[0058] Figure 1 It is a three-dimensional diagram of a battery mechanism according to an illustrative embodiment of the present utility model. Figure 2 yes Figure 1 The battery mechanism of the exemplary embodiment shown is a three-dimensional view with the case and cover removed.

[0059] According to the battery mechanism provided by the utility model, Figure 1 and Figure 2 As shown, the housing 17 includes a truss assembly 14, a battery 12, a retaining member 11, a blocking member 15, and a bolt 16. The housing 17 has an opening at its top. The truss assembly 14 is disposed within the housing 17, defining a mounting cavity extending along a first direction. The battery 12 is slidably mounted within the mounting cavity and is restricted by the truss assembly 14 from movement in a second direction orthogonal to the first direction. The retaining member 11 is disposed within the mounting cavity and is adapted to press against one end of the battery 12 along the first direction and restrict movement of the battery 12 along a third direction orthogonal to both the first and second directions. The blocking member 15 has a first state in which it presses against the other end of the battery 12 along the first direction to retain the battery 12 in the first direction, and a second state in which it is separated from the battery 12, allowing the battery 12 to be removed from the mounting cavity. The bolt 16 is detachably mounted to the blocking member 15 and the truss assembly 14 to maintain the blocking member 15 in the first state.

[0060] According to the embodiment of the present utility model, Figure 2 As shown, the truss assembly 14 includes a plurality of first transverse beams 142 and a plurality of first longitudinal beams 141. The plurality of first transverse beams 142 define a support surface of the mounting cavity, suitable for supporting the battery 12. The plurality of first longitudinal beams 141 are vertically mounted on the first transverse beams 142, with at least two first longitudinal beams 141 pressing against two opposing end surfaces of the battery 12 along the second direction to define the mounting cavity.

[0061] In an illustrative embodiment, Figure 2As shown, the multiple first cross beams 142 in the truss assembly 14 are connected end to end in sequence to form a bottom frame suitable for supporting the battery, and the upper surface of the bottom frame serves as a support surface. Furthermore, the multiple first longitudinal beams 141 are arranged in pairs, and the two first longitudinal beams 141 in the same pair are symmetrically arranged on both sides of the bottom frame to form a mounting cavity suitable for accommodating the battery 12 with the bottom frame. The spacing between at least one pair of first longitudinal beams 141 is configured to be substantially the same as the width of the battery 12, so as to extend along the second direction (i.e., the width direction of the battery 12, as shown in FIG. Figure 2 The battery 12 is pressed against both sides of the battery 12 and is formed to allow the battery 12 to move in a first direction (i.e., the length direction of the battery 12, as shown in FIG. Figure 2 The battery 12 is provided with a channel through which the battery 12 passes (from the lower right to the upper left as shown), thereby limiting the displacement of the battery 12 in the width direction.

[0062] In a preferred embodiment, Figure 2 As shown, the cross beam 142 in the truss assembly 14 includes but is not limited to a bottom frame configured as a "convex" shape. Accordingly, the longitudinal beams 141 are assembled (including but not limited to riveting, welding, bolting, integral manufacturing or other installation methods) at the connection position of a portion of the cross beam 142, wherein two pairs of longitudinal beams 141 are arranged on the narrow side of the bottom frame (such as Figure 2 The right end is shown in the figure) to form a passage suitable for inserting and removing the battery 12. Furthermore, the box 17 is provided around the truss assembly 14 in the form of a skin and is connected and fixed to the cross beams 142 and / or the longitudinal beams 141 (e.g., riveted) to enclose the truss assembly 14 and the battery 12 within the box 17.

[0063] In this embodiment, the truss assembly 14 serves as the mounting base for the battery 12, and the box 17 is wrapped around the outside of the truss assembly 14, so that the battery structure forms an independent module. The truss assembly 14 constructed by the crossbeams 142 and the longitudinal beams 141 provides a large number of hollow areas inside the box 17 to facilitate the connection and storage of corresponding cables. The displacement of the battery 12 along the first direction, the second direction, and the third direction is respectively restricted by different parts of the battery structure 1, and each part only contacts a part of the battery 12, thereby forming a semi-enclosed structure that is as small as possible, so that a good heat dissipation space can be formed around the battery 12. When disassembling and assembling the battery 12, it is only necessary to remove and assemble the bolts 16 and the blocking member 15, which is very simple to operate.

[0064] In an illustrative embodiment, Figure 2As shown, the stopper 11 is arranged at a position of the installation cavity facing the channel formed by the longitudinal beam 141. Specifically, the side of the stopper 11 facing the channel is configured as a groove structure, so that when the battery 12 is placed, one end of the battery 12 is embedded in the groove structure formed by the stopper 11. In this way, the battery 12 is not only fixed in the first direction (i.e., the length direction of the battery 12), but also fixed in the first direction (i.e., the length direction of the battery 12). Figure 2 from the lower right to the upper left) (as shown in Figure 1 The right end as shown in FIG) is restricted, and based on the groove structure formed by the limiting member 11, the third direction of the battery 12 (ie, the height direction of the battery 12, as shown in FIG) is restricted. Figure 2 upper and lower as shown).

[0065] On this basis, when inserting and removing the battery 12, it can only pass through the channel formed by the longitudinal beam 141. To this end, the blocking member 15 only needs to be placed in the channel after the battery 12 is inserted and pressed against the end of the battery 12 to lock the position of the battery 12; accordingly, when removing the battery 12, it is only necessary to disengage the blocking member 15 from the above-mentioned channel to remove the battery 12, thereby achieving the effect of quick removal and quick installation of the battery 2.

[0066] According to the embodiment of the present utility model, Figure 2 As shown, the limiting member 11 has a vertical portion 111 connected to the supporting surface, and a bent portion 112 formed at the upper end of the vertical portion 111 . The bent portion 112 extends toward the direction close to the first longitudinal beam 141 to press against the upper portion of one end of the battery 12 .

[0067] According to the embodiment of the present utility model, Figure 2 As shown, the bent portion 112 of the limiting member 11 is configured as a concave V-shaped structure, and the lower end of the bent portion 112 presses against the upper portion of the battery 12 .

[0068] In an illustrative embodiment, Figure 2 As shown, the limiting member 11 includes but is not limited to being formed by bending a plate. In detail, in the orthographic projection along the side view of the plate, the plate includes but is not limited to being constructed into a "Z"-shaped structure, the lower end of which extends in a direction parallel to the supporting surface (i.e., the crossbeam 142) and is fixed to the bottom frame built by the crossbeam 142, and the upper end of which is integrally formed with a vertical portion 111 and a bent portion 112, the bent portion 112 extending toward the channel formed by the longitudinal beam 141, thereby forming a long end (such as a longitudinal end) suitable for accommodating the battery 12 between the supporting surface. Figure 2Furthermore, the bent portion 112 forms a concave V-shaped structure. That is, the distance between the end of the bent portion 112 facing the battery and the support surface is greater than the distance between the lower end of the V-shaped structure and the support surface. This not only helps to improve the structural strength of the bent portion, but also helps to accurately guide the battery 12 to be inserted between the stopper 11 and the support surface.

[0069] According to the embodiment of the present utility model, Figure 2 As shown, a handle 13 is provided on the battery 12 .

[0070] In an illustrative embodiment, Figure 2 As shown, a handle 13 is provided on the upper end surface of the battery 12. In detail, the handle 13 is pivotally mounted on the battery 12 so as to be in a vertical state when held by the user and to flip to a state substantially parallel to the upper end surface of the battery 12 when relaxed by the user.

[0071] According to the embodiment of the present utility model, Figure 2 As shown, the blocking member 15 is detachably mounted on the supporting surface by means of bolts 16 .

[0072] In an illustrative embodiment, Figure 2 As shown, the blocking member 15 includes, but is not limited to, a thin plate structure similar to angle steel. Specifically, the bottom of the blocking member 15 is provided with a through hole suitable for inserting a bolt 16, and the truss assembly 14 is also provided with a through hole at a position suitable for installing the bolt 16. Furthermore, when the through hole of the blocking member 15 is aligned with the through hole formed in the truss assembly 14, the bolt 16 can be inserted to secure the blocking member 15, thereby maintaining the blocking member 15 in the first state of pressing against the battery 12. It should be understood that the embodiments of the present invention are not limited to this.

[0073] In another exemplary embodiment, since the cross beams 142 are spaced apart, the location where the blocking member 15 needs to be installed may be located exactly in the hollow area between the two cross beams 142. Therefore, a base plate made of a hard material (such as a metal plate, etc.) can be installed between the two cross beams 142 of this part, and a through hole or groove can be opened on the base plate.

[0074] Figure 3 is a side view of another exemplary embodiment of a battery mechanism showing a reversible barrier. Figure 4 yes Figure 3 A partial enlarged view of part A shows the blocking member in the first state. Figure 5 yes Figure 3 A partial enlarged view of part A shows the blocking member in the second state.

[0075] According to the embodiment of the present utility model, Figures 3 to 5 As shown, the blocking member 15 is reversibly mounted on the support surface, with a first state protruding from the support surface and a second state located within the support surface. The bolt 16 is adapted to penetrate from the side of the first crossbeam 142 to maintain the blocking member 15 in the first state.

[0076] In one exemplary implementation, Figures 3 to 5 As shown, the blocking member 15 adopts a block structure, and its side view forms a roughly L-shaped structure. In detail, the block structure blocking member 15 includes an integrally formed guide portion 152 and a blocking portion 151. The blocking portion 151 and the guide portion 152 are arranged in a roughly vertical direction and are rotatably installed between two opposite crossbeams 142 via a rotating shaft 154. A bottom plate made of a hard material is laid between the two crossbeams 142, and a filling material is filled under the bottom plate. Furthermore, the portion of the filling material located on both sides of the guide portion 152 forms an arc-shaped guide groove 144, and the portion located above the guide groove 144 forms a limit groove 143. The ends of the blocking portion 151 and the guide portion 152 both have arc-shaped chamfers. Furthermore, a threaded hole suitable for passing the bolt 16 is provided on the crossbeam 142.

[0077] Reference Figure 3 and Figure 4 As shown, when the battery 12 is locked, the blocking member 15 rotates upward around the rotation axis 154 so that the blocking portion 151 protrudes from the supporting surface and presses against the end of the battery 12 (as shown in FIG. Figure 3 At this time, by assembling the bolt 16 with the threaded hole provided in the crossbeam 142 and extending the screw rod of the bolt 16 into the limiting hole provided in the guide portion 152, the blocking member 15 can be maintained in the first state.

[0078] Reference Figure 5 As shown, when removing the battery 12, first, rotate the bolt 16 to a position retracted into the crossbeam 142. At this time, the blocking member 15 is not restricted. Therefore, it can be turned down around the rotation axis 154 under the action of its own weight until the blocking portion 151 is embedded in the limiting groove 143, so that the blocking member 15 is roughly flush with the supporting surface (or slightly lower than the supporting surface) to allow the battery 12 to be removed.

[0079] In such an embodiment, compared with Figure 2 In the illustrated embodiment, since the blocking member 15 is mounted on the truss assembly 14 , the battery mechanism 1 is more integrated and the blocking member 15 and the bolt 16 are not easily lost.

[0080] Figure 6 It is a three-dimensional diagram of a mobile device according to an exemplary embodiment of the present invention. Figure 7 yes Figure 6 The schematic embodiment shown is a front view of the driving wheel mechanism 4.

[0081] According to the mobile device provided by the present utility model, Figure 6 and Figure 7 As shown, it includes a chassis 2 and a battery mechanism 1. The battery mechanism 1 is installed on the chassis 2.

[0082] According to the embodiment of the present utility model, Figure 6 and Figure 7 As shown, the chassis 2 includes a first end and a second end, the first end protruding from the second end. The box 17 of the battery mechanism 1 is openably mounted with a cover 18, which is continuous and flush with the upper portion of the first end to form a mounting surface.

[0083] In an illustrative embodiment, Figure 6 and Figure 7 As shown, the first end of the chassis 2 is the front end of the mobile device.

[0084] In an illustrative embodiment, Figure 6 As shown, the chassis 2 includes a truss body formed by splicing a plurality of second cross beams 23 and a plurality of second longitudinal beams 22, wherein the second cross beams 23 and the second longitudinal beams 22 are fixed by, but not limited to, riveting, welding, screw connection, integral manufacturing, or any other connection method. Figure 6 The left end shown in FIG) serves as the front end of the mobile device, i.e., the part facing the main direction of travel, and the second end of the chassis 2 (as shown in FIG) serves as the front end of the mobile device, i.e., the part facing the main direction of travel. Figure 6 The right end shown in FIG. 1 is used as the rear end of the mobile device, that is, the portion facing away from the main direction of travel, to form a front-wheel drive mode. It should be understood that the embodiments of the present invention are not limited thereto.

[0085] For example, the driving wheel mechanism 41 can also be arranged at the second end of the chassis 2 (such as Figure 6 The driven wheel mechanism 3 is provided at the first end of the chassis 2 (as shown in the right end). Figure 6 left end as shown), so that the mobile device forms a rear-wheel drive mode.

[0086] For another example, the first crossbeam 142 and the second crossbeam 23, as well as the first longitudinal beam 141 and the second longitudinal beam 22, can be formed integrally, that is, a portion of the truss body of the chassis 2 can be constructed to form the truss assembly of the battery mechanism. This allows the battery mechanism to be integrated into the mobile device, which helps maintain the integrity of the mobile device.

[0087] In an illustrative embodiment, Figure 6As shown, a pair of driving wheels 41 and a pair of driven wheels are arranged on the chassis 2. The driving wheels are arranged at the first end of the chassis 2, and the driven wheels are arranged at the second end of the chassis 2. In detail, the servo motor 43 suitable for driving the driving wheels 41 is installed at the first end of the chassis 2 (as shown in FIG. Figure 6 Further, the battery mechanism 1 is arranged at the second end of the chassis 2 (as shown in the left end). Figure 6 the right end shown in the figure, so that the battery mechanism 1 and the first end of the chassis 2 (as shown in the figure) Figure 6 The truss bodies formed by the battery mechanism 1 and the chassis 2 (shown as the left end) are at approximately the same height, and the battery mechanism box 17 is sealed by a cover 18. This allows the cover 18 of the battery mechanism 1 and the truss body of the chassis 2 to form a continuous and flat mounting surface, which can conveniently accommodate the robot body, various video capture mechanisms, various detection mechanisms, and various other functional mechanisms suitable for mobile equipment.

[0088] In an exemplary embodiment, the battery mechanism 1 further includes a control unit (e.g., a PLC, or programmable logic controller), a communication unit, and related circuitry. The control unit is communicatively coupled to the servo motor 43 and the communication unit to control the rotation of the servo motor 43 . The control unit also communicates with the outside world via the communication unit to transmit relevant information and control signals.

[0089] In an exemplary embodiment, the battery mechanism 1 is also configured to have a wireless charging function. Furthermore, in order to realize wireless charging of the battery 12 by the battery mechanism 1, an external charging device needs to be configured adaptively.

[0090] For example, the external charging device is equipped with a position sensor, a transmitting host and a transmitting coil suitable for generating electrical pulses; correspondingly, the battery mechanism 1 is equipped with a receiving coil suitable for electromagnetic induction with the transmitting coil, and is also equipped with an inverter and other circuits.

[0091] It should be noted here that the control unit (such as a PLC, or programmable logic controller), the communication unit, and the related equipment and circuits for wireless charging are not the key points of protection of this disclosure. Any device in the field that can be used to control and charge mobile devices can be selected and applied, and no further details will be given.

[0092] According to the embodiment of the present utility model, Figure 6 and Figure 7 As shown, a driving wheel mechanism 4 is configured on the chassis 2. The driving wheel mechanism includes at least one pair of driving wheels 41. The two driving wheels 41 in a pair are symmetrically mounted on both sides of the first end. A servo motor 43 is vertically mounted in the first end, and each servo motor 43 is suitable for driving one driving wheel 41.

[0093] In an illustrative embodiment, Figure 6 and Figure 7 As shown, the driving wheel mechanism 41 further includes a speed reducer 42 . The speed reducer 42 is arranged in the horizontal direction and installed between the servo motor 43 and the first hub of the driving wheel 41 to reduce the torque output by the servo motor 43 and transmit it to the driving wheel 41 .

[0094] In such an embodiment, the servo motor 43 is installed in the installation space formed by the first end of the chassis 2 and is arranged in the vertical direction, occupying the length and width dimensions of the chassis 2 as small as possible, so that the design of the vehicle length and width of the chassis 2 is not limited by the size of the motor, and a shorter and / or narrower chassis 2 can be configured to obtain a smaller turning radius.

[0095] In addition, the servo motor 43 is disposed within the first end of the chassis 2, and the battery mechanism 1 is disposed on the second end of the chassis 2. This also centers the mobile device, and the counterweights at the front and rear ends are relatively balanced, which is beneficial for maintaining the stability of the mobile device during its formation and reducing the possibility of rollover. Furthermore, the truss body formed by the chassis 2 and the battery mechanism 1 are approximately the same height, forming a continuous and large mounting surface to facilitate the installation of other components of the mobile device. Furthermore, the servo motor 43 itself has an electromagnetic brake structure. Therefore, in the event of a power outage or shutdown of the battery mechanism 1, the servo motor 43 can be locked to prevent the vehicle from slipping.

[0096] According to the embodiment of the present utility model, Figure 6 and Figure 7 As shown, a plate-shaped member 21 is provided at the first end of the chassis 2 , and the plate-shaped member 21 is arranged in a vertical direction. One end of the reducer 42 suitable for connecting to the first hub passes through the plate-shaped member 21 .

[0097] According to the embodiment of the present utility model, Figure 6 and Figure 7 As shown, the outer portion of the reducer 42 is provided with an annular member 44 , and the annular member 44 is also connected to the plate-shaped member 21 to mount the driving wheel 41 on the chassis 2 .

[0098] In an illustrative embodiment, Figure 6 and Figure 7 As shown, the plate-shaped member 21 includes, but is not limited to, a rectangular structure. Specifically, the plate-shaped member 21 is vertically mounted on the truss body formed by the chassis 2. Furthermore, an annular member 44 is sleeved around the outer side of the reducer 42 and positioned at a specific axial position of the reducer 42. Furthermore, during assembly of the plate-shaped member 21, the annular member 44 presses against and is connected to one end surface of the plate-shaped member 21, such as by screws or nuts and bolts, to secure the driving wheel mechanism 41 to the chassis 2.

[0099] In an illustrative embodiment, Figure 6 and Figure 7 As shown, the reducer 42 is disposed at the output end of the servo motor 43 and is arranged in a direction perpendicular to the servo motor 43 (i.e., substantially horizontally), thereby forming a substantially L-shaped drive mechanism with the servo motor 43. Furthermore, the output end of the reducer 42 is mounted on the chassis 2 and connected to the first hub of the driving wheel 41, thereby transmitting the torque output by the servo motor 43 to the driving wheel 41 to drive the driving wheel 41.

[0100] In one exemplary embodiment, the driving wheel 41 includes, but is not limited to, pneumatic tires, solid tires, tubeless tires, explosion-proof tires, or any other tire suitable for use on mobile equipment. Furthermore, the outer periphery of the driving wheel 41 is provided with an anti-slip feature for increasing friction between the driving wheel 41 and the working surface. Specifically, this can be a pattern formed on the driving wheel 41 and / or an anti-slip block protruding from the outer periphery of the driving wheel.

[0101] In a preferred embodiment, the anti-slip portion can be an anti-slip block protruding from the outer circumference of the driving wheel 41. Specifically, the anti-slip block includes, but is not limited to, being integrally formed from the same material as the driving wheel 41 (e.g., rubber). Furthermore, multiple anti-slip blocks are arranged in an array along the axial direction of the driving wheel 41 and evenly spaced along the circumference. This helps maintain friction with the driving wheel 41, preventing the mobile device from slipping against the work surface during operation.

[0102] In an illustrative embodiment, Figure 6 As shown, the chassis 2 is further provided with a driven wheel mechanism 3. The driven wheel mechanism includes at least one pair of driven wheels, wherein the two driven wheels in a pair are symmetrically mounted on both sides of the second end of the chassis 2. The driven wheels include but are not limited to omnidirectional wheels.

[0103] In such an embodiment, the omnidirectional wheel used as the driven wheel can roll along the vehicle width direction along the driving direction of the chassis 2 under the action of the differentially driven driving wheel 41, thereby further reducing the turning radius.

[0104] In an illustrative embodiment, Figure 6 As shown, the omnidirectional wheel includes an axle, a main wheel body, a rim, and multiple rollers. The axle is mounted on a chassis 2. The main wheel body is rotatably mounted on the outside of the axle via a second hub. The rim is located circumferentially outside the main wheel body. Multiple rollers are rotatably mounted on the rim, with the axes of the rollers extending orthogonally to the axis of the second hub.

[0105] In an illustrative embodiment, Figure 6As shown, the axle of the omnidirectional wheel is mounted on the chassis 2 and connected to the second end of the base 2. The main wheel body is rotatably mounted on the outer side of the axle via a second hub, allowing it to roll along with the mobile device on a working surface (e.g., the ground) during operation. Specifically, the outer circumference of the main wheel body is provided with multiple rims spaced evenly along the radial direction, extending radially outward. Furthermore, each rim is connected to a roller via a bearing. The outer edge of the roller protrudes from the rim to contact the working surface (e.g., the ground).

[0106] In this embodiment, the driven wheels do not have the freedom to swing relative to the chassis 2. During operation, the mobile device's translation and steering are driven by the driving wheel 41, which in turn causes the driven wheels to follow. In the event of an emergency stop, the driving wheel 41 is directly connected to the chassis (including the truss body) via a speed reducer. This allows the elasticity of the driving wheel (e.g., a rubber tire) to filter vibrations, while the driven wheels are laterally suspended along the width of the chassis 2. This makes them insensitive to vibrations along the length of the mobile device and significantly reduces the fore-and-aft sway of the mobile device, thus adapting to the overall taller chassis structure. This effectively reduces the center of gravity of the load caused by the fore-and-aft sway of the mobile device when the mobile device is carrying a load, preventing the mobile device (including the load) from tipping over in the fore-and-aft direction.
