[0061] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0062] Example

[0063] Figure 1Schematic diagram of the structure of a 3D printer 1000 in one embodiment of the present application; Figure 2 for Figure 1 A perspective view of the 3D printer base 100 in the illustrated embodiment.

[0064] See also Figure 1 , an embodiment of the present application provides a 3D printer 1000 , including a 3D printer base 100 .

[0065] For ease of understanding, the first direction X, the second direction Y, and the third direction Z are introduced for description in the embodiments of the present application. The first direction X, the second direction Y, and the third direction Z are three non-parallel directions in the spatial coordinate system. In subsequent embodiments, the first direction X, the second direction Y, and the third direction Z are taken as examples of three mutually perpendicular reference directions in the three-dimensional Cartesian coordinate system. The directions shown in the embodiments of the present application are used to help understand the relative positional relationship of each component, but do not limit their specific directions.

[0066] In some embodiments, as Figure 1 As shown, the 3D printer 1000 also includes a 3D printer support 200, which can be a gantry or other support structure. The 3D printer support 200 is connected to the 3D printer base 100 and includes two columns 201 on either side and a crossbeam 202 connected to the tops of the columns 201. An X-axis drive mechanism 300 is connected to the columns 201 on either side and can be driven to rise or fall relative to the columns 201 in a third direction Z. The nozzle assembly 400 is mounted on the 3D printer support 200 via the X-axis drive mechanism 300.

[0067] In some embodiments, a forming platform 101 is provided on the 3D printer base 100 . The forming platform 101 is used to carry and form the consumable material extruded by the nozzle assembly 400 , and can be driven to move along the second direction Y relative to the housing 10 of the 3D printer base 100 .

[0068] Figure 3 for Figure 1 A schematic diagram of a portion of the structure of the 3D printer base 100 in the illustrated embodiment; Figure 4 for Figure 3 A partial enlarged view of point A of the 3D printer base 100 in the illustrated embodiment.

[0069] See also Figures 2 to 4The 3D printer base 100 in this embodiment includes a housing 10 and multiple functional components 20. The housing 10 defines a housing cavity 10a, within which the multiple functional components 20 are mounted. The multiple functional components 20 are connected by wiring harnesses (not shown). A first wiring structure 30 is provided between at least two functional components 20. The first wiring structure 30 includes a first wiring groove 30a. A wiring harness connected to one functional component 20 passes through the first wiring groove 30a and is connected to another functional component 20.

[0070] It can be understood that the above-mentioned 3D printer base 100, by providing the first wiring structure 30, allows at least one wiring harness connected between different functional components 20 to pass through the first wiring groove 30a, thereby making the wiring harnesses connected between different functional components 20 more orderly, reducing the risk of short circuit caused by the entanglement of different wiring harnesses, avoiding waste of space, and facilitating the search and inspection of the target wiring harness during subsequent maintenance.

[0071] In some embodiments, as Figure 4 As shown, the first wiring structure 30 includes a limiting portion 31 and multiple wiring portions 32. The multiple wiring portions 32 are arranged relative to each other and at intervals to define a first wiring trough 30a between the multiple wiring portions 32. The limiting portion 31 is connected to the side of the wiring portion 32 away from the bottom of the first wiring trough 30a and is arranged relative to the bottom of the first wiring trough 30a. The limiting portion 31 is used to limit the wiring harness within the first wiring trough 30a. In this way, by setting the wiring portion 32, the arrangement direction of the wiring harness within the first wiring trough 30a is constrained, and the position of the wiring harness within the first wiring trough 30a is fixed, making the wiring harness more orderly; by setting the limiting portion 31, the wiring harness is confined within the first wiring trough 30a to prevent the wiring harness from escaping from the first wiring trough 30a. In addition, the distance width between the wiring portions 32 and the length of the wiring portions 32 can be adaptively adjusted according to actual needs and are not specifically limited here.

[0072] In this embodiment, there are two wiring portions 32 , and the two wiring portions 32 are disposed opposite to each other and spaced apart, so as to define a first wiring groove 30 a between the two wiring portions 32 .

[0073] Optionally, combined Figure 3 and Figure 4 As shown, the two wiring portions 32 are separated from the side of the cavity wall of the accommodating cavity 10a to form a notch of the first wiring groove 30a, which is convenient for operation and installation of the wiring harness. For example, the two wiring portions 32 are separated from the side of the top wall 11 of the accommodating cavity 10a to form a notch of the first wiring groove 30a, wherein the top wall 11 of the accommodating cavity 10a refers to the accommodating cavity 10a close to the molding platform 101 along the third direction Z (see FIG. Figure 2In this way, the first wiring groove 30a is close to the top wall 11 of the accommodating cavity 10a, which facilitates the connection of the wiring harness passing through the first wiring groove 30a with the functional component 20 in the accommodating cavity 10a.

[0074] In some embodiments, as Figure 4 As shown, there are multiple limiting portions 31, spaced apart along the extension direction of the first wiring trough 30a, and each of the limiting portions 31 is connected to the two wiring portions 32. This further enhances the guiding and limiting function of the first wiring trough 30a for the wiring harness, as the first wiring trough 30a has a certain length along its extension direction. Furthermore, the multiple limiting portions 31 are provided to limit the wiring harness at different positions within the first wiring trough 30a, ensuring that the wiring harness is routed along the extension direction of the first wiring trough 30a. The multiple limiting portions 31 are connected to the two wiring portions 32, ensuring that the wiring harness does not escape from the first wiring trough 30a.

[0075] In this embodiment, there are three limiting portions 31 , which are spaced apart along the extension direction of the first wiring groove 30 a , and two limiting portions 31 are connected to one of the wiring portions 32 , while the remaining limiting portion 31 is connected to the other wiring portion 32 .

[0076] In some embodiments, as Figure 3 and Figure 4 As shown, the accommodating chamber 10a includes a first accommodating chamber 10a1 and a second accommodating chamber 10a2, which are respectively arranged near opposite sides of the housing 10 along the first direction X. The two functional components 20 are respectively a first functional component 21 and a second functional component 22, with the first functional component 21 being arranged in the first accommodating chamber 10a1 and the second functional component 22 being arranged in the second accommodating chamber 10a2. A first wiring trough 30a connects the first accommodating chamber 10a1 and the second accommodating chamber 10a2, and the first wiring trough 30a extends along the first direction X. In this way, one end of the first wiring trough 30a is close to the first accommodating chamber 10a1, and the other end of the first wiring trough 30a is close to the second accommodating chamber 10a2, thereby facilitating the wiring harness connected to the first functional component 21 to pass through the first wiring trough 30a and then connect to the second functional component 22.

[0077] For ease of understanding, the following Figure 3 Taking an example to illustrate, one side of the shell 10 along the first direction X is the left side of the shell 10, and the other side of the shell 10 along the first direction X is the right side of the shell 10. The first accommodating cavity 10a1 is arranged close to the left side of the shell 10, and the second accommodating cavity 10a2 is arranged close to the right side of the shell 10.

[0078] Alternatively, as Figure 4As shown, the two routing portions 32 are opposite and spaced apart along the second direction Y, the routing portion 32 extends along the first direction X, and the plurality of limiting portions 31 are spaced apart along the first direction X, so that the wiring harness passing through the first routing groove 30a can be routed more neatly along the first direction X.

[0079] In some embodiments, as Figure 3 As shown, the first functional component 21 is a mainboard 21b, and the second functional component 22 is a power supply 22b. The power supply 22b is used to convert an externally input AC voltage into a DC voltage to power the mainboard 21b. Optionally, a power supply interface 70 is provided in the accommodating cavity 10a. The power supply 22b is electrically connected to the power supply interface 70 and is used to convert the AC voltage input by the power supply interface 70 into a DC voltage and input it into the mainboard 21b.

[0080] In some embodiments, as Figure 3 and Figure 4 As shown, the 3D printer base 100 also includes a guide rail 40 and a bracket 50. At least a portion of the guide rail 40 is located within the accommodating cavity 10a, with a first accommodating cavity 10a1 and a second accommodating cavity 10a2 located on either side of the guide rail 40 along the first direction X. The bracket 50 is disposed within the accommodating cavity 10a and mounted outside the guide rail 40. The bracket 50 is provided with a first wiring structure 30. By positioning at least a portion of the guide rail 40 within the accommodating cavity 10a, the structure of the 3D printer base 100 is made more compact. By positioning the bracket 50 outside the guide rail 40, the bracket 50 is kept out of the way. Furthermore, by mounting the first wiring structure 30 on the bracket 50, the space in the accommodating cavity 10a is more efficiently utilized.

[0081] For ease of understanding, the following Figure 3 Taking an example to illustrate, one side of the guide rail 40 along the first direction X is the left side of the guide rail 40, and the other side of the guide rail 40 along the first direction X is the right side of the guide rail 40. The first accommodating cavity 10a1 is located on the left side of the guide rail 40, and the second accommodating cavity 10a2 is located on the right side of the shell 10.

[0082] Optionally, combined Figure 2 and Figure 3 As shown, the guide rail 40 is used to connect the forming platform 101, and the guide rail 40 is located on the side of the accommodating cavity 10a having the top wall 11, the two ends of the bracket 50 are respectively connected to the top wall 11 of the accommodating cavity 10a, and the first routing structure 30 is arranged on the side of the bracket 50 away from the top wall 11 of the accommodating cavity 10a.

[0083] In some embodiments, as Figure 3As shown, the guide rail 40 extends along the second direction Y, wherein the second direction Y is arranged at an angle to the first direction X. A plurality of brackets 50 are provided, each of which is spaced apart along the second direction Y. Each bracket 50 is provided with at least one first wiring structure 30. This allows wiring harnesses connecting other functional components 20 to pass through other first wiring grooves 30a, thereby arranging wiring harnesses connecting different functional components 20 more neatly.

[0084] Figure 5 for Figure 3 A partial enlarged view of point B of the 3D printer base 100 in the illustrated embodiment.

[0085] In some embodiments, combined Figure 3 and Figure 5 As shown, the 3D printer base 100 also includes a second wiring structure 60, which is disposed within the first accommodating cavity 10a1 and / or the second accommodating cavity 10a2. The second wiring structure 60 is provided with a second wiring groove 60a, which extends along a second direction Y, wherein the second direction Y is arranged at an angle to the first direction X. In this way, the second wiring groove 60a can provide a positioning function for the wiring harness within the first accommodating cavity 10a1 and / or the second accommodating cavity 10a2, and can also provide a guiding function for the wiring harness within the first accommodating cavity 10a1 and / or the second accommodating cavity 10a2 along the second direction Y, thereby making the arrangement of the wiring harness within the first accommodating cavity 10a1 and / or the second accommodating cavity 10a2 more orderly. For example, the wiring harness connected to the first functional component 21 can pass through the second wiring groove 60a to connect to other functional components 20.

[0086] In some embodiments, combined Figure 3 and Figure 5 As shown, the second wiring structure 60 includes a wire clamping portion 61, and a second wiring groove 60a is provided through the wire clamping portion 61. The wire clamping portion 61 is connected to the cavity wall of the first accommodating cavity 10a1 and / or the second accommodating cavity 10a2, and the cavity wall completely closes the notch of the second wiring groove 60a to confine the wiring harness within the wire clamping portion 61. In other embodiments, the cavity wall of the accommodating cavity 10a may also partially close the notch of the second wiring groove 60a (not shown in the figure) to confine the wiring harness within the wire clamping portion 61. Optionally, the wire clamping portion 61 is connected to the top wall 11 of the accommodating cavity 10a.

[0087] In some embodiments, as Figure 3As shown, there are multiple second routing structures 60, which are spaced apart from each other along the second direction Y. Furthermore, the multiple second routing structures 60 are positioned adjacent to opposite sides of the first accommodating cavity 10a1 along the first direction X. This allows the multiple wiring harnesses to pass through the multiple second routing structures 60, thereby allowing the multiple wiring harnesses to be routed adjacent to opposite sides of the first accommodating cavity 10a1 along the first direction X. This reduces the overlap of the wiring harnesses with the functional components 20 within the first accommodating cavity 10a1. In this embodiment, there are four second routing structures 60.

[0088] In some embodiments, as Figure 3 As shown, the first functional component 21 is disposed on one side of the first accommodating cavity 10a1 along the second direction Y, and the second functional component 22 is disposed on the side of the second accommodating cavity 10a2 away from the first functional component 21 along the second direction Y. Another functional component 20 is a third functional component 23. The third functional component 23 is disposed within the first accommodating cavity 10a1 and is located on the side of the first functional component 21 along the second direction Y that is closer to the second functional component 22. This facilitates connection of the first functional component 21 to the third functional component 23 via a wiring harness. For example, when the first functional component 21 is a mainboard 21b, this facilitates electrical connection of the mainboard 21b to the third functional component 23 for control. Alternatively, the third functional component 23 may be an AC transformer 23b, which is used to convert externally input AC power into a lower voltage for output.

[0089] In some embodiments, a power interface 70 is provided in the accommodating cavity 10a, and the power interface 70 is provided on one side of the accommodating cavity 10a along the second direction Y close to the second functional component 22 and the third functional component 23, so as to facilitate the input of external AC power to the power supply 22b and the AC transformer 23b from the power interface 70 respectively.

[0090] In some embodiments, as Figure 3 As shown, the other functional components 20 also include a consumable color recognition component 24, a Y-axis drive mechanism 25, and a Z-axis drive mechanism (not shown in the figure). The consumable color recognition component 24, the Y-axis drive mechanism 25, and the Z-axis drive mechanism are respectively connected to the main board 21b via a wiring harness. The wiring harness connected to the main board 21b can pass through the first wiring groove 30a or the second wiring groove 60a to connect to the other functional components 20.

[0091] Alternatively, as Figure 3As shown, the consumables color recognition assembly 24 is disposed on a side of the second accommodating chamber 10a2 away from the second functional component 22 along the second direction Y to more efficiently utilize the space in the second accommodating chamber 10a2. The Z-axis drive mechanism is disposed between the consumables color recognition assembly 24 and the power supply 22b, placing the Z-axis drive mechanism close to the 3D printer bracket 200 for easy connection. The Y-axis drive mechanism 25 is disposed between the first accommodating chamber 10a1 and the second accommodating chamber 10a2, placing the Y-axis drive mechanism 25 close to the guide rail 40. For example, the Y-axis drive mechanism 25 can be disposed at one end of the accommodating chamber 10a along the second direction Y close to the power interface 70. It should be noted that the arrangement of the various functional components 20 can also adopt other arrangements according to usage needs and is not limited here.

[0092] In some embodiments, the 3D printer 1000 further includes external functional components, which are located outside the accommodating cavity 10a and are connected to the main board 21b via an external wiring harness extending into the accommodating cavity 10a. Figure 1 As shown, the two external functional components are the X-axis drive mechanism 300 and the nozzle assembly 400.

[0093] In some embodiments, as Figure 3 As shown, the housing 10 is provided with a wire outlet 10c, which communicates with the first accommodating chamber 10a1. The external wiring harness is passed through the wire outlet 10c to facilitate connection to the mainboard 21b. Optionally, the wire outlet 10c is provided on a side of the first accommodating chamber 10a1 away from the second accommodating chamber 10a2 along the first direction X.

[0094] The 3D printer 1000 provided in the embodiment of the present application, by providing a first wiring structure 30 and a second wiring structure 60, makes the wiring harness routing more orderly, reduces the risk of short circuit caused by the entanglement of different wiring harnesses, avoids waste of space, and facilitates the search and inspection of the target wiring harness during subsequent maintenance.

[0095] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent replacements of the technical solutions of the present application should not depart from the spirit and scope of the technical solutions of the present application.
