[0029] Now, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention.

[0030] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present invention or its application or use.

[0031] Technologies and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies and devices should be regarded as part of the specification.

[0032] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0033] It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

[0034] According to an embodiment of the present invention, there is provided a battery system that can be quickly installed and replaced, as Figures 1 - 10 shown. In the embodiment of the present invention, it includes a housing 1 of an external device, a box body 2 installed in the housing 1, and a cover plate 3 covering the box body 2. Cavity structures are provided inside both the housing 1 and the box body 2. Among them, the cavity structure of the housing 1 is used to accommodate the box body 2. A battery cell module and a battery management system can be installed inside the cavity of the box body 2. The battery cell module can preferably be arranged at the bottom of the cavity, and the battery management system can preferably be installed on the side of the cover plate inside the cavity. Additionally, the external device can be a battery compartment of an electric device such as an AGV robot, a scooter, or an electric vehicle. It can be understood that the electric device needs to be provided with a cavity structure for placing the battery. For example, to place the box body 2 structure of the present invention, so the housing 1 can be a structure arranged on a trolley, that is, there is no need to separately provide the housing 1, and thus only the box body 2 needs to be placed for battery replacement.

[0035] In an embodiment of the present invention, as Figures 3 - 10 , a middle column 21 is provided on the box body 2. The middle column 21 is a hollow structure and is set as a first through hole 22; a second through hole 31 is provided on the cover plate 3 corresponding to the first through hole; a fixing hole 11 is provided at the bottom of the housing 1 corresponding to the first through hole 22, and an internal thread is provided along at least a section of the opening of the fixing hole 11 facing downwards; the first through hole 22, the second through hole 31, and the fixing hole 11 are on the same central axis and are communicated to form a sliding channel. The handle assembly 4 includes a sliding rod 41 and a handle 42 provided at one end of the sliding rod 41. An external thread is provided at the other end of the sliding rod 41, and this end extends into the sliding channel and moves along the sliding channel and is screwed into the fixing hole 11.

[0036] In this embodiment, a middle column 21 is provided on the box body 2. The middle column 21 is provided with a first through hole 22 with openings at both ends. The cover plate 3 is provided with a second through hole 31 corresponding to the first through hole 22. At the same time, a fixing hole 11 is provided at the bottom of the bin body 1 corresponding to the position of the first through hole 22. In this way, the second through hole 31 and the fixing hole 11 are on the same central axis and communicate with each other to form a sliding channel. One end of the sliding rod 41 of the handle assembly 4 can extend into the sliding channel and move on the sliding channel, and the other end can extend out of the sliding channel, and the sliding rod 41 is controlled by the handle 42. In addition, the end of the sliding rod 41 extending into the sliding channel is provided with an external thread, and at the same time, an internal thread is provided along the downward extension of the fixing hole 11. The sliding rod can be fixed on the bin body 1 through the cooperation of the external thread and the internal thread.

[0037] In an embodiment of the present invention, the present invention has two modes, one is a fastening mode and the other is a handle mode. When the present invention is in the fastening mode, the sliding rod 41 extends into the fixing hole 11, so as to fix the box body 2 on the bin body 1; when the present invention is in the handle mode, the sliding rod 41 does not extend into the fixing hole 11, that is, it is not threadedly connected to the fixing hole 11, and the box body 2 is not fixed on the bin body 1. In this way, the switching between the two modes is simple. Only by rotating the sliding rod 41 and screwing the sliding rod 41 into the fixing hole 11, the battery is in the fastening mode at this time, so as to fasten the battery. For example, if the bracket of the vehicle is used as the bin body, the battery can be fastened on the vehicle without using additional screws or other components for fixing; at the same time, only by screwing out the sliding rod 41 in the reverse direction and screwing the sliding rod 41 out of the fixing hole 11, the battery is in the handle mode at this time, so as to separate the box body of the battery from the bin body. For example, if the bracket of the vehicle is used as the bin body, the battery can be separated from the vehicle. When the battery needs to be maintained or replaced, the maintenance or replacement work can be carried out quickly, reducing potential safety hazards.

[0038] It should be noted that the box body 2 is different from the ordinary box body structure. It is a hollow cylindrical box body structure. The cavity structure inside the box body is an annular internal space. The box body 2 includes an inner annular side wall and an outer annular side wall. A bottom wall is provided on one of the inner annular side wall and the outer annular side wall, and the inner annular side wall and the outer annular side wall are connected through the bottom wall. Therefore, the inner annular side wall is the middle column 21. The present invention cleverly adopts the middle column 21 with a hollow structure, and designs the handle assembly 4. A fixing hole with an internal thread is designed on the bin body 1, and the sliding rod 41 of the handle assembly 4 extends into the fixing hole, so as to fix the box body 2 on the bin body 1 well, that is, to fix the box body 2 on the electric device with the bin body 1. The structure is simple and convenient for the replacement and maintenance of the box body 2.

[0039] In addition, as Figure 2 shown, the handle 42 and the sliding rod 41 can be connected by a pin 43, and there is no need to use welding for fixing, which is convenient and safe.

[0040] It should be noted that the handle 42 is not set by welding and is not installed on the box body, but on the sliding rod. In fact, the handle 42 does not belong to the components of the box body, and there is no risk of air leakage caused by welding, which improves the protection of the box body.

[0041] In an embodiment of the present invention, the first through hole 11 includes a first section through hole 22a and a second section through hole 22b. The diameter of the second section through hole 22b is larger than that of the first section through hole 22a. A blocking wall 23 is formed at the connection of the first section through hole 22a and the second section through hole 22b. A step 411 extending outward along the side of the sliding rod 41 is provided on the sliding rod 41, and the step 411 cooperates with the blocking wall 23.

[0042] The sliding rod 41 is a straight rod and can slide along the sliding channel. At a certain position of the sliding rod 41, for example, at the upper position of the sliding rod 41, a step 411 is provided. The step 411 extends outward along the side of the sliding rod 41, and the step 411 plays an interference role to prevent the sliding rod 41 from sliding out of the sliding channel when sliding. At the same time, the first through hole 11 includes a first section through hole 22a and a second section through hole 22b. The diameter of the first section through hole 22a is smaller, and the diameter of the second section through hole 22b is larger. The step 411 is located in the second section through hole 22b, and the step 411 moves in the second section through hole 22b. Since the diameter of the first section through hole 22a is smaller than that of the second section through hole 22b, a blocking wall 23 is formed at the connection of the first section through hole 22a and the second section through hole 22b. The blocking wall 23 can interfere with the step 411, so that the step 411 can only slide in the second section through hole 22b. In this way, for limiting, in the handle mode, the bin body 1 and the box body 2 can be separated, and the handle assembly 4 is limited in the sliding channel. The box body 2 can be lifted by the handle, which is more rapid when maintenance and replacement are required, and there is no need to use external tools to take out the box body 2.

[0043] In an embodiment of the present invention, a raised fixing column 12 is provided at the bottom of the bin body 1, and the fixing hole 11 is provided on the fixing column 12. Or, the bottom of the bin body 1 is a plane, and the fixing hole 11 extends downward along this plane. The fixing hole 11 is provided at the bottom of the bin body 1. At this time, there are at least two ways to set the fixing hole 11. One way is to form a raised fixing column 12 on the bottom of the bin body 1, and the fixing hole 11 is provided on the fixing column 12. The sliding rod 41 is threadedly connected to the fixing column 12, and the box body 2 is thus fixed to the bin body 1. Another way is that the fixing hole 11 is directly provided on the bottom plane of the bin body 1, that is, the fixing hole 11 is formed by extending downward along the bottom plane of the bin body 1. This embodiment only discloses two ways to set the fixing hole 11. Of course, there are also other ways. As long as the fixing hole is provided at the bottom of the bin body 1 and is threadedly connected to the sliding rod 41, it is within the protection scope of the present invention.

[0044] In addition, when the fixing hole 11 is provided on the fixing post 12, the first through hole 22 further includes a third through hole segment 22c communicating with the second through hole segment 22b, and the third through hole segment 22c houses the fixing post 12. The first through hole 22 communicates with the fixing hole 11, facilitating the insertion of the sliding rod 41 into the fixing hole 11. The lower segment of the first through hole 22 is set as the third through hole segment 22c, and the third through hole segment 22c communicates with the second through hole segment 22b. Among them, the diameter of the third through hole segment 22c can be set according to the external threaded end of the sliding rod 41. For example, since the third through hole segment 22c needs to house the fixing post 12, the diameter of the third through hole segment 22c can be larger than the diameter of the second through hole segment 22b, or the diameter of the third through hole segment 22c can be equal to the diameter of the second through hole segment 22b, which can be set according to actual needs. For example, if the external threaded end of the sliding rod 41 is narrowed, and the diameter of this end is smaller than the diameter of the middle part of the sliding rod 41, this end can be smoothly screwed into the fixing post 12. At this time, when the diameter of the third through hole segment 22c is equal to or larger than the diameter of the second through hole segment 22b, it can be set according to actual needs.

[0045] In an embodiment of the present invention, a gasket 5 is provided between the box body 2 and the cover plate 3. The gasket 5 can play a sealing role, sealing the gap between the box body 2 and the cover plate 3. The gasket 5 is in a ring structure. For example, it can be a ring-shaped circular structure, or it can be a ring-shaped square structure, depending on the structural design of the box body 2 and the cover plate 3. At the same time, the material of the gasket 5 is a plastic material, such as materials like PP, PEK, PTFE, PVDF, PEEK, etc. The gasket 5 can be sealed by the extrusion of interference fit.

[0046] Furthermore, a flange nut 32 is provided corresponding to the first through hole 22, and the upper end of the middle post 21 is threadedly connected to the flange nut 32. It can be understood that the connection between the flange nut 32 and the middle post 21 can form a T-shaped bolt structure, which can achieve quick installation. At the same time, the cover plate 3 can be recessed downward at the position where the flange nut 32 is installed to form an empty groove, which can be used to house the flange nut 32, reducing the height of the handle 42 protruding from the plane of the cover plate 3 and controlling the overall height of the battery.

[0047] In an embodiment of the present invention, an upper sealing ring 33 and a lower sealing ring 34 are further included, which are respectively arranged corresponding to the inside and outside of the box body 2 for sealing. Since the box body 2 is a cavity structure, it is necessary to seal both the inside and outside of the cavity structure. Among them, the cover plate 3 covers the box body 2, and the sealing gasket 5 is used for sealing between the cover plate 3 and the box body 2. In addition, the middle column 21 passes through the cover plate 3, so it is also necessary to seal between the middle column 21 and the cover plate 3. Both the upper sealing ring 33 and the lower sealing ring 34 are annular structures. The upper sealing ring 33 is sleeved on a part of the structure of the middle column 21 located inside the box body 2, and the lower sealing ring 34 is sleeved on a part of the structure of the middle column 21 extending outside the box body. Among them, the upper sealing ring 33 is located between the flange nut 32 and the cover plate 3, and is sealed by the interference fit between the cover plate 3 and the flange nut 32. The lower sealing ring 34 is located inside the box body. An annular boss structure is formed outward at the end of the middle column 21 close to the cover plate 3. This annular boss structure can be used to support the lower sealing ring 34, and the lower sealing ring 34 is located between the annular boss structure and the back of the cover plate 3, and the two can squeeze the lower sealing ring 34 to seal. Through the sealing gasket 5, the upper sealing ring 33 and the lower sealing ring 34, the sealing of the box body 2 can be realized.

[0048] It should be noted that the box body 2 is a hollow cylindrical box body structure, the inner annular side wall is the middle column 21, and the first through hole 22 is not communicated with the cavity structure of the box body 2, and the first through hole 22 in the middle column 21 does not need to be sealed.

[0049] At the same time, the box body 2 is a cavity structure, and a battery cell module 6 and a battery management system 7 are installed in this cavity structure. The battery cell module 6 can be divided into multiple battery cells. Since the cavity structure is an annular cavity, the battery cell module 6 can be designed according to the actual structure of the inner cavity. The battery management system 7 can be connected to the battery cell module 6 and is used to control functions such as heat dissipation, power supply and safety of the telecommunication module 6.

[0050] The battery disclosed in the present invention includes a storage body and a box body. There is a battery cell module inside the box body. The storage body can be extended into a battery storage structure of an electric device. The storage body is used to accommodate the box body. A fixing hole is opened at the bottom of the storage body, and the inner wall of the fixing hole has internal threads. The box body is provided with a middle column, and the middle column is provided with a first through hole. One end of the sliding rod of the handle assembly is provided with external threads, and this end can extend into the first through hole to cooperate with the internal threads at the bottom of the storage body, so as to connect the box body and the storage body through the sliding rod. The entire installation process is very simple, and only the sliding rod needs to be rotated and screwed into the storage body to assemble the box body; when it is necessary to take out the box body, only the sliding rod needs to be rotated in the reverse direction, and it is convenient to take out. Compared with the traditional installation method, there is no need to prepare tools such as sleeves for disassembly and assembly, which speeds up the maintenance and replacement work; in addition, the handle is not installed in a welding manner and is not installed on the box body, but on the sliding rod. In fact, it does not belong to the components of the box body and will not cause the risk of air leakage due to welding, improving the protection of the box body.

[0051] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
