[0076] This application provides a chassis and power equipment to improve the reliability of power equipment.

[0077] The chassis 100 will be described in detail below with reference to the accompanying drawings and two embodiments.

[0078] Example 1 of this application

[0079] like Figure 1 As shown, the chassis 100 provided in Embodiment 1 of this application includes: chassis 101 and chassis cover 102.

[0080] The enclosure 101 and the cover 102 are distributed along the first direction. The chassis 100 has a first side 01 and a second side 02 in the second direction. The chassis 100 has a third side 03 and a fourth side 04 in the third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0081] Since the chassis 100 includes a cover 102 and a body 101, and the body 101 and the cover 102 are distributed along a first direction, the cover 102 also has a first side 01 and a second side 02 in the second direction, and a third side 03 and a fourth side 04 in the third direction; correspondingly, the body 101 also has a first side 01 and a second side 02 in the second direction, and a third side 03 and a fourth side 04 in the third direction. Specifically, the first side 01 of the enclosure 101 corresponds to the first side 01 of the cover 102, the second side 02 of the enclosure 101 corresponds to the second side 02 of the cover 102, the third side 03 of the enclosure 101 corresponds to the third side 03 of the cover 102, and the fourth side 04 of the enclosure 101 corresponds to the fourth side 04 of the cover 102. Both the first side 01 of the enclosure 101 and the first side 01 of the cover 102 can be referred to as the first side 01 of the chassis 100, both the second side 02 of the enclosure 101 and the second side 02 of the cover 102 can be referred to as the second side 02 of the chassis 100, both the third side 03 of the enclosure 101 and the third side 03 of the cover 102 can be referred to as the third side 03 of the chassis 100, and both the fourth side 04 of the enclosure 101 and the fourth side 04 of the cover 102 can be referred to as the fourth side 04 of the chassis 100.

[0082] For example, the chassis 100 may be in the form of a cuboid, cube, cylinder or other shapes, and the embodiments of this application do not limit this.

[0083] like Figure 2 and Figure 3 As shown, the housing 101 has an opening (not shown in the figure). A cover 102 is connected to the housing 101. The cover 102 closes the opening of the housing 101, thus restricting the enclosure 1010 between the cover 102 and the housing 101. The electronic components of the electrical equipment are located within the enclosure 1010, thereby reducing the entry of water stains, dust, and other impurities into the enclosure 1010, decreasing the likelihood of damage to the electronic components, and minimizing the impact on the service life of the electrical equipment.

[0084] As mentioned above, the chassis 100 has a first side 01, a second side 02, a third side 03 and a fourth side 04. The cover 102 is connected to the body 101 so that the cover 102 and the body 101 can fit together on the first side 01, the second side 02, the third side 03 and the fourth side 04 of the chassis 100 to ensure a seal.

[0085] The lid 102 and the body 101 are attached together, which can be understood as the lid 102 and the body 101 being directly or indirectly attached together.

[0086] In some embodiments, the cover 102 and the body 101 can be connected by a connecting member 105 to ensure the reliability of the connection between the cover 102 and the body 101, thereby ensuring the sealing of the receiving cavity 1010. The connecting member 105 can be a threaded fastener or a connecting pin, etc. The threaded fastener can include screws, press-fit nuts or pull-fit nuts.

[0087] The lid 102 and the body 101 can be connected by connecting members 105 on at least two of the first side 01, the second side 02, the third side 03, and the fourth side 04. In the locations where there are no connecting members 105, the lid 102 and the body 101 are pressed together by the action of the connecting members 105 to ensure a close fit and seal.

[0088] In order to improve the uniformity of force distribution between the lid 102 and the body 101, the lid 102 and the body 101 are connected by the connecting member 105, which includes a first side 01 and a second side 02, or the lid 102 and the body 101 are connected by the connecting member 105, which includes a third side 03 and a fourth side 04.

[0089] For example, such as Figure 1 and Figure 4 As shown, the lid 102 and the body 101 can be connected by a connecting member 105 on the third side 03 and the fourth side 04. Of course, the lid 102 and the body 101 can also be connected by a connecting member 105 on the first side 01 and the second side 02.

[0090] like Figure 7 and Figure 8 As shown, the lid 102 and the body 101 can be connected via connecting members 105 on the first side 01, the second side 02, the third side 03, and the fourth side 04. Of course, the lid 102 and the body 101 can be connected via connecting members 105 on three of the first side 01, the second side 02, the third side 03, and the fourth side 04.

[0091] In the first embodiment of this application, the box cover 102 has a recessed portion 103, which is recessed from the outside of the receiving cavity 1010 to the inside of the receiving cavity 1010.

[0092] likeFigure 1 , Figure 5 and Figure 6 As shown, part of the recess 103 is located at the connection between the box body 101 and the box cover 102. The recess 103 can deform to the side away from the receiving cavity 1010 under the pressure inside the receiving cavity 1010 and form a pressure relief port 104.

[0093] It should be noted that, Figure 5 and Figure 6 In order to show the receiving cavity 1010, part of the box 101 is hidden, and the area enclosed by the dotted line represents the hidden part.

[0094] In the chassis 100, when the pressure inside the receiving cavity 1010 reaches a pressure value that causes the recess 103 to deform, for example, when the pressure inside the receiving cavity 1010 reaches a set threshold, the recess 103 deforms towards the side away from the receiving cavity 1010 under the action of the pressure inside the receiving cavity 1010. During the deformation of the recess 103, the external force generated by the pressure inside the receiving cavity, such as the external force generated by an explosion inside the receiving cavity 1010, is effectively attenuated, thereby reducing the pressure exerted by the cover 102 inside the receiving cavity 1010. The probability of the cover 102 flying off the housing 101 is reduced, thus improving the reliability of the power equipment. At the same time, part of the recess 103 is located at the connection between the housing 101 and the cover 102. As the recess 103 deforms, it forms a pressure relief port 104, which achieves the function of pressure relief, such as relieving the impact force of an explosion. This reduces the probability of the cover 102 flying off the housing 101 under the pressure in the receiving cavity 1010, and can even prevent the cover 102 from flying off the housing 101 under the pressure in the receiving cavity 1010, thereby improving the reliability of the power equipment.

[0095] It should be noted that the recessed portion 103 deforms towards the side away from the receiving cavity 1010 under the pressure within the receiving cavity 1010. This can be understood as the recessed depth of the deformed recessed portion 103 decreasing, and the deformed recessed portion 103 can be a plane, or, as... Figure 6 As shown, the deformed recess 103 can protrude to the side away from the receiving cavity 1010.

[0096] The recess 103 has a curved structure, which can be a curved structure or a broken line structure. The specific shape of the recess 103 is designed according to the actual situation. Figure 5 and Figure 19 As shown, the recess 103 has a curved structure, and the cross-sectional shape of the recess 103 can be an arc-shaped cross-section. The cross-section of the recess 103 is parallel to the recess direction of the recess 103. For example, the recess direction of the recess 103 is a first direction, and the cross-section of the recess 103 is parallel to the first direction.

[0097] likeFigure 20 and Figure 21 As shown, the recessed portion 103 can have a broken line structure, and the cross-sectional shape of the recessed portion 103 can be trapezoidal. Of course, the cross-section of the recessed portion 103 can also be other shapes.

[0098] like Figure 5 As shown, the recess 103 can be a single portion; as Figure 19 As shown, there can be two recesses 103. Of course, there can also be three or more recesses 103.

[0099] When there are two or more recesses 103, such as Figure 19 As shown, at least two recesses 103 are distributed along a third direction. The third direction is perpendicular to the first direction. Of course, at least two recesses 103 can also be distributed along a second direction, which is perpendicular to the first direction and also perpendicular to the third direction.

[0100] When there are two or more recesses 103, at least two recesses 103 may be located on the same side of the lid 102. For example, at least two recesses 103 may be located on the first side 01, the second side 02, the third side 03 or the fourth side 04 of the lid 102.

[0101] In practice, at least two recesses 103 may be located on different sides of the lid 102. For example, at least one recess 103 may be located on the first side 01 of the lid 102 and at least one recess 103 may be located on the second side 02 of the lid 102; or at least one recess 103 may be located on the first side 01 of the lid 102 and at least one recess 103 may be located on the third side 03 of the lid 102; or at least one recess 103 may be located on the third side 03 of the lid 102 and at least one recess 103 may be located on the fourth side 04 of the lid 102.

[0102] To facilitate the deformation of the lid 102, at least two recesses 103 are located on opposite sides of the lid 102. These opposite sides of the lid 102 may include a first side 01 and a second side 02, or a third side 03 and a fourth side 04. Figure 1 As shown, in order to increase the size of the recessed portion 103 and facilitate its deformation, the recessed portions 103 located on opposite sides of the lid 102 form an integral structure. This can be understood as follows: the recessed portion 103 can extend from the first side 01 of the lid 102 to the second side 02 of the lid 102, or the recessed portion 103 can extend from the third side 03 of the lid 102 to the fourth side 04 of the lid 102.

[0103] In practice, at least two recesses 103 may be located on the same side of the lid 102, and at least two recesses 103 may be located on different sides of the lid 102. For example, at least one recess 103 may be located on the first side 01 of the lid 102, at least one recess 103 may be located on the second side 02 of the lid 102, and at least one recess 103 may be located on the third side 03 of the lid 102.

[0104] like Figure 1 As shown, the recessed portion 103 of the box cover 102 can be recessed along a first direction, the recessed depth of the recessed portion 103 is different in a third direction, and the recessed portion 103 extends along a second direction.

[0105] In practice, the depth of the recess 103 can vary in the second direction, and the recess 103 extends along the third direction. For example, the recess 103 can extend from the third side 03 of the lid 102 to the fourth side 04 of the lid 102.

[0106] like Figure 3 As shown, the lid 102 has a recess 103, and the body 101 has a notch 1011. The notch 1011 accommodates the recess 103 on the lid 102. It can be understood that the notch 1011 and the recess 103 are adapted to each other. In this way, the body 101 and the lid 102 can fit together at the recess 103, thereby facilitating the sealing of the receiving cavity 1010. The recess 103 can also quickly form a pressure relief port 104 through deformation.

[0107] In practice, the housing 101 may not have a notch 1011 that matches the recess 103, and the housing 101 and the cover 102 may be connected by other components.

[0108] As mentioned above, the recess 103 is located at the connection between the housing 101 and the cover 102. The housing 101 and the cover 102 are connected by connecting members 105 on at least two sides of the first side 01, the second side 02, the third side 03 and the fourth side 04. Thus, the housing 100 has a recess 103 on at least one side of the first side 01, the second side 02, the third side 03 and the fourth side 04. It can also be understood that the cover 102 has a recess 103 on at least one side of the first side 01, the second side 02, the third side 03 and the fourth side 04.

[0109] For example, such as Figure 1 As shown, the lid 102 has a recess 103 on the first side 01 and the second side 02. In this case, the portion of the lid 102 between the first side 01 and the second side 02 may also have a recess 103, or may not have a recess 103. Of course, the lid 102 may also have a recess 103 on either the first side 01 or the second side 02.

[0110] For example, the lid 102 has recesses 103 on the third side 03 and the fourth side 04. In this case, the portion of the lid 102 between the third side 03 and the fourth side 04 may also have recesses 103, or may not have recesses 103. Of course, the lid 102 may also have recesses 103 on either the third side 03 or the fourth side 04.

[0111] For example, the lid 102 has recesses 103 on the first side 01, the second side 02, and the third side 03. In this case, the portion of the lid 102 between the first side 01 and the second side 02 may also have a recess 103.

[0112] For example, the lid 102 has recesses 103 on the first side 01, the second side 02, and the fourth side 04. In this case, the portion of the lid 102 between the first side 01 and the second side 02 may also have a recess 103.

[0113] For example, the lid 102 has recesses 103 on the first side 01, the third side 03, and the fourth side 04. In this case, the portion of the lid 102 between the third side 03 and the fourth side 04 may also have a recess 103.

[0114] For example, the lid 102 has recesses 103 on the second side 02, the third side 03, and the fourth side 04. In this case, the portion of the lid 102 between the third side 03 and the fourth side 04 may also have a recess 103.

[0115] For example, the lid 102 has recesses 103 on the first side 01, the second side 02, the third side 03, and the fourth side 04. In this case, the portion of the lid 102 between the first side 01 and the second side 02 may also have recesses 103, and the portion of the lid 102 between the third side 03 and the fourth side 04 may also have recesses 103.

[0116] In the first embodiment of this application, the more sides where the recessed portion 103 is located, the faster the pressure is released.

[0117] In some embodiments, such as Figure 7-9 As shown, the recess 103 may be provided with connecting members 105. In this case, in order to achieve quick separation of the cover 102 and the housing 101 at the recess 103, the number of connecting members 105 on the side where the recess 103 is located is less than the number of connecting members 105 on other sides. Here, "other sides" refers to the sides of the chassis 100 other than the side where the recess 103 is located.

[0118] For example, such as Figure 7 and Figure 8As shown, the number of connecting members 105 on the side where the recess 103 is located (first side 01 and second side 02) is one, and the number of connecting members 105 on the other sides (third side 03 and fourth side 04) is four; as Figure 9 As shown, the number of connecting members 105 on the side where the recess 103 is located (first side 01 and second side 02) is three, and the number of connecting members 105 on the other sides (third side 03 and fourth side 04) is four.

[0119] Of course, the number of connecting members 105 on the side where the recess 103 is located can be two or four or more, and the number of connecting members 105 on other sides can be three or five or more, as long as the number of connecting members 105 on the side where the recess 103 is located is less than the number of connecting members 105 on other sides.

[0120] In the above structure, the chassis 100 can form a weak connection area 106 at the recess 103, and a strong connection area 107 at other locations. Under the pressure in the receiving cavity 1010, the cover 102 and the body 101 quickly separate at the weak connection area 106, and the recess 103 quickly deforms and forms a pressure relief port 104 to release the explosive impact. At the same time, the cover 102 and the body 101 remain connected at the strong connection area 107, thereby preventing the cover 102 from flying off the body 101 under the strong explosive impact and improving the reliability of the power equipment.

[0121] In order to achieve rapid separation of the cover 102 and the housing 101 at the recess 103, the connection strength of the connecting member 105 on the side where the recess 103 is located is less than the connection strength of the connecting members 105 on other sides. Here, "other sides" refers to the sides of the housing 100 other than the side where the recess 103 is located; the connection strength of the connecting member 105 refers to the connection strength of a single connecting member 105.

[0122] In the above structure, the chassis 100 may also form a weak connection area 106 at the recess 103, and a strong connection area 107 at other locations. Under the pressure in the receiving cavity 1010, the cover 102 and the body 101 quickly separate in the weak connection area 106, and the recess 103 quickly deforms and forms a pressure relief port 104 to release the explosive impact. At the same time, the cover 102 and the body 101 remain connected in the strong connection area 107, thereby preventing the cover 102 from flying off the body 101 under the strong explosive impact and improving the reliability of the power equipment.

[0123] The connection strength of the connecting member 105 can be related to its own strength. For example, the greater the strength of the connecting member 105, the greater the connection strength; conversely, the smaller the strength of the connecting member 105, the smaller the connection strength. The diameter or other parameters characterizing the thickness of the connecting member 105 can affect its own strength, as can the material of the connecting member 105.

[0124] The connection strength of the connecting member 105 can also be related to other factors. For example, increasing the contact area between the connecting member 105 and either the cover 102 or the body 101 can increase the connection strength of the connecting member 105; decreasing the contact area between the connecting member 105 and either the cover 102 or the body 101 can decrease the connection strength of the connecting member 105. Adding a gasket between the connecting member 105 and either the cover 102 or the body 101 can also increase the connection strength of the connecting member 105.

[0125] For example, the connecting member 105 on the side where the recess 103 is located can be a common bolt, so as to form a weak connection area 106 on the connection side where the recess 103 is located, while the connecting member 105 on other sides can be a high-strength bolt, so as to form a strong connection area 107 on the other side.

[0126] For example, reinforcing members such as reinforcing pads can be provided on the connecting members 105 on other sides to improve the connection strength of the connecting members 105 on other sides. However, since no reinforcing members such as reinforcing pads are provided on the connecting members 105 on the side where the recess 103 is located, the strength of the connecting members 105 on the side where the recess 103 is located is less than the strength of the connecting members 105 on other sides.

[0127] The connecting member 105 on the side where the recess 103 is located and the connecting members 105 on other sides can be of the same or different types. For example, one type of connecting member 105 requires a matching mounting hole, and at least one of the cover 102 and the body 101 can be provided with a mounting hole to match the connecting member 105; another type of connecting member 105 does not require a matching mounting hole, that is, the cover 102 and the body 101 do not need to be provided with mounting holes.

[0128] When the recess 103 is provided with connecting members 105, the recess 103 is provided with at least two connecting members 105 with different connection strengths. The recess depth at the location of the connecting member 105 with higher connection strength is less than the recess depth at the location of the connecting member 105 with lower connection strength. In this way, under the pressure in the receiving cavity 1010, the recess 103 and the box 101 separate first at the connecting member 105 with lower connection strength, and the part of the recess 103 with a larger recess depth deforms first. The recess 103 and the box 101 separate later at the connecting member 105 with higher connection strength, and the part of the recess 103 with a smaller recess depth deforms later, achieving a staged pressure relief effect. At the same time, by adjusting the position of the connecting member 105 on the recess 103, the size of the pressure relief port 104 can also be adjusted.

[0129] For example, such as Figure 9 and Figure 10 As shown, the recessed portion 103 is provided with three connecting members 105: two connecting members 105a and one connecting member 105b. The connection strength of the first connecting member 105a is greater than that of the second connecting member 105b. The recess depth at the location of the first connecting member 105a is h1, and the recess depth at the location of the second connecting member 105b is h2, where h1 is less than h2. This ensures that a pressure relief port 104 can be quickly formed at the location of the second connecting member 105b, achieving the effect of releasing the explosive impact force. At the same time, the pressure relief port 104 can gradually expand towards the location of the first connecting member 105a, thereby forming a staged pressure relief effect.

[0130] The location of the second connecting member 105b can be the deepest point of the recess 103, where h2 is the maximum recess depth of the recess 103. Both the first side 01 and the second side 02 have recesses 103. The connection strength of the first connecting member 105a is less than the connection strength of the connecting member 105 on the third side 03 and also less than the connection strength of the connecting member 105 on the fourth side 04. The connection strength of the second connecting member 105b is less than the connection strength of the connecting member 105 on the third side 03 and also less than the connection strength of the connecting member 105 on the fourth side 04.

[0131] In practice, the recess 103 may also be provided with two, four or more connecting members 105, and satisfy the aforementioned condition that "at least two connecting members 105 at the recess 103 have different connection strengths, and the recess depth at the location of the connecting member 105 with higher connection strength is less than the recess depth at the location of the connecting member 105 with lower connection strength".

[0132] In practice, in order to achieve rapid separation of the lid 102 and the body 101 at the recess 103, the connection strength of the connecting member 105 on the side where the recess 103 is located is less than the connection strength of the connecting member 105 on the other side, and the connection strength of the connecting member 105 on the side where the recess 103 is located is less than the connection strength of the connecting member 105 on the other side.

[0133] In some other embodiments, the connecting member 105 is located in the portion of the chassis 100 other than the recess 103. When the cover 102 has a recess 103, the connecting member 105 is located in the portion of the cover 102 other than the recess 103. It is understood that the recess 103 is not provided with the connecting member 105. Thus, the area where the connecting member 105 is located forms a reinforced connection area 107, and the area where the recess 103 is located forms a weak connection area 106. Under the pressure within the receiving cavity 1010, the cover 102 and the chassis 101 quickly separate in the weak connection area 106, and the recess 103 quickly deforms and forms a pressure relief port 104 to release the explosive impact force. Simultaneously, the cover 102 and the chassis 101 remain connected in the reinforced connection area 107, thereby preventing the cover 102 from flying off the chassis 101 under the powerful explosive impact force and improving the reliability of the power equipment.

[0134] like Figure 10 As shown, the connecting member 105 can sequentially connect the box body 101 and the box cover 102. This can be understood as the connecting member 105 connecting the box body 101 first and then the box cover 102. In this way, the connecting member 105 is installed from the side of the box body 101 away from the box cover 102 towards the box body 101. At the moment of explosion, the connecting member 105 detaches from the box cover 102. The connecting member 105 remains on the box body 101, or it falls under its own weight, thus preventing the connecting member 105 from being blown away.

[0135] When the connecting member 105 is a threaded connector, the head of the connecting member 105 is located on the side of the housing 101 away from the cover 102.

[0136] In practice, such as Figure 1 and Figure 4 As shown, the connecting member 105 can also connect the cover 102 and the body 101 sequentially. This can be understood as the connecting member 105 connecting the cover 102 first and then the body 101. In this way, the connecting member 105 is installed with the side of the cover 102 facing away from the body 101. When the connecting member 105 is a threaded connector, the head of the connecting member 105 is located on the side of the cover 102 facing away from the body 101. Figure 7-9 It is also shown that the connecting member 105 connects the cover 102 and the box body 101 in sequence.

[0137] certainly,Figure 1 , Figure 4 and Figure 7-9 In the structure shown, the connecting member 105 can connect the box body 101 and the box cover 102 in sequence, and is not limited to the structure shown.

[0138] like Figure 11-14 As shown, the recessed portion 103 is provided with a groove 1031, and there is a preset distance between the connection between the housing 101 and the cover 102 and the groove 1031. It can be understood that the preset distance is greater than zero. In this way, the groove 1031 avoids the connection between the housing 101 and the cover 102, thereby reducing the impact on the connection between the housing 101 and the cover 102, and also reducing the impact on the sealing performance of the chassis. At the same time, the groove 1031 can weaken the strength of the recessed portion 103, thereby facilitating the deformation of the recessed portion 103 under the pressure within the receiving cavity 1010, and thus accelerating the deformation of the recessed portion 103 under the pressure within the receiving cavity 1010. To improve the appearance of the chassis 100, the opening of the groove 1031 can face the receiving cavity 1010. Of course, the opening of the groove 1031 can also face away from the receiving cavity 1010.

[0139] The groove 1031 can be one or more. To effectively reduce the strength of the recess 103, the groove 1031 can have at least two. For example... Figure 12 and Figure 13 As shown, all the grooves 1031 are distributed along the curvature of the recess 103, and all the grooves 1031 can form a serrated structure 109. In this way, the distribution direction of the grooves 1031 is consistent with the curvature of the recess 103, which further facilitates the deformation of the recess 103.

[0140] The shape of the groove 1031 is selected according to the actual situation. For example, such as... Figure 12 As shown, groove 1031 is triangular; as Figure 13 As shown, the groove 1031 is rectangular. Of course, the groove 1031 can also be trapezoidal or other shapes, and this embodiment of the application does not limit it.

[0141] like Figure 11 and Figure 14As shown, to facilitate the recess 1031 avoiding the connection between the box body 101 and the box cover 102, the box cover 102 includes a box cover body 1022 and a box cover flange 1023. The box cover flange 1023 is connected to the periphery of the box cover body 1022, and the box cover flange 1023 is located on the side of the box cover body 1022 closer to the box body 101. The box cover body 1022 and the box body 101 are connected. The recess 103 is located between the box cover body 1022 and the box cover flange 1023, and the recess 1031 is provided in the portion of the recess 103 located on the box cover flange 1023. Since the box cover flange 1023 and the box body 101 are not directly connected, the recess 1031 avoids the connection between the box body 101 and the box cover 102.

[0142] In the above structure, the recessed portion 103 located on the flange 1023 of the lid can be entirely provided with a groove 1031, or the recessed portion 103 located on the flange 1023 of the lid can be partially provided with a groove 1031.

[0143] In the lid 102, the shape of the groove 1031 can be one or more, and this application embodiment does not limit this.

[0144] In practice, the groove 1031 can also be set on the body of the box cover 1022, as long as the groove 1031 avoids the connection between the box body 101 and the box cover 102.

[0145] In the event of pressure relief, components or foreign objects within the housing 1010 are more likely to be ejected from the pressure relief port 104, potentially leading to a safety accident. To improve safety and reliability, such as... Figure 15 As shown, the recessed portion 103 is provided with a shield 108, which is used to shield at least a portion of the pressure relief port 104, and the shield 108 is provided with a pressure relief hole 1081. In this way, while ensuring normal pressure relief, it also prevents the devices or foreign objects in the receiving cavity 1010 from flying out of the receiving cavity 1010, thereby improving safety and reliability. At the same time, the shield 108 also serves to prevent finger touch.

[0146] For example, such as Figure 15 As shown, the shield 108 can block a portion of the pressure relief port 104. For example... Figure 18 As shown, the shield 108 can block the entire pressure relief port 104.

[0147] In order to reduce the impact of the shielding component 108 on the pressure relief port 104, the shielding component 108 has multiple pressure relief holes 1081, which are arranged in an array and uniformly to achieve the effect of uniformly releasing the explosive force.

[0148] like Figure 15As shown, the pressure relief hole 1081 can be an oblong hole, and the length direction of each oblong hole is consistent. Of course, the pressure relief hole 1081 can also be a circular hole, a triangular hole, a rectangular hole, or other shapes. This embodiment of the application does not limit it, as long as it ensures that the device or foreign object in the receiving cavity 1010 will not fly out from the pressure relief hole 1081.

[0149] The shield 108 can be located inside or outside the receiving cavity 1010. In order to improve the aesthetics of the chassis 100, the shield 108 can be located inside the receiving cavity 1010.

[0150] In Embodiment 1 of this application, the shielding member 108 can be a rigid member or a flexible member. For example... Figure 13 and Figure 14 As shown, when the blocking member 108 is a rigid member, the blocking member 108 may include a blocking plate 108a. For example... Figure 17 and Figure 18 As shown, when the shielding member 108 is a flexible member, it may include a shielding mesh 108b. The shielding mesh 108b may be a metal mesh, plastic mesh, fabric mesh, or a mesh made of other materials. The shielding plate 108a may be a metal plate, plastic plate, or a plate made of other materials.

[0151] In practice, the shielding member 108 may also include a shielding plate 108a and a shielding net 108b, wherein the shielding plate 108a and the shielding net 108b are connected, and the shielding plate 108a and the shielding net 108b are distributed along the moving direction of the shielding member 108, or the shielding plate 108a and the shielding net 108b are distributed along the thickness direction of the shielding plate 108a.

[0152] In some embodiments, one end of the shielding member 108 is connected to the recess 103, and the other end of the shielding member 108 is suspended. Thus, when the recess 103 deforms, the shielding member 108 moves with the deformation of the recess 103. It can be understood that the shielding member 108 can move away from the housing 101 under the action of the cover 102, so that the shielding member 108 can block at least a portion of the pressure relief port 104. Under normal operating conditions of the electrical equipment, the shielding member 108 is hidden within the receiving cavity 1010, ensuring the aesthetics of the chassis 100.

[0153] In the above embodiments, the shielding member 108 may include at least one of the shielding plate 108a and the shielding net 108b.

[0154] In some other embodiments, one end of the shielding member 108 is connected to the recess 103, and the other end of the shielding member 108 is movably connected to the cover 102 or the housing 101. For example, one end of the shielding member 108 is fixedly connected to the cover 102, the other end of the shielding member 108 is away from the cover 102, and the other end of the shielding member 108 can be movably connected to the side wall of the housing 101. Thus, when the recess 103 deforms, the shielding member 108 moves with the deformation of the recess 103. It can be understood that the shielding member 108 can move away from the housing 101 under the influence of the cover 102, so that the shielding member 108 can block at least a portion of the pressure relief port 104. When the power equipment is operating normally, the shielding member 108 is hidden inside the receiving cavity 1010, ensuring the aesthetics of the chassis 100.

[0155] In the above embodiments, the shielding member 108 may include a shielding plate 108a, or the shielding member 108 may include a shielding plate 108a and a shielding net 108b.

[0156] To enable the end of the shielding member 108 away from the cover 102 to be movably connected to the side wall of the housing 101, for example, a slider is provided at the end of the shielding member 108 connected to the side wall of the housing 101. A guide rail is fixed on the side wall of the housing 101, and the length direction of the guide rail is consistent with the deformation direction of the recess 103. The slider and the guide rail slide together along the length direction of the guide rail. During the process of the recess 103 deforming to form the pressure relief port 104, the slider slides along the length direction of the guide rail, and the shielding member 108 moves away from the housing 101 under the action of the cover 102, so that the shielding member 108 blocks part of the pressure relief port 104.

[0157] In some other embodiments, one end of the shield 108 is connected to the recess 103, and the other end of the shield 108 is connected to the cover 102 or the box body 101. The shield 108 has a contracted state and an extended state. Under the deformation of the recess 103, the shield 108 switches from the contracted state to the extended state.

[0158] In the above embodiments, the shielding member 108 may include at least one of the shielding plate 108a and the shielding net 108b.

[0159] When the blocking member 108 includes a blocking plate 108a, in order to ensure that the blocking member 108 has a retracted state and an extended state, such as Figure 16As shown, the baffle 108a includes a first baffle 1082 and a second baffle 1083. The first baffle 1082 and the second baffle 1083 are slidably engaged. One end of the first baffle 1082 is connected to the recess 103, and the other end of the first baffle 1082 is connected to one end of the second baffle 1083. The other end of the second baffle 1083 is suspended, or the other end of the second baffle 1083 is connected to either the housing 101 or the lid 102.

[0160] Example 2 of this application

[0161] like Figure 22 and Figure 23 As shown, the chassis 100 provided in Embodiment 2 of this application includes: a chassis 101 and a cover 102. The chassis 101 has an opening, and the cover 102 is connected to the chassis 101. The cover 102 closes the opening of the chassis 101 and restricts the cavity 1010 for accommodating electronic devices.

[0162] It should be noted that, Figure 22 In order to show the receiving cavity 1010, part of the box 101 is hidden, and the area enclosed by the dotted line represents the hidden part.

[0163] In the second embodiment of this application, the box body 101 has a recessed portion 103, which is recessed from the outside of the receiving cavity 1010 to the inside of the receiving cavity 1010, and part of the recessed portion 103 is located at the connection between the box body 101 and the box cover 102.

[0164] like Figure 24 and Figure 25 As shown, the recessed portion 103 can deform towards the side away from the receiving cavity 1010 under the pressure within the receiving cavity 1010, forming a pressure relief port 104. Thus, when the pressure within the receiving cavity 1010 reaches a pressure value that causes the recessed portion 103 to deform, for example, when the pressure within the receiving cavity 1010 reaches a set threshold, the recessed portion 103 deforms towards the side away from the receiving cavity 1010 under the pressure within the receiving cavity 1010. During the deformation of the recessed portion 103, the external force generated by the pressure within the receiving cavity 1010, such as the external force generated by an explosion within the receiving cavity 1010, is effectively attenuated, reducing the pressure exerted by the lid 102 within the receiving cavity 1010. The probability of the cover 102 flying off the housing 101 is reduced, thus improving the reliability of the power equipment. At the same time, part of the recess 103 is located at the connection between the housing 101 and the cover 102. As the recess 103 deforms, it forms a pressure relief port 104, which achieves the function of pressure relief, such as relieving the impact force of an explosion. This reduces the probability of the cover 102 flying off the housing 101 under the pressure in the receiving cavity 1010, and can even prevent the cover 102 from flying off the housing 101 under the pressure in the receiving cavity 1010, thereby improving the reliability of the power equipment.

[0165] There may be one, two, three, or more recesses 103. When there are at least two recesses 103, the at least two recesses 103 are located on the same side of the housing 101; or, the at least two recesses 103 are located on different sides of the housing 101; or, the at least two recesses 103 are located on the same side of the housing 101 and at least two recesses 103 are located on different sides of the housing 101, in which case there are at least three recesses 103.

[0166] For example, such as Figure 22 and Figure 23 As shown, there are two recesses 103. One recess 103 is located on the first side 01 of the box 101, and the other recess 103 is located on the second side 02 of the box 101, so that the two recesses 103 are located on different sides of the box 101.

[0167] like Figure 26 and Figure 27 As shown, there are three recesses 103. One recess 103 is located on the first side 01 of the box 101, another recess 103 is located on the second side 02 of the box 101, and another recess 103 is located on the third side 03 of the box 101, so that the three recesses 103 are located on different sides of the box 101.

[0168] like Figure 30 and Figure 31 As shown, there are four recesses 103. One recess 103 is located on the first side 01 of the box 101, another recess 103 is located on the second side 02 of the box 101, another recess 103 is located on the third side 03 of the box 101, and another recess 103 is located on the fourth side 04 of the box 101, thus realizing that the four recesses 103 are located on different sides of the box 101.

[0169] For a description of the first side 01, the second side 02, the third side 03 and the fourth side 04 mentioned above, please refer to Embodiment 1 of this application, which will be repeated here.

[0170] like Figure 22As shown, the enclosure 101 has a recess 103, and the cover 102 has a recess 1021. At least a portion of the projection of the recess 1021 along a first direction is located within the recess 103, where the first direction is the distribution direction of the enclosure 101 and the cover 102. For example, a portion of the projection of the recess 1021 along the first direction is located within the recess 103; or the projection of the recess 1021 along the first direction is completely located within the recess 103. Thus, as the recess 103 deforms, the projection of the recess 1021 along the first direction is no longer located within the deformed recess 103, allowing a pressure relief port 104 to be quickly formed between the deformed recess 103 and the recess 1021. This facilitates faster pressure relief and improves the safety and reliability of the power equipment. Simultaneously, the recess 1021 in the cover 102 reduces the volume of the cover 102, thereby lowering the cost of the enclosure 100.

[0171] In practice, the cover 102 may not have the recess 1021, and is not limited to the above structure.

[0172] In the second embodiment of this application, the lid 102 and the body 101 are connected by connecting members 105 on at least two sides of the first side 01, the second side 02, the third side 03 and the fourth side 04.

[0173] For example, such as Figure 22 and Figure 23 As shown, connecting members 105 are located at the four corners of the cover 102 and the four corners of the housing 101, such that the cover 102 and the housing 101 are connected via the connecting members 105 on the first side 01, the second side 02, the third side 03, and the fourth side 04. The area where the connecting members 105 are located forms a connection reinforcement area 107, and other areas in the housing 100 within the area where the connecting members 105 are located form connection weakness areas 106. There are four connecting members 105 and four connection weakness areas 106.

[0174] Of course, the lid 102 and the body 101 can also be connected by connecting members 105 on at least two other sides, as detailed in Embodiment 1 of this application.

[0175] In the second embodiment of this application, the chassis 100 has a recess 103 on at least one of the first side 01, the second side 02, the third side 03 and the fourth side 04.

[0176] For example, the chassis 100 has a recess 103 on one of the first side 01, the second side 02, the third side 03 and the fourth side 04.

[0177] For example, the chassis 100 has recesses 103 on both sides of the first side 01, the second side 02, the third side 03, and the fourth side 04. Figure 22 and Figure 23As shown, there are two recesses 103. One recess 103 can be located on the first side 01 of the housing 101, and the other recess 103 can be located on the second side 02 of the housing 101; as Figure 24 and Figure 25 As shown, after the recess is deformed, a pressure relief port 104 is formed. There are two pressure relief ports 104, which are located on the first side 01 and the second side 02 of the housing 101, respectively.

[0178] Of course, one recess 103 may be located on the third side 03 of the housing 101, and the other recess 103 may be located on the fourth side 04 of the housing 101; or one recess 103 may be located on the first side 01 of the housing 101, and the other recess 103 may be located on the third side 03 of the housing 101; or one recess 103 may be located on the first side 01 of the housing 101, and the other recess 103 may be located on the fourth side 04 of the housing 101; or one recess 103 may be located on the second side 02 of the housing 101, and the other recess 103 may be located on the fourth side 04 of the housing 101; or one recess 103 may be located on the second side 02 of the housing 101, and the other recess 103 may be located on the third side 03 of the housing 101.

[0179] For example, the chassis 100 has recesses 103 on three of the first side 01, the second side 02, the third side 03, and the fourth side 04. Figure 26 and Figure 27 As shown, there are three recesses 103. One recess 103 can be located on the first side 01 of the housing 101, another recess 103 can be located on the second side 02 of the housing 101, and another recess 103 can be located on the third side 03 of the housing 101; as shown Figure 28 and Figure 29 As shown, the recessed portion deforms to form a pressure relief port 104. There are three pressure relief ports 104, which are located on the first side 01, the second side 02, and the third side 03 of the housing 101, respectively. Of course, the three recessed portions 103 can also be located on the first side 01, the second side 02, and the fourth side 04, respectively; or, the three recessed portions 103 can also be located on the third side 03, the fourth side 04, and the first side 01, respectively; or, the three recessed portions 103 can also be located on the third side 03, the fourth side 04, and the second side 02, respectively.

[0180] For example, the chassis 100 has recesses 103 on the first side 01, the second side 02, the third side 03, and the fourth side 04. Figure 30 and Figure 31 As shown, there are four recesses 103: one recess 103 is located on the first side 01, another recess 103 is located on the second side 02, another recess 103 is located on the third side 03, and another recess 103 is located on the fourth side 04; as Figure 32 and Figure 33As shown, after the recess is deformed, it forms a pressure relief port 104. There are four pressure relief ports 104, which are located on the first side 01, the second side 02, the third side 03 and the fourth side 04 of the housing 101, respectively.

[0181] In the second embodiment of this application, the recessed portion 103 may or may not have a connecting member 105. For example, Figure 22 and Figure 23 As shown, the recessed portion 103 may not be provided with the connecting member 105. For a detailed description of this part, please refer to Embodiment 1 of this application.

[0182] It should be noted that the recess 103 is located in the weak connection area 106 mentioned above, which can also be understood as: at least one of the four weak connection areas 106 has a recess 103.

[0183] When a connecting member 105 is provided in the recess 103, in order to facilitate the quick separation of the lid 102 and the body 101 at the recess 103, the connection strength of the connecting member 105 on the side where the recess 103 is located is less than the connection strength of the connecting members 105 on other sides; or, the connection strength of the connecting member 105 on the side where the recess 103 is located is less than the connection strength of the connecting members 105 on other sides; or, the connection strength of the connecting member 105 on the side where the recess 103 is located is less than the connection strength of the connecting members 105 on other sides. For a detailed description of this part, please refer to Embodiment 1 of this application.

[0184] In Embodiment 2 of this application, the connecting member 105 can sequentially connect the box body 101 and the box cover 102, or the connecting member 105 can sequentially connect the box cover 102 and the box body 101. For a detailed description of this part, please refer to Embodiment 1 of this application.

[0185] In Embodiment 2 of this application, the recessed portion 103 is provided with a shielding member. Since the recessed portion 103 is located in the housing 101, the shielding member is also located in the housing 101. The shielding member is used to shield at least a portion of the pressure relief port 104, and the shielding member is provided with a pressure relief hole. In this way, while ensuring normal pressure relief, it also prevents components or foreign objects in the receiving cavity from flying out of the receiving cavity, thereby improving safety and reliability; at the same time, the baffle also serves to prevent finger contact. For a detailed description of the shielding member, please refer to Embodiment 1 of this application.

[0186] In Embodiment 2 of this application, as Figure 35 and Figure 36As shown, the recessed portion 103 may be provided with a groove 1031. A predetermined distance is maintained between the connection point of the housing 101 and the cover 102 and the groove 1031. For a detailed description of this part, please refer to Embodiment 1 of this application.

[0187] like Figure 34 As shown, the box body 101 includes a box body 1012 and a first box body flange 1013. The first box body flange 1013 is connected to the periphery of the box body 1012 and is located outside the box body 1012. The first box body flange 1013 is connected to the box lid. A recessed portion 103 is located between the box body 1012 and the first box body flange 1013. A groove 1031 is provided in the recessed portion 103 at the connection between the first box body flange 1013 and the box body 1012. It can be understood that a groove 1031 is provided at the connection between the first box body flange 1013 and the box body 1012.

[0188] In the above structure, since the first box body flange 1013 is connected to the box cover 102, the recessed part 103 located on the first box body flange 1013 can be partially provided with a groove 1031.

[0189] like Figure 36 As shown, the groove opening of the groove 1031 faces... Figure 3 On the right side, the depth direction of the groove 1031 is consistent with the wall thickness direction of the main body 1012, and the depth of the groove 1031 is less than the wall thickness of the main body 1012. This makes it easier to ensure the strength of the first box flange 1013, as well as the integrity of the box 101 and the sealing performance of the chassis 100.

[0190] In the above structure, a sealing element can be provided between the first housing flange 1013 and the housing cover 102, which can improve the sealing performance of the housing 100.

[0191] In the housing 101, the shape of the groove 1031 can be one or more, and this application embodiment does not limit this.

[0192] In practice, the groove 1031 can also be set on the main body 1012 of the box.

[0193] Continue to refer to Figure 34 The box body 101 may also include a second box body flange 1014, which is connected to the first box body flange 1013. The second box body flange 1014 is located on the side of the box body 1012 near the lid, and supports the lid body. The second box body flange 1014 can also be connected to the lid body. In this case, the recess 103 of the box body 101 is also located on the second box body flange 1014.

[0194] In Embodiment 2 of this application, the structure of the box 101 itself (the box 101 includes the box body 1012 and the first box flange 1013, or the box 101 includes the box body 1012, the first box flange 1013 and the second box flange 1014) can also be applied to Embodiment 1 of this application.

[0195] For other descriptions of the chassis 100 in Embodiment 2 of this application, please refer to Embodiment 1 of this application, and they will not be repeated here.

[0196] In practice, Embodiment 1 and Embodiment 2 of this application can be combined, and can be understood as follows: both the lid 102 and the body 101 have recesses 103.

[0197] Based on the chassis provided in the above embodiments, this application also discloses a power device, which includes the chassis disclosed in the above embodiments. Therefore, the power device has all the technical effects of the chassis described above, and will not be repeated here.

[0198] For example, power equipment can be power conversion devices with enclosed chambers, such as inverters, energy storage converters, and rectifiers, or other equipment.

[0199] The technical features mentioned above, as well as those shown individually in the accompanying drawings, can be combined arbitrarily, provided that the combined technical features are not contradictory. All feasible combinations of features are those explicitly described herein.

[0200] The above description of the disclosed embodiments enables those skilled in the art to make or use this application.
