Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to a combined electrical distribution box structure and an air compressor. Background Technology

[0002] Most air compressors are equipped with a distribution box to house the electrical control components. Currently, there are two main types of distribution boxes for air compressor chassis on the market: independent distribution boxes and distribution boxes integrated with the column and door panel. Independent distribution boxes are usually mounted directly on the chassis base, which can easily cause resonance during air compressor operation, increasing overall vibration and affecting the stability of the electrical control components. While distribution boxes with integrated columns and door panels experience less vibration than independent boxes, replacement requires replacing the entire column and door panel, making the installation and removal process more cumbersome and costly.

[0003] The technical problem to be solved by this application is: how to solve the problems of excessive vibration, low stability, cumbersome installation and removal, and high replacement cost of existing air compressor distribution boxes. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a combined power distribution box structure and an air compressor, which has the characteristics of simple and stable structure and can reduce vibration and cost.

[0005] The technical solution adopted by this utility model is as follows: a combined distribution box structure, including a chassis base, a chassis column and a distribution box body. The chassis column is set on one side of the chassis base. The bottom of the distribution box body is detachably connected to the chassis base. The side of the distribution box body is detachably connected to the chassis column. The chassis base, chassis column and distribution box body constitute a space for installing power distribution facilities.

[0006] The combined distribution box structure of this application utilizes the distribution box body, chassis base, and chassis columns to form an independent space for installing electrical control components. This saves the material of a base plate and a side plate, reducing the overall cost of the distribution box. Furthermore, the distribution box body has multiple connection points with the chassis, making the structure more stable and reliable, effectively reducing vibration and protecting the electrical control components. In addition, the distribution box body is detachably connected to the chassis base and chassis columns, making installation and removal more convenient. The cost of replacing the distribution box in the future is also cheaper than that of a separate distribution box or a distribution box that is integrally formed with the door panel and columns.

[0007] In some embodiments, the distribution box body includes a side plate, a back plate, and a top plate. The bottom of the side plate is connected to the chassis base, the top of the side plate is connected to the top plate, one side of the side plate is connected to the back plate, the bottom of the back plate is connected to the chassis base, the top of the back plate is connected to the top plate, and the side of the back plate and the top plate away from the side plate is connected to the chassis column.

[0008] By adopting the above technical solution, the main body of the distribution box and the base of the chassis share a base plate, and the main column of the chassis share a side plate, which can save the parts of the distribution box and thus save the cost of the distribution box.

[0009] In some implementations, the side panels, back panel, and top panel are integrally formed.

[0010] By adopting the above technical solution, the integrated distribution box structure is more stable, which is beneficial to protecting the electrical components inside the distribution box.

[0011] In some implementations, the bottom of the side panel and / or back panel is provided with a first flange, which is detachably connected to the chassis base by fasteners.

[0012] By adopting the above technical solution, the structural strength of the side panel and / or back panel can be improved by setting the first flange, and the side panel and / or back panel can also be easily connected to the chassis base by fasteners.

[0013] In some implementations, a second flange is provided on the side of the back panel and / or top panel near the chassis column, and the second flange is detachably connected to the chassis column by fasteners.

[0014] By adopting the above technical solution and setting a second flange, the structural strength of the back panel and / or top panel can be improved, and the back panel and / or top panel can be easily connected to the chassis column by fasteners.

[0015] In some embodiments, a third flange is provided on the side of the side panel and / or top panel away from the back panel, and a folded edge is provided on the edge of the chassis column, with the end of the third flange near the chassis column abutting against the folded edge.

[0016] By adopting the above technical solution, the third flange can improve the structural strength of the side plate and / or top plate. At the same time, when equipped with a door plate, it can increase the contact area with the door plate, making the overall structure of the distribution box more stable. Furthermore, the third flange abuts against the folded edge of the chassis column, which can increase the contact area between the top plate and the chassis column, making the structure more stable and helping to prevent deformation and reduce vibration.

[0017] In some embodiments, the distribution box body also includes a reinforcing column, which is connected to the side plate, and the bottom of the reinforcing column abuts against the chassis base.

[0018] By adopting the above technical solution, the reinforcing column can improve the structural strength of the distribution box body, and at the same time increase the connection points between the distribution box body and the chassis, making the distribution box structure more stable and reliable.

[0019] In some implementations, the chassis base is provided with an air inlet, which is equipped with a grille, and the air inlet is located wholly or partially at the bottom of the accommodating space.

[0020] By adopting the above technical solution, by opening an air inlet at the bottom of the main body of the distribution box, the original air-cooling heat dissipation system of the chassis can be used to dissipate heat inside the distribution box, which helps to reduce the ambient temperature of electrical components during operation, thereby extending the service life of electrical components and improving their operational stability.

[0021] In some embodiments, a mesh cover is provided at the bottom of the chassis base, the mesh cover covers the air inlet and forms a cavity for accommodating the filter or sound insulation component, and the chassis base is provided with a mounting groove communicating with the cavity, the mounting groove being used for loading and unloading the filter or sound insulation component.

[0022] By adopting the above technical solution, sound insulation or filter components can be placed inside the cavity to prevent dust from entering the distribution box, reduce dust accumulation, improve heat dissipation efficiency, and reduce vibration. The installation slot facilitates the replacement of filter components or sound insulation components and makes daily maintenance easier.

[0023] This application also provides an air compressor, including a casing and an air compression mechanism built into the casing, and also includes the above-mentioned combined electrical distribution box structure. Attached Figure Description

[0033] Please see Figures 1 to 5 The present invention provides a preferred embodiment of a combined distribution box structure 100, comprising a chassis base 10, a chassis column 20, and a distribution box body 30. The chassis column 20 is disposed on one side of the chassis base 10. The bottom of the distribution box body 30 is detachably connected to the chassis base 10, and the side of the distribution box body 30 is detachably connected to the chassis column. The chassis base 10, chassis column 20, and distribution box body 30 constitute an accommodating space for installing power distribution facilities. The combined distribution box structure of this application has the characteristics of simple and stable structure, which can effectively reduce the resonance generated between the distribution box and the air compressor chassis and reduce production and installation costs.

[0034] like Figure 4 and Figure 5As shown, specifically, the distribution box body 30 includes a side plate 31, a back plate 32, and a top plate 33. The bottom of the side plate 31 is connected to the chassis base 10, the top of the side plate 31 is connected to the top plate 33, one side of the side plate 31 is connected to the back plate 32, the bottom of the back plate 32 is connected to the chassis base 10, the top of the back plate 32 is connected to the top plate 33, and the sides of the back plate 32 and the top plate 33 away from the side plate 31 are connected to the chassis column 20. The distribution box body 30 shares a base plate with the chassis base 10 and a side plate 31 with the chassis column 20, which can save on the components of the distribution box, thereby saving the cost of the distribution box. Moreover, the distribution box body 30 is detachable, and the cost of replacement in the future is also lower.

[0035] Preferably, the side panel 31, back panel 32, and top panel 33 are integrally formed. The integrally formed distribution box body 30 has a more stable structure, which is beneficial for protecting the electrical components inside the distribution box.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, the bottom of the side panel 31 and / or the back panel 32 is provided with a first flange 34, which is detachably connected to the chassis base 10 by fasteners. By providing the first flange 34, the structural strength of the side panel 31 and / or the back panel 32 can be improved, and at the same time, it can also facilitate the connection between the side panel 31 and / or the back panel 32 and the chassis base 10 by fasteners.

[0037] Furthermore, the back panel 32 and / or top panel 33 are provided with a second flange 35 on the side near the chassis column 20. The second flange 35 is detachably connected to the chassis column 20 by fasteners. By providing the second flange 35, the structural strength of the back panel 32 and / or top panel 33 can be improved, while also facilitating the connection between the back panel 32 and / or top panel 33 and the chassis column 20 by fasteners.

[0038] Furthermore, a third flange 36 is provided on the side of the side panel 31 and / or top panel 33 away from the back panel 32, and a folded edge 21 is provided on the edge of the chassis column 20. The end of the third flange 36 near the chassis column 20 abuts against the folded edge 21. The third flange 36 can improve the structural strength of the side panel 31 and / or top panel 33. At the same time, when equipped with a door panel, it can increase the contact area with the door panel, making the overall structure of the distribution box more stable. The contact between the third flange 36 and the folded edge 21 of the chassis column 20 can increase the contact area between the top panel 33 and the chassis column 20, making the structure more stable and helping to prevent deformation and reduce vibration.

[0039] Preferably, the first flange 34 is connected to the chassis base 10 and the second flange 35 is connected to the chassis column 20 by bolts. In other embodiments, fasteners may also be rivets, self-tapping screws, etc.

[0040] Furthermore, in order to reduce vibration, shock-absorbing components can be added at the connection between the distribution box body 30 and the chassis base 10 and chassis column 20.

[0041] like Figure 4 As shown, in one embodiment, the distribution box body 30 also includes a reinforcing column 37, which is connected to the side plate 31, and the bottom of the reinforcing column 37 abuts against the chassis base 10. The reinforcing column 37 can improve the structural strength of the distribution box body 30, and also increase the connection points between the distribution box body 30 and the chassis, making the distribution box structure more stable and reliable. To further improve the structural stability, the top of the reinforcing column 37 can also be connected to the top of the chassis or other structural components.

[0042] Preferably, such as Figure 5 As shown, the reinforcing column 37 is a hollow structure, and a wire groove 371 is provided inside the reinforcing column 37 to facilitate the arrangement of wire harnesses.

[0043] Because the electrical components inside the distribution box generate heat during operation, heat dissipation measures are needed to ensure their normal operation and extend their lifespan. Therefore, an air inlet 11 is provided on the chassis base 10, and the air inlet 11 is equipped with a grille. All or part of the air inlet 11 is located at the bottom of the accommodating space. By opening the air inlet 11 at the bottom of the distribution box body, the original air-cooling system of the chassis can be used to dissipate heat inside the distribution box, which helps to reduce the ambient temperature of the electrical components during operation, thereby extending the service life of the electrical components and improving their operational stability.

[0044] like Figure 3 As shown, a mesh cover 12 is provided at the bottom of the chassis base 10. The mesh cover 12 covers the air inlet 11 and forms a cavity for accommodating filter components or sound insulation components. The chassis base 10 is provided with a mounting groove 13 communicating with this cavity. The mounting groove 13 is used for installing and removing filter components or sound insulation components. Since dust is unavoidable in the working environment of the air compressor, during the operation of the heat dissipation system, external dust will inevitably enter the chassis and distribution box with the airflow, causing dust accumulation inside the chassis and distribution box, thus affecting the heat dissipation effect. By setting up the cavity, sound insulation components or filter components can be placed inside the cavity to prevent dust from entering the distribution box, reduce dust accumulation, improve heat dissipation efficiency, and also reduce vibration. The mounting groove 13 facilitates the replacement of filter components or sound insulation components and facilitates daily maintenance.

[0045] The combined distribution box structure 100 of this application, by means of the distribution box body 30, the chassis base 10, and the chassis column 20, forms an independent space for installing electrical control components. This can save the material of a base plate and a side plate 31, reducing the overall cost of the distribution box. Furthermore, the distribution box body 30 has multiple connection points with the chassis, making the structure more stable and reliable, and effectively reducing vibration to protect the electrical control components. In addition, the distribution box body 30 is detachably connected to the chassis base 10 and the chassis column 20, making installation and removal more convenient. The cost of replacing the distribution box in the future is also cheaper than that of an independent distribution box or a distribution box that is integrally formed with the door panel and column.

[0046] This application also provides an air compressor, including a casing and an air compression mechanism built into the casing, and also including the aforementioned combined electrical distribution box structure 100. Since the air compressor having the aforementioned combined electrical distribution box structure 100 also possesses the aforementioned beneficial effects, it will not be described in detail here.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
