Description

Technical Field

[0001] This utility model relates to the field of engine parts technology, and in particular to a protective device. Background Technology

[0002] The diesel heater is an independent onboard heating device separate from the car engine, with its own fuel lines, electrical circuits, combustion heating components, and control systems. It preheats the engine and passenger compartment of a car parked in cold winter conditions without requiring the engine to be started. The diesel heater is a key component ensuring normal operation in low-temperature environments, completely eliminating cold-start wear in vehicles.

[0003] While existing diesel heater protective devices effectively prevent dust from entering the heater, they present some inconveniences for maintenance. When maintenance is required, the existing protective device, being a single unit, must be completely disassembled to access the internal heater and related components (such as solenoid valves and fuel pumps). This design not only increases the workload for maintenance personnel but also risks damage to the protective device due to frequent disassembly and reassembly. Furthermore, the need to disassemble the entire protective device for each maintenance visit undoubtedly consumes significant time and manpower, reducing maintenance efficiency. Especially in emergencies, this inconvenience can delay problem-solving. Additionally, frequent disassembly and reassembly may cause loosening or wear of connecting pipes, solenoid valves, and other components, thereby affecting the overall performance of the diesel heater.

[0033] This utility model provides a protective device, including a mounting frame 1 and a protective cover 2. The protective cover 2 and the mounting frame 1 form an installation space for a diesel heater 14. The mounting frame 1 is connected to the vehicle frame and is provided with a mounting base 101. The diesel heater 14 is connected to the mounting base through a fastener 11. The protective cover 2 includes a protective baffle 21 and a cover 22. The protective baffle 21 includes at least two side baffles. The side baffles are connected to the mounting frame 1, and the cover 22 is connected to at least one side baffle.

[0034] like Figures 1-6As shown, the protective device provided by this utility model forms the installation space for the diesel heater 14 by setting up the mounting bracket 1 and the protective cover 2. By installing the diesel heater 14 in the protective device, it can prevent external objects from directly contacting the diesel heater 14, reducing the risk of damage to the diesel heater 14 due to collision or accidental contact. In addition, the protective device can protect the diesel heater 14, ensuring that it is not exposed to the outside world and dust accumulation occurs. Furthermore, the installation space formed by the protective cover 2 and the mounting bracket 1 of this utility model is compactly designed, reducing the occupation of the vehicle's interior space and making the vehicle design more flexible.

[0035] In one embodiment of this utility model, the protective baffle 21 consists of two side baffles, one of which is a first side baffle 211 and the other is a second side baffle 212, as shown below. Figure 1-Figure 4 As shown, the first side baffle 211 is a bent plate, and the second side baffle 212 is a U-shaped plate. The first side baffle 211 is connected to the mounting bracket 1, the second side baffle 212 and the cover 22 respectively. The second side baffle 212 is connected to the first side baffle 211, the mounting bracket 1 and the cover 22 respectively. The first side baffle 211 is provided with an inspection port 3. The cover 22 is provided with a water inlet 7 and a water outlet 8. The water inlet 7 and the water outlet 8 are provided with mounting parts 9. The mounting base 101 is provided with a smoke exhaust port 6.

[0036] Since the diesel heater 14 has its own fuel lines, circuits, combustion heating devices, and control devices, when the diesel heater 14 requires maintenance, the protective baffle 21 can be configured as multiple side baffles to facilitate maintenance personnel to inspect and repair various components of the diesel heater 14. In a preferred embodiment, the inspection port 3 of the first side baffle 211 is located in the solenoid valve and wiring harness connection area of ​​the diesel heater 14. When the diesel heater 14 malfunctions, the solenoid valve or wiring harness of the diesel heater 14 can be inspected and repaired through the inspection port 3. If the solenoid valve or wiring harness of the diesel heater 14 malfunctions, maintenance personnel can repair or replace the faulty unit of the diesel heater 14 simply by removing the first side baffle 211. When the diesel heater 14 as a whole needs maintenance or replacement, maintenance personnel only need to remove the second side baffle 212 and the cover 22 to access the diesel heater. 14 Overall maintenance; The vehicle has an inlet pipe and an outlet pipe connected to the diesel heater 14. To facilitate the connection between the inlet pipe and the outlet pipe and the diesel heater 14, an inlet pipe 7 and an outlet pipe 8 are provided on the cover 22. The inlet pipe is connected to the inlet end of the diesel heater 14 through the inlet pipe 7, and the outlet pipe is connected to the outlet end of the diesel heater 14 through the outlet pipe 8. The mounting part 9 is used to fix the inlet pipe, outlet pipe and protective device. When the connection position of the inlet pipe and outlet pipe of the diesel heater 14 malfunctions and needs to be repaired, the maintenance personnel only need to remove the cover 22 to repair the connection position of the inlet pipe and outlet pipe.

[0037] By setting the protective baffle 21 into multiple side baffles, it is convenient for maintenance personnel to inspect and repair various components of the diesel heater 14. The disassembly is simple, reducing the disassembly and assembly time of the protective device, thereby shortening the maintenance time of the diesel heater 14 and improving maintenance efficiency. At the same time, it avoids problems such as loosening or wear of connecting pipes, solenoid valves and other parts of the diesel heater 14 due to frequent disassembly and assembly.

[0038] It should be noted that this utility model does not limit the type of mounting component 9. In one embodiment, the mounting component 9 is a clamp.

[0039] Furthermore, such as Figure 4 As shown, in one embodiment of the protective device of this utility model, the mounting bracket 1 is L-shaped, and the end of the mounting bracket 1 away from the mounting seat 101 is connected to the vehicle frame. The side of the mounting bracket 1 away from the diesel heater 14 is provided with reinforcing ribs 4. The protective device also includes an auxiliary mounting bracket 10, which is L-shaped. One end of the auxiliary mounting bracket 10 is connected to the mounting bracket 1 and / or the protective baffle 21, and the other end of the auxiliary mounting bracket 10 is connected to the vehicle frame.

[0040] Mounting bracket 1 is L-shaped, with its vertical side plate resting against the longitudinal beam of the vehicle frame. The transverse side plate of mounting bracket 1 serves as mounting seat 101, on which the diesel heater 14 is mounted. By arranging mounting bracket 1 in an L-shape, the installation space formed by the protective cover 2 and mounting bracket 1 becomes more compact, allowing the diesel heater 14 to better fit the vehicle frame and reducing its impact on the vehicle's interior space. One end of auxiliary mounting bracket 10 is connected to mounting bracket 1 or protective baffle 21. Auxiliary mounting bracket 10 is positioned opposite mounting bracket 1, thus forming a U-shape with mounting bracket 1. The diesel heater 14 is installed between auxiliary mounting bracket 10 and mounting bracket 1. Furthermore, reinforcing ribs 4 are present on the sides of mounting bracket 1 and mounting seat 101 away from the diesel heater 14. The inclusion of reinforcing ribs 4 and auxiliary mounting bracket 10 increases the overall strength of the protective device, enhances the structural stability of the entire device, and improves the stability of the connection between the diesel heater 14 and the vehicle frame.

[0041] In a preferred embodiment, the fixing member 11 includes a positioning bolt 110 and a buffer body 111. The mounting base 101 is provided with a mounting hole. The buffer body 111 is located between the diesel heater 14 and the mounting base 101, and the buffer body 111 abuts against the diesel heater 14 and the mounting base 101. The positioning bolt 110 passes through the diesel heater 14, the buffer body 111 and is connected to the mounting base 101.

[0042] like Figure 5 , Figure 6 As shown, in this embodiment, when the construction personnel install the diesel heater 14 on the mounting base 101, only the positioning bolt 110 can be used to pass through the diesel heater 14, the buffer body 111 and the mounting base 101 to connect. Through the combination of the mounting base 101 and the fixing member 11, the installation of the diesel heater 14 becomes simple and quick, reducing the installation difficulty. In addition, since the buffer body 111 is set between the diesel heater 14 and the mounting base 101, the impact of vehicle vibration on the diesel heater 14 can be reduced, and the working stability of the diesel heater 14 is improved.

[0043] It should be noted that the present invention does not limit the buffer body 111. In one embodiment, the buffer body 111 is a spring.

[0044] In a preferred embodiment, the protective baffle 21 is provided with an air inlet 12, which is located at the air inlet of the diesel heater 14; a filter element 13 is provided on the outer side of the air inlet 12 away from the diesel heater 14, and the filter element 13 is fixedly connected to the protective baffle 21.

[0045] like Figure 4As shown, in one embodiment of this utility model, the protective baffle 21 of the protective device is provided with an air inlet 12. This air inlet 12 is located at the air inlet of the diesel heater 14, ensuring that air can smoothly enter the diesel heater 14, meeting its oxygen supply requirements for operation and thus improving combustion efficiency. Furthermore, good gas flow helps to remove the heat generated by the diesel heater 14, preventing overheating and extending its service life. Additionally, the filter element 13 effectively blocks dust and particulate matter in the air, preventing these impurities from entering the diesel heater 14, reducing dust accumulation on the heater, keeping the diesel heater 14 clean, reducing the failure rate caused by blockage or wear, and improving its operational reliability and stability. The filter element 13 is installed on the outside of the protective baffle 21, allowing personnel to easily clean and replace it regularly without disassembling the entire protective device, simplifying the maintenance process.

[0046] It should be noted that this utility model does not limit the form of the filter element 13. In one embodiment, the filter element 13 is a filter screen.

[0047] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
