[0033] Exemplary embodiments will be described in detail below, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0034] In the prior art, the interior of the distribution box is filled with a two-component polyurethane potting adhesive. The two-component polyurethane potting adhesive is filled around the components in the distribution box to protect the components in the distribution box and improve the safety of the distribution box. However, the curing time of the two-component polyurethane potting adhesive is relatively long. When it is necessary to repair or replace the components in the distribution box, a scraper or other tools are required to scrape off the two-component polyurethane potting around the components. The operation of removing the cured two-component polyurethane potting adhesive around the components is relatively inconvenient, increasing the repair difficulty and possibly causing damage to the components.

[0035] Based on this, an embodiment of the present application provides a distribution box, including a housing, a first protective member, and components. A first accommodation cavity is provided in the housing, the components are arranged in the first accommodation cavity, and the first protective member is filled in the first accommodation cavity. The first protective member covers at least part of the components, so that the first protective member can form an anti-impact protective layer around the components. Thus, when the distribution box is subjected to external impact and vibration, the first protective member can reduce the vibration and impact received by the housing and the components, thereby protecting the housing and the components, preventing the components from being damaged or loosened, and improving the safety of the distribution box. The housing has a channel for the first protective member to enter and flow out. When it is necessary to repair or replace the components, the first protective member can be made to flow out of the first accommodation cavity through the channel on the housing, and thus the first protective member around the components can be removed. Therefore, it is convenient to remove the first protective member, making the repair and replacement of the components more convenient and improving the repair or replacement efficiency of the components.

[0036] The embodiments of the present application will be described below with reference to the drawings.

[0037] Refer to Figures 1 to 3, the distribution box 100 provided by the embodiment of the present application includes: a housing 110, a first protective member 120, and components 130. There is a first accommodation cavity 111 inside the housing 110. The components 130 are arranged in the first accommodation cavity 111. The first protective member 120 is filled in the first accommodation cavity 111. The first protective member 120 covers at least part of the components 130. The first protective member 120 is used to protect the components 130. There is a channel on the housing 110 for the first protective member 120 to enter and flow out of the first accommodation cavity 111.

[0038] Wherein, the channel is communicated with the first accommodation cavity 111 so that the first protective member 120 can enter and flow out of the first accommodation cavity 111 through the channel.

[0039] Specifically, when assembling the distribution box, first install each component 130 in the housing 110 in sequence, and then make the first protective member 120 enter the first accommodation cavity 111 through the channel. After the first protective member 120 enters the first accommodation cavity 111, it can flow towards the bottom of the first accommodation cavity 111, and then be filled in the first accommodation cavity 111. The first protective member 120 covers at least part of the components 130 to facilitate the protection of the components 130. When it is necessary to repair or replace the components 130, the components 130 can be disassembled from the first accommodation cavity 111 for repair or replacement after the first protective member 120 flows out of the first accommodation cavity 111 through the channel.

[0040] It should be noted that the number of components 130 can be multiple. The multiple components 130 are arranged in the first accommodation cavity 111. The first protective member 120 covers at least part of the circumferences of the components 130 that are farther away from the bottom of the first accommodation cavity 111 so that the first protective member 120 can protect all the components 130. Among them, the components 130 can include circuit breakers, fuses, current acquisition components, etc.

[0041] It can be understood that the filling height of the first protective member 120 in the accommodation cavity 111 can be adjusted adaptively according to actual needs. The larger the volume of the first protective member 120, the larger the circumferential area of the first protective member 120 covering the components 130, and thus the better the protection effect of the first protective member 120 on the components 130.

[0042] In some examples, the first protective member 120 covers the entire circumference of the components 130.

[0043] The distribution box 100 provided by the embodiment of the present application fills the first protection member 120 in the first accommodation cavity 111, and the first protection member 120 covers at least part of the components 130, so that the first protection member 120 can form an anti-impact protection layer on the periphery of the components 130. Further, when the distribution box 100 is subjected to external impact and vibration, the first protection member 120 can reduce the vibration and impact received by the housing 110 and the components 130, thereby protecting the housing 110 and the components 130, avoiding damage or loosening of the components 130, and improving the safety of the distribution box 100. When it is necessary to repair or replace the components 130, the first protection member 120 can be made to flow out of the first accommodation cavity 111 through the channel on the housing 110, that is, the first protection member 120 on the periphery of the components 130 can be removed. Thus, it is convenient to remove the first protection member 120, making the repair and replacement of the components 130 more convenient and improving the repair and replacement efficiency of the components 130. Compared with using a scraper to remove the two-component polyurethane potting adhesive, which may damage the components 130, the distribution box 100 provided by the embodiment of the present application causes less damage to the components 130 during repair, and the repair cost of the components 130 is lower.

[0044] Referring to Figure 2 and Figure 3 , in a specific implementation, the channel includes at least one openable and closable through hole 112, and the through hole 112 communicates with the first accommodation cavity 111.

[0045] Exemplarily, the through hole 112 can be a round hole, an oval hole or a polygonal hole. The more the number of through holes 112, the larger the area of the channel, and further, the faster the first protection member 120 flows out or into the first accommodation cavity 111.

[0046] Specifically, when it is necessary to repair and replace the components 130, the through hole 112 can be made to face downwards, so that the first protection member 120 can flow towards the through hole 112 under the action of gravity and flow out of the first accommodation cavity 111 through the through hole 112.

[0047] In some embodiments, a cover plate 160 is detachably connected to the housing 110, and the cover plate 160 is used to open and close the through hole 112.

[0048] Among them, by providing the cover plate 160, when it is necessary to make the first protection member 120 flow out of the first accommodation cavity 111, the shielding of the through hole 112 is removed to open the through hole 112. When it is not necessary to make the first protection member 120 flow out of the first accommodation cavity 111, the cover plate 160 can be used to shield the through hole 112 to close the through hole 112, thereby avoiding the first protection member 120 from flowing out through the through hole 112, and at the same time, avoiding impurities or dust outside the housing 110 from entering the first accommodation cavity 111 through the through hole 112.

[0049] Exemplarily, the shape of the cover plate 160 can be circular, oval or polygonal.

[0050] It can be understood that the number of the cover plates 160 can be one or multiple, as long as the cover plates 160 can close all the through holes 112. The connection manner between the cover plate 160 and the housing 110 can be snap connection, threaded connection, pin connection or other detachable connection manners.

[0051] In some examples, one side of the cover plate 160 can be hinged to the housing 110, and the other side of the cover plate 160 is detachably connected to the housing 110.

[0052] At least one protrusion can be provided on the cover plate 160. The protrusion is inserted into the through hole 112 to close the through hole 112. The protrusion is removed from the through hole 112 to open the through hole 112.

[0053] In some other examples, the housing 110 includes a bottom plate, a top plate and four side plates. The four side plates are arranged between the top plate and the bottom plate. The bottom plate, the top plate and the four side plates jointly enclose to form a first accommodation cavity 111. The top plate is detachably connected to each side plate, and the top plate forms the cover plate 160.

[0054] In some embodiments, the component 130 is connected to the bottom wall of the housing 110, and the through hole 112 is located on at least one of the top wall and the side wall of the housing 110.

[0055] Wherein, there is a certain distance between the through hole 112 and the component 130 to prevent the first protective member 120 around the component 130 from flowing out of the first accommodation cavity 111 through the through hole 112 during normal operation, so as to affect the protection effect of the first protective member 120.

[0056] Exemplarily, each through hole 112 is located on the top wall of the housing 110. When the component 130 needs to be repaired and replaced, by placing the top wall of the housing 110 downward, each through hole 112 can face downward, which is convenient for the first protective member 120 to flow out of the first accommodation cavity 111 through the through hole 112. Further, the number of the cover plates 160 is one, and the cover plate 160 can close or open each through hole 112 simultaneously.

[0057] The number of the through holes 112 is at least two, and the through holes 112 are arranged at intervals in sequence.

[0058] In some embodiments, the first protective member 120 includes a first non-Newtonian fluid with shear thickening characteristics.

[0059] Among them, the first non-Newtonian fluid has cold flow characteristics. Specifically, when filling the first protective member 120 into the first accommodating cavity 111, only the preformed first protective member 120 needs to be placed at any position within the first accommodating cavity 111. After a period of time, under the action of its own weight, the first protective member 120 will flow and disperse towards the bottom of the first accommodating cavity 111 until the bottom of the first accommodating cavity 111 is completely filled. At the same time, the first protective member 120 can flow and fill the periphery of the component 130 and the gap between the housing 110 and the component 130, thereby forming an all-round protection for the housing 110 and the component 130. Specifically, the first protective member 120 can be preformed using a mold or other shaping tools first.

[0060] The shear thickening characteristic means that the viscosity of the first non-Newtonian fluid increases with the increase of the shear rate. When not subjected to external impact, the first non-Newtonian fluid is in a soft state. When the distribution box 100 is subjected to a shear force, the viscosity of the first non-Newtonian fluid will increase rapidly, causing the first non-Newtonian fluid to change from a soft state to a solid state, and then the impact force can be absorbed and dispersed through the first protective member 120. The first protective member 120 can form an impact-resistant protective layer around the component 130 in a short time, reducing the impact and vibration received by the housing 110 and the component 130, thereby protecting the distribution box 100 and the component 130.

[0061] Exemplarily, the first non-Newtonian fluid includes a solid organic borosiloxane polymer. When not subjected to external force, the solid organic borosiloxane polymer is a soft polymer viscoelastic solid, so that the first non-Newtonian fluid can enter or flow out of the first accommodating cavity 111 through the channel. Thus, when it is necessary to repair and replace the component 130, the solid organic borosiloxane polymer can flow out through the channel, making it more convenient to repair and replace the component 130. At the same time, compared with the two-component polyurethane potting adhesive in the prior art that may release harmful substances, the solid organic borosiloxane polymer has better safety.

[0062] When subjected to an external shear force, the storage modulus and strength of the solid organic borosiloxane polymer increase several times instantaneously, and then exhibit a hard solid property, thereby forming a protective layer for the component 130 in the distribution box 100.

[0063] It can be understood that the first non-Newtonian fluid has good insulation performance. The first non-Newtonian fluid covers the periphery of the component 130, and thus can effectively isolate the component 130 to prevent electrical failures such as short circuits or electric shocks of the component 130.

[0064] In some embodiments, the first protective member 120 further includes a heat-conducting filler.

[0065] Among them, when the distribution box 100 is working, components such as the component 130 will generate a large amount of heat. If the heat cannot be dissipated in time and effectively, the temperature of the component 130 will rise, which may further cause the component 130 to malfunction.

[0066] The heat-conducting filler refers to the filler added to the first non-Newtonian fluid to increase the thermal conductivity of the first non-Newtonian fluid. By adding the heat-conducting filler to the first protective member 120, the heat generated by the component 130 can be timely and effectively dispersed to the first protective member 120 and the housing 110 through the heat-conducting filler in the first protective member 120, thereby reducing the temperature of the component 130, realizing the heat dissipation of the component 130, and improving the thermal stability of the distribution box 100.

[0067] Exemplarily, the heat-conducting filler can be silica, which has high electrical insulation, and good thermal stability and thermal conductivity.

[0068] It can be understood that the first protective member 120 can also include other fillers to supplement other aspects of the performance of the first protective member 120. For example, non-magnetic fillers and fillers with better compressive properties are used. Other fillers can include calcium carbonate and aluminum oxide, etc.

[0069] In some embodiments, the component 130 has at least one first connection portion, the housing 110 has at least one second connection portion, the first connection portion is connected to the second connection portion, and the first protective member 120 covers the connection portion between the first connection portion and the second connection portion.

[0070] Among them, when the first protective member 120 covers the entire circumferential side of the component 130, the protection effect on the component 130 is better, but such a setting requires a larger mass of the first protective member 120, which results in a larger mass of the distribution box 100 and is not conducive to the lightweight of the distribution box. By covering the connection portion between the first connection portion and the second connection portion with the first protective member 120, when the distribution box 100 is subjected to an external impact, the first protective member 120 can disperse the impact energy at the connection portion between the first connection portion and the second connection portion, protect the connection portion between the first connection portion and the second connection portion, and further ensure the stability of the connection portion between the first connection portion and the second connection portion, thereby ensuring the stability of the component 130. Thus, the mass of the first protective member 120 can be ensured not to be too large while protecting the component 130.

[0071] It can be understood that the first connection portion and the second connection portion are detachably connected to facilitate the removal of the component 130 from the housing 110 when repairing or replacing the component 130. The connection manner between the first connection portion and the second connection portion can be a threaded connection, a snap connection, or other detachable connection manners.

[0072] Exemplarily, it further includes at least one connecting member 140. At least one first connecting portion is a first connecting hole, and at least one second connecting portion is a second connecting hole. The connecting member 140 is connected to the second connecting hole through the first connecting hole. The first protective member 120 covers at least a part of the connecting member 140.

[0073] Further, both the first connecting hole and the second connecting hole are threaded holes, and the connecting member 140 is a screw.

[0074] In some embodiments, the distribution box 100 provided in the embodiments of the present application further includes a conductive member 150. A part of the conductive member 150 is located in the first accommodation cavity 111 and is electrically connected to each component 130. A part of the conductive member 150 extends outside the first accommodation cavity 111 and is used for electrically connecting to an external circuit component. The first protective member 120 covers at least a part of the conductive member 150.

[0075] Wherein, the components 130 and the external circuit components are electrically connected through the conductive member 150 to conduct current between the components 130 and transmit electrical energy to the external circuit components.

[0076] The first protective member 120 covers at least a part of the conductive member 150 to protect the conductive member 150 when the distribution box 100 is subjected to an external impact, thereby ensuring the stability of the conductive member 150.

[0077] Exemplarily, the conductive member 150 is a copper busbar.

[0078] On the basis of the above embodiments, the battery pack provided in the embodiments of the present application includes a battery tray 200 and at least one distribution box 100 provided on the battery tray 200.

[0079] Wherein, the structure of the distribution box 100 has been described in detail in the above embodiments and will not be elaborated here.

[0080] The battery pack provided by the embodiment of the present application. The power distribution box 100 fills the first protective member 120 in the first accommodation cavity 111, and the first protective member 120 covers at least part of the components 130, so that the first protective member 120 can form an anti-impact protective layer on the periphery of the components 130. Then, when the power distribution box 100 is subjected to external impact and vibration, the first protective member 120 can reduce the vibration and impact received by the housing 110 and the components 130, thereby protecting the housing 110 and the components 130, preventing the components 130 from being damaged or loosened, and improving the safety of the power distribution box 100. When it is necessary to repair or replace the components 130, the first protective member 120 can be made to flow out of the first accommodation cavity 111 through the channel on the housing 110, that is, the first protective member 120 around the components 130 can be removed. Thus, it is convenient to remove the first protective member 120, making the repair and replacement of the components 130 more convenient and improving the repair and replacement efficiency of the components 130.

[0081] Referring to Figure 4 and Figure 5 , in some embodiments, the battery pack provided by the embodiment of the present application further includes a second protective member 400. There is a second accommodation cavity 300 between the power distribution box 100 and the battery tray 200, and the second protective member 400 is filled in the second accommodation cavity 300. The second protective member 400 is used to protect the power distribution box 100. Wherein, there is a gap between the bottom of the power distribution box 100 and the battery tray 200 to form the second accommodation cavity 300.

[0082] The second protective member 400 can be the same as the first protective member 120.

[0083] Specifically, the second protective member 400 is filled in the second accommodation cavity 300. The power distribution box 100 is located above the battery tray 200, and the second protective member 400 covers the bottom surface of the power distribution box 100 to protect the power distribution box 100.

[0084] In specific implementation, the second protective member 400 includes a second non-Newtonian fluid with shear thickening characteristics.

[0085] Specifically, the second protective member 400 can be preformed first using a mold or other shaping tool, and then the second protective member 400 is placed in the second accommodation cavity 300. After a period of time, under the action of the cold flow characteristics of the second protective member 400, the second protective member 400 will automatically fill the second accommodation cavity 300.

[0086] The shear thickening property means that the viscosity of the second non-Newtonian fluid increases as the shear rate increases. When not subjected to external impact, the second non-Newtonian fluid is in a soft state. When the battery tray 200 is subjected to shear force, the viscosity of the second non-Newtonian fluid will increase rapidly, causing the second non-Newtonian fluid to change from a soft state to a solid state, and then the impact force can be absorbed and dispersed through the second protective member 400. The second protective member 400 can form an impact-resistant protective layer between the distribution box 100 and the battery tray 200 in a short time, reducing the impact and vibration received by the distribution box 100 and the battery tray 200, thereby protecting the distribution box 100 and the battery tray 200.

[0087] In a state without being impacted and vibrated, the second non-Newtonian fluid is in a soft state and will not affect the removal of the distribution box 100 from the battery tray 200, making the maintenance of the distribution box 100 more convenient.

[0088] Exemplarily, the second non-Newtonian fluid has good insulation performance. The second non-Newtonian fluid includes a solid-state organoborosiloxane polymer.

[0089] In some examples, the second protective member 400 further includes a heat-conducting filler or fillers with other properties to improve the performance of the second protective member 400.

[0090] In some embodiments, the battery pack provided by the embodiments of the present application further includes at least one bracket 500, and the bracket 500 is disposed on the battery tray 200.

[0091] The bracket 500 and the battery tray 200 jointly define a receiving groove 600, the distribution box 100 is located in the receiving groove 600, and the second protective member 400 is filled between the distribution box 100 and the side wall of the receiving groove 600.

[0092] Wherein, the bracket 500 can be welded to the battery tray 200 and connected to the side beam 210 of the battery tray 200 to form the receiving groove 600. By filling the second protective member 400 between the distribution box 100 and the side wall of the receiving groove 600, the second protective member 400 covers a part of the periphery of the distribution box 100, so that the distribution box 100 can be protected by the second protective member 400.

[0093] At the same time, the bracket 500 and the side beam 210 of a part of the battery tray 200 form the side wall of the receiving groove 600. The connection between the bracket 500 and the side beam 210 of the battery tray 200 makes the side wall of the receiving groove 600 all closed, thus preventing the second protective member 400 from flowing out of the receiving groove 600.

[0094] Exemplarily, the number of brackets 500 is two, and the two brackets 500 are respectively located on both sides of the distribution box 100. The height of the bracket 500 can be adaptively set according to actual requirements, and it is sufficient that the height of the bracket 500 is greater than or equal to the height of the battery tray 200.

[0095] In some examples, the distribution box 100 is connected to the bracket 500.

[0096] Based on the above-described embodiments, the electrical equipment provided in the embodiments of the present application includes an equipment body and a battery pack provided on the equipment body.

[0097] Exemplarily, the electrical equipment is a vehicle. During the driving of the vehicle, due to various factors such as the vibration of the vehicle during driving and the uneven road surface, vibrations and impacts will be imposed on the battery pack, resulting in damage or loosening of the distribution box 100 in the battery pack and the components in the distribution box 100, affecting the normal operation of the distribution box 100.

[0098] In the electrical equipment provided in the embodiments of the present application, the distribution box 100 fills the first accommodating cavity 111 with a first protective member 120, and the first protective member 120 covers at least part of the components 130, so that the first protective member 120 can form an anti-impact protective layer on the periphery of the components 130. Further, when the distribution box 100 is subjected to external impacts and vibrations, the first protective member 120 can reduce the vibrations and impacts received by the housing 110 and the components 130, thereby protecting the housing 110 and the components 130 and preventing the components 130 from being damaged or loosened, ensuring the normal operation of the distribution box 100.
