DETAILED DESCRIPTION

[0057] The utility model will be further explained by the way of embodiment below, but will not limit the utility model in the embodiment range because of this.

[0058] Embodiment 1

[0059] The utility model embodiment provides a guide assembly 30, as Figure 1 And Figure 2 Indicated, guide assembly 30 is used to guide the movement between first assembly 2 and second assembly 3, and guide assembly 30 includes at least two guide rods, and at least two guide rods are connected in turn, and every two adjacent guide rods are rotatably connected at its end portion;Leading end guide rod 111 and trailing end guide rod 112 in at least two guide rods are rotatably connected with first assembly 2 and second assembly 3 respectively, so that at least two guide rods are expanded or compressed with the movement between first assembly 2 and second assembly 3.Guide rod is rotatably connected between guide rod, and guide rod is also rotatably connected with first assembly 2 and second assembly 3, compared with other guide modes, the length of guide rod can be configured according to demand, and when multiple guide rods are expanded, the expansion distance is longer, so that longer guide stroke can be possessed.In addition, when it is compressed, multiple guide rods can be compressed more compactly in its guide direction GD, and the space occupied by it in guide direction GD is reduced.

[0060] In specific implementation, the guide rod in guide assembly 30 is at least two, when it is two, the two guide rods are leading end guide rod 111 and trailing end guide rod 112 connected with first assembly 2 and second assembly 3 respectively.When it is more than two, as Figure 2As shown in Figs. 1 and 2, the guide rods at both ends of the guide assembly 30 are respectively a leading guide rod 111 and a trailing guide rod 112, which are connected with the first assembly 2 and the second assembly 3; and there is one or more intermediate guide rods 113 between the leading guide rod 111 and the trailing guide rod 112. In these leading guide rod 111, intermediate guide rod 113 and trailing guide rod 112, every two adjacent guide rods are rotatably connected at their ends, and the leading guide rod 111 at its leading end and the trailing guide rod 112 at its trailing end can be connected with the first assembly 2 and the second assembly 3. According to the guide requirement, the guide assembly 30 can be configured with a corresponding number of guide rods, and the guide stroke is longer as the number of guide rods increases; when the number of guide rods is small, the thickness of the guide assembly 30 can be thinner.

[0061] As shown in Figs. 1 and 2, Figure 1 , Figure 3 and Figure 4 , the guide direction GD of the guide assembly 30 is consistent with the moving direction of the first assembly 2 and the second assembly 3. As shown in Figs. 1 and 2, Figure 3 and Figure 4 , the first assembly 2 and the second assembly 3 each have a plate body for the guide assembly 30 to connect, and the two plate bodies are arranged in a spaced manner, and the guide assembly 30 is arranged between the two plate bodies.

[0062] As shown in Figs. 1 and 2, Figures 1-7 , at least two guide rods are stacked along the thickness direction T of the guide rod. A plurality of guide rods are stacked along the thickness direction T thereof, which can reduce the space occupied by the guide assembly 30 in the length direction thereof.

[0063] As shown in Figs. 1 and 2, Figure 3 , Figure 4 and Figure 5 , the connection end of the leading guide rod 111 with the first assembly 2 and the connection end of the trailing guide rod 112 with the second assembly 3 are located on the same side of the guide assembly 30. In other embodiments, as shown in Figs. 1 and 2, Figure 2 , the connection end of the leading guide rod 111 with the first assembly 2 and the connection end of the trailing guide rod 112 with the second assembly 3 are located on the opposite side of the guide assembly 30.

[0064] As shown in Figs. 1 and 2, Figure 3 , Figure 4 and Figure 5 , the rotation axis of the leading guide rod 111 is coaxial with the rotation axis of the trailing guide rod 112.

[0065] In specific implementation, two adjacent guide rods can be connected through a first shaft component 200, as shown in Figs. 1 and 2, Figure 5 and Figure 6As shown in the figure, the end of each of the two adjacent guide rods is sleeved on the first shaft component 200 and can rotate around the first shaft component 200. The rotatable connection between the two adjacent guide rods can be realized through the first shaft component 200.

[0066] As shown in the figure, Figure 6 The first shaft component 200 includes a first connecting pin 210, an end cover 220 and a first fastener 230. The first connecting pin 210 includes a first shaft body 211 and a first end wall 212 connected to the first shaft body 211. The first shaft body 211 passes through the ends of the two adjacent guide rods, and the first end wall 212 abuts against one of the guide rods. The end cover 220 abuts against the other guide rod, and the first fastener 230 connects the first shaft body 211 and the end cover 220. Thus, the two adjacent guide rods can be connected, and both of the guide rods can rotate around the first shaft body 211, with coaxial rotation axes and good rotation effect.

[0067] As shown in the figure, Figure 6 A first bushing 240 is further sleeved between the guide rod and the first shaft body 211. Thus, the rotation of the guide rod is facilitated, and the guiding effect is improved.

[0068] In specific implementation, the first end guide rod 111 and the first assembly 2 are connected through a second shaft component 300, and the tail end guide rod 112 and the second assembly 3 are connected through the second shaft component 300, as shown in the figure, Figure 5 and Figure 7 The first end guide rod 111 and the tail end guide rod 112 are sleeved on the corresponding second shaft component 300 and can rotate around the second shaft component 300. The rotatable connection between the guide rod and the first assembly 2 and between the guide rod and the second assembly 3 can be realized through the second shaft component 300.

[0069] As shown in the figure, Figure 7 The second shaft component 300 includes a second connecting pin 310, a plug plate 320 and a second fastener 330. The second connecting pin 310 includes a second shaft body 311 and a second end wall 312 connected to the second shaft body 311. When the second shaft component 300 connects the first end guide rod 111 and the first assembly 2, the second shaft body 311 passes through the first end guide rod 111 and the first assembly 2 and extends out of the first assembly 2. The second end wall 312 abuts against the first end guide rod 111. The plug plate 320 is inserted into the part of the second shaft body 311 extending out of the first assembly 2 in the radial direction of the second shaft body 311 and is connected to the first assembly 2 through the second fastener 330.

[0070] When the second shaft component 300 is connected to the tail end guide rod 112 and the second component 3, the second shaft body 311 passes through the tail end guide rod 112 and the second component 3 and extends out of the second component 3, and the second end wall 312 abuts against the tail end guide rod 112; the insert plate 320 is inserted into the part of the second shaft body 311 that extends out of the second component 3 in the radial direction, and is connected to the second component 3 by the second fastener 330.

[0071] The second shaft component 300 for connecting the first guide rod 111 to the first component 2 and the second shaft component 3 for connecting the first guide rod 111 to the second component 3 can have the same structural configuration. The guide rod can be connected to the first component 2 or the second component 3 by a connecting pin. The insert plate 320 is inserted into the shaft body along the radial direction of the shaft body and is fixedly connected to the first component 2 or the second component 3, which can prevent the connecting pin from rotating and also prevent the connecting pin from moving in its axial direction.

[0072] The first fastener 230 and the second fastener 330 can be in the form of screws or other structural forms.

[0073] At least one second bushing 340 is fitted between the first guide rod 111 and the second shaft body 311, and between the tail guide rod 112 and the second shaft body 311. This facilitates the rotation of the guide rods, thereby improving the guiding effect. Figure 7 As shown, a second bushing 340 is fitted between each of the two guide rods and the second shaft body 311.

[0074] At least one spacer 400 is provided between two adjacent guide rods, between the first guide rod 111 and the first component 2, and between the tail guide rod 112 and the second component 3. This prevents damage to the guide rods, the first component 2 and the second component 3, and the spacer 400 is also easy to replace.

[0075] like Figure 5 and Figure 6 As shown, a spacer 400 is fitted onto the first shaft body 211 between two adjacent guide rods. The two axial end faces of the spacer 400 can respectively abut against the two guide rods, thereby preventing direct contact and wear between the two guide rods. Furthermore, a gap can be formed between the two guide rods, which is beneficial for their relative rotation. Figure 5 and Figure 7 As shown, the spacer 400 between the first guide rod 111 and the first component 2, and the spacer 400 between the tail guide rod 112 and the second component 3, can both be fitted onto the corresponding second shaft body 311. The two axial end faces of the spacer 400 can respectively abut against the corresponding guide rod and the corresponding component, thereby avoiding direct contact between the guide rod and the component. In specific implementations, the spacer 400 can be made of a relatively soft material, and the thickness of the spacer 400 can be configured according to requirements.

[0076] As shown in Figure 5 , the guide rod comprises a rod body 101 and a connecting disc 102, and the two ends of the rod body 101 are provided with the connecting disc 102, and the connecting disc 102 is provided with a counterbore. The connecting disc 102 can provide a more suitable connecting area to improve the stability of the connection, and the counterbore can facilitate the abutting and limiting of the above first end wall 212, second end wall 312 and end cover 220 while the shaft body passes through.

[0077] As shown in Figure 1 , Figure 3 and Figure 4 , the guide assembly 30 further comprises a limiting component 500 located below the guide rod for the guide rod to abut against; and the limiting component 500 is staggered with the connecting position of the guide rod and the first assembly 2 or the second assembly 3. The limiting component 500 can avoid the dead point caused by the guide rod descending too far, thereby causing the guide rod to be unable to expand with the relative movement of the first assembly 2 and the second assembly 3, affecting the guiding effect and the normal movement of the first assembly 2 and the second assembly 3. Specifically, as shown in Figure 1 , Figure 3 and Figure 4 , when the guide assembly 30 is arranged between the first assembly 2 and the second assembly 3, the connecting end of each guide rod of the guide assembly 30 is in a suspended state, and by arranging the limiting component 500, the guide assembly 30 can abut against, thereby avoiding the guide assembly 30 from descending to the dead point position.

[0078] As shown in Figure 4 , the limiting component 500 is arranged on both sides of the connecting position of the guide rod and the first assembly 2 or the second assembly 3. By arranging the limiting component 500 on both sides of the connecting position, the reliability of the guide can be further improved. Specifically, when the guide assembly 30 swings to one side of the connecting position of the first assembly 2 or the second assembly 3, or swings to the other side, there is a corresponding limiting component 500 for the guide assembly 30 to abut against.

[0079] The limiting component 500 is a limiting block extending below the guide rod from the side wall of the first assembly 2 or the second assembly 3. The limiting block has a simple structure and is easy to implement. As shown in Figure 3 and Figure 4 , the limiting block is connected to the bottom wall of the plate body of the first assembly 2. In other embodiments, as shown in Figure 1As shown, the limiting component 500 can also be a screw or bolt structure. In specific implementation, the extension distance of the limiting component 500 can be configured accordingly, but does not affect the normal relative movement of the first assembly 2 and the second assembly 3. For example, the limiting component 500 can extend below the first end guide rod 111, and the first end guide rod 111 abuts against the limiting component 500, thereby preventing the overall downward movement of the guide assembly 30. The limiting component 500 can also extend below the first end guide rod 111 and the second end guide rod 112.

[0080] As shown in Figures 3-7 , the guide assembly 30 includes two guide rods, i.e., a first guide rod 121 and a second guide rod 122, which are respectively the first end guide rod 111 and the second end guide rod 112. One end of the first guide rod 121 is rotatably connected to one end of the second guide rod 122, and the other end of the first guide rod 121 and the other end of the second guide rod 122 are rotatably connected to the first assembly 2 and the second assembly 3, respectively. By using two guide rods for guidance, the movement trajectory is more controllable, and the reliability of the guidance can be improved. In addition, when the guide assembly 30 has two guide rods, the thickness of the guide assembly 30 is thinner. When the guide assembly 30 is applied to the battery replacement device 1, the battery replacement device 1 occupies less space in the length direction and / or the width direction of the electric vehicle.

[0081] Embodiment 2

[0082] This embodiment provides a battery replacement device 1, as shown in Figure 8 and Figure 9 , the battery replacement device 1 includes a guide assembly 30 as in Embodiment 1 described above.

[0083] As shown in Figure 8 and Figure 9 , the battery replacement device 1 includes a device frame 10 and a battery replacement platform 20, and the first end guide rod 111 and the second end guide rod 112 are rotatably connected to the device frame 10 and the battery replacement platform 20, respectively. The guide assembly 30 can guide the relative movement between the battery replacement platform 20 and the device frame 10. Compared with other types of guide assemblies 30, the guide assembly 30 can have a longer guide stroke, thereby being able to adapt to the needs of various guide strokes.

[0084] As shown in Figure 8 and Figure 9 , the battery replacement platform 20 is located in a lifting space in the device frame 10, and the lifting direction UD of the battery replacement platform 20 relative to the device frame 10 is the vertical direction. Accordingly, the guide assembly 30 can also expand or contract in the vertical direction. As shown in Figure 3 and Figure 4 , the device frame 10 and the battery replacement platform 20 each have a plate body connected to the first end guide rod 111 and the second end guide rod 112.

[0085] The guiding assembly 30 is arranged between the equipment frame 10 and the battery replacing platform 20 on both sides of the battery replacing equipment 1 along the length direction of the vehicle and / or along the width direction of the vehicle. The guiding can be performed at multiple positions of the battery replacing equipment 1, and the guiding effect can be improved.

[0086] In a specific implementation, the guiding assembly 30 is preferably arranged around the equipment frame 10 and the battery replacing platform 20. As shown in Figure 8 and Figure 9 It is shown that the guiding assembly 30 is arranged between the equipment frame 10 and the battery replacing platform 20 on both sides of the electric vehicle along the length direction.

[0087] Two groups of guiding assemblies 30 are arranged between the equipment frame 10 and the battery replacing platform 20 on the same side of the battery replacing equipment 1, and the two groups of guiding assemblies 30 are symmetrically arranged or parallelly arranged. Multiple groups of guiding assemblies 30 are arranged on the same side of the battery replacing equipment 1, and the guiding effect on the side can be better. The multiple groups of guiding assemblies 30 are symmetrically arranged, and the internal force between the guiding assemblies 30 on the side is smaller, which is more conducive to guiding.

[0088] As shown in Figure 1 The two groups of guiding assemblies 30 are symmetrically arranged; as shown in Figure 9 The two groups of guiding assemblies 30 are parallelly arranged. It is worth noting that the guiding assembly 30 can also be rotated relative to the equipment frame 10 and the battery replacing platform 20 as a whole to change into symmetrically arranged.

[0089] Although the specific implementation of the present application is described above, those skilled in the art should understand that this is only an example, and the protection scope of the present application is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present application, and these changes and modifications all fall within the protection scope of the present application.
