Description

Technical Field

[0001] This application relates to the field of tail-end host technology, and in particular to assembly tooling and tail-end host. Background Technology

[0002] The tail unit is the core component of the safety protection device at the rear of the train. It is mainly used to monitor the wind pressure at the rear of the train in real time, provide information on the integrity and operating status of the train, and has functions such as automatic alarm, data recording and wireless transmission.

[0003] The main unit at the tail end of the train includes a housing mechanism and a battery mechanism. The housing mechanism has a battery compartment, and the battery mechanism is fixed inside the battery compartment. In related technologies, a snap-fit ​​mechanism is typically assembled on the outer wall of the battery mechanism, and the battery mechanism is snap-fitted and fixed to the battery compartment by direct plugging and unplugging.

[0004] However, to prevent the battery mechanism from loosening due to vibration, the battery compartment and locking mechanism typically use high-strength springs, which increases the difficulty of disassembling the battery mechanism. During operation, the operator needs to use a hanging key to insert into the central lock cylinder of the battery mechanism's cover to unlock it, while keeping the hanging key unlocked and pulling the operating part of the battery mechanism to remove it from the battery compartment. This requires the operator to use both hands to complete the unlocking and disassembly actions, making the operation cumbersome and inefficient. Utility Model Content

[0005] Therefore, it is necessary to provide an assembly tool and a tail-end host to address the difficulty in disassembling the battery mechanism.

[0006] An assembly fixture, comprising:

[0007] The housing mechanism has interconnected battery compartments and openings, and the battery mechanism is installed in the battery compartments through the openings;

[0008] A cover mechanism, one end of which is rotatably mounted on the outer wall of the housing mechanism, and the other end of which includes a fixing component;

[0009] The lock cylinder mechanism is located on the outer wall of the housing mechanism. The lock cylinder mechanism has a locked state and a clearance state. When the lock cylinder mechanism is in the locked state, it is fixedly connected to the fixing component, and the cover mechanism covers the opening to limit the battery mechanism. When the lock cylinder mechanism is in the clearance state, it is disconnected from the fixing component.

[0014] The lock cylinder assembly is rotatably inserted into the mounting hole. One end of the lock cylinder assembly is driven to connect to the bolt assembly to drive the bolt assembly to switch from the locked state to the unleashed state.

[0015] In one embodiment, the latch assembly includes:

[0016] The locking tongue unit is movably disposed in the fixed groove, and the locking tongue unit has a locked state and a clearance state;

[0021] The lock cylinder assembly is disposed between the first lock tongue body and the second lock tongue body to drive the first lock tongue body and the second lock tongue body to move closer to each other, and the reset unit is disposed between the first lock tongue body and the second lock tongue body to drive the first lock tongue body and the second lock tongue body to move away from each other.

[0022] In one embodiment, the end of the first latch body away from the first latching portion includes a first limiting portion, and the first latch body includes a first guide hole that extends along a second direction.

[0023] The second latch body includes a second limiting part at the end away from the second locking part. The second limiting part is located on the side of the first limiting part close to the first locking part. The second latch body includes a second guide hole, which extends along a second direction.

[0024] The lock cylinder assembly includes a guide portion and a drive portion. The guide portion passes through a first guide hole and a second guide hole. The drive portion surrounds the outside of the guide portion and is located between a first limiting portion and a second limiting portion. The drive portion abuts against the first limiting portion and the second limiting portion. The radial length of the drive portion in any direction through the rotation center is not all equal. The drive portion changes the relative distance between the first limiting portion and the second limiting portion to change the relative distance between the first locking bolt body and the second locking bolt body.

[0025] In one embodiment, the reset unit includes:

[0026] The first reset component is disposed between the second limiting part and the first snap-fit ​​part;

[0027] The second reset member is disposed between the first limiting part and the second locking part. The second reset member cooperates with the first reset member to drive the first locking tongue body and the second locking tongue body to move away from each other.

[0028] In one embodiment, the first latching portion includes a first guide surface, which is inclined and configured such that when the cover mechanism is closed, the first guide surface abuts against the fixing component, and the fixing component drives the first latch body to move toward the direction of the second latch body through the first guide surface.

[0029] The second latching part includes a second guide surface, which is inclined and configured such that when the cover mechanism is closed, the second guide surface abuts against the fixing component, and the fixing component drives the second latch body to move closer to the first latch body through the second guide surface.

[0030] In one embodiment, the lock cylinder assembly includes a mating part, and a limiting protrusion is provided in the mounting hole. The mating part engages with the limiting protrusion to limit the rotation angle of the lock cylinder assembly.

[0031] In one embodiment, the housing mechanism includes a housing body and a connecting assembly. The housing body includes a first sidewall and a second sidewall that are connected to each other. An opening is provided on the first sidewall. The connecting assembly includes a connecting body and a fixing part. The connecting body is disposed on the first sidewall and at the opening. A second clearance hole is provided on the connecting body. The projection of the second clearance hole along a first direction is located at the opening. The second clearance hole is used to avoid the battery mechanism. The fixing part is disposed on the second sidewall and has a fixing groove and a first through hole.

[0033] The lock cylinder mechanism is located on the fixed part.

[0034] A tail-end host unit includes a battery mechanism and the assembly fixture provided above. The battery mechanism includes a battery body and an operating part, and the battery body is disposed in the battery compartment.

[0035] In the aforementioned assembly fixture, the battery mechanism is housed within the battery compartment through an opening, while the cover mechanism and locking mechanism are externally located within the housing. When the fixing components of the cover mechanism are fixedly connected to the locking mechanism, the locking mechanism is in a locked state, and the cover mechanism seals the opening to limit the battery mechanism's position, thus securing it. When the fixing components are disconnected from the locking mechanism, the locking mechanism is in a free-moving state, allowing operators to remove the battery mechanism. This design indirectly secures the battery mechanism through the mechanical constraint exerted by the locking mechanism on the cover mechanism, effectively preventing the battery mechanism from loosening or falling off due to vibration during train operation, ensuring power supply stability. Furthermore, the external locking mechanism simplifies the design of the battery mechanism, eliminating the need to integrate a snap-fit ​​mechanism onto the battery mechanism itself. With the above structure, the operator can switch the lock cylinder mechanism between the clearance state and the locked state. When switched to the clearance state, the operator can open the cover and directly remove the battery mechanism from the battery compartment through the opening with one or both hands. This eliminates the need to keep the battery mechanism in the unlocked state and apply force to pull it out, as is required in related technologies. This simplifies the operation steps for the operator to disassemble the battery mechanism, reduces the difficulty of disassembling the battery mechanism and the labor intensity of the operator, and improves the efficiency of the operator in disassembling the battery mechanism.

[0076] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0077] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0078] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0079] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0080] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0081] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0082] See Figures 1 to 3 This application provides an assembly fixture, which includes a housing mechanism 10, a cover mechanism 20, and a locking mechanism 30. The housing mechanism 10 has a battery compartment 111 and an opening 1121 that are in communication with each other. The battery compartment 111 receives a battery mechanism 100 through the opening 1121. One end of the cover mechanism 20 is rotatably disposed on the outer side wall of the housing mechanism 10, and the other end of the cover mechanism 20 includes a fixing component 21. The locking mechanism 30 is disposed on the outer side wall of the housing mechanism 10 and has a locked state and a recessed state. When the locking mechanism 30 is in the locked state, it is fixedly connected to the fixing component 21, and the cover mechanism 20 covers the opening 1121 to limit the battery mechanism 100. When the locking mechanism 30 is in the recessed state, it is disconnected from the fixing component 21. (See also...) Figure 1 The X direction is the first direction, the Z direction is the second direction, and the Y direction is set perpendicular to the X and Z directions.

[0083] Applying the technical solution of this application, the battery mechanism 100 is installed inside the battery compartment 111 through the opening 1121. The cover mechanism 20 and the locking mechanism 30 are externally mounted on the housing mechanism 10. When the fixing component 21 of the cover mechanism 20 is fixedly connected to the locking mechanism 30, the locking mechanism 30 is in a locked state, and the cover mechanism 20 can block the opening 1121 to limit the battery mechanism 100 and complete the fixation of the battery mechanism 100. When the fixing component 21 is disconnected from the locking mechanism 30, the locking mechanism 30 is in an avoidance state, and the operator can remove the battery mechanism 100. With this configuration, the locking mechanism 30 indirectly fixes the battery mechanism 100 through the mechanical constraint acting on the cover mechanism 20, effectively preventing the battery mechanism 100 from loosening or falling off due to vibration during train operation, and ensuring power supply stability. Furthermore, the external locking mechanism 30 simplifies the design of the battery mechanism 100, eliminating the need to integrate a snap-fit ​​mechanism on the battery mechanism 100. With the above structure, the operator can switch the lock cylinder mechanism 30 between the clearance state and the locked state. When switched to the clearance state, the operator can open the cover and directly remove the battery mechanism 100 from the battery compartment 111 through the opening 1121 with one hand or both hands. This eliminates the need to keep the battery mechanism 100 in the unlocked state and apply force to pull it out, as is required in related technologies. This simplifies the operation steps for the operator to disassemble the battery mechanism 100, reduces the difficulty of disassembling the battery mechanism 100 and the labor intensity of the operator, and improves the efficiency of the operator in disassembling the battery mechanism 100.

[0084] See Figures 3 to 8 The fixing component 21 includes a first engaging groove 2111, and the housing mechanism 10 has a fixing groove 1221 and a first through hole 1222 that are interconnected, with the first through hole 1222 being opposite to the first engaging groove 2111. The lock cylinder mechanism 30 includes a support component 31, a bolt assembly 32, and a lock cylinder assembly 33. The support component 31 is fixed at the fixing groove 1221 and has a mounting hole 3121. The bolt assembly 32 is movably disposed within the fixing groove 1221. When in the locked state, the bolt assembly 32 is located within the first engaging groove 2111 through the first through hole 1222; when in the yielding state, the bolt assembly 32 is located outside the first engaging groove 2111. The lock cylinder assembly 33 is rotatably inserted into the mounting hole 3121, and one end of the lock cylinder assembly 33 is drivenly connected to the bolt assembly 32 to drive the bolt assembly 32 from the locked state to the yielding state. This configuration allows the fixing groove 1221 to provide a supporting base for the support assembly 31, facilitating its fixation. The latch assembly 32 can move bidirectionally, and through the precise alignment of the first through hole 1222 with the first locking groove 2111, reliable locking contact and complete separation are achieved. The rotary drive mechanism of the lock cylinder assembly 33 converts rotational motion into linear motion, resulting in low operating torque and a clear tactile feedback, making it easy for operators to perform.

[0085] See Figure 11 and Figure 12 The locking tongue assembly 32 includes a locking tongue unit 321 and a reset unit 322. The locking tongue unit 321 is movably disposed within the fixing groove 1221 and has a locked state and a clearance state. The reset unit 322 is drivenly connected to the locking tongue unit 321 to drive the locking tongue unit 321 to switch from the clearance state to the locked state. This configuration enables the locking tongue assembly 32 to have an automatic return function, restoring it to the locked state without manual intervention, thereby improving the convenience of using the assembly tooling.

[0086] See Figures 3 to 5The fixing component 21 further includes a second latching groove 2121. The first latching groove 2111 and the second latching groove 2121 are spaced apart along a second direction. The housing mechanism 10 further includes a second through hole 1223, which communicates with the fixing groove 1221 and is disposed opposite to the second latching groove 2121. The latching bolt unit 321 includes a first latching bolt body 3211 and a second latching bolt body 3212. The first latching bolt body 3211 is close to the first latching groove 2111. The end of the first latching bolt body 3211 away from the second latching bolt body 3212 includes a first latching portion 32111, which can be located in the first latching groove 2111 through the first through hole 1222. The second latch body 3212 is located near the second locking groove 2121. The end of the second latch body 3212 away from the first latch body 3211 includes a second locking portion 32121, which can be located within the second locking groove 2121 through the second through hole 1223. The lock cylinder assembly 33 is disposed between the first latch body 3211 and the second latch body 3212 to drive the first latch body 3211 and the second latch body 3212 to move closer to each other. The reset unit 322 is disposed between the first latch body 3211 and the second latch body 3212 to drive the first latch body 3211 and the second latch body 3212 to move away from each other. This arrangement creates a symmetrical locking structure with the first locking groove 2111 and the second locking groove 2121 spaced apart, resulting in a more balanced and stable force distribution on the housing mechanism 10 when the latch unit 321 is in the locked state. The coordinated use of the first latch body 3211 and the second latch body 3212 ensures the locking effect of the latch unit 321 when it is in the locked state, effectively preventing loosening on one side. Simultaneously, the independent design of the first latch body 3211 and the second latch body 3212 reduces the difficulty of switching the latch unit 321 between the locked and unblocking states, and facilitates the assembly, disassembly, replacement, and maintenance of the latch unit 321, thus improving the system's reliability. The lock cylinder assembly 33 is positioned between the first latch body 3211 and the second latch body 3212, achieving both synchronous control of the first latch body 3211 and the second latch body 3212 and a more rational distribution of operating force. The symmetrical arrangement of the first latching portion 32111 and the second latching portion 32121, through the precise alignment of the first through hole 1222 and the second through hole 1223, ensures the contact area and positioning accuracy of the first latching portion 32111 and the second latching portion 32121 with the first latching groove 2111 and the second latching groove 2121 respectively during locking. The design of the reset unit 322 located between the two bolt bodies makes full use of space, making the overall structure more compact. The linkage mechanism between the lock cylinder assembly 33 and the first bolt body 3211 and the second bolt body 3212 converts the rotational motion into symmetrical linear motion, resulting in high transmission efficiency and effortless operation.

[0087] See Figures 11 to 14 The first latch body 3211 includes a first limiting portion 32112 at one end away from the first engaging portion 32111, and the first latch body 3211 includes a first guide hole 32113 extending along a second direction. The second latch body 3212 includes a second limiting portion 32122 at one end away from the second engaging portion 32121, and the second limiting portion 32122 is located on the side of the first limiting portion 32112 close to the first engaging portion 32111, and the second latch body 3212 includes a second guide hole 32123 extending along a second direction. The lock cylinder assembly 33 includes a guide portion 331 and a drive portion 332. The guide portion 331 passes through a first guide hole 32113 and a second guide hole 32123. The drive portion 332 surrounds the guide portion 331 and is positioned between a first limiting portion 32112 and a second limiting portion 32122. The drive portion 332 abuts against the first limiting portion 32112 and the second limiting portion 32122. The radial length of the drive portion 332 in any direction through the rotation center is not entirely equal. The drive portion 332 changes the relative distance between the first limiting portion 32112 and the second limiting portion 32122 to change the relative distance between the first latch body 3211 and the second latch body 3212. This configuration ensures that the parallel arrangement of the first guide hole 32113 and the second guide hole 32123 forms a precise movement track, guaranteeing that the first latch body 3211 and the second latch body 3212 remain parallel and aligned during movement. The through-type design of the guide part 331 not only provides a stable motion reference but also plays a role in preventing deflection, effectively preventing the first latch body 3211 and the second latch body 3212 from twisting during movement. The stepped arrangement of the first limiting part 32112 and the second limiting part 32122 creates a compact driving space. The contact method between the drive part 332 and the first limiting part 32112 and the second limiting part 32122 converts rotational motion into precise linear displacement. The non-uniform diameter design of the drive part 332 enables the latch unit 321 to switch from the locking state to the avoidance state through its contour curve. The eccentric structure design of the drive part 332, through the change of the rotation radius, achieves the synchronous opposite or opposite movement of the first latch body 3211 and the second latch body 3212 through rotational action alone. The above structure simplifies the operation process and improves the transmission accuracy.

[0088] In some embodiments, the drive unit 332 may be a cam structure.

[0089] In this application, the drive unit 332 has a parallelogram cross-section along the second direction. The drive unit 332 includes two opposing first drive surfaces 3321 and two opposing second drive surfaces 3322. The length of the first drive surface 3321 is greater than the length of the second drive surface 3322, and the adjacent first drive surfaces 3321 and second drive surfaces 3322 are rounded.

[0090] Furthermore, the first abutment surface 321121 and the second abutment surface 321221 are inclined, allowing the first driving surface 3321 and the second driving surface 3322 to contact the first abutment surface 321121 and the second abutment surface 321221. This arrangement facilitates the driving unit 332 in driving the first latch body 3211 and the second latch body 3212 to move away from each other, ensuring smooth operation of the driving unit 332 during the driving process.

[0091] In some embodiments, the operator can select the tilting direction and tilting angle of the first contact surface 321121 and the second contact surface 321221 as needed.

[0092] In some embodiments, platform structures are provided at both ends of the first abutment surface 321121 and the second abutment surface 321221 to position the first driving surface 3321 and the second driving surface 3322, so as to prevent the driving part 332 from falling off from the first abutment surface 321121 or the second abutment surface 321221 during rotation.

[0093] See Figure 13 In this application, the guide section 331 includes a first guide section 3311 and a second guide section 3312. The diameter of the first guide section 3311 is smaller than the diameter of the second guide section 3312. The first guide section 3311 is slidably inserted into the first guide hole 32113, and the second guide section 3312 is slidably inserted into the second guide hole 32123. This arrangement facilitates the assembly of the first latch body 3211, the second latch body 3212, and the lock cylinder assembly 33.

[0094] See Figure 3 The lock cylinder mechanism 30 also includes a bearing 34, which is fixed on the support assembly 31, and the second guide section 3312 is rotatably inserted into the bearing 34.

[0095] See Figure 11 and Figure 15The reset unit 322 includes a first reset member 3221 and a second reset member 3222. The first reset member 3221 is disposed between the second limiting part 32122 and the first engaging part 32111. The second reset member 3222 is disposed between the first limiting part 32112 and the second engaging part 32121. The second reset member 3222 cooperates with the first reset member 3221 to drive the first latch body 3211 and the second latch body 3212 to move away from each other. This arrangement ensures that the first latch body 3211 and the second reset member 3222 move synchronously and the same distance, and the cooperative work of the second reset member 3222 and the first reset member 3221 ensures the synchronicity and stability of the two latch bodies during the reset process. Furthermore, the arrangement of the first reset member 3221 and the second reset member 3222 makes full use of the internal space of the first latch body 3211 and the second latch body 3212, making the structure more compact and reasonable.

[0096] In some embodiments, the first reset member 3221 and the second reset member 3222 are springs.

[0097] In this application, when the two first driving surfaces 3321 abut against the first abutting surface 321121 and the second abutting surface 321221 respectively, the locking tongue unit 321 is in a locked state, and when the two second driving surfaces 3322 abut against the first abutting surface 321121 and the second abutting surface 321221 respectively, the locking tongue unit 321 is in a yielding state.

[0098] See Figure 3 , Figure 4 , Figure 11 and Figure 12 The first engaging portion 32111 includes a first guide surface 321111, which is inclined. The first guide surface 321111 is configured such that when the cover mechanism 20 is closed, it abuts against the fixing component 21, and the fixing component 21 drives the first latch body 3211 to move closer to the second latch body 3212 via the first guide surface 321111. The second engaging portion 32121 includes a second guide surface 321211, which is inclined. The second guide surface 321211 is configured such that when the cover mechanism 20 is closed, it abuts against the fixing component 21, and the fixing component 21 drives the second latch body 3212 to move closer to the first latch body 3211 via the second guide surface 321211. With this configuration, the first guide surface 321111 and the second guide surface 321211 achieve automatic locking of the first locking tongue body 3211 and the second locking tongue body 3212 when the cover mechanism 20 is closed, reducing the labor intensity of the operators.

[0099] Specifically, a first groove 32114 is provided on the first snap-fit ​​part 32111, and one end of the first reset member 3221 is located in the first groove 32114. This arrangement can prevent the first reset member 3221 from falling off and facilitate the positioning of the first reset member 3221.

[0100] Furthermore, the first locking tongue body 3211 includes a first connecting portion 32115, and the first engaging portion 32111 and the first limiting portion 32112 are located on the same side of the first connecting portion 32115.

[0101] Specifically, a second groove 32124 is provided on the second snap-fit ​​part 32121, and one end of the second reset member 3222 is located in the second groove 32124. This arrangement can prevent the second reset member 3222 from falling off and facilitate the positioning of the second reset member 3222.

[0102] Furthermore, the second latch body 3212 includes a second connecting portion 32125, a second engaging portion 32121 and a second limiting portion 32122 located on the same side of the second connecting portion 32125.

[0103] Specifically, during use, the battery mechanism 100 is placed into the battery compartment 111, the cover mechanism 20 is closed and pressed tightly, thereby locking the cover mechanism 20, and the battery mechanism 100 is installed. During disassembly, the matching key is inserted into the lock cylinder assembly 33 and rotated, so that the first reset member 3221 and the second reset member 3222 are compressed. At this time, the first latch body 3211 and the second latch body 3212 move towards each other, and the latch unit 321 switches from the locked state to the avoidance state. The cover mechanism 20 is opened and the battery mechanism 100 is removed. At this time, the operator releases the matching key, and the first reset member 3221 and the second reset member 3222 cooperate to drive the first latch body 3211 and the second latch body 3212 to switch from the avoidance state to the locked state.

[0104] See Figure 10 and Figure 13 The lock cylinder assembly 33 includes a mating part 333 and a limiting protrusion 3122 provided within the mounting hole 3121. The mating part 333 engages with the limiting protrusion 3122 to limit the rotation angle of the lock cylinder assembly 33. This configuration creates a reliable rigid stop structure through the engagement of the mating part 333 and the limiting protrusion 3122. This allows for precise control of the rotation range of the lock cylinder assembly 33 within a predetermined angle, ensuring sufficient operating stroke while preventing damage to the mechanism due to excessive rotation. The rigid stop of the limiting protrusion 3122 provides a clear tactile feedback of the endpoint, allowing the operator to clearly perceive the rotation limit position.

[0105] In this application, the limiting protrusion 3122 is a prism structure, and the side of the limiting protrusion 3122 cooperates with the limiting protrusion 3122 to limit the rotation angle of the lock cylinder assembly 33.

[0106] In some embodiments, the limiting protrusion 3122 is a triangular prism.

[0107] See Figure 1 , Figure 3 and Figure 16 The housing mechanism 10 includes a housing body 11 and a connecting assembly 12. The housing body 11 includes a first sidewall 112 and a second sidewall 113 connected to each other. An opening 1121 is provided on the first sidewall 112. The connecting assembly 12 includes a connecting body 121 and a fixing part 122. The connecting body 121 is provided on the first sidewall 112 and at the opening 1121. A second clearance hole 1211 is provided on the connecting body 121. The projection of the second clearance hole 1211 along a first direction is located at the opening 1121. The second clearance hole 1211 is used to avoid the battery mechanism 100. The fixing part 122 is provided on the second sidewall 113. A fixing groove 1221 and a first through hole 1222 are provided on the fixing part 122. The cover mechanism 20 also includes a cover body 22, one end of which is hinged to the connecting body 121. A first clearance hole 221 is provided on the cover body 22, the projection of which along a first direction is located at the opening 1121. The first clearance hole 221 is used to avoid the battery mechanism 100. An angle exists between the cover body 22 and the fixing component 21. A lock cylinder mechanism 30 is disposed on the fixing part 122. This arrangement allows for smooth opening and closing of the cover body 22 and the connecting body 121 through a hinged design. The alignment of the first clearance hole 221 and the second clearance hole 1211 ensures unobstructed installation and removal of the battery mechanism 100. Furthermore, the lock cylinder mechanism 30 and the opening 1121 are located on different planes, avoiding interference between the lock cylinder mechanism 30 and the battery mechanism 100, further facilitating the placement and removal of the battery mechanism 100.

[0108] In some embodiments, the connecting body 121 and the fixing part 122 are fixed to the housing body 11 by bolts.

[0109] In some embodiments, one end of the cover body 22 is hinged to the connecting body 121 via a pivot 43.

[0110] See Figure 1 In this application, the fixing component 21 includes a first fixing body 211 and a second fixing body 212. The first fixing body 211 is provided with a first snap-fit ​​groove 2111 and is threadedly connected to the top of the cover body 22 by bolts. The second fixing body 212 is provided with a second snap-fit ​​groove 2121 and is threadedly connected to the bottom of the cover body 22 by bolts.

[0111] Specifically, in this application, a first inclined structure is provided on the first fixed body 211. The first inclined structure gradually tilts upward in a direction away from the cover body 22. The first guide surface 321111 has the same tilt direction as the first inclined structure. The first guide surface 321111 and the first inclined structure can be in surface contact. When the cover mechanism 20 is closed, the first guide surface 321111 is in surface contact with the first inclined structure. During the closing process, the first inclined structure can drive the first locking tongue body 3211 to move closer to the second locking tongue body 3212 through the first guide surface 321111. When the first guide surface 321111 and the first inclined structure are disconnected, the first reset member 3221 drives the first locking tongue body 3211 to move away from the second locking tongue body 3212, so that the first locking part 32111 moves into the first locking groove 2111, thereby realizing the locking of the first locking tongue body 3211 and the first locking groove 2111.

[0112] Furthermore, the second fixed body 212 is provided with a second inclined structure. The second inclined structure gradually tilts downward in a direction away from the cover body 22. The second guide surface 321211 has the same tilt direction as the second inclined structure. The second guide surface 321211 and the second inclined structure can be in surface contact. When the cover mechanism 20 is closed, the second guide surface 321211 is in surface contact with the second inclined structure. During the closing process, the second inclined structure can drive the second latch body 3212 to move closer to the first latch body 3211 through the second guide surface 321211. When the second guide surface 321211 and the second inclined structure are disconnected, the second reset member 3222 drives the second latch body 3212 to move away from the first latch body 3211, so that the second locking part 32121 moves into the second locking groove 2121, thereby realizing the locking of the second latch body 3212 and the second locking groove 2121.

[0113] This configuration further ensures the smooth movement of the first latch body 3211 and the second latch body 3212.

[0114] In some embodiments, a lifting component 13 is provided on the first sidewall 112, and the lifting component 13 is hinged to the first sidewall 112, which facilitates the operator to pick up the housing body 11 and the assembly tooling.

[0115] See Figures 8 to 10The support assembly 31 includes a cover plate 311 and a limiting member 312. The protrusion of the limiting member 312 is located within the groove of the cover plate 311, and the limiting member 312 is welded and fixed to the cover body. The limiting member 312 has a mounting hole 3121 and a limiting protrusion 3122. Further, a groove for placing the bearing 34 is provided on the side of the cover plate 311 away from the limiting member 312, thereby fixing the bearing 34. The cover plate 311 and the fixing part 122 are fixedly connected by bolts.

[0116] See Figure 4 Furthermore, the support assembly 31 also includes a baffle 313, which covers the outside of the cover plate 311 to protect the cover plate 311 and prevent the bolts on the cover plate 311 from rusting.

[0117] See Figure 17 A sealing strip 42 is provided between the connecting body 121 and the first side wall 112, and a sealing ring 41 is provided between the connecting body 121 and the battery mechanism 100.

[0118] See Figure 4 and Figure 18 Multiple shock absorbers 44 are fixed to the cover body 22 by screws. This arrangement can prevent the cover body 22 from colliding with the battery mechanism 100, thereby preventing damage to the battery mechanism 100 and improving the service life of the battery mechanism 100.

[0119] See Figure 17 Another embodiment of this application provides a tail-end host, which includes a battery mechanism 100 and the assembly fixture provided above. The battery mechanism 100 includes a battery body 110 and an operating part 120. The battery body 110 is disposed in the battery compartment 111, and the operating part 120 passes through the first clearance hole 221. This arrangement can avoid interference between the cover body 22 and the operating part 120, and at the same time facilitates the disassembly and placement of the battery mechanism 100.

[0120] The operating part 120 is a handle.

[0121] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
