Description

Technical Field

[0001] This invention relates to a common structure for mirror mounting of robot housings, belonging to the field of robot application technology. Background Technology

[0002] With the rapid development of science and technology, robots have been widely used in various fields such as industrial production, logistics and transportation, and service industries, becoming core equipment for improving production efficiency and optimizing service quality. The robot shell, as a key structural component, plays a crucial role in providing sealed protection for internal drive components, circuit modules, sensors, and other core elements. It also provides stable support for the overall robot structure, ensuring the structural integrity and motion stability of the robot during operation, and is the fundamental guarantee for the robot to achieve its various functions.

[0003] However, existing robot shells still have many shortcomings in terms of structural design, manufacturing, use, and performance, as follows: Currently, most mainstream robot shells adopt a one-piece molding structure. While this structure can ensure structural integrity to a certain extent, it is difficult, time-consuming, and costly to develop molds. Moreover, one-piece shells have significant maintenance defects. When a part of the shell is damaged by a collision, the damaged part cannot be replaced individually; the entire shell must be replaced, leading to a significant increase in maintenance costs. Some shells adopt a spliced ​​structure, with asymmetrical designs on the left and right sides. This requires the development of two different sets of molds for production, which also suffers from high mold investment costs and low production efficiency, making it difficult to meet the cost control requirements of large-scale mass production. Existing modular shell fixing methods are relatively simple, mostly using single bolt connections or basic snap-fit ​​joints, lacking multi-dimensional limiting and reinforcing structures. This design results in insufficient connection strength at the shell joints. Under vibration or minor external impacts during robot operation, the joints are prone to loosening, displacement, or even separation. At the same time, the lack of effective internal reinforcement structures at the joints leads to localized weak rigidity, making them susceptible to deformation and severely affecting the overall stability and service life of the robot. Summary of the Invention

[0015] The beneficial effects of this invention are: This invention provides a common structure for mirror mounting of robot shells. By employing a mirror splicing design of two identical lower shells, only one set of molds needs to be developed to produce symmetrical shell components, significantly reducing mold investment costs. The splicing design avoids the problem of needing to develop two separate sets of molds for asymmetrical shells, reducing mold replacement and debugging time, improving production efficiency, and enabling faster fulfillment of large-scale mass production needs. It also allows for the replacement of damaged lower shells or components without replacing the entire shell, greatly reducing maintenance costs. The bolt waist-shaped hole design allows the lower housing to slide along the hole direction during disassembly, facilitating maintenance and component replacement and improving the convenience of installation and maintenance. The locking and engagement of the limit buckle and the female buckle, as well as the locking and engagement of the reinforcing block and the fixing rib, effectively prevent the splice from loosening, shifting or separating under vibration or impact, thus improving the overall stability of the robot structure. The front and rear limiting reinforcing blocks at the splicing seam are engaged with the fixed ribs to form an internal reinforcing structure, which enhances the local rigidity of the splicing seam, reduces the risk of deformation, and extends the service life of the robot. The sealing module achieves effective sealing of the splicing seam, preventing wind, rain and sand from entering and improving the robot's applicability in harsh environments. The limiting mounting plate at the top of the lower shell is assembled to form a diamond-shaped limiting frame, which engages with the limiting mounting slot of the upper shell, enabling rapid positioning and precise installation, thus improving assembly efficiency. The waist-shaped open bolt mounting slot on the limiting mounting plate allows for fine adjustment of the bolt installation position, compensating for minor errors that may occur during assembly and ensuring the tightness and flatness of the connection between the upper and lower shells. The elastic buffer sleeves fitted on the front and rear splicing fixing blocks undergo axial compression deformation when impacted. Combined with the gap between the bolts and threaded holes, they effectively buffer the impact force, avoid damage to components caused by rigid collisions, and reduce the transmission of vibration to internal components.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] Example 1 The present invention provides a common structure for mirror mounting of robot shells, which includes a lower shell 1 and an upper shell 2. The lower shell 1 is located at the bottom of the upper shell 2 and is symmetrically arranged. The two lower shells 1 are spliced ​​and fixed together by a snap-fit ​​fixing part 3, and a receiving cavity for accommodating internal components of the robot is formed between the two lower shells 1. The latching fixing part 3 is located at the edge of the two lower housings 1 facing each other. The latching fixing part 3 includes a positioning post 31 fixed to the lower housing 1, a front splicing fixing block 32, a limiting latch 33, a limiting female latch 34, and a rear splicing fixing block 35. The front splicing fixing block 32 and the rear splicing fixing block 35 are respectively located at both ends of the lower housing 1. The front splicing fixing blocks 32 and the rear splicing fixing blocks 35 at both ends are linearly staggered. One end of the front splicing fixing block 32 and the rear splicing fixing block 35 is fixedly connected to the lower housing 1, and the other end extends outward and is provided with a threaded hole for fixing. The limiting latch 33 and the limiting female latch 34 are respectively located at both ends of the lower housing 1, and one end is fixedly connected to the lower housing 1. The limiting latches 33 and the limiting female latch 34 at both ends are mutually latched and fixed at their opposite ends. The buckle fixing part 3 includes a front limiting reinforcement block 36 and a rear limiting reinforcement block 37. The front limiting reinforcement block 36 and the rear limiting reinforcement block 37 are located at both ends of the lower housing 1 and are staggered. One end of the front limiting reinforcement block 36 and the rear limiting reinforcement block 37 is fixedly connected to the inner wall of the lower housing 1 and extends outward. The lower housing 1 is provided with fixing ribs 38 that match the upper and lower front limiting reinforcement blocks 36 and the rear limiting reinforcement block 37. The robot includes a drive assembly 4 for driving. The drive assembly 4 is located at the bottom of the lower housing 1. The drive assembly 4 includes a main drive wheel 41, an auxiliary drive wheel 42, and a guide wheel 43. The auxiliary drive wheel 42 is symmetrically arranged on both sides of the guide wheel 43. The main drive wheel 41 is located at the snap-fit ​​points of the lower housing 1 on both sides and is connected to the lower housing 1 by a mounting cover 5. The mounting cover 5 is provided with bolt round holes 51 and bolt waist-shaped holes 52 that are connected to the lower housings 1 at both ends. The mounting cover 5 is fixedly connected to the lower housings 1 at both ends through the bolt round holes 51 and bolt waist-shaped holes 52 at both ends. The cavity is provided with a suspension assembly 12 that matches the main drive wheel 41. The lower housing 1 has a limiting mounting plate 11 at the top that matches the upper housing 2. The limiting mounting plate 11 is located on both sides of the top of the lower housing 1 and is gradually widened in a trumpet shape. The upper housing 2 has a limiting mounting groove at the bottom that matches the limiting mounting plate 11. The limiting mounting plate 11 and the upper housing 2 are connected by bolts. The limiting mounting plate 11 has a bolt mounting groove 111 that matches the bolts. The bolt mounting groove 111 is set in a waist-shaped opening.

[0030] In use, the latching and fixing parts 3 at both ends of the lower housing 1 are staggered. The two openings are mirror-assembled relative to the lower housing 1 to form the outer contour of the robot, forming an internal receiving cavity. The two lower housings 1 have the same structure and can be processed using a single model. The two lower housings 1 are fixed by the latching and fixing parts 3, which include a front splicing fixing block 32 and a rear splicing fixing block 35 located at both ends of a single lower housing 1. The front splicing fixing block 32 and the rear splicing fixing block 35 are linearly staggered. During the mirror-assembly of the two lower housings 1, one end of the front splicing fixing block 32 and the rear splicing fixing block 35 are fixedly connected to the corresponding lower housing 1, and the other end extends to be fixed to the corresponding lower housing 1 through a bolt through a threaded hole. The lower housing 1 is provided with positioning posts 31 that match the front splicing fixing block 32 and the rear splicing fixing block 35. The positioning posts 31 are used to position and install the front splicing fixing block 32 and the rear splicing fixing block 35. The bottom of the inner walls of the two lower housings 1 are respectively provided with mutually engaging limiting buckles 33 and limiting female buckles 34. The two lower housings 1 are fixed together by the mutual cooperation of the limiting buckles 33 and limiting female buckles 34. The lower housings 1 are respectively provided with staggered front limiting reinforcement blocks 36 and rear limiting reinforcement blocks 37. The front limiting reinforcement blocks 36 and rear limiting reinforcement blocks 37 are located at both ends of the lower housings 1. One end of the front limiting reinforcement blocks 36 and the rear limiting reinforcement blocks 37 are fixedly connected to the lower housing 1, and the other end extends to the other lower housing 1 to cooperate with the fixing ribs 38 on the lower housing 1 for locking. During the installation of the two lower housings 1, the staggered arrangement avoids the front limiting reinforcement blocks 36 and the rear limiting reinforcement blocks 37 from causing conflict. When the two lower housings 1 are spliced, the front limiting reinforcement block 36 of one housing will abut against the housing wall or corresponding structure of the other housing, and vice versa. This effectively enhances the local rigidity and deformation resistance at the splice joint and acts as an internal reinforcing rib. A drive assembly 4 is installed at the bottom of the lower housing 1. The drive assembly 4 includes a main drive wheel 41, an auxiliary drive wheel 42, and a guide wheel 43. The guide wheel 43 is located at the front and rear ends of the robot for guidance, and the auxiliary drive wheel 42 is located on both sides of the guide wheel 43 for support. The main drive wheel 41 is located at the snap-fit ​​joint of the two lower housings 1. A suspension assembly 12 matching the main drive wheel 41 is provided in the receiving cavity. The suspension assembly 12 and the main drive wheel 41 cooperate with each other to prevent the auxiliary drive wheels 42 from failing to touch the ground during walking, thus preventing the robot from suspending in the air. The mounting points of the two lower housings 1 are equipped with a main drive wheel 41, a guide wheel 42, and a guide wheel 43. The main drive wheel 41 is located inside the mounting cover 5. The mounting cover 5 is provided with bolt round holes 51 and bolt waist-shaped holes 52 that match the two lower housings 1. The two lower housings 1 are threadedly connected to the mounting cover 5 by bolts passing through the bolt round holes 51 and bolt waist-shaped holes 52. One of the lower housings 1 is fixed to the mounting cover 5 by bolt waist-shaped holes 52. During the installation process, the position of the lower housing 1 can be adjusted, and during the disassembly process, the lower housing 1 can be slid along the direction of the bolt waist-shaped holes 52. The lower housing 1 has an upper housing 2 on top. Each lower housing 1 has a limiting mounting plate 11 on both sides of its top. The two limiting mounting plates 11 are flared and gradually expand. The limiting mounting plates 11 on the two lower housings 1 are assembled into a diamond-shaped limiting frame. The bottom of the upper housing 2 has a limiting mounting groove that matches the diamond-shaped limiting frame. The limiting mounting groove engages with the outside of the diamond-shaped limiting frame to further limit the lower housing 1. The limiting mounting plates 11 and the upper housing 2 are fixed together by bolts. The limiting mounting plates 11 have bolt mounting grooves 111 that match the bolts. The bolt mounting position can be finely adjusted within the bolt mounting grooves 111.

[0031] Compared with existing technologies, the two lower housings 1 have identical structures and are assembled using a mirror-image splicing method to form the robot's outer contour, significantly reducing mold development costs. Simultaneously, it reduces mold replacement and debugging time, improves production efficiency, and can more quickly meet the needs of large-scale production. During splicing, one end of the front splicing fixing block 32 and the rear splicing fixing block 35 are respectively fixedly connected to the corresponding lower housing 1, and the other end extends and is fixed through bolts passing through threaded holes. This allows the two lower housings 1 to be connected through multiple fixing points during splicing, increasing the stability and firmness of the splicing and effectively preventing loosening or separation at the splice joint. The mutual engagement of the interlocking limiting buckles 33 and limiting female buckles 34 further secures the two lower housings 1 together. The overall strength of the splicing structure is enhanced, allowing it to better maintain structural integrity under external impact or vibration, thus improving the robot's reliability and durability. When the two lower housings 1 are spliced, the front limiting reinforcement block 36 at one end of one housing and the rear limiting reinforcement block 37 at the other end will engage with the fixing rib 38 on the housing wall of the other lower housing 1, effectively enhancing the local rigidity and deformation resistance at the splicing seam, acting as an internal reinforcing rib. The two lower housings 1 are respectively connected to the mounting cover 5 via bolts passing through the bolt round hole 51 and the bolt waist-shaped hole 52, respectively. The lower housing 1 and the mounting cover 5 are fixed together by bolt slots 52. During installation, the bolt slots 52 allow for adjustment of the position of the lower housing 1, making installation more precise. During disassembly, the lower housing 1 can slide along the direction of the bolt slots 52, facilitating maintenance and component replacement, and improving the convenience of installation and maintenance. The suspension assembly 12 cooperates with the main drive wheel 41 to prevent the front and rear auxiliary drive wheels 42 from failing to touch the ground during movement, thus preventing the robot from suspending in the air. The bottom of the upper housing 2 is provided with a limiting mounting groove that engages with the diamond-shaped limiting frame. The lower housing 1 is further limited outside the diamond-shaped limiting frame, making the installation of the upper housing 2 and the lower housing 1 more precise, enabling rapid positioning, improving assembly efficiency, and enhancing the stability of the connection between the upper and lower housings. The limiting mounting plate 11 is fixed to the upper housing 2 by bolts. The limiting mounting plate 11 is provided with bolt mounting grooves 111 that match the bolts. The bolt installation position can be finely adjusted within the bolt mounting grooves 111, which can compensate for minor errors that may occur during the assembly process, ensuring the tightness and flatness of the connection between the upper housing 2 and the lower housing 1, and improving the overall quality of the product.

[0032] Example 2 Based on the previous embodiment, in this embodiment, the lower housing 1 is provided with sealing modules 6 at both ends for sealing. The sealing module 6 includes a sealing tongue 61 and a sealing slot seat 62 that are snapped into the lower housing 1. The sealing tongue 61 and the sealing slot seat 62 are respectively located at both ends of the lower housing 1. The sealing tongue 61 and the sealing slot seat 62 are snapped into the lower housing 1 by providing a sealing element clamping block 63. The lower housing 1 is provided with sealing element grooves that match the sealing element clamping block 63 on both sides. The interior of the sealing element groove is stepped. The bottom of the sealing element clamping block 63 is provided with an outwardly extending limiting part 631. The limiting part 631 is symmetrically arranged on both sides of the sealing element clamping block 63. The side of the limiting part 631 near the bottom of the sealing element clamping block 63 is linearly and gradually expanded with the sealing element clamping block 63. The sealing slot seat 62 is provided with a sealing groove 621. The sealing groove 621 is flared and gradually narrows inward. The inner wall of the sealing groove 621 is provided with a plurality of sealing limiting teeth 622. The plurality of sealing limiting teeth 622 are located on the inner wall of the sealing groove 621 in a linear arrangement, and there is a gap between the plurality of sealing limiting teeth 622. The sealing groove 621 has a tongue head 611 that matches the sealing groove 621 at one end away from the sealing element clamping block 63. The tongue head 611 has multiple tongue limiting teeth 612 on both sides. The multiple tongue limiting teeth 612 are arranged linearly on the outside of the tongue head 611. The tongue limiting teeth 612 and the sealing limiting teeth 622 are spaced apart. The distance between two adjacent sealing limiting teeth 622 is less than the length of the tongue limiting teeth 612. Both the front splicing fixing block 32 and the rear splicing fixing block 35 are provided with elastic buffer sleeves 7 for buffering. The elastic buffer sleeves 7 are fitted on the front splicing fixing block 32 and the rear splicing fixing block 35. The inner wall of the elastic buffer sleeve 7 is provided with buffer sleeve positioning teeth 71 for limiting. The front splicing fixing block 32 and the rear splicing fixing block 35 are provided with buffer sleeve positioning grooves 321 that match the buffer sleeve positioning teeth 71. The threaded holes on the front splicing fixing block 32 and the rear splicing fixing block 35 are limiting threaded holes. The diameter of the limiting threaded hole is larger than the cross-sectional diameter of the corresponding fixing bolt. The elastic buffer sleeve 7 is provided with threaded holes that match the limiting threaded holes. The fixing bolt passes through the elastic buffer sleeve 7, the front splicing fixing block 32 or the rear splicing fixing block 35 in sequence to fix the two lower shells 1.

[0033] In use, the lower housing 1 has sealing grooves at both ends for installing sealing tongue 61 and sealing slot seat 62. The inner wall of the sealing groove is stepped. The sealing tongue 61 and sealing slot seat 62 are respectively provided with sealing clamping blocks 63 that match the sealing groove. The sealing clamping blocks 63 are inserted into the sealing groove. The sealing clamping blocks 63 are provided with outwardly extending limiting parts 631 on both sides. The limiting parts 631 engage with the stepped inner walls on both sides of the sealing groove to fix the sealing tongue 61, sealing slot seat 62 and lower housing 1. During installation, the sealing slot seat 62 on one lower housing 1 and the sealing tongue 61 on the other lower housing 1 are engaged with each other. The sealing tongue 61 is inserted into the sealing groove 621, and the tongue head 611 of the sealing strip is inserted into the trumpet-shaped tapering sealing groove 621. The tongue limiting tooth 612 and the sealing limiting tooth 622 are intermittently press-fitted, thereby achieving a seal between the sealing tongue 61 and the sealing slot seat 62, which can prevent wind, rain and sand from entering. Elastic buffer sleeves 7 are fitted onto the front splicing fixing block 32 and the rear splicing fixing block 35. The elastic buffer sleeves 7 are made of nitrile rubber. The elastic buffer sleeves 7 are limited and fixed to the front splicing fixing block 32 and the rear splicing fixing block 35 by buffer sleeve positioning teeth 71. The fixing bolts pass through the elastic buffer sleeves 7, the front splicing fixing block 32 or the rear splicing fixing block 35 respectively to achieve splicing and fixing between the two lower shells 1. The diameter of the threaded hole on the front splicing fixing block 32 and the rear splicing fixing block 35 is larger than the diameter of the fixing bolt. With the axial compression of the elastic buffer sleeve, the impact force can be buffered by the deformation of the buffer sleeve and the gap between the bolt and the threaded hole when impacted. This avoids damage to the components caused by rigid collision and reduces the transmission of vibration to internal components.

[0034] Compared with the existing design, after the sealing clamping block 63 is inserted into the sealing slot, the limiting part 631 can be tightly engaged with the stepped inner wall on both sides of the sealing slot, which enhances the fixing effect between the sealing tongue 61, the sealing slot seat 62 and the lower housing 1, and prevents the sealing module 6 from loosening and falling off. During installation, the sealing tongue 61 is inserted into the sealing slot 621, the tongue clamp head 611 is inserted into the tapered sealing slot 621, and the tongue limiting tooth 612 and the sealing limiting tooth 622 are intermittently interference-fitted, which can effectively block the intrusion of wind, rain and sand and dust, and provide a good sealing effect. Both the front-end splicing fixing block 32 and the rear-end splicing fixing block 35 are fitted with elastic buffer sleeves 7. These elastic buffer sleeves 7 are made of nitrile rubber, possessing good elasticity and flexibility. The inner wall of the elastic buffer sleeve 7 is provided with buffer sleeve positioning teeth 71, and the front-end splicing fixing block 32 and the rear-end splicing fixing block 35 are provided with buffer sleeve positioning grooves 321 that match the buffer sleeve positioning teeth 71. This ensures that the elastic buffer sleeve 7 is securely fitted onto the splicing fixing blocks and will not easily fall off during use. When the two lower housings 1 are spliced ​​and fixed, the fixing bolts pass through the elastic buffer sleeve 7, the front-end splicing fixing block 32, or the rear-end splicing fixing block 35 in sequence. When subjected to impact, the elastic buffer sleeve 7 undergoes axial compression deformation. Simultaneously, the gap between the bolt and the threaded hole effectively buffers the impact force, preventing damage to components caused by rigid collisions, reducing the transmission of vibration to internal components, and extending the service life of the robot's internal components.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
