Description

Technical Field

[0001] This utility model relates to the field of special equipment performance testing technology, specifically to an integrated field vehicle braking performance testing device. Background Technology

[0002] Special-purpose motor vehicles used in factories and plant areas (hereinafter referred to as "factory vehicles") are one of the eight categories of special equipment. The braking performance of these vehicles directly affects driving and operational safety and is also an important indicator of active safety. During operation, factory vehicles should be able to ideally achieve functions such as deceleration and stopping under the driver's control. Furthermore, the braking performance of factory vehicles is one of the mandatory inspection items stipulated in TSG81—2022 "Safety Technical Regulations for Special-Purpose Motor Vehicles Used in Factories and Plants".

[0003] The braking performance of parking vehicles mainly consists of two parts: parking brake and service brake. Parking brake refers to the resistance applied to the vehicle when it is parked, preventing it from rolling. Service brake refers to the driver's operation of the service brake system (such as foot brake or handbrake) during driving, slowing down and stopping as needed or stopping within the shortest distance, and maintaining a stable speed when driving downhill. Many factors affect the service braking distance of parking vehicles, but initial braking speed and braking force are two extremely important factors. Although current standards specify both initial braking speed and braking force, current testing devices, using braking distance as the measurement method, only consider the initial braking speed factor and do not simultaneously consider the influence of braking force. Therefore, the test results are flawed or obtained under unqualified conditions. Furthermore, current testing instruments have multiple installation positions, are cumbersome to operate, and have strict requirements for the testing site, limiting their use. Utility Model Content

[0004] Therefore, this utility model provides an integrated field vehicle braking performance testing device to solve at least one technical problem existing in the prior art.

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] In one specific implementation, such as Figure 1 and Figure 2 As shown, the integrated vehicle braking performance testing device provided by this utility model includes a main unit, a pressure sensor 8, and a handheld terminal. The main unit includes a housing, a circuit board 10 installed within the housing, and a magnetic suction assembly installed within the housing. The main unit is detachably mounted on the vehicle to be tested via the magnetic suction assembly. During use, the main unit is placed on the vehicle to be tested according to the direction indicated on the nameplate. The pressure sensor 8 is detachably mounted on the brake pedal 7 of the vehicle to be tested via a fixing assembly. The pressure sensor 8 is connected to the main control plug 5 of the main unit via a cable. The handheld terminal communicates with the main unit via Bluetooth. The handheld terminal can be used for data presentation, allowing test results to be displayed and recorded in real time, facilitating quick data acquisition and analysis by operators. It should be understood that the handheld terminal can be a tablet computer, a laptop computer, or a dedicated display device, etc.

[0026] In this way, the braking force can be collected by the pressure sensor 8 installed on the brake pedal 7, and the pressure sensor 8 is integrated with the main unit into a test device, solving the problem of multiple test stations required in the existing technology. The integrated design of the main unit makes the entire test device more compact, easy to carry and operate, and the magnetic component design allows the main unit to be quickly installed on the vehicle, improving test efficiency.

[0027] Specifically, the housing includes a housing base 2 and a housing cover 1 detachably connected to the housing base 2. The detachable housing cover 1 makes the installation and maintenance of the internal components of the main unit more convenient, improving the maintainability of the equipment. The detachable housing base 2 and housing cover 1 can be fixed together by screws or clips to improve the sealing and durability of the equipment.

[0028] The aforementioned magnetic assembly includes multiple strong magnets 11, which are evenly distributed on the bottom of the housing 2. For example, the main unit has three built-in strong magnets 11, each horizontally arranged on the bottom of the main unit's housing, which can be attracted to the forks. The even distribution of multiple strong magnets 11 increases the attraction between the main unit and the vehicle, ensuring that the main unit will not loosen or fall off during testing. The magnetic assembly can be replaced with other detachable installation methods, such as suction cups, hooks, or dedicated brackets, to adapt to different types of vehicles and installation requirements.

[0029] Specifically, the fixing component includes a fixing groove 13 and a strap. The fixing groove 13 is formed on the base of the pressure sensor 8, and the strap passes through the fixing groove 13 and is tied to the brake pedal 7. The combined design of the fixing groove 13 and the strap allows the pressure sensor 8 to be securely installed on the brake pedal, preventing the sensor from shifting due to vibration or impact during testing. Other fixing methods can be used for the fixing component, such as adhesive fasteners, snap-on fasteners, or special clamps, to adapt to brake pedals of different shapes and sizes.

[0030] The base has a flat surface facing the brake pedal 7, which makes it more suitable for fixing to the brake pedal 7. The flat structure of the base can better fit the brake pedal 7, reducing data errors caused by poor contact. The base can be designed as curved or other shapes to accommodate brake pedals of different shapes.

[0031] Furthermore, the main unit also includes an internal antenna interface 3, an external antenna interface 4, a main control plug 5, a switch 6, and a charging connector 12. A lithium battery 9 is installed inside the main unit, and a Bluetooth antenna can be connected via the external antenna interface 4. The main unit has a built-in circuit board 10, which integrates an accelerometer chip for measuring vehicle acceleration. The external antenna interface 4 allows the main unit to connect to an external antenna, enhancing signal transmission capabilities. The design of the switch 6 and charging connector 12 makes the main unit more convenient to use. The main unit can also be designed with an internal antenna to reduce the number of external interfaces and improve the device's waterproof and dustproof performance.

[0032] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solution of this utility model should be included within the scope of protection of this utility model.
