[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0041] Reference below Figures 1-12 The protective cover 100 , the terminal assembly and the vehicle according to the embodiment of the present invention are described.

[0042] The protective cover 100 of the present embodiment includes a first plate 1, a second plate 3, and a snap 11. The snap 11 is provided on the first plate 1, and a snap hole is defined in the second plate 3. When the snap 11 is engaged with the snap hole 31, the protective cover 100 is in a wrapped state. In this wrapped state, a receiving cavity 4 for accommodating the wrapped device is formed between the first plate 1 and the second plate 3.

[0043] The protective cover of the embodiment of the present invention has a snap buckle and can be directly fixed to the first plate 1 through the snap buckle 11, that is, the protective cover 100 can be installed and fixed through its own structure without the need for additional components, thereby reducing the number of components used in the power battery and improving the convenience of installation of the protective cover.

[0044] Therefore, the protective cover 100 of the embodiment of the present invention has the advantages of high installation convenience and good operability.

[0045] Optionally, the snap buckle 11 can be injection molded or bonded to the first plate 1 .

[0046] like Figures 1 to 5As shown, the first plate body 1 and the second plate body 3 are connected through the connecting plate 2, and the clamping buckle 11 is arranged at one end of the first plate body 1 away from the connecting plate 2, and the clamping hole 31 is arranged at one end of the second plate body 3 away from the connecting plate 2, and the clamping buckle 11 and the clamping hole 31 are symmetrically arranged relative to the connecting plate 2.

[0047] The protective cover 100 of the embodiment of the utility model, through the first plate body 1 and the second plate body 3 are connected through the connecting plate 2, not only realize the connection of the first plate body 1 and the second plate body 3, also help to realize the pairing installation of the first plate body 1 and the second plate body 3. When needing to install multiple protective covers 100, namely multiple first plate bodies 1 and second plate bodies 3, it is not necessary to further pair the first plate body 1 and the second plate body 3, and further help to improve the convenience of installation.

[0048] Optionally, the first plate body 1, the connecting plate 2 and the second plate body 3 can be adhesively or integrally injection molded.

[0049] The first plate body 1 and the second plate body 2 are located in the same plane, and the protective cover 100 forms an unfolded state. Therefore, it can be understood that the protective cover 100 has an unfolded state and a wrapped state. Therefore, the first plate body 1 and the second plate body 3 are fixed through the clamping buckle 11 structure, and during maintenance, the clamping buckle 11 can be separated from the clamping hole 31, and the position to be maintained can be opened for maintenance. After maintenance is completed, the protective cover 100 is covered on the protection area 400, which is conducive to realizing the reuse of the protective cover 100.

[0050] As shown in Figure 1 and Figure 3 One of the first plate body 1 and the second plate body 3 has a limiting groove 14, and the other of the first plate body 1 and the second plate body 3 has a limiting convex 34, and in the wrapped state, the limiting convex 34 is matched in the limiting groove 14. In other words, the first plate body 1 has a limiting groove 14, and the second plate body 3 has a limiting convex 34; or the second plate body 3 has a limiting groove 14, and the first plate body 1 has a limiting convex 34.

[0051] The protective cover 100 of the embodiment of the utility model, the first plate body 1 and the second plate body 3 are limited and matched through the limiting convex 34 and the limiting groove 14, and when installing the protective cover 100, the first plate body 1, the second plate body 3 can be roughly positioned through the limiting convex 34 and the limiting groove 14. The matching position is prevented from affecting the clamping efficiency due to the misplacement of the plate body during the process of clamping the clamping buckle 11 in the clamping hole 31. Therefore, the cooperation between the limiting convex 34 and the limiting groove 14 has the advantage of further improving the assembly efficiency of the protective cover 100.

[0052] Specifically, the limiting convex 34 extends along the thickness direction of the first plate body 1.

[0053] The first plate 1 has a first surface for forming a receiving cavity, and the second plate 3 has a second surface for forming a receiving cavity. The limiting groove 14 is formed on the first edge of the first surface, and the limiting protrusion 34 is integrally formed on the second edge of the second surface. In the wrapped state, the first and second edges are affixed to each other, and the relative position of the limiting groove 14 on the first edge is the same as the relative position of the limiting protrusion 34 on the second edge. It will be understood that in the wrapped state, the first and second surfaces are disposed opposite each other in the thickness direction of the protective cover 100.

[0054] The protective cover 100 of this embodiment of the utility model has the advantage of a good fixing effect during the fastening of the first plate 1 and the second plate 3 by aligning the relative position of the limiting groove 14 on the first edge with the relative position of the limiting protrusion 34 on the second edge. Moreover, after the positioning is completed, the positioning of other positions can be realized, which helps to improve the installation efficiency of the protective cover 100.

[0055] Specifically, if Figure 1 and Figure 5 As shown, in the unfolded state, the first plate 1 is arranged along a preset direction (for example, Figure 5 ) has an oppositely arranged first end 12 (the first end 12 forms a first edge) and a second end 13, the second end 13 is connected to the connecting plate 2, and the second plate body 3 has an oppositely arranged third end 32 and a fourth end 33 along a preset direction (the fourth end 33 forms a second edge), the third end 32 is connected to the connecting plate 2, the limiting groove 14 is provided in the first plate body 1 near the first edge, and the limiting protrusion 34 is formed in the second plate body 3 near the second edge area. By integrally forming the limiting protrusion 34 in the second plate body 3 near the fourth end 33 area. Furthermore, the protective cover 100 helps to improve the integrity of the structure.

[0056] Furthermore, Figure 5 As shown in FIG, in the unfolded state, the limiting protrusion 34 is located on the upper surface of the first plate 1, and the limiting groove 14 is located on the upper surface of the second plate 3. Furthermore, during installation, the limiting protrusion 34 and the limiting groove 14 are arranged relative to each other in the thickness direction to fix the first plate 1 and the second plate 3.

[0057] Furthermore, the upper end surface of the limiting protrusion 34 has a guide portion 341 that guides the limiting protrusion 34 into the limiting groove 14. Thus, the provided guide portion 341 facilitates the engagement of the limiting protrusion 34 within the limiting groove 14, thereby improving installation convenience. For example, the guide portion 341 can be a chamfered portion formed at the top corner of the limiting protrusion 34.

[0058] The thickness of the first plate 1 and the second plate 3 is 1 mm to 3 mm. The protective cover 100 of the present invention, by setting the thickness of the first plate 1 and the second plate 3 to 1 mm to 3 mm, can avoid operational failures or casualties caused by poor insulation (acid rain or exposed electrical contacts) due to a too-small thickness, while also avoiding the high cost and weight associated with an excessive thickness. Thus, the protective cover 100 of the present invention combines the advantages of cost reduction with excellent insulation.

[0059] Optionally, the thickness of the first plate body 1 and the second plate body 3 may be 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.4 mm, 2.6 mm, 2.8 mm and 3.0 mm.

[0060] The thickness of the connecting plate 2 is 30%-80% of the thickness of the first plate 1 and the second plate 3. It is understood that the thickness of the connecting plate 2 is less than the thickness of the first plate 1. Thus, the embodiment of the utility model facilitates the transition of the protective cover 100 between the unfolded state and the wrapped state.

[0061] like Figure 3 and Figure 5 As shown, when the first plate 1 and the second plate 2 are located in the same plane, the protective cover is in an unfolded state. In this unfolded state, the connecting plate 2 has a bent surface. This bent surface helps maintain the protective cover 100 in the wrapped state without the need for laborious bending of the connecting plate 2. This improves installation convenience.

[0062] The protective cover 100 is made of a flexible material, which has the advantages of being easy to form and easy to install.

[0063] Furthermore, protective cover 100 may be a silicone cover; or a rubber cover. Silicone and rubber covers are highly flexible, tear-resistant, and insulative, and are UV- and aging-resistant. They are suitable for long-term outdoor operation. Furthermore, protective cover 100 in this embodiment of the present invention may be provided with a colored rubber cover, or with different color intervals, to also serve as a phase sequence indicator.

[0064] like Figure 1 and Figure 5 As shown, when there are multiple snap fasteners 11 and snap fastener holes 31, the multiple snap fasteners and the multiple snap fastener holes correspond one to one, and the multiple snap fasteners 11 are arranged at intervals along the circumference of the first plate body 1, and the multiple snap fastener holes 31 are arranged at intervals along the circumference of the second plate body 3.

[0065] The protective cover 100 of the present invention is provided with a plurality of snap fasteners 11, which are arranged on the first plate 1 at intervals along the circumference of the first plate 1, thereby achieving multi-point fixation of the first plate 1 and the second plate 3. As a result, the protective cover 100 improves the overall structural stability.

[0066] Furthermore, the snap fasteners 11 are provided at a position near the first edge of the first plate 1, and after the protective cover 100 is fastened at both ends along a preset direction, the protective cover 100 helps to improve the installation efficiency of the protective cover 100.

[0067] like Figure 3 and Figure 5 As shown, the first plate 1 has a first surface for forming a receiving cavity, and the second plate has a second surface for forming the receiving cavity. The first surface and / or the second surface have a concave surface 35, which forms the receiving cavity. In other words, the first plate 1 has a concave surface 35, the second plate 3 has a concave surface 35, or both the first plate 1 and the second plate 3 have a concave surface 35. The concave surfaces 35 on the plate structures themselves form the receiving cavity. As a result, the protective cover 100 has the advantage of high manufacturing convenience.

[0068] Furthermore, if Figure 3 and Figure 5 As shown, the first surface further has a first bonding plane 15, and the second surface further has a second bonding plane 36. In the wrapped state, the first bonding plane 15 and the second bonding plane 36 are bonded.

[0069] The protective cover 100 of the embodiment of the utility model helps to achieve sealing of the area by fitting the first fitting plane 15 and the second fitting plane 36 in the wrapped state, thereby improving the protection effect of the protective cover 100, avoiding short-circuit failures caused by leakage points in the area, and improving the insulation protection of the insulating circuit.

[0070] Furthermore, the position and size of the concave surface 35 can be set according to the shape and size of the connection bar 200 , the terminal 300 , and the protection area 400 at the connection portion of the connection bar 200 and the terminal 300 .

[0071] like Figure 3 and Figure 8 As shown, the first plate body 1 has a first surface for forming an accommodating cavity, the second plate body has a second surface for forming the accommodating cavity, the first surface and / or the second surface has an avoidance cavity 5 protruding toward the outside of the accommodating cavity, and the orthographic projection of the avoidance cavity 5 toward the accommodating cavity is located within the accommodating cavity 4.

[0072] The protective cover 100 of the embodiment of the present invention is connected to and accommodates the protruding connecting piece through the avoidance cavity 5 protruding outward on the first plate body 1 and / or the second plate body 3.

[0073] Optionally, the connection bar 200 and the terminal 300 may be connected by a connecting member, such as a screw.

[0074] The protective cover 100 of the present invention has an outwardly protruding avoidance cavity 5 in the first plate 1 and / or the second plate 3, so that the position of the connector can be installed. The avoidance cavity 5 can be limited by the connector, thereby improving the positioning of the installation.

[0075] like Figure 6 and Figure 7 As shown, the snap buckle 11 includes a connecting column section 111 and a flexible anti-retreat section 112 arranged in sequence along its extension direction. The two ends of the connecting column section 111 are respectively connected to the first plate body 1 and the flexible anti-retreat section 112. The connecting column section 111 and the flexible anti-retreat section 112 form a limiting step at the connection, and the free end of the flexible anti-retreat section 112 has a guiding head.

[0076] The protective cover 100 of the present invention is characterized in that the snap fastener 11 is divided into a connecting column section 111 and a flexible anti-retraction section 112 arranged in sequence along its extension direction, and the flexible anti-retraction section 112 can be adaptively squeezed into the snap fastener hole 31. Thus, the protective cover 100 has the advantage of high installation convenience.

[0077] Optionally, the snap buckle 11 can be integrally formed on the first plate 1 .

[0078] Specifically, the snap buckle 11 extends along the thickness direction of the protective cover 100, and the snap buckle 11 includes a connecting column section 111 and a flexible anti-retreat section 112 arranged in sequence along its extension direction. The connecting column section 111 is connected to the first plate body 1. In the thickness direction of the protective cover 100, the projection of the connecting column section 111 is within the projection of the flexible anti-retreat section 112. The connecting column section 111 and the flexible anti-retreat section 112 form a limiting step at the connection. In the wrapped state, the connecting column section 111 is passed through the snap hole 31, and the flexible anti-retreat section 112 abuts against the side of the second plate body 3 away from the first plate body 1.

[0079] Alternatively, as Figure 7 As shown, the diameter of the guide head 1121 increases from its free end to a direction close to the connecting column section 111 to form the guide head 1121 .

[0080] The protective cover 100 of the present invention is provided with a guide head 1121 by the flexible anti-retraction section 112, so that the flexible anti-retraction section 112 can be lifted and installed into the corresponding engaging hole 31.
