Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, and in particular to a locking mechanism and electronic equipment. Background Technology

[0002] With the widespread application and technological innovation of electronic devices, the usage scenarios of these devices are becoming increasingly diversified. In special application scenarios such as logistics transportation and intelligent inspection, a large number of electronic devices need to be mounted on mobile platforms to achieve dynamic operations. These electronic devices need to be frequently deployed, retrieved, and recharged at different locations. During this process, in order to ensure that the electronic devices remain stable and do not fall off during transportation, a mounting and fixing structure is usually used to fix the electronic devices to the mobile platform.

[0003] Currently, the primary mounting structure for electronic devices on mobile platforms is bolt-fixed. This structure uses screws to secure the electronic device to the mounting surface of the mobile platform. After installation, charging is done manually by plugging and unplugging the charging plug. However, in practice, the bolt-fixing method is cumbersome. Each time the device is installed or removed, screws need to be tightened multiple times using screwdrivers or other tools, which is time-consuming and inefficient. Furthermore, repeated tightening can strip screw holes or damage threads, severely affecting the reliability and lifespan of the mounting structure. In addition, manually plugging and unplugging the charging plug requires handling each device individually, which is not only labor-intensive but also prone to errors such as missing or incorrect plugging when there are many devices, leading to power outages, shutdowns, or circuit damage. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a locking mechanism and electronic device, which aims to solve the technical problems of the existing technology where the installation and fixing structure of electronic devices on mobile platforms is mainly bolt-fixed, which is cumbersome to operate and has low equipment loading and unloading efficiency. At the same time, the manual plugging and unplugging of charging plugs requires operation on each device, which is not only labor-intensive, but also prone to problems such as missing plugging or incorrect plugging when there are many devices, leading to equipment power failure or circuit damage.

[0005] One aspect of this utility model is to provide a locking mechanism, including a base plate, a charging component disposed at one end of the base plate, and locking components symmetrically disposed on both sides of the charging component. The charging component includes a first mounting plate and a charging plug disposed at the top of the first mounting plate. The bottom end of the first mounting plate is fixedly connected to the base plate by a plurality of first bolts.

[0006] The locking assembly includes a second mounting plate and a locking hook. The bottom end of the second mounting plate is fixedly connected to the base plate by a plurality of second bolts. The locking hook includes a hook head and a connecting part connected to the hook head. The connecting part is hinged to the top end of the second mounting plate by a torsion spring.

[0007] Furthermore, the top of the second mounting plate is provided with a positioning post and a first placement groove. The positioning post is arranged along the thickness direction of the second mounting plate, and the torsion spring is sleeved on the outer peripheral surface of the positioning post. One end of the torsion spring is located in the first placement groove.

[0008] The connecting part is provided with a positioning hole and a second placement groove. The positioning hole and the positioning post are in clearance fit. The other end of the torsion spring is located in the second placement groove.

[0009] Furthermore, the locking assembly also includes a limiting plate and a limiting bolt. The limiting plate is located on the side of the connecting part away from the second mounting plate. The end of the positioning post is provided with an internal threaded hole adapted to the limiting bolt. The limiting bolt passes through the limiting plate and connects to the internal threaded hole to limit the connecting part between the limiting plate and the second mounting plate.

[0010] The second mounting plate is provided with a limiting protrusion on one side of the positioning post. The limiting protrusion is located directly below the connecting part. The limiting protrusion has an inclined abutment surface on the side opposite to the connecting part. The abutment surface is used to abut against the connecting part to limit the maximum angle of rotation of the locking hook around the positioning post.

[0011] Furthermore, the top of the second mounting plate is provided with a guide groove, and the guide groove and the positioning post are located on the same side of the second mounting plate.

[0012] Furthermore, the charging assembly also includes at least two guide posts, which are arranged along the thickness direction of the first mounting plate, and the guide posts and the charging plug are located on the same side of the first mounting plate.

[0013] Furthermore, the charging assembly also includes a buffer pad and a fixing plate, wherein the buffer pad and the charging plug are located on the same side of the first mounting plate;

[0014] The buffer pad has a mounting groove on one side, which is adapted to the fixing plate. The fixing plate is fixedly connected to the first mounting plate by a number of fixing bolts to clamp and fix the buffer pad to the first mounting plate.

[0015] Furthermore, the locking mechanism also includes at least two pads. A plurality of pads are spaced apart on the base plate located between the two locking components. The pads are arranged along the length direction of the base plate, and the upper surface of the pads is 2mm-4mm higher than the upper surface of the base plate.

[0016] Another aspect of this utility model is to provide an electronic device, including a device body and the aforementioned locking mechanism. One end of the device body is provided with a charging interface, which is adapted to the charging plug. The device body is connected to the charging plug through the charging interface to achieve charging.

[0017] Furthermore, the device body is also provided with at least two guide sleeves, the guide sleeves and the charging interface are located on the same side of the device body, and the inner diameter of the guide sleeve and the outer diameter of the guide post are in clearance fit.

[0018] Furthermore, the other end of the device body is provided with locking plates on both sides. The locking plate includes a guide portion and a handle portion integrally connected to the guide portion. The handle portion is provided with a gripping hole, and the end of the guide portion is used to insert into the guide groove.

[0019] The guide portion is also provided with a buckle protrusion, and a buckle groove is formed between the buckle protrusion and the handle portion. The buckle groove is used to engage with the hook head, and the device body is fixed by the cooperation of the locking plate and the locking component.

[0020] Compared to existing technologies, the advantages of this invention's locking mechanism and electronic device are as follows: Through the snap-fit ​​connection between the locking hook in the locking assembly and the locking plate on the device body, and the precise docking between the charging plug in the charging assembly and the charging plug on the device body, the device body achieves self-locking and charging upon positioning. Specifically, in practical applications, operators only need to perform simple push-pull movements to quickly complete the installation and disassembly of the device body, significantly saving time compared to bolt fixing and significantly improving the efficiency of device deployment and retrieval. Furthermore, when needed, a simple press operation allows for convenient unlocking, further enhancing operational convenience. Simultaneously, during device installation, the precise alignment of the guide post and guide sleeve automatically and accurately inserts the charging plug into the charging interface, enabling simultaneous installation and charging of the device body. This eliminates the need for manual insertion and removal of each device individually, saving manpower and ensuring the accuracy and completeness of charging, effectively preventing issues such as missed or incorrect insertions.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Please see Figures 1 to 2 The image shows the locking mechanism of this utility model, which includes a base plate 10, a charging component disposed at one end of the base plate 10, and locking components symmetrically disposed on both sides of the charging component. Specifically, the charging component includes a first mounting plate 21 and a charging plug 22 disposed at the top of the first mounting plate 21. The bottom end of the first mounting plate 21 is fixedly connected to the base plate 10 by a number of first bolts.

[0035] Furthermore, the charging assembly also includes at least two guide posts 23. In this embodiment, the first mounting plate 21 is provided with two guide posts 23, which are symmetrically arranged on both sides of the charging plug 22, and the ends of the guide posts 23 are tapered. The guide posts 23 are arranged along the thickness direction of the first mounting plate 21 and are located on the same side of the first mounting plate 21 as the charging plug 22. Their function is to cooperate with the guide sleeve 53 on the device body 51 to assist the charging plug 22 in being accurately inserted into the charging interface 52 of the device body 51. The tapered end of the guide post 23 can more easily guide the guide post 23 into the guide sleeve 53, improving the alignment efficiency during the installation of the device body 51.

[0036] Furthermore, the charging assembly also includes a buffer pad 24 and a fixing plate 25. The buffer pad 24 is made of a highly elastic material and is located on the same side of the first mounting plate 21 as the charging plug 22. In this embodiment, a mounting groove is provided on one side of the buffer pad 24, which is adapted to the fixing plate 25. The fixing plate 25 is fixedly connected to the first mounting plate 21 by a number of fixing bolts 26 to clamp and fix the buffer pad 24 to the first mounting plate 21. In practical applications, the buffer pad 24 can provide sufficient elasticity when the device body 51 is fixed to eliminate the fitting gap that exists during the process of the locking hook 32 hooking the locking plate 54, so that the device body 51 is firmly locked on the locking mechanism and will not cause noise or loosening failure due to vibration.

[0037] As an example, the locking assembly is used to lock the device body 51. The locking assembly includes a second mounting plate 31 and a locking hook 32. The bottom end of the second mounting plate 31 is fixedly connected to the base plate 10 by a number of second bolts. The locking hook 32 includes a hook head 322 and a connecting part 321 connected to the hook head 322. The connecting part 321 is hinged to the top end of the second mounting plate 31 by a torsion spring 33. The side of the hook head 322 facing away from the connecting part 321 has an arc-shaped structure, and an L-shaped groove is formed between the hook head 322 and the connecting part 321.

[0038] Furthermore, the top of the second mounting plate 31 is provided with a positioning post 311 and a first placement groove 312. The positioning post 311 is arranged along the thickness direction of the second mounting plate 31. A torsion spring 33 is sleeved on the outer peripheral surface of the positioning post 311. One end of the torsion spring 33 is located in the first placement groove 312. The connecting part 321 is provided with a positioning hole and a second placement groove 323. The positioning hole and the positioning post 311 are in clearance fit. The other end of the torsion spring 33 is located in the second placement groove 323.

[0039] Furthermore, the locking assembly also includes a limiting plate 34 and a limiting bolt 35. The limiting plate 34 is located on the side of the connecting part 321 away from the second mounting plate 31. The end of the positioning post 311 is provided with an internal threaded hole adapted to the limiting bolt 35. The limiting bolt 35 passes through the limiting plate 34 and connects to the internal threaded hole to limit the connecting part 321 between the limiting plate 34 and the second mounting plate 31. The second mounting plate 31 is also provided with a limiting protrusion 314 on the side where the positioning post 311 is located. The limiting protrusion 314 is located directly below the connecting part 321. The side of the limiting protrusion 314 opposite to the connecting part 321 is provided with an inclined abutment surface. The abutment surface is used to abut against the connecting part 321 to limit the maximum angle of rotation of the locking hook 32 around the positioning post 311. When the torsion spring 33 is in its natural state, there is a gap between the connecting part 321 and the limiting protrusion 314. The combination of the limiting plate 34, the limiting bolt 35 and the limiting protrusion 314 effectively prevents the locking hook 32 from rotating excessively, ensuring the reliability of the locking assembly.

[0040] Furthermore, the top of the second mounting plate 31 is also provided with a guide groove 313. The guide groove 313 and the positioning post 311 are located on the same side of the second mounting plate 31. The guide groove 313 is used to engage with the guide part 542 on the equipment body 51 to further assist the locking hook 32 in positioning and locking the equipment body 51.

[0041] Furthermore, the locking mechanism also includes at least two pads 41. In this embodiment, two pads 41 are spaced apart on the base plate 10 located between the two locking components. The pads 41 are arranged along the length of the base plate 10 and are fixedly connected to the base plate 10 by a plurality of third bolts 42. The upper surface of the pads 41 is 2mm-4mm higher than the upper surface of the base plate 10. As a specific example, in this embodiment, the upper surface of the pads 41 is 3mm higher than the upper surface of the base plate 10. It should be understood that the pads 41 can be made of nylon material. The upper surface of the pads 41 is smooth. In actual use, the resistance is small when the device body 51 slides on it, which improves the ease of picking up and putting down the device body 51 on the locking mechanism, and also avoids wear on the bottom paint surface of the device body 51.

[0042] Please see Figures 3 to 8 The diagram shows the electronic device of this utility model, which includes a device body 51 and a locking mechanism as described in the above embodiment. One end of the device body 51 is provided with a charging interface 52, which is adapted to a charging plug 22. The device body 51 is connected to the charging plug 22 through the charging interface 52 to achieve charging.

[0043] Furthermore, the device body 51 is also provided with at least two guide sleeves 53. In this embodiment, the device body 51 is provided with two guide sleeves 53. The guide sleeves 53 and the charging interface 52 are located on the same side of the device body 51. The inner diameter of the guide sleeve 53 and the outer diameter of the guide post 23 are in clearance fit. The two fit together to help the charging plug 22 to be accurately inserted into the charging interface 52.

[0044] Furthermore, locking plates 54 are respectively provided on both sides of the other end of the device body 51. The locking plate 54 includes a guide portion 542 and a handle portion 541 integrally connected to the guide portion 542. The handle portion 541 is provided with a gripping hole, and the end of the guide portion 542 is used to insert into the guide groove 313. The guide portion 542 is also provided with a snap-fit ​​protrusion 543, and a snap-fit ​​groove is formed between the snap-fit ​​protrusion 543 and the handle portion 541. The snap-fit ​​groove is used to engage with the hook head 322. The side of the snap-fit ​​protrusion 543 facing away from the handle portion 541 has an arc-shaped structure so as to abut against the arc-shaped structure of the hook head 322. In this embodiment, the snap-fit ​​groove has an inverted U-shaped structure, and the device body 51 is fixed by the cooperation of the locking plate 54 and the locking component. It should be noted that the handle 541 in this embodiment is designed to protrude outward, that is, the handle 541 extends beyond the end face of the device body 51. This design makes it convenient to pick up the device body 51, and at the same time, it can protect the buttons and connectors installed on the surface of the device body 51 from being deformed and damaged by bumps.

[0045] Furthermore, a handle 55 is provided on the top surface of the equipment body 51 for carrying the equipment body 51.

[0046] In practical applications, the electronic device of this utility model can be used as follows:

[0047] When it is necessary to fix and charge the device body 51, the operator can first use the handle 55 on the top surface of the device body 51 to lift the entire device body 51 above the base plate 10 and place it on the pad 41 located between the two second mounting plates 31. Then, the operator can firmly grasp the handles 541 in the locking plates 54 on both sides of the device body 51 and apply inward pushing force, so that the device body 51 slides above the pad 41 in the direction of the charging plug 22. During this process, the guide post 23 on the first mounting plate 21, with its conical end, smoothly enters the guide sleeve 53 on the device body 51, correcting the movement direction of the device body 51, thereby ensuring that the charging plug 22 can be accurately inserted into the charging interface 52. As the device body 51 continues to move inward, the arc surface of the latching protrusion 543 on the latching plate 54 abuts against the arc surface of the hook head 322, causing the hook head 322 to move downward under force. The entire latching hook 32 rotates around the positioning pin 311 as the rotation axis in the direction of the limiting protrusion 314. At the same time, the guide part 542 on the latching plate 54 gradually inserts into the guide groove 313 on the second mounting plate 31. Until the latching protrusion 543 enters the space above the L-shaped slot between the hook head 322 and the connecting part 321, under the combined action of the rebound force of the torsion spring 33 and the buffer pad 24, the hook head 322 will enter the latching groove on the latching plate 54 and be tightly fastened with the latching protrusion 543. At this time, the operator can release their hands. The device body 51 has been firmly locked on the base plate 10, and the charging plug 22 has been inserted into the charging interface 52, realizing the stable fixation and charging of the device body 51.

[0048] When it is necessary to remove the equipment body 51, the operator holds the handles 541 of the locking plates 54 on both sides of the equipment body 51 with both hands, applies a slight pushing force inward and presses down on the hook head 322 of the locking hook 32, so that the locking hook 32 rotates around the positioning post 311 in the direction of the limiting protrusion 314 until the connecting part 321 of the locking hook 32 abuts against the contact surface of the limiting protrusion 314. At this time, the top height of the hook head 322 of the locking hook 32 will be lower than the bottom height of the buckling protrusion 543 on the locking plate 54. Keeping the pressing action unchanged, the operator can easily remove the equipment body 51 by gently pulling outward while holding the handles 541.

[0049] In summary, the beneficial effects of the locking mechanism and electronic device of this utility model are as follows: Through the snap-fit ​​connection between the locking hook in the locking assembly and the locking plate on the device body, and the precise docking between the charging plug in the charging assembly and the charging plug on the device body, the device body achieves self-locking and charging upon positioning. Specifically, in practical applications, operators only need simple pushing and pulling actions to quickly complete the installation and disassembly of the device body, significantly saving time compared to bolt fixing and significantly improving the efficiency of device deployment and retrieval. Furthermore, when needed, a simple pressing operation allows for convenient unlocking, further enhancing operational convenience. Simultaneously, during device installation, the precise alignment of the guide post and guide sleeve automatically and accurately inserts the charging plug into the charging interface, achieving simultaneous installation and charging of the device body. This eliminates the need for manual insertion and removal of each device individually, saving manpower and ensuring the accuracy and integrity of charging, effectively preventing issues such as missed or incorrect insertions.
