Abstract
Description
Technical Field
[0001] This application relates to the field of material transportation technology, and in particular to an electric material transfer vehicle. Background Technology
[0002] In the industrial production sector, the workshop, as the core location for product manufacturing, directly impacts production progress, product quality, and the overall operating costs of the enterprise due to the efficiency of material flow within it. Material handling, as an indispensable and crucial link in the workshop production process, encompasses multiple scenarios, including the transport of raw materials from storage areas to production lines, the transfer of semi-finished products between various processes, and the transfer of finished products from production lines to storage or shipping areas.
[0003] Currently, manual transport vehicles are still widely used in workshops for material transfer. Although these vehicles are simple in structure and inexpensive, they are entirely driven by human power, resulting in extremely low transfer efficiency, making it difficult to keep up with the fast pace of production. Furthermore, the labor intensity for operators is extremely high, and prolonged operation can easily lead to fatigue, increasing the risk of material collisions and personnel injuries. Against this backdrop, electrifying traditional manual transport vehicles to improve transfer efficiency has become an urgent technical challenge. Simultaneously, the conversion process must consider how to rationally integrate electric components such as motors and batteries while preserving the adaptability of the original manual transport vehicle structure, ensuring that the converted equipment can flexibly cope with complex workshop conditions. The converted transport vehicles must be equipped with a reliable braking system to ensure rapid and precise stopping under full load, downhill, or emergency conditions, eliminating safety hazards such as slippage and collisions. Utility Model Content
[0004] This device provides an electric transport vehicle for material transfer, and the specific implementation method is as follows:
[0005] An electric transport vehicle for material transfer includes:
[0006] The vehicle body and casters located at the bottom of the vehicle body are equipped with a grating for loading materials. The front casters are connected to the motor, and the rear casters are connected to the steering wheel via a steering axle.
[0007] The braking structure and automatic locking assembly are as follows: The braking structure consists of a brake component and a locking component that press against the front caster. The output end of the automatic locking assembly is engaged with the locking component via a meshing disc. The automatic locking assembly includes a cylinder, a rack, and a resilient reset structure. The cylinder arm is connected to the rack and the resilient reset structure, and the rack is actively engaged with the meshing disc. The extension and retraction of the cylinder arm drives the braking structure to stop the caster.
[0008] Preferably, it also includes a controller, the signal input terminal of which is connected to the electric drive pedal of the vehicle body, and the signal output terminal of which is electrically connected to the motor and cylinder.
[0009] Preferably, it also includes a battery, which is electrically connected to the battery, controller and cylinder.
[0010] Based on the above technical solutions, the efficient transfer of materials is achieved by equipping the vehicle body with electric drive; and the automatic locking components and locking parts, with the linkage design with the electric pedal of the vehicle body, can automatically trigger the locking action after the vehicle body stops, thereby effectively ensuring the overall stability of the vehicle body when it is stationary.
[0011] Preferably, the caster is connected to the vehicle body via a caster seat, and a brake component is vertically slidably connected to the side of the caster seat. The brake component consists of an L-shaped brake pad and a sliding plate.
[0012] Preferably, the side of the caster seat is also rotatably connected to a locking element for controlling the raising and lowering of the brake element, and the locking element and the brake element form a linkage structure.
[0013] Preferably, the locking member has an inner toothed ring along the circumferential direction on its inner side, and the engagement disc includes a first outer toothed ring and a circumferential toothed groove coaxially integrated. The first outer toothed ring meshes with the rack, and the circumferential toothed groove is inserted into the inner toothed ring.
[0014] Based on the above technical solutions, the braking and locking components adopt the existing conventional non-powered vehicle body's braking structure. By modifying the locking components and adding a biting disc and automatic locking assembly, the electrification upgrade of the existing non-powered vehicle body has been successfully achieved.
[0015] Preferably, the automatic locking assembly has a box-type structure, with the cylinder, rack, and elastic reset structure all vertically arranged inside the box-type structure. The elastic reset structure includes a guide rod and a reset spring sleeved on the outside of the guide rod. One side of the rack is connected to the cylinder through a first linkage plate, and the other side of the rack is connected to a second linkage plate. The second linkage plate is slidably connected to the guide rod, and the bottom of the second linkage plate abuts against the reset spring.
[0016] Based on the above technical solutions, the cylinder is designed to achieve linkage control with the electric pedal: when the electric pedal is released, the cylinder responds to the action through the controller, and when the vehicle is stopped, the air arm extends and works with the automatic door locking component to complete the quick locking; when the electric pedal is pressed down, the cylinder unlocking air arm and the return spring will push up the rack, thereby driving the automatic door locking component to unlock in real time.
[0017] Preferably, the vehicle body has two layout configurations, namely:
[0018] Firstly, the vehicle body is also equipped with a transmission box, through which the input end of the steering axle is connected to the steering wheel.
[0019] Secondly, the vehicle body is also equipped with a transmission box, and the transmission box has a passenger space.
[0020] Based on the above technical solutions, the electric drive pedal, steering axle, and transmission box all adopt the transmission structure of a conventional vehicle body. The steering wheel controls the steering axle to achieve caster wheel steering. The vehicle body can be flexibly configured with a passenger space for people to sit in, or the passenger space can be eliminated. When the passenger space is eliminated, the worker pushes the vehicle body, and the vehicle body will automatically provide assistance. In the absence of a passenger space, the steering wheel does not need to be a disc structure and can be designed as a handle. The electric drive pedal can also be integrated into the handle for easy pushing and operation by the worker.
[0021] Preferably, the top of the grille is provided with a locating pin along its circumference upwards.
[0022] In summary, this application includes the following beneficial technical effects:
[0023] 1. This utility model achieves efficient material transfer by setting up an electrically driven vehicle body. By setting up an automatic locking component and locking parts in conjunction with the electric drive pedal of the vehicle body, the automatic locking component can automatically lock after the vehicle body stops, thereby ensuring the overall stability of the vehicle body when it stops.
[0024] 2. This utility model uses a cylinder to control the electric pedal when it is released, so that the vehicle can stop at any time and the automatic locking component can lock in time. When the electric pedal is pressed down, the rack is lifted by the return spring to unlock the automatic locking component in real time.
[0025] 3. This utility model has a simple structure. By modifying the locking parts, adding a biting plate and an automatic locking component, it achieves electrification based on the existing unpowered vehicle body. Moreover, the vehicle body adopts a front-drive motor and rear-mounted steering to obtain better driving visibility and can flexibly cope with complex road conditions in the workshop.

[0044] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0045] This application discloses an electric transport vehicle for material transfer.
[0046] Example 1
[0047] Reference Figures 1 to 6 This embodiment discloses an electric transport vehicle for material transfer, including a controller, a braking structure, an automatic locking assembly 3, a vehicle body 1, and casters 2 located at the bottom of the vehicle body 1. The vehicle body 1 is equipped with a loading grille 5. The front casters 2 are connected to a motor 4, and the rear casters 2 are connected to a steering wheel 13 via a steering axle 11. The braking structure consists of a brake element 7 and a locking element 8 that press against the front casters 2. The output end of the automatic locking assembly 3 is engaged with the locking element 8 via a meshing disc 9. The system includes a cylinder 301, a rack 303, and an elastic reset structure. The arm of the cylinder 301 is connected to the rack 303 and the elastic reset structure, and the rack 303 is actively engaged with the engagement disc 9. The extension and retraction of the arm of the cylinder 301 drives the brake structure to stop the caster 2. In this structure, the signal input terminal of the controller is connected to the electric drive pedal of the vehicle body 1, and the signal output terminal of the controller is electrically connected to the motor 4 and the cylinder 301. In this structure, the battery 10 is electrically connected to the battery 10, the controller, and the cylinder 301.
[0048] The automatic locking assembly 3 has a box-shaped structure. The cylinder 301, rack 303 and elastic reset structure are all vertically arranged inside the box-shaped structure. The elastic reset structure includes a guide rod 304 and a reset spring 305 sleeved on the outside of the guide rod 304. One side of the rack 303 is connected to the cylinder 301 through the first linkage plate 302, and the other side of the rack 303 is connected to the second linkage plate 306. The second linkage plate 306 is slidably connected to the guide rod 304, and the bottom of the second linkage plate 306 abuts against the reset spring 305.
[0049] Caster 2 is connected to vehicle body 1 via caster seat 6. A brake component 7 is vertically slidably connected to the side of caster seat 6. The brake component 7 consists of an L-shaped brake pad 701 and a sliding plate 702. In this structure, a first guide block 703 and a second guide block 704 are respectively provided above and below the sliding plate 702. The top arc-shaped structure of locking component 8 abuts against the first guide block 703, and the bottom end of locking component 8 is connected to the second guide block 704 via a stepped groove 802. Rotation causes the stepped groove 802 to act on the second guide block 704 at different positions, thereby driving the brake pad 701 to act on the caster 2. Conventional locking parts 8 have foot pedals on both sides. This locking part 8 removes the foot pedals and adds an internal toothed ring 801 to the inside. This locking part 8 can also retain the foot pedals. When the rack 303 disengages from the first external toothed ring 901, the foot pedals of the locking part 8 can be manually pressed to achieve manual locking. However, the locking part 8 needs to be reset afterward.
[0050] The side of the caster wheel seat 6 is also rotatably connected to a locking member 8 for controlling the lifting and lowering of the brake member 7. The locking member 8 and the brake member 7 form a linkage structure. The inner side of the locking member 8 is provided with an inner toothed ring 801 along the circumferential direction. The engagement disc 9 includes a first outer toothed ring 901 and an circumferential toothed groove 902 coaxially integrated. The first outer toothed ring 901 meshes with the rack 303, and the circumferential toothed groove 902 is inserted into the inner toothed ring 801. In this structure, any shape of concave and convex structure can also be provided between the circumferential toothed groove 902 and the inner toothed ring 801, so that the locking member 8 can be driven to rotate by the rotation of the engagement disc 9.
[0051] The specific implementation process is as follows: After materials are loaded into the grille 5, they are transferred; the vehicle body 1 is a front-wheel drive structure. After the electric pedal is pressed, the motor 4 drives the vehicle body 1 and the casters 2 to move forward; after the electric pedal is pressed, the controller controls the cylinder 301 to retract the air arm, and the return spring 305 pushes the rack 303 upward; during this period, the locking part 8 rotates, and under the action of the step groove 802 and the second guide block 704, the brake pad 701 is lifted upward, and the casters 2 are unlocked; when the vehicle body 1 stops, the electric pedal is released, the controller controls the cylinder 301 to extend the air arm, and the brake pad 701 presses down on the casters 2 to lock the vehicle body 1, so as to improve the stability of the vehicle body 1 when loading materials.
[0052] Example 2
[0053] Reference Figures 1 to 6 Based on the above embodiments, this embodiment also discloses an electric transport vehicle for material transfer. The vehicle body 1 is also provided with a transmission box 12. The input end of the steering axle 11 is connected to the steering wheel 13 through the transmission box 12. The top of the grille 5 is provided with a positioning pin 501 along its circumference. In this structure, the positioning pin 501 is used for the installation of packaging bags. The packaging bags are provided with positioning holes. When the material particles are small, the material can be prevented from leaking out by adding packaging bags.
[0054] Example 3
[0055] Reference Figure 7 Unlike the above embodiments, this embodiment also discloses an electric transport vehicle for material transfer, wherein the vehicle body 1 is also provided with a transmission box 12, and the transmission box 12 is provided with a passenger space 1201.
[0056] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
