Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of compact vehicle parts, specifically to a compact vehicle heater that is easy to assemble. Background Technology
[0002] In recent years, the country has vigorously promoted green and low-carbon technology innovation and encouraged green, low-carbon, and circular development, resulting in the rapid development and widespread adoption of environmentally friendly compact cars. However, as people's demands for driving comfort continue to rise, existing compact vehicles, lacking a central heating system, fail to provide a comfortable driving environment in cold winters, leading to some complaints about their driving comfort. To add a central heating system to compact vehicles, some manufacturers have attempted to adapt existing automotive air conditioning systems for use in electric vehicles. However, the energy consumption and specific installation design requirements of existing automotive air conditioning systems make them unsuitable for installation in the space-constrained, enclosed compact vehicles. Furthermore, heating equipment installed in compact vehicles often needs to be miniaturized, typically requiring welding or threaded fastening during assembly, which makes installation and removal inconvenient. Utility Model Content
[0003] The purpose of this invention is to provide a compact vehicle heater that is easy to assemble, thereby solving the problems of difficulty in heating compact vehicles and difficulty in assembling heating equipment.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a compact vehicle heater that is easy to assemble, comprising a mounting bracket, a fan, and a PTC heating element. The mounting bracket includes a fan mounting frame and a PTC mounting box. The fan mounting frame includes a top plate with a fan inlet in the middle. The fan is mounted on the top plate and located above the fan inlet. The PTC mounting box is fixedly connected to the front end of the top plate. The front side of the PTC mounting box has an air guide port, and the rear side of the PTC mounting box has an opening. Multiple arrayed PTC heating elements are arranged inside the PTC mounting box. The fan outlet is correspondingly fitted to the rear side of the PTC mounting box. A fan housing is detachably connected to the fan mounting bracket and covers the fan. The front end of the fan housing is open, and the front end of the fan housing fits tightly against the rear end of the PTC mounting box.
[0005] The aforementioned technical solution features a simple structure, small size, low power consumption, and easy installation in compact vehicles. This compact heater is suitable for the interior of compact vehicles with limited driving space, providing a warmer driving environment during the cold winter season while also facilitating the installation and removal of the heater's interior.
[0006] The present invention is further configured to include a limiting plate and a first locking strip. The limiting plate includes a vertical plate and a horizontal plate. The vertical plate is fixedly connected to the upper end of the top plate, and the horizontal plate is fixedly connected to the upper end of the vertical plate. The limiting plate and the top plate together form a locking groove. The first locking strip is set along the lower end of the side outer wall of the fan housing, and the first locking strip is adapted to be inserted into the locking groove.
[0007] By adopting the above technical solution and utilizing the slot structure to achieve a detachable connection, rapid assembly and disassembly can be realized. The assembly and disassembly process usually does not require auxiliary tools, which can greatly simplify the assembly process and improve efficiency.
[0008] The present invention is further configured to include a fixing block and a through hole, the through hole being disposed on the top plate, the fixing block being fixedly connected to the lower end of the fan housing, and the fixing block being adapted to be inserted into the through hole.
[0009] By adopting the above technical solution, a fixing block is inserted into the through hole to prevent the fan casing from moving horizontally due to external forces.
[0010] The present invention is further configured to include a guide groove, which is disposed at the rear end of the top plate and located directly behind the through hole.
[0011] By adopting the above technical solution, not only can the fixing block be guided to move in the positive direction of the through hole, but the deformation rate caused by the pressing of the fixing block with the top plate during movement can also be reduced, preventing damage caused by the instantaneous deformation of the fixing block.
[0012] The present invention is further configured to include a sleeve, which is disposed at the lower end of the fan housing. The inner wall of the sleeve is provided with a plurality of second retaining strips spaced apart along the circumferential direction. The fan includes an impeller and a motor. The impeller is a cylindrical shape with an open upper end. The motor is disposed inside the upper port of the impeller and is sleeved inside the sleeve. The upper end of the motor is provided with a limiting block distributed along the diameter direction, and the two ends of the limiting block abut against the adjacent second retaining strips.
[0013] By adopting the above technical solution, the motor will generate vibration when it is running, or the impeller will generate a reaction force on the motor when it rotates. The limit block is pressed between the second locking strip to prevent the motor from shifting or the vibration from being transmitted to other components and causing damage.
[0014] The present invention is further configured to include hooks, wherein the lower end of the sleeve has two notches, and the two hooks are disposed in the notches.
[0015] By adopting the above technical solution, the notch design allows the lower end of the sleeve to generate a certain tension when the motor is fitted into the sleeve, making it easier to accommodate the motor. The hook plays the role of limiting the position of the motor, ensuring that the limiting block is always at the same horizontal level as the second locking strip.
[0016] The present invention is further configured such that a backup storage box is fixedly connected below the top plate, and a PLC board is provided inside the backup storage box. The backup storage box is an optional accessory, which can be detached and installed below the top plate by bolts. If control is used from below the PLC board, the PLC board can be placed inside the backup storage box. If control is not used from the PLC board and direct wire connection is used, the backup storage box does not need to be connected.
[0017] The present invention is further provided that thermally conductive silicone grease is provided between the PTC heating element and the PTC heating element.
[0018] By adopting the above technical solution, thermal grease fills the tiny gaps between PTC chips to form a uniform thermally conductive layer, thereby improving the speed and efficiency of heat transfer.
[0019] Furthermore, the fan mounting bracket is an n-shaped platform with two legs (left and right) and a top plate, and the PTC mounting box is a rectangular box. This shape and structure of the fan mounting bracket allows for a larger space between the left and right legs to facilitate ventilation.
[0020] Installing the heater of the above-mentioned technical solution in a compact vehicle can solve the problem of heating difficulties in existing compact vehicles. At the same time, the structure is simple and compact, making it more suitable for use in the cramped cab of a compact vehicle. Attached Figure Description
