Description

Technical Field

[0001] The utility model belongs to the field of battery swap station equipment, and in particular relates to a channel opening and closing device and a battery swap station comprising the same. Background Art

[0002] In current battery swap stations, in order to ensure the safety of the charging area connected to the battery swap area, a channel opening and closing device is usually set at the connection position between the two (i.e., the channel for the battery swap shuttle vehicle to travel), and the channel opening is opened and closed by driving the lifting door to rise and fall. In order to ensure that the lifting door can be lifted and lowered reliably, a guide mechanism is usually set on both sides of the door frame forming the channel opening, and the lifting door is guided by connecting with the lifting door. However, due to processing errors or on-site installation problems, the two sides of the door frame forming the channel opening are often non-parallel, and there is a certain parallelism error, that is, the distance between the door frames on both sides will gradually increase or decrease in the height direction, which leads to the guide mechanisms installed on both sides of the door frame being non-parallel. During the lifting and lowering process of the lifting door, the guide mechanisms on both sides guide the lifting door non-parallel, and there is a possibility of jamming during the lifting process. Even if the driving force applied to the lifting door is increased to avoid jamming, the connection between the lifting door and the guide mechanism will eventually be damaged due to unbalanced force. Therefore, the non-parallel error of the door frame at the passage opening may easily cause the lifting door to get stuck during movement, or damage the lifting door and the guide mechanism, which may increase additional maintenance and repair costs. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects in the prior art that the lifting door is easily stuck and damaged during the lifting process due to the non-parallel two sides of the door frame, and to provide a channel opening and closing device and a battery swap station including the same.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A passage opening and closing device, comprising a passage opening for a battery exchange device to enter and exit a charging area, a mounting door frame, and a lifting door arranged on the mounting door frame and capable of opening and closing the passage opening, characterized in that the passage opening and closing device further comprises:

[0006] The lifting guide mechanism includes a slide rail and a slider. The two slide rails are respectively arranged on both sides of the installation door frame along the width direction along the lifting direction of the lifting door, and the slider is slidably arranged in the corresponding slide rail;

[0007] The floating connection mechanism corresponds to the lifting guide mechanism one by one, the slider is connected to the lifting door through the floating connection mechanism, and the floating connection mechanism has freedom of movement relative to the lifting door in the width direction of the lifting door.

[0008] In the present technical solution, by arranging slide rails on both sides of the installation door frame in the width direction, the lifting door is guided by means of slide rail sliders, thereby reducing the vibration and shaking of the lifting door during movement. On this basis, by setting a floating connection mechanism corresponding to the slider, the floating connection mechanism is connected to the lifting door, and the freedom of movement between the floating connection mechanism and the lifting door along the width direction of the lifting door is utilized, so that the non-parallel error of the slide rails on both sides caused by the parallelism problem on both sides of the installation door frame can also be released by the movement between the floating connection mechanism and the lifting door in the width direction, effectively avoiding the lifting door from getting stuck or damaged. At the same time, the floating connection mechanism is still connected to the lifting door in the height direction, and the lifting accuracy of the lifting door will not be affected. Therefore, the durability of the channel opening and closing device can be improved and the maintenance cost can be reduced through this structural setting scheme.

[0009] Preferably, the floating connection mechanism includes a first mounting portion extending along the width direction of the lifting door, a surface of the first mounting portion is provided with a waisted circular hole extending along the width direction of the lifting door, and the connection portion extending from the surface of the lifting door is passed through and positioned in the waisted circular hole.

[0010] In the present technical solution, a waist-shaped hole structure extending along the width direction of the lifting door is connected to a connecting part extending from the surface of the lifting door, so as to obtain a flexible adjustment margin along the width direction through a relatively simple structural design, so that when the spacing of the installed door frame changes, the lifting door can adjust itself to adapt to different spacings through the design of the waist-shaped hole, thereby enhancing the flexibility of the lifting door adjustment.

[0011] Preferably, the lifting door includes a lifting door body, a mounting bracket and a screw. The mounting bracket is set on the surface of the lifting door body and extends outward. A threaded hole is provided on the mounting bracket. The screw passes through the oval hole of the floating connection mechanism and is threadedly connected to the threaded hole to form a connecting portion that passes through and is positioned in the oval hole.

[0012] In the technical solution, the floating connection is achieved by inserting screws into the oval holes and then connecting to the lifting door body, thereby achieving the purpose of reliable connection through a relatively simple structure. The screw and nut connection method has a simple structure and is easy to maintain, and has high structural strength, which can meet the connection strength requirements between the floating connection mechanism and the lifting door. In addition, by arranging a mounting bracket on the surface of the lifting door body to form a threaded hole, the sealing problem caused by directly opening a hole on the lifting door body is avoided.

[0013] Preferably, a bushing is provided on the screw, and the bushing is sleeved on the screw and located between the waist-shaped holes;

[0014] The threaded holes on the mounting bracket are formed by welding nuts;

[0015] The screw is also provided with a gasket which is sleeved on the screw, and the gasket is clamped between the screw and the first mounting part.

[0016] In the present technical solution, the design of the bushing helps to reduce the direct friction between the screw and the oval hole, helps to reduce the wear caused by friction during the adjustment of the lifting door, and extends the service life of the screw and the oval hole.

[0017] Moreover, the threaded hole is formed by welding nuts, which is convenient for processing and has high structural strength, meeting the connection strength requirements between the floating connection mechanism and the lifting door. In addition, since the distance between the mounting bracket and the lifting door is small, in order to make full use of the limited space and ensure the stable connection between the screw and the mounting bracket, a welding nut is selected as a fixing part on the side of the mounting bracket facing the lifting door. Such a design can not only optimize the space utilization, ensure that the structure between the screw, the mounting bracket and the lifting door is more compact, but also ensure the reliable connection between the mounting bracket and the floating connection mechanism.

[0018] At the same time, the spacer is sandwiched between the screw and the first mounting part to reduce direct contact between the two, which helps to reduce friction between the two, provides a buffering and protective effect, thereby reducing wear and extending the service life of the screw and the first mounting part. In addition, the spacer is sandwiched between the screw and the first mounting part to help improve the stability between the screw and the first mounting part, and prevent the shaking and instability caused by the unstable connection during the movement of the lifting door.

[0019] Preferably, the radial length of the screw is smaller than the shortest distance between the oblong holes along the height direction of the lifting door;

[0020] And / or, a gap is formed between the screw and the oval hole.

[0021] In the present technical solution, the design with a gap allows the lifting door to move horizontally in the waist-round hole by itself, facilitating its adjustment and reducing the risk of the lifting door getting stuck or jammed due to the friction between the screw and the waist-round hole during adjustment, helping to ensure smooth movement and flexible adjustment of the lifting door and avoiding abnormal stagnation due to excessive resistance.

[0022] Preferably, the two slide rails are arranged opposite to each other and are both arranged on the inner side of the installation door frame.

[0023] In this technical solution, the slide rail is arranged on the inner side of the door frame to reasonably utilize the space and avoid the lifting guide mechanism occupying the space outside the door frame and affecting the arrangement of other equipment adjacent to the passage opening and closing device.

[0024] Preferably, the floating connection mechanism further comprises a second mounting portion, the second mounting portion is used to be connected to the slider, and the second mounting portion and the first mounting portion are arranged in an L shape;

[0025] A reinforcement structure is disposed between the first mounting portion and the second mounting portion.

[0026] In the present technical solution, the design of the L-shaped arrangement between the second mounting portion and the first mounting portion to form a bending structure and the provision of an additional reinforcement structure provide a more solid and stable connection method, which helps to improve the reliability and stability of the connection between the components in the floating connection mechanism.

[0027] Preferably, a through hole is provided on a side surface of the second mounting portion facing the mounting door frame, and the through hole is used for the abutment member to pass through and abut against the slide rail.

[0028] In the present technical solution, the design of the through hole allows the setting of abutments or other fixing devices to fix the lifting door at a specific position relative to the mounting door frame, thereby ensuring a more stable connection between the lifting door and the mounting door frame, preventing the lifting door from accidentally loosening or falling off relative to the mounting door frame during bumpy transportation, thereby improving safety during transportation and the integrity of the lifting door and the surrounding environment.

[0029] Preferably, there are multiple floating connection mechanisms, which are arranged in pairs on both sides of the lifting door.

[0030] In the present technical solution, the floating connection mechanisms arranged in pairs can provide more stable support for the lifting door, preventing the lifting door from tilting or shaking during movement. At the same time, the arrangement of multiple floating connection mechanisms can improve the adjustment flexibility of the lifting door in the horizontal direction. Each floating connection mechanism can be adjusted independently to adapt to the installation door frame spacing at different positions, thereby enhancing the adaptability of the channel opening and closing device. In addition, if a floating connection mechanism on one side fails, it will not completely affect the adjustment of the entire lifting door, which can reduce the risk of invalid adjustment of the channel opening and closing device due to the failure of a certain floating connection mechanism, thereby improving the reliability of the floating connection mechanism.

[0031] A battery swap station, comprising any one of the above-mentioned channel opening and closing devices.

[0032] In the present technical solution, the channel opening and closing device using the above-mentioned structural form can effectively control the opening and closing of the channel opening in the battery swap station, provide a flexible operating channel for the battery swap equipment, and realize safe and orderly battery replacement services.

[0033] The positive and progressive effects of the utility model are:

[0034] 1. The passage opening and closing device arranges sliding rails on both sides of the installation door frame along the width direction, guides the lifting door by means of sliding rail sliders, and reduces the vibration and shaking of the lifting door during movement. On this basis, a floating connection mechanism corresponding to the slider is provided, and the floating connection mechanism is connected to the lifting door. The freedom of movement between the floating connection mechanism and the lifting door along the width direction of the lifting door is utilized, so that the non-parallel error of the sliding rails on both sides caused by the parallelism problem on both sides of the installation door frame can also be released by the movement between the floating connection mechanism and the lifting door along the width direction, effectively avoiding the lifting door from getting stuck or damaged. At the same time, the floating connection mechanism remains connected to the lifting door in the height direction, and the lifting accuracy of the lifting door will not be affected. Therefore, the durability of the passage opening and closing device can be improved and the maintenance cost can be reduced through this structural setting scheme.

[0035] 2.

[0065] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0066] The utility model provides a battery swap station for providing battery swap services to vehicles entering the battery swap station, wherein the battery swap station includes a battery swap area and a charging area, the area for vehicles to enter is the battery swap area, and battery swap equipment is provided in the battery swap area to disassemble and assemble the batteries loaded on the vehicle. After the disassembly and assembly are completed, the battery swap equipment will enter the charging area through the passageway to charge the battery removed from the vehicle. In order to separate the charging area from the battery swap area without affecting the normal driving of the battery swap equipment, a passageway opening and closing device 100 will also be provided at the passageway 11 of the battery swap station.

[0067] This embodiment provides a preferred structural arrangement scheme for a channel opening and closing device 100. Figure 1 As shown, by driving the lifting door 13 to lift, the passage opening and closing device 100 can close and open the passage opening 11 of the battery swap station. Figure 1 In the embodiment, the lifting door 13 of the passage opening and closing device 100 is located at the lowest point to close the passage opening 11. The passage opening and closing device 100 further specifically includes a mounting door frame 12, a lifting guide mechanism 14 and a floating connection mechanism 15.

[0068] Regarding the installation of the door frame 12, the structure in this embodiment is as Figure 2 shown. It is usually in the shape of "冂", or can also be in the shape of "口". The lower area inside it encloses the passage opening 11, and the upper area inside is used to accommodate various driving devices in the passage opening opening and closing device 100, and to provide the space required for the lifting door 13 to rise. Among them, due to the large structural size and the constraints of installation and processing errors and other factors, the left and right sides of the installation door frame 12 are not completely parallel. Therefore, when the lifting door 13 slides and positions on the left and right sides of the installation door frame 12, it is easy to get stuck during the lifting process of the lifting door 13 due to the non-parallel position relationship on both sides, or the maintenance frequency is high due to excessive wear.

[0069] To solve this problem, in this embodiment, a lifting guiding mechanism 14 is provided. The lifting door 13 is slidably positioned on the left and right sides of the installation door frame 12 through the lifting guiding mechanism 14. Among them, as Figure 3 shown, the lifting guiding mechanism 14 specifically includes a slide rail 141 and a slider 142. Two slide rails 141 are respectively arranged on the left and right side surfaces of the installation door frame 12 along the width direction along the lifting direction of the lifting door 13, and the slider 142 is slidably arranged in the corresponding slide rail 141, and the slider 142 is connected to the lifting door 13 to achieve the purpose of the lifting door 13 moving along the extending direction of the slide rail 141, that is, the up and down direction. By arranging the slide rails 141 on both sides of the installation door frame 12 along the width direction, the guiding of the lifting door 13 is realized through the slide rail 141 and the slider 142, reducing the vibration and shaking generated during the movement of the lifting door 13.

[0070] To solve the influence of the non-parallelism of the left and right sides of the installation door frame 12 on the lifting door 13, a floating connection mechanism 15 is further provided in this embodiment. The connection between the slider 142 and the lifting door 13 is realized through the floating connection mechanism 15. Specifically, the floating connection mechanism 15 is provided in one-to-one correspondence with the slider 142 on the lifting guiding mechanism 14. The slider 142 is connected to the lifting door 13 through the corresponding floating connection mechanism 15, and the floating connection mechanism 15 has a degree of freedom of movement in the width direction of the lifting door 13 relative to the lifting door 13, so that the error of the non-parallelism of the two side slide rails caused by the parallelism problem of the two sides of the installation door frame 12 can also be released through the movement in the width direction between the floating connection mechanism 15 and the lifting door 13, so as to solve a series of problems caused by non-parallelism on both sides from the root cause, effectively avoiding the jamming or damage of the lifting door 13. At the same time, the floating connection mechanism 15 still maintains a connection with the lifting door 13 in the height direction, and the lifting accuracy of the lifting door 13 will not be affected. Therefore, through this structural setting scheme, the service durability of the passage opening opening and closing device 100 can be improved, and the maintenance cost can be reduced.

[0071] It should be clearly stated that, in this embodiment, Figure 1 As shown, when the lifting door 13 is in the closed state, it completely covers the passage opening 11, so as to effectively prevent people and foreign objects from invading the charging area of ​​the battery swap station, and improve the isolation effect between the charging area and the outside world, meeting the requirements of dust prevention, heat preservation, etc. Of course, in other embodiments, the lifting door 13 can also half-cover or partially cover the passage opening 11 as needed, and the specific coverage degree can be set as needed according to actual needs.

[0072] like Figure 1 As shown, the number of sliders 142 and floating connection mechanisms 15 is four, and they are arranged in pairs on both sides of the lifting door 13. In this embodiment, the sliders 142 and floating connection mechanisms 15 arranged in pairs can provide more stable support for the lifting door 13, preventing the lifting door 13 from tilting or shaking during movement. At the same time, the provision of multiple floating connection mechanisms 15 can improve the adjustment flexibility of the lifting door 13 in the horizontal direction, and each floating connection mechanism 15 can be adjusted independently to adapt to the spacing of the door frame 12 installed at different positions, thereby enhancing the adaptability of the passage opening and closing device 100. In addition, if the floating connection mechanism 15 on one side fails, it will not completely affect the adjustment of the entire lifting door 13, which can reduce the risk of invalid adjustment of the passage opening and closing device 100 due to the failure of a certain floating connection mechanism 15, thereby improving the reliability of the floating connection mechanism 15.

[0073] This embodiment provides a specific structural arrangement of a floating connection mechanism 15: Figure 3-Figure 4 As shown, the floating connection mechanism 15 includes a first mounting portion 151 extending in the width direction of the lifting door 13, and a waisted hole 1511 extending in the width direction of the lifting door 13 is provided on the surface of the first mounting portion 151, and the connection portion extending from the surface of the lifting door 13 is passed through and positioned in the waisted hole 1511. The waisted hole 1511 extending in the width direction of the lifting door 13 is connected with the connection portion extending from the surface of the lifting door 13, so that the margin can be flexibly adjusted in the width direction through a relatively simple structural design, so that when the spacing of the door frame 12 is changed, the lifting door 13 can adjust itself to adapt to different spacings through the design of the waisted hole 1511, thereby enhancing the flexibility of adjustment of the lifting door 13.

[0074] Furthermore, if Figure 3-Figure 4As shown, the lifting door 13 includes a lifting door body 131, a mounting bracket 132 and a screw 133. The mounting bracket 132 is arranged on the surface of the lifting door body 131 and extends outward, that is, extends in the direction of the first mounting portion 151. A threaded hole is arranged on the mounting bracket 132. The screw 133 passes through the oval hole 1511 of the floating connection mechanism 15 and is then threadedly connected to the threaded hole, that is, connected to the mounting bracket 132, so as to form a connection portion that is penetrated and positioned in the oval hole 1511. The floating connection is achieved by penetrating the screw 133 through the oval hole 1511 and then connecting to the lifting door body 131. The purpose of reliable connection is achieved through a relatively simple structure. The connection method of the screw 133 and the nut is simple in structure and easy to maintain. The structural strength is high, and the connection strength requirement between the floating connection mechanism 15 and the lifting door 13 can be met. In addition, by arranging the mounting bracket 132 on the surface of the lifting door body 131 to form a threaded hole, the sealing problem caused by directly opening a hole on the lifting door body 131 is avoided.

[0075] Preferably, in this embodiment, the threaded hole on the mounting bracket 132 is formed by welding the nut 136. The threaded hole is formed by welding the nut 136, which is convenient for processing and has high structural strength, and meets the connection strength requirements between the floating connection mechanism 15 and the lifting door 13. In addition, since the distance between the mounting bracket 132 and the lifting door 13 is small, in order to make full use of the limited space and ensure the stable connection between the screw 133 and the mounting bracket 132, a welding nut 136 is selected as a fixing member on the side of the mounting bracket 132 facing the lifting door 13. Such a design can not only optimize the space utilization, ensure that the structure between the screw 133, the mounting bracket 132 and the lifting door 13 is more compact, but also ensure the reliable connection between the mounting bracket 132 and the floating connection mechanism 15.

[0076] In addition, if Figure 4 As shown, a bushing 134 is provided on the screw 133 and is located between the oval holes 1511. The design of the bushing 134 helps to reduce the direct friction between the screw 133 and the oval holes 1511, helps to reduce the wear caused by friction during the adjustment of the lifting door 13, and extends the service life of the screw 133 and the oval holes 1511.

[0077] Furthermore, a washer 135 sleeved on the screw 133 is provided on the screw 133, and the washer 135 is sandwiched between the screw 133 and the first mounting portion 151, which can reduce direct contact between the two, help reduce friction between the two, provide a buffering and protective effect, thereby reducing wear and extending the service life of the screw 133 and the first mounting portion 151. In addition, the sandwiching of the washer 135 also helps to improve the stability between the screw 133 and the first mounting portion 151, and prevents shaking and instability caused by unstable connection during the movement of the lifting door 13.

[0078] like Figure 4 As shown, the radial length of the screw 133 is smaller than the shortest distance between the oval hole 1511 along the height direction of the lifting door 13. At the same time, a gap is formed between the screw 133 and the oval hole 1511. That is to say, when the screw 133 is in the oval hole 1511, a gap is provided between the screw 133 and the oval hole 1511 along the circumferential direction of the screw 133.

[0079] In this embodiment, the gap design allows the lifting door 13 to move horizontally in the oval hole 1511 by itself, which facilitates its adjustment and reduces the risk of the lifting door 13 getting stuck or stuck due to the friction between the screw 133 and the oval hole 1511 during the adjustment process. It helps to ensure the smooth movement and flexible adjustment of the lifting door 13 and avoid abnormal stagnation due to excessive resistance.

[0080] like Figure 1 As shown, the two slide rails 141 are arranged opposite to each other and are both arranged on the inner side of the door frame 12 .

[0081] In this embodiment, the slide rail 141 is arranged on the inner side of the door frame 12 to reasonably utilize the space and prevent the lifting guide mechanism 14 from occupying the space outside the door frame 12 and affecting the arrangement of other equipment adjacent to the passage opening and closing device 100.

[0082] The floating connection mechanism 15 further includes a second mounting portion 152 for connecting with the slider 142. Figure 3 It can be seen from the figure that the second mounting portion 152 is connected to the edge of the first mounting portion 151, and the positional relationship between the two is L-shaped. Specifically, in this embodiment, the first mounting portion 151 and the second mounting portion 152 are integrated.

[0083] In addition, a reinforcement structure 153 is provided between the first mounting portion 151 and the second mounting portion 152. The reinforcement structure 153 is provided at a position as shown in FIG. Figure 3As shown, the reinforcing structure 153 is sandwiched between the second mounting portion 152 and the first mounting portion 151, which are bent structures. The adjacent two side surfaces of the reinforcing structure 153 are respectively arranged perpendicular to the surface between the second mounting portion 152 and the first mounting portion 151, and are connected by welding. In other embodiments, multiple reinforcing structures 153 may also be arranged between the first mounting portion 151 and the second mounting portion 152 to improve the reinforcing capacity. In this embodiment, only one reinforcing structure 153 is arranged to avoid the reinforcing structure 153 affecting the installation of fasteners such as screws.

[0084] In this embodiment, the second mounting portion 152 and the first mounting portion 151 are arranged in an L-shape, i.e., a bent structure, and the reinforcement structure 153 are added to help improve the reliability and stability of the connection between the components in the floating connection mechanism 15 .

[0085] like Figure 3-Figure 4 As shown, a through hole 1521 is provided on one side surface of the second mounting portion 152 facing the mounting door frame 12 , that is, the through hole 1521 is penetrated through the second mounting portion 152 along the width direction of the mounting door frame 12 for allowing the abutment member to pass through and abut on the slide rail 141 .

[0086] In this embodiment, the design of the through hole 1521 allows for the provision of an abutment or other fixing device to fix the lifting door 13 at a specific position relative to the mounting door frame 12, thereby ensuring a more stable connection between the lifting door 13 and the mounting door frame 12, preventing the lifting door 13 from accidentally loosening or falling off relative to the mounting door frame 12 during bumpy transportation, thereby improving safety during transportation and the integrity of the lifting door 13 and the surrounding environment.

[0087] The channel opening and closing device 100 in this embodiment is used in a battery swap station to realize the opening and closing of the channel opening 11 of the battery swap station. However, in other embodiments, the channel opening and closing device 100 can also be used in other equipment in the field of battery swapping to also realize the purpose of reliably opening and closing the channel opening 11.

[0088] like Figure 1As shown, the passage opening and closing device 100 also includes a stroke amplification mechanism 16, a driving mechanism 17 and a counterweight mechanism 18. Among them, the counterweight mechanism 18 is used to balance the weight of the lifting door 13, so that the driving mechanism 17 can drive the lifting door 13 to lift and lower through a smaller load. The stroke amplification mechanism 16 is used to realize the transmission between the lifting door 13 and the counterweight mechanism 18 and the driving mechanism 17. The stroke amplification mechanism 16 further includes a first stroke amplification part 161 and a second stroke amplification part 162, which correspond to the driving mechanism 17 and the counterweight mechanism 18 respectively, to amplify the driving stroke, so that the driving mechanism 17 and the counterweight mechanism 18 can drive the lifting door 13 to a larger position through a smaller displacement. Specifically, the driving mechanism 17 is connected to the lifting door 13 through the first stroke amplification part 161, and the counterweight mechanism 18 is connected to the lifting door 13 through the second stroke amplification part 162. Specifically in this embodiment, Figure 1 As shown, the first stroke amplification part 161 and the second stroke amplification part 162 of the stroke amplification mechanism 16 both realize stroke amplification by means of a movable pulley. Due to the stroke amplification feature of the movable pulley, the amplified stroke ratio is 1:2, that is, the driving mechanism 17 produces a displacement of 1, which can drive the lifting door 13 to move a displacement of 2, so that the driving mechanism 17 and the counterweight mechanism 18 can drive the lifting door 13 to move a larger amplitude only by a relatively small movement, so that the driving mechanism 17 and the counterweight mechanism 18 can be set in the installation door frame 12, and will not affect the normal passage at the passage opening 11 due to the large movement amplitude.
