Detailed Implementation

[0031] In the existing technology, the right armrest can only adjust the position of the elbow support forward and backward and the angle of the elbow support up and down, but cannot adjust the position of the elbow support left and right, which cannot meet the needs of drivers of different heights and body types.

[0032] To overcome the shortcomings of the prior art, this application provides an elbow support assembly. Since the first end of the connecting section can slide vertically and swing up and down on the support frame, the first end of the rotating section is connected to the second end of the connecting section in a way that allows left and right rotation. Multiple rotating sections are connected end to end in a way that allows left and right rotation. The elbow support is slidably connected to the last rotating section along the extension direction of the last rotating section. In this way, the height, pitch angle, front and rear position, and left and right position of the elbow support can be adjusted simultaneously. The driver can adjust the elbow support according to his own height and body shape to obtain a better support arm effect.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] This application provides an elbow support assembly that can be installed in a driver's cab to support the driver's arm. Further, the driver's cab is equipped with a seat (driver's seat), and the elbow support assembly can be installed on the right side of the seat to support the driver's right arm.

[0035] See Figure 1 and Figure 2 In some embodiments, the elbow support assembly includes a support frame 100, a connecting arm 200, and an elbow support 300. The connecting arm 200 includes a connecting section 210 and multiple rotating sections. The first end of the connecting section 210 is vertically slidable and vertically swingable, and is disposed on the support frame 100. The first rotating section is rotatably connected to the second end of the connecting section 210. The multiple rotating sections are rotatably connected end-to-end. The elbow support 300 is slidably connected to the last rotating section along the extending direction of the last rotating section.

[0036] The support frame 100 can be long and narrow, and can be erected on the right side of the seat to support the connecting arm 200 and the elbow rest 300 thereon.

[0037] The connecting arm 200 includes a connecting section 210 and multiple rotating sections. The connecting section 210 and multiple rotating sections can be arranged in the same plane. When the plane where the connecting arm 200 is located is horizontal, the connecting arm 200 extends as a whole in the front-back direction.

[0038] In this embodiment, since the first end of the connecting segment 210 can slide vertically and swing up and down on the support frame 100, multiple rotating segments can rotate left and right and are connected end to end in sequence, and the elbow support 300 is slidably connected to the rotating segment at the end along the extension direction of the rotating segment at the end.

[0039] When the first end of the connecting section 210 slides up and down along the support frame 100, the connecting section 210 can drive multiple rotating sections to move up and down as a whole. The elbow support 300 is set at the end of the rotating section, so the elbow support 300 can also move up and down. That is, the height of the elbow support 300 is adjusted by the connecting section 210 sliding up and down along the support frame 100.

[0040] When the first end of the connecting section 210 swings up and down around that end, the plane where the connecting arm 200 is located also swings up and down. The elbow support 300 is located at the rotating section at the end, so the elbow support 300 can also swing up and down. That is, by swinging the connecting section 210 up and down, the pitch angle of the elbow support 300 can be adjusted.

[0041] The elbow support 300 is slidably connected to the rotating section at the end along the extension direction of the rotating section. The connecting arm 200 extends generally in the front-back direction, so when the elbow support 300 is still sliding along the extension direction of the rotating section, the position of the elbow support 300 in the front-back direction can be adjusted.

[0042] Furthermore, since the first rotating segment is rotatably connected to the second end of the connecting segment 210, and multiple rotating segments are connected end-to-end in a rotatable manner, the rotating segments and the multiple connecting segments 210 can swing left and right within the plane of the connecting arm 200. For example, when the last rotating segment swings to the left, it can directly drive the elbow support 300 to move to the left, i.e., towards the driver; when the last rotating segment swings to the right, it can move away from the driver.

[0043] Therefore, in the elbow support assembly of this application, since the first end of the connecting section 210 can slide vertically and swing up and down on the support frame 100, the first end of the rotating section can rotate left and right and is connected to the second end of the connecting section 210, and multiple rotating sections can rotate left and right and are connected end to end in sequence, and the elbow support 300 is slidably connected to the last rotating section along the extension direction of the last rotating section, the height, pitch angle, front and back position, and left and right position of the elbow support 300 can be adjusted. The driver can adjust the elbow support 300 according to his own height and body shape to obtain a better arm support effect.

[0044] See Figures 1 to 3 In some embodiments, the connecting arm 200 includes two rotating segments, namely a first rotating segment 220 and a second rotating segment 230. A first end of the first rotating segment 220 is rotatably connected to a second end of the connecting segment 210, and a second end of the first rotating segment 220 is rotatably connected to a first end of the second rotating segment 230. An elbow support 300 is slidably connected to the second rotating segment 230 along its extending direction.

[0045] In other words, the connecting arm 200 is a three-segment joint (one connecting segment 210 and two rotating segments). The dual rotating segment design (first rotating segment 220 and second rotating segment 230) forms a joint-like linkage mechanism, achieving multi-angle spatial coverage and better adjustment effect.

[0046] Furthermore, compared to a single-segment rotating arm, the combination of two angle segments expands the working range and enhances the adaptability of the connecting arm 200 to complex environments (such as obstacle avoidance). For example, when the elbow support assembly can be installed on the right side of the seat of a vehicle or construction machinery, interference between the elbow support 300 and the operating lever can be relatively easily avoided, facilitating user adjustment.

[0047] In some embodiments, the elbow support 300 includes a mounting portion 310 and a lifting portion 320. The lifting portion 320 is fixed to the mounting portion 310 and is used to support the arm. The mounting portion 310 is provided with a first sliding groove 312. The elbow support assembly also includes a sliding frame 400, which includes a mounting section 410 and a sliding section 420. The mounting section 410 is fixed to a second rotating section 230, and the sliding section 420 extends into the first sliding groove 312 to be slidably connected with the first sliding groove 312.

[0048] In this embodiment, the support part 320 can be disposed above the mounting part 310, and the upper surface of the support part 320 can serve as a support wall 322 for supporting the user's arm. The mounting part 310 and the support part 320 can be integrally formed or assembled. During assembly, fasteners can be used to fix the two together.

[0049] The mounting part 310 is provided with a first slide groove 312. The first slide groove 312 can extend along the extension direction of the rotating section. The first slide groove 312 is open to one or both sides of the lateral side of the mounting part 310.

[0050] The mounting section 410 of the sliding frame 400 can be fixed to the side of the rotating section by fasteners. The sliding section 420 of the sliding frame 400 can be formed on the upper edge of the mounting section 410 and bends and extends to one side of the mounting part 310 so as to pass through the first groove 312 on the mounting part 310.

[0051] When the elbow support 300 slides along the extension direction of the rotating section, the sliding section 420 can act as a constraint on the elbow support 300 so that the sliding direction of the elbow support 300 does not deviate from the extension direction of the rotating section, thereby ensuring that the elbow support 300 does not deviate from the front-back direction when adjusting its front-back position.

[0052] See Figure 3 Furthermore, the sliding frame 400 also includes a plurality of pulleys 430, which are disposed in the sliding section 420 and slide in cooperation with the first sliding groove 312.

[0053] Specifically, the multiple pulleys 430 can be divided into two groups. One group is set on the upper surface of the sliding section 420 and slides in cooperation with the upper wall of the first sliding groove 312. The other group is set on the lower surface of the sliding section 420 and slides in cooperation with the lower wall of the first sliding groove 312. This can reduce the friction between the sliding section 420 and the first sliding groove 312, making it smoother when adjusting the elbow support 300 in the front and back positions.

[0054] Furthermore, the upper and lower walls of the first slide groove 312 may be respectively provided with slide rails extending along the extension direction of the rotating section. The slide rails slide in cooperation with the pulley 430 to further constrain the trajectory of the elbow support 300 when it slides along the extension direction of the rotating section.

[0055] See Figures 1 to 3 In some embodiments, the support portion 320 has a support wall 322, the middle portion of which is recessed downward relative to the sides in the lateral direction of the support portion 320. This recessed structure in the middle can better wrap around the driver's arm and reduce operating fatigue.

[0056] See Figure 1 and Figure 4 In some embodiments, the surface of the support frame 100 is provided with a vertically extending second slide groove 110, and a slider 130 is disposed in the second slide groove 110. A stop portion 120 is provided at the opening of the second slide groove 110 to stop the slider 130. A connecting portion 212 is provided at the first end of the connecting section 210, and the connecting portion 212 is rotatably connected to the slider 130.

[0057] In this embodiment, the surface of the support frame 100 is provided with a vertically extending second slide groove 110, and the slider 130 is disposed in the second slide groove 110. The slider can slide vertically along the second slide groove 110. Since the connecting part 212 is connected to the slider 130, the connecting part 212 can drive the connecting section 210 to slide up and down. The connecting section 210 can drive multiple rotating sections to move up and down as a whole. The rotating sections can drive the elbow support 300 to move up and down, thus realizing the function of adjusting the height of the elbow support 300.

[0058] Since the connecting part 212 is rotatably connected to the slider 130, the connecting part 212 can drive the connecting section 210 to swing up and down. The connecting section 210 can drive multiple rotating sections to swing up and down as a whole. The rotating sections can drive the elbow support 300 to swing up and down, thus realizing the function of adjusting the pitch angle of the elbow support 300.

[0059] See Figure 1 and Figure 4 In some embodiments, the connecting part 212 is configured as a screw, and the connecting part 212 is screwed into the slider 130, which can fix the slider 130 and the connecting part 210 to the stop part 120.

[0060] Specifically, the connecting part 212 passes through the first end of the connecting section 210 and is inserted into the second slide groove 110, and then connects with the slider 130 in the second slide groove 110.

[0061] When it is necessary to adjust the height and pitch angle of the connecting section 210, the slider 130 and the stop 120, as well as the connecting section 210 and the stop 120, are released so that the slider 130 can slide in the second slide groove 110 and the connecting section 210 can swing up and down around the connecting part 212.

[0062] After adjustment, the slider 130 is screwed in through the connecting part 212, causing it to move towards the inner wall of the stop part 120, and finally fixing the slider 130 to the inner wall of the stop part 120. This locks the height of the slider 130, which in turn locks the height of the elbow support 300.

[0063] At the same time, as the connecting part 212 is screwed in, the connecting section 210 moves toward the outer wall of the stop part 120, and finally fixes the connecting section 210 to the outer wall of the stop part 120. This locks the pitch angle of the connecting section 210, which in turn locks the pitch angle of the elbow support 300.

[0064] See Figure 1 and Figure 4 In some embodiments, the elbow support assembly may also include an operation part 500, which is disposed at one end of the connecting part 212 away from the slider 130, for the user to operate the connecting part 212.

[0065] The operating part 500 is fixed to one end of the connecting part 212 away from the slider 130, providing a larger operating area and making it easier for the user to apply force to the connecting part 212. In some specific embodiments, the operating part 500 can be a cloverleaf handle.

[0066] In some embodiments, the support frame 100 is disposed on one side of the seat, and the second slide 110 is disposed on the side of the support frame 100 opposite to the seat.

[0067] In this way, components such as the connecting arm 200 and the operating part 500 are also positioned on the side of the support frame 100 away from the seat, so that these parts are not easily touched by the driver on the seat, thus improving the reliability of the elbow support assembly.

[0068] This application also provides a construction machine having a cab with a seat. An elbow support assembly is provided on one side of the seat to support the user's arm using an elbow support 300.

[0069] Furthermore, the elbow support assembly can be located on the right side of the driver's seat to support the driver's arm using the elbow support 300.

[0070] In the engineering machinery of this application, since the first end of the connecting section 210 can slide vertically and swing up and down on the support frame 100, the first end of the rotating section can rotate left and right and is connected to the second end of the connecting section 210. Multiple rotating sections can rotate left and right and are connected end to end in sequence. The elbow support 300 is slidably connected to the last rotating section along the extension direction of the last rotating section. In this way, the height, pitch angle, front and rear position, and left and right position of the elbow support 300 can be adjusted at the same time. The driver can adjust the elbow support 300 according to his own height and body shape to obtain a better arm support effect.
