Description

Technical Field

[0001] This application belongs to the field of construction machinery technology, specifically relating to an electric device. Background Technology

[0002] In the construction industry, electric actuators, such as pavers, are widely used due to their ease of operation and high efficiency. These electric actuators typically consist of an actuator body and a power supply mechanism, with the power supply mechanism installed in the actuator body and used to power the electronic components of the electric actuator.

[0003] However, the connection between the power supply mechanism and the device body of traditional electric actuators is not good, resulting in poor buffering effect of vibration and impact between the two. On the one hand, the vibration generated by the device body during operation is easily transmitted to the power supply mechanism, interfering with its normal operation. On the other hand, the external impact force on the power supply mechanism is also easily transmitted to the device body, causing damage to the device body, thus resulting in a high failure rate of electric actuators. Summary of the Invention

[0004] The purpose of this application is to provide an electric device that can solve the problem of high failure rate of electric devices in related technologies.

[0005] This application provides an electric device, including: device body; The device includes a power supply mechanism, a first buffer, and a second buffer. The second buffer is arranged circumferentially along the first buffer. The power supply mechanism is located on one side of the device body and is connected to the device body through the first buffer and the second buffer, respectively.

[0006] In related technologies, the power supply mechanism is rigidly connected to the device body, and no buffer is set between the two. This results in poor buffering effect of vibration and impact force between the two, which in turn leads to a high failure rate of the electric device.

[0007] In this embodiment, the second buffer is arranged circumferentially along the first buffer, and the power supply mechanism is located on one side of the device body. The power supply mechanism is connected to the device body through both the first and second buffers. In this way, the first and second buffers provide dual buffering, both buffering the vibration and impact forces between the power supply mechanism and the device body. This reduces the transmission of vibration and impact forces between them, improves the buffering effect, and thus reduces the failure rate of the electric device. Attached Figure Description

Detailed Implementation

[0010] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0011] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0012] The electric device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0013] Please refer to Figures 1 to 14 As shown, this application embodiment provides an electric device, including a device body 100, a power supply mechanism 200, a first buffer 300, and a second buffer 400. Exemplarily, the electric device is a paving machine, which can absorb or release building materials such as tiles and is used to lay building materials.

[0014] Specifically, the device body 100 is the main part of the electric device, serving as the mounting base for other components of the electric device. The second buffer 400 is arranged circumferentially along the first buffer 300. The power supply mechanism 200 is located on one side of the device body 100, and the power supply mechanism 200 is connected to the device body 100 through the first buffer 300 and the second buffer 400 respectively. That is, the first buffer 300 and the second buffer 400 each correspond to a buffer path. A portion of the vibration and impact force between the power supply mechanism 200 and the device body 100 is buffered by the first buffer 300, and another portion of the vibration and impact force is buffered by the second buffer 400.

[0015] In related technologies, the power supply mechanism 200 is rigidly connected to the device body 100, and no buffer is provided between the two. This results in poor buffering effect of vibration and impact between the two, which in turn leads to a high failure rate of the electric device.

[0016] In this embodiment, the second buffer 400 is arranged circumferentially along the first buffer 300, and the power supply mechanism 200 is located on one side of the device body 100. The power supply mechanism 200 is connected to the device body 100 through the first buffer 300 and the second buffer 400. In this way, the first buffer 300 and the second buffer 400 provide dual buffering, both buffering the vibration and impact forces between the power supply mechanism 200 and the device body 100. This reduces the mutual transmission of vibration and impact forces between them, improves the buffering effect, and thus reduces the failure rate of the electric device.

[0017] Furthermore, the second buffer 400 is arranged circumferentially along the first buffer 300, and the second buffer 400 occupies the space circumferentially of the first buffer 300 in a concentrated manner. This reduces the space occupied in other areas and helps to improve the compactness of the electric device.

[0018] By adopting the solution of this embodiment, the first buffer 300 and the second buffer 400 can effectively buffer the vibration generated during the operation of the device body 100, thereby reducing the vibration transmitted to the power supply mechanism 200 and extending the service life of the power supply mechanism 200.

[0019] In another embodiment, reference Figure 8 and Figure 9 As shown, the second buffer 400 is an annular member and is fitted around the first buffer 300, meaning the second buffer 400 is arranged circumferentially around the first buffer 300. The device body 100 and the power supply mechanism 200 are arranged sequentially along the axial direction of the second buffer 400. Specifically, the arrangement direction of the device body 100 and the power supply mechanism 200 is approximately as follows: Figure 1 The direction indicated by arrow A in the diagram. In this configuration, the second buffer 400 achieves 360-degree circumferential buffering of the first buffer 300, thus improving the buffering effect of vibration and impact between the device body 100 and the power supply mechanism 200. At the same time, the annular component can evenly distribute the force, thereby reducing the possibility of damage to the second buffer 400 due to excessive local force.

[0020] For example, the second buffer 400 is made entirely of an elastic material.

[0021] In other embodiments, the second buffer 400 may also be a non-annular component, meaning it is not a closed structure in the circumferential direction of the first buffer 300, but extends only along the circumferential direction of the first buffer 300. In this configuration, the second buffer 400 may be, for example, an arc-shaped component. Additionally, the second buffer 400 may also include at least two buffer sub-parts, each buffer sub-part arranged at intervals along the circumferential direction of the first buffer 300.

[0022] In another embodiment, reference Figures 3 to 5 As shown, the power supply mechanism 200 has a first mating part 230, and the second buffer 400 is nested with the first mating part 230. One of the two has a first annular protrusion 231 in its circumferential direction, and the other has a first annular groove 410 in its circumferential direction. The first annular protrusion 231 and the first annular groove 410 are engaged. In this configuration, the power supply mechanism 200 and the second buffer 400 are engaged through the first mating part 230. The engagement method basically does not require tools. The first annular protrusion 231 is directly engaged into the first annular groove 410, which realizes the assembly of the power supply mechanism 200 and the second buffer 400, thereby reducing the assembly difficulty.

[0023] Optionally, the second buffer 400 is fitted outside the first mating part 230, meaning that the second buffer 400 does not occupy much space within the first mating part 230, thus facilitating the arrangement of other components within the first mating part 230. Of course, a portion of the second buffer 400 can also extend into the first mating part 230, depending on the actual design requirements.

[0024] For example, the first mating part 230 is provided with a first annular protrusion 231, and correspondingly, the second buffer member 400 is provided with a first annular groove 410. It should be noted that the positions of the first annular protrusion 231 and the first annular groove 410 can also be interchanged, and this is not limited in the embodiments of this application.

[0025] In other embodiments, the power supply mechanism 200 and the second buffer 400 may also be connected via the first threaded member.

[0026] In one alternative embodiment, reference is made to... Figure 1 and Figure 14 As shown, the power supply mechanism 200 includes a power supply body 210 and a mounting base 220. The power supply body 210 is, for example, a battery pack. The mounting base 220 has the first mating part 230 mentioned above. One of the power supply body 210 and the mounting base 220 has a plug-in part, and the other has a plug-in groove 222. The plug-in part and the plug-in groove 222 are plugged into each other along the height direction of the electric device, which is approximately [missing information]. Figure 1 The direction indicated by arrow B in the diagram. Meanwhile, refer to... Figure 10As shown, the power supply body 210 is provided with a snap-fit ​​part 211. When the plug-in part is inserted into place, the snap-fit ​​part 211 engages with the mounting base 220, thereby achieving a detachable connection between the power supply body 210 and the mounting base 220. This detachable connection method allows for the replacement of the power supply body 210 alone when it is damaged, without needing to replace the mounting base 220, thus reducing waste. Furthermore, since there is no need to replace the mounting base 220, replacing the power supply body 210 will not significantly affect the snap-fit ​​engagement between the first mating part 230 and the second buffer member 400, thereby reducing the maintenance difficulty of the electric device.

[0027] In another embodiment, reference Figure 6 As shown, the device body 100 is provided with a second mating part 110, and the second buffer member 400 is nested with the second mating part 110. One of the two is provided with a second annular protrusion 111 in the circumferential direction, and the other is provided with a second annular groove 420 in the circumferential direction. The second annular protrusion 111 and the second annular groove 420 are engaged. In this configuration, the device body 100 and the second buffer member 400 are engaged through the second mating part 110. As mentioned above, the engagement method basically does not require tools. The second annular protrusion 111 is directly engaged in the second annular groove 420, which realizes the assembly of the device body 100 and the second buffer member 400, thereby reducing the assembly difficulty.

[0028] Optionally, the second buffer 400 is sleeved outside the second mating part 110. The placement of the second buffer 400 does not occupy much space within the second mating part 110, which facilitates the arrangement of other components within the second mating part 110. Alternatively, a portion of the second buffer 400 may extend into the second mating part 110, depending on the actual design requirements.

[0029] For example, the second mating part 110 is provided with a second annular protrusion 111, and correspondingly, the second buffer member 400 is provided with a second annular groove 420. Of course, the positions of the second annular protrusion 111 and the second annular groove 420 can also be interchanged, and this is not limited in the embodiments of this application.

[0030] In other embodiments, the power supply mechanism 200 and the second buffer 400 may also be connected via a second threaded connection.

[0031] In another embodiment, reference Figures 4 to 7As shown, at least a portion of the side of the first annular rib 231 near the second annular rib 111 is inclined, forming a first guide slope 2311. The first guide slope 2311 can guide and cooperate with the second buffer member 400. At least a portion of the side of the second annular rib 111 near the first annular rib 231 is inclined, forming a second guide slope 1111. The second guide slope 1111 can cooperate with the second buffer member 400. Along the direction away from the axis of the second buffer member 400, the distance between the first guide slope 2311 and the second guide slope 1111 gradually increases, and the direction away from the axis of the second buffer member 400 is approximately... Figure 9 The direction indicated by the arrow C in the diagram.

[0032] In this embodiment, during the axial assembly of the first mating part 230 and the second buffer member 400, the first guide slope 2311 guides and engages with the second buffer member 400, causing local deformation of the second buffer member 400. This facilitates the placement of the first annular protrusion 231 within the first annular groove 410, reducing the assembly difficulty. Similarly, during the axial assembly of the second mating part 110 and the second buffer member 400, the second guide slope 1111 guides and engages with the second buffer member 400, causing local deformation of the second buffer member 400. This facilitates the placement of the second annular protrusion 111 within the second annular groove 420, reducing the assembly difficulty.

[0033] Optionally, refer to Figure 9 As shown, the shape of the first annular groove 410 is adapted to the shape of the first annular rib 231 to increase the mating area between the two, thereby improving the reliability of the mating between the first mating part 230 and the second buffer member 400. The shape of the second annular groove 420 is adapted to the shape of the second annular rib 111 to increase the mating area between the two, thereby improving the reliability of the mating between the second mating part 110 and the second buffer member 400.

[0034] In other embodiments, the first guide slope 2311 may be omitted. In this case, the plane containing the side of the first annular rib 231 closest to the second annular rib 111 is, for example, perpendicular to the axial direction of the second buffer member 400. Similarly, the second guide slope 1111 may be omitted. In this case, the plane containing the side of the first annular rib 231 closest to the second annular rib 111 is, for example, perpendicular to the axial direction of the second buffer member 400.

[0035] In another embodiment, the first mating part 230 and the second mating part 110 are mutually limitingly fitted in both the height direction and the first direction of the device body 100. The arrangement direction of the device body 100 and the power supply mechanism 200, the height direction of the device body 100, and the first direction intersect each other. Specifically, the arrangement direction of the device body 100 and the power supply mechanism 200 is perpendicular to the height direction of the device body 100, and both are perpendicular to the first direction. The height direction of the device body 100 is the same as the height direction of the electric device, and the first direction is approximately... Figure 4 The direction indicated by the arrow line D in the diagram.

[0036] In this embodiment, the first mating part 230 and the second mating part 110 are mutually restrictive in both the height direction and the first direction of the device body 100. This restricts the movement of both parts in these directions, making misalignment less likely. Consequently, the force between the second buffer member 400 and the first mating part 230 and the second mating part 110 is mainly concentrated in the axial direction of the second buffer member 400, resulting in less shear force on the second buffer member 400 in the height direction and the first direction. This helps extend the service life of the second buffer member 400.

[0037] Optionally, refer to Figure 4 As shown, the first mating part 230 is provided with at least two second limiting sub-parts 232, each of which engages with the second mating part 110 in a first direction. In this arrangement, at least two second limiting sub-parts 232 engage with the second mating part 110, resulting in a larger mating area between the first mating part 230 and the second mating part 110 in the first direction, thereby improving the reliability of their engagement.

[0038] Further, refer to Figure 3 and Figure 4 As shown, at least two second limiting sub-parts 232 include a first sub-part 232a and a second sub-part 232b. The first sub-part 232a and the second sub-part 232b are respectively provided on opposite sides of the second mating part 110. In this way, the first mating part 230 and the second mating part 110 are both limited and engaged in the direction from the first sub-part 232a to the second sub-part 232b and in the direction from the second sub-part 232b to the first sub-part 232a, thereby improving their stability.

[0039] Furthermore, in the arrangement direction of the device body 100 and the power supply mechanism 200, the second limiting sub-part 232 can be limited to cooperate with the second mating part 110 to limit the relative movement of the first mating part 230 and the second mating part 110 in that direction, thereby preventing the second buffer 400 from being overstretched or overcompressed, which helps to extend the service life of the second buffer 400.

[0040] Optionally, refer to Figure 3 and Figure 6 As shown, the second mating part 110 is provided with a first limiting sub-part 112, at least a portion of which extends into the first mating part 230. The bottom end of the device body 100 is located on a first plane, and the first limiting sub-part 112 is used to restrict the power supply mechanism 200 from moving towards the first plane. In this configuration, when the direction of gravity is the same as the height direction of the device body 100, the first limiting sub-part 112 can prevent the power supply mechanism 200 from moving towards the first plane under the action of gravity, thereby reliably maintaining the power supply mechanism 200 in the corresponding position.

[0041] In other embodiments, the first mating part 230 and the second mating part 110 may not have a limiting mating relationship in the height direction and / or the first direction of the device body 100.

[0042] In another embodiment, reference Figures 10 to 13 As shown, the first buffer 300 includes a first buffer portion 310 and a second buffer portion 320 connected in sequence. At least a portion of the first buffer portion 310 extends into and is connected to the power supply mechanism 200; and / or, at least a portion of the second buffer portion 320 extends into and is connected to the device body 100.

[0043] In this embodiment, when at least a portion of the first buffer portion 310 extends into the power supply mechanism 200, at least a portion of the first buffer portion 310 is hidden within the power supply mechanism 200, thus reducing the space occupied outside the power supply mechanism 200 and improving the compactness of the electric device.

[0044] Similarly, when at least a portion of the second buffer portion 320 extends into the device body 100, at least a portion of the second buffer portion 320 is hidden within the device body 100, thereby reducing the space occupied outside the device body 100 and improving the compactness of the electric device.

[0045] In other embodiments, the first buffer 310 may also be located outside the power supply mechanism 200, while the second buffer 320 is located outside the device body 100.

[0046] In another embodiment, reference Figure 5 and Figure 10As shown, the power supply mechanism 200 has a slot 240, and the first buffer part 310 is located in the slot 240 and engages with the slot wall of the slot 240. This method of engaging the first buffer part 310 with the slot wall of the slot 240 makes the connection between the first buffer part 310 and the power supply mechanism 200 less susceptible to interference from external magnetic fields, resulting in better connection reliability.

[0047] Optionally, refer to Figure 10 As shown, the power supply mechanism 200 includes the mounting base 220 mentioned above. The mounting base 220 includes a first base body 221 and a second base body that are separately disposed in a first direction and detachably connected. A portion of the slot 240 is disposed in the first base body 221, and the other portion is disposed in the second base body. With this arrangement, the first buffer part 310 is easy to disassemble and assemble when the first base body 221 and the second base body are not assembled, thereby reducing the difficulty of replacing and maintaining the first buffer part 300.

[0048] Further, refer to Figure 10 As shown, one of the first base 221 and the second base is provided with a positioning protrusion 223, and the other is provided with a positioning groove. The positioning protrusion 223 and the positioning groove are positioned and engaged. With this configuration, there is basically no need for additional positioning procedures. Simply placing the positioning protrusion 223 in the positioning groove is sufficient to basically position the relative positions of the first base 221 and the second base, thereby reducing the assembly difficulty of the first base 221 and the second base.

[0049] In other embodiments, the first buffer portion 310 may also magnetically engage with the power supply mechanism 200.

[0050] In one optional embodiment, the device body 100 is provided with a receiving groove, and the second buffer part 320 is located in the receiving groove and engages with the groove wall of the receiving groove.

[0051] In another embodiment, the electric device further includes a connecting shaft 500, at least a portion of which passes through a second buffer portion 320, which is connected to the device body 100 via the connecting shaft 500.

[0052] Compared to the previous method of engaging the second buffer part 320 with the wall of the receiving groove, the present embodiment uses a connecting shaft 500 to connect the second buffer part 320 with the device body 100, which reduces the shape requirements of the second buffer part 320 and helps to reduce the processing difficulty of the second buffer part 320.

[0053] In one alternative embodiment, reference is made to... Figure 7 and Figure 13As shown, the axial direction of the connecting shaft 500 is the same as that of the first direction. The device body 100 includes a first sub-housing 101 and a second sub-housing 102 that are separately disposed and detachably connected in the first direction. Both the first sub-housing 101 and the second sub-housing 102 are provided with mounting grooves 120. Both ends of the connecting shaft 500 are fitted with buffer sleeves 510, and the two buffer sleeves 510 are respectively disposed in the two mounting grooves 120. The buffer sleeves 510 can buffer the force between the two ends of the connecting shaft 500 and the groove walls of the two mounting grooves 120, thereby extending the service life of the device body 100 and the connecting shaft 500.

[0054] In other embodiments, the end of the connecting shaft 500 may not have a buffer sleeve 510.

[0055] In another embodiment, there are at least two connecting shafts 500, the axes of each connecting shaft 500 are parallel to each other, and each connecting shaft 500 is arranged sequentially along the height direction of the device body 100. The arrangement direction of the device body 100 and the power supply mechanism 200, the height direction of the device body 100 and the axis of the connecting shaft 500 intersect each other, specifically, for example, they are perpendicular to each other.

[0056] In this embodiment, the second buffer section 320 is connected to the device body 100 via at least two connecting shafts 500. With the combined action of the at least two connecting shafts 500, the connection reliability between the second buffer section 320 and the device body 100 is good. Furthermore, the force on the second buffer section 320 is mainly concentrated in the height direction of the device body 100. By arranging the connecting shafts 500 sequentially along the height direction of the device body 100, each connecting shaft 500 can share the force exerted by the second buffer section 320 in the height direction of the device body 100, which helps to extend the service life of the connecting shafts 500.

[0057] In other embodiments, the number of connecting shafts 500 may also be one. Additionally, the arrangement direction of each connecting shaft 500 may intersect with the height direction of the device body 100.

[0058] In another embodiment, reference Figure 12 As shown, the second buffer portion 320 is an elastic portion. The second buffer portion 320 is provided with an opening 340 for accommodating the connecting shaft 500. At least two deformation compensation grooves 341 are arranged circumferentially on the wall of the opening 340, and the wall of the opening 340 is divided by the deformation compensation grooves 341 to form at least two elastic sub-parts 342 arranged circumferentially.

[0059] In this embodiment, the deformation compensation groove 341 provides deformation space for the elastic sub-part 342, making it easier for the elastic sub-part 342 to undergo elastic deformation and avoid the connecting shaft 500 during the process of the connecting shaft 500 passing through the opening 340. This reduces the assembly difficulty of the connecting shaft 500 and the second buffer part 320.

[0060] For example, the first elastic element is an elastic element in its entirety.

[0061] In other embodiments, the hole wall of the opening 340 may not have the deformation compensation groove 341, that is, the hole wall of the opening 340 is a continuous annular structure in the circumferential direction of the opening 340.

[0062] In another embodiment, the first buffer 300 includes a first buffer portion 310 and a second buffer portion 320. The power supply mechanism 200 is connected to the device body 100 sequentially through the first buffer portion 310 and the second buffer portion 320. At least a portion of the bottom end of the device body 100 is located on a first plane. The first buffer portion 310 is offset relative to the second buffer portion 320 in a direction away from the first plane, and the direction away from the first plane is approximately... Figure 12 The direction indicated by arrow E in the diagram. With this configuration, even if the power supply mechanism 200 moves slightly toward the first plane, it can still maintain a certain distance from the first plane, which helps to reduce interference between the power supply mechanism 200 and other components.

[0063] In actual use, refer to Figure 2 As shown, the bottom end of the device body 100 is provided with an adsorption member 600. Part of the adsorption member 600 is located on the first plane. The adsorption member 600 is used to adsorb or release building materials such as tiles mentioned above. By making the first buffer part 310 offset relative to the second buffer part 320 in a direction away from the first plane, interference between the power supply mechanism 200 and building materials such as tiles can be prevented.

[0064] Optionally, refer to Figures 10 to 13 As shown, in the height direction of the device body 100, the portions of the first buffer portion 310 and the second buffer portion 320 that are offset from each other are used to limit the engagement with the groove wall of the slot 240 mentioned above. Meanwhile, in the first direction, both ends of the first buffer portion 310 protrude from the second buffer portion 320, and both engage with the groove wall of the slot 240. With this configuration, the orthographic projection of the first buffer member 300 along the height direction of the device body 100 is approximately T-shaped.

[0065] In other embodiments, in the height direction of the device body 100, the two ends of the first buffer portion 310 may be flush with the two ends of the second buffer portion 320 respectively.

[0066] In another embodiment, reference Figure 13 As shown, the first buffer member 300 is provided with a through groove 330, which is a strip-shaped groove. The length direction of the through groove 330 is inclined relative to the arrangement direction of the power supply mechanism 200 and the device body 100. In this configuration, the through groove 330 can directionally adjust the local flexibility of the first buffer member 300, which helps to improve the buffering effect of the first buffer member 300 and optimize the stress on the first buffer member 300, thus extending the service life of the first buffer member 300.

[0067] Optionally, there are at least two through slots 330, and each through slot 330 is arranged sequentially along the height direction of the device body 100, so as to further improve the buffering effect of the first buffer 300 and better optimize the force on the first buffer 300.

[0068] Optionally, the first buffer 300 includes the first buffer portion 310 and the second buffer portion 320 mentioned above. The through groove 330 is disposed in the second buffer portion 320, and the end of the through groove 330 near the first buffer portion 310 is offset in a direction away from the first plane mentioned above relative to the end away from the first buffer portion 310, so as to meet the corresponding buffering and force requirements.

[0069] In other embodiments, the first buffer 300 may not have the through groove 330. Alternatively, the first buffer 300 may have the through groove 330, but the length direction of the through groove 330 is the same as the arrangement direction of the power supply mechanism 200 and the device body 100.

[0070] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
