Detailed Implementation
[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] This utility model provides a vehicle body structure and an electric vehicle. Several embodiments are given below to describe the vehicle body structure and electric vehicle provided by this utility model in detail.
[0027] Example 1
[0028] The vehicle body structure provided in this embodiment, such as Figures 1 to 3 As shown, it includes a battery mechanism and a foot pedal mechanism; the battery mechanism includes a battery base 1, a battery top cover 2, and multiple batteries 3; the multiple batteries are all disposed in the battery base 1, and the battery top cover 2 is disposed on top of the multiple batteries; the multiple batteries 3 are connected by a connecting wire 4; the battery top cover 2 has a groove 21, and the connecting wire 4 is disposed in the groove 21; the foot pedal mechanism includes a foot pedal 5 and a support member 51; the support member 51 is connected to the bottom surface of the foot pedal 5, the foot pedal 5 covers the battery top cover 2, and the support member 51 is in contact with the top surface of the battery top cover 2.
[0029] Multiple batteries 3 are placed inside the battery base 1. The battery base 1 has a support surface, and the edge of the support surface is provided with an annular sidewall 11. Multiple batteries 3 are placed on the support surface, and the annular sidewall 11 is arranged around the outside of the multiple batteries 3, which can limit the multiple batteries 3 and make the multiple batteries 3 stably placed inside the battery base 1.
[0030] There may be a gap between the annular sidewall 11 and the multiple batteries 3, or the annular sidewall 11 and the multiple batteries 3 may be fitted together.
[0031] A battery cover 2 is placed on top of multiple batteries 3. The multiple batteries 3 are connected by connecting wires 4 to provide electrical connection between them.
[0032] The battery cover 2 has a groove 21 located below the top surface of the battery cover 2. The connecting wire 4 is embedded in the groove 21 and does not protrude from the groove 21. When the foot pedal 5 is installed on the battery cover 2, the support 51 is pressed against the top surface of the battery cover 2. The connecting wire 4 is located in the groove 21 below the top surface of the battery cover 2, which can prevent the support 51 from pressing the connecting wire 4. Furthermore, during the assembly process, there is no need to pay attention to prevent the support 51 from pressing the connecting wire 4, making the operation simpler and more foolproof.
[0033] The routing position of the connecting line 4 is clearly defined by the groove 21. The other large areas of the battery cover 2, except for the groove 21, can be used to press with the support 51, making the arrangement of the support 51 simpler and more uniform. This allows the vehicle structure to be used for various versions of the foot pedal 5 (with different distribution patterns of the support 51), improving the versatility of the foot pedal 5, reducing mold development, and lowering costs.
[0034] Different battery covers 2 can be designed according to different battery types 3, making the battery cover 2 modular for later assembly selection, reducing mold development costs, and making it easier to design and port modules.
[0035] The vehicle body structure provided in this embodiment has low cost, is easy to operate, has a good effect in preventing the support component 51 from pressing the connecting line 4, and has strong versatility.
[0036] In this embodiment, the outer contour of each battery 3 is cubic, and multiple batteries 3 are distributed in a rectangular matrix.
[0037] Multiple batteries 3 are arranged in a rectangular matrix. Adjacent batteries 3 can be spaced out or placed together.
[0038] In this embodiment, there are four batteries 3. The first direction is the left-right direction in the figure, and the second direction is the front-back direction in the figure. Two rows of batteries 3 are arranged along the first direction, and two batteries 3 are arranged in each row along the second direction, so that the four batteries 3 are distributed in a rectangular matrix. The first direction is as follows: Figure 3 The direction indicated by the middle arrow ab, the second direction is as follows Figure 3 The direction indicated by the middle arrow cd.
[0039] Furthermore, along the first direction, one end of the battery cover 2 is provided with a first limiting member 22, and the sidewalls of each battery 3 located at one end of the plurality of batteries 3 are in contact with the first limiting member 22; along the first direction, the other end of the battery cover 2 is provided with a second limiting member 23, and the sidewalls of each battery 3 located at the other end of the plurality of batteries 3 are in contact with the second limiting member 23.
[0040] Specifically, along the first direction, a first limiting member 22 is provided at the left end of the battery cover 2, and the left sidewall of each battery 3 located at the leftmost end of the plurality of batteries 3 is in contact with the first limiting member 22; along the first direction, a second limiting member 23 is provided at the right end of the battery cover 2, and the right sidewall of each battery 3 located at the rightmost end of the plurality of batteries 3 is in contact with the second limiting member 23. Under the action of the first limiting member 22 and the second limiting member 23, the plurality of batteries 3 can be limited along the first direction, so that the plurality of batteries 3 are more stably placed on the battery base 1.
[0041] In this embodiment, both the first limiting member 22 and the second limiting member 23 are sheet-like.
[0042] There can be one or more first limiting members 22. When there is one first limiting member 22, the left sidewalls of the leftmost batteries 3 are all in contact with this one first limiting member 22. When there are multiple first limiting members 22, the multiple first limiting members 22 are spaced apart along the second direction, and the left sidewalls of the leftmost batteries 3 are respectively set one-to-one with the multiple first limiting members 22. For example, along the first direction, the left sidewalls of the two leftmost batteries 3 of the four batteries are respectively set one-to-one with the two first limiting members 22.
[0043] There can be one or more second limiting members 23. When there is one second limiting member 23, the right sidewalls of the rightmost batteries 3 are all in contact with this one second limiting member 23. When there are multiple second limiting members 23, the multiple second limiting members 23 are spaced apart along the second direction, and the right sidewalls of the rightmost batteries 3 are respectively set one-to-one with the multiple second limiting members 23. For example, along the first direction, the right sidewalls of the two rightmost batteries 3 of the four batteries are respectively set one-to-one with the two second limiting members 23.
[0044] Furthermore, along the second direction, a third limiting member is provided at one end of the battery cover 2, and the sidewalls of each battery 3 located at one end of the plurality of batteries 3 are in contact with the third limiting member; along the second direction, a fourth limiting member 24 is provided at the other end of the battery cover 2, and the sidewalls of each battery 3 located at the other end of the plurality of batteries 3 are in contact with the fourth limiting member 24; the first direction is perpendicular to the second direction.
[0045] Specifically, along the second direction, the front end of the battery cover 2 is provided with a third limiting member, and the front side wall of each of the multiple batteries 3 located at the foremost position is in contact with the third limiting member; along the second direction, the rear end of the battery cover 2 is provided with a fourth limiting member 24, and the rear side wall of each of the multiple batteries 3 located at the rearmost position is in contact with the fourth limiting member 24. Under the action of the third limiting member and the fourth limiting member 24, the multiple batteries 3 can be limited along the second direction, so that the multiple batteries 3 are more stably placed on the battery base 1.
[0046] In this embodiment, both the third limiting member and the fourth limiting member 24 are sheet-like.
[0047] There can be one or more third limiting members. When there is one third limiting member, the front sidewalls of the foremost batteries 3 are all in contact with this single third limiting member. When there are multiple third limiting members, they are spaced apart along the first direction, and the front sidewalls of the foremost batteries 3 are respectively set one-to-one with the multiple third limiting members. For example, along the second direction, the front sidewalls of the two foremost batteries 3 out of four batteries are respectively set one-to-one with the two third limiting members.
[0048] The fourth limiting member 24 can be one or more. When there is one fourth limiting member 24, the rear end sidewalls of the multiple batteries 3 located at the rearmost end of the multiple batteries 3 are all in contact with this one fourth limiting member 24. When there are multiple fourth limiting members 24, the multiple fourth limiting members 24 are spaced apart along the first direction, and the rear end sidewalls of the multiple batteries 3 located at the rearmost end of the multiple batteries 3 are respectively set to correspond one-to-one with the multiple fourth limiting members 24. For example, along the second direction, the rear end sidewalls of the two batteries 3 located at the rearmost end of the four batteries 3 are respectively set to correspond one-to-one with the two fourth limiting members 24.
[0049] Furthermore, the battery cover 2 is provided with a plurality of protrusions 25, and a groove 21 is formed between adjacent protrusions 25.
[0050] The connecting wire 4 is placed in the groove 21, and the support 51 is pressed against the top surface of the protrusion 25. The top surface of the protrusion 25 forms the top surface of the battery cover 2, which can prevent the support 51 from pressing the connecting wire 4.
[0051] In addition to the groove 21, the battery cover 2 has a large area where protrusions 25 can be arranged. The top surface of the protrusions 25 with a large area can be pressed against the support member 51, which can facilitate the arrangement of the support member 51 and make the support member 51 more evenly distributed.
[0052] Furthermore, the battery cover 2 is provided with a hollow structure 26, which is used to expose the connection area 41 between the connecting wire and the battery.
[0053] The hollow structure 26 is located below the top surface of the protrusion 25. The hollow structure 26 exposes the connection area 41 between the connecting wire and the battery, which facilitates the connection between the connecting wire 4 and the battery. The top surface of the protrusion 25 is located above the hollow structure 26. The support member 51 is pressed against the top surface of the protrusion 25, which can prevent the support member 51 from pressing down on the connection area 41 between the connecting wire and the battery.
[0054] Furthermore, the support member 51 is block-shaped.
[0055] In this embodiment, the support member 51 is a cylindrical block, which enables the support member 51 to support the foot pedal 5 relatively stably.
[0056] The support member 51 can be fixed to the bottom surface of the foot pedal 5 by means of bonding or welding, or the support member 51 can be an integral structure with the foot pedal 5.
[0057] Furthermore, there are multiple support members 51, which are spaced apart. The multiple support members 51 support the foot pedal 5 at different positions, making the foot pedal 5 more stable.
[0058] Multiple support members 51 can be evenly spaced along the first direction to ensure that the multiple support members 51 are evenly distributed and to support the foot pedal 5 more stably.
[0059] After the support member 51 is pressed against the top surface of the battery cover 2, the foot pedal 5 is fixedly connected to other parts of the vehicle body structure to secure the foot pedal 5 to the vehicle body structure. The specific connection position is consistent with the prior art and will not be described again here. After the foot pedal 5 is fixedly connected to other parts of the vehicle body structure, it can press down on multiple batteries 3, so that the multiple batteries 3 are stably placed between the battery base 1 and the foot pedal 5.
[0060] Example 2
[0061] The electric vehicle provided in this embodiment includes the vehicle body structure provided in Embodiment 1. The electric vehicle can be an electric bicycle. A groove 21 is provided on the battery cover 2, located below the top surface of the battery cover 2. The connecting wire 4 is embedded in the groove 21 and does not protrude from it. When the foot pedal 5 is installed on the battery cover 2, the support member 51 presses against the top surface of the battery cover 2. The connecting wire 4 is located in the groove 21 below the top surface of the battery cover 2, preventing the support member 51 from pressing against the connecting wire 4. Furthermore, during assembly, there is no need to constantly pay attention to preventing the support member 51 from pressing against the connecting wire 4, making operation simpler and more foolproof. The groove 21 clearly defines the routing position of the connecting wire 4. Large areas of the battery cover 2, excluding the groove 21, can be used to press against the support member 51, making the arrangement of the support member 51 simpler and more uniform. This allows the vehicle body structure to accommodate various versions of the foot pedal 5 (with different distributions of the support member 51), improving the versatility of the foot pedal 5, reducing mold development, and lowering costs. Different battery covers 2 can be designed according to different battery types 3, making the battery cover 2 modular for later assembly selection, reducing mold development costs, and making it easier to design and port modules.
