Description

Technical Field

[0001] The utility model relates to the technical field of electric control boxes, in particular to an electric control box and a motor controller. Background Art

[0002] In the prior art, when a connector is at the board end and needs to be sealed with the housing using FIPG (Formed in Place Gasket) glue, the usual design is to apply FIPG glue to the entire sealing surface of the two sealing components. The characteristic of FIPG glue is that it can adapt to different structural shapes for sealing, but there is a problem of difficulty in disassembly, resulting in extremely low maintainability of the components. For example, when sealing two housings together, if FIPG glue is used for sealing, FIPG glue needs to be applied to the circumference of the two housings so that the two housings can be tightly fitted and sealed. However, if disassembly is required, since the two housings are fixed with the same tightness around the entire circumference, there is no entry point. Auxiliary structures or tools are usually required for disassembly, and the integrity of the two housing structures cannot be guaranteed, thereby reducing the maintainability of the housing structure. Utility Model Content

[0003] Based on this, an electric control box and a motor controller are provided to improve the problem in the prior art that when two components are connected circumferentially by FIPG glue, the two components are difficult to disassemble and have poor maintainability due to the difficult-to-disassemble property of FIPG glue.

[0006] The external interface is provided at the abutting position of the upper shell and the lower shell, and an opening structure communicating with the interior of the box body is formed at the abutting position.

[0007] The CIPG glue is applied in a circular shape on the upper or lower shell. The CIPG glue is applied at the junction of the upper and lower shell circumferences. The CIPG glue is cured at high temperature to form a compressible sealing structure on the upper or lower shell.

[0008] FIPG glue is applied to the circumference of the external interface.

[0015] In one implementation, the lower housing includes:

[0027] There is a one-to-one correspondence between the first connection portion and the second connection portion and they are connected by bolts.

[0028] On the other hand, the present invention also provides a motor controller, including an electric control box.

[0029] The beneficial effects of the present invention are as follows: by applying CIPG glue on the upper shell or the lower shell and fixing it at high temperature, the CIPG glue forms a compressible sealing structure on the upper shell or the lower shell, so that when it is fixed to the upper shell and the lower shell, the sealing structure formed by the CIPG glue can be compressed to perform sealing and ensure the sealing effect.

[0039] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0040] Specifically, the full name of FIPG glue 40 is Formed in Place Gasket. FIPG glue 40 includes dispensing and curing when used. FIPG glue 40 can be cured at room temperature. FIPG glue 40 is assembled before curing. After curing, FIPG glue 40 will bond the substrates on both sides to achieve a reliable sealing effect. However, if FIPG glue 40 is used for the entire circumference, there is a problem of difficulty in disassembly. CIPG glue 50 includes dispensing and curing when used. As in the present application, high-temperature curing can be used after dispensing to form a compressible sealing structure. Therefore, when used, CIPG glue can be first applied to the upper shell 10 or the lower shell 20. Through high-temperature curing, a compressible sealing structure is formed on the upper shell 10 or the lower shell 20, so as to facilitate compression sealing when the upper shell 10 and the lower shell 20 are subsequently connected. CIPG glue 50 is often used for planar structure sealing, has strong detachability, and is often used for sealing on a single plane.

[0041] Example 1

[0042] An electric control box, see Figure 1 and Figure 2 The box body includes an upper shell 10, a lower shell 20, an external interface 30, FIPG glue 40 and CIPG glue 50. The upper shell 10 and the lower shell 20 are abutted around and form the main structure of the box body; the external interface 30 is opened at the abutting position of the upper shell 10 and the lower shell 20, and forms an opening structure connected to the inside of the box body at the abutting position. The upper shell 10 and the lower shell 20 together form the circumference of the external interface 30; the CIPG glue 50 is applied in a ring shape on the upper shell 10 or the lower shell 20, and the application position of the CIPG glue 50 is the abutting position of the upper shell 10 and the lower shell 20. The CIPG glue 50 is cured at high temperature to form a compressible sealing structure on the upper shell 10 or the lower shell 20; the FIPG glue 40 is applied on the circumference of the external interface 30.

[0043] According to the present invention, by applying CIPG glue 50 on the upper shell 10 or the lower shell 20 and fixing it at high temperature, the CIPG glue 50 forms a compressible sealing structure on the upper shell 10 or the lower shell 20, so that when it is fixed to the upper shell 10 and the lower shell 20, the sealing structure formed by the CIPG glue 50 can be compressed to perform sealing and ensure the sealing effect. Since the compressible sealing structure of the CIPG glue 50 does not adhere the upper shell 10 and the lower shell 20, it is convenient to disassemble and separate the upper shell 10 and the lower shell 20; in addition, an external interface 30 is provided to facilitate the connection of corresponding parts through the external interface 30 and to connect the inside and outside of the box, and the CIPG glue 40 is applied circumferentially at the external interface 30 and fixed to the The corresponding parts, due to the strong viscosity of the FIPG glue 40, are improved in the stability of the fixation between the parts at the external interface 30 and the box body; the upper shell 10 and the lower shell 20 together surround the peripheral side of the external interface 30, which facilitates the installation, maintenance and disassembly of the parts at the external interface 30; in summary, by adopting the CIPG glue 50 to seal the upper shell 10 and the lower shell 20 over a large area, the sealing between the upper shell 10 and the lower shell 20 is ensured, while the disassembly of the upper shell 10 and the lower shell 20 is facilitated, the maintenance of the box body is facilitated and the maintainability of the box body is improved, and the parts at the external interface 30 are fixed at the same time by the FIPG glue 40, which ensures the stability of the parts at the external interface 30 while minimizing the impact on the disassembly of the upper shell 10 and the lower shell 20.

[0044] Specifically, the CIPG glue 50 can be applied with the aid of a glue gun, so that the CIPG glue 50 is evenly spread on the contact surface between the upper shell 10 and the lower shell 20. The FIPG glue 40 can also be applied with the aid of a glue gun.

[0045] In some embodiments, see Figure 1 and Figure 2 The case also includes an insert 60, which is secured to the external interface 30 around its perimeter with FIPG adhesive 40. The outer wall of the insert 60 forms a corresponding contoured structure with the inner wall of the external interface 30. Thus, the insert 60 is secured to the external interface 30 to connect the interior and exterior of the case. The circumference of the insert 60 is secured to the case with FIPG adhesive 40. Specifically, the circumference of the insert 60 is bonded to both the upper shell 10 and the lower shell 20, ensuring the stability of the insert 60 after connection.

[0046] In some embodiments, see Figure 1 and Figure 4The external interface 30 is provided on the upper end surface of the lower housing 20. The upper housing 10 surrounds one side of the top of the external interface 30 and abuts the top of the plug-in 60. CIPG glue 50 is applied to the upper housing 10. Thus, the upper housing 10 surrounds one side of the top of the external interface 30 and abuts the top of the plug-in 60. In this embodiment, by optimizing the position of the plug-in 60, only the top of the plug-in 60 is connected to the upper housing 10 via the FIPG glue 40. When the upper housing 10 and the lower housing 20 are separated and the upper housing 10 is removed, the only part of the upper housing 10 connected to the rest of the housing via the FIPG glue 40 is the top of the plug-in 60. This reduces the disassembly range of the FIPG glue 40, facilitates removal of the upper housing 10, and improves the maintainability of the housing. In addition, applying the CIPG glue 50 to the relatively flat upper housing 10 facilitates the curing of the CIPG glue 50 into a closed, annular, compressible sealing structure.

[0047] In some embodiments, see Figure 1 and Figure 4 , the external interface 30 forms a U-shaped groove structure on the lower shell 20. In this way, the external interface 30 with a U-shaped groove structure is provided on the lower shell 20, so that the external interface 30 can be placed in the lower shell 20 and the position of the external interface 30 can be adjusted conveniently.

[0048] In the embodiment, the external interface 30 is a parallelogram structure that is smaller at the bottom and larger at the top, wherein the two parallel sides of the quadrilateral are arranged in the horizontal direction, with the smaller side at the bottom and the larger side at the top, thereby making it easier to insert the plug-in 60.

[0049] In some embodiments, see Figure 4 and Figure 5 The lower housing 20 includes a step 21, which is located on its upper end surface and protrudes toward the upper housing 10. The step 21 serves as a guide for the height of the FIPG adhesive 40. When the CIPG adhesive 50 is applied to the upper housing, the height of the cured CIPG adhesive 50 is controlled to be no less than the height of the step 21, thereby ensuring that the CIPG adhesive 50 deforms to seal the upper and lower housings 10 and 20.

[0050] For details, see Figure 4 and Figure 5 A raised portion 24 is provided on the circumference of the lower shell 20. The raised portion 24 is located on the outside of the CIPG glue 50 and the height of the raised portion 24 is lower than the height of the water in the CIPG glue 50 after curing. The raised portion 24 is used to abut against the upper shell 10 and limit the compression degree of the CIPG glue 50 after curing.

[0051] In some embodiments, see Figure 4 and Figure 5The step 21 is located on the contact surface between the upper shell 10 and the lower shell 20. The step 21 extends to connect with the external interface 30. FIPG glue 40 is applied to the upper shell 10 or the lower shell 20, and the FIPG glue 40 covers the contact area between the upper shell 10 and the step 21. Placing the step 21 on the contact surface between the upper shell 10 and the lower shell 20 facilitates the application of the FIPG glue 40 to the step 21, thereby improving the stability of the connection near the external interface 30.

[0052] Specifically, CIPG glue 50 is best applied on a flat surface with good flatness, so CIPG glue 50 is best applied on the upper shell 10, but CIPG glue 50 can also be applied on the lower shell 20; FIPG glue 40 can be applied on the upper shell 10 or the lower shell 20; when applying the two glues, CIPG glue 50 must be applied first, and after the CIPG glue 50 is cured at high temperature to form a compressible sealing structure, FIPG glue 40 is applied, and then the upper shell 10 or the lower shell 20 is pressed and sealed, and the FIPG glue 40 can be cured at room temperature.

[0053] In the embodiment, see Figure 3 and Figure 5 The FIPG glue 40 is applied to the upper shell 10 not only at the position corresponding to the step 21 of the upper shell 10, but also at a position longer than the step 21. That is, after the upper shell 10 and the lower shell 20 are attached, the FIPG glue 40 and the CIPG glue 50 have a local overlapping area, thereby ensuring that the FIPG glue 40 and the CIPG glue 50 evenly cover the connecting surface of the upper shell 10 and the lower shell 20 as a whole, ensuring the connection strength and sealing of the box, and also ensuring the stability of the upper shell 10 and the lower shell 20 after connection.

[0054] In the specific embodiment, see Figure 3 , the shaded area is a schematic diagram of the local position covered by the FIPG glue 40 on the lower shell 20 when the FIPG glue 40 is bonded to the lower shell 20; here, the FIPG glue 40 is not directly applied to the lower shell 20, but is applied to the upper shell 10, and then the upper shell 10 and the lower shell 20 are bonded.

[0055] In the embodiment, since the FIPG glue 40 is applied to the circumference of the external interface 30, since the upper side of the external interface 30 is located on the upper shell 10, and the FIPG glue 40 is applied to the position of the upper shell 10 corresponding to the external interface 30, in addition, the FIPG glue 40 is applied to the position where the upper shell 10 abuts the step portion 21, so that the position where the FIPG glue 40 is applied on the upper shell 10 is a continuous plane; see Figure 3In order to ensure the sealing after the box is connected, the FIPG glue 40 and the CIPG glue 50 have a local overlapping area, that is, the FIPG glue 40 will be applied to the area corresponding to the step portion 21 and extend to the area of the CIPG glue 50.

[0056] In some embodiments, see Figure 4 and Figure 5 Two steps 21 are provided, and the two steps 21 are connected to the two ends of the external interface 30. Thus, the two steps 21 are provided at both ends of the external interface 30, which better indicates the height of the CIPG glue 50. In addition, the FIPG glue 40 is applied to the steps 21, and the two steps 21 improve the stability of the connection between the upper shell 10 and the lower shell 20 at both ends of the external interface 30.

[0057] In the embodiment, the two step portions 21 are symmetrically arranged along the position of the external interface 30 , respectively arranged at the two ends of the external interface 30 , thereby having an indication effect on the height of the glue laying at the two ends of the CIPG glue 50 .

[0058] In some embodiments, see Figure 2 The housing also includes a PCB board 70, which is located within the housing's inner cavity. The lower housing 20 also includes multiple support columns 22, which extend toward the upper housing 10. The support columns 22 are hollow and are connected to the PCB board 70 via bolts. Thus, by providing the support columns 22 within the lower housing 20, the support columns 22 provide support below the PCB board 70. The support columns 22 are then connected to the PCB board 70 via bolts, thereby securing the PCB board 70.

[0059] Based on the above embodiments, see Figure 2 The plug-in 60 is provided with at least two positioning posts and forms a snap-fit structure with the PCB board 70 through the positioning posts. A plurality of pins are also provided between the two positioning posts, and the pins are fixed to the PCB board 70 by welding.

[0060] In some embodiments, see Figure 1 and Figure 2The upper shell 10 includes a plurality of first connecting portions 11 disposed on the outer periphery of the upper shell 10; the lower shell 20 includes a plurality of second connecting portions 23 disposed on the outer periphery of the lower shell 20; the first connecting portions 11 and the second connecting portions 23 are connected in a one-to-one relationship via bolts. Thus, by disposing a plurality of first connecting portions 11 on the outer periphery of the upper shell 10 and a plurality of second connecting portions 23 on the outer periphery of the lower shell 20, and by disposing the first connecting portions 11 and the second connecting portions 23 in a one-to-one relationship, the corresponding first connecting portions 11 and the second connecting portions 23 are connected via bolts or other tools. When the upper shell 10 and the lower shell 20 are connected, the bolts are used to seal and squeeze the cured CIPG adhesive 50, thereby improving the stability of the connection between the upper shell 10 and the lower shell 20. The squeezing of the CIPG adhesive 50 also improves the sealing performance of the upper shell 10 and the lower shell 20.

[0061] In the embodiment, see Figure 4 and Figure 5 The height of the CIPG glue 50 squeezed by the protrusion 24 can be limited, thereby avoiding the problem of excessive squeezing of the CIPG glue 50 by the upper shell 10 and the lower shell 20.

[0062] In the embodiment, see Figure 1 and Figure 2 The box body is rectangular, and the upper shell 10 and the lower shell 20 both have a rectangular cavity structure. The first connection parts 11 have four and are respectively arranged at the four corners near the upper shell 10, and the second connection parts 23 have four and are respectively arranged at the four corners near the lower shell 20.

[0063] According to the solution of the present application, the box includes an upper shell 10, a lower shell 20, an external interface 30, FIPG glue 40, CIPG glue 50, a plug-in 60 and a PCB board 70. During installation, FIPG glue 40 is applied to the outer periphery of the plug-in 60, or FIPG glue 40 is applied to the contact position between the upper shell 10, the lower shell 20 and the plug-in 60, so as to fix the position of the plug-in 60 with the upper shell 10 and the lower shell 20; CIPG glue 50 is applied to the abutting surface of the upper shell 10 or the lower shell 20, and the CIPG glue 50 is cured by high-temperature curing, so that the CIPG glue 50 forms a compressible sealing structure, similar to a sealing ring; specifically, the application area of FIPG glue 40 on the upper shell 10 is not only applied to the contact area between the upper shell 10 and the lower shell 20, but also to the contact area between the upper shell 10 and the lower shell 20. At the position corresponding to the step 21, the length of the FIPG glue 40 applied on the upper shell 10 is longer than the step 21, that is, after the upper shell 10 and the lower shell 20 are attached, the FIPG glue 40 and the CIPG glue 50 have a certain overlapping area, thereby improving the stability and sealing of the connection between the upper shell 10 and the lower shell 20; the PCB board 70 is connected to the lower shell 20 through the support column 22, and the PCB board 70 is connected to the plug-in 60 through the positioning column and welding, and the first connecting part 11 and the second connecting part 23 are fixed together by bolts to fix the upper shell 10 and the lower shell 20 while exerting a certain extrusion sealing effect on the cured CIPG glue 50, thereby ensuring the stability and sealing after the upper shell 10 and the lower shell 20 are connected.

[0064] When disassembling the upper shell 10 and the lower shell 20 of the present application, first remove the bolts connecting the first connecting part 11 and the second connecting part 23. Since CIPG glue 50 is used at the large-area abutment positions of the upper shell 10 and the lower shell 20, the upper shell 10 and the lower shell 20 are not directly adhered except for the parts of FIPG glue 40. The upper shell 10 and the lower shell 20 except for the parts of FIPG glue 40 can be directly separated, which simplifies the separation and disassembly of the upper shell 10 and the lower shell 20. Compared with the structure that is entirely fixed with FIPG glue 40, the difficulty of disassembly is greatly reduced, and the risk of damage to the upper shell 10, the lower shell 20 and the plug-in 60 is also reduced.

[0065] In the embodiment, the thickness of the CIPG glue 50 is controlled at about 2 mm, and the gap between the lower shell 20 and the upper shell 10 is controlled at about 1.2 mm. The gap is controlled by fixing the first connecting part 11 and the second connecting part 23 with bolts. For the FIPG glue 40, since the setting gap of the FIPG glue 40 is usually less than 0.4 mm, the gap of the FIPG glue 40 is smaller than the gap requirement of the CIPG glue 50. Therefore, the provision of the step portion 21 can also assist in controlling the dispensing thickness of the FIPG glue 40.
