DETAILED DESCRIPTION OF EMBODIMENTS [0032] The technical schemes in the embodiments of the disclosure will be described clearly and completely below in combination with the drawings in the embodiments of the disclosure. Apparently, the described embodiments are only some of the embodiments of the disclosure, not all of the embodiments. Based on the embodiments of the disclosure, all of other embodiments obtained by those skilled in the field without creative effort belong to the protection scope of the disclosure. [0033] Embodiment 1 [0034] As shown in FIG. 1, the disclosure provides a battery housing 1, including a plastic housing body 10 and multiple mental plates 20. [0035] The plastic housing body 10 includes multiple side walls 11, an upper plate 12 and a bottom plate 13. The multiple side walls 11 are individually connected between the upper plate 12 and the bottom plate 13. The multiple side walls 11, the upper plate 12 and the bottom plate 13 together enclose to define a holding cavity 14 to hold a battery. For example, the battery is a storage battery, a solid lithium ion battery, a liquid lithium ion battery, etc. The plastic housing body 10 can be a housing component made of engineering plastic alloy. The plastic housing body 10 made of plastic greatly reduces a weight of the battery housing 1 and is easy to carry. 7 22001ZTD-CAP1 Date Recue/Date Received 2022-10-18 [0036] As shown in FIG. 1, the upper plate 12 is provided with a first through-hole 121 and a second through-hole 122; the plastic housing body 10 includes a first electrode connection terminal 15 and a second electrode connection terminal 16, which are respectively disposed in the first through- hole 121 and the second through-hole 122. In an illustrated embodiment of the disclosure, the first electrode connection terminal 15 and the second electrode connection terminal 16 protrude from the upper plate 12; the first electrode connection terminal 15 is connected to a positive electrode of the battery, and the second electrode connection terminal 16 is connected to a negative electrode of the battery. In another embodiment of the disclosure, the first electrode connection terminal 15 is connected to a negative electrode of the battery, and the second electrode connection terminal 16 is connected to a positive electrode of the battery. Polarity of the electrodes connected to the first electrode connection terminal 15 and the second electrode connection terminal 16 can be changed according to actual situation, which are not limited herein. [0037] In an illustrated embodiment of the disclosure, the multiple mental plates 20 are individually embedded in the multiple side walls 11. The metal plates 20 can be made of stainless steel or alloy to improve structural strength of the multiple side walls 11, thereby improving an overall structural strength of the battery housing 1. [0038] In an embodiment of the disclosure, as shown in FIG. 2, the multiple metal plates 20 include a first metal plate 21 and a second metal plate 22. The multiple side walls 11 include a first side wall 111 and a second side wall 112. [0039] As shown in FIG. 2, the first side wall 111 and the second side wall 112 are disposed opposite to each other and connected between the upper plate 12 and the bottom plate 13; the first metal plate 21 is embedded in the first side wall 111, and the second metal plate 22 is embedded in the second side wall 112. The first side wall 111 is provided with first mounting holes 1111, which extend from an outside of the first side wall 111 into the first metal plate 21. The 8 22001ZTD-CAP1 Date Recue/Date Received 2022-10-18 second side wall 112 is provided with second mounting holes 1121, which extend from an outside of the second side wall 112 into the second metal plate 22. In an illustrated embodiment of the disclosure, the first mounting holes 1111 and the second mounting holes 1121 extend into the first metal plate 21 and the second metal plate 22 respectively, namely that they are penetrated into the metal plates deeply. When a fixing plate or a connecting plate is fixed on a side wall through the mounting holes, a metal plate bears a torque force because the mounting holes extend into the metal plate. For example, the metal plates are embedded with screw holes, so that the mounting holes and the screw holes are connected as a whole structure. Therefore, the first fixing component 51 can be disposed on the first mounting holes 1111 to connect the first fixing component 51 to the first mental plate 21. Since the structural strength of the metal plate is higher than that of the plastic housing, the battery housing 1 is not easy to deform when the metal plate bears the torque force. Therefore, the structural strength of the battery housing 1 has been greatly improved. In another embodiment of the disclosure, the first mounting holes and the second mounting holes can extend into other position according to actual situation. For example, the first mounting holes and the second mounting holes can extend through the entire metal plate, which is not limited herein. [0040] In an embodiment of the disclosure, as shown in FIG. 3, the multiple side walls further include a third side wall 113 and a fourth side wall 114, which are disposed opposite to each other, connected between the upper plate 12 and the bottom plate 13, and connected between the first side wall 111 and the second side wall 112. [0041] As shown in FIG. 3, a first extension part 211 and a second extension part 212 are disposed on opposite ends of the first metal plate 21 respectively; the first extension part 211 extends from an end of the first metal plate 21 adjacent to the third side wall 113 to an end of the third side wall 113 adjacent to the first side wall 111; the second extension part 212 extends from another end 9 22001ZTD-CAP1 Date Recue/Date Received 2022-10-18 of the first metal plate 21 adjacent to the fourth side wall 114 to an end of the fourth side wall 114 adjacent to the first side wall 111. The third side wall 113 is provided with third mounting holes 1131, which extend from an outside of the third side wall 113 into the first extension part 211; and the fourth side wall 114 is provided with fourth mounting holes 1141, which extend from an outside of the fourth side wall 114 into the second extension part 212. The structure of the second metal plate 22 is similar to that of the first metal plate 21, which can be referred. The first mental plate 21 is provided with the first extension part 211 and the second extension part 212, which are corresponding to the third mounting holes 1131 and the fourth mounting holes 1141; the third mounting holes 1131 extend from the outside of the third side wall 113 into the first extension part 211 and the fourth mounting holes 1141 extend from the outside of the fourth side wall 114 into the second extension part 212. Therefore, when multiple battery housings 1 need to be connected to form a power source with greater electric power, the connecting plate can be installed on the third mounting holes 1131 and the fourth mounting holes 1141. At the same time, since the third mounting holes 1131 and the fourth mounting holes 1141 extend into the extension parts of the first metal plate 21, the metal plate bears the torque force, so that the structural strength of the battery housing 1 is higher. The second metal plate 22 is also provided with two extension parts, and the structure of the second metal plate 22 is symmetrical with that of the first metal plate 21. Therefore, the structure of the second mental plate 22 can refer to that of the first mental plate 21; the details will not be repeated here. [0042] As shown in FIG. 3, the multiple metal plates 20 further include a third metal plate 23 and a fourth metal plate 24, and the third metal plate 23 is embedded in another end of the third side wall 113 adjacent to the bottom plate 13. The fourth metal plate 24 is embedded in another end of the fourth side wall 114 adjacent to the bottom plate 13. The third side wall 113 is provided with fifth mounting holes 1132, which extend from the outside of the third side wall 22001ZTD-CAP1 Date Recue/Date Received 2022-10-18 113 into the third metal plate 23. The fourth side wall 114 is provided with sixth mounting holes 1142, which extend from the outside of the fourth side wall 114 into the fourth metal plate 24. Since the mounting holes can extend into the metal plates, the metal plates bear the torque force of fixation or connection. Since the structural strength of the metal plates is higher than that of the plastic housing body, when the metal plates bear the torque force, the structure of the battery housing 1 is not easy to deform, and the structural strength of the battery housing 1 is higher. [0043] In an embodiment of the disclosure, as shown in FIG. 2 and FIG. 4, the battery housing 1 further includes a first fixing component 51, first mounting components 52 and a second fixing component 53, second mounting components 54. The first fixing component 51 is provided with first mounting through-holes 511, and the second fixing component 53 is provided with second mounting through-holes 531. The first fixing component 51 is abutted against the first side wall 111, and the first mounting components 52 are successively penetrated into the first mounting through-holes 511 and the first mounting holes 1111 to connect the first fixing component 51 to the first side wall 111. The second fixing component 53 is abutted against the second side wall 112, and the second mounting components 54 are successively penetrated into the second mounting through-holes 531 and the second mounting holes 1121 to connect the second fixing component 53 to the second sidewall 112. [0044] In an illustrated embodiment of the disclosure, as shown in FIG. 4, the first fixing component 51 and the second fixing component 53 are L-shaped metal plates. The L-shaped metal plate includes a first fixing plate and a second fixing plate, which are perpendicular to each other to form an L shape. The second fixing plate of the first fixing component 51 is provided with the first mounting through-holes 511. The second fixing plate of the second fixing component 53 is provided with the second mounting through-holes 531. Namely, when the L-shaped metal plate is abutted against the first side wall 111, the first 11 22001ZTD-CAP1 Date Recue/Date Received 2022-10-18 mounting through-holes 511 are disposed on the second fixing plate. When the L-shaped metal plate is abutted against the second side wall 112, the second mounting through holes 531 are disposed on the second fixing plate. The first fixing plate is provided with a hanging fixing part, which facilitates carrying or fixing according to actual needs. When the battery housing 1 needs to be fixed on the wall or the ground, the hanging fixing part of the first fixing plate is provided with a connecting component. For example, the connecting component can be a screw. When the battery housing 1 needs to be carried, the connecting component disposed on the hanging fixing part of the first fixing plate can be a hanging rope. The first mounting components 52 or the second mounting components 54 are disposed on the second fixing plate of the L-shaped metal plate. For example, the first mounting components 52 and the second mounting components 54 can be screws. The screws are fixed with the first metal plate 21 through the first mounting through-holes 511 and the first mounting holes 1111, which makes the first fixing component 51 be abutted against the first side wall 111. Therefore, when the first fixing component 51 is fixed on the first side wall 111 through the first mounting components 52, the first mental plate 21 bears the torque force. The connection mode of the second fixing component 53 can refer to that of the first fixing component 51; the details will not be repeated here. [0045] In an embodiment of the disclosure, as shown in FIG. 3, the battery housing 1 further includes a third fixing component 61, third mounting components 62, a fourth fixing component 63 and fourth mounting components 64. The third fixing component 61 is provided with third through-holes 611, and the fourth fixing component 63 is provided with fourth through-holes 631. The third fixing component 61 is abutted against the third side wall 113, and the third mounting components 62 are successively penetrated into the third mounting through-holes 611 and the third mounting holes 1131 correspondingly to connect the third fixing component 61 to the third side wall 113. The fourth 12 22001ZTD-CAP1 Date Recue/Date Received 2022-10-18 fixing component 63 is abutted against the fourth side wall 114, and the fourth mounting components 64 are successively penetrated into the fourth mounting through-holes 631 and the fourth mounting holes 1141 correspondingly to connect the fourth fixing component 63 to the fourth side wall 114. For example, the third fixing component 61 and the fourth fixing component 63 can be a fixing plate and the fixing plate can be an L-shaped metal plate. The third mounting components 62 and the fourth mounting components 64 can be screws. The connection mode of the third fixing component 61 and the third mounting components 62, and the connection mode of the fourth fixing component 63 and the fourth mounting components 64 in the embodiment can refer to the connection mode of the first fixing component 51 and the first mounting components 52 above, the details will not be repeated here. [0046] In an illustrated embodiment of the disclosure, as shown in FIG. 5, the upper plate 12 is provided with a protruding part 123, and a protruded height of the protruding part 123 is higher than that of the first electrode connection terminal 15 and the second electrode connection terminal 16. In the embodiment of the disclosure, although the first electrode connection terminal 15 and the second electrode connection terminal 16 protrude from the upper plate 12, a protruded height does not exceed that of the protruding part 123. For one reason, accidental electric shock can be prevented. When a user accidentally drops conductive objects onto the upper plate 12 of the battery housing 1, the conductive objects directly slide out nor reserve on the upper plate 12 because the protruded height of the protruding part 123 is higher than that of the first electrode connection terminal 15 and the second electrode connection terminal 16. Therefore, the user will not be in danger of electric shock when picking up the conductive objects due to contact with the first electrode connection terminal 15 and the second electrode connection terminal 16. For another reason, when objects fall onto the upper plate 12 of the battery housing 1, the first electrode connection terminal 15 and the second electrode connection terminal 16 can be 13 22001ZTD-CAP1 Date Recue/Date Received 2022-10-18 protected from direct collision with the falling objects, which in turn causes damage to the first electrode connection terminal 15 and the second electrode connection terminal 16. [0047] In an illustrated embodiment of the disclosure, as shown in FIG. 4 to FIG. 5, the protruding part 123 and the upper plate 12 enclose to define a cavity, which is used to place a battery management chip. The battery management chip is electrically connected with the battery placed in the holding cavity. The positive and negative electrodes of the battery are connected with the battery management chip, and then the battery management chip is electrically connected with the first electrode connection terminal 15 and the second electrode connection terminal 16. For example, the battery management chip can be a battery management system, which is mainly used to detect and control voltage, current, temperature and other parameters of the battery, and also to provide low-voltage, overvoltage, overcurrent, short circuit, over temperature, low temperature and other protection for the battery. The protruding part 123 is also provided with a communication port and a switch button. The switch button is used to control connection and disconnection between the first electrode connection terminal 15 and the second electrode connection terminal 16 in the battery housing 1 and the positive and negative electrodes of the battery, thereby controlling start or stop of the power source when the battery is installed in the battery housing. The communication port is used for communicating with the battery management chip. For example, the communication port is a serial port, and the serial port can be a cluster communication port (COM). [0048] In an illustrated embodiment of the disclosure, as shown in FIG. 6, the first mounting holes 1111 are disposed on edges of the first side wall 111. For example, the first mounting holes 1111 are disposed on four edges of the first side wall 111, which can meet different needs of the battery housing. For example, when the user needs to carry the battery housing 1, the first mounting holes 1111 can be disposed on the edge of the first side wall 111 adjacent to the 14 22001ZTD-CAP1 Date Recue/Date Received 2022-10-18 upper plate 12, and then the connecting component is installed on the first mounting holes 1111. The connecting component is provided with a hanging part. An assembly of the hanging part, the connecting component and the first mounting holes makes the battery housing 1 portable. When the battery housing 1 needs to be fixed on the wall, the first mounting holes 1111 can be disposed on the edge of the first side wall 111 adjacent to the fourth side wall 114, and then the battery housing 1 can be fixed on the wall through a cooperation of the first mounting holes 1111 and the fixing component by installing the fixing component such as the screw on the first mounting holes 1111. Specific positions of the first mounting holes 1111 can be disposed on different edges of the first side wall 111 according to the actual situation, which can meet different needs of the user in different scenes. [0049] In an illustrated embodiment of the disclosure, as shown in FIG. 6 to FIG. 7, a concave part 1112 is disposed on a middle position of the outside of the first side wall 111. The concave part 1112 is provided with seventh mounting holes 1113, which extend from the outside of the first side wall 111 into the first metal plate 21. The battery housing 1 further includes a pairing plate 71 and fifth mounting components 72. The pairing plate 71 is provided with fifth mounting through-holes 711, which corresponds to the seventh mounting holes 1113. The fifth mounting components 72 are successively penetrated into the fifth mounting through-holes 711 and the seventh mounting holes 1113 to connect the pairing plate 71 to the concave part 1112 of the first side wall 111. In an embodiment of the disclosure, the pairing plate 71 can be a rectangular metal plate, and the fifth mounting components 72 can be screws. In the embodiment of the disclosure, the pairing plate 71 can be used as an ornament by installing the pairing plate 71 on the concave part 1112 of the first side wall 111. When multiple battery housings 1 need to form an integral structure, the pairing plate 71 is disposed on the first mounting holes 1111 of the first side walls 111 of the multiple battery housings 1. Therefore, two of the multiple battery housings 1 22001ZTD-CAP1 Date Recue/Date Received 2022-10-18 form an integral structure by connecting the pairing plate.
