[0022] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0023] Reference is made below to Figure 1 describe the busbar fixing buckle 100 of the first aspect embodiment of the present invention.

[0024] According to the busbar fixing buckle 100 of the first aspect embodiment of the present invention, the busbar fixing buckle 100 includes: a base 10, a cover 20 and a pressing structure 30.

[0025] Specifically, the cover 20 extends along the first direction (for example Figure 1 the front-back direction shown), and the two ends are respectively a first end and a second end. The first end is rotatably connected to the base 10, and the second end is detachably connected to the base 10. The cover 20 and the base 10 cooperate to define a fixing hole for fixing the busbar; the pressing structure 30 includes an elastic cantilever (for example, the first cantilever and the second cantilever described below), and one end of the elastic cantilever (for example Figure 1 the upper end of the elastic cantilever shown) is connected to the cover 20, and the other end of the elastic cantilever (for example Figure 1The lower end of the elastic cantilever shown) extends towards the base 10 to be adapted to abut against the copper busbar located in the fixing hole. In the direction from the protective cover 20 towards the base 10, the elastic cantilever extends obliquely in a second direction perpendicular to the first direction (for example Figure 1 the left - right direction shown in

[0026] For example Figure 1 As shown, the protective cover 20 extends in the front - rear direction. The rear end of the protective cover 20 is formed as the first end, and the front end is formed as the second end. The first end of the protective cover 20 and the base 10 can be connected by a hinge or can be connected by a connection part that can elastically deform, so as to realize the rotatable connection between the first end and the base 10. The second end of the protective cover 20 and the base 10 can be connected by snap - fit or can be connected by fasteners to facilitate the connection and separation between the second end and the base 10.

[0027] The pressing structure 30 is used to press the copper busbar. It should be noted that the pressing structure 30 can be a structure that can elastically deform, so as to ensure that the pressing structure 30 has sufficient pressing force on the copper busbar through the deformation of the pressing structure 30, so that the copper busbar is stably fixed in the fixing hole. For example, the pressing structure 30 can be a spring structure, a cantilever structure, etc.

[0028] The pressing structure 30 includes an elastic cantilever. The upper end of the elastic cantilever is connected to the protective cover 20, and the lower end extends towards the base 10. In the direction from top to bottom, the elastic cantilever extends towards one side in the left - right direction.

[0029] When it is necessary to fix the copper busbar to the copper - busbar fixing buckle 100, first separate the second end of the protective cover 20 from the base 10. Specifically, rotate the protective cover 20 to open or expose the upper side of the fixing hole. For example, the protective cover 20 can be rotated to a vertical position perpendicular to the base 10, or the protective cover 20 can be rotated to an angle greater than 90° with respect to the base 10. Then, place the copper busbar extending in the left - right direction into the open fixing hole on the base 10. Next, rotate the protective cover 20 to cover the open side of the fixing hole, connect the second end of the protective cover 20 to the base 10, and make the pressing structure 30 abut against the copper busbar, so as to realize the fixation of the copper busbar in the fixing hole of the copper - busbar fixing buckle 100.

[0030] In the prior art, the elastic cantilever fixing holes of the copper bar fixing buckle are arranged in the width direction. In this way, in the width direction of the fixing holes, the elastic cantilever can only be in contact with the copper bar at the free end of the cantilever. When the copper bar deviates from the free end position of the elastic cantilever, for example, when the copper bar shifts along the width direction of the fixing hole and the size of the copper bar is relatively small, for example, when the size of the copper bar is smaller than the distance between the free end of the elastic cantilever and the side wall of the fixing hole in the width direction, the free end of the elastic cantilever cannot contact the copper bar. That is, the elastic cantilever of the copper bar fixing buckle in the prior art has a large fixing blind area in the width direction of the fixing hole. When the copper bar moves to both sides in the thickness direction of the cantilever, the elastic cantilever cannot contact and fix the copper bar.

[0031] In this embodiment, by setting the elastic cantilever to extend obliquely along the second direction, that is, the elastic cantilever extends obliquely along the extending direction of the copper bar, rather than obliquely in the width direction of the copper bar. Thus, not only can it ensure that the other end of the elastic cantilever can effectively contact the copper bar, improving the stability of fixing the copper bar, but also the copper bar fixing buckle can be applicable to copper bars of different widths, improving the versatility.

[0032] For the copper bar fixing buckle 100 according to the embodiment of the present invention, by setting the elastic cantilever of the pressing structure to extend obliquely along the second direction, it can ensure that the other end of the elastic cantilever can effectively contact the copper bar, improving the stability of fixing the copper bar, and the copper bar fixing buckle can also be applicable to copper bars of different widths, improving the versatility.

[0033] According to some embodiments of the present invention, the number of the pressing structures 30 is multiple, and the multiple pressing structures 30 are arranged along the first direction (for example Figure 1 the front-back direction shown) and / or the second direction (for example Figure 1 the left-right direction shown in the figure).

[0034] Among them, the number of the pressing structures 30 is multiple. For example, two, three, four, five or more pressing structures 30 can be set.

[0035] The multiple pressing structures 30 are arranged along the first direction, and the first direction is the width direction of the copper bar. When the copper bar fixing buckle 100 presses the copper bar, the multiple pressing structures 30 can sequentially press the copper bar in the width direction of the copper bar, which is beneficial to making the copper bar fixing more reliable and not prone to crosstalk.

[0036] When the width dimension of the copper bar is small, since the multiple pressing structures 30 are arranged along the width direction of the copper bar, when the copper bar is at any position in the width direction of the fixing hole, there can be a corresponding pressing structure 30 to contact and press the copper bar, avoiding the copper bar from shaking. Thus, the copper bar fixing buckle 100 of this embodiment can fix copper bars of various width dimensions, improving the versatility of the copper bar fixing buckle 100.

[0037] A plurality of pressing structures 30 are arranged at intervals in a second direction perpendicular to the first direction (for example Figure 1 the left - right direction shown). For example Figure 1 as shown, two rows of through - holes 21 are provided on the cover 20 and arranged at intervals in the left - right direction. Each row of through - holes 21 has two through - holes 21 arranged at intervals in the front - rear direction. Among them, two pressing structures 30 are provided along the circumference of each through - hole 21. The two pressing structures 30 at the same through - hole 21 position are arranged at intervals in the front - rear direction, and the first cantilever 31 and the second cantilever 32 of the pressing structure 30 are oppositely arranged at the left - hand side edge and the right - hand side edge of the through - hole 21.

[0038] In this embodiment, by arranging a plurality of pressing structures 30 at intervals in the second direction, the copper - bar fixing buckle 100 can have a plurality of pressing structures 30 to fix the copper bar along the second direction, and thus the copper - bar fixing buckle 100 can fix the copper bar more firmly.

[0039] According to some embodiments of the present utility model, the pressing structure 30 includes: two elastic cantilevers arranged at intervals. The two elastic cantilevers are respectively the first cantilever 31 and the second cantilever 32. The first cantilever 31 and the second cantilever 32 are arranged at intervals in the second direction. One end of the first cantilever 31 (for example Figure 1 the upper end of the first cantilever 31 shown) and one end of the second cantilever 32 (for example Figure 1 the upper end of the second cantilever 32 shown) are both connected to the cover 20. In the direction from the cover 20 towards the base 10, the other end of the first cantilever 31 (for example Figure 1 the lower end of the first cantilever 31 shown) and the other end of the second cantilever 32 (for example Figure 1 the lower end of the second cantilever 32 shown) extend towards each other to be used for abutting against the copper bar.

[0040] In this embodiment, by setting the pressing structure 30 to include the first cantilever 31 and the second cantilever 32, and one end of the first cantilever 31 and one end of the second cantilever 32 are both connected to the cover 20, the other end of the first cantilever 31 and the other end of the second cantilever 32 extend towards each other in the direction from the cover 20 towards the base 10. The first cantilever 31 and the second cantilever 32 have the characteristic of being elastically deformable. When the cover 20 and the base 10 are combined together, one end of the first cantilever 31 and one end of the second cantilever 32 abut against the copper bar and deform, which can further press the copper bar, improve the fixing effect of the copper - bar fixing buckle 100 on the copper bar. At the same time, the pressing structure 30 adopts a cantilever structure, which can make the pressing structure 30 simple and convenient for maintenance.

[0041] Meanwhile, since the first cantilever 31 and the second cantilever 32 are fixed to the cover 20, the pressing structure 30 can be deformed, and the distance between the other end of the pressing structure 30 and the base 10 can be changed, so that the copper bar fixing buckle 100 can fix copper bars of various thicknesses. Therefore, the copper bar fixing buckle 100 can fix copper bars of various thicknesses, improving the versatility of the copper bar fixing buckle 100.

[0042] Furthermore, the first cantilever 31 and the second cantilever 32 are arranged at intervals in a second direction perpendicular to the first direction (for example Figure 1 the left-right direction shown). In this embodiment, by arranging the first cantilever 31 and the second cantilever 32 at intervals in the second direction, the copper bar fixing buckle 100 can sequentially pass through the first cantilever 31 and a second cantilever 32 along the second direction to fix the copper bar, making the copper bar fixing buckle 100 fix the copper bar more firmly.

[0043] According to some embodiments of the present invention, a through hole 21 penetrating the cover 20 in the thickness direction is formed on the cover 20, and one end of the first cantilever 31 and one end of the second cantilever 32 are respectively connected to opposite side edges of the through hole 21.

[0044] In this embodiment, by providing a through hole 21 formed in the cover 20 and penetrating the cover 20 in the thickness direction, and one end of the first cantilever 31 and one end of the second cantilever 32 are respectively connected to opposite side edges of the through hole 21, the structure of the copper bar fixing buckle 100 can be simplified, facilitating the processing and forming of the first cantilever 31 and the second cantilever 32, reducing the weight of the copper bar fixing buckle 100, and achieving lightweight. In addition, the through hole 21 on the cover 20 can dissipate the heat generated by the copper bar.

[0045] According to some embodiments of the present invention, the number of the through holes 21 is multiple, and one or more pressing structures 30 are arranged along the circumference of any one of the through holes 21.

[0046] For example Figure 1 as shown, two, three, four, five, six or more through holes 21 can be provided on the cover 20. The multiple through holes 21 can be arranged in a rectangular pattern on the cover 20, and one, two or three or more pressing structures 30 can be arranged along the edge of each through hole 21.

[0047] In this embodiment, by providing multiple through holes 21, the heat dissipation effect on the copper bar can be further improved, and the structural strength of the cover 20 can be ensured while reducing the weight of the cover 20. In addition, arranging multiple pressing structures 30 along the circumference of the through hole 21 can make the structure compact, and thus improve the effect of the copper bar fixing buckle 100 in fixing the copper bar.

[0048] According to some embodiments of the present utility model, a first connection hole 12 is provided on the base 10, and a second connection hole 23 is formed at the second end. The first connection hole 12 and the second connection hole 23 are opposite and communicate with each other in the thickness direction of the base 10 (for example Figure 1 the up-and-down direction shown), and the copper busbar fixing buckle 100 is configured to be fixed to the box body of the battery pack by the stud of the battery pack passing through the first connection hole 12.

[0049] In this embodiment, by providing that the second connection hole 23 at the second end is opposite and communicates with the first connection hole 12 on the base 10 in the thickness direction of the base 10, the stud of the battery pack can pass through the first connection hole 12 to fix the copper busbar fixing buckle 100, and at the same time, the first connection hole 12 and the second connection hole 23 can provide a receiving space for the stud of the battery pack. When the traditional copper busbar fixing buckle 100 is connected to the battery pack, it is necessary to open holes in the housing of the battery pack for connection with the copper busbar fixing buckle 100 or use an adapter with connection holes for connection with the copper busbar fixing buckle 100. Compared with the connection between the traditional copper busbar fixing buckle 100 and the battery pack, in this embodiment, the stud is connected to the first connection hole 12 and the second connection hole 23, which can avoid opening holes in the battery pack housing, avoid damaging the sealing performance of the battery pack, and can also simplify the assembly.

[0050] According to some embodiments of the present utility model, the copper busbar fixing buckle 100 may further include an anti-disengagement member. The anti-disengagement member is provided on the base 10. The anti-disengagement member includes a plurality of clamping plates 40. The plurality of clamping plates 40 are arranged at intervals along the circumferential direction of the first connection hole 12. The clamping plates 40 extend along the axial direction of the first connection hole 12 (for example Figure 1 the up-and-down direction shown). One end of the clamping plate 40 facing the first connection hole 12 is formed with a tooth portion. The tooth portion has anti-disengagement teeth. In the direction from the outside to the inside in the radial direction of the first connection hole 12, the anti-disengagement teeth extend obliquely towards the cover 20, and the tooth portion is engaged with the thread of the stud through the anti-disengagement teeth.

[0051] Among them, the anti-disengagement member may be integrally formed with the base 10, or the anti-disengagement member and the base 10 may be two independent components. The anti-disengagement member may include two, three, four or more clamping plates 40. Preferably, the clamping plate 40 is a flat plate extending along the axial and radial directions of the first connection hole 12.

[0052] As Figure 1 shown, the tooth portion of the clamping plate 40 has a plurality of anti-disengagement teeth, and the plurality of anti-disengagement teeth are arranged in sequence in the up-and-down direction. Among them, the cover 20 is arranged on the upper side of the base 10. In the direction from the outside to the inside in the radial direction of the first connection hole 12, the anti-disengagement teeth extend obliquely upwards.

[0053] When fixing the copper bar fixing buckle 100 to the battery pack, align the first connection hole 12 and the second connection hole 23 with the studs on the battery pack, and then pass the studs through the first connection hole 12 and the second connection hole 23 in sequence. Since the inclination direction of the anti - detachment teeth is the same as the insertion direction of the studs, the studs can be smoothly inserted into the copper bar fixing buckle 100. When the copper bar fixing buckle 100 is subjected to an external force and is about to be disengaged from the stud, since the inclination direction of the anti - detachment teeth is opposite to the detachment direction of the stud, at this time, the anti - detachment teeth abut against the thread grooves on the thread, thereby preventing the copper bar fixing buckle 100 from falling off the stud.

[0054] The anti - detachment member is located on the base 10. A plurality of clamping plates 40 are arranged at intervals in the circumferential direction of the first connection hole 12, and the clamping plates 40 extend axially. A tooth portion is formed at one end of the clamping plate 40 facing the first connection hole 12. In this embodiment, by providing a tooth portion with anti - detachment teeth on the clamping plate 40, the tooth portion can be engaged with the thread of the stud through the anti - detachment teeth. In this way, the copper bar fixing buckle 100 can move in the thickness direction of the base 10 towards the stud, and can prevent the copper bar fixing buckle 100 from moving away from the stud in the thickness direction of the base 10. Thus, it can be avoided that the copper bar fixing buckle 100 falls off and the copper bar fixing buckle 100 can be firmly fixed to the stud. At the same time, by using the anti - detachment teeth of the tooth portion of the clamping plate 40 to cooperate with the thread of the stud, the anti - detachment member is simple and convenient for maintenance.

[0055] According to some embodiments of the present invention, a hook 22 is formed on one of the second ends and the base 10, and a clamping hole 11 is formed on the other. The hook 22 is fitted into the clamping hole 11 to make the second end and the base 10 be clamped and connected.

[0056] When the hook 22 is formed on the second end, the clamping hole 11 is formed on the base 10. When the clamping hole 11 is formed on the second end, the hook 22 is provided on the base 10. The hook 22 passes through the clamping hole 11 and is clamped with the peripheral edge of the clamping hole 11.

[0057] In this embodiment, by providing the hook 22 located at the second end to cooperate with the clamping hole 11 on the base 10, it is convenient to fix and separate the second end and the base 10, which is convenient for the copper bar fixing buckle 100 to fix the copper bar and for the copper bar to be disassembled from the copper bar fixing buckle 100. At the same time, by using the cooperation of the hook 22 and the clamping hole 11, the structure of the copper bar fixing buckle 100 is simple and convenient for processing and production.

[0058] According to some embodiments of the present invention, the number of the hooks 22 is multiple. The multiple hooks 22 are respectively arranged on both sides of the first connection hole 12 in the second direction. The first direction is perpendicular to the second direction, and the hooks 22 located on both sides of the first connection hole 12 are arranged at an included angle.

[0059] The protective cover 20 is provided with a plurality of hooks 22. For example, two, three, four or more hooks 22 can be provided on the protective cover 20. As Figure 1 shown, two hooks 22 are provided on the protective cover 20, and the two hooks 22 are respectively arranged on the left and right sides of the second connection hole 23. Among them, the two hooks 22 are inclined with respect to both the left-right direction and the front-back direction, and the hooks 22 on the left and right sides of the second connection hole 23 are symmetrically arranged.

[0060] In this embodiment, by arranging a plurality of hooks 22 on both sides of the first connection hole 12 in the second direction, and the hooks 22 located on both sides of the first connection hole 12 are arranged at an angle, the hooks 22 and the hook holes 11 can fix the protective plate and the base 10 from more directions, thereby improving the fixation of the copper bar fixing buckle 100 to the copper bar.

[0061] According to the battery pack of the second aspect embodiment of the present invention, the battery pack includes: a copper bar and the copper bar fixing buckle 100 according to the first aspect embodiment of the present invention. The copper bar is passed through the fixing hole, and the pressing structure 30 abuts against the copper bar.

[0062] According to the battery pack of the embodiment of the present invention, by setting the battery pack to include the copper bar fixing buckle 100 of the above first aspect embodiment, and the elastic cantilever of the pressing structure extends obliquely along the second direction, it can ensure that the other end of the elastic cantilever can effectively abut against the copper bar, improve the stability of the copper bar fixation, and can also make the copper bar fixing buckle 100 applicable to copper bars of different widths, improving the versatility.
