[0069] Substrate 3 DETAILED DESCRIPTION

[0070] A preferred embodiment is given below and combined with the accompanying drawings to more clearly and completely illustrate the present invention.

[0071] like Figure 1-5 As shown, this embodiment provides a battery-swapping robot, which is located in the battery-swapping channel of the battery-swapping station. When a vehicle enters the battery-swapping station and stays above the battery-swapping channel, the battery-swapping robot starts the battery-swapping process, moves in the battery-swapping channel, and replaces the battery pack on the vehicle chassis. The battery-swapping robot is provided with a battery-swapping unit, which is used to unlock or lock the battery pack from the vehicle chassis. The battery-swapping unit includes a substrate 3 and a torque gun array, and the torque gun array is composed of a plurality of torque guns 100 mounted on the substrate 3 and arranged in a certain pattern. A single torque gun 100 includes at least a power assembly, a transmission assembly, a sleeve assembly connected in sequence, and a torque gun mounting seat 200 corresponding to each torque gun 100.

[0072] The torque gun mounting seat 200 in this embodiment is arranged on the power exchange platform. The torque gun mounting seat 200 includes a shell 210 and a chassis 250. The shell 210 has a chamber inside, and the chamber is used to accommodate at least a part of the sleeve assembly and at least a part of the transmission assembly. The upper end of the shell 210 has a docking portion, and the sleeve assembly has a limiting portion, and the docking portion is docked with the limiting portion. The chassis 250 is connected to the lower end of the shell 210, and the chassis 250 is connected to the power assembly.

[0073] Specifically, Figure 1-5As shown, the power assembly of the torque gun 100 in this embodiment includes a motor 110 and a reducer connected to the output end of the motor 110. In order to reduce the overall volume and weight of the power assembly, a harmonic reducer 120 is selected in this embodiment. The transmission assembly of the torque gun 100 in this embodiment includes a transmission shaft 130. The rear end of the transmission shaft 130 is connected to the output end of the harmonic reducer 120, and the front end is connected to the sleeve assembly, which is used to realize the transmission between the harmonic reducer 120 and the sleeve assembly.

[0074] In this embodiment, the transmission shaft 130 is received in the housing 210 and is connected with the lower part of the sleeve assembly. In this way, the moving part of the front part of the torque gun 100 is received in the torque gun mounting seat 200, which makes full use of the internal space of the torque gun mounting seat 200 and reduces the volume of the front end of the torque gun 100.

[0075] In this embodiment, the docking portion includes a baffle structure and an opening 222, and the sleeve assembly is inserted into the opening 222. The limiting portion includes a support plate 141 and an elastic component, and the support plate 141 is received in the chamber inside the housing 210 and the support plate 141 abuts against the baffle structure. One end of the elastic component is connected to the support plate 141, and the other end is connected to the transmission component or the power component. And the elastic component is in a compressed state.

[0076] Furthermore, if Figure 1-5 As shown, in this embodiment, the upper end of the chamber inside the housing 210 has a baffle structure, including a baffle 221 and an opening 222 opened on the baffle 221. The lower part of the sleeve assembly is inserted into the opening 222, and the upper part of the sleeve assembly passes through the opening 222 and is located outside the opening 222. Through the above arrangement, a part of the sleeve assembly is arranged in the chamber inside the opening 222, and the other part of the sleeve assembly is located outside the opening 222, so as to facilitate the battery replacement operation.

[0077] Specifically, the elastic component in this embodiment is a spring 142. The spring 142 is arranged on the outside of the transmission shaft 130, one end of which is connected to the support plate 141, and the other end of which is in contact with the power assembly.

[0078] In this embodiment, the spring 142 is sleeved on the outside of the transmission shaft 130 and is used to reset the sleeve assembly to achieve the floating of the sleeve assembly in the axial direction of the transmission shaft 130. At the same time, the spring 142 is pre-compressed for a certain stroke during installation to provide an upward pre-thrust to the sleeve assembly and make the structure occupy less space and more compact. When the battery pack just contacts the sleeve assembly, it will not be displaced immediately, ensuring stability during the battery replacement process; and when the battery pack falls, the spring 142 can also make the sleeve assembly float within a range of upper and lower parts, which not only reduces the wear between components, but also reduces the precision requirements.

[0079] like Figure 1-5 As shown, the sleeve assembly of the torque gun 100 in this embodiment actually includes a lower shaft connection part 140 and an upper sleeve part. The sleeve part and the shaft connection part. The upper end of the sleeve part is used to drive the battery fastener of the battery replacement device to rotate, and the lower end of the shaft connection part is used to receive external torque rotation to drive the sleeve part to rotate. The upper end of the shaft connection part is connected to the lower end of the sleeve part. The sleeve part and the shaft connection part can be fixedly connected, or the upper end of the sleeve part can swing from the axis of the shaft connection part to the outside direction of the axis of the shaft connection part. Among them, the lower end of the shaft connection part 140 has a polygonal slot that matches the shape of the transmission shaft 130, and the transmission shaft 130 is connected to the shaft connection part 140 to achieve torque transmission. In other embodiments, the transmission shaft 130 and the shaft connection part 140 can also be docked by means of a bayonet or a latch to achieve torque transmission.

[0080] Specifically, Figure 1-5 As shown, in this embodiment, the limiting part of the sleeve assembly is a support plate 141, and the support plate 141 is arranged on the shaft connecting part 140. The upper surface of the support plate 141 is in close contact with the baffle 221, and the lower surface of the support plate 141 is in contact with the spring 142.

[0081] like Figure 1-5 As shown, the torque gun mounting base 200 includes a housing 210 and a chassis 250. The housing 210 has a chamber inside, and the chamber is used to accommodate at least a part of the sleeve assembly and at least a part of the transmission assembly. The upper end of the housing 210 has a docking portion, and the sleeve assembly has a limiting portion, and the docking portion docks with the limiting portion. The chassis 250 is connected to the lower end of the housing 210, and the chassis 250 is connected to the power assembly.

[0082] Specifically, in this embodiment, the torque gun mounting seat 200 is cylindrical in shape as a whole. The chamber of the torque gun mounting seat 200 contains the transmission shaft 130, the spring 142 and the limiting part of the sleeve assembly. The chamber accommodates the front end structure of the torque gun 100 from top to bottom in the torque gun mounting seat 200, providing a reliable protection structure. The upper side of the chassis 250 of the torque gun mounting seat 200 is connected to the lower end of the housing 210, and the lower side of the chassis 250 is connected to the harmonic reducer 120, which also increases the structural stability and makes the overall structure simple and compact.

[0083] Furthermore, the chassis 250 and the housing 210 in this embodiment are integrally formed, which not only reduces the manufacturing difficulty of the torque gun mounting base 200, but also reduces the number of components, making the structure of the torque gun mounting base 200 simpler.

[0084] like Figure 1-5As shown, the outer edge of the chassis 250 extends outward from the housing 210 to form a flange 240, and a through hole 242 is formed on the flange 240. The flange 240 is formed by extending the chassis 250 outward to increase the contact area between the chassis 250 and the plane to be installed. At the same time, the through hole 242 on the flange 240 is used to achieve installation, so that the torque gun mounting base 200 can be more stably installed on the plane to be installed.

[0085] Specifically, the plane to be installed of the torque gun mounting base 200 in this embodiment is the substrate 3 of the battery replacement unit. The torque gun mounting base 200 is installed and fixed on the substrate 3 through the through hole 242 on the flange 240. In addition, the installation position of each torque gun 100 on the substrate 3 is preset to correspond to the position of the battery pack locking piece on the vehicle.

[0086] like Figure 1-5 As shown, the outer edge of the flange 240 also has at least one notch 241 that is recessed inward. In this embodiment, there are two notches 241 on the outer edge of the flange 240, which are respectively arranged at the two ends of the same diameter of the flange 240. The notch 241 on the outer edge of the flange 240 is recessed inward to avoid other existing structures on the plane to be installed. In this way, the operator can make simple and quick adjustments to the torque gun mounting seat 200 during installation, and the torque gun mounting seat 200 is also suitable for a variety of installation positions and planes to be installed, and has good adaptability, which reduces the difficulty of installing the torque gun mounting seat 200. At the same time, in order to reduce wear between parts, the notch 241 and the outer edge of the flange 240 are transitioned by a rounded corner.

[0087] It should be noted that the notch 241 in this embodiment is to avoid the existing structure. In other embodiments of the present invention, if there is no need to avoid any structure, or the existing structure has been designed to avoid it, then there is no need to process the notch 241 on the flange 240, which can further reduce the manufacturing steps of the torque gun mounting base 200. Although the torque gun mounting base 200 in this embodiment has only two notches 241, in other embodiments, for more complex structures or installation scenarios of the plane to be installed, the number of notches 241 can be multiple.

[0088] Furthermore, in this embodiment, the lower surface of the chassis 250 is also provided with a threaded hole 243, and the chassis 250 is connected to the power assembly through threads. Specifically, the torque gun mounting seat 200 in this embodiment is connected to the holes on the motor 110 and the harmonic reducer 120 through the threaded hole 243 on the lower side of the chassis 250, and the connection and fixation are achieved by installing screws, so that the chassis 250 can be stably installed on the power assembly.

[0089] Meanwhile, as other feasible connection methods, mechanical structure connection methods such as pin connection and clamp connection can replace the threaded connection here. Those skilled in the art should understand that as long as a certain connection method can achieve the connection between two parts, it can also be used to achieve the connection between the chassis 250 and the power assembly in theory, so other solutions here will not be described in detail in this embodiment.

[0090] The housing 210 of the torque gun mounting base 200 and the chamber therein are further described below:

[0091] like Figure 1-5 As shown, the housing 210 includes first, second and third receiving sections arranged in sequence from bottom to top and interconnected. Alternatively, it may include only the first and second receiving sections.

[0092] The first receiving section 211 is connected to the chassis 250 and is used to accommodate a portion of the power assembly. Specifically, in the present embodiment, the inner wall of the first receiving section 211 is in contact with at least a portion of the outer wall of the power assembly. In order to ensure that the torque gun mounting base 200 does not undergo relative displacement with the power assembly, the inner diameter of the first receiving section 211 is equal to the outer diameter of the power assembly. In the present embodiment, the harmonic reducer 120 is received in the first receiving section 211, and the outer diameter of the harmonic reducer 120 is equal to the inner diameter of the first receiving section 211.

[0093] The purpose of the above arrangement is to reduce the overall volume of the torque gun 100, make the structure more compact, and fit better to achieve structural stability. Those skilled in the art should understand that the outer diameter of the harmonic reducer 120 is equal to the inner diameter of the first receiving section 211, which means that the two will not move significantly after being matched. In fact, it can be matched within a certain tolerance range, or it can be an interference fit to achieve the docking of the first receiving section 211 and the power assembly. In the specific implementation, the reference standards should be whether the assembly structure of the first receiving section 211 and the power assembly is stable, the working state of the two is stable when the torque gun 100 is working, and whether the installation steps are simple and feasible.

[0094] When the first, second and third receiving sections are included, the inner and outer diameters of the second receiving section 212 are smaller than the inner and outer diameters of the first receiving section 211, and the second receiving section 212 is used to accommodate the transmission shaft 130 and the spring 142. The inner diameter of the third receiving section 213 is smaller than the inner diameter of the second receiving section 212, and a docking portion is provided in the third receiving section 213, and the third receiving section 213 is used to accommodate the limiting portion on the sleeve assembly that is connected to the docking portion.

[0095] Secondly, in the present embodiment, the inner diameter of the second receiving section 212 is smaller than the inner diameter of the first receiving section 211, and the outer diameter of the second receiving section 212 is smaller than the outer diameter of the first receiving section 211. In the present embodiment, since the second receiving section 212 is mainly used to accommodate the transmission shaft 130 and the spring 142, the inner diameter requirement of the second receiving section 212 is relatively low. For the stability of the overall structure, the outer diameter of the second receiving section 212 is set to be smaller than the outer diameter of the first receiving section 211 to form a stable structure with a larger bottom and a smaller top. At the same time, since the outer diameter of the power assembly is larger, and the inner diameter required to accommodate the transmission shaft 130 and the spring 142 is smaller, the inner diameter of the second receiving section 212 is set to be smaller than the inner diameter of the first receiving section 211. Through the above-mentioned setting, the inner and outer diameters are reduced, and the volume of the torque gun mounting base 200 can be reduced.

[0096] Furthermore, if Figure 1-5 As shown, in this embodiment, the third storage section 213 is located at the upper part of the torque gun mounting base 200, and is connected to the limiting part of the sleeve assembly through the docking part. As mentioned above, the docking part is a baffle structure and an opening 222 provided on the baffle 221, and the limiting part is a support plate 141 provided on the shaft connection part 140. Such a structural form can not only meet the purpose of limiting the upward movement of the sleeve assembly, but also set a space under the support plate 141 so that the sleeve assembly can achieve a normal floating effect. However, in other embodiments of the present invention, a double-layer and / or movable baffle structure can also be provided to limit the movement of the sleeve assembly or the limiting part on the sleeve assembly within a certain travel range.

[0097] Those skilled in the art should understand that, in the above-mentioned various embodiments, the structural strength of the limiter and the docking part, the difficulty of parts assembly and the stability during operation should be taken into consideration to select the most appropriate technical solution. Although no corresponding drawings are provided in this embodiment, various changes or modifications made without departing from the essence of the present invention should all fall within the scope of protection of the present invention.

[0098] By utilizing the structure of the third receiving portion as described above, the limiting portion of the sleeve assembly can be inserted into the docking portion and received in the third receiving section 213 , and the front end structure of the torque gun 100 can be made more compact and the overall volume smaller.

[0099] In addition, if Figure 1-5 As shown, the third receiving portion in this embodiment is directly subjected to external force, so the inner wall of the third receiving portion is thickened. Reducing the inner diameter of the third receiving section 213 here not only improves the structural strength, but also enables it to better cooperate with the rear end of the sleeve assembly to obtain better structural stability.

[0100] like Figure 1-5As shown, in this embodiment, there is a smooth transition between the inner wall of the second receiving section 212 and the inner wall of the first receiving section 211, and between the outer wall of the second receiving section 212 and the outer wall of the first receiving section 211. Specifically, the inner wall of the second receiving section 212 and the inner wall of the first receiving section 211 are transitioned through an inclined surface, and the outer wall of the second receiving section 212 and the outer wall of the first receiving section 211 are transitioned through a rounded corner.

[0101] In this embodiment, since the inner diameter and the outer diameter need to be reduced when transitioning from the first storage section 211 to the second storage section 212, the above-mentioned configuration can reasonably ensure the overall structural strength of the torque gun mounting base 200 and meet the strength requirements of the torque gun mounting base 200 in actual use.

[0102] like Figure 1-5 As shown, the upper end surface of the outer surface of the third receiving section 213 has a chamfer 230 .

[0103] Specifically, in this embodiment, the outer surface of the third storage section 213 is located at the uppermost end of the torque gun mounting seat 200 and may contact other components. In order to avoid interference or wear between components, the outer surface of the third storage section 213 is chamfered 230. At the same time, the chamfer 230 can also reduce the weight of a part of the third storage section 213 while ensuring the structural strength, thereby reducing the overall weight of the torque gun mounting seat 200. On the other hand, the chamfer 230 is also easy to process, reducing the manufacturing difficulty of the torque gun mounting seat 200.

[0104] This embodiment also provides another implementation of the torque gun mounting seat:

[0105] In this embodiment, the housing includes first and second receiving sections arranged in sequence from bottom to top and connected to each other, wherein the first receiving section is the same as that in the previous embodiment, and the second receiving section is substantially the same as the third receiving section in the previous embodiment.

[0106] The difference is that the second receiving section in this embodiment not only receives the lower part of the sleeve assembly, but also completely receives the output shaft. In other words, the second receiving section in this embodiment is equivalent to integrating the two functions of the second and third receiving sections in the previous embodiment. Accordingly, in this embodiment, the first receiving section and the second receiving section have a smooth transition, and the inner diameter and outer diameter of the second receiving section are both smaller than the inner diameter and outer diameter of the first receiving section.

[0107] In this embodiment, the two end storage sections are combined to make the structure more compact, further reduce the overall volume of the torque gun mounting seat, and make it easier to process the inner and outer shapes during manufacturing. Compared with the previous embodiment, the effect is more obvious, but the requirements for structural design and mechanical verification are higher.

[0108] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
