[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings; many specific details are set forth in the following description in order to provide a full understanding of this utility model; based on the embodiments of this utility model, those skilled in the art can make similar improvements without departing from the spirit of this utility model, but cannot make all other embodiments obtained without creative effort, therefore this utility model is not limited to the specific embodiments disclosed below.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can also refer to a "transmission connection," that is, a power connection through various suitable methods such as belt drive, gear drive, or sprocket drive. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] In the prior art, the electric transmission vehicle uses a sprocket drive mechanism to drive the traveling wheels, and a guide wheel is set in the sprocket drive mechanism to guide the chain, so as to improve the working stability of the sprocket drive mechanism.

[0038] However, the two guide wheels of the sprocket transmission mechanism need to be fixed separately. In actual operation, the guide wheels are prone to skew due to external forces or installation errors, which can cause the chain and guide wheels to be too tightly fitted or to separate, making it impossible for the guide wheels to accurately guide the chain movement, thus resulting in poor stability of the sprocket transmission mechanism.

[0039] Please see Figures 1 to 7 To address the problem of poor stability in sprocket transmission mechanisms caused by the guide wheel's inability to accurately guide chain movement, this invention provides a sprocket transmission mechanism 10. The sprocket transmission mechanism 10 includes a driving wheel 11, a driven wheel 12, a transmission chain 13, and a guide wheel mounting bracket 14. The driven wheel 12 is positioned opposite to the driving wheel 11. The transmission chain 13 is sleeved on the driving wheel 11 and the driven wheel 12, and is meshed with both the driving wheel 11 and the driven wheel 12. Two guide wheels 146 are movably mounted on the guide wheel mounting bracket 14, and the transmission chain 13 is meshed with both guide wheels 146. This sprocket transmission mechanism 10, by providing a guide wheel mounting bracket 14 and movably mounting the guide wheels 146 on it, allows the guide wheels 146 to adjust their position according to the tension applied by the transmission chain 13, effectively ensuring the stable engagement between the transmission chain 13 and the guide wheels 146, thereby improving the operational stability of the sprocket transmission mechanism 10.

[0040] Specifically, the guide wheel 146 is used to limit the transmission chain 13 in the sprocket transmission mechanism 10, such as restricting the transmission chain 13 to run on a preset path, so as to ensure the stable operation of the transmission chain 13.

[0041] When the connection between the drive chain 13 and the guide wheel 146 is not tight, causing the drive chain 13 to slip off the guide wheel 146 or deviate, the guide wheel 146 can move within the guide wheel mounting bracket 14 according to the change in the tension of the drive chain 13, so that the guide wheel 146 is slightly closer to the drive chain 13, thereby ensuring that the drive chain 13 and the guide wheel 146 always maintain an appropriate connection position.

[0042] For example, when the connection between the drive chain 13 and the guide wheel 146 is too tight, and the frictional resistance of the drive chain 13 on the guide wheel 146 increases, the guide wheel 146 can move within the guide wheel mounting bracket 14 according to the change in the tension of the drive chain 13, so that the guide wheel 146 moves slightly away from the drive chain 13, thereby allowing the drive chain 13 to always maintain an appropriate connection position with the guide wheel 146.

[0043] In other words, when the tension of the transmission chain 13 changes, causing its connection with the guide wheel 146 to be loose or too tight, the guide wheel mounting bracket 14 is provided, and the guide wheel 146 is movably disposed within the guide wheel mounting bracket 14. This allows the guide wheel 146 to accurately and quickly adjust its position according to the change in the tension applied to it by the transmission chain 13, thereby ensuring that the transmission chain 13 can always maintain a proper connection with it.

[0044] In one embodiment, the guide wheel mounting bracket 14 includes: two main frame bodies 141, a secondary frame body 142, and a fixing member 143. The two main frame bodies 141 are movably connected to the secondary frame body 142, and the main frame body 141 can move back and forth linearly relative to the secondary frame body 142. One of the main frame bodies 141 is fixedly mounted on the fixing member 143.

[0045] Furthermore, a slotted hole is formed in the guide wheel mounting bracket 14, and the guide wheel 146 is mounted in the slotted hole and can move along the direction defined by the slotted hole. Combined with... Figure 4 and Figure 5 The direction in which the strip hole extends is perpendicular to the contact surface between the guide wheel 146 and the transmission chain 13.

[0046] Specifically, the strip-shaped hole includes a first strip-shaped hole 1411, which is disposed on one of its main frames 141; a tension wheel shaft 144 is disposed on the guide wheel 146, which is disposed in the first strip-shaped hole 1411 and can move along the length direction of the first strip-shaped hole 1411; the guide wheel 146 is rotatably disposed on the tension wheel shaft 144, which can save the time of the guide wheel 146 adjusting the transmission chain 13, thereby improving the working efficiency of the sprocket transmission mechanism 10.

[0047] Tension bearings (not shown) are also provided on the two tensioning wheel shafts 144, and the guide wheel 146 is rotatably sleeved on the tension bearings to ensure the stability of the rotation of the guide wheel 146.

[0048] Furthermore, the strip hole also includes a second strip hole 1421, which is provided on the sub-frame 142;

[0049] The guide wheel mounting bracket 14 also includes a double-ended stud 145, which is fixedly connected to the main frame 141 and passes through the second strip hole 1421 of the sub-frame 142, and can move along the length of the second strip hole 1421.

[0050] In this embodiment, the first strip hole 1411 and the second strip hole 1421 can extend in the left and right direction, that is, the direction in which the strip holes extend is perpendicular to the contact surface between the guide wheel 146 and the transmission chain 13.

[0051] Furthermore, both ends of the tension wheel shaft 144 can also be fixedly mounted on the guide wheel mounting bracket 14, such as by directly welding the two ends of the tension wheel shaft 251 to the guide wheel mounting bracket 14.

[0052] In one embodiment, the guide wheel mounting bracket 14 further includes a movable member 147, which is used to abut against the main frame 141 to drive the main frame 141 to move relative to the sub-frame 142.

[0053] Specifically, the movable part 147 can be a screw or a nut.

[0054] By rotating the movable part 147, the main frame 141 can be pushed or pulled relative to the sub-frame 142, thereby adjusting the position of the guide wheel 146.

[0055] The two guide wheels 146 move synchronously under the drive of the subframe 142.

[0056] It should be noted that the main frame 141 has a through hole (not shown) for the movable part 147 to pass through, and the movable part 147 passes through the through hole and abuts against the main frame 141.

[0057] When the movable part 147 is rotated clockwise, the movable part 147 passes through the through hole and abuts against the main frame 141, and pushes the two main frames 142 closer to each other along the length direction of the second strip hole 1421, thereby pushing the two guide wheels 146 slightly closer to the transmission chain 13, so that the transmission chain 13 can always maintain an appropriate connection position with the guide wheels 146.

[0058] When the movable part 147 is rotated counterclockwise, the movable part 147 passes through the through hole and abuts against the main frame 141, and pulls the main frame 142 away from each other along the length direction of the second strip hole 1421, thereby pulling the two guide wheels 146 slightly away from the transmission chain 13, so that the transmission chain 13 can always maintain an appropriate connection position with the guide wheels 146.

[0059] Please see Figure 2 In a second aspect, the present invention provides a drive mechanism 20, which includes a drive motor 21, a support base 22, and a sprocket transmission mechanism 10 of any of the above embodiments. The support base 22 is provided with a bearing 221. One end of the output shaft of the drive motor 21 is sleeved on the inner side of the bearing 22. One end of the sprocket transmission mechanism 10 is connected to the output shaft of the drive motor 21.

[0060] The drive mechanism 20 provided by this utility model adopts the sprocket transmission mechanism 10 of any of the above embodiments. By setting a guide wheel mounting bracket 14 and movably mounting the guide wheel 146 on the guide wheel mounting bracket 14, the guide wheel 146 can adjust its position according to the tension force applied to it by the transmission chain 13, effectively ensuring the stability of the cooperation between the transmission chain 13 and the guide wheel 146, thereby improving the stability of the operation of the sprocket transmission mechanism 10 and making the driving effect more stable and reliable.

[0061] When the drive motor 21 starts running, the output shaft of the drive motor 21 rotates, causing the sprocket transmission mechanism 10 to rotate. Since the output shaft of the drive motor 21 is sleeved inside the bearing 221, the stability of the output shaft of the drive motor 21 within the support 22 is ensured, thereby making the rotation of the output shaft of the drive motor 21 within the support 22 more stable.

[0062] Please see Figure 1 In one specific embodiment, the sprocket drive mechanism 10 further includes a connecting bracket 15 and two drive gear frames 16, with the two ends of the connecting bracket 15 respectively connected to the two drive gear frames 16.

[0063] By connecting the connecting bracket 15 to the two drive gear brackets 16, the rigidity of the entire sprocket drive mechanism 10 can be improved, vibration and deformation can be reduced, and the working stability of the sprocket drive mechanism 10 can be improved.

[0064] Specifically, the two ends of the connecting bracket 15 are fixedly connected to the two drive gear frames 16 respectively, such as by welding to form an integral shape, or by using fasteners (not shown) to assemble the connecting bracket 15 and the drive gear frame 16.

[0065] Furthermore, there are two sprocket drive mechanisms 10, each mounted on a separate drive gear carrier 16. By mounting one sprocket drive mechanism 10 on each of the two drive gear carriers 16, the load on the transmission system can be balanced, thereby reducing the load on a single sprocket drive mechanism 10 and improving the stability and reliability of its operation.

[0066] Please refer to the following: Figure 1 In one embodiment, a support platform 161 is provided on each of the two drive gear carriers 16, and a support seat 22 is provided on the support platform 161. By providing the support platform 161 on the drive gear carrier 16, the support platform 161 is used to ensure the stability of the support seat 22, thereby improving the stability of the output shaft of the drive motor 21 moving within the support seat 22.

[0067] Furthermore, the drive gear carrier 16 is provided with a pair of fixing plates 162, which are located on both sides of the drive motor 21. The fixing plates 162 are fixed to the drive motor 21 by fasteners (not shown).

[0068] Specifically, screws can be used as fasteners. The fixing plate 162 has fixing holes (not shown) for the fasteners to pass through. The fasteners pass through the fixing holes to firmly fix the drive motor 21 on the drive gear carrier 16, which avoids the phenomenon of vibration and deviation of the drive motor 21 during operation, thereby improving the stability of the drive motor 21 operation.

[0069] Please see Figures 6 to 7In a third aspect, the present invention provides a power transmission vehicle 100, which includes: a vehicle body 30, a conductive mechanism 40 and a drive mechanism 20 according to any embodiment. The conductive mechanism 40 is disposed on the vehicle body 30; the drive mechanism 20 is disposed on the vehicle body 30 and is used to drive the power transmission vehicle 100 to move.

[0070] The electric trolley 100 provided by this utility model adopts a drive mechanism 20 with a sprocket transmission mechanism 10 of any of the above embodiments. By setting a guide wheel mounting bracket 14 and movably mounting the guide wheel 146 on the guide wheel mounting bracket 14, the guide wheel 146 can adjust its position according to the tension force applied to it by the transmission chain 13, effectively ensuring the stable cooperation between the transmission chain 13 and the guide wheel 146, thereby improving the stability of the operation of the sprocket transmission mechanism 10, making the movement of the electric trolley 100 more stable, and improving the docking accuracy between the electric trolley 100 and the graphitization furnace.

[0071] Specifically, the vehicle body 30 is provided with a traveling wheel 31, and the other end of the sprocket transmission mechanism 10 is connected to the traveling wheel 31. The drive mechanism 20 drives the sprocket transmission mechanism 10 to move the traveling wheel 31.

[0072] When the drive motor 21 starts running, the output shaft of the drive motor 21 rotates, which drives the drive wheel 11 to rotate. The drive wheel 11 rotates, which in turn drives the driven wheel 12 to rotate. The driven wheel 12 rotates, which in turn drives the traveling wheel 31 to move. In this entire transmission process, the movement of the trolley 100 can be achieved without precise coordination with the gears in the gearbox, which simplifies the overall structure of the trolley 100 and reduces the redundancy of the trolley 100.

[0073] Optionally, when the output shaft of the drive motor 21 rotates clockwise, the drive wheel 11 drives the driven wheel 12 to rotate clockwise, thereby driving the walking wheel 31 to move forward. When the output shaft of the drive motor 21 rotates counterclockwise, the drive wheel 11 drives the driven wheel 12 to rotate counterclockwise, thereby driving the walking wheel 31 to move backward.

[0074] Further, please refer to Figure 7 The conductive mechanism 40 includes: a column 43, an electrode clamping mechanism 41, and a busbar crimping mechanism 42. The electrode clamping mechanism 41 is electrically connected to the busbar crimping mechanism 42. The electrode clamping mechanism 41 is disposed on the column 43, and the busbar crimping mechanism 42 is disposed below the column 43 for crimping the power supply busbar.

[0075] The conductive mechanism 40 includes five columns 43 spaced apart from each other, and two electrode clamping mechanisms 41 are distributed along the length of each column 43 to form a 2*5 rectangular array to correspond to the distribution of conductive electrodes on the graphitization furnace.

[0076] In summary, compared with the prior art, the sprocket transmission mechanism 10 of this utility model, by setting a guide wheel mounting bracket 14 and movably mounting the guide wheel 153 on the guide wheel mounting bracket 14, allows the guide wheel 14 to adjust its position according to the tension force applied to it by the transmission chain 13, thereby ensuring the stable cooperation between the transmission chain 13 and the guide wheel 14 and effectively improving the operational stability of the sprocket transmission mechanism 10.

[0077] Obviously, the above embodiments are merely examples for the detailed description of this utility model, and are not intended to limit the implementation. This utility model can be implemented in many other ways different from those described herein.
