[0001] The present application relates to the field of battery technology, and in particular to a wire outlet holder and a battery pack. Background Art
[0002] The battery system is an important unit for energy storage and supply. The battery system is composed of many parts. The battery pack is the core power supply module of the battery system, which is equivalent to the heart of the battery system. The battery pack usually includes multiple single cells connected in series. Of course, it can also include single cells connected in parallel. Therefore, the voltage of the battery pack is usually higher. The copper busbar is the part that connects the battery pack to the outside world. The copper busbar is also called copper busbar or copper busbar. Its surface is usually attached with an insulating layer. It can play the role of transmitting current and can realize the conductive connection between battery packs or between battery packs and other components. In actual use, the copper busbar is generally connected to the battery pack using a wire outlet seat. Specifically, it needs to be connected to the battery pack through the clamping structure provided on the wire outlet seat. The wire outlet seat includes a seat body and a protective cover connected to the seat body. The seat body is provided with an insert. The insert can be used to fix the copper busbar. The protective cover protects the insert to prevent staff from accidentally touching it.
[0003] Since there is a clearance fit between the rotating axis of the battery pack outlet seat protective cover and the axial hole of the outlet seat, there is no resistance force during the rotation process after the protective cover is opened, and it is easily rotated back to its original position under the action of gravity, so the operator needs to rotate the protective cover again to open it when fixing the bolts, affecting production efficiency. Summary of the Invention
[0004] The embodiments of the present application provide a wire outlet holder and a battery pack to solve the problem in the related art that there is no blocking force between the rotating shaft of the protective cover and the axial hole of the wire outlet holder. After the protective cover is opened, it is easily rotated back to its original position due to the action of gravity, so that the operator needs to rotate the protective cover again to open it when fixing the bolts, which affects production efficiency.
[0005] In a first aspect, a wire outlet seat is provided, comprising:
[0006] A seat body, wherein the seat body is provided with one of an axial hole and a rotating shaft;
[0007] A protective cover, wherein the protective cover is provided with the other of an axial hole and a rotating shaft, and the rotating shaft is rotatably connected to the axial hole;
[0008] A rotation blocking structure, the rotation blocking structure comprising a protrusion and a groove for accommodating at least a portion of the protrusion, the protrusion being located on one of the axial hole and the rotating shaft, the groove being located on the other of the axial hole and the rotating shaft, and the thickness of the protrusion being greater than the gap between the inner wall of the axial hole and the outer wall of the rotating shaft when the protrusion is located in the groove.
[0009] In some embodiments, the shaft hole is provided on the base, and the rotating shaft is provided on the protective cover.
[0010] In some embodiments, the protrusion is located on the rotating shaft, and the groove is located on the shaft hole.
[0011] In some embodiments, along the circumferential direction of the shaft hole or the rotating shaft, on at least a portion of the wall surface of the shaft hole or the rotating shaft, a plurality of the protrusions are evenly distributed;
[0012] Along the circumferential direction of the shaft hole or the rotating shaft, a plurality of the grooves are evenly distributed on at least a portion of the wall surface of the shaft hole or the rotating shaft;
[0013] The interval between two adjacent protrusions is equal to the interval between two adjacent grooves.
[0014] In some embodiments, the protrusions are evenly distributed on the entire wall surface of the shaft hole or the rotating shaft;
[0015] The grooves are evenly distributed on the entire wall surface of the shaft hole or the rotating shaft.
[0016] In some embodiments, the shaft hole and the rotating shaft are configured such that when the protrusion is located in the groove, the inner wall of the shaft hole fits against the outer wall of the rotating shaft.
[0017] In some embodiments, when the protrusion is located in the groove, the inner wall of the groove fits with the outer wall of the protrusion.
[0018] In some embodiments, when the protective cover is closed, the protrusion is located in the groove.

[0023] The embodiment of the present application provides a wire outlet seat and a battery pack, which realizes the rotation of the protective cover on the seat body through the mutual cooperation between the rotating shaft and the shaft hole, and at the same time, the groove can accommodate at least part of the protrusion, whether the groove completely accommodates the protrusion or partially accommodates the protrusion. When the groove accommodates the protrusion, although there may be a gap between the inner wall of the shaft hole and the outer wall of the rotating shaft, because the thickness of the protrusion is greater than the gap between the inner wall of the shaft hole and the outer wall of the rotating shaft at this time, on the one hand, when the protrusion is rotated to disengage from the groove, the protrusion will abut between the shaft hole and the rotating shaft, thereby forming a blocking force. Under the action of the blocking force, gravity can be prevented from driving the protective cover to rotate back to its original position; on the other hand, when the protrusion is located in the groove, a blocking force is also formed because there is a clamping effect between the groove and the protrusion, which can also prevent gravity from driving the protective cover to rotate back to its original position. Therefore, regardless of whether the protrusion and the groove are in correspondence and engaged, there is a blocking force between the rotating shaft and the shaft hole in the present application, ensuring that the protective cover will not rotate back to its original position due to gravity at any rotation angle after being rotated open, so that the operator does not need to rotate the protective cover again to open it when fixing the bolt, thereby improving production efficiency.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0032] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, an embodiment of the present application provides a wire outlet seat, which includes a seat body 1, a protective cover 3, and a rotation blocking structure. The seat body 1 is provided with one of an axial hole 2 and a rotating shaft 4, and the protective cover 3 is provided with the other of the axial hole 2 and the rotating shaft 4, and the rotating shaft 4 is rotatably connected to the axial hole 2. It is understandable that the seat body 1 can be provided with the axial hole 2 or the rotating shaft 4, and correspondingly, the protective cover 3 can be provided with the rotating shaft 4 or the axial hole 2.
[0033] The rotation blocking structure includes a protrusion 5 and a groove 6 for accommodating at least a portion of the protrusion 5. The protrusion 5 is located on one of the shaft hole 2 and the rotating shaft 4, and the groove 6 is located on the other of the shaft hole 2 and the rotating shaft 4. It is understood that the protrusion 5 can be provided on the inner wall of the shaft hole 2 or on the outer wall of the rotating shaft 4. At the same time, correspondingly, the groove 6 can be provided on the outer wall of the rotating shaft 4 or on the inner wall of the shaft hole 2. The thickness of the protrusion 5 is greater than the gap between the inner wall of the shaft hole 2 and the outer wall of the rotating shaft 4 when the protrusion 5 is located in the groove 6.
[0034] In the present application, the rotation of the protective cover 3 on the seat body 1 is achieved by the mutual cooperation between the rotating shaft 4 and the shaft hole 2. At the same time, the groove 6 can accommodate at least part of the protrusion 5. No matter whether the groove 6 completely accommodates the protrusion 5 or partially accommodates the protrusion 5, when the groove 6 accommodates the protrusion 5, although there may be a gap between the inner wall of the shaft hole 2 and the outer wall of the rotating shaft 4, since the thickness of the protrusion 5 is still greater than the gap between the inner wall of the shaft hole 2 and the outer wall of the rotating shaft 4 at this time, on the one hand, when the rotating shaft 4 is rotated, the protective cover 3 is rotated on the seat body 1. When the protrusion 5 is disengaged from the groove 6, the protrusion 5 will abut between the shaft hole 2 and the rotating shaft 4, forming an interference fit, thereby forming a blocking force. Under the action of the blocking force, gravity can be prevented from driving the protective cover to rotate back to its original position. On the other hand, when the protrusion 5 is located in the groove 6, although there is a gap between the inner wall of the shaft hole 2 and the outer wall of the rotating shaft 4, the engagement between the groove 6 and the protrusion 5 also forms a blocking force, which can also prevent gravity from driving the protective cover to rotate back to its original position. Therefore, regardless of whether the protrusion 5 and the groove 6 are in correspondence and engagement, the present application has a blocking force between the rotating shaft 4 and the shaft hole 2, ensuring that the protective cover will not rotate back to its original position due to gravity at any rotation angle after being rotated open, so that the operator does not need to rotate the protective cover again to open it when fixing the bolt, thereby improving production efficiency.
[0035] It is understandable that the thickness of the above-mentioned protrusion 5 can be designed according to the actual blocking effect, ensuring that the thickness of the protrusion 5 is not too small, resulting in a poor effect and the protective cover still rotating back to its original position due to gravity. Similarly, ensure that the thickness of the protrusion 5 is not too large, resulting in difficulty in rotation or inability to rotate.
[0036] Generally speaking, the thickness of the protrusion 5 is slightly larger than the gap between the inner wall of the shaft hole 2 and the outer wall of the rotating shaft 4 when the protrusion 5 is located in the groove 6 .
[0037] In the present application, the shaft hole 2 and the rotating shaft 4 as well as the protrusion 5 and the groove 6 are arranged and combined to form at least four solutions.
[0038] In the first solution, the axial hole 2 is provided on the base body 1 , the groove 6 is provided on the inner wall of the axial hole 2 , the rotating shaft 4 is provided on the protective cover 3 , and the protrusion 5 is provided on the outer wall of the rotating shaft 4 .
[0039] In the second solution, the rotating shaft 4 is provided on the base body 1 , the protrusion 5 is provided on the outer wall of the rotating shaft 4 , the shaft hole 2 is provided on the protective cover 3 , and the groove 6 is provided on the inner wall of the shaft hole 2 .
[0040] In the third solution, the axial hole 2 is provided on the base body 1 , the protrusion 5 is provided on the inner wall of the axial hole 2 , the rotating shaft 4 is provided on the protective cover 3 , and the groove 6 is provided on the outer wall of the rotating shaft 4 .
[0041] In the fourth solution, the rotating shaft 4 is provided on the base body 1 , the groove 6 is provided on the outer wall of the rotating shaft 4 , the shaft hole 2 is provided on the protective cover 3 , and the protrusion 5 is provided on the inner wall of the shaft hole 2 .
[0042] In some preferred embodiments, along the circumference of the axial hole 2 or the rotating shaft 4, a plurality of protrusions 5 are evenly distributed on at least a portion of the wall surface of the axial hole 2 or the rotating shaft 4. For example, as an example, three protrusions 5 are provided. When the protrusions 5 are distributed on a portion of the wall surface, such as a wall surface formed by a quarter of a circular arc, the three protrusions 5 are evenly distributed on the circumferential wall surface, and the spacing between the first and second protrusions 5 and the spacing between the second and third protrusions 5 are equal; however, the spacing between the third and first protrusions 5 is unequal. In this case, the central angle between the first and second protrusions 5 and the central angle between the second and third protrusions 5 are both 45°, while the central angle between the first and third protrusions 5 is 270°. When the protrusions are distributed on the entire wall surface, the central angle between the first and second protrusions 5, the central angle between the second and third protrusions 5, and the central angle between the first and third protrusions 5 are all 120°. It is understood that the number of the protrusions 5 can be designed according to actual needs.
[0043] Along the circumferential direction of the axial hole 2 or the rotating shaft 4, on the wall surface of the axial hole 2 or the rotating shaft 4, at least part of the wall surface is evenly distributed with multiple grooves 6. The principle of evenly distributing the grooves 6 on part of the wall surface or the entire wall surface is similar to that of the above-mentioned protrusions 5, and will not be repeated here; it can be understood that the number of the above-mentioned grooves 6 can be designed according to actual needs.
[0044] In order to ensure that each protrusion 5 can rotate into the corresponding groove 6 , the interval between two adjacent protrusions 5 is equal to the interval between two adjacent grooves 6 .
[0045] Furthermore, the protrusions 5 are evenly distributed across the entire wall surface of the shaft hole 2 or rotating shaft 4; the grooves 6 are evenly distributed across the entire wall surface of the shaft hole 2 or rotating shaft 4. For example, four grooves 6 and four protrusions 5 are provided, and the central angles of two adjacent protrusions 5 and two adjacent grooves 6 are both 90°. This equal-angle design ensures that when one groove 6 is aligned with a protrusion 5, the remaining grooves 6 are aligned with the corresponding protrusion 5 for engagement.
[0046] Furthermore, the shaft hole 2 and the rotating shaft 4 are configured so that when the protrusion 5 is located in the groove 6, the inner wall of the shaft hole 2 abuts against the outer wall of the rotating shaft 4, and the inner wall of the groove 6 abuts against the outer wall of the protrusion 5. This creates an interference fit between the protective cover and the base 1 during rotation, preventing the protective cover from returning to its original position due to gravity after being opened. "A fit" here means that the gap between the two is essentially zero, although some gap may exist due to manufacturing errors.
[0047] At the same time, when the protrusion 5 is located in the groove 6, the inner wall of the shaft hole 2 is fitted with the outer wall of the rotating shaft 4. The advantage is that the assembly between the rotating shaft 4 and the shaft hole 2 is more stable and not easy to loosen, thereby improving the smoothness of rotation.
[0048] Furthermore, when the protective cover 3 is closed, Figure 4 As shown, when the protective cover 3 is rotated back to its original position, the protrusion 5 is located in the groove 6. Because the protective cover 3 is usually in a closed state, in this state, the protrusion 5 and the rotating shaft 4 or the shaft hole 2 are interference fit. By making the protrusion 5 located in the groove 6, it can be avoided that the protrusion 5 squeezes the rotating shaft 4 or the shaft hole 2 for a long time, causing the rotating shaft 4 or the shaft hole 2 to be deformed or damaged.
[0049] Furthermore, the rotating shaft 4 is a hollow structure, and the middle of the rotating shaft 4 is hollowed out, which can reduce weight and reduce the moment of inertia while maintaining sufficient strength and rigidity.
[0050] Furthermore, the protrusion 5 is spherical and designed to be spherical, so that the protrusion 5 is easier to come out of the groove 6 during rotation, thereby improving the convenience of the rotation operation, making it easier for the operator to rotate the protective cover, and being more operator-friendly. At the same time, the spherical protrusion 5 is in point contact with the inner wall of the shaft hole 2, which not only ensures the existence of the blocking force, but also reduces the friction between the two, and also makes it easier for the operator to rotate the protective cover, and is more operator-friendly.
