Description

Technical Field

[0001] This utility model belongs to the field of weighing sensor technology, specifically relating to a vehicle-mounted weighing sensor device that is easy to install. Background Technology

[0002] The vehicle load sensor uses the change in height from the cargo box to the axle or wheels when the vehicle is empty and fully loaded as the effective range, and calculates the displacement distance of the sensor to convert it into the actual load weight of the vehicle.

[0003] Current vehicle-mounted load cells often face problems such as inconvenient installation and poor adaptability during vehicle installation. Due to differences in the structure and installation location of different vehicle models, traditional vehicle-mounted load cell devices are difficult to quickly adapt to different installation scenarios. Therefore, a vehicle-mounted load cell device that is easy to install is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle-mounted weighing sensor device that is more adaptable, stable, and easy to install in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An easy-to-install vehicle-mounted weighing sensor device includes a sensor body and a transmission line disposed on the sensor body. Rotating rods are rotatably disposed at both ends of the sensor body, and an upper mounting plate and a lower mounting plate are respectively disposed at both ends of the sensor body via the rotating rods.

[0007] It also includes:

[0008] A one-way rotation mechanism is provided at both ends of the sensor body. The sensor body is connected to the rotating rod through the one-way rotation mechanism, and the one-way rotation mechanism is arranged in a symmetrical manner.

[0009] As a further optimization of this utility model, the unidirectional rotation mechanism includes a mounting ring, which is fixedly mounted on the sensor body. A ratchet is provided on the rotating rod, and a pawl is rotatably mounted on the sensor body. An elastic element is provided between the pawl and the mounting ring.

[0010] As a further optimization of this utility model, the upper mounting plate is a C-shaped plate, an extension plate is provided at one end of the upper mounting plate, and sliding grooves are provided at both ends of the upper mounting plate.

[0011] As a further optimization of this utility model, the lower mounting plate is an L-shaped plate, and a connecting seat is provided on the lower mounting plate.

[0012] As a further optimization of this utility model, both the upper mounting plate and the connecting seat are provided with bolts, and the upper mounting plate and the connecting seat are rotatably connected to the rotating rod by bolts.

[0013] As a further optimization of this utility model, the rotating rod is sleeved on the bolt, and a limiting sleeve is sleeved on the rotating rod, with the limiting sleeve located on both sides of the rotating rod.

[0014] As a further optimization of this utility model, the bolt is installed on the upper mounting plate through a groove.

[0015] As a further optimization of this utility model, a nut is provided on the bolt, and the bolt is fixedly mounted on the upper mounting plate and the connecting seat by the nut.

[0016] The beneficial effects of this utility model are as follows:

[0017] Unlike existing technologies, in actual use, the sensor body is connected to the upper and lower mounting plates via a rotatable rotating rod. This makes the selection of the sensor body's installation position more flexible and adaptable. At the same time, the rotating rod is connected to both ends of the sensor body via a one-way rotating mechanism, so that the rotating rod can only rotate in one direction. After installation, the symmetrically arranged one-way rotating mechanism ensures that both ends of the sensor body can only rotate in opposite directions. This effectively fixes the angle of the sensor body and prevents the sensor body from deflecting and the transmission line angle from changing due to vehicle vibration. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1 - Figure 3 As shown, an easy-to-install vehicle-mounted weighing sensor device includes a sensor body 1 and a transmission line 11 mounted on the sensor body 1. Rotating rods 6 are rotatably mounted at both ends of the sensor body 1. An upper mounting plate 2 and a lower mounting plate 3 are respectively mounted at both ends of the sensor body 1 via the rotating rods 6. The upper mounting plate 2 is a C-shaped plate with an extension plate 22 at one end and sliding grooves 21 at both ends. The lower mounting plate 3 is an L-shaped plate with a connecting seat 31. This structural design allows the C-shaped plate of the upper mounting plate 2 to cooperate with the extension plate 22, adapting to various complex vehicle roof mounting environments. The relative position with the rotating rods 6 can be flexibly adjusted via the sliding grooves 21. The L-shaped plate of the lower mounting plate 3, combined with the connecting seat 31, can be stably installed at different positions on the bottom of the vehicle, greatly improving the sensor device's adaptability to different vehicle models and installation positions, reducing installation difficulty, and minimizing installation time and effort.

[0025] The sensor body 1 is equipped with a one-way rotation mechanism 7 at both ends. The sensor body 1 is connected to the rotating rod 6 through the one-way rotation mechanism 7. The one-way rotation mechanism 7 is arranged in a symmetrical form. The one-way rotation mechanism 7 includes a mounting ring 71, which is fixedly mounted on the sensor body 1. A ratchet 72 is provided on the rotating rod 6, and a pawl 73 is rotatably mounted on the sensor body 1. An elastic element 74 is provided between the pawl 73 and the mounting ring 71. Through the clever cooperation of the mounting ring 71, ratchet 72, pawl 73 and elastic element 74, the symmetrical one-way rotation mechanism 7 allows the rotating rod 6 to flexibly adjust its angle according to actual needs during installation. After installation, the symmetrical one-way rotation characteristic can effectively lock the angle of the sensor body 1, that is, the two ends of the sensor body 1 can rotate in opposite directions. This prevents the sensor body 1 from deflecting even if the vehicle encounters severe vibration during driving, thereby avoiding problems such as displacement and pulling of the transmission line 11 due to sensor position changes. This ensures the accuracy and stability of the sensor's data transmission and extends the sensor's service life.

[0026] Both the upper mounting plate 2 and the connecting seat 31 are perforated with bolts 4. The upper mounting plate 2 and the connecting seat 31 are rotatably connected to the rotating rod 6 via bolts 4. The rotating rod 6 is sleeved on the bolts 4, and a limiting sleeve 5 is sleeved on the rotating rod 6. The limiting sleeve 5 is located on both sides of the rotating rod 6. The bolts 4 are perforated on the upper mounting plate 2 via grooves 21, and nuts are provided on the bolts 4. The bolts 4 are fixed to the upper mounting plate 2 and the connecting seat 31 by the nuts. The combination design of bolts 4, nuts, limiting sleeves 5, upper mounting plate 2, and connecting seat 31 not only realizes the rotatable connection between the upper mounting plate 2, lower mounting plate 3, and rotating rod 6, which makes it convenient for installers to accurately adjust the installation angle according to the actual situation during installation, but also, after adjustment, it is fixed by tightening the nuts. The limiting sleeves 5 can further restrict the position of the rotating rod 6 to prevent it from loosening or shifting during vehicle operation, ensuring the stability of the entire sensor device installation. At the same time, this connection method is easy to disassemble and maintain, improving the practicality and economy of the device.

[0027] It should be noted that the working principle of this vehicle-mounted weighing sensor device is as follows: The sensor body 1 is connected to a rotating rod 6 at both ends via a one-way rotating mechanism 7. The mounting ring 71 in the one-way rotating mechanism 7 is fixed to the sensor body 1. A ratchet 72 is provided on the rotating rod 6. An elastic element 74 between the pawl 73 rotatably mounted on the sensor body 1 and the mounting ring 71 ensures that the rotating rod 6 can only rotate in one direction. The rotating rod 6 is connected to an upper mounting plate 2 and a lower mounting plate 3 at both ends. The upper mounting plate 2 is a C-shaped plate with an extension plate 22 at one end and sliding grooves 21 at both ends. The lower mounting plate 3 is an L-shaped plate with a connecting seat 31. Bolts 4 pass through the sliding grooves 21 of the upper mounting plate 2 and the rotating rod 6, fixing the upper mounting plate 2 to the upper end of the sensor body 1 with nuts. Bolts 4 pass through the lower mounting plate 3, fixing the lower end of the sensor body 1 to the sensor body 1. The rotating rod 6 is fitted onto the bolts 4, and limiting sleeves 5 are provided on both sides to restrict the position of the rotating rod 6. During installation, the angles of the upper mounting plate 2 and the lower mounting plate 3 can be adjusted by rotating the rod 6. Based on the actual usage, the upper mounting plate 2 and the lower mounting plate 3 can be welded and fixed in different positions on different vehicle models. After installation, the angle of the sensor body 1 is fixed by the symmetrically arranged one-way rotation mechanism 7 to prevent the sensor body 1 from deflecting due to vehicle vibration, which would cause the position of the transmission line 11 to change, thus achieving convenient and stable installation of the sensor.

[0028] The embodiments described above are merely examples 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 this 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 modifications and improvements all fall within the protection scope of this utility model.
