 640; the decorative plate 320 and the button 610 can be on the same side of the main body portion 310. The decorative plate 320 is connected to the main body portion 310, and the decorative plate 320 can be provided with an avoidance notch 321, and the button 610 can be located within the avoidance notch 321.
