Description

Technical Field

[0001] The utility model relates to the field of circuit breakers, in particular to a circuit breaker bracket structure and an air conditioner. Background Art

[0002] In modern air conditioning systems, especially those for residential and commercial use, electric heating coils are commonly used as auxiliary heating in the indoor unit of the heat exchanger to improve heating efficiency and ensure that the indoor temperature reaches the user's set value quickly and stably. This design aims to compensate for the reduced efficiency of heat pump systems alone in low-temperature environments. The additional heat output of the electric heating coils effectively improves the indoor temperature response speed and comfort level.

[0003] To ensure the safe operation of electric heating devices, systems are equipped with circuit breakers as electrical protection devices, depending on their power levels. The primary function of a circuit breaker is to automatically disconnect the circuit in the event of an overload or short circuit, preventing accidents such as electrical fires. For high-power electric heating devices, due to their high current demands and significant thermal effects, dual circuit breakers in parallel are often required to distribute the current load and enhance system reliability and safety.

[0004] However, when installing these electric heating devices and their associated circuit breakers, air conditioning units currently on the market face the problems of a single bracket design and poor compatibility. Specifically, existing bracket designs are often only compatible with a single type of circuit breaker (i.e., only suitable for single circuit breakers or only suitable for dual circuit breakers), and lack the ability to flexibly adjust or convert. As a result, in actual applications, when the power of the electric heating device or the circuit breaker configuration needs to be changed, the entire bracket system often needs to be replaced at the same time, which not only increases installation costs but also reduces the convenience and flexibility of maintenance.

[0005] Furthermore, as users increasingly demand personalized air conditioning systems, bracket designs that can flexibly adjust circuit breaker configurations to meet varying power requirements and achieve universal compatibility for both single and dual circuit breakers have become increasingly important. The limitations of current bracket designs clearly fail to meet this market demand, limiting the adaptability of air conditioning systems and user satisfaction.

[0006] In summary, in order to solve the problem that the circuit breaker bracket of the electric heating device in the existing air-conditioning unit has a single function and cannot be universally adjusted, it is urgent to develop a new bracket design to adapt to electric heating devices of different power, thereby improving the flexibility, safety and user satisfaction of the system. Utility Model Content

[0007] In order to solve the technical problem of single function of circuit breaker bracket in the prior art, the utility model provides a circuit breaker bracket structure and an air conditioner.

[0008] The technical solution adopted in this utility model is:

[0009] The utility model provides a circuit breaker bracket structure, comprising: a mounting plate, wherein the mounting plate is provided with mounting positions for arranging a plurality of circuit breakers side by side; the mounting plate is further provided with a plurality of fixing positions, wherein fixing bars spanning the mounting positions can be installed at the fixing positions; when one or more circuit breakers are arranged in the mounting positions, the fixing bars can be selectively installed at fixing positions corresponding to the number of circuit breakers to limit the positions of the circuit breakers.

[0010] Furthermore, fixing holes for installing the fixing strip are respectively provided at both ends of the fixing position, and both ends of the fixing strip are respectively connected to the two fixing holes at one fixing position by screws.

[0011] Furthermore, the mounting positions are three long strip openings of the same length and arranged parallel to each other on the mounting plate. The back of the circuit breaker is provided with a clamping portion for clamping into the three opening positions, and the same position of the three openings is used to clamp one circuit breaker.

[0012] Furthermore, a buckle is provided on the mounting plate for fixing the wiring harness of the circuit breaker.

[0013] Furthermore, at least one side of the mounting plate is provided with a folded edge bent backwards, and the folded edge is provided with at least one third fixing hole for connecting with a screw of the mounting surface.

[0014] Furthermore, the folded edges are arranged on two adjacent sides of the mounting plate.

[0015] Furthermore, the mounting plate is provided with a regular hexagonal mounting hole for mounting a grounding screw.

[0016] Furthermore, a rivet nut is provided in the regular hexagonal mounting hole, and the grounding screw is threadedly connected to the rivet nut.

[0017] Furthermore, the grounding screw is an M6 grounding screw and / or an M4 grounding screw.

[0018] An air conditioner comprises any one of the circuit breaker bracket structures.

[0019] Compared to the prior art, the present invention proposes a circuit breaker bracket structure comprising a mounting plate with mounting positions for juxtaposing multiple circuit breakers. The mounting plate also features multiple fixing positions, each of which accommodates a fixing bar that spans the mounting position. When one or more circuit breakers are positioned within the mounting position, the fixing bar can be selectively installed in the fixing positions corresponding to the number of circuit breakers, thereby limiting the position of the circuit breakers. This provides the circuit breaker bracket structure with excellent compatibility and scalability, allowing it to accommodate one or more circuit breakers. This addresses the technical issue of prior art circuit breaker brackets, which have a single function and require the addition or removal of bracket structures to accommodate the addition or removal of circuit breakers.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0028] In modern air conditioning systems, especially those for residential and commercial use, electric heating coils are commonly used as auxiliary heating in the indoor unit of the heat exchanger to improve heating efficiency and ensure that the indoor temperature reaches the user's set value quickly and stably. This design aims to compensate for the reduced efficiency of heat pump systems alone in low-temperature environments. The additional heat output of the electric heating coils effectively improves the indoor temperature response speed and comfort level.

[0029] To ensure the safe operation of electric heating devices, systems are equipped with circuit breakers as electrical protection devices, depending on their power levels. The primary function of a circuit breaker is to automatically disconnect the circuit in the event of an overload or short circuit, preventing accidents such as electrical fires. For high-power electric heating devices, due to their high current demands and significant thermal effects, dual circuit breakers in parallel are often required to distribute the current load and enhance system reliability and safety.

[0030] However, when installing these electric heating devices and their associated circuit breakers, air conditioning units currently on the market face the problems of a single bracket design and poor compatibility. Specifically, existing bracket designs are often only compatible with a single type of circuit breaker (i.e., only suitable for single circuit breakers or only suitable for dual circuit breakers), and lack the ability to flexibly adjust or convert. As a result, in actual applications, when the power of the electric heating device or the circuit breaker configuration needs to be changed, the entire bracket system often needs to be replaced at the same time, which not only increases installation costs but also reduces the convenience and flexibility of maintenance.

[0031] Furthermore, as users increasingly demand personalized air conditioning systems, bracket designs that can flexibly adjust circuit breaker configurations to meet varying power requirements and achieve universal compatibility for both single and dual circuit breakers have become increasingly important. The limitations of current bracket designs clearly fail to meet this market demand, limiting the adaptability of air conditioning systems and user satisfaction.

[0032] In summary, in order to solve the problem that the circuit breaker bracket of the electric heating device in the existing air-conditioning unit has a single function and cannot be universally adjusted, it is urgent to develop a new bracket design to adapt to electric heating devices of different power, thereby improving the flexibility, safety and user satisfaction of the system.

[0033] like Figure 1-4As shown, the utility model proposes a circuit breaker 3 bracket structure, including: a mounting plate 1, the mounting plate 1 is provided with a mounting position for mounting multiple circuit breakers 3 side by side, and one or more circuit breakers 3 can be mounted on the mounting position. When there is only one circuit breaker 3, the circuit breaker 3 is set at the head end of the mounting position; when there are multiple circuit breakers 3, multiple circuit breakers 3 are arranged side by side from the head end to the end of the mounting position. The mounting plate is also provided with multiple fixing positions, and a fixing bar 2 that spans the mounting position can be installed at the fixing position. The fixing bar 2 is in the shape of a bar. When one or more circuit breakers are mounted in the mounting position, the fixing bar 2 can be optionally installed at the fixing position corresponding to the number of circuit breakers 3 to limit the circuit breakers 3. After the circuit breaker 3 is stuck in the mounting position, the fixing bar 2 is installed on the mounting plate 1 to prevent the circuit breaker 3 stuck in the mounting position from moving and falling off.

[0034] The circuit breaker 3 bracket structure proposed in the present invention consists of a mounting plate 1 and a fixing bar 2, which is easy to manufacture and install. The mounting plate 1 is provided with a mounting position for clamping the circuit breaker 3, so that one or more circuit breakers 3 can be flexibly installed. This design allows users to freely choose the number of circuit breakers 3 to be installed according to actual needs, thereby meeting different circuit protection requirements. After the circuit breaker 3 is clamped in the mounting position, the circuit breaker 3 can be firmly fixed by installing the fixing bar 2, effectively preventing the circuit breaker 3 from moving and falling off in the mounting position, thereby improving the safety of the circuit. Since the design of the mounting position allows multiple circuit breakers 3 to be arranged in sequence from the head end to the end, the bracket structure has good compatibility and scalability. As the circuit demand increases, users can easily increase the number of circuit breakers 3 without replacing the entire bracket structure.

[0035] In a further embodiment, mounting plate 1 is provided with a mounting position for retaining circuit breakers 3, which can accommodate one or more circuit breakers 3. Fixing holes for mounting fixing bars 2 are provided at each end of the fixing position. When there is only one circuit breaker 3, the circuit breaker 3 is positioned at the head end of the mounting position; when there are multiple circuit breakers 3, the multiple circuit breakers 3 are arranged sequentially from the head end to the tail end of the mounting position. Fixing bar 2 is strip-shaped. After a circuit breaker 3 is secured to the mounting position, the ends of the fixing bar are screwed to the two fixing holes in one mounting position, securing it to mounting plate 1.

[0036] The fixing method using the fixing bar 2 and screws 4 can greatly enhance the stability of the circuit breaker 3 on the mounting plate 1. This design can effectively prevent the circuit breaker 3 from moving or falling off during installation, thereby improving the safety of the circuit. The design using the fixing holes and fixing bar 2 makes the installation process of the circuit breaker 3 simpler and faster. The user only needs to snap the circuit breaker 3 into the installation position and then fix the fixing bar 2 to the fixing position of the mounting plate 1 using the screws 4. This installation method not only saves time but also reduces the difficulty of installation. Because the connection method of the fixing bar 2 and screws 4 is relatively simple, the user can easily remove and reinstall the fixing bar 2 and circuit breaker 3 when maintenance or replacement of the circuit breaker 3 is required. This design reduces maintenance costs and improves maintenance efficiency.

[0037] In a further embodiment, the fixing holes at each set of fixing positions are: a first fixing hole located above the mounting position and a second fixing hole located below the mounting position, and the ends of the fixing bar 2 are respectively connected to the first fixing hole and the second fixing hole by screws 4. The multiple fixing positions are respectively arranged between the first and last ends of the mounting position and are located at positions that are an integer multiple of the width of the circuit breaker 3.

[0038] For example, starting from the head end of the mounting position, a first fixing position is set at the width of one circuit breaker 3, a second fixing position is set at the width of two circuit breakers 3, and a third fixing position is set at the width of three circuit breakers 3. When there is only one circuit breaker 3, the circuit breaker 3 is clamped at the head end of the mounting position, and the fixing bar 2 is fixed to the fixing hole at the first fixing position. When there are two circuit breakers 3, the two circuit breakers 3 are clamped into the mounting position in sequence from the head end, and the fixing bar 2 is fixed to the fixing hole at the second fixing position. When there are three circuit breakers 3, the three circuit breakers 3 are clamped into the mounting position in sequence from the head end, and the fixing bar 2 is fixed to the fixing hole at the third fixing position.

[0039] Each set of fixing positions is equipped with a first fixing hole located above the mounting position and a second fixing hole located below the mounting position. This design ensures that the fixing bar 2 can be securely fixed to the mounting plate 1 from both the top and bottom sides, further enhancing the stability of the circuit breaker 3. Furthermore, each set of fixing positions is located between the beginning and end of the mounting position, at locations that are integer multiples of the width of the circuit breaker 3. For example, starting from the beginning of the mounting position, a fixing position is provided for each additional width of the circuit breaker 3. This layout ensures that no matter how many circuit breakers 3 are installed, a matching fixing position can be found, ensuring that each circuit breaker 3 is effectively secured. The ends of the fixing bar 2 are connected to the first and second fixing holes at a fixing position using screws 4. This connection method is simple and reliable, ensuring the stability of the fixing bar 2 on the mounting plate 1. By simultaneously fixing from both the top and bottom sides and locating each set of fixing holes at locations that are integer multiples of the width of the circuit breakers 3, no matter how many circuit breakers 3 are installed, they can maintain a high degree of stability on the mounting plate 1. This design helps prevent the circuit breakers 3 from moving or falling off during installation, thereby improving circuit safety. Because the fixing points are arranged according to the width of an integer multiple of the number of circuit breakers 3, the bracket structure can flexibly accommodate different numbers of circuit breakers 3. This adaptability makes the bracket structure widely applicable to circuit systems of varying scales and complexities.

[0040] In a further embodiment, the mounting plate 1 is provided with mounting locations for retaining the circuit breaker 3, and one or more circuit breakers 3 can be installed in the mounting locations. The mounting locations are three elongated openings of the same length provided on the mounting plate 1, namely a first opening 31, a second opening 32, and a third opening 33. The back of the circuit breaker 3 is provided with a snap-in portion for snapping into the three openings. The first opening 31, the second opening 32, and the third opening 33 are elongated, horizontally arranged, and parallel to each other. The first opening 31, the second opening 32, and the third opening 33 are located at the same position for retaining a circuit breaker 3. The three snap-in portions on the back of the circuit breaker 3 snap into the same position of the three openings. After the circuit breaker 3 is snapped into the mounting location, the fixing bar is installed at the corresponding mounting location using screws 4 to restrict the position of the circuit breaker.

[0041] Mounting plate 1 is provided with a mounting position for retaining circuit breakers 3. This mounting position can accommodate one or more circuit breakers 3, providing users with considerable flexibility. Users can choose to install an appropriate number of circuit breakers 3 based on their actual needs to meet varying circuit protection requirements. The design of three elongated openings (first opening 31, second opening 32, and third opening 33) facilitates the installation and removal of circuit breakers 3. Users can easily install or remove circuit breakers 3 at any location as needed.

[0042] In a further embodiment, a buckle 8 is provided on the mounting plate 1 for fixing the wiring harness of the circuit breaker 3 .

[0043] Securing the wiring harness of circuit breaker 3 with clips 8 effectively organizes and restrains the cables, preventing them from being scattered disorganized, thereby improving the aesthetics and neatness of the entire electrical system. This secured harness reduces the risk of short circuits or disconnections caused by loose or accidentally touching cables, enhancing the safety of the electrical system. It also avoids safety hazards during operation or maintenance caused by cable disarray.

[0044] In a further embodiment, a regular hexagonal mounting hole is provided on the mounting plate 1 for mounting the grounding screw 4 .

[0045] If the user needs to use the grounding screw 4, multiple rivet nuts 7 of different specifications can be fixed on the bracket body through the regular hexagonal mounting holes with the grounding symbol reserved near the mounting plate 1. Then, multiple grounding screws of different specifications such as M4 grounding screw 6 and M6 grounding screw 5 can be selected, and the rivet nuts 7 of different specifications can be aligned with the corresponding positions and tightened to complete the installation of the grounding screws.

[0046] In a further embodiment, at least one side of the mounting plate 1 is provided with a folded edge bent backwards, and the folded edge is provided with at least one third fixing hole for connecting with the mounting surface screw 4 .

[0047] The hem design increases the contact area between the fixing strip 2 and the mounting surface, thereby improving the stability of the connection. When the mounting plate 1 is connected to the mounting surface via screws 4, the hem provides better support, reducing the risk of loosening or deformation due to uneven force. The third fixing hole on the hem simplifies the installation process. The design of the mounting plate 1 and the third fixing hole ensures a more uniform force distribution on the mounting surface. This helps reduce stress concentration and improves the overall structural strength. Even under heavy loads, the mounting plate 1 maintains stable performance and is less susceptible to damage.

[0048] In a further embodiment, the folded edges are provided on two adjacent sides of the mounting plate 1 .

[0049] The design of the two side hems allows the mounting plate 1 to adapt to mounting surfaces of varying shapes and sizes. Technicians can choose to install screws 4 on different hems as needed to ensure that the mounting plate 1 is securely fixed to different surfaces. Providing hems on adjacent sides further facilitates installation.

[0050] The present invention also provides an air conditioner, comprising the circuit breaker 3 support structure of the present invention.

[0051] Compared to the prior art, the present invention proposes a circuit breaker (3) support structure, comprising a mounting plate 1 with mounting positions for juxtaposing multiple circuit breakers. The mounting plate also features multiple fixing positions, each of which can be fitted with a fixing bar that spans the mounting position. When one or more circuit breakers are positioned within the mounting position, the fixing bar can be selectively installed in the fixing positions corresponding to the number of circuit breakers, limiting the position of the circuit breakers. This provides the circuit breaker (3) support structure with excellent compatibility and scalability, allowing it to accommodate one or more circuit breakers (3). This addresses the technical issue in the prior art where circuit breaker (3) supports have a single function and require the addition or removal of the support structure to accommodate the addition or removal of circuit breakers (3).
