Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle-mounted equipment technology, and more specifically, to a locking mechanism and a storage device. Background Technology
[0002] Existing sliding storage devices generally open or close by moving sliding doors or drawers. Some of these devices use motors without self-locking functions to drive the sliding doors or drawers. When the storage device is closed, if the sliding door or drawer is subjected to an accelerating impact or a large external force that causes it to open, the force on the sliding door or drawer will be converted into a reverse driving force of the motor, thus causing the closed state of the storage device to fail.

Detailed Implementation
[0057] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0058] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0059] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0060] In the description of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0061] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0062] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0063] As disclosed in the background section, some storage devices use motors without self-locking functions to drive sliding doors or drawers. When the storage device is closed, if the sliding door or drawer is subjected to an accelerating impact or a large external force that causes it to open, the force on the sliding door or drawer will be converted into a reverse driving force of the motor, thereby causing the storage device to change from a closed state to an open state. In other words, the storage device cannot be stably kept in a closed state. The embodiments of this application provide a storage device that at least solves the above-mentioned technical problems.
[0064] Please refer to Figure 1 , Figure 2 The storage device 10 provided in the embodiments of this application includes a locking mechanism. The locking mechanism includes an installation body, a movable component 200, and a drive mechanism 300. The installation body has a storage opening. The drive mechanism 300 is disposed on the installation body and is connected to the movable component 200 to drive the movable component 200 to move. The movable component 200 is used to close or open the storage opening during the movement and locks itself to the installation body when the storage opening is closed.
[0065] In the embodiments of this application, the drive mechanism 300 includes a motor 310 and a cable mechanism 320 connected to the motor 310, and the cable mechanism 320 is connected to the movable component 200.
[0066] It should be noted that the motor 310 does not have a self-locking function, and the motor 310 drives the movable component 200 to move through the cable mechanism 320.
[0067] During the movement of the movable component 200 under the drive of the drive mechanism 300, it can close the storage opening and lock itself to the mounting body while the storage opening is closed; during the reverse movement of the movable component 200 under the drive of the drive mechanism 300, it can unlock itself from the mounting body and open the storage opening.
[0068] When in use, the storage device 10 uses a motor 310 to drive the movable component 200 to move via a cable mechanism 320, so that the movable component 200 closes the storage opening and locks the movable component 200 to the mounting body in the closed storage opening state. If the movable component 200 is subjected to an accelerating impact or a large external force that would cause it to open, it is not easy to move relative to the mounting body, thereby enabling the storage device 10 to remain stably closed.
[0069] In some embodiments, the movable component 200 includes a movable support 210, a slider 220, and a closing member 400 connected to the movable support 210. The movable support 210 is movably disposed on the mounting body, and the slider 220 is movably disposed on the movable support 210. The driving mechanism 300 is connected to the slider 220 to drive the slider 220 to move. The slider 220 is used to drive the movable support 210 to move during the movement. The closing member 400 moves synchronously with the movable support 210. The closing member 400 is used to close or open the storage opening during the movement. The movable support 210 can be locked to the mounting body when the closing member 400 closes the storage opening.
[0070] The closure 400 is a sliding door or drawer. The movable bracket 210 is integrally formed with the closure 400, or the movable bracket 210 and the closure 400 are fixedly connected by bolts or other fasteners. The mounting body includes a guide rail 100, a motor 310 is fixed to the guide rail 100 via a motor bracket 311, the movable bracket 210 is movably mounted on the guide rail 100, and the sliding member 220 is movably mounted on the movable bracket 210. It can be understood that the mounting body also includes a housing for mounting the locking mechanism, and the storage opening is located on the housing.
[0071] Please see Figure 3 In some embodiments, the guide rail 100 is provided with a first sliding groove 110, and the movable bracket 210 is provided with a first sliding part 211 that slides in cooperation with the first sliding groove 110; of course, in other embodiments, the movable bracket 210 is provided with a first sliding groove 110, and the guide rail 100 is provided with a first sliding part 211 that slides in cooperation with the first sliding groove 110, so that the movable bracket 210 can move relative to the guide rail 100.
[0072] Please see Figure 4 , Figure 5In some embodiments, the movable support 210 is provided with a second sliding groove 212, and the sliding member 220 is provided with a second sliding portion 221 that slides in conjunction with the second sliding groove 212. In other embodiments, the sliding member 220 is provided with a second sliding groove 212, and the movable support 210 is provided with a second sliding portion 221 that slides in conjunction with the second sliding groove 212, thereby enabling the sliding member 220 to move relative to the movable support 210. The number of second sliding portions 221 can be two, and correspondingly, the number of second sliding grooves 212 is also two, with each of the two second sliding portions 221 sliding in conjunction with one of the two second sliding grooves 212.
[0073] The cable mechanism 320 includes a winding drum 321, a cable 322, and two guide wheels 323. Two guide wheel supports 130 are provided at both ends of the guide rail 100. The two guide wheels 323 are rotatably mounted on the two guide wheel supports 130 via two guide wheel shafts 3231. The winding drum 321 is rotatably connected to the guide rail 100. The motor 310 is keyed to the winding drum 321. The cable 322 is wound around both the winding drum 321 and the two guide wheels 323. The sliding member 220 is provided with two first mounting grooves 222 and two cable grooves 224 that are respectively connected to the two first mounting grooves 222. The two ends of the cable 322 pass through the corresponding cable grooves 224 and are respectively inserted into the two first mounting grooves 222. The two ends of the cable 322 are tensioned by preload springs 324.
[0074] When the motor 310 starts, the motor 310 drives the winding drum 321 to rotate, the winding drum 321 drives the cable 322 to move, thereby driving the sliding member 220 to move. During the movement, the sliding member 220 can resist and push the movable bracket 210 to move. The sliding door or drawer can close or open the storage opening during the movement of the movable bracket 210. Furthermore, the movable bracket 210 can be locked to the mounting body when the sliding door or drawer closes the storage opening.
[0075] In the embodiments of this application, the movable bracket 210 has a first limit position and a second limit position during the movement. When the movable bracket 210 is in the first limit position, the sliding member 220 can move relative to the movable bracket 210 so that the movable bracket 210 is locked to the mounting body. When the movable bracket 210 is not in the first limit position, the sliding member 220 and the movable bracket 210 remain relatively stationary.
[0076] Please refer to Figures 6-8 In some embodiments, a locking member 213 is movably provided on the movable bracket 210, and the sliding member 220 is used to drive the locking member 213 to move during the movement of relative to the movable bracket 210, thereby locking the movable bracket 210 to the mounting body or unlocking the movable bracket 210 from the mounting body.
[0077] The locking member 213 is movably mounted on the movable bracket 210. The locking member 213 is provided with a locking part 2134, and the guide rail 100 is provided with a locking engagement part 120 that cooperates with the locking part 2134. The locking engagement part 120 can be a lock hole or a locking groove.
[0078] The locking member 213 moves under the drive of the sliding member 220, and during the movement, it cooperates with the locking engagement part 120 or disengages from the locking engagement part 120.
[0079] Please refer to Figure 5 and Figure 9 The sliding member 220 is provided with a first guide structure, and the locking member 213 is provided with a guide part 2131 that cooperates with the first guide structure. The guide part 2131 is used to move relative to the first guide structure during the movement of the sliding member 220 relative to the movable bracket 210, so that the locking member 213 moves relative to the movable bracket 210.
[0080] In an optional embodiment, the first guide structure is a first guide groove 223, and the guide portion 2131 is a shaft pin that protrudes from the surface of the locking member 213. During the movement of the sliding member 220, the guide portion 2131 moves within the first guide groove 223, causing the locking member 213 to move relative to the movable bracket 210 to achieve locking or unlocking.
[0081] In another optional embodiment, the first guide groove 223 is formed on the locking member 213, and the guide part 2131 is disposed on the sliding member 220. As long as the guide part 2131 can move relative to the movable bracket 210 during the movement of the first guide groove 223, it is acceptable.
[0082] In other alternative embodiments, the first guide structure and the guide portion 2131 are respectively provided with mutually cooperating inclined surfaces, and the first guide structure and the guide portion 2131 achieve relative movement through the cooperation of the inclined surfaces.
[0083] Furthermore, the extension direction of at least a portion of the first guide groove 223 is set at an angle to the moving direction of the slider 220.
[0084] Please refer to Figure 10 , Figure 11 In an optional embodiment, the first guide groove 223 includes an inclined section 2231 and a first horizontal section 2232 connected to each other. The extension direction of the inclined section 2231 is set at an angle to the moving direction of the slider 220, and the extension direction of the first horizontal section 2232 is consistent with the moving direction of the slider 220.
[0085] During the movement of the slider 220, as the guide portion 2131 moves from the inclined section 2231 of the first guide groove 223 toward the first horizontal section 2232, the locking member 213 moves relative to the movable bracket 210 toward the locking engagement portion 120 until the guide portion 2131 is located at the first horizontal section 2232, at which point the locking member 213 engages with the locking engagement portion 120 to achieve locking. Conversely, as the guide portion 2131 moves from the first horizontal section 2232 of the first guide groove 223 toward the inclined section 2231, the locking member 213 moves relative to the movable bracket 210 away from the locking engagement portion 120 until the guide portion 2131 is located at a position where the inclined section 2231 is far from the first horizontal section 2232, at which point the locking member 213 disengages from the locking engagement portion 120 to achieve unlocking. The first horizontal section 2232 allows the locking member 213 to remain stably in the locked state.
[0086] In other alternative embodiments, the extension direction of the first guide groove 223 is set at an angle to the moving direction of the slider 220, and the locking member 213 moves relative to the movable bracket 210 during the movement of the guide part 2131 in the first guide groove 223.
[0087] Please refer to Figure 1 and Figure 4 In some embodiments, the movable support 210 is provided with a first elastic reset member 201, which abuts against the sliding member 220. When the movable support 210 is in a first extreme position, the first elastic reset member 201 can be compressed to allow the sliding member 220 and the movable support 210 to move relative to each other. When the movable support 210 is not in the first extreme position, the first elastic reset member 201 can keep the sliding member 220 and the movable support 210 relatively stationary.
[0088] The movable bracket 210 is provided with a first abutting surface 2181 and a second abutting surface 2191 along the moving direction of the sliding member 220. When the sliding member 220 moves toward the first abutting surface 2181, it drives the locking member 213 to move so that the movable bracket 210 is locked to the mounting body. When the sliding member 220 moves toward the second abutting surface 2191, it drives the locking member 213 to move so that the movable bracket 210 is unlocked from the mounting body.
[0089] The movable bracket 210 is provided with a first protrusion 218 and a second protrusion 219 opposite to each other along the moving direction of the slider 220. The first abutting surface 2181 and the second abutting surface 2191 are two opposing surfaces of the first protrusion 218 and the second protrusion 219, respectively. The first elastic reset member 201 is provided on the first protrusion 218. The first elastic reset member 201 can be selected as an elastic reset member such as a spring or a spring sheet. The first elastic reset member 201 abuts against the slider 220, so that the slider 220 always has a tendency to move toward the second abutting surface 2191.
[0090] In the process of using the cable 322 to move the slider 220 to close or open the sliding door or drawer, the movement of the slider 220 can drive the movable bracket 210 to move synchronously due to the presence of the first elastic reset member 201.
[0091] When the sliding door or drawer is closed, the cable 322 continues to drive the sliding member 220 to move. The sliding member 220 will move toward the first abutment surface 2181 and, during the movement, will drive the locking member 213 to lock onto the locking engagement part 120 on the mounting body. During this process, the sliding member 220 moves relative to the movable bracket 210, and the first elastic reset member 201 is compressed and deformed.
[0092] When it is necessary to open the sliding door or drawer, the pull cable 322 drives the sliding member 220 to move in the opposite direction. The sliding member 220 will move toward the second abutment surface 2191, and in the process of moving, it will drive the locking member 213 to disengage from the locking engagement part 120 on the mounting body. During this process, the sliding member 220 moves relative to the movable bracket 210, and the deformation of the first elastic reset member 201 gradually recovers.
[0093] In an optional embodiment, the first elastic reset member 201 is a spring, and a receiving groove 2182 is provided on the first abutment surface 2181 of the first protrusion 218. The spring part is located in the receiving groove 2182, one end of the spring abuts against the inner bottom wall of the receiving groove 2182, and the other end of the spring abuts against the surface of the slider 220 facing the first abutment surface 2181.
[0094] When the sliding door or drawer is closed, the cable 322 continues to drive the sliding member 220 to move. During this process, the sliding member 220 moves relative to the movable bracket 210 toward the first abutment surface 2181, and the spring is compressed and deformed until the sliding member 220 abuts against the first abutment surface 2181, and the spring is completely located in the receiving groove 2182.
[0095] When it is necessary to open the sliding door or drawer, the pull cable 322 drives the sliding member 220 to move in the opposite direction. During this process, the sliding member 220 moves relative to the movable bracket 210 toward the second abutment surface 2191, and the deformation of the spring gradually recovers until the sliding member 220 abuts against the second abutment surface 2191. At this time, the pull cable 322 can simultaneously move the sliding member 220 and the movable bracket 210 in the opposite direction.
[0096] In some embodiments, the locking member 213 is movably disposed on the movable bracket 210, and the locking member 213 is used to lock to the mounting body or release from the mounting body during movement.
[0097] The locking member 213 is movably mounted on the movable bracket 210, and the moving direction of the locking member 213 is perpendicular to the moving direction of the sliding member 220.
[0098] During the movement of the slider 220, the guide part 2131 moves relative to the first guide structure, causing the locking part 213 to move relative to the movable bracket 210 to achieve locking or unlocking.
[0099] One of the movable bracket 210 and the locking member 213 is provided with a second guide structure, and the other of the movable bracket 210 and the locking member 213 is provided with a mating structure that cooperates with the second guide structure, so that the movable bracket 210 and the locking member 213 slide in cooperation.
[0100] Please refer to Figure 4 In an optional embodiment, the second guide structure is a second guide groove 214, which is formed on the movable bracket 210. The extension direction of the second guide groove 214 is perpendicular to the movement direction of the slider 220. The mating structure on the locking member 213 is slidably mated with the second guide groove 214, so that the locking member 213 can move along the extension direction of the second guide groove 214. This mating structure can be a slider. Of course, in other embodiments, the locking member 213 itself can also be slidably mated with the second guide groove 214.
[0101] In another optional embodiment, the second guide groove 214 is formed in the locking member 213, and the movable bracket 210 is provided with a guide block that slides with the second guide groove 214, so that the locking member 213 can move along the extension direction of the second guide groove 214.
[0102] Please refer to Figures 12-14 In some embodiments, the locking member 213 is rotatably disposed on the movable bracket 210, and the locking member 213 is used to lock to the mounting body or release from the mounting body during rotation.
[0103] The locking member 213 is rotatably mounted on the movable bracket 210. During the movement of the sliding member 220, the guide part 2131 moves relative to the first guide structure, causing the locking member 213 to rotate relative to the movable bracket 210 to achieve locking or unlocking.
[0104] One of the movable bracket 210 and the locking member 213 is provided with a rotating shaft 215, and the other of the movable bracket 210 and the locking member 213 is provided with a shaft hole 2132, and the rotating shaft 215 cooperates with the shaft hole 2132.
[0105] In an optional embodiment, the movable bracket 210 is provided with a rotating shaft 215, and the locking member 213 is provided with a shaft hole 2132. The rotating shaft 215 on the movable bracket 210 cooperates with the shaft hole 2132 on the locking member 213, so that the locking member 213 can rotate relative to the movable bracket 210.
[0106] In another optional embodiment, the locking member 213 is provided with a rotating shaft 215, and the movable bracket 210 is provided with a shaft hole 2132. The rotating shaft 215 on the locking member 213 cooperates with the shaft hole 2132 on the movable bracket 210, so that the locking member 213 can rotate relative to the movable bracket 210.
[0107] In some embodiments, the movable bracket 210 is provided with a second elastic reset member 216, which is connected to the locking member 213 so that the locking member 213 has a tendency to release from the mounting body.
[0108] The second elastic reset member 216 can be a spring, a spring sheet, or other elastic reset member. By connecting the elastic reset member to the locking member 213, the locking member 213 always has a tendency to unlock from the installation body, so as to achieve quick unlocking.
[0109] Please refer to Figures 15-18 In an optional embodiment, the locking member 213 is rotatably mounted on the movable bracket 210. The movable bracket 210 has a first slot 217, and the locking member 213 has a second slot 2133. The second elastic reset member 216 is a spring sheet, one end of which is engaged in the first slot 217, and the other end of which is engaged in the second slot 2133. The spring sheet causes the locking member 213 to always have a tendency to rotate away from the locking mating part 120.
[0110] When a second elastic reset member 216 is provided on the movable bracket 210 and a locking member 213 is rotatably provided on the movable bracket 210, a driving surface 2233 and a mating surface 2234 connected to each other can be provided in the first guide groove 223, and the extension direction of the driving surface 2233 and the extension direction of the mating surface 2234 are set at an angle.
[0111] During the rotation of the locking member 213, the guide portion 2131 of the locking member 213 moves along the driving surface 2233. When the locking member 213 engages with the locking mating portion 120, the guide portion 2131 is located away from the mating surface 2234. When the locking member 213 is reset, the guide portion 2131 is located at the connection between the driving surface 2233 and the mating surface 2234. The area formed between the driving surface 2233 and the mating surface 2234 provides a larger space for the guide portion 2131 to move, making the rotation process of the locking member 213 smoother.
[0112] In some embodiments, the mounting body is provided with a first stop 140 and a second stop 150 opposite to each other along the moving direction of the movable bracket 210. The movable bracket 210 is in a first extreme position when it abuts against the first stop 140, at which time the closing member 400 closes the storage opening. As the movable bracket 210 moves toward the second stop 150, the closing member 400 opens the storage opening until the movable bracket 210 abuts against the second stop 150 and is in a second extreme position.
[0113] The first stop 140 and the second stop 150 are disposed opposite to each other on the guide rail 100 along the moving direction of the movable bracket 210. The two opposing surfaces of the first protrusion 218 and the second protrusion 219 are the first stop surface 2183 and the second stop surface 2192, respectively. The first stop surface 2183 faces the first stop 140, and the second stop surface 2192 faces the second stop 150.
[0114] The pull cable 322 can drive the slider 220 and the movable bracket 210 to move synchronously toward the first stop 140 until the first stop surface 2183 of the first protrusion 218 abuts against the first stop 140. At this time, the sliding door or drawer closes the storage opening. The slider 220 can move relative to the movable bracket 210 toward the first abutment surface 2181 under the drive of the pull cable 322. The pull cable 322 can also drive the slider 220 and the movable bracket 210 to move synchronously toward the second stop 150 until the second stop surface 2192 of the second protrusion 219 abuts against the second stop 150. At this time, the storage opening is fully opened.
[0115] Figures 19-21The three working states of the storage device 10 are shown. The working principle of the storage device 10 provided in this embodiment is as follows: When the storage device 10 needs to be closed, the motor 310 drives the sliding member 220 and the movable bracket 210 to move synchronously toward the first stop member 140 through the cable mechanism 320 until the movable bracket 210 abuts against the first stop member 140. At this time, the movable bracket 210 is at the first extreme position, and the closing member 400 closes the storage opening. At this time, the motor 310 continues to drive the sliding member 220 to move relative to the movable bracket 210 toward the first abutment surface 2181 through the cable mechanism 320. During the movement, the sliding member 220 drives the locking member 213 to cooperate with the locking engagement part 120 through the cooperation of the first guide structure and the guide part 2131. At this time, the movable bracket 210 and the closing member 400 are locked with the mounting body. If the closing member 400 is subjected to an accelerating impact or a large external force that causes it to open, it is not easy to move relative to the mounting body, thereby enabling the storage device 10 to be stably kept in the closed state.
[0116] When it is necessary to change the storage device 10 from the closed state to the open state, the motor 310 drives the sliding member 220 to move relative to the movable bracket 210 toward the second abutment surface 2191 through the cable mechanism 320. During the movement, the sliding member 220 drives the locking member 213 to disengage from the locking engagement part 120 through the cooperation of the first guide structure and the guide part 2131 until the sliding member 220 abuts against the second abutment surface 2191. At this time, the motor 310 continues to drive the sliding member 220 and the movable bracket 210 to move synchronously toward the second stop member 150 through the cable mechanism 320 until the movable bracket 210 abuts against the second stop member 150 and is in the second limit position.
[0117] Please see Figure 22 , Figure 23 In some embodiments, the mounting body is provided with a first limit switch 160 electrically connected to the drive mechanism 300. The closure 400 abuts against the first limit switch 160 when the movable bracket 210 is in the first extreme position, and the closure 400 can disengage from the first limit switch 160 under external force. The mounting body is provided with a second limit switch 170 electrically connected to the drive mechanism 300. The closure 400 abuts against the second limit switch 170 when the movable bracket 210 is in the second extreme position, and the closure 400 can disengage from the second limit switch 170 under external force. A handle for easy pushing by the user can be provided on the closure 400.
[0118] The first limit switch 160 and the second limit switch 170 are located at both ends of the guide rail 100 along its length. The first limit switch 160 and the second limit switch 170 can be electrically connected to the controller inside the motor 310.
[0119] When the movable support 210 is in the first extreme position and the locking member 213 is disengaged from the locking engagement part 120, the closing member 400 is pushed in the direction of opening the storage opening until the closing member 400 disengages from the first limit switch 160. At this time, the motor 310 resumes operation to drive the closing member 400 to open the storage opening. When the movable support 210 is in the second extreme position, the closing member 400 is pushed in the direction of closing the storage opening until the closing member 400 disengages from the second limit switch 170. At this time, the motor 310 resumes operation to drive the closing member 400 to close the storage opening.
[0120] It should be understood that the first limit switch 160 and the second limit switch 170 can also be replaced by non-contact triggering devices. When the movable bracket 210 is in the first or second limit position, the closing member 400 does not need to abut against the non-contact triggering device. When the movable bracket 210 is in the first or second limit position, if the non-contact triggering device detects a change in the distance between the closing member 400 and the non-contact triggering device, the motor 310 resumes operation to drive the closing member 400 to open or close the storage opening.
[0121] Please see Figures 24-26 The movable bracket 210 is provided with a sliding guide rail 2101, and the sliding member 220 is provided with a second sliding part 221 that slides in cooperation with the sliding guide rail 2101.
[0122] The movable bracket 210 is provided with two second mounting slots 2102. The two second mounting slots 2102 are respectively provided with a third elastic reset member 202 and a fourth elastic reset member 203. The two ends of the sliding member 220 extend into the two second mounting slots 2102 and abut against the third elastic reset member 202 and the fourth elastic reset member 203. Under the combined action of the third elastic reset member 202 and the fourth elastic reset member 203, the sliding member 220 remains relatively stationary with the movable bracket 210.
[0123] Both the third elastic reset element 202 and the fourth elastic reset element 203 can be selected as elastic reset elements such as springs or sheet springs, and there is no limitation on this.
[0124] By setting a first limit switch 160 and a second limit switch 170 at both ends of the guide rail 100, when the closure member 400 closes the storage opening, the user pushes the closure member 400 a certain distance in the opening direction, and the third elastic reset member 202 is compressed, causing the closure member 400 to disengage from the first limit switch 160. The motor 310 can then automatically drive the closure member 400 to open the storage opening. When the storage opening is fully open, the user pushes the closure member 400 a certain distance in the closing direction, and the fourth elastic reset member 203 is compressed, causing the closure member 400 to disengage from the second limit switch 170. The motor 310 can then automatically drive the closure member 400 to close the storage opening.
[0125] In an optional embodiment, the first guide groove 223 includes a first horizontal segment 2232, an inclined segment 2231, and a second horizontal segment 2235 connected in sequence, such as Figure 27 As shown, when both the third elastic reset member 202 and the fourth elastic reset member 203 are in their initial state, the sliding member 220 is basically in the centered position, and the guide portion 2131 is located in the middle of the second horizontal segment 2235; as Figure 28 As shown, when the sliding member 220 compresses the third elastic reset member 202, the guide portion 2131 moves from the second horizontal section 2235 through the inclined section 2231 to the first horizontal section 2232, and the locking member 213 cooperates with the locking engagement portion 120.
[0126] like Figure 29 As shown, when the movable support 210 is in the first extreme position and the locking member 213 is disengaged from the locking engagement part 120, the closing member 400 is pushed in the direction of opening the storage opening. The movable support 210 moves relative to the sliding member 220, and the guide part 2131 moves within the second horizontal section 2235 to a position close to the inclined section 2231. However, at this time, the guide part 2131 is still within the second horizontal section 2235, so the locking member 213 does not move relative to the movable support 210, that is, the locking member 213 is not in the locked state. At this time, the closing member 400 disengages from the first limit switch 160, and the motor 310 resumes operation to drive the closing member 400 to open the storage opening.
[0127] like Figure 30 As shown, when the movable support 210 is in the second extreme position, the closing member 400 is pushed in the direction of closing the storage opening. The movable support 210 moves relative to the sliding member 220, and the guide part 2131 moves within the second horizontal section 2235 to a position away from the inclined section 2231. At this time, the closing member 400 disengages from the second limit switch 170, and the motor 310 resumes operation to drive the closing member 400 to close the storage opening.
[0128] Figure 31The illustration shows the storage device 10 being used in a car, for example, the storage device 10 could be a glove box, storage box or refrigerator.
[0129] In summary, this application provides a locking mechanism and a storage device 10. It employs a motor 310 without a self-locking function, combined with a cable mechanism 320, to drive the movable component 200. When the movable component 200 closes the storage opening, it achieves a locking function with the mounting body, effectively solving the problem of insufficient stability caused by the lack of a locking mechanism in traditional storage devices 10. Specifically, when the sliding door or drawer is impacted by external force, the locking design of the locking member 213 prevents the sliding door or drawer from moving in the opposite direction, avoiding accidental opening of the storage device 10, thereby significantly improving the stability of the storage device 10 in the closed state. Furthermore, through the synergistic effect between the sliding member 220 and the movable bracket 210, combined with the design of the guide groove, locking member 213, and reset member, the storage device 10 achieves precise opening and closing control and reliable locking function. The application of the first elastic reset member 201 and the second elastic reset member 216 not only ensures reliable locking and unlocking of the locking member 213 and the mounting body, but also automatically adjusts its position during the movement of the sliding member 220, ensuring smooth system operation. Simultaneously, the arrangement of the first stop member 140 and the second stop member 150, as well as the first abutment surface 2181 and the second abutment surface 2191, further optimizes the movement range of the movable bracket 210 and the stability of the opening and closing process. This storage device 10 has advantages such as compact structure, convenient operation, and high safety, making it particularly suitable for applications requiring frequent opening and closing and high stability.
[0130] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
