Description

Technical Field

[0001] This application relates to the field of power equipment protection technology, and more specifically, to a chassis, power equipment, and power system. Background Technology

[0002] In electrical equipment, electronic components are typically housed in a sealed enclosure. When these components abnormally generate gas, the enclosure's airtight design prevents the accumulated pressure from escaping. If the pressure inside the enclosure increases to a certain level, it can rupture under immense pressure, creating a large opening that exposes the internal electronic components, posing a significant safety hazard.

[0003] Therefore, how to improve the safety performance of power equipment has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0019] The third protective body is a cover disposed in the outer casing; or, the third protective body is a shell disposed in the outer casing and shields the first type of electronic components in the first direction.

[0020] In some embodiments, the protective element is a protective cover that covers the outside of the first type of electronic component and is disposed within the housing of the outer casing.

[0021] In some embodiments, the protective element is a conductive element, and the protective element and the housing are electrically connected to form a closed circuit; or, the protective element is an insulating element.

[0022] In some embodiments, the protective member is provided with at least one of a protrusion and a recess; the protrusion protrudes toward the side of the protective member away from the first type of electronic component; the recess is recessed toward the side of the protective member closer to the first type of electronic component.

[0023] In some embodiments, the protective member is disposed outside the housing, the width direction of the gap is parallel to the axial direction of the explosion vent, and the projection of the protective member on the axial direction of the explosion vent covers the explosion vent.

[0024] In some embodiments, the width direction of the gap is the distribution direction of the protective member, the gap, and the outer shell, and the length direction of the gap is perpendicular to the width direction of the gap;

[0025] Along the length of the gap, at least one end of the gap has a gap opening, and the minimum width of the gap is not greater than a set width.

[0026] In some embodiments, the set width ranges from 12mm to 50mm.

[0027] In some embodiments, the protective member is provided with a vent hole, and the vent hole is connected to the gap.

[0028] In some embodiments, the protective element is configured to correspond one-to-one with the explosion vent, or multiple protective elements are configured to correspond to one explosion vent.

[0038] Based on the power equipment provided above, this application also provides a power system, which includes the aforementioned power equipment.

[0039] In the chassis provided in this application embodiment, the explosion vent is configured to form an explosion vent opening. The protective component is connected to the outer shell, and the protective component and the outer shell form an anti-touch channel. The anti-touch channel includes the explosion vent opening and blocks the passage of designated components outside the outer shell, so that the designated components outside the outer shell cannot pass through the anti-touch channel. Since the first type of electronic components inside the outer shell are located outside the anti-touch channel, the anti-touch channel can prevent the designated components outside the outer shell from accidentally touching the first type of electronic components inside the outer shell, reducing the probability of the designated components outside the outer shell accidentally touching the first type of electronic components inside the outer shell, reducing the safety hazards caused by chassis explosion, thereby reducing the safety hazards of power equipment and improving the safety performance of power equipment.

[0040] In the chassis provided in this application embodiment, the first type of electronic components are configured such that the minimum distance between them and the explosion vent is not less than a set distance. This allows the first type of electronic components to be kept away from the explosion vent and the explosion vent. Because the length of the set component outside the casing is limited, the probability of the set component outside the casing accidentally touching the first type of electronic components inside the casing through the explosion vent is reduced. This reduces the safety hazards caused by chassis explosion, thereby reducing the safety hazards of electrical equipment and improving the safety performance of electrical equipment.

[0041] As can be seen from the above, the chassis provided in this application embodiment reduces the probability of the outer casing accidentally touching the first type of electronic components inside the chassis, reduces the safety hazards caused by chassis explosion, thereby reducing the safety hazards of power equipment and improving the safety performance of power equipment.

Detailed Implementation

[0070] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0071] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise. It should also be understood that in the embodiments of this application, “one or more” means one, two, or more; “and / or” describes the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character “ / ” generally indicates that the preceding and following related objects are in an “or” relationship.

[0072] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0073] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0074] The terms "parallel" and "perpendicular" used in this application refer to "basically parallel" and "basically perpendicular" in practical operation. "Basically parallel" can be understood as parallelism with a certain degree of error, and similarly, "basically perpendicular" can be understood as perpendicularity with a certain degree of error.

[0075] In related technologies, electrical equipment enclosures house electronic components. When these components malfunction, they can generate gas. Due to the enclosure's airtight design, the accumulated pressure has nowhere to release. If the pressure inside the enclosure increases to a certain level, it can rupture under immense pressure, for example, by opening the explosion vent. This creates a large opening in the enclosure, exposing internal electronic components, such as high-voltage components. Hands, conductive tools, or other conductive objects may come into contact with these exposed components, easily leading to injury and posing a significant safety hazard.

[0076] In view of the above problems, this application provides a chassis, power equipment and power system to reduce the safety hazards of power equipment and improve the safety performance of power equipment.

[0077] like Figure 1 As shown in the embodiment of this application, the chassis includes an outer shell 100.

[0078] The housing 100 houses a first-type electronic component 300. Exemplarily, the housing 100 defines a receiving cavity 101, which houses the first-type electronic component 300. The first-type electronic component 300 can be a high-voltage component, or it can include both high-voltage and low-voltage components. To reduce protection costs, the first-type electronic component 300 can be a high-voltage component.

[0079] In practice, the housing 100 also houses a second type of electronic component 400, which may include low-voltage components.

[0080] In this application embodiment, "high-voltage" and "low-voltage" are relative concepts. For example, AC voltage greater than 36V (human safety voltage) is defined as high-voltage, DC voltage greater than 24V is defined as high-voltage, AC voltage below 36V (human safety voltage) (including 36V) is defined as low-voltage, and DC voltage below 24V (including 24V) is defined as low-voltage. For example, high-voltage electricity deals with energy (electricity), characterized by high voltage, high current, high power, and low frequency; low-voltage electricity deals with information, i.e., information transmission and control, characterized by low voltage, low current, low power, and high frequency.

[0081] Continue to refer to Figure 1 The outer casing 100 includes: a casing 103 and a cover 104 covering the casing 103.

[0082] The housing 103 has a housing opening 1031, and the cover 104 closes the housing opening 1031, so that the housing 103 and the cover 104 cooperate to restrict the receiving cavity 101. It can be understood that the housing 103 restricts a part of the receiving cavity 101, and the cover 104 restricts another part of the receiving cavity 101.

[0083] The cover 104 and the shell 103 can be fixedly connected by bolts or other fasteners or other components, but this application embodiment does not limit this.

[0084] In the outer casing 100, the distribution direction of the shell 103 and the cover 104 can be a first direction, which can be a vertical direction.

[0085] The outer casing 100 is provided with a pressure relief section 102, which is configured to form a pressure relief opening 1021. Thus, when the outer casing 100 needs to release pressure or withstand an explosion, for example when the pressure inside the outer casing 100 reaches a set pressure, the pressure relief section 102 forms the pressure relief opening 1021, and the pressure inside the outer casing 100 is released to the outside of the outer casing 100 through the pressure relief opening 1021. The specific value of the set pressure is set according to the actual situation, and this embodiment does not limit it.

[0086] The housing 100 has multiple sides. For example, the housing 100 has two sides in a first direction, two sides in a second direction, and two sides in a third direction. Both the second and third directions are perpendicular to the first direction, and the second direction is perpendicular to the third direction. In the housing 100, the side where the explosion vent 102 is located can be referred to as the explosion vent side 108.

[0087] The explosion vent 102 can be located at the junction 102a of the cover 104 and the housing 103. Exemplarily, the explosion vent 102 can be located at all positions of the junction 102a. When the housing 100 needs to release pressure and vent an explosion, the cover 104 and the housing 103 separate at all positions of the junction 102a, which can be understood as the cover 104 and the housing 103 being completely separated. In this case, the explosion vent 1021 is the housing opening 1031 of the housing 103. There is only one explosion vent 1021. The explosion vent side 108 includes both sides of the housing 100 in the second direction and both sides of the housing 100 in the third direction.

[0088] Please refer to Figure 5a The explosion vent 102 may also be located at a portion of the joint 102a. When the housing 100 requires pressure relief and explosion venting, the joint 102a between the cover 104 and the housing 103 can be separated. This can be understood as: a portion of the cover 104 is connected to a portion of the housing 103, and a portion of the cover 104 is separated from a portion of the housing 103. For example, the connection strength between the cover 104 and the housing 103 at the explosion vent 102 is less than the connection strength at other joint locations.

[0089] like Figure 5a As shown, the explosion vent 102 is located on both sides of the housing 100 in the second direction, and correspondingly, the explosion vent side 108 includes both sides of the housing 100 in the second direction. In this case, there can be two explosion vent openings 1021.

[0090] Of course, the explosion vent 102 can be located on one side of the housing 100 in the second direction, and correspondingly, the explosion vent side 108 includes one side of the housing 100 in the second direction. In this case, there can be one explosion vent opening 1021.

[0091] like Figure 5b As shown, the explosion vent 102 can also be located on both sides of the housing 100 in the third direction, and correspondingly, the explosion vent side 108 includes both sides of the housing 100 in the third direction. In this case, there can be two explosion vent openings 1021.

[0092] Of course, the explosion vent 102 can also be located on the third-party upward side of the housing 100, and correspondingly, the explosion vent side 108 includes the third-party upward side of the housing 100. In this case, there can be one explosion vent opening 1021.

[0093] In practice, the explosion vent 102 is also located on both sides of the housing 100 in the second direction and on one side of the housing 100 in the third direction. Correspondingly, the explosion vent side 108 includes both sides of the housing 100 in the second direction and the side of the housing in the third direction. In this case, there can be three explosion vent openings 1021.

[0094] In practice, the explosion vent 102 is also located on both sides of the housing 100 in the third direction and on one side of the housing 100 in the second direction. Correspondingly, the explosion vent side 108 includes both sides of the housing 100 in the third direction and one side of the housing in the second direction. In this case, there can be three explosion vent openings 1021.

[0095] In this embodiment, the explosion vent 102 may also be located in other positions and have other structures. Please refer to... Figure 10 The explosion vent 102 is located on the housing 103. The explosion vent 102 includes an explosion vent structure 102b. The explosion vent 1021b of the explosion vent structure 102b is configured to form an explosion vent opening 1021. Thus, when the housing 100 needs to release pressure and vent an explosion, the explosion vent 1021b of the explosion vent structure 102b opens and forms the aforementioned explosion vent opening 1021. In this case, there can be only one explosion vent opening 1021; the explosion vent side 108 can be one side of the housing 100 in the second direction. Of course, the explosion vent side 108 can also be one side of the housing 100 in the third direction.

[0096] In practice, the explosion venting structure 102b can also be provided on the cover 104. In this case, there can be one explosion venting opening 1021; the explosion venting side 108 can be one side of the outer shell 100 in the first direction.

[0097] The explosion relief structure 102b can be an explosion relief valve, a part of the housing 103 with low local strength, or a part of the cover 104 with low local strength. The specific type of the explosion relief structure 102b is not limited in the embodiments of this application.

[0098] To reduce safety hazards of electrical equipment, this application provides three types of structures.

[0099] The first type of structure is described below.

[0100] Continue to refer to Figure 1The chassis also includes a protective component 200, which is connected to the outer casing 100. The outer casing 100 and the protective component 200 form an anti-touch channel 01. The anti-touch channel 01 is configured to include an explosion vent 1021. The anti-touch channel 01 is configured to block the passage of a designated component 600 outside the outer casing 100. This can be understood as: the anti-touch channel 01 is configured to block the passage of the designated component 600 outside the outer casing 100 through the anti-touch channel 01 itself. The first type of electronic component 300 is located outside the anti-touch channel 01.

[0101] The setting component 600 can be a hand, a finger, a finger-shaped conductive element, or a hand-shaped conductive element. The finger-shaped conductive element can be an accessibility test probe 600a or other finger-like conductive element, while the hand-shaped conductive element can be a robotic hand or other type of hand-shaped conductive element. The aforementioned second type of electronic component 400 can be located inside or outside the contactless channel 01.

[0102] The anti-touch channel 01 is configured to block the setting component 600 outside the housing 100 from passing through the anti-touch channel 01 itself. This can be understood as: the anti-touch channel 01 is configured to block the setting component 600 outside the housing 100 from entering the anti-touch channel 01; it can also be understood as: the anti-touch channel 01 is configured to block the setting component 600 outside the housing 100 from moving out of the anti-touch channel 01; it can also be understood as: the anti-touch channel 01 is configured to block the setting component 600 outside the housing 100 from entering the anti-touch channel 01 and from moving out of the anti-touch channel 01.

[0103] It should be noted that, Figure 1 and Figure 2 In order to display the receiving cavity 101, the first type of electronic component 300 and the second type of electronic component 400, part of the protective component 200 is hidden. Figure 1 and Figure 2 In the middle, the notch portion opposite to the protective component 200 and the first type of electronic component 300 and the second type of electronic component 400 is a hidden part.

[0104] In the chassis provided in this application embodiment, the protective component 200 is connected to the outer shell 100, and the protective component 200 and the outer shell 100 form an anti-touch channel 01 including an explosion vent opening 1021. The anti-touch channel 01 can prevent the setting component 600 outside the outer shell 100 from passing through the anti-touch channel 01. Since the first type of electronic component 300 inside the outer shell 100 is located outside the anti-touch channel 01, the anti-touch channel 01 can prevent the setting component 600 outside the outer shell 100 from accidentally touching the first type of electronic component 300 inside the outer shell 100, thereby reducing the probability of the setting component 600 outside the outer shell 100 accidentally touching the first type of electronic component 300 inside the outer shell 100, thereby reducing the safety hazards caused by chassis explosion, reducing the safety hazards of electrical equipment, and improving the safety performance of electrical equipment.

[0105] It should be noted that when the chassis needs to release pressure and withstand explosions, the chassis can release the explosion through the explosion vent 1021.

[0106] The second type of structure will be explained below.

[0107] Please refer to Figure 20 In the chassis, the first type of electronic component 300 is configured such that the minimum distance between it and the explosion vent 1021 is not less than a set distance. This allows the first type of electronic component 300 to be kept away from the explosion vent 102 and the explosion vent 1021. Because the length of the setting component 600 outside the housing 100 is limited, the probability of the setting component 600 outside the housing 100 accidentally touching the first type of electronic component 300 inside the housing 100 through the explosion vent 1021 is reduced. This reduces the safety hazards caused by chassis explosion, thereby reducing the safety hazards of electrical equipment and improving the safety performance of electrical equipment.

[0108] The first and second types of structures can be implemented individually or in combination. The combination of the first and second types of structures forms the third type of structure.

[0109] The third type of structure will be explained below.

[0110] The chassis also includes a protective component 200 connected to the outer casing 100. The outer casing 100 and the protective component 200 form an anti-touch channel 01. The anti-touch channel 01 is configured to include an explosion vent opening 1021 and block the passage of a designated component 600 outside the outer casing 100. A first type of electronic component 300 is located outside the anti-touch channel 01, and the minimum distance between the first type of electronic component 300 and the explosion vent 102 is not less than a set distance. This further reduces the probability that the designated component 600 outside the outer casing 100 will accidentally touch the first type of electronic component 300 inside the outer casing 100 through the explosion vent opening 1021.

[0111] It should be noted that in the first type of chassis structure, the minimum distance between the first type of electronic components 300 and the explosion venting part 102 may be less than a set distance or not less than a set distance; or, the minimum distance between some electronic components of the first type of electronic components 300 and the explosion venting part 102 may be less than a set distance, and the minimum distance between some electronic components of the first type of electronic components 300 and the explosion venting part 102 may not be less than a set distance.

[0112] Figures 1-19 The first type of chassis structure is shown. The following section combines... Figures 1-19 The first type of chassis structure will be described in detail.

[0113] Please refer to Figure 2 and Figure 3On the explosion venting side 108, at least a portion of the protective element 200 and the housing 100 have a gap 500, which is configured to communicate with the explosion venting opening 1021.

[0114] For example, such as Figure 3 As shown, a portion of the protective component 200 and the outer casing 100 have a gap 500 between the explosion-proof side 108; as Figure 7 As shown, the protective component 200 and the outer casing 100 have a gap 500 between the explosion-proof side 108; as Figure 9 As shown, a portion of the protective component 200 and the outer casing 100 have a gap 500 between the explosion-proof side 108; as Figure 11 As shown, a portion of the protective component 200 and the outer casing 100 have a gap 500 between the explosion-proof side 108; as Figure 12 As shown, a portion of the protective component 200 and the outer casing 100 have a gap 500 between the explosion-proof side 108; as Figure 17 As shown, the protective component 200 and the outer casing 100 have a gap 500 between the explosion-proof side 108; as Figure 18 As shown, a portion of the protective component 200 and the outer casing 100 have a gap 500 between the explosion-proof side 108.

[0115] Please refer to Figure 1 The anti-touch channel 01 also includes a gap 500. As mentioned above, the anti-touch channel 01 includes an explosion vent 1021, so the anti-touch channel 01 includes an explosion vent 1021 and a gap 500. In this way, by adjusting the position of the protective member 200, the position of the gap 500 can be adjusted, thereby adjusting the position of the anti-touch channel 01, so as to ensure that the first type of electronic component 300 is located outside the anti-touch channel 01; at the same time, by adjusting the position and size of the protective member 200, the size of the gap 500 can be adjusted, thereby adjusting the size of the anti-touch channel 01, so as to facilitate the anti-touch channel 01 to block the passage of the setting component 600 outside the housing 100, and also improve the adaptability to different setting components 600.

[0116] In the above structure, in the case of explosion venting of the chassis, the gap 500 and the explosion venting opening 1021 can provide an explosion venting channel.

[0117] In the above embodiments, the protective member 200 is disposed inside or outside the outer shell 100, and there can be a gap 500 between it and the outer shell 100.

[0118] Figures 1-15An embodiment is shown in which a protective member 200 is disposed within a housing 100, and on the explosion-venting side 108, at least a portion of the protective member 200 has a gap 500 between it and the housing 100. It is understood that on the explosion-venting side 108, at least a portion of the protective member 200 has a gap 500 between it and the inner wall 106 of the housing 100. Thus, the anti-touch channel 01 can prevent a setting component 600 outside the housing 100 from moving out of the anti-touch channel 01.

[0119] like Figure 3 As shown, the inner wall 106 of the outer shell 100 includes the inner wall 106 of the shell 103 and the inner wall 106 of the cover 104. The inner wall 106 of the outer shell 100 includes an inner side wall 1061, an inner bottom wall 1062, and an inner top wall 1063. The inner bottom wall 1062 and the inner top wall 1063 are distributed along a first direction, and the inner side wall 1061 connects the inner bottom wall 1062 and the inner top wall 1063. Specifically, the inner side wall 1061 of the outer shell 100 includes the inner side wall 1061 of the shell 103 and the inner side wall 1061 of the cover 104. The inner bottom wall 1062 of the outer shell 100 is the inner bottom wall 1062 of the shell 103, and the inner top wall 1063 of the outer shell 100 is the inner top wall 1063 of the cover 104.

[0120] Since the protective component 200 is located inside the housing 100, the internal space of the housing 100 can be fully utilized, reducing the impact on the size of the housing 100; it can also prevent the protective component 200 from affecting the appearance of the housing 100.

[0121] For example, such as Figure 3 As shown, on the explosion-proof side 108, there is a gap 500 between a portion of the protective component 200 and the inner wall 106 of the outer casing 100; as Figure 6 As shown, on the explosion venting side 108, there is a gap 500 between the protective component 200 and the inner wall 106 of the outer casing 100.

[0122] Please refer to Figure 1 The explosion vent 102 is located at all positions of the joint 102a between the housing 103 and the cover 104. The explosion vent opening 1021 is the housing opening 1031 of the housing 103, such that the axial direction of the explosion vent opening 1021 is the first direction mentioned above. The axial direction of the explosion vent opening 1021 can be understood as: the direction through the explosion vent opening 1021.

[0123] Combination Figure 1 and Figure 3At least a portion of the protective member 200 is disposed between the explosion vent 1021 and the first type of electronic component 300 in the axial direction of the explosion vent 1021. In this way, the protective member 200 can separate the explosion vent 1021 and the first type of electronic component 300. The protective member 200 facilitates ensuring that the first type of electronic component 300 is located outside the gap 500 (anti-touch channel 01), and also facilitates shielding the first type of electronic component 300 in the axial direction of the explosion vent 1021, effectively improving the anti-touch performance of the protective member 200.

[0124] For example, such as Figure 3 As shown, in the axial direction (first direction) of the explosion vent 1021, a portion of the protective member 200 is disposed between the explosion vent 1021 and the first type of electronic component 300. Alternatively, the protective member 200 may be disposed between the explosion vent 1021 and the first type of electronic component 300 in the axial direction (first direction) of the explosion vent 1021.

[0125] In practice, the explosion venting part 102 includes an explosion venting structure 102b, which is disposed on the cover 104. It can also realize that the axial direction of the explosion venting opening 1021 is the first direction, and can also realize the above embodiment (at least a portion of the protective member 200 is disposed between the explosion venting opening 1021 and the first type of electronic component 300 in the axial direction of the explosion venting opening 1021).

[0126] Please refer to Figure 5a The explosion vent 102 is located at a portion of the junction 102a between the housing 103 and the cover 104, such that the axial direction of the explosion vent 1021 can be a second direction, which is perpendicular to the first direction. Based on this, in the second direction, at least a portion of the protective member 200 is disposed between the explosion vent 1021 and the first type of electronic component 300.

[0127] For example, such as Figure 6 As shown, in the second direction, the protective member 200 is disposed between the explosion vent 1021 and the first type of electronic component 300. Alternatively, in the second direction, a portion of the protective member 200 may be disposed between the explosion vent 1021 and the first type of electronic component 300.

[0128] Please refer to Figure 5b The explosion vent 102 is located at a portion of the joint 102a between the housing 103 and the cover 104, such that the axial direction of the explosion vent 1021 can also be a third direction, which is perpendicular to the first direction. Based on this, in the third direction, at least a portion of the protective member 200 is disposed between the explosion vent 1021 and the first type of electronic component 300.

[0129] In practice, there can be multiple explosion vents 1021. At least one explosion vent 1021 has its axial direction in a second direction, in which a protective member 200 is disposed between one explosion vent 1021 and a portion of the first type of electronic components 300. At least one explosion vent 1021 has its axial direction in a third direction, in which another protective member 200 is disposed between another explosion vent 1021 and another portion of the first type of electronic components 300.

[0130] Please refer to Figure 11 The explosion venting part 102 may include an explosion venting structure 102b, which is disposed in the housing 103. The axial direction of the explosion venting opening 1021 may be a second direction. In the second direction, at least a portion of the protective member 200 is disposed between the explosion venting opening 1021 and the first type of electronic component 300.

[0131] For example, such as Figure 11 As shown, in the axial direction (second direction) of the explosion vent 1021, a portion of the protective member 200 is disposed between the explosion vent 1021 and the first type of electronic component 300. Alternatively, the protective member 200 may be disposed between the explosion vent 1021 and the first type of electronic component 300 in the axial direction (second direction) of the explosion vent 1021.

[0132] The aforementioned gap 500 has a width direction, and the width direction of the gap 500 is the distribution direction of the housing 100, the gap 500, and the protective component 200. For example... Figure 3 As shown, the width direction of the gap 500 is the second direction, and the axial direction of the explosion vent 1021 is the first direction. Therefore, the width direction of the gap 500 is perpendicular to the axial direction of the explosion vent 1021. In this case, in order to prevent the setting component 600 outside the housing 100 from passing through the anti-touch channel 01, the minimum width of the gap 500 is not greater than the setting width.

[0133] In the above embodiments, the minimum width of the gap 500 is not greater than a set width, which can be the minimum width of the setting component 600 outside the housing 100. In this way, the minimum width of the gap 500 is less than or equal to the minimum width of the setting component 600, so that after the setting component 600 enters the gap 500 from the explosion relief opening 1021, it cannot pass through the minimum width of the gap 500. This ensures that the entire setting component 600 cannot pass through the anti-touch channel 01, thereby reducing the probability that the setting component 600 outside the housing 100 will accidentally touch the first type of electronic component 300 inside the housing 100.

[0134] It should be noted that the width direction of the setting component 600 is the same as the width direction of the gap 500. As mentioned earlier, the setting component 600 is a hand, finger, finger-shaped conductive component, or hand-shaped conductive component. Therefore, the smallest part of the setting component 600 first enters the explosion venting opening 1021 and the gap 500, and the larger part of the setting component 600 enters the explosion venting opening 1021 and the gap 500 later. In this way, the smallest part of the gap 500 can prevent the smallest part of the setting component 600 from extending out of the gap 500.

[0135] The specific location of the minimum width of the gap 500 within the gap 500 is selected according to the actual situation, and this application embodiment does not limit this.

[0136] In the above embodiments, by adjusting the position of the protective component 200, the minimum width of the gap 500 can be adjusted, thereby adapting to setting components 600 of different widths and improving the adaptability and flexible adjustment of the chassis.

[0137] In this embodiment, the specific value of the set width is set according to the width of the set component 600. In some embodiments, the set width ranges from 12mm to 50mm.

[0138] For example, the width can be set to 50mm, so that the minimum width of the anti-touch channel 01 is no more than 50mm. In this case, the setting component 600 can be a hand or a hand-shaped conductive component.

[0139] For example, the width can be set to 40mm, so that the minimum width of the anti-touch channel 01 is no more than 40mm. In this case, the setting component 600 can be a hand, a finger, a finger-shaped conductive element, or a hand-shaped conductive element.

[0140] For example, the width can be set to 30mm, so that the minimum width of the anti-touch channel 01 is no more than 30mm. In this case, the setting component 600 can be a finger or a finger-shaped conductive element.

[0141] For example, the width can be set to 20mm, so that the minimum width of the anti-touch channel 01 is no more than 20mm. In this case, the setting component 600 can be a finger or a finger-shaped conductive element.

[0142] For example, the width can be set to 15mm, so that the minimum width of the anti-touch channel 01 is no more than 15mm. In this case, the setting component 600 can be a finger or a finger-shaped conductive element.

[0143] For example, the width can be set to 13mm, so that the minimum width of the anti-touch channel 01 is no more than 13mm. In this case, the setting component 600 can be a finger or a finger-shaped conductive element.

[0144] For example, the width can be set to 12mm, so that the minimum width of the anti-touch channel 01 is no more than 12mm. In this case, the setting component 600 can be a finger or a finger-shaped conductive element.

[0145] In practice, the range of values ​​for the set width can also be adjusted according to the width of the set component 600, for example, the set width can be 51mm or 10mm, etc. This application embodiment does not limit this.

[0146] The above embodiment (the width direction of the gap 500 is perpendicular to the axial direction of the explosion venting opening 1021, and the minimum width of the gap 500 is not greater than the set width) can be applied to the case where the explosion venting part 102 is located at the joint 102, and can also be applied to the case where the explosion venting part 102 includes the explosion venting structure 102b and the explosion venting structure 102b is disposed on the cover 104.

[0147] like Figure 5a and Figure 6 As shown, the axial direction of the explosion vent 1021 is the second direction, and the width direction of the gap 500 can also be the second direction; as Figure 5b As shown, the axial direction of the explosion vent 1021 is a third direction, and the width direction of the gap is also a third direction. Based on this, the width direction of the gap 500 can be parallel to the axial direction of the explosion vent 1021.

[0148] Continue to refer to Figure 5a and Figure 6 To prevent the setting component 600 outside the housing 100 from passing through the anti-touch channel 01, the protective member 200 covers the explosion vent 1021 along the axial projection of the explosion vent 1021. Thus, when the setting component 600 passes through the explosion vent 1021 along its axial direction and enters the gap 500, it will abut against the protective member 200 as it moves along the axial direction of the explosion vent 1021. The protective member 200 prevents the setting component 600 from moving further and thus prevents it from moving out of the gap 500, thereby preventing the setting component 600 from passing through the anti-touch channel 01.

[0149] In the above structure, by adjusting the projection of the protective component 200 along the axial direction of the explosion vent 1021, it can be adapted to explosion vents 1021 of different sizes, thus improving the adaptability and flexibility of the chassis.

[0150] like Figure 5a and Figure 6 As shown, the above embodiment (the width direction of the gap 500 is parallel to the axial direction of the explosion vent 1021, and the projection of the protective member 200 along the axial direction of the explosion vent 1021 covers the explosion vent 1021) can be applied to the case where the explosion vent 102 is located at the joint 102; as Figure 11As shown, the above embodiment (the width direction of the gap 500 is parallel to the axial direction of the explosion vent 1021, and the projection of the protective member 200 along the axial direction of the explosion vent 1021 covers the explosion vent 1021) can also be applied to the case where the explosion vent 102 includes the explosion vent structure 102b and the explosion vent structure 102b is disposed in the housing 103.

[0151] As mentioned above, at least a portion of the protective element 200 is disposed between the explosion vent 1021 and the first type of electronic component 300 in the axial direction of the explosion vent 1021. Based on this, as Figure 1 and Figure 3 As shown, the protective component 200 may include a first protective body 201, and the first protective body 201 and the outer shell 100 form at least a portion of a gap 500 on the explosion relief side 108.

[0152] For example, when the protective member 200 includes only the first protective body 201, the first protective body 201 and the outer shell 100 form a gap 500 on the explosion-venting side 108. When a portion of the protective member 200 is the first protective body 201, the first protective body 201 and the outer shell 100 form a portion of the gap 500 on the explosion-venting side 108.

[0153] like Figure 3 As shown, the axial direction of the explosion vent 1021 is a first direction. In this first direction, the first protective body 201 is located between the explosion vent 1021 and the first type of electronic component 300. Thus, in this first direction, the first protective body 201 can shield the first type of electronic component 300 on the side near the explosion vent 102. If the housing 100 also accommodates a second type of electronic component 400, in the first direction, the first protective body 201 can shield the second type of electronic component 400 on the side near the explosion vent 102.

[0154] Continue to refer to Figure 3 The first protective body 201 and the outer shell 100 form a gap 500 on the explosion-venting side 108, and the width direction of the gap 500 is the second direction. Since the second direction is perpendicular to the first direction, the minimum width of the gap 500 is not greater than the set width.

[0155] like Figure 7 and Figure 11 As shown, the axial direction of the explosion vent 1021 is the second direction, and in the second direction, the first protective body 201 is located between the explosion vent 1021 and the first type of electronic component 300.

[0156] Continue to refer to Figure 7 and Figure 11The first protective body 201 and the outer shell 100 form a gap 500 on the explosion venting side 108. The width direction of the gap 500 is the second direction, and the projection of the first protective body 201 along the second direction covers the explosion venting opening 1021.

[0157] In this embodiment, the first protective body 201 can be a flat plate structure. The first protective body 201 can be perpendicular to the set direction, or the first protective body 201 can be inclined relative to the set direction. Of course, the first protective body 201 can also be a bent plate. In this embodiment, the shape of the first protective body 201 is not limited.

[0158] In this embodiment, the location of the first protective body 201 can be selected based on the location of the explosion vent 102. For example... Figure 1 As shown, with the explosion vent 102 located at all positions of the joint 102a between the housing 103 and the cover 104, the first protective body 201 can be provided on the housing 103. Figure 6 As shown, when the explosion vent 102 is located at a portion of the joint 102a between the housing 103 and the cover 104, the first protective body 201 can also be provided on the cover 104. Figure 11 As shown, when the explosion relief part 102 includes the explosion relief structure 102b, the first protective body 201 can be provided on the cover 104 or the shell 103.

[0159] As mentioned above, when the protective component 200 is part of the first protective body 201, the portion of the gap 500 formed between the first protective body 201 and the outer shell 100 on the explosion-proof side 108 can be understood as: the first portion 501 of the gap 500 formed between the first protective body 201 and the outer shell 100 on the explosion-proof side 108. Based on this, please refer to... Figure 3 The protective component 200 also includes a second protective body 202, which is connected to the first protective body 201.

[0160] In the protective component 200, the first protective body 201 has a top side 2011 and a bottom side 2012 in a first direction. Along the first direction, the bottom side 2012 of the first protective body 201 is closer to the first type of electronic component 300 than the top side 2011 of the first protective body 201. At least a portion of the second protective body 202 is located on the bottom side 2012 of the first protective body 201. For example, a portion of the second protective body 202 is located on the bottom side 2012 of the first protective body 201, and a portion of the second protective body 202 is located on the top side 2011 of the first protective body 201; or, the entire second protective body 202 is located on the bottom side 2012 of the first protective body 201.

[0161] The second protective body 202 and the outer shell 100 form a second portion 502 of a gap 500 on the explosion-proof side 108; wherein the width of the second portion 502 of the gap 500 is not greater than the width of the first portion 501 of the gap 500. In this way, the width of the second portion 502 of the gap 500 is less than or equal to the width of the first portion 501 of the gap 500, which helps to ensure that the minimum width of the gap 500 is not greater than the set width.

[0162] For example, such as Figure 3 As shown, the width of the second part 502 of the gap 500 is equal to the width of the first part 501 of the gap 500. The width direction can be the second direction. The minimum width part of the gap 500 is located in the first part 501 of the gap 500 and also in the second part 502 of the gap 500.

[0163] For example, such as Figure 7 and Figure 11 As shown, the width of the second part 502 of the gap 500 is smaller than the width of the first part 501 of the gap 500, and the width direction can be the second direction. The minimum width part of the gap 500 is located in the second part 502 of the gap 500.

[0164] In the aforementioned protective component 200, the second protective body 202 extends the gap 500, thereby extending the anti-touch channel 01. This prevents the longer setting component 600 from accidentally touching the first type of electronic component 300, further reducing the probability of the setting component 600 accidentally touching the first type of electronic component 300. Moreover, when the width of the second part 502 of the gap 500 is less than the width of the first part 501 of the gap 500, the minimum width of the gap 500 can be adjusted by adjusting the second protective body 202 without adjusting the first protective body 201, which facilitates the design and installation of the protective component 200.

[0165] Please refer to Figure 3 When the explosion vent 102 is located at all positions of the junction 102a between the housing 103 and the cover 104, the second protective body 202 can be arranged around the periphery of the first protective body 201, in which case the second protective body 202 is annular. Of course, the second protective body 202 can also be arranged at a portion of the periphery of the first protective body 201, and the second protective body 202 can be a flat plate structure.

[0166] Please refer to Figure 5a , Figure 6 and Figure 7 When the explosion relief part 102 is located at part of the joint 102a between the shell 103 and the cover 104, the second protective body 202 is a flat plate structure and is arranged along one edge of the first protective body 201.

[0167] Please refer to Figure 11 When the explosion relief part 102 includes the explosion relief structure 102b, the second protective body 202 is a flat plate structure and is disposed along one edge of the first protective body 201.

[0168] like Figure 3 As shown, the structure of the above-mentioned protective component 200, including the first protective body 201 and the second protective body 202, can be applied to situations where the width direction of the gap 500 is perpendicular to the axial direction of the explosion relief opening 1021; as Figure 7 and Figure 11 As shown, the structure of the above-mentioned protective component 200, which includes a first protective body 201 and a second protective body 202, can also be applied to the case where the width direction of the gap 500 is parallel to the axial direction of the explosion relief opening 1021.

[0169] To simplify the installation of the protective component 200, one end of the second protective body 202 can be suspended in the air. For example... Figure 3 As shown, in the first direction, the end of the second protective body 202 furthest from the first protective body 201 can be suspended in mid-air; as Figure 7 and Figure 11 As shown, in the second direction, the end of the second protective body 202 that is away from the first protective body 201 can be suspended in the air.

[0170] Of course, one end of the second protective body 202 can also be installed without being suspended in the air. For example... Figure 4 As shown, in the first direction, the end of the second protective body 202 away from the first protective body 201 is connected to the inner sidewall 1061 of the outer shell 100 (shell 103); or, the end of the second protective body 202 away from the first protective body 201 is connected to the inner bottom wall 1062 of the outer shell 100 (shell 103).

[0171] For example, the inner wall 1061 of the outer casing 100 (shell 103) is provided with a support protrusion 105, and in the first direction, the end of the second protective body 202 away from the first protective body 201 is connected to the support protrusion 105. In practice, the second protective body 202 may also be connected to the inner wall 1061 by other structures, and this embodiment of the application does not limit this.

[0172] When the second protective body 202 is annular, in order to ensure explosion relief, a portion of the second protective body 202 along its circumference is connected to the shell 103; or at least one of the second protective body 202 and the first protective body 201 is provided with a vent.

[0173] The second protective body 202 can also be distributed in a portion of the circumferential direction of the first protective body 201. For example, the first protective body 201 is quadrilateral and the second protective body 202 is distributed on both sides of the first protective body 201.

[0174] Please refer to Figure 8 When the explosion venting part 102 is located at a portion of the joint 102a between the housing 103 and the cover 104, the first protective body 201 is connected to the cover 104, and the second protective body 202 can also be connected to the housing 103. In this case, the first protective body 201 can extend and retract along the first direction to ensure that the protective member 200 moves with the cover 104 during the explosion venting process.

[0175] In order to enable the first protective body 201 to be retractable, the first protective body 201 may include at least two protective parts, and two adjacent protective parts slide together along the first direction.

[0176] Please refer to Figure 9 When the explosion vent 102 is located at a portion of the junction 102a between the housing 103 and the cover 104, the protective member 200 may include a first protective body 201 but not a second protective body 202. A portion of the first protective body 201 is fitted against the inner wall 1061 of the housing 103, and a gap 500 is formed between another portion of the first protective body 201 and the inner wall 1061 of the cover 104. In this case, the first protective body 201 can extend and retract along a first direction to ensure that the first protective body 201 moves with the cover 104 during the explosion venting process.

[0177] It should be noted that, Figure 9 In the structure shown, there is a gap 500 between the portion of the protective element 200 and the outer casing 100 on the explosion venting side 108.

[0178] Please refer to Figure 5a When the width direction of the gap 500 is parallel to the axial direction of the explosion relief opening 1021, the protective component 200 may further include a third protective body 203. The third protective body 203 is connected to the first protective body 201. At least a portion of the third protective body 203 is located on the top side 2011 of the first protective body 201. The third protective body 203 is disposed on the cover 104. In this way, the first protective body 201 can be disposed on the cover 104 through the third protective body 203, which facilitates the installation of the protective component 200.

[0179] like Figure 11As shown, the third protective body 203 can also be disposed within the housing 103 of the outer casing 100, and shield the first type of electronic component 300 in the first direction. Thus, when the setting component 600 is long and passes through the gap 500, the third protective body 203 can prevent the setting component 600 from contacting the first type of electronic component 300, further reducing the probability of the setting component 600 accidentally touching the first type of electronic component 300, and further reducing safety hazards; simultaneously, the first protective body 201 can be disposed within the housing 103 through the third protective body 203, facilitating the installation of the protective component 200.

[0180] In practice, the second protective body 202 and the third protective body 203 can be provided simultaneously. This can be understood as the protective component 200 comprising the first protective body 201, the second protective body 202, and the third protective body 203. In this case, the protective component 200 can be a cover structure, with the first protective body 201 and the second protective body 202 both arranged around the periphery of the third protective body 203; or, the protective component 200 can have other structures, for example, with the first protective body 201 and the second protective body 202 both distributed on one side of the third protective body 203.

[0181] In practice, the second protective body 202 and the third protective body 203 can also exist independently. It can be understood that the protective component 200 includes the first protective body 201 and the second protective body 202, or the protective component 200 includes the first protective body 201 and the third protective body 203.

[0182] In this embodiment of the application, when the protective member 200 is located inside the outer shell 100, in addition to the structure of the protective member 200 mentioned above (the protective member 200 includes the first protective body 201), the protective member 200 can also be a cover structure.

[0183] Please refer to Figure 12 The protective component 200 is a protective cover 200a, which covers the outside of the first type of electronic component 300, and the protective component 200 is disposed in the housing 103.

[0184] like Figure 12 As shown, the housing opening 1031 of the housing 103 forms an explosion venting opening (not marked in the figure). The axial direction of the explosion venting opening is the first direction, the width direction of the two gaps 500 is the second direction, and the width direction of the two gaps 500 is the third direction. The protective cover 200a can be used when the width direction of the gaps 500 is perpendicular to the axial direction of the explosion venting opening 1021.

[0185] Of course, the protective cover 200a can also be used when the width direction of the gap 500 is parallel to the axial direction of the explosion relief opening 1021.

[0186] Since the protective cover 200a is placed outside the first type of electronic component 300, the protective cover 200a plays a protective role. When the width direction of the gap 500 is perpendicular to the axial direction of the explosion vent 1021, it is not necessary to ensure that the minimum width of the gap 500 is not greater than the set width. Correspondingly, when the width direction of the gap 500 is parallel to the axial direction of the explosion vent 1021, it is also not necessary to ensure that the projection of the protective component 200 along the axial direction of the explosion vent 1021 covers the explosion vent 1021.

[0187] When the protective component 200 is a protective cover 200a, the protective cover 200a can be connected to or in contact with the surface where the first type of electronic component 300 is located. For example, the first type of electronic component 300 is disposed on the circuit board 700, and the protective cover 200a can be connected to or in contact with the circuit board 700. In this way, the first type of electronic component 300 is disposed within the housing 100 through the circuit board 700.

[0188] like Figure 3 As shown, the protective component 200 includes a first protective body 201 and a second protective body 202. In this case, the second protective body 202 is annular, and the first protective body 201 and the second protective body 202 can form a protective cover 200a.

[0189] like Figure 11 As shown, the protective component 200 includes a first protective body 201, a second protective body 202, and a third protective body 203. In this case, the first protective body 201 and the second protective body 202 are both annular, and the first protective body 201, the second protective body 202, and the third protective body 203 can form a protective cover 200a.

[0190] In practice, the protective component 200 includes a first protective body 201 and a third protective body 203. In this case, the first protective body 201 is annular, and the first protective body 201 and the third protective body 203 can form a protective cover 200a.

[0191] In this embodiment, when the protective member 200 is located inside the housing 100, the protective member 200 can be a conductive member, and the protective member 200 and the housing 100 are electrically connected to form a closed circuit. The conductive member can be a metal member, graphite, or other conductive material.

[0192] For example, the protective member 200 is electrically connected to the housing 100 on both sides in the second direction, forming a closed circuit. For example, the protective member 200 is electrically connected to the housing 100 on both sides in the first direction, forming a closed circuit.

[0193] In the above embodiments, the protective component 200 can be grounded through the outer shell 100, so that the protective component 200 forms an electromagnetic shield. During the normal operation of the power equipment, the protective component 200 can reduce or even shield the electromagnetic interference of the power equipment, and at the same time, it can meet the EMC (electromagnetic compatibility) requirements of the power equipment.

[0194] As mentioned above, the protective component 200 can include a first protective body 201, or a first protective body 201 and a second protective body 202, or a first protective body 201, a second protective body 202 and a third protective body 203, or a protective cover 200a. All of these configurations achieve the following: the protective component 200 can be a conductive component, and the protective component 200 and the outer casing 100 are electrically connected to form a closed circuit. When the protective component 200 is a protective cover 200a, the protective component 200 forms an electromagnetic shielding cover, providing a better electromagnetic shielding effect.

[0195] For example, such as Figure 4 and Figure 8 As shown, the protective component 200 includes a first protective body 201 and a second protective body 202, both of which are conductive. The first protective body 201 and the second protective body 202 are electrically connected. The end of the first protective body 201 away from the second protective body 202 along a first direction is electrically connected to the cover 104, and the end of the second protective body 202 away from the first protective body 201 along a first or second direction is electrically connected to the housing 103. The cover 104 and the housing 103 are electrically connected. In this way, the first protective body 201, the second protective body 202, the housing 103, and the cover 104 can form a closed circuit, and the protective component 200 can be grounded, thus forming an electromagnetic shield.

[0196] For example, such as Figure 11 As shown, the protective component 200 includes a first protective body 201, a second protective body 202, and a third protective body 203. All three protective bodies 201, 202, and 203 are conductive. The second and third protective bodies 202 are electrically connected to the first protective body 201. The first protective body 201 is located on both sides of the third protective body 203 in the second direction, and the second protective body 202 is also located on both sides of the third protective body 203 in the second direction. The second protective bodies 202 on both sides of the third protective body 203 are electrically connected to the housing 103. Thus, the first protective body 201, the second protective body 202, the third protective body 203, and the housing 103 can form a closed circuit, and the protective component 200 can be grounded, thereby forming an electromagnetic shield.

[0197] In this embodiment of the application, when the protective component 200 does not need to have an electromagnetic shielding function, the protective component 200 can also be an insulating component. For example, the protective component 200 can be a plastic component or the like.

[0198] The specific structure of the protective component 200 mentioned above can be applied to situations where the protective component 200 is an insulating component.

[0199] Please refer to Figure 13 The protective component 200 may be provided with a protrusion 208, which protrudes from the side of the protective component 200 away from the first type of electronic component 300. In this way, the protrusion 208 can make way for the first type of electronic component 300, so as to facilitate the installation of the protective component 200; at the same time, the protrusion 208 can enhance the overall strength of the protective component 200 and reduce the probability of the protective component 200 being damaged by the explosion of electrical equipment.

[0200] Continue to refer to Figure 13 The protective component 200 may also be provided with a recess 206, which is recessed towards the side of the protective component 200 closest to the first type of electronic component 300. In this way, the recess 206 can enhance the overall strength of the first protective body 201 and reduce the probability of the protective component 200 being damaged by an explosion of electrical equipment.

[0201] In practice, the protective component 200 can be provided with a protrusion 208 or a recess 206 alone, or it can be provided with both protrusion 208 and recess 206. The specific shape and number of the protrusion 208 and recess 206 are selected according to the actual situation, and this application embodiment does not limit this.

[0202] When the protective member 200 includes a first protective body 201, at least one of the protrusion 208 and the recess 206 may be provided on the first protective body 201; when the protective member 200 includes a first protective body 201 and a second protective body 202, at least one of the first protective body 201 and the second protective body 202 is provided with at least one of the protrusion 208 and the recess 206; when the protective member 200 includes a first protective body 201, a second protective body 202 and a third protective body 203, at least one of the first protective body 201, the second protective body 202 and the third protective body 203 is provided with at least one of the protrusion 208 and the recess 206.

[0203] The preceding text described an embodiment where the protective member 200 is located within the housing and a gap 500 exists between at least a portion of the protective member 200 on the explosion-proof side 108 and the housing 100. The following describes an embodiment where the protective member 200 is located outside the housing 100 and a gap 500 exists between a portion of the protective member 200 on the explosion-proof side 108 and the housing 100. It is understood that a gap 500 exists between a portion of the protective member 200 on the explosion-proof side 108 and the outer wall 107 of the housing 100.

[0204] Please refer to Figure 16 and Figure 17 The protective member 200 is disposed outside the housing 100, and a portion of the protective member 200 is positioned axially away from the housing 100 along the explosion vent opening 1021. In this case, the gap 500 connects the external environment of the housing 100 and the explosion vent opening 1021. The width direction of the gap 500 is parallel to the axial direction of the explosion vent opening 1021, and the projection of the protective member 200 along the axial direction of the explosion vent opening 1021 covers the explosion vent opening 1021. Thus, the anti-touch channel 01 can prevent the setting component 600 outside the housing 100 from entering the anti-touch channel 01.

[0205] For example, the protective element 200 includes a fourth protective body 204 and a fifth protective body 205. The fourth protective body 204 is configured at a position in the explosion vent 1021 away from the housing 100 along its axial direction. The fifth protective body 205 connects the fourth protective body 204 and the housing 100. On the explosion vent side 108, there is a gap 500 between the fourth protective body 204 and the housing 100. The projection of the fourth protective body 204 in the axial direction of the explosion vent 1021 covers the explosion vent 1021.

[0206] In the above structure, the protective component 200 is located outside the housing 100, which saves internal space of the housing 100 and facilitates the installation of the protective component 200.

[0207] As mentioned above, the width direction of the gap 500 is the distribution direction of the protective member 200, the gap 500, and the housing 100. The gap 500 also has a length direction, which is perpendicular to the width direction of the gap 500. For example, as... Figure 17 As shown, the gap 500 is annular, and the length direction of the gap 500 is the first direction; for example, when the gap 500 is strip-shaped, the length direction of the gap 500 includes a direction perpendicular to the width direction of the gap 500. The length direction of the gap 500 includes multiple directions, as long as it is perpendicular to the width direction of the gap 500.

[0208] Since the protective component 200 is located outside the housing 100, at least one end of the gap 500 may have a gap opening 503 along the length of the gap 500. This allows the setting component 600 outside the housing 100 to easily enter the anti-touch channel 01 through the gap opening 503 and accidentally touch the first type of electronic component 300. To further reduce the probability of the setting component 600 accidentally touching the first type of electronic component 300, the minimum width of the gap 500 is not greater than the set width.

[0209] The set width can be the minimum width of the setting component 600 outside the housing 100, and the width direction of the setting component 600 is the width direction of the gap 500. In this way, the minimum width of the gap 500 is less than or equal to the minimum width of the setting component 600, so that after the setting component 600 enters the gap 500 from the gap opening 503, it cannot pass through the minimum width part of the gap 500. This ensures that the entire setting component 600 cannot pass through the anti-touch channel 01, thereby reducing the probability that the setting component 600 outside the housing 100 will accidentally touch the first type of electronic component 300 inside the housing 100.

[0210] For specific values ​​to set the width, please refer to the previous text; they will not be repeated here.

[0211] like Figure 16 and Figure 17 As shown, the above embodiment (where the protective member 200 is located outside the housing 100, and a gap 500 exists between the portion of the protective member 200 and the housing 100 on the explosion-proof side 108) can be applied to the case where the explosion-proof portion 102 is located at the joint 102a of the housing 103 and the cover 104. In the case where the explosion-proof portion 102 is located at the joint 102a of the housing 103 and the cover 104, as... Figure 16 As shown, the protective element 200 is a single, annular component. Of course, the protective element 200 can also be at least two, distributed along the annular explosion vent 102, with a gap between adjacent protective elements 200 or adjacent protective elements 200 mating together.

[0212] like Figure 18 As shown, the above embodiment (the protective member 200 is located outside the housing 100, and there is a gap 500 between the portion of the protective member 200 on the explosion venting side 108 and the housing 100) can also be applied to the case where the explosion venting part 102 includes the explosion venting structure 102b.

[0213] In the above embodiment (the protective element 200 is located outside the housing 100, and there is a gap 500 between the portion of the protective element 200 on the explosion relief side 108 and the housing 100), the protective element 200 can be a conductive element or an insulating element.

[0214] Please refer to Figure 3When the protective component 200 is located within the housing 100, the gap 500 is a portion of the receiving cavity 101 of the housing 100. The gap 500 and other portions of the receiving cavity 101, except for the gap 500, can be directly connected. For example... Figure 9 As shown, when the gap 500 and the other parts of the receiving cavity 101 are not directly connected, the protective member 200 can be provided with a vent 207, and the gap 500 and the vent 207 are connected. In this way, the gap 500 can be indirectly connected to the other parts of the receiving cavity 101, except for the gap 500, through the vent 207.

[0215] It should be noted that in the event of an explosion venting in the chassis, the vent 207, the gap 500, and the explosion vent opening 1021 provide an explosion venting channel.

[0216] When the protective component 200 is a protective cover 200a, the first type of electronic component 300 may generate gas under abnormal conditions. In this case, such as Figure 12 As shown, in order to ensure that the gas generated by the first type of electronic component 300 is discharged from the protective cover 200a and released through the explosion vent 1021, the protective component 200 needs to be provided with a vent 207. This can be understood as: the protective cover 200a is provided with a vent 207, and the vent 207 is connected to the gap 500. In this case, the gap 500 is connected to the interior of the protective cover 200a through the vent 207. It should be noted that the internal space of the protective cover 200a is also part of the receiving cavity 101 of the outer shell 100.

[0217] It should be noted that the radial dimension of the vent 207 is smaller than the set width, and the radial direction of the vent 207 is perpendicular to the axis of the through hole. The vent 207 can be a circular hole, a square hole, or a hole of other shapes.

[0218] In practice, while the gap 500 can be directly connected to the other parts of the receiving cavity 101 except for the gap 500, the gap 500 can also be indirectly connected to the other parts of the receiving cavity 101 except for the gap 500 through the vent 207.

[0219] Please refer to Figure 17 and Figure 18 As shown, when the protective component 200 is located inside the housing 100, the gap 500 is located outside the receiving cavity 101 of the housing 100, and the gap 500 connects the external environment and the explosion relief opening 1021. In this case, the protective component 200 may or may not have a vent 207.

[0220] In the embodiments of this application, such as Figure 1 As shown, the protective element 200 is configured to correspond one-to-one with the explosion vent 1021. For example... Figure 15As shown, the protective component 200 is configured to correspond to one explosion vent 1021, which can be understood as: multiple protective components 200 correspond to one explosion vent 1021.

[0221] The correspondence between the protective component 200 and the explosion vent 1021 is not limited by the relative positions of the protective component 200 and the outer shell 100, nor by the specific structure of the explosion vent 102.

[0222] In the embodiment described above (where at least a portion of the protective member 200 and the housing 100 have a gap 500 between the explosion relief side 108), the protective member 200 achieves the anti-contact function of the anti-contact channel 01 by constraining the gap 500 or blocking the setting member 600. Therefore, in order to improve the protective performance of the protective member 200, the protective member 200 is a rigid structure, such as a protective plate or a protective net.

[0223] In this application, in addition to the embodiments described above (where at least a portion of the protective member 200 and the outer casing 100 have a gap 500 between the explosion-venting side 108), there are other embodiments. Please refer to... Figure 19 The protective component 200 is configured to fit flush with the housing 100 and cover the explosion vent opening. Figure 19 (Not shown in the image), protective component 200 is a breathable component.

[0224] It should be noted that, Figure 19 The location of the explosion vent opening can be referenced to the location of the explosion vent 102, which is located at a portion of the joint 102a between the housing 103 and the cover 104. In the event of an explosion venting in the chassis, the explosion vent opening 1021 and the venting element provide an explosion venting channel.

[0225] Since the protective component 200 is configured to fit snugly against the outer casing 100, the impact of the protective component 200 on the chassis volume can be reduced; moreover, by fitting snugly against the outer casing 100, the protective component 200 covers the explosion vent opening 1021, thereby improving the protective effect of the protective component 200, which can be understood as improving the anti-touch effect of the anti-touch channel 01.

[0226] As described above, the explosion vent 102 is located at least partially at the junction 102a of the cover 104 and the housing 103. In this case, the protective member 200 is located outside the housing 100 to ensure that the protective member 200 fits snugly against the housing 100. Since the cover 104 and the housing 103 will move relative to each other during the explosion venting process, causing them to separate at the junction 102a and form an explosion venting opening 1021, the relative movement of the cover 104 and the housing 103 makes the protective member 200 more susceptible to damage. To reduce the probability of damage to the protective member 200, the protective member 200 is a stretchable flexible protective member 200b. Thus, during the explosion venting process, the protective member 200 can stretch and deform with the relative movement of the cover 104 and the housing 103, ensuring that the protective member 200 fits snugly against the housing 100 and reducing the probability of damage.

[0227] The flexible protective component 200b can be a fiber product or a polymer film product, etc. For example, the protective component 200 can be a protective cloth, a protective mesh, or a polymer film. The protective cloth can be fire-retardant nylon cloth or insulating gauze, etc. The embodiments of this application do not limit the specific type of the flexible protective component 200b.

[0228] As described above, the explosion vent 102 includes an explosion vent structure 102b, and the explosion vent 1021b of the explosion vent structure 102b is configured to form an explosion vent opening 1021. In this case, the protective member 200 can be located outside the housing 100, or the protective member 200 can be located inside the housing 100. For example, when the explosion vent 1021b is located outside the housing 100, the protective member 200 can be located outside the housing 100; when the explosion vent 1021b is located inside the housing 100, the protective member 200 can be located inside the housing 100.

[0229] During the formation of the explosion vent 1021 in the explosion vent 102b of the explosion vent structure 102b, the surface of the explosion vent 1021b may or may not deform. If the surface of the explosion vent 1021b deforms, the protective component 200 is more easily damaged. To reduce the probability of damage to the protective component 200, the protective component 200 is a stretchable flexible protective component 200b. Thus, during the explosion venting process, the protective component 200 can stretch and deform along with the surface deformation of the explosion vent 1021b, ensuring that the protective component 200 fits snugly against the outer shell 100 and reducing the probability of damage.

[0230] The types of flexible protective components 200b can be found in the previous text and will not be repeated here.

[0231] When the protective component 200 is a flexible protective component 200b, in order to facilitate the fit between the flexible protective component 200b and the outer shell 100, the flexible protective component 200b can wrap around the outer shell 100. In this way, the fit strength between the flexible protective component 200b and the outer shell 100 can be strengthened, and the protective effect of the flexible protective component 200b can be improved.

[0232] The circumferential direction of the flexible protective member 200b on the outer casing 100 can be selected according to the position of the explosion vent 102. For example, the flexible protective member 200b surrounds the outer casing 100 in a second direction. This application embodiment does not limit this.

[0233] In this embodiment of the application, when the protective member 200 is configured to be attached to the outer shell 100 and cover the explosion venting opening 1021, and the protective member 200 is a breathable member, the protective member 200 can be a conductive member or an insulating member.

[0234] For example, to improve safety performance, the protective component 200 is an insulating component.

[0235] For example, in order to achieve electromagnetic shielding, the protective component 200 can be a conductive component. The protective component 200 can be electrically connected to the housing 100 and form a closed circuit by fitting it into the housing 100.

[0236] Figures 20-24 The second type of chassis structure is shown below. (Followed by...) Figures 20-24 The second type of chassis structure will be described in detail.

[0237] As mentioned earlier, in the chassis, the first type of electronic component 300 is configured such that the minimum distance between it and the explosion vent 1021 is not less than a set distance. The setting component 600 can be a hand, finger, finger-shaped conductive component, or hand-shaped conductive component. Based on the type of setting component 600, the set distance can be the length of the setting component 600. Specifically, the set distance can be 180mm. In this way, the first type of electronic component 300 is configured such that the minimum distance between it and the explosion vent 1021 is not less than the length of the setting component 600, thereby reducing the probability of the setting component 600 accidentally contacting the first type of electronic component 300.

[0238] In practice, the specific value of the setting distance can also be adjusted according to the type of setting component 600. For example, the setting distance is 200mm, and it is not limited to 180mm.

[0239] like Figure 21As shown, when the explosion venting part 102 is located at the junction 102a of the housing 103 and the cover 104, in order to ensure that the minimum distance between the first type of electronic component 300 and the explosion venting opening 1021 is not less than a preset distance, the minimum distance L1 between the explosion venting part 102 and the first type of electronic component 300 in the first direction is not less than a first set value.

[0240] It should be noted that, Figure 21 The image shows two first-class electronic components 300, and the minimum distance L1 between the first-class electronic components 300 and the explosion venting part 102 in the first direction is the minimum value among the minimum distances between the two first-class electronic components 300 and the explosion venting part 102 in the first direction. Figure 21 The first type of electronic component 300 consists of two components, which is exemplary and not intended to limit the embodiments of this application.

[0242] In practice, to further ensure that the minimum distance between the first type of electronic component 300 and the explosion vent 1021 is not less than a preset distance, the minimum distance L1 between the explosion vent 102 and the first type of electronic component 300 in the first direction is not less than a first set value, and the minimum distance L2 between the inner wall 1061 on the side where the explosion vent 102 is located and the first type of electronic component 300 in the second direction is not less than a second set value.

[0243] like Figure 23 As shown, the explosion venting section 102 includes an explosion venting structure 102b. To ensure that the minimum distance between the first type of electronic component 300 and the explosion venting opening 1021 is not less than a preset distance, the minimum distance L3 between the first type of electronic component 300 and the explosion venting opening 1021 in the axial direction (second direction) of the explosion venting opening 1021 is not less than a third preset value. The axial direction of the explosion venting opening 1021 is the second direction.

[0244] It should be noted that, Figure 23 The image shows two Class I electronic components 300, and the minimum distance L3 between the Class I electronic components 300 and the explosion vent 1021 in the axial direction of the explosion vent 1021 is the minimum value among the minimum distances between the two Class I electronic components 300 and the explosion vent 1021 in the axial direction of the explosion vent 1021. Figure 23 The first type of electronic component 300 consists of two components, which is exemplary and not intended to limit the embodiments of this application.

[0245] Continue to refer to Figure 23 In order to ensure that the minimum distance between the first type of electronic component 300 and the explosion vent 1021 is not less than a preset distance, the minimum distance L4 between the first type of electronic component 300 and the explosion vent 1021 in the first direction is not less than a fourth preset value.

[0246] like Figure 24 As shown, in order to ensure that the minimum distance between the first type of electronic component 300 and the explosion vent 1021 is not less than a preset distance, the minimum distance L5 between the first type of electronic component 300 and the explosion vent 1021 in the third direction is not less than a fifth set value, and the third direction is perpendicular to the axial direction of the explosion vent 1021.

[0247] In practice, the axial direction of the explosion vent 1021 can also be a third direction or a first direction. For the requirements of the relevant distance, please refer to the previous text (the embodiment where the axial direction of the explosion vent 1021 is a second direction).

[0248] In practice, to further ensure that the minimum distance between the first type of electronic component 300 and the explosion vent 1021 is not less than a preset distance, the minimum distance L3 between the first type of electronic component 300 and the explosion vent 1021 in the axial direction of the explosion vent 1021 is not less than a third preset value, the minimum distance L4 between the first type of electronic component 300 and the explosion vent 1021 in one direction perpendicular to the axial direction is not less than a fourth preset value, and the minimum distance L5 between the first type of electronic component 300 and the explosion vent 1021 in another direction perpendicular to the axial direction is not less than a fifth preset value.
