Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an armrest box seat connection structure and agricultural machinery. Background Technology
[0002] In the cab of agricultural machinery (such as harvesters, combine harvesters, etc.), the seat is equipped with an armrest box via an armrest box bracket. With the driver sitting in the seat as a reference, the armrest box is usually located on the right side of the seat. A small number of armrest boxes are modified to be located on the left side of the seat to meet the needs of users whose left hand is dominant.
[0003] Currently, there are two ways in which the armrest box and the seat can be connected. One method is that neither the seat nor the armrest box rotates. This fixed installation method makes it inconvenient for the driver to sit or get out of the seat. The other method is that a rotating disc is fixed to the lower part of the seat frame and is mounted on the base. The seat can rotate 20° to the left or right, and the armrest box can rotate with the seat. This method allows the seat to rotate to the left a certain angle when the driver gets in or out of the car, making it easier to get in and out. However, taking the armrest box as an example where it is located on the right side of the seat, the armrest box rotates to the left in sync with the seat, which will encroach on some of the space between the seat and the steering assembly, potentially causing a collision. The seat rotation is also restricted, making it inconvenient for the driver to get in and out of the car, thus limiting the user experience. Utility Model Content
[0004] This utility model provides a center console seat connection structure and agricultural machinery, which can improve the problem in the prior art where the center console may collide with the steering assembly when the driver gets on and off the vehicle, thus restricting the seat rotation, making it inconvenient for the driver to get on and off the vehicle, and limiting the user experience.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0006] This utility model provides an armrest box seat connection structure, including a base, a rotating disk rotatably connected to the base, a seat bracket fixedly connected to the rotating disk, and an armrest box bracket located on the left or right side of the seat bracket. The upper end of the armrest box bracket is rotatably connected to the seat bracket, and the lower end of the armrest box bracket is detachably connected to a limiting shaft. The base is fixedly connected to a limiting plate, the limiting plate has a limiting groove, and the limiting shaft is slidably connected to the limiting groove.
[0007] The beneficial effects of this utility model are: when the seat, seat bracket and rotating disc rotate toward the side away from the armrest box bracket, the armrest box and armrest box bracket rotate relative to the seat bracket. At the same time, the limiting groove guides the limiting shaft, so that the armrest box and armrest box bracket will not rotate in the same direction as the seat, which makes it easier for the driver to get in and out of the vehicle and ensures the user experience.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, the limiting groove includes two guide grooves and a positioning groove whose two ends are respectively connected to the two guide grooves. The positioning groove and the two guide grooves are both arc-shaped grooves, and the bending direction of the positioning groove is opposite to the bending direction of the two guide grooves.
[0010] Furthermore, the limiting plate includes a support plate fixedly connected to the base at one end, a transition plate fixedly connected to the other end of the support plate at the lower end, and a guide plate fixedly connected to the upper end of the transition plate at one end. The guide plate is supported on the lower side of the armrest box bracket, and the limiting groove is formed through the guide plate.
[0011] Furthermore, a clearance channel is formed between the support plate and the guide plate, and the clearance channel opens toward the rotating disk.
[0012] Furthermore, the limiting shaft includes a bolt, a sleeve rotatably connected to the bolt, and a nut threadedly connected to the bolt. The bolt passes through both the armrest box bracket and the limiting plate, and the side wall of the sleeve abuts against the groove wall of the limiting groove.
[0013] Furthermore, the limiting shaft also includes a washer that rotates on the bolt. The washer is fixedly connected to the sleeve, and the upper and lower sides of the washer abut against the armrest box bracket and the limiting plate, respectively.
[0014] Furthermore, it also includes a vertically arranged rotating shaft, the upper end of which is rotatably connected to the seat bracket, and the lower end of which is rotatably connected to the armrest box bracket.
[0015] Furthermore, the rotating shaft includes a screw rotatably connected to the seat bracket and a shaft threaded to the screw at its upper end, and the armrest box bracket is rotatably connected to the shaft.
[0016] Furthermore, the seat bracket is detachably connected to an ear plate, and the screw is rotatably connected to the ear plate.
[0017] This utility model also provides an agricultural machine, including the aforementioned armrest box and seat connection structure. Attached Figure Description

Detailed Implementation
[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0029] This utility model provides a connection structure for an armrest box and a seat, as described below.
[0030] Example 1
[0031] like Figures 1-8 An armrest box seat connection structure includes a base 1, a rotating disk 11 rotatably connected to the base 1, a seat bracket 2 fixedly connected to the rotating disk 11, and an armrest box bracket 3 located on the left or right side of the seat bracket 2. The upper end of the armrest box bracket 3 is rotatably connected to the seat bracket 2, and the lower end of the armrest box bracket 3 is detachably connected to a limiting shaft 4. The base 1 is fixedly connected to a limiting plate 5, and the limiting plate 5 has a limiting groove 531. The limiting shaft 4 is slidably connected to the limiting groove 531.
[0032] The beneficial effects of this embodiment are: when the seat, seat bracket 2, and rotating disk 11 rotate toward the side away from the armrest box bracket 3, the armrest box and armrest box bracket 3 rotate relative to the seat bracket 2. At the same time, the limiting groove 531 guides the limiting shaft 4, so that the armrest box and armrest box bracket 3 will not rotate in the same direction as the seat. This improves the problem in the prior art where the armrest box may collide with the steering assembly when the driver gets in and out of the vehicle, which restricts the rotation of the seat, making it inconvenient for the driver to get in and out of the vehicle and limiting the user experience.
[0033] Of course, when the seat, seat bracket 2 and rotating disc 11 rotate toward the side near the armrest box bracket 3, the rotating seat bracket 2 can apply a collision force to the armrest box and armrest box bracket 3, causing the armrest box and armrest box bracket 3 to rotate in the same direction. At this time, the limiting shaft 4 can slide adaptively in the limiting groove 531.
[0034] During rotation, the limiting plate 5 is always connected to the armrest box bracket 3 through the limiting shaft 4, forming a stable support for the armrest box bracket 3, ensuring that the armrest box and armrest box bracket 3 remain stably installed under the support of the limiting plate 5 and the seat bracket 2.
[0035] In the diagram, with the driver seated as a reference, the armrest box bracket 3 is installed on the right side of the seat bracket 2. This installation method is suitable for right-handed users. When getting in and out of the vehicle, the seat rotates to the left, and the armrest box and armrest box bracket 3 rotate relative to the seat bracket 2, maintaining their original side positions. When the seat rotates to the right, the armrest box and armrest box bracket 3 rotate accordingly. Alternatively, with the driver seated as a reference, the armrest box bracket 3 can also be installed on the left side of the seat bracket 2. This installation method is suitable for left-handed users.
[0036] Example 2
[0037] like Figures 2-8 Based on embodiment 1, the limiting groove 531 includes two guide grooves 5311 and a positioning groove 5312 that connects the two guide grooves 5311 at both ends. The positioning groove 5312 and the two guide grooves 5311 are both arc-shaped grooves, and the bending direction of the positioning groove 5312 is opposite to the bending direction of the two guide grooves 5311.
[0038] The beneficial effect of adopting the preferred solution in the above embodiments is that the positioning groove 5312 is located in the middle of the two guide grooves 5311. When the seat does not need to rotate, the positioning groove 5312 can limit the limiting shaft 4, thereby indirectly positioning the armrest box bracket 3 and the armrest box, preventing the armrest box from rotating relative to the seat during vehicle operation. When the seat rotates, the limiting shaft 4 can slide from the positioning groove 5312 into the corresponding guide groove 5311, so that the armrest box does not rotate relative to the seat, or the armrest box rotates relative to the seat.
[0039] Example 3
[0040] like Figure 1 and Figure 2 Based on embodiments 1 and 2, the limiting plate 5 includes a support plate 51 fixedly connected to the base 1 at one end, a transition plate 52 fixedly connected to the other end of the support plate 51 at the lower end, and a guide plate 53 fixedly connected to the upper end of the transition plate 52 at one end. The guide plate 53 is supported on the lower side of the armrest box bracket 3, and the limiting groove 531 is opened through the guide plate 53.
[0041] The beneficial effect of adopting the preferred solution in the above embodiments is that during the rotation process, the guide plate 53 is always connected to the armrest box bracket 3 through the limiting shaft 4, forming a stable support for the armrest box bracket 3, ensuring that the armrest box and the armrest box bracket 3 remain stably installed under the support of the guide plate 53 and the seat bracket 2.
[0042] Example 4
[0043] like Figure 1 and Figure 2 Based on embodiments 1-3, a clearance channel 54 is formed between the support plate 51 and the guide plate 53, and the clearance channel 54 opens toward the rotating disk 11.
[0044] The advantage of adopting the preferred solution in the above embodiments is that the rotation space of the rotating disk 11 is formed by the avoidance channel 54, which ensures the smooth rotation of the seat.
[0045] Example 5
[0046] like Figures 5-7 Based on embodiments 1-4, the limiting shaft 4 includes a bolt 41, a sleeve 42 rotatably connected to the bolt 41, and a nut 43 threadedly connected to the bolt 41. The bolt 41 passes through both the armrest box bracket 3 and the limiting plate 5, and the side wall of the sleeve 42 abuts against the groove wall of the limiting groove 531.
[0047] The beneficial effect of adopting the preferred solution in the above embodiments is that when the armrest box and armrest box bracket 3 rotate relative to the seat bracket 2, the sleeve 42 slides in the limiting groove 531 and can rotate adaptively under the action of friction, so as to ensure the smooth relative movement of the limiting shaft 4 and the limiting plate 5 and reduce the noise caused by friction.
[0048] Example 6
[0049] like Figures 5-7 Based on embodiments 1-5, the limiting shaft 4 also includes a pad 44 that rotates on the bolt 41. The pad 44 is fixedly connected to the sleeve 42, and the upper and lower sides of the pad 44 abut against the armrest box bracket 3 and the limiting plate 5, respectively.
[0050] The beneficial effect of adopting the preferred solution in the above embodiments is that the pad 44 forms a partition between the armrest box support 3 and the limiting plate 5 to achieve stable support for the armrest box support 3. Moreover, the pad 44 can move synchronously with the sleeve 42 under the action of friction. Compared with the direct contact between the armrest box support 3 and the limiting plate 5, the friction noise generated when the armrest box support 3 and the limiting plate 5 move relative to each other can be reduced.
[0051] Both the sleeve 42 and the pad 44 can be made of rubber.
[0052] Example 7
[0053] like Figure 1 , Figure 2 , Figure 5 as well as Figure 6 Based on embodiments 1-6, the armrest box seat connection structure of this utility model further includes a vertically arranged rotating shaft 6, the upper end of which is rotatably connected to the seat bracket 2, and the lower end of which is rotatably connected to the armrest box bracket 3.
[0054] The advantage of adopting the preferred solution in the above embodiments is that the rotational connection between the armrest box bracket 3 and the seat bracket 2 is realized through the rotating shaft 6, and the rotational stability is guaranteed.
[0055] Example 8
[0056] like Figure 5 and Figure 6 Based on embodiments 1-7, the rotating shaft 6 includes a screw 61 rotatably connected to the seat bracket 2 and a shaft 62 with its upper end threadedly connected to the screw 61, and the armrest box bracket 3 is rotatably connected to the shaft 62.
[0057] The advantage of the preferred embodiment described above is that the shaft 62 is stably installed using the screw 61, and the armrest box bracket 3 is rotatably connected via the shaft 62. When the armrest box bracket 3 and the seat bracket 2 rotate relative to each other, the screw 61 can rotate relative to the seat bracket 2 under the action of friction.
[0058] Example 9
[0059] like Figure 1 and Figure 2 Based on embodiments 1-8, the seat bracket 2 is detachably connected to the ear plate 21, and the screw 61 is rotatably connected to the ear plate 21.
[0060] The advantage of adopting the preferred solution in the above embodiments is that the connection between the seat bracket 2 and the armrest box bracket 3 is achieved through the ear plate 21.
[0061] The ear plate 21 is L-shaped, with one end extending vertically and detachably connected to the seat bracket 2, and the other end extending horizontally to the upper side of the armrest box bracket 3, and having a through hole for the screw 61 to pass through and rotate for installation.
