Description

Technical Field

[0001] This utility model relates to the field of frequency converter technology, and in particular to a lightweight frequency converter structure. Background Technology

[0002] A frequency converter is an electronic device used to control the speed and torque of an AC motor, and it is widely used in industrial automation systems. With technological advancements and increasing application demands, lightweight frequency converters are gradually becoming an important market trend. Lightweight frequency converters not only reduce the weight and size of equipment but also improve energy efficiency and reliability, meeting the modern industrial demand for efficient, compact, and flexible equipment.

[0003] Conventional frequency converters are mainly used as electronic devices to control the speed and torque of motors, adjusting the motor speed by changing the power supply frequency. According to the authorized publication number "CN219660268U", a lightweight internal heat sink assembly for a frequency converter is disclosed, relating to the field of frequency converter technology. It includes: a frequency converter body, with circuit components internally arranged; mounting frames fixedly installed on both sides of the internal part of the frequency converter body; mounting plates movably inserted into the inner surface walls of the two mounting frames; multiple heat sink bodies fixedly inserted into the front surface of the mounting plates; and multiple holes A on one side of the outer wall of each of the multiple heat sink bodies, allowing a cooling fan to be activated to blow heat out of the frequency converter body. Compared to existing devices, this device uses mounting slots to install the mounting plates inside the frequency converter body, eliminating the need for screws and improving convenience. Furthermore, the holes A and B increase the contact area with air and improve ventilation, while the cooling fan enhances the overall heat dissipation function of the device.

[0004] Currently, some frequency converters require carrying during use. This carrying process involves not only human carrying but also carrying on mobile robots. If these frequency converters are not designed to be lightweight, their increased size will occupy more space, affecting the layout and ease of use of the equipment, as well as increasing the overall weight, which will reduce the range of the mobile equipment and increase its power consumption. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a lightweight frequency converter structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight frequency converter structure, including a base, a housing covering the top of the base, a touch screen installed on the front of the housing, a back plate fixedly installed on the back of the housing, and a power interface fixedly embedded in the middle of the back plate.

[0007] The base has a heat dissipation vent at its lower end that penetrates through it, and a dustproof mesh is embedded inside the heat dissipation vent. The outer shell has heat dissipation vents on both sides that penetrate through it, and a dustproof mesh is embedded inside the heat dissipation vent.

[0008] A circuit board is fixedly installed at the top of the inner part of the housing, and the touch screen and power interface are respectively connected to the circuit board through data cables.

[0009] Preferably, the dustproof net one and the dustproof net two have the same structure. The dustproof net one is composed of a base layer and a surface layer, and the surface layer is fixed to the surface of the base layer.

[0010] Preferably, the base layer is made of non-woven filter material.

[0011] Preferably, the surface layer is made of aluminum alloy wire mesh material.

[0012] Preferably, the lower end of the base is fixed with feet distributed at the four apex positions, and the feet are made of rubber block material.

[0013] Preferably, the base has alignment grooves on both sides inside, and alignment blocks are fixed at the lower ends of both sides of the outer shell. The alignment blocks slide into and connect with the alignment grooves.

[0014] Preferably, the alignment block has a groove inside, and a locking pin is slidably sleeved inside the groove. The end of the locking pin has a curved structure, and a spring is provided inside the groove. The two ends of the spring are fixedly installed to the inner wall of the groove and the end face of the locking pin, respectively.

[0015] Preferably, the alignment groove has an arc-shaped groove inside, and the inner arc surface of the arc-shaped groove abuts against the end curved surface of the locking pin.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. This solution significantly reduces the weight of the control area by replacing traditional buttons and panel components with a touch screen, while simplifying the operation interface and improving the user experience. The shell and base are made of lightweight aluminum alloy and combined with multiple hollow heat dissipation vents, which further reduces the weight of the overall structure, making it easy to move and install, while ensuring the sturdiness and durability of the equipment.

[0018] 2; As described in 1, the dustproof net combines a non-woven fabric filter and an aluminum alloy wire mesh in a double-layer structure, which effectively filters external dust particles while ensuring air circulation and heat dissipation efficiency.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Reference Figures 1-6 The lightweight inverter structure includes a base 1, a housing 11 covering the top of the base 1, a touch screen 12 installed on the front of the housing 11, a back plate 13 fixedly installed on the back of the housing 1, and a power interface 14 fixedly embedded in the middle of the back plate 13. The touch screen 12 can reduce the need for conventional buttons and corresponding panel components, thereby reducing the weight of the control area.

[0030] The lower end of the base 1 has a heat dissipation vent 15 that penetrates its interior. A dustproof mesh 16 is embedded inside the heat dissipation vent 15. The two sides of the outer shell 11 have heat dissipation vents 17 that penetrate its interior. A dustproof mesh 18 is embedded inside the heat dissipation vent 17. The base 1 and the outer shell 11 both form a hollow structure through the corresponding heat dissipation vents, which can further reduce the weight of the material. The base 1 and the outer shell 11 are both made of lightweight aluminum alloy material.

[0031] A circuit board 19 is fixedly installed at the top of the inner casing 11. The touch screen 12 and the power interface 14 are respectively connected to the circuit board 19 via data cables. The circuit board 19 facilitates the normal connection of the touch screen 12 and the power interface 14 to power.

[0032] Among them, the dustproof net 16 and the dustproof net 2 18 have the same structure. The dustproof net 16 is composed of a base layer 1601 and a surface layer 1602. The surface layer 1602 is fixed on the surface of the base layer 1601. Through the composite filter structure, not only can the overall strength of the structure be guaranteed, but also fine dust can be isolated.

[0033] The base layer 1601 is made of non-woven filter material, which can filter external particulate dust, while ensuring normal air passage and heat dissipation within the space of the outer shell 11 and the base 1.

[0034] The surface layer 1602 is made of aluminum alloy wire mesh, which can clamp and position the base layer 1601, while ensuring the supporting strength of the overall dustproof structure.

[0035] The base 1 has four feet 2 fixed at its lower end along the four corners. The feet 2 are made of rubber block material and can support the base 1 and suspend it in the air, so that the heat dissipation vent 15 can dissipate heat normally.

[0036] The base 1 has alignment grooves 3 on both sides inside, and alignment blocks 31 are fixed at the lower ends of both sides of the outer shell 11. The alignment blocks 31 slide into the alignment grooves 3 for docking. Through the cooperation of the alignment blocks 31 and the alignment grooves 3, the base 1 and the outer shell 11 can be quickly positioned and docked.

[0037] The positioning block 31 has a groove 32 inside, and a locking pin 33 is slidably sleeved inside the groove 32. The end of the locking pin 33 has a curved surface structure. A spring 34 is installed inside the groove 32. The two ends of the spring 34 are fixedly installed to the inner wall of the groove 32 and the end face of the locking pin 33, respectively. The spring 34 can ensure the stable extension and repositioning of the locking pin 33.

[0038] The alignment groove 3 has an arc-shaped groove 35 inside. The inner arc surface of the arc-shaped groove 35 abuts against the end curved surface of the locking pin 33. When the outer shell 11 and the base 1 need to be assembled, the alignment block 31 cooperates with the alignment groove 3, so that the end curved surface of the locking pin 33 is squeezed by the groove opening of the alignment groove 3. The compressible spring 34 enters the interior of the groove 32, so that the alignment block 31 can be fully inserted into the alignment groove 3, allowing the base 1 and the outer shell 11 to be fully assembled. When the locking pin 33 When the position corresponds to the position of the arc groove 35, the spring 34 resets the locking pin 33 so that it can spring into the interior of the arc groove 35, thus securing the outer shell 11 and the base 1. Conversely, during disassembly, by pulling the base 1 and the outer shell 11, the end curved surface of the locking pin 33 is pressed against the inner curved surface of the arc groove 35, and the locking pin 33 compresses the spring 34 again and enters the interior of the groove 32, thereby allowing the alignment block 31 and the alignment groove 3 to separate, thus completing the disassembly.

[0039] In practice

[0040] The base 1 and outer shell 11 of this design are made of lightweight aluminum alloy. By creating a hollow design with heat dissipation vents 15 and 17 on their structure, the overall weight is reduced and the heat dissipation efficiency is enhanced. Heat dissipation vent 15 is located at the lower end of the base 1, with dustproof mesh 16 embedded inside. Heat dissipation vent 17 is located on both sides of the outer shell 11, with dustproof mesh 18 embedded inside. Dustproof mesh 16 and dustproof mesh 18 adopt a composite structure, consisting of a base layer 1601 and a surface layer 1602. The base layer 1601 is a non-woven fabric filter, which can filter particulate dust without affecting air circulation. The surface layer 1602 is an aluminum alloy wire mesh, which provides support strength and fixes the base layer 1601. The base 1 is suspended by the feet 2, so that heat dissipation vent 15 can fully contact the outside air. Together with the heat dissipation vent 17 on the side of the outer shell 11, it forms convection heat dissipation, ensuring the stable operation of internal components such as the circuit board 19.

[0041] The base 1 and the outer shell 11 are quickly positioned and connected through the alignment block 31 and the alignment groove 3. The alignment block 31 is fixed to the lower ends of both sides of the outer shell 11 and has a groove 32 inside. The locking pin 33 is slidably sleeved in the groove 32. The end of the locking pin 33 has a curved surface structure and is connected to the inner wall of the groove 32 through the spring 34. The alignment groove 3 is opened on both sides inside the base 1 and has an arc groove 35 on its inner wall. During assembly, the alignment block 31 is inserted into the alignment groove 3, and the curved end of the locking pin 33 is squeezed and compressed by the spring 34 until the locking pin 33 is aligned with the arc groove 35. Then the spring 34 pushes the locking pin 33 into the arc groove 35 to complete the locking. During disassembly, the external force pulls and causes the curved surface of the locking pin 33 to slide and squeeze against the inner wall of the arc groove 35. The spring 34 is compressed again, and the locking pin 33 is disengaged from the arc groove 35, thus separating the base 1 from the outer shell 11.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
