Detailed Embodiments

[0036] In order to make the objectives, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] It should be noted that unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0038] In the related art, sightseeing vehicles in scenic spots are often in an overloaded operation stage and need to be in a long-term running state. However, due to the space limitation of the installation compartment, some vehicle models cannot meet the requirement of continuous operation, so the battery needs to be disassembled for charging. However, the ordinary battery replacement scheme requires removing four fixing bolts, removing the total positive and total negative cables of the lithium battery, removing the charging cable, removing the communication cable, taking out the battery, and then reinstalling it, which is rather cumbersome.

[0039] In order to improve the battery replacement efficiency of the vehicle, the embodiments of this application provide a power supply device and a vehicle. The power supply device may include: a battery body, including a first fixing structure; a loading rack, including a loading platform and a plurality of sliding mechanisms. The loading platform is provided with a second fixing structure, which cooperates with the first fixing structure to lock when the battery body is loaded on the loading platform. The plurality of sliding mechanisms are installed on the outer edge of the loading rack based on the same preset loading guide. Since the loading rack is provided with a plurality of sliding mechanisms and the battery body can be loaded on the battery body, the battery body can be installed in the installation compartment or removed from the installation compartment through the loading rack. Moreover, the outer edge of the loading rack is provided with a plurality of sliding mechanisms installed based on the same preset loading guide. In this way, the loading rack has a certain sliding ability. Therefore, during the battery replacement process, the power supply device can be slid into and out of the installation compartment through the sliding mechanisms of the loading rack, so that the battery can be replaced without disassembling and installing the fixing bolts, which is beneficial to improving the battery replacement efficiency and reducing the replacement difficulty. In addition, since there is no need to disassemble and install the fixing bolts, the situation of loose tooth caused by multiple disassembly and installation of the screws, which leads to insecure fixation of the battery body, can be reduced, which is beneficial to improving the power supply stability of the power supply device.

[0040] See Figure 1 and Figures 2A to 2C , Figure 1 shows the structure of the battery body provided by an embodiment of this application. Figures 2A to 2C shows the three-view structure of the loading rack provided by an embodiment of this application. In the embodiments of this application, the power supply device includes a battery body 100 and a loading rack 200.

[0041] The battery body 100 may include a first fixing structure 101. The loading rack 200 may include a loading platform 201 and a plurality of sliding mechanisms 202. The loading platform 201 is provided with a second fixing structure 203. The second fixing structure 203 can cooperate with the first fixing structure 101 to lock when the loading platform 201 loads the battery body 100. The plurality of sliding mechanisms 202 are installed on the outer edge of the loading rack 200 based on the same preset loading guide.

[0042] In one embodiment, the first fixing structure 101 may be a fixture, a mounting rack with through holes, etc., which is not specifically limited here. Among them, the first fixing structure 101 is distributed on at least one opposite side of the outer edge of the battery body 100. Here, the outer edge of the battery body 100 refers to the outer part of the battery body, such as the outer shell, the exposed frame, etc., which is not specifically limited here.

[0043] In one embodiment, the second fixing structure 203 corresponds to the first fixing structure 101 and may be a fixture, an installation through hole provided in the loading platform, etc., which is not specifically limited here. Among them, corresponding to the first fixing structure 101, the second fixing structure 203 is distributed on at least one opposite side of the inside of the loading platform 201.

[0044] In one embodiment, when the second fixing structure 203 cooperates with the first fixing structure 101 to lock when the loading platform 201 loads the battery body 100, it means that after the battery body 100 is arranged on the loading platform 201, the first fixing structure 101 and the second fixing structure 203 are correspondingly aligned and locked. Among them, when both the first fixing structure 101 and the second fixing structure 203 are fixtures, the first fixing structure 101 and the second fixing structure 203 can clamp each other; when the first fixing structure 101 is a mounting rack with through holes and the second fixing structure 203 is an installation through hole provided in the loading platform 201, the first fixing structure 101 and the second fixing structure 203 can be cooperatively locked through fixing components (such as bolts and nuts).

[0045] In one embodiment, the sliding mechanism 202 may be a pulley, a bearing, a sliding column, etc., which is determined according to the internal setting of the installation compartment of the vehicle. Here, the installation compartment refers to the structure of the vehicle for installing the power supply device. For example, assuming that there is a guide rail with the same sliding direction as the preset loading guide inside the installation compartment, the sliding mechanism 202 may be a sliding column, and the power supply device can slide along the guide rail through the sliding column, so as to complete the disassembly and assembly of the power supply device; for another example, assuming that there is no guide rail inside the installation compartment, the sliding mechanism 202 may be a pulley, and the power supply device can slide inside the installation compartment through the pulley to complete the disassembly and assembly of the power supply device, and so on, which is not specifically limited here.

[0046] In one embodiment, the preset loading orientation refers to the sliding direction in which the power supply device is loaded into the vehicle during the overall loading process of the power supply device into the vehicle. Specifically, since the loading rack 200 is provided with a sliding mechanism 202, the power supply device can be relatively easily installed into the installation bin by sliding. Similarly, when it is necessary to remove the power supply device from the vehicle, the power supply device can also be removed by sliding in the opposite direction of the preset loading orientation.

[0047] In one embodiment, the multiple sliding mechanisms 202 are installed on the outer edge of the loading rack 200 based on the same preset loading orientation, which means the installation method of installing the multiple sliding mechanisms 202 on the outer edge of the loading rack 200 in a way that enables the power supply device to slide along the preset loading orientation. For example, assuming the loading rack 200 is a cuboid and the preset loading orientation is the direction parallel to the long side of the cuboid, and the sliding mechanism 202 is a sliding column, then each sliding mechanism 202 is installed on the outer edge of the loading rack 200 in the direction perpendicular to the side where the column center is parallel to the long side. Here, the outer edge of the loading rack 200 refers to the outer part of the loading rack 200, such as the outer shell (such as a box-type loading rack), the frame (such as a frame-type loading rack), etc., which is not specifically limited here. In addition, when the multiple sliding mechanisms 202 are installed on the outer edge of the loading rack 200, the multiple sliding mechanisms 202 can be specifically installed on the side, bottom, etc. of the loading rack 200, which is not specifically limited here. In addition, when the multiple sliding mechanisms 202 are installed on the outer edge of the loading rack 200, the multiple sliding mechanisms 202 can be evenly distributed (for example, there are multiple outer sides of the loading rack 200 where the sliding mechanisms 202 are installed, and the number of sliding mechanisms 202 on each outer side is the same), or can be unevenly distributed (for example, there are multiple outer sides of the loading rack 200 where the sliding mechanisms 202 are installed, and the number of sliding mechanisms 202 on each outer side is different), which is not specifically limited here.

[0048] In one embodiment, the loading rack 200 may include a loading outer frame 204 and multiple loading rods 205. The multiple loading rods 205 are arranged inside the loading outer frame 204, and among them, multiple sliding mechanisms 202 are provided on the outer edge of at least one of the loading outer frame 204 and the multiple loading rods 205.

[0049] In one embodiment, the position where the loading outer frame 204 is provided with the second fixing structure 203 is matched with the fixing position of the first fixing structure 101. For example, if the first fixing structure 101 is provided on the short side of the battery body 100, then the loading outer frame 204 is provided with the second fixing structure 203 at the position on its own short side that bears the battery body 100; or if the first fixing structure 101 is provided on the long side of the battery body 100, then the loading outer frame 204 is provided with the second fixing structure 203 at the position on its own long side that bears the battery body 100, and so on, which is not specifically limited here.

[0050] In one embodiment, a plurality of sliding mechanisms 202 are provided on the outer edges of both the loading outer frame 204 and the plurality of loading rods 205. The number of sliding mechanisms 202 provided on the loading outer frame 204 may be the same as or different from the number of sliding mechanisms 202 provided on the plurality of loading rods 205, and no specific limitation is made here.

[0051] In one embodiment, a plurality of sliding mechanisms 202 are provided on the outer edges of both the loading outer frame 204 and the plurality of loading rods 205. The positions of the sliding mechanisms 202 provided on the loading outer frame 204 may be aligned with the positions of the sliding mechanisms 202 provided on the plurality of loading rods 205, or may be misaligned with the positions of the sliding mechanisms 202 provided on the plurality of loading rods 205, and no specific limitation is made here.

[0052] Since the loading rack includes a loading outer frame and a plurality of loading rods, the loading rack can have a detachable function. In this way, the battery body can be relatively simply installed into the loading rack or taken out from the loading rack, which is beneficial to improving the replacement efficiency of the battery body and reducing the replacement difficulty. In addition, since the loading outer frame is provided with a second fixing structure, the battery body in the loading rack can be relatively stably fixed, which is beneficial to avoiding the situation that the power supply device is offset due to the battery body hitting the loading rack by external force after being loaded onto the use platform.

[0053] In one embodiment, the vehicle is provided with a first locking structure 401. The loading rack 200 may include a second locking structure 206. The second locking structure 206 is provided on the outer edge of the loading outer frame 204 and cooperates with the first locking structure 401 to lock when the power supply device is loaded on the vehicle.

[0054] In one embodiment, one of the first locking structure 401 and the second locking structure 206 may be a buckle, and the other may be a lock catch. When the power supply device is loaded on the vehicle, it is locked by buckling the lock catch onto the buckle, so that the power supply device can be fixed on the vehicle.

[0055] In one embodiment, one of the first locking structure 401 and the second locking structure 206 may be a positioning hole, and the other may be a buckle. When the power supply device is loaded on the vehicle, it is locked by inserting the buckle into the positioning hole, so that the power supply device can be fixed on the vehicle.

[0056] In one embodiment, the first locking structure 401 has a hollow columnar structure, and the second locking structure 206 has an annular structure. The power supply device may further include a locking pin (not shown in the drawings), and the locking pin passes through the first locking structure 401 and the second locking structure 206 in a cooperative locking state. Among them, the annular structure may be a circular ring, a square ring, an elliptical ring, etc., and no specific limitation is made here.

[0057] Reference Figure 3 and Figures 4A to 4B , Figure 3 shows the front view structure of the vehicle frame provided by the embodiment of the present application, Figure 4A shows the front view structure of the power supply device mounting bracket provided by the embodiment of the present application, Figure 4B shows the front view structure of the power supply device mounting bracket provided by the embodiment of the present application. In one embodiment, the installation bin of the vehicle may include a power supply device mounting bracket 400, and a first locking structure 401 is installed on the power supply device mounting bracket 400. When the first locking structure 401 is installed on the power supply device mounting bracket 400 in the direction of the vehicle chassis based on the power supply device, a second locking structure 206 is located above the first locking structure 401. When the locking pin is inserted, it can be inserted through the first locking structure 401 and the second locking structure 206 at the same time.

[0058] In one embodiment, when the first locking structure 401 is installed on the power supply device mounting bracket 400 in the direction of the power supply device based on the vehicle chassis, when cooperating for locking, the first locking structure 401 can be sleeved by the second locking structure 206. When the locking pin is inserted, the locking pin is inserted through the second locking structure 206.

[0059] In one embodiment, the locking pin can be a split locking pin or a knob-type locking pin, etc., and specific limitations are not made here.

[0060] In one embodiment, the power supply device may further include a pulling member 300. The pulling member 300 can be disposed on the outer edge of the loading outer frame 204 and is on the same side as the first locking structure 401. Among them, the pulling member 300 can be one or multiple, and specific limitations are not made here. In addition, the pulling member 300 can be an externally mounted pulling handle or an embedded pulling handle, etc., and specific limitations are not made here.

[0061] In one embodiment, the pulling member 300 can be disposed in the middle of the side where the first locking structure 401 is installed, or can be disposed on one side such as the upper side, lower side, left side, and right side, etc., and specific limitations are not made here.

[0062] By providing a pulling member on the outer edge of the loading outer frame, a pulling point can be provided for technicians. In this way, when it is necessary to load or remove the power supply device, technicians can pull the power supply device more conveniently. And since the loading rack is provided with a sliding mechanism, technicians can pull the pulling member, so that the power supply device can be more easily slid for loading and removal.

[0063] In one embodiment, the battery body 100 may further include at least one power supply interface 102 and at least one communication interface 103. The power supply interface 102 is disposed on the outer edge of the battery body 100 and on the same side as the pulling member 300. The communication interface 103 is disposed on the outer edge of the battery body 100 and on the same side as the pulling member 300.

[0064] In one embodiment, the power supply interface 102 may be an interface for outputting electric energy to equipment or instruments using a power supply device. Among them, the power supply interface may be an interface with a single line (such as only being one of the positive and negative electrodes), or an integrated interface (including both the positive and negative electrodes at the same time), and specific limitations are not made here. In addition, the power supply interface may be a terminal block or a quick-connect plug and socket assembly, etc., and specific limitations are not made here. In addition, the power supply interface 102 may be one or more, and specific limitations are not made here.

[0065] In one embodiment, the communication interface 103 refers to an interface for information interaction with the power supply device to control the power supply situation of the power supply device. Among them, the communication interface 103 may be one or more, and specific limitations are not made here. In addition, the communication interface 103 may be a hybrid communication interface (such as an FEMD-35*08A-01K plug), or an interface only with communication functions, and specific limitations are not made here. In addition, the communication interface 103 may use the CAN communication protocol for communication.

[0066] In one embodiment, the communication interface 103 only has communication functions, and the power supply interface 102 may also be used for charging the battery body 100.

[0067] By disposing both the power supply interface and the communication interface on the outer edge of the battery body on the same side as the pulling member, in this way, during the process of loading or disassembling the power supply device, the connection or removal of the power supply interface and the communication interface, as well as the operation of pulling the power supply device, can be completed on the same side, which can be conducive to improving the replacement efficiency of the power supply device and reducing the replacement difficulty.

[0068] In one embodiment, the battery body 100 may further include a battery switch 104. The battery switch 104 is disposed on the outer edge of the battery body 100 and on the same side as the power supply interface 102. The battery switch 104 may be used to control the start and stop of power supply of the power supply interface.

[0069] In one embodiment, the battery switch 104 refers to a triggering device that can control the start and stop of power supply of the power supply interface. Among them, the battery switch 104 may be a button switch, a rocker switch, a knob switch or other switches, and specific limitations are not made here.

[0070] By providing a battery switch on the battery body, the start and stop of power supply to the power supply interface can be controlled. In this way, when technicians connect or disconnect the power supply interface and the communication interface of the battery body, the situation of hot plugging the power supply interface and the communication interface is reduced, thereby improving the safety of the power supply device during loading or unloading. In addition, by arranging the battery switch on the outer edge of the battery body on the same side as the power supply interface, during the process of loading or unloading the power supply device, the battery body of the battery body can be completed on the same side, which is conducive to improving the replacement efficiency of the power supply device and reducing the replacement difficulty.

[0071] In one embodiment, the battery body 100 may further include a plurality of lifting devices 105, and the plurality of lifting devices 105 are arranged on the outer edge of the battery body 100. Among them, the plurality of lifting devices 105 may all be arranged on the upper side of the battery body 100, or a plurality of lifting devices 105 may be respectively arranged on opposite sides of the battery body 100, etc., and specific details are not limited here. In addition, the lifting device 105 may be an externally mounted handle or an embedded handle, etc., and specific details are not limited here.

[0072] By providing a plurality of lifting devices on the battery body, when the battery body is installed on the loading rack or taken out from the loading rack, the lifting devices can provide lifting points, enabling technicians to more easily and conveniently install the battery body on the loading rack or take out the battery body from the loading rack.

[0073] The embodiment of the present application also provides an installation device for a power supply device. The installation device for the power supply device includes a slide rail lifting platform, and the slide rail lifting platform can be used to carry the power supply device provided in any of the above embodiments.

[0074] The embodiment of the present application also provides a vehicle, which includes an installation compartment and the power supply device provided in any of the above embodiments, and the power supply device is installed in the installation compartment. Among them, the vehicle may be a sightseeing vehicle of DN-14M-1.

[0075] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0076] In the embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can represent the cases of A existing alone, A and B existing simultaneously, and B existing alone. Here, A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one of the following" and its similar expressions refer to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, and c can represent: a existing alone, b existing alone, c existing alone, a and b existing simultaneously, a and c existing simultaneously, b and c existing simultaneously, or a, b, and c existing simultaneously, where a, b, and c can be single or multiple.

[0077] In the embodiments of the present application, "indicating" can include direct indication and indirect indication, and can also include explicit indication and implicit indication. If the information indicated by a certain piece of information is called the information to be indicated, then in the specific implementation process, there can be many ways to indicate the information to be indicated. For example, but not limited to, the information to be indicated can be directly indicated, such as indicating the information to be indicated itself or the index of the information to be indicated, etc. It is also possible to indirectly indicate the information to be indicated by indicating other information, where there is an association relationship between the other information and the information to be indicated. It is also possible to only indicate a part of the information to be indicated, while the other parts of the information to be indicated are known or pre-agreed. For example, it is also possible to rely on the arrangement order of each piece of information pre-agreed (such as stipulated in a protocol) to achieve the indication of specific information, thereby reducing the indication overhead to a certain extent.

[0078] In the embodiments of the present application, the terms and English abbreviations are all exemplary examples given for convenience of description and should not constitute any limitation to the present application. The present application does not exclude the possibility of defining other terms in existing or future protocols that can achieve the same or similar functions.

[0079] In the embodiments of the present application, the terms "first", "second", and "third" are only used for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", and "third" can explicitly or implicitly include one or more of such features.
