Description

Technical Field

[0001] This invention relates to the field of new energy batteries, specifically a new energy vehicle battery cover with a protective mechanism. Background Technology

[0002] New energy vehicles are cars powered by unconventional energy sources. Pure electric vehicles are an important component of new energy vehicles, accounting for a large proportion of my country's new energy vehicle development. Different vehicle specifications are distinguished by their range. The number of batteries is the main factor supporting the range of a car. This mainly involves placing battery compartments of different capacities in the same car model, which requires installing battery packs of different capacities. This increases the cost of mold making for the car, and the empty space where the battery compartment is installed also needs to be filled with fixed cushioning material, increasing the cost of purchasing car parts. The battery compartment parts of different specifications are not interchangeable due to size differences, which brings great trouble to maintenance and replacement. Moreover, since the batteries are fixed, it is not convenient to add or modify batteries later, nor is it convenient to recycle and reuse them. Summary of the Invention

[0004] The technical solution adopted by the present invention to solve its technical problem is: a new energy vehicle battery cover with a protective mechanism, including a battery compartment, protective mechanisms for safety protection are provided on both sides of the battery compartment, a loading mechanism for installing batteries is provided inside the battery compartment, a driving mechanism for adjusting the size of the loading mechanism is provided inside the battery compartment, and a support mechanism abuts on both sides of the loading mechanism, the support mechanism being used to support and stabilize the loading mechanism.

[0005] Specifically, the protective mechanism includes an upper cover and a bottom cover. The top of the battery compartment is provided with an upper cover, and the bottom of the battery compartment is provided with a bottom cover. Each of the upper cover and the bottom cover has a protective strip on its opposite side. The upper cover and the bottom cover are connected to the battery compartment through the protective strip. A connecting bolt is connected between the upper cover and the bottom cover. The connecting bolt fixes the upper cover and the bottom cover to both sides of the battery compartment.

[0006] Specifically, the protective mechanism also includes a horizontal support plate and a vertical support plate. The interior of the upper cover and the bottom cover are both hollow. The interior of the upper cover and the bottom cover are respectively provided with a horizontal support plate and a vertical support plate. The horizontal support plate and the vertical support plate are integrally formed. The interior of the horizontal support plate and the vertical support plate is divided into multiple hollow grooves.

The battery compartment is provided with the first mounting plate and the second mounting plate. Both the first mounting plate and the second mounting plate are rectangular in shape and are slidably connected. The first mounting plate has two telescopic plates slidably connected inside, and the telescopic plates are fixedly connected to the second mounting plate.

[0008] Specifically, the loading mechanism further includes a first track groove. A first track groove is provided on each side of the first mounting plate. The first track groove is fixedly connected to the inner wall of the battery compartment. Two first protrusions and two second protrusions are slidably connected inside the first track groove. The first protrusions are fixedly connected to the side wall of the first mounting plate, and the second protrusions are fixedly connected to the side wall of the second mounting plate. Two parallel track limiting strips are fixedly connected to the bottom inside the battery compartment. The first mounting plate and the second mounting plate are slidably connected to the track limiting strips respectively.

[0009] Specifically, the drive mechanism includes a first lead screw, which is rotatably connected inside the first track groove. The first lead screw is threadedly connected to a first protrusion and a second protrusion, respectively. The internal threads of the first protrusion and the second protrusion are in opposite directions. A first bevel tooth is fixedly connected to one end of the first lead screw located outside the first track groove. A first rotating shaft is rotatably connected inside the battery compartment. A second bevel tooth is fixedly connected to each end of the first rotating shaft. The first bevel tooth and the second bevel tooth mesh with each other. A third bevel tooth is fixedly connected to the middle of the first rotating shaft. A fourth bevel tooth meshes with one side of the third bevel tooth. A first drive block is fixedly connected to one side of the fourth bevel tooth.

[0010] Specifically, the support mechanism includes a second track groove. The battery compartment has two symmetrical second track grooves inside. Two sliders are slidably connected inside the second track groove. A second lead screw is rotatably connected inside the second track groove. A second drive block is fixedly connected to one end of the second lead screw located outside the second track groove. The second lead screw and the slider are threadedly connected. The two sliders have opposite internal directions.

[0011] Specifically, the support mechanism also includes a contact plate, with the first mounting plate and the second mounting plate respectively abutting against each other on opposite sides.

[0012] The beneficial effects of this invention are:

[0013] (1) The new energy vehicle battery cover with a protective mechanism described in this invention provides convenient protection for the top and bottom of the battery compartment through the setting of the upper cover and the bottom cover. The interior of the cover is divided into multiple high-pressure spaces with independent cavity slots by the horizontal support plates and the vertical support plates, which increases the elasticity of the cover. Even if the cover is impacted, it will be hindered by the multiple cavity slots to prevent puncture and improve the safety protection level of the battery. The loading mechanism allows for easy adjustment of the installation space according to the battery capacity requirements. The support mechanism used to secure the battery and provide a buffer is also movable and adjustable, which makes it convenient to install batteries of different capacities in the same mold, which is convenient for use in cars with different prices, reduces the cost of parts procurement, and makes the parts universal and convenient.

[0023] In the description of this invention, it should be understood that the terms "center," "longitudinal," and "center" are used interchangeably.

[0024]

[0025] The orientations or positional relationships indicated by terms such as "straight," "horizontal," "top," "bottom," "inner," and "outer" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of the invention, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-7As shown, the present invention provides a new energy vehicle battery cover with a protective mechanism, including a battery compartment 1. The battery compartment 1 has protective mechanisms 2 on both sides for protection. The battery compartment 1 has a loading mechanism 3 for installing batteries inside. The battery compartment 1 also has a driving mechanism 4 for adjusting the size of the loading mechanism 3 inside. The loading mechanism 3 has a support mechanism 5 on each side, which supports and stabilizes the loading mechanism 3.

[0029] Specifically, the protective mechanism 2 includes an upper cover 21 and a bottom cover 22. The top of the battery compartment 1 is provided with an upper cover 21, and the bottom of the battery compartment 1 is provided with a bottom cover 22. Each of the upper cover 21 and the bottom cover 22 has a protective strip 23 on its opposite side. The upper cover 21 and the bottom cover 22 are connected to the battery compartment 1 through the protective strip 23. A connecting bolt 24 connects the upper cover 21 and the bottom cover 22. The connecting bolt 24 fixes the upper cover 21 and the bottom cover 22 to both sides of the battery compartment 1.

[0030] Specifically, the protective mechanism 2 further includes a horizontal support piece 25 and a vertical support piece 26. The interiors of the upper cover 21 and the bottom cover 22 are both hollow. The upper cover 21 and the bottom cover 22 are respectively provided with a horizontal support piece 25 and a vertical support piece 26. The horizontal support piece 25 and the vertical support piece 26 are integrally formed, and the interiors of the horizontal support piece 25 and the vertical support piece 26 are divided into multiple hollow slots 27. The battery compartment 1 has the upper cover 21 at its top and the bottom cover 22 at its bottom. Both the upper cover 21 and the bottom cover 22 have multiple horizontal support pieces 25 and vertical support pieces 26 inside. The support piece 26 divides the cavity inside the cover plate into multiple independent cavity slots 27. The cavity slots 27 are filled with air, which reduces the amount of material used in the cover plate, reduces the overall weight of the car, reduces the car load, and improves the car's range. On the other hand, it also increases the strength of the cover plate. Even if the cover plate is punctured by a foreign object, the air inside one of the punctured cavity slots 27 escapes rapidly, offsetting the impact force of the foreign object. The kinetic energy of the foreign object is further reduced as it passes through each cavity slot 27. Furthermore, the cavity slots 27 are multi-layered, providing multi-layered protection. In addition, the upper cover 21 and the bottom cover 22 have the same shape and are common components.

[0031] Specifically, the loading mechanism 3 includes a first mounting plate 31 and a second mounting plate 32. The battery compartment 1 is provided with the first mounting plate 31 and the second mounting plate 32. Both the first mounting plate 31 and the second mounting plate 32 are rectangular. The first mounting plate 31 and the second mounting plate 32 are slidably connected. The first mounting plate 31 has two telescopic plates 33 slidably connected inside. The telescopic plates 33 are fixedly connected to the second mounting plate 32.

[0032] Specifically, the loading mechanism 3 further includes a first track groove 37. A first track groove 37 is provided on each side of the first mounting plate 31. The first track groove 37 is fixedly connected to the inner wall of the battery compartment 1. Two first protrusions 34 and two second protrusions 35 are slidably connected inside the first track groove 37. The first protrusions 34 are fixedly connected to the first mounting plate 31 on the side wall. The second protrusions 35 are fixedly connected to the side wall of the second mounting plate 32. Two parallel track limiting strips 36 are fixedly connected to the bottom inside the battery compartment 1. The first mounting plate 31 and the second mounting plate 32 are slidably connected to the track limiting strips 36 respectively.

[0033] Specifically, the drive mechanism 4 includes a first lead screw 41, which is rotatably connected inside the first track groove 37. The first lead screw 41 is threadedly connected to a first protrusion 34 and a second protrusion 35, respectively. The internal threads of the first protrusion 34 and the second protrusion 35 are in opposite directions. A first bevel tooth 42 is fixedly connected to one end of the first lead screw 41 located outside the first track groove 37. A first rotating shaft 43 is rotatably connected inside the battery compartment 1. A second bevel tooth 44 is fixedly connected to each end of the first rotating shaft 43. The first bevel tooth 42 and the second bevel tooth 44 mesh with each other. A third bevel tooth 45 is fixedly connected to the middle of the first rotating shaft 43. A fourth bevel tooth 45 meshes with one side of the third bevel tooth 45. The fourth bevel tooth 46 is fixedly connected to a first drive block 47 on one side. First, the size of the battery pack needs to be determined in advance based on the range requirements of the new energy vehicle. Then, an external tool is inserted into the first drive block 47, and the tool is used to rotate the first drive block 47. The first drive block 47 drives the fourth bevel tooth 46 to rotate. The fourth bevel tooth 46 drives the first rotating shaft 43 to rotate by meshing with the third bevel tooth 45. The first rotating shaft 43 rotates synchronously through the meshing of two second bevel teeth 44 with the first bevel teeth 42 at both ends. This causes the two first lead screws 41 to rotate synchronously. The first protrusion 34 and the second protrusion 35, connected to the same first rotating shaft 43, also rotate synchronously. The internal threads of the first and second protrusions 34 and 35 are in opposite directions, which facilitates adjustment of the distance between them. The first protrusion 34 moves the first mounting plate 31, and the second protrusion 35 moves the second mounting plate 32. After the first and second mounting plates 31 and 32 move, the space between them can be adjusted, allowing for adjustment of the installation space according to the number of batteries. After the batteries are placed, the first lead screw 41 is rotated in the same direction as before, driving the first and second mounting plates 31 and 32 to move closer together, thus shortening the gap with the batteries and securing them firmly. When replacing or adding a new battery later, the first mounting plate 31 and the second mounting plate 32 can be loosened again to replace the new battery. This avoids the traditional one-time fixed battery operation, making later maintenance and recycling more convenient. The same mold can be used to replace batteries with different capacities according to different car requirements, avoiding frequent mold opening and manufacturing, reducing production costs, and maintaining the commonality between electromagnetic compartment parts. The cost of replacing parts later is also relatively small. The telescopic plate 33 is provided between the first mounting plate 31 and the second mounting plate 32. The telescopic plate 33 mainly plays the role of improving the sliding stability of the two and supplementing the sliding gap, suppressing the loosening between the first mounting plate 31 and the second mounting plate 32.

[0034] Specifically, the support mechanism 5 includes a second track groove 51. The battery compartment 1 has two symmetrical second track grooves 51 inside. Two sliders 54 are slidably connected inside the second track groove 51. A second lead screw 52 is rotatably connected inside the second track groove 51. A second drive block 53 is fixedly connected to one end of the second lead screw 52 located outside the second track groove 51. The second lead screw 52 and the sliders 54 are threadedly connected. The two sliders 54 have opposite internal directions.

[0035] Specifically, the support mechanism 5 also includes contact plates 58. The first mounting plate 31 and the second mounting plate 32, facing away from each other, each abut against a contact plate 58. Each end of the contact plate 58 is provided with a limiting block 59. The slider 54 is rotatably connected to a connecting arm 55 facing the contact plate 58. A telescopic arm 56 is slidably connected inside the connecting arm 55. The telescopic arm 56 is rotatably connected to the contact plate 58. A buffer spring 57 abuts between the connecting arm 55 and the telescopic arm 56. Because the entire battery compartment 1 is very heavy, resulting in significant inertia, after placing the battery, tools are sequentially inserted into the interiors of different second drive blocks 53 to drive... The second lead screw 52 rotates, dragging the two sliders 54 to slide inside the second track groove 51. The sliders 54 drag the connecting arm 55, carrying the telescopic arm 56, to move, ultimately moving the contact plate 58. The contact plate 58 contacts and abuts against one side of the first mounting plate 31 or the second mounting plate 32, which reinforces the stability of the first mounting plate 31 and the second mounting plate 32. The buffer spring 57 abuts between the telescopic arm 56 and the connecting arm 55, which can compress the buffer spring 57 in advance to store energy, suppressing or slowing down the energy absorption of the battery's inertial micro-movement in the later stage, thus improving the stability of the battery.

[0036] In use, this invention first requires understanding the size of the battery pack based on the range requirements of new energy vehicles. Then, an external tool is inserted into the first drive block 47, and the tool is used to rotate the first drive block 47. The first drive block 47 drives the fourth bevel gear 46 to rotate, which in turn drives the first rotating shaft 43 to rotate by meshing with the third bevel gear 45. The first rotating shaft 43 rotates synchronously through the meshing of two second bevel gears 44 with the first bevel gears 42 at both ends. This causes the two first lead screws 41 to rotate synchronously. The internal threads of the first protrusion 34 and the second protrusion 35, connected to the same first rotating shaft 43, are in opposite directions, facilitating adjustment of the distance between the first protrusion 34 and the second protrusion 35. The first protrusion 34 moves the first mounting plate 31, and the second protrusion 35 moves the second mounting plate 32. After the first and second mounting plates 31 and 32 move, the space between them can be adjusted, allowing for easy adjustment of the installation space according to the number of batteries. After the batteries are placed, the first lead screw 41 rotates in the previous direction, driving the first and second mounting plates 31 and 32 to move closer together, thus shortening the gap with the batteries and securely clamping them. When replacing or adding new batteries later, the first and second mounting plates 31 and 32 can be loosened again to accommodate the new batteries. The battery design avoids the traditional one-time fixed battery operation, making subsequent maintenance and recycling more convenient. Different battery capacities can be replaced with the same mold according to different car requirements, avoiding frequent mold opening and reducing production costs. It also maintains the commonality between electromagnetic compartment parts, resulting in lower replacement costs later. A telescopic plate 33 is provided between the first mounting plate 31 and the second mounting plate 32. The telescopic plate 33 mainly serves to improve the stability of the sliding between the two, supplementing the sliding gap and suppressing loosening between the first mounting plate 31 and the second mounting plate 32. Due to the large weight of the entire battery compartment 1, the resulting inertia is extremely large. Therefore, after placing the battery, it is used sequentially... The tool is inserted into the interior of different second drive blocks 53, driving the second lead screw 52 to rotate. The second lead screw 52 drags two sliders 54 to slide inside the second track groove 51. The sliders 54 drag the connecting arm 55 to carry the telescopic arm 56 to move, and finally drive the contact plate 58 to move, so that the contact plate 58 contacts and abuts against one side of the first mounting plate 31 or the second mounting plate 32, which plays a role in stabilizing the first mounting plate 31 and the second mounting plate 32. There is a buffer spring 57 between the telescopic arm 56 and the connecting arm 55, which can compress the buffer spring 57 in advance to store energy, which plays a role in suppressing or slowing down the energy absorption of the battery position inertial micro-movement in the later stage, thereby improving the purpose of stabilizing the battery.The battery compartment 1 has an upper cover 21 at the top and a lower cover 22 at the bottom. Both the upper cover 21 and the lower cover 22 have multiple horizontal support pieces 25 and vertical support pieces 26 inside. These support pieces divide the cavity within the cover into multiple independent cavity slots 27. The cavity slots 27 are filled with air. This reduces the amount of material used in the cover, decreasing the overall weight and load of the vehicle, thus improving its range. It also increases the strength of the cover; even if the cover is punctured by a foreign object, the air inside one of the punctured cavity slots 27 escapes rapidly, offsetting the impact force. The kinetic energy of the foreign object decreases further with each cavity slot 27 it passes through. Furthermore, the cavity slots 27 are multi-layered, providing multi-layered protection. The upper cover 21 and the lower cover 22 have identical shapes and are common components.
