Description

Technical Field

[0001] The utility model belongs to the field of automobile seats, and in particular relates to a folding table board installed inside a seat armrest. Background Art

[0002] The seat armrests were originally designed to provide elbow support for passengers, and later developed into storage boxes to expand the storage space inside the car. However, with the quickening pace of life, passengers will eat or work, check documents, etc. while driving, so folding tables that can be installed inside the seat armrests came into being.

[0003] Existing folding table boards such as Figure 1 and Figure 2 As shown, the foldable table top 1 includes a front table top assembly 101 and a rear table top assembly 102. The front table top assembly 101 is connected to the rear table top assembly 102 via two first dampers 103. One end of the rear table top assembly 102 is rotatably connected to one end of a cantilever 105 via a second damper 104. The other end of the cantilever 105 is rotatably connected to one end of a connecting arm 106. A support beam 107 that can slide relative to the cantilever 105 is provided between the cantilever 105 and the connecting arm 106. A linear positioning damper 108 is provided at the other end of the connecting arm 106. A first rotating shaft 1081 on the linear positioning damper 108 penetrates into the side walls 1091 on both sides of the mounting arm 109 and is rotatably connected to the mounting arm 109. Finally, the foldable table top is installed inside the seat armrest box via the mounting arm 109. However, the existing foldable table top has the following problems:

[0004] 1. The first damper 103 is as follows Figure 3As shown, it includes two hinge blocks 1031, a hinge sleeve 1032, an inner sleeve 1033, a second rotating shaft 1034 and a first damping plate 1035. The two second rotating shafts 1034 are designed in parallel. A plurality of first damping plates 1035 are mutually attached and tightly hold the second rotating shafts 1034. The inner sleeve 1033 wraps the first damping plates 1035 and directional installs the rocker arms of the first damping plates 1035. The inner sleeve 1033 is sleeved in the hinge sleeve 1032. Both ends of the second rotating shaft 1034 are installed on the hinge blocks 1031, so that the two hinge blocks 1031 are rotatably connected relative to the two second rotating shafts 1034. The two hinge blocks 1031 are fixed between the front table board assembly 101 and the rear table board assembly 102, so that the front table board assembly 101 and the rear table board assembly 102 can be rotatably connected through the second rotating shaft 1034. Since the structure of the existing first damper 103 includes two hinge blocks 1031 and a hinge sleeve 1032 connected between the two hinge blocks 1031 through the second rotating shaft 1034, the thickness of the first damper 103 is relatively thick, so the thickness of the foldable table board 1 is also relatively thick, about 12-14mm, which requires increasing the width of the armrest box, occupying the space in the car.

[0005] 2. Since the foldable table top 1 is relatively thick, in order to better meet the current need for lightweighting, the foldable table top 1 needs to be made into a hollow structure, and skins are installed on both sides of the hollow structure to cover it. Therefore, the process is more complicated and the production cost is increased.

[0006] 3. The structure of the linear positioning damper 108 is as follows Figure 4 As shown, it includes a first rotating shaft 1081, a plurality of second damping plates 1082 and two mounting plates 1083. The plurality of second damping plates 1082 fit closely with each other and hold the first rotating shaft 1081 tightly. Two mounting plates 1083 are provided on the first rotating shaft 1081 on both sides of the plurality of second damping plates 1082. The linear positioning damper 108 is connected to the connecting arm 106 through the mounting plates 1083, and is connected between the two side walls 1091 of the mounting arm 109 through the roller columns at both ends of the first rotating shaft 1081 (see Figure 2 ), so when the linear positioning damper 108 needs to be replaced, the connecting arm 106, the linear positioning damper 108 and the mounting arm 109 need to be replaced together, which is more costly.

[0007] 4. Since the mounting arm 109 needs to be connected to the rolling posts at both ends of the first rotating shaft 1081, side walls 1091 need to be provided on both sides of the mounting arm 109. Therefore, when the folding seat plate is installed in the armrest box, the volume of the armrest box needs to be further increased, making the space in the car more crowded.

[0008] 5. The linear positioning damper 108 is formed by a plurality of second damping plates 1082 that adhere to each other and hold the first rotating shaft 1081, so that the connecting arm 106 is subjected to bidirectional force when rotating relative to the mounting arm 109, that is, the damping generated by the linear positioning damper 108 needs to be overcome both when lifting the table top and when putting it down, which makes it more laborious to lift the table top. Utility Model Content

[0009] The purpose of the utility model is to solve the above-mentioned problem and to provide a folding table top installed inside the armrest of a seat. The folding table top is lighter and thinner when foldable, and damping is only generated when the table top is lowered, which can prevent the application from automatically sliding down under the action of gravity. The process is simpler, the cost is lower, and the volume of the armrest box required is smaller.

[0010] In order to achieve the above-mentioned purpose, the utility model provides a foldable table panel installed inside a seat armrest, including a foldable table panel assembly, the foldable table panel assembly including a front table panel assembly, a rear table panel assembly and a dual-axis damping hinge, the opposite sides of the front table panel assembly are rotatably connected to the opposite sides of the rear table panel assembly through a dual-axis damping hinge, the foldable table panel assembly is arranged on one side of an upper connecting arm, the end of the upper connecting arm facing away from the side of the foldable table panel assembly is rotatably connected to one end of the connecting arm, a support beam that can support the upper connecting arm is slidably connected between the upper connecting arm and the connecting arm, and the other end of the connecting arm is rotatably connected to a side wall of one side of the mounting arm through a one-way rotation damper.

[0011] Advantages and beneficial effects of the utility model

[0012] 1. The utility model uses a double-axis damping hinge for rotational connection between the front table board assembly and the rear table board assembly, so that the thickness of the foldable table board assembly after unfolding can reach 7-8mm, which is more in line with the current demand for lightweight and reduces the volume of the armrest box.

[0013] 2. The foldable table top assembly of the utility model is thinner and lighter, so it does not need to be made into a hollow structure, nor does it need to be provided with skins on both sides, so the process is simpler and the production cost is lower.

[0014] 3. The utility model installs a one-way rotation damper between the connecting arm and the mounting arm. The damper body of the one-way rotation damper is connected to the side wall of the mounting arm by bolts, and the damper shaft is connected to the connecting arm by bolts. Therefore, when replacement is required, only the one-way rotation damper needs to be replaced separately, which is lower in cost.

[0015] 4. The one-way rotation damper in the utility model only needs to be connected to one side wall of the mounting arm, so the volume of the armrest box can be further reduced.

[0016] 5. The utility model uses a one-way rotating damper between the connecting arm and the mounting arm, so when lifting the table top, it is easy to lift it up without overcoming the damping. When lowering the table top, it is necessary to overcome the damping generated by the one-way rotating damper to prevent the application from automatically sliding down under the action of gravity.

[0032] like Figure 5-Figure 7As shown, a foldable table installed inside a seat armrest includes a foldable table assembly 1, wherein the foldable table assembly 1 includes a front table assembly 101, a rear table assembly 102 and a biaxial damping hinge 103, wherein opposite sides of the front table assembly 101 are rotatably connected to opposite sides of the rear table assembly 102 via the biaxial damping hinge 103, wherein the front table assembly 101 includes a front table cover, a front table skin and a front table metal plate, wherein the front table cover is connected to the front table skin and then connected to the front table metal plate, wherein the rear table assembly 102 includes a rear table cover, a rear table skin and a rear table metal plate, wherein the rear table cover is connected to the rear table skin and then connected to the rear table metal plate; the structure of the biaxial damping hinge 103 is shown in FIG. Fig. 9 , including a shell 131, the shell 131 has two inner chambers 1311, and two third rotating shafts 132 designed in parallel are rotatably connected in the two inner chambers 1311. The third rotating shaft 132 is divided into a fixed end 1322 and a connecting end 1323 by a clamping table 1321. The third rotating shaft 132 cooperates with the shell cover 133 through the clamping table 1321 to set the fixed end 1322 in the inner chamber 1311. The shell cover 133 is connected to the shell 131 by screws. A plurality of third damping plates 134 that fit each other are tightly embraced on the fixed end 1322, and the rocker arm of the third damping plate 134 is directional installed through the inner chamber 1311. The connecting end 1323 of the third rotating shaft 132 passes through the shell cover 133, and has planes 13231 on the opposite sides of the connecting end 1323. When the front table assembly 101 and the rear table assembly 102 When the connection is rotated by the dual-axis damping hinge 103, the two third rotating shafts on the dual-axis damping hinge 1033 need to be respectively inserted into the connecting holes on one side of the front table board assembly 101 and the rear table board assembly 102, and screws are provided in the threaded holes perpendicular to the connecting holes. Since the opposite sides of the connecting end 1323 of the third rotating shaft have flat surfaces 13231, the third rotating shaft 132 of the dual-axis damping hinge 103 can be fixed relative to the front table board assembly 101 and the rear table board assembly 102 by pressing the screws on the flat surfaces 13231. The dual-axis damping hinge 3 is only 7-8mm thick, which is in line with the concept of the thin plate of the present application. The thickness of the foldable table board assembly 1 after unfolding in the present application is the same as the thickness of the dual-axis damping hinge 3. Therefore, it does not need to be made into a hollow structure, nor does it need to be covered with skin on both sides. The process is simpler, the production cost is lower, and the armrest box used to install the present application is smaller.

[0033] like Figure 8As shown, the foldable table board assembly 1 is connected to one side of the upper connecting arm 2 by screws, and is sealed by a blocking cover 10 after connection. A drawstring 9 is provided between the foldable table board assembly 1 and the upper connecting arm 2, and the drawstring 9 is convenient for pulling the present application out of the armrest box. The end of the upper connecting arm 2 away from the side of the foldable table board assembly 1 is rotatably connected to one end of the connecting arm 3. Specifically, a third damper is pressed on the two side walls of the connecting arm 3, and the fifth rotating shaft passes through the upper connecting arm 2 and the third damper to make the upper connecting arm 2 rotatably connected to the connecting arm 3, and is sealed by a blocking cover 10 after connection. The side of the upper connecting arm 2 away from the foldable table board assembly 1 is connected to the slide frame 7 by four screws, and two rubber blocks 8 are provided at the right end of the slide frame 7. The rubber block 8 can prevent the support beam 4 from sliding to the right end of the slide frame 7 and generating abnormal noise. 4 is slidably connected, and the other end of the support beam 4 is rotatably connected to the storage cavity 31 of the connecting arm 3 through a pin shaft. Specifically, two first side sleeves are provided in the slideways on both sides of the slide groove frame 7, and an intermediate sleeve is provided in the middle of the sliding end of the support beam 4. The intermediate sleeve can prevent grease on the fourth rotating shaft from leaking out. The fourth rotating shaft passes through the sliding end and the intermediate sleeve and is connected to the first side sleeve in the slideway. Second side sleeves 11 are provided on the opposite side walls of the storage cavity 31 of the connecting arm 3, and the pin shaft passes through the rotating end of the support beam 4 and the second side sleeve 11 to rotatably connect the rotating end of the support beam 4 with the storage cavity 31. The first side sleeve and the second side sleeve can prevent abnormal noise from occurring when the support beam 4 and the connecting arm 3 rotate and slide, and are sealed by a blocking cover 10 after connection. The left end of the connecting arm 3 is rotatably connected to a side wall 51 of the mounting arm 5 through a one-way rotation damper 6.

[0034] As a further optimization, Fig.10 As shown, the one-way rotating damper 6 includes a damper body 61 and a damper shaft 62, the damper body 61 is connected to a side wall 51 of a mounting arm 5 by screws, one end of the damper shaft 62 is rotatably connected to the damper body 61, and the other end of the damper shaft 62 passes through the mounting hole 32 on the connecting arm 3 and is connected to the connecting arm 3 by bolts. The one-way rotating damper 6 is an existing structure with a model of JT-100. The present application is connected to a metal frame on one side of the armrest box through a mounting arm 5.

[0035] Compared with the existing structure, the present invention reduces one side wall of the mounting arm by connecting the linear positioning damper 108 with the two side walls 1091 of the mounting arm 109, making the mounting arm smaller in size. At the same time, the one-way rotation damper 6 in the present invention is subjected to one-way force, and is only subjected to force when the table top is closed, so as to prevent the present invention from sliding freely under the influence of gravity. Fig.10It can be seen from the figure that the one-way rotation damper 6 is connected between the side wall 51 of the mounting arm 5 and the connecting arm 3 by screws, so when the one-way rotation damper 6 needs to be replaced, it only needs to be replaced separately.
