[0080] Among them, the seat body 111 is provided with the mating portion 112 and the housing 121 of the plug 120 on the side away from the box body 210 in the vertical direction, and the side surface of the mating portion 112 away from the seat body 111 (i.e. the upper surface of the mating portion 112) is defined as the first end 1121 and the second end 1122 at both ends in the first horizontal direction, respectively, and in the direction extending from the first end 1121 to the second end 1122, since the upper surface of the mating portion 112 is arranged obliquely, the distance between the side surface of the mating portion 112 away from the seat body 111 and the seat body 111 in the vertical direction decreases. It can be understood that the upper surface of the mating portion 112 can be a plane or a curved surface.

[0081] For example, the side surface of the seat portion 111 away from the fitting portion 112 can be horizontally arranged, and the side surface of the fitting portion 112 away from the seat portion 111 can be formed as an arc surface, and the included angle between the tangent of the arc surface and the side surface of the seat portion 111 away from the fitting portion 112 gradually increases in the direction from the first end 1121 to the second end 1122; or the side surface of the fitting portion 112 away from the seat portion 111 can be formed as an inclined surface, that is, the side surface of the fitting portion 112 away from the seat portion 111 is arranged at an included angle with the side surface of the seat portion 111 away from the fitting portion 112.

[0082] Of course, it can be understood that as long as the distance between the side surface of the fitting portion 112 away from the seat portion 111 and the seat portion 111 in the first direction decreases in the direction from the first end 1121 to the second end 1122, the specific shape of the side surface of the fitting portion 112 away from the seat portion 111 is not limited here.

[0083] The shell 121 is arranged around the fitting portion 112 in the circumferential direction of the fitting portion 112 and extends in the first direction, and the shell 121 and the fitting portion 112 jointly define a cavity with one end open, the pin 122 is arranged in the fitting portion 112 and is used for electrical connection with the counter-arrangement, the shell 121 can protect the pin 122, which is conducive to reducing the risk of damage to the pin 122, and the shell 121 can guide the plug 120 when the plug 120 is matched with the counter-arrangement, which is conducive to improving the convenience of matching the plug 120 with the counter-arrangement.

[0084] For example, the shell 121 can be configured as an elliptical cylinder, a circular cylinder or a polygonal cylinder (for example, a square cylinder).

[0085] Further combined Figure 3 and Figure 5The shell 121 is provided with a discharge hole 123 on the side corresponding to the second end 1122 in the first horizontal direction. The discharge hole 123 can be arranged through the shell 121 in the first horizontal direction, so that the inside and outside of the shell 121 are connected through the discharge hole 123. When the sundries (such as dust or snow water, etc.) enter the shell 121 through the open end of the shell 121, the distance between the upper surface of the fitting part 112 and the seat part 111 in the up-down direction decreases in the direction extending from the first end 1121 to the second end 1122, that is, the upper surface of the fitting part 112 extends downward toward the discharge hole 123, so that the upper surface of the fitting part 112 can guide the sundries to the second end 1122, and the sundries can be further discharged from the shell 121 through the discharge hole 123, which is beneficial to prevent the accumulation of sundries in the shell 121, thereby reducing the risk of affecting the battery replacement efficiency of the battery device 200 due to the accumulation of sundries in the battery replacement connector 100, and reducing the cleaning frequency of the battery replacement connector 100, facilitating the maintenance of the battery replacement connector 100.

[0086] Please refer to Figure 5 The bottom position of the hole wall of the discharge hole 123 can be flush with the lowest position of the upper surface of the fitting part 112, so that the fitting part 112 does not block the discharge hole 123, which is beneficial to reduce the risk of blockage of the discharge hole 123 and improve the smoothness of the discharge of the sundries through the discharge hole 123.

[0087] The discharge hole 123 can be provided with 1, 2, 3, or 4, 4 or more, and the specific number of discharge holes 123 can be determined according to the size of the discharge hole 123, the size of the shell 121, and the structural strength requirement of the shell 121, etc., which is not limited here.

[0088] In the technical solution, the matching portion 112 is arranged on the seat body 111, and the upper surface of the matching portion 112 extends downward toward the second end 1122, so that the matching portion 112 can guide the sundries toward the second end 1122. The discharge hole 123 is arranged on the shell 121 and located at the second end 1122, so that after the sundries are guided by the side surface of the matching portion 112 away from the seat body 211 to the second end 1122, the sundries can be discharged from the battery replacement connector 100 through the discharge hole 123, preventing the accumulation of sundries in the battery replacement connector 100 and reducing the risk of affecting the battery replacement efficiency of the battery device 200. The hole of the discharge hole 123 is flush with the second end 1122, preventing the matching portion 112 from blocking the discharge hole 123, improving the effect of discharging the sundries through the discharge hole 123, preventing the discharge hole 123 from being blocked, and facilitating the introduction of air resistance by the battery replacement connector 100, increasing the friction force when the battery replacement connector 100 is matched with the matching device, and improving the matching reliability of the battery replacement connector 100.

[0089] Please refer to Figure 4 to Figure 6 In the embodiment of the present application, the shell 121 is connected with the matching portion 112 without gap. For example, the shell 121 and the matching portion 112 are an integral part.

[0090] In the technical solution, the shell 121 is connected with the matching portion 112 without gap, so that the gap between the shell 121 and the matching portion 112 is avoided, and the sundries falling into the gap cannot be guided by the matching portion 112 to the discharge hole 123, so that the sundries in the shell 121 can be completely removed and discharged, improving the effect of discharging the sundries and the cleaning convenience of the battery replacement connector 100, and reducing the cleaning frequency of the battery replacement connector 100.

[0091] For example, the inner contour shape of the orthographic projection of the shell 121 on the horizontal plane can be matched with the outer contour shape of the orthographic projection of the matching portion 112 on the horizontal plane, and the shell 121 is arranged around and tightly attached to the matching portion 112 along the circumferential direction of the matching portion 112, so as to realize the gapless connection between the shell 121 and the matching portion 112.

[0092] Please refer to Figure 4 In the embodiment of the present application, the distance between the upper surface of the matching portion 112 and the lower surface of the seat body 111 in the up-down direction continuously decreases along the direction from the first end 1121 to the second end 1122. For example, the upper surface of the matching portion 112 extends smoothly as an inclined surface or a curved surface.

[0093] In the technical solution, the distance between the side surface of the fitting portion 112 away from the seat portion 111 and the side surface of the seat portion 111 away from the fitting portion 112 in the first direction continuously decreases along the direction from the first end 1121 to the second end 1122, which facilitates the processing of the fitting portion 112, and there is no dead angle on the upper surface of the fitting portion 112, which is beneficial to reduce the risk of accumulation of sundries on the fitting portion 112, thereby improving the guiding effect of the fitting portion 112 on the sundries and improving the discharging effect of the sundries.

[0094] As shown in Figure 4 , the lower surface of the seat portion 111 can be horizontally arranged, the upper surface of the fitting portion 112 is arranged at an angle with the lower surface of the seat portion 111, and the angle can be a constant value or gradually change, that is, the upper surface of the fitting portion 112 can be a plane, an arc surface or a stepped inclined surface, and in the up-down direction, the upper surface of the fitting portion 112 gradually extends to the direction close to the seat portion 111 from the first end 1121 to the second end 1122.

[0095] Please refer to Figure 4 In the embodiment of the present application, the side surface of the fitting portion 112 away from the seat portion 111 is formed as an inclined surface, and the angle between the inclined surface and the side surface of the seat portion 111 away from the fitting portion 112 is α, 5°≤α≤45°.

[0096] In the technical solution, by making the angle α between the inclined surface and the side surface of the seat portion 111 away from the fitting portion 112 satisfy 5°≤α≤45°, the guiding effect of the side surface of the fitting portion 112 away from the seat portion 111 on the sundries is improved, and at the same time, the arrangement space of the fitting portion 112 in the up-down direction is reduced, which is beneficial to reduce the size of the battery swap connector 100 in the up-down direction.

[0097] Exemplarily, the angle α between the inclined surface and the side surface of the seat portion 111 away from the fitting portion 112 can be 5°, 6°, 7° and 8°, etc., wherein when α<5°, the guiding effect of the inclined surface on the sundries is poor, and part of the sundries is easy to accumulate in the shell 121, when α>45°, the arrangement space of the fitting portion 112 is large, which is easy to cause the size of the battery swap connector 100 to increase, and at the same time, it is not convenient for the production and assembly of the battery swap connector 100.

[0098] Wherein, α satisfies 30°≤α≤45°, in order to improve the guiding effect of the inclined surface on the sundries, and at the same time, it is beneficial to reduce the arrangement space required by the fitting portion 112, and it is beneficial to improve the mechanical stability of the fitting portion 112 and reduce the risk of damage of the fitting portion 112.

[0099] Please refer to Figure 3 and Figure 5In the embodiments of the present application, the number of the discharge holes 123 is three or more, and the plurality of discharge holes 123 are arranged at intervals.

[0100] In the above technical solution, by setting the number of the discharge holes 123 to three or more, the efficiency of discharging the sundries from the battery replacement connector 100 is improved, thereby further reducing the cleaning frequency of the battery replacement connector 100. By arranging the plurality of discharge holes 123 at intervals, the weakening of the shell 121 caused by processing the discharge holes 123 is appropriately reduced, the structural strength of the shell 121 is reliably arranged, and the risk of damage to the shell 121 is reduced.

[0101] For example, the number of the discharge holes 123 can be three, four, or five, and the plurality of discharge holes 123 can be arranged at intervals along the second horizontal direction in sequence. The second horizontal direction is perpendicular to the first horizontal direction. It can be understood that the specific number of the discharge holes 123 and the arrangement manner can be determined according to actual production requirements, which are not limited here.

[0102] It should be noted that the "second horizontal direction" can be understood as the length direction of the seat body 111, and the specific direction is shown in FIGS. 1 and 2. Figure 3 Figure 4

[0103] Please refer to FIGS. 1 and 2. Figure 3 In some embodiments, the diameter of the discharge hole 123 is d, and 6mm≤d≤12mm.

[0104] It can be understood that the diameter d of the discharge hole 123 can be 6mm, 7mm, 8mm, or 9mm, and the specific diameter size of the discharge hole 123 can be determined in actual production and processing, which is not limited here.

[0105] In the above technical solution, by setting the diameter d of the discharge hole 123 to satisfy 6mm≤d≤12mm, the risk of clogging of the discharge hole 123 is reduced, the efficiency of discharging the sundries through the discharge hole 123 is improved, and the structural strength of the shell 121 is prevented from being poor due to the too large diameter of the discharge hole 123, thereby reducing the risk of damage to the shell 121.

[0106] In some embodiments, the number of the discharge holes 123 is three or more, and the diameter of the discharge hole 123 is d, and 6mm≤d≤12mm.

[0107] ​​In the technical solution, the number of the discharge holes 123 is set to three or more, the plurality of discharge holes 123 are arranged at intervals, and the diameter d of the discharge holes 123 satisfies 6mm≤d≤12mm, which is beneficial to improve the efficiency of discharging the sundries from the battery swap connector 100, thereby further reducing the cleaning frequency of the battery swap connector 100, reducing the risk of blockage of the discharge holes 123, and improving the structural strength of the shell 121 and reducing the risk of damage to the shell 121.

[0108] In the embodiments, the shape of the discharge hole 123 is not limited, for example, the discharge hole 123 can be a circular hole, an oval hole, a polygonal hole, etc.

[0109] In some embodiments, when the battery swap connector 100 is installed on the surrounding wall 213 of the battery device 200, the angle α can be 30°, and the shell 121 can be provided with three discharge holes 123 with a diameter of 10mm, which is beneficial to improve the processing convenience of the battery swap connector 100, improve the discharging effect of the sundries through the discharge holes 123, and improve the size and number of the discharge holes 123 while ensuring the structural strength of the shell 121, thereby improving the cooperation reliability of the battery swap connector 100.

[0110] Please refer to Figure 5 and Figure 6 In the embodiments, the shell 121 includes two first side walls 1211 arranged opposite to each other along a first horizontal direction and two second side walls 1212 arranged opposite to each other along a second horizontal direction, the two first side walls 1211 are both flat plate structures and are arranged in parallel, the two second side walls 1212 are both curved plate structures and are convex away from each other, the discharge hole 123 is formed in one of the first side walls 1211, and the second horizontal direction is perpendicular to the first horizontal direction.

[0111] For example, the two first side walls 1211 are arranged opposite to each other and at intervals along the first horizontal direction, the two second side walls 1212 are arranged opposite to each other and at intervals along the second horizontal direction, and the adjacent first side wall 1211 and second side wall 1212 are connected, the first side wall 1211 is a flat plate structure, the two second side walls 1212 are curved plate structures, and the two second side walls 1212 are convex away from each other in a direction extending away from the first side wall 1211 from the position where the second side wall 1212 is connected to the two first side walls 1211, and the discharge hole 123 is formed in the first side wall 1211 adjacent to the second end 1122.

[0112] In the technical solution, the two first side walls 1211 are formed as flat plate structures to facilitate the processing and arrangement of the first side walls 1211, and the discharge holes 123 are formed on the first side walls 1211 to facilitate the processing of the discharge holes 123; the two second side walls 1212 are formed as curved plate structures protruding away from each other, and since the structural strength of the curved plate structure is relatively greater than that of the flat plate structure, the structural strength of the shell 121 is improved, and the space inside the shell 121 is increased, which facilitates the arrangement of the pins 122 and other structures in the shell 121.

[0113] For details, refer to Figure 6 In the embodiment, the pins 122 are multiple and arranged along the second horizontal direction, and the spacing between each pin 122 and the two first side walls 1211 in the first horizontal direction is not equal.

[0114] For details, refer to Figure 6 The pins 122 can be two, which are arranged along the second horizontal direction, and for details, refer to Figure 4 In the first horizontal direction, the pin 122 is arranged relatively close to the first side wall 1211 on the same side of the first end 1121, that is, the spacing between the pin 122 and the first side wall 1211 on the same side of the first end 1121 is less than the spacing between the pin 122 and the first side wall 1211 on the same side of the second end 1122, which facilitates the reduction of foreign matter falling into the gap between the pin 122 and the first side wall 1211 on the same side of the first end 1121, facilitates the guiding of the foreign matter by the fitting part 112 in the direction towards the second end 1122, thereby facilitating the discharge of the foreign matter, and facilitating the determination of the direction when the mating structure of the station end is matched with the battery swap connector 100, which improves the matching convenience of the battery swap connector 100.

[0115] Of course, the number of pins 122 can be determined according to actual production requirements, for example, the number of pins 122 can also be three, and the specific number of pins 122 is not limited here.

[0116] In the technical solution, the multiple pins 122 are arranged along the second horizontal direction, which facilitates the prevention of the malfunction of the battery swap connector 100 caused by the mutual contact between the pins 122, and facilitates the electrical connection between the pins 122 on the battery swap connector 100 and the mating structure of the station end, and by making the spacing between each pin 122 and the two first side walls 1211 in the first horizontal direction not equal, the effect of discharging foreign matter is improved, and the positioning when the battery swap connector 100 is matched with the mating structure is facilitated, which improves the matching convenience and accuracy of the battery swap connector 100.

[0117] For details, refer to Figure 4 to Figure 6In the embodiment of the present application, the battery replacement connector 100 further comprises a protection wall 130, each pin 122 corresponds to a protection wall 130, the protection wall 130 is arranged around the corresponding pin 122 and is spaced between the pin 122 and the shell 121, in the up-down direction, the protection wall 130 and the pin 122 are both protruding from the end of the shell 121 away from the seat body 111, and the protection wall 130 and the pin 122 are both protruding from the end of the seat body 111 away from the shell 121. It can be seen that the protection wall 130 and the pin 122 are both protruding from the upper end of the shell 121, and the protection wall 130 and the pin 122 are both protruding from the upper end of the seat body 111.

[0118] Exemplarily, the protection wall 130 can be formed as a sleeve, which is arranged around the outer periphery of the pin 122 and is spaced from the shell 121 and the pin 122 respectively, and the first end 1121 of the protection wall 130 and the pin 122 in the first direction penetrates the mounting seat 110, and the other end of the protection wall 130 and the pin 122 extends from the shell 121 in the first direction.

[0119] In the above technical solution, by arranging the protection wall 130, the protection wall 130 plays a role in protecting the pin 122, which is conducive to reducing the risk of damage to the pin 122, and in the process of electrically connecting the pin 122 with the mating structure, the protection wall 130 can play a role in guiding and positioning to a certain extent, which is conducive to improving the convenience and accuracy of the battery replacement connector 100 and the mating structure. In the up-down direction, by making the protection wall 130 and the pin 122 extend from the mounting seat 110 and the shell 121 respectively, it is conducive to improving the convenience of electrical connection of the battery replacement connector 100.

[0120] In the embodiment of the present application, the battery replacement connector 100 further comprises a protective cover, which is movably connected or detachably connected with the seat body 111 or the shell 121, and the protective cover is used to cover the end of the shell 121 away from the seat body 111.

[0121] For example, the protective cover and the seat body 111 can be provided with a clamping cooperation structure, so that the protective cover and the seat body 111 are detachably connected, and the protective cover can be detachably connected with the shell 121 by covering and cooperating with the shell 121. When the battery replacement connector 100 is not used, the protective cover is covered on the end of the shell 121 away from the seat body 111 (i.e. the upper end of the shell 121), so as to close the open end of the shell 121 and prevent foreign matter from falling into the shell 121. When the battery replacement connector 100 needs to be matched with the mating structure, the protective cover can be detached from the shell 121 and fixed to the seat body 111 through the clamping cooperation structure, so as to prevent the protective cover from being lost. After the battery replacement is completed, the protective cover can be removed from the seat body 111 and covered on the open end of the shell 121, so as to close the shell 121.

[0122] Alternatively, the protective cover can be rotatably mounted on the open end of the shell 121 by a rotating shaft. When the battery replacement connector 100 is not needed, the protective cover is arranged at the end of the shell 121 away from the seat body 111 to close the open end of the shell 121, preventing foreign matter from falling into the shell 121. When the battery replacement connector 100 needs to be aligned with the alignment structure, the protective cover can be driven to rotate relative to the shell 121 to open the open end of the shell 121, so that the battery replacement connector 100 can be aligned with the alignment structure.

[0123] Here, the disassembly or opening of the protective cover relative to the shell 121 can be manually operated, or can also be automatically operated by a mechanical hand or the like device.

[0124] It can be understood that the connection mode of the protective cover with the seat body 111 and the shell 121 is not specifically limited in the present application. For example, the protective cover can be detachably connected with the shell 121 by a threaded connection, or the protective cover can be movably connected with the seat body 111 by a rotating connection, while realizing the detachable connection of the protective cover with the shell 121.

[0125] In the above technical solution, by arranging the protective cover at the end of the shell 121 away from the seat body 111, the risk of foreign matter falling into the shell 121 is reduced, thereby further reducing the frequency of cleaning the battery replacement connector 100, and further reducing the cleaning and maintenance cost of the battery replacement connector 100.

[0126] Please refer to Figure 2 In a second aspect, the embodiments of the present application also provide a battery device 200, which comprises a box body 210, a battery monomer 220, and the above-mentioned battery replacement connector 100. The battery monomer 220 is arranged in the box body 210, the battery replacement connector 100 is arranged in the box body 210, and the mounting seat 110 is connected with the box body 210.

[0127] In the above technical solution, since the battery device 200 is provided with the above-mentioned battery replacement connector 100, and the battery replacement connector 100 is not easy to accumulate foreign matter, the battery replacement efficiency of the battery device 200 is improved, and the cleaning and maintenance cost of the battery device 200 is reduced.

[0128] In some embodiments, the battery device 200 further comprises a partition beam (not shown), which is arranged in the box body 210 and separates the internal space of the box body 210 into a containing cavity and an electrical cavity. It can also be understood that the partition beam separates the containing cavity and the electrical cavity, and the battery monomer 220 is arranged in the containing cavity.

[0129] For example, the electrical cavity can be used to arrange electrical components, which can be relays for controlling the charging and discharging process of the battery device 200, contactors for controlling the connection and disconnection of the battery device 200 with the vehicle circuit, and sensors for real-time monitoring and control of the current flow inside the battery device 200, etc.

[0130] In the above technical solution, by arranging the partition beam to separate the accommodation cavity and the electrical cavity, when the battery monomer 220 in the accommodation cavity leaks, the partition beam can hinder the liquid from flowing into the electrical cavity, which is beneficial to reduce the risk of pollution of the electrical components due to the liquid flowing into the electrical cavity, thereby reducing the risk of short circuit of the electrical components and improving the safety of the battery device 200.

[0131] The battery replacement connector 100 is arranged corresponding to the electrical cavity, which facilitates the electrical connection between the battery replacement connector 100 and the corresponding components in the electrical cavity. The battery replacement connector 100 serves as the electrical interface of the battery device 200, which can be matched with the corresponding structure on the charging facility (such as a charging pile) to enable the battery device 200 to perform power transmission with the charging facility, thereby realizing the battery replacement of the battery device 200.

[0132] In the embodiments of the present application, the battery replacement connector 100 is recessed relative to the inner surface of the box body 210.

[0133] For example, the battery replacement connector 100 is arranged on the inner surface of the box body 210, and the battery replacement connector 100 is recessed from the inner surface of the box body 210 towards the outer surface of the box body 210. It can also be understood that the battery replacement connector 100 is recessed from the inner surface of the box body 210 towards the direction away from the cavity (the cavity is composed of the accommodation cavity and the electrical cavity).

[0134] In the above technical solution, by recessing the battery replacement connector 100 relative to the inner surface of the box body 210, the occupied space of the battery replacement connector 100 in the box body 210 is reduced, which is beneficial to increase the space in the box body 210 for arranging the battery monomer 220, thereby improving the energy density of the battery device 200.

[0135] Please refer to Figure 2 In the embodiments of the present application, the box body 210 includes a top wall 211, a bottom wall 212, and a surrounding wall 213. The surrounding wall 213 connects the top wall 211 and the bottom wall 212, and the battery replacement connector 100 is arranged on the top wall 211, the bottom wall 212, or the surrounding wall 213.

[0136] Exemplarily, the box body 210 can be configured as a square, the top wall 211 and the bottom wall 212 are oppositely arranged, and the surrounding wall 213 can be connected with at least one of the top wall 211 and the bottom wall 212. For example, the box body 210 can include a first box 210a and a second box 210b. The first box 210a includes the top wall 211 and the surrounding wall 213 which is arranged around the top wall 211 in the circumferential direction of the top wall 211 and connected with the top wall 211. The second box 210b includes the bottom wall 212 and the surrounding wall 213 which is arranged around the bottom wall 212 in the circumferential direction of the bottom wall 212 and connected with the bottom wall 212. That is, the first box 210a and the second box 210b are both formed as a hollow structure with one end open. The surrounding wall 213 of the first box 210a and the surrounding wall 213 of the second box 210b are both provided with a flange. When the first box 210a and the second box 210b are buckled and matched, the threaded connecting piece (such as a screw or a bolt) is arranged through the flange to fixedly connect the first box 210a and the second box 210b, so as to realize that the surrounding wall 213 connects the top wall 211 and the bottom wall 212.

[0137] Of course, it can be understood that the structure and shape of the box body 210 are not limited to this, as long as the surrounding wall 213 can connect the top wall 211 and the bottom wall 212. The specific structure and shape of the box body 210 can be determined according to actual production requirements, which is not limited here.

[0138] The battery swap connector 100 can be installed on the top wall 211, the bottom wall 212 or the surrounding wall 213 of the box body 210, so as to improve the arrangement flexibility of the battery swap connector 100, and facilitate to improve the production and assembly efficiency of the battery device 100.

[0139] It can be understood that the specific installation position of the battery swap connector 100 can be determined according to actual production requirements and the arrangement position of the battery device 200 on the vehicle, which is not limited here.

[0140] Please refer to Figure 1 , in a third aspect, the application further provides a power utilization device 1000, which comprises the above-mentioned battery device 200, and the battery device 200 is used for storing or providing electric energy.
