[0051] The present invention will be further described below in conjunction with the accompanying drawings.

[0052] See also Figures 1 to 3 As shown, a battery insulation device provided by the present application includes a containing component 100 and a snow removal component 200 .

[0053] When in use, the battery 500 can be placed in the first cavity formed inside the receiving assembly 100, and the receiving assembly 100 covering the battery 500 can protect the battery 500 and achieve the effect of heat insulation.

[0054] In snowy weather, the snow removal assembly 200 connected to the receiving assembly 100 can be used to scrape off the snow on the top of the receiving assembly 100 to prevent the snow from lowering the temperature of the receiving assembly 100. The heat preservation capacity of the battery heat preservation device in snowy weather is improved, so that the temperature of the battery 500 does not drop too quickly. Compared with only setting the heat preservation structure, the heat preservation capacity in snowy weather is further improved, and the working time of the battery 500 in snowy weather is extended, so that the grinding equipment provided with the battery heat preservation device can work longer in snowy weather.

[0055] The snow removal assembly 200 includes a driving mechanism 210 and a snow scraping unit 220, and the snow scraping unit 220 is located above the receiving assembly 100 and connected to the driving mechanism 210. The driving mechanism 210 connected to the receiving assembly 100 drives the snow scraping unit 220 above the receiving assembly 100 to move, so that the snow on the receiving assembly 100 is scraped off.

[0056] In some implementations, see Figures 2 to 4As shown, the receiving assembly 100 includes a box body 110 and a cover body 120, the cover body 120 is installed above the box body 110, and the cover body 120 and the box body 110 enclose a first cavity for receiving the battery 500. The cover body 120 is connected to a first support member 130, and a first slide groove 131 is provided on the first support member 130, and the snow scraping unit 220 is slidably installed in the first slide groove 131. The driving mechanism 210 is used to drive the snow scraping unit 220 to move along the extension direction of the first slide groove 131.

[0057] The first slide groove 131 provided on the first support member 130 limits the moving track of the snow scraping unit 220, so that the path is more stable when scraping snow, and reduces the interference of snow on the moving track of the snow scraping unit 220, so that the snow scraping unit 220 can more stably clean the snow on the receiving assembly 100.

[0058] In some implementations, see Figure 3 as well as Figure 4 As shown, the extension direction of the first slide groove 131 is parallel to the top surface of the cover body 120, and the snow scraper unit 220 includes a snow scraper rod 222, which contacts the top surface of the cover body 120 to generate heat by friction on the top surface of the cover body 120 when the snow scraper unit 220 scrapes snow.

[0059] That is, in the present application, the snow scraping rod 222 is used to scrape the snow on the top of the cover 120. Since the extension direction of the first chute 131 is parallel to the top surface of the cover 120, when the driving mechanism 210 drives the snow scraping unit 220 to move and scrape the snow, the distance between the snow scraping unit 220 and the top surface of the cover 120 can be kept unchanged. Since the snow scraping rod 222 is in contact with the top surface of the cover 120, that is, when the driving mechanism 210 drives the snow scraping unit 220 to move and scrape the snow, the snow scraping rod 222 can always keep in contact with the top surface of the cover 120. The snow scraping rod 222 can not only scrape the snow on the top surface of the cover 120 cleanly, but also can scrape the top surface of the cover 120 with the snow scraping rod 222 to achieve the effect of frictional heat generation, thereby increasing the temperature of the surface of the cover 120, thereby increasing the temperature of the battery 500 in the box 110.

[0060] See also Figure 3 As shown, a base 400 is installed at the bottom of the box body 110 .

[0061] See also Figure 1 , Figure 2 as well as Figure 5As shown, two covers 120 are installed on the top of the box 110, and each cover 120 is connected to a snow removal assembly 200. Each snow scraping unit 220 has two snow scraping rods 222 arranged in parallel. By providing two snow scraping rods 222, when the snow scraping unit 220 is moved once, two snow scraping rods 222 can be used to achieve two snow scraping actions on the cover 120, thereby improving the efficiency of snow scraping. It is understandable that the efficiency of snow scraping can be further improved by increasing the number of snow scraping rods 222 on the snow scraping unit 220.

[0062] In some implementations, the bottom surfaces of the two snow scraping rods 222 are in contact with the top surface of the cover 120, so that the two snow scraping rods 222 can generate heat by friction with the top surface of the cover 120, thereby improving the efficiency of frictional heat generation. In other implementations, the bottom surface of one of the two snow scraping rods 222 can be in contact with the top surface of the cover 120, and the top surface of the other snow scraping rod 222 can be slightly higher than the top surface of the cover 120, thereby achieving the effect of layered snow scraping. The high snow scraping rod 222 is used to scrape off the snow on the upper layer, while the low snow scraping rod 222 is used to scrape off the snow on the lower layer. In this way, the amount of snow scraped by a single snow scraping rod 222 is reduced, and the bending or breaking of the snow scraping rod 222 caused by excessive snow scraping is avoided.

[0063] See also Figure 5 As shown, in some implementations, the snow scraper rod 222 has a snow guide surface 2221 that is inclined relative to the vertical surface. Therefore, during the snow scraping process, the inclined surface is used to guide the snow to lift the snow upward, which can achieve smoother snow scraping and reduce the difficulty of snow scraping compared to the vertically arranged snow scraper rod 222.

[0064] In some implementations, the inclination directions of the snow-guiding surfaces 2221 of the two snow-scraping rods 222 are opposite, so that when the snow-scraping rod 222 moves in one direction to scrape snow, the snow-guiding surface 2221 of one of the snow-scraping rods 222 can be used to guide the accumulated snow out, and when the snow-scraping rod 222 moves in another direction to scrape snow, the snow-guiding surface 2221 of the other snow-scraping rod 222 can be used to guide the accumulated snow out.

[0065] See also Figure 5 , Figure 6 as well as Figure 7 As shown, the snow scraping unit 220 includes a first rack 221, the first rack 221 includes a positioning block inserted into the first slide groove 131, and a second rack 133 is installed on the first support member 130. The first rack 221 and the second rack 133 are arranged in parallel.

[0066] The driving mechanism 210 includes a driving member 211 installed on the first support member 130, the driving shaft of the driving member 211 is connected to the first connecting rod 212, the end of the first connecting rod 212 away from the driving member 211 is rotatably connected to the second connecting rod 213, the second connecting rod 213 is rotatably connected to the driving gear 214, one side of the driving gear 214 is meshed with the first rack 221, and the other side of the driving gear 214 is meshed with the second rack 133.

[0067] That is, in the present application, the driving member 211, the first connecting rod 212 and the second connecting rod 213 are used to drive the driving gear 214, and the first rack 221 and the second rack 133 are arranged in parallel to limit the moving track of the driving gear 214, so that the driving gear 214 moves linearly along the extending direction of the first rack 221. Since the driving gear 214 is meshed with the second rack 133, the driving gear 214 can rotate relative to the axis of the driving gear 214 under the restriction of the second rack 133 when moving linearly. When the driving gear 214 rotates, it can drive the first rack 221 to move.

[0068] Since the driving gear 214 moves in a straight line under the restriction of the first rack 221 and the second rack 133, it can drive the first rack 221 meshing therewith to move in a straight line along the extension direction of the first slide groove 131, and the first rack 221 can be further driven to move in a straight line under the rotation of the driving gear 214. Compared with the fixed driving gear 214 driving the first rack 221 to move in a straight line, the movement displacement of the first rack 221 is expanded, thereby expanding the snow scraping range of the snow scraping unit 220, improving the insulation effect of the battery insulation device, and allowing the battery insulation device to be used for a long time in snowy weather.

[0069] See also Figure 8 As shown, in some implementations, a second slide groove 132 is provided on the first support member 130, and the second slide groove 132 is parallel to the first slide groove 131. The driving gear 214 includes a positioning protrusion inserted into the second slide groove 132. The linear movement trajectory of the driving gear 214 can be further limited by the cooperation between the second slide groove 132 and the positioning protrusion.

[0070] In some implementations, the length of the second connecting rod 213 is greater than the length of the first connecting rod 212, so that the first connecting rod 212, the second connecting rod 213 and the driving gear 214 form a crank slider mechanism. Compared with setting the first connecting rod 212 to be greater than the second connecting rod 213 so that the first connecting rod 212, the second connecting rod 213 and the driving gear 214 form a swing arm slider mechanism, the crank slider mechanism can drive the driving gear 214 to achieve reciprocating linear movement by the first connecting rod 212 rotating multiple times, so that the snow removal unit can achieve reciprocating linear movement to complete the snow removal on the top of the cover body 120. Compared with the swing arm slider mechanism that drives the driving gear 214 to reciprocate linear movement by swinging the first connecting rod 212, a unidirectional rotating driving member 211 can be used, so that a low-cost brushless motor can be used as the driving member 211, and a stepping motor does not need to be selected, which reduces the cost of the driving mechanism 210.

[0071] See also Fig. 9 as well as Fig.10 As shown, in some implementations, the containing assembly 100 includes a box body 110 and a cover body 120, the box body 110 is provided with an opening at the top, the cover body 120 is installed at the opening, a support plate 140 is installed inside the box body 110, the support plate 140 is used to carry the battery 500, the support plate 140 is connected to a lifting mechanism 300, the lifting mechanism 300 is connected to the cover body 120, and the lifting mechanism 300 is constructed to raise the support plate 140 when the cover body 120 opens the opening, and lower the support plate 140 when the cover body 120 closes the opening.

[0072] That is to say, in the present application, the support plate 140 can be raised and lowered by the switch of the cover 120, thereby raising or lowering the battery 500. When it is necessary to put the battery 500 into the box 110, or to take the battery 500 out of the box 110, the support plate 140 can be raised by the lifting mechanism 300 during the process of opening the cover 120, so that the support plate 140 is closer to the opening of the box 110, and the battery 500 can be conveniently put in and taken out. And when it is not necessary to put in or take out the battery 500, the cover 120 can close the opening to achieve the closure of the box 110, and the support plate 140 can be moved down. The closed box 110 reduces the heat exchange between the battery 500 and the outside world, slows down the temperature decay rate of the battery 500, and at the same time, the battery 500 can be moved down to make the battery 500 farther away from the cover plate, so as to prevent the low-temperature cover plate from taking away the heat of the battery 500, and further improve the insulation effect of the battery insulation device.

[0073] In some implementations, the lifting and lowering of the support plate 140 is achieved through a connecting rod mechanism in the present application. In other implementations, the lifting and lowering of the support plate 140 can also be achieved through structures such as motors and hydraulic levers.

[0074] See also Figures 9 to 14 As shown, in some implementations, the support plate 140 is slidably installed inside the box body 110, and the sliding direction of the support plate 140 is along the vertical direction. The lifting mechanism 300 includes a first rotating member 310, and the first rotating member 310 includes a third connecting rod 311 and a fourth connecting rod 312. The third connecting rod 311 is fixedly connected to the fourth connecting rod 312, wherein one end of the third connecting rod 311 is rotatably connected to the side panel of the box body 110, and the other end of the third connecting rod 311 is rotatably connected to the cover body 120.

[0075] See also Fig.13 as well as Fig.14 As shown, one end of the fourth connecting rod 312 is fixedly connected to the third connecting rod 311, and the other end of the fourth connecting rod 312 is rotatably connected to the fifth connecting rod 320, and the end of the fifth connecting rod 320 away from the fourth connecting rod 312 is rotatably connected to the support plate 140, wherein the fourth connecting rod 312, the fifth connecting rod 320 and the support plate 140 constitute a crank slider mechanism to realize the lifting movement of the support plate 140.

[0076] When the cover 120 is rotated to open, the third connecting rod 311 rotates synchronously with the rotation of the cover 120, and drives the fourth connecting rod 312 fixedly connected thereto to rotate around one end of the third connecting rod 311 connected to the side plate of the box body 110. During the rotation of the fourth connecting rod 312, the fifth connecting rod 320 rotatably connected thereto is driven to rotate and the support plate 140 is driven to move vertically along the box body 110, thereby completing the lifting of the support plate 140.

[0077] When the cover 120 is rotated to close, the first rotating member 310 rotates to drive the fifth connecting rod 320 and the supporting plate 140 to move downward, thereby completing the descent of the battery 500 .

[0078] Compared with setting up an additional driving device to drive the support plate 140 to rise and fall, the present application realizes the linkage between the support plate 140 and the cover body 120 through the first rotating member 310 and the fifth connecting rod 320, thereby reducing the energy consumption during the lifting and falling.

[0079] See also Fig.13 As shown, in some implementations, the lifting mechanism 300 also includes a sixth link 330, one end of the sixth link 330 is rotatably connected to the side wall of the box body 110, and the other end of the sixth link 330 is rotatably connected to the cover body 120, wherein the length of the sixth link 330 is equal to the length of the third link 311, and the sixth link 330, the box body 110, the third link 311 and the cover body 120 constitute a parallelogram linkage mechanism.

[0080] That is, when the cover 120 is opened, not only the third connecting rod 311 but also the sixth connecting rod 330 will be driven to rotate. Since the sixth connecting rod 330, the box 110, the third connecting rod 311 and the cover 120 form a parallelogram connecting rod mechanism, when the cover 120 is opened, the extension direction of the cover 120 will always remain in the state when the opening is closed (horizontally extended in the figure), maintaining the opening posture of the cover 120, preventing objects on the cover 120 from sliding into the box 110 and damaging the battery 500 in the box 110 due to the change in the angle of the cover 120 during the opening process, thereby improving the safety when opening and closing the cover.

[0081] In some implementations, two covers 120 are mounted on the box 110, and each of the covers 120 is connected to a corresponding lifting mechanism 300, and the first rotating member 310 further includes a semicircular gear, and the semicircular gears 313 of the two lifting mechanisms 300 are meshed. That is, after one cover 120 is moved out of the top of the opening, the semicircular gear corresponding to it can be driven to rotate, and because the two semicircular gears 313 are meshed, the cover 120 that is actively opened can rotate the other cover 120 in the opposite direction through the meshing cooperation of the semicircular gears 313, thereby realizing the relative expansion of the two covers 120, completing the relative separation of the covers 120 and the opening of the box 110. Among them, the transmission ratio of the two semicircular gears 313 can be 1:1, so that the rotation angles of the two semicircular gears are the same. In other implementations, the transmission ratio of the two semicircular gears can also be set to other transmission ratios, so that the opening speeds of the two covers 120 are different.

[0082] See also Fig.11 as well as Fig.12 As shown, in some implementations, the power supply circuit of the driving mechanism 210 includes a first branch and a second branch, the containing assembly 100 includes a box body 110 and two covers 120, the two covers 120 can be relatively installed on the top of the box body 110, and the first branch is set in one of the covers 120, and the second branch is set in the other cover 120. When the two covers 120 are tightly attached to close the opening of the box body 110, the first branch is connected to the second branch, so that the power supply circuit of the driving mechanism 210 When the two covers 120 are separated and the opening of the box body 110 is opened, the first branch is disconnected from the second branch, so that the power supply circuit of the driving mechanism 210 is broken, so that the driving mechanism 210 is prevented from driving the snow scraper unit 220 to move when the cover body 120 is opened, thereby avoiding scratches on the human body due to the movement of the snow scraper unit 220 and improving the safety when storing and accessing the battery 500 in the box body 110.

[0083] In addition to realizing on-off control of the power supply circuit by opening and closing the box 110, a control device can also be set between the power supply circuit and the driving member 211 to control the start and stop and operating status of the snow scraping unit 220 when the power supply circuit is energized.

[0084] See also Fig.11 as well as Fig.12 As shown, in some implementations, one of the covers 120 is provided with a plug interface 122, and the first branch is electrically connected to the plug interface 122, and the other cover 120 is provided with a plug connector 121, and the second branch is electrically connected to the plug connector 121. When the two covers 120 are pressed against each other, the plug connector 121 is inserted into the plug interface 122 of the other cover 120, and the plug connector 121 is electrically connected to the plug interface 122, thereby realizing the electrical connection between the first branch and the second branch.

[0085] In a second aspect, an embodiment of the present invention further provides a grinding device, which includes a grinding mechanism and the above-mentioned battery heat preservation device, wherein the battery heat preservation device contains a battery 500, and the battery 500 is electrically connected to the grinding mechanism.
