Description

Technical Field

[0001] This utility model relates to the field of inverter technology, specifically a three-camera vehicle air conditioning inverter. Background Technology

[0002] An air conditioning inverter is a device that converts direct current (DC) to alternating current (AC), primarily used in air conditioning systems. The inverter's role in an air conditioner is to respond to cooling demands by changing the compressor speed, thereby continuously adjusting the air conditioner's cooling and heating capabilities to ensure the room can be quickly cooled or heated to the desired temperature and maintained at a constant level. However, existing air conditioning inverters still experience some problems during actual use.

[0003] For example, application number CN202122313600.1 relates to an air conditioner inverter that is easy to wall-mount, including a main unit, absorbent cotton, a sealing plate, and an isolation plate fixedly connected to the main unit. The isolation plate and the sealing plate are fixedly connected and together form a cavity. The absorbent cotton is placed inside the cavity. The sealing plate has multiple perforations that lead to the cavity, which has the characteristics of avoiding corrosion and protecting the inverter from damage. Most existing inverters have relatively simple structures, and heat may accumulate during use, which reduces the working efficiency of the inverter and greatly affects the working efficiency of the device.

[0004] To address the aforementioned issues, a three-camera vehicle air conditioning inverter is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a three-camera vehicle air conditioning inverter. By using this device, the problem of existing inverters having a relatively simple structure and the potential for heat accumulation during use, which reduces the inverter's efficiency and greatly affects the device's working efficiency, is solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-camera vehicle air conditioning inverter, comprising an inverter body and a detachable protective cover mounted on the top of the inverter body. The inverter body is provided with a cooling mechanism, which ensures that the heat generated by the inverter body during operation can be dissipated in a timely manner. The cooling mechanism includes a ventilation window fixedly connected to one side of the inverter body, and a filter screen is detachably mounted on one side of the ventilation window. A limiting groove is also provided on the top of the inverter body, and a limiting rod is fixedly connected to the bottom of the protective cover.

[0007] Preferably, a fan module is installed inside the ventilation window, and the fan module is electrically connected to the power line of the inverter body. A placement slot is provided on one side of the ventilation window.

[0008] The design of the above structure, with the addition of a fan module, allows the heat generated by the inverter to be dissipated in a timely manner, making it convenient to use.

[0009] Preferably, a placement block is fixedly connected to the outer side of the filter screen, and multiple sets of placement slots and placement blocks are provided, with screws threaded onto the placement block.

[0010] The design of the above structure, with the placement blocks and slots, allows related devices to be connected, improving convenience.

[0011] Preferably, the inner side of the placement slot is provided with a threaded groove that matches the screw, and a pressing block is slidably connected to the other side of the inverter body.

[0012] The design of the above structure, with its threaded grooves and screws, makes it easier to install and remove the filter screen, thus improving convenience.

[0013] Preferably, a sliding block is fixedly connected to one side of the pressing block, a trapezoidal locking block is fixedly connected to the top of the sliding block, and a return spring is fixedly connected to one side of the sliding block.

[0014] The above-described structure, with the addition of a reset spring, enables the sliding block to automatically reset, thus improving its usability.

[0015] Preferably, one end of the reset spring is fixedly connected to the inside of the inverter body, and multiple sets of the limiting rod and the limiting groove are provided, with the limiting rod and the limiting groove slidingly engaged.

[0016] The design of the above structure, with the setting of limiting rods and limiting grooves, makes the installation process of the protective cover faster and improves work efficiency.

[0017] Preferably, a slot is provided on one side of the limiting rod, and the slot slides in cooperation with the trapezoidal block.

[0018] The design of the above structure, with its slots and trapezoidal blocks, ensures that the top cover of the inverter will not fall off during use.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This application achieves the function of removing internal heat from the inverter body during use by setting up a fan module, screws, ventilation windows and filters, thereby improving the performance and solving the problem that most existing inverters have relatively simple structures, which may cause heat accumulation during use, reducing the inverter's working efficiency and greatly affecting the device's working efficiency.

[0021] 2. This application, through the setting of pressing block, protective cover, limit rod and trapezoidal locking block, enables staff to easily open the protective cover and perform maintenance operations, thereby improving work efficiency. It also solves the problem that most existing air conditioning inverters are integrated structures, which makes it inconvenient for staff to perform maintenance operations when problems occur inside the inverter, thus affecting work efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0030] Combination Figure 1 , Figure 2 and Figure 4A three-camera vehicle air conditioning inverter includes an inverter body 1 and a detachable protective cover 2 on the top of the inverter body 1. The inverter body 1 is equipped with a cooling mechanism, which can ensure that the heat generated by the inverter body 1 during operation can be discharged in a timely manner. The cooling mechanism includes a ventilation window 11 fixedly connected to one side of the inverter body 1. A filter screen 12 is detachably installed on one side of the ventilation window 11. A limit groove 13 is also opened on the top of the inverter body 1. A limit rod 21 is fixedly connected to the bottom of the protective cover 2.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the issue that existing inverters often have a relatively simple structure, which can lead to heat buildup during use, reducing inverter efficiency and significantly impacting device performance, this embodiment discloses the following technical solution, specifically as follows: Figures 1-3 As shown, a fan module 111 is installed inside the ventilation window 11, and the fan module 111 is electrically connected to the power cord of the inverter body 1. A placement slot 112 is provided on one side of the ventilation window 11, and a placement block 121 is fixedly connected to the outside of the filter screen 12. Multiple sets of placement slots 112 and placement blocks 121 are provided. Screws 122 are threadedly connected to the placement blocks 121, and the inner side of the placement slots 112 is provided with threaded grooves that match the screws 122. When the inverter body 1 is in use, heat accumulates inside the inverter body 1 due to prolonged operation. Because of the electrical connection between the fan module 111 and the power supply of the inverter body 1, the fan module 111 rotates. The airflow generated by 111 can cool the inside of the inverter body 1. The filter 12 prevents dust from the outside air from entering the inside of the inverter body 1. When the filter 12 is covered with dust and needs to be cleaned, the screw 122 on the placement block 121 can be turned off. After the screw 122 comes out of the threaded groove inside the placement slot 112, the filter 12 can be removed from the ventilation window 11 for cleaning. After cleaning, the filter 12 can be placed back in its original position and the screw 122 can be turned in the opposite direction to fix the filter 12. This achieves the function of removing heat from the inside of the inverter body 1 during use, thus improving the performance.

[0034] Example 2:

[0035] To address the problem that most existing air conditioner inverters are integrated structures, making maintenance inconvenient and inefficient for staff when internal problems occur, this embodiment discloses the following technical solution, as detailed below. Figure 4 and Figure 5 As shown, a pressing block 131 is slidably connected to the other side of the inverter body 1. A sliding block 132 is fixedly connected to one side of the pressing block 131. A trapezoidal locking block 133 is fixedly connected to the top of the sliding block 132. A reset spring 134 is fixedly connected to one side of the sliding block 132. One end of the reset spring 134 is fixedly connected to the inside of the inverter body 1. Multiple sets of limiting rods 21 and limiting grooves 13 are provided. The limiting rods 21 and limiting grooves 13 slide in cooperation. A locking groove 211 is opened on one side of the limiting rod 21, and the locking groove 211 slides in cooperation with the trapezoidal locking block 133. When the components inside the inverter body 1 are damaged, the pressing block 133 can be pressed. The pressing block 131 located on the other side of the inverter body 1 moves the sliding block 132, causing the trapezoidal locking block 133 to disengage from the slot 211. At this time, the protective cover 2 can be removed from the top of the inverter body 1, and maintenance operations can be performed on the inside of the inverter body 1. When installation is required, the limiting rod 21 at the bottom of the protective cover 2 is aligned with the limiting slot 13 and inserted. At this time, due to the trapezoidal surface of the trapezoidal locking block 133, the limiting rod 21 can be automatically fixed with the trapezoidal locking block 133 during the movement, which realizes the function of making it convenient for staff to open the protective cover 2 and perform maintenance operations, thus improving work efficiency.
