Description

Technical Field

[0001] This utility model relates to the field of vehicle electronic technology, and more specifically, to a lifting and clamping device for vehicle electronic equipment. Background Technology

[0002] With the rapid development of the automotive industry, more and more cars are beginning to be equipped with electronic entertainment products such as tablets for in-car users to use.

[0003] Currently, there is no fixed storage location for in-vehicle electronic devices on the market. After long-term use and random placement, users often find it difficult to locate the electronic devices when needed, which is quite inconvenient. In addition, some in-vehicle electronic devices are fixed to the vehicle interior, requiring users to operate them from specific locations inside the vehicle, which is inflexible and causes great inconvenience to users, resulting in a poor user experience. Utility Model Content

[0004] In view of this, the present invention provides a vehicle-mounted electronic device lifting and clamping device that is convenient to use and facilitates the storage of electronic devices, in order to solve the problems existing in the background art.

[0005] The objective of this utility model is achieved through the following technical solution.

[0006] A vehicle-mounted electronic device lifting and clamping device includes: a base on which a bracket for placing electronic devices is mounted; a clamping assembly including at least two jaws connected to elastic connectors; a lead screw assembly installed in the base, including a lead screw and a lead screw nut mounted on the lead screw, the lead screw nut having an outwardly protruding cam portion on its outer periphery; and a drive motor for driving the lead screw nut to rotate so that the cam portion contacts and separates from the jaws.

[0007] In the above scheme, the lead screw assembly is located below the bracket, and the top of the base has an opening through which the bracket can be raised and lowered to extend or retract into the base. The gripper is located on the side of the bracket and is used to hold electronic devices placed on the bracket. One end of the elastic connector is connected to the gripper, and the other end is fixed. Initially, the bracket is located inside the base, and the gripper holds the electronic device on the bracket. When the electronic device needs to be retrieved, the drive motor drives the lead screw nut to rotate. The cam portion on the outside of the lead screw nut contacts and pushes the gripper, moving the gripper away from the electronic device, thus releasing the electronic device. At this time, under the limiting action of the cam portion, the elastic connector is in a stretched state. Simultaneously, as the lead screw nut rotates, the lead screw threaded to the lead screw nut moves linearly in the vertical direction, lifting the bracket so that the user can retrieve the electronic device. This completes the action of releasing and raising the electronic device. Similarly, when the user puts the electronic device back, the drive motor reverses, driving the lead screw to rotate in the opposite direction. The lead screw then moves the bracket downwards, causing the bracket to retract into the base. At the same time, the cam separates from the gripper, and under the action of the elastic connector, the gripper clamps the electronic device again, thus completing the storage of the electronic device.

[0008] In one example of this utility model, the gripper includes a clamping end and a contact end, the clamping end being located on the side of the bracket, and the contact end being located on the side of the cam portion.

[0009] In the above scheme, the clamping end is used to contact the side of the electronic device to clamp the electronic device. The side wall of the base is provided with a hole for the jaws to pass through. The contact end is located inside the base. The cam part drives the entire jaw to move by pushing the contact end of the jaw, so that the jaw clamps or releases the electronic device.

[0010] In one example of this utility model, the end face of the contact end is a curved surface with an arc.

[0011] In the above scheme, the end of the curved surface can reduce the friction between it and the cam, making the relative movement between the two smoother.

[0012] In one example of this utility model, the base is provided with a mounting platform, the mounting platform is provided with a fixing block, the gripper is slidably mounted on the mounting platform, and the two ends of the elastic connector are respectively connected to the gripper and the fixing block.

[0013] In the above scheme, the mounting platform is used to provide mounting positions for the grippers. Each gripper is provided with a mounting platform. The mounting platform is provided with a fixing block for connecting with the elastic connector to fix one end of the elastic connector, so that the elastic connector can be stretched when the gripper moves, thus ensuring the realization of the gripper's clamping function.

[0014] In one example of this utility model, the base is provided with a guide post on its side, and the gripper is provided with a guide hole that cooperates with the guide post.

[0015] In the above scheme, by setting matching guide posts and guide holes, the movement path of the gripper is guided to ensure that the gripper does not deviate during the movement.

[0016] In one example of this utility model, a clutch assembly is also included, which includes an output shaft, an adapter plate, and a spring plate; the output shaft is connected to the output end of the drive motor, the adapter plate is connected to the nut, and the output shaft passes through the adapter plate along the thickness direction; the spring plate is used to apply force to the adapter plate to press the adapter plate onto the output shaft, so that the adapter plate rotates with the output shaft.

[0017] In the above scheme, the drive motor drives the output shaft to rotate, which in turn drives the adapter plate and the nut connected to the adapter plate to rotate. The spring can provide a continuous preload force, making the adapter plate and the output shaft in close contact. Through the friction between the adapter plate and the output shaft, the adapter plate rotates with the output shaft. When subjected to external abusive force, and the external force is greater than the preload force of the spring, the adapter plate and the output shaft will rotate relative to each other (equivalent to slippage), breaking the original transmission relationship, thereby achieving the effect of clutch disengagement. The external force will not continue to be transmitted to subsequent components, thus protecting the internal structure from damage and ensuring high reliability.

[0018] In one example of this utility model, the adapter plate is provided with a first fixing groove and a second fixing groove on opposite sides; the spring is sleeved on the output shaft and located in the first fixing groove, and the spring abuts against the bottom surface of the first fixing groove; the outer periphery of the output shaft is provided with an outwardly protruding annular portion, the annular portion is located in the second fixing groove and abuts against the bottom surface of the second fixing groove.

[0019] In the above scheme, the spring and the annular part on the output shaft are located on both sides of the adapter plate, and are respectively set in the first fixing groove and the second fixing groove on both sides of the adapter plate. The spring is sleeved on the output shaft and abuts against the bottom surface of the first fixing groove. By applying force to the bottom surface of the first fixing groove, the adapter plate and the annular part on the output shaft are tightly fitted to achieve synchronous rotation of the adapter plate and the output shaft. When the external abuse force exceeds the threshold, the adapter plate and the output shaft slide relative to each other, achieving the clutch protection effect.

[0020] In one example of this utility model, a guide assembly is also included. The guide assembly includes a guide rod, an end cap, and a spring. The base has a hollow mounting post inside. The guide rod slides through the mounting post. The two ends of the guide rod are respectively connected to the bracket and the end cap. The two ends of the spring abut against the inner wall of the mounting post and the end cap, respectively.

[0021] In the above scheme, multiple sets of guide components are provided, and multiple mounting columns for installing guide components are correspondingly provided in the base. The guide rod slides through the top end face of the mounting column, so that the lifting and lowering of the bracket can be guided by the guide rod. The spring is sleeved on the guide rod, and its two ends abut against the inner wall of the top of the mounting column and the end cap, respectively. When the bracket rises, the guide rod moves up with the bracket, and the spring is compressed at this time. When the bracket falls, the guide rod falls with the bracket, and the spring gradually returns to its initial state during the downward movement of the end cap.

[0022] In one example of this utility model, the top end of the mounting post is recessed inward to form a guide groove, and the guide rod is slidably inserted into the guide groove.

[0023] In the above scheme, the guide rod and the guide groove form a sliding connection. The guide groove guides the movement of the guide rod to ensure the guiding effect on the bracket.

[0024] In one example of this utility model, the bracket is provided with multiple mounting slots, and magnets are installed in the mounting slots.

[0025] In the above solution, magnets are used to attract electronic devices placed on the bracket to prevent the electronic devices from falling or slipping off during the lifting and lowering of the bracket.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: This application sets up a lead screw assembly and provides a protruding cam portion on the outer periphery of the lead screw nut in the lead screw assembly. During the rotation of the lead screw nut, the cam portion can drive the gripper to move, and at the same time, the lead screw also moves up and down with the rotation of the lead screw nut, so as to raise and lower the bracket. This achieves a dual action of raising and clamping the electronic device, which meets various user needs, improves the convenience and user experience, and also facilitates the storage of vehicle electronic devices.

Detailed Implementation

[0037] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Example

[0038] Please refer to Figures 1 to 9A vehicle-mounted electronic device lifting and clamping device includes a base 1, a clamping assembly 3, a lead screw assembly 4, and a drive motor 7. A bracket 2 for placing an electronic device 9 is mounted on the base 1; the clamping assembly 3 includes two grippers 31, each gripper connected to an elastic connector 32; the lead screw assembly 4 is installed inside the base 1, and includes a lead screw 41 and a nut 42 threaded onto the lead screw 41, the nut 42 having an outwardly protruding cam portion 421 on its outer periphery; the drive motor 7 is mounted on the base 1 and is used to drive the nut 42 to rotate, so that the cam portion 421 contacts and separates from the grippers 31.

[0039] In this embodiment, the electronic device 9 can be a mobile phone, tablet, or other electronic product. The lead screw assembly 4 is located below the bracket 2. The top of the base 1 has an opening through which the bracket 2 can be raised and lowered to extend or retract into the base 1. Two grippers 31 are located on both sides of the bracket 2 to hold the electronic device 9 placed on the bracket 2. One end of the elastic connector 32 is connected to the gripper 31, and the other end is fixed inside the base 1. Two sets of cam portions 421 are provided, located on both sides of the lead screw nut 42, corresponding to the two grippers 31.

[0040] Specifically, in the initial state, when the electronic device 9 is in the storage state, the bracket 2 is located inside the base 1, and the gripper 31 holds the electronic device 9 on the bracket 2. When the electronic device 9 needs to be taken out, the drive motor 7 drives the screw nut 42 to rotate. The cam part 421 on the outside of the screw nut 42 contacts and pushes the end of the gripper 31, so that the gripper 31 moves away from the electronic device 9, thereby releasing the electronic device 9. At this time, under the limiting action of the cam part 421, the elastic connector 32 is in a stretched state to ensure that the gripper 31 will not retract and remains in the released state. At the same time, when the screw nut 42 rotates, the screw rod 41 threadedly connected to the screw nut 42 moves upward in the vertical direction, lifting the bracket 2 so that the user can take out the placed electronic device 9. This completes the action of releasing and lifting the electronic device 9. Similarly, when the user puts the electronic device 9 back, the drive motor 7 reverses, drives the screw nut 42 to rotate in the opposite direction, and the screw 41 drives the bracket 2 to move downward, so that the bracket 2 is retracted into the base 1. At the same time, the cam part 421 separates from the gripper 31, the elastic connector 32 resets, so that the two grippers 31 clamp the electronic device 9 again, thus completing the storage of the electronic device 9.

[0041] It is worth mentioning that, such as Figure 3As shown, a certain clearance 43 is reserved between the lead screw 41 and the lead screw 42, so that when the drive motor 7 drives the lead screw 42 to rotate, the lead screw 42 rotates at a certain angle before engaging with the lead screw 41. This allows the cam part 421 to drive the gripper 31 to release the electronic device 9 first, and then engage with the lead screw 41 to move the lead screw 41 upward and lift the bracket 2. This allows the release action of the gripper 31 and the lifting action of the bracket 2 to be carried out in steps to avoid motion interference. Similarly, when storing the electronic device 9, after the bracket 2 descends to the lowest position, the lead screw 42 and the lead screw 41 no longer engage. At this time, as the lead screw 42 continues to rotate, the cam part 421 separates from the gripper 31, allowing the gripper 31 to hold the electronic device 9.

[0042] Preferably, such as Figure 3 As shown, the top surface of the lead screw 41 is connected to the bottom surface of the bracket 2 by the screw 8, so as to drive the bracket 2 to move up and down.

[0043] In this embodiment, the gripper 31 includes a clamping end 311 and a contact end 312. The clamping end 311 is located on the side of the bracket 2, and the contact end 312 is located on the side of the cam portion 421. The clamping end 311 is used to contact the side of the electronic device 9 to clamp the electronic device 9. The side wall of the base 1 is provided with a hole for the gripper 31 and the clamping end 311 of the gripper 31 to pass through. The clamping end 311 clamps the electronic device 9 on the bracket 2 through the hole on the side wall of the base 1. The contact end 312 is located inside the base 1. The cam portion 421 drives the entire gripper 31 to move by pushing the contact end 312 of the gripper 31, so that the clamping end 311 of the gripper 31 clamps or releases the electronic device 9.

[0044] Preferably, Figure 4 This is a partial perspective view of the nut 42 and the gripper 31 in the engaged state (the right side is the perspective view), as shown. Figure 2 and Figure 4 As shown, in order to optimize the internal space of the base 1, the contact surfaces of the two sets of cams 421 that contact the grippers 31 are at different heights, and correspondingly, the contact ends 312 of the two sets of grippers 31 are at different heights.

[0045] Please refer to Figure 3 and Figure 4 The end face of the contact end 312 is a curved surface. The curved surface structure can reduce the friction between the contact end 312 and the cam part 421, making the relative movement between the contact end 312 and the cam part 421 smoother.

[0046] Please refer to Figure 3 The base 1 has two mounting platforms 11. The mounting platform 11 has a first fixing block 111. The gripper 31 is slidably mounted on the mounting platform 11. The two ends of the elastic connector 32 are connected to the gripper 31 and the fixing block respectively.

[0047] Mounting platform 11 is used to provide mounting positions for grippers 31. Each gripper 31 is provided with a mounting platform 11. Mounting platform 11 is provided with a fixing block for connecting with elastic connector 32 to fix one end of elastic connector 32, so that elastic connector 32 can be stretched when gripper 31 moves, ensuring the gripping function of gripper 31 is realized.

[0048] Preferably, to facilitate the installation of the elastic connector 32, a second fixing block 313 is provided on the gripper 31, and the two ends of the elastic connector 32 are respectively installed by the first fixing block 111 and the second fixing block 313.

[0049] Preferably, the elastic connector 32 in this embodiment is a spring. In addition, other connectors with elasticity and reset function can also be selected.

[0050] Please refer to Figure 1 and Figure 2 The base 1 has a guide post 13 on its side, and the gripper 31 has a guide hole 314 that mates with the guide post 13. By setting the matching guide post 13 and guide hole 314, the movement path of the gripper 31 is guided to ensure that the gripper 31 does not deviate during movement.

[0051] Please refer to Figure 2 , Figure 6 and Figure 7 The base 1 is also provided with a clutch assembly 5, which includes an output shaft 51, an adapter plate 52 and a spring piece 53. The output shaft 51 is connected to the output end of the drive motor 7, the adapter plate 52 is connected to the nut 42, and the output shaft 51 passes through the adapter plate 52 along the thickness direction. The spring piece 53 is used to apply force to the adapter plate 52 to press the adapter plate 52 onto the output shaft 51 so that the adapter plate 52 rotates with the output shaft 51.

[0052] Furthermore, the upper and lower surfaces of the adapter plate 52 are respectively provided with a first fixing groove 521 and a second fixing groove 522; the spring piece 53 is sleeved on the output shaft 51 and located in the first fixing groove 521, and the spring piece 53 abuts against the bottom surface of the first fixing groove 521; the outer periphery of the output shaft 51 is provided with an outwardly protruding annular portion 511, the annular portion 511 is located in the second fixing groove 522 and abuts against the bottom surface of the second fixing groove 522.

[0053] Specifically, the drive motor 7 drives the output shaft 51 to rotate, which in turn drives the adapter plate 52 and the nut 42 connected to the adapter plate 52 to rotate. The spring piece 53 and the annular part 511 on the output shaft 51 are located on both sides of the adapter plate 52, and are respectively provided in the first fixing groove 521 and the second fixing groove 522 on both sides of the adapter plate 52. The spring piece 53 is sleeved on the output shaft 51 and abuts against the bottom surface of the first fixing groove 521. During normal operation, the spring plate 53 provides a continuous preload to the bottom surface of the first fixing groove 521, causing the second fixing groove 522 to fit tightly against the top surface of the annular part 511. Through the friction generated, the adapter plate 52 and the output shaft 51 rotate synchronously. When subjected to external abusive force, and the external force is greater than the preload of the spring plate 53, the adapter plate 52 and the output shaft 51 will rotate relative to each other (equivalent to slippage), achieving clutch disengagement and thus achieving overload protection. The external force will not continue to be transmitted to subsequent components, thus protecting the internal structure from damage and ensuring high reliability.

[0054] Preferably, to make the overall structure more compact, the lead screw 41 is hollow inside so that the end of the output shaft 51 can extend into the lead screw 41. The spring piece 53 is installed inside the hollow lead screw 41, which can save installation space and improve space utilization.

[0055] Preferably, the output shaft 51 is a spline shaft with multiple keyways on its outer periphery to facilitate the installation of the spring piece 53.

[0056] Preferably, the adapter plate 52 and the nut 42 are connected by screws 8, and the adapter plate 52 is provided with a plurality of holes for screws 8 to be fastened.

[0057] Please refer to Figure 3 and Figure 8 The base 1 is also provided with a guide assembly 6, which includes a guide rod 61, an end cap 62 and a spring 63. The base 1 is provided with a hollow mounting post 12. The guide rod 61 slides through the mounting post 12. The two ends of the guide rod 61 are connected to the bracket 2 and the end cap 62 respectively. The two ends of the spring 63 abut against the inner wall of the mounting post 12 and the end cap 62 respectively.

[0058] Specifically, the guide assembly 6 is provided in 4 sets, and the base 1 is provided with 4 mounting posts 12 for mounting the guide assembly 6. The guide rod 61 slides through the top end face of the mounting post 12, so that the lifting and lowering of the bracket 2 can be guided by the guide rod 61. The spring 63 is sleeved on the guide rod 61, and its two ends abut against the inner wall of the top of the mounting post 12 and the end cover 62, respectively. When the bracket 2 rises, the guide rod 61 moves up with the bracket 2, and the spring 63 is compressed at this time. When the bracket 2 falls, the guide rod 61 falls down with the bracket 2, and the spring 63 gradually returns to its initial state during the downward movement of the end cover 62.

[0059] Furthermore, the top end of the mounting column 12 is recessed inward to form a guide groove 121, and the guide rod 61 is slidably inserted into the guide groove 121. The guide rod 61 and the guide groove 121 form a sliding connection, and the movement of the guide rod 61 is guided by the guide groove 121 to ensure the guiding effect on the bracket 2.

[0060] Preferably, the two ends of the guide rod 61 are detachably connected to the bracket 2 and the end cap 62 by screws 8, so as to facilitate disassembly and assembly.

[0061] Please refer to Figure 5 The bracket 2 is provided with multiple mounting slots 21, and magnets 22 are installed in the mounting slots 21. The magnets 22 are used to attract electronic devices 9 placed on the bracket 2 to prevent the electronic devices 9 from falling or slipping off during the lifting and lowering of the bracket 2.

[0062] Specifically, the mounting slots 21 are arranged in groups, each group including two mounting slots 21 symmetrically arranged on the upper and lower sides of the bracket 2. Each mounting slot 21 is equipped with a magnet 22. The two magnets 22 in each group of mounting slots 21 are firmly installed in the mounting slot 21 through mutual attraction.

[0063] Please refer to Figure 1 , Figure 2 and Figure 9 The bottom of the base 1 is equipped with a control circuit board 14, which has multiple interfaces for connecting to external power to realize the electric control function of the entire device.
