Description

Technical Field

[0001] This utility model relates to the field of self-moving equipment technology, and in particular to a wheel mounting mechanism and a self-moving operation device. Background Technology

[0002] With the increasing popularity of self-propelled mobile work equipment, it has been involved in more aspects of people's lives, such as cleaning, mowing, and irrigation. However, because the wheels of self-propelled mobile work equipment rotate relative to the casing, foreign objects can easily enter the space between the wheels and the casing. Users need to clean the foreign objects in this space in a timely manner to prevent them from affecting the subsequent working effect of the self-propelled mobile work equipment. Therefore, there is a need for an installation structure that allows users to easily disassemble and install the wheels. Utility Model Content

[0003] In view of this, this application provides a wheel mounting mechanism and a self-moving working device, which improves the assembly efficiency of the wheel mounting mechanism by improving the wheel mounting mechanism.

[0004] A first aspect of this application provides a wheel mounting mechanism, which includes a housing, a mounting assembly, and a wheel axle.

[0015] As described above, the wheel mounting mechanism in this application can reduce the difficulty for users when assembling and disassembling the wheel mounting mechanism, thereby improving the user's assembly efficiency and the user experience of the product.

[0016] The second aspect of this application provides a self-moving work device, which includes the wheel mounting mechanism of the first aspect of this application.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] The following will refer to the appendices in the embodiments of this application. Figure 1 -Appendix Figure 9 The technical solutions in the embodiments of this application are described clearly and completely.

[0035] You can refer to this first. Figure 1 This application provides a self-moving work device 1000, which includes a wheel mounting mechanism 1. Specifically, see [reference needed]. Figures 2 to 9 The wheel mounting mechanism 1 includes a housing 10, a mounting assembly 11, and a wheel axle 12. The housing 10 can be made of plastic, rubber, or sheet metal, etc., and no specific restrictions are imposed here. The mounting assembly 11 is used to fix the wheel axle 12 to the housing 10. In other words, the wheel axle 12 is stably assembled to the housing 10 through the mounting assembly 11.

[0036] For reference Figure 2 and Figure 3 The housing 10 is provided with an installation channel 100, in which the mounting assembly 11 and the wheel axle 12 can enter and form a connection with the housing 10 in the installation channel 100, so that the wheel axle 12 is assembled on the housing 10.

[0037] The mounting assembly 11 is detachably connected to the housing 10, allowing the wheel axle 12 to switch between different connection states with the housing 10. The mounting assembly 11 is installed in the mounting channel 100 and includes an axle mounting base 110 and a pressure block 112. The axle mounting base 110 has an insertion channel 1101 and a first mounting through hole 1102 communicating with the insertion channel 1101. The pressure block 112 is disposed in the first mounting through hole 1102. The wheel axle 12 is inserted into the insertion channel 1101, and the pressure block 112 engages with the wheel axle 12 to fix the wheel axle 12 relative to the axle mounting base 110.

[0038] This application provides a mounting assembly 11 including an axle mounting base 110 and a pressure block 112. The wheel axle 12 and the housing 10 can be interconnected through the mounting assembly 11. In other words, the housing 10, the mounting assembly 11, and the wheel axle 12 are assembled to form the aforementioned wheel mounting mechanism 1. In this wheel mounting mechanism 1, after the wheel axle 12 is inserted into the insertion channel 1101 of the axle mounting base 110, the pressure block 112 presses the wheel axle 12 against the side wall of the insertion channel 1101, and the pressure block 112 engages and connects the wheel axle 12, thereby fixing the wheel axle 12 in the insertion channel 1101. Then, the assembled wheel axle 12 and the mounting assembly 11 are inserted into the mounting channel 100, so that the wheel axle 12 is assembled into the housing 10.

[0039] This application provides a wheel mounting mechanism 1 that facilitates the disassembly of the wheel axle 12. Specifically, since the wheel axle 12 is mounted in the mounting channel 100 of the housing 10 via the mounting component 11, and the mounting component 11 is detachably connected to the housing 10, when the self-propelled work equipment 1000 is in operation, if the wheel mounting mechanism 1 malfunctions due to foreign objects entering the mounting channel 100 of the housing 10, the user can remove the wheel axle 12 and the mounting component 11 together from the mounting channel 100 of the housing 10 to clean the foreign objects in the mounting channel 100. After the user has cleaned the foreign objects, the user can first assemble the mounting component 11 and the wheel axle 12, and then assemble the mounting component 11 and the wheel axle 12 as a whole into the housing 10, so that the wheel mounting mechanism 1 can continue to participate in the subsequent operation of the self-propelled work equipment 1000. Thus, when the user needs to clean the installation channel 100, the user can operate it himself to remove the wheel axle 12 from the installation channel 100 to clean the foreign objects in the installation channel 100. After the user has finished cleaning, the user can reassemble the wheel axle 12 into the housing 10 himself.

[0040] As described above, the wheel mounting mechanism 1 in this application can reduce the difficulty for users to assemble and disassemble the wheel mounting mechanism 1, thereby improving the user's assembly efficiency and the user experience of the product.

[0041] For reference Figures 3 to 6 Furthermore, the pressure block 112 is detachably connected to the wheel axle mounting base 110. The pressure block 112 is inserted into the first mounting through hole 1102 to engage with the wheel axle 12. Thus, when assembling the mounting assembly 11 and the wheel axle 12, the user can first insert the wheel axle 12 into the insertion channel 1101, and then insert the pressure block 112 into the first mounting through hole 1102, so that the pressure block 112 can engage with the wheel axle mounting base 110 and fix the wheel axle 12 relative to the wheel axle mounting base 110. After that, the user can insert the assembled mounting assembly 11 and the wheel axle 12 into the mounting channel 100, and through the connection between the mounting assembly 11 and the side wall of the mounting channel 100, the wheel axle 12 can be assembled to the housing 10. Since the pressure block 112 and the wheel axle mounting seat 110 are detachably connected, after the wheel axle 12 and the mounting assembly 11 are removed from the housing 10, the wheel axle 12, the pressure block 112 and the wheel axle mounting seat 110 can also be detached from each other, so that when the user needs to clean the foreign objects in the wheel mounting mechanism 1, the foreign objects in the insertion channel 1101 can be cleaned more thoroughly.

[0042] Please refer to this as well. Figures 2 to 6Optionally, the hole of the first mounting through hole 1102 extends in the radial direction of the wheel axle 12, and the insertion channel 1101 extends in the axial direction of the wheel axle 12. Therefore, during the assembly of the pressure block 112, the wheel axle 12 and the wheel axle mounting seat 110, the assembly direction between the wheel axle 12 and the wheel axle mounting seat 110 is perpendicular to the assembly direction between the pressure block 112 and the wheel axle mounting seat 110.

[0043] The wheel axle 12 is provided with a limiting groove 120 (e.g. Figure 2 and Figure 3 As shown, the limiting groove 120 is located in the insertion channel 1101, and the pressure block 112 is inserted into the limiting groove 120. Thus, in the axial direction of the wheel axle 12, due to the limiting effect between the pressure block 112 and the side wall of the limiting groove 120, the wheel axle 12 can be positioned by the pressure block 112 in the insertion channel 1101 of the wheel axle mounting seat 110. Therefore, when the mounting assembly 11 and the wheel axle 12 are assembled, the wheel axle 12 will not leave the insertion channel 1101 in the axial direction of the wheel axle 12.

[0044] Furthermore, such as Figure 2 and Figure 3 As shown, the limiting groove 120 is formed by the radial recess of the surface of the wheel axle 12. When the mounting assembly 11 and the wheel axle 12 are in the assembled state, the opposite sides of the pressure block 112 and the opposite side walls of the limiting groove 120 can abut against each other along the axial direction of the wheel axle 12. When the wheel mounting mechanism 1 is assembled, the pressure block 112 can restrain the relative movement of the wheel axle 12 relative to the housing 10 in the axial direction of the wheel axle 12 through the abutment action between the pressure block 112 and the side walls of the limiting groove 120, so that the wheel axle 12 can be stably located in the mounting channel 100 to ensure the structural stability of the wheel mounting mechanism 1.

[0045] In other embodiments, an annular rib is provided on the surface of the wheel axle 12 along the radial direction of the wheel axle 12. The annular rib and the wheel axle 12 together constrain to form a limiting groove 120. The limiting groove 120 can be a circular groove, a square groove, a trapezoidal groove, or other irregularly shaped grooves, etc., which are not subject to much constraint in this application.

[0046] Furthermore, the pressure block 112 and the limiting groove 120 are interference-fitted, or the pressure block 112 and at least one groove sidewall of the limiting groove 120 are bonded to each other to improve the connection strength between the pressure block 112 and the wheel axle 12. Thus, in the assembled state of the wheel mounting mechanism 1, the pressure block 112 and the wheel axle 12 can be stably connected, so that the wheel axle 12 can be stably located in the mounting channel 100.

[0047] In the rotatable direction of the wheel axle 12, due to the limiting effect between the pressure block 112 and the side wall of the limiting groove 120, the wheel axle 12 will not rotate relative to the wheel axle mounting seat 110. Thus, after the mounting assembly 11 and the wheel axle 12 are assembled, the wheel axle 12 will not rotate relative to the wheel axle mounting seat 110 in the rotatable direction of the wheel axle 12.

[0048] Please refer to the references. Figure 8 and Figure 9 Optionally, the wheel axle mounting base 110 is provided with a notch 1104, which is formed on the outer surface of the wheel axle mounting base 110. The housing 10 is also provided with a positioning protrusion 101, which protrudes from the inner wall of the mounting channel 100. The housing 10 is connected to the notch 1104 through the positioning protrusion 101 to position and connect the wheel axle mounting base 110. In this way, due to the mutual restraint between the positioning protrusion 101 and the side wall of the notch 1104, the wheel axle mounting base 110 will not rotate relative to the housing 10 in the mounting channel 100 along the rotatable direction of the wheel axle 12. Therefore, after the wheel mounting mechanism 1 is assembled, neither the mounting component 11 nor the wheel axle 12 will rotate relative to the housing 10, so that the mounting component 11 and the wheel axle 12 can be stably assembled in the mounting channel 100.

[0049] Furthermore, the notch 1104 can be an arc-shaped groove, a trapezoidal groove, a square groove, etc. The positioning protrusion 101 is interference-fitted with the notch 1104 to improve the connection strength between the housing 10 and the wheel axle mounting seat 110, so that the mounting component 11 and the wheel axle 12 can be stably assembled on the housing 10.

[0050] For further details, please refer to [link / reference]. Figure 9 Both the positioning protrusion 101 and the notch 1104 extend axially along the wheel axle 12, thus extending along the assembly direction of the wheel axle 12. The positioning protrusion 101 engages within the notch 1104 of the axle mounting seat 110. The engagement of the positioning protrusion 101 with the notch 1104 of the axle mounting seat 110 restricts the rotation of the axle mounting seat 110 relative to the housing 10, thereby ensuring that the mounting assembly 11 and the wheel axle 12 can be stably assembled in the mounting channel 100. The wheel axle mounting base 110 can move axially away from the positioning protrusion 101 to exit the mounting channel 100. Thus, when the user needs to remove the wheel axle 12 from the housing 10, the user can remove the mounting assembly 11 and the wheel axle 12 axially and perform subsequent operations. This design allows the user to conveniently and quickly assemble or disassemble the wheel axle 12 and the housing 10, facilitating self-maintenance and repair of the self-propelled work equipment 1000 (e.g., ...). Figure 1 ).

[0051] Furthermore, the mounting channel 100 is provided with a positioning protrusion 101 on the radial sidewall of the wheel axle 12, and the positioning protrusion 101 extends axially along the wheel axle 12; or, the mounting channel 100 is provided with a positioning protrusion 101 on the axial sidewall of the wheel axle 12, and the positioning protrusion 101 extends axially along the wheel axle 12.

[0052] Optionally, the wheel axle mounting seat 110 is perpendicular to the side wall of the wheel axle 12 along the axial direction to form a notch 1104, and the notch 1104 extends along the axial direction of the wheel axle 12. When the positioning protrusion 101 enters the notch 1104, the positioning protrusion 101 and the side wall of the notch 1104 form a mutual constraint. Thus, along the rotation direction of the wheel axle 12, the positioning protrusion 101 can constrain the wheel axle mounting seat 110, so that the wheel axle mounting seat 110 will not rotate relative to the housing 10. When the notch 1104 is formed on the side wall of the wheel axle mounting seat 110 perpendicular to the axial direction of the wheel axle 12, the positioning protrusion 101 can slide into the notch 1104 along the axial direction of the wheel axle 12. The side wall of the wheel axle mounting seat 110 perpendicular to the axial direction of the wheel axle 12 will not interfere with the positioning protrusion 101 entering the notch 1104. When the user assembles the mounting assembly 11 and the wheel axle 12, the user can directly insert the mounting assembly 11 and the wheel axle 12 into the mounting channel 100 along the axial direction of the wheel axle 12, so that the positioning protrusion 101 can be inserted into the notch 1104. In other words, when the wheel axle mounting seat 110 moves along the extension direction of the mounting channel 100 (which can also be regarded as the axial direction of the wheel axle 12), the positioning protrusion 101 can move relative to the wheel axle mounting seat 110 along the axial direction of the wheel axle 12 and enter the notch 1104, so that the wheel axle mounting seat 110 engages with the housing 10, thus facilitating user operation.

[0053] It should be noted that, since the extension direction of the mounting channel 100 in the wheel mounting mechanism 1 in the assembled state is parallel to the axial direction of the wheel axle 12, the extension direction of the mounting channel 100 can be regarded as the axial direction of the wheel axle 12.

[0054] In other embodiments, the wheel axle mounting seat 110 is perpendicular to the radial side wall of the wheel axle 12 and is recessed in the radial direction of the wheel axle 12 to form a notch 1104, and the notch 1104 extends in the axial direction of the wheel axle 12. During the process of assembling the mounting assembly 11 into the housing 10, the user can judge the assembly status between the wheel axle mounting seat 110 and the housing 10 by the "click" sound formed by the positioning protrusion 101 being inserted into the notch 1104.

[0055] For reference Figures 4 to 6 Optionally, the pressing block 112 (e.g.) Figure 5(As shown) It also includes a pressure block body 113 and a connecting leg 114. The connecting leg 114 is connected to the side of the pressure block body 113 and extends along the radial direction of the wheel axle 12. It should be understood that the radial direction of the wheel axle 12 is perpendicular to the axial direction of the wheel axle 12.

[0056] like Figure 6 As shown, the outer surface of the wheel axle mounting base 110 is also provided with a foot connecting groove 1105, and the connecting foot 114 is provided in the foot connecting groove 1105. In this way, through the mutual limiting effect between the connecting foot 114 and the side wall of the foot connecting groove 1105, after the pressure block 112 and the wheel axle mounting base 110 are assembled along the axial direction of the wheel axle 12, the two can maintain a stable connection state due to the mutual constraint effect. Thus, not only can the wheel axle 12 be stably constrained in the insertion channel 1101, but the structural stability of the mounting component 11 can also be guaranteed, so that the mounting component 11 and the wheel axle 12 can be stably located in the mounting channel 100 after assembly.

[0057] Furthermore, the connecting leg 114 is interconnected with the body of the pressure block 112 and forms an integral structure. In other words, the connecting leg 114 is integrally formed and connected with the body of the pressure block 112, or the connecting leg 114 is glued or pressed onto the side of the body of the pressure block 112 so that the pressure block 112 forms an integral structure.

[0058] Optionally, the pressure block 112 body is provided with at least one connecting leg 114 on each of the opposite sides of the wheel axle 12 radially. Correspondingly, the outer surface of the wheel axle mounting seat 110 is provided with at least one leg connecting groove 1105 on each of the opposite sides of the wheel axle 12 radially. One connecting leg 114 is connected to one leg connecting groove 1105. Thus, the pressure block 112 body and the opposite sides of the wheel axle mounting seat 110 can form a connection along the radial direction of the wheel axle 12. As a result, the force on the pressure block 112 body and the wheel axle mounting seat 110 can be relatively evenly distributed to each part of the solid structure of the pressure block 112 body and the wheel axle mounting seat 110, reducing the local stress intensity of the pressure block 112 body and the wheel axle mounting seat 110, and making the mutual constraint force between the pressure block 112 body and the wheel axle mounting seat 110 more evenly distributed to each part of the pressure block 112 body and the wheel axle mounting seat 110.

[0059] Alternatively, please refer back to the previous page. Figure 3The housing 10 is also provided with a second mounting through hole 102, which connects to the mounting channel 100. The mounting assembly 11 also includes a pressure cap 115, which is used to further constrain the movement of the mounting assembly 11 in the mounting channel 100. Specifically, the pressure cap 115 includes a stop portion 116, which is used to pass through the second mounting through hole 102 and engage with the wheel axle mounting seat 110, so that the wheel axle mounting seat 110 is fixed relative to the housing 10 in the axial direction of the wheel axle 12. Through the engagement connection between the stop portion 116 and the side wall of the second mounting through hole 102, and with the wheel axle mounting seat 110, the wheel axle mounting seat 110 can be stably connected to the housing 10 in the mounting channel 100 under the constraint of the pressure cap 115, and it is difficult for it to move relative to the housing 10. Thus, when the wheel mounting mechanism 1 is assembled, the wheel axle 12 and the mounting assembly 11 can be stably located in the mounting channel 100.

[0060] It should be noted that when the user needs to remove the wheel axle 12 from the housing 10, the pressure cover 115 must be removed first to release the constraint between the stop part 116 and the wheel axle mounting seat 110 so that the stop part 116 will no longer constrain the mounting assembly 11. Then, the mounting assembly 11 and the wheel axle 12 are pulled out along the extension direction of the mounting channel 100 to remove the wheel axle 12 from the housing 10.

[0061] Optionally, the cover 115 can be a plastic cover 115, a rubber cover 115, or a sheet metal cover 115. The cover 115 can cover the second mounting through hole 102. In this way, the cover 115 can not only restrict the degree of freedom of movement of the mounting assembly 11 in the mounting channel 100 by constraining the wheel axle mounting seat 110, but also cover the second mounting through hole 102 to isolate the mounting channel 100 from the external space of the housing 10. Thus, the cover 115 can prevent moisture, foreign objects, dust, etc. in the external space of the housing 10 from entering the mounting channel through the second mounting through hole 102. In the 100, the contamination of the installation channel 100 and the structures assembled in the installation channel 100 is eliminated, thereby maintaining the internal environment of the installation channel 100, reducing the frequency of user cleaning of the installation channel 100, and ensuring that the structures assembled in the installation channel 100 (such as wheel axle 12, installation components 11, etc.) are not disturbed by foreign objects and maintain a stable and good working condition. That is, while maintaining the working performance of the wheel installation mechanism 1, it can also further reduce the frequency of user cleaning of the installation channel 100, and improve the user's experience of using the self-moving operation equipment 1000.

[0062] Further reference is available. Figures 6 to 9 The axle mounting base 110 is provided with an abutment recess 1106, which is formed on the outer surface of the axle mounting base 110 and is spaced apart from the notch 1104. The abutment portion 116 (e.g.) Figure 9The stop portion 116 is provided in the abutment recess 1106, so that the stop portion 116 can be inserted into the abutment recess 1106. Through the limiting effect formed between the stop portion 116 and the side wall of the abutment recess 1106, the stop portion 116 can be engaged with the wheel axle mounting seat 110. Moreover, since the stop portion 116 can be inserted into the abutment recess 1106, that is, along the axial direction of the wheel axle 12, after the stop portion 116 is inserted into the abutment recess 1106, no additional connecting piece (not shown) is needed to achieve mutual restraint. Thus, the cover 115 can limit the connection between the housing 10 and the wheel axle mounting seat 110. When the wheel axle mounting seat 110 enters the mounting channel 100, the cover 115 can make the wheel axle mounting seat 110 stably located in the mounting channel 100, ensuring the structural stability of the wheel mounting mechanism 1 in the assembled state.

[0063] Optionally, the wheel mounting mechanism 1 further includes at least one connector (not shown) (not shown), wherein the connector (not shown) can be a screw, locating pin, etc. The connector (not shown) is used to connect the gland 115 and the housing 10. For details, please refer to [reference needed]. Figure 3 The pressure cap 115 has at least one connecting through hole 117, and a connector (not shown) is provided through the corresponding connecting through hole 117. The pressure cap 115 is connected to the housing 10 through the connector (not shown). In this way, the pressure cap 115 can be stably connected to the housing 10, so that the stop part 116 can stably engage with the wheel axle mounting seat 110, thereby improving the structural stability of the wheel mounting mechanism 1 in the assembled state.

[0064] Please continue to refer to this. Figure 3 Optionally, the housing 10 includes a connecting body 103 and at least two drive mounting parts 104. The two drive mounting parts 104 are connected to opposite sides of the connecting body 103, and the drive mounting parts 104 are provided with mounting channels 100 and second mounting through holes 102. Thus, at least one wheel can be mounted on opposite sides of the housing 10 to ensure the balance of the self-moving work equipment 1000 during movement.

[0065] The wheel mounting mechanism 1 includes at least two mounting components 11 and at least two wheel axles 12. The number of mounting components 11 and wheel axles 12 is set according to the number of drive mounting parts 104. One drive mounting part 104 is equipped with one mounting component 11 and one wheel axle 12.

[0066] The wheel mounting mechanism 1 also includes at least one pressure cover 115. The pressure cover 115 includes a crossover portion 118 and at least two abutment portions 116. The two abutment portions 116 are connected to opposite sides of a crossover portion 118. A second mounting through hole 102 is provided in one abutment portion 116 to engage with at least one wheel axle mounting seat 110. This achieves structural stability of the wheel mounting mechanism 1 after assembly.

[0067] Please continue to refer to this. Figure 3 Optionally, the bridging portion 118 is provided with a connecting through hole 117, and the connecting piece (not shown) passes through the connecting through hole 117. The bridging portion 118 is connected to the connecting body 103 through the connecting piece (not shown). In this way, while the cover 115, the wheel axle mounting seat 110 and the housing 10 are in a stable connection state along the axial direction of the wheel axle 12, the cover 115 and the housing 10 can form a connection relationship in the radial direction of the wheel axle 12 through the connecting piece (not shown), which further improves the structural stability of the wheel mounting mechanism 1 in the assembled state.

[0068] It should be noted that the connector (not shown) only needs to be installed corresponding to the connecting through hole 117. Specifically, the connecting through hole 117 can be provided at the abutment portion. In this case, the connector (not shown) can be connected to the drive mounting portion 104 by passing through the connecting through hole 117, or it can be connected to the wheel axle mounting seat 110 to ensure the structural stability of the wheel mounting mechanism 1 in the assembled state. However, when the connector (not shown) is connected to the wheel axle mounting seat 110 by passing through the connecting through hole 117, extra attention needs to be paid to the constraint effect of the connector (not shown) on the position of the mounting component 11 in the mounting channel 100 if the connector (not shown) penetrates the drive mounting portion 104 and enters the mounting channel 100. Alternatively, as in the above embodiment, the connecting through hole 117 can be provided at the above-mentioned bridging portion 118, and the connector (not shown) The connecting body 103 of the housing 10 is connected after the connecting through hole 117 is passed through, so as to make the housing 10 and the cover 115 stably connected. In short, the main purpose of the connector (not shown) is to further enable the cover 115 and the axle mounting seat 110, or the cover 115 and the housing 10 to form a constraint relationship in the radial direction along the wheel axle 12, on the basis of maintaining a stable limiting constraint effect along the axial direction of the wheel axle 12, so as to further improve the structural stability of the wheel mounting mechanism 1 in the assembled state. In short, as long as the connector (not shown) can realize the constraint relationship between the cover 115 and the axle mounting seat 110 or the housing 10 in the radial direction of the wheel axle 12, the connecting through hole 117 can be located at any position of the cover 115.

[0069] Optionally, the abutment portion 116 includes an abutment bottom wall and at least one abutment rib protruding from the abutment bottom wall toward the mounting channel 100. In the mounting channel 100, the abutment rib protrudes radially along the wheel axle 12. Thus, the abutment rib and the side wall of the abutment recess can form a mutual abutment action along the axial direction of the wheel axle 12. The pressure cover 115 can constrain the movement of the wheel axle mounting seat 110 along the axial direction of the wheel axle 12, thereby enabling the wheel axle mounting seat 110 to be stably assembled in the mounting channel 100, so that the wheel mounting mechanism 1 after assembly has good structural stability.
