[0002] Some vehicles are equipped with onboard tables. These tables consist of a tabletop and a support rod. The support rod is vertically mounted on the vehicle floor, and the tabletop is mounted on the support rod. In some designs, the tabletop is configured to rotate around the axis of the support rod, allowing the user to turn it as needed. However, the distance between the tabletop and the user cannot change while the tabletop is rotating, which negatively impacts the user experience. Summary of the Invention

[0003] To address the aforementioned technical problems, a first aspect of this application provides a bracket assembly for a vehicle-mounted table. The bracket assembly includes a connecting base and a support rod assembly. The connecting base includes a connecting shaft, the axial direction of which is parallel to the vertical direction. The support rod assembly includes a first rod assembly arranged horizontally and a second rod assembly arranged vertically. The connecting shaft is adapted to connect to a first end of the first rod assembly, the second rod assembly is adapted to be mounted at a second end of the first rod assembly, and the support rod assembly is adapted to rotate about the axial direction of the connecting shaft.

[0004] In one embodiment, the connector further includes a horizontally oriented annular toothed plate surrounding the connector shaft. The first rod assembly includes a first locking seat assembly; the first locking seat assembly is adapted to engage with the toothed plate such that the support rod assembly and the connector can rotate synchronously about the axial direction of the connector shaft, and the first locking seat assembly is adapted to disengage from the toothed plate to allow the support rod assembly to rotate relative to the connector shaft about the axial direction of the connector shaft.

[0005] In one embodiment, when the second rod assembly is mounted at the second end of the first rod body, the first lock seat assembly is driven by the second rod assembly to separate from the toothed plate; and when the second rod assembly is removed from the second end of the first rod body, the first lock seat assembly engages with the toothed plate.

[0006] In one embodiment, a first rod assembly includes a first rod body defining a first mounting space. A connecting shaft is adapted to connect to a first end of the first rod body, and a second rod assembly is adapted to be mounted at a second end of the first rod body. A first lock seat assembly is disposed within the first mounting space and includes a first lock seat and a first lock bar. The first lock bar extends along the length of the first rod body and is hinged to the first rod body. The first lock seat is mounted on the first lock bar and engages or disengages from a toothed plate as the first lock bar rotates.

[0007] In one embodiment, the first lock seat assembly further includes a first elastic element connected between the first lever body and the first lock lever. When the first lock seat is separated from the toothed plate, the first elastic element is tensioned; and the first elastic element is adapted to return to its original position and drive the first lock lever to rotate, thereby engaging the first lock seat with the toothed plate.

[0008] In one embodiment, the connector further includes a horizontally oriented annular toothed plate surrounding the connecting shaft. The first rod assembly also includes a second locking assembly. The second locking assembly is adapted to engage with the toothed plate to allow the support rod assembly and the connector to rotate synchronously about the axial direction of the connecting shaft, and the second locking assembly is adapted to disengage from the toothed plate to allow the support rod assembly to rotate relative to the connector about the axial direction of the connecting shaft.

[0009] In one embodiment, the first lever assembly includes a first lever body defining a first mounting space. A second lock seat assembly is disposed within the first mounting space and includes a second lock seat and a second lock bar. The second lock bar extends along the length of the first lever body and is hinged to the first lever body. The second lock seat is mounted on the second lock bar and is adapted to engage or disengage from a toothed plate as the second lock bar rotates.

[0010] In one embodiment, the second lock seat assembly further includes a second elastic element connected between the first rod body and the second lock rod. When the second lock seat engages with the toothed plate, the second elastic element is tensioned, and the second elastic element is adapted to return to its original position and drive the second lock rod to rotate, thereby disengaging the second lock seat from the toothed plate.

[0011] In one embodiment, the second lock seat assembly further includes a first button having a first drive ramp; the second lock lever has a second drive ramp that matches the first drive ramp. The first button is adapted to move toward the interior of the first lever body, such that the first drive ramp of the first button pushes the second lock lever to rotate, thereby driving the second lock seat to engage with the toothed plate.

[0012] In one embodiment, the connector further includes a horizontally oriented support plate and a pressure ring disposed above the support plate, forming an annular mounting groove between the support plate and the pressure ring. The connecting shaft includes a shaft body and a flange extending radially outward from the shaft body. The shaft body extends vertically through the pressure ring, and the flange is disposed within the mounting groove and adapted to rotate circumferentially relative to the mounting groove.

[0013] In one embodiment, the connector further includes a first mounting plate having a plurality of first connecting teeth arranged in a ring around the axial direction of the connecting shaft. The bracket assembly also includes a fixedly disposed base. The base includes a second mounting plate having a plurality of second connecting teeth arranged to correspond to the plurality of first connecting teeth. The connector is adapted to rotate relative to the base about the axial direction of the connecting shaft such that each first connecting tooth engages with a corresponding second connecting tooth.

[0014] In one embodiment, one of the first mounting plate and the second mounting plate is provided with a positioning hole, and the other is provided with a positioning protrusion corresponding to the positioning hole. When the first connecting tooth and the second connecting tooth engage, the positioning protrusion engages with the positioning hole.

[0015] In one embodiment, a transition rod is provided at the second end of the first rod assembly, the transition rod being configured with a first connecting structure. The second rod assembly includes a connecting component, the connecting component including a third locking rod, and the third locking rod being configured with a second connecting structure that matches the first connecting structure. When the second rod assembly is mounted at the second end of the first rod assembly, the second connecting structure engages with the first connecting structure, and the second connecting structure is adapted to disengage from the first connecting structure, so that the second rod assembly can be detached from the first rod assembly.

[0016] In one embodiment, the second rod assembly includes a second rod body defining a second mounting space. A connecting assembly is disposed within the second mounting space and includes a mounting bracket. A third locking rod extends vertically and is hinged to the mounting bracket, such that the third locking rod is adapted to rotate and drive the second connecting structure to engage or disengage from the first connecting structure.

[0017] In one embodiment, the connecting assembly further includes a second button slidably mounted on a mounting bracket, the second button extending from the outside of the second rod body to the inside of the second rod body in a lateral direction and adapted to actuate a third locking lever.

[0018] In one embodiment, the connecting assembly further includes a torsion spring disposed on the third locking rod, with a first end abutting against the third locking rod and a second end abutting against the mounting bracket. The torsion spring is tensioned after the second connecting structure engages with the first connecting structure, and returns to its original position after the second connecting structure separates from the first connecting structure.

[0019] A second aspect of this application discloses a vehicle-mounted table. The vehicle-mounted table includes a tabletop and a support assembly as described above. The tabletop is mounted at the end of a second rod assembly remote from the first rod assembly.

[0020] The beneficial effects of this application are as follows: When using the vehicle-mounted table according to this application, the user can push or pull the tabletop to rotate around the axial direction of the connecting shaft. In addition, when the tabletop rotates around the axial direction of the connecting shaft, the horizontal position of the tabletop also changes, and the tabletop moves away from or closer to the user, which helps to improve the user's experience of using the vehicle-mounted table.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] Figure 1 A vehicle 1 according to one embodiment of this application is schematically shown. Figure 1 As shown, the interior of vehicle 1 includes front seats 11, rear seats 12, and a table 2 positioned between the front seats 11 and the rear seats 12. The table 2 is removable, allowing users to install or remove it for storage as needed. It should be understood that for other types of vehicles, the table can also be placed in other locations within the vehicle's interior, which will not be elaborated upon here.

[0041] The following describes the vehicle-mounted table 2.

[0042] Reference Figure 2 and Figure 3 The vehicle-mounted table 2 includes a tabletop 201 and a support assembly 202. The tabletop 201 is supported by the support assembly 202 in the vertical direction Z.

[0043] The bracket assembly 202 includes a connector 203, a base 204, and a support rod assembly 205. The base 204 is typically pre-fixed to the vehicle floor. The connector 203 is connected to the base 204, and the support rod assembly 205 is connected to the connector 203.

[0044] Reference Figure 3 and Figure 5 The connecting seat 203 is generally circular and has a connecting shaft 32 located at the center of the circle. The connecting shaft 32 extends generally in the vertical direction Z (in other words, the axial direction of the connecting shaft 32 is parallel to the vertical direction Z).

[0045] The support rod assembly 205 includes a first rod assembly 501 generally arranged along the horizontal direction X (the horizontal direction X is generally perpendicular to the vertical direction Z) and a second rod assembly 502 arranged along the vertical direction Z. (See reference...) Figure 3 and Figure 8 The connecting seat 203 is located at the first end of the first rod assembly 501, and the connecting shaft 32 is connected to the first end of the first rod assembly 501. The second rod assembly 502 is installed at the second end of the first rod assembly 501 and is positioned above the first rod assembly 501 in the vertical direction Z (e.g., Figure 2 (As shown). The tabletop 201 is mounted at the end of the second rod assembly 502 away from the first rod assembly 501. It should also be noted that in the vehicle-mounted table 2, the second rod assembly 502 is spaced apart from the connecting shaft 32 in the horizontal direction X.

[0046] The first lever assembly 501 is rotatable about the axial direction of the connecting shaft 32. Thus, when using the vehicle table 2, the user can push or pull the tabletop 201 to rotate about the axial direction of the connecting shaft 32 as needed. Furthermore, since the second lever assembly 502 is spaced apart from the connecting shaft 32 in the horizontal direction X, the position of the tabletop 201 in the horizontal direction X also changes as it rotates about the connecting shaft 32, and the tabletop 201 moves away from or closer to the user (for example, the tabletop 201 may move away from or closer to the user along the width of the vehicle, or along the length of the vehicle). This helps improve the user experience when using the vehicle table 2.

[0047] like Figure 5 As shown, the connecting seat 203 also has a support plate 321 generally arranged in the horizontal direction X and a pressure ring 322 disposed above the support plate 321. An annular mounting groove 323 is formed between the support plate 321 and the pressure ring 322. The connecting shaft 32 includes a shaft body 324 and a flange 325 extending radially outward from the shaft body 324. The shaft body 324 extends in the vertical direction Z through the pressure ring 322 and is fixedly connected to the first end of the first rod assembly 501. The flange 325 is disposed in the mounting groove 323 and is circumferentially rotatable relative to the mounting groove 323. In this way, the first rod assembly 501 (and the support rod assembly 205) can rotate together with the connecting shaft 32 about the axial direction of the connecting shaft 32. Of course, depending on the actual situation, the connecting shaft can also be set to not rotate, and the first rod assembly can be set to rotate relative to the connecting shaft, which will not be described in detail here.

[0048] The connection between connector 203 and base 204 will now be described.

[0049] For example Figure 5As shown, the connecting seat 203 also has a first mounting plate 31. For example, the first mounting plate 31 includes a cylindrical portion 313 and a plurality of first connecting teeth 311 extending radially outward from the cylindrical portion 313. The cylindrical portion 313 is assembled with a pressure ring 322. The first connecting teeth 311 and the connecting shaft 32 are located on both sides of the bearing plate 321. The cylindrical portion 313 and the connecting shaft 32 are substantially coaxial, and the first connecting teeth 311 are arranged in a ring around the axial direction of the connecting shaft 32 (e.g., Figure 4 (As shown).

[0050] like Figure 6 As shown, the base 204 has a second mounting plate 42. For example, the second mounting plate 42 is annular. The circumferential inner edge of the second mounting plate 42 is provided with a plurality of second connecting teeth 421. These second connecting teeth 421 extend radially inward and correspond to the first connecting teeth 311.

[0051] When it is necessary to connect the connector 203 to the base 204, firstly, insert the first connecting teeth 311 into the gaps between adjacent second connecting teeth 421. Then, rotate the connector 203 relative to the base 204 in the positive direction (e.g., clockwise) around the axial direction of the connecting shaft 32, so that the first connecting teeth 311 and the second connecting teeth 421 engage together in the vertical direction Z. In this way, the connector 203 and the base 204 are stably connected together, thus completing the assembly of the vehicle-mounted table.

[0052] When it is necessary to separate the connector 203 from the base 204, the connector 203 is rotated in the opposite direction (e.g., counterclockwise) relative to the base 204 to disengage the first connecting tooth 311 from the second connecting tooth 421 in the circumferential direction. This allows the connector 203 to be detached from the base 204. In some embodiments, the surface of the first connecting tooth that engages with the second connecting tooth is configured as a bevel and / or the surface of the second connecting tooth that engages with the first connecting tooth is configured as a bevel. Thus, as the connector rotates forward, the first connecting tooth and the second connecting tooth engage more and more tightly. When the connector is rotated in the opposite direction, the first connecting tooth and the second connecting tooth can quickly disengage, thereby completing the disassembly of the vehicle-mounted table.

[0053] Also refer to Figure 4 and Figure 6The first mounting plate 31 is provided with multiple positioning protrusions 312. For example, these positioning protrusions 312 are arranged around the axial direction of the connecting shaft 32. The second mounting plate 42 is provided with multiple positioning holes 422 corresponding to the positioning protrusions 312. When the first connecting tooth 311 and the second connecting tooth 421 engage together, the positioning protrusions 312 and the positioning holes 422 also engage together. In this way, the connection between the connecting seat 203 and the base 204 is more stable. Of course, depending on the actual situation, the positioning protrusions can also be provided on the second mounting plate, and the positioning holes can be provided on the first mounting plate accordingly, which will not be elaborated here.

[0054] In one embodiment, a sensor (not shown) is provided on the base. The sensor is used to detect whether the connector is connected to the base, thereby providing information to the vehicle's main unit regarding whether the on-board table is assembled. In one embodiment, the sensor is a Hall sensor, and a magnet matching the Hall sensor is provided on the connector or the first rod assembly.

[0055] For example Figure 5 As shown, the connecting seat 203 also has a toothed plate 33 arranged along the horizontal direction X, and the toothed plate 33 and the connecting shaft 32 are located on the same side of the bearing plate 321. It should be understood that, depending on the actual situation, the connecting seat may also include other components to fix the toothed plate, the pressure ring, the bearing plate and the first mounting plate, which will not be described in detail here.

[0056] The toothed plate 33 is annular, and the connecting shaft 32 extends through the toothed plate 33 in the vertical direction Z. Multiple teeth are constructed on the end face of the toothed plate 33 opposite to the bearing plate 321. These locking teeth are arranged in the circumferential direction of the toothed plate 33 (that is, these teeth are arranged in annular around the axial direction of the connecting shaft 32).

[0057] Reference Figure 7 and Figure 8 The first rod assembly 501 includes a first rod body 541 defining a first mounting space 546 and a first lock seat assembly 511 disposed within the first mounting space 546. In this configuration, the connecting seat 203 is fixedly connected to a first end of the first rod body 541, and the second rod assembly 502 is detachably connected to a second end of the first rod body 541.

[0058] The first lock seat assembly 511 includes a first lock seat 513 and a first lock bar 514. For example... Figure 9 As shown, the first lock seat 513 is constructed with a first locking tooth 515 that matches the teeth of the toothed plate 33, allowing the first lock seat 513 to engage or disengage from the toothed plate 33. Furthermore... Figure 8As shown, the first locking bar 514 extends generally along the length of the first bar body 541 and has a first mounting portion 514a and a first connecting portion 514b and a first driving portion 514c located on both sides of the first mounting portion 514a. For example, the first connecting portion 514b and the first driving portion 514c are located at both ends of the first locking bar 514. The first mounting portion 514a is hinged to the first bar body 541 so that the first locking bar 514 can rotate about the first connecting portion 514a. The first connecting portion 514b is connected to the first locking seat 513. The first driving portion 514c is located at the second end of the first bar body 541. When the second bar assembly 502 is installed at the second end of the first bar body 541, the first driving portion 514c is pushed by the second bar assembly 502, causing the first bar body 541 to rotate. It should be understood that, depending on the actual situation, the first driving portion can also be pushed in other ways to cause the first bar body to rotate, which will not be described in detail here.

[0059] When assembling the vehicle-mounted table 2, the connecting seat 203 is first placed on the base 204, and the first connecting teeth 311 on the connecting seat 203 are inserted into the gaps between the second connecting teeth 421 on the base 204 (as described above). At this time, the second rod assembly 502 has not yet been installed at the second end of the first rod body 541. The first locking seat 513 engages with the toothed plate 33 of the connecting seat 203, so that the first rod assembly 501 and the connecting seat 203 cannot rotate relative to each other, but can only rotate synchronously around the axial direction of the connecting shaft 32. In this way, the user can rotate the first rod body 541 forward (for example, by pushing or pulling the second end of the first rod body 541) to make the connecting seat 203 rotate forward relative to the base 204, and the first connecting teeth 311 on the connecting seat 203 and the second connecting teeth 421 on the base 204 are firmly engaged together, realizing the connection between the connecting seat 203 and the base 204. Because the first rod body 541 (or the first rod assembly 501) has an appropriate length, the user can use a small force to push or pull the second end of the first rod body 541 to firmly connect the connecting seat 203 and the base 204 together, which helps to improve the user's experience of using the vehicle table.

[0060] Next, at least a portion of the second lever assembly 502 is positioned at the second end of the first lever body 541. The first drive unit 514c is pushed by the second lever assembly 502, causing the first lever body 541 to rotate. The first connecting portion 514b of the first locking lever 514 drives the first locking seat 513 to move substantially in the vertical direction Z and separate from the toothed plate 33. In this way, the first lever assembly 501 and the connecting shaft 32 can rotate relative to the rest of the connecting seat 203 and the base 204. The user can rotate the tabletop 201 about the axial direction of the connecting shaft 32 as needed, and the support rod assembly 205 rotates accordingly about the axial direction of the connecting shaft 32.

[0061] It should be noted that when disassembling the vehicle table 2, the second rod assembly 502 can be removed from the first rod body 541 firstly, and the first locking seat 513 can be repositioned to engage with the toothed plate 33 accordingly. In this way, the user can rotate the first rod body 541 in the opposite direction, and the connecting seat 203 will rotate in the opposite direction relative to the base 204. This disengages the first connecting tooth 311 from the second connecting tooth 421 circumferentially, allowing the connecting seat 203 (and the first rod assembly 501) to be removed from the base 204. Similarly, because the first rod body 541 has an appropriate length, the user can disengage the first connecting tooth 311 from the second connecting tooth 421 circumferentially by pushing or pulling the second end of the first rod body 541 with relatively little force, which also helps improve the user experience of using the vehicle table.

[0062] It should be noted that since the teeth on the toothed plate 33 are arranged in a ring around the axial direction of the connecting shaft 32, the first locking seat 513 can always engage with the toothed plate 33 when the user rotates the table 201 around the axial direction of the connecting shaft 32. In this way, when the user removes the second rod assembly 502 from the first rod body 541 to disassemble the vehicle table 2, there is no need to pay special attention to the angle position of the table 201 (or the first rod assembly 501), which also facilitates the use of the vehicle table 2.

[0063] It should be understood that, in other embodiments, teeth may also be formed on the circumferential surface of the toothed plate. In this case, the first locking seat moves in the radial direction of the toothed plate to engage or disengage from the toothed plate, which will not be described further here.

[0064] like Figure 10 As shown, the first lock seat assembly 511 also includes a first elastic element 519. For example, the first elastic element is a tension spring. The first elastic element 519 is connected between the first rod body 541 and the first lock rod 514.

[0065] During the assembly of the vehicle-mounted table 2, before the second rod assembly 502 is installed at the second end of the first rod body 541, the first elastic member 519 keeps the first locking seat 513 engaged with the toothed plate 33. When the second rod assembly 502 is installed at the second end of the first rod body 541, the first locking seat 513 separates from the toothed plate 33, and the first elastic member 519 is tensioned.

[0066] During the disassembly of the vehicle-mounted table 2, after the second rod assembly 502 is detached from the second end of the first rod body 541, the shape of the first elastic element 519 is restored and drives the first locking rod 514 to rotate, so that the first locking seat 513 and the toothed plate 33 automatically return to engagement. This facilitates the user's assembly and disassembly of the vehicle-mounted table 2.

[0067] For example Figure 8As shown, the first locking bar 514 includes a first bar segment 516 and a second bar segment 517. One end of the first bar segment 516 and one end of the second bar segment 517 are hinged together. Additionally, a first mounting portion 514a and a first connecting portion 514b are constructed on the first bar segment 516, and a first driving portion 514c is constructed on the second bar segment 517. A first elastic member 519 connects the second bar segment 517 and the first bar body 541. The length and shape of the first bar segment 516 and the second bar segment 517 can be determined according to actual conditions so that the first locking bar 514 can be easily installed in confined spaces. Of course, depending on actual conditions, the first elastic member can also be connected between the first bar segment and the first bar body. Furthermore, depending on actual conditions, the first locking bar can also include more bar segments, or it can be composed of a single bar.

[0068] Reference Figure 7 and Figure 11 The first rod assembly 501 also includes a second lock seat assembly 521 disposed within the first mounting space 546. The second lock seat assembly 521 is spaced apart from the first lock seat assembly 511 in the lateral direction of the first rod body 541.

[0069] The second lock seat assembly 521 includes a second lock seat 523 and a second lock bar 524. For example... Figure 12 As shown, the second lock seat 523 is configured with a second locking tooth 525 that matches the teeth on the toothed plate 33, allowing the second lock seat 523 to engage or disengage from the toothed plate 33. The second lock bar 524 extends substantially along the length of the first bar body 541 (i.e., the second lock bar 524 is substantially parallel to the first lock bar 514) and has a second mounting portion 524a and second connecting portions 524b and second driving portions 524c located on both sides of the second mounting portion 524a. For example, the second connecting portions 524b and the second driving portions 524c are located at both ends of the second lock bar 524. The second mounting portion 524a is hinged to the first bar body 541 so that the second lock bar 524 rotates about the second connecting portion 524a. The second connecting portion 524b is connected to the second lock seat 523.

[0070] Also refer to Figure 12 and Figure 13 The second drive portion 524c of the second locking lever 524 is configured with a second drive ramp 522. The second lock seat assembly 521 also includes a first button 526. For example, the first button 526 includes a first button body 526a and a first push block 526b connected to the first button body 526a. At least a portion of the first button body 526a is located outside the first lever body 541. The first push block 526b extends from the first button body 526a toward the second drive portion 524c of the second locking lever 524 and is configured with a first drive ramp 526c that matches the second drive ramp 522. The first drive ramp 526c and the second drive ramp 522 are slidably engaged together.

[0071] During and after the assembly of the vehicle-mounted table 2, the second locking seat 523 remains separate from the toothed plate 33. This ensures that the second locking seat assembly 521 does not obstruct the rotation of the tabletop 201 when the vehicle-mounted table 2 is in use.

[0072] During use of the vehicle-mounted table 2, the connecting seat 203 may rotate in the opposite direction relative to the base 204 for some reason, causing the connection between the connecting seat 203 and the base 204 to become loose. In this case, the user presses the first button 526 towards the inside of the first rod body 541, causing the first driving ramp 526c of the first push block 526b to push the second driving ramp 522 (or the second driving part 524c) of the second locking rod 524 to move upward in the vertical direction Z. The second locking rod 524 rotates accordingly, causing the second locking seat 523 to engage with the toothed plate 33. Thus, the first rod assembly 501 and the connecting seat 203 cannot rotate relative to each other, but can only rotate synchronously around the axial direction of the connecting shaft 32. In this way, without removing the second rod assembly 502 from the first rod body 541, the connecting seat 203 can still be rotated in the forward direction relative to the base 204 and reconnected stably to the base 204 by rotating the first rod body 541 in the forward direction. After the connecting seat 203 and the base 204 are re-securely connected, the first button 526 is moved outward from the first rod body 541, the second drive part 524c of the second locking rod 524 moves downward in the vertical direction Z, the second locking rod 524 rotates accordingly, and the second locking seat 523 separates from the toothed plate 33. In this way, the first rod assembly 501 and the connecting shaft 32 can rotate relative to the rest of the connecting seat 203 and the base 204, and the user can rotate the tabletop 201 about the axial direction of the connecting shaft 32 as needed.

[0073] For example Figure 12 As shown, the second lock seat assembly 521 also includes a second elastic element 529 connected between the first rod body 541 and the second lock rod 524. For example, the second elastic element is a compression spring.

[0074] During the assembly and use of the vehicle-mounted table 2, the second elastic element 529 keeps the second locking seat 523 separated from the toothed plate 33.

[0075] When the user presses the first button 526 towards the inside of the first rod body 541, causing the second locking rod 524 to rotate until the second locking seat 523 engages with the toothed plate 33, the second elastic member 529 is compressed and tensioned by the second locking rod 524. After releasing the first button 526, the second elastic member 529 returns to its original position and drives the second locking rod 524 to rotate until the second locking seat 523 separates from the toothed plate 33. The first button 526 is pushed outward by the second driving part 524c of the second locking rod 524 to reset the first button 526. In other words, by using the second elastic member 529, after releasing the first button 526, the second locking seat 523 and the toothed plate 33 can automatically separate and the first button 526 can automatically reset, which further facilitates the use of the vehicle table 2.

[0076] It should be noted that when the first lever assembly 501 includes a first lock seat assembly 511 and a second lock seat assembly 521, when disassembling the vehicle table 2, the second lever assembly 502 is still first removed from the second end of the first lever body 541 so that the first lock seat 513 and the toothed plate 33 are re-engaged. Then, the first lever body 541 is rotated in the opposite direction to remove the connecting seat 203 from the base 204.

[0077] The connection between the first rod assembly 501 and the second rod assembly 502 will now be described.

[0078] Reference Figure 3 and Figure 14 A connecting hole 545 extending vertically in the Z direction is provided at the second end of the first rod body 541, and an adapter rod 543 is provided within the connecting hole 545. For example, the adapter rod extends generally in the vertical Z direction and is fixedly connected to the first rod body. At least a portion of the second rod assembly 502 is inserted into the connecting hole 545 and connected to the adapter rod 543. The connecting hole 545 guides the installation of the second rod assembly 502 on the first rod assembly 501, facilitating the installation of the second rod assembly 502. The connecting hole 545 also serves to hold the second rod assembly 502, helping to improve the stability of the second rod assembly 502. In one embodiment, a connecting sleeve extending generally in the vertical Z direction may also be provided at the connecting hole, the connecting sleeve surrounding the adapter rod. The second rod assembly is inserted into the connecting sleeve and connected to the adapter rod.

[0079] Reference Figure 14 , Figure 15 and Figure 16 The adapter rod 543 is constructed with a first connecting structure 544. For example, the first connecting structure is a connecting groove.

[0080] The second rod assembly 502 includes a second rod body 542 defining a second mounting space 547 and a connecting assembly 55 disposed within the second mounting space 547. For example... Figure 15 and Figure 16 As shown, the connecting assembly 55 includes a mounting bracket 551, a third locking lever 552, and a second button 556.

[0081] Mounting bracket 551 is fixedly installed inside the second rod body 542 and has a channel 555 that runs through it in the vertical direction Z.

[0082] The second button 556 includes a second button body 556a and a second push block 556b. At least a portion of the second button body 556a is located outside the second rod body 542. The second push block 556b extends from the second button body 556a toward the interior of the second rod body 542 in the lateral direction (i.e., a direction substantially perpendicular to the axial direction of the second rod body) and is slidably engaged with a mounting bracket 551. In one embodiment, the mounting bracket 551 is provided with a groove 553 extending in the lateral direction of the second rod body 542, and the second push block 556b is provided with a rib (not shown) that matches the groove 553. The rib is slidably engaged within the groove 553. The groove 553 and the rib guide and constrain the sliding of the second push block 556b (or the second button 556) in the lateral direction of the second rod body 542, allowing the second button 556 to slide more smoothly. It should be understood that, depending on the actual situation, the slide can also be constructed on the second push block, and the ribs can be constructed on the mounting bracket accordingly, which will not be elaborated here.

[0083] The third locking rod 552 has a third mounting portion 552a and a third connecting portion 552b and a third driving portion 552c located on both sides of the third mounting portion 552a. For example, the third connecting portion and the third driving portion are the two ends of the third locking rod. The third locking rod 552 extends vertically Z through a channel 555 on the mounting frame 551. The third mounting portion 552a is hinged to the mounting frame 551. The third connecting portion 552b is located vertically Z below the third driving portion 552c and is configured with a second connecting structure 554 that matches the first connecting structure 544. For example, the second connecting structure is a connecting hook. The third driving portion 552c is hinged to the second push block 556b.

[0084] When the second rod assembly 502 is connected to the first rod assembly 501 in the vertical direction Z, the second connecting structure 554 on the third locking rod 552 will be connected to the first connecting structure 544 of the adapter rod 543 on the first rod body 541.

[0085] When it is necessary to detach the second lever assembly 502 from the first lever assembly 501, push the second button 556 toward the interior of the second lever body 542. The second push block 556b correspondingly pushes the third drive portion 552c of the third locking lever 552, causing the third locking lever 552 to rotate around the third mounting portion 552a, and the third connecting portion 552b of the third locking lever 552 separates from the adapter rod 543 (i.e., the second connecting structure 554 separates from the first connecting structure 544). Then, the second lever assembly 502 can be detached from the first lever assembly 501 in the vertical direction Z upwards.

[0086] In one embodiment, the connecting assembly 55 further includes a torsion spring 559 disposed on the third locking rod 552. A first end of the torsion spring 559 abuts against the third locking rod 552, and a second end abuts against the mounting bracket 551. After the second rod assembly 502 is assembled with the first rod assembly 501, the torsion spring 559 is in its initial state, and the adapter rod 543 and the third locking rod 552 (or the first connecting structure 544 and the second connecting structure 554) are connected together. When it is necessary to detach the second rod assembly 502 from the first rod assembly 501, the second button 556 pushes the third locking rod 552 to rotate, and the torsion spring 559 is tensioned. After the second rod assembly 502 is detached from the first rod assembly 501, the torsion spring 559 returns to its original position and drives the third locking rod 552 to automatically reset. This enables quick assembly and disassembly of the second rod assembly 502 and the first rod assembly 501, facilitating the user's use of the vehicle-mounted table 2.
