Description
Technical Field
[0001] This utility model relates to the field of press technology, and in particular to a press containing a reversing alarm. Background Technology
[0002] In the field of agricultural mechanization, soil compactors are widely used soil treatment equipment, mainly used to compact soil, level the surface, and promote close contact between seeds and soil, thereby improving crop germination rate and growth quality. However, existing soil compactors generally lack reversing alarm devices, resulting in significant safety hazards when reversing. Especially in situations with many people on the work site or poor visibility, operators find it difficult to accurately judge the reversing path, easily leading to collisions or crushing accidents, causing damage to personnel and equipment. Therefore, there is a need to develop a soil compactor equipped with a reversing alarm.
[0003] Roller presses typically require frequent forward and reverse maneuvers during operation to adapt to varying working environments and needs. However, in current technology, reversing alarm devices are mostly integrated into the vehicle's electronic control system, necessitating modifications to the internal circuitry and increasing the design complexity and manufacturing cost of the equipment. For agricultural machinery like roller presses, given their harsh working environment and high usage frequency, complex circuit modifications not only increase the risk of malfunctions but also raise maintenance difficulties. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a press machine with a reversing alarm, which aims to improve the problem that in the existing technology, reversing alarm devices are mostly integrated into the vehicle's electronic control system, which requires modification of the internal circuitry and increases the design complexity and manufacturing cost of the equipment.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a press machine containing a reversing alarm, comprising a press machine body, the press machine body including an independent power supply module, the independent power supply module being electrically connected to an audible and visual alarm module, a reverse gear trigger linkage module, an environmental perception module, an obstacle detection module, and a path prompting module, the output terminal of the reverse gear trigger linkage module being connected to the input terminal of the audible and visual alarm module, the output terminal of the reverse gear trigger linkage module being connected to the input terminal of the environmental perception module, the output terminal of the reverse gear trigger linkage module being connected to the input terminal of the obstacle detection module, the output terminal of the reverse gear trigger linkage module being connected to the input terminal of the path prompting module, the output terminal of the environmental perception module being connected to the signal receiving terminal of the obstacle detection module, the output terminal of the environmental perception module being connected to the input terminal of the path prompting module, the output terminal of the obstacle detection module being connected to the input terminal of the path prompting module, the path prompting module and the audible and visual alarm module being bidirectionally connected, and the output terminal of the obstacle detection module being connected to the input terminal of the audible and visual alarm module.
[0006] The above technical solution enables the simultaneous activation of the audible and visual alarm module, environmental perception module, obstacle detection module, and path prompt module via the reverse gear trigger linkage module. This ensures that the entire system instantly enters working mode when the vehicle enters reverse gear, avoiding safety blind spots caused by module startup delays.
[0007] As a further description of the above technical solution:
[0008] The audible and visual alarm module includes a buzzer, an LED warning light, and an audible and visual control circuit. The reverse gear trigger linkage module includes a Hall sensor and a signal transmission circuit. The environmental perception module includes an ultrasonic sensor and a signal processing unit. The output of the ultrasonic sensor is connected to the input of the signal processing unit. The obstacle detection module includes a data analysis and processing circuit. The path prompting module includes a laser marker and a path prompting control circuit. The power input of the laser marker is electrically connected to the output of the path prompting control circuit.
[0009] The above technical solution involves using a Hall sensor to detect the triggering of the reverse gear signal, then using an ultrasonic sensor to perceive the surrounding environment in real time while reversing and transmitting the data to a signal processing unit. After the data analysis and processing circuit determines the risk of obstacles, the buzzer and LED warning lights in the audible and visual alarm module issue a warning. At the same time, the path guidance module projects a safe path trajectory through a laser marker, realizing environmental monitoring, collision warning, and path guidance during the reversing process, thereby effectively improving reversing safety and operational convenience.
[0010] As a further description of the above technical solution:
[0011] The signal output terminal of the signal transmission circuit of the reverse gear trigger linkage module is connected to the input terminal of the sound and light control circuit of the sound and light alarm module and the path prompt control circuit of the path prompt module, respectively. The output terminal of the signal processing unit of the environmental perception module is connected to the data analysis and processing circuit of the obstacle detection module.
[0012] The above technical solution involves directly connecting the signal transmission circuit of the reverse gear trigger linkage module to the audible and visual control circuit of the audible and visual alarm module and the path prompting control circuit of the path prompting module. This ensures that when the vehicle enters reverse gear, the audible and visual alarm module quickly enters a standby state, preparing to receive risk signals and trigger the alarm. Simultaneously, the path prompting control circuit of the path prompting module is activated, allowing it to receive path parameters and drive the laser marker. This ensures the immediate activation of critical response modules in reverse gear scenarios, avoiding safety hazards caused by delayed activation. The raw data collected by the environmental perception module can be directly transmitted to the data analysis and processing circuit of the obstacle detection module for analysis, providing a basis for risk assessment and path prompting planning.
[0013] As a further description of the above technical solution:
[0014] The data analysis and processing circuit of the obstacle detection module is connected to the sound and light control circuit of the sound and light alarm module. The output signal of the data analysis and processing circuit of the obstacle detection module is connected to the data receiving end of the path prompting control circuit of the path prompting module. The output signal of the path prompting control circuit is connected to the receiving end of the data analysis and processing circuit of the obstacle detection module.
[0015] Through the above technical solution: the audible and visual alarm module achieves graded alarms by using risk signals from the obstacle detection module and status feedback from the path prompting module, thus intuitively reminding the driver of different driving risks. After analyzing the data, the obstacle detection module can provide accurate obstacle information to the path prompting module to ensure that the subsequent response is more in line with the actual environment. If the path prompting module finds that the planned path is blocked by a new obstacle during execution, it can immediately provide feedback to the obstacle detection module. Then, the obstacle detection module can re-analyze the environmental data based on the feedback and correct the reversing path, thereby significantly improving the safety and user experience of the reversing assistance system.
[0016] As a further description of the above technical solution:
[0017] The press body has an internal support frame, the lower surface of which is fixedly connected to a gearbox, and the outer wall of which is fixedly connected to a fixing block.
[0018] Through the above technical solution: the support frame can play a role in fixing and supporting the gearbox, and the gearbox plays a role in fixing and supporting the fixed block. When the operator engages reverse gear, the reverse gear mechanism of the gearbox triggers the alarm through mechanical linkage, causing it to emit an audible and visual alarm signal.
[0019] As a further description of the above technical solution:
[0020] The fixed block has a sliding groove inside, and a threaded shaft is threadedly connected inside the fixed block. A rotating block is fixedly connected to the upper surface of the threaded shaft, and a connecting plate is fixedly connected to the lower surface of the threaded shaft. The outer wall of the connecting plate is slidably connected to the inner wall of the sliding groove.
[0021] The above technical solution allows the rotating block to rotate, causing the threaded shaft to rotate inside the fixed block. The rotation of the threaded shaft then causes the connecting plate to slide within the sliding groove.
[0022] As a further description of the above technical solution:
[0023] One end of a spring is fixedly connected to the lower surface of the connecting plate, and the other end of the spring is fixedly connected to a sliding block. The outer wall of the sliding block is slidably connected to the inner wall of the sliding groove.
[0024] Through the above technical solution: the movement of the connecting plate can drive the spring to compress or stretch, and then the spring drives the sliding block to slide within the inner wall of the sliding groove.
[0025] As a further description of the above technical solution:
[0026] The lower surface of the sliding block is fixedly connected to a ball bearing one. The outer wall of the ball bearing one is slidably connected to the inner wall of the sliding groove. The outer wall of the ball bearing one is rotatably connected to a ball bearing two. The outer wall of the ball bearing two is clamped to a clamping block. The audible and visual alarm module is located on the outer wall of the clamping block.
[0027] Through the above technical solution: the sliding block can be pushed by the first ball to the second ball, and then the second ball is pushed into the inside of the clamping block, so that the clamping block is locked and fixed by the second ball, and then the audible and visual alarm module can be fixed by the clamping block.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, by installing a reversing alarm, an audible and visual alarm signal can be emitted in a timely manner when reversing, alerting surrounding personnel and significantly reducing the probability of collision or crushing accidents.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0044] Reference Figure 1 This utility model provides an embodiment of a press machine containing a reversing alarm, comprising a press machine body 1. The press machine body 1 includes an independent power supply module, which is electrically connected to an audible and visual alarm module 6, a reverse gear trigger linkage module, an environmental perception module, an obstacle detection module, and a path prompting module. The output signal of the reverse gear trigger linkage module is connected to the input signal of the audible and visual alarm module 6, the output signal of the reverse gear trigger linkage module is connected to the input signal of the environmental perception module, the output signal of the reverse gear trigger linkage module is connected to the input signal of the obstacle detection module, the output signal of the reverse gear trigger linkage module is connected to the input signal of the path prompting module, the output signal of the environmental perception module is connected to the signal receiving end of the obstacle detection module, the output signal of the environmental perception module is connected to the input signal of the path prompting module, the output signal of the obstacle detection module is connected to the input signal of the path prompting module, the path prompting module and the audible and visual alarm module 6 are bidirectionally connected, and the output signal of the obstacle detection module is connected to the input signal of the audible and visual alarm module 6.
[0045] Specifically, by adopting an independent power supply, the structure is simple and suitable for various harsh agricultural operating environments. The independent power supply module can provide power to other modules on demand. After the reverse gear is triggered, the reverse gear trigger linkage module can synchronously output a reverse gear activation signal to the audible and visual alarm module 6, the environmental perception module, the obstacle detection module, and the path prompting module, thereby ensuring that all modules start simultaneously when reverse gear is engaged, avoiding delayed response from some modules. The environmental perception module can transmit the collected rear distance data and obstacle information to the obstacle detection module, providing analysis basis for the obstacle detection module. The environmental perception module can also transmit the detected surrounding environment information to the path prompting module, assisting the path prompting module to work more accurately. The obstacle detection module can transmit the detected obstacle position information to the path prompting module, allowing the path prompting module to adjust the path prompting method based on this information. When the path prompting module detects a potential problem with the reverse path, it can send an alarm signal to the audible and visual alarm module 6, achieving a dual reminder effect. Furthermore, the obstacle detection module can send a control signal to the audible and visual alarm module 6 based on the detected obstacle distance information.
[0046] Reference Figures 1-6 The sound and light alarm module 6 includes a buzzer, an LED warning light, and a sound and light control circuit; the reverse gear trigger linkage module includes a Hall sensor and a signal transmission circuit; the environmental perception module includes an ultrasonic sensor and a signal processing unit, with the output of the ultrasonic sensor connected to the input of the signal processing unit; the obstacle detection module includes a data analysis and processing circuit; and the path prompting module includes a laser marker and a path prompting control circuit, with the power input of the laser marker electrically connected to the output of the path prompting control circuit.
[0047] Specifically, when the system detects an obstacle or reverse gear is triggered, the buzzer is driven by the sound and light control circuit to sound an alarm, and the LED warning light flashes to remind the driver to pay attention to the surrounding environment. The sound and light signals emitted by the sound and light alarm module 6 can effectively remind people around to pay attention to the reversing operation and reduce the risk of accidents. The Hall sensor can detect the signal that the vehicle is in reverse gear, and then transmit it to other modules through the signal transmission circuit. The ultrasonic sensor can emit and receive reflected signals to detect the distance of obstacles around the vehicle. Then, the signal processing unit filters, amplifies and calculates the original signal to generate obstacle distance and position information, thereby providing accurate environmental data for the obstacle detection module. The data analysis and processing circuit receives data from the environmental perception module and, through the detection algorithm unit, determines whether there is an obstacle, providing a basis for subsequent alarms and prompts. The path prompting module can drive the laser marker to project the reversing path or safety area markings through the path prompting control circuit according to the obstacle detection results or reverse gear signal, thereby helping the driver to intuitively judge the reversing trajectory and obstacle position and improve the operation accuracy.
[0048] Reference Figures 1-5 The signal output terminal of the signal transmission circuit of the reverse gear trigger linkage module is connected to the input terminal of the sound and light control circuit of the sound and light alarm module 6 and the path prompt control circuit of the path prompt module, respectively. The output terminal of the signal processing unit of the environmental perception module is connected to the data analysis and processing circuit of the obstacle detection module. The data analysis and processing circuit of the obstacle detection module is connected to the sound and light control circuit of the sound and light alarm module 6. The output terminal of the data analysis and processing circuit of the obstacle detection module is connected to the data receiving terminal of the path prompt control circuit of the path prompt module. The output terminal of the path prompt control circuit is connected to the receiving terminal of the data analysis and processing circuit of the obstacle detection module.
[0049] Specifically, when the vehicle engages reverse gear, the reverse gear signal output by the Hall sensor of the reverse gear trigger linkage module is transmitted to the audible and visual control circuit via the signal transmission circuit. This directly triggers the audible and visual alarm module 6 to activate, immediately emitting a reversing warning sound and illuminating the warning lights via a buzzer and LED warning lights to alert surrounding personnel to the vehicle's movement. Simultaneously, the signal transmission circuit triggers the path indication control circuit, which in turn activates the laser marker to project a safe reversing path. This provides the driver with a clear reference for the reversing trajectory, reducing operational difficulty. Furthermore, the system can activate synchronously with the audible and visual alarm module 6, thus forming a [missing information - likely a system or mechanism]. With dual auditory and visual cues, the environmental perception module's signal processing unit converts raw data collected by the ultrasonic sensor into distance information, which is then transmitted to the obstacle detection module. This allows the obstacle detection module to determine the danger level based on the distance data and output corresponding control signals to the audio-visual control circuit to activate the alarm. Simultaneously, when an obstacle is detected encroaching on the preset path, the data analysis circuit sends a path adjustment command to the path prompting control circuit. This dynamically adjusts the projection angle or range of the laser marker to avoid the obstacle. Furthermore, the path prompting control circuit can feed back the laser projection status to the obstacle detection module for auxiliary judgment, improving the accuracy of the judgment.
[0050] Reference Figures 6-10 The press body 1 has a support frame 2 inside. A gearbox 3 is fixedly connected to the lower surface of the support frame 2. A fixing block 5 is fixedly connected to the outer wall of the gearbox 3. A sliding groove 14 is opened inside the fixing block 5. A threaded shaft 8 is threadedly connected inside the fixing block 5. A rotating block 7 is fixedly connected to the upper surface of the threaded shaft 8. A connecting plate 9 is fixedly connected to the lower surface of the threaded shaft 8. The outer wall of the connecting plate 9 is slidably connected to the inner wall of the sliding groove 14. One end of a spring 10 is fixedly connected to the lower surface of the connecting plate 9. A sliding block 11 is fixedly connected to the other end of the spring 10. The outer wall of the sliding block 11 is slidably connected to the inner wall of the sliding groove 14. A ball bearing 12 is fixedly connected to the lower surface of the sliding block 11. The outer wall of the ball bearing 12 is slidably connected to the inner wall of the sliding groove 14. A ball bearing 13 is rotatably connected to the outer wall of the ball bearing 12. A clamping block 4 is clamped to the outer wall of the ball bearing 13. An audible and visual alarm module 6 is set on the outer wall of the clamping block 4.
[0051] Specifically, the support frame 2 fixes the position of the gearbox 3, which in turn fixes the position of the fixing block 5. The sliding groove 14 inside the fixing block 5 facilitates the threaded shaft 8's threaded rotation within the fixing block 5. Simultaneously, rotating the rotating block 7 causes the threaded shaft 8 to rotate within the fixing block 5. This rotation of the threaded shaft 8 causes the connecting plate 9 to slide up and down within the sliding groove 14. The sliding of the connecting plate 9 compresses the spring 10, thereby... The compression of the sliding block 11 causes it to slide inside the sliding groove 14. The sliding of the sliding block 11 causes the first ball 12 to push the second ball 13, thus squeezing part of the second ball 13 into the clamping block 4. The second ball 13 then engages the clamping block 4, which in turn fixes the position of the sound and light alarm module 6. This design is suitable for different installation scenarios, can be fixed without complicated tools, and allows for quick removal of the device for cleaning, component replacement, or circuit testing, avoiding maintenance delays caused by disassembly difficulties.
[0052] Working Principle: During operation, the reverse gear trigger linkage module first receives the vehicle's reverse gear signal and then sends start commands to the audible and visual alarm module 6 and the path indication module via its signal transmission circuit. Simultaneously, the ultrasonic sensor of the environmental perception module collects real-time data on the environment behind and around the vehicle and transmits the raw data to the data analysis and processing circuit of the obstacle detection module. This data analysis provides a basis for subsequent warnings and path planning. If the obstacle detection module determines that there is an obstacle risk, it immediately sends a signal to the control circuit of the audible and visual alarm module 6, triggering the buzzer to sound and the warning light to flash, thus alerting the driver through an audible and visual alarm. While being aware of the risks, the obstacle detection module can plan a safe path based on the obstacle's location and then send the path parameters to the path prompt control circuit. The path prompt control circuit then drives the laser marker to project safe path markings on the ground. The path prompt control circuit can also feed back the laser projection status of the laser marker to the data analysis and processing circuit of the obstacle detection module to help it correct the reversing path, ensuring that obstacle judgment and path guidance always match the real-time scenario. Through the connection and collaboration of the above modules, real-time risk warnings and clear safe operation guidance can be provided to the driver, reducing the risk of collisions during reversing and improving operational safety and convenience.
[0053] When the position of the alarm needs to be fixed, firstly, rotating the rotating block 7 causes the threaded shaft 8 to rotate threadedly inside the fixed block 5. The threaded rotation of the threaded shaft 8 causes the connecting plate 9 to slide up and down on the inner wall of the sliding groove 14. Then, the sliding of the connecting plate 9 causes the spring 10 to be compressed. The spring 10 then causes the sliding block 11 to slide on the inner wall of the sliding groove 14. The sliding of the sliding block 11 causes the first ball 12 to squeeze the second ball 13, squeezing part of the second ball 13 from inside the fixed block 5 into the clamping block 4, thereby achieving the function of fixing and engaging the clamping block 4. At the same time, the clamping block 4 fixes the position of the sound and light alarm module 6. Similarly, through the rotation of the threaded shaft 8 and the rotation and squeezing of the first ball 12 and the second ball 13, the clamping block 4 can be easily removed, achieving the effect of disassembling and replacing the alarm installed in the sound and light alarm module 6.
[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
