Description

Technical Field

[0001] This utility model belongs to the field of vehicle high-voltage power distribution systems, and in particular relates to an MSD blocking device and a vehicle. Background Technology

[0002] The Manual Service Disconnect (MSD) is a core safety component in the high-voltage power distribution system of new energy vehicles, used to physically disconnect the high-voltage circuit during maintenance or inspection. The main components of the MSD can be found in the invention patent application with publication number CN115810520A and the utility model patents with authorization announcement numbers CN221928763U and CN222763333U. During vehicle maintenance and inspection, repair personnel must disconnect the MSD from components such as the high-voltage box according to the safety operation manual to cut off the high-voltage output of the power battery, preventing accidental electric shock to repair personnel while the circuit is still conducting.

[0003] However, after the MSD is removed, there is a risk that unsuspecting personnel may accidentally reinstall the MSD or other external objects may accidentally enter the MSD connection port, causing the circuit to remain open and potentially leading to accidental injury or death.

[0004] To address the aforementioned issues, a utility model patent with authorization announcement number CN220797184U discloses a locking tag device for manual maintenance switches in new energy vehicles. This device is actually a type of MSD (Manual Discharge Device) sealing device, which includes a cover, a handle, and a locking hook. The cover can be placed on top of the MSD socket, and the handle can rotate relative to the cover. The handle is connected to the locking hook, and when the handle rotates, it can drive the locking hook to lock together with the fixing pin of the socket, thereby making the cover stably fastened to the top of the MSD socket and preventing accidental operation by personnel or the entry of foreign objects.

[0005] However, the aforementioned patent does not disclose where or how the device should be placed during normal vehicle operation. In reality, if the placement location is inconvenient for personnel to access, on-site personnel may not choose to use the device to block the MSD socket, thus failing to achieve the desired protective effect.

[0030] To facilitate the use of the MSD sealing device by staff during vehicle maintenance and inspection, the basic technical concept of this invention is to install a dedicated mounting bracket for fixing the MSD sealing device on the side of the MSD socket on the vehicle body. Specifically, the MSD is detachably fixed to the mounting bracket using fastening bolts. Correspondingly, the MSD sealing device has a through hole for the fastening bolts to pass through. When the vehicle is running normally, the MSD sealing device can be fixed to the mounting bracket. When it is necessary to seal the MSD socket, the MSD sealing device can be removed and used immediately, which is convenient and efficient.

[0031] Based on the above concept, the present invention will be further described in detail below with reference to the embodiments.

[0032] Specific embodiments of the vehicle provided by this utility model:

[0033] To make it easier to understand, let's first explain the concept of a standard MSD (Motor Storage Device). For vehicles, this naturally includes the vehicle body; for new energy vehicles, it also includes the power battery. To quickly disconnect the high-voltage circuit during vehicle maintenance or inspection, vehicles are equipped with an MSD. The MSD consists of an MSD plug and an MSD socket. Simply unplugging the MSD plug from the MSD socket disconnects the high-voltage circuit. The MSD can be located on the power battery, or above or below it.

[0034] To prevent accidental contact or foreign object entry into the MSD socket when the MSD plug is unplugged, the vehicle is also equipped with an MSD sealing device (hereinafter referred to as the sealing device). The sealing device is as follows: Figures 1-4 As shown, the device consists of two parts: a cover 1 and a locking handle 2. The cover 1 is mainly used to block the MSD socket when the MSD plug is unplugged. The locking handle 2 can swing relative to the cover 1 to lock the blocking device in the blocking position after the blocking device is installed, so as to prevent personnel from accidentally pulling out the blocking device.

[0035] Unlike existing technologies, the vehicle body is equipped with a dedicated mounting bracket 3 for securing the sealing device. Specifically, the mounting bracket 3 is located beside the MSD socket, for example, it can be welded to the vehicle frame next to the MSD socket. (See reference...) Figure 5 The mounting bracket is equipped with fastening bolts. For example, threaded holes can be provided on the mounting bracket 3, and the fastening bolts are screwed into the threaded holes. Correspondingly, a through hole 101 is provided on the cover 1 of the sealing device to secure the sealing device. The through hole 101 allows the fastening bolts to pass through, thereby fixing the sealing device to the mounting bracket with the fastening bolts. Of course, the through hole 101 should not interfere with the normal use of the locking handle 2. That is, the sealing device is fixed to the mounting bracket 3 with detachable bolts. When the vehicle is running normally, the sealing device can be fixed to the mounting bracket 3. When the sealing device needs to be used, the operator can remove the sealing device from the mounting bracket. Since the sealing device is located next to the MSD socket, the operator can remove it as needed, which is very convenient.

[0036] Specifically, such as Figures 1-3 As shown, two through holes 101 for the fastening bolts are provided, and the two through holes 101 are spaced apart along the length of the cover 1 (i.e., the sealing device) and located in the center of the cover 1 in the width direction. Correspondingly, there are also two fastening bolts connected to the fixing bracket. This improves the reliability of the sealing device's fixation and prevents the sealing device from falling off due to vibrations generated during vehicle operation. Specifically, when fixing the sealing device, the side of the sealing device that is away from the MSD socket during use can be facing towards and pressed tightly against the fixing bracket, i.e. Figure 3 The state shown is fixed on the fixed bracket, which allows for a larger contact area between the cover 1 and the fixed bracket, thus improving the reliability of the fixation.

[0037] To facilitate identification of the sealing device by on-site personnel, in a preferred embodiment, the side of the cover 1 facing away from the MSD socket during sealing is... Figure 1 and Figure 2 The upward-facing side shown is coated with a warning layer, which may be different in color from the regular MSD plug, or the warning layer may be a sprayed message or a specific shape, to remind personnel to identify the sealing device and avoid accidental operation.

[0038] Regarding the design of the locking handle 2, in a preferred embodiment, the locking handle 2 can be identical to the handle (grip) of the MSD plug (e.g., the handle in the background art reference document). This allows the use of the fixing posts on the MSD socket and achieves a better locking effect. Specifically, the locking handle 2 has an overall U-shaped structure, with a rotating shaft 104 provided on the cover 1. The locking handle 2 is rotatably mounted on the rotating shaft 104. Arc-shaped grooves 201 are provided at both ends of the swing axis of the locking handle 2. The arc-shaped grooves 201 are coaxial with the swing axis, i.e., the extension direction of the rotating shaft 104. Simultaneously, the locking handle 2 has an inlet / outlet 202 communicating with the arc-shaped grooves 201, allowing the fixing posts on the MSD socket to enter and exit. Figure 1 For example, when installing the sealing device, first rotate the locking handle 2 to a position that is basically perpendicular to the cover 1, so that the inlet / outlet 202 faces the MSD socket. Push the sealing device towards the MSD socket so that the cover 1 can be fastened to the MSD socket, and the fixing post of the MSD socket can enter the arc groove 201. Then rotate the locking handle 2 to... Figure 1 As shown, the sealing device can be reliably fixed to the MSD socket. Of course, to prevent unauthorized personnel from removing the sealing device, a locking structure is also provided on the cover 1 for locking the locking handle 2 after it is swung to the locking position.

[0039] Specifically, in some embodiments, the locking structure includes a locking protrusion 102, which protrudes from the side of the cover 1 facing away from the MSD socket when the cover is in use for sealing. Figure 1 The upper surface of the cover 1 shown has a lock hole 103 on the locking protrusion 102, which can be used to install a lock. Correspondingly, the locking handle 2 has a channel (which can be a groove or a hole) through which the locking protrusion 102 passes. After the locking handle 2 is rotated to the locked position, the locking protrusion 102 can protrude from the locking handle 2, and the locking handle 2 can be locked by passing a lock through the lock hole 103 to ensure security.

[0040] By employing the above-described locking method, the locking protrusion 102 is positioned on the side of the sealing device facing outwards during use, making it convenient for staff to lock. However, it should be emphasized that in other embodiments, it is not excluded that the locking protrusion 102 may be positioned in other locations, as long as a lock can be installed and the locking protrusion 102 can be swung into place and locked.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features.
