[0013] Optionally, the wireless communicator includes a wireless communication body and a shielding shell.

[0014] Another objective of this invention is to provide a logistics vehicle equipped with an onboard wireless vibration signal transmission device that can monitor the vehicle's operating status, thereby ensuring the continuity and efficiency of the production process.
[0015] Based on the above concept, the technical solution adopted by this utility model is as follows:
[0016] A logistics vehicle is provided, including a vehicle body structure and the aforementioned vehicle-mounted wireless vibration signal transmission device. The vehicle body structure includes a vehicle body component and wheel components. The wheel components are used to drive the vehicle body component to move along the track of the logistics vehicle.

[0020] Optionally, the logistics vehicle further includes a distance sensor, which is disposed on the vehicle body component and is used to detect the distance between two adjacent logistics vehicles on the track.
[0021] The beneficial effects of this utility model are as follows:
[0022] This invention proposes a vehicle-mounted wireless vibration signal transmission device, comprising a vibration sensor, a power supply, and a wireless communicator. The vibration sensor includes a housing, an electrode assembly, and a buffer solution. The housing has a cavity, and both the electrode assembly and the buffer solution are located within the cavity, with the electrode assembly floating above the buffer solution. The electrode assembly is used to acquire vibration signals. The buffer solution not only provides temperature compensation for the electrode assembly within the cavity, ensuring the sealing temperature deviation of the vibration sensor remains stable within 5°C and guaranteeing the accuracy of vibration signal acquisition under different ambient temperatures, but also reduces noise from the smooth operation of the logistics vehicle, improving the accuracy of vibration signal acquisition. The power supply is located within the housing and mounted on the electrode assembly, providing power to ensure its normal operation. The wireless communicator is mounted on the housing and electrically connected to the electrode assembly. The vibration signal acquired by the electrode assembly is transmitted to the wireless communicator via a communication line, and then transmitted to the central controller of the logistics system. This allows staff to promptly obtain the vibration signal from the logistics vehicle. Upon receiving an abnormal vibration signal, the system can automatically stop the logistics vehicle's operation or manually stop it for timely maintenance. This vehicle-mounted wireless vibration signal transmission device integrates a vibration sensor, power supply, and wireless communicator into a single structural component, which is installed on the assembly cover of the logistics vehicle. This enables real-time monitoring of the logistics vehicle's operating status, thereby ensuring the continuity and efficiency of the production process.
[0023] The logistics vehicle proposed in this utility model includes a main body structure and the aforementioned vehicle-mounted wireless vibration signal transmission device. The main body structure includes a body component and wheel components. The wheel components drive the body component to move along the logistics vehicle's track. The vehicle-mounted wireless vibration signal transmission device is mounted on the body component. The logistics vehicle's track is laid along the path the logistics vehicle needs to travel, and the logistics vehicle moves along the track to transport goods to various locations along the path. Mounting the vehicle-mounted wireless vibration signal transmission device on the body component, compared to mounting it on the wheel component, avoids the vibration sensor acquiring invalid vibration signals. This is because the wheel component moves directly on the track, receiving more noticeable vibrations, while the body component often absorbs additional vibrations. These additional vibrations often do not affect the normal operation of the logistics vehicle and are not the vibration signals that the vehicle-mounted wireless vibration signal transmission device is intended to detect. The vehicle-mounted wireless vibration signal transmission device in this logistics vehicle enables monitoring of the logistics vehicle's operating status, ensuring the continuity and efficiency of the production process.

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0034] like Figure 1 As shown, this embodiment provides a vehicle-mounted wireless vibration signal transmission device 10, which includes a vibration sensor 1, a power supply 2, and a wireless communicator 3. The vibration sensor 1, the power supply 2, and the wireless communicator 3 are integrated into a single structural component and installed on the assembly cover 202 of the logistics vehicle, thereby enabling real-time monitoring of the logistics vehicle's operating status and ensuring the continuity and efficiency of the production process.
[0035] Specifically, the vibration sensor 1 includes a housing 15, an electrode assembly, and a buffer solution 14. The housing 15 has a cavity, and both the electrode assembly and the buffer solution 14 are located within the cavity, with the electrode assembly floating above the buffer solution 14. The electrode assembly is used to acquire vibration signals. The buffer solution 14 not only provides temperature compensation for the electrode assembly located within the cavity, ensuring that the sealing temperature deviation of the vibration sensor 1 remains stable within 5°C and guaranteeing the accuracy of vibration signal acquisition under different ambient temperatures, but also reduces the noise from the smooth operation of the logistics vehicle, improving the accuracy of vibration signal acquisition. Additionally, a power supply 2 is located within the housing 15 and mounted on the electrode assembly, providing power to the electrode assembly to ensure its normal operation. The wireless communicator 3 is installed on the housing 15 and is electrically connected to the electrode assembly. The vibration signal acquired by the electrode assembly is transmitted to the wireless communicator 3 through the communication line and then transmitted to the main controller of the logistics system through the wireless communicator 3. This allows staff to obtain the vibration signal of the logistics vehicle in a timely manner. Upon obtaining an abnormal vibration signal, staff can set the automatic stop of the logistics vehicle or manually stop the logistics vehicle to ensure timely maintenance of the logistics vehicle.
[0036] Optionally, to reduce the swaying of the power supply 2 within the housing 15, a power supply bracket 16 is also provided inside the housing 15. The power supply bracket 16 has a ring structure, and the power supply 2 is inserted into the inner ring of the ring structure. The ring structure is used to limit the swaying range of the power supply 2 in the direction perpendicular to its own length. In this embodiment, the outer wall of the ring structure is fixed to the inner wall of the air, while the inner ring of the ring structure is slightly larger than the outer circumference of the power supply 2, thereby ensuring that the power supply 2 can be inserted into the inner ring.
[0037] Optionally, the housing 15 includes an upper housing and a lower housing. The upper housing has an upper cavity, and the lower housing has a lower cavity, which are connected. In this embodiment, the upper and lower housings are detachably connected. The buffer solution 14 is first placed in the lower cavity, then the electrode assembly and power supply 2 are floated on the buffer solution 14, and the upper housing is then fastened to the opening of the lower housing, with the power supply 2 inserted into the inner ring of the annular structure. The upper and lower housings can be threaded together, with an external thread on the outer wall of the opening of the lower housing and a matching internal thread on the inner wall of the connection point. A sealing ring is provided at the assembly point to ensure a tight seal and prevent leakage of the buffer solution 14. In specific implementations, the lower cavity has a larger volume, the upper cavity has a smaller volume, and a stepped surface is formed at the connection point. The electrode assembly is located in the lower cavity, the power supply 2 is mounted on the electrode assembly and extends into the upper cavity, and the power supply bracket 16 is located in the upper cavity.
[0038] Optionally, the electrode assembly includes an upper electrode 11, a middle electrode 12, and a lower electrode 13. The middle electrode 12 is movable between the upper electrode 11 and the lower electrode 13 to increase the capacitance of the upper electrode 11 and decrease the capacitance of the lower electrode 13, or to decrease the capacitance of the upper electrode 11 and increase the capacitance of the lower electrode 13. The upper electrode 11 and the lower electrode 13 form the two plates of a capacitor. When the vibration sensor 1 is vibrated, the distance or relative area between the two electrodes changes, resulting in a change in capacitance. This change in capacitance can be detected and converted into a vibration signal. In a capacitive sensor with a differential structure, the middle electrode 12 serves as a movable plate. The upper and lower fixed plates and the middle movable plate form a differential capacitor structure. When the middle electrode 12 moves, the capacitance values of the upper and lower capacitors change differentially, which can improve the sensitivity of the vibration sensor 1.
[0039] Furthermore, in this embodiment, the wireless communicator 3 includes a wireless communication main body and a shielding shell. The wireless communication main body has a signal processing circuit, which is mainly responsible for processing received and transmitted signals. The signal processing circuit includes a low-noise operational amplifier, which can amplify the received signal and reduce noise interference, ensuring high-quality signal transmission and processing. The wireless communicator 3 supports multiple communication protocols, such as Bluetooth 5.0, Wi-Fi 6, or 5G, to meet the transmission distance and bandwidth requirements of different practical applications.
[0040] In this embodiment, the wireless communicator 3 is optimized for collecting different vibration data under different environments. It not only adopts synchronous sampling technology to ensure the consistency of sensor data timing while maintaining 5G network connectivity, but also sets a shielded shell on the outside of the wireless communication body and sets a shielding coating on the inner wall of the cavity of the vibration sensor 1's housing 15, thereby effectively isolating external electromagnetic radiation. This enables the vehicle-mounted wireless vibration signal transmission device 10 to detect and dynamically transmit the vibration of the logistics vehicle in real time, while ensuring second-level latency and high bandwidth transmission capabilities to meet the requirements of dynamic vibration monitoring.
[0041] like Figure 2As shown, this embodiment also provides a logistics vehicle, including a main body structure and the aforementioned vehicle-mounted wireless vibration signal transmission device 10. The main body structure includes a body component 20 and wheel components 30. The wheel components 30 are used to drive the body component 20 to move along the logistics vehicle's track 40. The vehicle-mounted wireless vibration signal transmission device 10 is disposed on the body component 20. The logistics vehicle's track 40 is laid along the path the logistics vehicle needs to run, and the logistics vehicle moves on the track 40 to transport goods to various locations along the path. Disposing the vehicle-mounted wireless vibration signal transmission device 10 on the body component 20, compared to disposing it on the wheel component 30, avoids the vibration sensor 1 acquiring invalid vibration signals. This is because the wheel component 30 moves directly on the track 40, and the vibration it receives is more obvious, while the body component 20 often absorbs some of the vibration. This part of the vibration often does not affect the normal operation of the logistics vehicle and is not the vibration signal that the vehicle-mounted wireless vibration signal transmission device 10 is trying to detect. The vehicle-mounted wireless vibration signal transmission device 10 provided in this embodiment can monitor the operating status of the logistics vehicle, ensuring the continuity and efficiency of the production process.
[0042] Optionally, the vehicle body component 20 includes a support assembly, a conveying assembly, and an assembly cover 202. The conveying assembly and the assembly cover 202 are disposed above the support assembly. The vehicle-mounted wireless vibration signal transmission device 10 is disposed on the assembly cover 202. The conveying assembly has a conveyor chain 201 that can move along the vertical direction of movement of the logistics vehicle. The wheel component 30 is disposed below the support assembly. The assembly cover 202 is a shell covering the support assembly. The support assembly includes two sets of supports arranged opposite each other in the direction of extension of the vertical track 40. Both ends of the assembly cover 202 are connected to the two sets of support assemblies, providing sufficient installation space for the vehicle-mounted wireless vibration signal transmission device 10. In addition, in specific implementations, the logistics vehicle provided in this embodiment can not only move along the extension direction of the support assembly, i.e., the track 40, but also, after the logistics vehicle has moved into place, push goods from the logistics vehicle to a designated position along the extension direction of the conveyor chain 201, or push goods at a designated position to the logistics vehicle via the conveyor chain 201.
[0043] Optionally, the conveying assembly includes a conveying bracket and a drive wheel assembly. The drive wheel assembly is rotatably mounted on the conveying bracket, and the conveying chain 201 is driven to move along the extension direction of the conveying bracket. The extension direction of the conveying bracket is perpendicular to the extension directions of the support assembly and the track 40. In a specific implementation, the conveying chain 201 and the drive wheel assembly constitute a chain drive structure. The drive wheel assembly includes at least one driving wheel and one driven wheel. The conveying chain 201 is sleeved on the outer periphery of the driving wheel and the driven wheel. When the driving wheel is driven to rotate by the first motor of the logistics vehicle, it can drive the driven wheel to rotate through the conveying chain 201, thereby realizing the movement of the conveying chain 201 along the extension direction of the conveying bracket.
[0044] Optionally, the logistics vehicle also includes guide indicator lights, which are mounted on the vehicle body component 20. These guide indicator lights indicate the conveying direction of the conveyor chain 201 and / or the movement direction of the logistics vehicle. In a specific implementation, the guide indicator lights are electrically connected to the logistics vehicle's controller so that the guide indicator lights can activate different modes according to the operating status of the logistics vehicle.
[0045] In this embodiment, the guide indicator light can be a transmission indicator light. When the transmission chain 201 rotates in the forward direction, the transmission indicator light displays the first color, and when the transmission chain 201 rotates in the reverse direction, the transmission indicator light displays the second color. The forward and reverse rotation of the transmission chain 201 changes with the forward and reverse rotation of the first motor. That is, when the first motor rotates forward, it synchronously drives the transmission wheel set to rotate forward, causing the transmission chain 201 to rotate forward; conversely, when the first motor rotates in reverse, it synchronously drives the transmission wheel set to rotate in reverse, causing the transmission chain 201 to rotate in reverse. Here, forward and reverse rotation refer to two opposite clockwise directions, used only as an example. When the transmission wheel set rotates in the opposite direction, the transmission direction of the transmission chain 201 will be reversed.
[0046] In this embodiment, the guide indicator can be a movement indicator, meaning that the movement indicator displays one color when the logistics vehicle moves forward and another color when it moves backward. The movement of the logistics vehicle originates from the wheel component 30, which includes wheels and a second motor. The wheels are rotatably mounted on a support assembly. The second motor controls the rotation of the wheels; that is, controlling the wheels to rotate clockwise moves the logistics vehicle forward, and controlling the wheels to rotate counterclockwise moves the logistics vehicle backward. Here, clockwise and counterclockwise rotation are two opposite clockwise directions, used only as an example. When the wheels rotate in opposite directions, the movement direction of the logistics vehicle will be reversed.
[0047] Optionally, the logistics vehicle also includes a distance sensor 203, which is mounted on the vehicle body component 20. The distance sensor 203 is used to detect the distance between two adjacent logistics vehicles on the track 40. In specific implementations, multiple logistics vehicles move on the track 40 to achieve large-scale transportation of goods. By setting the distance sensor 203 to monitor the distance between two adjacent logistics vehicles in real time, collisions between adjacent logistics vehicles caused by the malfunction of one logistics vehicle can be avoided. In specific implementations, the distance sensor 203 can be an infrared sensor.
[0048] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
