Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted component technology, specifically to a vehicle-mounted desktop. Background Technology

[0002] A car table is a foldable, multi-functional platform installed on the back of a car seat or in the center console. It primarily provides temporary support for rear passengers and is an important in-vehicle accessory that enhances the comfort and functionality of long-distance travel.

[0003] In related technologies, the design of seat back tray tables suffers from significant space utilization and functional deficiencies. Traditional tray tables are directly installed on the back of the seat using fixed hinges or latches. Because of this fixed installation, disassembly requires removing the hinges, potentially damaging the connection between the tray table and the seat back, hindering disassembly, replacement, and maintenance. Furthermore, even when closed and locked, they continue to encroach on the knee space of rear passengers. Typically employing a single hinge structure, they only support two fixed positions: folded up and horizontally unfolded. This lack of adjustment based on passenger height or usage scenario can lead to screen glare or uncomfortable writing postures. In addition, the rigid connection prevents the tray table from fully embedding into the backrest when folded, affecting aesthetics and potentially causing accidental collisions during sudden braking. Utility Model Content

[0004] In view of this, the present invention provides a vehicle-mounted desktop to solve the problems of existing vehicle-mounted tables being inconvenient to disassemble and unable to be adjusted.

[0005] This utility model provides a vehicle-mounted desktop, including:

[0006] Tabletop;

[0007] The mounting device is suitable for detachable connection to an external connection structure. The mounting device is located on one side of the table and fixedly connected to the table. The mounting device includes at least a mounting housing, a locking block, a connecting block, and an unlocking block. The locking block has a locked state that protrudes from the mounting housing and an unlocked state that retracts into the mounting housing. The unlocking block is suitable for moving the locking block to switch between the locked state and the unlocked state. The connecting block is rotatably connected to the locking block and is suitable for constraining the locking block to rotate about the connecting block.

[0008] Mounting plate, one end of which is rotatably connected to the tabletop, and mounting device is installed through the mounting plate;

[0009] An adjustment device is installed on the side away from the tabletop support surface and is connected to the other end of the tabletop and the mounting plate, respectively. The adjustment device includes an adjustment rod, a first adjustment part, a second adjustment part, and a connecting frame. The connecting frame is fixedly connected to the tabletop. The adjustment rod is adapted to adjust the angle of the tabletop through the first adjustment part and the second adjustment part. The first adjustment part and the second adjustment part are installed on the connecting frame.

[0010] Beneficial Effects: The vehicle-mounted desktop provided by this utility model achieves convenient installation and multi-angle adjustment through innovative installation and adjustment devices, significantly improving its flexibility and stability. The installation device adopts a detachable connection design, achieving quick locking and unlocking through the cooperation of locking and unlocking blocks, facilitating installation and disassembly in different vehicle environments; the rotating connection structure between the connecting block and the locking block effectively constrains the rotation range of the locking block, ensuring the reliability of the locking state. The adjustment device, through the coordinated action of the adjustment rod and the first and second adjustment parts, can precisely control the tilt angle of the tabletop, meeting the needs of users in different usage scenarios. The rotating connection between the installation plate and the tabletop, combined with the through-type design, ensures both overall structural strength and compact storage, significantly improving the user experience in vehicle scenarios.

[0011] In one optional embodiment, the connecting block is fixedly installed on the mounting housing. The connecting block includes a connecting hole, the axial direction of which is not parallel to the installation and travel direction of the mounting device. The locking block includes a rotating part, which is rotatably connected to the connecting hole.

[0012] Beneficial effects: This utility model sets the axial direction of the connecting hole of the connecting block to a non-parallel structure with the installation and travel direction of the mounting device. Combined with the rotating part of the locking block being rotatably connected to the connecting hole, this achieves stable switching between the locking and unlocking states of the locking block. This allows the locking block to reliably rotate in a predetermined direction under force, avoiding jamming or offset and ensuring a tight fit between the mounting device and the external connection structure. Simultaneously, the non-parallel layout optimizes the movement trajectory of the locking mechanism, reduces operating resistance, and the fixed installation method of the connecting block enhances the overall structural rigidity, preventing shaking during locking and improving the vibration resistance of the vehicle desktop during vehicle operation.

[0013] In one alternative embodiment, the locking block further includes a locking latch, the external structure of which includes a locking groove, the locking latch being disposed on the side of the locking block away from the connecting block along the length direction of the locking block, and the locking latch being adapted to engage with the locking groove.

[0014] Beneficial effects: This utility model improves the locking reliability of the installation device by setting a locking buckle at the end of the locking block away from the connecting block, allowing it to precisely match the locking groove of the external structure. The layout of the locking buckle along the length of the locking block utilizes the lever principle. When the locking block is in the locked state, the locking buckle and the locking groove form a stable fastening structure, which can effectively resist vibration and impact during vehicle operation. It is suitable for maintaining the stability of the vehicle desktop in bumpy driving environments, significantly improving safety and ease of operation.

[0015] In one optional embodiment, the connecting block further includes a plug-in portion and a mounting hole, and the unlocking block includes a plug-in groove and a button. The length direction of the plug-in groove is parallel to the length direction of the plug-in portion, and the plug-in groove cooperates with the plug-in portion.

[0016] Beneficial effects: This invention ensures that the unlocking block slides smoothly along a predetermined trajectory by cooperating with the insertion part of the connecting block and the insertion slot of the unlocking block, avoiding deviation or jamming during operation. The parallel alignment design of the insertion slot and the insertion part simplifies the assembly process and enhances structural strength. The cooperation between the insertion part and the insertion slot not only restricts the degree of freedom of movement of the unlocking block but also provides linear guidance for the unlocking process, making the switching of the locking state smoother and more reliable.

[0017] In one optional embodiment, the connecting block further includes a first abutting portion, and the locking block further includes a second abutting portion. When the insertion portion and the insertion groove have a tendency to slide closer to each other, the first abutting portion and the second abutting portion that are in contact with the unlocking block and the locking block generate an abutting force, so that the locking buckle has a tendency to move away from the locking groove with the rotating portion as the axis.

[0018] The mounting device also includes a first elastic element. The connecting block has a mounting hole. The length direction of the first elastic element is parallel to the length direction of the insertion slot. One end of the first elastic element abuts against the unlocking block, and the other end is located in the mounting hole.

[0019] Beneficial effects: This utility model, through the cooperation of the first and second abutting parts, generates an abutting force when the unlocking block slides, causing the locking buckle to disengage from the locking slot around the rotating part, thus achieving the unlocking function. The first elastic element, parallel to the insertion slot, provides a stable reset force and, through the limiting of the mounting hole, ensures that the elastic element does not skew, allowing the unlocking block to automatically return to its locked position and maintain the locked state, improving the ease of operation and safety stability of the vehicle desktop.

[0020] In one alternative embodiment, the mounting device further includes a second elastic member, one end of which abuts against the mounting housing, and the other end of which abuts against the locking block on the side of the locking block close to the connecting block along the length of the locking block.

[0021] Beneficial effects: By adding a second elastic element, this utility model applies a continuous elastic force to the side of the locking block near the connecting block, so that the locking buckle and the locking groove always maintain a tight engagement, thereby improving the stability of the locking state.

[0022] In one optional embodiment, the first adjusting part includes at least a first connecting part and a plurality of adjusting grooves. The first connecting part is rotatably connected to one end of the connecting frame, and the adjusting grooves are adapted to fix the adjusting rod. The second adjusting part includes at least a second connecting part, and the second connecting part is rotatably connected to the other end of the connecting frame.

[0023] Beneficial effects: This utility model achieves precise adjustment of the tabletop angle through the cooperation of multiple adjustment grooves in the first adjustment part and the adjustment rod. Users can flexibly select different gears according to their needs to meet diverse usage scenarios. The first and second connecting parts are rotatably connected to both ends of the connecting frame, forming a stable support structure that maintains balanced force during adjustment. The stepped design of the adjustment grooves allows the adjustment rod to be firmly locked into different positions, ensuring that each angle is securely locked and effectively resisting vibration and impact during vehicle operation.

[0024] In one alternative embodiment, the first adjusting part further includes a slot, and the second adjusting part further includes a locking block and a pressing plate. The slot and the locking block are slidably connected. The pressing plate is adapted to rotate about the second connecting part as an axis in a direction closer to the table. The locking block is adapted to rotate about the second connecting part as an axis in a direction away from the table. The slot is adapted to rotate about the first connecting part as an axis in a direction away from the table.

[0025] Beneficial effects: This utility model achieves quick adjustment of the tabletop angle through a sliding connection design of the slot and the block, combined with the lever operation structure of the pressing plate. When the pressing plate is pressed down around the second connecting part, it drives the block to rotate synchronously and disengage from the slot, allowing the tabletop angle to be freely adjusted. After releasing the pressing plate, the block automatically re-engages and locks with the slot under the elastic reset action, improving the convenience of adjustment. The cooperation design of the slot and the block produces a self-tightening effect when locked, ensuring that the tabletop receives stable support at different angles and effectively resists vehicle bumps.

[0026] In one alternative embodiment, the connecting frame has a groove and a third elastic element, the groove being adapted to receive an adjusting rod, the groove cooperating with the adjusting groove to fix the adjusting rod.

[0027] Beneficial effects: This utility model achieves precise positioning and reliable fixing of the adjusting rod through the cooperation structure of the sliding groove and the adjusting groove of the connecting frame, making the tabletop angle adjustment more stable and easier to operate. The design of the sliding groove provides a clear movement trajectory for the adjusting rod, avoiding deviation or shaking during the adjustment process; the third elastic element continuously applies pressure to ensure that the adjusting rod and the adjusting groove are tightly engaged, preventing accidental loosening caused by vehicle bumps.

[0028] In one optional embodiment, a third elastic element is respectively disposed at the first connecting part and the rotating connection of the connecting frame and the second connecting part and the rotating connection of the connecting frame, which is suitable for resetting the first adjusting part and the second adjusting part.

[0029] Beneficial effects: By setting third elastic elements at the two rotating connections, this utility model enables the first and second adjusting parts to have an automatic reset function, improving the convenience and stability of angle adjustment. The symmetrical arrangement of the third elastic elements provides a balanced reset force for the adjusting mechanism, ensuring that the tabletop can automatically return to its initial position, simplifying the operation process.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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 utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0047] As an important accessory for improving the comfort of rear passengers, the traditional design of the in-vehicle table 1 has obvious defects in terms of space utilization and functionality. Currently, the table 1 is directly installed on the back of the seat back using fixed hinges or latches. This rigid connection method makes disassembly and maintenance extremely inconvenient. If the table 1 needs to be replaced, the entire hinge structure must be removed, which can easily damage the connection parts of the seat back. Even when closed, the table 1 still protrudes outward by 3-5 centimeters, continuously encroaching on the already limited knee space of rear passengers. In terms of functional design, traditional products are usually equipped with only a single hinge structure. The table 1 can only switch between two fixed positions: fully folded and horizontally unfolded. It cannot adjust the tilt angle according to the different heights of children or adults, nor can it meet the needs of various scenarios such as anti-glare for watching movies, writing and drawing, which seriously affects the user experience.

[0048] Existing technology also suffers from shortcomings in both safety and aesthetics. Due to the lack of a retractable design, the closed table 1 cannot be fully embedded inside the seat back, which not only disrupts the overall integrity of the interior but also poses a potential collision risk during sudden braking. When the vehicle brakes suddenly, the protruding edge of the table 1 can easily cause injury to the passenger's knees. In addition, the fixed structure also hinders the integration of extended functions such as seat back storage pockets, further reducing the utilization rate of interior space.

[0049] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.

[0050] According to an embodiment of the present invention, a vehicle-mounted desktop is provided, comprising:

[0051] Tabletop 1; Mounting device 2, adapted for detachable connection to an external connection structure, the mounting device 2 is disposed on one side of the tabletop 1 and fixedly connected to the tabletop 1, the mounting device 2 includes at least a mounting housing 21, a locking block 22, a connecting block 23, and an unlocking block 24, the locking block 22 having a locked state protruding relative to the mounting housing 21 and an unlocked state retracted into the mounting housing 21; the unlocking block 24 is adapted to drive the locking block 22 to move to switch between the locked state and the unlocked state; the connecting block 23 is rotatably connected to the locking block 22, and the connecting block 23 is adapted to constrain the locking block 22 around... The connecting block 23 rotates; the mounting plate 4 is rotatably connected to the tabletop 1 at one end, and the mounting device 2 is installed through the mounting plate 4; the adjusting device 3 is installed on the side away from the supporting surface of the tabletop 1 and is connected to the other end of the tabletop 1 and the mounting plate 4 respectively. The adjusting device 3 includes an adjusting rod 31, a first adjusting part 32, a second adjusting part 33 and a connecting frame 34. The connecting frame 34 is fixedly connected to the tabletop 1. The adjusting rod 31 is adapted to adjust the angle of the tabletop 1 through the first adjusting part 32 and the second adjusting part 33. The first adjusting part 32 and the second adjusting part 33 are installed on the connecting frame 34.

[0052] The vehicle-mounted desktop provided by this utility model achieves convenient installation and multi-angle adjustment through an innovative installation device 2 and adjustment device 3, significantly improving its flexibility and stability. The installation device 2 adopts a detachable connection design, achieving quick locking and releasing through the cooperation of locking block 22 and unlocking block 24, facilitating installation and disassembly in different vehicle environments. The rotating connection structure between connecting block 23 and locking block 22 effectively constrains the rotation range of locking block 22, ensuring the reliability of the locking state. The adjustment device 3, through the coordinated action of adjustment rod 31, first adjustment part 32, and second adjustment part 33, can precisely control the tilt angle of the tabletop 1, meeting the needs of users in different usage scenarios. The rotating connection between the mounting plate 4 and the tabletop 1, combined with a through-type design, ensures overall structural strength while achieving compact storage, significantly improving the user experience in vehicle scenarios.

[0053] In some embodiments, combined with Figure 4 and Figure 5 As shown, the connecting block 23 is fixedly installed on the mounting housing 21. The connecting block 23 includes a connecting hole 233. The axial direction of the connecting hole 233 is not parallel to the installation and travel direction of the mounting device 2. The locking block 22 includes a rotating part 221, which is rotatably connected to the connecting hole 233.

[0054] Specifically, the connecting block 23 is fixed to the mounting housing 21 by bolts, the connecting hole 233 is a through hole, and the axial direction is set perpendicular to the installation and travel direction of the mounting device 2. The rotating part 221 of the locking block 22 is a long rod, which passes through the through hole to realize the rotational movement of the locking block 22.

[0055] This invention achieves stable switching between locked and unlocked states for the locking block 22 by setting the axial direction of the connecting hole 233 of the connecting block 23 to the installation and travel direction of the mounting device 2. This is achieved in conjunction with the rotatable connection between the rotating part 221 of the locking block 22 and the connecting hole 233. This allows the locking block 22 to reliably rotate in a predetermined direction when subjected to force, avoiding jamming or offset and ensuring a tight fit between the mounting device 2 and the external connection structure. At the same time, the non-parallel layout optimizes the movement trajectory of the locking mechanism and reduces operating resistance. The fixed installation method of the connecting block 23 enhances the overall structural rigidity, prevents shaking during locking, and improves the vibration resistance of the vehicle desktop when the vehicle is in motion.

[0056] In some embodiments, combined with Figure 4 and Figure 5 As shown, the locking block 22 also includes a locking buckle 222, and the external structure includes a locking groove 5. The locking buckle 222 is located on the side of the locking block 22 away from the connecting block 23 along the length direction of the locking block 22, and the locking buckle 222 is adapted to cooperate with the locking groove 5.

[0057] Specifically, the locking buckle 222 is a protrusion at one end of the locking block 22, and the locking groove 5 is a groove that adapts to the protrusion.

[0058] This invention improves the locking reliability of the mounting device 2 by setting a locking buckle 222 at the end of the locking block 22 away from the connecting block 23, so that it can precisely match the locking groove 5 of the external structure. The layout of the locking buckle 222 along the length of the locking block 22 utilizes the lever principle. When the locking block 22 is in the locked state, the locking buckle 222 and the locking groove 5 form a stable fastening structure, which can effectively resist the vibration and impact during vehicle operation. It is suitable for maintaining the stability of the vehicle desktop in bumpy driving environments, significantly improving the safety and ease of use.

[0059] In some embodiments, combined with Figure 4 and Figure 5 As shown, the connecting block 23 also includes a plug-in portion 231 and a mounting hole 232, and the unlocking block 24 includes a plug-in groove and a button 242. The length direction of the plug-in groove 241 is parallel to the length direction of the plug-in portion 231, and the plug-in groove 241 cooperates with the plug-in portion 231.

[0060] Specifically, the plug-in parts 231 are distributed on both sides of the connecting block 23, and the plug-in grooves 241 cooperate with the plug-in parts 231 on both sides. The plug-in grooves 241 are long grooves, and the plug-in parts 231 are long rods adapted to the shape of the grooves.

[0061] This invention ensures that the unlocking block 24 slides smoothly along a predetermined trajectory by engaging the insertion part 231 of the connecting block 23 with the insertion slot of the unlocking block 24, preventing deviation or jamming during operation. The parallel alignment design of the insertion slot 241 and the insertion part 231 simplifies the assembly process and enhances structural strength. The engagement of the insertion part 231 and the insertion slot not only restricts the degree of freedom of movement of the unlocking block 24 but also provides linear guidance for the unlocking process, making the switching of the locking state smoother and more reliable.

[0062] In some embodiments, combined with Figure 4 and Figure 5 As shown, the connecting block 23 also includes a first abutting part 234, and the locking block 22 also includes a second abutting part 223. When the insertion part 231 and the insertion groove 241 have a tendency to slide closer to each other, the first abutting part 234 and the second abutting part 223 that are in contact with the unlocking block 24 and the locking block 22 generate an abutting force, so that the locking buckle 222 has a tendency to move away from the locking groove 5 with the rotating part 221 as the axis. The mounting device 2 also includes a first elastic member 25. The connecting block 23 has a mounting hole 232. The length direction of the first elastic member 25 is parallel to the length direction of the insertion groove 241. One end of the first elastic member 25 abuts against the unlocking block 24, and the other end is disposed in the mounting hole 232.

[0063] Specifically, the first abutting part 234 and the second abutting part 223 are inclined surfaces that abut against each other, and the first elastic element 25 is a return spring. When the abutting force between the first abutting part 234 and the second abutting part 223 disappears, the spring returns to the locking block 22.

[0064] This invention utilizes the cooperation between the first abutting part 234 and the second abutting part 223 to generate an abutting force when the unlocking block 24 slides, causing the locking buckle 222 to disengage from the locking slot 5 around the rotating part 221, thus achieving the unlocking function. The first elastic member 25, positioned parallel to the insertion slot 241, provides a stable reset force and is also limited by the mounting hole 232 to ensure that the elastic member does not skew, allowing the unlocking block 24 to automatically return to its locked position and maintain the locked state, thereby improving the ease of operation and safety stability of the vehicle desktop.

[0065] In some embodiments, combined with Figure 4 and Figure 5 As shown, the mounting device 2 also includes a second elastic member 27, one end of which abuts against the mounting housing 21, and the other end of which abuts against the locking block 22 on the side of the locking block 22 close to the connecting block 23 along the length direction of the locking block 22.

[0066] The second elastic element 27 is a reset spring. When the first abutting part 234 and the second abutting part 223 come into contact, the second elastic element 27 is compressed and rotated by the rotating part 221 to achieve the unlocking function.

[0067] By adding a second elastic element 27, this utility model applies a continuous elastic force to the side of the locking block 22 near the connecting block 23, so that the locking buckle 222 and the locking groove 5 always maintain a tight engagement, thereby improving the stability of the locking state.

[0068] In some embodiments, combined with Figure 8 As shown, the first adjustment part 32 includes at least a first connecting part 321 and a plurality of adjusting grooves 322. The first connecting part 321 is rotatably connected to one end of the connecting frame 34, and the adjusting grooves 322 are adapted to fix the adjusting rod 31. The second adjustment part 33 includes at least a second connecting part 332, and the second connecting part 332 is rotatably connected to the other end of the connecting frame 34.

[0069] It is worth noting that there are multiple adjustment grooves 322, each corresponding to an adjustment angle, and the adjustment rod 31 is suitable for being fixed in the adjustment groove 322.

[0070] This invention achieves precise adjustment of the tabletop angle by using multiple adjustment grooves 322 of the first adjustment part 32 in conjunction with the adjustment rod 31. Users can flexibly select different settings according to their needs to meet diverse usage scenarios. The first connecting part 321 and the second connecting part 332 are rotatably connected to both ends of the connecting frame 34 to form a stable support structure, maintaining balanced force during adjustment. The stepped design of the adjustment grooves 322 allows the adjustment rod 31 to be securely engaged in different positions, ensuring that each angle is firmly locked and effectively resisting vibrations and impacts during vehicle operation.

[0071] In some embodiments, combined with Figure 8 As shown, in an optional embodiment, the first adjustment part 32 further includes a slot 323, and the second adjustment part 33 further includes a block 331 and a pressing plate 333. The slot 323 is slidably connected to the block 331. The pressing plate 333 is adapted to rotate about the second connecting part 332 as an axis in a direction closer to the tabletop 1. The block 331 is adapted to rotate about the second connecting part 332 as an axis in a direction away from the tabletop 1. The slot 323 is adapted to rotate about the first connecting part 321 as an axis in a direction away from the tabletop 1.

[0072] It is worth noting that when the first adjustment part 32 and the second adjustment part 33 rotate, the slot 323 and the block 331 change from the connected state to the disconnected state. At this time, there is enough adjustment space above the adjustment groove 322 so that the adjustment rod 31 can be engaged in another adjustment groove 322. When the slot 323 and the block 331 change from the disconnected state to the connected state, the adjustment space above the adjustment groove 322 is compressed, and the adjustment rod 31 is fixed in the adjustment groove 322.

[0073] This invention achieves a quick angle adjustment function for the tabletop 1 by using a sliding connection design between the slot 323 and the locking block 331, combined with the lever operation structure of the pressing plate 333. When the pressing plate 333 is pressed down with the second connecting part 332 as the axis, it drives the locking block 331 to rotate synchronously and disengage from the slot 323, allowing the tabletop 1 to be freely adjusted in angle. After releasing the pressing plate 333, the locking block 331 automatically re-engages and locks with the slot 323 under the elastic reset action, improving the convenience of adjustment. The cooperation design between the slot 323 and the locking block 331 produces a self-tightening effect when locked, ensuring that the tabletop 1 can obtain stable support at different angles and effectively resist vehicle bumps.

[0074] In some embodiments, combined with Figure 8As shown, the connecting frame 34 has a sliding groove 341 and a third elastic element 342. The sliding groove 341 is suitable for accommodating the adjusting rod 31, and the sliding groove 341 cooperates with the adjusting groove 322 to fix the adjusting rod 31. This invention achieves precise positioning and reliable fixing of the adjusting rod 31 through the cooperation structure of the sliding groove 341 and the adjusting groove 322 of the connecting frame 34, making the angle adjustment of the tabletop 1 more stable and easier to operate. The design of the sliding groove 341 provides a clear movement trajectory for the adjusting rod 31, avoiding deviation or shaking during the adjustment process; the third elastic element 342 continuously applies pressure to ensure that the adjusting rod 31 and the adjusting groove 322 are tightly engaged, preventing accidental loosening caused by vehicle bumps.

[0075] Specifically, the third elastic element 342 is a return spring. In the initial state, the first adjusting part 32 and the second adjusting part 33 are kept in a mating connection by the pressure applied by the return spring. When the return spring is subjected to external force that changes the connection state of the first adjusting part 32 and the second adjusting part 33, the return spring will apply a reset pressure to the first adjusting part 32 and the second adjusting part 33. When the external force disappears, the first adjusting part 32 and the second adjusting part 33 are re-maturing and connected.

[0076] Specifically, the third elastic element 342 is respectively disposed at the rotatable connection between the first connecting part 321 and the connecting frame 34 and the rotatable connection between the second connecting part 332 and the connecting frame 34, suitable for resetting the first adjusting part 32 and the second adjusting part 33. This invention, by providing the third elastic element 342 at each of the two rotatable connections, enables the first adjusting part 32 and the second adjusting part 33 to have an automatic reset function, improving the convenience and stability of angle adjustment. The symmetrical arrangement of the third elastic element 342 provides a balanced reset force for the adjusting mechanism, ensuring that the tabletop 1 can automatically return to its initial position, simplifying the operation process.

[0077] The specific workflow is as follows:

[0078] The process of inserting and removing the car desktop from the seat back:

[0079] When the car desktop is inserted into the seat back, bring the car desktop close to the slot on the seat back. The magnetic block 26 in the mounting device 2 interacts with the magnetic block 26 in the slot to open the sealing cover of the slot. At this time, the car desktop can be inserted into the slot. When the car desktop is fully inserted into the slot, the locking buckle 222 is pushed up by the inner wall of the slot. When the locking buckle 222 and the locking slot 5 reach the mating position, the second elastic element 27 resets the locking buckle 222, so that the locking buckle 222 and the locking slot 5 are mated, so that the car desktop can be quickly inserted into the slot on the seat back.

[0080] When removing the vehicle desktop from the seat back, the button 242 of the unlocking block 24 needs to be pressed. The button 242 uses the insertion slot 241 and the insertion part 231 to push the connecting block 23 so that the first abutting part 234 of the connecting block 23 and the second abutting part 223 of the locking block 22 interact. This causes the locking block 22 to rotate through the rotating part 221, thereby moving the locking buckle 222 away from the locking slot 5. Under the action of the second elastic member 27, when the external force disappears, according to the lever action, the locking buckle 222 will return to the locking position with the locking slot 5.

[0081] The process of adjusting the angle of the in-vehicle desktop:

[0082] First, press the pressing plate 333 of the second adjustment part 33 to make the second adjustment part 33 rotate around the second connecting part 332. Since the locking block 331 and the locking groove 323 cooperate with each other, when the second adjustment part 33 rotates, the locking block 331 will drive the locking groove 323 to move at the same time. At this time, the first adjustment part 32 is suitable to move around the first connecting part 321. The first adjustment part 32 and the second adjustment part 33 form a triangular structure with the connecting frame 34, so that there is an adjustment space between the first adjustment part 32 and the connecting frame 34, which is suitable for changing the position of the adjustment rod 31 and locking it into different adjustment grooves 322 to adjust the angle of the vehicle tabletop. When it is locked into the appropriate adjustment groove 322, the pressing plate 333 can be released to realize the angle adjustment process.

[0083] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
