[0015] Compared with the prior art, the housing structure and door lock of the embodiment of the utility model have the following beneficial effects:

[0016] The bracket assembly and the main body are slidably matched through the slide groove. When the bracket assembly moves to the locking position, the first stop structure and the second stop structure are opposite to each other to limit the movement of the bracket assembly along the thickness direction of the main body. At this time, the spring sheet elastically abuts against the limit baffle to limit the sliding of the bracket assembly. In the process of the bracket assembly moving along the slide groove to the locking position, the spring sheet is first deformed by force to allow the bracket assembly to continue to move to the locking position. Then, after the bracket assembly reaches the locking position, the spring sheet recovers its deformation and elastically abuts against the limit baffle to limit the bracket assembly and the main body from continuing to slide relative to each other. The bracket assembly and the main body are locked together through the relative first stop structure and the second stop structure. At this time, the battery or other electronic device is placed in the main body and covered by the bracket assembly, so that the user cannot access the battery or other electronic device.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The present embodiment provides a door lock 100 , which includes a battery 20 and a shell structure 10 . The battery 20 is disposed in a main body 12 of the shell structure 10 . The battery 20 can be accessed only by disassembling the shell structure 10 , so that a user can replace the battery 20 .

[0036] The shell structure 10 includes a main body 12, a bracket assembly 14 and a spring 16. The main body 12 is provided with a slide groove 121, and the main body 12 is provided with a first stop structure 122 on the side wall forming the slide groove 121; the bracket assembly 14 is provided with a second stop structure 141, and the bracket assembly 14 is slidably matched with the slide groove 121, and the bracket assembly 14 can slide along the slide groove 121 to move to a locked position or an unlocked position. When the bracket assembly 14 is in the locked position, the bracket assembly 14 and the main body 12 are locked together, and the user cannot access the battery 20; when the bracket assembly 14 is in the unlocked position, the bracket assembly 14 and the main body 12 can be separated, and the user can access the battery 20 in the main body 12, so that the user can replace the battery 20. When the bracket assembly 14 moves to the locked position, the second stop structure 141 and the first stop structure 122 are opposite to each other to limit the bracket assembly 14 from moving along the thickness direction of the main body 12. The thickness direction of the main body 12 is the direction in which the bracket assembly 14 and the main body 12 are separated, and the thickness direction of the main body 12 is perpendicular to the sliding direction of the bracket assembly 14. One of the bracket assembly 14 and the main body 12 is connected with the spring sheet 16, and the other of the bracket assembly 14 and the main body 12 is provided with a limit stop plate 124. When the bracket assembly 14 moves to the locked position, the spring sheet 16 abuts against the limit stop plate 124 to limit the bracket assembly 14 from sliding further. The spring sheet 16 is elastic and can be a steel sheet with a free end or a plastic sheet with a free end. The free end of the steel sheet or the plastic sheet can be deformed after being subjected to force, so that the spring sheet 16 is separated from the limit stop plate 124, thereby releasing the limit of the bracket assembly 14 and the main body 12 in the sliding direction.

[0037] In this embodiment, the bracket assembly 14 and the main body 12 are slidably matched through the slide groove 121. When the bracket assembly 14 moves to the locked position, the first stop structure 122 and the second stop structure 141 are opposite to each other to limit the movement of the bracket assembly 14 along the thickness direction of the main body 12. At this time, the spring sheet 16 elastically abuts against the limit baffle 124 to limit the sliding of the bracket assembly 14. In the process of the bracket assembly 14 moving to the locked position along the slide groove 121, the spring sheet 16 is first deformed by force to allow the bracket assembly 14 to continue to move to the locked position. Then, after the bracket assembly 14 reaches the locked position, the spring sheet 16 restores its deformation and elastically abuts against the limit baffle 124 to lock the bracket assembly 14 and the main body 12 together. At this time, the battery 20 or other electronic devices are placed in the main body 12 and covered by the bracket assembly 14, so that the user cannot touch the battery 20 or other electronic devices. When the battery 20 or other electronic devices need to be replaced, an external force moves the spring piece 16, causing the spring piece 16 to deform and separate from the limit baffle 124, pushing the bracket assembly 14 to slide relative to the main body 12 until the first stop structure 122 and the second stop structure 141 are no longer opposite each other. The bracket assembly 14 can be separated from the main body 12, so that the user can access the battery 20 or other electronic devices. In the process of separating the bracket assembly 14 from the main body 12, the user does not need to use professional tools, but only needs to move the spring piece 16 to separate the spring piece 16 from the limit baffle 124, thereby facilitating the replacement procedure of the battery 20 or other electronic devices. With this structural method, the user can easily separate the main body 12 and the bracket assembly 14 with bare hands without the help of tools, saving time and effort, and bringing great convenience to the user.

[0038] In one embodiment, the spring 16 includes a fixing portion 161, a bending portion 162 and an extending portion 163 connected in sequence. The fixing portion 161 is connected to the bracket assembly 14, or the fixing portion 161 is connected to the main body 12. Figure 6 The fixing portion 161 is connected to the bracket assembly 14. The bent portion 162 is used to abut against the limit baffle 124, and the bent portion 162 is bent and extended toward the limit baffle 124. The bent portion 162 can be in a bent shape, and the extension portion 163 forms a free end, and the extension portion 163 extends toward the outside of the main body 12. The extension portion 163 is used to receive an external force to drive the bent portion 162 to separate from the limit baffle 124. In this embodiment, the fixing portion 161 is used to fix the spring piece 16 on the main body 12 or the bracket assembly 14, the bending portion 162 is used to provide elastic force and elastically abut the limit baffle 124 to limit the relative sliding of the bracket assembly 14 and the main body 12, and the extending portion 163 is used to receive the external force to drive the bending portion 162 to deform to break away from the abutment of the limit baffle 124. The fixing portion 161, the bending portion 162 and the extending portion 163 are an integrated structure, each playing its own role, and the structure is simple, stable and reliable, and does not require an independent connecting structure to connect them together.

[0039] In one embodiment, the main body 12 is provided with a notch 101 at the position of the extension 163, and the notch 101 is used to expose the extension 163. The user can touch the extension 163 by passing through the notch 101 with a finger or a stick-shaped tool, so that the user can easily touch the extension 163 to conveniently separate the bracket assembly 14 from the main body 12. In another embodiment, the bracket assembly 14 is provided with a notch 101 at the position of the extension 163, and the notch 101 is used to expose the extension 163. The user can touch the extension 163 by passing through the notch 101 with a finger or a stick-shaped tool, so that the user can easily touch the extension 163 to conveniently separate the bracket assembly 14 from the main body 12. In another embodiment, both the main body 12 and the bracket assembly 14 are provided with a notch 101 at the position of the extension portion 163, and the notches 101 of the two correspond to each other. The notch 101 is used to expose the extension portion 163. The user can touch the extension portion 163 by passing a finger or a stick-like tool through the notch 101, thereby facilitating the user to contact the extension portion 163 to conveniently separate the bracket assembly 14 and the main body 12.

[0040] In one embodiment, the bracket assembly 14 includes a bracket 146 and an elastic pad 147. The bracket 146 is provided with a second stop structure 141 and a fixing structure 148. The fixing structure 148 is used to fix the bracket 146 to an external structure. The fixing structure 148 may be a structure with rivets, a structure with screws, or a structure with nails. The external structure may be a wall, a door, etc. The elastic pad 147 is provided on a side of the bracket 146 away from the main body 12. The material of the elastic pad 147 may be silicone or foam. In this embodiment, when the bracket 146 is fixed to the external structure by the fixing structure 148, the elastic pad 147 is between the bracket 146 and the external structure. As the fixing structure 148 is tightened, the bracket 146 will gradually move closer to the external structure, thereby squeezing the elastic pad 147. The elastic pad 147 is deformed and filled between the bracket 146 and the external structure, thereby filling the gap between the bracket 146 and the external structure, thereby improving the stability and sealing of the shell structure 10.

[0043] In one embodiment, a through groove 142 is provided on the side of the bracket assembly 14, and the side of the bracket assembly 14 is located on the side of the bracket assembly 14 in the width direction Z or the length direction X. The through groove 142 penetrates the bracket assembly 14 along the thickness direction Y of the bracket assembly 14, and the through groove 142 is used for the first stop structure 122 to be inserted, and the second stop structure 141 is located in the through groove 142. After the first stop structure 122 is inserted into the through groove 142, the first stop structure 122 and the second stop structure 141 are misaligned in the thickness direction of the main body 12. In the process of the bracket assembly 14 moving to the locking position, the first stop structure 122 gradually moves in the through groove 142 to be opposite to the second stop structure 141, that is, the first stop structure 122 and the second stop structure 141 overlap in the thickness direction of the main body 12. During the assembly process, the bracket assembly 14 first moves along its thickness direction Y, the first stop structure 122 is inserted into the through groove 142, and the bracket assembly 14 then slides along its length direction X until the first stop structure 122 and the second stop structure 141 are opposite to each other, so that the bracket assembly 14 reaches the locking position. In this embodiment, by providing the through groove 142, the sliding track of the bracket assembly 14 is optimized, and the single directional sliding of the bracket assembly 14 is converted into sliding in its thickness direction and length direction, thereby shortening the sliding distance of the bracket assembly 14 in its length direction. In addition, the through groove 142 can accommodate the first stop structure 122, thereby limiting the first stop structure 122, ensuring that the first stop structure 122 moves within the range of the through groove 142, reducing the range of motion of the bracket assembly 14, and facilitating the user to assemble the bracket assembly 14 and the main body 12 together.

[0044] Optionally, a first inclined surface structure 123 is provided on the side of the first stop structure 122 away from the second stop structure 141. The first inclined surface structure 123 is used to guide the second stop structure 141 when the bracket assembly 14 is assembled. The first inclined surface structure 123 can be a flat inclined surface or an arc inclined surface. During the movement of the second stop structure 141, the second stop structure 141 and the first inclined surface structure 123 are in contact, thereby playing a guiding role.

[0045] Optionally, a second inclined surface structure 143 is provided on the side of the second stop structure 141 away from the first stop structure 122. The second inclined surface structure 143 is used to guide the first stop structure 122 when the bracket assembly 14 is assembled. The second inclined surface structure 143 can be a flat inclined surface or an arc inclined surface. During the movement of the second stop structure 141, the second inclined surface structure 143 contacts the first stop structure 122, thereby playing a guiding role.

[0046] Optionally, a third inclined surface structure 144 is provided on the second surface of the through groove 142, and the third inclined surface structure 144 is used to guide the first stop structure 122 when the bracket assembly 14 is assembled. The third inclined surface structure 144 can be a flat inclined surface or an arc inclined surface. During the movement of the second stop structure 141, the first stop structure 122 and the third inclined surface structure 144 are in contact, thereby playing a guiding role.

[0047] In one embodiment, the sliding direction perpendicular to the support assembly 14 (and Figure 2 In the Z direction shown in the figure, the side of the bracket assembly 14 includes a first side portion 127 and a second side portion 128 which are arranged opposite to each other. The first side portion 127 and the second side portion 128 are both provided with a through slot 142 and a second stop structure 141. The main body 12 is provided with a first stop structure 122 at positions corresponding to the through slot 142. In this embodiment, the bracket assembly 14 is locked in the sliding direction by the spring sheet 16. In the sliding direction perpendicular to the bracket assembly 14, the first side portion 127 and the second side portion 128 which are arranged opposite to each other are both provided with a second stop structure 141 which cooperates with the first stop structure 122. When the first stop structure 122 and the second stop structure 141 cooperate, the bracket assembly 14 is locked perpendicular to its sliding direction. At this point, the bracket assembly 14 is locked in both its sliding direction and the direction perpendicular to its sliding direction. Therefore, the bracket assembly 14 is stably locked and there is no shaking of the bracket assembly 14.

[0048] When the bracket assembly 14 moves to the locked position, the bracket assembly 14 abuts against the wall of the slide groove 121 in the sliding direction. Figure 2 The groove wall of the slide groove 121 and the spring sheet 16 together lock the bracket assembly 14 in the sliding direction of the bracket assembly 14. Compared with the arrangement of spring sheets 16 on both sides of the front and rear sides of the bracket assembly 14 in the sliding direction, it is only necessary to move the spring sheet 16 in one direction, and the disassembly and assembly of the bracket assembly 14 are simpler.

[0049] In one embodiment, a third stop structure 126 is provided on the groove wall of the slide groove 121, and the third stop structure 126 is located in the sliding direction of the bracket assembly 14. The third stop structure 126 is located on the third side portion 125, and the bracket assembly 14 is provided with a fourth stop structure 145, and the fourth stop structure 145 is located in the sliding direction of the bracket assembly 14, wherein when the bracket assembly 14 moves to the locking position, the fourth stop structure 145 and the third stop structure 126 are opposite to each other along the thickness direction of the main body 12 to limit the movement of the bracket assembly 14 along the thickness direction of the main body 12. The matching structure of the third stop structure 126 and the fourth stop structure 145 and the matching structure of the first stop structure 122 and the second stop structure 141 are respectively located in different directions, so as to limit the bracket assembly 14 from different directions and increase the connection strength between the bracket assembly 14 and the main body 12.

[0050] In one embodiment, the first stop structure 122 is provided with one of a convex bump and a matching groove on the side facing the second stop structure 141, and the second stop structure 141 is provided with the other of a convex bump and a matching groove on the side facing the first stop structure 122, and the convex bump is used to match with the matching groove. When the second stop structure 141 slides to face the first stop structure 122, the convex bump is embedded in the matching groove, thereby preventing the second stop structure 141 from moving further. At this time, the matching of the convex bump and the matching groove plays a positioning role. During use, the convex bump and the matching groove can also prevent the second stop structure 141 from shaking relative to the first stop structure 122.

[0051] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or may be indirectly connected to the other element through an intermediate element.
