Description

Technical Field

[0001] The present invention relates to an inspection instrument, and more specifically, to an intelligent inspection instrument for a battery pack that is convenient to connect. Background Art

[0002] The battery inspection instrument, also known as the ITB915 battery monitoring and management system, is a dedicated monitoring and management system developed for 2V, 6V, and 12V valve-regulated lead-acid batteries used in UPS power systems and battery systems. It is widely used in important places and departments such as power, communication, petrochemical, finance, and railway. The battery inspection instrument is a device for real-time and comprehensive on-line detection and management of the batteries in the power supply system.

[0003] In the prior art, most inspection instruments are installed on the brackets of the battery pack through an installation frame. When the installation frame is connected to the bracket, the arranged wires are easily caught by the bracket. Once the wires are pulled during later disassembly or use, the outer skin of the wires will be damaged. Therefore, there is an urgent need to propose an intelligent inspection instrument for a battery pack that is convenient to connect. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent inspection instrument for a battery pack that is convenient to connect, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, an intelligent inspection instrument for a battery pack that is convenient to connect is provided. It includes an inspection instrument body and an installation frame arranged around the inspection instrument body. The inspection instrument body is installed on the bracket of the battery pack through the installation frame. An interface end is provided on the same side of the inspection instrument body, and all the interface ends are arranged in a horizontal row. The interface end is used to connect with the single-row wires extended from the battery pack. A wire embedding frame is rotatably arranged on the access side of the installation frame where the interface end is located. When the installation frame fits with the bracket, the wire embedding frame affected by the bracket closes with the installation frame to embed the wires connected to the interface end on the installation frame.

[0006] As a further improvement of this technical solution, the wire embedding frame includes a cross plate and side plates arranged at both ends of the cross plate. A transfer seat is provided at the end of the side plate, and the side plate is rotatably connected to the installation frame through the transfer seat.

[0007] As a further improvement of this technical solution, a resistance member for restricting the unfolding angle of the side plate is installed on the transfer seat, so that the included angle formed between the unfolded side plate and the installation frame is less than 90 degrees.

[0008] As a further improvement of the present technical solution, a wire embedding assembly is provided below the cross plate. The wire embedding assembly includes a plurality of wire embedding groups and an integral plate connecting the plurality of wire embedding groups. Each wire embedding group includes a first wire embedding plate and a second wire embedding plate. A wire inlet slot is opened on the cross plate at the gap between the first wire embedding plate and the second wire embedding plate, where:

[0009] A receiving groove is provided on the access side of the mounting frame at the interface end.

[0010] As a further improvement of the present technical solution, an inlet wire slot body with an inlet wire opening and an outlet wire opening is formed on one side of the first wire embedding plate and the second wire embedding plate near the wire inlet slot. The inlet wire opening is located on the side where the wire inlet slot is located, and the outlet wire opening is located on the side far from the wire inlet slot. The diameter of the inlet wire opening is larger than that of the outlet wire opening. A wire bundling slot is provided on one side of the inlet wire slot body at the outlet wire opening.

[0011] As a further improvement of the present technical solution, an expansion slot is opened on the integral plate on the side where the wire bundling slot is located. The outer end of the expansion slot extends away from the wire bundling slot to provide sufficient bending space for the circuit.

[0012] As a further improvement of the present technical solution, a back slot is opened on one side of the first wire embedding plate and the second wire embedding plate close to the mounting frame during rotation.

[0013] As a further improvement of the present technical solution, the resistance member is a "V"-shaped elastic plate. One end of the elastic plate is fixedly connected to the side plate, and the other end is fixedly connected to the mounting frame. In the case where the side plate is not stressed, the elastic plate can keep the side plate in a state of 30 - 45 degrees.

[0014] As a further improvement of the present technical solution, a plurality of clamping plates are provided on the stressed side of the cross plate avoiding the wire inlet slot.

[0015] As a further improvement of the present technical solution, a limiting assembly is provided at the top of the mounting frame. The limiting assembly includes a limiting post which is slidably connected to the mounting frame. A flange is provided at one end of the limiting post away from the bracket during installation. A limiting spring is fixedly connected between the flange and the mounting frame bracket. In the case of not being stressed, the end of the limiting post contacting the bracket is on the same axis as the virtual rotating shaft.

[0016] Compared with the prior art, the beneficial effects of the present invention:

[0017] 1. In the intelligent battery pack inspection instrument that is convenient for connection, the buried wire frame under the action of the bracket is closed with the installation frame to bury the wire connected to the interface end on the installation frame. In this way, the connected wire will pass along the surface of the installation frame through the bracket, which not only solves the problem that it is inconvenient to connect the wire hanging on the bracket, but also further restricts the single-row wire, improves the connection stability between the wire and the interface end, and will not fall off due to pulling.

[0018] 2. In the intelligent battery pack inspection instrument that is convenient for connection, all wires are clamped into the corresponding wire troughs, then the length of the wires is controlled, and then the horizontal plate is actively pressed down for a buried wire simulation to see if the length and position of the wires are appropriate. If not, continue to adjust the wire length or position. When all wires are appropriate, then connect the wires to the interface end. At this time, installation will not require secondary installation due to insufficient wire length or inaccurate position.

[0019] 3. In the intelligent battery pack inspection instrument that is convenient for connection, one end of the limiting column in contact with the bracket is on the same axis as the virtual rotating shaft when not under force. In this way, once the installation frame rotates to a state horizontal with the bracket, the limiting column will contact the bracket for prompting.

[0020] 4. In the intelligent battery pack inspection instrument that is convenient for connection, the elastic limit of the limiting spring is equal to the elastic limit of the resistance member. In this way, after contact, when the inspection instrument body is pushed horizontally, in an environment with the same limit, it is more convenient to control the force, and the force for pushing the inspection instrument body will not need to be adjusted due to different elastic limits.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0043] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0044] The present invention provides an intelligent battery pack inspection instrument that is convenient for connection. Please refer to Figure 1 , the inspection instrument includes an inspection instrument body 100 and an installation frame 200 arranged on the periphery of the inspection instrument body 100. The inspection instrument body 100 is installed on the bracket of the battery pack through the installation frame 200. The difference between the inspection instrument of the present invention and the ordinary inspection instrument is that: all the interface ends connected to the lines extended from the battery pack are arranged on the same side of the inspection instrument body 100, and all the interface ends are arranged in a horizontal row, so that the interface ends can correspond one by one when connecting to the single-row lines. Although the single-row arrangement can effectively reduce the possibility of line intersection, when the installation frame 200 is connected to the bracket, the arranged lines are easily caught by the bracket. Once the lines are pulled during later disassembly or use, the outer skin of the lines will be damaged. To solve this problem, the present invention rotatably arranges a wire embedding frame 300 on the access side of the installation frame 200 where the interface ends are located. When the installation frame 200 fits with the bracket, the wire embedding frame 300 affected by the bracket closes with the installation frame 200 to embed the lines connected to the interface ends on the installation frame 200. In this way, the connected lines will pass along the surface of the installation frame 200 through the bracket, which not only solves the problem that the lines are caught on the bracket and is not convenient for line connection, but also further restricts the single-row lines, improves the stability of the connection between the lines and the interface ends, and will not fall off due to pulling.

[0045] Figure 3The first embodiment of the present invention is shown. In the figure, the wire embedding frame 300 includes a cross plate 330 and side plates 310 arranged at both ends of the cross plate 330. A transfer seat 320 is provided at the end of the side plate 310. The side plate 310 is rotatably connected to the installation frame 200 through the transfer seat 320. In addition, a resistance member for restricting the unfolding angle of the side plate 310 is installed on the transfer seat 320, so that the included angle formed between the unfolded side plate 310 and the installation frame 200 is less than 90 degrees, preferably 30 - 45 degrees. Because when it is less than 30 degrees, the access side space of the interface end is too narrow due to the restriction of the cross plate 330, which is not convenient for wiring. When it exceeds 45 degrees, it is not convenient for the cross plate 330 and the bracket to bear force. And when it is greater than 90 degrees, the cross plate 330 cannot fit the installation frame 200 after being stressed.

[0046] During specific use, the wire is passed through from below the cross plate 330, then connected to the interface end through the cross plate 330, and all the wires and the corresponding interface ends are connected in this way in sequence. After the connection, the inspection instrument body 100 is installed, that is, the installation frame 200 is fixed on the bracket. When the installation frame 200 approaches the bracket, the cross plate 330 is in an unfolded state under the action of its own gravity. Therefore, the first part to contact the bracket is the cross plate 330. The side plate 310 rotates due to the force on the cross plate 330. When the installation frame 200 fits with the bracket, the cross plate 330 also fits with the installation frame 200. At this time, the cross plate 330 can bury the wire on the surface of the installation frame 200, allowing the wire to pass along the surface of the installation frame 200 through the bracket;

[0047] Returning to Figure 3 , another implementation method of wire pre - embedding is disclosed in this embodiment. On the basis of the above structure, in order to perfectly pre - embed the wire on the installation frame 200, a wire embedding component 340 is provided below the cross plate 330 in the figure. Please refer to Figure 5 As shown, the wire embedding component 340 includes a plurality of wire embedding groups and an integral plate 343 connecting the plurality of wire embedding groups. The wire embedding group includes a first wire embedding plate 341 and a second wire embedding plate 342. A wire inlet slot 330A is opened on the cross plate 330 at the gap between the first wire embedding plate 341 and the second wire embedding plate 342. In addition, Figure 4 a receiving groove 200A is provided on the installation frame 200 at the access side of the interface end. When the cross plate 330 fits with the installation frame 200, it can be completely received in the receiving groove 200A. Then, the first wire embedding plate 341 and the second wire embedding plate 342 are used to restrict the wire, so that the wire is pre - embedded completely according to the gap direction between the first wire embedding plate 341 and the second wire embedding plate 342, and is completely received in the receiving groove 200A in cooperation with the first wire embedding plate 341 and the second wire embedding plate 342.

[0048] Figure 5 and Figure 6The second embodiment of the present invention is shown. On the side of the first wire embedding plate 341 and the second wire embedding plate 342 close to the wire inlet slot 330A, a wire inlet slot body 341A with a wire inlet and a wire outlet is formed. The wire inlet is located on the side where the wire inlet slot 330A is located, and the wire outlet is located on the side far from the wire inlet slot 330A. Moreover, the diameter of the wire inlet is larger than that of the wire outlet. A wire bundling slot 341B is arranged on the side of the wire inlet slot body 341A where the wire outlet is located.

[0049] During use, the wire passes through the wire inlet slot 330A and enters the wire inlet of the wire inlet slot body 341A, then passes through the wire inlet slot body 341A and is clamped into the wire bundling slot 341B from the wire outlet. The wire bundling slot 341B supports the wire by means of the integral plate 343. Since the diameter of the wire outlet is reduced, the wire after being clamped is restricted. The difference between this embodiment and the first embodiment in the implementation manner lies in the wire connection method. Since this embodiment can initially fix the wire by utilizing the restricting ability of the wire bundling slot 341B, it is not necessary to directly connect the wire to the interface end after the wire passes through the cross plate 330. Instead, all the wires are clamped into the corresponding wire bundling slots 341B, then the length of the wire is controlled, and then the cross plate 330 is actively pressed down for a wire embedding simulation to check whether the length and position of the wire are appropriate. If not, continue to adjust the wire length or position. When all the wires are appropriate, then connect the wires to the interface end. At this time, when installing again, there will be no need for secondary installation due to the problems of insufficient wire length or inaccurate position.

[0050] In addition, Figure 5 an expansion slot 343A is opened on the integral plate 343 on the side where the wire bundling slot 341B is located. The outer end of the expansion slot 343A extends towards the side far from the wire bundling slot 341B to provide sufficient bending space for the wire, so as to adapt to the wires extending from different positions.

[0051] Figure 7 The third embodiment of the present invention is shown. When the first wire embedding plate 341 and the second wire embedding plate 342 rotate, a back slot 341C is opened on the side close to the installation frame 200 (that is, the back side of the first wire embedding plate 341 and the second wire embedding plate 342). The back slot 341C forms a gap with a triangular cross-section on the back side of the first wire embedding plate 341 and the second wire embedding plate 342 by means of the wire inlet slot body 341A and the wire bundling slot 341B;

[0052] Combined with Figure 8The working principle of the above structure is described. Based on the second embodiment, the inserted line is restricted at the wire duct groove 341B. During installation, the horizontal plate 330 is pressed, driving the first wire embedding plate 341 and the second wire embedding plate 342 to rotate (i.e., in the direction shown by arrow a in the figure) until the first wire embedding plate 341 and the second wire embedding plate 342 are completely accommodated in the accommodation groove 200A. At this time, a channel for guiding the line is formed between the gap and the accommodation groove 200A to bury the line in the accommodation groove 200A ( Figure 8 The dotted part in is the line), and finally it bypasses the bracket through the expansion slot 343A.

[0053] It should be noted that both the first wire embedding plate 341 and the second wire embedding plate 342 are flexible structures on the side close to the gap. One is to protect the line, and the other is to facilitate the clamping of the line and the later removal of the line using the flexible part.

[0054] Figure 11 and Figure 12 Figure shows the fourth embodiment of the present invention. In this embodiment, the resistance member in the first embodiment is mainly disclosed. The resistance member can be a resistance block, but the resistance block can only block the side plate 310 in one direction. Therefore Figure 11 Another embodiment of the resistance member is shown in. In the figure, the resistance member is a "V"-shaped elastic plate 311. One end of the elastic plate 311 is fixedly connected to the side plate 310, and the other end is fixedly connected to the mounting frame 200. When the side plate 310 is not stressed, the elastic plate 311 can keep the side plate 310 in a state of 30 - 45 degrees. Compared with the resistance block, it can block the side plate 310 in two directions without external force, so as to facilitate the installation of the line in the second embodiment;

[0055] The resistance member can also be a torsion spring 321. Figure 12 An annular groove 320A is opened inside the adapter seat 320. The torsion spring 321 is fixed in the annular groove 320A, and the end of the torsion spring 321 is also fixedly connected to the side plate 310. The torsion spring 321 also blocks the side plate 310 by using the action of elastic force, and its principle is the same as that of the elastic plate 311.

[0056] Figure 2 Figure shows the fifth embodiment of the present invention. Through holes are opened at the four corners of the mounting frame 200 in the figure, and the mounting frame 200 is fixed on the bracket by using the through holes in cooperation with external fixing members, such as screws, bolts, pins, and buckles, etc.

[0057] Considering that a part of the inspection instrument body 100 protrudes, during installation, the inspection instrument body 100 needs to be aligned with the slots on the bracket, and then pushed horizontally to make the installation frame 200 contact the bracket, and then the fixing of the installation frame 200 and the bracket is completed. However, such an operation is very cumbersome, and when the circuit is connected, it is very difficult for the inspection instrument body 100 to be aligned with the slots. Therefore, during installation, the side of the inspection instrument body 100 where the circuit is connected is first placed on the bracket, and then the part placed on the bracket forms a virtual rotating shaft to make the inspection instrument body 100 rotate. During the rotation process, the installation frame 200 gradually fits the bracket. The premise for realizing this process is that the slots reserve enough space for the inspection instrument body 100 to rotate. That is to say, in this embodiment, it is not necessary to open through holes at the four corners of the installation frame 200, but only to open through holes at the corners on the side of the installation frame 200 away from the interface end of the inspection instrument body 100;

[0058] However, once the slots reserve space, it will leave a hidden danger for the stability of the later connection. Because once the fastening of the through hole connection decreases, the inspection instrument body 100 will shake in the reserved space. For this reason, this embodiment discloses another embodiment. Please refer to Figure 9 and Figure 10 As shown, on the basis of the fourth embodiment, a plurality of clamping plates 331 are arranged on the side of the cross plate 330 that is stressed and away from the wire inlet slot 330A;

[0059] During use, please refer to Figure 11 As shown, first place the clamping plate 331 on the bracket. Since the side plate 310 is in the unfolded state at this time, the virtual rotating shaft is pre-positioned by using the side plate 310 to cooperate with the clamping plate 331, and then the inspection instrument body 100 is rotated (the rotation direction is arrow b) to make the installation frame 200 approach the bracket. When the installation frame 200 and the bracket are in a horizontal state, then push the inspection instrument body 100 to make it horizontally enter the slot. At this time, the inspection instrument body 100 can enter the slot without reserving space. While the inspection instrument body 100 enters, the side plate 310 is gradually accommodated in the accommodation groove 200A to complete the embedding of the circuit and the fitting operation of the installation frame 200 and the bracket.

[0060] In addition, in order to prompt the state where the installation frame 200 and the bracket are kept horizontal, please refer to Figure 11As shown, a limiting component 210 is provided at the top of the installation frame 200. The limiting component 210 includes a limiting post 211 which is slidably connected to the installation frame 200. At one end of the limiting post 211 away from the bracket during installation, a flange 213 is provided. A limiting spring 212 is fixedly connected between the flange 213 and the bracket of the installation frame 200. In the case of no force, the end of the limiting post 211 contacting the bracket is on the same axis as the virtual rotating shaft. In this way, once the installation frame 200 rotates to a state horizontal with the bracket, the limiting post 211 will contact the bracket for prompting;

[0061] It should be noted that the elastic limit of the limiting spring 212 is equal to the elastic limits of the elastic plate 311 and the torsion spring 321. In this way, when the inspection instrument body 100 is horizontally pushed after contact, in an environment with the same limit, it is more convenient to control the force, and the force for pushing the inspection instrument body 100 will not be adjusted due to different elastic limits.

[0062] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
