[0027] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1: Figures 1 to 4 As shown, one embodiment of the utility model provides a new type of battery, including a shell, and the upper surface of the shell is provided with a wire groove structure for accommodating connecting wires;

[0029] The upper surface of the shell is provided with a positive electrode mounting groove 3 corresponding to the positive electrode of the battery and a negative electrode mounting groove corresponding to the negative electrode of the battery;

[0030] The positive electrode installation groove 3 and the negative electrode installation groove are both connected to the wire-passing groove structure, and the groove depth of the wire-passing groove structure, the groove depth of the positive electrode installation groove 3 and the groove depth of the negative electrode installation groove are all greater than the diameter of the connecting wire.

[0031] Specifically, after lowering the foot pedal on the battery compartment, the battery shell can be directly fixed longitudinally to prevent the battery shell from moving up and down. Since the depths of the wire groove structure, the positive electrode mounting groove 3 and the negative electrode mounting groove are all greater than the diameter of the connecting wire, the wire body of the connecting wire can be accommodated in the wire groove structure when assembling the battery pack, and the two ends of the connecting wire can be accommodated in the positive electrode mounting groove 3 and the negative electrode mounting groove. The foot pedal will not press on the connecting wire and contact the connecting wire, and no friction will be generated between the foot pedal and the connecting wire to cause the connecting wire to break, thereby reducing the occurrence of short circuit or spontaneous combustion.

[0032] Currently, there are designs on the market that lower the height of the battery shell to make it lower than the height of the battery compartment. After the battery pack is placed in the battery compartment, a battery pressure strip is added between the battery shell and the foot pedal to fix the battery shell longitudinally to prevent it from shaking. At the same time, it solves the problem of the foot pedal pressing on the connecting wire and causing friction and breaking the connecting wire. However, this design method may cause the battery pressure strip to press on the connecting wire due to non-standard construction by workers.

[0033] In this embodiment, after lowering the foot pedal on the battery compartment, the upper surface of the shell is against the foot pedal, so that the foot pedal cooperates with the battery compartment to directly fix the battery shell longitudinally, and because the opened wire groove structure, the positive electrode mounting groove 3 and the negative electrode mounting groove can completely accommodate the connecting wire, the foot pedal will not press the connecting wire, and the battery pressure strip can be directly replaced. Compared with the above-mentioned method of preventing the foot pedal from pressing the connecting wire, this solution reduces costs and simplifies the process.

[0034] In addition, since the battery pressure bar is directly replaced, there will be no situation where the battery pressure bar presses on the connecting wire.

[0035] According to one embodiment of the utility model, Figure 2 As shown, the wire groove structure includes a first wire groove 101, a second wire groove 104 and a third wire groove 105 which are interconnected, and the positive electrode mounting groove 3 and the negative electrode mounting groove are both connected to the first wire groove 101. The length direction of the first wire groove 101 is the same as the length direction of the top cover 1 of the housing, and the length of the first wire groove 101 is the same as the length of the top cover 1.

[0036] Specifically, the positive electrode mounting groove 3 and the negative electrode mounting groove are respectively arranged at the two ends of the first wire groove 101, and the second wire groove 104 and the third wire groove 105 are respectively arranged on both sides of the first wire groove 101. The second wire groove 104 and the third wire groove 105 can be provided in plurality. The plurality of second wire grooves 104 are arranged in sequence along the length direction of the first wire groove 101 and are all connected to the first wire groove 101. The plurality of third wire grooves 105 are arranged in sequence along the length direction of the first wire groove 101 and are all connected to the first wire groove 101.

[0037] It should be noted that the length direction of the second wire passing groove 104 and the third wire passing groove 105 is perpendicular to the length direction of the first wire passing groove 101, and the positive electrode installation groove 3 and the negative electrode installation groove are both circular grooves.

[0038] The first wire groove 101, the second wire groove 104, the third wire groove 105, the positive electrode mounting groove 3 and the negative electrode mounting groove are interconnected, so that the wire body of the connecting wire can always be located in the wire groove when connecting the positive and negative electrodes of the battery, and because the groove depths of the positive electrode mounting groove 3 and the negative electrode mounting groove are greater than the diameter of the connecting wire, the two ends of the connecting wire can be accommodated in the positive electrode mounting groove 3 and the negative electrode mounting groove, and thus the connecting wire as a whole will not contact the pedal to generate friction, and the connecting wire will not be broken due to friction to cause short circuit or spontaneous combustion.

[0039] In this embodiment, the first wire passing groove 101, the second wire passing groove 104 and the third wire passing groove 105 are configured as square grooves.

[0040] Of course, in the present embodiment, the groove structures of the first wire passing groove 101, the second wire passing groove 104 and the third wire passing groove 105 can also be arc-shaped grooves, and the opening size at the groove is smaller than 0.1 mm of the connecting wire. Since the foreskin of the connecting wire is soft and can be slightly deformed, the connecting wire can be squeezed into the arc-shaped groove. At this time, since the groove is smaller than the connecting wire, the arc-shaped groove can also play a role in limiting the connecting wire. The diameter of the arc-shaped groove is larger than the diameter of the connecting wire, so that the connecting wire can be accommodated in the arc-shaped groove without generating friction with the groove wall of the arc-shaped groove, thereby providing better protection for the connecting wire.

[0041] Of course, in this embodiment, the first wire groove 101, the second wire groove 104 and the third wire groove 105 can also be in other shapes, such as a trapezoidal groove, the notch of the trapezoidal groove is the upper bottom of the trapezoidal groove, the upper bottom length of the trapezoidal groove is less than the lower bottom length, and the connection line can also be accommodated or the connection line can be limited while being accommodated. Its purpose does not deviate from the design concept of the utility model, and therefore, it should belong to the protection scope of the utility model.

[0042] Of course, in this embodiment, each second wire groove 104 and each third wire groove 105 are preferably on the same straight line, so that the connecting wire takes the shortest route when entering the third wire groove 105 from the second wire groove 104, thereby being able to select a shorter connecting wire, thereby reducing the cost. Its purpose does not deviate from the design concept of the utility model, and therefore, should belong to the protection scope of the utility model.

[0043] Furthermore, in this contact, the widths of the first wire groove 101, the second wire groove 104 and the third wire groove 105 are greater than the diameter of the connecting wire, so that the connecting wire will not generate large friction with the groove side walls, further protecting the connecting wire and making it less likely to break.

[0044] According to an embodiment of the present utility model, a limiting component 5 for limiting the position of the connecting wire is arranged in the wire trough structure.

[0045] A limiting component 5 is provided in the wire groove, and the limiting component 5 can limit the connecting wire in the wire groove structure, so that the connecting wire does not contact the pedal, and the pedal does not press the connecting wire to generate friction between the connecting wires, thereby reducing the occurrence of short circuit or spontaneous combustion of the connecting wire due to broken skin.

[0046] like Figure 3 As shown, the limiting assembly 5 includes a plurality of first limiting blocks 501 for limiting the connection line in the first wire groove 101. The plurality of first limiting blocks 501 in the first wire groove 101 are sequentially arranged on the inner wall of the first wire groove 101 along the length direction of the first wire groove 101, and the distance from the first limiting block 501 to the inner bottom wall of the first wire groove 101 is greater than the diameter of the connection line.

[0047] The connecting wire is placed in the first wire groove 101 , and the first limiting block 501 can limit the connecting wire.

[0048] Specifically, the two inner walls of the first wire groove 101 are recorded as the first inner wall and the second inner wall, and multiple first limit blocks 501 are fixed on the first inner wall and the second inner wall in sequence along the length direction of the first wire groove 101. It should be noted that at this time, the connecting wire can be limited without damaging the wire sheath of the connecting wire.

[0049] Furthermore, the cross-sectional area of ​​one end of the first limit block 501 close to the side wall of the first wire groove 101 is larger than that of the other end, so that the first limit block 501 is fixed to the first wire groove 101 more firmly without hindering the connection line from being placed in the first wire groove 101.

[0050] The first limit block 501 can also be in other forms, for example, the first limit block 501 is an arc plate, the arc plate is made of elastic material, the arc plate is arranged on the inner side wall of the first wire groove 101, and multiple arc plates can be arranged on the same side of the first wire groove 101 or on both sides of the first wire groove 101. When the connecting wire is inserted, the arc plate is pressed down, the arc plate is elastically deformed, and the connecting wire falls under the arc plate, so that the arc plate can achieve the purpose of limiting the connecting wire in the first wire groove 101.

[0051] According to an embodiment of the utility model, the limiting assembly 5 further includes a plurality of second limiting blocks 502 for limiting the connection line in the second wire groove 104. The plurality of second limiting blocks 502 in the second wire groove 104 are sequentially arranged on the inner wall of the second wire groove 104 along the length direction of the second wire groove 104, and the distance from the second limiting blocks 502 to the inner bottom wall of the second wire groove 104 is greater than the diameter of the connection line.

[0052] Of course, in this embodiment, the second limit block 502 can also be in other forms, for example, the second limit block 502 is an arc plate, the arc plate is made of elastic material, and its use method is the same as the first limit block 501. Its purpose does not deviate from the design concept of the utility model, and therefore, it should belong to the protection scope of the utility model.

[0053] According to one embodiment of the utility model, the shell includes a bottom shell 2 and a top cover 1 installed on the bottom shell 2, the top cover 1 includes a bottom plate, and a first wire passing structure and a second wire passing structure are respectively provided on both sides of the bottom plate, and a first wire passing groove 101 is formed between the first wire passing structure and the second wire passing structure.

[0054] Furthermore, a gap is left between the first wire passing structure and the second wire passing structure, thereby forming the first wire passing groove 101. Preferably, the first wire passing structure, the second wire passing structure and the bottom plate are integrally formed by injection molding.

[0055] The top cover 1 and the limiting assembly 5 in the wire trough structure can be processed by one-piece plastic injection molding. The processing technology is simple and fast, which saves costs. At the same time, its unique structure speeds up the fixation and installation process of the battery pack, saving time and effort.

[0056] According to an embodiment of the present invention, the first wire passing structure includes a plurality of first protruding columns 102 arranged at intervals, and a second wire passing groove 104 is formed between every two adjacent first protruding columns 102 .

[0057] Specifically, the heights of the first raised columns 102 are all the same, and the first raised columns 102 are all integrally formed with the base plate. In order to reduce the overall weight of the battery pack, the first raised columns 102 can also be configured to be hollow and thick-walled. Since the first raised columns 102 directly rest against the pedal, and after the battery pack is placed in the battery compartment, the top of the first raised columns 102 is the pedal area of ​​the electric vehicle, and the first raised columns 102 can also support the pedal.

[0058] Of course, in this embodiment, the first wire-passing structure can also be in other forms. For example, the first wire-passing structure is a corrugated plate, and the depth of the corrugated plate is greater than the diameter of the connecting wire, so that the connecting wire can completely enter the corrugated plate. On this basis, since the thickness of the corrugated plate is designed to be 5-8 mm, the strength of the corrugated plate is enhanced, making it less likely to deform. It can also achieve the function of accommodating the connecting wire, so that the foot pedal will not press the connecting wire to generate friction. Its purpose does not deviate from the design concept of the utility model, and therefore, it should belong to the protection scope of the utility model.

[0059] Of course, in this embodiment, the first wire-passing structure can also be a plurality of strip blocks, which are arranged along the length direction of the bottom plate, and each strip block is provided with a slot for accommodating the connecting wire, so that the pedal will not press the connecting wire and then generate friction with the connecting wire. Its purpose does not deviate from the design concept of the utility model, and therefore, it should belong to the protection scope of the utility model.

[0060] According to an embodiment of the present invention, the second wire passing structure includes a plurality of second protruding columns 103 arranged at intervals, and a third wire passing groove 105 is formed between every two adjacent second protruding columns 103 .

[0061] Of course, in this embodiment, the second wire-passing structure can also be in other forms, such as a corrugated plate and a strip block, etc. Its usage is the same as that of the first wire-passing structure, and it can also achieve the limiting effect on the connecting line. Its purpose does not deviate from the design concept of the present utility model, and therefore, it should belong to the protection scope of the present utility model.

[0062] Specifically, in the present embodiment, preferably, the planes where the bottom walls of the positive electrode mounting groove 3, the negative electrode mounting groove, the first wire groove 101, the second wire groove 104 and the third wire groove 105 are located are all located on the same horizontal plane, and no height difference will be generated when the connecting wire is installed in the positive electrode mounting groove 3 or the negative electrode mounting groove through the first wire groove 101, the second wire groove 104 or the third wire groove 105, so that the connecting wire will not be worn by the protruding edges and corners at the height difference position, thereby better protecting the connecting wire and preventing it from being broken.

[0063] Furthermore, the length of the first raised column 102 is greater than the length of the second raised column 103, and multiple first raised columns 102 are arranged at intervals along the length direction of the first wire groove 101, and the length direction of the first raised columns 102 is perpendicular to the length direction of the first wire groove 101, and multiple second raised columns 103 are arranged at intervals along the length direction of the first wire groove 101, and the length direction of the second raised columns 103 is parallel to the length direction of the first wire groove 101.

[0064] According to one embodiment of the utility model, the positive electrode mounting groove 3 and the negative electrode mounting groove are respectively provided with a first screw hole 4 and a second screw hole, the connecting wire is fixed at the first screw hole by a first bolt and connected to the positive electrode of the battery, and the connecting wire is fixed at the second screw hole by a second bolt and connected to the negative electrode of the battery.

[0065] Among them, the plurality of first limiting blocks 501, the plurality of second limiting blocks 502, the first protruding columns 102, the second protruding columns 103 and the bottom plate are integrally formed by injection molding, and the processing technology is simple and rapid.

[0066] A first screw hole 4 and a second screw hole are respectively provided in the positive electrode mounting groove 3 and the negative electrode mounting groove. The end of the connecting wire is fixed to the first screw hole 4 of one of the battery shells by a first bolt and connected to the positive electrode of the battery. The other end of the connecting wire is fixed to the second screw hole 4 of the other battery shell by a second bolt and connected to the negative electrode of the other battery, thereby realizing the series connection of the two batteries.

[0067] Embodiment 2: A battery pack, such as Figure 4 As shown, a new type of battery is included; a plurality of batteries are provided and arranged in a straight line.

[0068] Specifically, one end of the connecting wire is connected to the positive electrode mounting slot 3 of one of the batteries to connect with the positive electrode of the battery, the wire body of the connecting wire is placed in a plurality of wire passing slot structures through which the connecting wire passes, and then the other end is placed in the positive electrode mounting slot 3 or the negative electrode mounting slot of another battery to connect with the positive electrode or the negative electrode of the battery, and a plurality of batteries are connected in series and parallel through a plurality of connecting wires in the above manner to form a battery pack. Since the wire bodies of the plurality of connecting wires are accommodated in a plurality of wire passing slot structures and the ends of the plurality of connecting wires are accommodated in the positive electrode mounting slot 3 or the negative electrode mounting slot, when the battery pack is placed in the battery compartment and the foot pedal is put on to secure the battery pack in the battery compartment, the foot pedal will not contact the connecting wire to generate friction, causing skin breakage and subsequently causing a short circuit or spontaneous combustion.

[0069] In addition, if Figure 4 As shown, this arrangement and placement method can use shorter connecting lines for connection, saving costs.
