Description

Technical Field

[0001] The utility model belongs to the technical field of battery replacement equipment, and specifically relates to a position adjustment device for a battery replacement device of a new energy commercial vehicle. Background Art

[0002] With the development of the electric vehicle industry, the battery capacity of electric vehicles has become a bottleneck in its development. In order to continuously provide continuous power for electric vehicles and overcome the disadvantage of long charging time, the method of battery replacement is used to provide continuous power for electric vehicles.

[0003] New energy commercial vehicles, such as logistics vehicles and light trucks, often use a mid-mounted battery (the battery is located in the middle of the chassis). Battery swapping is achieved by using a battery swapping device at the rear end to push and pull the battery, meaning the battery is pulled outward when removed and pushed in when inserted.

[0004] Prior art patents such as CN115158246A disclose push-pull battery swap stations suitable for new energy commercial vehicles. These systems present at least the following technical issues: While the battery swap station utilizes centering, lifting, and leveling mechanisms to achieve docking between the vehicle's battery compartment and the battery swap mechanism, the battery's height and angle cannot be adjusted when docking the swap unit with the battery compartment or stacking mechanism, impacting docking. Furthermore, during the battery swap process, as the battery is pulled in or out of the new energy commercial vehicle, the vehicle's weight changes, affecting the vehicle's height. This significantly complicates the battery swapping process. Summary of the Invention

[0005] The problem to be solved by the present invention is to provide a position adjustment device, which can adjust the height and angle of the battery swap device, and can adjust the position of the battery swap device so that it can be accurately docked with the battery compartment in the new energy commercial vehicle or the battery storage rack, and can adjust the height and angle of the new energy commercial vehicle in the process of battery swapping, which causes the vehicle body to rise or fall due to the change in its own weight caused by the battery of the new energy commercial vehicle being pulled out or pushed in.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a position adjustment device for a battery exchange device of a new energy commercial vehicle, which is used to adjust the position of the battery exchange device. The key is: the position adjustment device includes two groups of position adjustment components symmetrically arranged on both sides of the width direction of the battery exchange device, and each group of position adjustment components includes a first lifting drive component and a second lifting drive component which are arranged in sequence along the length direction of one side of the battery exchange device and the execution ends are movably connected to the battery exchange bracket in the battery exchange device.

[0007] Furthermore, the first lifting drive component and the second lifting drive component both include a rigid chain, a chain storage box for storing the rigid chain, a driving gear and a matching gear drive motor arranged on the chain storage box and driving the rigid chain to move, and the battery exchange bracket is located below the driving end of the rigid chain and is movably connected to the driving end.

[0008] Furthermore, a connecting bracket is provided between the two chain storage boxes in the same group of position adjustment components.

[0009] Furthermore, a first movable connection component is provided between the execution end of the first lifting drive component and the battery exchange bracket, and the first movable connection component includes a first fixed seat hinged on the battery exchange bracket, a second fixed seat fixed to the execution end of the first lifting drive component, and a connecting rod hinged to the first fixed seat and the second fixed seat respectively.

[0010] Furthermore, a second movable connection component is provided between the execution end of the second lifting drive component and the battery exchange bracket, and the second movable connection component includes a first connecting seat hinged to the battery exchange bracket, a second connecting seat fixed to the execution end of the second lifting drive component, a first articulated seat hinged to the first connecting seat, and a second articulated seat with both ends hinged to the first articulated seat and the second connecting seat respectively.

[0011] Furthermore, a two-way movable connection component is provided between the execution end of the first lifting drive component and the battery exchange bracket, and between the execution end of the second lifting drive component and the battery exchange bracket. The two-way movable connection component includes a first limit block fixed on the battery exchange bracket, a second limit block fixed on the execution end of the first lifting drive component or the execution end of the second lifting drive component, a limit rod with two ends passing through the first limit block and the second limit block respectively, a first spherical crown movable block mounted on the end of the limit rod and located in the limiting cavity of the first limit block, a first nut threadedly connected to the limit rod and limiting the first spherical crown movable block on the limit rod, a second spherical crown movable block mounted on the end of the limit rod and located in the limiting cavity of the second limit block, and a second nut threadedly connected to the limit rod and limiting the second spherical crown movable block on the limit rod.

[0012] Furthermore, a pad that matches the first spherical crown movable block or the second spherical crown movable block is provided in the limiting cavity of the first limiting block and the limiting cavity of the second limiting block.

[0013] Furthermore, the position adjustment device also includes a bottom connecting frame and a top connecting frame respectively connecting the bottom and top of the two groups of position adjustment components.

[0014] Furthermore, the top or bottom of the position adjustment device is limited on the track, and a translation drive component for driving the battery exchange bracket to move along the track is provided between the top connecting frame and the track or between the bottom connecting frame and the track.

[0015] Furthermore, the battery exchange device includes a battery exchange bracket having at least one battery storage position and a battery push-pull device arranged on the battery exchange bracket and equipped for each battery storage position.

By adjusting the height of the four positions of the battery exchange bracket in the battery exchange device and adjusting the angle within a certain range, the battery exchange device can be accurately docked with the battery compartment on the new energy commercial vehicle or the battery storage rack, which is convenient for pushing and pulling the battery; 2. The height and angle are adjusted for the situation where the new energy commercial vehicle's own weight changes due to the battery being pulled out or pushed in during the battery exchange process, causing the vehicle body to rise or fall; 3. The use of an active connection between the battery exchange bracket and the position adjustment device facilitates ensuring that the battery exchange bracket and the battery can naturally maintain a horizontal state under the action of their own gravity, thereby ensuring the stability of the pushing and pulling process.

DETAILED DESCRIPTION

[0025] See attached Figure 1 and 5 The utility model provides a position adjustment device for a battery exchange device of a new energy commercial vehicle, which is used to adjust the position of the battery exchange device.

[0026] See attached Figure 1 and 5 The above-mentioned battery exchange device includes a battery exchange bracket 1 having at least one battery storage position and a battery push-pull device 2 arranged on the battery exchange bracket 1 and equipped for each battery storage position.

[0027] When there is only one battery storage position on the battery exchange bracket 1, the position adjustment device can be used to realize the functions of battery stacking or battery exchange.

[0028] When used to swap batteries with vehicles and battery storage compartments, the battery swap bracket 1 is provided with two battery storage positions, each of which is equipped with a battery push-pull device 2. During battery swapping, one position is empty to pull the battery in the commercial vehicle into the storage position, while the other is used to store a fully charged battery to be pushed into the battery compartment of the commercial vehicle; when replacing a fully charged battery with the battery storage rack, one position is empty to pull the fully charged battery in the battery rack into the storage position, while the other is used to temporarily store the depleted battery of the commercial vehicle so that the depleted battery can be pushed into the battery compartment rack for charging.

[0029] The above-mentioned position adjustment device includes two groups of position adjustment components respectively arranged on both sides of the width direction of the battery swap bracket 1. Each group of position adjustment components includes a first lifting drive component and a second lifting drive component which are sequentially arranged along the length direction of one side of the battery swap bracket 1 and the execution ends are movably connected to the battery swap bracket 1. The four lifting drive components act synchronously to drive the overall lifting and lowering of the position of the battery swap bracket 1 in the height direction; the action of one or more lifting drive components can realize the fine adjustment of the position of the battery swap bracket 1 such as forward and backward pitch, left and right deflection when swapping batteries or placing batteries in the battery storage rack to align with the battery compartment of the new energy commercial vehicle or the battery compartment of the battery storage rack.

[0030] The first and second lifting drive components each include a rigid chain, a chain storage box 3 for storing the rigid chain, a drive gear mounted on the chain storage box 3 and driving the rigid chain, and a matching gear drive motor 4. The battery exchange bracket 1 is located below the drive end of the rigid chain and is movably connected to the drive end. The use of a rigid chain drive takes advantage of the rigid chain's strong load-bearing characteristics and also allows the rigid chain storage box 3 to serve as the pillar of the entire adjustment device, reducing the number of components. The lifting drive components can also utilize a motor-driven gear rack structure, electric cylinder, chain, or other device capable of linear drive. A connecting bracket 5 is provided between the two chain storage boxes 3 in the same position adjustment assembly to facilitate the connection and positioning between them. The position adjustment device also includes a bottom connecting frame 6 and a top connecting frame 7, which respectively connect the bottom and top of the two position adjustment assemblies. These two frames connect the four lifting drive components to form an integrated structure. Specifically, the two frames are connected to the upper and lower ends of the chain storage box 3.

[0031] To achieve a movable connection between the lifting drive component and the battery replacement bracket 1.

[0032] Example 1: See attached Figure 1-3 In this embodiment, a first movable connection component is provided between the execution end of the first lifting drive component and the battery swap bracket 1. A second movable connection component is provided between the execution end of the second lifting drive component and the battery swap bracket 1. The first lifting drive component is close to the entrance and exit of the battery in the battery swap bracket 1.

[0033] The first movable connection assembly includes a first fixed seat 8 hinged on the battery exchange bracket 1, a second fixed seat 9 fixed on the execution end of the first lifting drive component, and a connecting rod 10 hinged to the first fixed seat 8 and the second fixed seat 9 respectively.

[0034] The second movable connection component includes a first connecting seat 11 hinged to the battery exchange bracket 1, a second connecting seat 12 fixed to the execution end of the second lifting drive component, a first articulated seat 13 hinged to the first connecting seat 11, and a second articulated seat 14 whose two ends are respectively hinged to the first articulated seat 13 and the second connecting seat 12.

[0035] The structures of the two connecting components are different. This design not only allows the battery swap bracket 1 to be raised and lowered and swung left and right, and pitched forward and backward within a preset angle range under the drive of the lifting drive component, so that the temporary storage position of the battery on the battery swap bracket 1 is aligned with the commercial vehicle or battery compartment; it also reduces the relative position movement between the battery swap bracket 1 and the lifting drive component when the battery enters the battery swap bracket 1, so that the process of the battery entering and exiting the battery swap bracket 1 is stable.

[0036] Example 2: See attached Figure 5 and 6In this embodiment, a two-way movable connection assembly is provided between the execution end of the first lifting drive component and the battery swap bracket 1, and between the execution end of the second lifting drive component and the battery swap bracket 1. The two-way movable connection assembly includes a first limit block 15 fixed on the battery swap bracket 1, a second limit block 16 fixed at the execution end of the first lifting drive component or the execution end of the second lifting drive component, a limit rod 17 with both ends passing through the first limit block 15 and the second limit block 16 respectively, a first spherical cap movable block 18 sleeved on the end of the limit rod 17 and located in the limiting cavity of the first limit block 15, a first nut 20 threadedly connected to the limit rod 17 and limiting the first spherical cap movable block 18 on the limit rod 17, a second spherical cap movable block 19 sleeved on the end of the limit rod 17 and located in the limiting cavity of the second limit block 16, and a second nut 21 threadedly connected to the limit rod 17 and limiting the second spherical cap movable block 19 on the limit rod 17.

[0037] The limiting cavity of the first limiting block 15 and the limiting cavity of the second limiting block 16 are both provided with a pad 22 that matches the first spherical crown movable block 18 or the second spherical crown movable block 19. The pad 22 is limited in the cavity by a retaining ring through the hole.

[0038] In this embodiment, a four-link structure is formed between the battery swap bracket 1 and the two limit rods 17 in each position adjustment assembly and the lifting drive components, and the connections are all in a ball hinge structure that can rotate within a certain range. The battery swap bracket 1 is driven by the four lifting drive components to achieve the lifting and lowering within the height range and the left and right swing, front and back pitch within the preset angle range, so that the temporary storage position of the battery on the battery swap bracket 1 is aligned with the commercial vehicle or battery compartment. Compared with the first embodiment, this embodiment requires fewer parts to be designed and manufactured and is easy to manufacture.

[0039] See attached Figure 1 and 4 The top or bottom of the position adjustment device is limited on the track 23, and a translation drive component is provided between the top connecting frame 7 and the track 23 or between the bottom connecting frame 6 and the track 23 to drive the battery exchange bracket 1 to move along the track 23 to realize the reciprocating movement of the battery exchange bracket 1 between the new energy commercial vehicle and the battery storage rack.

[0040] When the track 23 is mated with the top connecting frame 7, it is connected to the ground via a mounting bracket 27. This structure allows the entire device to be suspended above the ground after installation. A guide assembly, primarily consisting of a slide rail and a slider, is located between the top connecting frame 7 and the track 23 to ensure stability during movement. The translation drive assembly includes a rack 24 fixed to the track 23, a gear 25 meshing with the rack 24, and a translation drive motor 26 fixed to the top connecting frame 7 and connected to the gear 25. Alternatively, the translation drive assembly can be a motor-driven running wheel that travels on the track 23, a motor-driven chain structure, or other similar structures.

[0041] When the track 23 is matched with the bottom connecting frame 6, the track 23 is arranged on the ground or in a groove opened in the ground, so that the entire device is supported on the ground after installation. The translation of the entire device is achieved by the running wheels set on the bottom connecting frame 6 and constrained on the track 23 and the matching running drive motor.

[0042] When the device of the utility model is specifically implemented: Figure 4 As shown, a battery storage rack and a battery swapping channel are located on either side of the positioning device. Initially, the battery swapping device is located on the battery access side of the battery storage rack to facilitate the entry of new energy commercial vehicles awaiting battery swapping. One temporary battery storage location on the battery swapping device contains a fully charged battery, while the other is empty. When the commercial vehicle reaches a designated area within the channel, the front and rear wheel centering devices position the front and rear wheels for subsequent battery swapping.

[0043] When replacing the battery, the translation drive motor 26 will drive the battery replacement device and the position adjustment device to move to the rear of the new energy commercial vehicle. The two sets of position adjustment components will simultaneously adjust the height and angle of the battery replacement device so that the temporary battery storage position without a battery is flush with the bottom of the battery compartment of the quasi-commercial vehicle. The matching battery push-pull device 2 will pull the commercial vehicle battery into the current temporary battery storage position; then, adjust the height of the battery replacement device up or down so that the fully charged battery is aligned with the battery compartment of the commercial vehicle, and the matching battery push-pull device 2 will push the fully charged battery into the battery compartment of the commercial vehicle, thereby completing the battery replacement.

[0044] During the battery swapping process, the weight of the new energy commercial vehicle changes due to the battery being pulled out or pushed in, causing the vehicle body to rise or fall. The two sets of position adjustment components can adjust the height and / or angle of the battery swapping device to ensure smooth battery swapping.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for protection of the utility model.
