Description

Technical Field

[0001] This utility model relates to the field of logistics handling equipment technology, and in particular to a waterproof new energy logistics drive mechanism device. Background Technology

[0002] Traditional handcarts in the workshop rely entirely on manual pushing, resulting in high labor intensity for workers and impacting cart transfer efficiency. Adding electric drive wheels to the handcarts can significantly reduce the labor intensity of workers and improve cart transfer efficiency within the workshop.

[0003] However, electric carts operating in workshops are prone to contact with liquids such as cutting fluid and coolant. The motors and control circuits inside these carts are sensitive to water; direct contact with water can cause serious malfunctions such as short circuits and circuit burnout, posing safety hazards and significantly limiting the application scenarios of electric carts.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a waterproof new energy logistics drive mechanism device to improve the waterproof performance of the device.

[0006] The technical solution of this utility model is as follows: The waterproof new energy logistics drive mechanism includes a trolley body, a rotary drive mechanism mounted on the trolley body, a drive wheel connected to the rotary drive mechanism, and a connecting cover. The drive wheel is fitted onto and rotatably connected to the rotary drive mechanism. The connecting cover connects the rotary shafts of both the drive wheel and the rotary drive mechanism, and covers and seals the portion of the rotary drive mechanism near the rotary shaft of the drive wheel. A seal is provided between the drive wheel and the rotary drive mechanism.

[0007] A further technical solution involves placing a bearing between the drive wheel and the rotary drive mechanism. The seal is located on the side of the bearing furthest from the connecting cover.

[0008] The further technical solution is that the sealing element is a double-lip oil seal with a dustproof lip.

[0009] A further technical solution is that the rotary drive mechanism includes a motor and a gear reducer connected to the motor shaft. The rotating shaft is the gear shaft of the gear reducer.

[0010] A further technical solution involves setting an annular step on the surface of the motor around the axis of rotation, with the bearing abutting against the step.

[0011] A further technical solution involves providing a connecting seat on the main body of the vehicle. The rotary drive mechanism is mounted on the connecting seat.

[0012] A further technical solution involves extending the connecting seat along the axial direction of the drive wheel to form an axial extension. The axial extension extends between the drive wheel and the rotary drive mechanism.

[0013] A further technical solution involves a radially extending portion extending radially along the axis of the rotation shaft. A connecting cover connects to the radially extending portion.

[0014] A further technical solution involves circumferentially evenly arranging at least two threaded fasteners around the axis of rotation of the connecting cover. These threaded fasteners connect to the drive wheel.

[0015] A further technical solution involves providing driven wheels and tie rods on the main body of the vehicle. The driven wheels and driving wheels are positioned on the same horizontal plane.

[0016] The beneficial technical effects of this utility model are as follows: (1) The waterproof new energy logistics drive mechanism device of this utility model is equipped with an active drive wheel, which is connected to a rotary drive mechanism. The rotary drive mechanism drives the active drive wheel to rotate, thereby moving the main body of the trolley and reducing the burden on the operator of the waterproof new energy logistics drive mechanism device. The rotary drive mechanism is equipped with a connecting cover, which connects the rotating shaft and the drive wheel. The active drive wheel is rotated and fitted onto the rotary drive mechanism. A sealing element is also provided between the active drive wheel and the rotary drive mechanism. That is, the connecting cover and the active drive wheel cooperate to cover one side of the rotating shaft of the sealed rotary drive mechanism, preventing water from flowing into the rotary drive mechanism along the rotating shaft and damaging the electronic components inside the rotary drive mechanism, thereby improving the waterproof performance of the rotary drive mechanism and thus improving the waterproof performance of the entire waterproof new energy logistics drive mechanism device.

[0017] (2) Furthermore, the seal is located on the side of the bearing away from the connecting cover, and the seal is a double-lip oil seal with a dustproof lip. The seal prevents lubricating oil leakage at the bearing location while enhancing the waterproof performance of the gap between the drive wheel and the motor.

[0018] (3) Furthermore, the axial extension increases the contact area between the connecting seat and the motor, improving the stability of the connection between the motor and the connecting seat. In addition, the axial extension extending between the drive wheel and the rotary drive mechanism can limit the position of the seal, ensuring that the seal stably seals the gap between the drive wheel and the rotary drive mechanism, and ensuring the sealing performance between the drive wheel and the rotary drive mechanism.

[0025] Figure 1 The diagram shows a three-dimensional structural schematic of a waterproof new energy logistics drive mechanism device according to an embodiment of the present disclosure, viewed from below. Figure 2 A three-dimensional structural schematic diagram of a waterproof new energy logistics drive mechanism device according to an embodiment of the present disclosure is shown, with the main body of the vehicle hidden. Figure 3A waterproof new energy logistics drive mechanism device according to an embodiment of this disclosure is shown, with a vertical cross-sectional view of the trolley body hidden. Please refer to... Figure 1 , Figure 2 and Figure 3 The waterproof new energy logistics drive mechanism includes a trolley body 1, a rotary drive mechanism 3 mounted on the trolley body 1, an active drive wheel 5 connected to the rotary drive mechanism 3, and a connecting cover 4. The active drive wheel 5 is mounted on and rotatably connected to the rotary drive mechanism 3. The rotary drive mechanism 3 drives the active drive wheel 5 to rotate, thereby moving the trolley body 1 and reducing the workload of the operator. The connecting cover 4 connects the active drive wheel 5 and the rotary shaft 31 of the rotary drive mechanism 3, covering and sealing the portion of the rotary drive mechanism 3 near the rotary shaft 31. A seal 51 is provided between the active drive wheel 5 and the rotary drive mechanism 3, meaning that the connecting cover 4 and the active drive wheel 5 cooperate to cover and seal one side of the rotary shaft 31 of the rotary drive mechanism, preventing water from flowing into the rotary drive mechanism 3 along the rotary shaft 31 and damaging the electronic components inside the rotary drive mechanism 3, thus improving the waterproof performance of the rotary drive mechanism 3 and consequently improving the overall waterproof performance of the waterproof new energy logistics drive mechanism.

[0026] Please refer to Figure 1 and Figure 3 The rotary drive mechanism 3 includes a motor 32 and a gear reducer 33 connected to the motor shaft 322 of the motor 32. The motor shaft 322 and the gear reducer 33 can be connected by a key (not shown in the figure). The rotating shaft 31 is the gear shaft of the gear reducer 33. The motor 32 features smooth start-up and high controllability, suitable for short-distance, high-frequency use of trolleys within a workshop. The gear reducer 33 adjusts the speed of the motor 32 through the transmission ratio between the meshing gears inside. Adjusting the transmission ratio reduces the output speed of the motor 32 and increases the output torque of the motor 32, providing sufficient torque to drive the movement of the loaded trolley body 1.

[0027] Preferably, a radial extension portion 331 is provided radially extending on the rotating shaft 31 about its axis. The connecting cover 4 is connected to the radial extension portion 331. The radial extension portion 331 increases the contact area between the rotating shaft 31 and the connecting cover 4, improving the stability of the connecting cover 4 when it is fixed. In some embodiments, the connecting cover 4 and the rotating shaft 31 can be connected by screws.

[0028] More preferably, at least two threaded fasteners 41 are evenly arranged circumferentially around the axis of the rotation shaft 31. The threaded fasteners 41 connect to the drive wheel 5. In some embodiments, the threaded fasteners 41 can be threaded fasteners known in the prior art, such as screws or bolts. The two or more threaded fasteners 41 work together to fix the connecting cover 4 and the drive wheel 5, ensuring the connection strength between the connecting cover 4 and the drive wheel 5. At the same time, the multiple threaded fasteners 41 are evenly distributed to ensure a tight fit between the connecting cover 4 and the drive wheel 5, ensuring the sealing performance between the connecting cover 4 and the drive wheel 5.

[0029] In some embodiments, sealant may be filled between the connecting cover 4 and the drive wheel 5 to further enhance the waterproof performance of the waterproof new energy logistics drive mechanism.

[0030] Please refer to Figure 1 and Figure 3 A bearing 6 is provided between the drive wheel 5 and the rotary drive mechanism 3 to rotatably connect them. A seal 51 is located on the side of the bearing 6 away from the connecting cover 4. Specifically, the seal 51 is a double-lip oil seal with a dustproof lip. The seal 51 prevents lubricating oil leakage at the bearing 6 location while enhancing the waterproof performance of the gap between the drive wheel 5 and the motor 32.

[0031] Preferably, an annular step 321 is provided on the surface of the motor 32 about the axis of rotation 31, and the bearing 6 abuts against the step 321 to limit the axial position of the bearing 6. In some embodiments, a retaining ring 52 may also be provided between the drive wheel 5 and the motor 32. Correspondingly, an annular groove (not shown in the figure) is provided on the drive wheel 5 or the motor 32 about the axis of the drive wheel 5 for the retaining ring to engage. The retaining ring 52 and the step 321 are located on opposite sides of the axial direction of the bearing 6 to fix the axial position of the bearing 6.

[0032] In some embodiments, a wheel seat 53 is also fitted onto the motor 32. A bearing 6 is disposed between the wheel seat 53 and the motor 32, and the drive wheel 5 is mounted on the wheel seat 53. The drive wheel 5 experiences severe wear in contact with the ground and requires frequent replacement, while the wheel seat 53 needs to be fitted with the bearing 6, thus requiring high machining precision. The separate arrangement of the drive wheel 5 and the wheel assembly reduces the maintenance costs of the waterproof new energy logistics drive mechanism.

[0033] Please refer to Figure 1 and Figure 3The trolley body 1 is also equipped with a connecting seat 2. The rotary drive mechanism 3 is mounted on the connecting seat 2. The shape of the connecting seat 2 can match the shape of the rotary drive mechanism 3. When the rotary drive mechanism 3 is a motor 32 and a gear reducer 33, the connecting seat 2 is connected to the motor 32. Specifically, the connecting seat 2 can fix the motor 32 to the rotary drive mechanism 3 by means of a clamp, and the clamp and the connecting seat 2 can be connected by screws (not shown in the figure).

[0034] Preferably, along the axial direction of the drive wheel 5, the connecting seat 2 extends towards the drive wheel 5 to form an axial extension 21. The axial extension 21 extends between the drive wheel 5 and the rotary drive mechanism 3. The axial extension 21 increases the contact area between the connecting seat 2 and the motor 32, improving the stability of the connection between the motor 32 and the connecting seat 2. Furthermore, the axial extension 21 extending between the drive wheel 5 and the rotary drive mechanism 3 can limit the position of the seal 51, ensuring that the seal 51 stably seals the gap between the drive wheel 5 and the rotary drive mechanism 3, thus guaranteeing the sealing performance between the drive wheel 5 and the rotary drive mechanism 3.

[0035] More preferably, the trolley body 1 is also equipped with driven wheels 12 and a pull rod 11. The driven wheels 12 and the driving wheels 5 are arranged on the same horizontal plane, and the driven wheels 12 and the driving wheels 5 together support the trolley body 1. When the driving wheels 5 are driven to rotate, they drive the driven wheels 12 to rotate synchronously, thereby moving the trolley body 1. The pull rod 11 is arranged facing upwards for easy gripping by the operator. The operator can easily pull or push the trolley body 1 by pushing or pulling the pull rod 11, facilitating operation.

[0036] The specific workflow of this utility model is as follows: When the main body 1 of the drive trolley moves, the motor 32 is started. The motor 32 outputs torque and transmits it to the drive wheel 5 through the gear reducer 33 and the connecting cover 4. During this process, the drive wheel 5 and the connecting cover 4 cooperate to seal the entire output end of the motor 32. External water is blocked by the connecting cover 4 and the drive wheel 5, and water in the gap between the drive wheel 5 and the motor 32 is blocked by the seal 51, preventing water from contacting the rotary drive mechanism 3.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
