For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0032] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application.

Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples. In addition, those skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of the different embodiments or examples without contradiction.

[0033] The embodiments of the present application will be described below in conjunction with Figures 1 to 6 The embodiments of the present application are described. It should be understood that the following description is only a schematic embodiment of the present application and does not constitute a limitation on the present application.

[0034] As Figure 1 and Figure 2As shown, the present application provides a bunk lower baffle mechanism 100, comprising: a first baffle 110 and a second baffle 120, the first baffle 110 is provided with a U-shaped gap 111; the second baffle 120 is arranged in the U-shaped gap 111, and one side of the second baffle 120 is rotatably connected with one side of the first baffle 110. That is, the second baffle 120 includes two working states, in the first working state, the second baffle 120 is arranged in the U-shaped gap 111 of the first baffle 110, the front and back of the first baffle 110 and the second baffle 120 are in the same plane, and the size of the second baffle 120 matches the U-shaped gap 111 of the first baffle 110. In the second working state, the second baffle 120 rotates relative to the first baffle 110, and an angle is formed between the first baffle 110 and the second baffle 120. For example, when the seat 300 backrest is reclined, the second baffle 120 is pushed to rotate around the first baffle 110, the seat 300 backrest is attached to the second baffle 120, and the reclining angle of the seat 300 backrest is the rotation angle of the second baffle 120 relative to the first baffle 110.

[0035] Further, the U-shaped gap 111 of the first baffle 110 includes opposite fourth and sixth edges, and a fifth edge connected between the fourth and sixth edges, the second baffle 120 can be rotatably connected with the fifth edge, and the width of the fifth edge is greater than or equal to the width of the seat 300 backrest. The second baffle 120 switches between the first working state and the second working state, thereby adjusting the angle between the second baffle 120 and the first baffle 110, avoiding the seat 300 backrest, increasing the reclining angle of the seat 300 backrest, and thereby improving the comfort of the driver.

[0036] Continuing to refer to Figure 1 In an embodiment of the present application, the bunk lower baffle mechanism 100 further comprises a reset member 102, which is arranged at the rotatable side of the second baffle 120 and the first baffle 110, and is used for resetting after rotation. Specifically, after the second baffle 120 rotates relative to the first baffle 110, i.e. from the second working state to the first working state, the reset member 102 makes the second baffle 120 return from the state with an angle relative to the first baffle 110 to the state in the same plane with the first baffle 110, i.e. from the second working state to the first working state.

[0037] For example, the first baffle 110 and the second baffle 120 are connected through the hinge 101, and the reset member 102 is a spring arranged on the hinge 101. That is, when the second baffle 120 has a certain rotation angle with the first baffle 110, the reset member 102 can be compressed, and under the action of the elastic restoring force of the reset member 102, the second baffle 120 returns to the state of being coplanar with the first baffle 110 in the absence of rotation force of the second baffle 120. Of course, the first baffle 110 and the second baffle 120 can also be connected through a rotating shaft or other rotatable connecting members, and reset through other reset members 102 such as spring sheets.

[0038] With reference to the foregoing Figure 2 In another embodiment of the present application, the bunk lower baffle mechanism 100 further comprises a limiting member 103 arranged on one side of the first baffle 110, and the limiting member 103 is used to limit the rotation angle of the second baffle 120 rotating to the side. That is, only when the second baffle 120 rotates to the limit position, the second baffle 120 will contact the limiting member 103, and the maximum rotation angle of the second baffle 120 is limited. For example, 50 degrees. By arranging the limiting member 103, it is prevented that the driver damages the reset member 102 by misoperation when adjusting the seat back 300, and the plastic part at the connection of the first baffle 110 and the second baffle 120 is prevented from whitening.

[0039] Specifically, the limiting member 103 is arranged on the side of the first baffle 110 away from the seat back 300, and the second baffle 120 rotates around the first baffle 110 to the side away from the seat back 300. In the process of continuous rotation of the second baffle 120, the second baffle 120 eventually abuts against the limiting member 103, at this time, the second baffle 120 reaches the limit position of the rotation angle, i.e., the maximum rotation angle. At the same time, the seat back 300 also reaches the maximum reclining angle. The limiting member 103 can be detachably connected with the first baffle 110, so as to facilitate the adjustment of the position of the limiting member 103 on the first baffle 110, so as to realize the adjustment of the maximum rotation angle of the second baffle 120.

[0040] Further, in the optional embodiment of the present application, the limiting member 103 is L-shaped, one end of the limiting member 103 is connected with the first baffle 110, i.e., one end of the L-shaped is connected with the first baffle 110, and the other end of the limiting member 103 is provided with an inclined surface, i.e., the other end of the L-shaped has an inclined surface, and the inclined surface is used to abut against the second baffle 120. That is, the inclination angle of the inclined surface is the rotation angle of the second baffle 120. The limiting member 103 with the inclined surface better fits the second baffle 120, and has a better supporting and limiting effect on the second baffle 120.

[0041] In order to better achieve the limiting and supporting effect of the limiting piece 103, a plurality of limiting pieces 103 are arranged in the length direction of the fifth edge of the first baffle 110, and the plurality of limiting pieces 103 simultaneously limit and support the second baffle 120.

[0042] In addition, as shown in Figure 1 and Figure 2 In some embodiments of the present application, the bunk lower baffle mechanism 100 further comprises a clamping assembly 104, the clamping assembly 104 comprises a first clamping piece 124 and a second clamping piece 114, the first clamping piece 124 is arranged on the first baffle 110, and the second clamping piece 114 is arranged on the second baffle 120, the first clamping piece 124 and the second clamping piece 114 are used for clamping and cooperating in one rotation direction of the second baffle 120. In other words, the clamping assembly 104 is used to realize the clamping and limiting of the first baffle 110 and the second baffle 120 in one direction. For example, one rotation direction is the direction of rotating and separating of the second baffle 120 away from the seat back around the rotating shaft, that is, rotating clockwise, and then the second baffle 120 is rotated and buckled to the direction of approaching the seat back through the reset piece 102, that is, rotating counterclockwise. That is, the directions of buckling and separating are fixed and cannot be changed.

[0043] Specifically, in the first working state, the first clamping piece 124 and the second clamping piece 114 are buckled to control the surface difference of the first baffle 110 and the second baffle 120, control the gap between the second baffle 120 and the bunk body 200, and avoid the first baffle 110 and the second baffle 120 from shaking and generating abnormal sound during the operation of the working machine. In the second working state, the first clamping piece 124 and the second clamping piece 114 are separated. Among them, the clamping assembly 104 makes the second baffle 120 can only be buckled and separated in one rotation direction relative to the first baffle 110.

[0044] For example, Figure 1 and Figure 2As shown, the first clamping member 124 is a clamping hole formed in the first baffle 110, and the second clamping member 114 is a clamping pin arranged on the second baffle 120. When the second baffle 120 is in the first working state, the clamping pin is clamped in the clamping hole. The opening of the clamping hole is away from the backrest of the seat 300. When the second baffle 120 is in the second working state, the clamping pin is separated from the clamping hole. Of course, the clamping assembly 104 can also use other forms of clamping members. When the seat backrest quickly returns, the second baffle 120 can automatically return and clamp, and the return time is about 0.7s. When the seat is an electric seat and slowly returns, the driver can manually clamp the second baffle 120 to return. The clamping interference of the clamping assembly 104 is 1.8mm, which can effectively prevent shaking and abnormal sound. The clamping assembly 104 realizes the movement of the first baffle 110 and the second baffle 120 in two degrees of freedom.

[0045] In addition, in some embodiments of the present application, the second baffle 120 includes a first edge, a second edge, and a third edge, the first edge and the third edge are arranged on both sides of the second edge, the second edge is rotatably connected with the first baffle 110, and the first edge and / or the third edge is provided with the clamping assembly 104.

[0046] In other words, the first edge of the second baffle 120 corresponds to the fourth edge of the first baffle 110, the second edge of the second baffle 120 corresponds to the fifth edge of the first baffle 110, and the third edge of the second baffle 120 corresponds to the sixth edge of the first baffle 110. The second edge and the fifth edge are rotatably connected, the first edge and / or the third edge is provided with the clamping pin, and the fourth edge and / or the sixth edge is provided with the clamping hole.

[0047] As shown in Figure 3 and Figure 4 The present application also provides a bunk assembly, which includes a bunk body 200 and the bunk lower baffle mechanism 100 of the above-mentioned embodiments. The bunk lower baffle mechanism 100 is arranged below the bunk body 200 and is arranged perpendicularly to the bunk body 200.

[0048] The length of the bunk lower baffle mechanism 100 can be equal to the length of the bunk body 200. The shape of the bunk body 200 can be a regular rectangle or other special-shaped structure based on the space of the cab. In addition, the bunk body 200 can be a foldable or detachable structure, which is convenient for avoiding when adjusting the seat 300 backrest.

[0049] Further, as shown in Figure 4 and Figure 5As shown, in some optional embodiments of the present application, the bunk body 200 comprises a first bunk pad 201 and a second bunk pad 202, the first bunk pad 201 and the second bunk pad 202 are foldably connected; wherein the second baffle 120 is adjacent to and correspondingly arranged with the first bunk pad 201 and the second bunk pad 202.

[0050] For example, when the bunk body 200 is not needed to be used, the second bunk pad 202 can be folded on the first bunk pad 201, so as to avoid the backrest angle adjustment of the seat 300 (which can be the driver's seat 300 or the front passenger seat 300). The second baffle 120 placed under the second bunk pad 202 is in contact with the backrest during the backrest angle adjustment, and the rotation angle of the second baffle 120 increases continuously when the backrest continuously reclines, until the second baffle 120 contacts the limiting piece 103, so as to reach the limit position of the rotation angle, which can also be the maximum angle of the backrest.

[0051] Alternatively, the maximum rotation angle of the second baffle 120 is greater than the maximum angle of the backrest, for example, the vertical state of the seat 300 backrest is 0 degree, when the seat 300 backrest touches the second baffle 120, the angle of the seat 300 backrest is A degree, when the seat 300 backrest is adjusted to the maximum angle, the angle of the seat 300 backrest is B degree, B degree is greater than A degree, at this time, the second baffle 120 can have a spacing between the limiting piece 103. In other words, when the second baffle 120 contacts the limiting piece 103, the angle of the seat 300 backrest is C degree, C degree is greater than B degree, for example, C degree-B degree=10 degrees, B degree-A degree=40 degrees.

[0052] After the driver's rest is over, the backrest is reset through the adjusting device of the seat 300 itself. And the second baffle 120, under the action of the reset piece 102, returns to the original position, that is, the second baffle 120 is coplanar with the first baffle 110, and the clamping assembly 104 completes the clamping fixation.

[0053] Of course, in other embodiments of the present application, the bunk body 200 can also comprise multiple sets of bunk pads, for example, a third bunk pad, the first bunk pad 201, the second bunk pad 202 and the third bunk pad can be folded together, the first bunk pad 201 can correspond to the driver's seat 300, and the third bunk pad can correspond to the front passenger seat 300. When the front passenger seat 300 and the driver's seat 300 are both adjusted in angle, the second baffle 120 under the first bunk pad 201 and the second baffle 120 under the third bunk pad can be adjusted in angle at the same time to achieve avoidance. Wherein the bunk body 200 comprises a foamed layer and a wooden board layer, both the foamed layer and the wooden board layer are foldable structures. That is, the first bunk pad 201, the second bunk pad 202 and the third bunk pad all contain the foamed layer and the wooden board layer.

[0054] Specifically, such as Figure 6 As shown, in some alternative embodiments of the present invention, the first berth 201 and the second berth 202 are connected by a zipper 203. During the folding process of the first berth 201 and the second berth 202, the second berth is rotated 180° around the zipper 203 as the rotation center and folded above the first berth 201.

[0055] This invention also provides a working machine, including a seat 300 and a sleeper assembly as described in the above embodiment, wherein the backrest of the seat 300 is arranged opposite to the second baffle 120. The working machine can be a truck, dump truck, etc. For example, when a dump truck is queuing for loading, the driver may want to rest briefly in the seat, but the seat is restricted by the rear sleeper berth and the lower baffle, preventing the seat back from reclining to a near-flat angle. Currently, the maximum reclining angle of the seats in dump trucks is around 107°. Currently, dump truck models typically increase the seat back angle by reducing the width of the sleeper berth, which affects passenger comfort. This invention, however, increases the maximum reclining angle of the seat through a rotatable second baffle 120, resulting in a simple structure and low modification costs.

[0056] The sleeper berth lower baffle mechanism 100 provided by the present invention has a U-shaped notch 111 on the first baffle 110, and a second baffle 120 is placed in the U-shaped notch 111. The second baffle 120 can rotate relative to one side of the first baffle 110. During the rotation, the second baffle 120 avoids the backward tilt of the seat 300 backrest, thereby increasing the backward tilt angle of the seat 300 backrest and meeting the comfort needs of the driver during short rest. The structure is simple and the cost is low.

[0057] Furthermore, the sleeper assembly and working machinery provided by the present invention also possess the various advantages described above due to the sleeper lower baffle mechanism 100 described above.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
