Description

Technical Field

[0001] This application relates to the technical field of battery devices, and particularly to a connection structure, a battery device, and an electrical device. Background Art

[0002] In the prior art, when assembling a male head and a female head, users usually rely on experience or visual observation to confirm whether the male head and the female head are assembled in place. This judgment method has a very high error rate, resulting in frequent situations where the male head and the female head are not assembled in place. Summary of the Utility Model

[0003] In view of the above problems, this application provides a connection structure, a battery device, and an electrical device to improve the accuracy of assembling connection joints and avoid the situation where the male head and the female head of the connection structure are not assembled in place.

[0004] In a first aspect, this application provides a connection structure, including:

[0005] A male head;

[0006] A female head, provided with a first insertion portion and a jack for inserting the male head;

[0007] A locking member, movably installed on the female head along a first direction;

[0008] An identification member, provided with a second insertion portion, and the second insertion portion is used for plugging and matching with the first insertion portion along a second direction; the second direction intersects with the first direction;

[0009] When the depth of insertion of the male head into the jack reaches a preset value, the locking member can move from a first position to a second position; in the first position, the locking member can limit the identification member along the second direction; in the second position, the locking member can lock the male head and release the limitation of the second direction on the identification member;

[0010] The second direction is parallel to the insertion direction of the male head.

[0011] In the technical solution of the embodiment of the present application, before the male head is inserted into the through hole of the female head, the identification member and the locking member are both pre-installed on the female head. Specifically, the locking member and the identification member are located on the same side of the female head. The second insertion portion of the identification member is inserted and mated with the first insertion portion of the female head along the second direction. The locking member passes through the identification member and is movably connected to the female head. At this time, the position where the locking member is located is the first position, and the locking member can limit the identification member along the second direction. When the male head and the female head are assembled, that is, the male head is inserted into the through hole of the female head. After the depth of the insertion jack of the male head reaches a preset value, the locking member moves from the first position along the first direction towards the direction close to the central axis of the female head. When it cannot move any further, the locking member moves to the second position. At this time, the locking member is locked with the female head, and at the same time, the male head is also locked in the through hole of the female head. During the process of the locking member moving from the first position towards the direction close to the central axis of the female head, the locking member will gradually move away from the identification member. After the locking member moves to the second position, the second-direction limit on the identification member can be released, so that the identification member can slide along the second direction and disengage from the female head. Compared with the way that the identification member is clamped to the locking member and can be disengaged along the first direction under the action of the locking member, in the present application, the identification member slides relative to the female head along the second direction to disengage, canceling the clamping between the identification member and the locking member, which can reduce the processing difficulty of the workpiece and reduce the occurrence of the phenomenon that the identification member is difficult to disengage due to clamping. The technical solution of the embodiment of the present application is provided with an identification member and a locking member. When the male head and the female head are assembled in place, the identification member can slide along the second direction and disengage from the female head, and the locking member can no longer move relative to the female head. By observing these two objective phenomena, the user can confirm that the male head and the female head have been assembled in place, thereby avoiding the situation where the male head and the female head are not assembled in place and improving the assembly accuracy.

[0012] In an alternative embodiment, the first insertion portion includes a slot, one end of the slot along the second direction has an opening, the second insertion portion includes a plugging block, and the plugging block can be inserted into or disengaged from the slot through the opening.

[0013] The first insertion portion is configured as a slot, and the second insertion portion is configured as a plugging block. When the identification member is pre-installed on the female head, the plugging block can be inserted into the slot through the opening of the slot. When the locking member moves to the second position, the plugging block can be disengaged from the slot through the opening of the slot. Through the adaptation of the plugging block and the slot, the locking member and the female head are connected by plugging, and the structure is simple.

[0014] In an alternative embodiment, a plurality of the slots are provided, and the plurality of slots are spaced apart on the outer periphery of the female head;

[0015] A plurality of the plugging blocks are provided, and the plurality of plugging blocks are arranged in one-to-one correspondence with the plurality of slots.

[0016] By providing multiple groups of slots and plug-in blocks that cooperate with each other and are arranged at intervals, the stability of the connection between the identification member and the female head is ensured.

[0017] In an alternative embodiment, the female head includes a first body and a second body. The second body is sleeved on one end of the first body, and the first engaging portion and the jack are both provided on the second body.

[0018] When assembling the female head, by sleeving the second body on one end of the first body and providing the first engaging portion and the jack on the second body, the female head is formed and the first engaging portion and the jack on the female head are realized.

[0019] In an alternative embodiment, a first engaging portion is provided at one end of the first body, and a second engaging portion is further provided on the second body. The first engaging portion engages with the second engaging portion;

[0020] One of the first engaging portion and the second engaging portion is a snap, and the other is a snap hole.

[0021] Through the snap-fit cooperation between the first engaging portion and the second engaging portion, the connection between one end of the first body and the second body is realized. In addition, by configuring one of the first engaging portion and the second engaging portion as a snap and the other as a snap hole, the engagement between the first engaging portion and the second engaging portion is realized.

[0022] In an alternative embodiment, the second body includes an outer cylinder, an inner cylinder, a connecting portion, and a sealing member. The inner cylinder is disposed inside the outer cylinder, the connecting portion is connected between the outer cylinder and the inner cylinder, the first engaging portion is provided on the outer cylinder, and the jack is provided on the inner cylinder;

[0023] The end face of the first body abuts against the connecting portion;

[0024] The sealing member is disposed on the inner cylinder, and the sealing member is used to seal the gap between the male head and the first body when the male head is inserted into the jack.

[0025] The inner cylinder, the connecting portion, and the outer cylinder are connected in sequence from the inside to the outside. By providing the first engaging portion on the outer cylinder, the plug-in connection between the second body and the identification member is realized. By providing the jack on the inner cylinder, the connection between the second body and the male head is realized. In addition, by providing the sealing member on the inner cylinder, the gap between the male head and the first body is sealed, thereby ensuring the sealing performance between the male head and the female head.

[0026] In an alternative embodiment, the identification member is further provided with a through hole through which the locking member can pass;

[0027] At the first position, the locking member is partially located within the through-hole to be able to limit the movement of the identification member in the second direction;

[0028] At the second position, the locking member is away from the through-hole to release the limitation of the second direction on the identification member.

[0029] By providing the through-hole, the locking member can pass through the identification member from the through-hole, and then surround a partial outer peripheral side of the female head and be connected to the female head.

[0030] In an alternative embodiment, the identification member is further provided with a pulling portion for a user to remove the identification member from the female head.

[0031] By providing the pulling portion, when the male head and the female head are assembled, it is convenient for the user to remove the identification member from the female head through the pulling portion, providing a force application point for the user to remove the identification member and facilitating the user's operation.

[0032] In an alternative embodiment, an annular groove is provided on the outer peripheral surface of the male head; the locking member includes a clamping platform;

[0033] At the second position, the clamping platform is inserted into the annular groove.

[0034] When the depth of insertion of the male head into the jack reaches a preset value, the annular groove and the clamping platform of the locking member will be in the same plane. The locking member can be moved from the first position to the second position by the insertion of the clamping platform into the annular groove, so that the inner diameter of the clamping platform of the locking member abuts against the outer diameter of the annular groove of the male head. Since the inner diameter of the clamping platform is not greater than the outer diameter of the annular groove of the male head, when the clamping platform is inserted into the annular groove, the male head will not continue to move along the through-hole of the female head. At this time, the locking member is locked with the male head, and at the same time, the locking member is also locked with the female head to lock the male head and the female head, thus completing the assembly of the male head and the female head.

[0035] In an alternative embodiment, the locking member further includes a connecting arm connected to the clamping platform. A first catch is provided at one end of the connecting arm away from the clamping platform; a first card slot is further provided on the female head;

[0036] When the locking member is in the first position, the first catch is inserted into the first card slot.

[0037] By providing a first card slot on the female head and correspondingly providing a first catch on the locking member, when the first catch of the locking member engages with the first card slot of the female head, the locking member is exactly in the first position at this time, thus playing a role in positioning the locking member, enabling the locking member to quickly reach the first position during installation. In addition, this can also prevent the locking member from accidentally falling off the female head. At the same time, when the locking member is in the first position, since the engaging platform of the locking member is located between the inner diameter and the outer diameter of the through hole of the female head, it can ensure that the male head can be smoothly inserted into the through hole of the female head.

[0038] In an alternative embodiment, a groove is provided on a side of the connecting arm away from the jack, and the groove is configured to abut against the female head when the male head is inserted into the jack.

[0039] By providing the groove, when the male head and the female head are assembled, the groove abuts against a partial outer peripheral side of the female head, thereby increasing the contact area between the locking member and the female head and ensuring the stability of the connection between the locking member and the female head.

[0040] In an alternative embodiment, a second catch and a third catch are further provided at an end of the connecting arm away from the engaging platform, and a second card slot is formed between the second catch and the third catch;

[0041] The female head is further provided with a protrusion;

[0042] In the second position, the protrusion is inserted into the second card slot.

[0043] By providing a protrusion on the female head and correspondingly providing a second card slot on the locking member, when the locking member moves to the second position, that is, when the female head and the male head are assembled in place, the protrusion is exactly inserted into the second card slot at this time, thereby preventing the movement of the locking member to prompt the user that the female head and the male head are already assembled in place. The structure is simple and the operation is convenient.

[0044] In an alternative embodiment, the first catch is located on a side of the connecting arm away from the jack;

[0045] The second catch and the third catch are located on a side of the connecting arm close to the jack.

[0046] When the first catch is provided on the side of the connecting arm away from the jack, the first card slot can be correspondingly provided on the outer peripheral side of the female head to achieve the engagement between the first catch and the first card slot when the locking member is in the first position. At this time, the groove and the first catch are on the same side of the connecting arm. When the second catch and the third catch are located on the side of the connecting arm close to the jack and the second card slot is also on the side of the connecting arm close to the jack, the protrusion can be correspondingly provided outside the edge of the through hole of the female head to achieve the engagement between the second card slot and the protrusion when the locking member is in the second position.

[0047] In an alternative embodiment, a plurality of connecting arms are provided, the plurality of connecting arms are arranged at intervals, and the first hook, the second hook and the third hook are arranged on each connecting arm;

[0048] A plurality of first card slots are provided, and the plurality of first card slots are arranged at intervals on the female head;

[0049] A plurality of protrusions are provided, and the plurality of protrusions are arranged at intervals on the female head;

[0050] Each connecting arm is arranged corresponding to one first card slot and one protrusion.

[0051] By providing multiple groups of mutually cooperating first card slots and first hooks, multiple groups of mutually cooperating second card slots and protrusions, and arranging each group of first card slots and first hooks at intervals, and arranging each group of second card slots and protrusions at intervals, the connection stability between the female head and the locking member can be ensured.

[0052] In an alternative embodiment, a limiting groove is provided on one side of the locking member facing the jack, and a limiting block is further provided on the female head;

[0053] In the second position, the limiting block is inserted into the limiting groove.

[0054] By providing a limiting block outside the edge of the through hole of the female head and correspondingly providing a limiting groove on the locking member, when the locking member moves to the second position, that is, when the female head and the male head are assembled in place, at this time the limiting block is just inserted into the limiting groove, thereby preventing the movement of the locking member to prompt the user that the female head and the male head have been assembled in place, with a simple structure and convenient operation.

[0055] In an alternative embodiment, a plurality of limiting grooves are provided, and the plurality of limiting grooves are arranged at intervals on the locking member;

[0056] A plurality of limiting blocks are provided, and the plurality of limiting blocks are arranged at intervals on the female head;

[0057] The plurality of limiting grooves and the plurality of limiting blocks are arranged in one-to-one correspondence.

[0058] By providing multiple groups of mutually cooperating limiting grooves and limiting blocks, and arranging each group of limiting grooves and limiting blocks at intervals, the connection stability between the female head and the locking member can be further ensured.

[0059] In an alternative embodiment, the first direction is perpendicular to the second direction.

[0060] The second direction is configured to be perpendicular to the first direction so that the locking member can limit the identification member when in the first position.

[0091] The embodiments of the technical solutions of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present application more clearly, so they are only examples and cannot be used to limit the protection scope of the present application.

[0092] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the description of the specification, claims and drawings of this application are intended to cover non-exclusive inclusion.

[0093] In the description of the embodiments of the present application, technical terms such as "first" and "second" are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order or primary-secondary relationship of the indicated technical features. In the description of the embodiments of the present application, "a plurality" means more than two, unless otherwise specifically defined.

[0094] Referring to "embodiments" herein means that specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0095] In the description of the embodiments of the present application, the term "a plurality" refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0096] At present, from the perspective of the development of the market situation, the application of power battery devices is becoming more and more extensive. Power battery devices are not only used in energy storage power systems such as hydraulic, thermal, wind, and solar power stations, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in many fields such as aerospace. With the continuous expansion of the application fields of power battery devices, the market demand is also constantly increasing.

[0097] The thermal management system of a power battery device is a system composed of components used to regulate the temperature of battery cells in the battery device, which can heat or cool the battery cells. The thermal management system generally includes a heat exchange plate and a pipeline connected to the heat exchange plate. The pipeline is communicated with the flow channel in the heat exchange plate to circulate the heat exchange medium.

[0098] The pipelines of the existing thermal management systems usually need to be connected through a connection structure. Before the connection structure is used for the pipeline, the female head and the male head of the connection structure need to be assembled together first, and they need to be assembled in place before they can be put into use. The inventor found that when assembling the male head and the female head to form a connection structure, users usually rely on visual observation or the sound generated by the collision of the male head and the female head during assembly to confirm whether the male head and the female head are assembled in place. The error rate of this judgment method is extremely high, resulting in frequent situations where the male head and the female head are not assembled in place. When the situation where the male head and the female head are not assembled in place occurs, it is not easy for users to find, so that the unassembled connection structure cannot function when installed in the pipeline of the battery device, thereby affecting the service life of the battery device.

[0099] Based on the above considerations, in order to solve the problem of frequent occurrences of the situation where the male head and the female head are not assembled in place, and the problem that it is not easy for users to detect when the male head and the female head are not assembled in place, the inventor has conducted in-depth research and designed a connection structure, including: a male head, a female head, an identification member, and a locking member. There is a through hole on the female head, and the through hole is used for the male head to be inserted to achieve assembly with the female head. Before the male head is inserted into the through hole of the female head, both the identification member and the locking member are pre-installed on the female head. Specifically, the locking member and the identification member are located on the same side of the female head. The second insertion portion of the identification member is inserted and matched with the first insertion portion of the female head along the second direction. The locking member passes through the identification member and is movably connected to the female head. At this time, the position where the locking member is located is the first position, and the locking member can limit the identification member along the second direction. When the male head and the female head are assembled, that is, the male head is inserted into the through hole of the female head. After the depth of the insertion hole of the male head reaches a preset value, the locking member moves along the first direction from the first position towards the direction close to the central axis of the female head. When it can no longer move, the locking member moves to the second position. At this time, the locking member is locked with the female head, and at the same time, the male head is also locked in the through hole of the female head. During the process of the locking member moving from the first position towards the direction close to the central axis of the female head, the locking member will gradually move away from the identification member. After the locking member moves to the second position, it can release the limit on the identification member in the second direction, enabling the identification member to slide along the second direction and disengage from the female head. The technical solution of the embodiment of the present application, by setting the identification member and the locking member, when the male head and the female head are assembled in place, the identification member can slide along the second direction and disengage from the female head, and the locking member can no longer move relative to the female head. By observing these two objective phenomena, the user can confirm that the male head and the female head have been assembled in place, thereby avoiding the occurrence of the situation where the male head and the female head are not assembled in place and improving the assembly accuracy rate.

[0100] The connection structure and the battery device disclosed in the embodiments of the present application can be but are not limited to being used in electrical equipment such as vehicles, ships, or aircraft. The power supply system of the electrical equipment can be composed of the connection structure, the battery device, etc. disclosed in the present application. In this way, the situation where the male head and the female head of the connection structure in the thermal management system of the battery device are not assembled in place can be avoided, the assembly accuracy rate can be improved, and the normal use of the pipeline of the thermal management system of the battery device can be ensured.

[0101] The technical solutions described in the embodiments of the present application are applicable to various electrical equipment using battery devices, such as mobile phones, tablets, laptop computers, electric toys, power tools, battery cars, electric vehicles, ships, spacecraft, and so on. Among them, electric toys can include fixed or mobile electric toys, such as game consoles, electric vehicle toys, electric ship toys, and electric aircraft toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spaceships, etc.

Refer to Figure 4 、 Figures 11 to 13 , in the first position, the locking member 3 can limit the identification member 4 along the second direction y, making it difficult for the identification member 4 to move relative to the female head 2 along the second direction y. Refer to Figure 14 and Figure 15 , in the second position, the locking member 3 can lock the male head 1 and release the limit of the identification member 4 in the second direction y, enabling the identification member 4 to move relative to the female head 2 along the second direction y.

[0109] The second direction y is parallel to the insertion direction of the male head 1.

[0110] In the technical solution of the embodiment of the present application, before the male head 1 is inserted into the through hole of the female head 2, the identification member 4 and the locking member 3 are both pre-installed on the female head 2. Specifically, the locking member 3 and the identification member 4 are located on the same side of the female head 2. The identification member 4 can surround a partial outer peripheral side of the female head 2, and the locking member 3 also surrounds a partial outer peripheral side of the female head 2. The second insertion portion 41 of the identification member 4 is inserted and matched with the first insertion portion 201 of the female head 2 along the second direction y. The locking member 3 passes through the identification member 4 and is movably connected to the female head 2. At this time, the position where the locking member 3 is located is the first position, and the locking member 3 can limit the identification member 4 along the second direction y. When the male head 1 is assembled with the female head 2, that is, the male head 1 is inserted into the through hole of the female head 2. After the depth of the insertion jack 202 of the male head 1 reaches a preset value, the locking member 3 moves along the first direction x from the first position towards the direction close to the central axis of the female head 2. When it cannot move any further, the locking member 3 moves to the second position. At this time, the locking member 3 is locked with the female head 2, and at the same time, the male head 1 is also locked in the through hole of the female head 2. During the process of the locking member 3 moving from the first position towards the direction close to the central axis of the female head 2, the locking member 3 will gradually move away from the identification member 4. After the locking member 3 moves to the second position, it can release the limit of the second direction y on the identification member 4, so that the identification member 4 can slide along the second direction y and disengage from the female head 2. Compared with the way that the identification member is clamped to the locking member and can be disengaged along the first direction under the action of the locking member, in the present application, the identification member 4 slides relative to the female head 2 along the second direction y to disengage, canceling the clamping between the identification member 4 and the locking member 3, which can reduce the processing difficulty of the workpiece and avoid the phenomenon that the identification member 4 is difficult to disengage due to clamping. The technical solution of the embodiment of the present application sets the identification member 4 and the locking member 3. When the male head 1 and the female head 2 are assembled in place, the identification member 4 can slide along the second direction y and disengage from the female head 2, and the locking member 3 can no longer move relative to the female head 2. By observing these two objective phenomena, the user can confirm that the male head 1 and the female head 2 have been assembled in place, thereby avoiding the situation where the male head 1 and the female head 2 are not assembled in place and improving the assembly accuracy.

[0111] According to some embodiments of the present application, referring to Figures 2 - 4 , the first direction x is perpendicular to the second direction y.

[0112] The second direction y is configured to be perpendicular to the first direction x so that the locking member 3 can limit the identification member 4 when in the first position.

[0113] According to some embodiments of the present application, referring to Figure 5 and Figure 9 , the first insertion portion 201 includes a slot 2011, and one end of the slot 2011 along the second direction y has an opening. The second insertion portion 41 includes a plug-in block 411, and the plug-in block 411 can be inserted into or disengaged from the slot 2011 through the opening.

[0114] Taking Figure 2 the direction shown as an example, the opening is located at the upper end of the slot 2011 along the second direction y. In embodiments not shown in other figures, the opening may also be located at the lower end of the slot along the second direction, as long as the plugging block can be inserted into or detached from the slot through the opening.

[0115] Configure the first engaging portion 201 as the slot 2011 and the second engaging portion 41 as the plugging block 411. When the identification member 4 is pre-installed on the female head 2, the plugging block 411 can be inserted into the slot 2011 through the opening of the slot 2011. When the locking member 3 moves to the second position, the plugging block 411 can be detached from the slot 2011 through the opening of the slot 2011. Through the adaptation of the plugging block 411 and the slot 2011, the locking member 3 and the female head 2 are connected in a plugging manner, and the structure is simple.

[0116] In embodiments not shown in other figures, the first engaging portion may also be configured as the plugging block and the second engaging portion may be configured as the slot, as long as the first engaging portion and the second engaging portion can be cooperatively plugged along the second direction.

[0117] According to some embodiments of the present application, referring to Figures 2 - 4 , Figure 12 , a plurality of slots 2011 are provided, and the plurality of slots 2011 are spaced apart on the outer periphery of the female head 2. A plurality of plugging blocks 411 are provided, and the plurality of plugging blocks 411 are provided in one-to-one correspondence with the plurality of slots 2011.

[0118] Specifically, taking Figures 2 - 10 the shown embodiment as an example, two slots 2011 are provided, and the two slots 2011 are spaced apart on the outer periphery of the female head 2. Two plugging blocks 411 are provided, and the two plugging blocks 411 are provided in one-to-one correspondence with the two slots 2011.

[0119] By providing multiple groups of slots 2011 and plugging blocks 411 that are cooperatively plugged with each other, and the groups of slots 2011 and plugging blocks 411 are spaced apart, the stability of the connection between the identification member 4 and the female head 2 is ensured.

[0120] According to some embodiments of the present application, referring to Figures 2 - 4 , the female head 2 includes a first main body 21 and a second main body 22. The second main body 22 is sleeved on one end of the first main body 21, and the first engaging portion 201 and the jack 202 are both provided on the second main body 22.

[0121] When assembling the female head 2, by sleeving the second main body 22 on one end of the first main body 21 and providing the first engaging portion 201 and the jack 202 on the second main body 22, the female head 2 is formed, and the first engaging portion 201 and the jack 202 on the female head 2 are provided.

[0122] According to some embodiments of the present application, with reference to Figures 2 - 4 , Figure 12 , one end of the first body 21 is provided with a first engaging portion 211, the second body 22 is further provided with a second engaging portion 221, and the first engaging portion 211 engages with the second engaging portion 221.

[0123] One of the first engaging portion 211 and the second engaging portion 221 is a buckle, and the other is a socket.

[0124] Through the snap - fit cooperation between the first engaging portion 211 and the second engaging portion 221, the connection between one end of the first body 21 and the second body 22 is realized. In addition, by configuring one of the first engaging portion 211 and the second engaging portion 221 as a buckle and the other as a socket, the engagement between the first engaging portion 211 and the second engaging portion 221 is realized.

[0125] According to some embodiments of the present application, with reference to Figures 4 - 6 , Figure 5 is a schematic structural diagram of the second body 22 provided by an embodiment of the present application; Figure 6 is a schematic structural diagram of the second body 22 from another angle provided by an embodiment of the present application. The second body 22 includes an outer cylinder 222, an inner cylinder 223, a connecting portion 224, and a sealing member 225. The inner cylinder 223 is disposed inside the outer cylinder 222, the connecting portion 224 is connected between the outer cylinder 222 and the inner cylinder 223, the first inserting portion 201 is disposed on the outer cylinder 222, and the inserting hole 202 is disposed on the inner cylinder 223.

[0126] The end face of the first body 21 abuts against the connecting portion 224.

[0127] The sealing member 225 is disposed on the inner cylinder 223, and the sealing member 225 is used to seal the gap between the male head 1 and the first body 21 when the male head 1 is inserted into the inserting hole 202.

[0128] The inner cylinder 223, the connecting portion 224, and the outer cylinder 222 are connected in sequence from the inside to the outside. By providing the first inserting portion 201 on the outer cylinder 222, the insertion connection between the second body 22 and the identification member 4 is realized. By providing the inserting hole 202 on the inner cylinder 223, the connection between the second body 22 and the male head 1 is realized. In addition, by providing the sealing member 225 on the inner cylinder 223 to seal the gap between the male head 1 and the first body 21, the sealing performance between the male head 1 and the female head 2 is ensured.

[0129] According to some embodiments of the present application, with reference to Figures 9 - 10 , Figure 9 is a schematic structural diagram of the identification member 4 provided by an embodiment of the present application; Figure 10 is a schematic structural diagram of the identification member 4 from another angle provided by an embodiment of the present application. The identification member 4 is further provided with a through - hole 42 through which the locking member 3 can pass.

[0130] Referring to Figure 11 and Figure 13 , at the first position, part of the locking member 3 is located within the through hole 42 so as to be able to limit the identification member 4 in the second direction y.

[0131] Referring to Figure 14 and Figure 15 , at the second position, the locking member 3 is away from the through hole 42 to release the limit on the identification member 4 in the second direction y.

[0132] By providing the through hole 42, the locking member 3 can pass through the identification member 4 from the through hole 42, and then surround the local outer peripheral side of the female head 2 and be connected to the female head 2.

[0133] According to some embodiments of the present application, referring to Figures 7 - 8 , the identification member 4 is further provided with a pulling portion 43, and the pulling portion 43 is used for a user to remove the identification member 4 from the female head 2.

[0134] By providing the pulling portion 43, when the male head 1 and the female head 2 are assembled, it is convenient for the user to remove the identification member 4 from the female head 2 through the pulling portion 43, providing a force application point for the user to remove the identification member 4 and facilitating the user's operation.

[0135] According to some embodiments of the present application, referring to Figure 3 , and further referring to Figure 7 and Figure 8 , Figure 7 is a schematic structural diagram of the locking member 3 provided by the embodiment of the present application; Figure 8 is a schematic structural diagram of the locking member 3 from another angle provided by the embodiment of the present application. An annular groove 11 is provided on the outer peripheral surface of the male head 1. The locking member 3 includes a clamping platform 31.

[0136] Referring to Figure 15 , at the second position, the clamping platform 31 is inserted into the annular groove 11.

[0137] When the depth of insertion of the male head 1 into the jack 202 reaches a preset value, the annular groove 11 and the clamping platform 31 of the locking member 3 will be in the same plane. The locking member 3 can be moved from the first position to the second position by the insertion of the clamping platform 31 into the annular groove 11, so that the inner diameter of the clamping platform 31 of the locking member 3 abuts against the outer diameter of the annular groove 11 of the male head 1. Since the inner diameter of the clamping platform 31 is not greater than the outer diameter of the annular groove 11 of the male head 1, when the clamping platform 31 is inserted into the annular groove 11, the male head 1 will not continue to move along the through hole of the female head 2. At this time, the locking member 3 is locked with the male head 1, and at the same time, the locking member 3 is also locked with the female head 2 to lock the male head 1 and the female head 2, thereby completing the assembly of the male head 1 and the female head 2.

[0138] According to some embodiments of the present application, referring to Figures 7 - 8 , the locking member 3 further includes a connecting arm 32 connected to the clamping platform 31, and a first hook 33 is provided at one end of the connecting arm 32 away from the clamping platform 31. The female head 2 is also provided with a first slot 23.

[0140] By providing the first slot 23 on the female head 2 and correspondingly providing the first hook 33 on the locking member 3, when the first hook 33 of the locking member 3 is engaged with the first slot 23 of the female head 2, the locking member 3 is just in the first position at this time, thus playing a role in positioning the locking member 3, enabling the locking member 3 to quickly be in the first position during installation. In addition, this can also prevent the locking member 3 from accidentally falling off the female head 2. At the same time, when the locking member 3 is in the first position, since the clamping platform 31 of the locking member 3 is located between the inner diameter of the through hole of the female head 2 and the outer diameter of the female head 2, it can ensure that the male head 1 can be smoothly inserted into the through hole of the female head 2.

[0141] According to some embodiments of the present application, referring to Figures 7 - 8 , a groove 34 is provided on one side of the connecting arm 32 away from the jack 202, and the groove 34 is used to abut against the female head 2 when the male head 1 is inserted into the jack 202.

[0142] By providing the groove 34, when the male head 1 and the female head 2 are assembled, the groove 34 abuts against the partial outer peripheral side of the female head 2, thereby increasing the contact area between the locking member 3 and the female head 2 and ensuring the stability of the connection between the locking member 3 and the female head 2.

[0143] According to some embodiments of the present application, referring to Figures 5 - 8 , a second hook 35 and a third hook 36 are further provided at one end of the connecting arm 32 away from the clamping platform 31, and a second slot 37 is formed between the second hook 35 and the third hook 36.

[0145] Referring to Figure 14 , in the second position, the protrusion 24 is inserted into the second slot 37.

[0146] By providing the protrusion 24 on the female head 2 and correspondingly providing the second slot 37 on the locking member 3, when the locking member 3 moves to the second position, that is, when the female head 2 and the male head 1 are assembled in place, the protrusion 24 is just inserted into the second slot 37 at this time, thereby preventing the movement of the locking member 3 to prompt the user that the female head 2 and the male head 1 are already assembled in place, with a simple structure and convenient operation.

[0147] According to some embodiments of the present application, with reference to Figure 7 , Figure 8 , Figure 11 , the first catch 33 is located on the side of the connecting arm 32 away from the jack 202.

[0148] The second catch 35 and the third catch 36 are located on the side of the connecting arm 32 close to the jack 202.

[0149] When the first catch 33 is provided on the side of the connecting arm 32 away from the jack 202, the first slot 23 can be correspondingly provided on the outer peripheral side of the female head 2, so as to realize the snap-fit between the first catch 33 and the first slot 23 when the locking member 3 is in the first position. At this time, the groove 34 and the first catch 33 are on the same side of the connecting arm 32. When the second catch 35 and the third catch 36 are located on the side of the connecting arm 32 close to the jack 202, and the second slot 37 is also on the side of the connecting arm 32 close to the jack 202, the protrusion 24 can be correspondingly provided outside the edge of the through hole of the female head 2, so as to realize the snap-fit between the second slot 37 and the protrusion 24 when the locking member 3 is in the second position.

[0150] According to some embodiments of the present application, with reference to Figures 7 - 8 , Figure 11 , a plurality of connecting arms 32 are provided, and the plurality of connecting arms 32 are spaced apart. Each connecting arm 32 is provided with a first catch 33, a second catch 35 and a third catch 36.

[0153] Each connecting arm 32 is provided corresponding to a first slot 23 and a protrusion 24.

[0154] By providing multiple sets of mutually cooperating and snap-fitting first slots 23 and first catches 33, multiple sets of mutually cooperating and snap-fitting second slots 37 and protrusions 24, and spacing each set of first slots 23 and first catches 33 apart, and spacing each set of second slots 37 and protrusions 24 apart, the connection stability between the female head 2 and the locking member 3 can be ensured.

[0155] According to some embodiments of the present application, with reference to Figure 11 and Figure 14 , a limiting groove 38 is provided on the side of the locking member 3 facing the jack 202, and the female head 2 is further provided with a limiting block 25. Specifically, the limiting block 25 can be provided on the second body 22.

[0156] With reference to Figure 14, at the second position, the limiting block 25 is inserted into the limiting groove 38.

[0157] By arranging the limiting block 25 outside the edge of the through hole of the female head 2 and correspondingly arranging the limiting groove 38 on the locking member 3, when the locking member 3 moves to the second position, that is, when the female head 2 and the male head 1 are assembled in place, at this time the limiting block 25 is just inserted into the limiting groove 38, thereby preventing the movement of the locking member 3 to prompt the user that the female head 2 and the male head 1 have been assembled in place. The structure is simple and the operation is convenient.

[0158] According to some embodiments of the present application, referring to Figure 11 and Figure 14 , a plurality of limiting grooves 38 are provided, and the plurality of limiting grooves 38 are arranged at intervals on the locking member 3.

[0159] A plurality of limiting blocks 25 are provided, and the plurality of limiting blocks 25 are arranged at intervals on the female head 2.

[0160] The plurality of limiting grooves 38 and the plurality of limiting blocks 25 are arranged in one-to-one correspondence.

[0161] By providing multiple groups of mutually cooperating and inserted limiting grooves 38 and limiting blocks 25, and the groups of limiting grooves 38 and limiting blocks 25 are arranged at intervals, the connection stability between the female head 2 and the locking member 3 can be further ensured.

[0162] According to some embodiments of the present application, an electronic tag is provided inside the identification member 4. The electronic tag can be provided with a two-dimensional code or a bar code. The electronic tag contains information of the female head 2, such as the number of the female head 2, etc. After the identification member 4 is removed from the female head 2, the electronic tag can be scanned by a barcode scanner. After the information of the female head 2 is entered into the system, it can be considered that the male head 1 and the female head 2 have been installed in place. When this assembly process includes the assembly of multiple male heads 1 and female heads 2, the scanning system needs to count. The repeated two-dimensional codes are invalid codes and will not be counted. When the counted quantity is consistent with the specified assembly quantity of this process, it will be prompted that this process has been completed in full, and the material can enter the next process.
