The battery replacing part comprises a substrate 3 and a torque gun array, wherein the torque gun array is formed by arranging a plurality of torque guns 100 arranged on the substrate 3 according to a certain rule. The single torque gun 100 includes at least a power assembly, a transmission assembly, a sleeve assembly, and a torque gun mount 200 in one-to-one correspondence with each torque gun 100, connected in sequence.

The torque gun mount 200 in this embodiment is disposed on the charging platform. The torque gun mount 200 includes, among other things, a housing 210 and a chassis 250. The housing 210 has a cavity therein, the cavity is at least used for accommodating a part of the sleeve assembly and at least a part of the transmission assembly, the upper end of the housing 210 has a butt joint portion, the sleeve assembly has a limit portion, the butt joint portion is in butt joint with the limit portion, the chassis 250 is connected with the lower end of the housing 210, and the chassis 250 is connected with the power assembly.

The rear end of the transmission shaft 130 is connected with the output end of the harmonic speed reducer 120, and the front end is connected with the sleeve assembly, so as to realize transmission between the harmonic speed reducer 120 and the sleeve assembly.

In the present embodiment, the transmission shaft 130 is received in the housing 210 and is connected to the lower portion of the sleeve assembly. Thus, the moving part of the front part of the torque gun 100 is accommodated in the torque gun mounting seat 200, the internal space of the torque gun mounting seat 200 is fully utilized, and the volume of the front end of the torque gun 100 is reduced.

Through the arrangement, one part of the sleeve assembly is arranged in the cavity inside the opening 222, and the other part of the sleeve assembly is located outside the opening 222, so that the battery replacement operation is convenient.

Specifically, the elastic member in the present embodiment is a spring 142. The spring 142 is disposed outside the transmission shaft 130, and has one end connected to the supporting plate 141 and the other end abutting against the power assembly.

In this embodiment, the spring 142 is sleeved outside the transmission shaft 130 and is used for resetting the sleeve assembly to realize the floating of the sleeve assembly in the axial direction of the transmission shaft 130. At the same time, spring 142 is pre-compressed for a stroke during installation to provide an upward pre-jacking force on the sleeve assembly and to make the structure less space consuming and more compact. When the battery pack just contacts the sleeve component, the displacement cannot occur immediately, so that the stability in the battery replacement process is ensured; when the battery pack falls, the spring 142 enables the sleeve assembly to float in an upper section and a lower section, so that the abrasion between parts is reduced, and the precision requirement is also lowered.

As shown in fig. 1 to 5, the sleeve assembly of the torque gun 100 in this embodiment actually includes a lower shaft coupling portion 140 and an upper sleeve portion, the upper end of the sleeve portion of the shaft coupling portion is used for driving the battery fastener of the device to be charged to rotate, the lower end of the shaft coupling portion is used for receiving external torque to rotate so as to drive the sleeve portion to rotate, the upper end of the shaft coupling portion is connected with the lower end of the sleeve portion, and the sleeve portion and the shaft coupling portion may be fixedly connected, or the upper end of the sleeve portion may be capable of swinging from the axis of the shaft coupling portion to the outside direction of the axis of the shaft coupling portion. The lower end of the shaft connecting part 140 has a polygonal slot matching the shape of the transmission shaft 130, and the transmission shaft 130 is connected with the shaft connecting part 140 in a matching manner to realize torque transmission. In other embodiments, the transmission shaft 130 and the shaft connecting portion 140 may be connected by a bayonet or a plug, and thus may transmit torque.

Specifically, as shown in fig. 1 to 5, in the present embodiment, the limiting portion of the sleeve assembly is a supporting plate 141, and the supporting plate 141 is disposed on the coupling portion 140. The upper surface of the retainer plate 141 is in close contact with the stopper 221, and the lower surface of the retainer plate 141 is in contact with the spring 142.

As shown in fig. 1-5, the torque gun mount 200 includes a housing 210 and a chassis 250. The housing 210 has a cavity therein, the cavity is at least used for accommodating a part of the sleeve assembly and at least a part of the transmission assembly, the housing 210 has an upper end with a butting portion, the sleeve assembly has a limiting portion, and the butting portion is butted with the limiting portion. The base plate 250 is coupled to the lower end of the housing 210, and the base plate 250 is coupled to the power module.

Specifically, in the present embodiment, the torque gun mount 200 is cylindrical as a whole. The torque gun mount 200 houses the drive shaft 130, spring 142, and the stop portion of the sleeve assembly within a cavity. The chamber receives the front structure of the torque gun 100 entirely within the torque gun mount 200 from top to bottom, providing a reliable protective structure. The upper side of the chassis 250 of the torque gun mounting seat 200 is connected with the lower end of the shell 210, and the lower side of the chassis 250 is connected with the harmonic reducer 120, so that the structural stability is improved, and the whole structure is simple and compact.

Further, the chassis 250 and the housing 210 in this embodiment are integrally formed, which not only reduces the manufacturing difficulty of the torque gun mount 200, but also reduces the number of components, and makes the structure of the torque gun mount 200 simpler.

As shown in fig. 1-5, the outer edge of the bottom plate 250 extends to the outside of the housing 210 to form a flange 240, and the flange 240 is provided with a through hole 242 penetrating up and down. The flange 240 is formed by extending the base plate 250 outwards to increase the contact area of the base plate 250 and the plane to be installed, and the torque gun mounting base 200 can be more stably installed on the plane to be installed by using the through hole 242 on the flange 240.

Specifically, the surface to be mounted of the torque gun mount 200 in the present embodiment is the substrate 3 of the power exchanging portion. The torque gun mount 200 is mounted and fixed to the base plate 3 through a through hole 242 of the flange 240. Also, the mounting position of each torque gun 100 on the base plate 3 is preset to correspond to the position of the battery pack lock member on the vehicle.

As shown in fig. 1-5, the outer edge of the flange 240 also has at least one notch 241 that is inwardly recessed. In this embodiment, there are two notches 241 on the outer edge of the flange 240, which are respectively disposed at two ends of the flange 240 with the same diameter. The notch 241 on the outer edge of the flange 240 is recessed inward for avoiding other existing structures on the plane to be mounted. Thus, the torque gun mounting base 200 can be simply and quickly adjusted by an operator during installation, and the torque gun mounting base 200 is also suitable for various installation positions and planes to be installed, has good adaptability, and reduces the installation difficulty of the torque gun mounting base 200. Meanwhile, in order to reduce the abrasion between the parts, the gap 241 and the outer edge of the flange 240 are in round transition.

Note that the notch 241 in this embodiment is for avoiding the conventional structure. In other embodiments of the present invention, if there is no need to avoid any structure or design an existing structure to avoid the existing structure during design, there is no need to form the notch 241 on the flange 240, and thus the manufacturing steps of the torque gun mounting base 200 can be further reduced. Although the torque gun mount 200 of the present embodiment has only two notches 241, in other embodiments, the number of notches 241 may be more than one for more complex planar structures or mounting scenarios.

Further, in this embodiment, a threaded hole 243 is further formed in the lower surface of the chassis 250, and the chassis 250 is connected to the power assembly through a thread. Specifically, the torque gun mount 200 in this embodiment is butted against holes of the motor 110 and the harmonic reducer 120 through a threaded hole 243 on the lower side of the chassis 250, and the butting and fixing are achieved through mounting screws, so that the chassis 250 can be stably mounted on the power assembly.

Meanwhile, as other feasible connection modes, the connection modes of mechanical structures such as pin connection, clamping connection and the like can replace the threaded connection. It should be understood by those skilled in the art that, as long as a certain connection mode can achieve connection between two parts, it can be theoretically used for achieving connection between the chassis 250 and the power assembly, and therefore, other solutions herein are not described in detail in this embodiment.

The housing 210 of the torque gun mount 200 and its internal cavity are further described below:

as shown in fig. 1 to 5, the housing 210 includes first, second and third receiving sections sequentially arranged from bottom to top and communicating with each other. It is also possible to include only the first and second receiving sections.

The first receiving section 211 is connected to the chassis 250 for receiving a portion of the power assembly. Specifically, in the present embodiment, the inner wall of the first receiving section 211 is attached to at least a portion of the outer side wall of the power assembly. To ensure that the torque gun mount 200 does not displace relative to 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 housed in the first housing section 211, and the outer diameter of the harmonic reducer 120 is equal to the inner diameter of the first housing section 211.

The purpose of the above arrangement is to make the torque gun 100 smaller in overall size, more compact in structure, and fit for better structural stability. It should be understood by those skilled in the art 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 harmonic reducer and the first receiving section 211 do not move greatly after being fitted, and actually, the first receiving section 211 and the power assembly may be fitted within a certain tolerance range, or may be in an interference fit manner. In the implementation, the reference criteria should be that the first receiving section 211 and the power assembly assembling structure are stable, the working state of the torque gun 100 is stable, and the installation steps are simple and feasible.

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 for accommodating the transmission shaft 130 and the spring 142. The inner diameter of the third accommodating section 213 is smaller than the inner diameter of the second accommodating section 212, a butt joint portion is arranged in the third accommodating section 213, and the third accommodating section 213 is used for accommodating a limiting portion on the sleeve assembly in butt joint with the butt joint portion.

Next, 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 for accommodating the transmission shaft 130 and the spring 142, the requirement for the inner diameter of the second receiving section 212 is low. For stability of the entire structure, an outer diameter of the second receiving section 212 is set to be smaller than that of the first receiving section 211 to form a stable structure having a large lower portion and a small upper portion. Meanwhile, since the outer diameter of the power assembly is large and the inner diameter required to accommodate the transmission shaft 130 and the spring 142 is small, the inner diameter of the second receiving section 212 is set to be smaller than the inner diameter of the first receiving section 211. With the above arrangement, the inner and outer diameters are reduced, and the volume of the torque gun mount 200 can be reduced.

Further, as shown in fig. 1 to 5, in the present embodiment, the third receiving section 213 is located at an upper portion of the torque gun mount 200 and is abutted with the limiting portion of the sleeve assembly through the abutting portion. As described above, the abutting portion is a baffle structure and the opening 222 is formed in the baffle 221, and the limiting portion is the support plate 141 disposed on the coupling portion 140. The structure can not only meet the purpose of limiting the upward movement of the sleeve assembly, but also set a space below the supporting plate 141 to enable the sleeve assembly to normally realize the floating effect. However, in other embodiments of the present invention, a double-layer and/or movable baffle structure may be provided to limit the movement of the sleeve assembly or the limiting portion on the sleeve assembly within a certain range of the stroke.

It will be appreciated by those skilled in the art that in the above embodiments, the most suitable technical solution should be selected taking into consideration the structural strength of the limiting portion and the abutting portion, the difficulty of assembling the parts, and the stability during operation. Although the drawings in the present embodiment are not provided for illustration, various changes or modifications may be made without departing from the spirit of the invention.

By using the structure of the third accommodating portion, the limiting portion of the sleeve assembly can be inserted into the abutting portion and accommodated in the third accommodating section 213, and the front end of the torque gun 100 can be more compact and smaller in overall size.

In addition, as shown in fig. 1 to 5, the third accommodating portion in the present embodiment is directly subjected to an external force, so that the inner wall of the third accommodating portion is designed to be thickened. Reducing the inner diameter of the third receiving section 213 here enables a better fit with the rear end of the sleeve assembly for better structural stability, in addition to improved structural strength.

As shown in fig. 1 to 5, in the present embodiment, the inner wall of the second receiving section 212 and the inner wall of the first receiving section 211, and the outer wall of the second receiving section 212 and the outer wall of the first receiving section 211 are smoothly transited. Specifically, the inner wall of the second receiving section 212 and the inner wall of the first receiving section 211 are in a transition through an inclined plane, and the outer wall of the second receiving section 212 and the outer wall of the first receiving section 211 are in a transition through a rounded corner.

In this embodiment, because need reduce internal diameter and external diameter when accomodating section 212 transition from first accomodating section 211 to the second, through above-mentioned setting, can rationally guarantee the overall structure intensity of moment of torsion rifle mount pad 200, satisfy the intensity demand of moment of torsion rifle mount pad 200 when in actual use.

As shown in fig. 1-5, the upper end surface of the outer surface of the third receiving section 213 has a chamfer relief 230.

Specifically, in the present embodiment, the outer surface of the third receiving section 213 is located at the uppermost end of the torque gun mount 200, and may contact other components. To avoid interference or wear between the components, the outer surface of the third receiving section 213 is chamfered 230. Meanwhile, the chamfer avoiding 230 can reduce the weight of a part of the third accommodating section 213 on the premise of ensuring the structural strength, so that the overall weight of the torque gun mounting seat 200 is reduced. On the other hand, the chamfer relief 230 also facilitates machining, reducing the manufacturing difficulty of the torque gun mount 200.

The present embodiments also provide another implementation of a torque gun mount:

in this embodiment, the housing includes first and second receiving sections arranged in order from the bottom up and communicating with each other. The first receiving section is the same as that of the previous embodiment, and the second receiving section is substantially the same as that of the third receiving section of the previous embodiment.

The difference is that the second housing section in this embodiment not only houses the lower portion of the sleeve assembly, but also completely houses the output shaft. That is, the second housing section in the present embodiment corresponds to a combination of the two functions of the second and third housing sections in the previous embodiment. Accordingly, in the present embodiment, the first receiving section and the second receiving section are in smooth transition, and both the inner diameter and the outer diameter of the second receiving section are smaller than those of the first receiving section.

In the embodiment, the original two end accommodating sections are combined, so that the structure is more compact, the whole volume of the torque gun mounting seat is further reduced, and the shapes of the inner side and the outer side of the torque gun mounting seat are easier to process during manufacturing. Compared with the former embodiment, the effect is more obvious, but the requirements on structural design and mechanical verification are higher.

While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
