[0036] See Figure 1 , Figure 2 , Figure 1 An explosion schematic diagram of a protective device for an electronic device according to an embodiment of this application is shown. Figure 2 A schematic diagram of the structure of a protection device for an electronic device according to an embodiment of this application is shown.

[0037] An embodiment of this application provides a protective device for electronic devices, including a housing 10, a locking component 21, a first locking claw 22, and a driving assembly 30, which enables the locking and fixing of electronic devices such as tablet computers and mobile phones, thereby improving stability and convenience.

[0038] In this embodiment, a locking member 21 and a first switch 41 are provided on one side of the housing 10. At least one claw is disposed on one side of the housing 10, and the claw is adjacent to and / or opposite to the locking member 21; the locking member 21 and the claw are configured to fix at least two sides of the electronic device. A drive assembly 30 is disposed within the housing 10 and connected to the claw. The first switch 41 is configured such that when the side of the electronic device abuts against the first switch 41, the drive assembly 30 is controlled to drive the claw to move inward to fix the electronic device.

[0039] The housing 10 may be made of engineering plastic material, which can effectively protect the internal components and provide external protection for the electronic device. The housing 10 has a rectangular parallelepiped structure and includes a front shell 11 and a base 12. The front shell 11 and the base 12 enclose a cavity, in which the drive assembly 30 is installed.

[0040] A latching member 21 is provided on one side of the housing 10. The latching member 21 is used to abut against one side of the electronic device and serves to support the electronic device.

[0041] The protective device includes at least one claw, which is disposed on one side of the housing 10 and adjacent to the engaging member 21. Alternatively, the claw and engaging member 21 are disposed opposite each other. Or, one claw is adjacent to one engaging member 21, and the other claw is disposed opposite to the engaging member 21. The engaging member 21 and the claw are respectively configured to secure at least two sides of the electronic device, thereby clamping the electronic device.

[0042] A drive assembly 30 is disposed inside the housing 10 and is connected to the gripper claw to drive the gripper claw to move. A first switch 41 is also provided on one side of the housing 10. The first switch 41 is electrically connected to the drive assembly 30. The first switch 41 is configured such that when the side of the electronic device abuts against the engaging member 21, the first switch 41 is triggered. The first switch 41 controls the drive assembly 30 to drive the gripper claw to move inward, thereby fixing it to the side of the electronic device and achieving clamping and fixing of the electronic device.

[0043] In one embodiment, the latching member 21 is integrally formed with the front shell 11, the latching member 21 is disposed at one end of the front shell 11, and the first switch 41 is installed on the inner side of the latching member 21 so as to contact the lower side of the electronic device.

[0044] At least one chuck includes a first chuck 22, which is movably disposed on the upper side of the housing 10 and can move inward or outward along the length direction perpendicular to the housing 10.

[0045] The first claw 22 has a plate-like structure and is connected to the drive assembly 30. The first claw 22 is used to clamp and fix the upper side of the electronic device. Furthermore, a silicone pad is attached to the part of the first claw 22 that contacts the electronic device to prevent scratching the side of the electronic device, while also increasing friction and improving the clamping stability of the first claw 22.

[0046] The latching component 21 has a plate-like structure and is used to latch and fix the lower side of the electronic device. A silicone pad is also attached to the part of the latching component 21 that contacts the electronic device. Furthermore, the latching component 21 is equipped with a first switch 41, which is a tactile microswitch. The first switch 41 is mounted on the contact surface between the latching component 21 and the electronic device. When the electronic device is placed on the latching component 21 and a certain pressure is applied, the first switch 41 can be triggered.

[0047] The drive assembly 30 is installed in the cavity inside the housing 10. The output end of the drive assembly 30 is connected to the first claw 22, driving the first claw 22 to move outward or inward to adjust the distance between the first claw 22 and the engaging member 21 to accommodate electronic devices of different sizes, and driving the first claw 22 or the engaging member 21 to move inward to fix the electronic device.

[0048] In the specific implementation process, when no electronic device is placed, the first claw 22 and the engaging member 21 are at their maximum distance from each other, the drive assembly 30 is stationary, and the first switch 41 is in the off state. The lower side of the electronic device to be protected is placed on the engaging member 21, and pressure is applied to the first switch 41 on the engaging member 21 to turn it on.

[0049] After the first switch 41 is turned on, it sends an electrical signal to the control circuit in the drive assembly 30. After receiving the signal, the control circuit drives the first claw 22 to move inward, so that the inner surface of the first claw 22 engages with the upper side of the electronic device, fixing the electronic device between the two.

[0050] When it is necessary to remove the electronic device, the drive component 30 reverses the drive to move the first claw 22 outward, so that the first claw 22 separates from the electronic device. At this time, the distance between the first claw 22 and the locking member 21 increases, the electronic device loses the fixing force, and can be easily removed from the locking member 21.

[0051] In summary, the aforementioned protective device for electronic devices enables convenient and quick locking and fixing of the electronic devices, thereby improving the user experience. Simultaneously, the first claw 22 cooperates with the locking component 21 to enhance the stability of the fixation, effectively protecting the electronic devices from impacts and scratches, providing reliable protection. Furthermore, the device has a compact structure and small size, improving space utilization.

[0052] In one embodiment, the chuck further includes a second chuck 23 and a third chuck 24, which are disposed opposite to each other on both sides of the housing 10 in the width direction; the output end of the drive assembly 30 is connected to the second chuck 23 and the third chuck 24 respectively.

[0053] Specifically, the second claw 23 has a plate-like structure. One end of the second claw 23 is connected to the drive assembly 30, and the other end is used to fix the left side of the electronic device. A silicone pad is attached to the part of the second claw 23 that contacts the electronic device to prevent scratching the side of the electronic device and to increase friction and improve the stability of the fixation.

[0054] The third claw 24 is a plate-shaped structure, and it is movably disposed on both sides of the housing 10 in the width direction relative to the second claw 23. One end of the third claw 24 is connected to the drive assembly 30, and the other end of the third claw 24 is used to fix the right side of the electronic device. A silicone pad is attached to the part of the third claw 24 that contacts the electronic device.

[0055] The drive assembly 30 drives the second jaw 23 and the third jaw 24 to move outward, increasing the distance between them to accommodate electronic devices of different sizes. The drive assembly 30 also drives the second jaw 23 and the third jaw 24 inward, causing them to engage and secure the left and right sides of the electronic device.

[0056] In one embodiment, a second switch 42 is provided on the second claw 23 or the third claw 24. The second switch 42 is electrically connected to the drive assembly 30. The second switch 42 is configured to trigger the drive assembly 30 to drive the first claw 22, the second claw 23 and the third claw 24 to move outward and separate from the electronic device, respectively.

[0057] Specifically, a second switch 42 is provided on the second claw 23 or the third claw 24. In this embodiment, taking the third claw 24 as an example, the second switch 42 is a push-button switch, which is installed on the outer surface of the third claw 24 for easy user operation.

[0058] When the user needs to disassemble the electronic device, pressing the second switch 42 controls the drive assembly 30 to reverse drive the second claw 23, the third claw 24 and the first claw 22 to move outward, so that the three claws separate from the three sides of the electronic device, thereby making it easier for the user to remove the electronic device and achieving automatic separation.

[0059] Combination Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of the drive assembly 30 provided in one embodiment of this application. In some embodiments, the drive assembly 30 includes a worm motor 31, a large gear 32, a small gear 33, and a connecting rod 34. The small gear 33 meshes with the large gear 32 for transmission, and the output end of the worm motor 31 meshes with the small gear 33 for transmission. The first pawl 22, the second pawl 23, and the third pawl 24 are respectively connected to the large gear 32 through the connecting rod 34.

[0060] Specifically, the worm motor 31 serves as the power source for the drive assembly 30, and is installed within the cavity of the housing 10. The output end of the worm motor 31 is a worm structure, with the helical teeth of the worm meshing with the pinion 33 for transmission.

[0061] The pinion 33 is made of alloy steel and meshes with the worm of the worm motor 31 to transmit the rotational motion of the worm to the large gear 32.

[0062] The large gear 32 is made of alloy steel and is movably mounted in the housing 10 via bearings, allowing it to rotate freely around its own axis. The large gear 32 meshes with the small gear 33 for transmission, and the rotation of the small gear 33 drives the large gear 32 to rotate at a lower speed and a larger torque.

[0063] Three connecting rods 34 are used to connect the large gear 32 to the first pawl 22, the second pawl 23, and the third pawl 24, respectively. The connecting rods 34 are made of stainless steel. One end of each connecting rod 34 is hinged to the edge of the large gear 32 via a pin, and the other end is hinged to the pawl via a pin. When the large gear 32 rotates, the connecting rods 34 drive the first pawl 22, the second pawl 23, and the third pawl 24 to move linearly. By adjusting the rotation direction of the worm gear motor 31, the movement of each of the first pawl 22, the second pawl 23, and the third pawl 24 can be controlled to move outward or inward.

[0064] Combination Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of the third claw 24 provided in one embodiment of this application. In some embodiments, the third claw 24 includes a first clamping plate 241 and a second clamping plate 242, the first clamping plate 241 covering the second clamping plate 242, and one end of the second clamping plate 242 being connected to the connecting rod 34.

[0065] Specifically, the third latch 24 consists of a first latch plate 241 and a second latch plate 242. The first latch plate 241 covers the second latch plate 242. One end of the second latch plate 242 is connected to the connecting rod 34. When the drive assembly 30 is working, the second latch plate 242 is moved along the width direction of the housing 10 through the transmission action of the connecting rod 34, thereby driving the first latch plate 241 to move synchronously, so as to realize the latching and fixing of the right side of the electronic device.

[0066] In one embodiment, a sliding block 243 and a charging component 51 are also included. The sliding block 243 is slidably disposed within the second card plate 242, and one end of the charging component 51 is disposed on the sliding block 243, while the other end extends out of the first card plate 241.

[0067] Specifically, the sliding block 243 is slidably connected to the second card plate 242, and the sliding block 243 is made of engineering plastic. The two sides of the sliding block 243 are provided with grooves that are adapted to the protruding parts on the inner side of the second card plate 242, so that the sliding block 243 can slide freely on the second card plate 242 along its length.

[0068] The charging component 51 is a retractable charging cable. One end of the charging component 51 is mounted on the sliding block 243, and the other end extends out of the first card plate 241 to charge electronic devices. By cooperating with the sliding block 243, the position adjustment flexibility of the charging component 51 is increased, which can meet the charging needs of electronic devices of different sizes.

[0069] In one embodiment, a T-shaped block 244 is also included. One end of the T-shaped block 244 is fixed inside the sliding block 243, and the other end is equipped with a charging interface 511. One end of the charging component 51 is located at the bottom of the sliding block 243 and passes through the T-shaped block 244 to connect with the charging interface 511. The other end is wrapped around the top of the sliding block 243 and connected with the power supply component 52.

[0070] Specifically, the T-block 244 is made of engineering plastic. One end of the T-block 244 is fixed inside the sliding block 243, and the other end of the T-block 244 is equipped with a charging interface 511. The charging interface 511 is compatible with the charging interface 511 of the electronic device and is used to charge the electronic device.

[0071] One end of the charging component 51 is located at the bottom of the sliding block 243 and passes through the T-shaped block 244, connecting to the charging interface 511 to transmit power to the charging interface 511. The other end of the charging component 51 is wrapped around the top of the sliding block 243 and connected to the power supply component 52. Due to the bending design of the charging cable, it has a certain degree of deformation capability. When the electronic device needs to be charged, the charging interface 511 is pulled to extend it, which simultaneously moves the charging component 51 to meet the charging requirements. After charging is completed, the charging interface 511 and the charging component 51 are retracted into the housing 10 to ensure aesthetics.

[0072] Combination Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of the first card plate 241 provided in one embodiment of this application.

[0073] In some embodiments, the T-shaped block 244 is provided with through grooves 245 on both sides; the bottom of the first card plate 241 is provided with a protrusion 246 embedded downward in the through groove 245; it also includes two springs 247, which are installed in the through groove 245, with one end of the spring 247 abutting against the inner wall of the through groove 245 and the other end abutting against the protrusion 246.

[0074] Specifically, the T-shaped block 244 has through slots 245 on both sides to cooperate with the downward protrusion 246 on the bottom of the first card plate 241. In this embodiment, two springs 247 are provided, and the springs 247 are made of metal.

[0075] Two springs 247 are respectively installed in the through slots 245 on both sides of the T-block 244. One end of the spring 247 abuts against the inner wall of the through slot 245, and the other end abuts against the protrusion 246 embedded in the through slot 245 at the bottom of the first card plate 241.

[0076] When charging is required, the charging interface 511 and the charging component 51 are pulled to move, which in turn moves the T-block 244 and the sliding block 243. At this time, the spring 247 is deformed by compression because the downward protrusion 246 of the first card plate 241 is embedded in the through groove 245.

[0077] When charging is complete, the charging interface 511 and the charging component 51 are released. The spring 247 is used to reset the T-block 244 and the sliding block 243 to their initial positions, causing the charging component 51 to retract into the housing 10 and the charging interface 511 to return to its initial position.

[0078] Combination Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of the front shell 11 provided in one embodiment of this application. In some embodiments, the front shell 11 is provided with a mounting cavity 121; the power supply component 52 is disposed in the mounting cavity 121; and the charging component 51 is a flexible connecting wire.

[0079] Specifically, the front cover 11 has a mounting cavity 121, which is a circular groove for mounting the power supply component 52. The mounting cavity 121 has a through hole for the charging component 51 to pass through. The power supply component 52 includes conductive contacts that are electrically connected to external pins to provide power to the charging component 51.

[0080] The charging component 51 is a flexible connecting cable, made of highly flexible copper core cable, with an outer layer of insulating material. The flexible connecting cable can be bent and folded to adapt to charging needs at different angles and positions, making it convenient for users.

[0081] In one embodiment, a plurality of magnets 13 are also included, which are spaced apart within the large gear 32.

[0082] Specifically, after the front shell 11 and the base 12 are installed, the mounting cavity 121 of the front shell 11 is located inside the large gear 32. Multiple magnets 13 are spaced apart inside the mounting cavity 121, that is, multiple magnets 13 are spaced apart inside the large gear 32.

[0083] Furthermore, the magnet 13 is made of strongly magnetic neodymium iron boron material. The magnet 13 is fixed to the bottom of the mounting cavity 121 by means of glue or slots, and multiple magnets 13 are arranged in a certain pattern to form a uniform magnetic field. When the electronic device approaches the protective device, the magnet 13 can generate an attractive force, causing the electronic device to automatically adhere to a suitable position, facilitating quick placement and removal of the electronic device by the user.

[0084] Combination Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of the first locking plate 241 provided in one embodiment of this application. In some embodiments, the first locking claw 22, the locking member 21, the second locking claw 23 and the third locking claw 24 are all provided with an arc-shaped surface 25 at the end away from the front shell 11, and the top of the arc-shaped surface 25 is located above the front shell 11; the end faces of the first locking claw 22, the second locking claw 23 and the third locking claw 24 connected to the front shell 11 are at the same horizontal plane as the end face of the front shell 11.

[0085] Specifically, the first claw 22, the engaging member 21, the second claw 23, and the third claw 24 all have an arc-shaped surface 25 at the ends away from the front housing 11. The top of the arc-shaped surface 25 is located above the end face of the front housing 11, that is, the arc-shaped surface 25 is higher than the end face of the front housing 11, which allows the arc-shaped surface 25 to better conform to the edge contour of the electronic device, increase the contact area between the claw and the device, thereby improving the stability of the fixation, while avoiding damage to the edge of the device.

[0086] The end faces of the first claw 22, the second claw 23, and the third claw 24 connected to the front housing 11 are at the same level as the end face of the front housing 11, so that the end face of the contact part between the front housing 11 and the electronic device is kept flat, which helps to improve the clamping stability of the electronic device.

[0087] The heights of the arc-shaped surfaces 25 on the first jaw 22, the second jaw 23, the third jaw 24, and the engaging component 21 are all the same. That is, the arc-shaped surfaces 25 of the three jaws and the engaging component 21 are all located on the same horizontal plane, so that the clamping height of each jaw and engaging component on the electronic device is consistent, and the force on each side of the electronic device is uniform, thereby further improving the clamping stability.

[0088] The lengths of the arc-shaped surfaces 25 on the first claw 22, the second claw 23, and the third claw 24 are shorter than the length of the arc-shaped surface 25 on the engaging component 21. The engaging component 21 needs to bear more weight support and fixation; the longer arc-shaped surface 25 provides greater friction and support, ensuring the phone won't easily shake or fall out within the protective device. The first claw 22, the second claw 23, and the third claw 24 primarily serve an auxiliary fixing function; the shorter arc-shaped surface 25, while meeting the fixing requirements, won't excessively interfere with the operation and use of the device.

[0089] The curved surface 25 is covered with a silicone pad to cushion the surface and prevent scratches on the electronic device during the fixing process.

[0090] In one embodiment, the arc-shaped surfaces 25 of the second claw 23 and the third claw 24 are provided with uniformly distributed sound holes 26.

[0091] Specifically, the arc-shaped surfaces 25 of the second claw 23 and the third claw 24 are provided with evenly distributed sound outlet holes 26. When the electronic device is placed horizontally, its speakers are usually located on the two sides. When the electronic device is placed inside the protective device, the sound outlet holes 26 allow sound to propagate smoothly, ensuring that users can have a good listening experience when playing audio and video on the device.

[0092] The sound outlet holes 26 are circular, with a diameter of 0.5-1 mm, and are evenly distributed on the arc-shaped surfaces 25 of the second and third latches 23 and 24. This ensures effective sound transmission while preventing dust and debris from entering. The number and size of the sound outlet holes 26 can be adjusted adaptively according to specific needs.

[0093] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
