[0035] Refer to Figures 1 to 4, the keyboard tray 100 according to the first aspect embodiment of the present utility model includes a tray 102 and two sets of guide rail assemblies. The two sets of guide rail assemblies are installed on the tray 102 and are symmetrically arranged with respect to the symmetry axis of the tray 102. The tray 102 is configured to be switchable between an extended position and a retracted position through the two sets of guide rail assemblies; wherein, the guide rail assembly includes a guide rail 101 and a connecting rod 103. The guide rail 101 is installed on the tray 102. The connecting rod 103 has a connecting end 202 and a sliding end 203. The sliding end 203 is slidably connected to the guide rail 101 and can rotate relative to the guide rail 101. The connecting end 202 is rotatably connected to the tabletop 201. When the tray 102 is in the retracted position, the connecting end 202 and the tray 102 are spaced apart.

[0036] In some embodiments of the present utility model, the tray 102 can move in a first direction and move in a second direction to switch between an extended position and a retracted position. The first direction and the second direction are opposite. Refer to Figures 2 to 4 , in some embodiments of the present utility model, the first direction is the direction of forward and inward, and the second direction is the direction of backward and outward. The direction of the second reference line 205 mentioned below is the left-right direction.

[0037] Refer to Figure 8 , in the prior art, the guide rails 101 of the tray 102 are arranged on both sides of the tray 102 along the pushing and pulling direction. One end of the connecting end 202 is fixed to the tabletop 201, and the other end is directly arranged in the guide rail 101 of the tray 102. When the tray 102 is pushed inward to the topmost position, that is, the retracted position, the connecting end 202 is located at the bottommost end of the guide rail 101. At this time, the tray 102 cannot be pushed inward anymore, and the retraction stroke is small. It should be noted that there is no connecting rod 103 in the prior art. The connecting end 202 mentioned here is only for easy understanding. In fact, it should be a structure such as a slider of the guide rail 101 in the prior art. In the keyboard tray 100 of the embodiment of the present utility model, a connecting rod 103 is added between the connecting end 202 and the guide rail 101. By using the sliding end 203 of the connecting rod 103 to slide in the guide rail 101 and the connecting end 202 being rotatably connected to the tabletop 201, while realizing the function of pushing and pulling the tray 102, it can also make the tray 102 be spaced apart from the connecting end 202 in the first direction when the tray 102 is in the retracted position, and has a greater inward pushing stroke compared to the situation where the connecting end 202 is still located inside the tray 102 in the prior art when in the retracted position.

[0038] It should be noted that, refer to Figures 2 to 4, in some embodiments of the present utility model, the storage position is the extreme end where the tray 102 moves towards the first direction, and the tray 102 can no longer move relative to the tabletop 201 along the first direction. Specifically, in the usage scenario, when the tray 102 is in the storage position, the user does not need to use the keyboard tray 100, and the area of the tray 102 exposed outside the tabletop 201 is the smallest; the extended position is the extreme end where the tray 102 moves towards the second direction, and the tray 102 can no longer move relative to the tabletop 201 along the second direction. Specifically, in the usage scenario, when the tray 102 is in the extended position, the user needs to use the keyboard tray 100, and the area of the tray 102 exposed outside the tabletop 201 is the largest; and the intermediate position mentioned below refers to: Refer to Figure 3 , the tray 102 includes a first side 301 and a second side 302. The first side 301 and the second side 302 are arranged at intervals in sequence along the first direction. The first side 301 is the side closer to the user's torso during use. When the tray 102 is in the intermediate position, the connecting line of the two connecting ends 202, that is, the second reference line 205, is located between the first side 301 and the second side 302 in the first direction.

[0039] It should be noted that, refer to Figure 4 , in some embodiments of the present utility model, when the tray 102 is in the extended position, the connecting end 202 and the tray 102 are arranged at intervals in sequence along the second direction. In the prior art, when the tray 102 is pulled outwards to the extended position, the connecting end is at the topmost end of the guide rail 101. At this time, the tray 102 can no longer be pulled outwards, and the extension stroke is also small. And refer to Figure 4 , in some embodiments of the present utility model, the tray 102 has a larger outward movement stroke compared to the extended position in the prior art, which is more convenient for the user to use and meets the requirements of more scenarios.

[0040] It should be noted that, refer to Figure 1 and Figure 2, in some embodiments of the present utility model, the guide rail 101 is a hollow structure provided with a track groove. The connecting rod 103 is connected to the guide rail 101 by bolts and nuts, and the nut is arranged inside the guide rail 101 and jointly abuts against the sliding end 203 and the track with the head of the bolt, so as to realize the sliding of the connecting sliding end 203 relative to the guide rail 101 and the relative rotation between the two. Such a design is convenient for disassembly, and the tightness between the guide rail 101 and the connecting rod 103 can also be adjusted by rotating the bolt. When the tray 102 is in the required position, tightening the bolt can fix the position of the keyboard tray 100 relative to the table board 201, which is simple and effective. In some embodiments of the present utility model, the guide rail 101 may also include a guiding strip, and the sliding end 203 is arranged as a slider provided with a sliding groove, and the guiding strip of the guide rail is embedded in the sliding groove. When the guide rail 101 is in the form of a track groove, the minimum distance L2 between the guide rail 101 and the first reference line 204 mentioned below refers to the distance between the end of the track groove and the first reference line 204. When the guide rail 101 is in the form of a guiding strip, the minimum distance L2 between the guide rail 101 and the first reference line 204 refers to the distance between the end of the guiding strip and the first reference line 204. For example, the part where the guide rail 101 is connected to the tray 102 in the embodiments of the present utility model, or the protruding part in other embodiments is not within the scope of consideration of this distance.

[0041] Reference Figure 1 , in some embodiments of the present utility model, the symmetry axis of the two connecting rods 103 is the first reference line 204, the first reference line 204 extends along the first direction, the two guide rails 101 are symmetrically arranged based on the first reference line 204, and the guide rails 101 are straight. Along the first direction, the distance between the two guide rails 101 gradually decreases. The symmetrical design can make the movement process of the tray 102 more stable and uniform. At the same time, reference Figure 2 , such a design of the guide rail 101 can enable the tray 102 to extend relative to the connecting end 202 as much as possible, with a larger storage stroke. Preferably, in some embodiments of the present utility model, the starting ends of the guide rails 101 are located on both sides of the tray 102 in the second direction, and the end points of the guide rails 101 are as close as possible to the first reference line 204. In this way, the length of the guide rail 101 in the direction of the second reference line 205 can reach the longest, thereby increasing the maximum stroke that the sliding end 203 can slide, and thus improving the telescopic formation of the tray 102.

[0042] Or, in some other embodiments not shown, the guide rail 101 can also be designed such that the distance between the two guide rails 101 gradually decreases along the second direction. The technical effects that can be achieved by such a design are the same as those of Figure 2 And Figure 4On the contrary, when the pallet 102 is in the storage position, the connecting rod 103 is perpendicular to the rail portion, and the storage stroke is relatively small. When the pallet 102 is in the extended position, the connecting rod 103 and the rail portion form an angle as shown in Figure 2 The included angle shown has a relatively large extension stroke. Specifically, the arrangement of the guide rails 101 can be adjusted according to actual usage requirements.

[0043] Alternatively, referring to Figure 5 , in some other embodiments of the present invention, the two guide rails 101 are arranged straight along the same direction, and the extending direction of the guide rails 101 is perpendicular to the first direction. As shown in Figure 5 , setting the straight guide rails 101 perpendicular to the first direction can make the connecting rod 103 coincide with the guide rails 101 when the pallet 102 is in the middle position. At this time, whether the pallet 102 is pushed inward along the first direction or pulled outward along the second direction, the force can be completely applied in the direction perpendicular to the connecting rod 103, making the pushing and pulling more labor-saving. In addition, referring to Figure 5 , in some embodiments of the present invention, the two guide rails 101 are set as an integral track. Such a design does not conflict with the symmetrical design of this solution, does not affect the rotation of the connecting rod 103, and an integral track is more convenient for processing, and the overall structure is more concise.

[0044] The guide rails 101 are not limited to being straight. In some other embodiments not shown, the guide rails 101 can also be designed as curved segments, as long as the sliding end 203 can slide therein and drive the pallet 102 to move along the first direction.

[0045] It should be noted that referring to Figure 2 , in some embodiments of the present invention, the projection of the connection end 202 along the first direction is located outside the projection of the guide rail 101 along the first direction. In this way, unnecessary interference between the connecting rod 103 and the guide rail 101 during rotation can be reduced, and the moving stroke of the pallet 102 can be effectively increased.

[0046] Referring to Figure 2 , in some embodiments of the present invention, when the pallet 102 is in the storage position, for a connecting rod 103 and a guide rail 101 that are connected to each other, the connecting rod 103 and the guide rail 101 form a first included angle 207. The first included angle 207 faces the first reference line 204, the first included angle 207 is an obtuse angle, and the connecting rod 103 and the first reference line 204 form a second included angle 208, and the second included angle 208 is an acute angle. It should be noted that for the convenience of illustration, in Figure 2The included angle between the connecting rod 103 and the first reference line 204 is not directly marked, but an auxiliary line parallel to the first reference line 204 is drawn. This included angle is the same as the size of the second included angle 208. The first included angle 207 being an obtuse angle indicates that the common projection of the connecting rod 103 and the guide rail 101 on the first reference line 204 is longer. The change in the projection length of the connecting rod 103 on the first reference line 204 and the projection length of the track on the first reference line 204 reflects the stroke size of the pallet 102. The longer the length, the greater the moving stroke. Therefore, such a design enables the pallet 102 to have a larger storage stroke. The second included angle 208 formed by the connecting rod 103 and the first reference line 204 being an acute angle is for the convenience of the connecting rod 103 to smoothly continue sliding within the guide rail 101 when the pallet 102 is pulled in the second direction, to avoid the situation where when the connecting rod 103 is parallel to the first reference line 204, the pulling force in the second direction and the reaction force generated when the connecting rod 103 abuts against the table board 201 completely cancel each other out, resulting in a stuck phenomenon.

[0047] Reference Figure 4 , in some embodiments of the present invention, when the pallet 102 is in the extended position, for a connecting rod 103 and a guide rail 101 that are connected to each other, the connecting rod 103 is perpendicular to the guide rail 101, and the connecting rod 103 forms a third included angle 401 with the first reference line 204. The third included angle 401 is an acute angle. It should be noted that for the convenience of illustration, in Figure 4 the included angle between the connecting rod 103 and the first reference line 204 is not directly marked, but an auxiliary line parallel to the first reference line 204 is drawn. This included angle is the same as the size of the third included angle 401. The connecting rod 103 being perpendicular to the guide rail 101 makes the pallet 102 unable to continue moving in the second direction, achieving a stable effect. The third included angle 401 formed by the connecting rod 103 and the first reference line 204 being an acute angle is also for the connecting rod 103 to smoothly continue sliding within the guide rail 101 when the pallet 102 is pushed in the first direction.

[0048] Reference Figure 5 , in some embodiments of the present invention, the symmetry axis of the two connecting rods 103 is the first reference line 204, and the first reference line 204 extends along the first direction. When the connecting rod 103 is perpendicular to the first reference line 204, the minimum distance between the connecting rod 103 and the first reference line 204 is L1, and the minimum distance between the guide rail 101 and the first reference line 204 is L2, where L1 > L2 ≥ 0. Designing L1 > L2 is to enable the connecting rod 103 to smoothly rotate along the movement trajectory 206 of the sliding end, avoiding the situation where the connecting rod 103 gets stuck at the end of the guide rail 101 and cannot continue to rotate. Making L1 > 0 is to ensure that the two connecting rods 103 do not interfere with each other even when the relative distance is the closest, ensuring that the entire pushing and pulling process proceeds more smoothly.

[0049] In some embodiments of the present utility model, the guide rail 101 can be arranged at one end close to the first side edge 301. At this time, the tray 102 has a larger storage stroke and a smaller extension stroke. On the contrary, the guide rail 101 can also be arranged at one end close to the second side edge 302. At this time, the tray 102 has a smaller storage stroke and a larger extension stroke, and can be specifically adjusted according to actual usage requirements.

[0050] Reference Figure 9 and Figure 10 , in some embodiments of the present utility model, the keyboard tray 100 further includes a first locking member 1001. The guide rail 101 is connected to the sliding end 203 through the first locking member 1001. The guide rail 101 is a hollow structure, and the guide rail 101 is provided with a first guide groove 1002. The sliding end 203 is provided with a through hole 1003. The first locking member 1001 includes a first head 1004, a rod portion 1005, and a second head 1006 that are connected in sequence. The first head 1004 is located inside the hollow structure. After the rod portion 1005 passes through the first guide groove 1002 and the through hole 1003, it is connected to the second head 1006. The first head 1004 and the second head 1006 jointly abut against the first guide groove 1002 and the sliding end 203, and the rod portion 1005 can move along the first guide groove 1002. Such a design enables the sliding end 203 to slide relative to the guide rail 101 and also move relative to the guide rail 101. At the same time, the preferred solution of the first locking member 1001 is a combination of a bolt and a nut. The second head 1006 and the rod portion 1005 are a bolt fixedly connected, and the first head 1004 is the corresponding nut. Such a design is convenient for disassembly and can adjust the tightness or directly tighten it according to usage requirements.

[0051] Reference Figure 1 and Figure 6, in some embodiments of the present utility model, the keyboard tray 100 further includes a table clamp assembly 104. The connecting rod 103 is connected to the tabletop 201 through the table clamp assembly 104. The table clamp assembly 104 includes a first connecting seat 601, a second locking member 606, and a second connecting seat 609. The first connecting seat 601 includes a first connecting piece 602, a second connecting piece 603, and a third connecting piece 604. The top end of the second connecting piece 603 is connected to the first connecting piece 602, and the bottom end of the second connecting piece 603 is connected to the third connecting piece 604. The first connecting piece 602, the second connecting piece 603, and the third connecting piece 604 jointly define a receiving groove 605 for receiving a part of the tabletop 201. The second locking member 606 includes an operating end 607 and an abutting end 608. The second locking member 606 is passed through the third connecting piece 604. The operating end 607 is located outside the receiving groove 605, and the abutting end 608 is located inside the receiving groove 605.

The connecting end 202 of one connecting rod 103 is rotatably connected to the first tabletop 209, and the connecting end 202 of the other connecting rod 103 is rotatably connected to the second tabletop 210. If the tabletop 201 with the fourth included angle 303 is as Figure 7 shown, for the keyboard tray 100 in the prior art, when the tray 102 is in the storage position, there are still many parts located outside the fourth included angle 303, and the storage effect is poor. And as Figure 2 shown, for the keyboard tray 100 of the present utility model, after its two ends are respectively connected to the first tabletop 209 and the second tabletop 210, when in the storage position, most of it is deeper than the tabletop 201, and has a better storage effect. Preferably, as Figure 3 shown, the fourth included angle 303 includes a first edge 304 and a second edge 305 connected to each other. One connecting end 202 is rotatably connected to the first edge 304, and the other connecting end 202 is rotatably connected to the second edge 305. In this way, the rotation range of the connecting rod 103 can be maximally utilized, and the effective stroke of the tray 102 can be improved.

[0055] It should be noted that, in some embodiments of the present utility model, the first tabletop 209 and the second tabletop 210 can be formed with the fourth included angle 303 by splicing, or can be an integral body, and the fourth included angle 303 is obtained by cutting the integral body.
