Description

Technical Field

[0001] The utility model relates to the technical field of liquid-cooled energy storage systems, in particular to a connector connected to an energy storage liquid cooling device and an energy storage liquid cooling device. Background Art

[0002] In the energy storage market, liquid-cooled energy storage system products are the main ones. Liquid-cooled energy storage system refers to an energy storage system that uses liquid cooling technology. It absorbs and transfers heat through a liquid medium (usually water or a specific coolant), thereby controlling the temperature of the energy storage unit (such as a battery). In energy storage systems, especially large-scale battery energy storage systems (such as grid-scale applications, electric vehicles, etc.), energy storage liquid cooling devices are very important components because they can help maintain the battery within the optimal operating temperature range and improve the performance and life of the battery. In addition, the connectors connected to the energy storage liquid cooling device are also important components. For example, the male connector is generally on the battery pack and the female connector is on the liquid cooling pipe. The connection between the male and female connectors is realized to achieve the connection between the liquid-cooled battery pack and the liquid cooling pipe, thereby transporting the liquid medium to achieve the purpose of cooling, thereby realizing the temperature control of the energy storage liquid-cooled battery pack.

[0003] Since brass has good strength and hardness, and good corrosion resistance. Therefore, brass is often chosen as the material of the male and female connectors connected to the energy storage liquid cooling device. In the prior art, the connectors connected to the energy storage liquid cooling device are mostly plug-in type, wherein the male and female connectors are mostly connected by threads, for example, the male head contains an external thread, and the female head contains an internal thread. The male head with an external thread must be rotated a certain number of times before reaching a predetermined torque to ensure a tight fit with the female head with an internal thread. This also causes the male head to include a certain operating distance in order to perform the above-mentioned rotation process to be tightly connected with the female head, thereby achieving a sealing effect. However, since the material of both the male and female heads is brass, reserving a certain operating distance is bound to lead to excessively high production costs. Based on this, how to reduce the production cost of connectors connected to the energy storage liquid cooling device has become a technical problem that needs to be solved urgently.

On the contrary, the purpose of introducing the utility model in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide an in-depth understanding of the present invention, the following description will contain many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0033] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0034] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0036] The present invention provides the following technical solutions to solve the problem of high cost of “connectors connected to energy storage liquid cooling devices” (hereinafter referred to as “connectors”) in the prior art.

[0037] A connector connected to an energy storage liquid cooling device, comprising:

[0038] The female connector includes a first half-cylinder and a positioning block, wherein the first half-cylinder is formed by cutting a portion of a cylinder along the axial direction, and the positioning block is located on the outer peripheral wall of the first half-cylinder;

[0039] The male connector is used to connect with the female connector, and includes a second half-cylinder and a locking ring. The second half-cylinder is formed by cutting a portion of the cylinder along the axial direction and cooperates with the first half-cylinder. The locking ring is sleeved on the outer circumference of the second half-cylinder.

[0040] Sealing ring: located at the joint between the male and female connectors;

[0041] When the male head and the female head are docked, the male head and the female head form a whole tube, the male head and the female head are sealed and connected by the sealing ring, and the positioning block and the locking ring are connected by a buckle to lock the whole tube.

[0042] The male and female heads of the connector provided by the present invention are connected by snap-fitting, not by threading. Therefore, there is no need to reserve a certain operating distance for either the male or female head, which reduces the production cost of the connector. Furthermore, the present invention optimizes the structure of the male and female heads. The connectors of the female and male heads are designed to be half-cylinder structures, that is, the female head at the connector is designed to be a first half-cylinder structure, and the male head at the connector is designed to be a second half-cylinder structure. When the male and female heads are docked, the first half-cylinder and the second half-cylinder are docked, and the male and female heads form a whole cylinder. The whole cylinder is then locked by snap-fitting a locking ring sleeved on the outer periphery of the second half-cylinder with a positioning block on the outer peripheral wall of the first half-cylinder, thereby ensuring a sealing effect while further reducing the production cost of the connector. In addition, the connector provided by the present invention is easy to assemble and reduces assembly time.

[0043] The above technical solution will be described in detail below with reference to the accompanying drawings.

[0044] like Figure 1-3 As shown, the connector provided by the present invention includes a female connector 2, wherein the female connector 2 includes a first half-cylinder 3 and a positioning block 4, the positioning block 4 is located on the outer peripheral wall of the first half-cylinder 3, and the first half-cylinder 3 is formed by cutting a portion of the cylinder along the axial direction, that is, the first half-cylinder 3 is formed by cutting a portion of the cylinder along the axial direction. The axial direction in the present invention refers to the axial direction of the connector 1, for example Figure 3 、 Figure 4-Figure 5 、 Figure 7-Figure 8 The X direction in .

[0045] like Figure 4-5 As shown, the connector provided by the present invention also includes a male connector 5, which is used to mate with the female connector 2. The male connector 5 includes a second half-barrel 6 and a locking ring 7. The second half-barrel 6 is formed by cutting a portion of a cylinder along the axial direction. Specifically, the second half-barrel 6 is formed by cutting a portion of the cylinder along the axial direction. The axial direction refers to the axial direction of the connector 1. The second half-barrel 6 is used to mate with the first half-barrel 3, and the locking ring 7 is sleeved onto the outer circumference of the second half-barrel 6.

[0046] like Figure 6-Figure 9As shown, the connector 1 provided by the present invention further includes a sealing ring 8, which is provided at the joint between the male connector 5 and the female connector 2. The sealing ring 8 can be provided at the corresponding joint of the female connector 2 for jointing with the male connector 5, or at the corresponding joint of the male connector 5 for jointing with the female connector 2. Specifically, as Figure 3 and Figure 6 As shown, the female connector 2 is provided with a slot 11 at its interface. A sealing ring 8 can be glued into the slot 11 of the female connector 2. The two semi-circular ring-shaped portions of the sealing ring 8 are glued into first slots 11.1 provided in the two semi-circular ring-shaped portions of the first half-barrel 3. Simultaneously, the two parallel semi-circular rings of the sealing ring 8 are glued into second slots 11.2 provided in the first half-barrel 3. When the male connector 5 and the female connector 2 are docked, the male connector 5 and the female connector 2 form a complete barrel. The male connector 5 and the female connector 2 are sealed together by the sealing ring 8. The positioning block 4 and the locking ring 7 are connected by a snap-fit connection to lock the entire barrel, thereby ensuring a sealed seal. Specifically, the sealing ring is made of silicone.

[0047] Furthermore, if Figure 1-Figure 3 As shown, the positioning block 4 has a first side surface 4.1 and a second side surface 4.2 arranged opposite to each other along the circumference of the first half cylinder 3, wherein the circumference is the circumferential direction, for example Figure 8 The Z direction in .

[0048] like Figure 4-Figure 5 、 Figure 9 As shown, the locking ring 7 has two disconnected ends: a first hook 7.1 and a second hook 7.2. When the positioning block 4 is snap-fitted to the locking ring 7, the first hook 7.1 snaps onto the first side surface 4.1, and the second hook 7.2 snaps onto the second side surface 4.2. These first and second hooks 7.1, 7.2 lock the entire cylinder, ensuring uniform and reliable force (the tightening force after the snap fastening). This snap-fit connection is easy to operate, ensuring a good seal while also reducing assembly time.

[0049] Furthermore, if Figure 2 and Figure 9 As shown, positioning block 4 has a top surface 4.3, with chamfers 4.4 defined between top surface 4.3 and first side surface 4.1, and between top surface 4.3 and second side surface 4.2. Chamfers eliminate sharp edges and corners, reducing the risk of scratches and cuts during assembly. Chamfers also reduce stress concentration, improving the structural strength of the connector and extending its service life.

[0050] Furthermore, if Figure 1-Figure 3As shown, the first half-cylinder 3 includes a first cylindrical portion 3.1 and a first half-cylinder portion 3.2. The first cylindrical portion 3.1 and the first half-cylinder portion 3.2 are butted end-to-end and integrally formed. The first half-cylinder portion 3.2 forms a first arcuate groove 3.2.1. Specifically, the first half-cylinder portion 3.2, such as the first arcuate groove 3.2.1, is obtained by axially sectioning the cylinder.

[0051] Furthermore, if Figure 4-Figure 5 As shown, the second half-barrel 6 comprises a second cylindrical portion 6.1 and a second half-barrel portion 6.2. The second cylindrical portion 6.1 and the second half-barrel portion 6.2 are butted together at their ends and are integrally formed. The second half-barrel portion 6.2 forms a second arcuate groove 6.2.1. When the male connector 5 and the female connector 2 are butted together, the male connector 5 and the female connector 2 cooperate to form a complete barrel through the first arcuate groove 3.2.1 and the second arcuate groove 6.2.1. Specifically, the barrel is cut along the axial direction to obtain the second half-barrel portion 6.2 with an arcuate cross-section, such as the second arcuate groove 6.2.1.

[0052] Furthermore, if Figure 4-Figure 5 As shown, the male connector 5 in each of the above embodiments further includes an elastic pad 9, which is disposed between the outer periphery of the second half-barrel 6 and the locking ring 7. Specifically, the elastic pad 9 is glued between the outer periphery of the second half-barrel 6 and the locking ring 7. The elastic pad 9 can buffer the compressive force between the outer periphery of the second half-barrel 6 and the locking ring 7, thereby relieving pressure. Therefore, the elastic pad can act as a buffer. In particular, the elastic pad is made of rubber.

[0053] Furthermore, if Figure 4-5 and Figure 7-8 As shown, there are multiple locking rings 7, and the multiple locking rings 7 are distributed along the axial direction X, and the spacing d between the adjacent locking rings 7 along the axial direction X is 5mm-10mm. Studies have found that when multiple locking rings are set, and the spacing d between the adjacent locking rings 7 along the axial direction X is set to 5mm-10mm, the sealing effect can be further improved, and the stable connection effect between the male head 5 and the female head 2 can be further strengthened. Furthermore, when facing different working environments, such as facing energy storage liquid cooling devices of different sizes, it is necessary to design connectors 1 of different sizes to match them, so as to achieve a sealing effect. The operator can set a corresponding number of locking rings 7 on the male head 5 according to the size of the connector 1, within the above-mentioned spacing range, to achieve a better sealing effect, and at the same time, to strengthen the stability of the connection between the male head 5 and the female head 2.

[0054] Furthermore, if Figure 7-Figure 9As shown, the number of positioning blocks 4 is the same as the number of locking rings 7. The positioning blocks 4 are distributed along the axial direction. When the male connector 5 and the female connector 2 are connected, the multiple positioning blocks 4 are connected to the multiple locking rings 7 through snap fastening to lock the entire barrel. By providing multiple positioning blocks 4 and multiple locking rings 7, the sealing effect can be further improved.

[0055] Furthermore, if Figure 1-Figure 2 As shown, the female connector 2 further includes a stopper 10, which abuts against one axial end of the positioning block 4 and is used to limit the axial movement of the locking ring 7 when the positioning block 4 is connected to the locking ring 7 via a snap-fit connection. This further improves the stability of the connection between the female connector 2 and the male connector 5.

[0056] Furthermore, in the above embodiments, the locking ring 7, the positioning block 4 and the limiting block 10 are all made of stainless steel.

[0057] The present invention also provides an energy storage liquid cooling device, including the connectors described in each of the above embodiments. The male connector is generally located on the battery pack, and the female connector is located on the liquid cooling pipe. The male and female connectors are connected to each other to achieve a connection between the liquid-cooled battery pack and the liquid cooling pipe, thereby enabling temperature control of the energy storage liquid-cooled battery pack.

[0058] Since the connecting piece provided by the present invention has lower cost, the cost of the energy storage liquid cooling device provided by the present invention is also lower.

[0059] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above description is provided to further illustrate the present invention in conjunction with specific embodiments, and that the present invention should not be construed as being limited to these descriptions. Those skilled in the art may make various changes in form and detail, including simple deductions or substitutions, without departing from the spirit and scope of the present invention.
