Description

Technical Field

[0001] The present invention relates to the technical field of vehicle battery transfer equipment, and in particular to a pushing device and a pushing method for installing a battery in a passenger car cabin. Background Art

[0002] New energy buses or coaches are vehicles that use a new power system and are mainly driven by new energy. Such vehicles usually have lower carbon emissions, higher energy efficiency, and lower noise levels, which are of great significance for improving air quality and reducing urban noise pollution. The core components of new energy buses include drive motors, electronic control systems, and power batteries, which are called the "three electrics" of electric vehicles.

[0003] In terms of power batteries, new energy buses mainly use lithium iron phosphate batteries and ternary lithium batteries. Lithium iron phosphate batteries have the advantages of high safety, good cycle performance, green environmental protection and low price. Ternary lithium batteries have higher energy density and large current discharge capacity, and are suitable for models with high requirements for acceleration and climbing performance. The energy density of lithium iron phosphate batteries is usually 175Wh / kg~185Wh / kg, and the energy density of ternary lithium batteries is usually 200Wh / kg; no matter which type of battery, the weight of a single battery is about 300kg, and the whole vehicle needs to be installed with 10~12 batteries.

[0004] In the prior art, the installation of batteries in new energy buses is all done manually. The batteries are first transported to the side of the cabin by a forklift, and then manually pushed into the cabin. However, since the batteries are heavy, manual pushing can easily cause uneven force on both sides, which can easily cause collision and interference between the battery edge and the cabin side, damaging the battery and causing air tightness problems in the battery pack. In addition, manual pushing is costly and can easily cause manual fatigue assembly, resulting in slow battery assembly, failure to meet the assembly cycle, and production line blockage.

[0044] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0045] like Figure 1 , Figure 2 As shown, the present invention provides a pushing device for installing batteries in a passenger car cabin, comprising: a lifting cart 100, a bracket 200, a pushing cylinder 300, a roller frame 400, a roller wheel 500, a pushing rod assembly 600 and a guide assembly 700;

[0046] A bracket 200 is provided at the top of the lifting cart 100, and a pushing cylinder 300 is provided on the top surface of the bracket 200. Roller frames 400 are fixed on both sides of the output end of the pushing cylinder 300 through the bracket 200. A number of rotatable rollers 500 are evenly spaced between the two roller frames 400. A pushing rod assembly 600 is provided on the outer side of the roller frame 400. The pushing rod assembly 600 is used to prevent the battery from deviating along the first direction a. Guide assemblies 700 are provided on both sides of the end of the bracket 200.

[0047] Specifically, the lifting trolley 100 is made of welded steel pipes. The lifting trolley 100 lifts the bracket 200 cut from a square pipe by installing a cylinder or a lifting device at the edge corner. The two can be connected by welding or bolts. The lifting trolley 100 can lift the bracket 200 to be flush with the passenger car door, so that the battery installation position in the up and down directions is more accurate; the top surface of the bracket 200 is fixedly connected with a pushing cylinder 300 by bolts, and the left and right sides of the pushing rod at the output end of the pushing cylinder 300 are fixed with roller frames 400 through the bracket 200. The roller frames 400 on both sides are penetrated by a plurality of rotatable rollers 500 through through holes. The battery is placed on the surface of the roller 500 to reduce friction. The pushing cylinder 300 contacts the side of the battery to push the battery into the passenger car cabin.

[0048] The outer side of the roller frame 400 is provided with an L-shaped push rod assembly 600 through a reinforcing rod. The push rod assembly 600 can clamp the left and right sides of the battery to prevent the battery from shaking during the movement of the lifting cart. For batteries of different sizes, the spacing between the push rod assemblies is adjusted to adapt to batteries of different sizes; the push rod assembly 600 is used to prevent the battery from shifting along the first direction a, which is perpendicular to the direction of the push cylinder 300, that is, the left or right side of the battery. Guide assemblies 700 are welded on both sides of the end of the bracket 200. When the battery is transported to the specified position and the push cylinder 300 is pushed, the battery contacts the surface guide wheel of the guide assembly 700 to provide guidance for the battery to enter the cabin.

[0049] It should be noted that the bracket 200 can be formed by fully welding a 40mm×40mm×3mm square tube.

[0050] It should be noted that a baffle with a rectangular cross-section may be fixedly connected to the top of the roller frame 400 to prevent the battery from shaking left and right during the movement of the lifting cart 100.

[0051] In an embodiment of the present invention, the lifting cart 100 includes a cart plate 101, universal wheels 102, a lifting cylinder 103, a support plate 104, a slide rail 105, a pulley 106, a lifting lug 107 and a reinforcing rod 108;

[0052] A universal wheel 102 is provided at the bottom end of the trolley plate 101, and a number of lifting cylinders 103 are evenly distributed on the top surface of the trolley plate 101. The top end of the push rod on the lifting cylinder 103 is fixedly connected to a support plate 104. A slide rail 105 is provided in the middle of the top of the trolley plate 101 in a direction parallel to the ground. Two pulleys 106 are slidably connected to the slide rail 105. A lifting ear 107 is provided at the bottom end of the support plate 104, and the pulley 106 is connected to the lifting ear 107 through a reinforcing rod 108; the top of the support plate 104 is fixedly connected to the bracket 200.

[0053] Specifically, a trolley handle welded with a steel pipe is welded on the side of one side of the trolley plate 101. The trolley plate 101 is rectangular in shape. The four corners of the bottom of the trolley plate 101 are provided with pulleys to realize the moving function of the lifting trolley 100; four lifting cylinders 103 with output ends facing upward are provided at the four corners of the top of the trolley plate 101, and the four lifting cylinders support the support plate 104. Two slide rails 105 parallel to the ground are welded in the middle of the trolley plate 101, and two pulleys 106 are slidably connected on each slide rail 105. The four pulleys 106 are connected to the four lifting ears 107 welded at the bottom of the support plate 104 through the reinforcing rod 108, in a cross shape, to play a supporting role. When the lifting trolley 100 transports the battery to the designated location, the lifting cylinder 103 lifts the support plate 104, and the distance between the two pulleys 106 gradually decreases, so that the reinforcing rod 108 plays an auxiliary supporting role for the support plate 104 from the middle.

[0054] In the embodiment of the present invention, the pushing cylinder 300 includes a cylinder body 301, a pushing plate 302 and a rubber pad 303;

[0055] The cylinder body 301 is fixed to the top of the bracket 200 by two parallel steel plates 800; the end of the push rod on the output end of the cylinder body 301 is fixedly connected with a push plate 302, and a rubber pad 303 is bonded to the surface of the push plate 302, and the rubber pad 303 is used to contact the battery surface.

[0056] The air inlet 304 and the air outlet 305 of the cylinder body 301 are both connected to the PA pipe; a pressure gauge 306 is installed on the cylinder body 301 .

[0057] Specifically, two vertical parallel steel plates 800 are welded to the top of the bracket 200, and the two steel plates 800 are fixed with the cylinder body 301 by external hexagonal bolts and flat washers. The output end of the cylinder body 301 is parallel to the ground, and the output end push rod of the cylinder body 301 is fixed with a rectangular or circular push plate 302, so as to be able to push the battery to move horizontally into the passenger car cabin; a rubber pad 303 is pasted on the surface of one end of the push plate 302 away from the cylinder body 301, and the rubber pad 303 is used to contact the battery surface. Due to its good elasticity, the rubber pad 303 can absorb and reduce the vibration generated by pushing the battery to work, thereby protecting the battery surface from wear and damage.

[0058] A barometer 306 is installed on the cylinder body 301 to detect changes in the air pressure in the cylinder. The air inlet 304 and the air outlet 305 of the cylinder body 301 are connected to the PA tube, and the reciprocating motion and forward movement distance of the push rod at the output end of the cylinder body 301 can be controlled by a switch.

[0059] In the embodiment of the present invention, a partition plate 401 is fixedly connected to the center position between the two roller frames 400 through the bracket 200 , and a plurality of rollers 500 are arranged in pairs through the partition plate 401 .

[0060] Specifically, since the transported bus battery body is large in size, the diameter and length of the rotatable roller 500 fixed by the two roller supports 400 need to be increased, which increases the cost. Figure 4 As shown, in this embodiment, a group of partition plates 401 are welded at the center position of the bracket 200, so that the rollers 500 are arranged in pairs through the partition plates 401, and a number of rollers 500 are changed from a single row to a double row. While ensuring that the batteries can be pushed smoothly, the length of a single roller 500 is reduced, and the installation of the roller 500 is also easy.

[0061] In the embodiment of the present invention, the push rod assembly 600 includes a cylinder support 601, a pneumatic push rod 602 and a push block 603;

[0062] The cross section of the cylinder bracket 601 is L-shaped. One end of the cylinder bracket 601 is fixed to the outside of the roller frame 400 through the bracket 200. The other end of the cylinder bracket 601 is provided with a pneumatic push rod 602. The push rod at the output end of the pneumatic push rod 602 is provided with a push block 603.

[0063] Specifically, Figure 3As shown, the cylinder bracket 601 is L-shaped, and the bottom end is fixed on the bracket 200 by an external hexagonal bolt. The cylinder brackets 601 are arranged in pairs, the number is at least not less than one pair and they are arranged oppositely. The end of the upward extension section of the cylinder bracket is fixedly connected with a pneumatic push rod 602, and the end of the output end of the activated pneumatic push rod 602 is fixedly connected with a rectangular push block 603. When the battery is placed on the roller 500, the pneumatic push rods 602 on both sides are activated, and the push blocks 603 extend and clamp the left and right sides of the battery, achieving the limitation of the first direction a, that is, the direction perpendicular to the push cylinder 300, to prevent the battery from being cheap during the movement, and can clamp batteries of different sizes.

[0064] In the embodiment of the present invention, the guide assembly 700 includes a guide bracket 701, a guide cylinder 702, a guide wheel frame 703 and a guide wheel 704;

[0065] The two guide brackets 701 are fixedly connected to the two sides of the bracket 200 respectively. A guide cylinder 702 is provided at the top of each guide bracket 701. A guide wheel frame 703 is provided on the pushing rod at the output end of the guide cylinder 702. A plurality of rotatable guide wheels 704 are evenly distributed on the guide wheel frame 703.

[0066] The surface of the guide wheel 704 is coated with polyurethane or rubber.

[0067] A baffle 900 is disposed at the middle of the end of the bracket 200 ; the baffle 900 is used to prevent the battery from deviating along the second direction b.

[0068] Specifically, Figure 2 , Figure 4 As shown, two guide brackets 701 are respectively fixed to the two sides of the end of the bracket 200 and are arranged oppositely. The guide bracket 701 is L-shaped. A guide cylinder 702 is provided at one end of the guide bracket 701 extending upward. A long guide wheel frame 703 is bolted to the push rod at the output end of the guide cylinder 702. A row of guide wheels 704 are distributed on the guide wheel frame 703. When the lifting trolley 100 moves to the passenger cabin door, the guide cylinder 702 is started, and the push rod is extended to drive the guide wheel frame 703 and the guide wheel 704 to retract to the middle and align with the passenger cabin. At this time, the push cylinder 300 pushes the battery forward, and the left and right surfaces of the battery contact the guide wheel 704. The battery is pushed into the passenger cabin through the sliding guidance of the guide wheel 704, and the precise push is completed to avoid collision with the outside of the passenger cabin and damage to the battery.

[0069] The surface of the guide wheel 704 is coated with polyurethane or rubber. Since the guide wheel 704 is in contact with the battery, there may be a slight deviation in the battery before it contacts the guide wheel. Therefore, coating with polyurethane or rubber can improve the wear resistance of the guide wheel 704, reduce friction, and increase the service life.

[0070] Specifically, the baffle 900 at the middle of the end of the bracket 200 can be bolted or hinged to the bracket 200 to prevent the battery from shifting along the second direction b, which is the pushing direction of the pushing cylinder 300, to prevent the battery from falling from the end of the bracket 200 during the movement of the lifting cart 100.

[0071] The present invention also provides a method for pushing a battery-mounted pushing device in a passenger car cabin, such as Figure 5 , Figure 6 As shown, the following steps are included:

[0072] Step 1: Lift the bus battery to the surface of the roller 500 by a mobile crane, and start the push rod assembly 600 to adjust the position of the bus battery for clamping;

[0073] Specifically, the universal wheel 102 on the lifting trolley 100 is locked, the bus battery is lifted to the surface of the roller 500 by a mobile crane, the push rod assemblies 600 on both sides are started to clamp according to the actual size of the battery, and the left and right limit of the battery is adjusted.

[0074] Step 2: Push the guide assembly 700 to the edge of the passenger car door by using the lifting trolley 100 and use the lifting trolley 100 to align the guide assembly 700 with the door;

[0075] Step 3, start the pushing cylinder 300 to move the bus battery on the surface of the roller 500 and push it; when the battery is pushed to the end, the bus battery contacts the guide assembly 700 and is installed in the bus door, completing the pushing.

[0076] Specifically, the push rod assembly 600 is retracted inward and the guide assembly 700 is opened so that the guide wheel frame 703 and the guide wheel 704 extended from the guide assembly 700 are flush with the passenger compartment, and the push cylinder 300 is started so that the passenger compartment battery is slowly moved and pushed on the surface of the roller 500 so that the battery contacts the guide wheel 704 and is guided into the compartment.

[0077] It should be noted that the push cylinder 300, the push rod assembly 600 and the guide assembly 700 can all be electrically connected to the controller to achieve remote operation of the push of the cylinder and realize automated push.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
